Description

The invention relates to a lock for wing systems, in particular for sliding door systems. The DE3427609 discloses all features of the preamble of claim 1.

Latches of the aforementioned type are known per se. In the DE 198 37 193 A1 a locking latch for tilt windows is shown. Serving as a locking element guide pin is taken in a translucent guided in a slot of a corresponding longitudinal guide and further attached to a scissor arm of a tilting fitting of an associated window sash. The slot ends at one end in an end limit, which has the shape of a circular hole whose diameter is larger than the slot is wide. The longitudinal guide is elastic. Therefore, it is the guide pin possible to be moved along the slot and locked in the circular hole, whereby the locking or wing detection is achieved. The disadvantage is that the lock is constantly effective. Furthermore, the guide pin rubs constantly in the slot, resulting in an increased force when moving the guide pin in the longitudinal guide and wear. In addition, the lock can be lifted only by moving the guide pin out of the slot out. An unlocking for explicit release of the guide pin and thus the tilting window is not present.
From the DE 10 2004 060 124 A1 a sliding door lock is known in which a kind of locking bell is arranged rotationally fixed to a drive pulley of a sliding door drive. To the drive pulley, an endless traction means of the sliding door drive is performed. The bell instructs a preferably circumferentially formed, extending parallel to the axis of rotation of the bell wall recesses. A locking bolt can be translationally moved transversely to the axis of rotation towards the recesses and engaged with a respective one of the recesses. This prevents rotation of the bell. As a result, the drive disk no longer rotates and thus the sliding door wings which are effectively coupled with the traction means can no longer be moved. The disadvantage of this solution is that rotating parts must be present in order to accomplish the locking can. An application, for example, to other door systems is hard to realize. In addition, the structure is relatively large and complex.
The object of the invention is to counteract the aforementioned disadvantages.

This object is solved by the subject matter of claim 1. Advantageous developments of the invention are specified in the subclaims.
A device according to the invention for locking at least one wing of a wing system has a first locking element and a second locking element. The first locking element comprises at one end a first latching element. The second locking element comprises at a first locking element facing the end of a second locking element. This second latching element is designed to be latchingly engaged in the locking position with the first latching element. The second locking element is also adapted to be fixed in relation to the wing system. The first locking element, however, is arranged to be arranged with respect to the at least one wing such that the first locking element upon movement of the at least one wing with this Movement is correspondingly moved such that the first locking element is moved depending on the direction of movement of the at least one wing translationally in a locking position on the second locking element to or in an unlocked position of the second locking element. Ie. the first locking element is also moved due to a wing movement, whereas the second locking element remains in one and the same place with respect to the entire wing system. One of the locking elements also includes an activation element that allows the latching operative engagement between the first locking element and the second locking element according to a locking position or prevented according to a release position upon actuation. Ie. the activation element causes an arming or switching off the wing lock thus formed. The translational movement of the first locking element makes it possible to integrate the locking device in any type of wing system, which has a translationally moving part, which is moved by the respective wing, or which is otherwise capable of, via the wing movement a part translatorisch (to move). This solution is thus completely independent of the type of any existing Flügelbetätigers who is able to move the respective wing in at least one direction. Ie. This solution can also be used in purely manually operated wing systems. In addition, this solution is easy to integrate in wing systems.

Preferably, the second locking element is designed to be fixedly mounted in the region or in a receiving groove of a stationary with respect to the wing system or the respective wing arranged guide member. This allows easy integration of the second locking element. It is in fact possible, simply insert the first locking element in the receiving groove translationally movable. It can then assume the function of a slider, for example. This results in the advantage that the space required for the locking arrangement thus formed can be kept to a minimum.

The first or the second latching element has a latching projection, according to which the respective other latching element has a locking part corresponding to this latching projection. Suitable locking parts are in turn a latching projection or a recess.

