Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
122 words
A carriage for transporting articles of large weights comprising a base frame, a plurality of supporting legs secured to the lower surface of said base frame, a plurality of vertical fluid pressure cylinders connected to the lower surface of said base frame, a plurality of shoes, means connecting each shoe to the lower end of the piston rod of one of said vertical fluid pressure cylinders said connecting means including a pair of cooperating slide members, one of said slide members being disposed to be slidable in the longitudinal direction and the other in the transverse direction of said shoes, and a plurality of fluid pressure piston-cylinder assemblies for moving said shoes in the transversal and longitudinal directions of said base frame.
Claim 2
Dependent Claim
122 words
A carriage for transporting articles of large weights comprising a base frame, a plurality of supporting legs secured to the lower surface of said base frame, a plurality of vertical fluid pressure cylinders connected to the lower surface of said base frame, a plurality of shoes, means connecting each shoe to the lower end of the piston rod of one of said vertical fluid pressure cylinders said connecting means including a pair of cooperating slide members, one of said slide members being disposed to be slidable in the longitudinal direction and the other in the transverse direction of said shoes, and a plurality of fluid pressure piston-cylinder assemblies for moving said shoes in the transversal and longitudinal directions of said base frame.
Claim 3
Dependent Claim
35 words
The carriage according to claim 1 wherein said base frame takes the form of an inverted rectangular box and said supporting legs are provided at four corners and at the center of said base frame.
Claim 4
Dependent Claim
82 words
The carriage according to claim 1 wherein each shoe comprises an integral slide bed extending in the longitudinal direction of said shoe, one of said slide members is slidably mounted on said slide bed and is provided with a groove extending in the transverse direction of said shoe for slidably receiving the other slide member, and the lower end of the piston rod of one of said vertical fluid pressure cylinders is connected to said other slide member through a universal joint.
Claim 5
Dependent Claim
67 words
The carriage according to claim 1 wherein pairs of said fluid pressure piston-cylinder assemblies are provided between adjacent shoes in the longitudinal and transverse directions of said base frame, one end of the piston rod of each piston-cylinder assembly is pivotally connected to the shoe whereas the opposing ends of the cylinders of each pair of fluid pressure piston-cylinder assembly are pivotally connected to said base frame.
Claim 6
Dependent Claim
29 words
