DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail below with reference to the embodiments shown in the accompanying drawings. FIG. 1 is an enlarged exploded view of a connecting portion between a lens and a temple of spectacles to which the present invention is applied, and FIG. 2 is an enlarged view of a connecting portion between a lens and a bridge of the spectacles to which the present invention is applied. FIG. 3 is an exploded explanatory view, and FIG. 3 is a perspective view of eyeglasses configured by applying the present invention.

First, the structure of a connecting portion between a lens and a temple of spectacles constituted by applying the present invention will be described with reference to FIG. The lens coupling mechanism of the glasses of the present embodiment is the lens 1
, Connecting body 2, crimping body 3, and temple 4. The lens 1 is provided with a through hole 11.
In the connecting body 2, a lens edge contact plate 21 that is in contact with the edge of the lens 1 and supports the lens 1 from the side surface is formed. Then, a joint portion 23 formed so as to be inserted into the through hole 11 of the lens 1 is provided substantially at right angles to a take-out portion 22 taken out from one side surface of the lens rim contact plate 21,
In addition, a joint 24 is protruded from the other side surface of the lens edge contact plate 21, and fastening holes 25 and 26 are formed at ends of the joints 23 and 24.
Has been drilled. As a material of the connecting body 2, an engineering plastic having elasticity such as polyphenylene sulfide (PPS) resin can be selected. The crimping body 3 has a head portion 31 and a shaft portion 32. By applying various decorative patterns to the head portion 31, a one-point design can be easily formed. Further, if the shaft portion 32 is tapered and formed to be pointed toward the tip, the shaft portion 32 can be inserted more smoothly. As the material of the crimp body 3, a plastic such as hard vinyl chloride can be selected. An insertion portion 41 is formed at one end of the temple 4. If the insertion portion 41 is tapered and formed to be pointed toward the tip, the insertion can be performed more smoothly. Here, as shown in FIG. 1, the joint 23 of the connector 2 is inserted into the through hole 11 of the lens 1,
The shaft portion 32 of the crimping body 3 is press-fitted into the fastening hole 25 of 23, and the insertion portion 41 of the temple 4 is press-fitted into the fastening hole 26 of the joint portion 24 of the connecting body 2. By wearing the lens 1, the lens 1 and the temple 4 can be connected. Therefore, a screwless lens connecting mechanism for rimless spectacles can be realized without using any small screws.

Next, the structure of the connecting portion between the lens and the bridge of the spectacles constituted by applying the present invention will be described with reference to FIG. The lens connecting mechanism of the spectacles of this embodiment is almost the same as that of the above embodiment, except that the bridge 5 is used instead of the temple 4. An insertion portion 51 is formed at one end of the bridge 5. If the insertion portion 51 is tapered and formed to be pointed toward the tip, insertion can be performed more smoothly. Here, as shown in FIG. 2, the joint 23 of the connecting body 2 is inserted into the through hole 11 of the lens 1,
The shaft portion 32 of the crimping body 3 is press-fitted and fitted into the fastening hole 25 of the joint portion 23, and the fastening hole of the joint portion 24 of the connecting body 2 is also attached.
The lens 1 and the bridge 5 can be connected by press-fitting and inserting the insertion portion 51 of the bridge 5 into the 26. Thus, when the lens 1 is connected to the bridge 5 and the temple 4, rimless glasses as shown in FIG. 3 are completed.

Although the embodiments of the present invention are generally as described above, the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims. For example, the screwless lens connecting mechanism of the present embodiment can be adopted for both the lens and the temple and the bridge, but if necessary, use the screwless lens connecting mechanism for either one of the Another type of lens connection mechanism can be used for one connection. In this embodiment, although engineering plastic is used as the material of the connecting body,
It is also possible to employ engineering plastics for temples, bridges, and other eyeglass parts to produce light eyeglasses having excellent strength. It goes without saying that any of these modifications fall within the technical scope of the present invention.

[0013]

As described above with reference to the embodiments, according to the present invention, the lens and the temple or the bridge of the rimless eyeglasses can be used without using any small screws required for manufacturing conventional rimless eyeglasses. Can be easily and quickly connected to each other, so that the work efficiency is extremely improved and the cost can be greatly reduced. In addition, since one-point design can be easily applied to the hole of the lens, rimless spectacles having excellent decorativeness can be obtained. Therefore, industrial practical value becomes large.
