DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises an upright support, and a bracket for connecting an article mounting member for mounting an article to the support, and extending along a longitudinal direction of the support. By inserting a connector through one of a plurality of support-side mounting holes provided at equal pitch or substantially equal pitch and a bracket-side mounting hole provided in the bracket, The present invention relates to a connection structure of an article placing member connected and fixed to a support.

[0002]

2. Description of the Related Art Such a connecting structure of article placing members is implemented, for example, when assembling an article placing shelf for an automatic warehouse. Since the height is various, it is preferable that the height of the article mounting member connected and fixed to the column can be set or changed at a pitch as short as possible. Therefore, conventionally, a plurality of pillar-side mounting holes are provided at equal pitches or substantially at equal pitches along the longitudinal direction of the pillar, and further, along the pillar-side mounting holes, the pitch is shifted by 、, and the same pitch is used. By providing one of the plurality of support-side mounting holes, selecting one of the two columns of support-side mounting holes, and inserting and locking one locking portion provided on the bracket in the selected support-side mounting hole. There has been proposed a structure in which the height of the article mounting member can be set by changing the position up and down at a pitch of の of the pitch between the mounting holes on the support side (for example, Japanese Patent Application Laid-Open No. Hei 6-1).
No. 15641).

[0003]

However, in the prior art described in the above-mentioned publication, the pitch is reduced to 1/2 for one support.
Although a plurality of support side mounting holes are provided in two rows in a shifted state, since there is only one locking portion on the bracket side, the article mounting member can be mounted only by selecting the support side mounting hole provided in the support. If the pitch is to be set or changed, and if the pitch is to be shortened, the number of support-side mounting holes provided in the support will increase, and the strength of the support will increase as the number of support-side mounting holes increases. There was a problem of lowering.

The present invention has been made to overcome the above-mentioned drawbacks, and an object of the present invention is to reduce the number of mounting holes provided in a column to prevent the strength of the column from being reduced, and to mount articles at a pitch as short as possible. An object of the present invention is to provide a connection structure of an article placing member that can set and change the height of the placing member.

[0005]

In order to achieve this object, according to the first aspect of the present invention, a plurality of bracket-side mounting holes are provided in the bracket along the longitudinal direction of the column, and the plurality of mounting holes are provided. Since the pitch between the bracket-side mounting holes is different from the pitch between the support-side mounting holes, any one of a plurality of support-side mounting holes provided at an equal pitch or substantially equal pitch along the longitudinal direction of the support is used. In response to this, a plurality of bracket-side mounting holes are selected and made to correspond to each other, and the article mounting member is connected and fixed by inserting a connecting member across both of the corresponding mounting holes, so that the column-side mounting holes are separated. The height of the article placing member can be set and changed at a pitch shorter than the pitch of the member. As a result, despite the fact that the height of the article mounting member can be set and changed at a relatively short pitch, the number of support-side mounting holes provided in the support can be minimized to avoid a decrease in the strength of the support. .

According to the second aspect of the present invention, the pitch between the mounting holes on the bracket side is shorter than the pitch between the mounting holes on the support side, so that the article mounting member is set at a desired height and the support columns are set at a desired height. When connecting and fixing to the article mounting member, the final height can be set by first selecting the bracket-side mounting hole having a relatively long pitch and selecting the bracket-side mounting hole having a short pitch. The operation for connecting and fixing the object at a desired height is simplified, and the article placing member can be easily and reliably connected and fixed at the desired height.

According to the third aspect of the present invention, the pitch between the mounting holes on the bracket side is configured to be an integral multiple of the pitch between the mounting holes on the bracket side. In the state where the connecting member is connected and fixed at a desired height and another article mounting member is connected and fixed at a desired distance above or below the space between the two article mounting members, Is easy to set, and a plurality of article mounting members can be connected and fixed at a desired interval according to a relatively simplified procedure.

According to the fourth aspect of the present invention, the number of mounting holes on the bracket side is configured to be the same as an integer multiple of the integer, so that the length of the bracket along the longitudinal direction of the column is determined by the length of the column. The pitch between the side mounting holes can be made shorter, and the bracket can be made as short as possible.

According to the fifth aspect of the present invention, the bracket is formed in an L-shaped cross section including a front plate for applying the bracket to the front surface of the column and a horizontal plate for applying the side surface to the side on which the article exists. Therefore, for example, the bracket can be easily applied to the column as compared with a configuration in which the cross section of the bracket has a U-shape and the column is held from the lateral side. Then, a through hole is provided in the front plate, a notch hole is provided in the horizontal plate on the side opposite to the front plate, a bracket-side mounting hole is formed by the through hole and the notch hole, and a connecting pin is provided. A bent portion and a straight portion are formed in a substantially L-shape, and the bent portion penetrates and engages with a notch hole of the horizontal plate, and the straight portion has a support-side mounting hole provided in a support and a front plate. , The front plate and the horizontal plate are strongly applied to the column, despite the bracket having the L-shaped cross section. The bracket can be firmly connected to the column.

[0010] According to the invention described in claim 6, the support column has four columns.
The main body is erected, and the brackets are connectable to both ends of the article mounting member, and the brackets connectable to both ends are connected and fixed to two opposing columns. The placing member is firmly connected between the two columns, and various articles can be placed and stored using the pair of article placing members connected between the two columns.

According to the seventh aspect of the present invention, the support is a support constituting an article storage shelf for an automatic warehouse, and the article mounting member is an article storage shelf to be stored in the automatic warehouse. From, in an automatic warehouse that stores various articles of various sizes, as described above, it is possible to change the height of the article mounting member at the shortest possible pitch while avoiding a decrease in the strength of the support, It is possible to provide an optimal shelf for an automatic warehouse.
