Description

The invention relates to a drive bolt lock for a door having an active leaf, with a latch ejector, a control slide that can be displaced parallel to a faceplate, a latch ejector drive driven by the control slide, and a retraction slide for a drive rod.

In a preferred escape door solution for double-leaf doors, active leaf and inactive leaf locking systems are usually used. So-called espagnolette locks are used on the passive leaf side. When the passive leaf lock is actuated in a panic, the upper and lower driving bar rods are retracted and at the same time the latch and the bolt of the active leaf lock are pushed back into the lock case via the release slide so that the door system can be opened.

the EP-A-1 947 273 shows such a shoot bolt lock which, when actuated, simultaneously pushes out the latch and pulls in the upper and lower drive rods. With this lock, only the complete passive leaf can be released. It is not possible that only the active leaf is released via the espagnolette lock, whereas the passive leaf remains locked via the espagnolette.

If a double-leaf door system is now to be automated using swing leaf drives, the locking components must also be released electrically or by motor. Today this is done by means of an electric door opener integrated in the shoot bolt lock to release the latch of the active leaf lock and a door opener built into the frame to release the upper shoot bolt rod. The lower drive bar rod has to be dispensed with, since the lock is not operated mechanically, i.e. via a handle, and the rods would therefore not perform any lifting movement.

This type of construction forces the user to use at least two expensive electric door openers suitable for fire doors. Furthermore, the lack of a lower driving bolt rod weakens the properties of the door with regard to its original properties in terms of fire protection, smoke protection and burglar resistance.

The invention is based on the object of providing a shoot bolt lock which can be actuated electrically and with which either only the active leaf or both leaves can be released, depending on the requirements.

This object is achieved with a shoot bolt lock according to claim 1. A coupling element is advantageously provided which, when the control slide is actuated, drives the draw-in slide with a time delay.

In the case of the shooting bolt lock according to the invention, due to the time delay of the second sequence of movements, i.e. the unlocking of the connecting rod, the latch of the active leaf lock is first pushed out of the shooting bolt lock so that the inactive leaf remains locked via the connecting rod or the connecting rods. The drive rods are then unlocked in a second work step so that the inactive leaf is completely unlocked. It can now also be opened. According to the invention, this is achieved in that the extension of the latch and the retraction of the drive rods take place one after the other. In addition, the espagnolette lock according to the invention can not only be operated manually by means of a handle but can also be controlled by a motor.

The sequential motor-driven shoot bolt lock thus divides the overall sequence of movements when the lock is actuated into two sequences of movements running one behind the other. The latch and, if necessary, a bolt of the active leaf lock are pushed out via the ejector (s) during the first movement, which is necessary e.g. for the use of access control systems or the automated opening of the active leaf. Then, by means of the second sequence of movements, the espagnolette rods are drawn in, which is necessary for the additional release of the inactive leaf.

In contrast to the above-mentioned conventional constructions, the electric opener can be saved with the invention and both the upper and lower drive bar rods can be used.

In a further development of the espagnolette lock according to the invention, the control slide has an idle position opposite the coupling member and an adjoining driver section. In this way, the sequence of movements described above can be easily divided into two movement sections, with only the ejectors being actuated when idling, but the drive rods remaining at rest.

As already mentioned, a bolt ejector and a bolt ejector drive driven by the control slide are preferably also provided. This means that a locked active leaf lock can also be unlocked by sliding the bolt out of the espagnolette lock.

A further development of the shooting bolt lock provides a handle follower and a follower pivot lever which is driven directly or via a transmission gear and which drives the control slide or the latch ejector drive. In this embodiment, the espagnolette lock can be operated manually not only by actuating the control slide but also by means of a lever handle. By depressing the handle more or less far, only the latch is pushed out or the entire espagnolette lock is unlocked and the inactive leaf can be swiveled open.

In a preferred development it is provided that the nut pivot lever is from a gear section is formed or has at least one gear portion. By means of gearwheel 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 path transmission.

Because the gear section meshes with a toothed section of the latch ejector drive or a transmission gear, the trigger movement can directly drive the latch ejector drive or the movement can be translated by means of a gear so that even small trigger movements are sufficient to extend the latch.

