Slim case box for a panic door lock

The present invention relates to a mating box for a latch and latch 5 aulweisendes panic door lock with the features a) to h) of claim 1. Known is such a mating box from DE 10 2004 009 973 A1 of the same Applicant.

In the context of the present invention, a panic door is a two-leaf door from which one wing (fixed wing) usually remains closed and the other wing (active wing) is opened and closed during normal operation. People usually pass the panic door through the leaf. In the active leaf, the lock is installed, comprising a latch and a bolt. Both intervenes when the active leaf is closed in a mating box arranged in the fixed wing. To open the active leaf of iS inside a sash pusher is operated, whereby the latch of the lock is pulled out of the mating box and releases the active leaf. To lock the door, the latch is retracted in addition to the case in the mating box, so that despite pressing the sash pusher the door remains closed. 20 To enable a remote operation of the active leaf, counter boxes are known, which are equipped with an electrically actuated pawl. An example of such a counter-box is DE 199 57 999 A1.

Basically, the electrically unlockable pivot latch is similar to those electric door openers that are used behind the cuff of the door frames of 25 front doors. The non-moving during normal operation 2 • f ··············································································· ··· «· ········· ·

Swing trap encloses the trap of the lock and fixes it. Only by electromagnetic actuation (door buzzer), the pivot latch is pivotable, so that the active leaf or the front door can be pushed open from the outside without pressing the inner leaf pusher. This is of course not possible, if the bolt is extended, so the door is locked.

In an emergency, panic doors allow both doors to be opened in the direction of escape to widen the escape route compared to a single-leaf door. For this purpose, the inactive leaf is equipped with a counter-box whose function 10 is to release panic trap and latch of the lock, so as to allow a two-leaf opening the panic door. The counter box is actuated from the inside via a panic trigger, whose actuation movement is transmitted in panic trap to the nut of the counter box. The nut of the counter box receives the actuating movement and initiates the release 15 of bolt and trap. If the inactive leaf is additionally secured by sliding rods, the counter box retracts them.

A fully mechanical counter box for a panic door lock is known from DE 10 2004 009 973 A1. Its mechanism is set up so that upon actuation of the nut, a locking lever initially displaces the bolt of the lock projecting into the counter-box 20, at the same time retracting the upper and lower slide rods and then displacing the latch with the aid of a latch lever from the counter box. This sequence of operations ensures that the latch is not forced back into the lock until the slide bars have already retracted. If the bolt is still in the lock after retracting the 25 sliding bars or even after releasing the latch, it threatens to jam with the weight of the fugitives pressing against the doors. It must be ensured that the bolt is not loaded by lateral forces.

The fully mechanical counter-box 30 described in DE 10 2004 009 973 A1 is distinguished by its high functional reliability. However, his constructively justified width has a negative effect on his aesthetics. The mechanism inside the box takes up a lot of space as a matter of principle, so 3 Μ ························································································ · · · · ··· ················································································································································· The market today calls for much slimmer counter-boxes, as glass doors with a slim frame are considered to be aesthetically pleasing and valuable. The width of the 5 counter box known from DE 10 2004 009 973 A1 means that it is used almost exclusively in massive fixed wings. In principle, no electrical remote control is provided on the purely mechanical counter-box.

From DE 199 57 999 A1 a mechanically overridden door opener is known, which is basically suitable as a counter-box for a panic door. Instead of a trap that urges the trap back, this counter-box is equipped with a mechanically and / or electrically releasable pivoting catch, so that the active leaf can be pushed on without actuating the active-wing pusher moving the latch. Disadvantage of this counter-box is also its considerable structural width. The object of the present invention is to further develop a mating box for a panic door lock of the type mentioned at the beginning, so that it becomes much slimmer and thus occupies less space.

