Description

The invention relates to a drive bolt lock for a door having a leaf, with a Fallenauswerfer, a parallel to a forend displaceable spool, a spool driven by the spool ejector drive, and a Einzugsschieber for a drive rod.

In a preferred escape door solution for double-leaf doors usually flow wing and poppet closure systems are used. On the inactive side so-called bolt locks are used. In a panic actuation of the poppet lock, the upper and the lower shoot bolt rod are retracted and at the same time the latch and the latch of the swing gate lock are pushed back into the lock box via the trigger slide, so that the door system can be opened.

The EP-A-1 947 273 shows such a drive bolt lock, which simultaneously pushes out the case when operating and pulls in the upper and lower drive rod. With this lock so only the complete inactive leaf can be released. It is not possible that only the active leaf lock is released via the drive bolt lock, whereas the inactive leaf remains locked over the drive rods.

If now a double-leaf door system is to be automated by the use of rotary vane drives, also the locking components must be released electrically or by motor. This is done today by means of an integrated in the floating bolt lock electric door opener for releasing the case of the moving wing lock and a built-in frame door opener for the release of the upper drive bolt rod. On the lower drive bolt bar must be dispensed with, since the lock is not mechanically, so operated by a handle and thus the rods would perform no lifting movement.

This type of construction forces the user to use at least two expensive electrical door openers suitable for fire doors. Furthermore, the missing bottom bolt bar weakens the properties of the door in terms of its original fire protection, smoke protection and burglar resistance properties.

The invention has for its object to provide a floating bolt lock, which is electrically actuated and can be released with the depending on the requirement either only the active leaf or both wings.

This object is achieved with a floating bolt lock according to claim 1. Advantageously, a coupling member is provided, which upon actuation of the Spool valve delayed in time, the retraction slide drives.

The driving bolt lock according to the invention has the significant advantage that due to the time delay of the second movement sequence, i. the unlocking of the drive rod, first the case of the moving wing lock is pushed out of the drive bolt lock, so that the inactive wing still remains locked over the drive rod or the drive rods. Then, in a second step, the unlocking of the drive rods, so that the inactive leaf is completely unlocked. He can now also be opened. This is inventively achieved in that the ejection of the case and the collection of the drive rods are carried out in chronological succession. In addition, the invention can be manually operated by means of a pusher bolt lock but also controlled by a motor.

The sequential powered drive bolt lock thus divides the overall movement sequence when you press the lock in two successive courses of motion. The latch and possibly a bolt of the moving wing lock are ejected during the first movement over the ejector or ejectors, which is e.g. is required for the use of access control systems or the automated opening of the active leaf. Thereafter, by means of the second movement sequence, the retraction of the drive bolt rods, which is required for the additional release of the passive leaf.

In contrast to the above-mentioned conventional constructions, the invention can spare the electric openers and use both the upper and lower drive bolt rods.

In a further development of the floating bolt lock according to the invention, the control slide has an idling movement and an adjoining driver section relative to the coupling member. In this way, the movement described above can be easily divided into two movement sections, with only the ejector are operated at idle, but the drive rods remain at rest.

As already mentioned, a bolt ejector and a bolt ejector drive driven by the control slide are preferably additionally provided. As a result, a locked moving wing lock can be unlocked by the bolt is pushed out of the drive bolt lock.

A development of the floating bolt lock provides a follower and a directly or via a transmission gear driven Nutschwenkhebel, which drives the spool or the Fallenauswerferantrieb. The floating bolt lock can be manually operated in this embodiment not only via an actuation of the spool but also via a pusher. By more or less pressing down the pusher only the case is ejected or it is the entire bolt lock unlocked and the inactive leaf can be swung open.

In a preferred development it is provided that the nut pivot lever is formed by a gear section or at least has a gear section. By means of gear sections, on the one hand, relatively high forces, on the other hand, the forces can also be transmitted without play. There is also the possibility of a force or distance translation.

Characterized in that the gear portion meshes with a toothed portion of the Fallenauswerferantriebs or a transmission gear, the pusher movement can directly drive the Fallenauswerferantrieb or the movement can be translated by means of a transmission, so that even small pusher movements are sufficient to push out the trap.

