The present invention relates to a method of manufacturing a resilient knob by injection molding.

Method of manufacturing an improved knob by injection molding

An improved knob for attachment to a lever or the like having a knob body with a cavity formed therein, an extension operatively attached to the body and being biased toward the cavity. Operatively attached to the extension is a projection for engaging a mating portion on the lever and a tapered portion for enabling the knob to be easily removed from the lever. The preferred knob has the extension connected to the knob body so that the extension does not project very far below the cavity entrance. The knob of the present invention is preferably manufactured by injection molding in a single step operation. Once cured, the knob is removed from the mold in condition for assembly on an appropriate lever or the like. To effectuate assembly, an assembler simply places the knob on the lever or the like until the projection engages a mating portion thereof.
