Description

The invention relates to a lock for at least one leaf, in particular a sliding leaf, of the type mentioned in the preamble of claim 1 and a corresponding system with at least one movable leaf, in particular a sliding leaf, which has such a lock.

Various variations of locks for leaves, in particular sliding leaves, are known from the prior art. The secure locking of sliding doors on a main closing edge is difficult because movements in the sliding direction, lifting movements and movements in the passage direction should be reliably prevented at the same time. Simple hook bolts can be easily lifted out. This can be prevented by bolt combinations that include two bolts running in opposite directions. In addition, the lock should be held securely in its end position to ensure secure locking and unlocking.

From the EP 1 832 698 A1 For example, a lock for a wing, with a lock case, which is closed on one side by a faceplate, and a locking arrangement arranged in the lock case is known, which has a counter-rotating bolt combination with a hook-shaped first bolt and a hook-shaped second bolt, which are mutually pivotable are and are movable through an opening in the faceplate between an enclosed open position and a locked position excluded from the lock case, in which the lock bolts each engage in a recess in a locking plate. When actuated accordingly, an actuating element transfers the opposing ones Lock bolt from the enclosed open position into the excluded locking position or from the excluded locking position into the enclosed open position. In addition, a bolt lock blocks the pivoting movement of the bolt in the locked locking position and enables the pivoting movement in the locked open position.

The pamphlet DE 10 2013 212 514 A1 discloses a door system with at least one movable door leaf, in which a locking device is provided for locking the door leaf in its closed position. The locking device has at least one thrust member which cooperates with at least one locking element, the locking element in its locking position engaging in a stationary or in a locking receptacle arranged on an adjacent door leaf. The locking device has at least one locking factor with at least one electric drive motor for actuating the push element. The push member interacts with at least one locking element which is designed to allow a first direction of movement of the push member and to block a second direction of movement of the push member.

The invention is based on the object of specifying a lock for at least one leaf, in particular a sliding leaf, and a corresponding system with such a bolt combination, which securely holds a sliding leaf in its end position.

This object is achieved by the features of the lock for at least one leaf, in particular a sliding leaf, according to claim 1 and by the features of the system with at least one movable leaf, in particular a sliding leaf, according to claim 17.

Advantageous configurations and developments of the invention are specified in the remaining claims.

In order to specify a lock for a leaf, in particular a sliding leaf, which is securely held in its end positions, an actuating device comprises a push element coupled to at least one lock bolt, which is mounted displaceably between an initial position and an end position, and a latching mechanism which is in a first position releases the thrust element for a thrust movement towards the end position and in a second position blocks the thrust element in a predetermined latching position, the latching mechanism in the second position releasing the thrust element for a thrust movement towards the end position and for a counter thrust movement in Blocked towards the starting position, the locking mechanism in a third position releasing the thrust element for a counter-thrust movement towards the starting position. Furthermore, the lock includes a lock case, which is attached to one side is closed by a faceplate, and a locking arrangement arranged in the lock case, which has the at least one lock bolt, the at least one lock bolt being movable through an opening in the faceplate between an enclosed open position and a locked position excluded from the lock case, in which the at least one lock bolt engages in a corresponding recess of a locking plate. With a corresponding actuation, the actuating device transfers at least one lock bolt from the enclosed open position into the excluded locking position or from the excluded locking position into the enclosed open position.

In addition, a system is proposed which has at least one wing and such a lock. The system can be designed, for example, as a door system with at least one door leaf or as a window system with at least one window leaf.

The latching mechanism holds the pushing element in a predetermined latching position after a first pushing movement during a subsequent counter-pushing movement, the locking mechanism releasing the pushing element for a subsequent second counter-pushing movement after a subsequent second pushing movement. As a result, the lock can be held securely in its end position and secure locking and unlocking of the lock can be ensured. In addition, the thrust element cannot move from its end position to the starting position by itself due to a shock or impact. In this way, it can be ensured on an escape sliding door that the lock does not move from its enclosed open position to the locked locked position by itself.

In an advantageous embodiment of the lock, the locking arrangement can have a counter-rotating bolt combination which can have a hook-shaped first lock bolt and a hook-shaped second lock bolt, which can be arranged pivotably against one another. Such a counter-rotating bolt combination makes it possible to prevent the two lock bolts from being easily lifted out in an advantageous manner.

