Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temple joint structure of a spectacle frame configured without using a hinge.

[0002]

[Prior art]

 The spectacle frame has a vine that can be folded. Conventionally, hinges have been used as folding means for the vines, and the hinges are fixed to the armorings brazed on both sides of the front frame, and the vines are connected via the hinges. Since hinges are relatively small, it is difficult to connect long cranes, and the hinges often wear and rattle.

Of course, the means for connecting the vine so that it can be folded is not necessarily limited to a hinge, but in general, it has an axis serving as a bending center for folding the vine. In the case of a hinge, it has a shaft screw that connects both hinge pieces, and it is the center of bending of the vine, but the rattling of the vine is often due to the looseness of this shaft screw. . Especially in recent years, eyeglass frames have become extremely slim in consideration of weight reduction and design, and therefore the hinges that connect the vines have become even smaller, which promotes rattling of the vines.

If the vine is rattled in this way, it is necessary to re-tighten the shaft screw, but it is easy for an ordinary person to tighten the small shaft screw to eliminate the rattling of the vine. Not only that, you have to ask an expert. On the other hand, the use of small hinges hinders the manufacturing and assembly work of the hinges, and the brazed hinges have a small brazing area, which makes them easy to come off.

[Problems to be solved by the present invention]

 As described above, the temple joint structure of the eyeglass frame has the above problems. The problem to be solved by the present invention is this problem, and a sliding joint structure is provided in which the sliding area due to bending of the vine is increased and the vine does not rattle. Also, if there is looseness, use a crane joint structure that can be easily retightened and re-fixed.

[0006]

[Means for Solving the Problems]

 The crane joint structure of the present invention has a structure in which the temple end is inserted into a screw hole formed in the end piece and screwed. The threaded hole of the armor is a stepped hole that forms a large seat on the upper side. A nut is inserted into this large diameter seat and screwed into the shaft screw of the crane. A thin sliding plate and a washer are set on the bottom of the seat and tightened with nuts. On the other hand, the nuts are located on the lower surface of the endpiece and screwed into the shaft screws. That is, the shaft screw of the crane is tightened by the upper and lower nuts and is stably connected to the armature without rattling.

Here, the nut used on the upper side of the end piece may protrude from the seat, and a decoration may be attached to the upper end if necessary. Further, the end piece has a stopper formed at the tip from the screw hole, and the temple end portion is curved to form a screw portion. When the temple is opened, the stopper comes into contact with the stopper and the opening degree is regulated. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 1 (a) and 1 (b) are embodiments showing eyeglasses equipped with the temple joint structure of the present invention. As is apparent from the figure, this spectacle does not have a rim, both lenses 1 and 1 are connected by a connecting member 2, and the end pieces 3 and 3 are attached to the outside of the lenses. Further, the temple 4 is connected to the end piece 3 so that it can be folded at the joint portion 5, and the nose pads 6 are provided inside the lens and below the connecting member 2. Of course, the spectacle frame targeted by the present invention is not limited to the rimless spectacles described above, and may be a spectacle frame having rims on the left and right.

FIG. 2 is a specific example showing the temple joint structure of the present invention. A screw 8 is curved at the end of the temple 4, and the screw 8 is connected through a screw hole 7 formed in the end piece 3. The screw hole 7 has a size into which the screw 8 can be fitted. A large seat 9 is formed on the upper side of the screw hole 7, and a lower part of the upper nut 10 is fitted into the seat 9. Then, another lower nut 11 is screwed onto the bottom of the screw 8, a thin sliding plate 13 is interposed between the lower nut 11 and the bottom surface 12 of the end piece, and a sliding plate 13 and a washer are also provided on the bottom surface of the seat 9. The upper nut 10 is screwed with 14 interposed.

Therefore, if the upper nut 10 is tightened with the lower nut 11 fixed to the screw bottom, the screw 8 is pivotally supported in the screw hole 7 without rattling. This screw 8 has a screw diameter corresponding to the thickness of the temple 4, and is much thicker than the shaft screw of the hinge, and the upper and lower nuts 10 and 11 can be made larger, which results in stable tightening. To do. Although the screw 8 rotates when the temple 4 is folded, the upper and lower sliding plates 13 and 13 slide smoothly to prevent the upper and lower nuts 10 and 11 from loosening.

In the present invention, the upper nut 10 can function as a decorative member, and the decoration 15 is attached to the upper end of the upper nut. Further, as shown in FIG. 1 (b), the vine 4 has a curved end portion to form a screw 8. However, a stopper 16 is formed at the tip of the end piece 3, and the stopper 16 has a vine end portion. The degree of opening can be regulated.

FIG. 3 shows another embodiment of the present invention in which the shape of the temple end is different. That is, the stopper 16 formed at the tip of the end has a bent shape so as to hit the vine. Of course, in this embodiment, the stopper 16 formed on the end piece 3 extends linearly, but it may be formed in a bent shape. In this case, the shape of the temple end portion is different. As described above, the crane joint structure of the present invention is one in which the screw provided at the end of the temple is inserted into the screw hole formed at the end of the end piece and tightened with the upper and lower nuts, and the following effects are obtained. You can

[0013]

[Effect of device]

 Unlike the conventional hinge joint, the temple joint structure of the present invention can realize stable folding operation forever. In other words, it is a structure in which a screw of about the same size as the crane is inserted into the screw hole formed in the end piece, and the nuts are tightened at the top and bottom of the screw. Then, if the nut becomes loose and the vine rattles, it is possible to eliminate the rattling of the vine by simply tightening the upper nut. Moreover, since the upper nut is relatively large, a decoration can be attached to the upper end, and it will function as a decorative member for the spectacle frame.