The latching part comprises a first pass-through part which has a recess which serves for the latching explained below. Pass-through part means that the latching projection for the purpose of locking said wing passes through this latching recess. The latching recess is formed continuously in the first pass-through part. It is also movable at a right angle to the translatory movement path of the latching projection such that the latching recess is arranged in the release position so that the latching projection can move along its translatory movement path through the latching recess. It is so arranged in blocking position so that the locking projection, if he engages in the locking position, the recess is prevented from moving from the first recess towards locking element at least to a predetermined extent and thus latching with the locking recess engages behind is in operative engagement. The latching recess extends along the direction of movement of the second locking element, that is to say in the direction of the latching projection, so that it can move through the latching recess with a certain extent and thus be able to pass through it. The Locking recess is arranged in the release position so that the locking projection along its translational movement path can freely move back and forth through it. According to the invention, the latching part further comprises a second pass-through part, which is arranged on a latching projection facing side of the first pass-through part. It likewise has a recess, similar to the first penetration part, which recess is continuous in the second penetration part. It is stationary in relation to the second locking element arranged such that the locking projection along its translational movement path through the recess can move freely back and forth. Ie. this recess is not the lock but for example as a stop for the first locking element. In the blocking position, the recesses of the Durchgriffsteile are thus arranged to each other that the locking projection, if he passes through both recesses, is prevented from moving from the recess to a recess in the direction of the second passage portion at least to a predetermined extent and thus detent with the latching recess is in operative engagement. Ie. the recesses take each other different positions in release and blocking position. By this measure, it is possible, the release or locking of the locking projection exclusively by means of two very simple and inexpensive to manufacture structures, for example by means of through holes as recesses, form.

Preferably, the pass-through parts abut each other. This has the advantage that the second penetration part can serve as a support for the first penetration part and thus increases the locking action of the aforementioned locking projection and the locking stability of the first locking element.

Preferably, the recess of the respective penetration part has a, seen in the direction of movement of the latching projection, to the outer contour ebenjenen latching projection substantially complementary inner contour.

The penetration parts preferably each have a portion which extend parallel to each other and are plate-like. The plate-like design of the Durchgriffsteile allows, seen transversely to the direction of movement of the locking projection, a very economical space utilization.

If the plate-like sections also still abut each other, the second locking element, seen along the direction of movement of the locking projection, is very short and thus saves space.

The latching projection is preferably tapering at its end facing the latching recess in the direction of the latching recess, and is furthermore preferably mushroom-shaped. This makes it possible to push the locking projection through the recesses of the Durchgriffsteile through to the aforementioned operative intervention, even if they are already in the locked position. The latching projection can also be designed so that the latching projection can be moved out of the latching recess by overcoming the locking or locking force produced by the operative engagement with the latching recess and also in the opposite direction of movement. Ie. With such a locking projection is a very simple and inexpensive way a wing lock with overload protection feasible.

The aforementioned activation element is preferably formed by means of an electromagnet which, when actuated, the first penetration part in Release or moved in locked position. The electromagnet has the advantage of defined working positions (locking, unlocking) of the locking arrangement and can also be easily adapted via the energization of desired holding or locking forces. For example, pulsed current can be used.
Preferably, at least one of the locking elements on a side facing the respective other locking element on a stop for the respective other locking element. This is easily a limitation for the locking projection during its movement in the direction of corresponding locking element feasible.

The second locking element is adapted to be fixed in relation to a guide or slide rail of the wing system. The first locking element can also be accommodated in the guide or slide rail directly or indirectly in a translatory manner on the second locking element to and away from it. This allows an elegant and in the extreme case completely invisible integration of the second locking element using the already existing guide or slide rail. Thus, parts of already existing wing systems are used. Furthermore, this results in both space-technical and optical advantages, since the second locking element can be hidden optically.

The second locking element is adapted to be fixedly mounted on or in the guide or slide rail. This has the advantage that only on or in this rail appropriate mounting options must occur. In addition, no edits are necessary on the wing or other parts of the wing system, on the one hand the assembly or retrofitting facilitates, on the other hand, but also allows a visually-traced decommissioning. The wing system thus has at least one movable wing, at least one with respect to the wing system or the at least one movable wing fixedly arranged guide or slide rail with a receiving groove and at least one of the above-described locking devices.
The wing system preferably comprises at least one wing designed as a pivoting wing. This wing is operatively connected via a slide linkage with a Schwenkflügelbetätiger, so a swing door drive or door closer. Ie. the wing system has a slide, in which a slider is added translationally guided, which in turn is freely rotatably articulated on the sliding arm of the linkage. The first locking element may be part of or replace the slider.
Alternatively or additionally, the wing system has at least one wing designed as a sliding (door) wing. Such wings are usually suspended above the respective wing arranged support and / or guide rails or guided along their path of movement. In the context of the invention, the mounting rail can thus additionally serve for the direct or indirect guidance of the second locking element, for example via a carriage operatively connected to the wing. Ie. Also in sliding systems such as sliding doors, folding doors, partitions and the like, the above-described locking arrangement is very simple and preferably invisible to the user integrated.