This object is achieved by the use of an electrically and mechanically unlockable pivot latch instead of a mechanical 20 latch lever. This pivotal latch is to be arranged in the counter-box so that it encloses the reaching into the counter-case of the corresponding panic door lock fixing, as long as the pivot latch is in a locked state. In this locked state, the pivot latch is held unschwenkbar in the counterbox. After electrical or mechanical unlocking 25 is the pawl in a release state in which it is pivotally mounted in the mating box. Thus, the case of the panic door lock displace the pivotal latch when the panic door lock is pushed out of the level of the counter box together with the active leaf. An electrically unlockable pivoting latch according to this preferred embodiment of the invention builds smaller than a latch lever, whereby space is saved. In addition, the electrically lockable allows 4 ······························································································· ··· ······ · · ·

Crank catch a remote control of the panic door, so that their leaf can be opened from the outside without the lock latch.

Conveniently, the locking mechanism of the pivoting latch is constructed by means of a pivotally mounted in the mating box, two-armed change whose shorter arm is acted upon by the pivot latch and the longer arm is blocked in the locked state of a parallel to pivotal latch in the mating box pivotally mounted rocker. The pivot latch is unlocked by an electrically or mechanically induced switching movement moves the rocker from its position blocking the change continues. The switching state of the pivot latch is thus defined by the position of the rocker. The rocker is a very lightweight component that can be switched quickly and without the need for large actuation forces. In order to ensure the required locking safety, the rocker does not block the pivoting latch directly, but by interposing the changeover. The fact that the pivotal latch acts on the shorter arm of the change, the force at the end of the longer arm is much lower, so the rocker can support them. Due to the parallel arrangement of pivot axis of the pivoting latch and pivot axis of the rocker, the change loads the rocker along its arms radially to its pivot axis and thus in a direction in which the rocker is particularly sustainable.

The mechanical actuation of the rocker is preferably carried out via a cam gear, which connects the rocker with the third slide in such a way that the guided past the rocker third slide mechanically causes the switching movement of the rocker. The purpose of the geared connection between the third slide and rocker is the mechanical release of the pivoting latch in panic trap. Since the panic door must work even in case of failure of the electrical system, z. B. then, if the electrical lines are destroyed by fire, it must be ensured that the operation of the nut of the counter box via the panic push button puts the normally electrically controlled pivoting latch in its release state. The third slider is driven to retract the upper slide bar via the traction means and performs a sufficiently powerful movement. If the third pusher is preferably located directly in the pancake position, the pusher may be placed directly in the pancake position of the pusher. *** " · · · · · · · · ··· · · · · · · · ·

Area of the pivot latch is located, can be excellent use its actuating movement for switching the rocker.

Practically this is done by the cam gear, the simplest case consists of a slope on the third slide and a projecting into the range of movement of the third slide 5 pin on the rocker. When moving the slider along the rocker, the slope displaces the pin and thus deflects the rocker. In order to obtain an advantageous right / left usability of the counter box, two bevels are provided on the third slide, one of which forms the left side of the cam mechanism with the pin and the other in the right-hand version of the counter box with the pin interacts.

The electrical release of the pivot latch must ultimately lead to a switching movement of the rocker. This is preferably also done via a cam gear, which, however, connects the pivot latch with the armature of an i5 electromechanical actuator. The armature of the electromechanical actuator preferably performs a linear switching movement, which is arranged parallel to the switching movement of the slider. Due to the parallel arrangement of armature guide and third slide a special homogeneity of electrical and mechanical release is achieved. Especially with 20 right / left usable counter boxes homogeneity is advantageous.

To save space, it makes sense to arrange the electromechanical actuator under the change, so that it is largely hidden in the plane of the counter-box by the change.

A further space reduction is achieved in a preferred embodiment of the invention 25 in that the third slide is connected via a traction means with the swirl piece.

In this context, a traction means is an elongated component which is flexible transversely to its longitudinal extension and which can essentially only transmit tensile forces and hardly compressive forces, bending moments or transverse forces. In the simplest case, the traction means is a wire rope or a chain.

