Description

Lens Combination Bracket of Rimless Glasses {COUPLING BRACKET FOR RIMLESS EYEGLASSES LENS}

The present invention relates to an improvement of a frameless lens coupling bracket, in particular, the manufacturing of the lens coupling bracket is simple, the welding structure between the lens connection is not only robust, the replacement of the resin plug connecting the lens and the bracket when replacing the lens Is to make it quick and easy.

In general, glasses are provided with various types of products, and commonly used glasses are composed of a lens frame and a leg, and a lens is used in combination with the lens frame.

Therefore, in the case of the glasses, the lens frame for supporting the lens is visually exposed, so that the wearing state of the glasses is clearly revealed, and the weight of the glasses is weighted by the weight of the lens frame, so that the user's nose is pressed during wearing. There was an uncomfortable feeling such as decreased fit and pain.

As a means for preventing such closure, eyeglasses having a good wearing feeling because the wearing state of the glasses are not visually impaired may be referred to as rimless glasses.

In the case of the rimless glasses, since there is no lens frame, various configurations are provided as a means for coupling the lens and the connection between the connection between the lens and the lens, or the connection between the lens and the glasses legs.

As an example, the configuration of the lens coupling bracket (1), as shown in Figure 10, the bracket (1) is welded between the connection, and the coupling hole in which the bracket (1) is fitted to the lens After constructing in the hole, the resin plug is inserted from the rear lens coupling hole, and in the above state, the coupling rod (2) of the bracket (1) in front of the lens coupling hole to be coupled to the lens.

In the case of the bracket 1 used above, the flat iron plate is cut into a "c" shape by a wire cutting method, and the cut material is pressed to form a triangular protrusion (3) shape.

Therefore, the cross-section shape of the fastening bar (2) of the bracket is formed in a square shape, and the triangular protrusion (3) irregularities are formed on the fastening bar (2) of the square column shape, and then the resin plug is inserted into the coupling hole of the lens. When the brackets (1) to be fitted to join them, there was a closed end that the flow phenomenon occurs without the lens firmly supported by the fastening rods (2) of the square pillar shape while wearing the rimless glasses.

In particular, there is a lot of difficulty in cutting a square iron plate into a "c" shape using a wire cutting method, and the resin for lens replacement in the state in which the triangular protrusion (3) formed through press processing is combined with a resin plug. When the plug was to be removed, the back of the resin plug had to be pulled out with tongs, which made it difficult to replace the lens.

As another means in addition to the bracket of the above-described configuration, there are provided products in which a convex-convex fastening rod is separately prepared and welded to the bottom plate constituting the bracket, but the fastening bars are symmetrically welded side by side on the bottom plate. Not only did the work require precision, but also the work was inferior.

In the case of the conventional lens coupling bracket mentioned above, the manufacturing process is generally complicated and the manufacturing cost increases, and there are also disadvantages such as difficulty in separating the resin plug from the bracket when the lens is replaced. It was.

The present invention, in order to correct the above-mentioned disadvantages in the construction of the lensless bracket for rimless glasses, the production is simple, the connection between the bracket and the bracket and the structure of the bracket and the lens combination, as well as the replacement of the lens It is to be made easily.

As a means for solving the above problems, the present invention cuts a predetermined length of a circular wire, and then forms a spiral portion at both ends using a rolling machine, presses the wire formed with the spiral portion to form a flat portion at the bottom of the central portion, and simultaneously forms both ends. The bending rod formed by the spiral is vertically bent so that the fastening rod is formed upright, and the bracket for lens fastening is constructed, and the welding is configured between the connection between the lens and the lens or the connection between the lens and the bridge using the bracket. The welded bracket is inserted into the resin plug inserted in the lens coupling hole to be coupled to the lens and the bracket to be integrally fixed.

According to the present invention, when constructing a lens coupling bracket of a rimless glasses, a circular wire is cut to a certain length, the cut iron wire is formed to have spiral portions at both ends by a rolling machine, and the spiral wire is formed by bending a spiral wire to form a lens coupling. By constructing the bracket and welding the lens coupling bracket between the lens coupling connections of the frameless glasses, the manufacturing of the lens coupling bracket can be made simple, thereby reducing the manufacturing cost and spiraling the bracket. In the process of bending the formed iron bar by the press, a flat portion is formed at the center of the bottom to widen the contact area between the connections, and to be welded side by side vertically on the connections so that the coupling with the lens can be made at the correct position. Next, to ensure a solid assembly with the resin plug fitted in the lens coupling hole, In addition, when the lens is replaced, cutting the center of the resin plug and then pinching with a forceps to rotate the resin plug can be easily removed while rotating along the spiral, so that the lens can be replaced easily.

The length of the fastening rods 14 is about 2.7 to 3.5 mm, preferably about 3 mm, but the length of the fastening rod 14 is about 3.5 mm, preferably 3.4 mm. The average dimensions can be satisfied so that most rimless glasses 40 can be applied without difficulty.

When using the lens coupling bracket 10 of the present invention to combine the lens 30 of the rimless glasses 40 and to replace the lens 30 may be replaced as follows.

First, the connection part 22 of the resin plug 20 inserted into the coupling hole 31 of the lens 30 is cut and separated, and then the connection part 22 cut by a tool such as a forceps is pinched and fixed, and the spiral 12 When the connecting portion 22 is rotated in the unwinding direction of the joint, the insertion tube 21 of the resin plug 20 is rotated along the helix 12 of the fastening rod 14, and thus, the insertion part 31 of the lens 30 is simple. Are separated.

When the separation of the resin plug 20 is completed from the lens 30 as described above, the new resin plug 20 is inserted into the coupling hole 31 of the new lens 30, and then the lens coupling bracket 10 is inserted into the resin plug. The lens 30 and the lens coupling bracket 10 are firmly coupled to the insertion tube 21 of the 20 to complete the coupling of the frameless glasses 40.

In particular, when constructing the lens coupling bracket 10 of the present invention, the planar portion 15 formed on the bottom surface of the connecting piece 13 is the connecting piece 13 when the lens coupling bracket 10 is to be welded to the connecting rod 50. Positioning the flat portion 15 of) in the connecting rod 50 not only widens the contact area by the flat portion 15, but also allows the lens coupling bracket 10 to tilt left and right on the connecting rod 50. Without being placed side by side in a vertically aligned state, when welding in the above state the welding position is made exactly, in particular, the weld 51 is a side space portion of the connecting rod 50 and the lens coupling bracket 10 It can be injected more firmly to ensure their welding.
