Abstract

The invention relates to a lock device for a two-leaf door. The lock on the active leaf side comprises a lock case (1a) having a lock mechanism supported therein having a latch bolt (11). The latch bolt can assume a first retracted position, a second extended position, and a third far extended position. The lock mechanism has a blocking device (13), by means of which the latch bolt can be blocked in the far extended third position of the latch bolt. A triggering element (15) is supported in the latch bolt (11) in such a way that the triggering element (15) can be extended and retracted. The triggering element (15) interacts with the blocking device (13) in such a way that the blocking device (13) is activated in the maximally extended position of the triggering element (15) of the far extended third position of the latch bolt (11) and the blocking device (13) is deactivated in the at least partially retracted position of the triggering element (15). This deactivation of the blocking device (13) occurs due to the insertion of the triggering element (15) by means of a lift-out device, which is supported in the counter lock case on the passive leaf side.

Description

Locking device for a door, window or the like with a latch bolt with release member and blocking device

The invention relates to a lock device for a door, a window or the like. The door or window has one with a fixed

mountable frame and an active wing movably mounted on the frame, hereinafter referred to as "wing." In addition, a passive wing may be supported on the fixedly mountable frame, i.e., the door may also be a double-leaf door.

The invention is based on a prior art in which

Locking devices are already known, which have the following features a), b) and c): Feature a): The lock device has a wing side mountable

Characteristic b): The lock mechanism has a latch bolt, which is mounted in the lock case so that it can be moved in and out in the extension direction in a spring-loaded manner, forming a retracted first position (FIG. preferably 0 mm extension length), an extended second position (eg 13 mm

Extension length) and in a still further extended third position (e.g., 20mm extension length). This third extended position is the door locking position.

Feature c): The latch bolt is self-locking. For this purpose, the latch bolt is acted upon by a spring such that the latch bolt moves from the extended second position (e.g., 13 mm extension length) to the further extended third locking position (e.g., 20 mm extension length).

is extended as soon as a detector device determines that the wing is in the closed position. As long as the wing is opened, an extension limiting device acts on the latch bolt, limiting the extension of the latch bolt to the extended second position (e.g., 13 mm extension length). The Ausfahrbegrenzungseinrichtung is turned off when the

Detector device determines that the wing is in the closed position.

Locking devices which are designed with these features a), b) and c) are known from practice, as already mentioned. It is essential that the

Fallen bolt according to feature b) can occupy several positions, preferably 3 positions, ie at least one retracted position and an extended, the door locking position. Preferably, it is three positions, namely a retracted first position, a normally extended second position and a further extended, the door

locking third position. It is also essential in these known locks that according to feature c) the latch bolt is self-locking, i. when the wing is in the closed position, the latch bolt automatically moves to its far extended third position. In this position, the wing is in the

Closed position and locked by the far extended latch bolt. The far-extended latch bolt is blocked in this position against insertion, i. locked.

Such lock devices with latch bolts are known in practice. In DE 20 201 1 01 1 842 U1 such a lock device is described. In the case of the concrete embodiment described there, the detector device is integrated in the latch bolt, namely as a pivot lever which is mounted on the side facing away from the inlet slope of the latch bolt. When the wing is in the closed position, the two-armed lever strikes against the stationary frame and thus lifts the Ausfahrbegrenzung of the latch bolt, so that the latch bolt moves spring loaded in its far extended third position. Disadvantage of this lock is that a manipulation by

Insertion of the latch bolt in the closed position of the door is possible.

