[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to eyeglasses, and more particularly to a bracket attached to a lens in rimless eyeglasses.

[0002]

[Prior art]

 Conventionally, eyeglasses have been demanded to be fit and comfortable to wear, and to be excellent from an aesthetic point of view. Due to the development of manufacturing technology and materials and further improvement in designability, nowadays, products that are extremely superior in terms of design and comfort are on the market. Particularly in recent years, diversification of customer needs and individualization have progressed in this field as well, and rimless eyeglasses that are extremely bright and light from the perspective of the original functions of eyeglasses, and that are highly fashionable are becoming mainstream in popularity. . These rimless spectacles exclude the frame that surrounds the side of the lens and fits in, and there is almost nothing that obstructs the field of view. Ordinary spectacles are equipped with a bracket (commonly referred to as "chi") for attaching a bridge or temple to the rim, whereas rimless spectacles are directly attached with a bridge or bracket to the lens. They differ in points. By the way, as a mounting method for mounting the bracket on the lens, a method using a bracket having a front surface contact portion and a side surface contact portion is currently adopted. FIGS. 6 and 7 show the conventional bracket, and FIG. 6 (a) shows a state as viewed from the lens side surface direction before deformation of the side surface abutting portion, and FIG. 6 (b) shows The state seen from the lens surface direction before the side contact portion is deformed is shown. FIG. 7A shows a state as seen from the side surface of the lens after deformation of the side contact portion, and FIG. 7B shows a state as seen from the surface of the lens after deformation of the side contact portion. As can be seen from the figure, this conventional bracket 1 includes a main trunk portion 11 and a surface contact portion 12 and a side surface contact portion 13 extending from one end of the main trunk portion 11 (the surface contact portion is a side surface portion). The side surface contact portion is contacted with the lens side surface 4B, and the surface contact portion is contacted with the lens surface 4C. It is fixed by using. A hinge (not shown) is fixed to the other end of the main trunk so that the temple can be rotatably attached by a screw shaft. Normally, when using eyeglasses, first grab the temples with both hands and once wear them while widening the face and widening. Even if it is held with one hand, the temple is opened after opening it wide-angle wider than the face width and then put on. In such a bracket, when trying to open the temple to a wide angle in this way, the force is also transmitted to the side surface abutting portion and receives the outward opening force (see Fig. 7 (a)), and the lens side surface The side contact portion and the side contact portion are separated from each other to form a gap. This kind of force is applied to the temples each time the eyeglasses are used, so the angle between the front and side contact parts remains open during long-term use, and This results in a permanent gap between the side abutments. Therefore, the bracket becomes easy to move along the side surface of the lens (see FIG. 7B), and there is looseness between the lens and the bracket, so that the fixing is not effective. For this reason, periodical repairs are often required in a relatively short period, which is extremely troublesome. For these reasons, the rimless spectacles have many advantages, but have been esteemed, and there has been a demand for rimless spectacles having brackets that can be securely fixed without rattling.

[0003]

[Problems to be solved by the device]

 The present invention is intended to solve the above problems. That is, it is an object of the present invention to provide a bracket that does not rattle with a lens even if it is used for a long period of time.

[0004]

[Means for Solving the Problems] However, as a result of earnestly researching such problems, the inventors of the present invention have found that, in the bracket, another independent contact member is provided on the surface facing the lens. It was found that the adoption of this method prevents the side contact portion from opening, and the present invention has been completed based on this finding. That is, the present invention has a main portion, a surface abutting portion and a side surface abutting portion extending from the end thereof, the side surface abutting portion abutting on the side surface of the lens, and the surface abutting portion on the surface. In a bracket for rimless spectacles that abuts and fixes the front surface abutting portion and the lens by using a screw tool, a bra provided with a back surface abutting body for gripping and fixing the lens with the front surface abutting portion. Exists in Kett. The front surface abutting portion exists in the bracket extending to the main trunk portion through the side surface abutting portion. Also, the bracket in which the side contact portion extends to the main trunk through the front contact portion. Also, the back surface contacting body is detachable from the side surface contacting portion. And, again, a bracket in which the end of the back contact body is fixed to the main trunk. Further, the back contact body is made up of an elastic body for elastically pressing the lens surface, and the end portion of the bracket is fixed to the main portion.

[0005]

[Action]

 With the above-described configuration, the back surface contact body of the bracket prevents the side surface contact portion from separating from the lens, so that rattling does not occur between the lens and the bracket.

