Abstract

PROBLEM TO BE SOLVED: To mount a back supporting plate without adhering with paste. SOLUTION: The back supporting fixed structure is formed by folding and standing a folding stand plate 3 from a back standing portion 2 of a back extending area of a bottom plate 1, engaging a protruding piece 4 formed by projecting an upper part of the front surface edge of the plate 3 with an engaging hole 6 punched at a lower portion of a back plate 5 to fix the folding and standing state of the plate 3. The plate 3 operates as a supporting plate, and simultaneously prevents folding of the portion 2.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back support fixing structure for improving the sitting position by supporting and fixing the back of a thin object back and forth.

[0002]

2. Description of the Related Art In a conventional back support fixing structure, the center of a support plate is attached to the back of a back plate by gluing, and a plate piece extending on both sides is cut in the center while being folded back. The fixed plate was fixed by folding it up from above.

[0003]

The conventional product requires time and effort to adhere to the back surface. An object of the present invention is to simplify the manufacturing by eliminating the trouble of attaching to the back surface.

[0004]

Means for Solving the Problems A folded plate extending in a protruding area of a bottom plate is folded up, and a protruding piece having an upper portion of a front edge of the folded plate projecting to the front is fitted into a hook hole punched in the back plate. The upright plate acts as a support plate and improves the sitting of the back plate.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is manufactured by using a moderately thick cardboard, and the positional relationship such as front, back, front, rear, up, down, left, and right is described in terms of a mountain valley and a valley based on the front in the assembled state. The bending direction is displayed with reference to the outside.

[0006] In the rear perspective view of FIG. 1, the back region of the bottom plate 1 is a region protruding from the back plate 5 at the time of assembling. Plate 3 formed by making a similar T-shaped notch with its front facing
It is desirable to open the top edge of the outer side and fold it up, but a structure in which the folding plate 3 is extended to the side edge of the protruding area 2 and folded up from the outside to the inside may be used. ,
The upper half of the front edge of the folded plate 3 protrudes to the front to form a projecting piece 4, and the projecting piece 4 is fitted into a hooking hole 6 opened in the lower part of the back plate 5, so that the lower part of the projecting piece 4 becomes a hooking hole. The back plate 5 may be a single pop plate, but is preferably a box 7, and the front edge of the bottom plate 1 extends to the front lower edge of the box 7. It is desirable that it is established.

In FIG. 2 which is a rear perspective view of the completed assembly, since the box 7 is thin in the front and rear direction, it is easy to fall down in the front-rear direction. It is desirable that the back area 2 is
As it protrudes further to the back, it supports it to fall backward, and the folding plate 3 extended to the protruding area 2 is folded up at a right angle, and the projection 4
Is inserted into the hook hole 6 and hooked, whereby the folded-up state of the folding plate 3 is fixed. When the folding plate 3 is folded, the folding plate 3 serves as a support plate, and at the same time, the protruding area 2 To prevent bending.

In FIG. 3 which is a front perspective view of the completed assembly, the shape of the insertion box 7 is such that a side plate 8 extending on both sides of the back plate 5 is bent out to the front, and the side plate 8 is formed by cutting off the upper front corner of a vertically long rectangle. The front edges of side plates 8 having a pair at both sides are connected by a front plate 9, and the height of the front plate 9 is basically a horizontally long rectangle that is clearly lower than the back plate 5, and the front plate 9 is horizontally long. The bottom plate 1 may be extended through a mountain fold line at the lower edge of the front plate 9, and may be formed into a designed shape. The bottom plate 1 is fixed by the projection pieces 4 being peeped out and hooked.

In FIG. 4 which is a developed plan view, FIG. 4 is shown from the outside, and the positional relationship such as up, down, left and right is shown in FIG.
Is displayed only on the basis of the state described in the drawing, a side plate 8 is provided on both sides of the back plate 5 via a mountain fold line, and a front plate 9 is provided on one side edge of one side plate 8 via a mountain fold line. The bottom plate 1 is extended from the lower edge of the front plate 9 to the lower edge of the front plate 9 via a mountain fold line, and the lower half region of the bottom plate 1 is defined as a protruding region 2. Cut out the folded plate 3 by making a cut in the shape, the lateral outer edge of the folded plate 3 is extended to the protruding area 2 through the valley fold line, and the inner half of the top edge of the folded plate 3 is appropriately upward (front direction). ) To form a protruding piece 4, and punch out a hooking hole 6 in the lower part of the back plate 5 in a vertically long rectangle with rounded corners.

[0010]

According to the present invention, since the back region formed by extending the back of the bottom plate to the back extends rearward from the back plate, the back plate is prevented from falling backward, and the upright plate is formed from the back region 2. To prevent bending of the raised area, and the protruding piece formed by projecting the upper front edge of the folded plate to the front is hooked in the hook hole, so the folded state of the folded plate is fixed. At the same time, since it is attached to the back plate and also serves as a support plate, there is no need to bond the support plate to the back surface of the back plate, and manufacturing can be simplified.
