Abstract

986,866. Artificial limbs. HUGH STEEPER Ltd. Aug. 6, 1963 [Aug. 9, 1962], No. 30595/62. Heading A5R. Means for locking and unlocking an elbow joint with alternate pulls on a control cord comprises a pivoted member which is rocked between two positions in one of which it allows a detent to engage a locking quadrant while, in the other, it holds the detent disengaged. When the cord 5H, Fig. 1, is initially pulled, a lever assembly 5 is raised about a pivot 5D and lifts a spring-loaded detent 3C clear of a toothed locking quadrant 3K attached to the forearm 3L. This allows a spring-loaded latch 4A to turn counterclockwise about its central pivot so that its upper surface engages beneath the detent 3C and holds it raised. On subsequent release of the cord 5H the latch 4A is prevented from turning by the detent 3C and its rear surface 4C engages the right-hand pin on a sliding member 6, Fig. 2, which it moves to the right. The subsequent pull on the cord 5H, Fig. 1, consequently brings the lefthand pin under the beak on the member 4C and causes it to tilt clockwise and disengage detent 3C which is, however, still held by the lever 5. However, final release of the cord 5H allows it to drop into engagement with the locking quadrant 3K while the left-hand cam surface on the pivoted member 4C moves the slide 6 back towards the left.