Further features and advantages of the invention will become apparent from the following description of preferred embodiments.

FIG. 1 shows a locking arrangement 1 according to an embodiment of the invention. The arrangement 1 comprises by way of example a mounting rail 10 of an exemplary sliding door system. The sliding door system is linear motor based in the example shown. The support rail 10 is used in the example shown in a receiving portion 11 at least the inclusion of a stator, not shown here of the linear motor. Another, separately formed receiving portion 12 is mainly used for guided recording preferably of carriage 20 one here not shown sliding sash. The sliding sash is received in the support rail 10 via aforementioned carriages 20.

For this purpose, the carriage 20 by way of example a receiving profile 21, the down, d. H. towards the wing, open. This opening serves to carry out a respective driver 23, which actively connects the receiving profile 21 with said wing. In the receiving profile 21, a rotor 22 is used, which has a series of permanent magnets in the example shown. The rotor 22 enters the stator in a known manner in magnetic interaction.

At the left end of the carriage 20 and its receiving profile 21, a locking member 30 is fixedly mounted. Preferably, the locking element 30 is attached by means of a stop portion 31 on the front side or in the profile 21. On the side facing away from the profile 21, a shaft 33 connects to the stop portion 31, at the free end of a preferably plizkopfartiger locking projection 32 is formed. Ie. the locking projection 32 tapers in the direction of its free end. The shaft 33 has a smaller diameter than a maximum outer diameter of the latching projection 32. Stopping section 31, shaft 33 and latching projection 32 are fastened to each other or formed integrally in part or in the entirety.

Preferably, in the region of the left end side of the support rail 10 is a locking element 100. The locking element 100 has a mounting portion 102 which is received, for example, by clamping in the support rail 10 and in its receiving portion 12. However, all other mounting options such as screws, locking, welding, gluing and the like are conceivable.

FIG. 2 shows the locking arrangement 1 of FIG. 1 in section along a line A - A in FIG. 1 ,

The locking element 100 comprises two so-called pass-through parts 110, 120. The function of these parts will be explained later. The penetration part 110 preferably has centrally a recess 111, which is formed in the example shown as a circular through hole and extends along the direction of movement of the locking projection 32, ie here along the longitudinal extent of the support rail 10 and the profile 20. The penetration part 110 is transversely to the direction of movement of the locking projection 32 and the carriage 20, ie obliquely to the bottom right in FIG. 2 , guided translationally movable.

At the end remote from the latching projection 32, the locking element 100 also has an activating element here in the form of an electromagnet 101. The electromagnet 101 interacts magnetically with a here partially visible armature plate 113 of the penetration part 110. The electromagnet 101 is arranged so that it attracts the armature plate 113 obliquely to the bottom right transversely to the direction of movement of the locking projection 32 and along the direction of movement of the penetration part 110 when energized.

The anchor plate 113 is fixed to the penetration part 110 or formed integrally with it. Penetration part 110 and anchor plate 113 preferably include an angle of about 90 °. Ie. the penetration part 110 is moved obliquely down to the right as soon as the electromagnet 101 attracts the anchor plate 113 during energization.

The attachment of the locking element 100 by means of the aforementioned, fastening portion 102, which is preferably clamping in the Support rail 10 is added. However, all other mounting options such as screws, locking, welding, gluing and the like are conceivable. The solenoid 101 is fixedly attached to the mounting portion 102 by means of screws 105, one of which is visible.

The locking arrangement 1 is shown in a so-called locking position. Ie. the latching projection 32 is engaged with the through-engagement parts 110, 120 and engages behind the passage portion 110. As can be seen, the latching projection 32 and therefore also the shaft 33 pass through the passage portions 110, 120 or their recesses 111, 121, of which only here the recess 111 of the penetration part 110 is clearly visible. Ie. the passage portions 110, 120 are arranged between locking projection 32 and abutment portion 31.

