Abstract: A basket assembly for use with a three-wheel pushcart having a leg brace. The assembly includes a clamp for attachment to the brace. The clamp has a block with a notch for receiving the top of the brace. The block also has a first bore extending from its top to its bottom and opening into the notch and a second bore extending from one side of the block to the other. A clamping plate, for engagement with the bottom of the leg brace, is secured to the block by means of a first threaded fastener passing through the first bore. A supporting bracket is attached to the clamp and has a pair of laterally spaced members. Each of the members has a lower segment, with a forwardly facing hook at its bottom, joined to an upper segment with an apertured flange. A second threaded fastener extends through each apertured flange and the second bore to attach the bracket to the clamp. A cross brace extends between the laterally spaced members and carries a locking member having a slot.
