BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to spectacles, and is particularly preferably implemented as sunglasses.

[0002]

2. Description of the Related Art In general, a nose pad of a conventional sunglass or the like is integrally formed with a spectacle frame using a synthetic resin or the like. However, such a nose patch lacks a shock absorbing power, and therefore, when a wearer receives an impact on the head during sports or the like, the nose is likely to be damaged near the nose.

Therefore, in recent years, a technique has been generally used in which a nose pad is formed separately from the spectacle frame with a material that is softer than the spectacle frame molding material and has a high shock absorbing property, and then attached to the spectacle frame by a method such as bonding. I have. Further, in such a separately formed nose pad, a pad that directly contacts the nose with a soft material having sufficient elasticity, and a holding member that couples and holds the spectacle frame and the pad with a material harder than the pad. It has been proposed to form members and use them in combination by means such as bonding or fitting. Such a nose pad is disclosed in U.S. Pat. No. 4,859,048 (Patent Aug. 22, 1989). Thereby, the pad having more elasticity improves the protection function near the nose. At the same time, there are sunglasses and the like in which the left and right lenses are integrally formed so that the field of view is not obstructed, but in the glasses having such a structure, the holding member is directly attached to the lower edge of the lens. The member made of the material also has the effect of protecting the lens.

[0004]

However, since a large impact is expected during sports or the like, a further improvement in the impact absorbing power is expected even in a nose pad using such a combination of a pad and a holding member. It is rare. Especially,
There is still a problem in the safety at the time of wearing because the elasticity of the pad is not sufficiently exerted against the impact from immediately before and from the rear, and the joint is separated and the nose pad is easily disassembled at the time of the impact.

[0005] An object of the present invention is to provide eyeglasses that can improve the shock absorbing power and have a nose pad that is not likely to be undesirably decomposed, so that the safety at the time of wearing can be further improved. is there.

[0006]

In order to achieve the above object, the present invention takes the following technical measures. That is,
In a pair of eyeglasses formed by combining a nose pad made of a soft elastic material and a holding member for attaching and holding the nose pad to a spectacle frame or a lens, the nose pad is formed separately from the spectacle frame and the lens. The nose pad is provided with a concave portion, and the holding member is provided with a convex portion that fits with the concave portion, and the length of the concave portion in the fitting direction is larger than the length of the convex portion in the fitting direction. The eyeglasses are formed as described above.

A nose pad made of a soft elastic material and a holding member for attaching and holding the nose pad to an eyeglass frame or a lens are separate from the eyeglass frame and the lens. In the molded spectacles, the nose pad has a concave portion, and the holding member is provided with a convex portion that fits with the concave portion, and the width of the nose pad in the fitting direction and the vertical direction is, The eyeglasses are formed so that the width in the vicinity of the recess is stepwise larger than the width in the vicinity of the nose side.

[0008]

According to the present invention, the concave portion provided on the nose pad made of a soft elastic material and the projection provided on the holding member are fitted to each other, so that the nose pad and the holding member are joined. You. The length of the recess in the fitting direction is larger than the length of the protrusion in the fitting direction, so that a gap is formed in the recess in the fitted state. When the glasses receive an impact during sports or the like, the gap is compressed to absorb the impact.

Further, according to the present invention, the recess provided on the nose pad formed of a soft elastic material and the projection provided on the holding member are fitted to each other, so that the nose pad and the holding member are connected. Be combined. The width in the direction perpendicular to the fitting direction of the nose pad is formed such that the width in the vicinity of the concave portion is stepwise larger than the width in the vicinity of the nose side. In particular, at the time of an impact from immediately before, the nose pad is bent outwardly and spreads around the step portion as a fulcrum, and absorbs the impact without being separated from the holding member.

[0010]

FIG. 1 is a partially exploded perspective view of eyeglasses according to an embodiment of the present invention. A pair of spectacles 1, which are sunglasses used for sports or the like, includes a spectacle frame 2, a lens 3, and a nose pad 4. The spectacle frame 2 is formed of a hard synthetic resin or the like, and supports an upper edge of a lens 3 described later. The left and right binocular portions of the lens 3 are integrally formed, and an inverted V-shaped notch 7 is provided near the lower center thereof.

The nose pad 4 includes a nose pad 5 and a holding member 6.
And are fitted. The nose pad 4 is attached to the lens 3 by fitting a concave groove of a holding member 6 to be described later with a peripheral edge of the notch 7. First, the nose pad 5 will be described with reference to FIGS. FIG. 2A is a front view of the nose pad 5 viewed from the direction of arrow A in FIG.
(2) is a rear view thereof. FIG. 3 is an enlarged cross-sectional view taken along the line II in FIG. 2, and FIG. 4 is a line II in FIG.
It is the expanded sectional view seen from -II.

The nose pad 5 is made of a soft elastic material such as an elastic rubber containing an elastomer material. The shape of the nose pad 5 is generally an inverted V shape, and the center near the top is 5a, and the two legs symmetrical about the top are 5a.
5b, the leg portions 5b; 5b are formed to have a greater width in the direction of the arrow A (left-right direction in FIG. 3) than the central portion 5a.

