Description

  The present invention relates to a structure of a portion that comes into contact with the skin surface when wearing glasses, that is, a structure of a nose pad and a modern or crane tip.

  FIG. 6 is a specific example showing a general edgeless eyeglass frame. The rimless eyeglass frame does not have a rim on which the lens fits, and both lenses (A) and (B) are screwed to fastening pieces (C) and (C) extending to both sides of the connecting member (B). Fixing pieces (c) and (c) of screws (d) and (d) are screwed to the outside of the lenses (b) and (b). And the iron (d) and (d) are attached so that the crane (f) and (f) can be folded via a joint such as a hinge.

  A leg extends from the connecting member (b), and a nose pad (e), (e) is attached to the tip of the connecting member (b). Modern (g) and (g) are inserted. Therefore, when the glasses are put on the face, the front part supports the nose pads (e) and (e) against the nose, and the modern (g) and (g) are locked to the ear. The nose pads (e) and (e) are in contact with both sides of the nose, but are provided with a postcard so that its direction slightly changes according to the shape of the nose.

  However, the direction of the nose pad made of hard resin is slightly changed, and even if it contacts both sides of the nose, the entire surface does not contact uniformly, but only a part contacts. Even if the entire surface is in contact, the contact surface pressure is not uniform and locally exhibits a high surface pressure. This point also has the same problem in the case of a modern “finger” modern that is locked to the ear, and cannot be uniformly contacted along the base of the ear.

  Of course, a nose pad made of soft silicone resin is used in part, but this nose pad made of silicon is deformed as a whole and only part of it touches the skin. That is, it is soft and has good skin contact, and the contact area with both sides of the nose is increased, so that the surface pressure does not decrease. Therefore, a nose pad made of hard resin and a nose pad made of soft resin often feel pain when wearing glasses for a long time.

  In order to solve such problems, a structure in which air is filled in a nose pad is known. As a conventional example, for example, there is “a member for spectacles having an air cushion portion” according to registered utility model No. 3004316. This member for spectacles is intended for the modern that is inserted into the nose pad and the tip of the vine, but the entire abdominal part in contact with the skin is an air cushion part rich in soft elasticity that contains air.

Further, “Glasses nose pad” according to Japanese Utility Model Laid-Open No. 5-9187 is a nose pad that is filled with liquid instead of air. That is, the liquid is covered with a film on the plate with the metal fitting, and the liquid is contained in the film.
The “nose pad” according to registered utility model No. 3117777 is a nasal pad that is filled with various cushioning materials such as air and water, and is filled with a nasal pad member and a cushioning material that are connected to a frame of glasses, and the nasal pad member And a pad portion that is provided on the side surface and is in close contact with the back of the user's nose.
"Member for glasses having an air cushion" according to registered utility model No. 3004316 "Nosepiece for glasses" according to Japanese Utility Model Publication No. 5-9187 "Nose pad" related to registered utility model No. 3117777

  Since the nose pad that is filled with air or liquid can be deformed in conformity with the shape of the nose, the actual contact surface with the skin increases and the contact pressure decreases. Of course, the skin feel is good, and it is difficult to feel pain even when wearing glasses for a long time. However, it is not easy to manufacture a nose pad that is filled with air, and the cost is inevitably high. The conventional air-filled nose pad is limited to a metal eyeglass frame, and cannot be applied to a resin eyeglass frame.

  The problems to be solved by the present invention are these problems, and provide a nose pad that can be manufactured relatively easily at a low cost, can be produced in a variety of small lots, and can be applied to resin eyeglass frames. To do. On the other hand, the present invention is not limited to a nose pad but also covers a modern that is locked to the ear, and provides a modern that is provided with a pad filled with air on the side in contact with the skin and that is relatively inexpensive to manufacture.

  The structure of the contact portion with the skin in the glasses of the present invention is intended for the structure of the nose pad and the modern structure. Therefore, the side in contact with the skin has a pad structure filled with air, but in the present invention, a generally bowl-shaped pad is bonded to the base plate. The base plate may be provided at a leg tip extending from the front portion, or an existing nose pad made of hard resin may be used as the base plate. In particular, in the case of a resin eyeglass frame, a bowl-shaped pad is bonded to the surface of an existing nose pad part.

  On the other hand, in the case of modern, a long and narrow pad is bonded to the inner side in contact with the skin. The pad is also filled with air, and the pad is made of an elastic resin so that it can be deformed by pressing the pad surface. A rubber-based resin sheet may be attached to the pad surface for preventing slippage. Alternatively, rubber-based resin may be coated.

