Abstract

868,776. Spectacle frames. SAMCO-MAZZUCCHELLI CELLULOIDE S.p.A. June 3, 1959 [June 14, 1958; June 27, 1958(2); Jan. 3, 1959(2)], No. 18971/59. Class 97(1) Spectacle frames and temples are hingedly united by inserting through horizontal slots in the frame and temples flat-surfaced hinge elements with holes for the hinge pivot pin, said elements projecting beyond the frame and temples on their inward-facing side to a degree controlled by the abutment of a retaining portion of the hinge elements with a corresponding part of the frame or temple, and secured to each other and to the frame or temple by a pin inserted vertically through the aligned holes of both elements, said pin acting as the hinge pivot. In Fig. 1, the slot 2 is divided by a lateral bar 3 against which abuts the inner surface of the base of a C-shaped hinge element 6 the arms of which project behind the frame 1 receiving between them a second hinge element 7 projecting through a slot 5 in the temple 4, the said hinge element 7 having projections at its head lateral to its longitudinal axis for engaging by the temple. The two hinge elements 6 and 7 are provided with holes at their extremities aligned to receive a pivot pin 8 which also constrains the hinge elements in position. The Specification describes various embodiments of the invention which allow both hinge elements to have the shape of 7 in Fig. 1, and of which there may be one or two such elements in the frame or temple for each hinge joint. Alternatively, both hinge elements may be C-shaped as shown by 6 or with laterally projecting retaining portions similar to those of 7. The frame and temples may be recessed so that the hinge members when in position fit flush with the outer surfaces. In one particular embodiment, the slots are oblique as in Fig. 13 to allow the pivot pin 309 to fit closely in the angle between the frame and temple.
