Definitions
- the present invention relates to a securing device with a locking bar, which can be arranged as required transversely in front of the closed wing of a window or door to secure the wing against opening.
- the fitting provided for mounting the sash on the frame already has a locking function.
- the security of the lock in particular against violent breaking open or prying open, such as in the event of a break-in, can, however, be significantly improved by the additional provision of a security device on the window or door.
- securing devices can provide additional connection points between the sash and the frame of the window or door. With each additional connection point, more force has to be used to break the window or door, making it difficult to break in.
- safety devices generally have to be mounted on the frame on the one hand and on the wing on the other hand, which can damage the frame and in particular the wing.
- the landlord's consent to such a structural intervention in the window or door may be required for tenants, especially since securing devices attached to the sash can often not be removed satisfactorily.
- the locking bar which is fixed transversely in front of the wing in order to secure the closed wing in such a way that it stands in the way of an opening movement of the wing.
- the locking bar can be attached horizontally or vertically. In principle, however, it can be installed transversely in front of the sash in any orientation that is suitable for securing the closed sash on site. Even if the usual locking function of the window or door fitting is then overcome, the sash remains secured against opening by the locking bar, so that boarding through the window or door can be prevented.
- the locking bar is stably anchored.
- the locking bar advantageously does not need to be anchored to the sash or to the frame of the window or door. Because to fasten the locking bar transversely in front of the closed window, the locking bar can instead be anchored to the reveal or in the adjacent wall area of the window or door, i.e. typically in solid masonry or concrete. This not only has the advantage that the window or door, in particular the sash of the window or door, remains undamaged, but also that particularly high forces can be supported in this way.
- One way of anchoring the locking bar in the area of the reveal of the window or door is to provide a hole or other recess in the reveal, on each of two opposite sides of the window or door, into which the locking bar is inserted with a respective end .
- Such a fastening of the locking bar not only requires that the bores are precisely aligned, in particular exactly aligned, but also that the locking bar is variable in length in order to be positioned between the reveal in front of the wing and then with both of them Engage ends in opposite directions in a respective bore.
- the locking bar must be designed, for example, in the manner of a telescopic bar or have bars that can be extended on both sides. Such mechanisms are mechanically less stable when extended as a rigid bar of fixed length, also technically complex and therefore cause comparatively high costs.
- Securing devices with telescopic locking bars which engage axially, ie in the direction of their longitudinal extent, in receptacles of anchoring elements fastened to the reveal of a window or a door to be secured are, for example DE 93 10 441 U1 and DE 93 08 293 U1 known. These locking bars themselves have no locking device, but can be locked in a coupled state by means of a locking device provided on the respective anchoring element, which engages in an annular groove of the locking bar. In contrast, the anchoring element itself does not engage in the locking bar.
- Another safety device is out DE 10 2015 006 162 A1 known.
- the safety device It is also important for the reliability of the safety device that it can be used easily and comfortably. Because if the securing of the wing by means of the securing device is cumbersome, this often means that the securing device is not used consistently.
- the securing device comprises at least one anchoring element which is designed to be permanently installed on one side of the window or the door in the region of a reveal of the window or the door.
- the locking bar can be arranged particularly stably transversely in front of the closed sash.
- the locking bar is in particular arranged transversely in front of the wing in that the locking bar extends along its longitudinal axis from one side of the wing to the opposite side, the longitudinal axis being aligned at least substantially parallel to the wing plane.
- the locking bar does not have to interact directly with the masonry or the concrete, but can interact with the anchoring element, which, as described below, is especially designed for a simple and comfortable and yet resistant Coupling can be formed with the locking bar.
- the anchoring element is permanently installed, for example firmly embedded in the reveal, e.g. screwed in, dowelled or anchored using injection mortar.
- the fixing of the anchoring element in the reveal can be optimized in this way with a view to high strength and resilience.
- Injection mortar anchoring has the additional advantage that assembly inaccuracies, e.g. due to the running drill, can be equalized.
- the anchoring element has a coupling section which, in the assembled state of the anchoring element, projects in the direction of the opposite side of the window or door.
- the coupling section preferably protrudes beyond the reveal in the direction of the opposite side of the window or door, in particular if the anchoring element is at least partially inserted into the reveal.
- the coupling section can, for example, be at least substantially cone-shaped.
- the coupling section can protrude in particular insofar as it extends between an end connected to the remaining anchoring element and an oppositely oriented free end, so that the coupling section, apart from the connected end, represents a separate structure from the remaining anchoring element, which is therefore special can be used to couple the locking bar.
- the direction in which the coupling section protrudes is defined by the position of the free end relative to the connected end of the coupling section.
- the direction into which the coupling section protrudes correspond to the orientation of a longitudinal axis of the coupling section or an axis of symmetry, to which the coupling section is at least substantially symmetrical.
- the locking bar has a locking device and at least one first end section with a coupling receptacle, the end section being designed to be detachably coupled to the anchoring element by the coupling section of the anchoring element engaging in the coupling receptacle of the first end section of the locking bar in a coupling state of the securing device ,
- the first end section is in particular formed on one of two opposite ends of the longitudinal extension of the locking bar, which preferably extends with an at least predominantly constant cross section and at least essentially a straight course along a longitudinal axis.
- the locking bar does not need to intervene in the reveal. Rather, just the other way round, an anchoring element mounted in the region of the reveal engages with a coupling section in the locking bar, which for this purpose has a coupling receptacle at its first end section.
- the locking bar does not have to be variable in length for such a coupling, so that it can have a comparatively simple and thus constantly stable structure.
- the locking bar can preferably be easily cut to length.
- the locking bar can have a body that can be cut to length, with end sections the locking bar, which are designed for cooperation with a respective anchoring element, can be formed by end elements which are separate from the base body but can be connected to the base body, as will be explained further below. If the length of the locking bar essentially corresponds to the distance between two opposite sides of the reveal, it can advantageously be simply placed on the window sill of a particular window when not in use.
- the locking rod and the anchoring element are coupled to one another by the engagement of the coupling section of the anchoring element in the coupling receptacle of the first end section of the locking bar, but - at least initially - can be detached from one another.
- the first end section of the locking bar can be locked to the anchoring element by means of the locking device. In other words, the releasability can be prevented by locking as required.
- the coupling state has two alternative security levels: an unlocked coupling state in which the first end portion of the locking bar is coupled to the anchoring element so that the locking bar is supported by the anchoring element in its arrangement transversely in front of the closed wing of the window or door, but can be released from the anchoring element for a regular opening of the wing; and a locked coupling state in which the coupling cannot be released easily - namely not without a previous unlocking (i.e. returning to the unlocked coupling state), for which preferably the availability of a locking secret, e.g. via a key assigned to the locking device.
- the locking bar By providing an unlocked coupling state in which the locking bar is already coupled to the anchoring element, the locking bar is released but is still possible in principle, the handling of the safety device is simplified. This is because the locking bar can initially be stably arranged in front of the closed sash and is also held in this position in the coupling state before the locking bar can be additionally locked in a subsequent step in order to reliably prevent unauthorized loosening of the locking bar. When locking the locking bar is thus already pre-fixed and therefore advantageously does not need to be held by hand. In a corresponding manner, the removal of the locking bar for releasing the wing is simplified, since the locking bar remains (but now detachably) coupled to the anchoring element after unlocking, so that the locking bar does not have to be held by hand even when unlocking.
- the coupling receptacle of the first end section of the locking bar is preferably arranged in a fixed position on the locking bar at least insofar as it does not have to be displaced relative to the rest of the locking bar, in particular to a base body of the locking bar, for coupling the locking bar to the first anchoring element. Rather, the coupling section of the anchoring element can preferably be introduced into the coupling receptacle simply by placing the locking bar with the coupling receptacle on the coupling section.
- the first end section of the locking bar and the anchoring element are designed with respect to one another in such a way that for coupling the first end section to the anchoring element and / or for releasing the first end section from the anchoring element, the first end section is transverse, ie in particular essentially perpendicular the direction in which the coupling section protrudes and / or is to be displaced transversely to the longitudinal axis of the locking bar.
- the anchoring element can be mounted on a left side of the window or door in the region of the reveal, while its coupling section points to the opposite right side (or vice versa), so that the locking bar can be attached at least essentially horizontally aligned transversely in front of the closed wing (although in principle other orientations are of course also conceivable).
- the coupling of the first end section of the locking bar to the anchoring element can be carried out by placing the first end section on the anchoring element, in particular from above, from the front (towards the sash level) or from below.
- Attaching from above or below has the advantage over attaching from the front that an opening movement of the sash does not act on the locking bar in the decoupling direction, but perpendicular to it, whereby the sash is more reliably secured against opening since the level of security is ensured in all directions , Furthermore, placing from above has the advantage over placing from below that gravity does not act in the decoupling direction.
- the coupling receptacle of the first end section of the locking bar has an open peripheral section and a closed peripheral section, the first end section of the locking bar being designed to be placed on the anchoring element in a direction transverse to the longitudinal axis of the locking bar by the coupling section of the anchoring element is inserted into the coupling receptacle through the open peripheral section of the coupling receptacle, and in the coupling state of the securing device the coupling peripheral section of the anchoring element is partially encompassed by the closed peripheral section of the coupling receptacle.
- the open circumferential section and the closed circumferential section can form respective parts of a region which surrounds the coupling receptacle circumferentially, in particular in the circumferential direction around the longitudinal axis of the locking bar.
- the open circumferential section and the closed circumferential section can jointly cover the entire circumference of the coupling receptacle form with respect to the longitudinal axis of the locking bar, ie the open peripheral portion and the closed peripheral portion are complementary to each other along the entire circumference of the coupling receptacle.
- the closed peripheral section is preferably closed insofar as it is not possible to remove the coupling section of the anchoring element received in the coupling receptacle through the closed peripheral section surrounding it.
- the closed peripheral section can delimit the coupling receptacle as a kind of wall in the radial direction, in particular to the longitudinal axis of the locking bar.
- the open peripheral section is open insofar as the coupling section of the anchoring element can be inserted into the coupling receptacle through the open peripheral section and can in principle also be removed again.
- the closed peripheral section can have at least essentially a U-shape or a C-shape, in the middle of which the coupling receptacle is formed.
- the open peripheral section which then corresponds to the area between the two ends of the U-shape or the C-shape, it can be determined from which radial direction the locking bar with its first end section is to be placed on the anchoring element.
- the open circumferential section preferably extends only over such a small part of the total circumference around the coupling receptacle that the coupling section of the anchoring element can be inserted into the coupling receptacle or removed from the coupling receptacle essentially only from a single angular direction. In principle, insertion or removal in the axial direction may also be possible.
- the coupling section of the anchoring element has, at a free end pointing in the direction in which it protrudes, a circumferential widening which is in the coupling state the securing device is engaged by the coupling receptacle of the first end section of the locking bar.
- the coupling section with the circumferential widening is preferably designed in the manner of a mushroom head pin or a screw head, in particular the screw head of a cylinder head screw.
- Such a shape of the coupling section is not only useful for reaching behind, but also enables the locking bar with a coupling receptacle of a second end section to be slipped longitudinally onto the coupling section of a respective anchoring element and then to have a degree of freedom of movement that allows the locking bar to pivot in with its first end section on the coupling section of a further anchoring element, as will be explained further below.
- the anchoring element can comprise a screw, for example designed according to DIN, the screw head of which together with an adjacent part of the screw shaft forms the coupling section of the anchoring element.
- the use of such a simple component, in particular a standard component, to form the coupling section contributes to low production costs without the reliability of the securing device being impaired.
- the safety level can be influenced by choosing a suitable strength class of the cylinder head screw.
- the strength class is preferably about 8.8 or 10.9, with 8.8 being sufficient.
- the circumferential widening of the coupling section is preferably a closed circumferential section of the coupling receptacle attacked, in particular by the above-mentioned closed peripheral portion which partially surrounds the coupling receptacle.
- the closed peripheral section can, for example, have at least essentially a U-shape or C-shape, which is narrowed in the longitudinal direction towards the end of the locking bar.
- Such a reaching behind the coupling section of the anchoring element can take place in particular in addition to the partial circumferential gripping by a closed peripheral section of the coupling receptacle, so that the coupling section not only in the radial direction with the exception of a defined narrow angular range, but also in the axial direction against removal from the coupling receptacle is blocked.
- the coupling section of the anchoring element and the coupling receptacle of the first end section of the locking bar are preferably matched to one another with regard to their respective dimensions, in particular with regard to the dimensions of the circumferential widening and the closed circumferential section mentioned, such that the coupling section accommodated in the coupling receptacle is at least essentially only a single translational one Has degree of freedom.
- This translational degree of freedom can then correspond exactly to the direction in which the locking bar is to be displaced so that the coupling section can pass through the open peripheral section from the coupling receptacle. In particular, this can be a radial offset to the longitudinal axis of the locking bar.
- the coupling section In the axial direction, the coupling section is limited on the one hand by the engagement behind it and on the other hand can be limited in the opposite direction by the axial extent of the coupling receptacle, so that the coupling section is then axially fixed in the coupling receptacle.
- the coupling section accommodated in the coupling receptacle can also have a degree of freedom of rotation, for example around the longitudinal axis of the locking bar.
- the locking bar can be blocked against such rotation by the fact that it rests on the wing with one side face.
- such a rotation can also be blocked in a form-fitting manner by the shape of the coupling receptacle and the coupling section.
- the securing device comprises adjustable locking means which are designed to lock the coupling section of the anchoring element against exiting from the coupling receptacle of the first end section, depending on the position of the locking means, in the coupling state of the securing device.
- the locking means can thus be suitable for locking the last translational degree of freedom of the coupling section of the anchoring element in the coupling receptacle of the first end section of the locking bar, so that the coupling section is caught in the coupling receptacle essentially without play.
- the coupling section in the coupling receptacle is preferably locked in a form-fitting manner.
- the blocking means can engage behind the coupling section in particular against the direction of this degree of freedom in order to completely block the coupling section in the coupling receptacle.
- the locking means are adjustable, it being dependent on the respective position of the locking means whether or not they block the coupling portion accommodated in the coupling receptacle from escaping from the coupling receptacle.
- the locking of the coupling section in the coupling receptacle can in principle be released.
- a blocking element of the blocking means engaging behind the coupling section can be pushed back into a position in which the blocking means release the coupling section for exiting the coupling receptacle.
- the locking element can be moved into a position blocking the coupling section in the coupling receptacle, it preferably being automatically moved into this blocking position, for example due to a preload.
- not only the locking element, but also all the loose parts of the locking device can be spring-biased in order to ensure jam-free handling.
- the coupling section can snap into the coupling receptacle, so that it is advantageously automatically held in the coupling receptacle by the latching action after the coupling receptacle has been reached. It may still be possible to remove the coupling section from the coupling receptacle, in particular against an insurmountable resistance of the locking means and in this respect snapping out.
- the locking means thus help to stabilize the coupling state of the securing device, in which the locking bar is coupled to the anchoring element by engagement of the coupling section of the anchoring element in the coupling receptacle of the first end section. In this way, a reliable hold of the locking bar arranged transversely in front of the closed wing to be secured can be achieved even in the still unsealed coupling state.
- the locking means comprise an engagement recess formed on the coupling section of the anchoring element and a movable recess on the first end section of the locking bar Locking element which is designed to engage the engagement recess in order to lock the coupling section against escaping from the coupling receptacle of the first end section.
- the locking element can be designed as a solid ball, in particular made of hard metal.
- a spherical shape has the advantage that it has a high stability, while the round surface can also contribute to the locking element being easily pushed back into or out of the coupling receptacle when the coupling section is inserted or removed.
- the locking element can also have a different shape, in particular a shape by the engagement of which in the engagement recess, the locking bar can be locked against rotation about its longitudinal axis.
- the engagement recess can be designed as an internal hexagon, while the locking element has an external hexagon shape.
- the engagement recess is preferably formed in an end face of the coupling section of the anchoring element, which faces in the direction in which the coupling section protrudes.
- the coupling section is thus particularly reliably locked in a form-fitting manner by the engagement of the locking element in the end face.
- the anchoring element comprises a DIN screw
- the screw head-side part of which forms the coupling section such an engagement recess on the end face can also be formed by a screw head drive, which is advantageously provided anyway for the engagement of a screwdriver.
- the screw head can be designed in accordance with DIN EN ISO 4762 or in any case have an internal hexagon that can act as an engagement recess into which the respective locking element, which does not necessarily have to be exactly complementary, can engage for locking.
- the locking device is designed to block the locking means for locking the first end section of the locking bar on the anchoring element in a position in which they block the coupling section of the anchoring element against escaping from the coupling receptacle of the first end section. Since the locking means are displaceable and it depends on their respective position whether they lock the coupling section in the coupling receptacle, it is expedient for reliably locking the first end section of the locking bar to the anchoring element to block the locking means in the locking position as required.
- the locking device can advantageously be used, the actuation of which can block the blocking means or the blocking can be released again.
- the locking device is designed so that the release of the blockage to release the locking means (and thus also to release the coupling section that is otherwise caught in the coupling receptacle) requires a locking secret, for example a code or a key.
- a locking secret for example a code or a key.
- the lock is also secured against unlocking if the locking device is accessible to an unauthorized person, for example by breaking a window.
- the locking device can be designed to lock the first end section of the locking bar on the anchoring element to block the locking element engaging in the engagement recess of the anchoring element against backing away in the direction of the locking bar and / or along the longitudinal axis of the locking bar.
- the locking device comprises a blocking body in which a locking cylinder is received and which, depending on a locking state of the locking cylinder, transversely to the mobility of the locking element between a locking position in which it holds the locking element for locking the first end section of the locking bar on the anchoring element blocked in a locking position, and a release position is adjustable in which it does not block the locking element.
- the said locking state preferably depends on whether the locking cylinder is actuated with a key assigned to the locking cylinder.
- the use of the correct key can be a prerequisite both for moving the blocking body into the locking position and for moving the blocking body into the release position.
- the blocking body can also be moved into the locking position without a key, but can only be moved from the locking position into the release position by means of the assigned key.
- the blocking body can be biased into the release position, so that on the one hand it is prevented from reaching the locking position without actuation, and on the other hand it is automatically moved from the locking position to the release position by actuating the locking cylinder by means of the assigned key.
- the blocking body protrudes from the locking bar transversely to the longitudinal axis of the locking bar in the release position and is displaced into the locking bar in the locking position, in particular is flush with a side surface of the locking bar.
