Description

DETAILED DESCRIPTION OF THE INVENTION This invention is formed by mounting several article storage boxes each containing each product on a rotating frame that is rotatably provided on a base via a horizontal axis. The present invention relates to a rotating display stand for sales in which products can be selected and taken out by rotating a rotating frame by hand.

Each item storage box in the above-mentioned rotating display stand is usually attached to the rotating frame with both ends supported by shafts, and is kept horizontal by the center of gravity of the storage box itself, so each item storage box is The box sways, making it inconvenient to select and take out products, and the arrangement of the products inside shifts, changing the center of gravity, resulting in the storage box always being tilted.

In contrast, in this invention, a subwheel is provided on the rotating frame with the fulcrum position shifted, and the subwheel and the article storage box support shaft of the rotating frame are linked to form a parallel link mechanism, so that they are parallel to each other. Each article storage box is always held in a horizontal state via each link.

Before describing the embodiments of the present invention, the outline of the present invention will be briefly explained with reference to the explanatory sectional view shown in FIG. A horizontal shaft with a bent height difference is fixed, and several article storage boxes 7 are installed on the high side 4b of the horizontal shaft 4, with the circumference equally divided between the front and rear main wheels 5, 6. A basket-shaped rotating frame 8 suspending the auxiliary wheels 9 is inserted into and supported by the lower side 4a of the horizontal shaft 4 along one of the main wheels 5, and the periphery of the main wheel 5 and the periphery of the auxiliary wheel 9 are supported. are connected by several links 10..., and one end of these links is fixed to one end surface of the article storage box 7 via a shaft. With this configuration, when the rotating frame 8 is rotated, each link 10 tilts while keeping parallel to each other, and the article storage box 7 integrated with the axis of each link is always maintained horizontally. It will be done. In this case, the positions of the centers of the rotating frame 8 and the secondary wheel 9 are not limited to those shown in FIG. Since protruding in the opposite direction is disadvantageous in terms of selection and removal of articles as well as appearance, it is actually determined as shown in the figure.

Next, an embodiment of the present invention will be explained with reference to FIGS. 2 to 6. In FIGS. The wire frame is covered with a net 11 to serve as a cover. As is clear from FIGS. 1 and 5, one end of the lower side 4a of the horizontal shaft 4 is fixed to the front base frame 2, and the horizontal shaft 4 is fixed to the rear base frame 3.
The end of the high side 4b is supported. This horizontal shaft 4 is made of a single piece of material, with a high side 4b and a low side 4b.
A may be formed, but in practice, one end is fixed to the front base frame 2 and the other end of the lower side 4a is made into a rectangular cross section as shown in FIGS. 5A and 5B. A connecting plate 12 having a rectangular hole at the lower end is fitted therein and fastened with a nut 13, and the upper side 4b is fixed to the upper end of the connecting plate 12.

The rotating frame 8 is integrally made by arranging straight rods in a cross shape through the center of a circular frame, and connecting front and rear main wheels 5 and 6 with bearings at the center by a horizontal pipe 14. , 6, there are a plurality of article storage boxes 7, eight in the figure, whose circumferential edges are equally divided. In this case, the base end of the shaft 15 fitted into the front main wheel 5 is fixed to the upper end of the link 10.
The lower end of is connected to the peripheral edge of the subwheel 9 via a shaft 17. Furthermore, the tip of the support shaft 15 and the article storage box 7
As is clear from FIGS. 6A and 6B, the top edge of the support shaft 15 is formed into a square cross section, and
A mounting plate 18 having a square hole and a mounting plate 19 having a round hole are fitted to this with the front plate of the article storage box 7 sandwiched therebetween, and are fixed by tightening with nuts 20 .

The subwheel 9 is made to have the same size and structure as the main shafts 5 and 6, and is fitted with its center bearing hole fitted to the lower side 4a of the horizontal shaft 4, and is fitted into eight holes opened on its periphery. The shafts 17 are fitted into each other.

As described above, each article storage box 7 is attached so that its front surface spans the front main wheel 5 and the subwheel 9, and the top surface of the box body is orthogonal to the link 10. However, the rear surface is supported by simply inserting the support shaft 16 into the rear main wheel 6,
Further, the rear main wheel 6 is also directly supported by the rear base frame 3.

In addition, in Fig. 4, 21... is the rear base frame 3.
It is a uniform board installed using the outer surface of the. Moreover, the article storage boxes 7 are net boxes that are open at the top and long in the front and back direction, and as shown in FIG. 3, every other box has a round bottom or a flat bottom depending on the type of article.

This invention has the above-mentioned structure, and the rotating frame 8 is manually rotated to sequentially raise and lower the required article storage boxes 7, just like a normal rotating display stand. As described above, by using the parallel crank mechanism, each article storage box 7 is always maintained in a horizontal state and does not swing, so there is no problem in selecting and taking out articles, and there is no problem in storing articles. Since there is no need to consider the position of the center of gravity of the article storage box, there are many advantages such as freedom in displaying and arranging articles (commodities).
