Abstract
A temple end piece for a temple of a spectacle frame is comprised of a first segment running essentially straight in the longitudinal direction of the temple, a connecting segment extending downward from the first segment, and a fitting segment intended for fitting on the head and/or behind the ear. The longitudinal fitting segment is borne and supported by the connecting segment, whereby this support is achieved at the longitudinal middle or at the lower end or in the region between the longitudinal middle and the lower end of the fitting segment, so that at least the upper half of the fitting segment projects freely upward to the first segment and can be deflected elastically in the direction toward the connecting segment. This capability of an elastic deflection is furnished by a suitable choice of material, as, for example, a suitable plastic material, and/or specially designed elastic regions. The upper end of the fitting segment is in interconnection with the first segment in such a manner that the deflection movement is unimpeded in the desired degree while simultaneously the first segment is enclosed by the upper end, so that the upper end can form no hook-like tips and is,…