- the respective position of the blocking body and thus the security status of the security device are then easy for a user to recognize, even from a certain distance. If the locking device is in the coupled state, that is to say the locking bar is connected to the anchoring element via its first end section, the locking can then be carried out simply by pressing the blocking body into the locking bar, for which purpose advantageously no key is required.
- the locking bar and the anchoring element are designed so that the locking bar in the coupled state the securing device is substantially flat against the reveal of the window or door.
- the locking bar preferably does not engage in the reveal, but only extends to the reveal.
- the locking bar in the coupling state, can rest on the reveal with an end face of its first end section.
- an opposite second end section of the locking days can advantageously lie flat against an opposite side of the reveal in a corresponding manner.
- the locking bar rests flatly in particular in that it is arranged parallel to the reveal with a surface aligned with the reveal, with no or only a slight gap remaining between the surface and the reveal.
- the locking bar then connects, preferably at both ends, at least essentially flush with the reveal.
- the locking bar arranged in front of the wing to be secured can already be axially fixed in the direction of its longitudinal axis. Furthermore, it contributes to the reliable attachment of the locking bar in front of the window to be secured if a large overlap of the locking bar with the respective anchoring element is achieved by the interaction of the respective coupling receptacle and the respective coupling section accommodated therein.
- the first end section of the locking bar is positively attached to the anchoring element in all spatial directions. In this way, the play of the locking bar attached in front of the wing can be minimized.
- the form-fitting fixing can also be present in the unlocked coupling state, in which the locking bar can still be detached from the anchoring element, but can nevertheless be supported in a form-fitting manner, even if this form-fitting support can be overcome without the additional locking.
- the anchoring element comprises a bolt-shaped mounting section and a sieve sleeve and is designed to be arranged with the sieve sleeve and the mounting section accommodated therein in a bore in the region of the reveal of the window or door and to be fastened by means of injection mortar.
- the attachment of a locking bar may require exact positioning of the anchoring elements in the reveal.
- the anchoring element can in principle simply be screwed in or dowelled, the respective level of security depending, among other things, on the overlap of the anchoring element with the reveal or the wall area.
- a particularly advantageous fastening possibility results from the use of a sieve sleeve, through which an exact positioning of the anchoring element can be achieved comparatively easily in connection with injection mortar.
- the bolt-shaped mounting section of the anchoring element can be inserted into the sieve sleeve so that it is surrounded by the injection mortar.
- the mounting section and the coupling section of the anchoring element connected to it can still be moved.
- the locking bar can be coupled to the anchoring element, as a result of which the still movable coupling section assumes a position which is correctly aligned for the coupling to the locking bar. In this position, the anchoring element is then fixed by the hardening injection mortar.
- the assembly section mentioned can in particular be at least a part of the shaft of a screw, for example a cylinder head screw, the coupling section being able to be formed by the screw head and, if appropriate, a remaining part of the shaft.
- the anchoring element is advantageously mounted, at least partially engaging in the reveal, for example screwed or dowelled, for example as described above using a sieve sleeve.
- a bore which may have to be provided for receiving a part of the anchoring element in the reveal, is preferably formed parallel to the wing plane and perpendicular to the surface of the reveal in the reveal.
- a particularly compact anchoring element is obtained if the anchoring element only protrudes with the coupling section out of the hole beyond the reveal and the coupling section extends along the axis of the hole.
- the hole in the reveal for fastening the anchoring element can therefore be provided in particular in the extension of the locking bar arranged in front of the wing to be secured. Providing a hole there can be structurally problematic under certain circumstances. For example, in the area in which the locking bar is to be attachable to the reveal with its first end section, insulation can be provided which would be impaired by a bore.
- the securing device comprises at least one anchoring element which has a coupling section for coupling the first end section of the locking bar to the anchoring element and at least one mounting section which is designed to be in a bore in the region of the reveal of the window or the door to be arranged and fastened, the coupling section and the mounting section being offset parallel to one another and aligned.
- Such an offset between the mounting section to be inserted into the bore and the coupling section that can be coupled to the first end section of the locking bar can be achieved, for example, in that the anchoring element has a base plate, from which the coupling section on one flat side and the mounting section on its other flat side of each extend from different starting points parallel to each other and preferably perpendicular to the base plate.
- the anchoring element has a base plate, from which the coupling section on one flat side and the mounting section on its other flat side of each extend from different starting points parallel to each other and preferably perpendicular to the base plate.
- it can be advantageous to increase the stability of the anchoring if a respective anchoring element has several, in particular identical, mounting sections.
- the securing device comprises at least two anchoring elements, each with a coupling section, the locking bar having a second end section opposite the first end section with respect to the longitudinal axis of the locking bar with a coupling receptacle, which is designed to be detachably coupled to a respective one of the anchoring elements by engaging in the coupling state of the securing device, the coupling section of the respective anchoring element in the coupling receptacle of the second end section of the locking bar.
- the locking bar can be coupled to a respective anchoring element at both ends of its longitudinal extent in order to be reliably held on both sides in the coupling state, arranged transversely in front of the closed wing to be secured.
- the anchoring elements are expediently permanently permanently mounted on opposite sides of the wing.
- the first and the second end section of the locking bar can be designed differently. However, they are preferably designed to be functionally corresponding to one another at least insofar as they can each be coupled to any respective anchoring element. In other words, both the first and the second end section of the locking bar can optionally be coupled to one or to the other of the two anchoring elements. When attaching the locking bar, it is therefore not necessary to take care to correctly align the locking bar with respect to its end sections.
- the two anchoring elements are preferably of identical design, at least with regard to the design of their respective coupling section.
- they can be of identical construction, which simplifies the manufacture of the anchoring elements.
- the securing device can also comprise various anchoring elements, which are then advantageously compatible with both end sections of the locking bar, in particular because of the similarity of their coupling sections.
- Various anchoring elements can be provided, for example, if an anchoring of the anchoring element as described above is required on one side of the wing, but not on the other side of the wing, or if e.g.
- a sash borders on the reveal on one side, but on the other side it borders on a central web between this and another sash, so that a special anchoring element must be used on this central web, which is perpendicular to the direction in which Coupling section protrudes, is to be assembled.
- the coupling receptacle of the second end section of the locking bar is designed to be placed essentially along the longitudinal axis of the locking bar on the coupling section of the respective anchoring element, with the coupling section of the respective anchoring element preferably being separated from the coupling receptacle of the second end section in the coupling state of the securing device is fully encompassed.
- the coupling section of the anchoring element to be coupled arrives in the coupling receptacle formed on the second end section in at least substantially the axial direction with respect to the longitudinal axis of the locking bar.
- the coupling of the second end section to a respective anchoring element thus differs in particular from the coupling of the first end section described above as a possible embodiment with a respective anchoring element, which does not take place axially, but rather by displacing the locking bar transversely to the longitudinal axis.
- the locking bar can, for example, first be aligned somewhat obliquely to the wing plane along its longitudinal axis with its second end section, and then pivoted toward the wing until it lies parallel to the wing and in particular completely spans the reveal. This pivoting in then also enables the coupling of the first end section to the other anchoring element on the opposite side of the wing.
- the coupling sections are preferably designed such that when the second end section is slipped onto an anchoring element, a degree of freedom of movement remains for the locking bar, so that the first end section can be pushed laterally onto the coupling section of the other anchoring element by pivoting in from a respective direction.
- At least the coupling section, which cooperates with the first end section also preferably has a locking geometry, in particular the engagement recess described above, e.g. in the form of a hexagon hole.
- the coupling section can advantageously also be guided axially out of the coupling receptacle again.
- the locking bar is blocked from being released from the respective anchoring element.
- the locking device of the locking bar advantageously does not also have to interact with the second end section in order to also lock its coupling to the respective anchoring element. Rather, it can be sufficient, by means of the locking device, only that which is received in the coupling receptacle of the first end section To block the coupling section of the respective anchoring element against escaping.
- the locking bar can already be fixed so that it cannot move axially, so that the coupling section of the respective anchoring element cannot emerge from the coupling receptacle at the second end section, since this would only be possible by axially displacing the locking bar.
- the locking device only has to cooperate with the first end section and that no further locking device has to be provided for the second end section enables a simple length adjustment of the locking bar, which has, for example, an elongated base body, at the ends of which the first end section with the locking device and on the other hand the second end section are each arranged as separate structural units.
- the base body can then simply be cut to length and the two end sections can then be connected to the base body. Tolerances in the length of the base body, which result from the cutting to length, can in turn be compensated for, for example, by mounting the respective anchoring elements using injection mortar.
- the locking bar in turn has a second end section opposite the first end section with respect to the longitudinal axis of the locking bar.
- the second end section has a coupling section which protrudes in the direction pointing away from the first end section and is designed, in the coupling state, of the securing device into a on one side, preferably underside, of the window or the Intervening door trained coupling receptacle.
- the coupling of the second end section of the locking bar to a respective anchoring element takes place the other way round than it is is the case with the first end section.
- the second end section has a projecting coupling section, which can be formed, for example, by the screw head of a screw screwed into the second end section.
- the locking bar comprises a base body, which is preferably at least partially hollow, the first end section and optionally the second end section of the locking bar being formed by end elements which are formed separately from the base body and can be placed on the base body.
- the base body can in particular be tubular and can comprise, for example, stainless steel or another solid and advantageously corrosion-resistant metal as the material.
- the placement of the end elements is not limited to the fact that the end elements can only be arranged on the base body from the outside. Rather, the end elements, especially with a hollow design of the base body, can also be at least partially inserted into the base body, for example by inserting it into the ends of the base body.
- the end elements preferably encompass end edges of the base body.
- the end elements can, in particular, cover cut edges that can arise at least at one end due to the cutting of the base body. This not only improves the safety against injuries from the possibly sharp cut edges, but also oblique or unclean cuts can be covered and compensated in this way.
- the end elements overlap with the base body axially by at least about 3 cm, preferably at least about 5 cm, in each case in the state placed on the base body or inserted into the base body.
- the locking bar is designed to lie flat with a side surface parallel to the longitudinal axis of the locking bar on the casement of the casement of the window or the door.
- the mentioned side surface of the locking bar is in particular a side surface of the basic body of the locking bar described above.
- an assembly slightly spaced from the sash can also be expedient, for example in order to secure the sash against complete opening, but to permit tilting opening, for example in order to be able to ventilate without having to remove the locking bar.
- a particularly reliable securing of the wing results, however, if the locking bar rests flatly directly with its side face on the wing, since this blocks any movement of the wing out of the wing plane.
- the safety device is therefore preferably designed to be suitable for such an immediate arrangement.
- the locking bar can have, for example, a polygonal, in particular rectangular, preferably square, cross-section, which not only contributes to the bending stiffness of the locking bar, but also forms a side surface is, which can advantageously extend substantially over the entire length of the locking bar and is thus available for a flat application to the wing.
- the securing device comprises at least two, preferably identical, locking bars and at least one anchoring element, which is designed to be mounted in a direction perpendicular to the sash plane of the closed sash of the window or door, and for releasable coupling with a respective end section of the two locking rods has two, preferably of identical design, coupling sections which, in the assembled state of the anchoring element, project parallel to the wing plane in the opposite direction.
- an anchoring element can be coupled to two locking bars at the same time.
- Such an anchoring element is therefore particularly suitable as an intermediate piece between two locking bars aligned in parallel, in particular in alignment.
- the anchoring element is designed to be mounted perpendicular to the sash plane, that is to say generally perpendicular to the locking bars resting on the sash.
- This makes it possible to mount the anchoring element on a central web between two wings of a multi-wing window or a multi-wing door.
- the anchoring element can have, for example, an assembly section, in particular a pin-shaped one, which can be screwed or dowelled into the central web.
- Such an anchoring element can not only be used as an intermediate anchoring between two locking bars. Because it is not necessary to use both coupling sections of such an anchoring element for coupling to a respective locking bar. Because the assembly is carried out perpendicular to the direction in which the coupling sections are aligned, the anchoring element can also be used instead on to provide a coupling section for a single locking bar on a wall parallel to the sash level of the sash to be secured, in which the window or door is located (wall-mounted installation). The attachment is then expediently close to the window or door, that is, still in the area of the reveal of the window or door, but not in the surface of the reveal itself, which is oriented perpendicular to the sash plane, but in the surrounding wall. It may be necessary, for example, to mount an anchoring element in the surrounding wall instead of in the reveal if the reveal is too narrow for assembly.
- the securing device according to the invention can also be used to secure the sash of a sliding door or a sliding window, even if this sash does not have to make any movement perpendicular to its sash plane for opening.
- the locking bar is then advantageously not installed transversely in front of the wing to be secured, but between the narrow side of the wing pointing in the opening direction and the reveal, to which the wing is pushed when opening.
- the locking bar is then axially loaded and blocks the opening movement.
- coupling can take place in the same way as described above between an anchoring element mounted in the region of the reveal and the first end section of the locking bar.
- the second end section can also be coupled to an anchoring element on the said narrow side of the wing.
- the locking bar 13 reliably secures the wing 15 even under the action of force, it is coupled at the two ends of its longitudinal extension to an anchoring element 23, which in turn is connected to a mounting section 25 (cf. Fig. 2 ) engages deep in the reveal 27 of the window 17 and is thereby permanently mounted on the window 17.
- the reveal 27 is in Fig. 1 shown transparently so that the engagement of the mounting section 25 of the anchoring element 23 in the reveal 27 can be seen.
- the coupling section 29 serves for releasable and optionally lockable coupling to a respective end section 31, 33 of the locking bar 13, so that the locking bar 13 can be stably attached in front of the wing 15 via the anchoring elements 23, but can also be released again.
- the anchoring element 23 comprises a cylinder head screw 35, the screw shaft of which is received almost completely in a sieve sleeve 37.
- the remaining screw shaft and the sieve sleeve 37 are designed to use injection mortar in a respective bore in to be attached to the reveal 27, and in this respect form the mounting section 25 of the anchoring element 23.
- the cylinder head screw 35 can also be screwed into the reveal 27 via the thread on its screw shaft, so that under certain circumstances the sieve sleeve of the anchoring element 23 remains unused.
- the cylinder head screw 35 which is designed in particular in accordance with DIN EN ISO 4762, has an engagement recess 41 in the form of a hexagon socket in the end face of its cylinder head. Structures are formed on the anchoring element 23 by the circumferential widening 39 and the engaging recess 41, which enable the coupling section 29 to be positively gripped behind in many different spatial directions, namely by engaging in the engaging recess in all radial directions and by engaging behind the circumferential widening 39 in the axial direction on the direction in which the Coupling section 29 protrudes and which in the embodiment shown corresponds to a longitudinal and symmetrical axis of the anchoring element 23).
- Fig. 3 the same anchoring element 23 is shown together with the first end section 31 of the locking bar 13.
- Fig. 5 a structurally identical anchoring element 23 together with the opposite second end section 33 of the locking bar 13.
- the end sections 31, 33 are essentially formed by respective end elements 43, 45 which are fitted onto a respective end of the base body 19 of the locking bar 13 by a precise insertion.
- the end elements 43, 45 are each shown separately from the base body 13. When the end elements 43, 45 are placed on the base body 19, they surround the respective peripheral edge of the base body 19 in a collar-like manner, which under certain circumstances can be sharp and irregular by cutting the base body 19 to a length adapted to the window width.
- the locking bar 13 in the coupling state, in which it is coupled to the permanently attached anchoring elements 23, can advantageously lie flat against the reveal 27 with the essentially flat end faces 47 of the end elements 43, 45 instead of with the edges of its base body 19, but still a small gap can remain.
- the end sections 31, 33 each have a coupling receptacle 49, into which the coupling section 29 of the respective anchoring element 23 can be received.
- the coupling receptacle 49 of the first end section 31 is delimited in the radial direction (with respect to the longitudinal axis L of the locking bar 13) by a closed peripheral section 51 which forms a U-shaped wall through which the coupling section 29 of an anchoring element 23 cannot be passed.
- the radial region which is permeable in the radial direction forms an open peripheral section 53 of the coupling receptacle 49.
- the closed peripheral section 51 narrows towards the end face 47, whereby a stop edge 55 is formed, which engages behind the circumferential widening 39 of the coupling section 29 received in the coupling receptacle 49, so that the coupling section 29 can neither axially penetrate into the coupling receptacle 49 nor emerge from the coupling receptacle 49.
- the first end section 31 of the locking bar 13 can therefore be placed on the coupling section 29 of the respective anchoring element 23 only in the radial direction with respect to the longitudinal axis L of the locking bar 13 and perpendicular to the extent of the coupling section 29.
- a locking device 57 is also provided, by means of which the first end section 31 can be locked to the respective anchoring element 23.
- the locking device comprises a blocking body 59, in which a locking cylinder 61 is received and which is between a locking position ( Fig. 3 , below) and one in Fig. 3 additionally shown release position ( Fig. 3 , above) is adjustable.
- the blocking body 59 can be pressed from the release position into the base body 19 and the end element 43 into the locking position.
- actuation by means of a key assigned to the locking cylinder 61 required.
- Coupling receptacle 49 shown of the second end section 33 is completely enclosed in the radial direction and has no narrowing in the axial direction. Therefore, the coupling section 29 of the respective anchoring element 23 can be inserted axially, but not radially into the coupling receptacle 49 of the second end section 33 of the locking bar 13 or removed from the coupling receptacle 49.
- the trough 63 formed in a radial direction is not sufficient for the coupling section 29 to be passed through, but is for the coupling with the in FIG Fig. 10 shown anchoring element 23, as will be explained below.
- no locking device 57 is provided on the second end section 33, unlike on the first end section 31 of the locking bar 13.
- the locking rod 13 can thus first be placed axially with its second end section 33 onto one of the anchoring elements 23 mounted in the reveal 27 of the window 17.
- the locking rod 13, which is already coupled on one side, can then be placed radially on the other anchoring element 23 by pivoting it in with its first end section 31, which is done, for example, from the front, but preferably (as shown) from above.
- the 7 and 8 show sectional views of the first end portion 31 of the locking bar 13 and an associated anchoring element 23, wherein the base body 19 of the locking bar 13 is not shown.
- the sectional plane which essentially corresponds to a mirror plane of the securing device 11, runs vertically and is aligned parallel to the longitudinal axis L of the locking bar 13.
