Description

Auslösevorrichtung für das Schließungsgesperre künstlicher Hände o. dgl. Die Erfindung betrifft eine Auslösevorrichtung für das Schließungsgesperre künstlicher Hände o. dgl. und besteht darin, daß die Sperrklinke, die die künstliche Hand in ihrer Schließstellung hält, mittels eines Zugorgans mit einem um den Körper des Trägers schließbaren Leibgurt verbunden ist, so daß durch einen willkürlichen oder auch unwillkürlichen plötzlichen Ruck des Körpers eine schnelle Auslösung des Schließungsgesperres ermöglicht wird.Release device for the locking device for artificial hands, etc. Like. The invention relates to a release device for the locking mechanism Artificial hands o. The like. And consists in the fact that the pawl that the artificial Hand holds in its closed position, by means of a pulling element with one around the body the wearer's closable waist belt is connected, so that by an arbitrary or even sudden involuntary jerk of the body a rapid triggering of the Closing lock is enabled.

Ein Ausführungsbeispiel der Erfindung ist auf der Zeichnung dargestellt. An dem um den Leib des Prothesenträgers zu legenden Gurt a greift mittels eines Ringes b ein Zugorgan c (Gliedkette o. dgl.) an. Das andere Ende des Zugorgans c ist an der Auslösevorrichtung d der Greiferklaue befestigt, so daß bei eintretendem Zug die die Klauen f zusammenpressende Schraubenspindel e ausgerückt wird. Ein hierbei frei werdender Federdruck treibt die Klauen auseinander.An embodiment of the invention is shown in the drawing. A pulling element c (link chain or the like) engages the belt a to be placed around the body of the prosthesis wearer by means of a ring b. The other end of the tension member c is attached to the release device d of the gripper claw, so that when the train enters the screw spindle e which compresses the claws f is disengaged. A spring pressure that is released here drives the claws apart.

Der Vorteil dieser Vorrichtung beruht also darin, daß bei einem plötzlichen bewüßten oder unbewußten Ruck des Körpers die Arbeitsklaue sich selbsttätig öffnen ünd den erfaßten Gegenstand sofort fahren lassen kann. Auf diese Weise wird der Arbeitende vor der Gefahr geschützt, die unter Umständen durch ein verspätetes Loslassen des ergriffenen Gegenstandes entstehen kann.The advantage of this device is based on the fact that with a sudden conscious or unconscious jerk of the body, the working claw open automatically and can let the detected object drive immediately. In this way, the Workers are protected from the risk of delayed letting go of the grasped object can arise.
