Abstract (en)
A flush rotary control knob for use with gas taps which include niting, comprises a pair of opposed generally cylindrical members 1,2 each having a plurality of axially disposed fingers 3 spaced around the circumference thereof, the fingers 3 of one of the members 1,2 intermeshing with the fingers 3 of the other of members 1,2, and a rotary member 4 disposed inside the fingers 3 and having a circumferential surface 6 adjacent a circumferential surface of the fingers 3. The rotary member 4 is provided with a continuous cam track 7 in its circumferential surface 6 and each of the fingers 3 is provided with a cam follower peg 8 which extends into the cam track 7. A compression spring 5 is provided to bias the opposed members 1,2 apart. Axial movement between the opposed members 1,2 causes the rotary member to rotate to retain the control knob in retracted and extended positions and also in an intermediate position which is used to overcome the niting of the gas tap.
