Problems solved by technology

[0008] In the frame of the above-mentioned type, because of the presence of the spring, the size and weight of the temple hinge are quite large.
Also, for this reason, the temples are rather thick at the hinges
All of this contributes to the frame being heavy in the front area, which is detrimental to comfort, especially on the user's nose, which becomes embossed by the bridge that connects the two front lenses that support the lenses. part

Embodiment Construction

[0031] refer to figure 1 , a conventional spectacle frame of the prior art comprises a front 1 for receiving lenses (optical lenses) and a right temple 2 and a left temple 3, in the example shown, said right temple 2 resting against the front 1 The rear is folded in a closed position, while said left temple 3 is in an open position substantially perpendicular to the entire plane of the front 1 . Extending laterally substantially at right angles to the front 1 are two lateral front lugs 4, 5 to which the temples 2, 3 are hinged by means of two hinges 6, 7, the two hinges 6, 7 are referred to here as telescoping hinges.

[0032] The telescoping hinge (for example, the left hinge 7) comprises a front element 8 rigidly connected to the front lug 5 and a temple element 9 rigidly connected to the temple 3, here more precisely , connected to the web 15 of said temple on which the web 15 is formed. The two hinge elements are hinged on a hinge arbor 11 rigidly connected to the front...

Abstract

The invention relates to a spectacle frame having two temples articulated by two telescopic hinges, each temple having a front element and a temple element, the temple element having a slide (123) hinged to the front element and Mounted to slide within the sheath (125) under and against the action of the spring (126). The slider (123) extends as far as the free end of the temple (15) providing said sheath (125). A sleeve (130) mounted on a slider (123) slides within the end of the temple, within which the spring (126) also extends. The temples are formed in two parts, namely a main part (115) and an end forming an end piece (117) in which a spring (126) is deployed. The end piece (117) is mounted to rotate relative to the main temple portion (115) to adjust the tension in the spring (126).

Description

technical field [0001] The field of the invention is that of spectacle frames. Background technique [0002] The spectacle frame comprises a front face and two temples mounted such that each leg is hinged on a lateral lug on the front face by means of a hinge. [0003] In the open position, the temples are extended substantially perpendicular to the entire plane of the front. [0004] Telescoping hinges allow the arms to open beyond this right angle. By virtue of this "over-opening", said hinge provides greater comfort when the frame rests on the nose and avoids the risk of breaking or deforming the frame and temples. [0005] Telescoping eyeglass frame hinges typically include springs that press the temples against the head but specifically allow over-opening. [0006] Telescoping hinges generally consist of two elements assembled on a hinged mandrel and rigidly connected respectively to the front lug (front element) and to the temple (arm element), in particular to the ...