The particular advantage of the traction means is the fact that it is due to its flexibility practically along any path in the box laid who can-5 and occupies little space due to its small cross-section. The use of the traction device is based on the knowledge that between the vortex and the third slide only tensile forces are transmitted and thus a pressure-resistant connection between the vertebral and third slide is unnecessary. The restoring force for the third slide is exerted by a spring acting directly on the slide 10, which is why no restoring forces have to be transmitted via the traction means. In addition, the traction device increases the locking safety of the counter box: It is not possible to bypass the panic door mechanism "from behind" by free cutting and pushing down the upper slide bar and thus to actuate the panic trigger virtually from the outside. In addition, the flexurally soft traction means replaces the function of the rotary thrust joint, which connects the third slide with the vertebral piece in the cited prior art. As a result, the reliability of the counter box is further increased.

Preferably, the traction means is guided along the nut, since this allows a particularly compact construction of the counter box. In addition, can be saved by the functional use of the nut as a guide separate guide elements.

The present invention will now be explained in more detail with reference to an embodiment. FIG. 1 a: mating box in locked position, closed, top view; FIG.

FIGS. 1a and 1b show a mating box 1 according to the invention with i5 closed housing 2, in FIG. 1c the housing cover 2a has been removed in order to release the view into the interior of the mating box 1. The mating box 1 is mounted by means of a Stulpbleches 3 in the inactive leaf of a panic door, not shown here. The actuating movement of a panic pushbutton, not shown, is received by the square of a nut 4 20. Slide rods, not shown, are attached at the bottom to a second slide 5, or at the top to a third slide 6. The case of the not shown, corresponding Panic door lock is enclosed by a pivoting latch 7, the bolt of the panic door lock engages in a closed panic door by a well recognizable in Figure 1c latch opening 8 25 through the chair panel 3 in the housing 2 of the counter box 1 a.

The mechanical power flow through the mating box 1 will be described with reference to FIG. In addition, the disclosure of DE 10 2004 009 973 A1 8 •······················································································· ········ ··· additionally used, as far as the present counter-box does not deviate constructively from the known counter-box.

The nut 4 is rotatably supported in the housing 2 between the blocking position shown in FIGS. 2 and 3a, b and an actuating position 5 shown in FIGS. 4a, 4b. The actuation takes place in the clockwise direction in the direction of the arrow B. The nut 4 has at the end of a frame on a first pivot 9, in which a coupling 10 is rotatably mounted. With its other end, the coupling 10 is connected via a further pivot 11 with a first slider 12 which is guided linearly movable in the housing 2. In FIG. 2, the first slider is arranged at the bottom, so that it is partially covered by other components. The best view of the first slide 12 is shown in FIG. 3b. When operating the nut 4 in the direction of actuation B, the coupling 10 converts the rotational movement of the nut 4 into a linear movement of the first slider 12 in the direction of the nut 4 (upward). 15, the first slider 12 has a hidden here backdrop 13, in which a pin 14 of a pivotally mounted in the housing 2 locking lever 15 is guided. As soon as the first slider 12 is pulled up by nut 4 and coupling 10, the link 13 urges the pin 14 in the direction of the face plate 3, whereby the locking lever 15 swings to the left. At the long end of the 2o locking lever 15, a bolt slide 16 is rotatably mounted, which displaces the bolt, not shown, of the panic door lock from the mating box. In the lower end of the housing, the second slider 5 is slidably mounted parallel to the first slider 12. Structurally, both slides are 6, 12 directly to each other and are connected by a driver 17 with each other. When the first slider 12 is pulled up, it takes over the driver 17, the second slider 5 so that they move together. The driver 17 has in the opposite direction to a dead path, which ensures that no power transmission from the second slider 5 to the first slider 12 is possible. This has the following facts: Often 3 0 burglars try to cut the sliding bars from the outside and through

Punch up the lower slide bar to operate the counter box "from behind". In this case, attached to the slide bar second slider 5 would actuate the first slide 12, the remaining opening movement 9. 9

. But the dead path ensures that a power transmission only from the first 12 to the second slide 5 is possible and not vice versa. Thus, thanks to the dead path, a compromise of the counter box by pressing the lower slide bar is excluded, while the 5 permissible actuation direction remains untouched. If one wanted to dispense with this safety aspect, first 12 and second slide 5 could also be combined into one component. The success sought by the invention would nevertheless be achieved.

