Description

The invention relates to an arrangement for an escape or emergency exit, according to claim 1. In an escape or emergency exit door, which can be mechanically opened by operating a latch bolt by means of a panic bar or by means of a pusher, there is a need in certain installation situations, opening a to detect such escape or emergency exit door. For this purpose, a so-called escape or emergency exit door control is provided.

An aforementioned arrangement is known from EP 2 169 155 B1 known. This arrangement comprises an additional trap which can be released by means of an electrical drive arranged on the frame side. With only manual actuation of the panic bar or the pusher, the additional trap remains in its trap position, in which the escape or emergency exit door is secured by means of the additional latch to the frame and is not yet openable. To open the door, the additional latch must also be released by activating a switch located near the escape or emergency exit door to activate the electric drive. The operation of the switch is detected and can be reported, for example, the security center of a department store. In this way, if necessary, an alarm can be triggered.

The escape or emergency exit door control described above is used so that in a (legitimate) escape a refugee person can open the door in any case without decentralized support. In the event of an unauthorized door opening (for example, by a thief, who passes through the stolen property stolen in the store through the open escape or emergency exit door through an accomplice), there is at least the possibility that an alarm is triggered.

From the DE 20 2007 015 666 U1 is a building closure with a multipoint interlock known. The Merhpunktverriegelung has two additional locking elements in the form of a respective latch lock. The latch locks interact with two integrated into the frame electric strikes.

From the DE 20 2012 011 844 U1 is a closing device for a door with a lock independent of additional lock known.

Based on an arrangement with an escape or emergency exit door, by operating a latch bolt by means of a panic bar or by means of a pusher can be opened mechanically, there is a need to be able to retrofit an escape or emergency exit door control in a simple manner.

The present invention has for its object to improve an arrangement of the type mentioned so that an escape or emergency exit door control can be retrofitted in a simple manner.

This object is achieved according to the invention in an arrangement of the type mentioned by the features of claim 1.

According to the invention it is possible to retrofit an arrangement with an escape or emergency exit function in a simple manner and while maintaining the existing main lock box with an escape or emergency exit door control. This is particularly advantageous for already existing escape or emergency exits whose doors have a multiple locking. This makes it possible to arrange the trap by replacing an existing locking point and replacing an additional latch bolt; Thus, at least on the door side no further space, for example by milling the door leaf, created.

The electric drive, which cooperates with the release of the case with this, can be arranged at the height of the case frame side, in particular in a region in which in a subsequently retrofitted arrangement already a latch bolt opening of a frame side arranged strike plate is present.

Preferably, the electric drive comprises a frame-side locking element, which in a the Frame closing condition of the door locks the latch and which is unlocked to release the door by means of the electric drive. This makes it possible to open the door while the trap is in its trap position, not in an inserted into the auxiliary lock box position.

According to the invention, the arrangement comprises an additional latch bolt, which is arranged outside the main lock case and outside the additional lock case and can be opened by means of a drive or pull rod by operating the panic bar or the push button. In this way, a multi-locking function can be provided, wherein the panic bar for unlocking preferably all of the latch bars is used, so both for unlocking the latch bolt of the main lock box and for unlocking additional latch bolts, which are arranged in additional lock cases.

In a further embodiment of the invention it is provided that the case and the at least one additional latch bolt seen in the height direction of the door are arranged on the same side relative to the main lock box. The case is seen in the height direction of the door between the main lock box and the additional latch bolt arranged.

According to the invention, the trap is decoupled from a movement of the pull or drive rod, so that a release at the level of the case takes place exclusively by the electric drive and not by means of the panic bar or by means of the pusher.

Thus, an open escape or emergency exit door can be closed independently of the electric drive is it is preferred that the case is displaceable starting from a case position into the additional lock case, in particular against the action of a spring.

For a simplified design of the electric drive, it is preferred that a displacement path of the case is limited from the additional lock case on the case position.

In this context, it is preferred that a stop element is provided for limiting a displacement path of the case, that is motion-coupled with the case and is supported in the case position on a housing of the additional lock case. This allows a simple limitation of the displacement of the trap.

The invention further relates to a method for retrofitting an arrangement for an escape or emergency exit door, wherein the arrangement comprises in an initial state: an escape or emergency exit door arranged on a frame, a main lock box arranged on the door with at least one actuatable by means of a panic bar or by means of a pusher Fallen bolt and at least one additional latch bolt, which is arranged outside of the main lock box in an additional lock case and by means of a Drive or pull rod can be opened by pressing the panic bar or the pusher. Such an arrangement is known by the Applicant's "Multiple Lock SECURY 21 Series".

