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 wipe out 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 common to both eyes, and the eyeglass frame is hinged to both ends of the lens support frame portion. The lens support frame has a central hook protruding forward and end hooks protruding laterally and outwardly, and a nose pad on the central hook. The single spectacle lens is provided with a slot in a portion adjacent to a center portion and an end portion, and a center hook and an end hook are inserted into the slots respectively to fix the spectacle lens to the spectacle frame. Provide glasses. The eyeglass frame is preferably made of a metal wire such as stainless steel or a plastic material.

[0005] The lens support frame portion of the spectacle frame as a whole bends forward according to the curvature of the spectacle lens, the portion of the lens support frame portion between the center hook and the end hooks respectively curves upward, and The end hook is dimensioned so that when the end hook is inserted into the end slot of the spectacle lens, the end hook elastically contacts the outer edge of the end slot of the spectacle lens.

[0006]

[Embodiment of the invention]

 The spectacles according to the present invention comprise a thin elastic spectacle frame 1 and a single forwardly curved spectacle lens 2 common to both eyes, and the spectacle frame 1 is preferably made of metal such as stainless steel. It is made of a wire frame and comprises a lens support frame portion 3 and a vine 5 hinged to both ends thereof. Of course, other materials, such as plastic, may be used for the eyeglass frames. The spectacle lens is preferably made of plastic and may be transparent or colored, depending on the application for which the turret is used. The lens support frame portion 3 has a central hook 6 protruding forward and end hooks 7, 7 protruding laterally and outwardly. The central hook 6 is made of a soft plastic on the rear side thereof. The pad support 9 supporting the nose pad 8 is fixed by welding. The pad support 9 is also preferably made of a thin and resilient stainless steel wire similar to that of a magne frame. The lens support frame 3 is curved forward corresponding to the curvature of the spectacle lens 2, and the portions 10 and 10 of the lens support frame 3 between the center hook and the end hook 7 are each curved upward. Not to obstruct the view, and give the frame elasticity as described later. The eyeglass lens 2 has slots 11, 12, 12 for receiving the central hook 6 and the end hooks 7, 7, respectively, of the lens support frame at positions adjacent to the center and the end. The part 10, 10 of the lens support frame part 3 between the central hook and the end hook 7 fits the central hook 6 into the central slot 11 of the spectacle lens 2 and connects said end hooks 7, 7 to the end slots 12, When inserted into the eyeglass frame 12, respectively, the elasticity of the eyeglass frame causes the end hooks 7, 7 to be dimensioned and shaped to elastically abut the outer edges 13, 13 of the end slots 12, 12 of the eyeglass lens. ing.

Since the present invention is configured as described above, the center hook 6 is fitted into the center slot 11 of the spectacle lens, and then, while being slightly bent between the center hook 6 and the end hook 7, The end hooks 7 are fitted into the end slots 12 of the spectacle lens 2, respectively. As a result, elasticity is imparted to the portions 10 and 10 of the lens support frame portion 3, whereby the end hooks 7 and 7 are strongly pressed against the outer edges of the end slots 12 and 12 of the spectacle lens 2 and are caught. The lens does not accidentally come off the frame. To remove the spectacle lens from the spectacle frame, the hooks should be pulled out from the spectacle slots, contrary to the above assembly.

[0008]

[Effect of the invention]

 Since the spectacle lens according to the present invention is configured such that the spectacle lens is attached to the thin spectacle frame by fitting the hook and the slot, it is easy to assemble and detach, and the whole can be made very lightweight.