- the 7 and 8 differ from each other essentially only in that Fig. 7 shows the coupling state in which the coupling section 29 of the anchoring element 23 is received in the coupling receptacle 49 of the first end section 31 of the locking rod 13 formed in the end element 43
- Fig. 8 shows the locking bar 13 detached from the anchoring element 23, but in a position from which it can be placed on the anchoring element 23 by moving it downward.
- a blocking element 65 designed as a ball can be seen that is axially movably mounted in the end element 43. From the in the 7 and 8 shown blocking position, the ball 65 can be pushed axially against the bias of a spring 67 axially from the coupling receptacle 49.
- the spring 67 is shown in the figures in a relaxed state and therefore overlaps other elements of the locking bar 13, in particular also the ball 65. In fact, the spring is of course compressed in the assembled locking rod 13.
- An axially movable driver 69 is effective between the ball 65 and the blocking body 59.
- the ball prevents insertion or removal of the coupling section 29 of the anchoring element 23 into or out of the coupling receptacle 49.
- the blocking body 59 (as in FIG Fig. 3 shown above) assumes its release position, are pushed together with the driver 69 against the bias of the spring 67 from the coupling receptacle 49.
- the coupling section 29 can be made from the in Fig. 8 position shown are inserted into the coupling receptacle 49.
- the ball 65 which is actuated by the spring 67 via the driver 69, can be set back into the blocking position, in which it then engages in the engagement recess 41 of the coupling section 29 and in this way blocks the coupling section 29 from escaping from the coupling receptacle 49.
- the blocking body 59 If the blocking body 59 is then moved into the locking position shown, it blocks the driver 69 at its end opposite the ball 65, so that the ball 65 can no longer be pushed back and is also blocked by the blocking body 59 in the blocking position. As a result, the locking bar 13 is then locked on the anchoring element 23, since the coupling section 29 can no longer leave the coupling receptacle 49 and the locking bar 13 can therefore not be released from the anchoring element 23 without first releasing the locking device via the locking device 57.
- the driver 69 In the event that the ball 65 has not yet fully reached its blocking position when the blocking body 59 is pressed in, the driver 69 a run-on slope 71, against which the blocking body 59 then starts, whereby the movement of the blocking body 59 is derived to axially move the driver 69 and the ball 65 into the blocking position. Furthermore, the blocking body 59 is biased into the release position by a further spring 73, so that in order to unlock the locking rod 13, only the assigned key in the locking cylinder 61 of the locking device 57 has to be turned and the blocking body 57 is then automatically put into the release position, whereby the ball 65 is released for moving from its blocking position.
- Fig. 9 and 11 show alternative embodiments of the security device 11 according to the invention, which are suitable for double-leaf windows 17 '.
- the securing device 11 comprises a two-part locking bar 13 which comprises two individual partial locking bars 13.1, 13.2.
- the individual partial locking bars 13.1, 13.2 can each be constructed essentially identically to a locking bar 13 designed for a single-wing window 17 of a corresponding width.
- An additional anchoring element 23 ' is provided between the two partial locking bars 13.1, 13.2 Fig. 10 is shown separately.
- the mounting section 25 of this anchoring element 23 ′ essentially corresponds to that of the in FIG Fig. 2 Anchoring element 23 shown, in contrast to which the in Fig.
- Anchoring element 23 ' has two coupling sections 29 which protrude in the opposite direction and are of the same design, that is to say in particular each have a circumferential widening 39 and an end engagement recess 41, each with corresponding dimensions. They are also two coupling sections 29 aligned perpendicular to the mounting section 25, so that the anchoring element 23 'can be screwed or dowelled into the central web 75 between the two wings 15 of the window 17' and the coupling sections 29 for coupling the locking bars 13.1, 13.2 then parallel to the wing plane of the closed one Wing 15 are aligned.
- the anchoring element 23 ' is mounted such that an intermediate section 77 remains between the mounting section 25 and the coupling sections 29. So that the two partial locking bars 13.1, 13.2 connect as flush as possible when they are coupled to the anchoring element 23 ', a trough 63 is formed on the edge of the coupling receptacle 49 of the respective second end section 33 of the two locking bars 13.1, 13.2 in the end element 45 (cf. 5 and 6 ).
- FIG. 11 An additional anchoring point is achieved by the provision of a support element 79 which can be attached to the central web 75 and which in Fig. 12 is shown separately.
- the support element 79 is not designed for coupling to the locking bar 13. Therefore, the locking bar 13 cannot be divided into two partial locking bars, but must extend beyond the support element 79. Unlike in the embodiment according to Fig. 9 it is therefore not possible in this embodiment to secure only one wing 15.
- the support element 79 is essentially hook-shaped, so that the locking bar 13 can simply be inserted into the support element 79 and is then supported by resting on the support element 79 without being coupled to it. However, the support element 79 has a short rear grip 81 at its free end.
- Such a configuration has the advantage that the locking bar 13 is pushed under the rear grip 81 when force is applied in the opening direction of the respective wing 15 and thereby in the direction of removing the locking bar 13 from the support element 79 (at the illustrated orientation of the support element 79: upward) is retained by the rear grip 81.
- the 13 and 14 is an alternative to the 5 and 6 trained second end portion 33 of the locking bar 13 shown.
- the end element 45 of this embodiment and that of the embodiment according to FIGS 5 and 6 be essentially identical.
- a nut 83 is inserted into the end of the end element 45 located inside the locking rod 13, into which a cylinder head screw 35, in particular in accordance with DIN EN ISO 4762, is screwed from the opposite end of the end element 45 (cf. in particular the sectional view of the Fig. 14 ).
- a screw sleeve 85 is also provided, which surrounds the screw shaft below the screw head.
- the locking bar 13 with the second end section 33 can be inserted into a bore, for example on the bottom of a French window become. If the locking bar with the coupling section 29 is inserted into the bore at its second end section 33, then there is still a sufficient degree of freedom of movement for pivoting the locking bar 13, so that the coupling of the first end section 31 subsequently, as otherwise, by laterally receiving a coupling section 29 Anchoring element 23 can take place in the coupling receptacle 49 of the first end section 31.
- FIG. 15 shows an anchoring element 23 "which, as an alternative to that in FIG Fig. 2 Anchoring element 23 shown can be used.
- the anchoring element 23 ′′ has a base plate 87, from which a coupling section 29 extends on one flat side of the base plate 87, which essentially corresponds to the coupling section 29 of FIG Fig. 2 Anchoring element 23 shown corresponds.
- Two bolt-shaped extensions extend from the opposite flat side of the base plate 87, each of which forms a mounting section 25 ′ of the anchoring element 23 ′′ and in this respect is designed to engage in the reveal 27 or the surrounding wall in the region of the reveal 27 of a window 17 or a door
- the anchoring element 23 ′′ not only has two mounting sections 25 ′, but the mounting sections 25 ′ are also offset parallel to the coupling section 29. Due to this offset, the coupling section 29 can also be mounted at locations where direct attachment is not possible, for example if insulation is provided there which would be damaged or offer insufficient support for installation.
- FIG. 16 An exemplary wall bracket 89 of the securing device 11 according to the invention is shown.
- This wall bracket 89 has a mounting section 25 ′′, which is in particular designed to be dowelled into a wall.
- the wall bracket 89 has a coupling section 29 ′ which is at least similar to the coupling section 29 of the above-described embodiments in that it mates with the coupling receptacle 49 of the first end section 31 of the locking bar 13.
- the coupling section 29 ' is aligned such that when the wall bracket 89 is fastened to a wall, the locking bar 13 transversely to its longitudinal axis L with its first end section 31 onto the coupling section 29' of the wall bracket 89 can be placed so that the locking bar 13 is held hanging from the wall bracket 89.
- the wall bracket 89 has a circumferential widening 39 and an engagement recess 41. This makes it possible to lock the locking bar 13 on the wall bracket 89 so that the locking bar 13 cannot be removed from the wall bracket 89 without a key. This can be useful in public buildings, for example, where, for example, to ensure escape opportunities, it must be prevented that a window or door is locked inadmissibly.

Description
Die vorliegende Erfindung betrifft eine Sicherungsvorrichtung mit einer Riegelstange, die nach Bedarf quer vor dem geschlossenen Flügel eines Fensters oder einer Tür anordenbar ist, um den Flügel gegen ein Öffnen zu sichern. Zwar weist in der Regel der zur Lagerung des Flügels am Rahmen vorgesehene Beschlag bereits eine Verriegelungsfunktion auf. Die Sicherheit der Verriegelung, insbesondere gegen ein gewaltsames Aufbrechen oder Aufstemmen, wie etwa bei einem Einbruch, kann aber durch das zusätzliche Vorsehen einer Sicherungsvorrichtung an dem Fenster oder der Tür noch wesentlich verbessert werden.The present invention relates to a securing device with a locking bar, which can be arranged as required transversely in front of the closed wing of a window or door to secure the wing against opening. As a rule, the fitting provided for mounting the sash on the frame already has a locking function. The security of the lock, in particular against violent breaking open or prying open, such as in the event of a break-in, can, however, be significantly improved by the additional provision of a security device on the window or door.
Sicherungsvorrichtungen können beispielsweise zusätzliche Verbindungspunkte zwischen dem Flügel und dem Rahmen des Fensters oder der Tür bereitstellen. Mit jedem zusätzlichen Verbindungspunkt muss dann mehr Kraft aufgewandt werden, um das Fenster oder die Tür aufzubrechen, so dass ein Einbruch erschwert wird. Derartige Sicherungsvorrichtungen müssen aber in der Regel einerseits an dem Rahmen und andererseits an dem Flügel montiert werden, was zu Beschädigungen des Rahmens und insbesondere des Flügels führen kann. Zudem kann für Mieter das Einverständnis des Vermieters zu einem solchen baulichen Eingriff in das Fenster oder die Tür erforderlich sein, zumal sich an dem Flügel befestigte Sicherungsvorrichtungen oftmals nicht zufriedenstellend zurückbauen lassen.For example, securing devices can provide additional connection points between the sash and the frame of the window or door. With each additional connection point, more force has to be used to break the window or door, making it difficult to break in. However, such safety devices generally have to be mounted on the frame on the one hand and on the wing on the other hand, which can damage the frame and in particular the wing. In addition, the landlord's consent to such a structural intervention in the window or door may be required for tenants, especially since securing devices attached to the sash can often not be removed satisfactorily.
Diese Schwierigkeiten lassen sich durch Verwendung einer Riegelstange vermeiden, die zum Sichern des geschlossenen Flügels derart quer vor dem Flügel fest angebracht wird, dass sie einer Öffnungsbewegung des Flügels im Wege steht. Beispielsweise kann die Riegelstange horizontal oder vertikal angebracht werden. Grundsätzlich kann sie aber in jeder nach den bauseitigen Gegebenheiten für ein Sichern des geschlossenen Flügels geeigneten Ausrichtung quer vor dem Flügel angebracht werden. Selbst wenn dann die übliche Verriegelungsfunktion des Fenster- oder Türbeschlags überwunden wird, bleibt der Flügel durch die Riegelstange gegen ein Öffnen gesichert, so dass ein Einsteigen durch das Fenster oder die Tür verhindert werden kann.These difficulties can be avoided by using a locking bar which is fixed transversely in front of the wing in order to secure the closed wing in such a way that it stands in the way of an opening movement of the wing. For example, the locking bar can be attached horizontally or vertically. In principle, however, it can be installed transversely in front of the sash in any orientation that is suitable for securing the closed sash on site. Even if the usual locking function of the window or door fitting is then overcome, the sash remains secured against opening by the locking bar, so that boarding through the window or door can be prevented.
Voraussetzung für die Zuverlässigkeit einer solchen Sicherungsvorrichtung ist, dass die Riegelstange stabil verankert ist. Dazu braucht die Riegelstange vorteilhafterweise nicht am Flügel oder am Rahmen des Fensters oder der Tür verankert zu werden. Denn zur Befestigung der Riegelstange quer vor dem geschlossenen Fenster kann die Riegelstange stattdessen an der Laibung bzw. im angrenzenden Wandbereich des Fensters oder der Tür, also typischerweise in massivem Mauerwerk oder Beton, verankert werden. Das hat nicht nur den Vorteil, dass das Fenster oder die Tür, insbesondere der Flügel des Fensters oder der Tür, unbeschädigt bleibt, sondern auch, dass auf diese Weise besonders hohe Kräfte abgestützt werden können.The prerequisite for the reliability of such a securing device is that the locking bar is stably anchored. For this purpose, the locking bar advantageously does not need to be anchored to the sash or to the frame of the window or door. Because to fasten the locking bar transversely in front of the closed window, the locking bar can instead be anchored to the reveal or in the adjacent wall area of the window or door, i.e. typically in solid masonry or concrete. This not only has the advantage that the window or door, in particular the sash of the window or door, remains undamaged, but also that particularly high forces can be supported in this way.
Eine Möglichkeit, die Riegelstange im Bereich der Laibung des Fensters oder der Tür zu verankern, besteht darin, an zwei entgegengesetzten Seiten des Fensters oder der Tür jeweils eine Bohrung oder sonstige Aussparung in der Laibung vorzusehen, in die die Riegelstange mit einem jeweiligen Ende eingesetzt wird. Eine derartige Befestigung der Riegelstange setzt aber nicht nur voraus, dass die Bohrungen relativ zueinander präzise, insbesondere genau fluchtend, ausgerichtet sind, sondern auch, dass die Riegelstange längenvariabel ist, um zunächst zwischen der Laibung vor dem Flügel positioniert zu werden und anschließend mit ihren beiden Enden in entgegengesetzte Richtungen in eine jeweilige Bohrungen einzugreifen. Die Riegelstange muss dazu beispielsweise nach Art einer Teleskopstange ausgebildet sein oder beidseitig ausfahrbare Riegel aufweisen. Derartige Mechaniken sind aber im ausgezogenen Zustand mechanisch weniger stabil als ein starrer Riegel fester Länge, zudem technisch aufwendig und verursachen daher vergleichsweise hohe Kosten.One way of anchoring the locking bar in the area of the reveal of the window or door is to provide a hole or other recess in the reveal, on each of two opposite sides of the window or door, into which the locking bar is inserted with a respective end , Such a fastening of the locking bar not only requires that the bores are precisely aligned, in particular exactly aligned, but also that the locking bar is variable in length in order to be positioned between the reveal in front of the wing and then with both of them Engage ends in opposite directions in a respective bore. For this purpose, the locking bar must be designed, for example, in the manner of a telescopic bar or have bars that can be extended on both sides. Such mechanisms are mechanically less stable when extended as a rigid bar of fixed length, also technically complex and therefore cause comparatively high costs.
Sicherungsvorrichtungen mit teleskopierbaren Riegelstangen, die axial, d.h. in Richtung ihrer Längserstreckung, in Aufnahmen von an der Laibung eines zu sichernden Fensters oder einer zu sichernden Tür befestigten Verankerungselementen eingreifen, sind beispielsweise aus
Für die Zuverlässigkeit der Sicherungsvorrichtung ist ferner wichtig, dass sie sich einfach und komfortabel verwenden lässt. Denn wenn die Sicherung des Flügels mittels der Sicherungsvorrichtung umständlich ist, führt dies oftmals dazu, dass die Sicherungsvorrichtung nicht konsequent angewandt wird.It is also important for the reliability of the safety device that it can be used easily and comfortably. Because if the securing of the wing by means of the securing device is cumbersome, this often means that the securing device is not used consistently.
Es ist eine Aufgabe der Erfindung, eine Sicherungsvorrichtung der genannten Art zur Sicherung des Flügels eines Fensters oder einer Tür gegen ein Öffnen bereitzustellen, die eine einfache und das Fenster oder die Tür möglichst wenig beeinträchtigende Montage erlaubt, besonders zuverlässigen Schutz bietet und dabei komfortabel zu bedienen ist.It is an object of the invention to provide a securing device of the type mentioned for securing the sash of a window or a door against opening, which permits simple assembly which has as little impairment as possible on the window or the door, offers particularly reliable protection and is easy to operate is.
Die Aufgabe wird gelöst durch eine Sicherungsvorrichtung mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen, der vorliegenden Beschreibung sowie den Figuren.The object is achieved by a securing device with the features of claim 1. Advantageous further developments of the invention result from the subclaims, the present description and the figures.
Die erfindungsgemäße Sicherungsvorrichtung umfasst zumindest ein Verankerungselement, das dazu ausgebildet ist, an einer Seite des Fensters oder der Tür im Bereich einer Laibung des Fensters oder der Tür dauerhaft montiert zu werden. Durch eine Verankerung an der Laibung des Fensters oder an der daran angrenzenden Wand kann die Riegelstange besonders stabil quer vor dem geschlossenen Flügel angeordnet werden. Dabei ist die Riegelstange insbesondere insofern quer vor dem Flügel angeordnet, als sich die Riegelstange entlang ihrer Längsachse von einer Seite des Flügels zur entgegengesetzten Seite erstreckt, wobei die Längsachse zumindest im Wesentlichen parallel zur Flügelebene ausgerichtet ist.The securing device according to the invention comprises at least one anchoring element which is designed to be permanently installed on one side of the window or the door in the region of a reveal of the window or the door. By anchoring to the reveal of the window or to the wall adjacent to it, the locking bar can be arranged particularly stably transversely in front of the closed sash. The locking bar is in particular arranged transversely in front of the wing in that the locking bar extends along its longitudinal axis from one side of the wing to the opposite side, the longitudinal axis being aligned at least substantially parallel to the wing plane.
Dadurch, dass zum Anbringen der Riegelstange ein gesondertes Verankerungselement vorgesehen ist, braucht die Riegelstange nicht direkt mit dem Mauerwerk oder dem Beton zusammenzuwirken, sondern kann mit dem Verankerungselement zusammenwirken, das, wie nachfolgend beschrieben wird, speziell für eine einfache und komfortable und dabei gleichwohl widerstandsfähige Kopplung mit der Riegelstange ausgebildet sein kann. Im Gegensatz zur Riegelstange, die sich für ein reguläres Öffnen des Flügels entfernen, also von dem Verankerungselement lösen lassen muss, ist das Verankerungselement dabei dauerhaft montiert, beispielsweise fest in die Laibung eingelassen, z.B. eingeschraubt, gedübelt oder mittels Injektionsmörtel verankert. Die Fixierung des Verankerungselements im Bereich der Laibung kann auf diese Weise im Hinblick auf eine hohe Festigkeit und Belastbarkeit hin optimiert werden. Eine Injektionsmörtelverankerung weist den zusätzlichen Vorteil auf, dass Montageungenauigkeiten, z.B. infolge verlaufender Bohrer, egalisiert werden können.Due to the fact that a separate anchoring element is provided for attaching the locking bar, the locking bar does not have to interact directly with the masonry or the concrete, but can interact with the anchoring element, which, as described below, is especially designed for a simple and comfortable and yet resistant Coupling can be formed with the locking bar. In contrast to the locking bar, which has to be removed for regular opening of the sash, i.e. must be detachable from the anchoring element, the anchoring element is permanently installed, for example firmly embedded in the reveal, e.g. screwed in, dowelled or anchored using injection mortar. The fixing of the anchoring element in the reveal can be optimized in this way with a view to high strength and resilience. Injection mortar anchoring has the additional advantage that assembly inaccuracies, e.g. due to the running drill, can be equalized.