To retrofit an escape or emergency exit door control in a simple manner, the invention proposes that in the course of retrofitting the at least one additional latch bolt is replaced by a decoupled from a movement of the drive or pull rod trap and that an electric drive is arranged on the frame, by means of which the trap is releasable.

Advantages and embodiments of the method according to the invention have already been described above with reference to the arrangement according to the invention for an escape or emergency exit. Therefore, reference is made to the above description.

Further features and advantages of the invention are the subject of the following description and the diagrammatic representation of a preferred embodiment.

One in the Fig. 1 shown and generally designated by the reference numeral 10 arrangement for an escape or emergency exit comprises an escape or emergency exit door 12 (hereinafter referred to as "door 12"), which at one building-fixed frame 14 is arranged and with which an opening of the frame 14 is closed or released.

The arrangement 10 comprises a main lock box 16 arranged on the door side with a latch bolt 18 which can be actuated in a manner known per se by means of a panic bar 20 shown in sections with dashed lines. By pressing the panic bar 20, the latch bolt is removed from the in Fig. 1 illustrated case position (or out of a further pulled out locking position) transferred to a retracted into the main lock box 16 position.

As an alternative to a panic bar 20, a pusher known per se and therefore not shown can also be used with a handle by means of which a pusher nut 22 can be rotated in order to retract the latch bolt 18 into the main lock box 16 in a manner known per se.

The main lock box 16 preferably has neither a lock cylinder nor an actuatable by means of the lock cylinder latch. This has the advantage that an escape or emergency exit function of the door 12 can not be hindered.

The arrangement 10 comprises a lock cuff 24 arranged on the door side, which is shown interrupted in the drawing for the sake of clarity, but in fact preferably extends in a vertical direction without interruption along an outwardly facing side of the door 12 and is firmly connected to the door 12. Preferably, the main lock box 16 is connected to the lock cuff 24.

The arrangement 10 comprises for a multiple locking of the door 12, a plurality of additional latch bolts, which are each arranged in additional lock boxes. The additional lock cases are preferably connected to the lock cuff 24.

In detail, for example, four additional lock cases are provided. For example, two additional lock cases 26 and 28 are arranged above the main lock box 16. For example, two additional lock cases 30 and 32 are arranged below the main lock box 16.

The additional lock cases 26 to 32 each have a latch bolt 34, each forming an "additional" latch bolt in the context of the present invention and in relation to the latch bolt 18 of the main lock box.

The latch bolt 18 and the additional latch bolt 34 are in their case position and can thus be pressed by a frame side arranged strike plate 36 in the latch bolts 18 and 34 respectively associated lock boxes 16 and 26 to 32.

The additional latch bars 34 are coupled in a conventional manner by means of a drive or pull rod 38 with the operation of the latch bolt 18 through the panic bar 20; an actuation of the panic bar 20 thus causes not only a retraction of the latch bolt 18 in the main lock box 16, but also a retraction of the additional latch bolt 34 in the respective additional lock boxes 26 to 32nd

The drive or pull rod 38 includes a plurality of sections, each other between two in the height direction adjacent lock cases of lock boxes 16 and 26 to 32 extend. These sections are each coupled with each other in movement. To improve clarity, the sections mentioned are shown interrupted in the drawing, in fact, these sections extend between each two lock boxes but without interruption on the side facing away from the door 12 and are covered by the lock cuff 24 and protected.

The above-described and in Fig. 1 illustrated arrangement 10 can be retrofitted with an escape or emergency exit door control as described below to a in Fig. 2 to obtain shown arrangement 40. As part of the retrofitting one of the additional latch bolt 34 is replaced by a trap 42, either while maintaining the existing additional lock box 30 or using a new additional lock box 44th

The latch 42 may resist the action of a spring 46 (see FIG Fig. 3 and 8th ) in the additional lock case 30, 44 and withdraw from the additional lock box 30, 44 out in a maximum (in Fig. 2 shown) trap position move. The latch 42 is decoupled from the movement of the drive or pull rod 38, so it can not be withdrawn by means of the panic bar 20 for release of the door 12 in the auxiliary lock case 30, 44.

For a release of the door at the level of the case 42, a frame side arranged, electric drive 48 is provided. The drive 48 as such is from the EP 2 169 155 B1 known. Therefore, going beyond the description below for the structure and operation of the electric drive on the related description of the EP 2 169 155 B1 Referenced.

The drive 48 comprises a locking element 50, for example in the form of a pawl. The locking member 50 locks in a closed state of the door 12, the latch 42 with the frame 14. To release the latch 42, the locking member 50 is transferred by a motor 52 in a release position, so that the door 12, while the case 42 in its trap position is, can be opened.