A portion extending from the vicinity of the center of the leg 5b in the direction of the arrow A to the upstream end in the direction of the arrow A is referred to as a front portion 5F, and the portion extending from the vicinity of the center of the arrow A in the direction of the arrow to the downstream end thereof. Assuming the rear portion 5R, the width of the leg portion 5b in the direction perpendicular to the arrow A direction (the horizontal direction in FIG. 4) is such that the width W1 of the front portion 5F is more outward than the width W2 of the rear portion 5R. It is formed so as to bulge out by the width W3 and become larger stepwise. The front portion 5F is provided with a recess 8 that opens forward (upstream in the direction of arrow A). The length of the concave portion 8 in the vertical direction on the paper surface of FIG. 3 is d1, and the length of the concave portion 8 in the left-right direction on the paper surface of FIG. 3 is d2. A circumferential ridge 9 is formed at the opening of the recess 8 along the inner peripheral edge thereof.

The holding member 6 is made of, for example, a relatively hard synthetic resin material, and has a substantially inverted V-shape. The holding member 6 will be described with reference to FIGS. 5A is a front view of the holding member 6 as viewed from the direction of the arrow A, FIG. 5B is a rear view thereof, and FIG. 6 is a cross-sectional view as viewed from reference numeral III-III in FIG. ,
FIG. 7 is a cross-sectional view taken along the line IV-IV in FIG.

On the outer side of the holding member 6, a concave groove 11 is provided to fit into the notch 7 of the lens 3 as described above. In addition, 6a is a central portion near the top of the holding member 6,
Assuming that both legs are 6b; 6b, a projection 12 projecting downstream from the arrow A is provided at the downstream end of the arrow A of the leg 6b. A flange 13 protruding along the periphery is continuously provided at an end of the protrusion 12 opposite to the leg 6b. Assuming that the length of the protruding portion 12 including the flange portion in the vertical direction in FIG. (D1 ≒ d3). Further, the length d2 of the recess is formed to be larger than the length d4 of the protrusion (d2> d4). Assuming that the width of the leg 6b is W4, the width is substantially equal to the width W1 of the front portion 5F of the leg 5b of the nose pad 5 (W1 ≒ W4).

As shown in FIG. 1, the nose pad 5 and the holding member 6 are respectively provided in concave portions 8 provided on both legs 5b of the nose pad 5, and both legs 6b of the holding member 6; 6
The projections 12 provided on the b are connected to each other by fitting. At the time of fitting, the projecting portion 12 is strongly pressed against the opening of the recess 8, and the peripheral ridge 9 provided on the periphery of the opening of the recess 8 is pushed into the recess 8 while the projecting portion 1 is being pressed.
2 is inserted into the recess 8. The protruding portion 12 is pushed forward and further moved inwardly of the concave portion 8 so that the flange portion 13
When it advances to a position where it gets over, the circumferential ridge 9 returns to its original shape by its elastic force. Therefore, when the protruding portion 12 is moved to this position, the inner surface 9a of the peripheral ridge 9 and the inner surface 13a of the flange portion 13 are engaged to act as a stopper. Therefore, even if it receives an impact, there is little possibility that the nose pad 5 and the holding member 6 are decomposed. FIG. 3 shows this state, with the protrusion 12 as a two-dot chain line.

As described above, since the length d2 is formed to be larger than the length d4, the concave portion 8 in the fitted state.
A gap 14 is formed therein. Therefore, particularly when an impact is received from the front or rear direction, the gap 14 is compressed and absorbed. In addition, even in the case of impact from other directions, the nose pad 5 has much improved flexibility and is sufficiently bent to the outside of the nose as compared with the conventional solid nose pad, so that the impact can be reduced. It is possible to reliably escape to the outside.

As described above, since the width W1 of the front portion 5F of the leg 5b of the nose pad 5 and the width W4 of the holding member 6 are substantially equal, the fitting between the nose pad 5 and the holding member 6 is performed. In the state, the vicinity of the fitting portion is substantially flush. Also,
The width W2 of the rear portion 5R is wider than the width W1 of the front portion by W3.
However, the nose pad 4 is stepwise narrower in the nose direction than in the vicinity of the fitting portion. Therefore, especially for impacts from the front or back,
The nose pad 5 easily bends around the stepped portion as a fulcrum and spreads to the outside of the nose, so that the impact can be reliably released to the outside. At the same time, if there is no step, it is easy to bend the fitting part as a fulcrum, so that the fitting state is canceled and the nose pad 5 and the holding member 6 are likely to be undesirably disassembled. Since the impact can be released while the fitting state is maintained, the impact is reliably absorbed and the usability is remarkably improved.

It should be noted that the present invention is not limited to the above-described embodiment, and the details of the configuration can be appropriately changed in design.

[0020]

According to the present invention, a gap is formed in the concave portion when the nose pad and the holding member are fitted to each other. The shock is absorbed by being compressed. In particular, it is possible to reliably absorb the impact from the front or back side when the glasses are worn. In addition, this gap is easily deformed against impacts from other directions, so the nose pad has sufficient flexibility and bends easily to ensure that the impact escapes to the outside of the nose. Is possible. This allows
Dramatically improves safety when wearing glasses.

Further, according to the present invention, the width of the nose pad near the nose side is stepwise smaller than the width of the recess near the concave portion. It easily bends around the part and spreads outward from the nose. Therefore, it is possible to reliably release the impact to the outside of the nose, especially in response to the impact from the front or rear side. Also,
At this time, the nose pad and the holding member are not undesirably disassembled since the nose pad and the holding member are not bent around the fitting portion as a fulcrum as in the related art. Thereby, the usability of the glasses and the safety at the time of wearing the glasses are remarkably improved.
