Abstract

1,245,651. Artificial knee joints. CHAS. A. BLATCHFORD & SONS Ltd. 24 June, 1969 [26 June, 1968], No. 30454/68. Heading A5R. An artificial knee joint consists of a drum 5A connected to and movable with the lower part of a leg assembly 6, 6B, 6C and a friction band 9 extending around the drum and also around a member 10 adjustably connected to the thigh portion, not shown, of the leg and a pre-set automatic compensating mechanism adapted to apply a substantially constant tension to the band. This mechanism comprises a pre-set clock-type spring 12 coiled around the axis of a rod 11. The member 10 has a threaded bore (10A), Fig. 2 (not shown) therein in which the threaded rod 11 is received via an aperture in the band 9. Rod 11 is rotatable by the spring 12 and the portion 11B of the rod 11 furthermost from the member 10 is of generally square cross-section, and innermost coil 12A of the spring fits closely to the portion 11B. The distal end of spring 12 is anchored to pin 12B fixed in the frame 2 of the leg assembly. The spring 12 is pre-tensioned and exerts a torque on rod 11 in such a direction as to tend to rotate rod 11 so as to move the member 10 upwards, thereby compensating automatically for slackness arising in band 9 owing to wear.
