JP7226800B2 - thin glasses - Google Patents

Description

The present invention relates to thin spectacles as thin as a piece of paper that can be put in a book or a magazine as well as stored in a breast pocket when the spectacles are removed from the face and carried around.

Glasses come in a variety of forms and have a wide variety of designs and decorations. In terms of functionality, materials such as titanium are used to make it lighter so that you won't feel tired even if you wear it for a long time. Moreover, rimless spectacles are often used, in which both lenses are directly screwed with a connecting member without having a rim on the front portion, and an end piece is screwed on the outside of the lenses.

FIG. 4 shows general eyeglasses, and the eyeglasses are attached to both sides of the front part (A) so that the temples (B) and (B) can be folded. The front part (A) connects both rims (C) and (C) with a connecting member (D), and on the outside of both rims (C) and (C) there are attachments (E) and (E). It is brazed, and the vines (b) and (b) are connected to the end pieces (e) and (e) via hinges (f) and (f) so that they can be folded. Lenses (g) and (g) are fitted to the rims (c) and (c).

FIG. 5 shows a case where the eyeglasses are removed and the temples (B) and (B) are folded, and both the temples (B) and (B) overlap each other. As is clear from the figure, the temples (B) and (B) are folded behind the front part (A), and the thickness dimension H becomes relatively large. If it is a pair of spectacles for myopia, I always wear it, but I usually carry reading glasses in a spectacle case because I wear them when I work or read newspapers and magazines.

Therefore, reading glasses to be carried should be as compact as possible. Although there is a limit to reducing the length and breadth of the front part because it is placed on the face, the spectacle case that accommodates the spectacle case can be made thinner by reducing the thickness dimension H in the folded state. However, conventional spectacles are provided with approximately L-shaped attachments (E) and (E) on both sides of the front portion, and temples (B) and (B) attached to the attachments (E) and (E) are There is a limit to the reduction in thickness because it is folded to overlap the back side of the front portion.

The "thin spectacles" according to Japanese Utility Model Laid-Open No. 1-64616 have pivot shafts vertically provided at the left and right ends of the upper edge of the front portion of the spectacle frame, and temples are pivotally supported by the pivot shafts. Therefore, the spectacles can be folded compactly, can be stored without taking up space, are convenient to carry, and are particularly effective for reading spectacles.

The ``foldable spectacles'' according to Japanese Utility Model Laid-Open No. 5-45635 become thin like a card when folded, and even when put in a pocket of a shirt or clothes, the pocket does not swell and can be stored in a thin space such as a wallet. These glasses are possible and convenient to carry.
Therefore, the thin plate-like front with the lens fitted therein is hinged at the center and foldable, and the temple is also foldable consisting of a front temple and a rear temple, and when the temple is folded, the rear temple becomes the upper end of the front. Get on the edge.

"Thin eyeglasses" according to Japanese Patent Application Laid-Open No. 2009-69356 provides a broach at a position where an inclined line inclined downward with respect to a horizontal base line extending from the center of an approximately elliptical rim intersects the rim, and a joint is attached to the broach. At the same time, the axis of the joint is parallel to the tangent line of the rim at the above position, and the temple attached to the joint rises along the rim in the folded state flush with the front part, and then straightens. The tip portion is extended and curved, and when the temple is opened, it is inclined outward. Further, the connecting member for connecting both rims is provided in the lower side of the rim in the form of a chevron.
"Thin eyeglasses" according to Japanese Utility Model Laid-Open No. 1-64616 "Foldable spectacles" according to Japanese Utility Model Laid-Open No. 5-45635 "Thin glasses" according to JP-A-2009-69356

As described above, there are various kinds of thin spectacles configured so that reading spectacles can be compactly carried. The problem to be solved by the present invention is that the temples have the same surface when folded without a joint such as a hinge, and the thickness is constant and extremely thin like a piece of paper, so that it can be put in a chest pocket or used as a seal To provide thin spectacles which can be carried between books and can be easily hung.

The thin spectacles according to the present invention are constructed using a plate material having a constant thickness, for example, a metal plate such as β titanium or a resin plate, and the front portion and both temples are formed in the same plane. The plate material is manufactured into a predetermined shape by laser processing, wire cutting, sometimes press punching, or the like.
The front part has a rim to which a lens is fitted, both rims are connected symmetrically via a connecting part, and a nose pad is provided below the connecting part. A connection part is formed on the outside of the front part, and a temple extends from the connection part to the center of the front part along the rim.

Both rims, both end pieces, both nose pads, and both temples formed on both sides of the connecting portion are formed on a single metal plate. Here, although the specific shapes of the rim, end piece, nose pad, and temple are not limited, laser processing, wire cutting, or the like is performed under the control of a programmed computer.
When wearing thin spectacles, temples formed on the same plane can be opened by turning (rotating) so as to extend rearward of the front portion. A plurality of slits are formed in the end pieces provided on both sides of the front portion, and the end pieces are torsionally deformed through the slits, and the temples can be turned and opened.

When the temples of the thin spectacles according to the present invention are folded, they fit on the same plane as the front part, so the thickness of the folded spectacles becomes thin like a piece of paper.
Moreover, the temple does not have a joint such as a hinge and is formed on the same plane as the front part, and its weight is very light, about 3 g. The temples can be opened and closed, but they are twisted through the slits provided in the end piece, which is the outside of the front part, and the temples turn open, and both temples extending backward are placed on both sides of the face. It can be hung by pinching. As soon as it is removed from the face, the temples turn and fit on the same plane as the front part.

The thin spectacles of the present invention are manufactured by cutting a single metal plate by laser processing, wire cutting, or the like, and the front portion and temples are formed on the same plane. That is, there are no brazed parts, and although the thickness is thin, it is strong. The temples can be swiveled through the slits formed in the end pieces, making the glasses fit soft and comfortable. In addition, when the glasses are worn, the temples are short and long enough not to touch the hair when the glasses are worn, so they can be effectively used in beauty salons.
