Description

  The present invention relates to a spectacle frame having a rim in which a lens is fitted by combining a high-strength yarn such as water yarn with a rim portion.

  FIG. 7 shows a conventional general metal eyeglass frame, which is attached to both sides of the front part (A) via hinges (C) and (C) so that the cranes (B) and (C) can be folded. ing. The front part (a) is connected to both rims (d) and (d) by connecting members (e), and the outer parts of both rims (d) and (d) are armored (f) and (f). It is brazed and has a nasal pad (g) and (g) attached inside the rims (d) and (d).

  In this way, the lens is held by fitting to the rim (d), (d) forming the ring body, and brazed to the end of the cut so that the cut of the rim (d), (d) is not opened (illustration shown) (None) has a screwed structure. Accordingly, when attaching or detaching the lens, the screw of the broach is loosened, but some spectacle frames are not provided with this broach. For example, the eyeglass frame shown in FIG. 8 is not provided with a broach.

  In the glasses frame, half rims (chi) and (chi) that are curved in an approximately arc shape are connected by a connecting member (e), and water threads (re) and (re) are connected to the half rims (chi) and (chi). ing. The lens (n) is held by a half rim (chi) and a water thread (li). In this case, the water thread (re) is connected to both ends of the half rim (h), but when the lens (n) is fitted, the water thread (re) must be slightly stretched and attached.

  Glasses are designed in various ways for use on the face. In many cases, it is impossible to use a broach as shown in FIG. 8 to form this design. Of course, the field of view can be expanded by using half rims (Chi) and (Chi). Further, as a rim shape of the spectacle frame, there is known a rim shape in which a part of the outer periphery of the lens forms a space that is not restrained by the rim. ) Is easy to come off. Therefore, as a measure for preventing the lens from coming off, a structure can be adopted in which the outer periphery of the lens is constrained by stretching a water thread in the rim space.

  By the way, the water thread is thin and has high tensile strength, and it can be fitted in the groove formed on the outer periphery of the lens, so it does not appear on the appearance and the design is not impaired, but the water thread is fitted in the outer groove of the lens. In many cases, the work is not easy, and sometimes the lens surface is scratched or the frame is scratched. That is, both ends of the water thread are inserted and fixed through two small fastening holes provided in the frame, and a lens is fitted so as to slightly stretch the water thread. Of course, there may be one fastening hole for the water thread.

  As described above, when a lens is fitted to a rim formed by combining water threads, there are problems as described above. The problem to be solved by the present invention is this problem, and provides a spectacle frame in which the lens can be easily attached without scratching the lens and the frame.

  The eyeglass frame according to the present invention comprises a rim composed of a combination of a rim portion and high tension yarn such as water yarn, and a lens is fitted to the rim. By the way, in the case of the conventional half-rim type eyeglass frame, a broach is connected to the tip of the high-tension yarn, and the broach is fixed to the rim by screwing. Therefore, when the screw is loose, the lens can be easily fitted without extending the high-tensile yarn, and the broach is screwed after the fitting.

  On the other hand, in the case of a spectacle frame in which the rim is composed of an upper rim portion and a lower rim portion and forms a space that does not restrain the lens outer periphery between the upper and lower rim portions, High tension yarn is stretched. Then, both ends of the high tension yarn are fixed to the upper rim portion and the lower rim portion, and a broach is provided at the butt end of the upper rim portion and the lower rim portion. By screwing the broach, the high tension yarn can fit into the groove on the outer periphery of the lens to hold the lens.

  The eyeglass frame according to the present invention has a configuration in which a part of the outer periphery of the lens is restrained by a high tension yarn. Moreover, when the lens is fitted, the lens can be fixed by screwing the broach connected to the high-tension thread. Therefore, when the lens is fitted to the rim, the lens surface is not scratched or the frame is not scratched as in the prior art, so that the lens can be easily attached and no special skill is required.

  In particular, in the case of a rim structure composed of upper and lower rim portions and high tension yarns stretched in the space between both rim portions, it is not easy to fit the lens by stretching the relatively short high tension yarns. In the case of the glasses frame of the present invention equipped with a broach, the lens can be easily attached by loosening the broach.

