Description

  The present invention relates to a spectacle frame, and more particularly, to a spectacle frame made of metal or resin that can provide a soft wearing feeling using an elastic material.

  In order to obtain a soft wearing feeling, a super elastic material is used as a constituent member of the spectacle frame. A superelastic material is a material that deforms with a large strain when a force is applied, and returns to its original shape when the force is removed. In Patent Document 1, an alloy of titanium and nickel or a polyamide-based resin is described as a superelastic material, and a spectacle frame 110 as shown in FIG. 12 is described.

  The eyeglass frame 110 includes an elastic member 120 made of a superelastic material, in which a front end portion 132 that forms both ends of a front frame 130 including a bridge 131 and an armor portion 150 to which a temple portion 160 is connected via a hinge 180 are formed. Connected by. A lens frame 170 including a lens 140 is attached inside the front frame 130.

  By connecting the front frame 130 and the armored portion 150 with a superelastic material, the front frame 130 and the armored portion 150 can be bent or twisted with respect to each other in the elastic member 120. Thereby, a soft wearing feeling peculiar to a superelastic material can be obtained. In addition, it is firmly attached to the user's head and will not slide forward even if time passes. In addition, even when a large force is applied unintentionally in hanging, it is rarely deformed.

  However, the spectacle frame 110 has a problem that it is difficult to greatly change the design from the described form. That is, in the spectacle frame 110, the design is such that the end portion 150 of the front frame 130 is integrally and continuously formed on the front end portion 132 of the front frame 130, so that it is difficult to provide a great change. Moreover, since the elastic member 120 is designed so as not to be seen from the front, it is difficult to change the mounting form.

An outline of the spectacle frame 10 which is an example of the present invention will be described with reference to FIGS. The spectacle frame 10 is made of metal, but may be made of resin. Moreover, although it is set as the half rim type external appearance, it can also be set as a full rim type external appearance.
In the eyeglass frame 10, a front end portion 32 that forms both end portions of a front frame 30 including a bridge 31 and an armor portion 50 to which a temple portion 60 is coupled via a hinge 80 are connected by an elastic member 20. .

The lens frame 70 including the lens 40 includes a nose pad 75 and is attached to the inside of the front frame 30. The temple portion 60 is provided with a modern 65.
Since the temple part 60 rotates about the hinge 80, the rotation surface of the temple part 60 can be considered. Usually, the turning surfaces of the left and right temple portions 60 are substantially the same.

As shown in FIG. 4, the elastic member 20 includes an elastic main body portion 23 composed of a pair of spring pieces (a first spring piece 22 a and a second spring piece 22 b) sandwiching a U-shaped curved portion 21. . A connection piece 26 is provided on the extension of the second spring piece 22b.
Since it can be considered that the first spring piece 22a and the second spring piece 22b are elastically opened and closed in a plane including them, the surface indicated by XX on the elastic main body portion 23 is an elastic opening and closing surface. be able to.

  The first feature of the spectacle frame 10 of the present invention is that the front end portion 32 and the armor portion 50 are juxtaposed.

The eyeglass frame 10 shown in FIGS. 1 to 3 is the arrangement shown in the fifth arrangement example, and the elastic member 20 shown in FIG. 4 is a modification of the elastic member 20E in design.
That is, in the spectacle frame 10, the inner surface of the armored portion 50 and the lower surface of the front end portion 32 are connected by the elastic member 20. The outer portion of the first spring piece 22a is connected to the inner surface of the end portion 50. The upper end portion of the connection piece 26 is connected to the lower surface of the front end portion 32.

  Thus, the description of the arrangement of the front end portion 32 and the armored portion 50 is completed, and the description of the spectacle frame 10 is continued below.

As shown in FIG. 10, the hinge 80 in the eyeglass frame 10 uses an elastic body 85 as a frame on the temple portion 60 side.
That is, one piece is fixed to the end piece 50. The other frame is an elastic body 85 that extends long along the temple portion 60, and its tip 82 is fused to the temple portion 60 at a pin point.

And the inner surface 61 of the temple part 60 which the outer surface 81 of the elastic body 85 contacts is slightly curved, and only the part close | similar to the front-end | tip 82 is contacting.
For this reason, when a force that opens the temple portion 60 is applied, the elastic body 85 is deformed so as to bend along the temple portion 60, and the outer surface 81 of the elastic body 85 is in contact with the inner surface 61 of the temple portion 60 at a long distance. Deforms to adhere.

The elastic body 85 has a function similar to that of the elastic member 20, but has a slightly different role due to the following technical idea. In order to achieve the object of the present invention to obtain a soft wearing feeling, the elastic member 20 located at the front end portion 32 is more preferable than the elastic body 85 located at the temple portion 60.
For this reason, the elastic force of both is set so that the function for obtaining a soft wearing feeling is mainly caused to function by the elastic member 20 and the elastic body 85 is preliminarily functioned. In other words, the elastic member 20 normally functions, but the elastic body 85 functions when a large external force is applied by mistake.

As shown in FIG. 11, in the spectacle frame 10, a lens frame 70 including a lens 40 and a nose pad 75 is attached to the inside of the front frame 30.
11A is a partially enlarged view of FIG. 1, and FIG. 11B is a partially enlarged view of FIG.
The front frame 30 includes a connecting portion 35 in the vicinity of the bridge 31, and a lens frame 70 is connected thereto.

  FIGS. 11C and 11D show a lens frame 70 including the lens 40 except for the front frame 30 from FIGS. 11A and 11B. In the spectacle frame 10, the lens frame 70 is a half rim type, but may be a full rim type. By using a half rim type having a short joint with the lens 40, the lens 40 can be easily attached.
