Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to an improvement of an eyeglass frame which includes an armor at an outer end of a lens frame surrounding a lens, a temple is joined to the armor via a hinge, and spring means is incorporated at the joint.

[Prior art]

 When the spectacles are attached or detached, the force of trying to expand the temples of the spectacle frame to the outside excessively is applied, and the armor and / or the temple portion may be deformed to impair the comfort of wearing the spectacle frame. In order to prevent such armor and temple deformation, a spring hinge that incorporates a coil spring in the hinge that joins the armor and the temple is used to absorb the force that tries to expand the temple outward, A spectacle frame that allows the temple to be pivotally displaced outward is known.

[Problems to be solved by the device]

 However, in the above-mentioned conventional eyeglass frame using the spring hinge, not only is the coil spring assembly structure complicated, the number of parts is large, and the assembly of each part is complicated, it is difficult to replace the temples. There was a problem that the armor and the temple were enlarged and the spectacle frame was spoiled. The present invention has been made to solve the above problems, and has a small number of parts, a simple structure, easy assembly, a small size and a light weight, and fewer frame design restrictions. The purpose is to provide a spectacle frame.

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a spectacle frame comprising a pair of lenses or an outer edge of a lens frame, and a temple rotatably joined to the armor via a hinge. A spring accommodating part is provided at the rear part of the armor, and a part of the spring member inserted in the spring accommodating part is projected outside the rear end of the spring accommodating part, while the spring protruding part of the spring member is provided outside the tip end of the temple. The engaging claw portion is provided, the temple can be pivotally displaced to the outside, and the temple is biased inward by the spring protrusion. It is desirable that the spring member is formed by bending a metal plate or is formed in a block with an elastic material such as rubber. Alternatively, a flat leaf spring may be used, one end of which is fixed to the front portion of the armor and the other end of which is a free end.

[Action]

 With the above structure, when a force for expanding the temple is applied when the spectacle frame is attached or detached, the external force is absorbed by the spring member accommodated in the spring accommodating portion, and the temple is rotated outward. Since the temple is biased inward by the spring protrusion while being displaced, the temple and the armor are not deformed, and good comfort is maintained.

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. The spectacle frame 1 includes a lens frame 3 surrounding a pair of lenses 2 and 2, a pair of armours 4 and 4 provided at the outer end of the lens frame 3, and hinge pins 9 and 9 to each armor 4 and 4. It is composed of a pair of temples 5 and 5 which are joined together so that they can rotate inward and outward. Reference numerals 6 and 6 are nose pads, 7 is a reinforcing bridge, and 8 and 8 are front cells for holding the glasses against the ears. As shown in FIGS. 2 and 3, each armor 4 has a spring housing portion 10 having a rectangular cross-section and extending rearward, and a pair of end plates 11 and 11 extending from both upper and lower sides thereof have hinge holes 12 and 12, respectively. Is provided. The spring member 13 loaded in the spring accommodating portion 10 is a leaf spring formed by bending a metal plate having elasticity into a U-shape as shown in FIG. 3, and an outer end portion of the spring member 13 is formed. Project from the opening of the spring accommodating portion 10 to form a spring protrusion 13 a. As shown in FIG. 4, the spring member 13 has a middle portion bent into a U-shape, one end of which is press-fitted and fixed to the inside of the spring accommodating portion 10 and the other end of which is outside the rear end of the spring accommodating portion 10. The spring protrusion 13a may be formed by extending along the opening and protruding from the opening. When the spring member 13 is formed of a leaf spring having large elasticity, one end of a flat leaf spring is fixed inside the spring accommodating portion 10 and the other end is set as a free end, as shown in FIG. The free end may extend along the outer side of the rear end of the spring accommodating portion 10 to form a spring protruding portion 13a protruding from the opening of the spring accommodating portion. Further, as shown in FIG. 6, the spring member 13 may be made of an elastic material such as rubber in a lump shape, and the rear end portion may protrude from the opening of the spring accommodating portion 10 to form a spring protruding portion 13a. At the tip of each temple 5, there is a thick connecting portion 15 which is inserted between the bifurcated end plates 11 of the armor 4 and closes the opening of the spring accommodating portion 10. A claw portion 16 that engages with the spring protrusion 13a of the spring member 13 is provided at the outer tip. Further, the connecting portion 15 is provided with a hinge hole 17 that matches the hinge hole 12. In the above embodiment, the eyeglass frame 1 in which the armor 4 is provided on the outer end of the lens frame 3 has been described, but the present invention can also be applied to an eyeglass frame in which the armor 4 is directly attached to the lens 2. Is.

[Effect of device]

 As described above, according to the present invention, by simply inserting a spring member having a simple structure into the spring accommodating portion provided on the armor, an external force that excessively expands the temples of the spectacle frame to the outside acts. Can also absorb this and prevent deformation of the armor and / or temple parts. Moreover, the number of parts is small, cost can be reduced, the size and weight can be reduced, and there are few restrictions on design. It is easy to assemble and can be repaired at low cost.