From DE 196 52 601 C1 a lock device for a two-leaf door with a pivotally mounted active wing (active leaf) and a pivotally mounted passive wing (passive leaf) is known. The

Locking device has on the active wing a lock with a conventional latch with trap slope and a conventional latch with a flat face without traps on. That is, the lock has a conventional latch and a conventional latch and no hailstones on. The latch and the bolt can be actuated via a handle and a lock cylinder. At the passive wing a mating box with appropriate receptacles for the latch and the bolt of the active wing is provided. In the locked state of the lock device, the latch and the latch of the active wing engage in the corresponding

Recordings of the passive grand piano. The bar is here by a

Locking device locked against closing in the lock case. In the bolt a trigger member is movably mounted, with which the blocking device can be switched to be effective. The lock device can also be unlocked by operating a handle on the passive side. For this purpose, a lifting device is provided in the mating box of the passive wing. When unlocking the passive wing pushes the release member into the bolt, whereby the blocking device is switched to be effective. In the course of unlocking then pushes the

Lift the latch into the lock box of the active sash. The lock device is then unlocked. The lock device with latch and bolt and associated passive wing counter box with lifting device each case and latch requires a complex structure.

In the figures, concrete embodiments are shown by way of example. The figures show:

Figures 1 -5 a first embodiment;

FIGS. 6 to 10 show a second embodiment;

Figures 1 1 to 18 a third embodiment;

Figures 19 to 24 a fourth embodiment. In all four embodiments, each is a

Locking device for a door. The door points one in a fixed

Frame 100 pivotally mounted active wing 10, which is hereinafter referred to briefly as the wing 10. In the wing 10, a lock 1 is mounted on the wing side. The lock 1 has a lock case 1 a, which is installed concealed in the wing 10, in a formed in the wing 10th

Pocket inserted. In the lock case 1 a is the

Lock mechanism stored. It has a retractable and extendable latch bolt 1 1. For actuation, a nut 17 is provided for connecting a handle, not shown. The handle can be a pusher or a push rod. In addition, a cylinder lock 20 is provided in the lock case 1 a, which is actuated by a key. Between the nut 17 and the latch bolt 1 1, a lock gear is mounted with a lever 18 in the lock case. The cylinder lock 20 is connected to the lever 18 via a lock slide 19. Furthermore, a retractable from the lock case and auxiliary latch 12 is provided. It is located below the latch bolt 1 1 and connected to this via a not-shown gear. The lock device is designed as a panic lock device. For this purpose, the latch bolt 1 1 is designed as a self-latching latch bolt, which can take three positions, namely a in the lock case 1 a

retracted first position, an extended second position and an even extended third position. As far as the extension widths of the latch bolt are concerned, it is provided in the illustrated exemplary embodiments that the latch bolt 1 1 is extended by 13 mm out of the lock case in the extended second position and extended out of the lock case by 20 mm in the further extended third position. In this far extended third position of the latch bolt 1 1 is locked, ie blocked against pushing back. The lock can be canceled by a not shown, frame side, ie on or in a fixed frame in the case of a single-leaf door and on or in a passive wing in the case of a double-leaf door - arranged switching off device. These

Turn-off can as unlocking and retracting

be educated. It is referred to below as a lifting device. This lifting device initially acts in a first phase on the mounted in the latch bolt 1 1 trigger pin 15 acts on the free end of the trigger pin 15 to cancel by retraction of the pins 15, the lock. The trigger pin 15 is therefore also referred to as Entriegelungspin. The lifting device acts in addition, when the pin 15 retracted far enough and thus the latch bolt is unlocked, the latch bolt 1 1 directly, to retract the released after the release of the latch latch 1 1. This functionality is present in all four examples shown in the figures. The lock devices shown are each designed as a so-called panic locks, d. H. for use in escape and emergency exit doors. In the three exemplary embodiments illustrated in FIGS. 1 to 18, it is agreed that the triggering member 15 is connected via a

Gear device 16 is mounted in the latch bolt 1 1, wherein the

Gear device 16 is designed so that when retracting the latch bolt 1 1, the trigger member 15 under relative movement to the latch bolt 1 first

forcibly retracts, wherein the trigger member 15 and the latch bolt 1 1 are moved relative to the lock case 1 a in the retraction direction.

