Abstract: A device for lifting office partitions sufficiently to allow floor tiles upon which the partitions normally rest to be replaced, without disassembling the partitions, employs L-shaped brackets having horizontally extending tabs which may be wedged beneath the partitions. A manually reciprocated handle pumps fluid into a cylinder to force a piston outwardly so that the piston rod rotates a lever to lift the brackets and raise the partitions.

Abstract: A device for lifting office partitions having a housing with a main body portion and spaced apart base legs. The main body portion is spaced upwardly from the base legs at one end of the housing to form an open channel between the main body portion and the base legs. An elongated lever has one end pivotally mounted about a first axis to the housing. A piston and cylinder assembly is movable between a retracted and extended position. One end of the piston and cylinder assembly is secured to the housing while the second end is pivotally secured to the lever about a second axis parallel to but spaced radially from the first axis. A lift bracket is attached to the other end of the lever so that the lift bracket vertically moves in synchronism with the extension and retraction of the piston and cylinder assembly. A torsion bar assembly is disposed between the main body portion of the housing and the base legs adjacent the lift bracket.

Abstract: A floor covering installation tool for raising and lowering furniture, partitions or the like has a frame, a raising and lowering mechanism and a lifting assembly. The frame or the lifting assembly has a portion which is positioned underneath the object to be lifted. The raising and lowering mechanism is actuated to raise or lower the object to be lifted. Upon raising the lifted object to a desired height, flooring or the like is positioned underneath the lifted object. After the flooring is positioned underneath the lifted object, the raising and lowering mechanism is activated to release the lifting mechanism and return it to its original position. Thus, the tool is ready to be reused to lift another desired object.

Abstract: A floor covering installation tool for lifting partitions, furniture or the like. The tool includes a mechanism for raising and lowering a bracket. The bracket includes a member for securing the bracket to the raising and lowering mechanism. One or more lifters adapted for raising and lowering furniture, partitions or the like are coupled with the bracket. One or more elongated elements are coupled with the raising and lowering mechanism. The elongated elements may include a wedging mechanism to enable the moving of the elongated elements underneath furniture, partitions or the like.
