Description

[Detailed description of the invention] [Industrial application field] This invention includes an upright female threaded portion having an outer diameter smaller than the through hole of the pad base and a height lower than the thickness of the pad base, at the pad base mounting portion. The present invention relates to a fixing structure between a spectacle frame and a pad, in which the thread length of the spectacle frame is lengthened by screwing a screw into the female threaded portion, thereby eliminating loosening of the pad due to adjustment of the pad.

[Conventional technology]

Brazing or screwing are methods for fixing eyeglass frames and pads. Screwing is used for materials that cannot be brazed, and a known method is shown in FIG. 2. That is, the pad base attachment part 11 is recessed on the back surface of the eyeglass frame 1, a screw hole 12 is bored in the pad base attachment part 11, and a through hole 22 is bored in the pad base 21. and,
By abutting the pad base 21 against the pad base attachment part 11, passing the screw 3 through the through hole 22, and screwing it into the screw hole 12, the glasses frame 1 and the pad 2 are assembled.
It is something that fixes. Padded base mounting part 1
The reason why 1 is recessed is to improve the appearance.

[Problem that the invention attempts to solve]

In this prior art, the thickness of the eyeglass frame 1 is limited in order to reduce its weight and thickness, and since the pad base mounting portion 11 is recessed, the height of the screw hole 12 into which the screw 3 is screwed is That is, the thread length is not sufficient, and therefore, when the pad 2 is adjusted, the screw 3 easily loosens, causing the pad 2 to become loose.

This invention was made for the purpose of solving the problems of such technology.

[Means for solving problems]

Means for solving the above problems will be explained below using FIG. 1 corresponding to the embodiment. In this invention, a pad base 21 is brought into contact with a pad base mounting portion 11 recessed in the eyeglass frame 1, and a screw 3 is attached to the pad base 21.
In the eyeglass frame and pad fixing structure in which the eyeglass frame 1 and the pad 2 are fixed by passing the eyeglass frame 1 and the pad 2 through a through hole 22 drilled in the pad base 21 and screwing into the screw hole 12 drilled in the pad base attachment part 11, A female threaded part 4 having an outer diameter smaller than the through hole 22 and a height lower than the thickness of the pad base 21 is provided upright in the pad base mounting part 11, and a screw 3 is screwed into the female threaded part 4 as well.

[Effect]

In such a structure, the screw 3
The length of the screw thread of the eyeglass frame 1 into which the eyeglass frame 1 is screwed becomes longer, and the adhesion between the eyeglass frame 1 and the pad 2 becomes stronger.

〔Example〕

FIG. 1 is a diagram showing an embodiment of this invention. In FIG. 1, 1 is an eyeglass frame, 2 is a pad, 3 is a screw, and 4 is a female thread.

The female threaded portion 4 is provided upright on the pad base mounting portion 11, and its outer diameter is smaller than the through hole 22 bored in the pad base 21 of the pad 2, and its height is formed to be slightly lower than the thickness of the pad base 21. There is.

Protrusion of female thread part 4 and padded base mounting part 1
1 is formed by molding the eyeglass frame 1 with a metal mold, and the screw hole 12 and the female threaded portion 4 are formed by cutting the thread after drilling the hole.

Insert the through hole 22 into the female threaded part 4, touch the pad base 21 to the pad base mounting part 11, and then tighten the screw 3.
By screwing into the female threaded portion 4 and the screw hole 12, the eyeglass frame 1 and pad 2 are fixed. Since the thread length of the eyeglass frame 1 into which the screw 3 is screwed becomes longer by the length of the female thread 4, the adhesion between the eyeglass frame 1 and the pad 2 becomes stronger.
Adjustment of the pad 2 prevents the screw 3 from becoming easily loosened.

[Effect of idea]

As explained above, this invention has an upright female threaded part in the pad base mounting part, the outer diameter of which is smaller than the through hole of the pad base, and the height of which is lower than the thickness of the pad base, and the female threaded part is also threaded. It's screwed in. Therefore, the thread length of the eyeglass frame into which the screw is screwed becomes longer, and the adhesion between the eyeglass frame and the pad becomes stronger. Therefore,
According to this invention, the screw can be easily loosened by adjusting the pad, and the effect that the pad will not come loose can be obtained.

Claims (1)

[Scope of utility model registration request] The pad base is brought into contact with the pad base attachment part recessed in the eyeglass frame, and a screw is passed through the through hole drilled in the pad base and screwed into the screw hole drilled in the pad base attachment part, thereby attaching the eyeglass frame to the eyeglass frame. In the fixing structure of the eyeglass frame and the pad for fixing the pad, a female threaded portion having an outer diameter smaller than the through hole and a height lower than the thickness of the pad base is provided in the pad base mounting portion, and the female thread portion A fixing structure for glasses frames and pads, characterized in that the above-mentioned screws are screwed in.
