Abstract

<P>PROBLEM TO BE SOLVED: To provide a hinge for eyeglasses that allows a temple to be smoothly opened or closed with a simple configuration, thus gives soft feeling and a good comfort. <P>SOLUTION: When a user wears the eyeglasses, the temple 3 receives outward force by rotating further outward from the position where a protrusion 8 of the inner hinge 4 of the temple 3 abuts on the peak 10 of the outer hinge 2 of a joint 1. The locking part 13 of an elastic plate 5 receives pressure applied by a pin 9 of the inner hinge 4 of the temple 3. On the other hand, since the flat end 14 of the elastic plate 5 is locked at the peak 10 of the outer hinge 2, the elastic plate 5 is deformed so as to swell outward. By the deformation, the temple 3 can be rotated outward while maintaining proper inward pressure. <P>COPYRIGHT: (C)2011,JPO&amp;INPIT

Description

  The present invention relates to a hinge structure that rotatably supports wisdom and temples, which are constituent members of eyeglasses.

  Glasses are required to fit on the wearer's face. For this reason, at present, various devices such as providing an elastic member on a part of the temple, interposing an elastic member on the connecting part between the wisdom and the temple, or the hinge part that rotatably supports the wisdom and the temple, etc. To improve the fit.

  As described in Patent Document 1, the applicant of the present invention interposes a flat body in which a slit portion is provided in part and two elastic arm portions are formed between an outer hinge body and an intermediate hinge body. When one of the elastic arm portions is locked to a part of the outer hinge, the other is locked to a part of the middle hinge, and when the temple is opened outward with respect to the wiping, Although the slit portion is narrow and is configured to give a resilient force to each locking portion, it has a simplified structure, but there is no part that is uncomfortable as an eyeglass, and it has a sense of unity and luxury. We proposed a pair of eyeglass hinges that can be pushed out and smoothly opened from the state where the outer surfaces of Satoshi and Temple are the same surface.

Japanese Patent No. 3000044

  However, the eyeglass hinge described in Patent Document 1 is structurally simplified as compared with other configurations of this type, but is still sufficiently satisfied with the opening / closing feeling of the temple and the feeling of fit. It was not a thing.

  Accordingly, an object of the present invention is to provide a hinge for a pair of glasses having a simple configuration, which allows a temple to be opened and closed smoothly, and which can provide a soft and good fit feeling, in order to solve the above-described problem of a conventional pair of glasses. To do.

The present invention is an eyeglass comprising an outer hinge body and an inner hinge body, wherein the outer hinge body and the inner hinge body are rotatably connected to each other by a rotating shaft, and the wisdom and the temple are rotatably supported. A protrusion projecting in the circumferential direction and a projecting section projecting in a direction perpendicular to the circumferential direction on one of the outer hinge body and the inner hinge body, and the other on the other A crest is formed to lock the protrusion, and one end is held by the rotating shaft inside the outer hinge and the inner hinge, and the other end is rotated when the temple rotates. arranged spiral elastic plate elastically contacts one side of the crest, the protrusions, to provide a biasing force to the elastic plate when the second end portion and the crest portion has elastic contact of the elastic plate Further, the elastic plate is locked to a locking portion extending from the one end portion to the circumferential portion.

  In the present invention, by providing a spiral elastic plate inside the hinge, an appropriate urging force can be given to the wisdom when opening and closing the temple. The elastic plate has a spiral shape, and there is always no urging force, and the temple fits well on the face of the spectacle wearer. In addition, the present invention has an excellent effect for spectacles, such as being structurally less complicated than the conventional one.

FIG. 3 is a view showing the outer hinge portion of the wisdom in this embodiment, (a) is a side view, (b) is a plan view, and FIG. 4 is a spiral elastic plate in this embodiment. (A) is a top view, (b) is a side view.

  In FIG. 1, reference numeral 1 is an arm having an outer hinge body 2, 3 is a temple having an inner hinge body 4, and 5 is an elastic plate disposed inside the outer hinge body 2 and the inner hinge body 4. A hinge 6 comprising an outer hinge body 2 and an inner hinge body 4 rotatably connects the wisdom 1 and the temple 3 with a rotating shaft 7 made of a screw member with an elastic plate 5 interposed therebetween.

