Description

[Detailed Description of the Invention] The present invention relates to a device that adjusts the length of the temples of eyeglasses to an appropriate length according to the shape of the user's face and head.

Because the distance between the face and the auricle differs depending on the person,
For vision correction eyeglasses, we manufacture multiple types of eyeglass frames with different temple lengths so that each individual can use a temple of the appropriate length. Therefore, this method requires a large number of stocks, which also increases costs, and with a fixed temple length, fine adjustment is difficult.

The present invention has been devised in view of this, and will be described below based on the illustrated embodiments.

In the figure, reference numeral 1 denotes an eyeglass frame having a desired design, and a foldable temple body 2 is provided at the outer end side of the frame 1. The temple body 2 is made of metal or synthetic resin and has a cylindrical shape over its entire length or at least the required length at its tip. This cylindrical part is into which a telescopic temple, which will be described later, can be inserted, and its shape varies depending on the cross-sectional shape of the telescopic temple. In the illustrated example, it is a flat rectangular cylinder, and its length is equal to the length required for the tip of the telescopic temple. is inserted, and an adjustment screw is also provided in this cylindrical portion 3. Adjustment screws 5 are fitted into both sides of this cylindrical part 3, and a window hole 4 is bored so that a part of the outer peripheral surface of the screw protrudes to the outer surface of the cylindrical part. 3, a screw rod 6 is made to protrude from the temple body side toward the opening direction of the distal end of the cylindrical portion. This threaded rod 6 is fixed to the temple body 2, and its screw direction is made to be different from that of a screw protruding from the tip of the telescopic temple, which will be described later. An auricle hooking piece 8 is integrally provided at the other end of the telescoping temple 7, and the shape of the tip of this temple is such that it can be inserted into the cylindrical body 3, and a threaded rod 9 is provided protruding from the distal end surface. do. When this telescopic temple is inserted into the cylindrical body, the opposing screw rods 6 and 9 are positioned on the same axis, and the ends of the screw rods 6 and 9 are adjusted to fit into the window hole. They are screwed together with screws 5 to become one piece. The threaded rods 6 and 9 and the adjustment screw 5 form a structure similar to a turnbuckle, and when the adjustment screw is rotated in the forward direction, the telescopic temple is inserted into the cylindrical body of the main body. The temple is made to protrude from the cylindrical body so that the length of the whole temple can be adjusted by expanding and contracting.

In addition, by carving a knurl on the outer periphery of the adjustment screw,
Further, by forming the screw into an uneven shape as shown in the figure, it is possible to easily rotate the screw by hand or fingers.

According to the present invention, the temple of the glasses is divided into a temple main body provided on the frame side and a retractable temple equipped with an auricle hook, and the tip of the retractable temple is slid into the cylindrical body of the temple main body. An adjustment screw that can be freely inserted and inserted, has threaded rods with different thread directions protruding from both the temple body and the telescopic temple, and which are fitted into the threaded rods into the window holes drilled in the cylindrical body. They are screwed together, and the length of the tendon can be expanded or contracted by rotating the screw in the forward or reverse direction, so it can be applied to everyone without having to strain frames with many different lengths of the temples, and can be finely adjusted. This has the advantage of ensuring proper fit for eyeglass wearers.
