Abstract
Abstract A cart for transporting articles of merchandise or human bodies comprises a bed supported principally on four legs having an Xframe configuration. The legs are capable of being angulated with respect to each other to change the level of the bed. One pair of legs is formed in two sections, the lowermost section being pivotable with respect to the upper section to permit it to swing into substantial alignment with the fixed legs. This enables a single operator to thrust the cart into a vehicle while standing at one end of the cart. In addition, the legs may be adjusted to vary the level of a cart by a single operator.

Claim 6
Dependent Claim
63 words
A cart as in claim 1 further comprising: means slidably mounting the upper ends of one pair of said legs on said bed, releasable means normally bracing said upper ends of said one pair of legs to hold said cart in an erect condition, said releasable means when released permitting said X-frame to collapse until said legs lie generally flat along said bed.
Claim 7
Dependent Claim
51 words
A cart as in claim 5 wherein said slidable mounting means includes: a transverse crosspiece secured to the upper ends of said one pair of legs, a longitudinally extending latch bar secured to said bed, and a sliding member pivotally secured to said crosspiece, and slidingly mounted on said latch bar.
Claim 8
Dependent Claim
67 words
A cart as in claim 6 wherein said releasable means includes: a plurality of notches in said latch bar, pivotable pin means carried by said sliding member and having a portion normally biased toward and residing in at least one of said notches, and means for urging said pin means out of said notches to permit adjustment of said X-frame and of the level of said bed.
Claim 9
Dependent Claim
58 words
A cart as in claim 7 wherein said means for urging said pin means out of said notches comprises: a releasing bar, release bar actuating means, and first and second means at the end of said releasing bar for cooperating to raise said releasing bar and said pivotable pin means when said release bar actuating means are operated.
