Abstract
Abstract A transport carriage having a frame comprising a rear wall and side walls connected to said rear wall with running wheels and means enabling several transport carriages of this type to be stored in each other in a space-saving way. The frame is pivotally mounted on a rear carrying member or supporting means. At least one of the side walls of the frame is pivotally connected to the rear wall whereas the remaining parts of said frame, i.e. the rear wall and second side wall are fixed forming a L-shaped structure, thus enabling the carriage to be brought into transport condition -- in which the side walls are positioned parallel to each other -- or into storing condition -- in which the side walls are expanded outwardly.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
148 words
Transport carriage comprising a horizontally extending supporting means having at least one running wheel, and a vertically extending frame, said frame comprising a rigid rear wall and a pair of rigid side walls, at least one side wall being pivotally connected to said rear wall, a bearing pin interconnecting said supporting means and the rear wall of said frame to permit said frame to pivot about a vertical axis with respect to said supporting means, and at least one running wheel provided at the forward portion of each of said side walls, said frame being pivotal about said bearing pin, and said pivotal side wall being movable with respect to said rear wall between a first position wherein said side walls are parallel to each other for transport condition and a second position wherein said side walls diverge outwardly into nesting condition with another similarly constituted transport carriage.
Claim 2
Dependent Claim
148 words
Transport carriage comprising a horizontally extending supporting means having at least one running wheel, and a vertically extending frame, said frame comprising a rigid rear wall and a pair of rigid side walls, at least one side wall being pivotally connected to said rear wall, a bearing pin interconnecting said supporting means and the rear wall of said frame to permit said frame to pivot about a vertical axis with respect to said supporting means, and at least one running wheel provided at the forward portion of each of said side walls, said frame being pivotal about said bearing pin, and said pivotal side wall being movable with respect to said rear wall between a first position wherein said side walls are parallel to each other for transport condition and a second position wherein said side walls diverge outwardly into nesting condition with another similarly constituted transport carriage.
