ABSTRACT:
A foldable utility cart is disclosed having first and second pairs of support legs (4, 6) at opposite sides thereof. The support legs (4, 6) are pivotal coupled at mid-sections (14, 16) so as to selectively diverge and converge into free standing and storage positions. The mid-sections (14, 16) have incut channels (24, 38) transversely disposed to each other and which interfit to being the pivotally connected legs (4, 6) into a common plane. Internal side walls (26, 28, or 40, 42) defining the incut channel of one leg mid-section brace against the top and bottom surfaces of the opposite leg mid-section. The side walls (26, 28 or 40, 42) are angularly profiled to limit and lock the pivotal rotation of the opposite leg at the free standing and storage angular positions. A shelf (12) is further provided which breaks upward at its mid-section into half sections (56, 58) which overlap along the break to lock the shelf (12) in a horizontal configuration. Overlapping structure (84, 86) is provided to limit downward deflection of the shelf sections (56, 58) beyond the horizontal plane and to brace the cart against accidental collapse.