The illustrated block arrow represents the direction of movement of the rotor 22 or of the carriage 20 and thus of the locking element 100 and the latching projection 33. Thus, the carriage 20 connected thereto is prevented from disengaging from the locking element 100, ie obliquely to the bottom left in FIG FIG. 2 to move. As a result, of course, the operatively connected to the carriage 20 wings also prevented from moving and thus locked.

The stopper portion 31 is preferably in the position shown on the press-through member 120 at. However, it can also be provided that the shaft 33 is longer, so that the stopper portion 31 can move away from the penetration part 120 by a certain distance. This has the advantage that, for example, caused by temperature fluctuations changes to the system can be compensated.

Further, the receiving portions 11, 12 are shown here for the profile 21 and the stator of the linear motor, also not shown here. The receiving portions 11, 12 are separated by means of mutually facing, protruding projections 13 on or in the mounting rail 10 from each other. The wings facing away from the surfaces of the projections 13 serve as a support surface for the stator. The wings of the facing surfaces of the projections 13 are preferably used as a support surface for the mounting portion 102 of the locking element 100. In addition, the projections 13 on its profile 21 facing surfaces can serve as a running surface for non-visible rollers of the carriage 20. This is particularly useful because it ensures that between rotor 22 and recording profile 21 and stator is always maintained a predetermined distance, so that the magnetic driving force of the linear motor thus formed is ensured. At the side facing the wing, not shown, the support rail 10 also has projections 14, which are similar to the projections 13 facing each other protruding. The projections 14 may also serve as a running surface for corresponding rollers of the carriage 20 on their sides facing away from the wing. The projections 13, 14 are thus preferably used to position the respective carriage 20 in the mounting rail 10th

FIG. 3a shows the locking member 100 in more detail and according to a first embodiment of the invention. The locking element 100 is shown in a so-called locking position, which allows the aforementioned locking position. The anchor plate 113 has a pin-like part 114. The part 114 is preferably formed through the anchor plate 113 therethrough. This makes it possible, for example, to arrange a helical spring 106 as a restoring element between armature plate 113 and electromagnet 101. The return spring 106 causes, when the solenoid 101 is not energized, that the armature plate 113th is moved to a release position, which is not shown here. In addition, the part 114 can be used at its end remote from the electromagnet 101 for connection of an actuating element, such as a Bowden cable, a lever, a pull rod or the like. This makes it possible to use the locking element 100 and the locking assembly 1 also in the context of a closing sequence control in a two-leaf swing door system. In that case, the solenoid 101 serves to hold the stationary leaf of this system. To release the locking projection 32, the part 114 is pulled by means of the aforementioned actuating element from the other wing, ie the active leaf, or by its actuator in the release position, in which the recesses 111, 121 are preferably aligned.

As can be seen, the fastening section 102 and the penetration part 120 form a type of mounting bracket, to which the electromagnet 101 is fastened here by means of screws 105 on an inner side facing the wing. In the example shown, the passage portions 110, 120 have circular recesses 111, 121 which are not aligned with one another in the illustration shown. In the aforementioned release position, however, the recesses 111, 121 are aligned with each other, so that the locking projection 32 can move freely through the recesses 111, 121 and thus can not be locked or locked. Thus, the locking element 100 is in the aforementioned release position.

If a locking of the aforementioned locking projection 32 is desired, the electromagnet 101 is energized, the armature plate 113 magnetically attracted and thus the penetration part 110 in the in FIG. 3a shown position moves. The aforementioned, tapered design of the locking head or locking projection 32 allows in this position that this overcome both the recess 121 and the recess 111 can and can engage with the recess 111 latching into engagement. Ie. the locking projection 32 engages in the locking position due to the mismatched arrangement of the recesses 111, 121 to each other, the recess 111 and can not or only to a small extent in the direction out of the recesses 111, 121 are moved. This creates a very simple, yet effective locking of the connected wing / s.

FIG. 3b shows the locking element 100 in the release position. As can be seen, the recesses 111, 121 of the passage portions 110, 120 are aligned with each other. At least they are aligned with each other so that the locking head 32 is not shown, preferably without resistance through the recesses 111, 121 can be freely moved back and forth. In that case, the electromagnet 101 is preferably not energized. The return spring 106, not shown, presses the penetration part 110 in the illustrated release position.

