FOLDING SHELF
4 Claims. (Cl. 211—93)
This invention relates to shelving and more particularly
to foldable utility shelves.
The utility shelf according to the invention ?nds a
ready application in homes, stores and o?ices for many
varied uses.
It may be used, by way of examples, as a
display shelf, a spice shelf, a ?ower pot shelf, a knick~
knack shelf, a bathroom shelf to support an electric razor
and toilette articles, a display shelf for small articles on
a store counter and for numerous other purposes.
In the manufacture and distribution of utility shelves,

lar relationship to the angle supports 6, 6a the backs of
which also serve to limit the pivoting of the shelf 16a
beyond this position. Shelf 16 is maintained in a posi
tion similar to that of shelf 16a in the same manner by
means of detents 36, made by cutting slits in the angle
and bending the metal slightly inwardly.
For storing or packaging the shelf in a minimum of
space, the shelf is folded by swinging shelf 16a about
pivot rivets 14, 14a back of the supports until this shelf
reaches the position shown in dotted lines. The bottom
shelf 16 is likewise swung 90° until it is nested in an
upright position between the angle supports 6, 6a.
It will be apparent that in this folded position the