In order to achieve a blocking of the spool in the rest position of the floating bolt lock and thereby locking the drive rods in their extended position, the spool has an edge recess into which a locking pin of the fall ejector and / or the bolt ejector engages when the Fallenauswerfer and / or the Bar ejector occupies its inserted position.

In a preferred variant of the floating bolt lock is provided that the Fallenauswerferantrieb has a control cam and guided in the control cam guide pin. The control cam is provided in the control slide or in the ejector and the guide pin is arranged on the spool or the ejector.

An embodiment of the floating bolt lock provides that the coupling member has a meshing with the Einzugsschieber gear, which is driven by a rack portion of the spool. In this case, the rack portion of the spool at a distance to the gear, so that it is not actuated. The follower section adjoining the idle is formed by the rack section.

Further advantages, features and details of the invention will become apparent from the subclaims and the following description in which two particularly preferred embodiments are described in detail with reference to the drawing. The features shown in the drawing and mentioned in the description and in the claims may each be essential to the invention individually or in any combination.

In the FIG. 1 is a generally designated 10 door, which has a stationary leaf 12 and a moving wing 14. Both the inactive leaf 12 and the active leaf 14 are pivotally connected by hinges 16 to a frame 18. The active leaf 14 can be locked via a lock 20 with the active leaf 12 and the stationary leaf 12 has a drive bolt lock 22, to which an upper drive rod 24 and a lower drive rod 26 are coupled. The lower drive rod 26 engages with its downwardly facing free end 28 in the ground and the upper drive rod 24 engages with its upwardly facing free end 30 in the crossbar 32 of the frame 18 a. Furthermore, it can be seen that the lock 20 and the drive bolt lock 22 are opposite to each other, so that the latch of the lock 20 engages the drive bolt lock 22. Likewise, the latch of the lock 20 engages the drive bolt lock 22.

The FIG. 2 shows the drive bolt lock 22 without housing cover, wherein the drive bolt lock 22 is screwed to a cuff 34. Inside the floating bolt lock 22 is a spool 36 which has a protruding from the lower end of the housing of the floating bolt lock 22 approach 38. At this approach 38, for example, a drive motor attack over which the spool 36 vertical, that is displaced in the longitudinal direction of the floating bolt lock 22 and parallel to the cuff 34 and in the direction of the arrow 92. At the opposite end, the spool 36 on a driver portion 40 in the form of a rack portion 42. In addition, a Fallenauswerferantrieb 44 can be seen, which is pivotally mounted on a pivot bearing 46 in the drive bolt lock 22. According to the Fallenauswerferantrieb 44 is a Riegelauswerferantrieb 48 is provided, which is also pivotally mounted via a pivot bearing 50.

The two ejector drives 44 and 48 are designed substantially double-arm, wherein on one arm 52, 54 each have a pin is arranged, which engages in a horizontal slot 56, 58 in the spool 36. The other arm 60, 62 is each formed like a backdrop and is located on a roller 64, 66 of a Fallenauswerfers 68 and a Riegelauswerfers 70 on. It is also in FIG. 2 recognizable that the roller 64 on a shoulder 72 and the roller 66 in a recess 74 of the spool 36 are. The spool 36 is blocked in this position of the Fallenauswerfers 68 and the Riegelauswerfers 70 against shifting in the direction of the arrow 92.

In the FIG. 2 It can also be seen that the Fallenauswerferantrieb 44 is provided with a sprocket portion 76 which extends between the two arms 52 and 60. With this sprocket portion 76 meshes a gear portion 78 of a Nussschwenkhebels 80, which is rotatably connected to a follower 82. The pusher 82 takes in the FIG. 2 their basic position, in which a hinted only pusher 84 protrudes horizontally.

In the FIG. 3 is that in the FIG. 2 shown bolt lock 22 shown, in which the pusher 84 is pivoted by about 15 ° down, so that it occupies an intermediate position. In this position, the nut pivot lever 80, in particular its gear portion 78, meshes with the sprocket portion 76 of the Fallenauswerferantriebs 44, the upper arm 60 slides along the roller 64 and thereby displaces the Fallenauswerfer 68 in the direction of the cuff 34. The Fallenauswerfer 68 takes in this position its almost completely shifted position, in which he a latch engaging in the bolt lock 22 has completely ejected from the drive bolt lock 22.