  The structure of the contact part with the skin according to the present invention is a nose pad and modern filled with air, can be deformed along the shape of the nose, and can be deformed along the base of the ear. Although this point is the same as the conventional air-filled nasal pad and modern, the present invention has a structure in which a generally bowl-shaped pad or an elongated pad is bonded to the base plate. Therefore, the manufacturing cost is low, and the pad can be attached to existing glasses. In particular, the mold for forming the pad may be the simplest. And it is applicable not only to a metal spectacle frame but also to a resin spectacle frame.

  FIG. 1 is an external view showing a nose pad 1 targeted by the present invention. As is well known, the nose pad 1 is attached to the tip of the leg 4 extending from the rim 3 on which the lens fits so that the front part 2 of the glasses can be supported on both sides of the nose. The front portion 2 shown in the figure is made of metal, both rims 3 and 3 are connected by a connecting member 5, and the legs 4 are brazed to the center side of the rim 3.

  The nose pad 1 includes a base plate 6 and a pad 7. The base plate 6 is attached to a box 8 at the end of the leg. A fastening piece 9 provided on the back surface is screwed in a state of being fitted in the box 8. Then, a generally bowl-shaped pad 7 is fixed to the base plate 6 with an adhesive. FIG. 2 is a cross-sectional view showing the nose pad 1. The pad 7 bonded to the surface of the base plate 6 is filled with the air 10, and the inner pressure P acts evenly on the inner surface of the pad 7 by the pressing force. To do.

  Here, the pad 7 is made of a soft and elastic resin such as silicon or elastomer. The pad 7 is placed on the base plate 6 and the edges are bonded and fixed. That is, an air-filled nose pad can be manufactured very easily. The pad 7 filled with the air 10 is compressed and deformed by the action of an external force, but the internal pressure P acts uniformly on the inner surface. Therefore, when abutting on the side of the nose when wearing glasses, the pad 7 is deformed according to the shape of the nose, but a uniform pressure is generated on the contact surface with the skin.

  In the present invention, a pad 7 formed in a bowl shape is bonded to the surface of the base plate 6 and is not a conventional structure in which an air is filled in an integrated nose pad, but its production is simple and cost-effective. Will be cheaper. And the metal mold | die which shape | molds the bowl-shaped pad 7 becomes the simplest structure.

  FIG. 3 is an external view showing the nose pad 10 of the resin eyeglass frame. In the case of a plastic eyeglass frame, the front part 11 is an integrally molded product in which both rims 12 and 12 are connected by a connecting part 13, and a pad 15 is attached to a base plate 14 provided in the center part of the front part 11. It is glued. The pad 15 is made of a soft and elastic resin such as silicon or elastomer as in the case of the above-described embodiment, and is placed on the base plate 14 and the edges are bonded and fixed. And it compresses and deforms by pressing the surface of the pad 15, and the internal pressure P acts on the inner surface.

  By the way, the base plate 6 to which the pad 7 is bonded and the surface of the base plate 14 to which the pad 15 is bonded are preferably flat surfaces. However, the base plates 6 and 14 may be existing nose pads. . That is, the pad 7 or the pad 15 can be bonded to the surface of the existing nose pad. FIG. 4 shows a case where a rubber-based resin sheet 16 is adhered to the surface of the pad 7 and has a structure that improves the anti-slip effect.

  On the other hand, in addition to the nose pad, the modern contact portion with the skin targeted by the present invention is locked to the ear when wearing glasses to prevent positional displacement of the glasses. FIG. 5A is a front view showing the modern 17, and FIG. 5B is an enlarged cross-sectional view taken along the line AA in FIG. The modern 17 has a generally “hem” shape, is inserted into the tip of a metal temple 18, and a core metal 19 that is a part of the temple 18 is press-fitted into the central axis of the modern 17.

  A pad 20 is bonded to the inside of the modern 17 as shown in FIG. The pad 20 has an elongated shape, is provided along the modern 17, and the inside is filled with the air 10. In the drawing, the inside of the modern 17 to which the pad 20 is bonded is a flat surface, but it may be a smooth convex surface as in the outside.

  Therefore, the pad 20 adhered to the inside of the modern 17 is in contact with the skin and partially deformed by wearing glasses. However, the surface pressure acting on the skin is always made uniform, and no contact pressure is locally generated as in the prior art. Moreover, the pad 20 made of a silicon soft resin also has a non-slip effect. In addition, the pad of the modern 17 and the nose pad can be replaced with a new pad by removing the adhesive by dissolving it.

The nose pad of the present invention attached to a metal eyeglass frame. The cross-sectional enlarged view of the nose pad of the present invention. The nose pad of the present invention attached to a resin spectacle frame When a rubber-based resin sheet is attached to the pad surface. The modern of the present invention. The external view of edgeless glasses provided with the conventional nose pad.
