Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a blank panel that is attached to an opening provided in a case of an electrical device or the like.

(Prior Art) Conventionally, as shown in FIG. 3, a blank panel 5 provided with a pair of elastic legs 4 having claw portions 3 is fitted into an opening 2 formed in a part of an equipment case 1. I found something to install.

(Problem to be solved by the invention) However, the distance between the back surface of the blank panel 5 and the claw portion 3 is usually slightly larger than the thickness of the opening 2; For equipment cases 1 with different thicknesses, separate blank panels 5 are used.
Since the number of parts has to be prepared, the problem is that the number of parts increases, the effectiveness of mass production is reduced, and management costs increase, resulting in higher costs.

(Means for Solving the Problems) This invention was made to solve these problems, and will be described in detail below based on embodiments shown in the drawings.

The blank panel 10, as shown in FIG.
A pair of U-shaped frames 11 on the back surface, and a plurality of elastic legs 14a, 14b having different lengths, for example, two elastic legs 14a and 14b, which extend from the intermediate connection part 12 of the U-shaped frames 11 while gradually increasing the wall thickness, It is integrally molded from synthetic resin. The tips 15a and 15b of the elastic legs 14 have a wall thickness large enough to protrude outward from the U-shaped frame 11, and the distance between these tips 15 and the back surface of the panel 10 is equal to the distance between the tips 15a and 15b of the long elastic legs. It is short at 14a and becomes long at short elastic legs 14b. The short elastic leg 14b has its tip 1
The wall thickness from 5b onward becomes slightly smaller, and the tip part 1
It extends to almost the same length as 5b. As shown by the dotted line, the long elastic legs 14a and the short elastic legs 14b are of the same type and are arranged diagonally facing each other, that is, they are arranged symmetrically so that the connecting line passes through the center. The intermediate connecting portion 12 of the U-shaped frame 11 is formed thin in order to provide elasticity to the elastic legs 14. A thin recess 16 is formed on the back surface of the blank panel 10 in order to give the panel a slight elasticity as a whole and to hang the panel 10 when it is removed. The device case 17 has an opening 1 large enough to surround the outside of the U-shaped frame 11.
8 is provided. The wall thickness of this opening 18 is
As shown in FIG. 2, the distance between the elastic legs 14 and the back surface of the panel 10 is slightly reduced.

(Function) It is configured like this, and the blank panel 1
When the frame 11 of 0 is inserted into the opening, the elastic legs 1
When the back side of the panel 10 comes into contact with the surface of the device case 17 while the elastic legs 4 are being pushed inward, the elastic legs 14 are restored to their original state, and the periphery of the opening 18 is sandwiched between the tip 15 and the panel 10. In rare cases, the blank panel 10 is attached to the equipment case 17.
At this time, if the wall thickness around the opening 18 is large, the short elastic leg 14b is used, and if it is small, the long elastic leg 14a is used. By providing three or more elastic legs 14 and having different lengths to the tips 15, the blank panel 10 can be easily attached by simply inserting them into openings 18 having three or more different wall thicknesses. Since the elastic legs 14 having the same length up to the tip end 15 are arranged symmetrically, the panel 10 can be securely mounted and held in a well-balanced manner. When removing the blank panel 10 once installed, insert the tip of a tool (not shown) such as a screwdriver into the recess and apply a force to pull it up.The panel 10 will bend slightly and will not engage with the elastic legs 14. The combination is resolved.

(Effects of the invention) As mentioned above, according to this invention, even if the thickness of the opening of the device case differs, it can be easily installed by simply inserting a common blank panel, reducing the number of parts and the management cost. , an excellent effect can be obtained in that costs can be reduced due to mass production effects.
