Description

  The present invention is an improvement of the temple frame attaching / detaching structure of the spectacle frame, more specifically, it is possible to easily replace a damaged temple, and it is convenient when changing the temple to a desired design, The present invention relates to a temple frame temple attachment / detachment structure that can improve the fit when worn.

  As is well known, the temples of the spectacle frame not only have a functional role of holding the lens of the front frame in front of the eyes, but also have a design role to change the overall impression of the frame by its design.

  On the other hand, because many temples are elongated, they can easily be damaged if you accidentally step on the eyeglass frame or place objects on top of it, and the modern part of the temple is also around the ears and sides. Because it is a part that directly touches the skin, such as the head, fading and deterioration due to sebum are likely to occur.

  For this reason, there is an opportunity to change the temple to another type with a different design, or to replace it with a new one that is not damaged. Since it was necessary to remove the screws and replace the parts, and then retighten the screws again, it was not only troublesome to replace, but the removed screws could be lost.

  Therefore, conventionally, as described in <Patent Document 1>, the temples of the spectacle frame are divided into front and rear, a mounting hole having a window hole at the top is provided at the rear end of the front temple, and the rear temple is provided. A mechanism has been proposed in which an elastic piece-like claw that can be inserted into the mounting hole and locked into the window hole is provided at the front end portion of the front temple so that the rear temple can be easily attached to and detached from the front temple.

  However, in the above-described conventional temple structure, since the window hole is provided in the upper surface of the rear end portion of the front temple, the temple is apt to be thick, and the eyeglass frame tends to be left unattended.

  Conventionally, in the above-described separation-type temple, as shown in <Patent Document 2> or <Patent Document 3>, a technique for providing a window hole on the side surface of the front (rear) end of the temple has also been proposed. However, both of them have a structure in which the rear end portion of the front temple and the front end portion of the rear temple are tightly fitted, so that the rigidity of the connecting portion is increased and the flexibility of the temple is lowered. There was a fault that the feeling of fitting to was impaired.

  By the way, in the spectacle frame, a spring hinge mechanism that can fit the temple to the temporal region by an urging force is often used (see, for example, Patent Document 4). When it was attempted to be incorporated into a temple, the structure near the hinge was extremely complicated and the manufacturing cost was increased, and the design surface was partly more profound and it was easy to achieve an unbalanced design.
