Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an eyeglass frame that has a special structure in which foldable temples are pivotally mounted on both outer sides of a lens fixing frame, thereby enhancing the aesthetic appearance.

Conventional eyeglass frames are provided with foldable temple portions via hinges on end pieces protruding from both outer sides of a lens fixing frame. Therefore, if the hinge is a hinge, it is manufactured from the same material and is used by welding to the end of the temple part or the end of the lens fixing frame. For this reason, the hinge part is uniform in design,
To prevent this, we have devised measures such as placing the vines on the inside so that they are not visible from the outside.

In addition, the lens frame disclosed in Japanese Utility Model Publication No. 33-11372 has a part of the lens frame made flat to form an elliptical temple holder, and the end of the temple is inserted into this temple holder, and the shaft is inserted through the shaft. I'm wearing it. Therefore, in this known example, it is necessary to flatten a part of the lens frame, and the linear temple is simply supported on this, so the design of the lens frame is not very beautiful. Furthermore, the temples swing from side to side about this axis, making it impossible to prevent the temples from opening outward, making it difficult to install the device reliably.

This invention actively uses the pivot joint between the lens fixing frame and the temple as a part of the design, which not only enhances the aesthetic appearance but also increases the strength of the pivot joint, preventing the temple from opening outward and making it strong. In addition, by applying this pivoting portion to the middle part of the temple or between opposing lens fixing frames, it is possible to easily create a foldable eyeglass frame. .

The present invention will be explained below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes the main body of a pivoting part provided at the tip of an end piece 5 protruding from the outside of one member, for example, a lens fixing frame of eyeglasses. An elliptical shape or a square plate with a perfect circle or an oval hole in the center is used, and an engagement member protruding from the end of the other member to be connected to the main body 1, such as the temple 4, is used. Fit piece 2. Therefore, the shape of the engaging piece 2 is formed to match the shape of a hole formed in the main body 1 so that it can be fitted into the main body 1.

The engagement piece 2 provided at the end of this temple 4 is shown in FIG.
As shown in FIG. 4, since the engagement piece 2 is provided on the outer surface of the temple 4, the engagement piece 2 protrudes from the side surface of the temple 4, and when the engagement piece 2 is fitted into the main body 1, the engagement piece 2 is inserted into the main body 1. 4 along one side of the main body 1 at its base end, and the engaging piece is completely fitted into the main body when the glasses are in use, as shown in FIG. 4A. .

Then, the engagement piece 2 is fitted into the main body 1, and the engagement hole 1a is arranged in a direction perpendicular to the folding direction of the temple so that the body and the engagement piece can be bent so that both the body and the engagement piece have the same axis. , 2a are bored, a female thread is carved in one of the engagement holes, a screw 3 is screwed into this, and the main body and the engagement piece are bent and engaged with this screw as the axis. It is something. In this case, the engagement hole on the main body side may be drilled only in a part of the ring part, but
In order to strengthen the pivot joint, it is preferable to drill holes in the vertically opposing parts. The main body 1 and the engagement piece may be made of the same material, but they may be made of different materials or colored differently in terms of design to make the appearance more beautiful.

When used as a pivot joint for folding glasses, in addition to the same shape as that used for the pivot joint between the lens fixing frame and the temple, two engaging pieces may be installed in one main body as shown in Figure 3. They are fitted in parallel on the left and right, and each engaging piece and the main body are locked by screw shafts, making it flexible, but this is done between the opposing left and right lens fixing frames, the middle part of the temple, etc. Applicable.

According to the present invention, a ring-shaped pivot body is provided protrudingly on one end piece, which is the other member, and an engaging piece is provided on the other member, the temple, and this engaging piece is attached to the base of the temple. The pivot joint is stronger than before because it protrudes from the side surface of the end, and the engaging piece is fitted into the hole in the main body, and the threaded shaft penetrates and locks the two. In addition, it has a beautiful external design, and can also be used as a hinge for folding glasses.Furthermore, since the temple comes into contact with the side surface of the main body of the pivoting part, it has the advantage of preventing the temple from opening outward.