In order to block the control slide in the rest position of the shoot bolt lock and thereby lock the drive rods in their extended position, the control slide has an edge recess into which a locking bolt of the latch ejector and / or the bolt ejector engages when the latch ejector and / or the The bolt ejector assumes its pushed-in position.

In a preferred variant of the shooting bolt lock it is provided that the latch ejector drive has a control cam and a guide pin guided in the control cam. The control cam is provided in the control slide or in the ejector drive and the guide pin is arranged on the control slide or on the ejector drive.

An exemplary embodiment of the espagnolette lock provides that the coupling member has a gearwheel which meshes with the draw-in slide and which is driven by a toothed rack section of the control slide. In this case, the toothed rack section of the control slide is at a distance from the gearwheel when idling, so that it is not actuated. The driver section adjoining the idle is formed by the rack section.

Further advantages, features and details of the invention emerge from the subclaims and the following description, in which two particularly preferred exemplary 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 can each be essential to the invention individually or in any combination.

In the Figure 1 a door designated as a whole with 10 is shown, which has an inactive leaf 12 and an active leaf 14. Both the inactive leaf 12 and the active leaf 14 are pivotably connected to a frame 18 via hinges 16. The active leaf 14 can be locked to the active leaf 12 via a lock 20 and the inactive leaf 12 has a espagnolette 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 crossbeam 32 of the frame 18. It can also be seen that the lock 20 and the espagnolette lock 22 are opposite one another, so that the latch of the lock 20 engages in the espagnolette lock 22. The bolt of the lock 20 also engages in the shoot bolt lock 22.

the Figure 2 shows the espagnolette lock 22 without the housing cover, the espagnolette lock 22 being screwed to a cuff 34. In the interior of the espagnolette lock 22 there is a control slide 36 which has a shoulder 38 protruding from the lower end of the housing of the espagnolette lock 22. A drive motor, for example, via which the control slide 36 is displaced vertically, that is to say in the longitudinal direction of the espagnolette lock 22 or parallel to the cuff 34 and in the direction of the arrow 92, can act on this projection 38. On the opposite At the end, the control slide 36 has a driver section 40 in the form of a rack section 42. A latch ejector drive 44 can also be seen, which is pivotably mounted in the shoot bolt lock 22 via a pivot bearing 46. In accordance with the latch ejector drive 44, a bolt ejector drive 48 is provided, which is also pivotably mounted via a pivot bearing 50.

The two ejector drives 44 and 48 are essentially double-armed, with a pin being arranged on each arm 52, 54, which engages in a horizontal elongated hole 56, 58 in the control slide 36. The other arm 60, 62 is each configured like a link and rests on a roller 64, 66 of a latch ejector 68 or a bolt ejector 70. In addition, in Figure 2 It can be seen that the roller 64 is located on a shoulder 72 and the roller 66 is located in a recess 74 of the control slide 36. In this position of the latch ejector 68 or of the bolt ejector 70, the control slide 36 is blocked against displacement in the direction of the arrow 92.

In the Figure 2 it can also be seen that the latch ejector drive 44 is provided with a toothed ring section 76 which extends between the two arms 52 and 60. A gearwheel portion 78 of a nut pivot lever 80, which is rotatably connected to a follower 82, meshes with this gear rim portion 76. The handle follower 82 takes in the Figure 2 their basic position, in which a pusher 84, only hinted at, protrudes horizontally.

In the Figure 3 is that in the Figure 2 The shooting bolt lock 22 shown is shown in which the handle 84 is pivoted downwards by about 15 ° so that it assumes an intermediate position. In this position, the nut pivot lever 80, in particular its gear section 78, meshes with the ring gear section 76 of the latch ejector drive 44, the upper arm 60 sliding along the roller 64 and thereby displacing the latch ejector 68 in the direction of the cuff 34. In this position, the latch ejector 68 assumes its almost completely displaced position in which it has completely pushed a latch engaging in the espagnolette lock 22 out of the espagnolette lock 22.

