JP2002031784A - Spectacle temple - Google Patents

Abstract

PROBLEM TO BE SOLVED: To solve such problems with the temple used heretofore for spectacles that, since the temples are heretofore not devised to eliminate a slip by intensifying grasping force, the non-slip spectacles are inevitably spectacles having a poor wearing feel. SOLUTION: The temple part of this spectacle temples is formed of a metal or an arbor-containing resin, and a tip part and the temple part are respectively horizontally curved and each of these curves comprises two peaks having a valley part at the front end of the ear bend or near the same.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an eyeglass vine which is hard to shift and has a good wearing feeling.

[0002]

2. Description of the Related Art Glasses that are easily displaced simply have a poor feeling of wearing,
Not only is it difficult to obtain a regular view, but there is also a risk of falling off and being damaged, which is of course undesirable. On the other hand, spectacles that are hard to be displaced by being strongly pinched by the spectacle vine are painful enough to cause a headache when worn for a long period of time, and this is not a preferable thing. In principle, eyeglasses can be put on the pad (the part that touches the nose that supports the eyeglasses) and the modern (the part that covers the back of the ear from the top of the ear at the tip of the temple). Therefore, it can be said that the pinching force of the vine and the curved shape of the modern make up for the fixing force. In other words, the pinching force that gives the feeling that "the vine is tightening the head" when wearing glasses is too strong to be troubled. Therefore, when actually purchasing and using the glasses, the adjustment of the temple clamping force, which is difficult to shift and does not overtighten, is an important and delicate operation.

[0003] Even if this adjustment work is performed quite perfectly, there is a limit to the adjustment that can be performed by a technician, for example, the application of a pinching force that does not cause any deviation even when playing sports. For this reason, a spring member is added to the rotating shaft part of the temple to provide a pinching force that is always urged, or a rubber cord or the like is used to connect the ends of both temples and go around the head when wearing. A method of responding with accessories such as fixing in shape is devised and actually sold.

[0004]

However, even in the case of the type using a spring member, the biased holding force is concentrated on the temple portion, so that the feeling of wearing is not always good, and the use of accessories is not always possible. Many people complain that they do not come across glasses with well-wearing vines due to problems such as troublesome wearing and poor appearance.

For example, when the eyeglasses G provided with a spring member to urge the pinching force are attached to the easily displaced eyeglasses, the vine T bends as shown in FIG. The curved shape moves outward from the regular position, and the fixing force of the glasses due to the shape of the modern M is impaired.

[0006]

In view of the above points, the present inventor has finally made the present invention as a result of intensive studies, and the feature of the present invention is that the temple portion is made of a metal or a resin containing a metal core. Wherein the modern portion and the temple portion are each curved in the horizontal direction, and these curves are formed by two peaks having a valley at the tip of the modern portion or in the vicinity thereof. The point is that it is composed.

[0007] Here, the "temple portion" is a main portion of a pair of rod-shaped members generally called spectacles, and is rotatably attached to the spectacle frame. The temple part and the eyeglass vine are generally common, but in this specification, the one that includes the connection structure with the eyeglass frame is the “glass vine”, and the one that does not include this is the “temple part”. ,
Is defined.

Further, the "temple section" has a "modern section". "Modern" is a part corresponding to the vicinity of the tip of the "Temple", and the strength member forming the Temple is covered with plastic or rubber with good skin contact. It is the position and size up to the part beyond the part that comes into contact with the ear when hung on the ear. However, for the glasses of the present invention, "modern"
Since the presence of is not essential, the "tip of the temple that covers the back of the ear from the top of the ear" will be referred to as the "modern part".

In the present invention, the modern portion and the temple portion are each curved in the horizontal direction. Where "horizontal"
Means that, when the surface on which the spectacle temple (assuming a straight line) rotates with respect to the lens is considered to be a horizontal plane, when the straight spectacle temple is curved in such a manner as not to protrude from the surface, It refers to the form of curvature. However, the curvature may be slightly modified so as to be combined with a curvature other than the horizontal direction.

[0010] The curvature is a matter to be appropriately determined in consideration of design problems and functional problems as long as the eyeglass temple does not come into contact with the skin, and the degree of curvature is not particularly limited. However, the curvature exists in the modern part and the temple part for one eyeglass temple.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in more detail with reference to the drawings.

FIGS. 1 (a) and 1 (b) show an example of an eyeglass temple 1 according to the present invention (hereinafter simply referred to as "the present temple 1"). It comprises a hinge 2, a temple section 3, and a modern 4.
Although only one side is shown, the temple 1 of the present invention is naturally used in a one-to-one pair.

The temple portion 3 and the modern 4 are curved in such a manner as to bulge outward, and a valley 5 is formed near the front end of the modern by these curves. In the case of this example, the degree of curvature is such that the distance d between the valley 5 and the most protruding portion is about 5
mm, but may be larger or smaller (not shown). However, in the range tested by the present inventor, if the distance d is 2 mm or less, the effect due to the curvature is often not obtained. If the distance d exceeds 10 mm, the feeling of wearing tends to be rather deteriorated. The result was favorable.

Next, FIG. 2 schematically shows a state where the temple 1 of the present invention is actually used. Since there are two curvatures, when viewed in a plan view as shown in the figure, the impression is somewhat strange, but the wearing person has no discomfort at all and has a very good wearing feeling. In addition, in a range where the person actually wearing the product is viewed with normal eyes, the design is somewhat unique and does not give a strange impression.

If the valley 5 comes into contact with the temporal skin when worn, a frictional force acts to shift the glasses when the temple muscle is moved, and the user may feel uncomfortable. Therefore, it is preferable to adjust the gap so that it does not come into contact with the skin.

[0016]

As described above in detail, the eyeglass temple according to the present invention has a temple portion made of metal or a resin containing a metal core, and the modern portion and the temple portion are each horizontal. Direction, and these curves are characterized by being composed of two peaks having a valley at the tip of the modern part or in the vicinity thereof. This is an extremely advanced invention having the effect of (1).

(1) The feeling of wearing is good. (2) The glasses are hard to shift. (3) There is no need for complicated mechanisms or additional parts.