Zur Kopplung mit der Riegelstange weist das Verankerungselement einen Kopplungsabschnitt auf, der im montierten Zustand des Verankerungselements in Richtung der entgegengesetzten Seite des Fensters oder Tür vorsteht. Bevorzugt steht der Kopplungsabschnitt dabei, insbesondere wenn das Verankerungselement zumindest teilweise in die Laibung eingesetzt ist, über die Laibung hinaus in Richtung der entgegengesetzten Seite des Fensters oder Tür vor. Der Kopplungsabschnitt kann beispielsweise zumindest im Wesentlichen zapfenförmig ausgebildet sein. Vorstehen kann der Kopplungsabschnitt insbesondere insofern, als er sich zwischen einem mit dem übrigen Verankerungselement verbundenen Ende und einem dazu entgegengesetzt ausgerichteten freien Ende erstreckt, so dass der Kopplungsabschnitt, abgesehen von dem verbundenen Ende, eine von dem übrigen Verankerungselement gesonderte Struktur darstellt, die somit speziell zur Ankopplung der Riegelstange dienen kann. Die Richtung, in die der Kopplungsabschnitt vorsteht, wird dabei durch die Lage des freien Endes relativ zu dem verbundenen Ende des Kopplungsabschnitts definiert. Insbesondere kann die Richtung, in die der Kopplungsabschnitt vorsteht, der Ausrichtung einer Längsachse des Kopplungsabschnitts oder einer Symmetrieachse, zu welcher der Kopplungsabschnitt zumindest im Wesentlichen symmetrisch ausgebildet ist, entsprechen.For coupling to the locking bar, the anchoring element has a coupling section which, in the assembled state of the anchoring element, projects in the direction of the opposite side of the window or door. The coupling section preferably protrudes beyond the reveal in the direction of the opposite side of the window or door, in particular if the anchoring element is at least partially inserted into the reveal. The coupling section can, for example, be at least substantially cone-shaped. The coupling section can protrude in particular insofar as it extends between an end connected to the remaining anchoring element and an oppositely oriented free end, so that the coupling section, apart from the connected end, represents a separate structure from the remaining anchoring element, which is therefore special can be used to couple the locking bar. The direction in which the coupling section protrudes is defined by the position of the free end relative to the connected end of the coupling section. In particular, the direction into which the coupling section protrudes correspond to the orientation of a longitudinal axis of the coupling section or an axis of symmetry, to which the coupling section is at least substantially symmetrical.
Die Riegelstange weist erfindungsgemäß eine Schließvorrichtung und zumindest einen ersten Endabschnitt mit einer Kopplungsaufnahme auf, wobei der Endabschnitt dazu ausgebildet ist, mit dem Verankerungselement lösbar gekoppelt zu werden, indem in einem Kopplungszustand der Sicherungsvorrichtung der Kopplungsabschnitt des Verankerungselements in die Kopplungsaufnahme des ersten Endabschnitts der Riegelstange eingreift. Der erste Endabschnitt ist dabei insbesondere an einem von zwei entgegengesetzten Enden der Längserstreckung der Riegelstange ausgebildet, die sich vorzugsweise mit zumindest überwiegend konstantem Querschnitt und zumindest im Wesentlichen geradem Verlauf entlang einer Längsachse erstreckt.According to the invention, the locking bar has a locking device and at least one first end section with a coupling receptacle, the end section being designed to be detachably coupled to the anchoring element by the coupling section of the anchoring element engaging in the coupling receptacle of the first end section of the locking bar in a coupling state of the securing device , The first end section is in particular formed on one of two opposite ends of the longitudinal extension of the locking bar, which preferably extends with an at least predominantly constant cross section and at least essentially a straight course along a longitudinal axis.
Anders als bei einer telekopierbaren Riegelstange oder einer Riegelstange mit an den Enden ausfahrbaren Riegeln braucht also die Riegelstange nicht in die Laibung einzugreifen. Vielmehr greift, gerade umgekehrt, ein im Bereich der Laibung montiertes Verankerungselement mit einem Kopplungsabschnitt in die Riegelstange ein, die dazu an ihrem ersten Endabschnitt eine Kopplungsaufnahme aufweist. Dadurch, dass der vorstehende Kopplungsabschnitt an dem Verankerungselement und die Kopplungsaufnahme an dem ersten Endabschnitt der Riegelstange in geeigneter Weise passend zueinander ausgebildet werden, kann eine einfache und zuverlässige Kopplungsmöglichkeit zur Anbringung der Riegelstange an dem Verankerungselement geschaffen werden. Vorteilhafterweise braucht die Riegelstange für eine solche Kopplung nicht längenvariabel zu sein, so dass sie einen vergleichsweise einfachen und damit konstant stabilen Aufbau aufweisen kann. Um die Länge der Riegelstange an ein jeweiliges Fenster oder eine jeweilige Tür anzupassen, kann die Riegelstange vorzugsweise einfach ablängbar sein. Dazu kann die Riegelstange einen ablängbaren Grundkörper aufweisen, wobei Endabschnitte der Riegelstange, die für Zusammenwirken mit einem jeweiligen Verankerungselement ausgebildet sind, durch von dem Grundkörper separate, aber mit dem Grundkörper verbindbare Endelemente gebildet werden können, wie weiter unten noch erläutert wird. Wenn die Länge der Riegelstange im Wesentlichen dem Abstand zwischen zwei entgegengesetzten Seiten der Laibung entspricht, kann sie bei Nichtbenutzung z.B. vorteilhafterweise einfach auf der Fensterbank eines jeweiligen Fensters abgelegt werden.In contrast to a telescopic locking bar or a locking bar with locking bars that can be extended at the ends, the locking bar does not need to intervene in the reveal. Rather, just the other way round, an anchoring element mounted in the region of the reveal engages with a coupling section in the locking bar, which for this purpose has a coupling receptacle at its first end section. The fact that the projecting coupling section on the anchoring element and the coupling receptacle on the first end section of the locking bar are designed in a suitable manner to match one another, can provide a simple and reliable coupling possibility for attaching the locking bar to the anchoring element. Advantageously, the locking bar does not have to be variable in length for such a coupling, so that it can have a comparatively simple and thus constantly stable structure. In order to adapt the length of the locking bar to a respective window or door, the locking bar can preferably be easily cut to length. For this purpose, the locking bar can have a body that can be cut to length, with end sections the locking bar, which are designed for cooperation with a respective anchoring element, can be formed by end elements which are separate from the base body but can be connected to the base body, as will be explained further below. If the length of the locking bar essentially corresponds to the distance between two opposite sides of the reveal, it can advantageously be simply placed on the window sill of a particular window when not in use.
In dem genannten Kopplungszustand der Sicherungsvorrichtung sind durch das Eingreifen des Kopplungsabschnitts des Verankerungselements in die Kopplungsaufnahme des ersten Endabschnitts der Riegelstange die Riegelstange und das Verankerungselement miteinander gekoppelt, allerdings - jedenfalls zunächst noch - voneinander lösbar. Erfindungsgemäß ist aber vorgesehen, dass in dem Kopplungszustand der erste Endabschnitt der Riegelstange mittels der Schließvorrichtung an dem Verankerungselement verriegelbar ist. Mit anderen Worten kann die genannte Lösbarkeit durch das Verriegeln nach Bedarf verhindert werden. Somit weist der Kopplungszustand zwei alternative Sicherungsstufen auf: einen unverriegelten Kopplungszustand, in dem der erste Endabschnitt der Riegelstange mit dem Verankerungselement gekoppelt ist, so dass die Riegelstange von dem Verankerungselement in ihrer Anordnung quer vor dem geschlossenen Flügel des Fensters oder der Tür gestützt wird, aber für ein reguläres Öffnen des Flügels wieder von dem Verankerungselement gelöst werden kann; und einen verriegelten Kopplungszustand, in dem die Kopplung nicht ohne Weiteres - nämlich nicht ohne ein vorangehendes Entriegeln (also ein Zurückversetzen in den unverriegelten Kopplungszustand) - gelöst werden kann, wofür vorzugsweise das Verfügen über ein Schließgeheimnis, z.B. über einen der Schließvorrichtung zugeordneten Schlüssel, erforderlich ist.In the said coupling state of the securing device, the locking rod and the anchoring element are coupled to one another by the engagement of the coupling section of the anchoring element in the coupling receptacle of the first end section of the locking bar, but - at least initially - can be detached from one another. According to the invention, however, it is provided that in the coupling state the first end section of the locking bar can be locked to the anchoring element by means of the locking device. In other words, the releasability can be prevented by locking as required. Thus, the coupling state has two alternative security levels: an unlocked coupling state in which the first end portion of the locking bar is coupled to the anchoring element so that the locking bar is supported by the anchoring element in its arrangement transversely in front of the closed wing of the window or door, but can be released from the anchoring element for a regular opening of the wing; and a locked coupling state in which the coupling cannot be released easily - namely not without a previous unlocking (i.e. returning to the unlocked coupling state), for which preferably the availability of a locking secret, e.g. via a key assigned to the locking device.
Durch das Vorsehen eines unverriegelten Kopplungszustands, in dem die Riegelstange bereits mit dem Verankerungselement gekoppelt, ein Lösen der Riegelstange aber grundsätzlich noch möglich ist, wird die Handhabung der Sicherungsvorrichtung vereinfacht. Denn so kann die Riegelstange zunächst stabil vor dem geschlossenen Flügel angeordnet werden und wird im Kopplungszustand in dieser Stellung auch gehalten, bevor die Riegelstange in einem nachfolgenden Schritt zusätzlich verriegelt werden kann, um ein unbefugtes Lösen der Riegelstange zuverlässig zu verhindern. Beim Verriegeln ist die Riegelstange somit bereits vorfixiert und braucht daher vorteilhafterweise nicht von Hand gehalten zu werden. In entsprechender Weise ist auch das Entfernen der Riegelstange zum Freigeben des Flügels vereinfacht, da die Riegelstange nach dem Entriegeln weiterhin (nun aber lösbar) mit dem Verankerungselement gekoppelt bleibt, so dass die Riegelstange auch beim Entriegeln nicht von Hand gehalten werden muss.By providing an unlocked coupling state in which the locking bar is already coupled to the anchoring element, the locking bar is released but is still possible in principle, the handling of the safety device is simplified. This is because the locking bar can initially be stably arranged in front of the closed sash and is also held in this position in the coupling state before the locking bar can be additionally locked in a subsequent step in order to reliably prevent unauthorized loosening of the locking bar. When locking the locking bar is thus already pre-fixed and therefore advantageously does not need to be held by hand. In a corresponding manner, the removal of the locking bar for releasing the wing is simplified, since the locking bar remains (but now detachably) coupled to the anchoring element after unlocking, so that the locking bar does not have to be held by hand even when unlocking.
Vorzugsweise ist die Kopplungsaufnahme des ersten Endabschnitts der Riegelstange zumindest insofern positionsfest an der Riegelstange angeordnet, als sie für ein Koppeln der Riegelstange mit dem ersten Verankerungselement nicht relativ zu der übrigen Riegelstange, insbesondere zu einem Grundkörper der Riegelstange, versetzt werden muss. Vielmehr kann das Einführen des Kopplungsabschnitts des Verankerungselements in die Kopplungsaufnahme vorzugsweise einfach dadurch erfolgen, dass die Riegelstange mit der Kopplungsaufnahme auf den Kopplungsabschnitt aufgesetzt wird.The coupling receptacle of the first end section of the locking bar is preferably arranged in a fixed position on the locking bar at least insofar as it does not have to be displaced relative to the rest of the locking bar, in particular to a base body of the locking bar, for coupling the locking bar to the first anchoring element. Rather, the coupling section of the anchoring element can preferably be introduced into the coupling receptacle simply by placing the locking bar with the coupling receptacle on the coupling section.
Gemäß einer bevorzugten Ausführungsform sind der erste Endabschnitt der Riegelstange und das Verankerungselement derart zueinander ausgebildet, dass zum Koppeln des ersten Endabschnitts mit dem Verankerungselement und/oder zum Lösen des ersten Endabschnitts von dem Verankerungselement, der erste Endabschnitt quer, d.h. insbesondere im Wesentlichen senkrecht, zu der Richtung, in welche der Kopplungsabschnitt vorsteht, und/oder quer zu der Längsachse der Riegelstange zu versetzen ist. Beispielsweise kann das Verankerungselement an einer linken Seite des Fensters oder der Tür im Bereich der Laibung montiert sein, während sein Kopplungsabschnitt zur entgegengesetzten rechten Seite weist (oder gerade umgekehrt), so dass die Riegelstange zumindest im Wesentlichen horizontal ausgerichtet quer vor dem geschlossenen Flügel angebracht werden kann (wobei grundsätzlich natürlich auch andere Ausrichtungen denkbar sind). Dann kann das Koppeln des ersten Endabschnitts der Riegelstange mit dem Verankerungselement durch Aufsetzen des ersten Endabschnitts auf das Verankerungselement insbesondere von oben, von vorne (auf die Flügelebene zu) oder von unten erfolgen. Ein Aufsetzen von oben oder unten hat dabei gegenüber einem Aufsetzen von vorne den Vorteil, dass eine Öffnungsbewegung des Flügels die Riegelstange nicht in Entkopplungsrichtung beaufschlagt, sondern senkrecht dazu, wodurch der Flügel zuverlässiger gegen ein Öffnen gesichert wird, da das Sicherheitsniveau in allen Richtungen sichergestellt wird. Ferner hat ein Aufsetzen von oben gegenüber einem Aufsetzen von unten den Vorteil, dass die Schwerkraft nicht in Entkopplungsrichtung wirkt.According to a preferred embodiment, the first end section of the locking bar and the anchoring element are designed with respect to one another in such a way that for coupling the first end section to the anchoring element and / or for releasing the first end section from the anchoring element, the first end section is transverse, ie in particular essentially perpendicular the direction in which the coupling section protrudes and / or is to be displaced transversely to the longitudinal axis of the locking bar. For example, the anchoring element can be mounted on a left side of the window or door in the region of the reveal, while its coupling section points to the opposite right side (or vice versa), so that the locking bar can be attached at least essentially horizontally aligned transversely in front of the closed wing (although in principle other orientations are of course also conceivable). Then the coupling of the first end section of the locking bar to the anchoring element can be carried out by placing the first end section on the anchoring element, in particular from above, from the front (towards the sash level) or from below. Attaching from above or below has the advantage over attaching from the front that an opening movement of the sash does not act on the locking bar in the decoupling direction, but perpendicular to it, whereby the sash is more reliably secured against opening since the level of security is ensured in all directions , Furthermore, placing from above has the advantage over placing from below that gravity does not act in the decoupling direction.
Gemäß einer vorteilhaften Weiterbildung weist die Kopplungsaufnahme des ersten Endabschnitts der Riegelstange einen offenen Umfangsabschnitt und einen geschlossenen Umfangsabschnitt auf, wobei der erste Endabschnitt der Riegelstange dazu ausgebildet ist, in einer Richtung quer zu der Längsachse der Riegelstange auf das Verankerungselement aufgesetzt zu werden, indem der Kopplungsabschnitt des Verankerungselements durch den offenen Umfangsabschnitt der Kopplungsaufnahme in die Kopplungsaufnahme eingeführt wird, und wobei in dem Kopplungszustand der Sicherungsvorrichtung der Kopplungsabschnitt des Verankerungselements von dem geschlossenen Umfangsabschnitt der Kopplungsaufnahme teilumfänglich umgriffen wird.According to an advantageous development, the coupling receptacle of the first end section of the locking bar has an open peripheral section and a closed peripheral section, the first end section of the locking bar being designed to be placed on the anchoring element in a direction transverse to the longitudinal axis of the locking bar by the coupling section of the anchoring element is inserted into the coupling receptacle through the open peripheral section of the coupling receptacle, and in the coupling state of the securing device the coupling peripheral section of the anchoring element is partially encompassed by the closed peripheral section of the coupling receptacle.
Der offenen Umfangsabschnitt und der geschlossene Umfangsabschnitt können jeweilige Teile eines Bereichs bilden, der die Kopplungsaufnahme umfänglich, insbesondere in Umfangsrichtung um die Längsachse der Riegelstange herum, umgibt. Insbesondere können der offene Umfangsabschnitt und der geschlossene Umfangsabschnitt gemeinsam den vollständigen Umfang der Kopplungsaufnahme bezüglich der Längsachse der Riegelstange bilden, d.h. der offene Umfangsabschnitt und der geschlossene Umfangsabschnitt sind entlang des vollständigen Umfangs der Kopplungsaufnahme komplementär zueinander. Der geschlossene Umfangsabschnitt ist dabei bevorzugt insofern geschlossen, als ein Entnehmen des in die Kopplungsaufnahme aufgenommenen Kopplungsabschnitts des Verankerungselements durch den ihn umgreifenden geschlossenen Umfangsabschnitt hindurch nicht möglich ist. Hierzu kann der geschlossene Umfangsabschnitt die Kopplungsaufnahme als eine Art Wand in, insbesondere zu der Längsachse der Riegelstange, radialer Richtung begrenzen. Dagegen ist der offene Umfangsabschnitt insofern offen, als der Kopplungsabschnitt des Verankerungselements durch den offenen Umfangsabschnitt in die Kopplungsaufnahme eingeführt und jedenfalls grundsätzlich auch wieder entnommen werden kann.The open circumferential section and the closed circumferential section can form respective parts of a region which surrounds the coupling receptacle circumferentially, in particular in the circumferential direction around the longitudinal axis of the locking bar. In particular, the open circumferential section and the closed circumferential section can jointly cover the entire circumference of the coupling receptacle form with respect to the longitudinal axis of the locking bar, ie the open peripheral portion and the closed peripheral portion are complementary to each other along the entire circumference of the coupling receptacle. The closed peripheral section is preferably closed insofar as it is not possible to remove the coupling section of the anchoring element received in the coupling receptacle through the closed peripheral section surrounding it. For this purpose, the closed peripheral section can delimit the coupling receptacle as a kind of wall in the radial direction, in particular to the longitudinal axis of the locking bar. In contrast, the open peripheral section is open insofar as the coupling section of the anchoring element can be inserted into the coupling receptacle through the open peripheral section and can in principle also be removed again.
