Patent attributes
A method is provided for manufacturing a resilient hinge device for connecting the arms to a front frame of a mounting for spectacles. The device includes first and second hinge members which are pivotable about a hinge axis, and a resilient return between the hinge members. The method includes the steps of providing a box-like body open at a first and a second end thereof, axially opposed to one another, a slider member having a part formed with an eye or hinge pin, and at least one resilient member, and retaining same in a seat provided on the slider; and inserting the slider into the box-like body from the opening of the first end of the box-like body, with the part of the slider having the eye protruding outside the body through the opening provided in the second, opposed end of the body, the resilient member being located by the box-like body at the second end. The method also includes the steps of providing a closure member for the box-like body in the first end; firmly connecting the closure member to the 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 the resilient member; housing the box-like body in a respective blind cavity provided in the front frame of the mounting, with the closure member facing the bottom of the cavity; and firmly connecting the box-like body to the frame such that the 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 the hinge members of the device. Also provided is the resilient hinge device and spectacles including such device.
