Abstract

PURPOSE: To obtain nose pads for spectacles which are less bulky and are not restricted in the design of the pads by providing the surfaces of the pads consisting of an elastomer with plural longitudinal grooves. CONSTITUTION: The pads are formed by providing the surfaces of the pads 2 consisting of the elastomer with the plural longitudinal grooves 2a. For example, the projections formed in the nose pad mounting position of a spectacle frame are fitted into fitting holes 4, 4 disposed on mounting surfaces 2b and simultaneously the mounting surfaces 2b are adhered to the nose pad mounting position of the spectacle frame by an adhesive. The pads 2 are liable to curve longitudinally if the spectacles mounted with the nose pads 2 for spectacles are used and, therefore, the pads 2 adapt themselves to the contact parts with the nose along the shapes of the contact parts with the nose. Further, the friction force with the contact parts of the nose increases by the pads formed to a curved shape or zigzag shape in the longitudinal grooves 2a. The pads 2 do not slip with the sweat and the spectacles stay put on the nose even if the nose sweats.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nose pad used for spectacles commonly used in everyday life, sports spectacles, dustproof spectacles, and various other spectacles.

[0002]

2. Description of the Related Art Conventionally, there is a spectacle nose pad of this type in which a plurality of lateral grooves are provided on the surface of the pad.

The plurality of lateral grooves formed on the surface of the pad are
It is provided to increase the frictional force with the contact part of the nose, to prevent the pad from slipping with sweat when the nose is sweating, and to prevent the glasses from slipping.

[0004] In addition, there is a nose pad for spectacles of this type in which sponge rubber is used as the material of the pad in order to fit the contact portion of the user's nose.

[0005]

However, in the above-mentioned conventional nasal pad for spectacles, the plurality of lateral grooves provided on the surface of the pad are not taken into consideration with respect to the compatibility with the contact portion of the nose, and the compatibility thereof is not considered. There hasn't been any improvement. Therefore, even if the glasses do not shift,
There is a problem that it is not possible to solve the problems such as leaving the mark of the pad clearly on the contact portion of the nose and causing pain on the contact portion of the nose.

In the conventional spectacle nose pad using sponge rubber, the sponge rubber is too soft as a material for the pad, so that the pad must be thick and bulky. The problem was that the pad design was also restricted.

Therefore, the present invention solves the problems of the above-mentioned conventional nasal pad for spectacles, and provides a nasal pad for spectacles which does not become bulky and whose design is not restricted. It was made to do.

[0008]

Therefore, in the nose pad for eyeglasses of the present invention, a plurality of vertical grooves 2a are provided on the surface of the pad 2 made of an elastomer.

Further, in the nose pad for spectacles of the present invention, the vertical groove 2a can be provided on the inner surface of the pad 2, and can be curved or zigzag.

[0010]

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 facilitates the pad 2 to bend vertically. It conforms to the shape of the contact part of the nose and conforms to the contact part.

Further, when the vertical groove 2a is provided on the inner surface of the pad 2 and is curved or zigzag, the frictional force with the contact portion of the nose is increased and when the nose is sweated. Also, the pads won't slip with sweat and the glasses won't shift.

[0012]

EXAMPLES Hereinafter, the constitution of the nose pad for spectacles of the present invention will be described.
An explanation will be given based on the drawings shown as examples.

FIG. 1 shows spectacles 1 for daily use, to which the nose pad for spectacles of the present invention is attached. In the nose pad for spectacles of the present invention, a plurality of vertical grooves 2a are provided on the surface of the pad 2 made of an elastomer. For example, a protrusion (not shown) provided at a nose pad attachment position of the spectacle frame 3 is attached to the nose pad. Simultaneously with fitting into the fitting holes 4 and 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.

Examples of the elastomer include natural rubber, various synthetic rubbers, reclaimed rubber, acrylic resin and the like. However, the type is not particularly limited, and a styrene elastomer is used in the examples. .

A plurality of vertical grooves 2 provided on the surface of the pad 2.
Although a is an inner surface in the embodiment, it may be an outer surface. Further, as shown in FIGS. 2 and 3, the vertical groove 2a has a linear shape and has a depth that is about half the thickness of the pad 2, and can extend over almost the entire area. Although the vertical groove 2a has a linear shape in this embodiment, it may have a curved shape or a zigzag shape. Further, in the embodiment, the vertical groove 2a has a substantially U-shaped cross section, but may have various shapes such as a substantially V shape and a substantially U shape.

FIG. 4 shows sports spectacles 1 to which the nose pad for spectacles of the present invention is attached.
Is assumed to have been used. And this single lens 5
The inverted V-shaped lens holder 6 to which the pad 2 having the same structure as that of the above-described embodiment is attached is fitted into the nose-shaped notch.

Although the pad 2 attached to the lens holder 6 is formed as one body on the left and right in the embodiment, it goes without saying that the left and right sides may be formed as separate bodies.

Therefore, when the spectacles having the nose pads for spectacles of the present invention configured as described above are used, the pad 2 easily bends vertically, so that the pad 2 can be shaped according to the shape of the contact portion of the nose. Changes from the state shown in FIG. 3 to the state shown in FIG. 5, which is suitable for the contact portion.

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 the pad does not slip even when sweating on the nose. , The glasses will not shift.

[0020]

EFFECT OF THE INVENTION The nose pad for spectacles of the present invention is constructed as described above, and is thinner than the conventional one which is devised so as to be adapted to the contact portion of the nose of the user. As a result, the volume is not increased and the pad design is not restricted.
