The bottom member 22 preferably is sheet metal formed
knockdown form and easily assembled at the point of dis
play or use, which is of metal in its major components,
yet is of relatively light weight, which minimizes dropping
of sand, yet is supported on spaced feet ‘or legs, and which
avoids sharp metal corners, edges and the like.
Therefore, an object of the present invention is to pro

URE 12, the depending ?anges 32 and 34 are cut away
at the corners to facilitate ?tting together of the parts, as
is set forth below. Reinforcing strips 36 of Wood or
other suitable material are secured beneath the ‘bottom

Another object is to provide a novel sandbox for chil

when assembled, provides a receptacle for sand, reducing

Each side rrnernber 24 includes a rolled upper edge por

forms 1a channel with the lower part of the main body of