It is essential here that the trigger member 15 has a higher

Moving speed than the latch bolt 1 1, so that the Trigger member 15 is fully retracted into the inlet slope 1 1 a of the latch bolt 1 1 with its free end, as soon as the latch bolt has reached its second extended position, which is shown in Figure 2. The first three embodiments shown in Figures 1 to 15 differ in the structural design, in particular as regards the gear 16, which between the release pin 15 and the

Fallen latch 1 1 acts, and as regards the locking device 13, via which the latch bolt 1 1 in the far extended third position lockable, i. can be blocked, this blocking can be released by retracting the trigger pin 15.

The first embodiment in Figures 1 to 5

In the first embodiment of Figures 1 to 5 is the

Transmission device 16, between the trigger member 15 and the

Fallen latch 1 1 acts as a two-armed lever 16 a formed. This two-armed lever 16a is on the latch bolt 1 1, i. on the

Fallenriegelschwanz, rotatably mounted and cooperates with a on the lock case 1 a fixed lip 16p. It is essential that the two-armed lever 16a is connected at one end to the trigger member 15 (in the illustrated case via a slot connection 1 1 V, see Fig. 2 to 4) and cooperates with its other lever arm with the lip 16p. When the trigger member 15 is released from an extended position in FIG. 1, the two-armed lever 16a in FIG. 1 is thus moved counterclockwise and the locking device not shown in FIGS. 1 to 5 is switched off, so that the latch bolt can be retracted further via the lifting device. This is by the 16p with the lip

cooperating two-armed lever 16a increased Retraction speed of the trigger member 15 relative to the

Retraction speed of the latch bolt 1 1 reaches, so that the free end of the trigger member 15 is fully retracted into the opening in the inlet slope 1 1 a of the latch bolt 1 1.

The second embodiment in Figures 6 to 10

In the second exemplary embodiment of FIGS. 6 to 10, in contrast to the first exemplary embodiment, instead of the lock housing-fixed lip 16p, a slide 16c mounted resiliently on the lock housing is provided. This slider 16c has a guide receptacle into which the free end of the two-armed lever 16a engages. About the slider 16c acting spring the trigger member 15 is acted upon in the extended position shown in Figure 6. The pressure spring acting upon the slide 16c thus assumes the function which, in the first exemplary embodiment, takes place via a leg spring, as shown in the detail illustration in FIG. 2a.

In the embodiment of Figures 6 to 10 is the

Locking device 13 shown for the latch bolt. It has a wedge-shaped locking element 13, which cooperates in its locking position in Figure 6 with a stop edge of the latch bolt 1 1. As can be seen in FIGS. 7 to 8, the displacement of the locking element 13a takes place with the displacement of the slide 16c taking place during retraction of the trigger member 15, so that the stop edge of the latch bolt 1 1 is released, thus locking the latch bolt will be annulled. The guide means of the locking element 13 can be supported as one in the lock case 1 a Slotted guide be formed, in which engages the slidably received in a vertical slot of the slider 16c locking element 13a.

The third embodiment in Figures 1 1 to 18

In the third embodiment shown in Figures 1 1 to 18 acts on the latch bolt 1 1 mounted two-armed lever 16a with a two-armed lever 16b together, on the slider 16c

Position as shown in Figure 1 1. For the embodiment, a special embodiment of the locking device 13 is shown in detail in Figures 13 and 14. As can be seen, it has a pivot bolt 13 a, which is rotatably mounted on a pivot bearing on the latch bolt 1 1. Of the

Swivel latch 13a is actuated by a pressure member which on the

Trigger member 15 is fixed. The free end of the pivot bolt 13a cooperates with a vertical sliding bolt 13b, which in the

Locking position in a slot-shaped latch receptacle 13c, which is fixed to the lock housing 1 a, engages. The engagement position is shown in FIG. Figure 14 shows how the sliding bolt 13b is released from the receiving slot 13c in that the pivot bolt 13a is rotated counterclockwise by the action of the fixed to the trigger member 15 pressure piece. The fourth embodiment in FIGS. 19 to 24

The lock 1 has a lock case 1 a with a lock box cover, a lock case bottom and a lock plate on. The lock has the following essential interacting components: a Fallen bolt 1 1, one in the latch bolt 1 1 movably mounted Entriegelungspin 15, an auxiliary latch 12, a nut lever 18, a non-return 13, a nut 17 and a lock cylinder 20. The latch bolt in the fourth embodiment