Beispielsweise kann der geschlossene Umfangsabschnitt zumindest im Wesentlichen eine U-Form oder eine C-Form aufweisen, in deren Mitte die Kopplungsaufnahme ausgebildet ist. Je nach Ausrichtung des offenen Umfangsabschnitts, der dann dem Bereich zwischen den beiden Enden der U-Form bzw. der C-Form entspricht, kann festgelegt werden, aus welcher radialen Richtung die Riegelstange mit ihrem ersten Endabschnitt auf das Verankerungselement aufzusetzen ist. Vorzugsweise erstreckt sich der offene Umfangsabschnitt lediglich über einen derart geringen Teil des Gesamtumfangs um die Kopplungsaufnahme, dass der Kopplungsabschnitt des Verankerungselements zumindest in radialer Richtung im Wesentlichen lediglich aus einer einzigen Winkelrichtung in die Kopplungsaufnahme eingeführt oder aus der Kopplungsaufnahme entnommen werden kann. Ein Einführen oder Entnehmen in axialer Richtung kann dabei grundsätzlich zusätzlich möglich sein.For example, the closed peripheral section can have at least essentially a U-shape or a C-shape, in the middle of which the coupling receptacle is formed. Depending on the orientation of the open peripheral section, which then corresponds to the area between the two ends of the U-shape or the C-shape, it can be determined from which radial direction the locking bar with its first end section is to be placed on the anchoring element. The open circumferential section preferably extends only over such a small part of the total circumference around the coupling receptacle that the coupling section of the anchoring element can be inserted into the coupling receptacle or removed from the coupling receptacle essentially only from a single angular direction. In principle, insertion or removal in the axial direction may also be possible.
Gemäß einer weiteren vorteilhaften Ausführungsform weist der Kopplungsabschnitt des Verankerungselements an einem in die Richtung, in die er vorsteht, weisenden freien Ende eine Umfangsverbreiterung auf, die im Kopplungszustand der Sicherungsvorrichtung von der Kopplungsaufnahme des ersten Endabschnitts der Riegelstange, hintergriffen wird. Dazu ist der Kopplungsabschnitt mit der Umfangsverbreiterung vorzugsweise nach Art eines Pilzkopfzapfens oder eines Schraubenkopfes, insbesondere des Schraubenkopfes einer Zylinderkopfschraube, ausgebildet. Eine solche Ausformung des Kopplungsabschnitts ist nicht nur für ein Hintergreifen nützlich, sondern ermöglicht auch, die Riegelstange mit einer Kopplungsaufnahme eines zweiten Endabschnitts in Längsrichtung auf den Kopplungsabschnitt eines jeweiligen Verankerungselements aufzustecken und anschließend noch einen Bewegungsfreiheitsgrad aufzuweisen, der ein Einschwenken der Riegelstange mit ihrem ersten Endabschnitt auf den Kopplungsabschnitt eines weiteren Verankerungselements ermöglicht, wie weiter unten noch erläutert wird.According to a further advantageous embodiment, the coupling section of the anchoring element has, at a free end pointing in the direction in which it protrudes, a circumferential widening which is in the coupling state the securing device is engaged by the coupling receptacle of the first end section of the locking bar. For this purpose, the coupling section with the circumferential widening is preferably designed in the manner of a mushroom head pin or a screw head, in particular the screw head of a cylinder head screw. Such a shape of the coupling section is not only useful for reaching behind, but also enables the locking bar with a coupling receptacle of a second end section to be slipped longitudinally onto the coupling section of a respective anchoring element and then to have a degree of freedom of movement that allows the locking bar to pivot in with its first end section on the coupling section of a further anchoring element, as will be explained further below.
Beispielsweise kann das Verankerungselement eine, etwa nach DIN ausgebildete, Schraube umfassen, deren Schraubenkopf zusammen mit einem angrenzenden Teil des Schraubenschaftes den Kopplungsabschnitt des Verankerungselements bildet. Die Verwendung eines solchen einfachen Bauteils, insbesondere eines Normbauteils, zur Bildung des Kopplungsabschnitts trägt zu geringen Produktionskosten bei, ohne dass die Zuverlässigkeit der Sicherungsvorrichtung beeinträchtigt würde. Durch die Wahl einer geeigneten Festigkeitsklasse der Zylinderkopfschraube kann das Sicherheitsniveau beeinflusst werden. Die Festigkeitsklasse beträgt vorzugsweise etwa 8.8 oder 10.9, wobei 8.8 ausreichen kann.For example, the anchoring element can comprise a screw, for example designed according to DIN, the screw head of which together with an adjacent part of the screw shaft forms the coupling section of the anchoring element. The use of such a simple component, in particular a standard component, to form the coupling section contributes to low production costs without the reliability of the securing device being impaired. The safety level can be influenced by choosing a suitable strength class of the cylinder head screw. The strength class is preferably about 8.8 or 10.9, with 8.8 being sufficient.
Das genannte Hintergreifen der Umfangsverbreiterung kann insbesondere in Bezug auf eine Bewegung in zu der Ausrichtung des Kopplungsabschnitts des Verankerungselements und/oder zu der Längsachse der Riegelstange paralleler Richtung erfolgen. Mit anderen Worten wirkt das Hintergreifen einem in diese Richtung erfolgenden Entnehmen des Kopplungsabschnitts aus der Kopplungsaufnahme formschlüssig entgegen. Vorzugsweise wird die Umfangsverbreiterung des Kopplungsabschnitts dabei von einem geschlossenen Umfangsabschnitt der Kopplungsaufnahme hintergriffen, insbesondere von dem vorstehend genannten geschlossenen Umfangsabschnitt, der die Kopplungsaufnahme teilumfänglich umgibt. Dazu kann der geschlossene Umfangsabschnitt beispielsweise zumindest im Wesentlichen eine U-Form oder C-Form aufweisen, die in Längsrichtung zum Ende der Riegelstange hin verengt ist.Said engagement of the circumferential widening can take place in particular in relation to a movement in a direction parallel to the alignment of the coupling section of the anchoring element and / or to the longitudinal axis of the locking bar. In other words, the engagement behind positively counteracts a removal of the coupling section from the coupling receptacle in this direction. In this case, the circumferential widening of the coupling section is preferably a closed circumferential section of the coupling receptacle attacked, in particular by the above-mentioned closed peripheral portion which partially surrounds the coupling receptacle. For this purpose, the closed peripheral section can, for example, have at least essentially a U-shape or C-shape, which is narrowed in the longitudinal direction towards the end of the locking bar.
Ein solches Hintergreifen des Kopplungsabschnitts des Verankerungselements kann insbesondere zusätzlich zu dem genannten teilumfänglichen Umgreifen durch einen geschlossenen Umfangsabschnitt der Kopplungsaufnahme erfolgen, so dass der Kopplungsabschnitt nicht nur in radialer Richtung mit Ausnahme eines definierten schmalen Winkelbereichs, sondern auch in axialer Richtung gegen ein Entnehmen aus der Kopplungsaufnahme blockiert wird.Such a reaching behind the coupling section of the anchoring element can take place in particular in addition to the partial circumferential gripping by a closed peripheral section of the coupling receptacle, so that the coupling section not only in the radial direction with the exception of a defined narrow angular range, but also in the axial direction against removal from the coupling receptacle is blocked.
Vorzugsweise sind der Kopplungsabschnitt des Verankerungselements und die Kopplungsaufnahme des ersten Endabschnitts der Riegelstange hinsichtlich ihrer jeweiligen Maße, insbesondere hinsichtlich der Maße der genannten Umfangsverbreiterung und des genannten geschlossenen Umfangsabschnitts, derart aneinander angepasst, dass der in die Kopplungsaufnahme aufgenommene Kopplungsabschnitt zumindest im Wesentlichen lediglich einen einzigen translatorischen Freiheitsgrad aufweist. Dieser translatorische Freiheitsgrad kann dann gerade der Richtung entsprechen, in welche die Riegelstange zu versetzen ist, damit der Kopplungsabschnitt durch den offenen Umfangsabschnitt hindurch aus der Kopplungsaufnahme gelangen kann. Dabei kann es sich insbesondere um ein zu der Längsachse der Riegelstange radiales Versetzen handeln. In axialer Richtung wird der Kopplungsabschnitt zum einen durch das genannte Hintergreifen begrenzt und kann zum anderen in entgegengesetzter Richtung durch die axiale Ausdehnung der Kopplungsaufnahme begrenzt sein, so dass der Kopplungsabschnitt dann in der Kopplungsaufnahme axial festgelegt ist.The coupling section of the anchoring element and the coupling receptacle of the first end section of the locking bar are preferably matched to one another with regard to their respective dimensions, in particular with regard to the dimensions of the circumferential widening and the closed circumferential section mentioned, such that the coupling section accommodated in the coupling receptacle is at least essentially only a single translational one Has degree of freedom. This translational degree of freedom can then correspond exactly to the direction in which the locking bar is to be displaced so that the coupling section can pass through the open peripheral section from the coupling receptacle. In particular, this can be a radial offset to the longitudinal axis of the locking bar. In the axial direction, the coupling section is limited on the one hand by the engagement behind it and on the other hand can be limited in the opposite direction by the axial extent of the coupling receptacle, so that the coupling section is then axially fixed in the coupling receptacle.
Grundsätzlich kann der in der Kopplungsaufnahme aufgenommene Kopplungsabschnitt dabei noch einen Rotationsfreiheitsgrad, beispielsweise um die Längsachse der Riegelstange, aufweisen. Gegen eine solche Rotation kann die Riegelstange aber dadurch, dass sie mit einer Seitenfläche am Flügel anliegt, blockiert sein. Zudem kann eine solche Rotation auch durch die Form der Kopplungsaufnahme und des Kopplungsabschnitts formschlüssig blockiert sein.In principle, the coupling section accommodated in the coupling receptacle can also have a degree of freedom of rotation, for example around the longitudinal axis of the locking bar. However, the locking bar can be blocked against such rotation by the fact that it rests on the wing with one side face. In addition, such a rotation can also be blocked in a form-fitting manner by the shape of the coupling receptacle and the coupling section.
Gemäß einer weiteren vorteilhaften Ausführungsform umfasst die Sicherungsvorrichtung verstellbare Sperrmittel, die dazu ausgebildet sind, in dem Kopplungszustand der Sicherungsvorrichtung den Kopplungsabschnitt des Verankerungselements je nach Stellung der Sperrmittel gegen ein Austreten aus der Kopplungsaufnahme des ersten Endabschnitts zu sperren. In Verbindung mit den zuvor beschriebenen Ausführungsformen können die Sperrmittel somit dazu geeignet sein, auch den letzten translatorischen Freiheitsgrad des Kopplungsabschnitts des Verankerungselements in der Kopplungsaufnahme des ersten Endabschnitts der Riegelstange zu sperren, so dass der Kopplungsabschnitt in der Kopplungsaufnahme im Wesentlichen ohne Spiel gefangen ist. Vorzugsweise erfolgt das Sperren des Kopplungsabschnitts in der Kopplungsaufnahme formschlüssig. Wenn bereits ohne die Sperrmittel lediglich ein translatorischer Freiheitsgrad für den in die Kopplungsaufnahme aufgenommenen Kopplungsabschnitt verbleibt, können die Sperrmittel den Kopplungsabschnitt insbesondere entgegen der Richtung dieses Freiheitsgrades hintergreifen, um den Kopplungsabschnitt in der Kopplungsaufnahme vollständig zu blockieren.According to a further advantageous embodiment, the securing device comprises adjustable locking means which are designed to lock the coupling section of the anchoring element against exiting from the coupling receptacle of the first end section, depending on the position of the locking means, in the coupling state of the securing device. In conjunction with the previously described embodiments, the locking means can thus be suitable for locking the last translational degree of freedom of the coupling section of the anchoring element in the coupling receptacle of the first end section of the locking bar, so that the coupling section is caught in the coupling receptacle essentially without play. The coupling section in the coupling receptacle is preferably locked in a form-fitting manner. If only a translational degree of freedom remains for the coupling section included in the coupling receptacle without the blocking means, the blocking means can engage behind the coupling section in particular against the direction of this degree of freedom in order to completely block the coupling section in the coupling receptacle.
Insbesondere im Unterschied zu dem vorstehend beschriebenen geschlossenen Umfangsabschnitt der Kopplungsaufnahme, sind die Sperrmittel aber verstellbar, wobei von der jeweiligen Stellung der Sperrmittel abhängt, ob sie den in die Kopplungsaufnahme aufgenommenen Kopplungsabschnitt gegen ein Austreten aus der Kopplungsaufnahme sperren oder nicht. Somit ist die Sperrung des Kopplungsabschnitts in der Kopplungsaufnahme durch die Sperrmittel grundsätzlich lösbar.In particular, in contrast to the closed peripheral section of the coupling receptacle described above, the locking means are adjustable, it being dependent on the respective position of the locking means whether or not they block the coupling portion accommodated in the coupling receptacle from escaping from the coupling receptacle. Thus, the locking of the coupling section in the coupling receptacle can in principle be released.
Beispielsweise kann sich zum Lösen der Sperrung ein den Kopplungsabschnitt hintergreifendes Sperrelement der Sperrmittel in eine Stellung zurückdrängen lassen, in welcher die Sperrmittel den Kopplungsabschnitt für ein Austreten aus der Kopplungsaufnahme freigeben. Auch um den Kopplungsabschnitt in die Kopplungsaufnahme einzuführen, kann es erforderlich sein, ein solches Sperrelement zumindest vorübergehend in eine derartige Stellung zurückzudrängen. Nachdem der Kopplungsabschnitt dann vollständig in die Kopplungsaufnahme eingeführt ist, kann das Sperrelement in eine den Kopplungsabschnitt in der Kopplungsaufnahme sperrende Stellung versetzt werden, wobei es vorzugsweise, etwa aufgrund einer Vorspannung, automatisch in diese sperrende Stellung versetzt wird. Insbesondere können nicht nur das Sperrelement, sondern auch alle losen Teile der Schließvorrichtung federvorgespannt sein, um eine rappelfreie Handhabung zu gewährleisten.For example, in order to release the blocking, a blocking element of the blocking means engaging behind the coupling section can be pushed back into a position in which the blocking means release the coupling section for exiting the coupling receptacle. Also, in order to insert the coupling section into the coupling receptacle, it may be necessary to at least temporarily push such a locking element back into such a position. After the coupling section is then fully inserted into the coupling receptacle, the locking element can be moved into a position blocking the coupling section in the coupling receptacle, it preferably being automatically moved into this blocking position, for example due to a preload. In particular, not only the locking element, but also all the loose parts of the locking device can be spring-biased in order to ensure jam-free handling.
Insofern kann der Kopplungsabschnitt in die Kopplungsaufnahme einrasten, so dass er nach Erreichen der Kopplungsaufnahme vorteilhafterweise automatisch durch die Rastwirkung in der Kopplungsaufnahme gehalten wird. Ein Entnehmen des Kopplungsabschnitts aus der Kopplungsaufnahme kann dabei, insbesondere gegen einen überwindbaren Widerstand der Sperrmittel und insofern ausrastend, noch möglich sein. Die Sperrmittel tragen folglich dazu bei, den Kopplungszustand der Sicherungsvorrichtung, in welchem die Riegelstange durch Eingreifen des Kopplungsabschnitts des Verankerungselements in die Kopplungsaufnahme des ersten Endabschnitts mit dem Verankerungselement gekoppelt ist, zu stabilisieren. Auf diese Wiese kann bereits im noch unversiegelten Kopplungszustand ein zuverlässiger Halt der quer vor dem zu sichernden geschlossenen Flügel angeordneten Riegelstange erreicht werden.In this respect, the coupling section can snap into the coupling receptacle, so that it is advantageously automatically held in the coupling receptacle by the latching action after the coupling receptacle has been reached. It may still be possible to remove the coupling section from the coupling receptacle, in particular against an insurmountable resistance of the locking means and in this respect snapping out. The locking means thus help to stabilize the coupling state of the securing device, in which the locking bar is coupled to the anchoring element by engagement of the coupling section of the anchoring element in the coupling receptacle of the first end section. In this way, a reliable hold of the locking bar arranged transversely in front of the closed wing to be secured can be achieved even in the still unsealed coupling state.
Gemäß einer vorteilhaften Weiterbildung umfassen die Sperrmittel eine an dem Kopplungsabschnitt des Verankerungselements ausgebildete Eingriffsvertiefung sowie ein an dem ersten Endabschnitt der Riegelstange beweglich gelagertes Sperrelement, das dazu ausgebildet ist, zum Sperren des Kopplungsabschnitts gegen ein Austreten aus der Kopplungsaufnahme des ersten Endabschnitts in die Eingriffsvertiefung einzugreifen. Das Sperrelement kann etwa als eine massive Kugel, insbesondere aus hartem Metall, ausgebildet sein. Eine Kugelform hat dabei den Vorteil, dass sie eine hohe Stabilität aufweist, während die runde Oberfläche zugleich dazu beitragen kann, dass sich das Sperrelement beim Einführen oder Entnehmen des Kopplungsabschnitts in die bzw. aus der Kopplungsaufnahme leicht zurückdrängen lässt. Das Sperrelement kann aber auch eine andere Form aufweisen, insbesondere eine Form, durch deren Eingriff in die Eingriffsvertiefung die Riegelstange formschlüssig gegen eine Rotation um ihre Längsachse gesperrt werden kann. Beispielsweise kann die Eingriffsvertiefung als Innensechskant ausgebildet sein, während das Sperrelement eine Außensechskantform aufweist.According to an advantageous development, the locking means comprise an engagement recess formed on the coupling section of the anchoring element and a movable recess on the first end section of the locking bar Locking element which is designed to engage the engagement recess in order to lock the coupling section against escaping from the coupling receptacle of the first end section. The locking element can be designed as a solid ball, in particular made of hard metal. A spherical shape has the advantage that it has a high stability, while the round surface can also contribute to the locking element being easily pushed back into or out of the coupling receptacle when the coupling section is inserted or removed. However, the locking element can also have a different shape, in particular a shape by the engagement of which in the engagement recess, the locking bar can be locked against rotation about its longitudinal axis. For example, the engagement recess can be designed as an internal hexagon, while the locking element has an external hexagon shape.
