Description

[Detailed description of the invention]

[0001]

[Field to which the invention belongs]

 The present invention relates to glasses for industrial use, sports use, and the like having a single spectacle lens, and more particularly, to spectacles configured to easily and securely attach a spectacle frame to a spectacle lens in a detachable manner.

[0002]

[Prior art]

 For example, in the case of industrial dustproof glasses, a lens and a frame are integrally formed of plastic, and vines are attached to both ends of the integrally formed product. Alternatively, two lenses are fitted in a plastic or metal frame. In each case, the lens may be transparent or colored, depending on the field in which the glasses are used.

[0003]

[Problems to be solved by the invention]

 In order to remove the discomfort of the glasses when worn, the weight of the glasses has been increasingly measured. Have been. Particularly, in the former case, since both ends are directly connected to the vine, it is necessary to make the integral lens or frame part robust, and further weight reduction cannot be expected. Since the latter glasses have basically the same structure as ordinary glasses, assembly of the glasses requires considerable skill. SUMMARY OF THE INVENTION An object of the present invention is to provide industrial or sports glasses that can be further reduced in weight, have a simple structure, and are very easy to assemble.

[0004]

[Means for Solving the Problems]

 According to the present invention, the eyeglass frame is composed of an elastic thin eyeglass frame and a single forwardly curved eyeglass lens having a bay-shaped nose in the center and common to both eyes. , A pair of hinges hinged to both ends of the lens support frame, wherein the lens support frame is formed to be bent downward in a U-shape at the center and folded up to form a pair of central hooks. A nose attached to a downwardly bent portion of the lens support frame adjacent to the pair of hooks, the end hook formed to protrude forward adjacent to the constructed bridge and hinge connection portion of the buckle; A single spectacle lens is provided with a pair of notches on the opposite edge of the bay-shaped nose and a slot in the portion adjacent to the end, and a pair of central hooks Notch Hooked on to provide eyeglasses comprising securing the spectacle frame Meganere lens by inserting the end hook in the slot.

[0005] The glasses frame is preferably made of a metal wire such as stainless steel or a plastic material. In a preferred embodiment of the present invention, the lens support frame of the spectacle frame is curved forward as a whole according to the curvature of the spectacle lens, and the lens support between the hinge connection with the part bent from the U-shaped downward. Each of the frame portions is bent downward to give upward elasticity, and the end hooks are inserted into the end slots of the spectacle lens with the pair of central hooks of the bridge hooked to the pair of notches. It is dimensioned so that the end hooks resiliently abut the edges of the end slots of the spectacle lens when they are inserted.

[0006]

[Embodiment of the invention]

 The spectacles according to the present invention include a thin spectacle frame 1 having elasticity and a single forwardly curved spectacle lens 2 common to both eyes. The spectacle lens is shaped so as to define a bay-shaped nose 2 ′ at its center and is preferably made of plastic and may be transparent or colored, depending on the application for which the spectacles are used. Good. The glasses frame 1 is preferably made of a metal wire frame such as stainless steel, and comprises a lens support frame 3 and a vine 5 hinged to both ends thereof. Of course, other materials, such as plastic, may be used for the megane frame. The lens support frame 3 is formed by bending downward in a U-shape at the center, and is folded forward to be forwardly adjacent to the bridge 7 and the hinge connecting portion 4 with the vine 5 forming a pair of central hooks 6, 6. The projection has an end hook 8 formed. The lens support frame 3 also includes a soft plastic piece adjacent to a pair of central hooks 6, 6 formed by the folding of the bridge 7 and bent downwards 9, 9 of the lens support frame. A pad support 11 supporting a nose pad 10 made of is fixed by welding. The single spectacle lens 2 is formed with a pair of notches 12 and 12 at opposing edges of the bay-shaped nose holder 2 'and slots 13 and 13 at portions adjacent to the ends. The spectacle frame 1 and the spectacle lens 2 are fixed to each other by locking a pair of central hooks 6, 6 into a pair of notches 12, and inserting end hooks 8, 8 into slots 13, 13.

The lens support frame 3 is curved forward in accordance with the curvature of the spectacle lens 2, and is formed from a portion bent downward in a U-shape to the hinge connection portion 4 with the temple 5 and the lens support frame. Portions 14, 14 are each bent downward to provide upward resilience. When the pair of center hooks 6 of the bridge 7 are hooked on the pair of notches 12, the portions 14, 14 of the lens support frame 3 have end hooks 8, 8 which are end slots 13 of the spectacle lens 2. , 13 are located below and somewhat outside. Thus, when the end hooks 8, 8 are inserted into the end slots 13, 13 of the spectacle lens, due to the elasticity of the portions 14, 14 of the lens support frame 3, the end hooks 8, 8 are connected to the end slots 13, 13 of the spectacle lens. , 13 elastically abuts the edges of the spectacle lens, thereby ensuring that the spectacle frame is firmly fixed to the spectacle lens and that the spectacle frame is positioned adjacent to the upper edge of the spectacle lens so as not to obstruct the view. I do. Once the spectacle frame is fixed to the spectacle lens, the spectacle lens does not accidentally come off the spectacle frame.

In the above configuration, assembling the eyeglasses, first, the description has been given of the case where the center hooks 6, 6 of the bridge of the lens support frame are hooked on the pair of notches 12, 12 of the eyeglass lens. First, the end hooks 8,8 of the eyeglass lens 2 are inserted into the end slots 13,13 of the glass lens 2, and the central hooks 6,6 of the bridge 7 of the lens support frame 3 are inserted into the pair of notches 12,12 of the eyeglass lens 2. It may be hung. In that case, the center hooks 6, 6 will be located below the pair of notches 12, 12 of the spectacle lens 2. By pushing up the bridge 7 against the bay-shaped nose of the spectacle lens, the pair of central hooks 6, 6 of the bridge 7 are engaged with the pair of notches 12, 12 of the spectacle lens 2. When removing the spectacle lens from the spectacle frame, the hooks may be removed from the notch and the slot of the spectacle lens, contrary to the above assembly.

[0009]

[Effect of the invention]

 The eyeglasses according to the present invention are designed such that the eyeglass lenses are mounted on a thin eyeglass frame by fitting the hooks with the notches and the slots, so that the assembly and detachment are easy and the whole can be made very light. it can.
