Abstract

PURPOSE:To make it possible to fix a display board by inserting its lower side part without adhesion so that three-dimensional assembly is made possible by providing stand plates with top grooves which intersect perpendicularly with top folding lines at the centers of the stand plates and have the same width as the thickness of the display board and adequate length. CONSTITUTION:The angle at which a bottom edge 8 and a circumferential edge 11 come into contact is slightly notched in the top folding line direction and is formed as a detaining groove 12. The front end of the detaining groove 12 is positioned on the circumferential edge of a supporting piece and is formed as an insertion piece 13 by drawing a circumference of 90 deg. in a side face 4 direction around the intersected point of a bottom folding line 5 and a hinge part 7. The other side face 4 is formed to the same shape as the shape of the supporting piece 9 without having a top recessed part 10 emerging to the side face 4 from the bottom folding line 5 and is formed as a bottom piece 14. A bottom mold 15 is formed by a notch shifting the bottom folding line 5 partially toward the top folding line 3 by as much as the thickness of the strand plate 1 at the intersected point of the bottom edge 8 and the bottom folding line 5. The center of the stand plate 1 is intersected perpendicularly with the top folding line 3, by which a top groove 16 having the same size as the size of the display board 2 and the adequate length is formed. The assembled stand plates 1 are lined up and the display board 1 are fixed thereto by inserting the board into the top grooves 16.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board stand in which a display board is inserted and fixed so that it can stand on its own.

[0002]

2. Description of the Related Art A conventional board stand has an inverted T-shape, but the material is plastic.
Also, the corrugated board is fixed by adhesion.

[0003]

[Problems to be Solved by the Invention] Since there is a problem in the disposal of plastic materials and the shape is three-dimensional,
The storage was tedious. The method of adhesively fixing with glue requires time and labor for applying the glue, and this time and effort affect the cost.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention assembles a flat sheet into an inverted T shape so that a central vertical plate can be firmly set and fixed. A method that allows one part of the bottom surface to be bent and locked and fixed is used.

It is composed of a horizontally long rectangular stand plate and a main part of a display board, and a fold line is provided vertically through the center of the stand plate, and a bottom fold line parallel to the fold line is provided to both left and right regions. The bottom surface of the support piece is provided on one side surface and the side surface, and the supporting piece is provided in a shape similar to a semicircle via the hinge part that extends at the right angle to the bottom fold line and extends toward the bottom surface. It is formed as a circular edge by gradually shifting to the inside of the supporting piece toward the base of the supporting piece, and the end of the circular edge is slightly cut in the direction of the fold line to form a locking groove, and the top recess of the supporting piece is formed. To provide. The other side surface is provided as a bottom piece in the same shape as the protruding shape of the support piece 9 to the side surface. A groove is formed in the center of the stand plate in a direction perpendicular to the folding line with an appropriate length to provide a ceiling groove.

[0006]

[Function] By providing the top folding line and the bottom folding line, the stand plate can be assembled in a shape in which the letter T is inverted. Place the support piece on the bottom piece and fold the support piece to fit it into the recess of the top recess with the circular edges aligned and slide, and if the support piece stands upright, it will be fixed at the locking groove. It Since the support piece is bent and fixed, the side surface and the support piece intersect at a right angle, so the side surface is prevented from falling to the left and right. By providing the top groove, the lower side of the display board can be inserted and fixed.

EXAMPLE The present invention is manufactured by using thick cardboard or corrugated cardboard as a raw material.

An embodiment will be described with reference to the drawings. In FIG. 1, it is composed of a horizontally long rectangular stand plate 1 and a main part of a freely designed display board 2. The stand plates 1 are provided in pairs. In some cases, the shape may be designed so as not to impair the strength. In the stand plate 1, the mountain fold line that runs vertically through the center is the fold line 3
If the stand plate 1 is thick, the thickness region 17 may be provided and sandwiched between the folding lines 3. Both side areas with the top fold line 3 interposed therebetween are provided as side surfaces 4, and a bottom surface 6 is provided on a lateral end area of the side surface 4 with a bottom fold line 5 being a valley fold line. On one side surface 4 and the bottom surface 6, a supporting piece 9 is provided in a semicircular shape with a hinge portion 7 which is a valley fold line extending at right angles to the bottom fold line 5 and extending in the direction of the bottom surface 6. Is provided as a bottom edge 8 by protruding to the side surface 4, and the top of the support piece 9 is recessed to provide a top recess 10. The edge extending from the top recess 10 to the end of the bottom edge 8 is the bottom edge 8. The circular edges 11 are provided so as to be slightly shifted toward the inside of the support piece 9 toward the inside, and the corners at which the bottom edge 8 and the circular edges 11 contact each other are slightly cut in the direction of the fold line to provide locking grooves 12. The tip of the locking groove 12 is located on the circumference of the support piece, and is provided as an insertion piece 13 by drawing a circle of 90 degrees in the direction of the side surface 4 around the intersection of the bottom folding line 5 and the hinge portion 7. . Bottom fold line 5 on the other side 4
Is provided as a bottom piece 14 having the same shape as the support piece 9 having no top recess 10 extending from the side surface 4 to the side surface 4, and the bottom folding line 5 is partially formed in the stand plate 1 at the intersection region of the bottom edge 8 and the bottom folding line 5. The bottom groove 15 is provided by cutting in a direction shifted in the direction of the fold line 3 by the thickness. The center of the stand plate 1 intersects the fold line 3 at a right angle, and has the same size as the display board 2 and an appropriate length.
6 is provided.

[0009]

The effect of the present invention will be described with reference to the drawings. In FIG. 2, the top fold line 3 is mountain-folded, the bottom fold line 5 is valley-folded, and the support piece 9 is placed on the bottom piece 14. Bottom 6
When the two are brought close to each other, the insertion piece 13 is inserted into the bottom groove 15, so that they are lightly fixed.

In FIG. 3, when the state where the bottom surfaces 6 are attached to each other is viewed from the front side, the shape of the letter T is inverted, and when the support piece 9 is folded up in this state, the top recess 10 is formed. If the support pieces 9 are vertically set by sliding the circles 11 with the similar edges 11 stacked on each other, the apex recesses 10 are engaged with the engagement grooves 12
It fits in and is locked and fixed. When the support piece 9 is upright, the surfaces of the support piece 9 and the side surfaces 4 intersect each other at a right angle, which prevents the side surface 4 from falling to the left and right.

In FIG. 4, by assembling the assembled stand plates 1 in pairs and inserting the display board 2 into the top groove 16,
The display board 2 can stand on its own.
