Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to simple dust-proof glasses for protecting the eyes from dust and the like.

[Conventional technology]

In machine factories, foundry factories, etc., dust-proof eyeglasses are used to protect the eyes when dust is liable to rise when using abrasive members for returning products or hand-finishing or for cleaning work.

The conventional dust-proof spectacles are composed of a frame portion made of thick-walled soft synthetic resin material and a see-through portion such as glass or synthetic resin formed separately from the frame portion, and do not mainly provide a bridge connecting the see-through portions. A single curved surface that covers both eyes is used as the see-through portion, and a peripheral edge portion of the see-through portion is formed so as to close the periphery of the eye. Then, fine ventilation holes are provided on the peripheral walls located above and below the eyes to prevent fogging.

[Problems to be solved by the device]

However, the above dust-proof glasses have a thickness of about 2 mm, and since the see-through portion has a large single curved surface, the weight increases and becomes considerably bulky. For this reason, when the above-mentioned work is performed using this, it is easy to feel a feeling of weight and pressure on the face, and particularly when performing continuous work for a long time, even if the ventilation hole is provided in the peripheral wall, There was a drawback in that sweat could get in your eyes and bother you just by preventing fogging. There has also been a demand for simple dust-proof eyeglasses for general households, which protects the eyes during a large cleaning or similar work.

It is an object of the present invention to provide a cheap and simple dustproof mirror by improving the above drawbacks.

[Means for Solving the Problems]

The dustproof spectacles are formed by integrally molding a transparent, thin plate-shaped hard synthetic resin material, and form a peripheral wall (2) so as to close the periphery of the eye from the peripheral portion of the see-through portion (1) (1). The bridge (3) that connects the transparent parts (1) bulges forward from the transparent part (1) in an inverted U-shape in section, and a score line (4) is inserted in the front-rear direction at the center of the upper part of the peripheral wall (2). The transparent portions (1) and (1) are allowed to rotate inward within a predetermined range about the bridge (3).

[Action]

When using the dust-proof glasses of the present invention, left and right slits (5) divided by a score line (4) provided at the center of the upper part of the peripheral wall (2)
The sliding parts (5) are vertically displaced from each other, and the transparent parts (1) and (1) are rotated inward about the bridge (3) as an axis. Then, the side edge portion (6) of the peripheral wall (2) can obtain a curved surface corresponding to a face shape having individual differences, so that it is possible to seal around the eyes.

〔Example〕

 The dustproof glasses of the present invention will be described with reference to the accompanying drawings.

An embodiment of the present invention is shown in FIGS.

The embodiment comprises a main body (7) of eyeglasses and rubber strings (8) hooked on both sides of the main body (7) and engaged with the head.

The main body (7) is integrally molded with a thin plate-shaped hard synthetic resin material such as polystyrene having a thickness of 0.5 mm, and as shown in FIGS. 1 and 2, the transparent portion (1) (1) A cylindrical peripheral wall that is concave in the upper and lower parts of the transparent portion (1) (1) and convex in the left and right sides of the transparent portion (1) (1) so as to close the periphery of the eye rearward from the peripheral portion. (2) is formed. A peripheral edge portion of the peripheral wall (2) is formed with a side edge portion (6) outward at a right angle to the peripheral wall (2).

The side edge portions (6) on both the left and right sides are provided with hooking portions (9) of rubber cords (8) that engage with the head. As shown in FIG.
The bridge (3) connecting the see-through parts (1) and (1) swells forward from the see-through part (1) in an inverted U-shaped cross section, and the bridge (3) is provided in the front-rear direction at the upper center of the peripheral wall (2). Score line (4)
Put in.

With this arrangement, the perspective parts (1) and (1) are moved about the bridge (3) while the slit parts (5) and (5) divided by the score line (4) are vertically slidably brought into sliding contact with each other. As indicated by the chain line in Fig. 3, the inner part rotates in a predetermined range. Thus, with this spectacle, the side edge (6) of the body (7) fits closely to the face and can seal around the eyes.

[Effect of device]

When the dustproof glasses of the present invention are put on, the body side edges of the glasses naturally and closely fit the face, and the effect is to close the eye area. In addition, this dustproof spectacles is formed by integrally molding a thin plate synthetic resin material, and the transparent portion side has a bridge with an inverted U-shaped cross section in front of the transparent portion at the center of a single plane. It can be manufactured at low cost, and because it is super lightweight, it has almost no feeling of weight and pressure on the face, and it has the effect that it is much harder to sweat than the conventional product, especially when performing continuous work for a long time.
