ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to spectacles, more specifically, to spectacles having a new front-part structure in which lenses can easily be fitted, broaches as in conventional spectacles are not required, and legs to which nose pads are attached are not provided by brazing, and a new temple joint structure in which the temples can be attached stably without loosening.
2. Description of the Related Art
Conventionally, spectacles comprise a front part and temples. The front part has lenses fitted in rims thereof, and the temples are foldably attached to both outsides of the front part.
The front part of the spectacles has the rim for fitting the lenses. A metallic spectacles frame has broaches for extending the periphery length of the rim when fitting or taking off the spectacles. As shown in
FIG. 10
, the broach has such a structure that a broach
52
is brazed to the outside of a rim
51
, which is cut together with the rim
51
so as to form broach pieces
53
and
54
, and both of which can be tightened to each other with a screw.
The front part of the spectacles is not only the above-described form having the rim, but a form called rimless spectacles having no rim in which the lenses are directly attached with screws, and a form called a nylon frame having a half rim at the upper half of the lenses and in which the lower half is held with a high-tension filament such as a metal filament.
On the other hand, the rim of the front part has lenses fitted therein. In addition, nose pads are attached to the front part, for putting and supporting the front part on the nose when putting on the spectacles. The nose pads are each attached to an end of a leg brazed to the front part. That is, the nose pads are fitted in an attaching part called a box leg brazed to the end of the leg. Therefore, in such a structure for attaching the nose pads, it takes a long time to manufacture and attach, and also problems occur in that the brazed part comes off and the nose pad is removed. The front part structure of the conventional spectacles has the problems as described above.
In the conventional spectacles, a hinge is generally used as a temple joint structure. The hinge has two hinge pieces that can be bent around a shaft screw as the center, and the hinge pieces are brazed to the front part and the temple, respectively.
In a spectacle frame to which the temple is attached using the hinge, a forged temple and a forged wraparound endpiece are used in order to have a planar surface to which the hinge pieces of the hinge can easily be brazed. That is, if there is not an enough brazing area, the parts will come off. Therefore, the temple of the spectacles frame formed of a thin wire material cannot ensure sufficient brazing area, so that it is not suitable for using the hinge as a joint.
On the other hand, in a slim spectacle frame formed of the thin wire material, the conventional temple joint structure using the hinge spoils the appearance of the frame and is not applicable in view of design. Although manufacturing a small hinge that does not spoil the appearance can of course solve the problem, it is difficult to manufacture such a small hinge. It is also difficult to support the long temple with the small hinge, and the hinge may become loose so that the position of the spectacles may slip when putting on the spectacles. As described above, the conventional spectacles have the problems in the temple joint structure.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide spectacles using a new front structure that is different from the conventional front structure, in which lenses can easily be fitted, in which there is no need for the broach as in the conventional spectacles, and in which legs to which nose pads are to be attached are not provided by brazing, and a new temple joint structure in which the temple can be stably attached without loosening.
In order to solve the above problems, spectacles according to the present invention comprise a front part for holding lenses, and temples foldably attached to both outsides of the front part. The front part structure includes an upper frame having upper rim pieces on both ends of a connecting part, and a lower frame having lower rim pieces on both ends of the connecting part, in which the upper and lower frames are retained to each other at the center, in which wraparound end pieces provided on the outside of the upper and lower rim pieces are connected to each other so as to assemble the upper and lower frames, and in which legs to which nose pads are to be attached are continuously formed between the rim pieces and the connecting part of the upper frame or the lower frame. In the temple joint structure, rings formed by bending the upper and lower frames on the outside of the front part are provided at the upper wraparound endpiece and the lower wraparound endpiece, and also rings formed by bending ends of the temples are provided, in which the rings are assembled, a shaft is fitted in shaft holes without loosening, and which is tightened with a screw.
Other spectacles according to the present invention comprise a front part for holding lenses, and temples foldably attached to both outsides of the front part wherein the front part structure includes an upper frame having upper rim pieces on both sides of a connecting part, and lower rim pieces attached to the upper rim pieces, forming a pair, in which inner ends of the lower rim pieces are respectively retained to retaining parts formed between the upper rim pieces and the connecting part of the upper frame, in which wraparound end pieces provided on the outside of the upper and lower rim pieces are connected to each other so as to assemble the upper frame and the lower rims, and in which legs to which nose pads are to be attached are continuously formed between the upper rim pieces and the connecting part of the upper frame; and the temple joint structure has rings at the upper wraparound endpiece and the lower wraparound endpiece, the rings being formed by bending the upper frame and the lower rim pieces on the outside of the front part, and which has also rings formed by bending ends of the temples, in which the rings are assembled, a shaft is fitted in shaft holes without loosening, and which is tightened with a screw.
Furthermore, other spectacles according to the present invention comprise a front part for holding lenses, and temples foldably attached to both outsides of the front part, wherein the front part structure includes an upper frame having upper rim pieces on both sides of a connecting part and lower rim pieces attached to the upper rim pieces, forming a pair, in which inner ends of the lower rim pieces are respectively retained to retaining parts formed between the upper rim pieces and the connecting part of the upper frame, in which wraparound end pieces provided on the outside of the upper and lower rim pieces are connected to each other so as to assemble the upper frame and the lower rim pieces, and in which legs to which nose pads are to be attached are continuously formed between the upper rim pieces and the connecting part of the upper frame; and the temple joint structure has rings at the upper wraparound end pieces on the outside of the front part, the rings being formed by bending the upper frame, and which has also rings formed by bending ends of the temples, in which the rings are assembled, a shaft is fitted in shaft holes without loosening, and which is tightened with a screw.
Furthermore, other spectacles according to the present invention comprise a front part for holding lenses, and temples foldably attached to both outsides of the front part, wherein the front part structure includes an upper frame having upper rim pieces on both sides of a connecting part and lower rim pieces attached to the upper rim pieces, forming a pair, in which inner ends of the lower rim pieces are respectively retained to retaining parts formed between the upper rim pieces and the connecting par
