Description

The present invention relates to thin glasses that can be stored in a chest pocket or the like without being bulky when removed from the face and carried around.

Eyeglasses come in many forms and come in a wide variety of designs and decorations. In terms of functionality, materials such as titanium are used to make it lighter so that you will not feel tired even if you wear it for a long time. In addition, rimless glasses in which both lenses are directly screwed with a connecting member and the body armor is screwed on the outside of the lens are often used without providing a rim on the front part.

FIG. 10 shows general eyeglasses, which are attached to both sides of the front portion (a) so that the vines (b) and (b) can be folded. The front part (a) connects both rims (c) and (c) with a connecting member (d), and the body armor (e) and (e) are on the outside of both rims (c) and (c). It is brazed and configured, and the vines (b) and (b) are foldably connected to the armor (e) and (e) via hinges (f) and (f). The lenses (G) and (G) are fitted on the rims (C) and (C).

FIG. 11 shows a case where the vines (b) and (b) are folded with the glasses removed, and both vines (b) and (b) overlap each other. As is clear from the figure, the vines (b) and (b) are folded behind the front portion (a), and the thickness dimension H is relatively large. If it is myopia glasses, I always wear them, but I usually carry reading glasses in a glasses case to wear them when I work or read newspapers and magazines.

Two pairs of nose pads (chi) and (chi) are attached to the inside of the center of the front part (a), and both noses to support the front part (a) when wearing glasses. You can hit the side. As shown in FIG. 11, there is an appropriately sized gap between the folded vines (b) and (b) so that they do not touch the nose pad (chi) and (chi). ) And (ri) are formed.

The reading glasses you carry need to be as compact as possible. There is a limit to how small the vertical and horizontal dimensions of the front part can be because it hangs on the face, but by reducing the thickness dimension H in the folded state, the spectacle case to be accommodated becomes thinner.
However, with conventional eyeglasses, a modern vine that is curved along the head when worn is provided at the tip of the vine, and the vine is folded so as to overlap the back side of the front part, so that the thickness is reduced. Has a limit. Moreover, it is necessary to provide gaps (ri) and (ri) so as not to come into contact with the nose pad (chi) and (chi), and the thickness dimension H when the vine is folded is inevitably large.

In the "thin glasses" according to Japanese Patent Application Laid-Open No. 2015-90390, a joint is provided on the outside of the horizontal neutral axis of the front portion, and the shaft of the one-side joint is inclined from the outer upper side to the inner lower side with respect to the plane including the front part. , The shaft of the other side joint is inclined from the inner upper side to the outer lower side with respect to the plane including the front part, and when folding the vine connected to these inclined shafts, the vine connected to the one side joint is the upper side of the front part. The vine connected to the joint on the other side is located on the lower side of the front part.

In the "thin glasses" according to Japanese Patent Application Laid-Open No. 2009-69356, a broach is provided at a position where an inclined line inclined downward with respect to a horizontal baseline extending from the center of a substantially elliptical rim intersects the rim, and a joint is attached to the broach. At the same time, the shaft of the joint is parallel to the tangent of the rim at the above position, and the vine attached to the joint rises along the rim in a folded state so as to be flush with the front part, and then straight. The extended tip is curved and modern, and when the vine is open, it is inclined outward, and the connecting member that connects both rims is provided as a mountain shape on the lower side of the rim.
"Thin glasses" according to Japanese Patent Application Laid-Open No. 2015-090390 "Thin glasses" according to JP-A-2009-69356

In this way, there are various types of thin eyeglasses configured so that the reading eyeglasses can be compactly folded and carried. As described in the above conventional literature, when both vines are folded, they may be located on the upper side of the front part, or one vine may be located on the upper side of the front part and the other vine may be located on the front part. If it is located on the lower side, the glasses with the vines folded will be thinner.
However, if the folding position of the vine is flush with the front part and is configured to be located on the upper side of the front part or the lower side of the front part, the vine joint structure of the spectacle frame becomes complicated, and therefore the manufacturing is difficult. It's a hassle.
The problem to be solved by the present invention is this problem. By changing the inclination of the joint and by changing the inclination of the joint, the vine is folded while twisting, and the thickness of the curved modern is eliminated. We provide thin glasses that can be folded close to the back of the front part.

The thin eyeglasses according to the present invention have foldable vines attached to both sides of the front portion, and have the same basic structure as conventional eyeglasses. Here, the body armor is provided on both sides of the front portion, but the body armor constituting the thin glasses of the present invention is not a substantially L-shape as in the conventional case, but is basically a straight member extending outward, and this straight body is used. It is attached to the body armor so that the vine can be folded via a joint such as a hinge.
However, although it may be an L-shaped body armor, the length of the L-shaped body armor extending rearward is shortened.

By the way, conventional joints such as hinges are provided along the body armor and the vine, and the joint shaft extends in the vertical direction, but in the present invention, it is tilted with respect to the body armor and the vine. Therefore, although the joint shaft is tilted inward or outward (left-right direction or front-back direction) and not in the vertical direction, the specific tilt angle of the joint is not limited.
Further, the joint is inclined with respect to the direction of the vine and the twist, and the joint shaft is not parallel to the front portion but is inclined in the front-rear direction or the left-right direction.
As a result, the vines that are folded through the joint are folded while twisting, and while eliminating the thickness of the curved modern, they are close to the back of the front part, and the glasses on which the vines are folded become thinner.

