Description

[Detailed description of the invention] This invention relates to a display stand in which shelf-supporting posts are erected on a base plate and several shelves are supported on the posts, and while the erected posts can be tilted to be roughly parallel to the base plate, they are reliably maintained in an erect position when erected, and can be folded up by a simple operation, so that the posts that hold them up can be flattened for easy handling when transporting the display stand or when storing it away when not in use.

To explain this invention by way of an example, as shown in Fig. 1, the display stand has columns 2, 2 erected from the rear of both sides of a base plate 1 formed in a rectangular shape. The pillars 2, 2 are connected by several horizontal bars 3 to form a frame shape, and the pillars 2 and horizontal bars 3 are hollow and have a rectangular cross section like a square pipe. Therefore, as shown in FIG. 2, a plate-shaped connecting plate 4 is fixed to the outer surface of the lower end of the support column 2 (referring to the surface opposite to the opposing inner surfaces of both support columns 2, 2) by welding. At the same time, the lower part of the connecting plate 4 is provided so as to further protrude from the pillar 2, and the lower part of the connecting plate 4 protruding from the pillar 2 has a main elongated hole 5 that is long in the vertical direction within the plate surface, and the connecting plate 4 A sub-elongated hole 6, which is also long in the vertical direction, is provided by cutting out and opening from the lower end of the
Moreover, the main elongated hole 5 of both the parallel main and sub elongated holes 5 and 6
is longer than the sub-elongated hole 6, and the main elongated hole 5 is provided in the front part of the connecting plate 4, and the sub-elongated hole 6 is provided in the rear part, that is, at intervals. The main pin 7 protruding from the side surface of the base plate 1 is engaged with the main elongated hole 5 of the connecting plate 4, and the base plate
A support post 2 is attached to the base plate 1.
The support 2 is made upright from the base plate 1 by engaging the sub pin 8 protruding from the side surface of the connecting plate 4 with the sub elongated hole 6 of the connecting plate 4. When the support 2 is upright, both the main and sub pins 7 and 8 It is arranged to be located at the upper end of the main and sub-elongated holes 5 and 6, and when the support column 2 is pulled upward, the sub-pin 8 escapes from the sub-elongated hole 6, and the main pin 7 is placed in the main elongated hole 5. It is formed so as to be located at the lower end.

Incidentally, the connecting plate 4 is provided with a protrusion 9, and when the support column 2 is in an upright state, the protrusion 9 comes into contact with the base plate 1 to stabilize the upright state of the support column 2. Further, a stop portion 10, which is formed by bending a band plate in a U-shape and engages into the support 2, is protrudingly provided at a portion of the base plate 1 where the support 2 stands. Also, base plate 1
A leg 11 is provided on the back side of the holder, and the leg 11 may be a nut as shown in the figure or a caster.

As is clear from the above, this idea is based on the base plate 1.
In this display stand, a pair of columns 2, 2 are erected at the rear of both sides of the base plate 1, and a display shelf is constructed between these columns. A sub-pin 8 is provided protruding rearward and downward, while main and sub-elongated holes 5, 6 are provided on the opposite side of the column 2 to engage with the pins 7, 8.
A plate-shaped connecting plate 4 with The main elongated hole 5 is formed in the vertical direction within the plate surface of the connecting plate, and the sub-elongated hole 6 is opened by cutting out the lower end of the connecting plate in the vertical direction, and the main pin 7 is formed in the main length. The auxiliary pin 8 and the auxiliary long hole 6 are removably engaged with each other while maintaining the state of engagement with the hole 5, so that the column can be erected and folded, and the erected column 2 In case of defeating
First, the support column 2 is pulled up perpendicularly above the base plate 1. The sub-pin 8 is pulled out from the sub-elongated hole 6 by the pulling operation, and since the connecting plate 4 is engaged only with the main pin 7, the sub-elongated hole 6 is separated from the sub-pin 8 with the main pin 7 as the center of the support 2. By rotating the support column 2 in the direction shown in FIG. Next, when raising the folded column 2, by rotating the column 2 in the direction in which it is raised, the secondary pin 8 engages in the secondary elongated hole 6, and both the main and secondary pins 7, 8 spaced apart are engaged. The pillar 2 holds it upright.

Note that the protrusion 9 of the connecting plate 4 comes into contact with the top of the base plate 1, making the upright state of the column 2 more stable, and if the base plate 1 is provided with a stop 10, the stop 10 is provided inside the column 2. The stabilization of the column 2 is further strengthened by the engagement of the portion 10.

As described above, the display stand according to this invention supports the support column with a pair of front and rear pins on the base plate, and
The engagement relationship with one of the pins is designed to be able to be fitted and removed freely, which simplifies the support structure for the support column to the base plate.Furthermore, when folding the column, the column is pulled up, and when standing up, the structure is simple. Since the can be held upright simply by rotating it so as to raise the support, folding and raising operations are extremely easy. In addition, when using a prop upright, there is no force being applied to pull it up unless you intentionally apply force to pull it up; on the contrary, a load is constantly being applied to push it downwards, so it is difficult to use it. There is no risk that the support column will fall down accidentally, which can improve safety.

Claims (1)

[Scope of utility model registration request] A display stand is provided with a pair of support posts 2, 2 standing on the rear of both sides of a base plate 1 and a display shelf installed between these support posts. A main pin 7 and a sub-pin 8 protruding rearward and downward from the pin 7 are provided on the rear of the side of the base plate 1, while a plate-like connecting plate 4 having main and sub-long holes 5, 6 which engage with the pins 7, 8 is fixed to the side of the support post 2 opposite to the opposing sides. Furthermore, a protrusion 9 is provided on the connecting plate 4 on the side where the support post is fixed, the lower end of which is located on the same plane as the lower end of the support post.
The display stand is characterized in that the main slot 5 of the connecting plate 4 is formed vertically within the surface of the connecting plate, and the sub-slot 6 is formed by cutting out the lower end of the connecting plate vertically, and the sub-pin 8 and the sub-slot 6 are engaged freely with each other while maintaining the main pin 7 engaged with the main slot 5, thereby allowing the support to be erected and folded.
