DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to spectacles provided with a hanging frame, and more particularly, to a rotating device for selecting and holding the hanging frame at a plurality of angular positions with respect to the spectacle frame.

[0002]

2. Description of the Related Art In eyeglasses, in order to protect eyes from ultraviolet rays or the like, eyeglasses provided with a light shielding function are used. In order to provide a light-shielding function, there is a method of using a dyed lens (glass) for the lens itself, or a method of attaching the lens to a commonly used spectacle body so as to cover the light-shielding device. The latter method of using the light shield is extremely convenient because the use state can be selected and freely switched.

[0003] Such eyeglasses with a light-shielding device use fingers to cover the eyeglass lens portion when necessary, and when unnecessary,
Jump up and use. Therefore, the light-shielding device is usually attached to the spectacle frame so as to be freely rotatable. Then, it is necessary to lock the lens portion with a constant holding force so that the state is maintained in at least two states, that is, a state in which the lens portion is covered and a state in which the lens portion is flipped up.

[0004] Such a rotating device is disclosed, for example, in Japanese Utility Model Laid-Open Publication No. 2-51316, registered utility model 30261.
Something like No. 91 has been developed. These use a so-called hinge as a rotating mechanism, and the hinge screw must be strongly tightened in order to maintain the flipped up state and the covered state.

[0005] However, if the screw is strongly tightened, the screw becomes loose during use, and for example, it is not possible to maintain the flip-up state. Further, when removing the light-shielding device from the eyeglass body, it is necessary to remove the screw with a tool, which is extremely troublesome. In order to solve such a drawback, a rotating device that does not use a hinge mechanism has been proposed.

[0006] For example, the flip-up type eyeglass part of Registered Utility Model No. 3026191 has a front frame lens rotatably mounted by inserting a rotary shaft into a rotary bearing. In the spectacles, a concave portion is provided in the bearing to stop the jumped-up front frame lens.

However, since the rotating parts are fitted into the recesses by using the elastic force of the leaf spring material connecting the two front frame lenses, the elastic force of the leaf spring material once fitted. The state is locked by force. To remove it in the opposite way, the leaf spring material must be stretched. In addition, there is a limit in extending the leaf spring material, and there is a case where the rotating shaft does not come off from the bearing.

Further, for example, when the front frame is changed from a state in which the front frame is flipped up to a state in which it is used (covered state), it is necessary to apply a force against the spring force of the leaf spring material. For this reason, when the lens is flipped up from the state of covering the lens or vice versa, the force to push up the lens is relatively strong each time. Lacks.

[0009]

The present invention has been developed based on such a technical background. That is, an object of the present invention is to provide a rotating device for selecting and holding a front hanging frame at a plurality of angular positions with respect to an eyeglass frame, and a further object is to smoothly move the front hanging frame to an appropriate angular position.
