Description

The present invention relates to thin glasses that can be stored in a chest pocket or clipped into a book or magazine when carried around while being removed from the face.

Glasses come in many different shapes and sizes, with a wide variety of designs and decorations. And in terms of functionality, they are lightweight and made of materials such as titanium so that you don't feel tired even when wearing them for long periods of time.
Also widely used are rimless glasses that have no rim on the front, but instead have both lenses screwed directly to each other with connecting members and a frame screwed to the outside of the lenses.

Fig. 7 shows a typical pair of glasses, which has foldable temples (B), (B) attached to both sides of a front part (A). The front part (A) connects two rims (C), (C) with a connecting member (D), and end pieces (E), (E) are brazed to the outsides of the two rims (C), (C). The temples (B), (B) are foldably connected to the end pieces (E), (E) via hinges (F), (F).
Lenses (T) and (T) are fitted into the rims (Ha) and (Ha).

FIG. 8 shows a case where the glasses are removed and the temples (B) and (B) are folded, and both temples (B) and (B) overlap each other. As is clear from the figure, the temples (B) and (B) are folded on the back side of the front part (A), and the thickness dimension H thereof becomes relatively large.
Glasses for nearsightedness are worn at all times, but reading glasses are generally carried around in a glasses case to be worn when working or reading newspapers and magazines.

Therefore, it is necessary for the reading glasses to be as compact as possible.
Although there is a limit to reducing the vertical and horizontal dimensions of the front part because it is hung on the face, by reducing the thickness dimension H in the folded state, the glasses case to be accommodated becomes thinner.
However, in conventional glasses, roughly L-shaped endpieces (E) and (E) are provided on both sides of the front part, and temples (B) and (B) attached to the endpieces (E) and (E) are provided. Since it is folded so as to overlap the back side of the front part, there is a limit to the reduction in thickness.

Conventionally, various forms of thin glasses have been filed.
In the "thin glasses" disclosed in Japanese Utility Model Application Publication No. 1-64616, pivot shafts are provided vertically at the left and right ends of the upper edge of the front part of the glasses frame, and the temples are pivoted by the pivot shafts. Therefore, these glasses can be folded compactly, can be stored without taking up space, are convenient to carry, and are particularly effective as reading glasses.

In the "thin glasses" disclosed in JP-A-2009-69356, a brooch is provided at a position where an inclined line extending from the center of an approximately oval rim and extending downward from the horizontal baseline intersects the rim, and a joint is attached to the brooch. At the same time, the axis of the joint is parallel to the tangent to the rim at the above position, and the temple attached to the joint stands up along the rim flush with the front part in the folded state, and then straightens. The tip of the rim is extended and has a curved tip, and the temple is inclined outward when opened, and the connecting member connecting both rims is provided in the shape of a chevron on the underside of the rim.

The "thin glasses" of JP 2015-90390 A have a joint provided on the outside of the horizontal neutral axis of the front part, with the axis of the joint on one side inclined from the upper outside to the lower inside with respect to a plane including the front part, and the axis of the joint on the other side inclined from the upper inside to the lower outside with respect to a plane including the front part, and when the temples connected to these inclined axes are folded, the temple connected to the joint on one side is located above the front part, and the temple connected to the joint on the other side is located below the front part.
"Thin glasses" according to Japanese Utility Model Application Publication No. 1-64616 "Thin glasses" according to JP 2009-69356 A "Thin glasses" according to JP 2015-90390 A

There are many types of thin reading glasses that are designed to be compact and portable. In other words, when the temples are folded, the thickness becomes thin, so that they can be carried in a breast pocket or between the pages of a book.
However, because thin glasses are different in shape from regular glasses, putting them on and taking them off can be a hassle.
The problem to be solved by this invention is to provide thin glasses that allow the temples to be folded smoothly so that the operation of putting on and taking off the glasses is the same as that of regular glasses.

