Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a plate attachment device for attaching a plate such as a transparent plate to the main body of wireless equipment such as a video tape recorder.

Conventional Structure and Problems In a video tape recorder as shown in FIG. 1, for example, a main body casing 1 is made of iron plate, and a relatively large transparent plate 2 is attached to the top surface. As shown in FIG. 2, the transparent plate 2 is supported by a pair of fittings 3, 3 fixed to the inner surface of the iron plate casing 1 by spot welding. Specifically, the third
As shown in the figure, L-shaped engagement pieces 3 are provided on the mounting brackets 3, 3 at appropriate intervals in correspondence with a plurality of flanges 2a protruding from both sides of the transparent plate 2 at appropriate intervals.
The transparent plate 2 has flanges 2a on both sides thereof and is supported by being sandwiched between the engaging pieces 3a and the housing 1. FIG. 4 shows the order in which the transparent plate 2 is supported, and as shown in the figure, the flange 2a of the transparent plate 2...
By pressing the transparent plate 2 against the back surface of the top plate of the casing 1 while being separated from a, and pushing the transparent plate 2 in the direction of arrow A in this state, the collar portions 2a... and the engaging pieces 3a...
are engaged with each other, and the transparent plate 2 is supported. In this case, the pitch at which the flanges 2a are attached is set in consideration of the bending strength of the transparent plate 2 itself, so that it will not be greatly dented even if the transparent plate 2 is pushed from above, but if the transparent plate 2 becomes large, The number of collar portions 2a increases. In addition, if each flange 2a is not supported by a predetermined pressing force, the transparent plate 2
The fixation becomes loose, and problems such as looseness and chatter are likely to occur. Therefore, as shown in FIG.
A certain amount of pressing force is required for each flange 2a when inserting it into the transparent plate 2a from the side, but as the number of engagement points increases, a larger pressing force is required to push the transparent plate 2, which makes product assembly difficult. This was a major hindrance to the above. Moreover, since this pushing force is applied impulsively at the initial stage of insertion of the flange portion 2a, it tends to become even more significant. That is, these impact forces may damage the transparent plate 2 or apply excessive force to the portion supporting the housing 1, resulting in damage to the appearance. In addition, the number of man-hours was uneven, making it difficult to perform stable production, and problems were likely to occur in terms of quality.

Purpose of the invention The present invention solves the above-mentioned drawbacks of the conventional technology, and makes it extremely easy to insert plates such as transparent plates.
The purpose is to rationalize productivity and to obtain finished products that have a good appearance and are of good quality.

Structure of the Invention The plate mounting device of the present invention is configured such that a plurality of flanges attached at appropriate intervals on both sides of a plate are engaged with a plurality of engagement pieces provided on the casing side, and the flanges and The engagement pieces have different pitches.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the drawings. First, a first embodiment shown in FIG. 5 will be described. In FIG. 5, 11 is a transparent plate having a plurality of flanges 11a to 11d attached at appropriate intervals on both sides, and 12 is a plurality of flanges 1 of the transparent plate 11.
A plurality of engagement pieces 12 corresponding to 1a to 11d
a to 12d are provided and are fixed to the housing by spot welding, and the plurality of flanges 11a to 11d of the transparent plate 11 are located between the engaging pieces 12a to 12d of the mounting bracket 12 and the housing. It is configured to be held between the As mentioned in the conventional example, the excessive pushing force of the transparent plate is applied at the initial stage when the flange is inserted into the engagement piece, and once it is inserted, it is supported in a predetermined position with a light pushing force. Focusing on this, as shown in FIG.
~11d pitch and engagement piece 12a of mounting bracket 12
The pitch of ~12d is made different, and the transparent plate 11
The flanges 11a to 11d and the engaging piece 1 are in the state before installation.
The gaps A to D between 2a to 12d are A<B<C<
It is designed to be D. Therefore, when a pushing force is applied to the transparent plate 11 in the direction of the arrow in FIG. 5, the flange 11a located at the front end is first inserted into the engagement piece 12a. In this case, the insertion is performed with the initial pushing force of one pair of the flange and the engaging piece. Next, the flange 11b is inserted into the engagement piece 12b, but at this time, the flange 11a is inserted into the engagement piece 12b.
The entire body moves with the reduced pushing force and the initial pushing force of the collar portion 11b. Thereafter, pushing is performed one after another, and finally, the flange 11d is engaged by the sum of the initial pushing force of the flange 11d and the reduced pushing force of the flange parts 11a to 11c, and the attachment of the transparent plate 11 is completed. In the first embodiment described above, the reduced pushing force is significantly smaller than the initial pushing force, so in reality, the flange 11a
The push-in force is sufficient to insert one set at a time in the order of 11d to 11d, and the shockingly excessive push-in force required in the conventional example is not necessary, and the assembly work is significantly improved.

The first embodiment has been described above, but as shown in FIG.
The gap between the transparent plate 11 and the transparent plate 12d may be changed every other space (E<F), and as shown in FIG.
The gap G between the flanges 11a to 11d on one side and the engaging pieces 12a to 12d of the mounting bracket 12 and the transparent plate 11
The gaps H between the flanges 11a to 11d on the other side and the engagement pieces 12a to 12d of the mounting bracket 12 may be changed, and furthermore, the gaps H between the flanges 11a to 11d on the other side and the engagement pieces 12a to 12d of the mounting bracket 12 may be changed.
You may also combine what is shown in the figure.

Effects of the invention As described above, according to the invention, the work of attaching plates such as transparent plates can be carried out with light force, and therefore the assembly jig can be simplified, thereby improving productivity. In addition, since no large force is applied when inserting the plate, there will be no scratches on the exterior of the finished product.
The quality is also good.
