BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose pad of an eyeglass frame.

[0002]

2. Description of the Related Art Glasses can function by being worn on the face. When the glasses are worn on the face, the glasses are supported by the ears and nose by two vines and both nose pads. Recent spectacle frames are made of light materials such as titanium, and the lenses are coated with plastic, which is lighter than glass lenses, but the weight of the spectacles is unevenly distributed on the front frame part. Sometimes, even with such lightweight glasses, if you wear them for a long time, you will feel pain on both sides of your nose.

Further, even with light glasses, the same phenomenon of slipping down occurs, and if the glasses slip down to any extent, the vine will be pulled and the ears will be hurt. Further slipping causes the focus of the lens to shift, which makes it difficult to see and at the same time reduces the visual acuity. The nose pad is pivotally supported by screws on a box brazed to a metal fitting extending from a part of the rim, and the nose pad has a certain degree of freedom. It is given swinging movement as an axis and movement by enlarging the screw holes so that it fits to each nose to some extent.

However, for a person with a very different nose shape, the movement of the conventional nose pad may not fit, and therefore the metal fittings are bent for adjustment.
It is not possible to completely prevent the misalignment of the glasses by just fitting the nose pads to both sides of the nose. For example, when performing a work of vigorously moving the body, particularly when performing an exercise, the nose pad is lifted and separated from the nose, and the position is easily displaced.

[0005]

[Problems to be Solved by the Invention] As described above, the conventional nose pad has the above problems. The problems to be solved by the present invention are these problems, and provide a nose pad that fits exactly to a nose of any shape and does not slip off from the nose even if the body is moved and is not displaced. .

[0006]

The nose pad according to the present invention has the following features. The nose pad is composed of a pad that directly contacts the nose and a fitting that holds the pad, and the fitting is connected to a metal fitting extending from the front frame. Here, the pad has a cavity inside, a plurality of small holes are formed on the contact surface (surface) with the skin, and a relatively large opening is formed on the back side. A spring-like wire is bent and built in the cavity, and the joint tool brazed to the wire end projects from the opening. Further, another opening is formed at one corner of the back surface.

[0007]

[Function] The wire accommodated in the pad is spring-deformed by the force acting on the joint. This wire is a thin wire that is built into the cavity of the pad without rattling, and when wearing glasses, the pressure acting on the skin-contacting surface (surface) of the pad deforms the wire and causes the above pressure when moving the body. If the wire falls and lifts from the nose, the wire acts to restore and keep the pad away from the nose.

Further, the spring force of the wire acts as a force for pushing up the front frame portion of the spectacles, and when the spectacles are worn, the weight of the spectacles is felt light and fatigue is reduced. On the other hand, small holes on the surface bite into the skin, albeit slightly, to prevent slippage. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 3 shows one form of a general eyeglass frame, in which a rim 3, 3 for holding and fixing a lens 2 is symmetrically brazed via a connecting plate 4 to a front frame 1.
Yoroi 5, 5 are fixed to both sides, and nose pads 6, 6 are attached below the connecting plate 4. And the crane 7 has hinges 8 on the armor 5
It is connected via the.

The details of the nose pad 6 according to the present invention are shown in FIGS. 1 and 2. 9 is a pad, 10 is a fitting, 11 is a wire, and the pad 9
Has a cavity 12 inside, and the surface (skin contact surface) 13 has a smooth convex curved surface. As shown in FIG. 2, a plurality of small holes 14, 14, ... Are bored in the front surface 13, and an opening 16 is formed in the back surface 15 at substantially the center and another opening 17 is formed in one corner. And the cavity 1
The wire 11 is accommodated in the wire 2, and the joint tool 10 brazed to the wire 11 projects from the opening 16 to the back surface 15 side. The fitting 10 is fixed to a metal fitting extending from the front frame 1.

Here, the wire 11 is a thin wire material rich in spring property, and one continuous wire 11 is curved into a three-dimensional shape and is housed in the cavity 12 without rattling. Of course, the pad 9 is formed separately from the front surface 13 and the back surface 15, and the front surface 13 and the back surface 15 are joined and integrated with the wire 11 accommodated. The wire 11 is curved into a three-dimensional shape, and the wire 11 can be deformed when pressure (P) acts on the fitting 10.

That is, this pressure (P) is a force that supports the front frame portion when wearing glasses, and even if the pressure (P) changes with the movement of the body, the wire 11 will change in accordance with the change. The amount of deformation increases and decreases, and the surface 13 acts so as not to separate from the nose. Also, the small holes 1 on the surface 13
4 and 14 bite slightly into the skin to prevent the pad 9 from slipping, and each of these holes 14, 14 ... Is an area where the skin comes into contact with air. That is, if the holes 14, 14, ... Are not present, the entire surface 13 is in contact with the skin, and the skin in that portion blocks air, discolors the skin red, and causes pain, but these holes 14, 14 ... It has a function to eliminate the phenomenon.

On the other hand, another opening 17 formed on the back surface 15 is a hole for removing dust adhering to the inside of the cavity 12 together with water, and can be easily cleaned. As described above, the spectacle frame nose pad of the present invention hollows out the pad to form a large number of small holes on the surface thereof, and the three-dimensionally curved wire is housed in the hollow, and the wire is brazed to the wire. Since the attached fitting is projected from the opening on the back surface, the following effects can be obtained.

[0014]

Since the pad of the present invention accommodates the wire in its cavity, the direction and position of the pad can be freely changed within a certain range by the deformation of the wire, and it can be perfectly fitted to any nose. . The wire can be deformed by a force acting between the wire and the nose, and the wire does not deform even if the body is moved so that the pad does not separate from the nose. Therefore, the glasses do not slip off or shift the position. .

Furthermore, the small holes formed on the surface slightly bite into the skin to prevent the pad from slipping and reduce the area where the pad blocks the air, thereby eliminating discoloration or pain of the skin. You can on the other hand,
The wire is in a state of being slightly deformed due to its weight when wearing glasses, and the restoring force of the wire not only prevents displacement of the glasses as described above, but also reduces the weight of the glasses and relieves fatigue. You can
