Claims

[Claims for Utility Model Registration] (1) In an elastic hinge arm of an eyeglass frame comprising an arm rod 1 which is provided with an elastic device that expands when pulled and is connected to an eyeglass frame B by a hinge 2, the elastic device is An elastic hinge arm of an eyeglass frame, characterized in that it consists of the following elements: An outer case 3 consisting of a metal piece having a shaft hole 3' for housing a mechanism providing elastic extensibility and a horizontal hole 3'' penetrating the shaft hole; an elongated rod protruding from a part of the hinge head 4; a hinge element 4 with an externally threaded end 4'' and dimensions such that it can be inserted into the shaft hole 3' of said outer case; a helical spring 5; a bushing 7 having a spring receiving seat on the hinge side for expanding and contracting the spring, into which the spring 5 can be fitted and at the same time inserted into the shaft hole 3' of the outer case;
Horizontal hole 3″ of the outer case 3 for the bushing 7
a fixing screw device screwed onto the male threaded end 4'' of the spring 5 fitted into the rod 4' of the hinge element; (2) a fixing screw device screwed into the bushing; Utility model registration claim 1, characterized in that a slot 7'' is provided for accommodating a part of the head 4 so as to be able to slide in the axial direction, thereby preventing rotation or rocking. elastic hinge arms of eyeglass frames.