The construction and operation of the additional latch bolts 34 will be described below with reference to FIGS FIGS. 3 to 7 described, with reference to the additional latch bolt 34 which is associated with the additional lock box 30, which is arranged below the main lock box 16 and above the auxiliary lock box 32. The operation of the remaining latch bolt 34 and the main latch box 16 associated latch bolt 18 is identical to the operation of the additional latch bolt 34 of the additional lock box 30.

The latch bolt 34 of the additional lock box 30 is displaceably mounted along a horizontal displacement axis 54. The latch bolt 10 is located in the FIGS. 3 and 4 in its case position, in which the latch bolt 10 projects beyond the lock cuff 24 with its run-on slope 56.

In FIG. 4 It can be seen that the latch bolt 34 is provided with a groove 58 extending in its longitudinal direction and open on one side. In this groove 58 is a locking element 60, which is a pivot bearing 62nd pivotally mounted in the groove 58 and thus in the body of the latch bolt 34. The blocking element 60 is provided with a locking nose 64 and a trigger nose 66.

In the trap position, which in the FIG. 4 is represented, the locking nose 64 engages behind the lock plate 24 and prevents further ejection of the spring-loaded latch bolt 34. This spring force is applied by the spring 46, which is pushed onto a spring guide pin 68 and on the one hand on the inner wall of a housing 70 of the additional lock box 30th on the other hand supported on a Ausschubhebel 72.

The Ausschubhebel 72 is pivotally mounted in a bearing 74. The bearing 74 opposite end of the Ausschubhebels 72 engages the trigger nose 66 opposite end of the locking element 60 and urges this under the force of the spring 46 in the extension direction. Since the blocking element 60 is connected via the pivot bearing 62 with the latch bolt 34, this is also urged in the extension direction.

In FIG. 4 Although it can be seen that the extension lever 72 acts on the blocking element 60, the direction of the force of the extension lever 72 does not pass through the pivot axis of the blocking element 60 formed by the pivot bearing 62, so that the extension lever 72 exerts a pivoting moment counter to the clockwise direction on the blocking element 60 , Because of this pivoting moment the locking lug 64 and the trigger tab 66 are lifted out of the groove 58.

When the door 12 is open so the latch bolt 34 is in the in the FIGS. 3 and 4 illustrated trap position, in which a further extension of the Rear grip the locking lug 64 behind the lock cuff 24 is prevented.

When slamming or pushing the door of the latch bolt 34 via the strike plate 36 ( FIG. 6 ) inserted into the auxiliary lock box 30.

Is the door 12 in its closed position and the latch bolt 34 is aligned with an associated latch bolt opening 75 in the door frame-side strike plate 36 (FIG. FIG. 6 ), the fully inserted latch bolt 34 is pushed out of the additional lock box 30 via the extension lever 72. During this Ausschubbewegung the locking element 60 is simultaneously pivoted against the direction of the clockwise direction about the pivot bearing 62. In this case, the trigger nose 66 comes into contact with the edge of the latch bolt opening 75 of the striking plate 36 facing it, as a result of which the blocking element 60 is pushed against the pivoting moment into the groove 58 so far that the locking nose 64 can slide past the lock collar 24. In this way, a locking of the latch bolt 34 in the case position according to FIG. 4 prevents, so that the latch bolt 34 in the in the FIGS. 5 and 6 can extend shown locking position. In this locking position of the latch bolt 34 is about 10 mm to 15 mm further extended from the auxiliary lock box 30, as in the case position according to the FIGS. 3 and 4 ,

In an alternative, not shown in the drawing embodiment, the Ausschubhebel 72 is located after pivoting of the locking element 60 directly to the latch bolt 34 and extends it into the locking position.

How out FIG. 5 As can be seen, the latch bolt 34 has a latch bolt tail 76 with a projection 78. Furthermore, it is off FIG. 5 It can be seen that a latch bolt locking lever 82 is mounted pivotably about a bearing pin 80 and is spring-loaded counter to the clockwise direction via a blocking lever spring 84, which is preferably designed as a leg spring. The latch bolt 34 is in the fully extended position according to FIGS. 5 and 6 That is, in the locking position, then a latch bolt locking edge 86 of the latch bolt locking lever 82 engages the projection 78. Although it can between the projection 78 and the latch bolt locking edge 86, as in FIG. 5 shown, there is a small distance, however, the latch bolt locking edge 86 engages in the displacement of the projection 78th

If now the latch bolt 34 in the course of a manipulation e.g. inserted by means of a tool or the like in the auxiliary lock box 30, the projection 78 comes to the latch bolt locking edge 86 to the system and a further insertion of the latch bolt 34 in the auxiliary lock box 30 is prevented. The latch bolt 34 is thus locked in its locking position against insertion into the additional lock box 30 / secured.

