Description

[Detailed description of the invention] The invention is applicable to, for example, cassette decks, radios,
The present invention relates to a device for fixing plate-shaped bodies to each other, which can be optimally applied when forming a back plate of a housing of an electrical device such as a television.

Conventionally, back plates for housings of electrical equipment such as cassette decks, radios, and televisions have been divided into several plate-shaped sections to facilitate repair and inspection. The plate-shaped bodies were fixed to each other so that the body could be easily removed, and the entire body was screwed to the housing body. By the way, as a means for fixing the plate-like bodies of the mounting plate and the plate to be mounted, which constitute this back plate, there is a conventional method shown in FIGS. 1 and 2.
Among these, the one shown in FIG. 1 has a mounting hole 1'a in the mounting plate 1' and inserts a stepped insertion piece 4'a formed on the mounting plate 4' into the mounting plate 4'. The plate 1' to be mounted and the mounting plate 4' were engaged and fixed. However, in the conventional fixing means employing this fixing means, the mounting hole 1'a must be molded and processed on the mounting plate 4', and the stepped insertion piece 4'a must be formed on the mounting plate 4'. When the mounting plate 4' and the mounting plate 1' are molded from casting, synthetic resin, etc., the molds are expensive. Moreover, when the mounting plate 4' is molded from sheet metal, when the stepped insert piece 4'a is bent, it is not possible to obtain the stepped insert piece 4'a with high precision.

Another conventional fixing means shown in FIG.
By providing the insertion piece 4″a that is inserted into the
Insert the insertion piece 4″a of the mounting plate 4″ into the insertion opening 3″ of the mounting plate 1″, and attach the mounting plate 4″ to the mounting plate 1″.
This is to fix the However, in both the conventional products shown in Figs. 1 and 2, the mounting plate 1',
In the direction of arrows A′ and A″ parallel to 1″, step insert piece 4′
a and the insertion piece 4''a are inserted into the mounting hole 1'a or the opening 3'' of the fixing receiving piece 2'', so the mounting direction of the mounting plate 4' with respect to the mounting plate 1' is unidirectional. For this reason, the mounting position of the mounting plate 4'' on the entire rear panel cannot be mounted in a dark position, and the mounting position is inevitably determined.

The present invention was made in view of the above points, and its purpose is to attach a fixing receiving piece formed by a wide part and a narrow part through a cut and raised piece facing the plate to which it is attached. By cutting and raising the corner part of the mounting plate into the wide part of this fixing receiving piece, the movement in the parallel direction to the plate to be mounted is restricted by the cut and raising piece, and the mounting perpendicular thereto. The movement of the plate in the thickness direction is restricted by the wide portion, and the mounting position of the mounting plate relative to the plate to be mounted is regulated and securely fixed, so that at least no attachment can be made to the plate to be mounted. Since no processing means are required, the mold is cheaper than before, and the dimensional accuracy of the mounting plate relative to the plate to which it is mounted does not need to be high. An object of the present invention is to provide a fixing device for mutually fixing plate-like bodies, which allows a mounting plate to be attached to a plate to be attached by simply inserting the corner portions of the plates not only in one direction.

A first embodiment of the present invention will be described below with reference to an embodiment shown in FIGS. 3 and 4.

Reference numeral 1 denotes a mounting plate that constitutes a back plate of a housing of an electrical device such as a cassette deck, radio, or television, and the mounting plate 1 is formed of metal or synthetic resin using a mold, for example. or by stamping and forming a metal plate. 2 is a fixing receiving piece cut and raised in a part of the mounting plate 1;
This fixing receiving piece 2 is formed of a wide part _2a and a narrow part _2b , which are bent in a direction parallel to the mounting plate 1 with a strong structure through opposing cut and raised pieces 2a 1 and 2b 1. Moreover, openings 3, 3 are formed on the left and right sides of the wide part 2a and the narrow part 2b. 4,4
is a mounting plate that is fixed to the mounting plate 1 by inserting its corner portion into the fixing receiving plate 2, and these mounting plates 4, 4 are mutually connected in a plane parallel to the mounting plate 1. Movement in the directions of arrows X and Y perpendicular to the direction of the mounting plate 1 is regulated by the cut and raised pieces 2a ₁ and 2b ₁ for positioning, and the movement in the direction of the arrow Z perpendicular to the parallel direction of the mounting plate 1, that is, the mounting plate 4 in the thickness direction is regulated by the wide portion 2a to determine the mounting position.

