Description

[Detailed explanation of the invention] (a) Industrial application field This invention relates to a wagon, specifically a wagon used for display purposes at stores such as department stores and supermarkets.

(b) Prior Art In this type of wagon, it is desirable that the size of the mounting table can be freely changed depending on the amount of exhibits.

(c) Problems to be solved by the invention However, in conventional wagons, the area of the mounting table cannot be changed in size, or cannot be changed smoothly.

(d) Means for solving the problem This invention consists of a rectangular frame and a guide rail that is fixed on two parallel sides of the rectangular frame with a gap provided between them and the upper surface of the rectangular frame. The spherical surface is biased upward on the upper surface of the rectangular frame, and the two parallel sides are hollow bodies that can fit into the guide rail. The wagon is characterized by comprising a movable frame forming a plurality of spherical fittable recesses at appropriate positions, a mounting plate placed on the movable frame, and legs vertically disposed at the bottom of the rectangular frame. By providing this, we will solve the problems of the conventional technology.

(E) Function Fit the moving frame from the end of the guide rail, and move the moving frame toward the center of the rectangular frame. Then, among the plurality of recesses provided in the movable frame, the recess on the most central side of the rectangular frame, that is, on the front end side of the movable frame, fits into the spherical surface.

In this state, the surface on which the wagon can be placed is the largest is obtained. Then, a mounting surface is placed on this surface.
If a smaller mounting surface is desired, the mounting plate is removed once and the movable frame is further moved toward the center of the rectangular frame. Then, among the plurality of recesses provided in the moving frame, the spherical surface fits into the hole located on the inner side of the most distal end. In this state, a smaller mounting surface is obtained. A mounting plate is placed on this mounting surface.

By sequentially performing such operations, a wagon mounting surface having a desired area is obtained.

(F) Embodiment The following is a first example showing a front view of an embodiment of this invention.
Fig. 2 shows a plan view of the same, Fig. 3 shows a partial enlargement of Fig. 1, Fig. 4 shows a parts diagram, Fig. 5 shows a state of use, and Fig. 6 shows an outline of a state of use. Explain according to c.

1 is a square frame. As is clear from FIG. 2, in this embodiment, the rectangular frame 1 has long sides of approximately
It consists of a nearly rectangular frame with a width of 900 mm and a short side of approximately 700 mm.
Formed by welding square pipes on each side. 2 is a guide rail. The guide rails 2 each consist of a square pipe with a length approximately equal to the long side of the square frame 1, and are parallel to the square frame 1 with a gap of l ₁ between them and the top surface of the square frame 1, as shown in FIG. Fix it on the long side. A shelf is erected on the guide rail 2 with a gap provided between it and the upper surface of the guide rail. A sphere 3 is welded and fixed to the tip of the guide rail 2.

A spherical surface 4 biased upward by a spring is installed at an appropriate position on the upper surface of the frame below the installation position of the guide rail 2. In this embodiment, a total of four pieces are installed near each end of the long side of the rectangular frame 1 at equal distances from each end. The spherical surface 4 may be entirely spherical as a whole, or may be hemispherical with only the upper surface spherical.

Reference numeral 5 designates moving frames, each of which has a substantially U-shape in plan view, as shown in FIG. The two opposing parallel sides of the moving frame 5 are hollow rectangular pipes with a rectangular cross section that can be fitted with the guide rail 2, and the lower surface of the side that fits with the guide rail 2 has a hole shape as shown in Fig. 3. A recess 6 is formed. In this embodiment, recesses 6 are formed on each parallel side of each movable frame 5 at intervals of approximately 150 mm. A shelf separate from the shelf on the guide rail 2 is erected on the movable frame 5 along the U-shaped frame. A horizontal bar 7 is passed between opposing parallel sides of the moving frame. Reference numeral 8 denotes a mounting plate, which is substantially rectangular in plan and has a locking portion 9 facing downward at the end thereof as shown in FIG. The locking portion 9 is formed by fixing a square piece over the entire width of the mounting plate or by fixing it to a part of the mounting plate.

The mounting plate 8 has two bending parts, and when it is bent at both places, when it is bent at only one place,
By choosing not to bend it at all and then bending it, it is possible to have three different sizes: 900 mm, 1200 mm, and 1500 mm in total length. The mounting plate 8 may be composed of three separate plates. Numeral 10 denotes legs, which are hung from the four corners of the rectangular frame 1. The lower parts of the legs 10 are fixed by two horizontal bars parallel to the short sides of the rectangular frame 1, and can be bent parallel to the long sides of the rectangular frame 1 from the bending parts 11 and 11'. . The bent portions 11 and 11' each have a rectangular frame 1.
Since the distances from the bottom surface are different, it can be folded as shown in Figure 4, and does not take up much space when stored.

Further, by extending a horizontal bar across the lower part of the leg 10 parallel to the long side of the rectangular frame 1, positioning during use is performed. Three of the four sides formed between the legs 10 can be covered with sheets or the like.

Therefore, the ends of the moving frames 5, 5 having the rectangular openings are fitted to each end of the guide rail 2,
Slide toward the center of the square frame 1. Since the sphere 3 is fixed to the tip of the guide rail 2, fitting is easy, and even if the pressing direction at the time of sliding is oblique, the inner surface of the movable frame 5 hits the sphere 3, and the movable frame becomes a relief. It is possible to correct the direction of 5. When the moving frame is pressed toward the center, the spherical surface 4 fits into the first recess 6. This positioning makes it possible to set the area that will be the largest on the loading surface of the wagon.

In this example, the width is 1500 mm. Then, when each movable frame 5 is further pressed toward the center, the spherical surface 4 fits into the next hole. With this positioning, the next widest mounting surface is set. In this example the width is approx.
It is 1200mm. When pressed further, the spherical surface 4 fits into the last hole, and this positioning results in the narrowest mounting surface. The width is approximately 900 mm in this example. At each installation position, the mounting plate 8 can be folded or unfolded according to its dimensions, and one or both of the locking parts 9 can be used to lock the horizontal bar as shown in FIGS. A mounting surface is formed by locking or simply placing it on.

Therefore, this invention makes it possible to provide a wagon whose mounting surface can be changed smoothly and easily.
