Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
137 words
A method of uniformly lifting and lowering a transportable object supported upon uneven terrain, the steps of: a. providing supporting legs at predetermined spaced locations on the transportable object, each supporting leg having a second member initially independently longitudinally displaceable relative to a corresponding first member; b. displacing the second member of each leg a non-uniform distance accommodating leveling of the transportable object with respect to the terrain; c. connecting the second members of the supporting legs directly together with an unbroken flexible line so that changes in the effective length of the one leg will cause a corresponding change in the effective length of the other; and d. applying a displacing force to one supporting leg so that the second member is displaced relative to the first to change the effective length of the supporting legs.
Claim 2
Independent Claim
137 words
A method of uniformly lifting and lowering a transportable object supported upon uneven terrain, the steps of: a. providing supporting legs at predetermined spaced locations on the transportable object, each supporting leg having a second member initially independently longitudinally displaceable relative to a corresponding first member; b. displacing the second member of each leg a non-uniform distance accommodating leveling of the transportable object with respect to the terrain; c. connecting the second members of the supporting legs directly together with an unbroken flexible line so that changes in the effective length of the one leg will cause a corresponding change in the effective length of the other; and d. applying a displacing force to one supporting leg so that the second member is displaced relative to the first to change the effective length of the supporting legs.
Claim 3
Dependent Claim
62 words
A method as defined in claim 1 further comprising selectively disconnecting the flexible line from one of the legs and reconnecting the flexible line to the one leg to facilitate independent displacement of the telescoping member of the one leg whereby the transportable object, when positioned at a desired orientation, is easily reoriented by selectively adjusting the location of the line attachment.
Claim 4
Independent Claim
91 words
A method of uniformly lifting and lowering a transportable object supported upon uneven terrain, the steps of: providing supporting legs at predetermined spaced locations on the transportable object, each supporting leg having a second member longitudinally movable relative to a first member; connecting the supporting legs together with a flexible line so that displacement of the line will urge each second member toward an extended ground-engaging position, one second member extending a greater distance than the other; and selectively exerting a displacing force on the flexible line to lift the object.
Claim 5
Independent Claim
91 words
A method of uniformly lifting and lowering a transportable object supported upon uneven terrain, the steps of: providing supporting legs at predetermined spaced locations on the transportable object, each supporting leg having a second member longitudinally movable relative to a first member; connecting the supporting legs together with a flexible line so that displacement of the line will urge each second member toward an extended ground-engaging position, one second member extending a greater distance than the other; and selectively exerting a displacing force on the flexible line to lift the object.
Claim 6
Dependent Claim
62 words
A method as defined in claim 3 further comprising simultaneously extending each supporting leg from an initial position into ground engagement so that at least two of the supporting legs engage the ground before an object-lifting force is exerted by the legs; and developing an object-lifting force which is essentially uniform in each of the supporting legs by displacing the flexible line.
