[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shelf structure provided with shelves extending over columns on both sides, and a connecting tool for selectively connecting and supporting the shelves with shelf connecting portions juxtaposed on the columns.

[0002]

[Prior art]

 Conventionally, in the above-described shelf structure, when an intermediate shelf 2'is provided above or below the original shelf 1 which extends over the columns 6 on both sides, the intermediate shelf 2'extends over the columns 6 on both sides as shown in FIG. As to the size of the original shelf 1, both ends of the shelf 1 are selectively connected and supported by the connecting tools 5 to the shelf connecting portions 8 of the columns 6 on both sides.

[0003]

[Problems to be solved by the device]

 However, in the above-mentioned conventional structure, by selecting the connection target of the middle shelf 2'from among the shelf connecting portions 8 juxtaposed on each of the columns 6, the middle shelf 2'and the upper and lower shelves 1 are connected. Although it is possible to adjust the vertical spacing between the two, the installation of the intermediate shelf 2 reduces the vertical spacing between the intermediate shelf 2'and the shelves 1 placed above and below it to the same size over the entire width between the columns, so the size is large or small. When storing various items, it becomes difficult to store large items, and conversely, if the support height of the intermediate shelf 2'is selected according to large items, the space between the upper and lower shelves can be adjusted to accommodate small items. There was a waste of space, and there was a case where the original purpose of attachment of the intermediate shelf, which tried to use the space as effectively as possible, could not be fully achieved.

An object of the present invention is to enhance the accommodation of large and small articles and to make more efficient use of space by a rational intermediate shelf structure.

[Means for Solving the Problems]

 A characteristic structure of a shelf structure according to the present invention is that a shelf extending over both columns is provided, and a connecting tool for selectively connecting and supporting the shelves to a shelf connecting portion arranged side by side on the supporting column is provided. Intermediate shelves having a size smaller than the space between them are vertically arranged with respect to the shelves, and an intermediate shelf support for supporting one end side of the intermediate shelf is provided. One end side of the intermediate shelf is supported for the intermediate shelf. Is selectively connected and supported by a connecting tool to the shelf connecting parts arranged side by side, and the other end side of the intermediate shelf is selectively connected and supported by a connecting tool to the shelf connecting part on one of the columns. In particular, the action and effect are as follows.

[0006]

[Action]

 That is, according to the above-mentioned characteristic configuration, the connection target of the middle shelf is selected from the shelf connection parts of one of the columns, and in accordance with it, the connection target of the intermediate shelf is selected from the shelf connection parts of the column for intermediate shelves. By selecting and connecting and supporting intermediate shelves to the selected shelving joints with connecting tools, intermediate shelves with dimensions smaller than the spacing between the columns on both sides, that is, intermediate shelves shorter than the original shelves can be selected. It can be installed at a desired height and with sufficient support strength by supporting both ends, and the vertical dimension that does not receive vertical division by the intermediate shelf on the side of the columns on the side opposite to the side connecting the intermediate shelves Can secure a large storage space.

[0007]

[Effect of device]

 Therefore, according to the present invention, a large article can be easily accommodated without being restricted by the intermediate shelf, and the height of the intermediate shelf can be appropriately selected to store a small article with little waste space. Compared with conventional products, the storage capacity for large and small items has been greatly improved, and the space can be used more effectively.

【Example】

 Next, examples will be described.

As shown in FIG. 1, in a shelf structure in which main shelves 1 having a large frontage dimension are arranged side by side in the vertical direction, an intermediate shelf 2 having a frontage dimension smaller than that of the main shelves 1 is arranged at one side in the frontage direction. It is provided between the main shelves 1 and by attaching the intermediate shelves 2, various sizes of articles can be efficiently accommodated and stored in space.

Each of the main shelves 1 and the intermediate shelves 2 has a placement surface portion a formed by assembling the linear materials 3 in a lattice shape, and is also formed of the linear material 4 around the placement surface portion a. The frame portion b is integrally attached, and the main shelf 1 is fixedly supported by connecting the four corners to the four main columns 6 by the connecting tools 5.

As for the intermediate shelf 2, two corners on one side in the frontage direction are connected to two main columns 6 on the same side by a connecting tool 5, and two corners on the other side are lower main shelves. The two intermediate shelf columns 7 that are erected at 1 are connected and fixedly supported by a connecting tool 5.

On each of the main support column 6 and the intermediate shelf support column 7, an annular groove 8 is provided as a shelf connection portion side by side at a predetermined interval in the longitudinal direction of the support column. As shown in FIG. 2 and FIG. 3, an annular protrusion 9 that engages with the annular groove 8 of the columns 6 and 7 is formed on the inner peripheral side, and is formed in a half-divided structure with the cylinder axis direction as the cutting direction. It comprises a stop cylinder 10, a holding cylinder 11 fitted on the locking cylinder 10, and a shelf-side cylinder 12 attached to each of the four corners of the shelves 1 and 2.

The locking cylinder 10 has an outer peripheral surface formed as a taper peripheral surface having a reduced diameter on the upper side, and a collar-shaped projection 10a for receiving the lower end of the holding cylinder 11 fitted on the outer peripheral surface is formed at the lower end portion on the outer peripheral side. In addition, the holding cylinder 11 has an inner peripheral surface formed on the outer peripheral taper peripheral surface of the locking cylinder 10 such that the outer peripheral surface thereof is closely fitted to the outer peripheral tapered peripheral surface, and the outer peripheral surface is also formed on the outer peripheral tapered peripheral surface. The shelf-side cylinder 12 is formed on the taper peripheral surface with an upper diameter reduced so that the inner peripheral surface of the shelf-side cylinder 12 is closely fitted to the outer peripheral tapered peripheral surface of the holding cylinder 11.

That is, a rack connecting object is selected from the plurality of annular grooves 8 in each of the columns 6 and 7, and the annular projection 9 of the locking cylinder 10 is engaged with the selected annular groove 8 by half. The locking cylinder 10 having a split structure is externally fitted to each of the struts 6 and 7, and in this state, the holding cylinder 11 is dropped in the supporting column inserted state to be closely fitted to the locking cylinder 10. Thus, by engaging the annular groove 8 and the annular protrusion 9 with each other, fitting the tapered peripheral surfaces together, and locking the flange-shaped protrusion 10a with respect to the holding cylinder 11, the locking cylinder 10 and the holding cylinder 11 are respectively attached to the columns 6, 6. It is fixedly attached to 7.
