FIG. 7 is an exploded perspective view showing a part of the configured eyeglasses, FIG. 7 is an exploded perspective view showing a part of the eyeglasses configured by using another conventional hinge part, and FIG. 8 is a perspective view illustrating another conventional hinge part. FIG. 3 is an exploded perspective view showing a part of the eyeglasses configured as described above.

First, eyeglasses of a first embodiment constructed by applying the present invention will be described with reference to FIGS. 1 to 3. In the figure, what is designated by reference numeral 1 is a temple for hanging on the ear of a spectacle wearer, and is composed of a metal wire material having elasticity capable of bending. As shown in FIG. 1, a loop-shaped pivotally supporting portion 11 is curvedly formed on the base end side of the temple 1. The pivot portion 11 is a component corresponding to the bridge portion 1a in the conventional hinge component shown in FIG. 6 or 7. In the conventional piece 1a, it is necessary to perform a perforating process on a substantially triangular block piece, and then braze the piece 1a to the base end side of the temple 1 which is a very troublesome work. However, in the pivot portion 11 of the present embodiment, it is only necessary to bend the base end side of the metal wire rod, and it is not necessary to perforate or braze as described above. The size of the loop of the pivotal support portion 11 can be adjusted to a required size depending on the bending condition, but in this embodiment, it is formed to a size slightly larger than the diameter of the pivotal support pivot described later. The shape of the loop of the pivot 11 may be any shape as long as the pivot 11 performs the hinge function, and it may be formed in a hook shape, a spiral shape, or a polygon such as a triangle or a quadrangle. It is also possible.

What is designated by reference numeral 2 is an end piece composed of a bracket member connected to the front F of the spectacles. As shown in FIG. 1, a pair of upper and lower pieces 21 and 21 project from one end of the end piece 2, and the pivot portion 11 of the temple 1 can be received between the pieces 21 and 21. It has become. And, hole portions 22 and 22 penetrating vertically are formed in the piece portions 21 and 21, respectively. In the present embodiment, the above-mentioned end piece 2 of the so-called "Sparta Satoshi" type is used in the industry, but the end piece 2 of the type in which two pieces are brazed as shown in FIG. Alternatively, it is of course possible to adopt other types of end pieces.

What is indicated by reference numeral 3 is a pivot pivot for connecting the temple 1 and the end piece 2, and in the present embodiment, a screw is used as the pivot pivot 3. When connecting by this pivot support pivot 3, with the pivot support 11 of the temple 1 inserted between the pieces 21 of the end piece 2, the pivot support pivot 3 is connected to the holes 22. The pivot support 11 is inserted and axially supported from above. Then, as shown in FIG. 2, the temple 1 and the end piece 2 are hinge-connected, and the spectacles as shown in FIG. 3 can be obtained more easily and quickly than in the case where the conventional hinge parts are used. Further, in the spectacles of this embodiment, since the component corresponding to the conventional piece 1a is made of the curved metal wire, the piece 1a is not used during use like the conventional spectacles. There is nothing to do. Further, although the pivotal support portion 11 of the temple 1 has a simple structure in which only a metal wire rod is curvedly formed, the temple 1 can be appropriately rotated by tightening the pivotal pivot 3 as in the case of conventional glasses. It is possible to secure the resistance (again), and thus the smooth opening / closing operation of the temple 1 is surely realized.

Next, eyeglasses according to a second embodiment of the present invention will be described with reference to FIGS. 4 and 5. This embodiment is an example in which the pivot portion 11 of the temple 1 of the first embodiment is provided on the end piece side. As shown in FIG. 4, what is designated by reference numeral 1 is a temple to be worn on the ear of the spectacle wearer. A butterfly piece composed of a pair of upper and lower pieces 12 and 12 is brazed to the base end side of the temple 1, and holes 13 and 13 are formed in the pieces 12 and 12 so as to penetrate vertically. There is.

What is indicated by reference numeral 2 is an end piece connected to the temple 1 and is mainly composed of a bendable elastic metal wire rod. The end piece 2 is brought out rearward from a rim R that constitutes the front F, and a loop-shaped pivotally supporting portion 23 is curvedly formed at the take-out end portion. The pivot portion 23 is a component corresponding to the bridge portion 2a in the conventional hinge portion product shown in FIG. In the case of the conventional piece 2a, it is necessary to perform a complicated operation of drilling a substantially triangular block piece and then brazing the piece 2a to the end of the end piece 2. In the pivot part 23 of the present embodiment, it is necessary to perform a very simple bending process of bending the base end side of the metal wire rod protruding from the plate piece taken out from the rim R into a loop shape. Good. Then, the pivotally supporting portion 23 curved in this manner is inserted between the bridge portions 12 of the temple 1, and a pivoting pivot (screw in this embodiment) designated by reference numeral 3 is inserted into the hole portion 13 of the temple 1. When the shaft 13 is inserted and pivotally supported by the pivotal support portion 23, the temple 1 and the end piece 2 are hinge-connected to each other, so that eyeglasses as shown in FIG. 5 can be easily obtained.

The embodiment of the present invention is generally as described above, but the present invention is not limited to the above-mentioned embodiment, and various modifications can be made within the scope of the “claim for utility model registration”. However, for example, in the present embodiment, although the metal wire is curved and the loop-shaped pivot portion is provided, the engineering plastic material is injection-molded to the end of the temple 1 or the end piece 2. It is also possible to provide a loop portion, and it goes without saying that such a change belongs to the technical scope of the present invention.