According to the invention, the locking mechanism comprises a locking element and a spring element acting on the locking element, which presses the locking element in the second position against a locking lug arranged on the pushing element so that the pushing element is fixed in the locking position. In order to enable a simple adjustment of the locking element, the locking element can be mounted in the lock case such that it can rotate about an axis of rotation. The locking element can each have a recess on two opposite sides. In addition, the latching lug can be arranged in one of the recesses in the second position and blocked against movement in the counter-thrust direction. The locking element can, for example, be designed as a rectangular locking plate. This enables a particularly simple and inexpensive design of the locking element.

In a further advantageous embodiment of the lock, the spring element can be designed as a leg spring, wherein a free end of a first leg can rest against a bearing point, and the first leg can be connected to a second leg via a deflection guided around a deflection element, the free end of which as Arch can be formed. In addition, the arch of the spring element can rest on the locking element and transmit a spring force of the spring element to the locking element.

According to the invention, the locking lug transfers the locking mechanism from the first position to the second position during a first pushing movement of the pushing element in the direction of the starting position following a first pushing movement in the direction of the end position second position in the third position, and wherein the locking lug transfers the locking mechanism from the third position to the first position during a second counter-pushing movement of the pushing element in the direction of the starting position following a second pushing movement in the direction of the end position.

In a further advantageous embodiment of the lock, the end position of the pusher element can correspond to the enclosed open position of the two lock bolts, and the starting position of the pusher element can correspond to the locked position of the two lock bolts, whereby the two lock bolts can be in the enclosed open position when the pusher element is in the locking position.

In a further advantageous embodiment of the lock, the push element can be designed as a push rod with a toothed segment and at least one coupling element. As a result, the push rod can easily be coupled to a drive via the toothed segment and / or simply to a lock cylinder via a first coupling element and / or simply to a handle follower via a second coupling element.

In a further advantageous embodiment of the lock, the lock bolts can be arranged mirror-symmetrically to each other and each form a locking nose at a first end area, which in the locked state engage behind an edge of the recess in the lock plate and can face each other in the locked state. The distance between the pivot axes of the two lock bolts is preferably selected such that, in the locked state, there is only a small gap between the locking lugs of the lock bolts.

In a further advantageous embodiment of the lock, the actuating device can comprise an actuating element which can be coupled to the pushing element via an actuating bolt. The actuating element can be designed, for example, as a sliding element with a bolt lock, which between a release position in the enclosed open position and a blocking position in the excluded locked position can be moved. In this case, the actuating element can, with a corresponding actuation, transfer the opposing lock bolts from the enclosed open position into the excluded locking position or from the excluded locking position into the enclosed open position. In addition, the bolt lock can block the pivoting movement of the lock bolt in the locked locking position and release it in the locked open position. Furthermore, the actuating element can comprise an inclined guide slot in which the actuating bolt can be guided. The inclined guide slot can easily convert a movement of the actuating bolt caused by the pushing element, which runs perpendicular to the sliding direction of the actuating element, into the sliding movement of the actuating element. In addition, an angled stop bay can be formed at each end of the guide slot. The actuating bolt can be arranged in the excluded locking position in a first stop bay and in the enclosed open position in a second stop bay.

In an advantageous embodiment of the system, the lock can be arranged on a first wing, for example, and the locking plate can be arranged on a second wing or on a frame. In addition, for example, a handle or a profile cylinder or a motor drive can act on the sliding element to operate the lock.

The arch 34.4 of the spring element 34 rests on the locking element 32 and transmits a spring force of the spring element 34 to the locking element 32.

How out Fig. 1 , 3 , 5 and 8th As can be seen, the push element 6 is designed as a push rod 6A with a toothed segment 6.1 and at least one coupling element 9. In addition, in the illustrated embodiment, the push element 6 is coupled via a transmission device 5 designed as a gear 8 to a further push element 7 designed as a push rod 7A with toothed segment 7.1. In the illustrated embodiment, the thrust element 6 is coupled to a first additional lock, not designated in any more detail, which is designed, for example, as a locking rod protruding downward from the lock case 3. The further push element 7 is coupled to a second additional lock, not designated in any more detail, which is designed, for example, as a locking rod protruding upward from the lock case 3. In addition, the transmission device designed as a gear 8 converts a thrust movement of the thrust element 6 into an opposite counter-thrust movement of the further thrust element 7 or converts a rotary movement of the gear wheel 8 via the toothed segments 6.1, 7.1 into corresponding translational movements of the thrust elements 6, 7. The rotation of the gear 8 can be generated, for example, by a drive motor, not shown. In the illustrated embodiment, the thrust element 6 is coupled to a lock cylinder, not shown in detail, via a first coupling element 9 and can be coupled to a handle follower via a second coupling element, not shown in detail. As a result, the sliding element 6 for actuating the lock 1 can be acted upon by a handle and / or profile cylinder and / or motor drive.

