Description

The invention relates to a drive bolt lock for a door wing and a power wing door having a Fallenauswerfer, a sliding parallel to a forend spool, a Einzugsschieber, for a drive rod, which displaced upon actuation of the spool first Fallenauswerfer and then the intake gate are driven.

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 lower shoot bolt rod are retracted and at the same time are on the trigger slide, the latch and the latch Moving wing lock pushed back into the lock case, so that the door system can be opened.

The EP 1 947 273 A1 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.

From the EP 2 264 268 A2 is a drive bolt lock known in which a manually over the pusher or motor slidable in the lock housing spool first ejected a latch and a bolt ejector and subsequently, ie delayed, the lower and the upper drive rod are retracted. The control of all components via the spool.

The invention is based on the object, a to the EP 2 264 268 A2 to provide an alternative bolt lock.

This object is achieved with a floating bolt lock of the type mentioned in the present invention, that the spool is coupled via a control slot with a lever with the intake slide.

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 over the. Drive rod or the drive rods remains locked. 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 latch of the moving wing lock are pushed out over the ejector (s) during the first movement, which is required, for example, 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.

Another advantage is that by means of the spool while the fall ejector directly actuated, the intake gate but are driven by a lever. The lever is pivotally mounted and has two lever arms, wherein one lever arm for driving via the spool and the other lever arm for the output is used. The length of the lever arms can be adjusted so that optimum movement sequences are achieved for the intake slide. The drive motors can thereby be made smaller and now find room in the housing of the floating bolt lock.

In a further development of the floating bolt lock according to the invention, the spool is driven exclusively by a motor, in particular displaceable. With a manual operation by means of a pusher or a pusher, the spool remains at rest and is not displaced. As a result, the actuating forces are reduced and it requires no freewheel for the coupled with the spool drive motor.

In a preferred embodiment of the floating bolt lock, the spool has a first Control cam having a first and a second control section for the Fallenauswerfer, wherein over the first control portion of the Fallenauswerfer is ejected, and the first control section has a free cut over which a control of the Fallenauswerfers can lift from the first control section. If the spool is in its rest position, then the fall ejector can still be pushed out manually, which is made possible by the free cut in the spool.

If the aileron lock not only be provided with a trap but also with a bolt, then the spool of the floating bolt lock according to the invention on a second control cam with a first and a second control section for a Biegelauswerfer, being discharged over the first control section of the Bolt ejector, and first control section has a free cut over which the control of the Riegelauswerfers can lift off from the first control section. Thus, it is also possible for the Latch ejector that this can be manually operated without the spool is displaced.

The cutout has a triangular cross-section so that the trap ejector and / or the latch ejector can be manually ejected in any position of the control slide.

A refinement of the floating bolt lock provides for a follower and a nut pivoting lever that can be driven by the follower, with which the trap ejector can be pushed out directly or indirectly. The floating bolt lock can be manually operated in this embodiment not only via an actuation of the spool but also via a pusher or a presser bar. 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.

With preference, the nut pivot lever is coupled to a pivotally mounted pull-in rocker for the pull-in slider for the drive rod. The intake rocker is pivotally mounted and has a with the intake gate and a coupled with the Nussschwenkhebel rocker arm, so that optimal leverage ratios can be adjusted by a suitable choice of arm lengths.

In order to avoid a movement of the driving bolt lock, ie when the spool is moved in the lock housing, to avoid that the follower is rotated, the Nussschwenkhebel is coupled via a freewheel with the follower.

A further development of the floating bolt lock provides that the nut pivoting lever meshes with a rotatably mounted first coupling member which pushes out a bolt ejector. In this case, the first coupling member is coupled to a second coupling member and the second coupling member drives a second Einzugsschieber for a second drive rod.

Preferably, by means of the reversing lever of the second Einzugsschieber, the first and second coupling member, the Nussschwenkhebel, the intake rocker and the first Einzugsschieber actuated. The first intake slide thus has no direct connection to the spool.

Further advantages, features and details of the invention will become apparent from the dependent claims and the in the following description, in which a particularly preferred embodiment is described in detail with reference to the drawing.

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 inactive leaf 12 and the inactive leaf 12 has a floating 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 FIGS. 2 and 3 show 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 control slide 36 which has a one of the one end of a driving opening 38, on which the driver of a drive motor 40 engages over which the spool 36 in the longitudinal direction of the floating bolt lock 22 and parallel to the cuff 34 is displaceable. The spool 36 has a first cam 42 (see FIG. 8 ) With a first control section 44 and a second control section 46 for a Fallenauswerfer 48, which engages with a control pin 50 in the first control cam 42. In addition, the control pin 50 is guided in a transverse groove 52 in the housing base 54 such that the Fallenauswerfer 48 can move only transverse to the cuff 34.

