Abstract

The screw consists of a threaded shank (4) with an e.g. rounded head (4) and a second head (7) with screwdriver groove. The two heads (5, 7) are separated by a short shank (6) with a weak point. After insertion of the screw and first head into the wall (1) and plug (2), the second head is removed using wire cutters.

Description

Die Erfindung betrifft eine Schraube, die man zwar einfach eindrehen kann, dann aber so sichern kann, daß ein Herausdrehen sehr erschwert wird.The invention relates to a screw that you can simply screw in, then but can ensure that unscrewing is very difficult.

Derzeit werden zum Beispiel Schutzgitter, etwa an Kellerfenstern, meist mit Schrauben, die in Dübel gedreht werden befestigt.For example, protective grilles, for example on basement windows, are usually included Screws that are turned into dowels are attached.

Mit geringen Mitteln kann ein potentieller Einbrecher diese Schrauben wieder entfernen, bei fachmännischer Montage würde mindestens der Schraubenkopf verschweißt, eine Möglichkeit die dem Heimwerker kaum zur Verfügung steht.With little means, a potential burglar can fix these screws again remove, with professional installation at least the screw head welded, a possibility that is hardly available to the handyman.

Der Erfindung liegt die Aufgabe zugrunde eine Schraube herzustellen, die nach dem Hereindrehen auf einfachste Weise so verändert wird, daß ein Herausdrehen zumindest erheblich erschwert wird.The invention has for its object to produce a screw according to the Screwing in is changed in the simplest way so that unscrewing at least is made considerably more difficult.

Erfindungsgemäß wird eine Schraube hergestellt, der nach dem Hereindrehen der Kopf entfernt wird. Sei es durch abzwicken, abbrechen, absägen usw. Auf jeden Fall mit einfachsten Mitteln.According to the invention, a screw is produced which, after screwing in the head Will get removed. Be it by pinching, breaking off, sawing off, etc. In any case with simplest means.

Ein potentieller Eindringling benötigt nunmehr einen erheblich höheren Aufwand um diese Sicherung zu überwinden.A potential intruder now requires a lot more effort to overcome this backup.

Die Zeichnung zeigt das Prinzip der Erfindung. Hier bedeuten 1 das Mauerwerk, 2 den eingesetzten Dübel, 3 ein zu befestigendes Teil, 4 Schaft der Schraube, 5 Befestigungsscheibe, 6 Sollbruchstelle und 7 den eigentlichen Schraubenkopf. Dieser kann beliebig gehaltet sein, im Beispiel ein Sechskant. Nach dem Hereindrehen der Schraube wird am Punkt 6 der Kopf weggebrochen oder anderweitig entfernt. Die jetzt haltende gewölbte Scheibe 5 wird nur sehr schwer herauszudrehen sein.The drawing shows the principle of the invention. Here 1 means the masonry, 2 the dowel used, 3 a part to be fastened, 4 shaft of the screw, 5 fastening washer, 6 predetermined breaking point and 7 the actual screw head. This can be anything, in the example a hexagon. After screwing the screw in, the head is broken off at point 6 or otherwise removed. The now arched disc 5 will be very difficult to unscrew.

Claims (1)

Befestigungsschraube dadurch gekennzeichnet, daß nach dem Hereindrehen der Schraubenkopf entfernt wird und somit eine gewisse Sicherheit gegen das Herausdrehen erzielt wird.Fastening screw characterized in that after screwing in the screw head is removed and thus a certain security against unscrewing is achieved.
