Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a telescoping rack whose left and right width can be changed within a certain range.

[Conventional technology]

Generally, a rack such as a bookshelf or an article storage shelf is formed by fixing a plurality of shelf boards between the left and right walls of a rectangular frame, and the left and right width of the rack is always constant and cannot be changed. Therefore, depending on the installation location, the width of the rack may be slightly too large to allow installation, or the width of the rack may be too small, creating a dead space. Furthermore, even if the width of the rack is slightly insufficient, it may not be possible to place an article on the rack, or the article may not be stored in a predetermined orientation.

In order to solve this problem, for example, in a kitchen drainer shelf, the width of the shelf can be changed as disclosed in Japanese Utility Model Publication No. 57-20028, Japanese Utility Model Publication No. 57-29652,
This method is known from Japanese Patent No. 57-29653 and Japanese Patent No. 52-17376.

FIG. 5 shows an example of such a conventional extendable shelf (Japanese Utility Model Publication No. 57-20028). In this case, the shelf width can be changed by arranging the hollow flat plate shelf 21 and the pipe shelf 22 on the left and right, and supporting one end of the pipe shelf 22 by the side end wall of the flat plate shelf 21 so that it can be taken in and out. The left and right ends of the pipe shelf 22 are integrally fixed by connecting bars 23 and 24, respectively.

[Problem that the invention attempts to solve]

When a telescoping rack is constructed using the conventional shelf structure as described above, the following problems occur.

First, since the structure is such that a shelf in which a flat plate shelf 21 and a pipe shelf 22 are extendably connected is attached to a vertical frame, stored items are placed directly on the extendable shelf. Therefore, the load applied to the shelf boards is concentrated on the connecting points, which tends to cause early damage, and when a heavy object is placed on the shelves, the connected points tend to deform into an inverted U-shape.

Second, since conventional shelves only have the function of placing items on the shelf, it is not possible to store vertically long items such as rugs in a vertical position.

[Purpose of invention]

The present invention has been proposed in order to solve the above-mentioned problems in telescopic racks.

An object of the present invention is to provide an extendable rack that can easily adjust the width of the left and right shelves depending on the installation location.

An object of the present invention is to provide a telescoping rack with improved durability by having a structure in which weight is not concentrated at the connecting portion for telescoping.

The purpose of the present invention is to provide a telescoping rack that can hold vertically long stored items in a vertical position by utilizing the telescoping structure of the shelf, and can effectively utilize storage space without wasting it.

[Means for solving problems]

In this invention, a pair of left and right vertical frames 3L, 3R
Horizontal bars 5L and 5R are protruded from the opposite sides, and the protruding ends thereof are fitted and connected in a widthwise direction to form a rack frame 1, and when the horizontal bars 5L and 5R are stretched and deformed, the shelf board 2 is formed. is supported on horizontal bars 5L and 5R so as to be slidable in the left and right direction.

〔Example〕

1 to 4 show embodiments of the present invention.

In FIG. 3, the telescoping rack of the present invention consists of a rack frame 1 and shelf boards 2 supported by the rack frame 1 and forming upper and lower shelves.

The rack frame 1 has vertical frames 3L and 3R formed by bending tubes into a gate shape when viewed from the side, which are arranged to face each other left and right. It is connected like a child structure.

The horizontal bars 5L, 5R are formed as a front and rear pair, and this pair is fixed to two upper and lower positions of the legs 4, 4 with a vertical interval apart.

In FIG. 1, the left and right horizontal bars 5L and 5R are made by cutting steel pipes into predetermined dimensions, and fixing nuts 6 to one end of each pipe by caulking, and bolts 7 that pass through the legs 4 laterally are attached to the outside. By screwing into the nut 6 from the side, the left and right horizontal bars 5L, 5R
are supported and fixed in a cantilevered manner to the vertical frames 3L and 3R, respectively. The outer diameter of the left side crosspiece 5L is set slightly smaller than the inner diameter of the right side crosspiece 5R when facing the figure, and the left side crosspiece 5L is supported by fitting inside the right side crosspiece 5R. By setting rack frame 1
The entire area can be expanded and contracted in the left and right width directions.

It is formed by bending downward from the periphery of the horizontally long rectangular top wall 8a, which has a horizontal length slightly larger than that of the right horizontal bar 5R of the shelf board 2 and a longitudinal length larger than that between the legs 4, 4. The left and right side walls 8b, 8c and the front and rear side walls 8d, 8e form a box shape that opens downward. The left and right side walls 8b, 8c are respectively provided with crosspiece insertion holes 9, 9 at two locations on the front and rear.
By externally fitting the crosspiece insertion hole 9 of the right side wall 8c to the fixed end of the right horizontal crosspiece 5R, and externally fitting the crosspiece insertion hole 9 of the left side wall 8b to the left horizontal crosspiece 5L, both horizontal crosspieces 5L ,5
A shelf board 2 is supported with respect to R so as to be movable left and right.

The rack constructed as described above is used by pushing and pulling the left vertical frame 3L and changing the width of the left and right shelves of the rack frame as a whole depending on the installation location. For example, as shown in FIG. 4, when a drawable organizing shelf 14 is housed in the opening of the closet 13, the rack is placed in a dead space on the back side of the organizing shelf 14.

When the left horizontal frame 5L is pulled out and the shelf width is expanded and deformed, there will be a gap between the left vertical frame 3L and the shelf board 2.
A void S is formed whose front and rear sides are sandwiched between horizontal bars 5L and 5R. Utilizing this space S, as shown by the imaginary line in Fig. 3, store a vertically long stored item B such as a rug in a vertical position, and then shift the shelf board 2 laterally to connect the left side wall 8b and the vertical frame. 3L and hold the stored item B in an upright position. As a result, vertically long stored items B for which it is difficult to find a suitable storage space can be easily collected together with other items and stored in an organized manner, and storage spaces such as closets and closets can be used effectively.

[Another embodiment example]

In the present invention, some of the above embodiments may be modified as follows.

The crosspiece insertion hole 9 is formed as an inverted U-shaped groove, and the shelf board 2 can be easily attached to and removed from the horizontal crosspieces 5L and 5L as required.

In the case where the left and right horizontal bars 5L and 5R have different lengths, for example, the front right horizontal bars and the rear left horizontal bars are made of long pieces, and the connecting points are shifted left and right between the front and rear pairs. do.

[Effect of idea]

As explained above, in the telescoping rack of the present invention, the horizontal bars 5L and 5R constituting the strength member are provided with a connection structure for expansion and contraction, and the horizontal bars 5L and 5R are provided with a connecting structure for expansion and contraction.
Since the shelf board 2 is supported by the shelf board 2, it is possible to effectively eliminate the concentration of load on the connecting portion. Therefore, it is possible to effectively prevent the deformation of the shelf board 2 due to concentration of load and the inclination of the shelf board surface due to looseness in the connecting parts, and it is possible to obtain a highly durable telescoping rack with little wobbling and excellent rigidity. .

In addition, when the horizontal bars 5L and 5R are stretched and deformed, the empty space S formed between the shelf board 2 and the vertical frame 3L is used to store vertically long stored items B, and they are collected together with other items. Since the items can be organized and stored, the storage space such as a closet can be used effectively without any waste.
