Abstract

(57) [Abstract] [Purpose] Glasses in which the left and right lenses are connected by a connecting member without using a rim for holding the lens, and a wrench is screwed on the outside of the lens. Provide eyeglasses that will not crack or break in the screw holes of the lens due to the external force that acts when opening the lens. [Structure] Although the basic form of glasses is the same as before,
In the lens 1, a grid body 15 in which a wire having a thickness of a micron unit is formed in a grid shape is embedded over the entire surface or limited to the outer peripheral area.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to spectacles which are configured by fixing both lenses with a connecting member with screws without using a rim for holding the lenses, and by fixing a roy roy on the outside of the lenses.

[0002]

[Prior art]

 In general eyeglasses, a lens is attached to an eyeglass frame, and the eyeglass frame has a rim for fixing the lens. However, in recent years, glasses that do not use rims such as those mentioned above have been widely used. That is, the left and right lenses are directly connected by a connecting member, and the outside of the lens is fixed with screws. The connecting member and the lens are also fixed by screws, and therefore, the lens has a screw hole through which the screw is inserted.

Although the screw penetrates through the screw hole to connect the lens and the connecting member and the end piece, there are many cases where the screw hole is cracked and damaged by the action of an external force. Of course, since the resin washer is fitted in the screw hole, the metal surface of the screw does not come into direct contact, but the damage rate of the lens is higher than that of glasses with a rim. This is a big problem for this type of glasses.

[0004]

[Problems to be solved by the present invention]

 As described above, the eyeglasses formed by directly connecting the lens to the connecting member and the end piece without using the rim have the above problems. The problem to be solved by the present invention is this problem, and it provides eyeglasses of this type in which the lens is not chipped or damaged.

[0005]

[Means for Solving the Problems]

 The glasses of the present invention are a type of glasses that do not have a rim for holding a lens, and the basic form is the same as conventional ones. That is, both the left and right lenses are connected by a connecting member, and the roy roy is screwed to the outside of the lens. Here, there is no limitation on the specific connecting structure when the connecting member and the endpiece are connected to the lens.

Further, in the present invention, in order to prevent the lens from being damaged, a grid body in which reinforcing wires made of an extremely thin metal wire having a thickness of a micron unit or other material is formed in a grid shape is embedded inside. The lens is a molded lens made of plastic, and the lattice body is embedded at the same time as molding. The area to be embedded may extend over the entire surface of the lens or may be limited to the outer peripheral portion where the connecting member or the rail is screwed. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 is an embodiment showing a pair of glasses according to the present invention. In FIG. 1, 1 is a lens, 2 is a connecting member, and 3 is an endowment. Has been done. Then, the vine 4 is connected to the tip of the armature 3 via a hinge 5 so as to be folded. Further, below the connecting member 2, inside the lenses 1 and 1, nose pads 6 are attached.

Although the connecting member 2 and the lens 1 are screwed together, there is a contact piece 8 that comes into contact with the outer peripheral surface 7 of the lens 1, and the fixing piece 9 is extended outward from the corresponding piece 8. There is. In other words, the outer periphery of the lens 1 is fixed by the contact piece 8 with screws, and the screw 10 provided at the tip of the attachment piece 9 penetrates the screw hole formed in the lens 1 and It is tightened with a nut on the side.

FIG. 2 is a cross-sectional view showing a connection state between the armor 3 and the lens 1. Although the screw 10 penetrates the screw hole 11 of the lens 1, the metal screw 10 directly contacts the lens 1. The washer 12 made of resin covers the area from the lens surface to the screw hole so as to prevent contact between the fastening piece 9 and the screw 10. Also, a resin washer 14 is also interposed between the nut 13 provided on the back side of the lens.

By the way, if the temple 4 is opened when wearing glasses, a moment M about the screw 10 acts on the armature 3, and this moment M directly acts on the hole 11 of the lens 1. A crack is generated in the screw hole 11. The present invention is intended to prevent lens breakage in this type of spectacles, and ultra-fine wire rods are embedded in the lens 1 in a grid pattern. That is, the wire rod has a thickness of a micron unit, and is a lattice body sufficient to improve the strength of the lens without obstructing the field of view.

FIG. 3 shows a lens in which the grating body 15 is embedded. Here, the grid 15 is a grid of an extremely thin wire as described above, and the material is metal, carbon fiber or the like. Then, not only the case where the entire surface of the lens 1 is embedded, but the case where the lens 1 is embedded only in the outer peripheral portion may be used. Of course, since the lens 1 is a plastic molding lens, it will be molded to a certain size at the time of molding, and it will be cut into an appropriate shape later, but the outer peripheral portion of the circular molded lens is removed by cutting. Even so, the area is such that the above-mentioned lattice 15 remains.

By the way, the method of embedding the lattice 15 is arbitrary. For example, as shown in FIG. 4, a film 16 having the lattice 15 embedded or adhered is separately manufactured, and the film 16 is used as a mold. The plastic base layer 17 is molded in the set state. That is, the film 16 and the plastic base layer 17 are laminated to form a lens, and the film 16 must be a surface having a binding property to the plastic base layer 17 in a liquid state.

The glasses of the present invention are constructed by using the lens 1, and the connecting structure of the lens 1, the connecting member 2 and the end piece 3 is not particularly limited, and the embodiment shown in FIGS. Is just one specific example. For example, the pin 8 may be protruded from the fastening portion 9 and fitted into the groove formed on the lens surface without having the contact piece 8 that contacts the lens outer peripheral surface 7. That is, the screw 1 and the pin are fixed so that the lens 1 does not rattle.

Alternatively, the screw hole and the screw cross section of the lens 1 may be formed into a polygonal cross section so that the lens 1 does not rotate around the screw 10. As described above, the eyeglasses of the present invention are directly connected by a connecting member without using a rim, and screws are screwed to the outside of the lens. With the body embedded, the following effects can be obtained.

[0015]

[Effect of device]

 The glasses of the present invention are of a type in which the left and right lenses are connected by a connecting member without using a rim, and the armature is screwed to the outside of the lens, but since the lens body is embedded in the lens. Moreover, damage to the lens can be prevented. That is, it is possible to suppress the occurrence of cracks in the screw holes of the lens due to the moment acting when the temple is opened and closed.