The thin glasses of the present invention are configured so that both temples can be folded toward the back side of the front part, and the temples can be folded in substantially the same plane as the front part. Therefore, fixed end pieces are provided on both sides of the front part, and a rotating end piece is rotatably attached to the fixed end pieces. The rotary endpiece can rotate about an axis extending outward from the fixed endpiece, and the temple turns vertically at the same time as the rotary endpiece rotates.
An arm extends from the rotating armoury, and the above-mentioned crane is connected to the tip of the arm via a joint so that it can be folded.

When wearing thin glasses, the arms and the temples extending from the arms fall down to a substantially horizontal state, and the tips of the temples are latched to the ears. Then, in this state, the vine is folded to the back side of the front part via the joint. In other words, the temples fold up in the same way as regular glasses.
On the other hand, if the rotating endpiece rotates and the arm can be directed towards the upper or lower side of the front part, and the crane is folded in this state, the crane will be placed along the upper or lower side of the front part. be done.

A positioning means is provided to position the rotating end piece when the arm and temple are horizontal and extend rearward from the front part, or when the arm and temple are extended upward or downward from the front part and are in the same plane. In other words, a stopper is provided to stop the rotating end piece at a predetermined position so that it does not rotate freely.
However, the present invention does not limit the specific structure by which the rotating end piece can rotate, the specific joint structure by which the temples can be folded, or the specific positioning means of the rotating end piece.

In the thin glasses according to the present invention, when the temples are folded, they fit on the same plane as the front part, so that the thickness of the folded glasses is thin. If the rotating endpiece is rotated and arranged so that the arm extends toward the rear of the front section, the temple can be folded toward the back side of the front section.
That is, since the thin glasses of the present invention can be folded by overlapping the back of the front part like regular glasses, they are easy to put on, and the operation of putting them on and taking them off is no different from that of regular glasses.

And if the temples are folded along the upper side of the front part, the glasses become thinner and the thickness of the glasses case also becomes thinner, so that not only can they be carried in a breast pocket, but they also function as a bookcase that can be tucked inside a book.
That is, when the user finishes reading, he or she can remove the thin glasses and tuck them in, and when the user starts reading again, he or she can put the thin glasses on as a sticker on his or her face.
When the temples are folded along the upper or lower side of the front part, they fit flush with the front part, so even if they are left on the floor, they will not be damaged if stepped on.

FIG. 2 is a plan view showing an embodiment of the thin glasses according to the present invention, in which the temples extend rearward. FIG. 3 is a front view of an embodiment of the thin glasses according to the present invention, in which the temples are folded on the back side. FIG. 3 is a side view of an embodiment of the thin glasses according to the present invention, in which the temples extend rearward. 1 is a plan view and a front view of an embodiment of a thin pair of glasses according to the present invention, in which the temples are folded above and below the front part. The rotating end piece attached to the fixed end piece rotates, causing the vine to fall down and the vine to stand up. A specific example showing a mechanism for positioning the rotation angle of a rotating endpiece. Traditional general glasses. When the temples of conventional glasses are folded.

1, 2, and 3 are examples showing thin glasses according to the present invention, in which FIG. 1 is a plan view, and FIG. 2 is a front view when the temples are folded to the back side of the front part. FIG. 3 shows a side view when the vine is extended. On both sides of the front part 1, temples 2, 2 are attached so as to be foldable.
In the front part 1, both rims 3, 3 into which lenses are fitted are connected by a connecting member 4 curved in a chevron shape, and fixed end pieces 5, 5 are provided on the outside of the rims, and rotary end pieces 5, 5 are provided on the outside of the rims. 6,6 are installed.
The cranes 2, 2 are foldably connected to the tips of arms extending from the rotary armouries 6, 6 via joints. Further, a pair of nose pads are attached to the center of the front part 1.

By the way, in the thin glasses of the present invention, as shown in the plan view of FIG. 1 and the side view of FIG. 3, both temples 2, 2 extend rearward from both sides of the front part 1. In this state, if both the temples 2, 2 are placed on the sides of the face and the moderns 8, 8 provided at the tips are secured to the ears, it can be worn on the face. Then, the temples 2, 2 are folded through the joints 9, 9 provided at the ends of the arms 7, 7, and as shown in FIG. Folded. That is, the folding operation of both temples 2, 2 is the same as in the case of general glasses.