How out Fig. 1 , 3 , 5 and 8th As can also be seen, the bolt straps 12A, 12B are arranged mirror-symmetrically to one another and each form a locking lug 14A, 14B at a first end area, which in the locked state engages behind an edge of the recess in the closing plate 5, as shown in FIG Fig. 1 can be seen. How out Fig. 5 and 8th As can also be seen, the locking lugs 14A, 14B of the lock bolts 12A, 12B, which can be pivoted in opposite directions, face one another in the locked state and are arranged inside the lock case 3. In the illustrated embodiment, the two lock bolts 12A, 12B are arranged mirror-symmetrically to a central axis of the opening in the face plate 3.1, the distance between the pivot axes of the two lock bolts 12A, 12B being selected so that there is only a small gap between the locking lugs when locked 14A, 14B of the two lock bolts 12A, 12B, as shown in FIG Fig. 5 and 8th can be seen.

How out Fig. 1 , 3 , 5 and 8th As can also be seen, the actuating device 20 comprises an actuating element 20A which is coupled to the pushing element 6 via an actuating bolt 24. In the illustrated embodiment, the actuating element 20A is designed as a sliding element with a bolt lock 20B, which can be displaced between a release position in the enclosed open position and a blocking position in the excluded locked position. When actuated accordingly, the actuating element 20A transfers the oppositely rotating lock bolts 12A, 12B from the enclosed open position into the excluded locking position or from the excluded locking position into the enclosed open position. How out Fig. 1 As can also be seen, the bolt lock 20B blocks the pivoting movement of the lock bolts 12A, 12B in the locked locking position. How out Fig. 5 and 8th It can also be seen that the bolt lock 20B releases the pivoting movement in the enclosed open position. In addition, the actuating element 20A comprises an inclined guide slot 22 in which the actuating bolt 24 is guided, so that the inclined guide slot 22 a movement of the actuating bolt 24 caused by the thrust element 6, which is perpendicular to the The sliding direction of the actuating element 20A extends, converts into the sliding movement of the actuating element 20A.

How out Fig. 1 , 3 , 5 and 8th As can also be seen, an angled stop bay 26A, 26B is formed at each end of the guide slot 22. Here, the actuating pin 24 is arranged in the locked locking position in a first stop bay 26A, as shown in FIG Fig. 1 can be seen, and in the enclosed open position arranged in a second stop bay 26B, as shown in FIG Fig. 5 and 8th can be seen.

How out Fig. 1 , 3 , 5 and 8th As can also be seen, the lock bolts 12A, 12B, which can pivot in opposite directions, each have a stable bolt 16A, 16B with an axial bore at a second end area, which are rotatably mounted in the lock case 3. The oppositely pivotable lock bolts 12A, 12B each have a first guide contour between the first end area and the second end area, which each interact with a second guide contour formed on the bolt lock 20B and form a form fit. How out Fig. 1 It can also be seen that, in the locked state, the lock bolts 12A, 12B lie against the bolt lock 20B that has been extended into its locking position. Here, the first lock bolt 12A, arranged at the top in the illustration, rests with the first side on a first contact surface of the bolt lock 20B arranged at the top in the illustration and engages behind with its locking nose 14A an edge of the recess in the strike plate 5 arranged at the top in the illustration first lock bolt 12A with a second side arranged opposite to the first side on an edge of the opening in the faceplate 3.1 arranged at the top in the illustration. The second lock bolt 12B, which is arranged at the bottom in the illustration, lies with the first side on a second contact surface of the bolt lock 20B arranged at the bottom in the illustration and engages behind with its locking nose 14B an edge of the recess in the strike plate 5, which is arranged below in the illustration. At the same time, the second is located Lock bolt 12B with one opposite to the first Side arranged second side to an edge of the opening in the faceplate 3.1, which is arranged below in the illustration.

