Description

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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. 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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. 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

In Fig. 1 is an embodiment of a security device 11 according to the invention, the locking bar 13 is mounted transversely in front of the closed wing 15 of a window 17 to be secured and in this way locks the wing 15 against opening. The locking bar 13 is arranged such that it directly with the rear side surface of its base body 19, which is designed as a hollow tube with a substantially square cross-section and extends along the longitudinal axis L of the locking bar 13 over the entire length of the locking bar 13 abuts the sash frame 21 of the sash 15. In this way, the wing 15 is caught in its closed position substantially without play.

So that 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. There is essentially only one coupling section 29 beyond the reveal 27 (cf. Fig. 2 ) of the anchoring element 23 in the direction of the opposite side of the wing 15. 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.

In the Fig. 1 shown embodiment of the anchoring element 23 of the securing device 11 is in Fig. 2 shown separately. 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 part of the screw shaft protruding from the sieve sleeve 37 and the cylinder head, which represents a circumferential widening 39 with respect to the screw shaft, together form the coupling section 29 of the anchoring element 23. On the other hand, 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. As an alternative to such an attachment, depending on the material of the reveal 27, 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.

Furthermore, 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).

In Fig. 3 the same anchoring element 23 is shown together with the first end section 31 of the locking bar 13. Correspondingly shows 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. In the 4 and 6 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. Thus, in the coupling state, in which it is coupled to the permanently attached anchoring elements 23, the locking bar 13 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. In contrast, the radial region which is permeable in the radial direction forms an open peripheral section 53 of the coupling receptacle 49. As in the sectional views of FIG 7 and 8 can be seen more clearly, 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.

At the first end section 31 of the locking bar 13, 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. To adjust, 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. For a reverse adjustment from the locking position into the release position, on the other hand, actuation by means of a key assigned to the locking cylinder 61 (in Fig. 3 not shown) required.

In contrast to the coupling receptacle 49 of the first end section 31, that in FIGS 5 and 6 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.) In addition, 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.

In the sectional views, 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.

In the blocking position shown, the ball prevents insertion or removal of the coupling section 29 of the anchoring element 23 into or out of the coupling receptacle 49. However, if 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. Thus, the coupling section 29 can be made from the in Fig. 8 position shown are inserted into the coupling receptacle 49. When the coupling section 29 is completely received in 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.

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.

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.

The Fig. 9 and 11 show alternative embodiments of the security device 11 according to the invention, which are suitable for double-leaf windows 17 '. Already due to the width of multi-leaf windows 17 ', it may be expedient for a higher reliability of the security to provide 27 additional anchoring points along the locking bar 13 in addition to the anchoring points in the area of the reveal.

In the embodiment according to Fig. 9 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. 10 Anchoring element 23 'shown, however, 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.

In order that the coupling sections 29 protrude far enough from the central web 75 perpendicular to the mounting section 25, 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 ).

In the embodiment according to 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.

In 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. However, in the present embodiment, 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 ). To determine the screw-in depth, a screw sleeve 85 is also provided, which surrounds the screw shaft below the screw head. By screwing in the cylinder head screw 35, the second end section 33 can thus be converted from an end section with coupling receptacle 49 into an end section with the above coupling section 29 as required.

Because the second end section 33 of the locking bar 13 no longer has a coupling receptacle 49 for receiving a coupling section 29 of an anchoring element 23, but instead has a coupling section 29 itself, 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.

In 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. In addition, 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.
