Turning knob

摘要

The knob has a spring (22) i.e. spiral spring, biasing a handle in a disengaged position and a base part (15) linked with a valve of a gas cooker to control flow of gas. A link and a crank element (11) i.e. shaft, communicate with each other in an engaged position of the handle part, and the handle part stops against the action of the spring in the engaged position. Rotation axis of the crank element in a plane (31) is perpendicular to a rotation axis (6) of the handle part. A slot (27) is formed in the base part and a slide in the handle.
