Description

  The present invention relates to a mounting structure for a nose pad for a plastic eyeglass frame.

  The glasses have a front part and a vine, and a lens is attached to the front part. There are various methods of attaching the lens, and the most basic and long-used method is to attach the lens to the rim constituting the front portion. There is also a method in which the rim is a half rim on the upper half, and the lens is held on the lower side with a high tension thread such as water thread. Furthermore, without using the rim, the left and right lenses are directly screwed with a connecting member, and the lens A lens mounting structure, which is also commonly used on the outside, is a structure in which an armor is screwed.

  By the way, the front part provided with the lens in this way is supported by the front of the face, and the vine extending backward from the armor is hung on the ear. In order to support the front part on the front of the face, a nose pad is attached to the center of the front part in a pair, and the nose pad puts on both sides of the nose to place the front part in a predetermined position. (Height) can be held.

  By the way, in the case of a metal eyeglass frame, the curved leg is brazed inside the rim to which the lens fits, and the fastening piece protruding from the back of the nose pad is screwed to the box brazed to the tip of the leg. Yes. In this case, the nasal pad can be fitted to both sides of the nose by changing its direction so that the nose pad can be adapted to the nose. Moreover, when purchasing glasses, the position of the nose pad is generally adjusted by appropriately bending the leg so as to fit the nose.

  On the other hand, in the case of a plastic eyeglass frame, a nose pad that is integrated with the front part is formed, and therefore, the position of the nose pad cannot be adjusted. Therefore, when wearing glasses, the height of the front part may not be determined. FIG. 6 shows a nose pad (a) formed on the inner side (center) of the rim of the front portion, and is thus molded as a part of the front portion.

  And the nose pad (a) molded as a part of the front part is hard and the feel of the nose is not preferable. That is, since there is no cushioning property, the front part supported by the nose feels heavy. In addition, when performing intense exercise, the front part is poorly settled and often misaligned.

  As described above, the conventional nose pad mounting structure has the above-described problems. The problems to be solved by the present invention are these problems, and provide a mounting structure for a nose pad that can be easily mounted on the front portion of a resin spectacle frame.

  In the nasal pad putting structure according to the present invention, the nasal pad is attached to a metal butterfly foot. The butterfly leg includes a fitting portion and a mounting portion, and the fitting portion has two legs with a slit groove formed between them. A claw is formed on the tip of the leg so as to face outward. Therefore, a fitting groove is provided in the front center portion, and the butterfly foot is attached by fitting the fitting portion in this fitting groove. In this case, the two legs are bent and deformed inward to fit into the fitting groove, The claw at the tip of the leg bites into the inner surface of the fitting groove and is fixed.

  The nose pad is made of resin and may be made of a soft material such as silicone resin, and is composed of a pad part and a leg part that hit the nose. The leg portion is fitted and attached to the attachment portion of the butterfly foot. Here, either the case where the leg portion is fitted in the hole provided on the attachment portion side of the butterfly or the case where the attachment portion is fitted in the hole formed on the leg portion side may be used.

  The attachment structure of the nose pad according to the present invention is configured by attaching a butterfly foot to the front portion and attaching the nose pad to the butterfly foot. The fitting portion provided on the butterfly leg is composed of two legs having a slit groove therebetween, and the leg is fixed by being fitted into the fitting groove of the front portion. In this case, by adjusting the depth at which the fitting portion fits into the fitting groove, the position of the nose pad that is attached to the butterfly foot is changed, and can be fitted to both sides of the nose. The nose pad has a pad part and a leg part, and the leg part can be fitted and attached to the attachment part of the butterfly foot, and the shape of the pad part can be variously changed.

  FIG. 1 is an external view showing a resin spectacle frame, in which 1 denotes a front portion, 2 denotes a temple, and 3 denotes a nose pad. The front part 1 is an integrally molded product having both rims 4 and 4 and a connecting part 5, and the temples 2 and 2 are attached to both side ends of the front part 1 so as to be foldable via joints. The tips of the temples 2 and 2 are curved so that they can be locked to the ears, and nose pads 3 and 3 are attached to the center of the front part 1 in pairs.

  By the way, the nose pad 3 is not integrally formed with the front portion 1, but a nose pad 3 as an independent part is attached. FIG. 2 shows an embodiment of a butterfly foot 6 to which the nose pad 3 is attached. The butterfly foot 6 is obtained by punching or cutting a metal plate (stainless steel plate, titanium plate, etc.) into a predetermined shape. The butterfly foot 6 has a fitting portion 7 and an attachment portion 8, and the fitting portion 7 and the attachment portion 8 are connected by a connecting portion 9.

  And the fitting part 7 has the two legs 10 and 10, the slit groove | channel 11 is formed between both the legs 10 and 10, and the nail | claws 12 and 12 are provided in the leg tip at the outward direction. Further, the mounting portion 8 has a substantially oval shape with a hole 13 in the center. The fitting portion 7 is fitted into a fitting groove provided in the front portion 1, and the nose pad 3 is attached to the hole 13 of the attachment portion 8.

  FIG. 3 shows a specific example of the nose pad 3, and the nose pad 3 is made of resin, for example, soft silicon resin can be used. The nose pad 3 is composed of a pad portion 14 and a leg portion 15 and is integrally formed. The surface 16 of the pad portion 14 forms a smooth convex surface, and has a shape that is greatly curved toward the inside (center side of the front portion).

  The leg portion 15 is attached by being fitted into the hole 13 of the attachment portion 8 of the butterfly foot 6, and therefore the leg cross section has the shape of the hole 13. A flange 17 having a large outer shape is provided at the tip of the leg portion 15 so as not to come out of the hole 13. By the way, when attaching the nose pad 3 to the attachment portion 8, the flange 17 is compressed and deformed, and the leg portion 15 is fitted into the hole 13.

  FIG. 4 shows a case in which the fitting part 7 is fitted into the fitting groove 18 provided in the front part 1 and the butterfly foot 6 is attached. Both the legs 10 and 10 of the fitting part 7 are deformed and pushed inward. (a) shows a case where the fitting portion 7 is pushed to the middle of the fitting groove 18, and (b) shows a case where the fitting portion 7 is pushed to the bottom of the fitting groove 18. The groove width of the fitting groove 18 is the plate thickness of the fitting portion 7, and the fitting portion 7 fitted as shown in (b) is stable without rattling.

  The fitting portion 7 fitted to a predetermined depth does not come off even if the claws 12, 12 at the tips of both legs bite into the inner side surfaces 19, 19 of the fitting groove 18. By the way, in general, the fitting portion 7 is attached by being pushed down to the bottom of the fitting groove 18, but it may be attached with a gap between the bottom and the bottom. If the fitting part 7 is pushed to the bottom of the fitting groove 18, the distance between the nose pads 3, 3 becomes large, and conversely, the fitting part 7 is pushed into the bottom of the fitting groove 18 leaving a gap. If so, the distance between the nose pads 3 and 3 becomes small.

  FIG. 5 shows a case where the nose pads 3, 3 are located on both sides of the nose 20, and the nose pads 3, 3 are arranged in accordance with the depth at which the fitting portion 7 is pushed into the fitting groove 18. Position adjustment becomes possible. That is, the nose pads 3 and 3 are adjusted according to the shape of the nose 20, and can be fitted to both sides of the nose.