The electromagnet 101 can, as shown, be designed to be normally open or the latching projection 32 to be releasing. But it can just as well normally closing and thus locking projection 32 may be formed locking in the locked position. In that case, the recess 111 in the in FIG. 3a shown working position of the electromagnet 101, that is, when it has magnetically attracted the armature plate 113, formed so that it is aligned with the recess 121. If the energization of the electromagnet away, the armature plate 113 is urged away from the electromagnet, and the recesses 111, 121 are increasing FIG. 3a similar alignment to each other, so no longer aligned with each other.

FIG. 4a shows a locking element 100 according to a second embodiment of the invention. The attachment portion 102 is in cross section U-shaped and thus provides a receiving space for the electromagnet 101. The solenoid 101 is preferably mounted by means of screws 105 on the mounting portion 102. A wall portion connecting the two limbs 108 of the U is formed by the pass-through portion 120, which is thus embodied here as an example in one piece with the fastening portion 102. The legs 108 have on their sides facing each other guide portions 107 here in the form of protruding, mutually open guide grooves or rails on. In these guide portions 107, the pass-through part 110 is movably guided between locking and release position, in this case into and out of the plane of the page.

On the side facing away from the legs 108 of the passage member 120, two in the direction of the electromagnet 101 away, claw-like looking clamping portions 109 close. Ie. Each clamping portion 109 has a first wall portion 109a, which extends from the penetration portion 120. At the end of the wall portion 109a facing away from the passage portion 120, a respective second wall portion 109b follows, which preferably encloses a right angle with the associated wall portion 109a. At the end of the second wall section 109b facing away from the first wall section 109a, a respective third wall section 109c, which extends in the direction of the penetration section 120, adjoins.

The clamping portions 109 are preferably parallel to each other. The wall portions 109a, 109c of the clamping portions 109 are formed so that the locking element 100 can be inserted into the receiving portion 12 of the support rail 10, not shown. In this case, facing away from each other surfaces 109d, 109e of the wall sections 109a, 109b each correspond to a corresponding one of the projections 13, 14 of the mounting rail 10.

Each wall section 109b has an unillustrated passage opening, through which a bracing element is guided here in the form of a respective screw 104. The wall portions 109a, 109b of a respective clamping portion 109 have at least partially a distance a, which is smaller than a maximum outer diameter of the screw 104. The screws 104, however, are designed so that they are screwed in the direction of solenoid 101 between the aforementioned areas of the associated Wall sections 109a, 109b with distance a to each other. At this time, the third wall portion 109c is moved away from the wall portion 109a of the respective clamp portion 109, so that the distance a increases. The surfaces 109c, 109d said clamping portion 109 engage with the projections 13, 14 by clamping in abutment; the locking element 100 is clamped or jammed in the support rail 10.

The locking element 100 thus forms a kind of module that can be used as a whole in the support rail 10.

Instead of screws 105 can each also find a Aufspreizstift use.

FIG. 4b shows the locking element 100 from a different perspective. Here, in particular, the screws 105 for fastening the electromagnet 101 on the attachment portion 102 can be seen.

Preferably, both surfaces 109d, 109e, in turn, preferably both clamping portions 109 and the corresponding wall portions 109a, 109c have groove portions 109f, whose unspecified grooves extend transversely to the insertion direction in the support rail 10, not shown. If the clamping surface of the facing, associated projection 13, 14 of the mounting rail 10 facing the respective surface 109d, 109e has essentially complementary grooves, the locking element 100 can be gradually moved into the final insertion position in the mounting rail 10 and thereby fixed (before) which simplifies assembly.

FIG. 5 shows a locking element 100 according to a third embodiment of the invention in the locked position. The recesses 111, 121 are therefore not aligned with each other. The penetration part 110 is movably supported by means of elongated holes 112 via guide pins fastened or integrally formed on the penetration part 120 as guide section 107 along the actuation direction of the electromagnet 101. The anchor plate 113 and the penetration part 110 preferably form an L-shaped part. The pins 107 pass through corresponding elongated holes 112 of the penetration part 110. The elongated holes 112 thus extend along the direction of movement of the penetration part 110.