In this position of the Fallenauswerferantriebs 44 but also the first arm 52 is pivoted, wherein a pin 86 has been moved in the slot 56, while the spool 36 vertically upwards, i. in the direction of arrow 92 shifts. Due to this sliding movement of the spool 36, a pin 88 is taken from the slot 58, whereby the bolt ejector 48 is pivoted about the pivot bearing 50 in a clockwise direction. At the second arm 62, the roller 66 rolls off, whereby the latch ejector 70 is displaced in the direction of the cuff 34. An engaging in the floating bolt lock 22 bolt is thereby ejected. In addition, the rack portion 42 approaches a gear 90, but does not move it yet.

The translational movements of the trap ejector 68 and the latch ejector 70 are also effected by moving the boss 38 in the direction of the arrow 92, for example by means of a motorized drive.

In the FIG. 4 the pusher 84 is pivoted about 30 ° from the horizontal in its end position, whereby the Nussschwenkhebel 80 and with this the gear portion 78 is also further pivoted, as in the position according to FIG. 3 , The meshing with the gear portion 78 sprocket portion 76 is also further pivoted, whereby the Fallenauswerferantrieb 44 is further rotated in a clockwise direction, and thereby the Fallenauswerfer 68 is still slightly further pushed out of the housing of the floating bolt lock 22. This is effected by virtue of the fact that the roller 64 is still moved slightly further in the direction of the cuff 34 via the second arm 60. The second arm 60 holds the roller 64 in position. The movement according to FIG. 3 is now complete.

About the pin 86 of the first arm 52 of the spool 36 is further displaced in the direction of the gear 90 and in the direction of the arrow 92, so that now the rack portion 42 meshes with the gear 90. About the gear 90, which is now driven, a Einzugsschieber 94, the rack 96, which is opposite to the toothed rack portion 42 with respect to the gear 90, is retracted into the housing of the floating bolt lock 22. At the intake gate 94, the upper drive rod 24 is fixed so that it is displaced in the direction of the drive bolt lock 22 and released by the crossbar 32.

The displacement of the spool 36 in the direction of the arrow 92 also causes entrainment of the pin 88 via the slot 58, so that the bolt ejector 48 is further rotated in the clockwise direction. The second arm 62, on which the roller 66 rolls, holds the latch ejector 70 in position.

Moreover, in particular, out FIG. 5 recognizable that on the spool 36, a further, lower intake slide 98 has been taken in the direction of arrow 92. For this purpose, the spool 36 has a bending tab 100 which carries a nose 102 of the intake gate 98 when moving the spool 36. This bending tab 100 is located in a recess 101 at its upper end and takes the Einzugsschieber 98 in the second movement section of the in the FIG. 3 illustrated liner in his in the FIG. 4 shown end position with.

The movement of the control slide 36 or the movement of the ejector drives 44 and 48 initiated by the pusher 84 is also brought about by a displacement, in particular a motor displacement, of the projection 38 of the control slide 36 in the direction of the arrow 92.

It should be noted that the gear 90 and the rack drive 42 form a coupling member 104 having an idle, in which a movement of the rack portion 42 causes no movement of the gear 90 (movement of the spool of the in FIG. 2 Position shown in the in the FIG. 3 illustrated intermediate position). In a movement of the spool 36 of the in the FIG. 3 shown intermediate position in the in FIG. 4 shown end position, the gear 90 is driven.

Likewise, the nose 102 and the bending tab 100 is a coupling member 106, wherein also here a movement of the spool 36 of the in the FIG. 2 position shown in the FIG. 3 illustrated intermediate position in which the bending tab 100 is moved only within the recess 101, no displacement of the intake pusher 98 causes. In the movement of the in the FIG. 3 shown intermediate position in the in FIG. 4 illustrated end position of the spool 36, the bending tab 100 takes the nose 102 and thus the intake gate 98 with. In this way, the lower drive rod 26 is moved in the direction of the arrow 92 and pulled out of the ground, since the drive rod 26 is fixed to the intake slide 98.

