Abstract

1383438 Crank handles G F GIEBLER 27 Jan 1972 [28 Jan 1971 5 March 1971] 3843/72 Heading B7E A hand crank comprises a crank arm having a cavity at one end, and an operating knob having a shank rotatably mounted in the cavity, the shank and hand-gripping portion of the knob being formed in one piece of elastomeric material, in which the shank is in rotational contact with substantially the entire length of the cavity wall. The free end of the crank has a cylindrical part 2, Fig. 4, forming the cavity to receive the stem 19 of a knob 15 secured by a moulded flange 20. The knob may be hollow and have its open end closed by a disc 18. In another arrangement, the stem and bore of part 2 have co-operating rib and groove. The stem may have a bore 64, Fig. 10, to receive an expander pin 65. The cavity formed by part 2 may be closed or partly closed at its end remote from the hand-grip part of the knob and be provided with a projection to co-operate with a correspondingly-shaped part of the stem, such as is shown in Fig. 6.
