Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a structure of an eyeglass frame.

[0002]

[Prior art]

 Conventionally, a spectacle frame is made by connecting a lens frame and an arm with a hinge so that the arm can be opened and closed. The hinges used in spectacles are much smaller than the hinges used in other fields, such as the small size, the large force required to apply the size, and the smooth opening and closing feeling. Is made.

[0003]

[Problems to be solved by the device]

 As mentioned above, the hinge of the spectacles is one of the high-priced spectacle parts that requires particularly high precision. It is difficult to reduce the weight because the strength must be considered in terms of weight.

The weight of the hinge itself is small, but the weight of the hinge is also great in an eyeglass frame that is extremely lightweight, such as eyeglasses that have hollow pipe-shaped parts such as metal rims, bridges, and temples. It is desirable to make it as small as possible.

[0005]

[Means for Solving the Problems]

 The present invention is to make eyeglasses without using hinges. However, simply removing the hinges causes inconveniences such as the inability to fold the glasses. Therefore, in the present invention, the arm and the spectacle frame are detachably fitted. In addition, the lens is fixed to the frame so that the lens does not come off the frame when removed.

[0006]

[Embodiment of device]

 FIG. 1 is a view showing an example of a spectacle frame of the present invention. The threaded insertion part 3 provided at the end of the arm 2 of the spectacles is screwed into the fitting hole 4 on the spectacle frame side to be fixed. FIG. 2 shows a fitted state.

As shown in FIG. 3, by providing corresponding convex portions 8 and concave portions 9 on the contact surface where the eyeglass frame and the arm are fitted, the fixed position can be fixed.

FIG. 4 is a diagram showing another example of fitting. The movable pin 12 provided in the insertion portion 14 is fitted and fixed in the hole 11 after fitting.

FIG. 5 is a view showing another embodiment of the fitting of the present invention. As shown in FIG. 6, it is inserted and then rotated to be fixed.

In the above example, the arm and the spectacle frame are directly fitted and fixed, but as shown in FIGS. 7 and 8, they may be fixed by interposing the intermediate fixing member 20.

[0011]

[Effect of device]

 As described above, according to the spectacle frame of the present invention, there is an effect that a hinge is not required, the weight can be reduced, and the cost can be reduced. Also, if you prepare multiple arms, you can freely combine and design.