The latch bolt 1 1 is linearly movable in the lock case 1 a stored. The latch bolt 1 1 has a latch bolt head and a latch bolt tail. The latch bolt 11 can assume three positions: a retracted first position (FIG. 21), an extended second position (FIG. 22) and a widely extended third position (FIG. 19). In the retracted first position of the latch bolt 1 1 is pulled into the lock case 1 a. In the extended second position and also in the widely extended third position of the latch bolt 1 1 is extended from the lock case 1 a such that the latch bolt 1 1 with its latch bolt head from a him assigned

Opening in the lock forend protrudes. In the illustrated fourth

Embodiment is provided in this regard that the latch bolt 1 1 protrudes in the extended second position by 12 mm from the lock case 1 a and that the latch bolt 1 1 protrudes in the widely extended third position by 20 mm from the lock case 1 a.

The latch bolt 1 1 is replaced by a spring 1 1 f associated with it in the

Following latch bolt spring is called, acted upon in the direction of the widely extended third position. The latch bolt spring 1 f is arranged so that it is supported lock box fixed with its one end and with its other end on the latch bolt 1 1 itself supported. In the illustrated fourth

Embodiment, the latch bolt spring 1 1 f is designed as a leg spring. The latch bolt head is provided with a trailing edge. The case slope is used to interact with the fixed door frame 100 or the

Striker of the passive leaf 1 10, during the closing operation just before the wing 10 by e.g. Manual closing of the wing reaches the closed position. During the closing process, it comes to striking the case slope to the stationary door frame 100 and the strike plate of the passive leaf 1 10. The latch bolt 1 1 is pushed against the action of the latch bolt spring 1 1 f in the lock case 1 a during this stop operation. Once the wing has reached the closed position, the latch bolt moves automatically, i. automatically, in its far extended position.

The latch bolt tail has a contact area 1 1 a, the

Cooperation with the still to be described nut lever 18 is used. In the illustrated fourth embodiment of the contact area 1 1 a is formed as a contact edge.

The Entriegelungspin in the fourth embodiment

The unlocking pin 15 is movably mounted in a receptacle of the latch bolt 1 1. The unlocking pin 15 is used to interact with a mounted on the stationary door frame 100 and the inactive leaf 1 10 lifter. The inclusion of the Entriegelungspins 15 in the latch bolt 1 1 is formed so that the direction of movement of the Entriegelungspins 15 is linear and parallel to the direction of movement of the latch bolt 1 1. The receptacle has an opening in the fall slope. In the far extended position of the latch bolt 1, the maximum extended Entriegelungspin 15 protrudes from the opening in the case slope and thereby projects beyond the front end face of the

Latch bolt. In the retracted first position and in the extended second position of the latch bolt 1 1 of the Entriegelungspin 15 is fully in retracted the latch bolt 1 1. The unlocking pin 15 is not out of the opening in the case slope.

The unlocking pin 15 has at its lock-box-side end a pin 15z, which is arranged perpendicular to the direction of movement of the unlocking pin 15 and the latch bolt 1 1. The pin 15z is used for

Interaction with the nut lever 18 to be described later.

The unlocking pin 15 is replaced by a spring 15 f associated with it

Einfahrrichtung applied. The spring 15f can be seen in FIGS. 23 and 24. The spring 15f is supported at one end on a surface of the latch bolt 1 1 and at its other end on a driver of the

Unlocking pin 15 off. The spring 15f is formed in the illustrated embodiment as a helical compression spring.

