Abstract

A screw securing means serves, according to the invention, to prevent protective grilles for buildings from being removed without authorisation. A washer with spanner surfaces is provided at the head end of a screw with hemispherical head. A bore with a grooved pin is fitted transversely to the washer and to the screw. The grooved pin serves to transmit the torque which results from tightening the washer with spanner surfaces. After the screw has been tightened the grooved pin is driven in deeper by striking it, with the result that torque can no longer be transmitted via the washer.

Description

Der Erfindung liegt die Aufgabe zugrunde eine SchraubensicherungThe invention is based on the object of a screw locking device

zu entwickeln, die mit herkömmlichen Normteilen ohne Sondermaschinen und Sonderteilen hergestellt werden kann.to develop that with conventional standard parts without special machines and special parts can be produced.

Die Schraubensicherung wie sie Fig. 1 und Fig. 2 darstellt, läßt nicht mehr zu, daß etwa der Stift 3 mit einem Durchschlag wieder in eine Position gebracht werden kann, daß die Schraube 1 aufgedreht werden kann.The screw lock as shown in Fig. 1 and Fig. 2 does not allow more to the fact that about the pin 3 brought back into position with a punch can be that the screw 1 can be unscrewed.

Der Erfindungsgedanke liegt darin, daß der Stift 3 nicht mehr durchgeschlagen werden kann.The idea of the invention is that the pin 3 is no longer punched through can be.

Bei einer durchgehenden Bohrung könnte der Stift durchgeschlagen werden und jedem wäre es möglich einen neuen Stift einzuschlagen und die Schraube aufzudrehen.If the hole is drilled through, the pin could be punched through and everyone would be able to drive in a new pin and unscrew the screw.

Dies ist aber nach der Erfindung in Anspruch 1 - 3 nicht möglich.However, this is not possible according to the invention in claims 1-3.

Fig. 1 zeigt 1 Schraube mit halbrundem Kopf.Fig. 1 shows 1 screw with a semicircular head.

2 Scheibe mit Schlüsselflächen.2 washers with wrench flats.

3 Stift in oberer Stellung zur Übertragung eines Drehmomentes. Fig. 2 zeigt 3 Stift in unterer Position Scheibe mit Schlüsselfläche läßt sich in dieser Position drehen.3 pin in the upper position for the transmission of a torque. Fig. 2 shows 3 pin in the lower position. Disc with wrench flat can be inserted in this Rotate position.

Claims (3)

Patnntansprüche 1) Schraubensicherung insbesondere zur Befestigung von Bautenschutzgitter und sonstigen Gegenstände, dadurch gekennzeichnet, daß quer zu einer vorhandenen Schraube 1 und einer Sechskantscheibe 2 ein Stift 3 vorhanden ist, der zunächst nur soweit wie in Fig. 1 dargestellt ist eingeschlagen wird, daß die Schraube 1 angezogen werden kann und der Stift den Drehmoment überträgt. Claims 1) Screw locking especially for fastening of building protection grids and other objects, characterized in that transversely A pin 3 is available for an existing screw 1 and a hexagon washer 2 is, which is initially taken only as far as shown in Fig. 1 that the screw 1 can be tightened and the pin transmits the torque. Nach angezogener Schraube 1 wird der Stift 3 Fig. 2 bis an die Innenwand der Scheibe 2 eingeschlagen, sodaß sich die Scheibe 2 frei drehen kann. After tightening screw 1, the pin 3 Fig. 2 is up to the inner wall the disc 2 struck so that the disc 2 can rotate freely. 2) Schraubensicherung nach Anspruch 1 dadurch gekennzeichnet, daß die Bohrung für den Stift 3 nicht durchgebohrt ist.2) screw locking device according to claim 1, characterized in that the hole for pin 3 is not drilled through. 3) Schraubensicherung nach Anspruch 1 dadurch gekennzeichnet, daß die Scheibe 2 Sechskant-oder Vierkant- Mutter- ähnlich ohne Gewinde ausgebildet ist.3) screw lock according to claim 1, characterized in that the washer 2 hexagon or square nut is designed similarly without thread is.