The glasses according to the present invention are folded while twisting both vines, and by eliminating the curved modern thickness, no large gap is left between the glasses and the front side, and the glasses become thinner and can be used in chest pockets, etc. Can be easily accommodated. In particular, if the body armor is made on the same surface as the front portion and extends outward, and a joint such as a hinge is provided on the body armor, the thickness on the joint side is also reduced.

The plan view which shows the thin glasses which concerns on this invention. A form of joint for folding the vine of thin glasses according to the present invention while twisting the modern. Top view of the vine folded using the joint shown in FIG. The rear view of the vine folded by using the joint shown in FIG. (A) is a form of a joint for folding the vine of the thin glasses according to the present invention while twisting the modern, and (b) is a rear view of the vine folded using the joint shown in (a). A form of joint for folding the vine of thin glasses according to the present invention while twisting the modern. A vine folded using the joint shown in FIG. A form of a vine in which the vine of the thin glasses according to the present invention can be folded without touching the nose pad. When a joint is provided on a straight twist. Conventional general glasses. When the vine of conventional glasses is folded.

FIG. 1 is an example showing a plan view of the thin glasses according to the present invention, and vines 2a and 2b are attached to both sides of the front portion 1 so as to be foldable. The front portion 1 is provided with both rims 3a and 3b connected by a connecting member 4 curved in a chevron shape, and armor 5a and 5b brazed to the outside of the rim. Then, joints 6a and 6b are attached to the armor 5a and 5b, and the vines 2a and 2b are connected via the joints 6a and 6b so as to be foldable.

By the way, the body armor 5a and 5b are formed of linear members instead of the substantially L-shape as shown in FIGS. 10 and 11. Then, joints 6a and 6b are brazed to the linear body armor 5a and 5b, and vines 2a and 2b are attached via the armor 5a and 5b. The bases of the vines 2a and 2b are bent into an L shape, and the bases 7a and 7b are brazed to the joints 6a and 6b so that the vines 2a and 2b can extend to the rear on both sides of the front portion 1.

In the thin glasses of the present invention, the joints 6a and 6b connecting the vines 2a and 2b are tilted so that the vines 2a and 2b are folded close to the back surface of the front portion 1.
FIG. 2 shows a joint capable of connecting the body armor and the vine, (a) is a side view, (b) is a front view, and the joint 6 is tilted as shown in the figure.
The tip side faces upward with respect to the body armor 5, so that the joint shaft tilts outward.

By the way, the vine 2 attached via the joint 6 shown in FIG. 2 is folded as shown in FIG. 3 (a). FIG. 3B shows a case where the joint is folded through a conventional joint, but by using the joint 6, the modern 7 provided at the tip of the vine is folded while being twisted.
As shown in FIG. 3 comparing the conventional vine and the vine 2 of the present invention, the modern portion indicated by a circle becomes thinner in the vicinity of the front portion 1.
Then, as shown in FIG. 4, the vine 2 folded close to the front portion 1 is located below the nose pad pads 8a and 8b, and the modern 7 at the tip portion greatly extends downward.

FIG. 5 shows another mounting form of the joint 6, which is inclined. That is, the joint piece (butterfly piece) brazed to the body armor 6 side is higher and the joint piece (butterfly piece) brazed to the vine 2 is lower because it is inclined diagonally with respect to the body armor 6 and the vine 2. I am trying to be. Therefore, the joint shaft is inclined in the front-rear direction.
Then, the vine 2 attached to this inclined joint is folded, but the state extends upward as shown in FIG. 5 (b), and the modern is located above the front part. Become.

FIG. 6 shows yet another form of mounting structure for the joint.
(A) shows a side view of the joint, and (b) shows a front view of the joint. The joint is slanted and slanted and brazed to the armor 5 and the vine 2. That is, the joint form shown in FIG. 2 and the joint form shown in FIG. 5 are combined. Therefore, the vine 2 attached to the inclined / inclined joint in this way is located near the nose pad as shown in FIGS. 7 (a) and 7 (b), and is folded in a state close to the front portion. Get caught. That is, both vines 2 and 2 are folded close to the center back of the front portion to form thin glasses.

FIG. 8 shows an example of the form of thin glasses when both vines are folded.
(A) represents the case where both vines are folded close to the upper side of the nose pad, and (b) shows the case where both vines are located below the nose pad and folded. c) represents the case where both vines are folded on the upper side of the nose pad.
In this way, the folding positions of both vines have changed, but this can be adjusted by changing the inclination angle and the inclination angle of the joint 6.

FIG. 9 shows an enlarged view of part A in FIG. One wing piece 10a constituting the joint 6 is fixed to the armor 5 brazed to the outside of the rim 3, and the base 7 of the vine 2 is fixed to the other wing piece 10b. The gap formed between the shaft 9 of the joint 6 and the back surface of the front portion 1 is small, and therefore the joint side of the vine 2 that is swiveled and folded around the shaft 9 is also on the back surface of the front portion 1. You can approach.
However, the body armor 5 may be roughly L-shaped as in the conventional case, and when this L-shaped body armor 5 is used, the shaft 9 of the joint 6 is not extended to the back side as much as possible. It is necessary to install it nearby.