In this position of the latch ejector drive 44, however, its first arm 52 is also pivoted, with a pin 86 being displaced in the elongated hole 56 and thereby displacing the control slide 36 vertically upwards, i.e. in the direction of arrow 92. Because of this sliding movement of the control slide 36, a pin 88 is taken along by the elongated hole 58, whereby the bolt ejector drive 48 is pivoted about the pivot bearing 50 in the clockwise direction. The roller 66 rolls off the second arm 62, as a result of which the bolt ejector 70 is displaced in the direction of the cuff 34. A bolt engaging in the espagnolette lock 22 is pushed out as a result. In addition, the rack section 42 approaches a gear 90, but does not yet move it.

The displacement movements of the latch ejector 68 and the bolt ejector 70 are also caused by the fact that the extension 38 is moved in the direction of the arrow 92, for example by means of a motor drive.

In the Figure 4 the pusher 84 is pivoted by approx. 30 ° from the horizontal into its end position, whereby the nut pivot lever 80 and with it the gear wheel section 78 is also pivoted further than in the position according to FIG Figure 3 . The toothed ring section 76 meshing with the gear section 78 is also pivoted further, as a result of which the latch ejector drive 44 is rotated further clockwise and the latch ejector 68 is thereby pushed slightly further out of the housing of the shoot bolt lock 22. This is achieved in that the roller 64 is 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 Figure 3 is now fully completed.

Via the pin 86 of the first arm 52, the control slide 36 is displaced further in the direction of the gear 90 or in the direction of the arrow 92, so that the rack section 42 now meshes with the gear 90. Via the gear 90, which is now driven, a retraction slide 94, the rack 96 of which, with respect to the gear 90, is opposite the rack section 42, is drawn into the housing of the espagnolette lock 22. The upper drive rod 24 is fastened to the draw-in slide 94, so that it is displaced in the direction of the drive bolt lock 22 and released by the transverse bar 32.

Moving the control slide 36 in the direction of the arrow 92 also causes the pin 88 to be entrained via the elongated hole 58, so that the bolt ejector drive 48 is also rotated further in the clockwise direction. The second arm 62, on which the roller 66 rolls, holds the bolt ejector 70 in position.

It is also, in particular, off Figure 5 It can be seen that a further, lower draw-in slide 98 has been taken along in the direction of arrow 92 via the control slide 36. For this purpose, the control slide 36 has a flexible tab 100 which, when the control slide 36 is moved, takes a nose 102 of the retraction slide 98 with it. This bending tab 100 rests in a recess 101 at its upper end and takes the draw-in slide 98 in the second movement section from the one in FIG Figure 3 liner shown in its in the Figure 4 end position shown with.

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

It should also be pointed out that the gear wheel 90 and the rack drive 42 form a coupling member 104 which has an idle mode in which a movement of the rack section 42 does not cause any movement of the gear wheel 90 (movement of the control slide from the position shown in FIG Figure 2 position shown in the Figure 3 shown intermediate position). When the control slide 36 is moved from that in the Figure 3 intermediate position shown in the Figure 4 However, the gear 90 is driven.

Likewise, the nose 102 and the bending tab 100 represent a coupling member 106, with a movement of the control slide 36 from the one shown in FIG Figure 2 position shown in the Figure 3 The intermediate position shown, in which the bending tab 100 is only moved within the recess 101, does not cause any displacement of the draw-in slide 98. When moving from the in the Figure 3 intermediate position shown in the Figure 4 The illustrated end position of the control slide 36 takes the bending tab 100 with it, the nose 102 and thus the draw-in slide 98. In this way, the lower drive rod 26 is moved in the direction of arrow 92 and pulled out of the ground, since the drive rod 26 is fastened to the draw-in slide 98.

the Figures 6 to 9 show a second exemplary embodiment in which the control slide 36 can also be driven by a motor via the extension 38 in the direction of the arrow 92. In its lower region, the control slide 36 has a control cam 108 with an inclined section 110 and a section 112 oriented parallel to the direction of displacement of the control slide 36 according to arrow 92. A pin 114, which protrudes from the bolt ejector 70, is guided in this control cam 108. In the area of the upper end of the control slide 36, a pin 116 protrudes therefrom, which engages in a control cam 118 which is provided in the latch ejector 68. The control cam 118 also has an inclined section 120 and a section 122 oriented parallel to the direction of displacement of the control slide 36 according to arrow 92. Both the latch ejector 68 and the bolt ejector 70 are guided via horizontally arranged guide elements 124 in such a way that they can only be moved in the direction of the faceplate 34.

