Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a portal-shaped cargo handling rack used when the space above a load directly stacked on the floor is used as a support space for another load. It is about.

(Prior Art) A cargo handling rack of this type is one in which pillars are vertically connected from four corners of a rectangular rack, and a space below the cargo rack surrounded by the pillars is used to raise a floor surface. It is possible to directly load luggage on the above, and to put another luggage on the receiving tray, but when not in use, it is possible to perform so-called nesting in which the same racks are fitted to each other to reduce the bulk. There must be.

Therefore, in this type of nestable cargo handling rack, front and rear rail members are erected vertically in two steps on both left and right sides, and the lower rail member of the upper rack is placed on the upper rail member of the lower rack during nesting. Although it is configured, in the conventional rack, for example, the actual rack shovel 62-16421.
As in the rack described in Japanese Patent Publication No. 5, the lower rail member of the upper and lower two-tier rail members is used to prevent lateral shift of the upper rack during stacking. The upper rail member is composed of a flat square steel pipe that cannot be fitted inside the lower rail member (mounting steel) of the upper rack during nesting.

(Problems to be solved by the invention) In the conventional cargo handling rack as described above, only the lower rail member of the upper rack is placed on the upper rail member of the lower rack during nesting, and the left and right rail members overlap vertically. I cannot stop the lateral shift. In other words, there is a problem in that stability tends to be lost due to slippage between the upper and lower racks in the lateral direction during nesting.

(Means for Solving the Problems) In order to solve the above conventional problems, the present invention provides
From the left and right ends of the rectangular side of the cargo receiving stand, the supporting front support columns are provided in a hanging manner at the positions projecting to the left and right outside from the left and right side ends of the cargo receiving base.
A supporting rear strut is hung down continuously at a position inside the position of the supporting front strut, and a front end is located between the supporting front strut and the supporting rear strut. A pair of left and right front and rear lower rail members that are fixed to the lower ends of the support columns and whose rear ends are fixed to the outside of the supporting rear support columns, and a pair of left and right front and rear lower rail members that are spaced apart from each other at a fixed interval. And a pair of left and right upper rail members positioned in parallel with each other in the front-rear direction, the pair of left and right upper and lower rail members being the same rack, and the rear side of the front support column for supporting the lower rack. When nesting so that it is positioned from the front support column of the upper rack, the pair of left and right front and rear upper rail members of the lower rack and the pair of left and right front and rear lower rail members of the upper rack can slide forward and backward. The cross-sectional shape fits to each other It is intended to propose a role for the rack.