The second slider 5 is connected at its nut-side end via a rotary push-joint 18 io with a pivotally mounted in the housing 2 swirl piece 19. The rotary sliding joint 18 converts the linear movement of the second slider 5 in a pivoting movement of the swirl piece 19. This movement task could also be fulfilled by a paddock, which would, however, occupy more space. At the other end of the vertebral piece 19 a traction means 20 is attached in the form of a wire rope. The attachment of the traction means 20 in the vertebral piece 19 is achieved via a cable bolt 21 which is pivotally mounted in the vertebral piece 19. Although the traction means is essentially sluggish and therefore can not transmit torque, a angularly movable mounting of the cable bolt 21 in the vertebral piece 19 is useful because so that the traction means 20 is not wound at its anchor point in the vertebral piece 19. A winding would be accompanied by a shortening of the traction device 20, whereby the forces could rise uncontrollably 25 and the traction means 20 could break.

The swirl piece 19 reverses the direction of movement of the second slider 5 and pulls the traction means 20 downwards. This tensile force is introduced along the wire rope immediately past the nut 4 and a deflection roller 22 in the third slide 6, which is pulled in this way down. 30 On the third slide 6, the upper sliding rod of the inactive leaf, not shown, is mounted, which is simultaneously drawn with the lower slide rod, ··. ······················· :::::::::::::::::::::::::::::::::::::::::::::::::: ·. .. 10 will. Furthermore, located on the third slide 6, a slope 23, which is part of a cam mechanism. The cam gear transmits the actuating movement of the third slider 6 on a rocker 24, which defines the switching state of the arranged next to the third slide 6 pivoting catch 7 5. The slope 23 is arranged so that the rocker 24 is actuated only when the slide rods are fully retracted. This ensures that the latch is released only after bolts and slide rods. The second part of the cam gear forms a later described pin 28 on the rocker 24. io The third slider 6 has still a second slope 23 'mirror image of the first slope 23, which is not needed in the drawn left version of the counter box 1. If the counter box, as described below, is used in its not shown right-hand version, instead of the slope 23, the slope 23 'is used. The pivoting catch 7 is mounted pivotably in the housing 2 along an axis of rotation running parallel to the cuffing plate 3. The pivoting is activated or deactivated depending on the Schaitzustand the pivot latch 7: In the locked state, the pivot latch 7 is immobile, in the release state, it is movable. The switching states of the pivotal latch are basically 20 independent of the operating positions of the nut 4. Thus, the pivotal latch 7 by electrical actuation their release state, even when the nut 4 is in its locked position. Conversely, the actuation position of the coupled with the nut 4 third slide 7 forces the release state of the pivot latch 7. The electrical 25 actuation of the pivot latch in the release position exerts, however, no effect on the switching positions of the connected to the nut 4 members. The bolt and the slide bars can therefore not be electrically retracted, which means that in normal operation only the active leaf is opened, unless the panic door is completed. In detail: The pivoting catch 7 acts on the shorter arm of a two-armed change 25, which is pivotally mounted along a direction perpendicular to the housing plane and perpendicular to the pivot axis of the pivoting latch 7. The 11 ·· ·· ·· ··· ··

Swivel sector of the change 25 is limited by two stops 26. As long as the rocker 24 defines the blocking state, the change 25 abuts with the end of its long arm against a contact surface 27 on the rocker 24, which is best seen in Figure 6b. The change 25 is therefore immovable. The force that exerts the pivot latch 7 on the shorter arm of the change 25 is taken over the contact surface 27 of the rocker 24 and discharged into the housing 2. Due to the unequal Hebelarmverhältnis the change 25, the force on the contact surface 27 is significantly less than that with which the pivot latch 7 acts on the shorter arm of the io changer 25. The force on the pivot latch 7 has its origin in the projecting into the Schwenkfaile 7, not shown case. This forces from the inside against the surrounding pivotal latch when the active leaf is pressed in the opening direction. The power transmission between the pivoting catch 7 and the shorter arm of the change 25 takes place via two i5 cam surfaces on the pivoting catch and change. The cam surface 25a associated with the change 25 can be seen in FIG. 5b.

In the operating position shown in Figures 4a, b, the nut 4 is rotated by about 30 ° clockwise. The locking lever 15 is extended in the direction of the Stulpbleches 3, so that the bolt slide 16 has pushed the latch from the 20 bolt opening 8 back. Both connected to the slide rods slide 5, 6 are retracted. The third slider 6 has moved past with its bevel 23 on the rocker 24, so that it has moved the rocker 24 via a projecting from the rocker 24 in the range of movement of the third slide 6 pin 28 from its change 25 blocking position out. 25 The force exerted by the case on the pivot latch 7 on the change 25 force is no longer supported by the contact surface 27, so that the change 25 pivots under the load of the pivot latch with its longer arm in the direction of the Stulpbleches 3. At the same time, the shorter arm of the change of the swing latch 7 differs, so that the unencumbered case of the panic lock 3o can leave the mating box without actuation of the active leaf pusher by pivoting the pivot latch. The pivoting away of the pivot latch is exaggerated in Figures 4a, b. By pressing the panic push-button, even the locked panic door can be pushed open from the inside. 12 ·· 12 ·· ····

Figures 6a and 6b show the switching state defining rocker 24 in detail. This is pivotally mounted in a wall block 29 along an axis which extends parallel to the axis of the pivot latch 7. Figures 6a and b show the rocker 24 in its position defining the release position. In this switch position, the contact surface 27 does not block the change 25, the longer arm of the change dips under the rocker 24 past into the wall block 29. In the locking state defining the switching position, the rocker 24 is approximately in 0 ° position, the contact surface 27 blocks the change 25. io On its underside, the rocker 24 has a cam surface 30, which is part of a cam gear, which the linear actuation movement of Anchor of an electromagnetic actuator, not shown on the rocker 24 transmits. The electromagnetic actuator is located in the plane behind the change 25 and is therefore not visible in the drawings. The fact that the change obscures the electromagnetic actuator, resulting in a small width of the housing 2. The electromagnetically actuated armature of the actuator is guided parallel to the third slide 6 and has a cone on the end, the lateral surface with the cam surface 30 of the rocker 24th interacts. In this way, the cone of the armature 20 transmits its linear switching movement to the rocker 24, which is thereby pushed into its release 25 the releasing position up.

The slides 5, 6 and the pivot latch 7 are spring-loaded, so that the mating box always strives without external switching influence in its blocking division or its blocking state. 25 The control electronics of the electromechanical actuator is housed in a separate electronic module 31, which is arranged on the wall block 29 in the drawings. For this purpose, the wall block 29 has a groove 32 into which a corresponding projection on the housing of the electronic module 31 can be inserted. A similar groove 32 'is also provided opposite the wall block 29 30 in the vicinity of the stops 26 of the change 25. Thanks to these two grooves 32, 32 ', the counter box can be used right / left: The drawings show the counter box 1 in a design for a DIN left 13 ·· ··· ··

Lock. The assembly of the pivot latch 7, change 25, actuator and wall block 29 can also be used vice versa (ie rotated by 180 ° about an axis oriented perpendicular to the cuff plate 3), so that the electromechanical actuator is in the plane above the change 25. 5 The electronics module 31 is then mounted in the other groove 32 ', which is now at 12 o'clock. The electronic module 31 is therefore located in the same place as before, so that its leads do not have to be passed through the interior of the counter box 1. A short line between the electronics module and the electromechanical locking member along the long arm of the change 25 io does not bother. If now the faceplate 3 is replaced, the mating box with the inverted pivoting latch is already converted for the lock of a DIN-right door. The cam gear, which transmits the actuating force from the third slide 6 on the rocker 24, now consists of the pin 26 and the second slope 23 ', which is arranged in the region of the nut 4 on the third slide 6 i5 mirror image of the first slope 23.

Thanks to the separate electronic module 31, the two grooves 32, 32 'and the two bevels 23, 23' on the third slide 6 of the mating box 1 apart from its cuff plate 3 right / left-usable, which significantly reduces the storage. 20 • • • 9 • • • • • • • • 9 9 • • • • • 9 9 • ···· ··· • · • • • 9 • • • • • 99 ·· • · ··· - Claims -
