Heinrich Peter Daniel in! Hingen, district of Ottweiler. Safety bolt.

Patented in the German Empire on March 24, 1923.

The object of the invention is a security lock against break-in, which is in the locking layer by an automatically resilient and engaging in a hole in the bolt Snap pin is secured, which is triggered by a socket wrench. The subject of the invention differs from known devices of this type in that the snap pin is rotatably displaceable in a guide sleeve with an angled slot stored and so inevitably connected to a coil spring that a The same arranged locking pin -n closed position of the bolt constantly engaged is held with the angle slot. Closing the bolt back is only possible with

a special key suitable for this purpose with the same slidable in a Lämgsbohrung Push pin possible.

The subject of the invention is illustrated in the drawing in an exemplary embodiment, namely show:

Fig. Ι the safety bar with inserted key, partly in longitudinal section, and

Fig. 2 the same in view from the side. An α by the bolt plate through cross locking pin with clearance b B and b ': c stands under the action of a helical spring is concealed within a guide cylinder d and communicates with a hole in the bolt engaging in e. The sheet metal cylinder d is riveted, welded or soldered to the locking plate α. A key guide eyelet / is screwed into the bolt hole. The snap pin b is firmly connected to the helical spring c , which is also attached to the cylinder base d 'with counter-tension. A locking pin b on the snap pin also screwed h, in a

^a 5 angle slot /, Ϊ of the Blechzyliruders d is guided. The upper end of the snap pin b is offset square and is used to attach a security key. /. The safety key is a simple socket wrench / in whose longitudinal bore a pressure pin k is slidably mounted.

The handling is as follows: When the bolt e is pushed forward, the snap pin b automatically snaps into the bolt hole enclosed by the eyelet / 'due to the spring pressure (Fig. I). The bolt is locked in its advanced position.

To close the bolt, the socket wrench / is placed on the square neck on the snap pin b and the latter is turned clockwise by turning the key a quarter turn. In this position, the locking pin Ii has stepped out of the horizontal part i ' of the angled slot and can now be triggered by pressing the key pressure pin k out of the bolt e . The bolt can now be pushed back. The bolt is secured automatically when it is moved, as described.

Claims (1)

Patent claim: Safety slide bolt, which is secured in the closed position by an automatically spring-loaded snap pin which engages in a hole in the bolt, which is triggered by a socket wrench, characterized in that the snap pin (b) is in a guide sleeve (d) with angled slot (i, ϊ) rotatably mounted and is inevitably connected to a helical spring (c) in such a way that a locking pin (h ) arranged on the snap pin (b ) is constantly held in engagement with the horizontal part d ') of the angle slot in the closed position of the bolt (e), so that a shift of the bolt is only possible if the locking pin (A) with the socket wrench (j ) rotated out of the horizontal slot part (1) and the snap pin (b) then moved in the vertical direction by a pressure pin (k) stored in the key shaft will.