The non-return lock in the fourth embodiment

The non-return lock 13 is mounted linearly displaceable in the lock case. When the latch bolt 1 1 is in its widely extended third position, as shown in Fig. 19, an edge of the non-return lock 13 on the latch bolt tail and ensures that the latch bolt 1 1 in its far extended third position is not by force can be inserted from the outside in the lock case 1 a. The

Inference lock 13 acts in this blocking the latch bolt 1 1 position as a blocking device, i. Locking device for the

extended latch bolt 1 1. This blocking or locking in the extended position of the latch bolt 1 1 represents a tamper protection when the lock 1 is in its the door leaf 10 and the active leaf locking position. The non-return lock 13 is only in this far extended third position of the latch bolt 1 1 effective. When the latch bolt 1 1 is in its retracted first position (FIG. 21) or in its extended second position (FIG. 22), the non-return latch 13 does not protrude into the movement range of the latch bolt 1 1 and is thus switched to be non-operative.

The non-return lock 13 is acted upon by a spring 13f assigned to it. The spring 13f urges here the non-return lock 13 in their the latch bolt 1 1 blocking position.

The nut lever in the fourth embodiment

The nut lever 18 is pivotally mounted in the lock case to a lock box fixed axis 18x. The nut lever 18 is not spring-loaded. The nut lever 18 is exclusively by entrainment by the other components of the castle, i. through the latch bolt 1 1, through the

Unlocking pin 15, and / or moved by the locknut 17. The free end of the nut lever 18 serves to cooperate with the

Non-return lock 13. The nut lever 18 further has a portion 18a, which serves to cooperate with the abutment edge 1 1 a of the latch bolt 1 1. Further, the nut lever 18 has a portion 18 z, the to

Cooperation with the pin 15z of the unlocking pin 15 is used.

The self-locking in the fourth embodiment

The lock 1 is designed as a self-locking lock. When the door is open 10, the latch bolt 1 1 are in his

extended second position and the auxiliary latch 12 in its extended position. In this position, the latch bolt 1 1 by a holding member (not shown in the figures), which coupled with a latch bolt Slider (not shown in the figures) blocked, held until the door leaf 10 reaches its closed position. The lock has the auxiliary latch 12 as a detector device for controlling the self-locking mechanism. The auxiliary latch 12 is movably mounted in the lock case and can be moved between an extended position in which the auxiliary latch 12 protrudes from an associated opening in the lock plate and a retracted position in which the auxiliary latch 12 is retracted into the lock case 1 a. The auxiliary latch 12 is urged in the direction of its extended position by a spring 12f assigned to it, which is referred to below as the auxiliary latch spring 12f.

When the lock reaches the closed position, both the latch bolt 1 1 and the auxiliary latch 12 are inserted into the lock case. This can be done by striking the door leaf 10 to the door frame 100 or by manual operation of the handle by a user. When planting the door leaf 10 on the door frame 100 in the closed position, the auxiliary latch remains in its retracted position and the latch bolt 1 1 is replaced by the

Self-locking mechanism transferred from its extended second position in its far extended third position. Of the

Self-locking mechanism ensures that the movement of the

Fallen bolt 1 1 automatically takes place from the second extended position to its third extended position as soon as the door leaf 10 has reached its closed position. The unlocking process in the fourth embodiment

The lock 1 can be unlocked in various ways: on the one hand by operating the Entriegelungspins 15 and then inserting the latch bolt 1 1 by a door frame 100 or on the inactive leaf 1 10 mounted lifter, or on the other hand by manual operation of a handle 17 connected to the handle or by actuating the lock cylinder 20. FIG. 19 shows the closed position. In the closed position of the latch bolt is 1 1 in its widely extended third position and also the unlocking pin 15 is extended to a maximum extent. The auxiliary latch 12 stops at the fold of the closed door; So it is partially retracted according to the folded air. Of the

Fallen bolt 1 1 engages in a lock plate, not shown, which is formed on the associated stationary door frame 100 of the single-leaf door or on a fixed leaf 1 10 in the case of a double-leaf door. Of the

Unlocking pin 15 of the latch bolt 1 1 is maximally extended.

Fig. 20 shows the door still in the closed position. However, the Entriegelungspin 15 is already driven by the not shown in or on the fixed frame or the fixed leaf lifter lifter in the latch bolt 1 1 in it. The unlocking pin 15 has reached this position already

Nut lever 18 pivoted clockwise so far that the free end of the nut lever 18, the non-return lock 13 is no longer in blocking engagement.

