Description

The present invention relates to glasses that can be flipped up.

In general, the flip-up glasses are composed of a left and right temple part, a wading part connecting the temple parts, and a movable frame part connected to the wading part by a rotation mechanism, and each movable frame is used by flipping the movable frame part to the upper front by the rotation mechanism. Adjust the focal length according to the purpose of the person.

Further, there is a flip-up type spectacle such as utility model registration No. 3121730 that can be flipped up according to the focal length to the user's object.

  Utility Model Registration No. 3121730

As described above, in the case of glasses equipped with a spring-up function by inserting a spring into the rotation mechanism, the spring-up capability is reduced due to the aging of the spring. Furthermore, the rotational movement is easily transmitted to the threaded portion, and the threaded portion is easily loosened. Therefore, it is actually very difficult to maintain the flip-up function so as to be most suitable for each user over a long period of time.

Moreover, in what is shown to patent document 1, a structure becomes complicated, the number of parts increases, and the possibility that a failure will occur increases. In addition, the number of production processes and the manufacturing unit cost associated therewith are problems.

In order to solve the above problems, in the present invention, a polygonal or elliptical recess is provided on one hinge side of both ends of the rotating mechanism, and the polygonal or elliptical head of the female screw fits into the recess. Thus, the movements of the hinges at both ends of the rotating mechanism are integrated with the movements of the female screws, and the relative reversal movement of the central hinge portion of the rotating mechanism with respect to the hinges at both ends is fastened to the female screws from the other hinge one side of the two hinges. In order not to be transmitted to the male screw, a configuration in which the female screw covers the male screw is adopted, and a configuration in which the stop angle of the movable frame part can be set steplessly by friction between the contact surfaces of the hinges on both ends and the central hinge part is adopted. doing.

If comprised as mentioned above, there will be no problem of the loosening of the screw which arises by rotating a rotation mechanism part, and the problem of reduction of the raising ability by the secular deterioration of a spring. In addition, the configuration of parts is minimal, the possibility of failure is low, and the production process is also few and can be provided at low cost. Furthermore, by adjusting the screw, the strength of the flip-up function and any desired flip-up angle can be easily set.
