Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a spectacle frame, and more particularly to a spectacle frame which is characterized by the shape of a bridge of a rimless spectacle frame made of a nylon wire and a connecting portion between an armor and a lens.

[0002]

2. Description of the Related Art As for eyeglass frames, it is a global trend to make the rim line around the lens light and thin to improve the field of view and to make the frame inconspicuous and bright.

The ultimate form in which the rim line is made thin and light with a frame without rims does not include a member corresponding to the rim line, and the armor connected to the bridge and the temple is fixed to both ends of the lens to hold the lens. It is what The most common means for fixing a bridge or armor to a lens is to provide through holes at both ends of the lens and fasten them with screws and nuts.

Further, there is a nyroll frame shown in FIG. 5 as a spectacle frame having a thin and light rim line. The Nyroll frame holds the upper part of the lens 3 by a metal rim wire called a Nyroll bar 21, and the lower half of the lens is held by thin nylon wire rods 14 connected to both ends of the Nyroll bar. The bridge 1 and the armor 2 are welded to both ends of the Nyroll bar 21. A concave groove 15 is provided on the periphery of the lens 3, and a bottom spreading groove 22 as shown in FIG. 6 is also provided on the inner peripheral edge of the nyroll bar 21. Then, a wire made of synthetic resin having a cross-section polished shape (ny roll) is fitted in the groove 22 of the nyroll bar, and the ridge 24 formed on the inner peripheral side of the nyroll bar 21 by the nyroll 23 is provided around the lens 3. The nylon wire rod 14 connected to both ends of the Nylor bar 21 is fitted into the groove 15 of the lens, and the lower half of the lens is fitted into the groove 15 of the lens.
Holding

[0005]

The rimless glasses in which the bridge and armor are fixed to the lens with screws or the like do not hinder the field of view in the sense that there is no metal wire such as a rim wire around the lens, but the bridge does not hinder the view. If the armor is used, the appearance of the fixed part of the lens becomes bad, and there is a big drawback that the lens needs to be perforated. Since this lens drilling work is done at the final stage of sales after the lens and frame are decided, there are many cases where the equipment and skills are not always sufficient, and the lens fails due to the failure of drilling. There are many cases. Also, if you want to change the design of the glasses without changing the lens, you cannot change the design of the glasses unless you cut the periphery of the lens to the drilled position, and it is virtually impossible to change the design.

On the other hand, the Nyroll frame does not require a hole drilling process for the lens and only has a thin groove around the lens. Therefore, by cutting the periphery of the lens without exchanging the lens, the frame is formed. You can also change the design of the glasses by exchanging only them. However, since the lower half of the lens of the Nyroll frame is made of only thin nylon wire, it does not obstruct the view to the same degree as that of the rimless glasses, but the upper field of view is inferior to that of the rimless glasses due to the presence of the Nyroll bar.

According to the present invention, the lens does not need to be perforated, a wide field of view can be obtained in both the up and down directions of the lens, which is similar to that of rimless glasses, and the shape of the bridge and the connecting portion with the armored lens is small and has a good appearance. The challenge is to obtain a spectacle frame that can be shaped.

[0008]

In the spectacle frame of the present invention, the upper edge portion of the concave groove 15 in which the upper and lower nylon wire rods 13 and 14 connecting both ends of the bridge 1 and the armor 2 are provided around the lens 3 are provided. The upper and lower sides of the lens 3 are held by being fitted into the lower edge portion and the bridge 1 and the armor 2 are pressed against the peripheral surface of the lens 3 by the tension of the nylon wires 13 and 14. In the connecting portion 4 of the bridge 1 and the armor 2 with the peripheral surface of the lens, a vertical fitting groove 6 similar to that provided in the conventional nyroll bar is provided.
Is provided, and a short length of the nyroll 7 is fitted in the fitting groove 6, and the nyroll 7 is fitted in the concave grooves 15 on both sides of the lens peripheral surface. Further, a brim 9 and a connecting portion 4 of the armor 2 with the lens 3 are provided with a collar 9 extending to the front surface of the lens 3, and the inner side surface of the collar 9 is in close contact with the front surface of the lens 3.

