"Hardware for doors or windows"

j The present invention relates to a

j Hardware for doors or windows in the form of a

Shield or a rosette, consisting of a cover cap and an insert plate arranged in it made of hard material.

Fittings of the generic type, which are also referred to as security fittings, are on known and should serve the purpose of a lock that penetrates the fitting against To secure drilling. "So far one has the insert

Pieces made of hardened metal. This will a considerable protection against drilling into the lock is guaranteed, however drilling through of hardened metal insert plates with high quality tools and with still possible after a corresponding expenditure of time. The present invention is based on the object a fitting of the generic type to

that the insert plate is made of ceramic.

The use of a ceramic insert plate has not previously been used in hardware construction Material - becomes an absolute protection against piercing in a surprisingly simple way a fitting in the lock area prevented, since it has been shown that the insert plate during drilling attempts it may crack, but it can still be pierced, as the individual parts of the cracked Insert plate within the fitting can not move and thus ultimately still Form a closed insert plate that is closed in terms of the intended protective function.

An advantageous further development of the subject matter of the invention is characterized in that the insert plate extends from one to its stop surface Protective cap made of high-strength metal is encased. The main advantage of this measure is that that drilling the fitting in this way additionally is made more difficult. As usual, the outer top cap consists of a decorative material, preferably Light metals.

Another idea of the invention is that the protective cap has several openings with which the through holes of the insert plate are aligned and through the bolts with internal thread ■ are passed, the heads of which are supported on the protective cap.

The bolts with internal threads are used for concealed screwing of the fitting on a door or window and since the heads of the bolts are supported on the protective cap, the loads that arise when the fitting is screwed on are also absorbed by this protective cap.

Further features of the invention are the subject of further subclaims.

Embodiments of the invention are shown in the accompanying drawings and are described in more detail below.

The protective cap 2, which is preferably designed as a pressed part, has one of the number of bolts 4 corresponding number of openings 6 with which ■ through holes 7 within the ceramic made Insert plate 3 in alignment. Through the openings 6 and the through holes 7, the bolts 4 are passed.

The openings 6 are each in the area of the wells 8, the wells 8 having a non-round, preferably have a rectangular plan, as well as the heads 9 of the bolts 4. The heads 9 of the bolts are based on the bottom of the depressions 8 of the protective cap 2 and are preferably out of round due to the rectangular shape secured against twisting.

The bolts 4 are advantageously made of hardened Made of metal.

The exemplary embodiment of the invention according to FIGS. 3 and 4 differs from the one previously described in that the insert plate 3 made of ceramic is made considerably smaller than the overall fitting and is arranged above the opening 10 for a lock cylinder. The insert plate 3 is shown in FIG Embodiment made circular and embedded in a protective cap 2, which is designed here as a cast part.

Since it is essentially important in a security fitting to prevent the so-called Touring pins of a lock can be drilled, it may well be sufficient to use one made of ceramic manufactured insert plate to be arranged partially above the opening 10 for the lock cylinder.

In both exemplary embodiments, the insert plate is completely encased except for its stop surface.
