  However, in the rim mounting structure described in Patent Document 1, when the rim 2 is attached to the spectacles front frame 1, the spectacles front frame 1 must be largely deformed by the extent that the protrusions 21 protrude from both sides of the rim 2. In addition, depending on the material and shape of the spectacles front frame 1, it may be difficult or impossible to attach the rim 2. Therefore, there is a problem that the material and shape of the spectacles front frame 1 are limited and the design of the spectacle frame is limited.

  In order to solve such a problem, the formation position of the protrusion 21 may be selected at a position where the attachment is easy. However, if the protrusion 21 is formed at such a position, the rim 2 is easily detached. It is necessary to fix the rim 2 to the spectacles front frame 1 with S or the like. However, the process of tightening the small screw S is a heavy work load and takes time and is expensive, and the screw S is loosened while the spectacle frame is used, which tends to cause rattling of the lens. There is also a problem.

Furthermore, since the projections 21 of the rim 2 projecting to both end sides of the spectacles front frame 1 are in the way, and there is no space for inserting a metal fitting for attaching wisdom, it is necessary to extend both ends of the spectacles front frame 1 greatly. There is also a problem that this limits the means for attaching wisdom and the design of the spectacles front frame 1.
The present invention has been made to solve these problems all at once.

In order to achieve the object of the present invention, the invention according to claim 1 is characterized in that a fitting groove is formed in the inner peripheral surface of two lens holding frames provided in the spectacles front frame, and the lens is formed in the fitting groove. In the rim mounting structure for the spectacles front frame into which the rim for holding the lens is fitted, an engagement recess is formed on at least one surface or back surface of the lens holding frame on the front side or the bridge side, and the engagement is performed on the rim. An engaging claw that engages with the recess is formed.
In this case, as described in claim 2, a groove is formed in the lens holding frame so as to communicate from the rim to the engagement recess and into which the engagement claw is fitted, and the engagement claw is embedded in the lens holding frame. It is good to make it. By doing in this way, even when deformation | transformation, such as a twist, is added to the spectacles front frame, an engagement nail | claw is hard to remove | release and it can be made clear from the design. 4. The lens holding frame according to claim 3, wherein the engaging recess and the engaging claw may be either a back surface (a surface on the eye side of a spectacle wearer) or a front surface of the lens holding frame. The engagement recess may be formed on one surface of the wisdom side and the bridge side, and the engagement recess may be formed on the other back surface.

The engagement recess and the engagement claw may be formed on both the rim and the lens holding frame on both the wiping side and the bridge side, or either one. According to a fourth aspect of the present invention, a hole or a groove is formed on one of the bridge side of the fitting groove and the bridge side of the rim, and an engaging portion inserted into the hole or groove is formed on the other. You may make it form. In the case where an engaging portion is formed on the bridge side of the rim and a groove portion is formed on the bridge side of the fitting groove, a nose pad is attached to the engaging portion as described in claim 5. It can be a box foot.
Thus, if the engaging recess is formed in the lens holding frame and the engaging claw that engages with the engaging recess is formed in the rim, the deformation of the lens holding frame necessary for fitting the rim into the fitting groove is performed. The amount can be minimized, and the material, shape, and design of the spectacles front frame are not restricted.

  Further, as described in claim 6, a wisdom or wisdom attachment member or a decoration member may be attached to the engaging claw of the rim. As described above, in the rim mounting structure of the present invention, it is possible to mount the wisdom and wisdom mounting members using the engaging claws exposed on the back side of the front frame of the glasses. There is no need to extend both ends of the frame, and the design of the spectacle frame is not limited. In addition, the wiping attachment member is not exposed on the surface of the spectacle front frame, and the design of the spectacle front frame can be made clear. Furthermore, when the engaging claw is exposed on the surface of the spectacle front frame, the design of the spectacle front frame can be achieved by using the engaging claw itself as a decoration or attaching a decorative member to the surface of the engaging claw. Can be increased.

  According to a seventh aspect of the present invention, the engaging recess may be formed so as to be inclined in a direction in which the rim is lifted when the engaging claw is engaged. Further, in the case where the hole is formed in the fitting groove and the engaging portion is formed in the rim, the rim is attached when the hole or groove is engaged with the engaging portion as described in claim 8. It is good to incline in the direction of lifting. In this way, when the engaging claw is engaged with the engaging recess or when the engaging portion is engaged with the hole or groove, the rim is biased in the direction in which the rim is pressed against the fitting groove. The rim can be fixed to the lens holding frame more closely.

A connecting member that connects the two rims may be attached to a bridge that connects the two lens holding frames. The rigidity of the bridge is increased by the connecting member, and the entire rigidity of the spectacles front frame can be increased by connecting the two rims. For example, as described in claim 10, a hole or groove is formed in one of the connection member and the rim, and the hole or groove is formed in the other. It can be set as the structure which formed the engaging part inserted in. In addition, when an engaging part is formed in the rim and a groove part is formed in the connecting member, the engaging part may be a box foot to which a nose pad is attached. it can.
