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. The structure is for temporarily fixing the two plate-shaped members, and includes an engaging tongue protruding from the corner of one plate-shaped member and an engaging protrusion protruding from the base of the engaging tongue. and a notch hole formed in the corner of the other plate-shaped member to correspond to the shape of the engagement tongue, and a notch hole formed near the corner of the other plate-shaped member, and the engagement tongue at the tip. It is characterized by comprising a leaf spring-like engagement tongue piece formed so that the protrusion can engage with it.

(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 engagement tongue protruding from the corner portion 2 of one of the plate-shaped members 1, and in the illustrated example, it is formed by punching. 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 in a flat plate, and the remaining piece is made to protrude outward by the thickness of the plate. It is formed by

Reference numeral 7 denotes a notch hole formed in the corner portion 4 to correspond to the shape of the engaging tongue piece 5, into which the engaging tongue piece 5 is fitted.

Reference numeral 8 denotes a plate spring-like engaging tongue piece formed near the corner portion 4, and the engaging protrusion 6 can be engaged with the tip 8a of the tongue piece. It is formed by providing a notch hole 9 in the shape of a square.

In the illustrated example, the engaging tongue piece 5 and the engaging protrusion are formed on one plate member 1, and the notch hole 7 and the engaging tongue piece 8 are formed on the other plate member 3. Of course, the opposite may also be true.

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 notch 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 notch hole 7, the engaging protrusion 6 presses the engaging tongue piece 8 outward a little, and then the leaf spring effect causes the engaging tongue piece 5 to fit into the notch hole 7. It will be engaged accurately, front and back,
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.

(Effect of the invention) According to the temporary fixing structure of the plate-like member according to the invention,
When attaching a sub-panel to a frame, etc., one plate-like member and the other plate-like member, each having a corner part, are overlapped at the corner part and temporarily fixed. an engaging tongue protruding from the corner of the other plate-like member; an engaging projection protruding from the base of the engaging tongue; and an engaging tongue protruding from the corner of the other plate-like member. a notch hole formed to correspond to the shape of the other plate-shaped member, and a leaf spring-like engagement member formed near the corner of the other plate-shaped member so that the above-mentioned engagement protrusion can engage with the tip. Because it is composed of tongue pieces,
Both plate-like members can be easily assembled by simply inserting the engaging tongue piece into the notch hole.

In particular, by fitting the engaging tongue into the notch hole and engaging the engaging protrusion with the tip of the engaging tongue, both plate-like members can be accurately temporarily fastened, unlike the conventional method. There is no need for temporary screws, etc., which reduces the number of parts such as screws, and even when later installation work such as screws is performed by a robot, there is no positional shift, so it can be assembled accurately. can.