Since one embodiment of the present invention has the above-mentioned configuration, in order to fix the mounting plate 4 to the mounting plate 1, the width of the fixing receiving plate 2 formed on a part of the mounting plate 1 is required. The mounting plate 1 is fixed to the mounting plates 4, 4 by inserting the corner parts of the mounting plates 4, 4 into the openings 3, 3 formed on the left and right sides of the clamp part 2b and the wide part 2a. . In this case, the fixing receiving plate 2 is
Since it is formed by the wide part 2b and the wide part 2b, it can be moved in any direction of arrows A, B, and C with respect to the wide part 2a, that is, up and down, left and right, and diagonally with respect to the wide part 2a, as shown in FIG. It can be inserted from either direction. Therefore, the mounting plates 4, 4 can be easily mounted without being restricted in the position of the fixing receiving plate 2 relative to the mounting plate 1 and the direction of mounting the fixing receiving plate 2 relative to the mounting plate 4. , the area occupied by the mounting plates 4, 4 in the entire panel can be changed freely, and the mounting plate 4 itself can be assembled into cut-and-raised pieces 2a 1 , 2b by simply inserting its corners into the openings 3, ₃ of the fixing receiving pieces 2. ₁ restricts the movement in the directions of arrows X and Y parallel to the mounting plate 1, allowing the mounting plates 4, 4 to be positioned, and the wide portion 2a controls the movement in the thickness direction of the mounting plate 4.
In other words, since the mounting plates 4, 4 can be fixed to the mounting plate 1 without any fixing process such as restricting movement of the mounting plates 4 in the direction of arrow Z and determining the mounting position, the plate-shaped object etc. It can be molded into simple shapes by die-casting using castings or molds using synthetic resin. Therefore, the mold etc. can be made inexpensive without becoming complicated, which is a source of cost reduction.

Next, what is shown in FIG. 5 is a second embodiment of the present invention. In this embodiment, in order to form the fixing receiving piece 2 provided on the mounting plate 1, the wide part 2a is opposed to the wide part 2a on both sides. Width part 2 through cut and raised pieces 2b ₁ and 2b ₁
b, 2b are formed, the mounting plates 4, 4;
By inserting the corner part into the fixing receiving piece 2 from any one of the vertical, horizontal, and diagonal directions, the cut and raised pieces 2b ₁ and 2b ₁ can be inserted in the direction parallel to the mounting plate 1, that is, the arrow Mounting plates 4, 4 in the X direction;
The mounting position is determined by restricting the movement of the mounting plate 4, and the movement of the mounting plate 4 in the thickness direction, that is, the direction of the arrow Z is restricted by the wide portion 2a, and the mounting position is determined. The only difference from the previous embodiment is that four mounting plates 4, 4; 4, 4 can be attached to the plate 1 at the same time.

What is shown in FIG. 6 is a third embodiment of the present invention, and in this embodiment, the fixing receiving piece 2 provided on the mounting plate 1 is formed in four directions upward, downward, left and right with respect to the wide part 2a. Cut and raised pieces 2b ₁ , 2b ₁ ; 2
Width part 2b, 2b; 2b, 2b via b _{1 ,} 2b 1
By providing this, the corners of the mounting plates 4, 4; 4, 4 can be attached to the openings 3, 3; 3, 3, which are provided across the wide part 2a and several width parts 2b, up and down, left and right, and _movement in the directions of arrows X and Y which are parallel to and perpendicular to the mounting plate ₁ by inserting the cut and raised pieces 2b ₁ and 2b ₁ from either diagonal direction; By regulating the mounting position of the mounting plates 4, 4; 4, 4, it is possible to simultaneously mount the four mounting plates 4, 4; 4, 4 to the mounting plate 1. be.

As described above, the present invention involves cutting and raising a fixing receiving piece formed by a wide part and a wide part through a cut-and-raising piece facing the mounting plate, and attaching a mounting plate to the wide part of this fixing receiving piece. By inserting the corner part of the mounting plate, the cut-and-raised piece restricts movement in the direction parallel to the mounting plate, and the wide part restricts movement in the thickness direction of the mounting plate, allowing natural positioning of the mounting position. By doing this, it is possible to securely fix the mounting plate to the plate to which it is mounted, and at least the plate to which it is mounted does not require any attachment processing means, so the mold is smaller than before. In addition to being inexpensive, the dimensional accuracy of the mounting plate relative to the mounting plate does not need to be high, and the corner of the mounting plate is not limited to one direction with respect to the fixing plate of the mounting plate, making it easy to use. The mounting plate can be attached by inserting it into the holder.
