Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an eyeglass temple, and more particularly, to a biasing force applied to a temple in a folding direction with an extremely simple structure. This temple relates to a spring-type eyeglass temple that realizes comfortable wearing by fitting a user's temporal region with an appropriate pressure. 2. Description of the Related Art When trying to attach and detach spectacles, the free end side of the temple tends to be inevitably expanded outward, which causes a large portion of the temple at the base end. The force was applied, and the eyeglass frame was likely to be damaged or deformed. Conventionally, as a proposal for eliminating such adverse effects, one hinge piece part of a hinge for hinge-connecting the front frame and the temple can be elastically advanced and retracted by a coil spring provided at the base end of the temple. There is a so-called "spring hinge". [0003] However, since the structure of the spring hinge is generally complicated and the components thereof are minute, the components constituting the temple hinge are frequently worn due to frequent temple opening and closing operations.
Immediately, this outward spreading operation becomes sweet, or conversely, the sweat or sebum of the wearer permeates into the hinge mechanism and corrodes the spring, etc., and it is difficult for the temple to return to its original state while expanding outward. Sometimes it was. When such a failure occurs, it is necessary to replace the spring hinge. The conventional spring hinge is constructed together with the assembly of the hinge part, and the structure is complicated as described above. Therefore, the replacement work is very troublesome and requires skill, and furthermore, there is a complaint that the cost is inevitably increased due to the small number and large number of the components. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks.
A spring-type eyeglass temple that can apply a biasing force in the folding direction to the temple with an extremely simple configuration, and this temple fits the user's temporal region with appropriate pressure to realize comfortable wearing. Is to do. Means adopted by the present inventor to solve the above problems will be described below with reference to the accompanying drawings. That is, the present invention relates to an eyeglass temple hinged to a take-out end of an end piece E provided on each of the left and right sides of the eyeglass front part F by a pivot S, and connected to the end piece E. Power piece 10 is formed on the base end side ,
A relay member 1 capable of expanding and folding the eyeglass temple ; a cover body 2 covering the upper and lower surfaces of the relay member 1 and having a vertical bearing 21 provided at a required position;
And a repulsion member disposed inside the base end side of the relay member 1 and formed by bending a metal wire.
And the winding part 41 is inserted through the longitudinal axis 3 and supported.
The spring 4 torsion made bifurcated metal; a longitudinal member having a base end side by the longitudinal axis 3 Ru is pivoted, at typically proximal to the stop piece 11 that is the draw formed into the relay member 1 while unit 51 is Ru is衝止, the pivot S proximal end 51 is the metal of the longitudinal axis 3 as a fulcrum when obtained by extender pivoted outward relative to the spectacle front F of the free end side as a fulcrum Bifurcated torsion spring 4
And an ear-hyun member 5 which is resiliently repelled by compressing and biasing the end in the closing direction . [0010] Embodiments of the present invention will be described below in more detail with reference to the accompanying drawings. An embodiment of the present invention will be described with reference to FIGS. In FIG. 1, what is indicated by reference numeral F is a pair of rims R, R, which is a pair of rims R and R symmetrically connected to each other by a bridge B. A relay member indicated by reference numeral 1 is disposed at the take-out end of E. A piece 10 formed on the proximal end side of the relay member 1 is pivotally connected to an end piece
Of the eyeglass temple
And folding operation is possible. Reference numeral 2 designates a cover body for covering the upper and lower surfaces of the relay member 1. The cover body 2 is provided with a vertical bearing 21 at a required position. Also, reference numeral 3
Is indicated by the vertical axis, and the vertical axis 3 employs small screws. What is designated by reference numeral 4 is to bend a metal wire.
And the winding portion 41 is inserted through the longitudinal axis 3.
It is a forked metal torsion spring supported by
What is designated by reference numeral 5 is an ear-hyun member, and the ear-hyun member 5 forms an ear-hook portion. First, a vertical bearing 21 is provided at a required portion of the cover 2 of the relay member 1. The vertical bearing 21 in the present embodiment is formed with a screw thread so that a small screw which is the vertical axis 3 can be screwed. Then, the vertical axis 3 is screwed into the vertical bearing 21 attached to the relay member 1 so as to be capable of bearing, and the base end side of the ear-hyun member 5 is supported so that the ear-hyun member 5 can be opened and closed freely. Hinges pivot. [0015] In this case, since the temple is fully proximal end 51 to the stop piece 11 that is the draw formed into the relay member 1 in normal time when not expanded is衝止, metallic torsion spring 4 The ear-hyun member 5 can be stopped even if it is interposed inside the base end side of the relay member 1 with a certain elastic repulsive force. As shown in FIG. 3, if the free end side of the ear-hymn member 5 is to be spread outward with respect to the spectacle front F with the pivot S as a fulcrum, the vertical axis 3 is used as a fulcrum.
Of the metal torsion spring 4 closes the forked ends of the torsion spring 4
Compression in the same direction . [0017] [0018] Metal torsion spring 4 is bent forming a metal wire having a spring property such as β titanium, since the vertical axis 3 is supported by inserting the winding unit 41, When the ear-hyun member 5 is expanded, both ends are compressed and elastically deformed, and the elastic repulsive force can urge the ear-hyun member 5 in the folding direction. The present invention is generally configured as described above.
The present invention is by no means limited to the illustrated embodiment, and various modifications are possible within the scope of the claims. For example, the vertical bearing 21 of the cover body 2 can be formed without threading. The vertical axis 3 may be formed so as to be fitted, and it is needless to say that the present invention can be applied to half-rim spectacles and rimless spectacles, and any of them belongs to the technical scope of the present invention. As described above with reference to the embodiments, the present invention utilizes only the deformation of the repulsion member, so that its structure is simple and can be made compact. Improvements and manufacturing costs can also be reduced. When wearing spectacles, the temple is fitted to the side of the head. If an object is hit while the spectacles are being worn, the temple is elastically expanded to cushion the shock, It is also possible to prevent side damage.
