Description

The invention relates to a device for securing rotating and / or tilting elements, preferably windows or patio doors, the device being made of there is at least three parts movable relative to each other. The invention relates also a method for operating such a device.

Such devices, which are also referred to as locking devices, are known in principle and are preferably used as additional burglar protection for windows and doors. From DE 296 21 348 , for example, a locking device is known in which two components can be locked to one another via a rotatable bolt.

Known locking devices of the generic type all have the Disadvantage that they build high, since the locking elements are housed must, especially if a cylinder lock is additionally provided to the locked locked position.

The object of the invention is to provide a device which enables effective protection against unauthorized opening of doors and windows and automatically jumps into its locking position after an actuation process of the door or window, the device being universally applicable and the known disadvantages of a simple construction be excluded.

The achievement of the object by the invention is characterized in that a first plate is displaceable relative to a second plate and is movable from a first to a second position, the first plate being fixable in its second position and automatically actuated by an actuating element first position is displaceable. This solution has the particular advantage that the plate construction means that sheets are used which can be produced on the one hand by inexpensive forming technology and on the other hand are extremely flat. The displacement path is chosen so large that the journals on the first plate disengage from the counter bearings of a third plate.

The first plate is advantageously displaced via an actuating device, which can be covered with a blind plug. On the the actuator opposite side a push rod can be arranged whereby the first plate can be operated via a central point. This will make it For example, the device can also be used for skylights bring. Is instead of the blind plug on the trained as an operating button Actuator attached another push rod, several Locking elements are interconnected. When using for However, skylights must have a suitable joint in the push rod become.

It is also conceivable not to actuate the first plate manually via the actuating device but use a motor for this. On Motor has the advantage that it provides the forces for both directions of movement can, so that the spring elements described above are not necessary are. For safety reasons, a motor-driven one can also be used Device which have spring elements, even in the event of a power failure to be able to actuate the device.

According to a further development, the second plate is provided with at least one bend, by moving the two plates in a non-predetermined manner, z. B. is prevented by means of a wire from the outside with the window tilted. This Bending is at an angle of 80 ° to 100 °, preferably 90 °, to the board level of the second plate. As a further safeguard against this Moving means for wedging are partially provided in the first plate. These means advantageously act in the direction of the second plate. Preferably the insertion of cutting edges has proven itself here, but it is also conceivable to use tooth-like embossing or the like.

When trying to open in the manner described above, the claws Means of the first plate with the second plate in the first step by friction. at If further force is applied, there is a positive fit, so there is a shift effectively prevented.

All plates are particularly narrow, so that they can be installed on all common Frame sizes is made possible. An additional advantage is the choice of material, which consists of a hardened or hardenable metal. So it will possible, for example, to harden the second plate and thus manipulation difficult from the outside. As such, e.g. B. conceivable, via a pen or try another pointed object, the two plates gradually to move against each other. Furthermore, it is possible to add other parts of the device to harden. Material fatigue, as can occur with castings, is restricted.

Since the two plates are moved against each other, it can also be made larger Distance the position of the actuator and thus an unlocked or locked position can be determined. By appropriate color design this effect is intensified in the actuating device. The device can by suitable panels are disguised, which in turn in different Colors are conceivable and the color can be adapted to the frame.

The device has the particular advantage that for pure rotary movements of the rotating / tilting element, no actuation is required.

In the method according to the invention, a first plate is moved in Displacement direction provided from a first position to a second position, wherein the displacement of the first plate takes place relative to the second plate, and the first plate in its second position preferably held by spring means becomes.

After opening the rotating / tilting element, the first plate forcibly moved to a third position that is relative to the second position is offset by approx. 3 mm; In this third position too, the first plate is preferred held by the spring means. In a subsequent closing process of the rotating / tilting element, the spring means is forcibly raised, whereby the first plate is unlocked from its holding position, the third position and thus from the third position to the first by means of the second spring means Position, i.e. the starting position, jumps. There is therefore an automatic Lock the device.

The displacement of the first plate can also be carried out using a motor; the motor moves to its starting position after the actuation process back, allowing the first plate to spring back. this has the special advantage that, for example, even after a power failure is that the locking device springs into its locked position. But it is also conceivable to move the motor all the first Let the plate run out and thus do without the spring means. As In addition, the motor can be controlled via remote control and thus also the use of the locking device, for example on skylights from Shop windows are guaranteed.

Figure 1 shows a perspective view of the device, a first Plate 1 is slidably arranged on a second plate 2.

The first plate 1 is in a second position B, in which the journal 9a with counter bearings 9b of a third plate 8 are disengaged. One here as a leaf spring formed spring means 7, which is firmly connected to the first plate 1, is supported on a projection 11 (Figure 2) of the third plate 8 and holds the first plate 1 in position B.

When the rotating / tilting element is opened, the spring means 7 forcibly lifted off the projection 11 on the third plate 8. The first Plate 1 shifts due to a spring means designed here as a tension spring 10, relative to the second plate 2 by about 3 mm, the first plate 1 in one Position C is held, since the spring means 7 is now on the projection 12 second plate 2 supports. During a subsequent closing process of the rotating / tilting element the spring means 7 reaches the projection 11 of the third plate 8, since the first plate 1 is now shifted relative to the third plate 3 by approximately 3 mm is, and is forcibly lifted, whereby the spring means 7 on the projection 12 disengages and due to the spring means 10, the first plate 1 in their starting position, a position A, can reach.

The second plate 2 has bevels 5. This will provide further protection reached because it z. B. is no longer possible, the two plates 1 and 2 with one to move thin wire relative to each other.

On the first plate 1 cutting 6 are arranged as a means for wedging in the event of a manipulation attempt, moving the two plates 1 and 2 make relative to each other more difficult because these cutting edges 6 in the second plate 2 can first wedge frictionally then form-fit.

The first plate 1 is provided with an operating button 3. To connect for example two devices is a push rod 4 on the lower side the first plate 1 is shown schematically. This can also be used for central control respectively.

Figures 2 and 3 show a bottom view of the locking device from of the two supports (projections 11 and 12) of the spring means 7 to the Plates 8 and 2 are clearly visible. The position B is shown in FIG. 2, the spring 7 is supported on the projection 11 of the third plate 8. After opening, for example the window, the spring 7 lifts off the plate 3 and the Plate 1 jumps due to the tension spring 10 until the spring 7 on the projection 12 of the plate 2 supports, as shown in Figure 3.
