1. A handle consisting of:
a gripping knob internally provided with a cavity for housing a pin, said pin consisting of at least a larger-diameter cylindrical portion and of a smaller-diameter cylindrical portion projecting therefrom at one end, and of a third cylindrical portion projecting from an opposite end of said larger-diameter cylindrical portion, and of a head retaining member disposed at a top end of said third cylindrical portion and having a larger diameter than that of said third cylindrical portion; an elastic bush, comprising a cylindrical “C”-shaped geometry defined by a slit extending along a longitudinal axis of the bush, that is snap-fit and rotationally housed on said third cylindrical portion, wherein insertion of the pin and elastic bush into the cavity of the gripping knob causes the elastic bush to be in forced, integral engagement with an inner surface of said knob at an annular choking of the cavity to thereby make an integral structure that enables relative rotation between the integral structure of the gripping knob and elastic bush, and the third cylindrical portion; and a washer rotationally housed on said third cylindrical portion and interposed between said head retaining member and said elastic bush, whereby contact between said elastic bush and said head retaining member occurs through the washer, wherein the washer consists of polyamidic resins that minimize rotational friction between said head retaining member and said elastic bush. |
