EP2594724B1 - Door or window that prevents break-in - Google Patents

Description

The invention relates to a burglary-resistant door or burglar-resistant window according to the preamble of claim 1.

For the purposes of the present application, the term frame comprises both profiles composed of frames and door frames.

State of the art

In order to gain access to locked buildings, burglars usually seek to reach the rebate area or rebate chamber of a door by manipulating elongate tools such as a crowbar, wedge, screwdriver, or drill to manipulate locking elements or gear elements located there or to pry the sash out of the frame. The folding region or folding chamber is understood to be the region between mutually facing folding walls of the casement frame and of the window frame, in which locking and gear elements and their actuating elements (for example push rods) are typically arranged.

US 4741277 discloses an anti-burglary door or window according to the preamble of claim 1.

EP1275798 discloses the placement of a ledge in the rebate area of a door or window that is transverse to the plane of the panel.

Many burglar-resistant doors or windows are known from the prior art, the sash, for example, with additional locking elements, which are distributed over the circumference of the sash at certain points, are anchored to the window frame, so that a violent opening of the door or the window is difficult. As a result, while the overall burglar resistance of the door or window is increased, but a large part of the rebate between the sash and frame remains "unprotected". Especially with doors or windows that can be converted into a tilted position, there is the further problem that a tilted sash can be manipulated more easily.

task

Accordingly, it is an object of the present invention further develop a burglar-resistant door or a burglar-resistant window of the type described above in terms of improved burglar resistance.

solution

This object is achieved according to the invention by an anti-burglary door according to the characterizing part of claim 1.

The strip, which extends along the fold and protrudes over a certain depth in the folding chamber due to its elongated cross section, prevents access to the folding chamber, even if the attack side facing the sash has been damaged. In particular, a crowbar or the like can no longer be guided into the area between the window frame and sash without first bumping against the bar, so that no leverage can be applied to the sash. In order to manipulate the door or the window in the area of the bar, the bar must first be destroyed or removed as such, whereby a lot of time is lost to an unauthorized person. This is especially true for tilted casement, since the bar blocks due to their orientation even then access to the rebate area.

The use of a drill remains unsuccessful in a break-in attempt due to the aligned across the filling bar, since the drill, which must be performed approximately parallel to the bar, hooked with the bar. In particular, the fact that the free portion of the ledge, which has minimal flexibility due to the elongated cross-section of the ledge, causes a drill to become entangled with its cutting edges.

The arrangement of the strip is therefore not a protective device that acts selectively, but rather over a certain length. In this case, the inventive Bar are arranged, for example, in the region of the castle, so that it prevents in particular a manipulation of the castle. On the other hand, it is possible in a simple manner to provide the bar according to the invention almost along the entire length of a frame leg, for example on the lock side of the door, so that access to the fold area over the entire height is considerably more difficult in the closed state of the door there. Also, the upper horizontal fold of a door or the legs of a window can be effectively protected. To provide the strip along an entire fold of a door leg, a correspondingly long trained bar is provided.

If the at least one strip anchored in the frame leg, there is the advantage that the strip is anchored on the side facing away from the outside of the folding area, which is difficult to access for the purpose of manipulation, since it is covered by the sash.

Advantageously, the at least one strip is glued or pressed into the anchoring groove and / or connected by means of a pin or screw connection with the associated frame leg or sash leg. In this way creates a stable connection between the bar and associated frame legs.

In the event that the at least one strip is pressed into the anchoring groove, it is particularly advantageous if the anchoring groove or the anchoring portion of the strip is provided with a structuring on the surface, so that between the at least one pressed bar and the anchoring a Form fit exists. In this case, the structuring, for example, consist of projecting barbs or noses, which can be created in an easy way as integral components, for example, in the extrusion of the components.

In order to increase the burglar resistance further, it is provided according to an embodiment of the invention that a preferably designed as extruded aluminum frame Blendrahmenschenkel and / or a likewise executed sash leg is provided with at least one chamber in which at least one insert is arranged. As a result, the resistance of the frame legs against drilling, chiselling and fire is significantly increased. The insert may consist of aluminum, steel, other material or a combination of the aforementioned materials.

If gaps measured between the strip and the at least one insert in the vertical direction do not exceed a dimension of 15 mm, preferably of 12 mm, more preferably of 10 mm, a large-scale burglar resistance in the area of the glare and sash frame is achieved. Furthermore, the door designed in this way also meets high requirements for bombardment.

According to a development of the door according to the invention, it is provided that the fold is deflected twice by approximately 180 ° and / or runs in an S-shape. This geometry hinders the insertion of the tools provided for manipulating the door.

The frame legs and / or the sash legs can be composed according to a further embodiment variant of an inner frame profile and an outer frame profile and an insulating profile connecting the two frame profiles, wherein the at least one bar is arranged in one of the outer frame profiles.

According to the invention, the at least one bar made of stainless steel, high-carbon steel, ceramic or a metal-ceramic composite. It is particularly advantageous if the material of the strip has a minimum tensile strength of 500 N / mm ² , preferably of 600 N / mm ² , more preferably of 800 N / mm ² , and / or a minimum hardness of 150 HB, preferably of 180 HB, more preferably of at least 220 HB.

The cross section of the at least one strip should advantageously have a length between 150 mm and 2500 mm and / or a width between 15 mm and 25 mm, wherein the thickness of the strip should be at least 1.5 mm, preferably 2 mm, more preferably 3 mm , A bar with a length of about 150 mm is suitable for protecting the lock with the latch and bolt of a door or the locking of a window.

In this case, the cross section of the at least one strip should be formed to a proportion of between 30% and 70%, preferably between 40% and 60% of the anchoring portion, so that on the one hand there is a stable anchoring of the strip and on the other hand a sufficiently long free section, the - as already explained before - due to its minimal flexibility the use of drilling effectively prevented or difficult. Also, the free portion should be long enough so that the bar in the tilted state of a sash also provides a barrier against the penetration into the rebate area.

Finally, it is advantageous if strips are arranged both in the rebate on the lock side and in the rebate in the region of a horizontal frame leg or a horizontal sash leg.