If a latch bolt reset lever 88, which abuts with one arm 90 at one free end of a section 38b of the drive or pull rod 38 and with another arm 92 against a further projection 94 of the latch bolt tail 76, engages via the drive or pull rod 38 Nose 96 of the free end of the arm 92 to a gate 98 of the Fallenriegelelsperrhebels 37 ( FIG. 5 ) and lifts it from its locking position, in which the latch bolt locking edge 86 the projection 78th engages so far out that the latch bolt locking edge 86 emerges from the displacement of the projection 78.

In addition, the arm 92 bears against the further projection 94 and pulls the latch latch 34 into the auxiliary lock case 30 during pivoting of the latch bolt reset lever 88 (FIG. FIG. 7 ). If the latch bolt 34 has been pulled completely into the auxiliary lock box 30, the door 12 can be opened.

When the door 12 is open and the drive or pull rod 38 is in the rest position, the latch bolt 34 is pushed over the extension lever 72 until the locking nose 64 engages the lock cuff 24, as in FIG FIG. 4 shown, engages behind and prevents further expulsion of the latch bolt 34.

When inserting the latch bolt 34 by pressing the door 12 of the latch latch reset lever 88 is indeed pivoted from this case position in the additional lock box 30, the arm 90 but lifted off the section 38b propellant or pull rod 38 so that it is not moved.

About driver 100, 102 of a slidable in the auxiliary lock box 30 in the height direction of the door 12 driver 104 different sections 38a, 38b of the drive or pull rod 38 are coupled to each other motion. The driver 102 has a transmission portion 106 for transmitting movement of the drive or pull rod 38 to a free end of the arm 90 of the latch latch reset lever 88, so that the latch latch reset lever 88 can be pivoted about a relative to the housing 70 fixed pivot bearing 108 in order a manner described unlocking the Fallenriegelsperrhebels 82 and to cause insertion of the latch bolt 34 into the auxiliary lock box 30.

The structure and operation of the latch 42 and associated auxiliary lock box 30, 44 will be described below with reference to FIGS FIGS. 8 and 9 described.

An exchange of the latch bolt 34 of the lock case 30 by the latch 42 can be done while maintaining the lock case 30 and its conversion or by providing a new lock case 44.

Maintaining the lock case 30 and its housing 70, the lock case 30, starting from the above with reference to the FIGS. 3 to 7 described state in the following with reference to FIGS. 8 and 9 described state by the additional latch bolt 34 and the locking member 60 are removed and replaced by a trap 42. To decouple the drive or pull rod 38 of the case 42, it is sufficient to remove the latch latch reset lever 88. In order not to hinder insertion of the latch 42 from a latch position into a retracted into the auxiliary lock box 30 position, also the latch locking lever 82 and the locking lever spring 84 are removed. The remaining components are thus in particular the housing 70, the driver part 104, the spring 46 and the extension lever 72.

The remaining on the housing 70 driver part 104 makes it possible to separately separate separate sections 38a, 38b of the drive or pull rod 38 with each other, in particular, upon actuation of the drive or pull rod 38 by means of the panic bar 20, bypassing the trap 42 an additional latch bolt 34th of Additional lock box 32, so unlock, to be able to.

The spring 46 and the Ausschubhebel 72 have the function to apply the case 42 relative to the additional lock box 30, 44 in the extension direction with spring force. The insertion of the trap 42, starting from the case position according to FIG. 9 takes place by abutment and sliding of a run-on slope 110 of the latch 42 on the locking element 50 of the electric drive 48.

To prevent the trap 42 starting from the in FIG. 9 Trap position shown by means of the spring 46 and by means of the Ausschubhebels 72 in a further extended from the auxiliary lock case 30, 44 locking position can be moved, an abutment element 112 is provided as an additional element. The stop element 112 is coupled with the latch 42 and supports with a rear portion 114 on the further projection 94 of the case 42 from. The further projection 94 of the latch 42 corresponds to the further projection 94 of the additional latch bolt 34 (cf. FIG. 3 ).

The stop element 112 has at least one section 116, preferably two mutually spaced sections 116, 118, which in the extension direction to the front, with housing-fixed stops 120, 122 cooperate and limit a displacement of the latch 42 along the displacement axis 54.

The additional lock case 30, 44 further comprises a cover 124, which forms a part of the housing 70 in the mounted state.
