Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for mounting a nose pad of a metal spectacle frame.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional general metal eyeglass frame. As is well known, the eyeglass frame is composed of a front part (a) and a vine (b), (b), and the front part (a)
Connect the two rims (C) and (C) with the connecting member (D), and
(C), (C) braided outside (Y), (H),
The vines (b) and (b) are foldably attached to the yoro (c) and (c) via hinges (f) and (f). Also, the connecting member (d) inside the rim (c), (c)
At the lower side, nose pads (g) and (g) for supporting the front part (a) against the nose are attached.

The nose pad (g) has a leg (h) brazed to a rim (c) and a box is attached to the tip of the curved leg (h) as shown in detail in FIG. (Not shown) is attached, and a nose pad (g) is attached to this box. In this case, the fastening piece protruding from the back side of the nose pad (g) fits into the box and has some backlash, and the nose pad (g) can change its direction within a predetermined range. I can do it.

As described above, in order to attach the nose pad (g), the leg (h) must be brazed, and in a glasses retail store, the leg (h) is bent and the nose pad (b) is bent. (G) must be adjusted so that it touches the nose. At this time, the brazed leg (j) often comes off. Also, in the case of titanium frames that have been widely used in recent years, direct brazing may not be possible, so secondary processing such as surface treatment is required, and various methods are required for brazing the legs (h). The process is costly.

[0005]

As described above, the mounting of the nose pad for supporting the front portion has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a mounting structure for a nose pad that fixes the legs by screws.

[0006]

A nose pad according to the present invention is attached by screws without brazing its legs to a front portion. However, instead of being screwed to the rim or the connecting member, the structure is such that the screw is fixed by using a broach. That is, a broach that fits and tightens a lens on the rim is provided inside the rim (on the side of the connecting member), and the leg ends are sandwiched between the broach pieces and screwed.

[0007] The broach piece is brazed to the cut end of the rim, and it is tightened so that the lens fitted to the rim does not come off. However, the joint surface has an inclined surface so that it can engage with each other. It is made. Therefore, if the leg end is sandwiched between the broach pieces, there is a gap between the joining surfaces and it is impossible to mesh with each other. I have to. Here, the specific form of the nose pad is not particularly limited, and may have any leg shape. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

[0008]

FIG. 1 is an embodiment showing a mounting structure of a nose pad according to the present invention, and shows a back side of a front portion. In the figure, 1 is a nose pad, 2 is a leg, 3 is a rim, 4 is a broach, and 5 is a connecting member. Although the basic structure of the eyeglass frame is the same as that shown in FIG. 4, the eyeglass frame of the present invention is provided with a broach 4 serving as a cutout for fitting a lens on the connecting member side of the rim 3.

The broach 4 has an upper broach piece 6 and a lower broach piece 7, and one of the broach pieces is
And the other broach piece is engaged with each other by being tightened with a screw. The end of leg 2 is an upper broach piece
The box is attached to the tip of the leg as before, and the fastening piece that projects to the back of the nose pad is connected to the box. I have. The nose pad 1 can swing up, down, left, and right within a predetermined range, and can fit the nose when wearing glasses.

FIG. 2 is a development view of the broach 4. The upper broach piece 6 is brazed to the upper cut end of the rim 3,
The lower broach piece 7 is brazed to the lower cut end of the rim 3. The joining surface of the upper broaching piece 6 is concave on both slopes 8 and 8, and the joining surface of the lower broaching piece 7 is convex on both slopes 9 and 9 so that they do not shift by engaging with each other. .

About half of the joining surface of the upper broaching piece 6 is cut out to form a notch portion 10, and similarly, about half of the joining surface of the lower broaching piece 7 is also provided with a notch portion 11. A hole 12 penetrates the upper broaching piece 6 and a screw hole 13 is provided in the lower broaching piece 7. Also, reference numeral 14 in the drawing denotes a fastening portion formed at the end of the leg 2, and the fastening portion 14 compresses the end of the leg 2 into a plate shape and penetrates the hole 15 at the center. .

Therefore, the fastening portion 14 is provided with the upper broaching piece 6.
And the notch 10, which is sandwiched between
The screw 16 is inserted into the holes 12 and 15 and screwed into the screw hole 13 in this state. The upper broaching piece 6 and the lower broaching piece 7 are engaged with the slopes 8 and 9 and the slopes 9 and 9 in close proximity to each other, and the cut end of the rim 3 is connected via the upper and lower broaching pieces 6 and 7.

Here, since the heights of the notches 10 and 11 are slightly smaller than the thickness of the fastening portion 14, the two inclined surfaces 8, 8 and 9, 9 do not contact each other. And
The fastening portion 14 of the leg 2 is stably fixed. Conversely, by making the heights of the notch portions 10 and 11 slightly larger than the thickness of the fastening portion 14, the fastening portion 14 sandwiched between the upper and lower broach pieces 6 and 7 can play in the range of the gap. And as a result,
Gives freedom to the direction of the nose pad and allows it to fit into the nose.

Although the nose pad 1 shown in FIG. 1 is attached to the tip of the leg via a box, the present invention is not limited to the form shown in FIG. FIG. 3 (a) shows a leg and a nose pad that are integrally formed using resin.
The fastening portion 14 is integrated with the end of the leg, and penetrates the center through a hole 15 through which a screw is inserted. In such an integrated nose pad, the height of the notches 10 and 11 is increased and the upper and lower broaches 6 and 7 are sandwiched between the upper and lower broaches 6 and 7 so that the nose fits slightly.

FIG. 3B shows a case in which the nose pad 1, the leg 2, and the fastening portion 14 are integrated by using a metal plate. It is a relatively thin plate material that is stamped into a predetermined shape and torsionally deformed. In this case, a soft silicone resin layer may be formed on the surface of the nose pad 1 to improve the feeling of contact when hitting the nose. And legs 2 made of thin plate
Can flex and deform, so it can fit into the nose.

As described above, in the mounting structure of the nose pad according to the present invention, the broach is provided on the rim connecting member side,
The leg end is sandwiched and fixed to the broach, and the following effects can be obtained.

[0017]

According to the nose pad of the present invention, the end of the leg is screwed to a broach provided inside the rim.
Therefore, the legs do not come off because they are not brazed as in the prior art, and even a titanium frame that cannot be directly brazed can be easily attached using a broach. The joint surface between the upper and lower broach pieces is cut out to form a notch, and the fastening part provided at the leg end is fitted into this notch and screwed, so that the nose pad is more stable And mounted.

On the other hand, since the nose pad of the present invention can be attached by screws, it can be replaced with another nose pad. On the other hand, by increasing the height of the notch formed on the upper and lower broach pieces, it is possible to have a play on the fastening part sandwiched, especially in the nose pad integrated with the legs using resin. Are suitable.
