Simple hook bolts are easy to lift. This can be prevented by opposing bolt combinations comprising two opposing latches. However, known from the prior art opposing bolt must be installed consuming and require a relatively large amount of space.

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 cuff plate, and arranged in the lock case locking arrangement is known, which has an opposite latch combination with a hook-shaped first latch bolt and a hook-shaped second latch bolt, which arranged mutually pivotable are and are movable through an opening in the faceplate between an enclosed open position and an excluded from the lock case locking position, in which engage the lock bolt in each case in a recess in a closing plate. An actuator transferred at a corresponding operation, the opposing lock bolt from the enclosed open position in the excluded locking position or from the excluded locking position in the enclosed open position. In addition, a bolt lock blocks the pivotal movement of the lock bolt in the excluded locking position and releases the pivotal movement in the enclosed open position.

The invention has for its object to provide a lock for a wing, in particular a sliding leaf, and a corresponding system with such a lock, which allows a compact and easy to install lock.

This object is achieved by the features of the castle for a wing, in particular a sliding wing, according to claim 1 and by the features of the system with at least one movable wing, in particular a sliding wing, according to claim 14.

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

In order to provide a lock for a wing, in particular a sliding leaf, which allows a compact and easy-to-install lock, the lock for a wing includes a sliding movably mounted gate valve, in which the actuator and the deadbolt are combined. The gate valve is displaceable between a release position in an enclosed open position and a locked position in an excluded locking position, wherein the gate valve locks the lock bolt in the locked position. Furthermore, the lock comprises a lock case, which is closed on one side by a cuff plate, and arranged in the lock case latch assembly which has an opposite latch combination with a hook-shaped first latch bolt and a hook-shaped second latch bolt, which are arranged mutually pivotable and through an opening in the faceplate between the enclosed open position and the locking position excluded from the lock case are movable, in which the lock bolts each engage in a recess in a closing plate. The actuator transferred at a corresponding operation, the opposing lock bolt from the enclosed open position in the excluded locking position or from the excluded locking position in the enclosed open position, and the lock bar blocks the pivotal movement of the lock bolt in the excluded locking position and releases the pivotal movement in the enclosed open position.

The blocking of the two hook-shaped lock bolt on the locking slide in the locked position allows a simple and robust blocking of the pivotal movement of the lock bolt in the excluded locking position.

In an advantageous embodiment of the lock, the lock bolt can be arranged mirror-symmetrically to one another and each form a locking nose on a first end region, which engage behind an edge of the recess in the closing plate in the excluded state. Here, the locking lugs of the counter-pivoting lock bolt in the enclosed state can face each other. Preferably, the distance between the pivot axes of the two lock bolt is selected so that only a small gap between the locking lugs of the lock bolt results in the enclosed state.

In a further advantageous embodiment of the lock, the counter-pivoting lock bolt can each have at a second end portion a stable bolt with an axial bore, which are rotatably mounted in the lock case. In addition, the counter-pivotable lock bolts each have between the first end portion and the second end portion a first guide contour, which cooperate with a respective formed on the locking slide second guide contour and form a positive connection. Due to the stable design of the bolt results in a particularly robust and compact component, which in combination with the positive connections between the lock bolts and the gate valve provides great security against burglary and manipulation. As a result, a classification into high security classes is possible in an advantageous manner. Due to the axial bore in the bolt, the mountability of the lock bolt can be improved because they can be pre-positioned in a mounting device.

In a further advantageous embodiment of the lock, the second guide contours of the locking slide may each have a driver, which engage in the respective first guide contour of the associated lock bolt and can cause a forced movement of the associated lock bolt at a transition of the locking slide from the locked position to the release position. As a result, an unwanted entanglement of the lock bolt in the lock plate can be prevented in an advantageous manner and the reliability of the lock can be further improved. In addition, at least one magnet can be arranged on an end face of the locking slide, which can hold the lock bolt in the enclosed open position in the release position of the locking slide. This can be prevented in an advantageous manner that the lock bolt in the enclosed open position protrude over the face plate, so that the reliability of the lock can be further improved.

In a further advantageous embodiment of the lock, the lock bolt can rest in the excluded state at the extended in its locking position locking slide. Furthermore, the locking slide in its locking position protrude from the lock case and engage in the recess in the closing plate. This increases the blocking effect against movements in the passage direction.

In a further advantageous embodiment of the lock, the actuating element may comprise an oblique guide slot and an actuating pin guided in the guide slot, which can be acted upon by an actuating means. Here, the oblique guide slot can be caused by the actuating means movement of the actuating bolt, which is perpendicular to the sliding direction of the locking slide, convert into the sliding movement of the locking slide. Furthermore, in each case an angled stop bay can be formed at the two ends of the guide slot. In this case, the actuating pin is in the release position of the locking slide in a first stop bay and in the blocking position of the locking slide in a second stop bay. As a result, the actuating bolt in the respective stop position prevents further sliding movement of the locking slide. The actuating means acting on the actuating bolt may comprise, for example, a pusher or a profile cylinder or a motor drive.

In a further advantageous embodiment of the lock, the lock bolt can each be designed as castings. This allows a particularly cost-effective production of the lock bolt as mass parts.

In an advantageous embodiment of the system, the lock can for example be arranged on a first wing, and the closing plate can be arranged on a second wing or on a frame.
