Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an eyeglass pad arm for attaching a pad to an eyeglass frame.

``Prior art'' A conventional eyeglass pad arm is attached to a box-shaped pad support member in which a recess is formed into which the pad attachment part is inserted, and to an eyeglass frame that is fixed to the top surface of this pad support member with silver solder or the like. It consisted of an arm that could be

For this reason, there is no problem if the metal material can be firmly fixed to the pad support member and arm with silver solder, but if the material is titanium or titanium alloy, the pad support member and arm can be firmly fixed with silver solder. Even if the arms were brazed together, there was a drawback that the silver brazed parts came off when the glasses were assembled, and the pad support members came off from the arms. For this reason, there are many defective products, resulting in high costs, and the glasses frames in which the pad support members have fallen off are considered to be defective products, which is disadvantageous in that they are uneconomical.

``Purpose of the present invention'' In view of the above-mentioned drawbacks of the conventional technology, the present invention provides a method for reliably fixing the pad support member and the arm, even when using titanium or titanium alloy, which is difficult to securely fix using silver brazing. To obtain a pad arm for spectacles which can surely prevent a pad support member from falling off the arm and becoming a defective product when assembling a spectacle frame.

"Means for Achieving the Object of the Present Invention" The present invention provides a box-shaped pad support member in which a recess into which a pad attachment piece is inserted is formed, and a recess formed in the upper wall of the pad support member communicates with the inside of the recess. and a fixing part at one end that is inserted into the recess of the pad support member through the communication hole, crushed against the bottom surface of the pad support member with a press or the like, and fixed by spot welding or the like. It is characterized by having an arm that can be rotated.

"Embodiments of the present invention" The present invention will be described in detail below with reference to embodiments shown in the drawings.

In the embodiments shown in FIGS. 1 to 9, 1 is a box-shaped pad support member in which a recess 4 is formed into which the mounting piece 3 of the pad 2 is inserted, and this pad support member 1 is made of titanium, titanium alloy, etc. A pad support member main body 5 formed in a box shape from a metal material, a communication hole 7 formed in the upper wall surface 6 on the bottom side of the pad support member main body 5 and communicating with the inside of the recess 4, and both side wall surfaces 8, 9. Screw insertion holes 10 and screws 11 formed in
and a screw hole 12 that is screwed into the screw hole 12.

13 is an arm attached to the pad support member 1, and this arm 13 is made of titanium, titanium alloy,
An end of an arm 13 made of other metal material, one end of which is inserted into the recess 4 through the communication hole 7 of the pad support member 1, as shown in FIGS. 6 and 7. As shown in FIG. 8, a fixing portion 14 in the shape of the bottom of the pad support member 1 is formed by pressing it using a press or the like.

The fixing part 14 and the pad support member 1 are fixed by spot welding as shown in FIG. Thirteen parts are brazed and fixed with silver solders 15.

In the eyeglass pad arm 16 having the above structure, the tip of the arm 13 is inserted into the recess 4 through the communication hole 7 of the pad support member 1 and crushed by a press or the like to form the fixing part 14. The pad support member 1 and the pad support member 1 will not come off and fall off.

"Different Embodiments of the Present Invention" Next, different embodiments of the present invention shown in FIGS. 10 to 13 will be described. In the description of these embodiments, the same components as those of the embodiments of the present invention will be designated by the same reference numerals and redundant explanations will be omitted.

The embodiment shown in FIGS. 10 and 11 is mainly different from the embodiment of the present invention in that a communication hole 7 is formed approximately in the center of the upper wall surface 6 of the pad support member 1; There is an inclined surface 1 on the bottom side of 7.
7 is formed. By configuring the eyeglass pad arm 16A in this manner, the eyeglass pad arm 16A can have a shape in which the arm 13 protrudes from the upper surface of the approximately central portion of the pad support member 1.

The main difference between the embodiments shown in FIGS. 12 and 13 from the embodiments shown in FIGS. 10 and 11 is that the brazed portion is removed, and the eyeglass pad arm 16B is configured in this way. Also good.

In addition, in the above embodiment, the fixed part 14 of the arm 13
Although it has been described that the pad support member 1 is fixed to the bottom wall surface of the pad support member 1 by spot welding, the present invention is not limited to this, and the pad support member 1 may be fixed by brazing with silver solder or the like.

Further, in the embodiment of the present invention, the arm 13 is formed of a round bar and the communication hole 7 is formed of a round hole. The hole may have the same polygonal shape as . In this case, the fixing portion of the arm and the bottom wall surface of the pad support member can be sufficiently fixed without spot welding.

Furthermore, as shown by the imaginary lines in FIGS. 12 and 13, by forming a flange portion 18 on the arm 13 that contacts the upper wall surface 6 of the pad support member 1, the arm 13 and the pad support member 1 can be connected to each other. Silver brazing becomes unnecessary.

"Effects of the Present Invention" As is clear from the above explanation, the present invention has the following effects.

(1) A box-shaped pad support member, a communication hole that communicates with the inside of the recess formed on the upper wall surface of the pad support member, and a pad that is inserted into the recess of the pad support member through the communication hole, and the insertion portion is pressed, etc. It consists of an arm that can be attached to the eyeglass frame and has a fixing part that can be crushed and fixed by spot welding, etc., so it can be used even when using titanium or titanium alloy, which cannot be fixed securely with silver solder as in the past. , it is possible to reliably prevent the pad support member and the arm from coming off. Therefore, it is possible to efficiently prevent the pad support member from falling off the arm and becoming a defective product when assembling the eyeglass frame as in the conventional case.

(2) According to (1) above, the arm and pad support member are fixed by crushing the arm with a press or the like, and by spot welding or the like to fix the crushed part of the arm and the bottom wall surface of the pad support member. The work is simple, and even non-skilled workers can manufacture the product without producing defective products.

(3) Due to (1) and (2) above, it can be manufactured at low cost.