The FIGS. 6 to 9 show a second embodiment in which the spool 36 via the neck 38 also in the direction of arrow 92 can be driven by a motor. The spool 36 has in its lower portion a cam 108 with an inclined portion 110 and a parallel to the direction of the spool 36 according to arrow 92 aligned portion 112. In this control cam 108, a pin 114 is guided, which protrudes from the latch ejector 70. In the region of the upper end of the spool 36 protrudes from this a pin 116 which engages in a control cam 118 which is provided in the Fallenauswerfer 68. The control cam 118 has an inclined Section 120 and a parallel to the direction of the spool 36 according to arrow 92 aligned portion 122. Both the trap ejector 68 and the latch ejector 70 are guided over horizontally arranged guide elements 124 so that they can be moved only in the direction of the cuff 34.

The nut pivot lever 80 of the pusher 82 carries at its free, pivotable end a gear 128 which meshes with a fixed in the floating bolt lock 22 inner tooth segment 130. In addition, engages in the gear 128, a ring gear 126 which is connected to a pivotable about the axis of the follower 82 control lever 132. This control lever 132 is in the FIG. 7 almost completely obscured by Nutschwenkhebel 80, in the FIG. 8 however, shown fully visible because it has been pivoted to a larger pivoting angle. At the free end of the control lever 132 is a control pin 134 which engages in a horizontal groove 136 of the spool 36. The nut pivot lever 80, the gear 128, the internal gear segment 130, the ring gear 126 and the control lever 132 form a transmission gear 138, with which the rotational movement of the nut 82 is translated to a larger, eg twice or three times the rotational angle for the control lever 132.

If the spool 36 by pressing the trigger 84 in the direction of arrow 92 in the in the FIG. 7 shifted intermediate position causes the pivoting of the nut pivot lever 80 causes a rolling of the gear 128 on the internal tooth segment 130, the gear thereby driving the ring gear 126, which in turn pivots the control lever 132. The guided in the groove 136 control pin 134 of the control lever 132 thereby displaces the spool 36 of the in the FIG. 6 shown lower in the in the FIG. 8 shown upper position. The extension of the latch and latch will be described below.

If the spool 36 instead of the pusher 84 by a motor by means of slider 36 in the direction of arrow 92 in the in the FIG. 7 displaced shown intermediate position, the pin 114 is displaced by the inclined portion 110 in the cam 108, and thereby the Bolt ejector 70 is displaced in the direction of the cuff 34. Accordingly, the pin 116 is displaced in the inclined portion 120 of the control cam 118, whereby the Fallenauswerfer 68 is also displaced in the direction of the cuff 34. About the in the direction of arrow 92 displacing groove 136 in the spool 36 of the control pin 134 is taken, whereby the control lever 132 is pivoted counterclockwise. This pivotal movement is transmitted via the ring gear 126 to the gear 128, which rolls on the inner tooth segment 130 and thereby entrains the Nussschwenkhebel 80, whereby the follower 82 in the in the FIG. 7 shown intermediate position is pivoted. The pusher 84 assumes an intermediate position representing, inclined by 15 ° position. It should be noted that the rack portion 42 just comes to rest on the gear 90, but this is not twisted.

The FIG. 8 shows the spool 36 in the fully, shifted in the direction of arrow 92 position in which the Fallenauswerfer 68 and the Liegelauswerfer 70 are still pushed out because the pin 114 along the vertical portion 112 of the cam 108 and the pin 116 along the vertical Section 122 of the control cam 118 are moved, and thereby no additional displacement is effected.

But now drives the rack portion 42, the gear 90, whereby the rack 96 of the Einzugsschiebers 94 displaced against the direction of the arrow 92 and the Einzugsschieber 94 is retracted. A drive rod 24 fastened to the intake slide 94 is thus also retracted.

At the lower end of the spool 36 is a nose 103 which is overlapped by the nose 102 of the intake pusher 98. The sliding movement of the spool 36 corresponds to that according to the embodiment of FIGS. 2 to 4 , Thus, the Einzugsschieber 98 is only then of his in the FIG. 6 shown lower position in the in the FIG. 8 illustrated upper position taken when the spool 36 from its intermediate position according to FIG. 7 in the upper end position according to FIG. 8 is relocated. With the intake slide 98 and the lower drive rod 26 is included.

However, the spool 36 is also moved when by means of a pusher 84, the pusher 82 from the rest position according to FIG. 6 in the liner according to FIG. 7 and from there to the final position according to FIG. 8 in which the inactive leaf 12 can be opened, is twisted.
