Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to foldable eyeglasses.

[Prior art and its problems]

Since eyeglasses, especially reading glasses, are highly necessary to be portable, various types of foldable eyeglasses have been proposed and put into practical use. By the way, all conventional folding glasses are folded so that the front lenses are facing each other, and the temples are also folded in two accordingly.
It is foldable. In other words, "round"
Since it is foldable and has a short overall length, it is convenient to carry it in a small bag such as a bag. However, since it is thick when folded, there is a problem that the pocket will bulge if you put it in the pocket of a shirt or clothes. Furthermore, various types of cards are now in widespread use, and wallets, commuter pass holders, etc. have spaces for storing cards, but it is of course impossible to store folded glasses in such spaces.

[Purpose of invention]

Therefore, the present invention has been developed to create foldable glasses that fold into a card-like state, do not bulge even when placed in the pocket of a shirt or clothes, and can be stored in card storage spaces such as wallets and commuter pass holders. The purpose is to provide.

[Structure of the idea and its function]

The folding glasses of the present invention are foldable so that the thin plate-like front in which the lenses are fitted is divided into two parts in the center and the upper edges touch each other, and the temples consist of a hollow front temple and a rear temple. The temple is characterized in that the temple can be stored in a hollow part of the front temple, and the front temple can be stored in a bag part formed inside the front.

In other words, the front of the glasses is horizontally long and approximately rectangular, but the front of the present invention is thin and folds so that the upper edges touch each other, so the length of the front is halved and the width is doubled. become. Since the temple is housed in the front, the folded state is approximately the same as the shape of the card. Therefore, even if you put them in the pocket of a shirt or clothes, the pocket will not bulge out, and you can also store them in card storage spaces such as wallets and commuter pass holders, making them extremely convenient to carry. can.

〔Example〕

The present invention will be specifically described below based on embodiments shown in the drawings.

The front 1 has a substantially rectangular thin plate shape with a thickness of 3 mm, a length of 135 mm, and a width of 27 mm, into which a pair of lenses 2 for presbyopia are fitted, and a silicone pad 11 is fixed to the nose pad. This front 1
is divided into two parts at the center, and a second hinge 3 shown in FIG. 5 is fixed to the upper end of the divided part by a screw 31. are doing. Therefore, when this second hinge 3 is rotated, the upper edge 1a of the front 1
Comrades come into contact. Although FIG. 6 shows the second hinge 3 in an open state, there is a pair of magnets 3 inside the second hinge 3.
3 is fitted, and in the operating state shown in FIG. 1, the action of this magnet 33 prevents the second hinge 3 from rotating easily. The upper part of the front 1 is hollow, and as shown in FIG. 3, bag portions 12 having a predetermined length are formed from both ends. A flat first hinge 4 is provided at both ends of the front 1.
is attached to rotate freely, and the temple 5 is held by this first hinge 4 when in use, but this first hinge 4 also has a through hole 41 having the same shape as the bag portion 12 of the front 1. is formed. This temple 5 is composed of a front temple 6 and a rear temple 7. The linear front temple 6 is a rectangular cylindrical body made of titanium and has a hollow portion, and its outer dimensions are equal to the inner dimensions of the bag portion 12 and the through hole 41. The base end of the front temple 6 is slidably held in the through hole 41 of the first hinge 4, and when the front temple 6 is pulled out to the use position, a stopper pin is attached as shown in FIG. 41 is engaged with and positioned in the hole of the front temple 6. The rear temple 7 has an elongated plate shape made of a shape memory alloy, and has a silicon modulus 71 fixed to its rear end. And, it can be stored in the hollow part of the front temple 6. If it is stored in the hollow part of the linear front temple 6 for a long period of time, the rear temple 7
It also deforms into a straight line, but when in use, it returns to its memorized shape due to the body temperature of the head, and as shown in FIG. 2, it curves inward and comes into pressure contact with the head.

Therefore, when folding glasses with such a configuration, first, the rear temple 7 is housed in the hollow part of the front temple 6, and the first hinge 4 is placed on the same plane as the front 1, as shown in FIG. Rotate. As a result, the through hole 41 and the opening of the bag portion 12 coincide with each other, so that the front temple 6 in which the rear temple 7 is housed is pushed in and stored in the bag portion 12. When the storage is completed, the modern 71 is inserted into the notch 42 of the first hinge 4.
The rear end of the hinge 4 fits into the rear end of the first hinge 4 . When the front temples 6 on both sides are retracted, the second
The hinge 3 is rotated against the magnetic force of the magnet 33.
As a result, the upper ends 1a of the front 1 come into contact with each other, and the front 1 is folded into a card shape having a thickness of 3 mm, a length of 86 mm, and a width of 54 mm, as shown in FIG.
This size is approximately the same as various plastic cards, although the thickness is a little thicker. At this time,
Since the front temple 6 is inserted through both the through hole 41 and the bag portion 12, the first hinge 4 cannot rotate and the shape of the card is maintained. Therefore, it becomes possible to carry it in the same way as various plastic cards, and convenience is significantly improved.

Note that the folding order is not limited to the above-mentioned order, and may be folded in any order other than rotating the first hinge 4 so that it is flush with the front 1, pushing the front temple 6 in, and storing it in the bag portion 12. Good too. Then, when using the device, if the reverse operation is performed, the state shown in FIG. 1 will be obtained.

[Effect of idea]

As explained above, the foldable glasses of the present invention can be folded into a card shape, so even if you put them in the pocket of a dress shirt or clothes, the pocket will not bulge out, and it can be used for storing cards in wallets, commuter pass holders, etc. The foldable glasses can be stored in a small space and are extremely convenient.
