Description

Sperre für künstliche Hände. Die Erfindung betrifft eine Sperre für künstliche Hände mit einerum, das Sperradlsegment mittels eines auf dessen Achse drehbar angeordneten Hebels ausschwingbar gelagerten Sperrkilinke.Artificial hands lock. The invention relates to a lock for artificial hands with one, the ratchet segment by means of one on its axis rotatably arranged lever swing-out mounted locking pawl.

DasWesenderErfindung liegt darin" daß die Sperrklinke durch Kniehebel und Zugstange mit &m, Sperradsegment in Eingriff kommt, und daß die Sperrklinke durch die Wirkung einer Feder in Eingriff mit den Zähnen des Sperradsegwentes gehalten wird. Ferner wird die Sperrklinke durch Rückwärtsbewegung des Kniehebels gegen einen Anschlag gedrückt, so daß sie außer Eingriff mit den Zähnen des Sperradsegmentes gebracht wird und die öffnungs- und Schließbewegungen der künstlichen Hand nicht behindert werden.The essence of the invention is "that the pawl by toggle levers and pull rod engages with & m, ratchet segment, and that the pawl held in engagement with the teeth of the ratchet wheel by the action of a spring will. Furthermore, the pawl is by backward movement of the toggle lever against a Pressed stop so that it disengages from the teeth of the ratchet segment and the opening and closing movements of the artificial hand are not be hindered.

In Abb. i der Zeichnung ist der Erfindungsgegenstand im gesperrten und in Abb. 2 im geöffneten Zustande dargestellt.In Fig. I of the drawing, the subject of the invention is locked and shown in Fig. 2 in the open state.

Die ganze Sperreinrichtung ist auf einer gemeinschaftlichen Grundplatte, i angeordnet. Das Sperradsegginent 2, an dem auch die Fingerbewegungsstangen 3 angreifen, und der Schwinghebel 4, an dessen frei schwingendem Ende die Sperrklinke 5 ausschwingbar befestigt ist, sind drehbar auf der gemeinschaftlichen Achse 6 gelagert. Der Schwinghebel 4. ist mit dem Kniehebel 7, der auf der Grundplatte i uni den Punkt 8 drehbar angeordnet ist, durch die Zugstange 9 verbunden. Das Zuräckbewegen des Hebels 4 mit der Klinke 5 erfolgt mittelbar durch den Knichebel 7 bis zu dem an der Grund#platte i befIndlichen Nokken io, durch welchen die Klinke 5 außer Eingriff mit dem Sperradsegniente 2, gebracht wird. Die Feder i i, welche an der Klinke 5 angreift, hält, so lange letztere gege#i den Nokken i o anliegt, die Sperre geöffnet, bringt aber auch, sobald der Kniehebel 7 den, Schwinghebel 4 samt Klinke 5 von dem, Nocken io abhebt, die Klinke 5 in Eingriff mit den Zähnen des Sperrsegirne,-ntes:2.The entire locking device is arranged on a common base plate, i. The ratchet segment 2, on which the finger movement rods 3 also engage, and the rocking lever 4, at the freely oscillating end of which the pawl 5 is attached so that it can swing out, are rotatably mounted on the common axis 6 . The rocking lever 4 is connected to the toggle lever 7, which is rotatably arranged on the base plate i and the point 8 , by the pull rod 9 . The lever 4 with the pawl 5 is moved back indirectly by the toggle 7 up to the cam io located on the base plate i, by which the pawl 5 is brought out of engagement with the ratchet 2. The spring ii, which engages the pawl 5 , holds as long as the latter rests against the cams io, the lock is open, but also brings the lock open as soon as the toggle lever 7 lifts the rocking lever 4 together with the pawl 5 from the cam io, the pawl 5 in engagement with the teeth of the locking girne, -ntes: 2.
