Description

The invention relates to a latch closure, comprising a first closure housing having a handle, a buckle and a lock, and a second closure housing having a recess for receiving the closure in the closed state.

Trap locks are used, for example, in windows, doors or flaps to keep them in the closed position. A closure housing of the trap closure is arranged on a stationary frame or the like, the other closure housing is arranged on a movable, usually swing-frame or a door or window sash. The closure housing, in which the clasp is received in the locked state, has a rear grip, whereby the clasp is held in the closed state. An opening of the movable frame, the window or door leaf is possible in this state only after the withdrawal of the buckle against a spring force. The lock in the closed state by means of a "nose member" which locks the lock in the locked state.

In some cases, however, it is desirable that in the locked state, an "emergency release" is possible, for example, to allow opening of the trap closure from the back.

The invention is therefore based on the object of specifying a trap closure, on the one hand enables reliable locking and on the other hand, an emergency opening.

To solve this problem is inventively provided in a trap closure of the type mentioned that the lock has a movable by locking and unlocking the lock stop blocking an opening of the handle in the locked state.

In contrast to known latch closures according to the invention, the handle is blocked instead of the clasp. In this way, a reliable locking is given, since the handle to be opened for opening can not be raised. On the other hand, an emergency opening is possible by the clasp can be pushed back at least with a suitable opening tool against the spring force to open the trap closure.

According to a development of the latch closure according to the invention, the lock can be designed as a cylinder lock. Preferably, the stop is arranged on an inner end portion of the cylinder lock, so that it is rotated when opening or closing the lock about the longitudinal axis of the cylinder.

A particularly reliable function of the trap closure results when the stop blocks a locked portion of the handle concealed by the first closure housing when the lock is locked. The closed state of the lock is not directly visible from the outside.

In order to provide even greater protection against unwanted opening attempts, it may be provided that in the case of the latch closure according to the invention, the first closure housing and / or the second closure housing by means of fastening means, in particular screws and nuts, are fastened to the frame or the like, wherein the fastening means below Covers are arranged, which are not removable in the locked state. These covers can be designed and arranged so that they are accessible only in the open state, that is rotated or pivoted handle so that they can be removed. After the covers have been removed, they release the screw or nut used as fastening means. In the closed state, that is, when the handle is not raised or swung up and the cylinder lock is locked, but the fasteners are not accessible, whereby a secure protection is achieved.

In a further embodiment of the invention, it may be provided that the latch closure has at least one signal means, in particular a lighting means, in particular a light-emitting diode, which indicates a status information. For example, the lighting means may indicate the opening condition, which may be indicated by a lit or non-illuminated light-emitting diode. Likewise, two or more such bulbs may be provided which have the same or different colors, so that a first color can indicate a closed state and a second color an open state of the trap closure. Furthermore, for example, an error can be displayed in this way.

It is also within the scope of the invention that in at least one closure housing a sensor for detecting an open or closed state of the trap closure and / or the clasp is arranged. If appropriate, this sensor can cooperate with the signal means or illuminant mentioned, so that an opened or closed state detected by the sensor is indicated by the signal means. Alternatively or additionally, it can be provided that a sensor signal generated by the sensor is transmitted to a component arranged remotely, for example a control device, so that it can be evaluated by the control device. An optional development of the invention provides that the trap closure comprises a radio module which is designed for the wireless transmission of information, in particular status information, to a receiver. In this variant, no complex and disturbing wiring of one or more sensors is required, instead, the sensor signals are sent wirelessly to a receiver for further processing there.

The in Fig. 1 in a plan view and in Fig. 2 In a sectional side view shown latch closure 1 comprises a handle 2, a clasp 3, which is acted upon by a compression spring 4, which moves the clasp 3 in a rear handle 5 of a closure housing 6. The handle 2 is arranged on a first closure housing 7, which comprises a cylinder lock 8 in addition to the clasp 3. In the Fig. 1 and 2 the trap closure 1 is shut off.

