Description

Burglar alarm against prying out of single or double-leafed, inward

rising windows

The invention relates to an anti-burglary protection against levering of single or double leaf, inwardly rising windows in which in the fitting groove of the sash a per se known rod closure is arranged, which has at the locking point projecting pins or bolts which engage in suitable closing parts in the frame while moving the pins or bolts to the left or right or up or down to close the window.

To protect against burglaries, it is common to use alarm systems. These respond when a door or window is opened, a light barrier will pass or the like.

An anti-burglar alarm of this type with a sensor is described in EP 0 831 442 B1. The use of such burglar alarms burglary and theft can not be prevented, since valuable time elapses until the arrival of the guard.

In DE 196 20 048 AI an anti-burglar is described in which in the burglar protection attached to the Stülp housing is disposed in the wing, in which a slider is inserted into the locking rod, so that the engaging in the actuating slot actuating pin on the short leg of an angle plate which is pivotally mounted in the housing, and on the long leg of the angle plate, a drive pin is seated, which engages in the locking pin. So it is installed an additional backup in the locking system.

A disadvantage of this prior art is that the drive rod coupling device, consisting of the driving element and the driving projection in the folding air is slidably disposed and forms an additional component, which unnecessarily expensive the espagnolette fitting. This burglar alarm is therefore very complicated.

In the event of break-ins, an attempt is often made to attach a crowbar to the closing units between the window frame and the window frame in order to pry the window frame out of the closure.

In DE 197 30 033 AI a solution is proposed in which the lying between the frame and the associated sash Falzluftbereich is provided with an impact resistant and mechanically resistant filling, which extends at least on the side of the adjacent Falzluftraums to the inner wall of the local connecting web and themselves extends across the cavity to the inside of the opposite connecting web.

DE 10 2004 030 013 AI describes an anti-burglar alarm for a door, in the band side on the door and the door frame continuous security profiles are provided in each case, which engage in the closed state of the door in full length. The decisive disadvantage of these safety profiles is that a gap remains between the glare and window frame, on which a lever can be attached, with which the window or the door can be levered out.

It is therefore the object of the present invention to propose an anti-burglary, which makes a break through a levering out of windows impossible or at least significantly more difficult.

The object is solved by the features of the first claim. The invention is for single or double leaf, inwardly rising window, in which in the fitting groove of the sash a bar closure is arranged, which has at the locking point projecting pins or bolts, which engage in suitable closing parts in the frame and thereby the pins or bolts closing the window, left or right or up or down, provided. The cavity between the frame and the window sash is filled with a safety block in the region of the latches, wherein the safety block almost completely eliminates the outer gap between the window frame and the frame, so that a possibility of attack from the outside of the window to the moving parts of the window fitting prevented becomes. The safety block can be made of a hard plastic or metal. It can be extruded or glued or screwed in later. It is also possible that the safety block is a hollow body made of a durable material, which is subsequently glued or screwed.

In the context of a particularly simple embodiment, the safety block can be configured and arranged on the closing part such that, for closing the window, the pin or pin enters a recess between the safety block and the closing part. In this case, the pin or bolt - depending on the configuration of the closing part and / or the security block - a linear movement or a quasi L-shaped movement to go through in order to get into the closed position. The security block may have at least one projection.

In one embodiment, the safety block may include two protrusions comprising the closure member. In this case, the safety block can be arranged in the frame in such a way that one projection is in contact with the closing part and the other projection forms the recess with the closing part, which pin or pin is provided with an L-shaped movement. passage. In another embodiment, the safety block may have a projection and the closing part a projection, wherein the projection of the safety block and the projection of the closing part are configured such that in the installed state, the projection of the safety block and the projection of the closing part are arranged together. Such a security block is particularly suitable for double-leaf windows, since two recesses can be formed by the configuration of the security block in conjunction with the design of the closing part, in which each bolt or pin can engage to close the window.

In the context of improved stability of the burglar alarm, an angle piece could additionally be provided which can be connected, for example, to the safety block and / or to the window frame, so that it can be screwed or glued to the safety block and / or can be screwed or glued into the window frame. However, other types of connection are possible. Additionally or alternatively, the safety block could be connected to the elbow and / or one leg of the elbow in the installed state flat, preferably all over, abut the closure member. To further stabilize the elbow could have a longer and a shorter leg, wherein preferably the longer leg is connectable to the frame and the shorter leg surface, preferably the entire surface rests against the closure member and / or also with this is connectable. The safety block could then be connectable to the frame with the longer leg or through the longer leg. As a result, the breaking out of the closing part could be made more difficult.

Burglars first try to find the locking points to attach a lever tool in these places, which releases the window or the door from the lock. The key advantage of the invention is that in the areas of the lock the penetration of sharp tools for levering the window or door is prevented. The safety block is simple and inexpensive to manufacture and can also be used to retrofit existing windows and doors. It is important that the air gap between the frame and the window frame at least in the region of the lock is completely eliminated.

The invention will be explained below using an exemplary embodiment. Like reference numerals in the several drawings indicate the same or similar parts. Show it:
