[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle temple connecting structure mainly used for connecting a lens and temples of rimless spectacles, and more specifically, to troublesome parts other than screws on the front and side surfaces of the lens. The present invention relates to a structure for connecting spectacle temples in rimless spectacles with good productivity, in which a lens and a temple can be simply and reliably connected without attaching a hinge, and a conventional hinge attached to the temple is unnecessary.

[0002]

2. Description of the Related Art Conventionally, as a structure for connecting spectacle temples in such rimless spectacles, for example, an actual flat screen 2-582 is used.
The one disclosed in No. 16 is well known as a conventional example. As shown in FIG. 12, the connecting structure in this conventional example has connecting holes L ₁ formed at two upper and lower positions in the vicinity of the side circumference of the lens L, and each branch end in which the front part of the temple T is branched vertically. Connection holes 7a are formed near 7 and 7, and bolts 9 are attached to the upper and lower parts of the back surface of a plate 8 having a decorative surface, and the rear portions of the bolts 9 are connected to the temple T and the lens L, respectively. hole 7a, through the L ₁ is protruded to the rear of the lens L, had a structure formed by fastening the nut 11 via respective washers 10 in the projecting portion (real Hei 2
-58216).

Further, as shown in FIG. 13, a column 12 made of a synthetic resin material is adhered to a lens L made of glass or a synthetic resin material, and a component 13a of a hinge 13 and a fastening component are embedded in the column 12. There is also a method of fixing the spectacle temple (Japanese Patent Laid-Open No. 57-53724).

[0004]

However, among the above-mentioned conventional examples, in the connection structure of the spectacle temple in the rimless spectacles disclosed in the former Japanese Utility Model Laid-Open No. 2-58216, the front surface of the lens L is used. Since the branch ends 7 and 7 and the two plates 8 and 8 of the temple T are exposed on the side surface and the side surface, it is troublesome in appearance and, in addition to the hinge 13 being attached to the temple T, the temple T itself. However, the configuration is complicated, assembly takes time and labor, and the productivity is poor, and the cost is high.

In the latter method for fixing the spectacle temple disclosed in Japanese Patent Laid-Open No. 57-53724, since the column 12 made of synthetic resin is adhered to the lens L, the column 12 is It is easy to come off due to external shock, etc.
The pillar 12 and the hinge component 13a are inevitably connected to each other, and when the temple T is opened, the tip of the temple T on the connecting portion side abuts on the inside of the lens L, which damages the lens L. There was such a problem.

The present invention has been made in view of the above problems, and the lens and the temple can be easily connected to each other without attaching any troublesome parts other than the screw on the front surface or the side surface of the lens, and the temple can be connected to the conventional one. An object of the present invention is to provide a spectacle temple connection structure for rimless spectacles which does not require a hinge and has good productivity.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned conventional problems and to achieve the intended purpose, the constitution which is the gist of the present invention is to attach / detach to / from a connecting hole formed at a predetermined position of a lens. In an eyeglass temple connection structure for rimless eyeglasses that is freely fitted and supported to rotatably hold the base end side of the temple, an insert portion formed in a shape that is removable and non-rotatable with respect to the connection hole. An edge characterized in that at least a front surface side is formed larger than a rear end of the insert portion, and the temple is rotatably held via a connecting member having a joint portion abutting against the lens. It exists in the connection structure of the spectacle temples in the spectacles.

Further, it is preferable that the insert portion is formed into a square tube which is fitted in a non-rotatable state in a connecting hole formed in a square shape.

Further, it is preferable that the joint portion is provided with a mounting hole for supporting the base end side of the temple and a stopper for restricting rotation of the temple.

The temple may be rotatably supported by the connecting member by bending the base end side into a desired shape so that the base end side comes into contact with the fixed portion of the connecting member only at a predetermined position.

[0011]

According to the structure for connecting the spectacle temples in the rimless glasses of the present invention configured as described above, the connecting member has at least an insert portion formed in a shape that is removable from the connecting hole and cannot rotate. Since the front side is formed to be larger than the rear end of the insert section and has the joint section that comes into contact with the lens, it is possible to attach / detach and become unrotatable by simply inserting the insert section into the connecting hole of the lens. Since it is fixed and the front surface of the joint portion abuts on the lens, easy slip-out and rattling are prevented.

Further, by forming the insert portion into a square tube which is fitted into the squarely formed connecting hole in a non-rotatable manner, there is no pad or seal member in the connecting hole. It will be possible to firmly connect.

Further, since the joint portion is provided with a mounting hole for supporting the base end side of the temple and a stopper for restricting the rotation of the temple, the temple bent in a predetermined direction is provided. By simply attaching the base end side to the attachment hole, the base end side of the temple comes into contact with the stopper,
The temple will be prevented from opening.

Further, by inserting the bush into the mounting hole, the hardness when the temple is rotated (opened / closed) is determined by the frictional force between the mounting hole and the bush and the frictional force between the bush and the temple. It can be set freely, and by preparing several types of bushes with different thicknesses and hole shapes in advance, temples with different diameters can be used.

If the base end side of the temple is bent into a desired shape so as to abut the fixed portion of the connecting member only at a predetermined position and is rotatably supported by the connecting member, a stopper is provided at the joint portion. It is possible to prevent the temple from opening without providing it.

The bush 3 is formed in an annular shape from an appropriate material such as a synthetic resin material such as rubber or nylon, or a metal, and an annular flange 3a protruding outward is integrally formed on the upper portion. Incidentally, it goes without saying that the flange 3a regulates the drop-out when the flange 3a is inserted into the mounting hole 2b, and that the bush 3 is closely fitted into the mounting hole 2b. .

If a plurality of types of bushes (not shown) having different thicknesses and hole shapes are prepared in advance, even temples having different diameters can be replaced and the variations are rich.

On the other hand, the temple T is made of an appropriate material such as nickel or titanium, and as shown in FIGS. 3 to 5, a horizontal portion T ₁ formed by bending one end side (coupling side) inward by 90 degrees, the free end of the horizontal portion T ₁ further constitute a connecting portion from the vertical portion T ₂ Metropolitan formed by bending vertically downward, by press-fitting said from above the vertical portion T ₂ to the bushing 3, the The temple T is rotatably connected to and supported by the joint portion 2.

The hardness when the temple T is rotated (opened and closed) is determined by the frictional force between the mounting hole 2b and the bush 3 and the frictional force between the bush 3 and the temple T (specifically, the vertical portion T). ₂ can be set by the strength of press-fitting ₂ into the bush 3.

In the spectacle temple connecting structure of the rimless spectacles of the present invention constructed as described above, first, the insert portion 1 is inserted into the connecting hole L ₁ of the lens L, and then the front end surface of the joint portion 2 has the lens L.
