Description

[Detailed description of the invention] Purpose of the invention Industrial application field This invention can be stacked to provide the required shelf height difference when in use, and can be stored compactly when not in use, saving storage and transportation space. This relates to stackable shelves that can be stacked.
Widely used for office applications such as filing cabinets, household applications such as accessory shelves, commercial applications such as pamphlet displays, industrial applications such as parts shelves, and agricultural applications such as culture shelves for installing mushroom culture bags. can do.

BACKGROUND ART Conventionally used shelves with a large number of tiers are mainly made of wood or metal and have a fixed structure. Products with such a structure have fixed spaces between the shelves, so they occupy a large space for transportation, storage, and display.

There is also an assembly method that uses a metal frame with many mounting holes and a shelf board, but it takes time and effort to assemble, and it is not easy to disassemble and store when not in use.

Problems to be Solved by the Invention This invention is a stackable shelf that can be stacked to provide the required shelf level difference when in use, and can be stored compactly when not in use, saving storage and transportation space. The purpose is to provide a stage.

Means for solving the structural problems of the invention That is, the invention includes a shelf board, a leg-shaped lower side piece with an open bottom attached to both sides of the shelf board,
It consists of a raised hand-shaped upper side piece with an open top attached to the upper outer side of the lower side piece, and a frame having left and right side edges and front and rear edges attached to the upper outer side of the upper side piece. It has a structure in which the front and rear ends of the shelf boards of the shelf can be engaged and fixed to the front and rear edges of the frame, respectively.

This will be explained in detail with reference to the accompanying drawings. FIG. 1 is a partial perspective view of an example of the present invention, in which a leg-shaped lower side piece 2 with an open bottom is attached to the side surface of a shelf board 1. The lower side piece 2 may be attached directly to the side of the shelf, but in order to easily store other shelves of the same shape without friction when not in use, such as during storage or transportation, it is recommended to attach the lower side piece 2 to the side of the shelf as shown in the figure. It is preferable to install a spacer 3 between the shelf board 1 and the lower side piece 2 so that the lower side piece 2 slightly (about several millimeters) overhangs the shelf board 1.

An upper hand-shaped upper side piece 4 with an open upper part is attached to the upper outer side of the lower side piece. As for the shape of the upper side piece, it is preferable from a design point of view to have a symmetrical shape with the lower side piece upside down as shown in the figure, but the shape is not necessarily limited to a symmetrical shape from a functional point of view.

Furthermore, a frame 5 having left and right side edges and front and rear edges is attached to the upper upper side of the upper side piece. Since FIG. 1 is a partial view, only the left side edge 5A and front edge 5B are shown, but a right side edge 5C and a rear edge 5D are similarly provided on the opposite side.

The left and right side edges 5A and 5C of the frame may be attached directly to the upper outer side of the upper side piece 4,
As in the case between the shelf board 1 and the lower side piece 2, it is preferable to provide a spacer 7 and attach the frame so that the left and right side edges slightly (about several millimeters) overhang the upper side piece 4.

Furthermore, in the example shown in this figure, the front and rear lengths of the shelf board and the front and rear lengths of the frame 5 are made the same size,
The front and rear ends of the shelves of other shelves of the same shape (the shelves of the second shelf placed on top of the first shelf) can be placed and held on the front and rear edges of the frame. It's like this. If you simply place it on the shelf, there is a risk that the upper shelf will shift and fall due to contact or vibration, so in Figure 1, the length of the front edge 5B of the frame corresponding to the width of the shelf is the thickness of the shelf. A lower portion 5b is provided, and the structure is such that a shelf plate of another shelf having the same shape can be fitted into the lower portion 5b to be engaged and fixed. A similar portion 5d is provided on the rear edge 5D of the frame (see FIG. 4). A stopper 8 is provided near the front and rear ends of the shelf board to prevent the shelf board of the upper shelf fitted into the frame of the lower shelf from moving back and forth.

The structure in which the front and rear ends of the shelves of other shelves of the same shape are engaged and fixed to the front and rear edges of the frame, respectively, is not limited to the one shown in Fig. 1; The front and rear lengths of the shelves are shorter than the front and rear lengths of the frame, and the hooks are attached to the front and rear of the shelf to engage the frame of the lower shelf. An appropriate structure can be selected in consideration of the purpose of use and design effect, such as a structure in which the shelf is made longer than the length of the shelf board and placed on the frame of the lower shelf, and a stopper is provided at the bottom of the shelf board.

Furthermore, the shapes of the lower side piece and the upper side piece are not limited to those illustrated in FIG. 1. For example, as shown in FIG. But that's fine. In this case, since there is no wasted space in the overlapping portion with the side piece of another shelf above or below when storing, the shelf can be stored in a more compact state. Alternatively, it may be a combination of arcuate shapes as shown in FIG. Further, the horizontal bar having the shape (ladder shape) shown in FIG. 1 may be even longer. Either can be selected by considering the purpose of use and design effect.

At least one side piece is required for each side wall. Even if there is only one, it is connected to the shelf board and frame at two points, so there is no problem with stability. It is free to provide a plurality of them in consideration of the strength required to support the weight placed on the shelf board and the design effect.

The shelf board is not limited to a single board as shown in FIG. 1, but can be shaped into a grid, net, etc. depending on the purpose of use.

The shelf of the present invention can be made of any material such as wood, plastic, metal, round metal bar, etc. depending on the purpose of use.

FIG. 4 shows a plan view of the shelf according to the present invention shown in FIG. 1, FIG. 5 shows a side view thereof, and FIG. 6 shows a front view thereof.

Operation: Figure 7 shows the three shelves of the present invention stacked one above the other and ready for use.
When the side pieces having the shape shown in FIG. 1 are used, a hexagonal pattern appears on the side surface when used stacked in this way.

On the other hand, in order to reduce the space occupied during storage and transportation, the 8th
As shown in the figure. To store, lift the upper shelf slightly to disengage it, shift it back by the width of the frame, and lower it slightly downwards, then move the shelf of the upper shelf to the frame of the lower shelf. When the lower side pieces are passed through and lowered directly below, the lower side pieces overlap each other, and the upper side pieces overlap each other, as shown in FIG. 8, and are stored in a compact state.

FIG. 9 shows the mutual positional relationship of the two shelves while they are being stored. In this invention, the side piece that makes up the side wall is divided into two parts, upper and lower.
The height of the lower side piece is lower and the space between the side piece of the upper shelf and the side piece of the lower shelf when the shelf board of the upper shelf is stored by passing through the frame of the lower shelf. It has a large amount of free space and is easy to store.

Effect of the invention 1: When in use, they can be stacked to provide the required shelf level difference, and when not in use, they can be stored compactly, saving storage and transportation space.

2. A beautiful design effect can be expected depending on the shape of the side piece.