FIGS. 4A and 4B show a case where both temples 2a and 2b are folded along the upper and lower sides of the front part 1. Both temples 2a and 2b are folded so as to fit within the same plane as the front part 1, and unlike the case where the glasses are folded to the back side of the front part 1 as shown in FIG. 2, the glasses in the folded state become thinner. .
When both temples 2a and 2b are folded along the upper and lower sides of the front part 1, this is also done via the joints 9a and 9b, but by rotating the rotating end pieces 6a and 6b by approximately 90 degrees, the joints are folded. 9a can face upward, and joint 9b can face downward.

As described above, in the thin glasses of the present invention, the rotating armours 6, 6 are attached to the fixed armours 5, 5 provided on both sides of the front part 1, and the direction of the arms 7, 7 can be changed by rotating the rotary armours 6, 6. can be changed, and the positions of both temples 2a, 2b attached to the ends of the arms 7, 7 via joints 9, 9 can be changed.
Therefore, both temples 2, 2 can be folded on the back side of the front part 1, as shown in FIG. 2, and both temples 2a, 2b can be folded, as shown in FIG. The front part 1 can also be folded along the upper and lower sides.

FIG. 5 shows the rotational movement of the arm 7, the joint 9, and the crane 2, which rotate together with the rotation of the rotary armoury. When the glasses are worn, the temples 2 are in a nearly horizontal state and extend toward the rear of the front section 1, as shown in (a), so that the glasses can be removed and folded toward the back side of the front section 1. .
Then, as shown in (b), if the rotary endpiece 6 is turned to raise the arm 7 upward and the arm 7 is folded in this state, the temple 2 will be arranged along the upper side of the front part 1.
Of course, if the rotating armoury 6 is rotated in the opposite direction so that the arm 7 is directed downward, the temple 2 will be placed along the lower side of the front section 1.

By the way, although the rotating armoury 6 rotates around the shaft 10, the temple 2 must be positioned. That is, when the temple 2 is in a horizontal state and can be folded toward the back side of the front section 1 as shown in (a), or when the temple 2 is folded above the front section 1 as shown in (b). It can be folded and is located on the same plane as the front part 1. In each of these cases, the rotary armoury 6 is rotated to position it at a predetermined position.

FIG. 6 shows a specific example of a mechanism for positioning the rotation angle of the rotating armoury. The rotary armor 6 is attached to the fixed armor 5 via a shaft 10, and the shaft 10 is fixed by a fixing pin 11 so as not to come off. The shaft 10 has a collar 12 with a large outer diameter, and the rotating armoury 6 has a space 14 with a large inner diameter, and a coil spring 13 is accommodated in this space 14. Due to the spring force of the coil spring 13 trying to expand, the rotating armoury 6 is pressed in the direction of the arrow shown in the figure, and the abutment surface 15 at the tip abuts the front end surface of the stationary armoury 5.

A smoothly curved convex portion 16 is formed on the abutment surface 15 of the rotating armoury 6, and this convex portion 16 is positioned by fitting into a smooth recess provided at the tip of the fixed armoury.
Smooth recesses are formed at two places at the tip of the fixed endpiece 5, and the projections 16 fit into these recesses, thereby determining the rotation angle of the rotary endpiece 6 and the position of the temple 2.

The rotating armoury 6 comes into contact with the tip of the stationary armoury 5 under the action of the spring force of the coil spring 13, and when the rotary armoury 6 rotates, the convex portion 16 formed on the contact surface 15 fits into the recess, thereby positioning it. Ru. Therefore, the crane 2 rotates together with the rotary armoury 6, and is positioned so as to stop at the position where the crane 2 falls down and at the position where the crane 2 stands up, as shown in FIGS. 5(a) and 5(b).
By the way, the rotational positioning mechanism of the rotary armoury 6 is not limited to the specific example shown in FIG.
