Description

DESCRIPTION

Enervation arrangement for a double leaf door

^{The invention relates to an arrangement Jan} r ^{vamiento for double doors of the type mentioned in the} preamble of claim 1 and a corresponding double leaf door with such locking arrangement.

Double-leaf doors with an active leaf and a passive leaf, as well as an interlocking arrangement with an integral panic function, in the closed state must be able to be opened safely even when the passive leaf is first opened.

To prevent the open active leaf closing latch from tilting on a passive leaf closing plate, the closing latch is moved from the open position to a closed position by actuating a latch and / or panic bar on the passive leaf by means of a special mechanism in the passive leaf counter box. Previously, a locking latch lock is released by actuation of an unlocking element, which is generally integrated into the locking latch. Since such doors have different gap dimensions due to manufacturing, the distance between a lock plate of the counter box and a lock front of a lock box and, therefore, a depth of penetration of the lock latch in a corresponding recess in the closing plate, it can vary. Therefore, the unlocking mechanism is in the counter box, which is made adjustable to the unlocking element in order to be able to adjust a common actuation path of the unlocking mechanism in the counter box and of the closing latch and the unlocking element and to allow unlocking of the interlocking device, even with different gap measures. It is known from the state of the art to compensate the different gap measures by means of compensation plates, which requires some experience and a certain amount of time. Furthermore, compensation is possible only in large steps.

From WO 2010/016074 A1 is known for example a universal lock for swing doors with a box-like body comprising a movement cylinder, a rotary sleeve, suitable lever systems, a bolt and a stem. The bolt is locked in the open position when the stem also protrudes. If the stem is retracted by an external force, the bolt is released. Other means are provided for mechanical deactivation.

DE 102009003860 B4 discloses, for example, an anti-panic lock with a latch which can be advanced and delayed in a direction of movement of the latch, in particular by a closure member of a closing cylinder, which is held in the forward position. by means of a latch and which has a trigger that can be moved in a direction of movement of the latch, which in the event of a displacement caused by the impulse of its front edge in the direction of return of the latch releases the latch to allow a rearward movement of the latch. The latch forms in the area of its front an open niche towards the front of the latch flanked by its front surface, in which the trigger is located, so that the niche is open on both wide sides of the latch and the front edge for the release of the hook must be displaced inside the niche by the edge located in the front of the latch, so that the front edge of the trigger is located in the niche when the hook is released.

The invention has for its object to indicate an interlocking arrangement for a double-leaf door and a corresponding double-leaf door, which allow an intuitive and easy-to-adapt adaptation of an unlocking mechanism to a current gap measurement.

This object is achieved by the characteristics of the interlocking arrangement for a double leaf door according to claim 1 and by the characteristics of the double leaf door according to claim 13.

Advantageous embodiments and refinements of the invention are specified in the remaining claims.

The embodiments of an interlocking arrangement according to the invention for a double-leaf door comprise, respectively, a lock box with a lock front and a latch latch and a lock that secures the latch latch in an open front state. to a transfer to a closed state and a counter box with a closing plate. The closing latch in the open state is applied at least partially in a recess in the closing plate, so that for the performance of an anti-panic function a drive device in the counter box actuates a guided release element in the closing latch , which lifts the latch latch lock on the lock case and transfers the latch latch from the open state to the closed state, where the latch latch releases the latch plate. According to the invention, the unlocking element has an adjustment device accessible from the lock front, which in the open state adjusts a gap width between the actuation device and an actuation region of the unlocking element.

Due to the possibility of adjusting the unlocking element, the gap width between the actuating device and the unlocking element can be advantageously adapted intuitively to the size of the current gap, the actuation region of the unlocking element being moved by the adjusting device in the direction of the actuating device when the current gap measurement is greater than a nominal gap measurement and the closing latch does not penetrate as deeply into the counterbox. Further, the actuation region of the unlocking element can be moved away from the actuation direction by a corresponding opposite movement, if the current gap dimension is less than the nominal gap dimension and the closing latch penetrates deeper into the counterbox. In this way it is advantageously possible to adjust a common actuation path of the actuation device with the closing latch and the unlocking element and, thus, to adapt a current gap measurement between the counterbox and the lock box, in such a way that the unlocking of the interlocking device is ensured in case of panic. Due to the accessibility of the adjustment device from the front side, adjustment can be carried out very easily. Since at the same time the actuation device is not influenced by the adjustment of the actuation region, advantageously no additional adjustment measures are required in the counterbox for adaptation to the gap measurement.

