Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shelf device having a leg device at its lower part, such as a frame shelf for an automated warehouse or a frame shelf with a slide table.

[0002]

2. Description of the Related Art Conventionally, as this type of shelving device, a structure disclosed in, for example, Japanese Patent Laid-Open No. 2-33013 has been provided. In this conventional configuration, the shelf is composed of columns and horizontal members, and a seating member is detachably attached to the lower end of the columns. The seating member includes a base plate, a side plate body and a front plate body that are erected on the base plate by welding and abut against the outer surface of the column, and a nut member fixed to the lower surface of the base plate by welding.
An adjusting tool for level adjustment is composed of a fixed plate and a bolt member rotatably erected on the fixed plate and screwed to the nut member.

According to this conventional structure, with the fixing plate fixed to the floor surface, the bolt member is screwed onto the nut member to connect the seating member to the adjusting tool, and the seating member is connected to the lower end portion of the column. It is used by connecting with a rivet. Then, the bolt member is rotated through a nut attached to the bolt member, and the relative position of the bolt member and the nut member is displaced in the vertical direction, thereby adjusting the level of the column with respect to the floor surface.

[0004]

In the above-mentioned conventional structure, since the adjusting member has the bolt member rotatably erected on the fixed plate, the adjusting device is capable of performing stable rotation while supporting the shelf. Requires a complicated and highly precise support structure, which is not easy to manufacture and is expensive. It is also proposed to fix the nut member on the fixing plate by welding in order to support the rotation, but in this case, the fixing plate and the nut member are easily deformed due to welding distortion, and the bolt member rotates. Difficult to see, and moreover, the weld is exposed, which makes it unattractive. Further, since the coating process is started after welding, the paint adheres to the screw holes of the nut member, which makes it difficult for the bolt member to rotate.

An object of the present invention is to provide a shelving device which is easy to manufacture and can be coated easily, and can be suitably screwed and rotated for adjusting a level.

[0006]

In order to achieve the above object, a shelf device according to the first aspect of the present invention has a landing body having vertical through holes, a large diameter large cylindrical portion and a small diameter small cylindrical portion. A leg device is composed of a connecting body and a connecting rod that can be screwed into the connecting body, and the connecting body is formed by inserting the small diameter cylindrical portion into the through hole from above and then caulking the lower end in the radial direction. It is formed so as to be fixable to the landing body, and its central hole is formed in a screw hole, and the connecting rod has an operating portion in the middle and a screw portion that can be screwed into the screw hole below the operating portion. It is formed so that the upper portion of the operation portion can be connected to the lower portion of the shelf portion.

The shelf device according to the second aspect of the present invention further comprises a landing body having through holes formed in the vertical direction, a connecting body having an upper large diameter tubular portion and a lower diameter small tubular portion, and can be screwed into the connecting body. The connecting body is formed by inserting the small diameter tubular portion into the through hole from above and then caulking the lower end in the radial direction to be fixed to the landing body, and the central hole portion of the connecting body. The connecting rod is formed in a screw hole, and an operating portion is formed in the middle, and screw portions in opposite directions are formed on both upper and lower sides of the operating portion, and the lower screw portion is configured to be screwed into the screw hole. The upper screw portion is configured to be screwed into the screw portion formed on the lower portion of the shelf.

[0008]

According to the structure of the first aspect of the present invention, since the connecting body can be caulked after the landing body is painted, only the connecting body can be plated. The connecting body can firmly connect to the landing body without welding by sandwiching the landing body by the small diameter tubular portion and the large diameter tubular portion crimped in the radial direction. Further, the connection with the shelf can be performed by rotating the connecting rod through the operation part to screw the screw part into the screw hole, and then connecting the upper part of the connecting rod to the shelf part. The level of the shelf with respect to the floor can be adjusted by rotating the unit.

Further, according to the structure of the second aspect of the present invention, the connection with the shelf portion can be performed by screwing the upper screw portion of the connecting rod into the screw portion on the shelf portion side, and the level adjustment is performed via the operation portion. By rotating the connecting rod, the simultaneous expansion and contraction action can be performed both above and below the operating portion.
