Description

  The present invention relates to eyeglasses, and more particularly, to eyeglasses that have a simple structure, can be easily fitted to a user's head, and are comfortable to wear.

Glasses generally include a front part having a pair of left and right lenses, a temple part extending rearward from both sides of the front part, and a modern part attached to the temple part.
Such glasses are worn by sandwiching the user's head from both sides with the modern part and putting the modern part on the ear.

  By the way, when wearing spectacles, the shape of the head of the user varies depending on the individual, so the shape of the head may not match the shape of the modern part. In this case, the fit feeling of the modern part in the head is extremely deteriorated, and as a result, the glasses may be easily displaced, or an extreme headache may occur.

On the other hand, in recent years, the modern part has been improved in order to improve the fit of the glasses.
For example, the temple body has a temple main body whose base end side is connected to the eyelid of the spectacle frame, and a sandwich body that is coupled to the temple body and can sandwich the side surface of the face. The temple body and the sandwich body are the first links. The first link can rotate relative to the temple body about a first axis perpendicular to the longitudinal direction of the temple body, and the sandwiching body can rotate relative to the first link with respect to the first axis. The temple body and the sandwiching body are connected so as to be relatively rotatable around a second axis parallel to the temple body, and the sandwich body can slide relative to the temple body, and the sandwich body is the temple body. On the other hand, there is known a temple for eyeglass frame that is connected so as to be relatively rotatable around a third axis parallel to the first and second axes (see, for example, Patent Document 1).

JP 2008-102454 A

However, the temple for eyeglass frame described in Patent Document 1 has a drawback that the structure is complicated.
Further, since modern rotation is constrained by the torsion spring, when the modern is fitted to the head, a partial force by the torsion spring is transmitted from the modern to the head. As a result, the head is partially pressed, and the wearing comfort tends to deteriorate.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide eyeglasses that have a simple structure, can be easily fitted to a user's head, and are excellent in comfort.

  The inventors of the present invention have intensively studied to solve the above-described problems. It has been found that the above-mentioned problems can be solved by making the lens pivotable in the left-right direction, and the present invention has been completed.

  The present invention includes (1) a front part having a pair of left and right lenses, a main part bent along the user's head, and a modern part having an attachment protrusion formed to protrude outside the main part, A pair of linear temple parts connecting the one end of the front part and the attachment protrusion, wherein the attachment protrusion has a groove part into which the temple part is inserted, and the width of the groove part is that of the temple part. The eyeglasses are larger than the diameter in the cross section, and the modern part can be turned in the left-right direction with the mounting protrusion as a fulcrum.

  The present invention resides in (2) the spectacles according to (1), wherein the rotation of the modern portion is restrained by contacting the temple portion with the outer side wall portion of the groove portion in the groove portion.

  The present invention resides in the glasses according to (1) or (2), wherein (3) when the modern portion is rotated, a part of the temple portion moves while being guided by the bottom surface of the groove portion.

  This invention exists in the spectacles as described in any one of said (1)-(3) in which the front end of (4) main-body part is located ahead of an attachment protrusion.

  The present invention resides in (5) the spectacles according to any one of the above (1) to (4), wherein the bottom surface of the groove portion has a tapered shape spreading toward the front side in a top view.

  This invention exists in the spectacles as described in any one of said (1)-(5) in which the rear part of the main-body part has branched in the up-down direction.

  The present invention resides in the glasses according to any one of the above (1) to (6), wherein (7) the front portion of the main body portion branches in the vertical direction.

  The present invention resides in the glasses according to any one of (1) to (7), wherein (8) the modern part is detachable from the temple part.

In the glasses of the present invention, the width of the groove portion into which the linear temple portion is inserted is made larger than the diameter in the cross section of the temple portion, and the modern portion can be rotated in the left-right direction with the mounting protrusion as a fulcrum. Thus, the main part of the bent modern part can be easily fitted in accordance with the shape of the user's head.
In addition, since the modern portion can freely rotate within a certain range, unnecessary force is not applied to the modern portion when fitting, and the comfort is extremely excellent.
In addition, since no special link mechanism or the like is provided, the number of parts is small, cutting and welding are not required, and a simple structure with a low manufacturing cost can be achieved. Furthermore, since there is no cutting or welding, damage and the like are reduced.

  In the eyeglasses of the present invention, the temple part is brought into contact with the outer side wall of the groove part (hereinafter also referred to as “outer side wall part”) and restrains the rotation of the modern part, so the modern part rotates too much. This can be prevented.

In the glasses of the present invention, when the modern part is rotated, a part of the temple part moves while being guided by the bottom surface of the groove part, so that it is possible to prevent the front end or the rear end of the modern part from shaking in the vertical direction. it can.
Further, when the bottom surface of the groove portion has a taper shape that expands to the front side in a top view, the temple portion is in line contact with the main body portion or the outer side wall portion of the groove portion in the groove portion. Therefore, the impact due to the contact with the temple portion can be reduced.

  In the spectacles of the present invention, when the front end of the main body is positioned in front of the mounting protrusion, the stability when fitted to the head is excellent.

In the eyeglasses of the present invention, when the rear part of the main body part is branched in the vertical direction, the stability can be improved when fitted to the head.
Moreover, when the front part of the main body part branches in the vertical direction, the stability can be improved when the head part is fitted.
