Description

The present invention relates to a channel latch for mounting in a door or window sash, comprising a forend for securing the channel latch to a rabbet of the door or window sash and at least one with a translational movement from a locking position to an unlocking position and back convertible locking element, wherein the Drive of the at least one locking element, an electric motor is provided.

For example, a canister latch is off DE 20 2006 008 969 U1 known. Can-hangers are used in particular for the definition of fixed leaf double-leaf door or window systems. To actuate the locking elements, a lever pivotally mounted in the lock housing of the can latch has to be pivoted out of the plane of the cuff. To do this, you must grasp behind the lever with your finger or with your fingernail and, as a rule, this will be pivoted out of the forend against a preload. For this operation, on the one hand, a certain amount of force is required and, on the other hand, there is a risk of injuring yourself during operation.

Locking elements for door or window sash with the features mentioned are made DE 689 02 285 T2 . EP 0 942 135 A1 . EP 1 158 121 A2 . EP 2 749 721 A1 and EP 2 703 583 A2 known. In these, however, a complex mechanical transmission between the electric motor and the locking elements is always formed. These locking devices are so expensive to install and expensive due to the high number of components.

A canister with the features of the preamble of claim 1 is made EP 1 283 318 A1 known.

It is therefore an object of the present invention to at least partially solve the problems described with reference to the prior art and, in particular, to provide a can-type latch which is easy to operate without injuring itself.

This object is achieved by a canister with the features of the independent claim. Advantageous developments of the can crucible are specified in the dependent claims and in the description, wherein features of the advantageous developments, taking into account the claims in a technologically meaningful manner are combined with each other.

The object is achieved in particular by a channel latch with the features mentioned above, wherein a driven by the electric motor threaded spindle is mounted directly on a shaft of the electric motor and wherein the at least one locking element is so directly coupled to the threaded spindle, that a rotation of the threaded spindle is translated into the translational movement of the locking element, wherein the locking element moved out in the locking position of a lock body and retracted in the unlocked position in the lock body.

The invention provides in its basic idea that the locking element does not have to be manually operated, but that an electric motor is provided, which transfers the at least one locking element from the unlocked position into the locking position and back. The locking and unlocking can be triggered, for example, by pressing a simple switch.

The locking element is in particular that element which is translationally moved by the motor. On the locking element can each desired closure rods, for example in the form of square bolts or round bars, are mounted so that the can latch can be easily adapted to different applications. In particular, the channel latch comprises two locking elements, which are moved out of the lock housing on opposite sides in the locking position and are driven into the lock housing in the unlocked position.

But it can also be provided that exactly one motor is provided in particular with gear for each locking element.

It can further be provided that at least one switch for activating the motor or at least one push-button adapter for the switch is at least partially arranged in the forend. The particular designed as a push button switch can be arranged for example in a counterbore in the forend. The switch for the engine is thus easily accessible. By actuating the switch, the motor is activated and moved the at least one locking element either in the locking position or in the unlocked position. It may be provided a circuit that detects the achievement of a resistance and stops the engine before reaching the locked or unlocked position. This can happen, for example, if the door or window sash is not aligned in a predetermined position by the receptacles for the locking rods. If two switches are provided, then one switch is provided for triggering the locking operation and the other switch for triggering the unlocking operation.

In one embodiment of the channel latch is provided that at least one sensor is provided which detects the reaching of the locking position and / or the unlocked position. Such a sensor can be realized for example by a micro-switch, which is actuated by the locking element directly or indirectly upon reaching its unlocked position or locking position. As sensors but other elements can be used, which can determine the position of the locking element, such as rolling elements, reed contacts, photocells or optocouplers. The one or more sensors may be disposed on separate circuit boards or on a one-piece circuit board. In particular, two or four sensors are provided.

In order to simplify the production of the channel bolt, it can be provided that the forend is fixed to a front wall of a lock body and the lock body is designed so that the electric motor with the threaded spindle and the locking element can be mounted without tools. The forend is fastened in particular by means of blind rivets on the front wall of the lock body. In this way, a standard lock body can be combined with different cuffs so that the forend can be selected for a particular application. The lock body is designed in particular as an injection molded part which integrally forms a side wall and the walls adjacent thereto. The second side wall is formed as a lid, which can be releasably connected to the lock body. On the inside of the lock body, receptacles for the elements of the channel bolt are formed in particular by recesses and projections, so that these elements can first be inserted into the lock body and held there in a predetermined position. By attaching the lid, which may also have on its inside projections and recesses for the elements of the Kantriegels, the elements are then fixed in the lock body. In particular, in the lock body receptacles for the electric motor, the threaded spindle, a threaded spindle bearing bush, the switch and the sensors are provided. The forend can be fixed in the lock body to the front wall of the lock body after mounting the elements of the can-bolt in the lock body.

Alternatively, it can also be provided that the forend and the lock body are integrally formed. In addition, it would be possible that the face plate and the lid are integrally formed.

On a front wall 9 of the lock body 8, a face plate 2 is fixed, with which the channel latch 1 is attached to a fold of a door or window sash. The channel bar 1 comprises two locking elements 3, which in the in Fig. 2 shown unlocking position in the lock body 8 are driven in. In the in Fig. 1 shown locking position, the locking elements 3 are moved out of the lock body 8. In a mounted in a door or window sash locking rods are attached to the locking elements 3 each extending in the locked position on the door or window sash out. To trigger a transfer of the locking elements. 3 from the locking position in the unlocked position or back a switch 6 is arranged in the forend 2.

By pressing the switch 6 are in the 3 and 4 shown electric motors 5 activated, which are each connected to a threaded spindle 4. The threaded spindles 4 are mounted with their electric motors 5 opposite ends in sockets 12. The running as an angle locking elements 3 are each guided with an internal thread on the external threads of the threaded spindle 4, so that caused by the electric motors 5 rotation of the threaded spindles 4 is translated into a translational movement of the locking elements 3.

In addition to the switch 6, two sensors 7 are arranged in the lock body 8, wherein the left sensor 7 detects the locking position and the right sensor 7, the unlocked position. It can also be provided in each case two sensors for detecting the locking position and the unlocking position. The electric motors 5 are powered by a cable 11 with energy. However, it can also be provided that the motors 5 are supplied with energy via batteries.

As in particular from Fig. 3 can be seen, an inner side of the lock body 8 is shaped so that the electric motors 5 and the bushes 12 and thus also the threaded spindles 4 and the locking elements 3 can first be placed in predetermined by projections and recesses in the lock body 8. In addition, recesses and projections for the switch 6 and the sensors 7 are provided. These elements can thus be first inserted without tools in the lock body. Like from the Fig. 5 can be seen, projections and recesses are also formed on the inside of the lid 10, which correspond with the inserted into the lock body 8 elements. These elements are by tightening the lid 10 on the lock body 8 in position fixed.
