| 摘要 | Pressure means for use with eyeglass frames, including a main support body which snugly fits over the temple portion of the frame, and an elongated spring member held by the support body and shaped to engage the end piece of the frame front when the temple is substantially fully open such that the spring is placed in tension and a pressure is exerted on the temple to urge it towards its closed position. | ||||||
| 权利要求 | 1. Pressure means for an eyeglass frame including a frame front, a pair of temples, and hinge means connecting said temples to said frame front, said pressure means comprising a main body member shaped to fit snugly and removably over one of said temples at a position adjacent the associated one of said hinge means, a receiver member shaped to fit snugly and removably over said frame front at a position adjacent said associated hinge means, said receiver member extending outwardly beyond and in avoidance of said one temple and said associated hinge means, and elongated resilient means supported on said main body membeR and extending forwardly thereof, said resilient means being disposed to bearingly engage an outer end portion of said receiver member only when said one temple is near its fully opened position substantially normally of said frame front to urge said one temple from its fully opened position toward its closed position and into bearing contact with the user''s head. 2. The pressure means as set forth in claim 1 wherein said body member and said resilient means are selectively longitudinally movable with respect to each other and said resilient means is shaped such that said selective longitudinal movement varies the pressure exerted by said resilient means on the temple. 3. The combination according to claim 1 wherein said main body member and said receiver member are resilient and are shaped for spring loaded engagement with said one temple and said frame front respectively. 4. The combination according to claim 1 including said outer end portion having a slot therein, said elongated resilient means being shaped to fit into said slot adjacent said open position. 5. The combination according to claim 1 wherein a second receiver member and a second main body member are similarly disposed on said frame front and on the other of said temples respectively, and second resilient means are supported on said second main body member for similar bearing contact with an outer end portion of said second receiver member. 6. The combination according to claim 5 wherein each of said end portions has a slot therein, and each of said resilient means are shaped to fit into the slot of the associated receiver end portion adjacent the open position of the associated temple. |
