Description

[0001]
[Industrial applications]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose pad used for eyeglasses, sports glasses, dustproof eyeglasses, and other various kinds of eyeglasses which are used in daily life.
[0002]
[Prior art]
Heretofore, there is an eyeglass nose pad of this type in which a plurality of lateral grooves are provided on the surface of the pad.
[0003]
The multiple lateral grooves provided on the surface of this pad increase the frictional force with the contact part of the nose, to prevent the pad from sliding with sweat, such as when sweating the nose, and to prevent the glasses from slipping It is provided.
[0004]
Further, there is an eyeglass nose pad of this type that uses sponge rubber as a material of the pad in order to adapt to a contact portion of a user's nose.
[0005]
[Problems to be solved by the invention]
However, in the above-mentioned conventional nose pad for spectacles, the plurality of lateral grooves provided on the surface of the pad are not considered for compatibility with the contact portion of the nose, and the compatibility is not improved at all. Therefore, even if the eyeglasses do not shift, there is a problem that it is not possible to solve the problems such as leaving a mark of the pad clearly on the contact portion of the nose and causing the pain of the contact portion of the nose. .
[0006]
Further, in the above conventional nose pad for spectacles, in the case of using sponge rubber, the sponge rubber is too soft as a material of the pad, so it has to be thickened and not only bulky, but also the design of the pad Had the problem of being restricted to.
[0007]
Therefore, the present invention is to solve the problems of the above conventional nose pad for eyeglasses, and to provide a nose pad for eyeglasses without increasing the bulk and without being restricted by the design of the pad. It was done.
[0008]
[Means for Solving the Problems]
Therefore, the nose pad for spectacles of the present invention is provided with a plurality of vertical grooves 2a on the surface of the pad 2 made of an elastomer so as not to reach the peripheral edge of the pad 2, and the pad 2 is easily bent vertically. The pad 2 conforms to the shape of the contact portion of the nose and conforms to the contact portion.
[0009]
Further, in the eyeglass nose pad of the present invention, the vertical groove 2a can be formed into a curved shape or a zigzag shape.

[0010]
[Action]
In the nose pad for spectacles of the present invention, the pad 2 is made of an elastomer, and the plurality of vertical grooves 2a provided on the surface of the pad 2 makes the pad 2 easily bend vertically. It follows the shape of the part and fits the contact.
[0011]
Further, the vertical groove 2a is provided on the inner surface of the pad 2 and is formed into a curved shape or a zigzag shape, so that the frictional force with the contact portion of the nose is increased, and even when the nose is sweated, The pad does not slip and the glasses do not slip.
[0012]
【Example】
Hereinafter, the configuration of the nose pad for glasses according to the present invention will be described with reference to the drawings shown as examples.
[0013]
FIG. 1 shows eyeglasses 1 to which a nose pad for eyeglasses of the present invention is attached and which is generally used everyday. The spectacle nose pad of the present invention has a plurality of longitudinal grooves 2a provided on the surface of a pad 2 made of an elastomer. For example, a projection (not shown) provided at a nose pad attachment position of the spectacle frame 3 is attached. At the same time as fitting into the fitting holes 4 provided in the surface 2b, the mounting surface 2b is bonded to the nose pad mounting position of the spectacle frame 3 with an adhesive.
[0014]
Examples of the elastomer include natural rubber, various synthetic rubbers, recycled rubber, and acrylic resin. However, the type of the elastomer is not particularly limited, and a styrene elastomer is used in Examples.
[0015]
The plurality of vertical grooves 2a provided on the surface of the pad 2 are inner surfaces in the embodiment, but may be outer surfaces. Further, as shown in FIGS. 2 and 3, the vertical groove 2a has a linear shape and a depth of about half the thickness of the pad 2, and can extend over substantially the entire area. In this embodiment, the vertical groove 2a has a linear shape, but may have a curved shape or a zigzag shape. Further, in the embodiment, the cross-sectional shape of the vertical groove 2a is substantially U-shaped, but may be various shapes such as substantially V-shaped and substantially U-shaped.
[0016]
FIG. 4 shows sports glasses 1 to which a spectacle nose pad of the present invention is attached, and uses a single-lens lens 5. An inverted V-shaped lens holder 6 to which a pad 2 having the same configuration as that of the above-described embodiment is attached is fitted into a portion of the single-lens lens 5 cut out in a nose shape.
[0017]
The pad 2 attached to the lens holder 6 is formed as a single body in the right and left in the embodiment, but it is needless to say that the left and right may be formed as separate bodies.
[0018]
Therefore, when the spectacles with the spectacle nose pad of the present invention configured as described above are used, the pad 2 easily bends vertically, so that the pad 2 conforms to the shape of the contact portion of the nose, and the pad 2 is shown in FIG. The state shown in FIG. 5 changes from the state shown in FIG. 5 to the state shown in FIG.
[0019]
Further, in the case where the vertical groove 2a has a curved shape or a zigzag shape, the frictional force with the contact portion of the nose increases, and even when the nose is sweated, the pad does not slip and the glasses are worn. It does not shift.
[0020]
【The invention's effect】
The spectacle nose pad of the present invention is configured as described above, and can be made thinner than a conventional one that is devised to adapt to the user's nose contact portion. The bulk was not increased, and the design of the pad was not restricted.
[Brief description of the drawings]
FIG. 1 is a perspective view of eyeglasses to which a nose pad for eyeglasses of the present invention is attached and which is generally used every day.
FIG. 2 is a surface view of the spectacle nose pad of the present invention.
FIG. 3 is a sectional view of the nose pad for glasses according to the present invention, taken along line AA in FIG. 2;