As can also be seen, in the region of the penetration part 110, securing washers 103 are mounted on the guide pins 107. They prevent the penetration part 110 from the penetration part 120 or the attached thereto or integrally formed with this guide pins 107 in the direction of solenoid 101 removes or dissolves. However, other solutions such as snap rings, lock nuts and the like are possible. In the latter case, the guide pins 107 have correspondingly formed screw threads.

Ie. the penetration part 110 is movably mounted on the attachment portion 102, so that the operative connection with the electromagnet 101 likewise fastened to the attachment portion 102 is freed from the weight of the penetration member. Thus, the operative connection via the anchor plate and the connecting part 114 can be done very easily.

As solenoid 101 is preferably a solenoid used. Alternatively or additionally, the electromagnet 101 is formed bistable, so that it accomplishes both the blocking and the release position of the locking element 100. In that case, additional return elements can be omitted.

The part 114 can also be used in connection with a mechanical release part in the context of an exemplary single-leaf door, for example for an emergency opening or emergency closing of the connected wing. Emergency opening or closing means that an opening or closing of the respective wing / s must be possible if the power supply of the wing system, ie in particular the locking arrangement 1, is eliminated.

As explained above, the locking projection 32 is in the blocking position on the locking element 100 facing away from the surface of the recess 111 of the remote with respect to the locking element 30 penetration portion 110, thus engages behind them and thus locks the connected wing. The pass-through part 120 arranged between carriage 20 and pass-through part 110 supports the pass-through part 110 in the direction of carriage 20, thus serving to ensure the locking.

Since the latching projection 32 engages behind the transverse to the direction of movement of the latching projection 32 movable passage portion 110, the electromagnet 101 in the locked position do not counteract the inertial forces of the connected or the wing. He has only to apply the force required to hold the locking projection 32 in engagement, so the force to hold the recesses 111, 121 in the position not aligned. This power is for a much lower. On the other hand, this force does not or only insignificantly depends on the weights of the connected wing / s.
As a result, a universally deployable lock for wing systems of any kind is provided by the invention, which have a with the / n to be locked wing / n operatively connected guide or slide / n, which are thus in operative connection with this / n wing / n. Since only guide or slide rail / s are required, the lock can be independent of the respective drive mechanism of the wing system.
The invention is not limited to the embodiments described above. It can for example be applied to any type of sliding sash systems such as sliding door systems and the like. Furthermore, it is readily applicable to swing leaf systems, provided they are provided with a slide, for example, as part of a slide linkage. Further areas of use are, for example, windows, which are also guided on a slide rail guided by a so-called scissor arm.

Of course, any other cross-sectional shape is possible instead of the circular cross-sectional shape of the recesses 111, 121. The cross-sectional shapes The recesses 111, 121 need not be complementary to a seen along the movement of the locking projection 32 cross-sectional shape of the locking projection 22 and not be identical to each other. For example, they can be square. Due to the non-alignment with each other of the recesses 111, 121 in the locked position of the locking projection 32 is still locked to the recess 111 at. The recess 121 of the passage member 120 is aligned in the mounting position at all times with the locking projection 32, so that it is always able to pass the recess 121 without resistance can.
The locking elements 30, 100 can be arranged interchanged, so that now the locking element 100 with the carriage 20, but in any case in accordance with a movement of the connected wing, is moved.
In the figures, a locking arrangement 1 is shown, in which at one end of the support rail 10, a locking element 100 is arranged. By way of example, the position of the wing locked by means of the locking arrangement 1 corresponds to a closed position of this wing. Alternatively or additionally, a further locking arrangement may be provided which is arranged in the mounting rail 10 in such a way that it locks said wing in the open position, ie serves as an open-holding device. This is useful, for example, for shops whose front door should remain open to the public.
According to FIGS. 1 and 2 the locking element 30 is placed on the front side of the receiving profile 21. But it can be just as well trained be used analogously to the locking element 100 with respect to the support rail 10 in the receiving profile 21 or inserted.

Instead of an electromagnet 101, for example, a motor with drive pinion can be used, which meshes with a rack, which is preferably part of the penetration part 110. This can be changed purely motor between release and blocking position. Furthermore, manual or other automatic adjustment options for the change between locking and release position are possible.