Furthermore, a double-leaf door with an active leaf and a passive leaf and an interlocking arrangement of this type is proposed, comprising a lock box with a front lock and a closing latch and a lock that secures the closing latch. in an open state versus a transfer to a closed state, and a counter box with a closing plate. In this case, the closing latch in the open state is applied at least partially in a recess in the closing plate. To perform an anti-panic function, an actuation device in the counter box actuates a guided unlocking element in the closing latch, which lifts the locking of the closing latch in the lock box and transfers the closing latch from the open state to the closed state, in which the closing latch releases the closing plate and the door is unlocked.

According to the invention, the actuation region is arranged on an outer part of the unlocking element, which is arranged so that it can be moved axially towards an inner part of the unlocking element. Furthermore, the distance between the inner part and the outer part and the gap width between the driving device and the driving region can be adjusted by means of a screw element that can be screwed into a first threaded hole in the inner part and a second threaded hole on the outside. The screw element can preferably be made as a captive screw. By means of said screw connection and accessibility from the front side, a very exact adjustment or a fine adjustment of the distance between the inner part and the outer part or the gap width between the actuating device and the actuating region is advantageously possible. . As a result, a simple and quick adaptation of the unlocking mechanism in the closing latch to the current gap between the counterbox and the lock box is advantageously possible.

In an advantageous embodiment of the locking arrangement, the actuation device can comprise a tilting lever, which can be tilted about a tilting axis between a starting position and an ending position. Furthermore, the rocker lever can comprise several legs. Thus, the tilting axis can be arranged, for example, in the region of the free end of a first leg. A second leg can be coupled to an adjusting mechanism in the free end region, and at least one actuating element can be provided in the free end region of a third leg, which can cooperate with the closing latch and / or the unlocking element. Furthermore, the second leg and the third leg can extend substantially opposite to each other. The adjusting mechanism in the counter box can tilt the rocker lever around the tilt axis when the panic function is performed, so that the at least one actuating element can be moved in the direction of the closing latch. By the embodiment as a substantially T-shaped rocker lever with three legs, a simple and cheap implementation of the actuation device in the counter box is possible.

In another advantageous embodiment of the locking arrangement, a first actuating element can protrude in the direction of the closing latch by a second actuating element. In this case, the first actuating element can act on the unlocking element before the impact of the second actuating element on the closing latch. Furthermore, in order to carry out the anti-panic function, the counter-box actuation device can move the unlocking element in the direction of the lock by means of the first actuating element and raise the lock of the closing latch and by means of the second actuating element transfer the latch from open state to closed state. Preferably, the first drive element is made as a drive bead and the second drive element is made as a support area. Thus it can be advantageously ensured that the locking of the locking latch is lifted before the second actuating device acts over the entire surface on the locking latch and transfers the locking latch from the open state to the closed state. Due to the support on the entire surface of the second actuating element on the front surface of the closing latch, high recoil security can be implemented advantageously. As a result, a particularly cheap and simple mechanism can be advantageously implemented to actuate the unlocking element and the closing latch. In addition, the closing latch at the end facing the actuation lever can have a recess above and / or below, which can advantageously increase the range of rotation of the rocker lever. Furthermore, the unlocking element with the adjusting device can be made so that regardless of the closing state of the closing latch and the distance between the inner part and the outer part or the gap width between the actuating device and the actuation region, the unlocking element is fully embedded in the locking latch in the counter box direction.

In an advantageous embodiment of the double leaf door according to the invention, the lock box with the lock front, the closing latch and the lock can be arranged on the active leaf and the counterbox with a closure may be arranged on the passive sheet. Furthermore, to carry out the anti-panic function, a latch and / or an anti-panic bar of the passive leaf act through an adjustment mechanism on the actuation device and activate the counter-box, which then activates the lock box. Furthermore, to carry out the anti-panic function, a latch and / or an anti-panic bar of the active leaf can act on the lock and the closing latch and directly actuate the lock box.

Embodiment examples of the invention will now be explained in detail with reference to the representations of the drawing.

In it they show:

Figure 5: A schematic representation on an enlarged scale of the closing latch of Figure 3 with a third distance A "fitted between the inner part and an outer part of the unlocking element.

As can be seen in Figures 1 to 5, the illustrated embodiment example of a double-leaf door according to the invention comprises an active leaf 3, a passive leaf 5 and an interlocking arrangement 1. In the exemplary embodiment shown the arrangement The locking device 1 comprises a lock box 10 with a lock front 12 and a locking latch 14 and a lock, which in the illustrated embodiment is made as a locking element 16.1. The lock secures the latch 14 in the depicted open state against a transfer to a closed state. Furthermore, the interlocking arrangement 1 comprises a counter-box 30 with a closing plate 32. In the open state, the closing latch 14 engages at least partially in a recess 34 of the closing plate 32. To carry out an anti-panic function an actuation device 40 in the counter box 30 drives a guided unlocking element 20 in the closing latch 14 which raises the locking of the closing latch 14 in the lock box 10 and transfers the closing latch 14 from the open state to the state closed, in which the closing latch 14 releases the closing plate 32 and the door is unlocked.

