Knob

Abstract

A molded knob of the type which frictionally engages and slips over the end of a shaft. The knob has a hub with a shaft receiving socket formed therein. The socket has a flat wall adapted to engage a flat on the shaft. Elongated fingers which are formed as part of the hub extend into the socket on the opposite side of the socket from the flat wall. The fingers extend towards and are aligned with each other. They are laterally deflectable away from the flat wall of the socket upon insertion of the shaft into the socket. An abutment is located at the base of each finger. One of the abutments is engageable with the shaft when the shaft is rotated to limit further deflection of the fingers by the shaft due to twisting caused by the application of torque to the shaft. In a modified form, a stop is provided to engage the fingers to limit the amount of deflection of the fingers in place of the abutments.