How out Fig. 1 As can also be seen, the illustrated lower starting position of the push element 6 corresponds to the locked position of the two lock bolts 12A, 12B. How out Fig. 5 As can also be seen, the illustrated upper end position of the push element 6 corresponds to the enclosed open position of the two lock bolts 12A, 12B.

How out Figs. 1 and 2 As can also be seen, the locking lug 38 arranged on the push element 6 is arranged below the locking element 32 in the starting position of the push element 6. The arc 34.4 of the second spring leg 34.3 rests in the illustrated first position of the latching mechanism 30 in a first recess 32.1 of the locking element 32.

How out Figures 3 and 4 As can also be seen, the locking lug 38 acts during a first pushing movement Auf1 directed upwards in the illustration on the locking element 32, which rotates slightly counterclockwise against the spring force of the spring element 34, but the arc 34.4 of the second spring leg 34.3 does not move out of the first recess 32.1 moved out. The first pushing movement Auf1 of the pushing element 6 is transmitted by the actuating bolt 24 to the actuating element 20A, which transfers the two lock bolts 12A, 12B from the locked locking position towards the locked open position.

How out Figures 5 and 6 As can also be seen, the thrust element 6 is displaced to its end position in which the latching lug 38 is arranged above the locking element 32. By the spring force of the spring element 34, the locking element 32 is rotated back again in a clockwise direction and the latching mechanism 30 again assumes the first position, as shown in FIG Fig 7 can be seen.

How out Figures 8 and 9 As can also be seen, the locking lug 38 acts on the locking element 32, which rotates counterclockwise against the spring force of the spring element 34, with the arc 34.4 of the second spring leg 34.3 moving out of the first recess 32.1 during a first counter-thrust movement Ab1 directed downwards in the illustration moved out and rests against a straight side of the locking element 32. In addition, a second recess 32.2 of the locking element 32 clamps the locking lug 38 so that the thrust element 6 is fixed in the predetermined locking position and blocked for further movement in the direction of the starting position.

How out Fig. 8 As can also be seen, the actuating bolt 24 is still arranged in the second stop bay 26B in the latching position of the thrust element 6 and the two lock bolts 12A, 12B are still in the enclosed open position. Thus, the locking mechanism 30 prevents the pushing element from moving into the starting position by an unwanted first counter-pushing movement Ab1, which is triggered for example by vibrations or a blow, and the two lock bolts 12A, 12B from being moved into the locked locking position.

In order to lock the lock 1 again, the locking element 32 is removed from the in FIG. 3 by a second pushing movement Auf2 directed upwards in the illustration Fig. 9 shown locking position moved towards the end position. As a result, the locking lug 38 acts against the spring force of the spring element 34 on the locking element 32 and rotates the locking element in the counterclockwise direction. When the locking lug 38 has left the second recess 32.2, the spring force of the spring element 34 turns the locking element 32 into an in Fig. 10 third position shown, in which the locking element 32 is arranged horizontally.

How out Fig. 11 As can also be seen, in the case of a second counter-thrust movement Ab2 directed downward in the illustration, the locking lug 38 acts on the locking element 32, which counterclockwise counteracts the spring force of the spring element 34 rotates until the bow 34.4 of the second spring leg 34.3 rests in the second recess 32.2 and the locking element 32 is again in its first position. In contrast to the Fig. 2 however, the locking element 32 has rotated 180 ° and the arc 34.4 rests in the second recess 32.2 and not in the first recess 32.1. The second counter-thrust movement Ab2 of the thrust element 6 is transmitted by the actuating bolt 24 to the actuating element 20A, which transfers the two lock bolts 12A, 12B from the enclosed open position in the direction of the excluded locking position.

Embodiments of the lock according to the invention can be used in a door system or a window system with at least one movable leaf, in particular a sliding leaf. Here, the lock 1 can be arranged on a first wing and the locking plate 5 on a second wing or on a frame. The actuating means acting on the thrust element 6 can comprise a pusher or a profile cylinder or a motor drive. Here, the actuating means can be coupled to the pushing element 6 via coupling means, such as for example thrust plates, vortex levers, rocker arms or the like, and can move it.

Embodiments of the lock according to the invention comprise a latching mechanism which advantageously prevents the lock from being unintentionally locked.