According to the invention, the unlocking element 20 has an adjustment device accessible from the lock front 12, which in the open state adjusts a gap width S between the driving device 40 and a driving region 26.2 of the unlocking element 20.

As can also be seen in Figure 1, the lock box 10 with the closing latch 14 and the lock, which are arranged inside a casing not drawn in detail, whose wall facing the counterbox 30 is made as a front of lock 12 is arranged on the active leaf 3. The counter box 30 with a casing not drawn in detail, whose wall facing the lock box 10 is made as the closing plate 32 is arranged on the passive leaf 5. The Lock 32 has at least one recess 34 for engaging locking latch 14 and engaging double-acting latches not shown, which may be arranged above and below locking latch 14. To perform the panic function, a latch not shown in detail and / or an anti-panic bar not shown in detail of the passive leaf 5 act through an adjusting mechanism 36 on the actuation device 40 and actuate the counterbox 30, which then activates the lock box 10. To carry out the panic function, a latch not shown in detail and / or a panic bar not shown in detail of the active leaf 3 act on the lock and the closing latch 14 and actuate the lock box 10 directly. Therefore, the double-leaf door can be unlocked and opened by the panic function in the closed state, both by means of a latch and / or panic bar of the active leaf 3, and by means of a bolt and / or panic bar of the leaf passive 5. As can also be seen in Figure 1, an SM gap is formed between the closing plate 32 and the lock front 12, the measurement of which can vary from door to door due to tolerance.

As can also be seen in Figure 1, the lock is made as a locking element 16.1, which is fixedly attached to a movable lock bar 16 shown transparent and in the open state of the locking latch 14 forms a stop for the locking latch. closing 14. The lock collet 16 is movably mounted on the housing of the lock box 10 and can be moved perpendicularly to the sliding movement of the closing latch 14 to cancel the blocking. In the illustrated embodiment, the sliding movement of the latch bolt 14 runs horizontally and the movement of the lock collet 16 runs vertically upwards. Of course, the expert can also use other suitable embodiments for locking the closing latch 14.

As can also be seen in Figures 1 to 5, the closing latch 14 at its end facing the lock has a bevel not drawn in detail and a projection against which the locking element 16.1 rests. The unlocking element 20 has at its end giving the lock a drive bevel 22.1, which in case of a movement of the unlocking element 20 in the direction of the lock comes out of an opening at a lower end of the inclined surface of the locking latch. Lock 14 and lift the locking element 16.1 onto the inclined surface of the locking latch 14. As a result, the lock collet 16 also moves upward. Furthermore, in the exemplary embodiment shown, the lock bar 16 has a guide element 16.2, which is also firmly attached to the lock bar 16 and, due to the movement upwards, rests on an outline not indicated in detail of the lock latch. 14. During the transfer of the closing latch 14 from the open state to the closed state, the contour of the closing latch 14 leads to the guide element 16.2, so that the lock collet 16 continues to move upwards perpendicularly to the closing latch 14 until it reaches a stop not shown in detail and the closing bolt 14 assumes the closed state. In this way, another movement of the closing latch 14 out of the closed state can be advantageously avoided.

As can be seen further in Figure 1, the actuating device 40 comprises a rocker lever 40A, which is made such that it can rock about a rocker axis 41 between an initial position and an end position. In the illustrated embodiment, the rocker lever 40A is substantially T-shaped and comprises three legs 42, 43, 44. In this case, the rocker shaft 41 is arranged in the region of the free end of a first leg 42. A second leg 43 is coupled to the adjusting mechanism 36 in the region of the free end. Furthermore, at least one actuating element 45, 47 is arranged in the region of the free end of a third leg 44, which cooperates with the closing bolt 14 and / or the unlocking element 20. As can also be seen in Figure 1, the second leg 43 and the third leg 44 extend substantially opposite each other. Due to this arrangement, in performing the panic function the adjusting mechanism 36 acts on the region of the free end of the second leg 43 and tilts the rocker lever 40A around the pivot axis 41, so that the free end of the third leg 44 moves with the at least one actuating element 45, 47 in the direction of the closing latch 14. Therefore, to carry out the anti-panic function, the actuation device 40 of the counter box 30 moves the unlocking element 20 in the direction of the locking element 16.1 by means of the first actuating element 45 and raises the lock of the closing latch 14. By means of the second actuating element 36, the actuating device 40 of the counter box 30 transfers the closing latch 14 from the open state to the closed state. In the illustrated embodiment, a first actuation element 45, which is designed as actuation bead 47, projects in the direction of the closing bolt 14 by a second actuation element 47, which is designed as a support area 48. In In this case, the first actuating element 45 acts on the unlocking element 20 before the impact of the second actuating element 47 on the closing bolt 14 and raises the lock of the closing bolt 14. As can also be seen in Figure 1 , the first actuating element 45 acts on the actuating region 26.2 of the outer part 26 of the unlocking element 20. The outer part 26 is supported by a return spring 26.3 which acts against the first actuating element 45. To increase the tilting range of the rocker lever 40A, the closing latch 14 can have a cut-out at the top and / or below at the end that d a to the rocker lever 40A.