  In FIG. 2, the temple 3 has a pair of inner hinge bodies 4 that form an annular shape in plan view at the end, a protrusion 8 that protrudes on the circumferential side is formed, and a protrusion that protrudes in a direction perpendicular to the circumferential direction. The pin body 9 which is a portion is configured to be fitted.

  In FIG. 3, the wi 1 has a pair of outer hinge bodies 2 in which the end portion has an annular shape in plan view and the inner hinge body 4 is inserted into the gap portion A, and the protrusion of the temple 3 is interposed between the outer hinge bodies 2. A peak portion 10 for locking the portion 8 is formed.

4, the elastic plate 5, Ri tabular ones der forming a spiral, a circular portion 11 which has one end portion is supported by the rotation shaft 7 portion, extending from the annular portion 11 in the circumferential portion 12 It consists of a locking portion 13 to be engaged and a flat end portion 14 at the other end. The elastic plate 5 is fitted between the inner hinges 4 of the temple 3.

  FIG. 5 is a view showing a state in which the hinges of the wisdom and the temple are assembled in the present embodiment, wherein (a) is a side view, (b) is a plan view, and FIG. 6 is an elastic view of the hinge in the present embodiment. It is a figure which shows the state at the time of heating, (a) is a side view, (b) is a top view. 7 and 8 are perspective views for explaining the operation of the main part of the hinge in the present embodiment.

  In a state where the outer hinge body 2 and the inner hinge body 4 of the hinge 6 are connected by the rotating shaft 7 with the elastic plate 5 interposed therebetween, the circumferential portion 12 of the elastic plate 5 winds the outer peripheral portion of the rotating shaft 7. It is arranged between the pair of inner hinge bodies 4 of the temple 3 so as to rotate. Further, the flat end portion 14 of the elastic plate 5 is elastically contacted with one side (left side in the drawing) of the peak portion 10 of the outer hinge 2 so as to be able to contact and separate, and one side (left side in the drawing) of the locking portion 13 of the elastic plate 5. ) Is in elastic contact with the pin body 9.

  When the pin body 9 is in elastic contact with the locking portion 13 of the elastic plate 5, a biasing force is generated in the elastic plate 5 in a direction in which the flat end portion 14 of the elastic plate 5 and the peak portion 10 of the outer hinge body 2 are in elastic contact. The pin body 9 can move in an annular space B formed between the annular portion 11 and the circumferential portion 12 of the elastic plate 5.

  In the assembled state as described above, as shown in FIG. 5, when the temple 3 is rotated inward (clockwise) about the rotation shaft 7, the peak portion 10 of the outer hinge body 2 of Ji 1 is used. On the other hand, the protrusion 8 of the inner hinge body 4 of the temple 3 is separated, and the pin body 9 of the inner hinge body 4 of the temple 3 is interposed between the annular portion 11 and the circumferential portion 12 of the elastic plate 5 as shown in FIG. The formed annular space B is moved clockwise. Thereby, when the temple 3 rotates inward, for example, when the temple 3 is folded, the elastic plate 5 does not interfere with the rotation of the temple 3 at all and smooth rotation is performed.

  Further, for example, when the temple 3 comes into contact with the face of the wearer and an external force acts on the temple 3, that is, as shown in FIG. When the temple 3 is further rotated outward (counterclockwise direction) from the position where the projection 8 of the inner hinge body 4 of the three contacts, the locking portion 13 of the elastic plate 5 is the inner hinge body of the temple 3. 4 is pressed by the pin body 9.

  On the other hand, as shown in FIG. 8, the flat end portion 14 of the elastic plate 5 is locked at the peak portion 10 of the outer hinge 2, so that the elastic plate 5 is deformed so as to bulge outward. Thereby, the temple 3 can be rotated outward while maintaining a suitable pressure inward.

  The elastic plate 5 may be a spiral flat plate. The specific shape and material of the elastic plate 5 depend on the shape and size of the hinge 6, the fitting force at the time of wearing, or the specs of the glasses. However, the present invention is not limited to the configuration of the present embodiment.

  The present invention is applied to a hinge for rotatably connecting spectacles and temples of glasses.
