发明名称 A spectacles frame and temple members of the same
摘要 <p>A spectacles frame and temple members of the same are provided, in which the strength of the elastic members is hard to deteriorate even when the spectacles might have been repetitiously worn during a long duration of time and which do not cause large fluctuation in the sense of fitness on the part of the wearers owing to the size difference of the users' heads. A pair of right and left temple members of a spectacles frame, frontal end portions of which members are connected to both ends of a front frame and at a rear end portion of which members each an ear suspension section in abutment with a lateral side of a wearer's head is provided, wherein a temple main body comprises a plate spring section formed to a side of the front frame; and a highly rigid section formed to a rear side of the plate spring section with the ear suspension section inclusive and having bending rigidity higher than that of the plate spring section while the plate spring section is formed in such a manner that its vertical width is rendered constant or tapered with narrowed by a predetermined ratio from its frontal side to its rear side as well as such that a thickness of the plate spring section satisfies the predetermined equation in relation with vertical widths of the plate spring section, positions in a longitudinal direction thereof and an abutment position with the lateral side of the head at the highly rigid section.</p>
