Description

The invention relates to a device for the aggravation of thefts.

There are a myriad of ways to make it difficult for thieves to break into work and disrupt their work. This starts with the grating of windows and ends with the television observation and the electronic alarm. Therefore, thieves are dependent on doing their work as quickly as possible and then disappearing as unrecognized as possible with their stolen goods as quickly as possible.

So far, interesting objects are rarely mounted on thieves so firmly at their site that the disassembly takes considerable time for thieves. This is only common with vaults that are walled into a wall or attached to a brick wall with dowels and screws. Precious antiques, often much more valuable than the contents of a vault, are usually unsecured in apartments. In museums, they are often connected to a reporting device, which should report the removal of an object in a central office. Experienced and specialized thieves are able to shut down such signaling systems. Where this fails, thieves work so fast that the items are removed before museum guards or police officers can access them.

For such heavy objects such. As antique cabinets, there are only a few ways out of their own weight and possibly their attachment with screws on their installation site behind the final wall, to hinder the removal by thieves.

From the US 4,184,277 A a device is known by means of a name plate can be locked by magnets. The rightful owner of the name tag knows the fact that a magnet must be used, but not an unauthorized person, so that the name tag is protected against unauthorized removal. A disadvantage of such a system is that the protection can be overcome with a sufficiently strong magnet in a very short time.

From the US 5,979,196 A For example, there is known a device for protecting flexible material, such as clothing, in which an individual key must be used to overcome the holding force that engages a securing element. A disadvantage of this system is that it has tapered guide elements. Although this is advantageous for quickly releasing the device of textiles, but when attaching heavy objects, such as furniture, this means that they would have to be positioned with usually not achievable high precision for the device to work safely. It is another disadvantage that the system inevitably has to be equipped with an elaborate key that can be lost. It can then happen that even the rightful owner can not move the object.

It is the object of the invention to provide a simple way to attach objects at the location of their installation so releasably that they are difficult to extract without tools from their attachment again.

The invention solves the problem by a device according to claim 1.

These panels allow attachment of the object to be protected to the wall or floor without preventing their removal from the site of the rightful owner. It only takes time, a knowledge of the attachment of the plates and some skill to separate the two plates again. Since time is of less importance to the rightful owner of the protected objects than to thieves, the objects to be protected against theft are afforded good protection by the device according to the invention. In this way, standing on a wall or hanging objects well secure, but also on the floor standing objects.

The tool for releasing the two plates from each other may be a pin, which preferably has at its end immersed in the channel a wedge-shaped chamfer, with which the movement of the two plates against each other preventing spring can be lifted out of its seat.

The tool may also be a key with a key bit, which has a projection located at the level of the spring, wherein the channel is formed as a key guide.

This device is simple in construction and easy to handle when the spring is a flat steel or a spring steel pin.

In this device, it is expedient if the guide is a dovetail.

For securing wall-mounted furniture or hanging on the wall picture frame, it is expedient if at least one plate is provided with at least one hole for the insertion of a screw.

It is advantageous if in the middle of at least one plate between the lateral guides a free space is located whose depth is greater than a screw head depth so that screw heads do not hinder the displacement of the two plates against each other.

When mounting the plates, it is advantageous if one and / or both plates are provided with a slot for the insertion of a mounting option.

If the object to be protected has a not inconsiderable width, as is the case with a cabinet, for example, it is expedient to secure it by two plate pairs to be arranged at a distance from one another. It is advantageous if the two plate pairs have 90 ° twisted axial directions.

For reasons of safety, it is advantageous if the two plates guided into one another have the same external dimensions.

In order to enable attachment to objects without screws, it may be advantageous to roughen or corrugate at least the surface of the one plate or to perform with dovetail-like depressions for receiving an adhesive.

In the embodiment of the device, it is advantageous if the channel is reversibly closed. If the thief is aware of the mechanism of the device, it is still prevented by the closure of the channel from triggering in a short time the mechanism for moving the two plates. In this case, the channel may be closed by the fact that at the upper part of the channel a thread for screwing the channel opening is arranged or that the channel is closed by a plug.

The essence of the invention is explained below with reference to an embodiment schematically illustrated in the drawing. Show it:

1 an end view of the device,

2 a view of a plate,

3 a view of the other plate,

4 another embodiment of the device,

5 a further embodiment of the device,

6 to the device of 6 belonging pen.

The device consists of two plates 1 . 2 , which by a guide in the form of a dovetail joint 3 are connected to each other so that they are axially against each other in one direction. Both plates are with holes 4 provided for the acceptance of screws or screw heads.

The axial displacement possibility of the two plates 1 . 2 against each other is bounded in two directions, in one direction by pins 5 which are inserted into the one plate and abuts against a recess in the other plate. These pens 5 are used so that when pushed together plates 1 . 2 the faces of these plates are aligned. These pens 5 are immobile and permanently used. In the other direction is the movement of the plates pushed one inside the other 1 . 2 through a spring-loaded pin 6 Lockout. This lock can be inserted into the channel (hole) 7 introduced, preferably with a frontal bevel 8th provided pin 9 pick up so that the two plates are not in through the pins 5 Locked direction are displaced.

In the embodiment of 3 is the spring-loaded movable pin 6 made of spring steel. With his right end he is in a hole in the plate 1 inserted and extends with its left end into a recess 10 in the other plate 2 , With the help of in the channel 7 introduced, with the bevel 8th provided pin 9 is the pen 6 in the direction perpendicular to the paper plane out of the recess 10 heraushebbar, so that now the one plate 1 against the other plate 2 not by the pins 5 Locked direction is axially displaceable.

In the embodiment of 4 is that in a hole 11 inserted pen 6 made of spring steel by one in the channel 7 introduced pen 9 pivotable in the plane of the paper, whereby it can be pivoted out of its locked position

In the embodiment of 5 is one with a hole 12 provided pin 6 against the force of the spring 13 with the help of a pen 9 in the canal 7 is inserted and into the hole 12 introduced, herausdrückbar from its locked position.