Die Eingriffsvertiefung ist vorzugsweise in einer Stirnseite des Kopplungsabschnitts des Verankerungselements ausgebildet, die in die Richtung weist, in die der Kopplungsabschnitt vorsteht. Bei einem quer zu dieser Richtung erfolgenden Einführen oder Entnehmen des Kopplungsabschnitts in die bzw. aus der Kopplungsaufnahme wird der Kopplungsabschnitt durch das Eingreifen des Sperrelements in die Stirnseite somit besonders zuverlässig formschlüssig gesperrt. Wenn das Verankerungselement eine DIN-Schraube umfasst, deren schraubenkopfseitiger Teil den Kopplungsabschnitt bildet, kann eine solche stirnseitige Eingriffsvertiefung auch durch einen Schraubenkopfantrieb gebildet werden, der für den Eingriff eines Schraubendrehers vorteilhafterweise ohnehin vorgesehen ist. Beispielsweise kann der Schraubenkopf nach DIN EN ISO 4762 ausgebildet sein oder jedenfalls einen Innensechskant aufweisen, der als Eingriffsvertiefung fungieren kann, in die das jeweilige Sperrelement, das nicht unbedingt exakt komplementär ausgebildet sein muss, zum Sperren eingreifen kann.The engagement recess is preferably formed in an end face of the coupling section of the anchoring element, which faces in the direction in which the coupling section protrudes. When the coupling section is inserted or removed transversely to this direction into or out of the coupling receptacle, the coupling section is thus particularly reliably locked in a form-fitting manner by the engagement of the locking element in the end face. If the anchoring element comprises a DIN screw, the screw head-side part of which forms the coupling section, such an engagement recess on the end face can also be formed by a screw head drive, which is advantageously provided anyway for the engagement of a screwdriver. For example, the screw head can be designed in accordance with DIN EN ISO 4762 or in any case have an internal hexagon that can act as an engagement recess into which the respective locking element, which does not necessarily have to be exactly complementary, can engage for locking.
Gemäß einer weiteren vorteilhaften Ausführungsform ist die Schließvorrichtung dazu ausgebildet, zum Verriegeln des ersten Endabschnitts der Riegelstange an dem Verankerungselement die Sperrmittel in einer Stellung zu blockieren, in der sie den Kopplungsabschnitt des Verankerungselements gegen ein Austreten aus der Kopplungsaufnahme des ersten Endabschnitts sperren. Da die Sperrmittel versetzbar sind und es von ihrer jeweiligen Stellung abhängt, ob sie den Kopplungsabschnitt in der Kopplungsaufnahme sperren, ist es für ein zuverlässiges Verriegeln des ersten Endabschnitts der Riegelstange an dem Verankerungselement zweckmäßig, die Sperrmittel in der sperrenden Stellung nach Bedarf zu blockieren. Dazu kann vorteilhafterweise die Schließvorrichtung verwendet werden, durch deren Betätigung die Sperrmittel blockiert werden können bzw. die Blockade wieder gelöst werden kann. Vorteilhafterweise ist die Schließvorrichtung dabei dazu ausgebildet, dass das Lösen der Blockade zum Freigeben der Sperrmittel (und somit auch zum Freigeben des andernfalls in der Kopplungsaufnahme gefangenen Kopplungsabschnitts) ein Schließgeheimnis, etwa einen Code oder einen Schlüssel, voraussetzt. Auf diese Weise ist die Verriegelung auch dann gegen ein Entriegeln gesichert, wenn die Schließvorrichtung, etwa durch Einschlagen einer Scheibe, für einen Unbefugten zugänglich ist.According to a further advantageous embodiment, the locking device is designed to block the locking means for locking the first end section of the locking bar on the anchoring element in a position in which they block the coupling section of the anchoring element against escaping from the coupling receptacle of the first end section. Since the locking means are displaceable and it depends on their respective position whether they lock the coupling section in the coupling receptacle, it is expedient for reliably locking the first end section of the locking bar to the anchoring element to block the locking means in the locking position as required. For this purpose, the locking device can advantageously be used, the actuation of which can block the blocking means or the blocking can be released again. Advantageously, the locking device is designed so that the release of the blockage to release the locking means (and thus also to release the coupling section that is otherwise caught in the coupling receptacle) requires a locking secret, for example a code or a key. In this way, the lock is also secured against unlocking if the locking device is accessible to an unauthorized person, for example by breaking a window.
Insbesondere kann die Schließvorrichtung dazu ausgebildet sein, zum Verriegeln des ersten Endabschnitts der Riegelstange an dem Verankerungselement das in die Eingriffsvertiefung des Verankerungselements eingreifende Sperrelement gegen ein Zurückweichen in Richtung der Riegelstange und/oder entlang der Längsachse der Riegelstange zu blockieren.In particular, the locking device can be designed to lock the first end section of the locking bar on the anchoring element to block the locking element engaging in the engagement recess of the anchoring element against backing away in the direction of the locking bar and / or along the longitudinal axis of the locking bar.
Gemäß einer vorteilhaften Weiterbildung umfasst die Schließvorrichtung einen Blockierkörper, in den ein Schließzylinder aufgenommen ist und der in Abhängigkeit von einem Schließzustand des Schließzylinders quer zur Beweglichkeit des Sperrelements zwischen einer Verriegelungsstellung, in der er das Sperrelement zum Verriegeln des ersten Endabschnitts der Riegelstange an dem Verankerungselement in einer sperrenden Stellung blockiert, und einer Freigabestellung verstellbar ist, in der er das Sperrelement nicht blockiert. Der genannte Schließzustand hängt dabei vorzugsweise davon ab, ob der Schließzylinder mit einem dem Schließzylinder zugeordneten Schlüssel betätigt wird. Die Verwendung des richtigen Schlüssels kann dabei Voraussetzung sowohl für das Verstellen des Blockierkörpers in die Verriegelungsstellung als auch für das Verstellen des Blockierkörpers in die Freigabestellung sein. Vorzugsweise liegt aber eine Automatikfunktion vor, d.h. dass sich der Blockierkörper auch ohne Schlüssel in die Verriegelungsstellung verstellen lässt, aber nur mittels des zugeordneten Schlüssels aus der Verriegelungsstellung in die Freigabestellung verstellen lässt. Zudem kann der Blockierkörper in die Freigabestellung vorgespannt sein, so dass zum einen verhindert wird, dass er ohne Betätigung in die Verriegelungsstellung gelangt, und er zum anderen aus der Verriegelungsstellung durch Betätigung des Schließzylinders mittels des zugeordneten Schlüssels automatisch in die Freigabestellung versetzt wird.According to an advantageous development, the locking device comprises a blocking body in which a locking cylinder is received and which, depending on a locking state of the locking cylinder, transversely to the mobility of the locking element between a locking position in which it holds the locking element for locking the first end section of the locking bar on the anchoring element blocked in a locking position, and a release position is adjustable in which it does not block the locking element. The said locking state preferably depends on whether the locking cylinder is actuated with a key assigned to the locking cylinder. The use of the correct key can be a prerequisite both for moving the blocking body into the locking position and for moving the blocking body into the release position. However, there is preferably an automatic function, that is to say that the blocking body can also be moved into the locking position without a key, but can only be moved from the locking position into the release position by means of the assigned key. In addition, the blocking body can be biased into the release position, so that on the one hand it is prevented from reaching the locking position without actuation, and on the other hand it is automatically moved from the locking position to the release position by actuating the locking cylinder by means of the assigned key.
Bei einer Ausführungsform mit verstellbarem Blockierkörper ist es ferner vorteilhaft, wenn der Blockierkörper in der Freigabestellung quer zur Längsachse der Riegelstange aus der Riegelstange vorsteht und in der Verriegelungsstellung in die Riegelstange hinein versetzt ist, insbesondere bündig mit einer Seitenfläche der Riegelstange abschließt. Die jeweilige Stellung des Blockierkörpers und somit der Sicherungszustand der Sicherungsvorrichtung sind dann für einen Nutzer einfach, auch aus einer gewissen Entfernung noch, zu erkennen. Wenn der Kopplungszustand der Sicherungsvorrichtung vorliegt, die Riegelstange also über ihren ersten Endabschnitt mit dem Verankerungselement verbunden ist, kann das Verriegeln dann einfach dadurch erfolgen, dass der Blockierkörper in die Riegelstange hinein gedrückt wird, wozu vorteilhafterweise kein Schlüssel erforderlich ist.In an embodiment with an adjustable blocking body, it is also advantageous if the blocking body protrudes from the locking bar transversely to the longitudinal axis of the locking bar in the release position and is displaced into the locking bar in the locking position, in particular is flush with a side surface of the locking bar. The respective position of the blocking body and thus the security status of the security device are then easy for a user to recognize, even from a certain distance. If the locking device is in the coupled state, that is to say the locking bar is connected to the anchoring element via its first end section, the locking can then be carried out simply by pressing the blocking body into the locking bar, for which purpose advantageously no key is required.
Gemäß einer weiteren vorteilhaften Ausführungsform sind die Riegelstange und das Verankerungselement dazu ausgebildet, dass die Riegelstange in dem Kopplungszustand der Sicherungsvorrichtung an der Laibung des Fensters oder der Tür im Wesentlichen flächig anliegt. Vorzugsweise greift die Riegelstange dabei nicht in die Laibung ein, sondern erstreckt sich lediglich bis zur Laibung. Insbesondere kann die Riegelstange in dem Kopplungszustand mit einer Stirnseite ihres ersten Endabschnitts an der Laibung anliegen. Dabei kann ein entgegengesetzter zweiter Endabschnitt der Riegelstage vorteilhafterweise in entsprechender Weise flächig an einer entgegengesetzten Seite der Laibung anliegen. Flächig liegt die Riegelstange dabei insbesondere insofern an, als sie mit einer zur Laibung ausgerichteten Fläche parallel zur Laibung angeordnet ist, wobei kein oder ein lediglich geringer Spalt zwischen der Fläche und der Laibung verbleibt. Die Riegelstange schließt dann, vorzugsweise an ihren beiden Enden, zumindest im Wesentlichen bündig an die Laibung an. Somit kann bereits dadurch die vor dem zu sichernden Flügel angeordnete Riegelstange in Richtung ihrer Längsachse axial festgelegt sein. Des Weiteren trägt zur zuverlässigen Anbringung der Riegelstange vor dem zu sichernden Fenster bei, wenn durch das Zusammenwirken der jeweilige Kopplungsaufnahme und des jeweiligen darin aufgenommenen Kopplungsabschnitts eine große Überdeckung der Riegelstange mit dem jeweiligen Verankerungselement erreicht wird.According to a further advantageous embodiment, the locking bar and the anchoring element are designed so that the locking bar in the coupled state the securing device is substantially flat against the reveal of the window or door. The locking bar preferably does not engage in the reveal, but only extends to the reveal. In particular, in the coupling state, the locking bar can rest on the reveal with an end face of its first end section. In this case, an opposite second end section of the locking days can advantageously lie flat against an opposite side of the reveal in a corresponding manner. The locking bar rests flatly in particular in that it is arranged parallel to the reveal with a surface aligned with the reveal, with no or only a slight gap remaining between the surface and the reveal. The locking bar then connects, preferably at both ends, at least essentially flush with the reveal. Thus, the locking bar arranged in front of the wing to be secured can already be axially fixed in the direction of its longitudinal axis. Furthermore, it contributes to the reliable attachment of the locking bar in front of the window to be secured if a large overlap of the locking bar with the respective anchoring element is achieved by the interaction of the respective coupling receptacle and the respective coupling section accommodated therein.
Allgemein ist es für die Zuverlässigkeit der Sicherung vorteilhaft, wenn zumindest im verriegelten Kopplungszustand der Sicherungsvorrichtung der erste Endabschnitt der Riegelstange in alle Raumrichtungen formschlüssig an dem Verankerungselement festgelegt ist. Auf diese Weise kann das Spiel der vor dem Flügel angebrachten Riegelstange minimiert werden. Die formschlüssige Festlegung kann auch schon im unverriegelten Kopplungszustand vorliegen, in dem die Riegelstange zwar noch von dem Verankerungselement lösbar ist, aber dennoch durchaus formschlüssig abgestützt sein kann, auch wenn diese formschlüssige Abstützung ohne die zusätzliche Verriegelung überwindbar ist.In general, it is advantageous for the reliability of the securing if, at least in the locked coupling state of the securing device, the first end section of the locking bar is positively attached to the anchoring element in all spatial directions. In this way, the play of the locking bar attached in front of the wing can be minimized. The form-fitting fixing can also be present in the unlocked coupling state, in which the locking bar can still be detached from the anchoring element, but can nevertheless be supported in a form-fitting manner, even if this form-fitting support can be overcome without the additional locking.
Gemäß einer vorteilhaften Ausführungsform umfasst das Verankerungselement einen bolzenförmigen Montageabschnitt sowie eine Siebhülse und ist dazu ausgebildet, mit der Siebhülse sowie dem darin aufgenommenen Montageabschnitt in einer Bohrung im Bereich der Laibung des Fensters oder der Tür angeordnet und mittels Injektionsmörtel befestigt zu werden. Das Anbringen einer Riegelstange, deren Länge nicht verstellbar ist, durch im Wesentlichen spielfreie Kopplung mit jeweiligen Verankerungselementen kann eine exakte Positionierung der Verankerungselemente in der Laibung erfordern. Dazu kann das Verankerungselement grundsätzlich einfach eingeschraubt oder verdübelt werden, wobei das jeweilige Sicherheitsniveau unter anderem von der Überdeckung des Verankerungselement mit der Laibung bzw. dem Wandbereich abhängt. Eine besonders vorteilhafte Befestigungsmöglichkeit ergibt sich durch die Verwendung einer Siebhülse, durch die in Verbindung mit Injektionsmörtel vergleichsweise einfach eine exakte Positionierung des Verankerungselements erreicht werden kann.According to an advantageous embodiment, the anchoring element comprises a bolt-shaped mounting section and a sieve sleeve and is designed to be arranged with the sieve sleeve and the mounting section accommodated therein in a bore in the region of the reveal of the window or door and to be fastened by means of injection mortar. The attachment of a locking bar, the length of which cannot be adjusted, by coupling with respective anchoring elements without play, may require exact positioning of the anchoring elements in the reveal. For this purpose, the anchoring element can in principle simply be screwed in or dowelled, the respective level of security depending, among other things, on the overlap of the anchoring element with the reveal or the wall area. A particularly advantageous fastening possibility results from the use of a sieve sleeve, through which an exact positioning of the anchoring element can be achieved comparatively easily in connection with injection mortar.
Denn nach Einsetzen der Siebhülse in die Bohrung und Füllen der Siebhülse mit Injektionsmörtel, kann der bolzenförmige Montageabschnitt des Verankerungselements in die Siebhülse eingeschoben werden, so dass er von dem Injektionsmörtel umgeben ist. Solange der Injektionsmörtel dann noch nicht ausgehärtet ist, können der Montageabschnitt und der damit verbundene Kopplungsabschnitt des Verankerungselements noch bewegt werden. In diesem Zustand kann die Riegelstange mit dem Verankerungselement gekoppelt werden, wodurch der noch bewegliche Kopplungsabschnitt eine für die Kopplung mit der Riegelstange korrekt ausgerichtete Position einnimmt. In dieser Position wird das Verankerungselement dann durch den aushärtenden Injektionsmörtel festgelegt. Auf diese Weise können etwa auch Montageungenauigkeiten z.B. infolge verlaufender Bohrer ausgeglichen werden. Bei dem genannten Montageabschnitt kann es sich insbesondere um zumindest einen Teil des Schafts einer Schraube, beispielsweise einer Zylinderkopfschraube, handeln, wobei der Kopplungsabschnitt durch den Schraubenkopf sowie gegebenenfalls einen übrigen Teil des Schafts gebildet werden kann.After inserting the sieve sleeve into the bore and filling the sieve sleeve with injection mortar, the bolt-shaped mounting section of the anchoring element can be inserted into the sieve sleeve so that it is surrounded by the injection mortar. As long as the injection mortar has not yet hardened, the mounting section and the coupling section of the anchoring element connected to it can still be moved. In this state, the locking bar can be coupled to the anchoring element, as a result of which the still movable coupling section assumes a position which is correctly aligned for the coupling to the locking bar. In this position, the anchoring element is then fixed by the hardening injection mortar. In this way, assembly inaccuracies, for example as a result of running drills, can also be compensated for. The assembly section mentioned can in particular be at least a part of the shaft of a screw, for example a cylinder head screw, the coupling section being able to be formed by the screw head and, if appropriate, a remaining part of the shaft.
Für eine stabile Verankerung der Sicherungsvorrichtung wird das Verankerungselement vorteilhafterweise zumindest teilweise in die Laibung eingreifend montiert, etwa eingeschraubt oder eingedübelt, beispielsweise wie vorstehend beschrieben unter Verwendung einer Siebhülse. Eine Bohrung, die zur Aufnahme eines Teils des Verankerungselements in der Laibung gegebenenfalls vorgesehen werden muss, ist dabei vorzugsweise parallel zur Flügelebene und senkrecht zur Oberfläche der Laibung in der Laibung ausgebildet. Ein besonders kompaktes Verankerungselement ergibt sich, wenn das Verankerungselement lediglich mit dem Kopplungsabschnitt aus der Bohrung heraus über die Laibung vorsteht und sich der Kopplungsabschnitt dabei entlang der Achse der Bohrung erstreckt. Die Bohrung in der Laibung zur Befestigung des Verankerungselements kann daher insbesondere in Verlängerung der vor dem zu sichernden Flügel angeordneten Riegelstange vorzusehen sein. Dort eine Bohrung vorzusehen, kann aber unter Umständen baulich problematisch sein. Beispielsweise kann in dem Bereich, in dem die Riegelstange mit ihrem ersten Endabschnitt an der Laibung anbringbar sein soll, eine Dämmung vorgesehen sein, die durch eine Bohrung beeinträchtigt würde.For a stable anchoring of the securing device, the anchoring element is advantageously mounted, at least partially engaging in the reveal, for example screwed or dowelled, for example as described above using a sieve sleeve. A bore, which may have to be provided for receiving a part of the anchoring element in the reveal, is preferably formed parallel to the wing plane and perpendicular to the surface of the reveal in the reveal. A particularly compact anchoring element is obtained if the anchoring element only protrudes with the coupling section out of the hole beyond the reveal and the coupling section extends along the axis of the hole. The hole in the reveal for fastening the anchoring element can therefore be provided in particular in the extension of the locking bar arranged in front of the wing to be secured. Providing a hole there can be structurally problematic under certain circumstances. For example, in the area in which the locking bar is to be attachable to the reveal with its first end section, insulation can be provided which would be impaired by a bore.
