Abstract

<P>PROBLEM TO BE SOLVED: To obtain more designing flexibility and functional flexibility of the frame of spectacles in the easiness of the exchange of a temple, and to realize the improvement of housing performance and the length adjustment of the temple for fitting without spoiling a function and design. <P>SOLUTION: In the frame of the spectacles, metal having high flexibility is used for an end-piece part, and a screw thread is formed toward the edge part in the major axis direction of the end-piece, and a screw hole for locking a screw is cut at the specified position of the temple, and the end-piece and the temple are screwed and fit through a lock nut. Thus, the feeling of wearing is improved, and the exchange, the housing and the length adjustment of the temple are easily performed. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a joint structure in which temples can be easily detached and replaced.

Conventionally, a spectacle frame has been recognized and sold as a complete piece of spectacles. There is no other way for the user to use different functions, colors, shapes, and materials depending on the usage situation, other than by switching to other eyeglass frames.

However, there is also a connecting mechanism capable of exchanging and removing the temple (see, for example, Patent Document 1). However, this technique has a disadvantage that the structure of the connecting portion is complicated, fitting accuracy is required, and the design is restricted.

JP 2001-117052 (Pages 8-15, Fig. 1)

For the purpose of improving comfort, eyeglass frames that do not have a hinge or equivalent opening and closing mechanism use a highly flexible metal or resin for the temple material, from the armor part to the ear hook part, Or because it is integrally molded from the ear hook part to the opposite ear hook part, the storage property is inferior to that of conventional eyeglass frames, and the user himself / herself for functional reasons, decorative reasons, damage etc. It was not easy to change temples according to TPO.

Further, in a conventional frame having a hinge or an equivalent opening / closing mechanism, it is not easy to use a tool such as removing a hinge screw when replacing the temple.

The shape of the human face and skull are slightly different in size, so the temple length at the store is adjusted by brazing the hinge at the mouth of the temple. Although it is supported by bending and stretching, there is a limit to it naturally, and it also affects the comfort of wearing.

In order to solve the above problems, first of all, a spectacle frame having metal armor portions at both ends, the tip of the metal armor portion has a shape with a thread in the axial direction, Employs a temple joint structure in which a screw hole is cut in the axial direction at the tip opposite to the ear hook, and the temple is screwed to the armor portion via a lock nut. By using a metal with high flexibility in the armor part, it is possible to improve the wearing comfort and replace the temple even if it is in a frame that does not have a hinge or equivalent opening and closing mechanism, Convenience of storage also occurred.

An eyeglass frame having metal temples at both ends, wherein the metal temple is composed of a first temple and a second temple, and the first temple has an opening and closing mechanism equivalent to an armor part and a hinge or the like at the tip part. The tip of the first temple opposite the armor portion connecting portion is threaded in the axial direction, and the second temple is at the tip opposite to the ear hook portion. By adopting a temple joint structure characterized by having a shape with a screw hole cut in the axial direction and screwing the second temple to the first temple via a lock nut, The temples can be easily removed and replaced.

Further, in order to adjust the length of the temple, if the fine adjustment is made, the lock nut is positioned at the position of the lock nut, and if it is more than that, the screw hole for screwing the temple is deeply cut. By cutting the tip at a store, it was possible to easily adjust without damaging the shape function of the ear hook.

Conventional eyeglass frames have been recognized and sold as a complete eyeglass frame, but by adopting the joint structure of the present invention, temples are produced and sold separately by function, color, shape, and material. You can choose the temple at your own will. With a single spectacle frame, it has become easy to replace the temple adapted to various situations such as use during exercise with the user's own hand as needed.

In the conventional spectacle frame, the temple length has been adjusted by bending and stretching the ear hook at the store. However, it has its own limits and has an impact on comfort. In the present invention, adjustment is possible without impairing the shape of the ear hook.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is an exploded perspective view of an essential part of the first embodiment. A screw thread is set up at the tip 5 of the armor portion 1 in the axial direction, a lock nut 3 is passed through the screw from the rear, and an ear of the temple 4a. A screw hole is cut in the axial direction at the tip 8 on the opposite side of the hook 7, and is screwed to the armor and fixed with the lock nut 3.

FIG. 2 is an exploded perspective view of an essential part of another embodiment of the present invention, in which a screw thread is set up in the axial direction on the distal end portion 5 of the first temple 2 opposite to the armor portion connecting portion 6. Then, the lock nut 3 is passed through the screw from the rear, and a screw hole is cut in the axial direction in the tip 8 on the opposite side of the ear hook 7 of the second temple 4 and screwed to the first temple for locking. The structure is fixed with a nut 3.

Needless to say, the connecting portion 6 of the armor portion 1 and the first temple 2 is not limited to the embodiment shown in FIG.

The principal part disassembled perspective view of the Example of this invention Exploded perspective view of the main part of another embodiment

Claims (3)

An eyeglass frame having metal armor portions at both ends, the tip of the metal armor portion having a threaded shape in the axial direction, and the temple in the axial direction at the tip opposite to the ear hooking portion The joint of the temple is characterized in that it has a shape in which a screw hole is cut and a method of screwing the temple to the armor portion via a lock nut makes it easy to remove and replace the temple. Construction. An eyeglass frame having metal temples at both ends, wherein the metal temple is composed of a first temple and a second temple, and the first temple has an opening and closing mechanism equivalent to an armor part and a hinge or the like at the tip part. The tip of the first temple opposite the armor portion connecting portion is threaded in the axial direction, and the second temple is at the tip opposite to the ear hook portion. By adopting a method in which a screw hole is cut in the axial direction and the second temple is screwed to the first temple via a lock nut, the removal and replacement of the temple is facilitated. Characteristic temple joint structure. The depth of the screw hole is adjusted so that the length of the temple having the screw hole for screwing can be adjusted by cutting the tip of the temple opposite to the ear hooking portion. The temple joint structure according to claim 1, wherein the temple joint structure is cut deeper than the length of the temple.
