Abstract:
1. A method for manufacturing a resilient hinge device for connecting arms to a front frame of a mounting for spectacles, the device including a first and a second hinge member which are pivotable about a hinge axis (X), and resilient return means between said hinge members, the method comprising the steps of: providing a box-like body open at a first and a second end thereof, axially opposed to one another, providing a slider member having a part formed with an eye or hinge pin, providing at least one resilient member and retaining same in a seat provided on the slider, inserting the slider into the box-like body from the opening of said first end of the box-like body, with the part of the slider having the eye protruding outside said body through the opening provided in the second, opposed end of said body, said resilient member being located by the box-like body at the second end, providing a closure member for the box-like body in said first end, and firmly connecting said closure member to said body, such that the slider is retained so as to be slidably guided in the box-like body and is also displaceable relative to the box-like body counter to the resilient action exerted by said resilient member, housing said box-like body in a respective blind cavity provided in the front frame of the mounting, with said closure member facing the bottom of the cavity, firmly connecting the box-like body to the frame such that said body is rigidly fixed in position, at least partially embedded in the front frame of the mounting, the part of the slider having the eye constituting one of said hinge members of the device.