Beispielsweise in einem solchen Fall ist eine Ausführungsform vorteilhaft, bei der die Sicherungsvorrichtung zumindest ein Verankerungselement umfasst, das einen Kopplungsabschnitt zur Kopplung des ersten Endabschnitts der Riegelstange mit dem Verankerungselement sowie zumindest einen Montageabschnitt aufweist, der dazu ausgebildet ist, in einer Bohrung im Bereich der Laibung des Fensters oder der Tür angeordnet und befestigt zu werden, wobei der Kopplungsabschnitt und der Montageabschnitt zueinander versetzt parallel ausgerichtet sind. Ein solcher Versatz zwischen dem in die Bohrung einzusetzenden Montageabschnitt und dem mit dem ersten Endabschnitt der Riegelstange koppelbaren Kopplungsabschnitt kann beispielsweise dadurch erreicht werden, dass das Verankerungselement eine Basisplatte aufweist, von der aus sich an ihrer einen Flachseite der Kopplungsabschnitt und an ihrer anderen Flachseite der Montageabschnitt von jeweils unterschiedlichen Ausgangspunkten aus parallel zueinander und vorzugsweise jeweils senkrecht zur Basisplatte erstrecken. Dabei, aber auch ganz allgemein, kann es zur Erhöhung der Stabilität der Verankerung vorteilhaft sein, wenn ein jeweiliges Verankerungselement mehrere, insbesondere gleichartige, Montageabschnitte aufweist.For example, in such a case, an embodiment is advantageous in which the securing device comprises at least one anchoring element which has a coupling section for coupling the first end section of the locking bar to the anchoring element and at least one mounting section which is designed to be in a bore in the region of the reveal of the window or the door to be arranged and fastened, the coupling section and the mounting section being offset parallel to one another and aligned. Such an offset between the mounting section to be inserted into the bore and the coupling section that can be coupled to the first end section of the locking bar can be achieved, for example, in that the anchoring element has a base plate, from which the coupling section on one flat side and the mounting section on its other flat side of each extend from different starting points parallel to each other and preferably perpendicular to the base plate. In this case, but also very generally, it can be advantageous to increase the stability of the anchoring if a respective anchoring element has several, in particular identical, mounting sections.
Gemäß einer weiteren vorteilhaften Ausführungsform umfasst die Sicherungsvorrichtung zumindest zwei Verankerungselemente mit jeweils einem Kopplungsabschnitt, wobei die Riegelstange einen dem ersten Endabschnitt bezüglich der Längsachse der Riegelstange entgegengesetzten zweiten Endabschnitt mit einer Kopplungsaufnahme aufweist, der dazu ausgebildet ist, mit einem jeweiligen der Verankerungselemente lösbar gekoppelt zu werden, indem in dem Kopplungszustand der Sicherungsvorrichtung der Kopplungsabschnitt des jeweiligen Verankerungselements in die Kopplungsaufnahme des zweiten Endabschnitts der Riegelstange eingreift. Auf diese Weise kann die Riegelstange an beiden Enden ihrer Längserstreckung mit einem jeweiligen Verankerungselement gekoppelt werden, um im Kopplungszustand quer vor dem zu sichernden geschlossenen Flügel angeordnet beidseitig zuverlässig gehalten zu werden. Zweckmäßigerweise werden die Verankerungselemente dazu an entgegengesetzten Seiten des Flügels dauerhaft fest montiert.According to a further advantageous embodiment, the securing device comprises at least two anchoring elements, each with a coupling section, the locking bar having a second end section opposite the first end section with respect to the longitudinal axis of the locking bar with a coupling receptacle, which is designed to be detachably coupled to a respective one of the anchoring elements by engaging in the coupling state of the securing device, the coupling section of the respective anchoring element in the coupling receptacle of the second end section of the locking bar. In this way, the locking bar can be coupled to a respective anchoring element at both ends of its longitudinal extent in order to be reliably held on both sides in the coupling state, arranged transversely in front of the closed wing to be secured. For this purpose, the anchoring elements are expediently permanently permanently mounted on opposite sides of the wing.
Der erste und der zweite Endabschnitt der Riegelstange können unterschiedlich ausgebildet sein. Vorzugsweise sind sie aber zumindest insofern einander funktional entsprechend ausgebildet, als sie jeweils mit einem beliebigen jeweiligen Verankerungselement koppelbar sind. Mit anderen Worten können sowohl der erste als auch der zweite Endabschnitt der Riegelstange wahlweise mit dem einen oder auch mit dem anderen der zwei Verankerungselemente gekoppelt werden. Beim Anbringen der Riegelstange braucht somit nicht darauf geachtet zu werden, die Riegelstange bezüglich ihrer Endabschnitte korrekt auszurichten.The first and the second end section of the locking bar can be designed differently. However, they are preferably designed to be functionally corresponding to one another at least insofar as they can each be coupled to any respective anchoring element. In other words, both the first and the second end section of the locking bar can optionally be coupled to one or to the other of the two anchoring elements. When attaching the locking bar, it is therefore not necessary to take care to correctly align the locking bar with respect to its end sections.
Die zwei Verankerungselemente sind dabei zumindest hinsichtlich der Ausbildung ihres jeweiligen Kopplungsabschnitts vorzugsweise gleichartig ausgebildet. Insbesondere können sie baugleich ausgebildet sein, wodurch die Herstellung der Verankerungselemente vereinfacht wird. Grundsätzlich kann die Sicherungsvorrichtung aber auch verschiedene Verankerungselemente umfassen, die dann vorteilhafterweise, insbesondere aufgrund der genannten Gleichartigkeit ihrer Kopplungsabschnitte, jeweils zu beiden Endabschnitten der Riegelstange kompatibel sind. Verschiedene Verankerungselemente können beispielsweise dann vorgesehen werden, wenn auf einer Seite des Flügels eine wie vorstehend beschrieben versetzte Befestigung des Verankerungselements erforderlich ist, nicht aber auf der anderen Seite des Flügels, oder wenn z.B. bei einem mehrflügeligen Fenster ein Flügel auf einer Seite an die Laibung, auf der anderen Seite aber an einen Mittelsteg zwischen diesem und einem weiteren Flügel grenzt, so dass an diesem Mittelsteg ein spezielles Verankerungselement verwendet werden muss, das senkrecht zu der Richtung, in die sein Kopplungsabschnitt vorsteht, zu montieren ist.The two anchoring elements are preferably of identical design, at least with regard to the design of their respective coupling section. In particular, they can be of identical construction, which simplifies the manufacture of the anchoring elements. In principle, however, the securing device can also comprise various anchoring elements, which are then advantageously compatible with both end sections of the locking bar, in particular because of the similarity of their coupling sections. Various anchoring elements can be provided, for example, if an anchoring of the anchoring element as described above is required on one side of the wing, but not on the other side of the wing, or if e.g. in the case of a multi-sash window, a sash borders on the reveal on one side, but on the other side it borders on a central web between this and another sash, so that a special anchoring element must be used on this central web, which is perpendicular to the direction in which Coupling section protrudes, is to be assembled.
Gemäß einer vorteilhaften Weiterbildung ist die Kopplungsaufnahme des zweiten Endabschnitts der Riegelstange dazu ausgebildet, im Wesentlichen entlang der Längsachse der Riegelstange auf den Kopplungsabschnitt des jeweiligen Verankerungselements aufgesetzt zu werden, wobei in dem Kopplungszustand der Sicherungsvorrichtung der Kopplungsabschnitt des jeweiligen Verankerungselements von der Kopplungsaufnahme des zweiten Endabschnitts vorzugsweise vollumfänglich umgriffen wird. Mit anderen Worten gelangt bei dem zweiten Endabschnitt der Riegelstange der Kopplungsabschnitt des zu koppelnden Verankerungselements in zumindest im Wesentlichen axialer Richtung bezüglich der Längsachse der Riegelstange in die am zweiten Endabschnitt ausgebildete Kopplungsaufnahme. Somit unterscheidet sich die Kopplung des zweiten Endabschnitts mit einem jeweiligen Verankerungselement insbesondere von der vorstehend als eine mögliche Ausführungsform beschriebenen Kopplung des ersten Endabschnitts mit einem jeweiligen Verankerungselement, die nicht axial, sondern durch ein Versetzen der Riegelstange quer zur Längsachse erfolgt.According to an advantageous development, the coupling receptacle of the second end section of the locking bar is designed to be placed essentially along the longitudinal axis of the locking bar on the coupling section of the respective anchoring element, with the coupling section of the respective anchoring element preferably being separated from the coupling receptacle of the second end section in the coupling state of the securing device is fully encompassed. In other words, in the second end section of the locking bar, the coupling section of the anchoring element to be coupled arrives in the coupling receptacle formed on the second end section in at least substantially the axial direction with respect to the longitudinal axis of the locking bar. The coupling of the second end section to a respective anchoring element thus differs in particular from the coupling of the first end section described above as a possible embodiment with a respective anchoring element, which does not take place axially, but rather by displacing the locking bar transversely to the longitudinal axis.
Bei der vorliegenden Ausführungsform kann die Riegelstange beispielsweise zunächst etwas schräg zur Flügelebene ausgerichtet entlang ihrer Längsachse mit ihrem zweiten Endabschnitt auf das Verankerungselement aufgesteckt und anschließend zum Flügel hin eingeschwenkt werden, bis sie parallel am Flügel anliegt und dabei insbesondere die Laibung vollständig durchspannt. Durch dieses Einschwenken kann dann zugleich die Kopplung des ersten Endabschnitts mit dem anderen Verankerungselement an der entgegengesetzten Seite des Flügels erfolgen. Vorzugsweise sind die Kopplungsabschnitte dabei derart ausgebildet, dass bei auf ein Verankerungselement aufgestecktem zweitem Endabschnitt für die Riegelstange ein Bewegungsfreiheitsgrad verbleibt, so dass der erste Endabschnitt durch Einschwenken aus einer jeweiligen Richtung seitlich auf den Kopplungsabschnitt des jeweils anderen Verankerungselements aufgeschoben werden kann. Zumindest der Kopplungsabschnitt, der mit dem ersten Endabschnitt zusammenwirkt, weist zudem vorzugsweise eine Verriegelungsgeometrie, insbesondere die vorstehend beschriebene Eingriffsvertiefung z.B. in Form eines Sechskantlochs, auf.In the present embodiment, the locking bar can, for example, first be aligned somewhat obliquely to the wing plane along its longitudinal axis with its second end section, and then pivoted toward the wing until it lies parallel to the wing and in particular completely spans the reveal. This pivoting in then also enables the coupling of the first end section to the other anchoring element on the opposite side of the wing. The coupling sections are preferably designed such that when the second end section is slipped onto an anchoring element, a degree of freedom of movement remains for the locking bar, so that the first end section can be pushed laterally onto the coupling section of the other anchoring element by pivoting in from a respective direction. At least the coupling section, which cooperates with the first end section, also preferably has a locking geometry, in particular the engagement recess described above, e.g. in the form of a hexagon hole.
Wenn die Kopplungsaufnahme des zweiten Endabschnitts dazu ausgebildet ist, den darin aufgenommenen Kopplungsabschnitt vollständig zu umgreifen, kann der Kopplungsabschnitt vorteilhafterweise auch ausschließlich axial wieder aus der Kopplungsaufnahme herausgeführt werden. In eine Richtung quer zur Längsachse der Riegelstange ist ein Lösen der Riegelstange von dem jeweiligen Verankerungselement dagegen blockiert. Auf diese Weise braucht die Schließvorrichtung der Riegelstange vorteilhafterweise nicht zusätzlich auch mit dem zweiten Endabschnitt zusammenzuwirken, um auch dessen Kopplung mit dem jeweiligen Verankerungselement zu verriegeln. Vielmehr kann es reichen, mittels der Schließvorrichtung lediglich den in die Kopplungsaufnahme des ersten Endabschnitts aufgenommenen Kopplungsabschnitt des jeweiligen Verankerungselements gegen ein Austreten zu sperren. Denn bereits dadurch kann die Riegelstange axial unbeweglich festgelegt sein, so dass auch an dem zweiten Endabschnitt der Kopplungsabschnitt des jeweiligen Verankerungselements nicht aus der Kopplungsaufnahme austreten kann, da dies nur durch axiales Versetzen der Riegelstange möglich wäre.If the coupling receptacle of the second end section is designed to completely encompass the coupling section accommodated therein, the coupling section can advantageously also be guided axially out of the coupling receptacle again. In contrast, in a direction transverse to the longitudinal axis of the locking bar, the locking bar is blocked from being released from the respective anchoring element. In this way, the locking device of the locking bar advantageously does not also have to interact with the second end section in order to also lock its coupling to the respective anchoring element. Rather, it can be sufficient, by means of the locking device, only that which is received in the coupling receptacle of the first end section To block the coupling section of the respective anchoring element against escaping. This is because the locking bar can already be fixed so that it cannot move axially, so that the coupling section of the respective anchoring element cannot emerge from the coupling receptacle at the second end section, since this would only be possible by axially displacing the locking bar.
Dass die Schließvorrichtung lediglich mit dem ersten Endabschnitt zusammenwirken muss und auch keine weitere Schließvorrichtung für den zweiten Endabschnitt vorgesehen werden muss, ermöglicht eine einfache Längenanpassung der Riegelstange, die beispielsweise einen länglichen Grundkörper aufweist, an dessen Enden einerseits der erste Endabschnitt mit der Schließvorrichtung und andererseits der zweite Endabschnitt jeweils als separate Baueinheiten angeordnet sind. Für eine Anpassung der Länge der Riegelstange an die Maße eines jeweiligen zu sichernden Flügels können der Grundkörper dann nämlich einfach entsprechend abgelängt und die beiden Endabschnitte anschließend mit dem Grundkörper verbunden werden. Toleranzen in der Länge des Grundkörpers, die durch das Ablängen entstehen, können beispielsweise wiederum durch Montage der jeweiligen Verankerungselemente mittels Injektionsmörtel ausgeglichen werden.The fact that the locking device only has to cooperate with the first end section and that no further locking device has to be provided for the second end section enables a simple length adjustment of the locking bar, which has, for example, an elongated base body, at the ends of which the first end section with the locking device and on the other hand the second end section are each arranged as separate structural units. To adapt the length of the locking bar to the dimensions of a particular wing to be secured, the base body can then simply be cut to length and the two end sections can then be connected to the base body. Tolerances in the length of the base body, which result from the cutting to length, can in turn be compensated for, for example, by mounting the respective anchoring elements using injection mortar.
Gemäß einer alternativen Ausführungsform weist die Riegelstange wiederum einen dem ersten Endabschnitt bezüglich der Längsachse der Riegelstange entgegengesetzten zweiten Endabschnitt auf. Allerdings weist der zweite Endabschnitt anders als bei den vorstehend beschriebenen Ausführungsformen einen Kopplungsabschnitt auf, der in von dem ersten Endabschnitt weg weisender Richtung vorsteht, und dazu ausgebildet ist, in dem Kopplungszustand der Sicherungsvorrichtung in eine an einer Seite, vorzugsweise Unterseite, des Fensters oder der Tür ausgebildete Kopplungsaufnahme einzugreifen. Mit anderen Worten erfolgt bei dieser Ausführungsform die Kopplung des zweiten Endabschnitts der Riegelstange mit einem jeweiligen Verankerungselement gerade anders herum, als es bei dem ersten Endabschnitt der Fall ist. Denn anstelle einer Kopplungsaufnahme weist der zweite Endabschnitt einen vorstehenden Kopplungsabschnitt auf, der beispielsweise durch den Schraubenkopf einer in den zweiten Endabschnitt eingeschraubten Schraube gebildet sein kann.According to an alternative embodiment, the locking bar in turn has a second end section opposite the first end section with respect to the longitudinal axis of the locking bar. However, unlike in the above-described embodiments, the second end section has a coupling section which protrudes in the direction pointing away from the first end section and is designed, in the coupling state, of the securing device into a on one side, preferably underside, of the window or the Intervening door trained coupling receptacle. In other words, in this embodiment, the coupling of the second end section of the locking bar to a respective anchoring element takes place the other way round than it is is the case with the first end section. Because instead of a coupling receptacle, the second end section has a projecting coupling section, which can be formed, for example, by the screw head of a screw screwed into the second end section.
Somit braucht zur Befestigung des zweiten Endabschnitts auch kein Verankerungselement mit einem Kopplungsabschnitt vorgesehen zu werden. Stattdessen reicht es, an einer Seite des Fensters oder der Tür eine Kopplungsaufnahme vorzusehen, die in einem speziellen Verankerungselement ausgebildet sein kann, die aber auch direkt in der Laibung des Fensters oder der Tür oder auch in dem Boden unterhalb der Tür, etwa als eine Bohrung, eingebracht werden kann. Auf diese Weise kann zumindest an einer Seite des Flügels vermieden werden, dass ein Kopplungsabschnitt in den Bereich der Fenster- oder Türöffnung vorsteht. Diese Ausführungsform eignet sich daher insbesondere dann, wenn die Riegelstange senkrecht vor den Flügel einer Tür anbringbar sein soll. Denn so kann die Gefahr eines Stolperns über einen vom Boden nach oben vorstehenden Kopplungsabschnitt vermieden werden.It is therefore not necessary to provide an anchoring element with a coupling section for fastening the second end section. Instead, it is sufficient to provide a coupling receptacle on one side of the window or door, which can be formed in a special anchoring element, but which is also directly in the reveal of the window or door or in the floor below the door, for example as a hole , can be introduced. In this way it can be avoided at least on one side of the wing that a coupling section protrudes into the area of the window or door opening. This embodiment is therefore particularly suitable if the locking bar is to be attachable vertically in front of the wing of a door. This is because the risk of tripping over a coupling section projecting upward from the floor can be avoided.