The closure housing 6 is arranged by means of fastening means 9 on a stationary frame, the closure housing 6 is attached by means of fastening means 10 to a pivotable frame.

The cylinder lock 8 comprises a stop 11 which is arranged at right angles to the longitudinal axis of the cylinder lock 8 and is rotatable by 90 ° or 180 ° when opening and closing the cylinder lock 8 by means of a key. In the in Fig. 2 shown position of the trap closure 1 is locked. The stop 11 blocks an inner end portion 12 of the handle 2, so that it can not be raised or pivoted and thus can not be opened.

The fastening means 9, 10, with which the first closure housing 7 and the second closure housing 6 are attached to a frame or the like, are located below covers 13, 14, in the in the Fig. 1 and 2 shown locked position can not be removed. Removing the cover and thus disassembly of components of the trap closure 1 is possible only in the open, unlocked position.

In order nevertheless to allow an opening in an emergency situation, the clasp 3 can be pushed back with a suitable tool against the force of the compression spring until it is no longer in the rear handle 5 of the closure housing 6, then the trap closure 1 can be swung open, even if the cylinder lock 8 blocked with its stop 11, the end portion 12 of the handle. In the case of latch 1, an emergency release is possible because in the locked state, the handle 2 and not the clasp 3 is locked.

The 3 and 4 show the trap closure 1 in a plan view and a sectional side view in the unlocked position. In the unlocked state, the handle 2 is swung up, thereby the clasp 3 has been withdrawn from the handle 2, that is, it is located in Fig. 4 right, so that they no longer blocked the rear handle 5 of the closure housing 6. In this position, the handle 2 can be lifted with the entire closure housing 7, whereby the trap closure 1 is opened. In the in Fig. 4 shown open position is the clasp 3 right, in the Fig. 2 shown locked position, the clasp 3 is left, while the handle 2 is locked.

Fig. 5 shows a perspective view of the trap closure 1 with removed covers. In Fig. 5 the first closure housing 7 and the second closure housing 6 with removed covers 13, 14 are shown. Fig. 6 shows a sectional view along the line VI - VI of Fig. 1 , that is transverse to the fastening means 9, 10. After removing the covers 13, 14, the fastening means 9, 10 through openings of the closure housing 6, 7 accessible, so that assembly or disassembly is possible. In Fig. 5 it can be seen that the cylinder lock 8 is arranged on the closure housing 7. The handle 2 has a recess 15 which is penetrated by the upper end of the cylinder lock 8 in the closed state.

When the trap closure is opened by a movement of the handle 2, projections 16 of the handle 2 engage corresponding recesses 17 of the clasp 3, which is thereby pulled into the closure housing 7, whereby the lock is released. The structure of these components is best in Fig. 7 to recognize that shows the essential components of the trap closure 1 in a perspective view.

In Fig. 5 it can be seen that the closure housing 6 has on its outer side designed as light-emitting diodes 18 bulbs, these are however optional. The LEDs indicate an open or closed or locked state of the latch closure 1. In the closure housing 6, a sensor may be arranged, which detects the opening state of the trap closure 1 and forwards to a control device or the like. For this purpose, the closure housing 6 at one end a closure cap 19 to connect corresponding lines.

In the interior of the closure housing 6 may alternatively or additionally be arranged a radio module (not shown), which is designed for the wireless transmission of information, in particular status information of the trap closure 1, to a receiver. In this way, the trap closure 1 may be part of an automatic production line or the like.

Fig. 8 shows the trap closure 1, consisting of the stationary closure housing 6 and the movable closure housing 7, which are each mounted on a frame section 20, 21. The stationary frame profile 20 is part of a manufacturing cell, which is closed by the frame profile 21, which forms a flap, a window or a door. Access to the manufacturing cell is thus opened or closed by the trap closure 1. An unwanted disassembly of the latch closure 1 in the locked state is not possible because the fastening means 9, 10 are covered by the covers 13, 14. The latch closure 1 can be opened in the locked state, however, by pushing back the clasp from the back or the bottom of the closure housing 7 forth to provide an emergency release available.
