DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a frame element in rimless spectacles, and more particularly, to a rimless spectacle, a temple bracket for mounting a temple to a lens and a connecting bracket for connecting two lenses. The present invention relates to a structure for attaching a frame element, which is a bridge, to a lens.

[0002]

2. Description of the Related Art Conventionally, there has been a demand for spectacles that are comfortable to wear, such as fit and wearing, and that are excellent from an aesthetic point of view. The manufacturing technology and the material have been developed, and further, by designing, etc., products which are extremely excellent in both design and wearing comfort are now on the market.

[0003] One of such glasses is rimless glasses in which a rim around a lens is omitted. In the rimless glasses, frame elements such as a temple bracket (usually referred to as "chi") for rotatably attaching the temple to the lens and a bridge for connecting the two lenses are conventionally as follows. Was fixed to the lens. That is, since there is no rim in the rimless glasses, the temple bracket and the bridge are fixed to the lens via the mounting bracket. The mounting bracket includes a surface contact portion that contacts the surface of the outer peripheral portion of the lens, and a side contact portion that contacts the side surface of the lens.

[0004] On the other hand, a through hole is provided in the outer peripheral portion of the lens. The mounting bracket is fixed to the lens by screws inserted into the through hole and the connection hole provided in the surface contact portion, and the temple bracket and the bridge are fixed to the side contact portion of the mounting bracket by brazing. The mounting bracket is a member for indirectly fixing the temple bracket and the bridge to the lens, and at the same time, has a function of preventing the rotation of the temple bracket and the bridge by pressing the side surface of the lens with the side contact portion. It is a member. However, according to the above-described conventional mounting structure, the opening / closing stress of the temple, which occurs when the eyeglasses are mounted, is directly transmitted to the mounting bracket.

For this reason, if the spectacles are used for a long period of time, the surface contact portion and the side contact portion of the mounting bracket are deformed, and rattling occurs with the lens surface. As a result, the force for pressing the side surface of the lens is weakened, and the mounting bracket is rotated around the connection hole, causing loosening of the screw. Further, according to the conventional mounting structure as described above, the mounting bracket needs to have a strength that can withstand the opening and closing stress of the temple. For this reason, if the positioning of the mounting bracket and the lens is inaccurate, as a problem before the deformation of the mounting bracket, a problem of lens cracking due to direct transmission of the opening and closing stress of the temple to the lens has occurred. The present invention has been developed against this background.

Although the present invention has been described above, the present invention is not limited to the embodiment, and various modifications as exemplified below can be made without departing from the essence of the present invention. Not even. (1) In the above embodiment, the case where the frame element is a temple bracket has been described. However, it goes without saying that the present invention can be applied to a case where the frame element is a bridge. Further, the material of the frame element and the rotation preventing member is not limited to metal, and plastic or ceramic can be sufficiently used except for the merit that brazing is not required. (2) In the above embodiment, the fixing means for fixing the temple bracket to the lens also functions as the means for fixing the rotation preventing member to the lens, but the fixing means for the rotation preventing member is separately provided. Even if provided, the intended object of the present invention can be achieved. However, as in the above-described embodiment, it is possible to reduce the number of parts and man-hours by using a single fixing means for both members. (3) In the above-described embodiment, the fitting portion is formed by the groove between the pair of walls.
This may be used as a fitting portion. Further, a plurality of protrusions may be provided on one of the temple bracket and the rotation preventing member, and a plurality of holes may be provided on the other, and these may constitute a fitting portion. ( 4 ) In the above Examples 8 to 11, the lower surface of the temple bracket is in contact with the side contact portion, but the material of the rotation preventing member is a relatively hard linear member, which can sufficiently hold the shape. If so, the temple bracket may directly contact the lens side surface by partially omitting the side contact portion. In this case, as described above, an open loop-shaped linear member is used.