Gemäß einer weiteren vorteilhaften Ausführungsform umfasst die Riegelstange einen, vorzugsweise zumindest teilweise hohl ausgebildeten, Grundkörper, wobei der erste Endabschnitt und gegebenenfalls der zweite Endabschnitt der Riegelstange durch von dem Grundkörper separat ausgebildete Endelemente gebildet werden, die auf den Grundkörper aufsetzbar sind. Wie vorstehend bereits beschrieben ermöglicht eine solche Ausbildung eine einfache Längenanpassung der Riegelstange durch Ablängen des Grundkörpers. Der Grundkörper kann insbesondere rohrförmig ausgebildet sein und als Material beispielsweise Edelstahl oder ein anderes festes und vorteilhafterweise korrosionsbeständiges Metall umfassen. Die Aufsetzbarkeit der Endelemente ist nicht darauf eingeschränkt, dass die Endelemente lediglich von außen an dem Grundkörper angeordnet werden können. Vielmehr können die Endelemente, insbesondere bei hohler Ausbildung des Grundkörpers, auch zumindest teilweise in den Grundkörper einsetzbar sein, z.B. durch Einstecken in die Enden des Grundkörpers.According to a further advantageous embodiment, the locking bar comprises a base body, which is preferably at least partially hollow, the first end section and optionally the second end section of the locking bar being formed by end elements which are formed separately from the base body and can be placed on the base body. As already described above, such a design enables simple adjustment of the length of the locking bar by cutting the base body to length. The base body can in particular be tubular and can comprise, for example, stainless steel or another solid and advantageously corrosion-resistant metal as the material. The placement of the end elements is not limited to the fact that the end elements can only be arranged on the base body from the outside. Rather, the end elements, especially with a hollow design of the base body, can also be at least partially inserted into the base body, for example by inserting it into the ends of the base body.
Vorzugsweise umgreifen die Endelemente dabei Endkanten des Grundkörpers. Auf diese Weise können die Endelemente insbesondere Schnittkanten überdecken, die durch das Ablängen des Grundkörpers zumindest an einem Ende entstehen können. Dadurch wird nicht nur die Sicherheit vor Verletzungen durch die möglicherweise scharfen Schnittkanten verbessert, sondern es können auch schräge oder unsaubere Schnitte überdeckt und auf diese Weise ausgeglichen werden. Für eine besonders stabile Anordnung der Endelemente an dem Grundkörper überlappen die Endelemente im auf den Grundkörper aufgesetzten bzw. in den Grundkörper eingesetzten Zustand mit dem Grundkörper axial jeweils um zumindest etwa 3 cm, vorzugweise zumindest etwa 5 cm.The end elements preferably encompass end edges of the base body. In this way, the end elements can, in particular, cover cut edges that can arise at least at one end due to the cutting of the base body. This not only improves the safety against injuries from the possibly sharp cut edges, but also oblique or unclean cuts can be covered and compensated in this way. For a particularly stable arrangement of the end elements on the base body, the end elements overlap with the base body axially by at least about 3 cm, preferably at least about 5 cm, in each case in the state placed on the base body or inserted into the base body.
Gemäß einer weiteren vorteilhaften Ausführungsform ist die Riegelstange dazu ausgebildet, mit einer zur Längsachse der Riegelstange parallelen Seitenfläche flächig am Flügelrahmen des Flügels des Fensters oder der Tür anzuliegen. Bei der genannten Seitenfläche der Riegelstange handelt es sich insbesondere um eine Seitenfläche des vorstehend beschriebenen Grundkörpers der Riegelstange. Grundsätzlich kann auch eine vom Flügel geringfügig beabstandete Montage zweckmäßig sein, beispielsweise um den Flügel gegen ein vollständiges Öffnen zu sichern, aber ein Kippöffnen zuzulassen, etwa um lüften zu können, ohne die Riegelstange entfernen zu müssen. Eine besonders zuverlässige Sicherung des Flügels ergibt sich aber, wenn die Riegelstange unmittelbar mit ihrer Seitenfläche an dem Flügel flächig anliegt, da hierdurch jede Bewegung des Flügels aus der Flügelebene heraus blockiert wird. Vorzugsweise ist die Sicherungsvorrichtung daher für eine solche unmittelbare Anordnung geeignet ausgebildet. Dazu kann die Riegelstange beispielsweise einen mehreckigen, insbesondere rechteckigen, vorzugsweise quadratischen, Querschnitt aufweisen, der nicht nur zur Biegesteifigkeit der Riegelstange beiträgt, sondern durch den auch eine Seitenfläche gebildet wird, die sich vorteilhafterweise im Wesentlichen über die gesamte Länge der Riegelstange erstrecken kann und somit für ein flächiges Anlegen an den Flügel zur Verfügung steht.According to a further advantageous embodiment, the locking bar is designed to lie flat with a side surface parallel to the longitudinal axis of the locking bar on the casement of the casement of the window or the door. The mentioned side surface of the locking bar is in particular a side surface of the basic body of the locking bar described above. In principle, an assembly slightly spaced from the sash can also be expedient, for example in order to secure the sash against complete opening, but to permit tilting opening, for example in order to be able to ventilate without having to remove the locking bar. A particularly reliable securing of the wing results, however, if the locking bar rests flatly directly with its side face on the wing, since this blocks any movement of the wing out of the wing plane. The safety device is therefore preferably designed to be suitable for such an immediate arrangement. For this purpose, the locking bar can have, for example, a polygonal, in particular rectangular, preferably square, cross-section, which not only contributes to the bending stiffness of the locking bar, but also forms a side surface is, which can advantageously extend substantially over the entire length of the locking bar and is thus available for a flat application to the wing.
Gemäß einer weiteren vorteilhaften Ausführungsform umfasst die Sicherungsvorrichtung zumindest zwei, vorzugsweise gleichartig ausgebildete, Riegelstangen sowie zumindest ein Verankerungselement, das dazu ausgebildet ist, in einer Richtung senkrecht zur Flügelebene des geschlossenen Flügels des Fensters oder der Tür montiert zu werden, und das zur lösbaren Kopplung mit einem jeweiligen Endabschnitt der zwei Riegelstangen zwei, vorzugsweise gleichartig ausgebildete, Kopplungsabschnitte aufweist, die im montierten Zustand des Verankerungselements parallel zur Flügelebene in entgegengesetzte Richtung vorstehen. Durch die zwei Kopplungsabschnitte kann ein solches Verankerungselement mit zwei Riegelstangen gleichzeitig gekoppelt werden. Daher eignet sich ein solches Verankerungselement insbesondere als Zwischenstück zwischen zwei parallel, insbesondere fluchtend, ausgerichteten Riegelstangen. Ferner ist das Verankerungselement dazu ausgebildet, senkrecht zur Flügelebene montiert zu werden, also in der Regel senkrecht zu den am Flügel anliegenden Riegelstangen. Das ermöglicht es, das Verankerungselement an einem Mittelsteg zwischen zwei Flügeln eines mehrflügeligen Fensters oder einer mehrflügeligen Tür zu montieren. Dazu kann das Verankerungselement beispielsweise einen, insbesondere stiftförmigen, Montageabschnitt aufweisen, der in den Mittelsteg eingeschraubt oder gedübelt werden kann.According to a further advantageous embodiment, the securing device comprises at least two, preferably identical, locking bars and at least one anchoring element, which is designed to be mounted in a direction perpendicular to the sash plane of the closed sash of the window or door, and for releasable coupling with a respective end section of the two locking rods has two, preferably of identical design, coupling sections which, in the assembled state of the anchoring element, project parallel to the wing plane in the opposite direction. By means of the two coupling sections, such an anchoring element can be coupled to two locking bars at the same time. Such an anchoring element is therefore particularly suitable as an intermediate piece between two locking bars aligned in parallel, in particular in alignment. Furthermore, the anchoring element is designed to be mounted perpendicular to the sash plane, that is to say generally perpendicular to the locking bars resting on the sash. This makes it possible to mount the anchoring element on a central web between two wings of a multi-wing window or a multi-wing door. For this purpose, the anchoring element can have, for example, an assembly section, in particular a pin-shaped one, which can be screwed or dowelled into the central web.
Ein solches Verankerungselement kann aber nicht nur als Zwischenverankerung zwischen zwei Riegelstangen genutzt werden. Denn es müssen nicht zwangsläufig beide Kopplungsabschnitte eines solchen Verankerungselements zur Kopplung mit einer jeweiligen Riegelstange genutzt werden. Dadurch, dass die Montage senkrecht zu der Richtung erfolgt, in welche die Kopplungsabschnitte ausgerichtet sind, kann das Verankerungselement stattdessen auch dazu genutzt werden, an einer zur Flügelebene des zu sichernden Flügels parallelen Wand, in der sich das Fenster oder die Tür befindet, einen Kopplungsabschnitt für eine einzelne Riegelstange bereitzustellen (Wandaufsatzmontage). Die Befestigung erfolgt dann zweckmäßigerweise nahe am Fenster oder Tür, also weiterhin im Bereich der Laibung des Fensters oder der Tür, jedoch nicht in der senkrecht zur Flügelebene ausgerichteten Oberfläche der Laibung selbst, sondern in der umgebenden Wand. Ein Verankerungselement in der umgebenden Wand statt in der Laibung zu montieren, kann etwa erforderlich werden, wenn die Laibung für die Montage zu schmal ist.Such an anchoring element can not only be used as an intermediate anchoring between two locking bars. Because it is not necessary to use both coupling sections of such an anchoring element for coupling to a respective locking bar. Because the assembly is carried out perpendicular to the direction in which the coupling sections are aligned, the anchoring element can also be used instead on to provide a coupling section for a single locking bar on a wall parallel to the sash level of the sash to be secured, in which the window or door is located (wall-mounted installation). The attachment is then expediently close to the window or door, that is, still in the area of the reveal of the window or door, but not in the surface of the reveal itself, which is oriented perpendicular to the sash plane, but in the surrounding wall. It may be necessary, for example, to mount an anchoring element in the surrounding wall instead of in the reveal if the reveal is too narrow for assembly.
Grundsätzlich kann die erfindungsgemäße Sicherungsvorrichtung auch genutzt werden, um den Flügel einer Schiebetür oder eines Schiebefensters zu sichern, auch wenn dieser Flügel für ein Öffnen keine Bewegung senkrecht zu seiner Flügelebene vollziehen muss. Die Riegelstange wird dann vorteilhafterweise nicht quer vor den zu sichernden Flügel angebracht, sondern zwischen der in Öffnungsrichtung weisenden Schmalseite des Flügels und der Laibung, auf die der Flügel beim Öffnen zu geschoben wird. Bei einem Öffnungsversuch wird die Riegelstange dann axial beaufschlagt und sperrt die Öffnungsbewegung. Zum Anbringen der Riegelstange kann auf dieselbe Weise wie vorstehend beschrieben zwischen einem im Bereich der Laibung montierten Verankerungselement und dem ersten Endabschnitt der Riegelstange eine Kopplung erfolgen. Der zweite Endabschnitt kann zudem mit einem Verankerungselement an der genannten Schmalseite des Flügels gekoppelt werden.In principle, the securing device according to the invention can also be used to secure the sash of a sliding door or a sliding window, even if this sash does not have to make any movement perpendicular to its sash plane for opening. The locking bar is then advantageously not installed transversely in front of the wing to be secured, but between the narrow side of the wing pointing in the opening direction and the reveal, to which the wing is pushed when opening. When an attempt is made to open, the locking bar is then axially loaded and blocks the opening movement. To attach the locking bar, coupling can take place in the same way as described above between an anchoring element mounted in the region of the reveal and the first end section of the locking bar. The second end section can also be coupled to an anchoring element on the said narrow side of the wing.

Damit die Riegelstange 13 auch unter Krafteinwirkung den Flügel 15 zuverlässig sichert, ist sie an den beiden Enden ihrer Längserstreckung mit jeweils einem Verankerungselement 23 gekoppelt, das seinerseits mit einem Montageabschnitt 25 (vgl.

Ferner weist die Zylinderkopfschraube 35, die insbesondere nach DIN EN ISO 4762 ausgebildet ist, in der Stirnseite ihres Zylinderkopfes eine Eingriffsvertiefung 41 in Form eines Innensechskants auf. Durch die Umfangsverbreiterung 39 und die Eingriffsvertiefung 41 sind an dem Verankerungselements 23 Strukturen ausgebildet, die ein formschlüssiges Hintergreifen des Kopplungsabschnitts 29 in viele verschiedene Raumrichtungen ermöglichen, nämlich durch Eingreifen in die Eingriffsvertiefung in alle radialen Richtungen und durch Hintergreifen der Umfangsverbreiterung 39 in axialer Richtung (bezogen auf die Richtung, in die der Kopplungsabschnitt 29 vorsteht und die bei der gezeigten Ausführungsform einer Längs- und Symmetrieachse des Verankerungselements 23 entspricht).Furthermore, the

Die Endabschnitte 31, 33 weisen jeweils eine Kopplungsaufnahme 49 auf, in die der Kopplungsabschnitt 29 des jeweiligen Verankerungselements 23 aufgenommen werden kann. Die Kopplungsaufnahme 49 des ersten Endabschnitts 31 wird in radialer Richtung (bezogen auf die Längsachse L der Riegelstange 13) durch einen geschlossenen Umfangsabschnitt 51 begrenzt, der eine U-förmige Wand bildet, durch die der Kopplungsabschnitt 29 eines Verankerungselements 23 nicht hindurchgeführt werden kann. Dagegen bildet der in radialer Richtung durchlässige Umfangsbereich einen offenen Umfangsabschnitt 53 der Kopplungsaufnahme 49. Wie in den Schnittdarstellungen der
Am ersten Endabschnitt 31 der Riegelstange 13 ist ferner eine Schließvorrichtung 57 vorgesehen, mittels welcher der erste Endabschnitt 31 an dem jeweiligen Verankerungselement 23 verriegelt werden kann. Die Schließvorrichtung umfasst einen Blockierkörper 59, in den ein Schließzylinder 61 aufgenommen ist und der zwischen einer Verriegelungsstellung (

Die Riegelstange 13 kann somit zunächst mit ihrem zweiten Endabschnitt 33 axial auf das eine der in der Laibung 27 des Fensters 17 montierten Verankerungselemente 23 aufgesetzt werden. Anschließend kann die einseitig bereits gekoppelte Riegelstange 13 durch Einschwenken mit ihrem ersten Endabschnitt 31 radial auf das andere Verankerungselement 23 aufgesetzt werden, was beispielsweise von vorne, vorzugsweise aber (wie dargestellt) von oben erfolgt.The locking

In der gezeigten sperrenden Stellung steht die Kugel einem Einführen oder Entnehmen des Kopplungsabschnitts 29 des Verankerungselements 23 in die bzw. aus der Kopplungsaufnahme 49 entgegen. Allerdings kann die Kugel 65, wenn der Blockierkörper 59 (wie in
Wenn dann der Blockierkörper 59 in die dargestellte Verriegelungsstellung versetzt wird, blockiert er den Mitnehmer 69 an dessen der Kugel 65 entgegengesetztem Ende, so dass die Kugel 65 nicht länger zurückgedrängt werden kann und ebenfalls durch den Blockierkörper 59 in der sperrenden Stellung blockiert ist. Dadurch ist dann die Riegelstange 13 an dem Verankerungselement 23 verriegelt, da der Kopplungsabschnitt 29 die Kopplungsaufnahme 49 nicht mehr verlassen kann und die Riegelstange 13 somit nicht vom Verankerungselement 23 gelöst werden kann, ohne zuvor über die Schließvorrichtung 57 die Verriegelung zu lösen.If the blocking
Für den Fall, dass die Kugel 65 ihre sperrende Stellung noch nicht vollständig erreicht hat, wenn der Blockierkörper 59 eingedrückt wird, weist der Mitnehmer 69 eine Anlaufschräge 71 auf, gegen die der Blockierkörper 59 dann anläuft, wodurch die Bewegung des Blockierkörpers 59 zu einem axialen Versetzen des Mitnehmers 69 und der Kugel 65 in die sperrende Stellung abgeleitet wird. Ferner ist der Blockierkörper 59 durch eine weitere Feder 73 in die Freigabestellung vorgespannt, so dass zum Entriegeln der Riegelstange 13 lediglich der zugeordnete Schlüssel im Schließzylinder 61 der Schließvorrichtung 57 gedreht werden muss und der Blockierkörper 57 daraufhin automatisch in die Freigabestellung versetzt wird, wodurch die Kugel 65 für ein Versetzen aus ihrer sperrenden Stellung freigegeben ist.In the event that the

Damit die beiden Teilriegelstangen 13.1, 13.2 möglichst bündig aneinander anschließen, wenn sie mit dem Verankerungselement 23' gekoppelt sind, ist am Rand der Kopplungsaufnahme 49 des jeweiligen zweiten Endabschnitts 33 der beiden Riegelstangen 13.1, 13.2 in dem Endelement 45 eine Mulde 63 ausgebildet (vgl.

Dadurch, dass der zweite Endabschnitt 33 der Riegelstange 13 keine Kopplungsaufnahme 49 zum Aufnehmen eines Kopplungsabschnitts 29 eines Verankerungselements 23 mehr, sondern stattdessen selbst einen Kopplungsabschnitt 29 aufweist, kann die Riegelstange 13 mit dem zweiten Endabschnitt 33 in eine Bohrung, z.B. am Boden einer Fenstertür eingesetzt werden. Wenn die Riegelstange mit dem Kopplungsabschnitt 29 an ihrem zweiten Endabschnitt 33 in die Bohrung eingesetzt ist, verbleibt dann noch ein hinreichender Bewegungsfreiheitsgrad für ein Schwenken der Riegelstange 13, so dass die Kopplung des ersten Endabschnitts 31 anschließend wie ansonsten auch durch seitliches Aufnehmen eines Kopplungsabschnitts 29 eines Verankerungselements 23 in die Kopplungsaufnahme 49 des ersten Endabschnitts 31 erfolgen kann.Because the

Die Wandhalterung 89 weist eine Umfangsverbreiterung 39 sowie eine Eingriffsvertiefung 41 auf.
