Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to eyeglass frames.

[0002]

[Prior art]

 FIG. 3 is a plan view showing a part of a conventional spectacle frame. 1 is a rim of a front frame on which a lens is mounted, 2 is a lens for fixing the mounted lens to the rim 1 by using machine screws 3. The tightening portion 4 is a substantially L-shaped tip connecting the tightening portion 2 and one hinge 5a, and 6 is the other hinge 5b rotatably coupled to the one hinge 5a at one end. And a plastic ear piece 7 is fixed to the other end of the temple.

In the above-mentioned conventional spectacle frame, various adjustments are made to match the face of the person who uses it.

For example, in order to fit the side length of the face and the spectacle frame, it is necessary to adjust the length of the temple 6 parts, but the hinge 5b and the earpiece 7 are fixed to the ends. Since it is difficult to cut the temple 6 itself and adjust the length, as shown by the chain double-dashed line in FIG. The length of the temple 6 part was adjusted by changing the state.

Further, although not shown, a plastic connecting member is fixed to the hinge member 5 portion including the hinges 5a and 5b, and a temple adjusted to an appropriate length is fitted to the connecting member. There are some that I did.

[0006]

[Problems to be solved by the device]

 The length adjustment of the temple portion in the conventional eyeglass frame cannot be significantly adjusted by the method of bending the earpiece, and in the method of using the connecting member, the connecting member is made of plastic. However, there was a problem in strength.

An object of the present invention is to provide a spectacle frame in which the length of the temple portion can be easily and easily adjusted, and which has excellent strength and durability.

[0008]

[Means for Solving the Problems]

 To achieve the above object, the eyeglass frame of the present invention is an eyeglass frame in which a front frame and a temple are connected via a hinge member, and the eyeglass frame is provided on the hinge member and has a slit formed on a side portion. And a metal tubular member that is screwed onto the outer periphery of the tubular member with the end portion of the temple inserted in the tubular member and is fastened to the hinge member by tightening the end portion of the temple. And a fastening member.

Further, the cylindrical member and the fastening member are formed of titanium or a titanium alloy.

Further, the fastening member is a tubular nut member having a tapered surface formed on the inner surface.

Further, the present invention is characterized in that a holding member for holding temples having various sectional shapes can be attached to the tubular member.

[0012]

[Action]

 In the spectacle frame having the above structure, a temple cut to an appropriate length is inserted into the tubular member, and in that state, the fastening member that is loosely screwed into the outer periphery of the tubular member is further screwed to slit the tubular member. Deform within the range of and fix the temple to the hinge member by tightening the temple through the tubular member.

If the tubular member and the fastening member are made of a metal material, the mechanical strength is excellent, and if they are made of a titanium material, the weight can be reduced.

Further, by making the fastening member a tapered tubular nut member, the tightening force can be increased due to the presence of the taper.

Further, by using a holding member that can hold temples having various cross-sectional shapes, the length can be adjusted even if the temples have various shapes.

[0016]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. The same members as those described in FIG. 3 are designated by the same reference numerals, and detailed description thereof will be omitted.

FIG. 1 is a plan view in which a part of a first embodiment of the present invention is shown, and 10 is fixed to or integrally formed with a hinge 5b on the temple 6 side of a hinge member 5 and has a side portion. A titanium tubular member 13 having a slit 11 and an external thread portion 12 is a female thread portion 14 that is screwed into the external thread portion 12 of the tubular member 10, and a taper surface 15 that presses the outside of the tubular member 10. And are cylindrical titanium nut members formed on the inner surface.

In the first embodiment having the above-described structure, the temple 6 having a circular cross section cut into an appropriate length is inserted into the tubular member 10, and in that state, the fastening member is loosely screwed into the outer periphery of the tubular member 10. The nut member 13 is further screwed in to deform the tubular member 10 within the deformable range of the slit 11 portion, and the temple 6 is tightened via the tubular member 10 and fixed to the hinge member 5.

FIG. 2 is an exploded view showing a main part of a second embodiment of the present invention. In the second embodiment, the shape of the cross section of the temple 6 is not limited to a circle, but is rectangular or polygonal. A cylindrical holding member 22 having a slot 20 on the side and a supporting hole 21 conforming to the cross-sectional shape of the temple 6 to be used is provided inside the cylindrical member 10 so that it can be dealt with. It is something to insert.

In the second embodiment having the above-mentioned structure, the temple 6 is appropriately cut while the holding member 22 is inserted into the tubular member 10, and then the temple 6 is inserted into the support hole 21. The temple 6 is fixed by screwing 13 in.

A fine unevenness 23 is formed on the outer side of the temple 6 so that the inner wall of the support hole 21 and the outer side of the temple 6 are securely engaged with each other. The unevenness may be formed on the inner wall of the support hole 21.

[0022]

[Effect of device]

 As described above, according to the spectacle frame of the present invention, according to the invention of claim 1, the temple whose length is adjusted by cutting it to an appropriate length is simply provided by the fastening member via the tubular member. Further, it can be easily fixed to the hinge member, and since the tubular member and the fastening member are made of metal, the mechanical strength is excellent and the durability can be improved.

According to the second aspect of the present invention, the weight can be reduced by using the titanium material as the metal material.

According to the third aspect of the present invention, the fastening member is a tubular nut member having a taper, whereby the tightening force can be increased due to the presence of the taper, and the temple can be firmly fixed. .

According to the fourth aspect of the present invention, the length of the temples having various shapes can be easily adjusted by using the holding member capable of holding the temples having various sectional shapes.