The pivoting lever 80 of the follower 82 carries on its free, pivotable end a gear 128 which meshes with an internal tooth segment 130 fixed in place in the espagnolette lock 22. In addition, a toothed ring 126 engages in the toothed wheel 128 and is connected to a control lever 132 which can be pivoted about the axis of the handle follower 82. This control lever 132 is in the Figure 7 almost completely covered by the nut pivot lever 80, in the Figure 8 however, shown fully visible, since it has been pivoted through a larger pivot angle. At the free end of the control lever 132 there is a control pin 134 which engages in a horizontal groove 136 of the control slide 36. The nut pivot lever 80, the gear wheel 128, the internal tooth segment 130, the ring gear 126 and the control lever 132 form a transmission gear 138 with which the rotary movement of the nut 82 is translated to a larger, for example twice or three times the angle of rotation for the control lever 132.

If the control slide 36 by actuating the trigger 84 in the direction of the arrow 92 in the Figure 7 If the intermediate position shown is shifted, the pivoting of the nut pivot lever 80 causes the gear wheel 128 to roll on the internal tooth segment 130, the gear wheel thereby driving the ring gear 126, which in turn pivots the control lever 132. The control pin 134 of the control lever 132 guided in the groove 136 thereby displaces the control slide 36 from the one in the Figure 6 shown lower in the in the Figure 8 shown upper position. The extension of the latch and the bolt is described below.

If the control slide 36 is instead of the trigger 84 by a motor by means of slide 36 in the direction of arrow 92 in the Figure 7 If the intermediate position shown is displaced, the pin 114 is displaced by the inclined section 110 in the control cam 108, and as a result the bolt ejector 70 is displaced in the direction of the faceplate 34. Correspondingly, the pin 116 is displaced in the inclined section 120 of the control cam 118, as a result of which the latch ejector 68 is also displaced in the direction of the faceplate 34. The control pin 134 is carried along via the groove 136 in the control slide 36 which is displaced in the direction of the arrow 92, as a result of which the control lever 132 is pivoted counterclockwise. This pivoting movement is transmitted via the ring gear 126 to the gear wheel 128, which rolls on the inner tooth segment 130 and thereby takes the nut pivot lever 80 with it, whereby the handle follower 82 is in the position shown in FIG Figure 7 is pivoted intermediate position shown. The pusher 84 assumes the position which is an intermediate position and is inclined by 15 °. It should also be noted that the toothed rack section 42 is just coming into contact with the toothed wheel 90, but has not yet rotated it.

the Figure 8 shows the control slide 36 in the completely shifted position in the direction of arrow 92, in which the latch ejector 68 and the bolt ejector 70 are still pushed out, since the pin 114 along the vertical section 112 of the control cam 108 and the pin 116 along the vertical Section 122 of the control cam 118 are displaced, and thereby no additional displacement is effected.

Now, however, the rack section 42 drives the gear 90, as a result of which the rack 96 of the draw-in slide 94 is displaced against the direction of the arrow 92 and the draw-in slide 94 is drawn in. A drive rod 24 attached to the draw-in slide 94 is thus also drawn in.

At the lower end of the control slide 36 there is a nose 103 which is overlapped by the nose 102 of the draw-in slide 98. The displacement movement of the control slide 36 corresponds to that according to the exemplary embodiment of FIG Figures 2 to 4 . Thus, the draw-in slide 98 is only then removed from its in the Figure 6 shown lower position in the Figure 8 shown upper position when the control slide 36 from its intermediate position according to Figure 7 in the upper end position according to Figure 8 is relocated. With the pull-in slide 98, the lower drive rod 26 is also included.

The control slide 36 is also displaced when, by means of a pusher 84, the pusher follower 82 is moved from the rest position according to FIG Figure 6 in the intermediate layer according to Figure 7 and from there to the end position according to Figure 8 , in which the inactive leaf 12 can be opened, is rotated.
