Claim 1
Independent Claim 265 words
Cart comprising: (a) a first frame portion, (b) a storage compartment which is supported on the first frame portion, (c) a pair of wheels which are mounted on the first frame portion on opposite sides of the storage compartment for rotation about a horizontal axis, said wheels forming two support points for said cart, (d) a second frame portion which is operatively connected to said first frame portion so that said second frame portion lies substantially in a plane which is at a right angle to said axis, said second frame portion having a support foot which forms a third support point for said cart for supporting said cart when it is stationary, said second frame portion is pivotally connected to said first frame portion for movement between and operative position in which said second frame portion is located with said plane to an inoperable position in which said second frame portion lies in a plane which is parallel with said axis and adjacent said storage compartment so that said cart defines a more compact configuration for storage, said pivotal connection including releasable locking means for locking said second frame portion in said operative position, (e) a handle which is mounted on the second frame portion and which is vertically spaced from said foot for lifting said foot from the ground to enable the cart to be pushed or pulled on said wheels, and (f) a seat mounted on the second frame portion so that it is located vertically between said handle and said support foot and horizontally between said handle and said storage compartment.