[0009]

In the spectacle frame of the present invention, the upper and lower edges of the lens 3 are held only by the thin nylon wires 13 and 14, so that a wide field of view above and below the lens, which is free from obstructions and is similar to that of rimless spectacles. It is secured and can be made to have a bright design that is similar to rimless glasses in appearance. The bridge 1 and the armor 2 are fixed in the vertical direction (circumferential direction) with respect to the lens 3 by the tension applied from the upper and lower nylon wires 13 and 14, and are pressed against the peripheral surface of the lens 3 by the tension. Further, the ridges 8 formed on the connecting surface 4a of the bridge 1 and the armor 2 with the lens 3 by nyroll or the like are fitted into the concave grooves 15 on the lens peripheral surface, so that the front and rear direction of the bridge 1 and the armor 2 (lens The position is fixed in the direction perpendicular to the plane.

Due to the above action, the bridge 1 and the armor 2
Is held at a predetermined position on the peripheral surface of the lens 3 and holds the lens 3. However, when a force in the direction of opening the temple of the armor 2 is applied when the glasses are put on and taken off, by the lever action. A large tension acts on the nylon wires 13 and 14, and the nylon wires extend to cause the projection 8 provided at the connecting portion 4 with the lens 1 peripheral surface of the bridge 1 and the armor 2 to come off from the groove 15 of the lens, and the lens 3 falls off. Something like that happens. Therefore, in the present invention, a brim 9 extending to the front surface of the lens 3 is provided at the connecting portion 4 of the bridge 1 and the lens 3 of the armor 2 to prevent the lens 3 from falling off due to the above causes. That is, by providing the collar 9 as described above, the force for opening the temple outward is
The front of the lens pushes the front of the lens, and bridge 1 and armor 2
Will be received by the forces X, X (see FIG. 2) that try to slide the connecting portion 4 with the lens peripheral surface toward the front side of the lens, and the connecting surface 4a with the lens peripheral surface of the bridge 1 and the armor 2 will be received. The slippage is received by the fitting of the projection 8 formed of nyroll and the concave groove 15 on the lens peripheral surface, and the tension is not applied to the nylon wires 13 and 14, so that the lens is dropped due to the above-mentioned cause. Is prevented.

[0011]

1 to 4 are views showing an embodiment of the present invention. The connecting portion 4 of the bridge 1 and the armor 2 with the lens 3 has an L-shaped cross section in a plan view, and has a surface 4a that abuts on the lens peripheral surface and a surface 4 that abuts on the lens front surface.
b are formed. A fitting groove 6 similar to that provided in the conventional nyroll bar is provided on the surface 4a that comes into contact with the lens peripheral surface, and a short nyroll 7 having a short cross-section is fitted into the fitting groove 6, A vertical ridge 8 is formed. The surface 4b that comes into contact with the front surface of the lens is formed by integrally providing a short collar 9 extending to the front surface side of the lens on the front side of the connecting portion 4 with the lens of the bridge 1 and the armor 2.

The connecting surfaces 4a, 4a on the lens peripheral surfaces of the bridge 1 and the armor 2 are connected to each other by upper and lower nylon wires 13 and 14 extending on the extension of the ridge 8. Nylon wires 13 and 14 ends and bridge 1
As the structure of the connecting portion with the armor 2 and / or the armor 2, the same structure as that used in the conventional Nyroll frame is adopted. When the upper and lower nylon wires 13 and 14 are formed of a single wire, the middle portion of the nylon wires 13 and 14 is diverted from the inside of the bridge 1 or the armor 2 to the outside (see FIG. 4).

Like the lens of the conventional nyroll frame, the lens 3 is provided with the concave groove 15 on the peripheral surface, and the nylon wires 13 and 14 are fitted into the concave grooves 15 at the upper and lower edges of the lens (see FIG. 3). ), The ridge 8 is fitted in the concave groove 15 at the connecting portion of the bridge 1 and the armor 2 (FIG. 2) to hold the lens 3. When the lens 3 is held, the inner surface 4b of the brim 9 provided on the bridge 1 and the armor 2 is in contact with the front surface of the lens 3 preferably in a close contact state. In other words, the concave groove 15 of the lens, when the protrusion 8 is fitted into the concave groove 15,
This means that the collar 9 is provided at a position where it comes into close contact with the front surface of the lens.

[0014]

According to the present invention described above, a wide field of view without obstruction can be obtained in both up and down directions of the lens, which is similar to that of rimless glasses, and there is no need to make a hole in the lens, and the glasses can be worn and removed. There is an effect that it is possible to obtain a spectacle frame in which there is no risk of the lens falling off due to an external force sometimes acting from the temple, and the lens is stably held around the entire circumference thereof and the lens is not damaged when an external force is applied. is there.