The spool 36 also has a second control cam 56 with a first control section 58 and a second control section 60 for a Bolt ejector 62, which engages with a control pin 64 in the second control cam 56. The control pin 64 is likewise guided in a transverse groove in the housing base 54 in such a manner that the bolt ejector 62 can move exclusively transversely to the cuff 34. Both cams 42 and 56 and in particular the two second control sections 44 and 58 each have a cutout 66, whose function will be explained later.

In the FIGS. 4 and 5 the driver of the drive motor 40 is moved by a first distance 68 and thereby the spool 36 is moved to a first position. The two first control section 44 and 58 have the two control pins 50 and 64 of the Fallenauswerfers 48 and 60 Riegelauswerfers displaced transversely to the cuff 34 and placed the two ejectors 48 and 62 in a position in which this the latch and the latch of the lock 20 from the Eject the floating bolt lock 22. The leaf 14 can now be opened.

In the FIGS. 6 and 7 the driver of the drive motor 40 has finally traveled a second distance 70 and thereby displaced the spool 36 in a second position. The two control pins 50 and 64 of Fallenauswerfers 48 and 60 Riegelauswerfers are now in the two second control sections 46 and 60 which secure the two ejectors 48 and 62 against indentations.

The spool 36 also has a control slot 72, in which a pin 74 of a reversing lever 76 engages. The reversing lever 76 is pivotally mounted and has a first pivot arm 78, from which the pin 74 protrudes. The second pivot arm 80 engages behind with its hook-shaped end a driver pin 82 of a driver 84 which is displaceably mounted in the lock housing. At this driver 84, a pull rod 86 is screwed, which extends to the lower end of the floating bolt lock 22 and to which a Einzugsschieber 88 is fixed for the lower drive rod 26.

The driver 84 has a second driving pin 90, on which the hook-shaped end of a second coupling member 92 engages. The second coupling member 92 is pivotally mounted and forms with an extension a slot guide 94 for a pin 96 of a first rotatably mounted coupling member 98. The pin 96 is a sprocket portion 100 opposite, which meshes with a toothing 102 of a Nussschwenkhebels 104. In the nut pivot lever 104 engage two drivers of a follower 106 and at the free end of the lever arm 108, the end of an arm 110 of a pull-in rocker 112 is coupled, which engages with an actuating finger 114 an intake slide 116.

With unactuated drive motor 40 (FIG. FIGS. 2 and 3 ) is the pin 74 at one end of the control slot 72 at. In the intermediate position of the drive motor 40 according to the FIGS. 4 and 5 the pin 74 is located at the other end of the Control slot 72, so that the lever 76 continues to assume its rest position. This means that although the trap ejector 48 and the latch ejector 62 assume their working position, the drive rods 24 and 26 are still pushed out.

In the actuated end position of the drive motor 40, which in the FIGS. 6 and 7 is shown, the pin 74 is taken by means of the control slot 72 and thereby the lever 76 has been pivoted to the working position. By the second pivot arm 80 of the driving pin 82 has been moved. The driver 84 causes via its second driving pin 90, a pivoting of the second coupling member 92, which in turn causes a rotation of the first coupling member 98 via the engaging in the slot guide 94 pin 96. The coupled via the teeth 102 Nutschwenkhebel 104 is also pivoted and takes the intake rocker 112 with.

In this way, during the second operating portion of the drive motor 40, i. only after the ejection of the Fallenauswerfers 48 and the Riegelauswerfers 62, by pulling the reversing lever 76, the pull rod 86 retracted with Einzugsschieber 88 and 112 of the Einzugsschinge 112 Einzugsschieber and thereby solved the two drive rods 24 and 26 from the crossbar 32 and the bottom.

If the espagnolette lock 22 according to the invention is actuated manually by means of a pusher or a push rod, then a first rotation of the pusher nut 106, in which the nut pivot lever 104 is entrained via the two lateral catches, causes a first rotation of the nut pivot lever 104 about the axis of the pusher nut 106, now serving the nut pivot lever 104 as a drive for the intake rocker, the first and second coupling member 98 and 92. The intake rocker 112 and the lever arm of the Nussschwenkhebels 104 form a Fallenauswerferantrieb and the two coupling members 92 and 98 a Riegelauswerferantrieb. The trap ejector 48 and the latch ejector 62 are ejected. By means of the intake rocker 112 and the second coupling member 92 but also the two intake valves 116 and 88 are retracted. It is advantageous that the driving pin 82 of the driver 84 lifts off the reversing lever 76 and thereby the spool 36 is not actuated and remains in its rest position. A displacement of the Fallenauswerfers 48 and the Riegelauswerfers 62 can still take place, since the two control pins 50 and 64 can lift in the free punch 66 of the two control sections 44 and 58.

Even if now the drive motor 40 is actuated, only the spool 36 is moved so that the two control pins 50 and 64 retract from the cutout 66 in the two first control sections 46 and 60 and the lever 76 with your second pivot arm 80 on the driving pin 82nd invests. A provision and defined rest position receive the components via a return spring 118 which urges the Einzugsschieber 88 in its extended position, which in the FIGS. 2 to 5 is shown.
