Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a structure for temporarily fixing plate-shaped members such as frames and sub-panels having corner portions, which are component parts of audio products and the like.

(Prior art) Generally, when fitting a sub-panel etc. to a frame of a chassis etc. and securing it with screws, there is no optimal structure for temporarily securing the fitted state of the two in audio products etc., for example. However, when screwing with an automatic screw-fastening device, the screw holes may be misaligned and cannot be fixed properly.

Conventionally, as shown in FIG. 1, an engagement hole 23 is formed in the bent portion 22 of the upper case 21 as a structure for engaging the upper case 21 and the lower case 24, which are formed in a substantially U-shaped cross section. At the same time, it has been proposed that the lower case 24 is formed with an engaging tongue piece 25 corresponding to the engaging hole 23 so that the two engage with each other, and both cases 21 and 24 are secured with screws.

However, in the above-mentioned case, in the temporarily fixed state before screwing, the engagement tongue piece 25 is simply inserted into the engagement hole 23, so there may be play in both the cases 21 and 24. In extreme cases, the engagement tongue piece 25 may come off and both cases 2
1 and 24 do not engage with each other, and thus cannot be used as is as a temporary fixing means for the above-mentioned casing.

(Purpose of the invention) The purpose of the invention is to eliminate the above-mentioned conventional drawbacks,
It is an object of the present invention to provide a temporary fixing structure for a plate-like member that can easily and accurately temporarily fix the plate-like member.

(Structure of the invention) The temporary fixing structure of the plate-like members of the present invention is such that when attaching a sub-panel to a frame, one plate-like member and the other plate-like member, each having a corner part, are overlapped at the corner part. and a structure for temporarily fixing the same, which includes an engaging tongue formed at a corner of one of the plate-shaped members, and an engaging protrusion formed at the base of the engaging tongue. and an insertion hole formed by squeezing the corner of the other plate-shaped member and having a guide taper corresponding to the shape of the engagement tongue; It is characterized in that it is formed near the corner and includes a leaf spring-like engagement tongue piece formed at the tip so that the engagement protrusion can be engaged therewith.

(Embodiment) An embodiment of the present invention will be described based on FIGS. 2 to 4. In the figures, 1 is one plate member having a corner portion 2, and in the illustrated example, a frame such as a chassis is used. It is shown. 3 is the one plate member 1
The other plate-shaped member has a corner part 4 to be attached to the frame 1, and a sub-panel to be fitted to the frame 1 is shown, and this corner part 4 is the outer surface of the corner part 2 of the one plate-shaped member 1. It is polymerized and attached to.

Reference numeral 5 designates a tapered engaging tongue piece formed on the corner portion 2, and in the illustrated example, it is formed by punching and bending a flat plate.

Reference numeral 6 denotes an engagement protrusion formed at the base of the engagement tongue piece 5, and in the illustrated example, a U-shaped notch is formed on the plate surface, and the remaining piece is made to protrude by the thickness of the plate. It is formed by bending.

Reference numeral 7 denotes an insertion hole formed in the corner portion 4 through which the engaging tongue piece 5 can be inserted, and on the left side thereof, the corner portion 4 is squeezed to have the shape of the engaging tongue piece 5. A corresponding guide taper portion 8 is formed.

Reference numeral 9 denotes a plate spring-like engaging tongue piece formed by punching near the corner portion 4, and is formed so that the engaging protrusion 6 can engage with its tip 9a.

In the illustrated example, the engagement tongue piece 5 and the engagement protrusion are formed on one plate member 1, and the insertion hole 7 and the engagement tongue piece 9 are formed on the other plate member 3, respectively.
Of course, this may be reversed.

Next, temporary fixing of one plate member 1 and the other plate member 3 will be explained.

The right side surface 10 of one plate-like member 1 is aligned with the inner surface of the right side surface 11 of the other plate-like member 3 so that the engaging tongue piece 5 faces the insertion hole 7, and then the one plate-like member 1 are brought into sliding contact in the left direction, and the corner part 2 of one plate-like member 1 is connected to the corner part 4 of the other plate-like member 3.
When the engaging tongue piece 5 is overlapped with the inner surface of the guide taper part 8 and inserted into the insertion hole 7, the engaging protrusion 6 presses the engaging tongue piece 9 outward. , due to its plate spring effect, the engagement tongue piece 9
It will engage properly with the tip 9a of the front and rear,
Temporary fixing can be performed accurately without causing play in the horizontal and vertical directions.

Therefore, only in the above-mentioned temporarily fixed state, positional deviation between one plate-like member 1 and the other plate-like member 3 is prevented,
There is no risk of positional deviation occurring during subsequent work such as screw fixing.

(Effects of the invention) According to the temporary fixing structure of plate-like members of the invention, when attaching a sub-panel to a frame, etc.
A structure for overlapping one plate-like member and the other plate-like member, each having a corner part, at the corner part and temporarily fixing them, the structure being formed at the corner part of one plate-like member. The engaging tongue piece, the engaging protrusion formed at the base of the engaging tongue piece, and the corner part of the other plate-shaped member are formed by squeezing the corner part, and the above-mentioned engaging tongue piece an insertion hole having a guide taper corresponding to the shape of the plate spring-shaped plate formed near the corner of the other plate-shaped member, the tip of which can be engaged with the engagement protrusion; Since the plate-like members are composed of the engaging tongue pieces, both plate-like members can be easily assembled by simply inserting the engaging tongue pieces into the insertion holes.

In particular, by tightly fitting the above-mentioned engagement tongue into the notch, it is possible to accurately temporarily fasten both plate-like members, eliminating the need for screws, etc. for temporary fastening as in the past, and parts such as screws. The number of parts can be reduced, and even when later installation work such as screw fixing is performed by a robot, there is no positional shift, so it can be assembled accurately.
