Definitions

• the field of the invention is that of spectacle frames.
• An eyeglass frame generally comprises a front face extended by two lateral tenons, as well as two articulated branches on the tenons around the hinge axes of two hinges.
• Each hinge comprises a front face member, integral with a lateral tenon, and a branch member, integral with the corresponding branch, these two elements being articulated on the hinge axis of said hinge.
• each branch can, by rotation about the hinge axis of the corresponding hinge, successively take two positions relative to the lateral pin which it is associated.
• said opening the branch extends the post and extends substantially at right angles to the general plane of the front face, which allows the mount to be worn.
• said closure the branch is substantially parallel to the front face and pressed against it, which reduces the volume of the spectacle frame.
• each hinge can be telescopic.
• Such "over-opening" of the branch ensures greater comfort when the mount is pavement on the nose and, moreover, avoids any risk of breakage or deformation of the frame and branches.
• such a telescopic hinge comprises a slide mounted on the one hand on the hinge axis of the hinge, and on the other hand in a sleeve integral with the corresponding branch (or a core). on which the branch is formed).
• This slide is able to slide in the sheath against and under the action of a spring, generally compression, which also extends in said sheath. This spring thus allows to press the branch against the face, while allowing precisely an over-opening of the hinge.

• the dismantling of the hinge can be easily operated by the removal of the intermediate fixing means, the latter being for example first removed from the first fixing means (of the element front panel), then the second (of the branch element).
• the intermediate fixing means limits the bias of the spring during the separation between the branch member and the front face branch member, which ensures easy disassembly (or reassembly) of the hinge.
• the intermediate fixing means because of the design flexibility afforded by the intermediate fixing means, it is possible to provide a first fixing means whose shape is not necessarily a hook or an eyelet, which therefore makes it possible to limit the congestion - as well as to promote greater discretion - the lateral tenon to which the hinge is intended to be secured.
• hinge usually used to designate devices connecting a branch to the front of a spectacle frame. It is clear that, if ever, it should be associated with this term any limitation, it is the term articulation that should be substituted for the term hinge, for a perfect understanding of the invention.