[0006]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings with reference to specific embodiments. Hereinafter, the fastener used to attach the bracket 1 and the lens R to each other is referred to as a screw tool 5, and the screw tool 5 includes a screw 51 (or a bolt) and a nut 52, and a washer, if necessary. It is meant to include accessories such as washers and spring bodies. In addition, the material of the bracket is a metal material such as stainless steel, iron, chromium, copper, nickel, zinc, aluminum, manganese, gold, titanium, cobalt, etc., or alloys or plastic materials combining some of them. For example, celluloid, acetate, polyamide, epoxy, etc. are adopted. FIG. 1 shows a first embodiment of the present invention and is a view showing a disassembled state before the bracket 1 is attached to the lens R. FIG. 2A shows a state as seen from the lens side surface side when the bracket 1 is attached to the lens R in the first embodiment, and FIG. 2B shows a state as seen from the lens surface side. It is a thing. The main trunk portion of the bracket is bent at a substantially right angle, and its end is fixed to an intermediate position of the surface 13D of the side surface abutting portion 13, and the end surface 13B on one side of the side surface abutting portion 13 is bent at a right angle. The surface contact portion 12 is provided upright. Therefore, the front surface contact portion 12 is formed to extend to the main trunk portion 11 via the side surface contact portion 13. A projecting portion 13A is provided on the other end surface 13C of the side surface abutting portion 13, and the projecting portion 13A is to be fitted into the back surface abutting body 2 as described later. A hinge 14 is fixed to the other end of the bracket, and the hinge and a temple (not shown) are rotatably attached by a screw shaft or the like. The main portion 11, the front surface contact portion 12, and the side surface contact portion 13 can be integrally manufactured by casting or welding. A back surface contact body 2 is arranged on the opposite side of the front surface contact portion 12 with the lens in between. The back surface contact body 2 plays an important role in the present invention. The back contact member 2 is formed of a plate-shaped member having holes at both ends, and one first hole 2A is to be fitted and attached to the protruding portion of the side contact member and the other second hole. 2B is a hole for inserting the screw tool 5. Here, in order to attach the bracket to the lens, first, the side contact portion 13 of the bracket is brought into contact with the side surface 4B of the lens, and the surface contact portion 12 is brought into contact with the surface 4C of the lens. Then, the back surface abutting body 2 is brought into contact with the back surface 4D of the lens, the lens is sandwiched between the front surface abutting portion 12 and the back surface abutting body 2, and fixed by the screw tool 5. That is, the first hole 2A of the back surface contact body 2 is fitted into the protruding portion 13A of the side surface contact portion 13, the hole 12A of the front surface contact portion 12 and the lens hole 4A, and the second hole 2B of the back surface contact body 2 are inserted. The screw 51 is inserted into and the nut 52 is tightened. By doing so, even if a force is applied to the temple, the protrusion 13A of the side surface abutting portion 13 is fitted in the back surface abutting body 2, so that a force to open the temple in a wide angle is applied. Also, the side contact portion 13 can be prevented from leaving the lens, and no gap is formed between the side contact portion 13 and the lens side surface.

FIG. 3 shows a second embodiment and is a diagram showing a disassembled state before the bracket is attached to the lens. FIG. 4A shows a state as seen from the lens side surface side when the bracket is attached to the lens in the second embodiment, and FIG. 4B shows a state as seen from the lens surface side. As in the first embodiment, the main trunk portion 11 of the bracket is bent at a substantially right angle, and its end is fixed to an intermediate position on the surface of the side surface abutting portion 13, and one side of the side surface abutting portion 13 is fixed. The surface contact portion 12 is erected at a right angle from the end surface 13B. Therefore, the front surface contact portion 12 is formed to extend to the main trunk portion 11 via the side surface contact portion 13. Further, a hinge 14 is fixed to the other end of the bracket, and this hinge and the temple 15 are rotatably attached by a screw shaft 16 or the like, as in the first embodiment. . On the other hand, the back surface contact body 3 is arranged on the opposite side of the front surface contact portion 12 with the lens in between. This back surface contact body 3 is a linear body having a hole at one end. It is made, and the other end is fixed to the main trunk 11 before the hinge 14. Here, in order to attach the bracket 1 to the lens R, first, the side surface contact portion 13 of the bracket is applied to the lens side surface 4B, and the surface contact portion 12 is applied to the lens surface 4C. Then, the back surface abutting body 3 is brought into contact with the back surface of the lens, and the lens is sandwiched between the front surface abutting portion 12 and the back surface abutting body 3 and fixed by the screw tool 5. That is, the screw 51 is inserted into the hole of the front surface contact portion 12, the lens hole 4A and the hole 3A of the rear surface contact body 3 and fixed by the nut 52. Even if a force is applied to the temple to open it outwardly at a wide angle, since the back surface contact body 3 is fixedly installed between the main trunk portion 11 and the lens, the opening operation of the bracket can be prevented. Therefore, the side surface abutting portion 13 does not separate from the lens side surface 4B and no gap is generated. In the rimless spectacles, the bracket may come off the lens due to the bolt coming off when the nut comes off. However, in the case of the second embodiment, the rear surface abutting body 3 has the front surface abutting portion 12 even if the nut is removed. Since the lens R can be held between the lens and the lens, the lens does not accidentally come off from the bracket. Although the thickness of the lens changes depending on the strength of the lens, if the back contact member 3 having elasticity is used, the lens pressing position has a degree of freedom, and the lens thickness is sufficiently adapted. be able to.

FIG. 5A shows a third embodiment, and is a view showing a state as seen from the side surface of the lens when the bracket is attached to the lens. In the first embodiment, the end portion of the main trunk portion 11 is fixed to an intermediate position on the surface of the side surface contact portion 13, whereas in the case of this embodiment, the main trunk portion 11 is removed from the surface contact portion 12. The difference is that it extends and extends. The mounting method of the back contact member 2 is the same as in the first embodiment. Therefore, even if a force that opens the temple at a wide angle is applied, it does not directly act in the direction in which the side surface abutting portion 13 is separated from the lens side surface.

FIG. 5B shows a fourth embodiment, and is a view showing a state as seen from the side surface of the lens when the bracket is attached to the lens. In the second embodiment, the end portion of the main trunk portion 11 is fixed to an intermediate position on the surface of the side surface contact portion 13, whereas in this embodiment, the main trunk portion 11 extends from the surface contact portion 12. It is growing. Further, the mounting method of the back contact member 3 is the same as that in the second embodiment. Therefore, even if a force to open the temple at a wide angle is applied, it does not directly act in the direction of separating the side surface contact portion 13 from the lens surface.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other modifications can be made without departing from the essence thereof. Nor. In the first embodiment, for example, the projecting body is provided on the side surface abutting portion 13, but it may be provided on the back surface abutting body 2 and the hole may be provided on the side surface abutting portion 13, as long as both are removable. Good. The shape of the protrusion is not limited as long as the two fit into each other. In the second embodiment, one end of the back contact member 3 may be provided anywhere on the main trunk 11, and in an extreme case, it may be fixed to the hinge.