  FIG. 1 shows an embodiment of an eyeglass frame according to the present invention. The front part 1 has half rims 2 and 2 having a substantially semicircular arc connected by a connecting member 3, and water threads 4 and 4 are stretched below the half rims 2 and 2. That is, the half-rim type eyeglass frame shown in FIG. Therefore, the lens 5 is restrained by the half rim 2 and the water thread 4, and the water thread 4 is fitted in a groove provided along the outer periphery of the lens and is urged by a predetermined tension. Here, in the eyeglass frame of the same figure, the half rims 2 and 2 are located above the lens 5 and the water thread 4 is located below the lens 5.

  By the way, the outer rims 2 and 2 are brazed on the outer side of the half rims 2 and 2, and are attached to the outer rims 6 and 6 via hinges 7 and 7 so that the cranes 8 and 8 can be folded. In the conventional half rim type eyeglass frame, both ends of the water thread 4 are connected and fixed to both ends of the half rim 2 as shown in FIG. 8, and the lens 5 is fitted by stretching the water thread 4. However, in the present invention, the base end of the water thread 4 is fixed at the half rim end portion on the connecting member side, but the broach 9 is connected to the end on the end side. Of course, it is also possible to provide the broach 9 on the connecting member side.

  The broach 9 is screwed to a broach 10 brazed to the half rim 2. Therefore, when the lens 5 is fitted, it is performed in a state where the screw of the broach 9 is loosened. FIG. 2 is an enlarged view showing the outer portion of the eyeglass frame shown in FIG. 1, and the broach 9 has one or two small holes 10, 10 penetrating therethrough. The thread 4 is inserted and fixed.

  Therefore, if the screw 11 of the broach 9 is loosened, the water thread 4 is also loosened and the lens 5 can be easily fitted. If the screw 11 is tightened when the water thread 4 is fitted in the groove on the outer periphery of the lens, the water thread 4 is pulled and the lens 5 can be fixed to the half rim 2. Therefore, when the lens 5 is fitted, the water thread 4 is not pulled and the lens surface is not scratched. Of course, no skill is required for the operation of fitting the lens 4.

  FIG. 3 shows another embodiment of the eyeglass frame according to the present invention. Unlike the case of the above embodiment, the eyeglass frame is provided with an upper rim portion 12 and a lower rim portion 13 on the front portion 1, and the lens 5 is sandwiched between the upper rim portion 12 and the lower rim portion 13. The central portion of the front portion 1 has a space 14 in which the lens 5 is not restrained, and a water string 4 is stretched in this portion to hold the lens 5. That is, the distance between the upper and lower rim portions 12 and 13 is increased to prevent the lens 5 from being detached.

  FIG. 4 shows a partially enlarged view of the front portion 1. Both ends of the water thread 4 are fixed to the upper rim portion 12 and the lower rim portion 13, and the lens 5 is pulled by being fitted to the outer periphery of the lens 5. It is locked in the groove. Also in this case, one or two small holes 10, 10... Pass through the upper rim portion 12 and the lower rim portion 13, and the water thread 4 is inserted and fixed in these holes 10, 10. Yes. A broach (not shown) is provided at the outer front end of the lower rim portion 13. The broach is pulled toward the upper rim portion 12 by tightening the screw 11, and the water thread 4 is also pulled to restrain the lens 5. To do.

  FIG. 5 shows still another embodiment of the present invention. The front part 1 of the eyeglass frame also has an upper rim part 15 and a lower rim part 16, and a space 14 is formed between the rim parts 15 and 16, and the outer periphery of the lens is not constrained in this part. Accordingly, the water yarn 4 is stretched in this space portion, and both ends of the water yarn 4 are fixed to the upper rim portion 15 and the lower rim portion 16.

  FIG. 6 is a partially enlarged view of the front portion 1 of the eyeglass frame shown in FIG. 5, and a water thread 4 is stretched around the outer periphery of the lens in the space portion. The water thread 4 is inserted and fixed in small holes 10, 10... Provided in the upper rim portion 15 and the lower rim portion 16. A broach 17 is provided at the tip of the lower rim portion 16, and the broach 17 is screwed to a broach 18 provided at the tip of the upper rim portion 15. Of course, the position of the broach 18 is provided at an appropriate position in consideration of the design of the eyeglass frame, and is not limited to the case shown in FIG.

  Therefore, if the screw of the broach 17 is loosened, the water thread 4 can be loosened and the lens 5 can be fitted. If the broach 17 is screwed when the lens 5 is fitted, the water thread 4 is pulled and is inserted into the outer circumferential groove of the lens. fit.
