Description

[Detailed explanation of the invention] This invention relates to glasses that can be folded thinly.
To provide a pair of eyeglasses which are convenient to carry and which do not cause the tendrils and lens frames to overlap when folded and are not bulky when stored in a pocket of clothes.

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

The glasses have left and right lens frames 1 and 2 connected by a bridge 8, and a support piece 12 protruding from the outer end of the upper side 11 of both lens frames 1 and 2.
The vines 4, 4, which are the characteristics of the present invention, are connected in a foldable manner.

The tendril 4 is formed of an auxiliary tendril 5 having a length corresponding to the vertical width of the lens frames 1 and 2, and a tendril main body 6 equipped with an ear hook 61, and the auxiliary tendril 5 has a protrusion at the base end as shown in FIG. Installed stopper piece 51.51
Receiving plates 13, 13 protruding from the inner surface of the support piece 12 are fitted between the support pieces 12, and are pivotally fixed by a pin 14 so as to be foldable in a plane perpendicular to the lens frames 1, 2.

A torsion spring 15 is fitted into the pin 14, and the auxiliary vine 5
is biased in the direction of expansion.

A vine main body 6 is pivotally fixed to the tip of the auxiliary vine 5 so as to be foldable in a plane perpendicular to the rotational plane of the auxiliary vine 5.

Therefore, when the vine 4 is folded, the vine 4 and the lens frames 1 and 2 do not overlap and the glasses become flat as shown in FIG.

Receiving pieces 7 and 7a each having a guide hole 71 are provided on the same straight line on the upper sides 11 and 11 of both lens frames 1 and 2, and a bridge 8 is slidably fitted into each guide hole 71.

The bridge 8 is formed of a metal band plate, and is arranged with the plate surface parallel to the upper side 11.11 of the lens frame, or with the plate surface perpendicular to the upper side of the lens frame as shown in FIG.

A fixing screw 91 is screwed into one end of the bridge 8, and a plurality of screw holes 82 are opened in a row at intervals of about 3 screws at the other end.

In the middle of each screw hole 82, 82 there is a cut groove 83.8 on both sides.
3, and when the lens frame is adjusted to the interpupillary distance, the excess length of the bridge 8 is cut off at the groove position.

An adjustment screw 92 is screwed into the screw hole 82 at an appropriate position according to the interpupillary distance, and both screws 91 and 92 serve as retainers 9 and 9 for the bridge 8.

However, when fitting the glasses to the wearer, if the distance between the wearer's pupils and the distance between the lens frames 1 and 2 do not correspond, the adjustment screw 92 is removed and the bridge 8 is retracted from the receiver pieces 7 and 7a. Then, the distance between the lens frames 1 and 2 is optimally adjusted.

Next, insert the adjusting screw 92 into the screw hole 8 corresponding to the outer end of the receiving piece 7.
2 and cut off the excess portion of the bridge 8.

As a result, when the lens frames 1 and 2 are pulled outward until the screws 91.92 at both ends, that is, the retainers 9.9 touch the outer ends of both receiving pieces 7 and 7a, the distance between the lens frames 1 and 2 is The distance between the pupils always corresponds, so the eyes don't get tired.

Also, since the retainers 9, 9 do not protrude from the outer ends of the receiving pieces 7, 7a, the appearance is good.

When the lens frames 1 and 2 are brought close to each other, placed in the case 20 as shown in FIG.
2. The vines 4 are all arranged in parallel on the same plane and can be folded into a flat shape, making it convenient to carry.

Furthermore, when the lid 21 is opened, the tendrils 4 are released by the action of the torsion spring 15.
, 4 stand up in a crossed state, making it convenient to take out.

In addition, when the plate surface of the bridge 8 is arranged parallel to the upper side 11 and 11 of the lens frame as shown in FIGS. 1, 2, and 4, the expansion and contraction operation between the lens frames 1 and 2 The sliding resistance of the bridge 8 is reduced, and the bridge 8 is not caught in the receiving pieces 7, 7a and can be operated smoothly.

When implementing the present invention, the bridge 8 is fixed to one of the receiving pieces 7a.

Alternatively, it is of course possible to directly protrude from one lens frame 1.

It goes without saying that the present invention can also be applied to eyeglasses in which the lens frames 1 and 2 are connected and fixed by a bridge integral with the lens frame, as in conventional eyeglasses.

In the present invention, as described above, the vine 4 is composed of the auxiliary vine 5 and the vine main body 6, which are pivotally connected so as to be foldable so as to surround the lens frames 1 and 2, so that when folded, the vine 4 The lens frames 1 and 2 do not overlap and are flat, so they have excellent practical effects, such as being able to be carried in a bulky manner even when stored in a pocket.