In Fig. 21, the latch bolt 1 1 is fully retracted by the lifter. The unlocking pin 15 is still retracted. About the Entriegelungspin 15 of the nut lever 18 is further pivoted in a clockwise direction. The latch bolt 1 1 is in its maximum retracted position, contrary to

Activation of his assigned thigh 1 1 f. The auxiliary latch 12 is by the latch bolt 1 1 in its fully retracted position

taken. The auxiliary latch 12 acting spring 12f is compressed. The position in FIG. 21 is obtained when the door 10 passes through the frame 100 when the door is opened and closed. The fully retracted latch bolt 1 1 with fully retracted auxiliary latch 12 provides the

theoretical case is that when passing de wing 10 from the closed position no game remains. The position in Fig. 21 is alternatively achieved by rotational actuation of the handle connected to the nut 17, in this case, the fully retracted position of the latch bolt 1 1 and the auxiliary latch 12 is practically realized.

Fig. 22 shows the door with the wing 10 open. The latch bolt 1 1 is extended to its middle extended position and the auxiliary latch 12 is in its fully extended position.

What is new in comparison with the prior art is that the latch bolt 1 1 is blocked, ie locked, in its widely extended position shown in FIG. 19 in the closed position of the door. This is not known in conventional latch bolts 1 1 as well as in conventional lock traps. Blocking in the extended position is known only for conventional flat-faced latches without a trailing edge. It is also new that in the latch bolt 1 1 a release pin 15 is mounted. Fallen bolts with unlocking pins are not yet known. Unlocking pins are so far known only for conventional latch. A special feature in the arrangement of the Entriegelungspins 15 in the latch bolt 1 1 is that of Unlocking pin 15 is disposed in the slope. This results in a special situation when retracting the Entriegelungspins 15 by the lifter. A complete retraction of the Entriegelungspin 15 is not possible with a conventional lifter, since conventional lifters are designed for retracting a conventional bolt with a flat face, the conventional Entriegelungspin protruding over the flat end face of the bolt. The unlocking pin 15 in the present case has a spring engagement for complete retraction. The spring is applied by a return spring. The return spring 15f is in the

Sectional view shown in Figures 23 and 24. The spring 15f is supported with its one end on a surface of the latch bolt 1 1 and with its other end on a driver of the Entriegelungspins 15 and acts on the Entriegelungspin 15 in the retraction direction. The spring 15f is formed in the illustrated case as a helical compression spring. These

Spring action by the return spring 15 f ensures a complete retraction of the unlocking pin 15 in the latch bolt head, so that the unlocking pin 15 no longer protrudes from the slope of the latch bolt 1 1. The spring action is effective as soon as the unlocking pin 15 is pushed over the lifter so far that the non-return lock 13 is switched to be effective and the nut lever 18 is free. From this point, the unlocking pin 15 is no longer retracted by the lifter, but by the spring action by means of the spring 15f, to the extent that it no longer protrudes beyond the slope of the latch bolt 1 1. The retraction of the Entriegelungspins 15 takes place after the lifting of the latch bolt as follows: Starting from the position in Fig. 21 of the latch bolt 1 1 is moved by the associated spring 1 1 f in the direction of its half extended position. The nut lever 18 is in Counterclockwise about the driver, the end of 1 1 a of

Fallenriegelschwanzes is formed, turned. In a further extension of the latch bolt 1 1 in the direction of Fig. 20 of the nut lever 18 runs with its free end at the lower edge of the return lock 13 in Fig. 20 to the left and reaches the operating slope of the non-return 13th In this position, then after Ereichen the operating slope the

Inference lock 13 is moved by its associated leg spring 13f in the position shown in FIG. 19. Here, the nut lever 18 is further pivoted in the counterclockwise direction, which the unlocking pin 15 against the release pin 15 associated spring 15f extends to its maximum extended position in Fig. 19.