As can also be seen in Figures 1 to 5, the actuation region 26.2 is arranged on an outer part 26 of the unlocking element 20, which is arranged so that it can move axially with respect to an inner part 24 of the actuating element unlocking 20. In the illustrated embodiment, the drive bevel 22.1 is made of a releasing element 22, which is designed as a sheet metal part and is attached to the inner part 24. The unlocking element 20 is mounted axially movable or movable in a corresponding passage opening in the closing latch. As can also be seen in Figures 2 to 5, a distance A, A ', A "between the inner part 24 and the outer part 26 and, therefore, also the gap width S represented in Figure 1 between the Drive 40 and drive region 26.2, can be adjusted by a screw element 28 which is screwed into a first threaded hole 24.1 on the inside 24 and a second threaded hole 26.1 on the outside 26. The screw element 28 is preferably made as a setscrew 24A In the illustrated embodiment, the gap width S between the first drive element 45 designed as drive bead 46 and the drive region 26.2 of the outer part 26 of the unlocking element 20 is indicated. Alternatively, the gap width S can also be indicated between the second drive element 47 designed as bearing area 48 and the drive region. Thus 26.2 of the outer part 26. Therefore, the adjusting device acts between the inner part 24 and the outer part 26 and by a screw movement changes its distance from each other A, A ', A ". In this way the gap width S between the at least one actuating element 45, 47 and the closing latch 14 can be linearly varied.

For the variation of the distance A, A ', A "when the door is open, a corresponding tool, for example a screwdriver, can be inserted into the screw element 28, here in the captive screw 28A, and the position of the outer part 26 with the actuation region 26.2 with respect to the first rocker lever 40 A. Starting from a first distance A shown in Figures 2 and 3, which corresponds to the gap width S represented in Figure 1 between the first element of 45 and the actuation region 26.2 of the unlocking element 20 and resulting in a nominal gap size SM between the closing plate 32 and the lock front 12, the screw element 28 can be unscrewed by turning in the opposite direction of the clockwise, so that the first distance A shown in Figures 2 and 3 between the inner part 24 and the outer part 26 increases and a second greater distance A 'shown in Figure 4 results between the inner part 24 and the part Outside 26. By this adjustment process the common actuation path of the rocker lever 40A with the first and second actuation elements 45, 47 and the closing latch 14 with the unlocking element 20 can advantageously be adapted to a greater than the nominal gap size SM between the closing plate 32 and the closing face 12, in which the closing bolt 14 does not penetrate as deeply into the counterbox 30, so that the represented position of the closing bolt 14 represents a nominal gap size SM between the closing plate 32 and the lock front 12.

Starting from the first distance A represented in Figures 2 and 3, the screw element 28 by clockwise rotation can be screwed, so that the first distance A represented in Figures 2 and 3 between the part Inner 24 and outer part 26 is reduced and a third smaller distance A '' shown in Figure 5 results between inner part 24 and outer part 26. Thus, Figure 5 shows a possible minimum distance between inner part 24 and the outer part 26, in which the inner part 24 is adjusted to the outer part 26. By this second adjustment process the common actuation path of the rocker lever 40A with the first and second actuation elements 45, 47 and the closing latch 14 with the unlocking element 2o can be advantageously adapted to a smaller gap size than the nominal gap size SM between the closing plate 32 and the lock front 12, in which the latch The closing bolt 14 penetrates deeper into the counter box 30. The screwing movement is exerted against the force of the return spring 26.3 that acts between the outer part 26 and the closing bolt 14.

In an alternative embodiment not shown, the unlocking element 20 with the adjusting device can be made such that, regardless of the closing state of the closing latch 14 and the distance A, A ', A "between the inner part 24 and outer part 26 or gap width S between the actuator 40 and actuator region 26.2, the unlocking element 20 is fully embedded in the closing latch 14 in the direction of the counterbox.

The embodiments of the interlocking arrangement according to the invention for a double-leaf door advantageously allow an improved, intuitive and easy to carry out adjustment of an interlocking mechanism to a current chink size.
