Patent number: 6283698Abstract: A moving system (1) made up of a number of separable but intergratable parts and platform sections (10-90/110-190), including an elastically biased, pivoted, integral end ramp section (10) which is moved down allowing the load (e.g. a copier with “convenience casters”) to be rolled up onto platform sections (40 & 50/140 & 150) for movement from one location to another. Also included are additional parts or sections—in one embodiment or the other a supplemental ramp piece (120), usually stored on the exterior side of the ramp end section (110) when not in use but connectable to the end of the main ramp section to extend the effective ramping distance; a protective pad (30/130) for the ramp end section; a first platform section (40/140); a second platform section (50/150), an auxiliary, pivoting, intermediate braking support member (160); a handle end section (70/170); an extendible handle (80/180); and an interconnecting, ninety (90°) degree, leg section (90/190).Type: GrantFiled: June 27, 2000Date of Patent: September 4, 2001Assignee: Lee Inventions, Inc.Inventor: William S.

Patent number: 4037739Abstract: A heavy duty moving system including a base sled having two sets of integral, drop-leaf, heavy duty caster wheels (FIG. 1) and a lever arm assembly (FIG. 6) for moving heavy equipment, for example, the "XEROX" copy machines of the 2400 series. The sled is slid under the machine (FIG. 8) and then raised at one end by the lever arm assembly (FIG. 9), after which one set of integral, drop-leaf caster wheels are lowered into position and locked. The opposite end of the sled is jacked up and the second set of integral, drop-leaf caster wheels are lowered and locked into position after which the lever arm assembly is removed. The machine then rests on the sled and its caster wheels and is ready for transportation. The machine is taken off the moving system in the opposite manner.Type: GrantFiled: September 18, 1975Date of Patent: July 26, 1977Assignee: Lee Inventions, Inc.Inventor: William S. Lee

Patent number: 3997070Abstract: A stair climber moving system (FIGS. 1-2) for moving a load up flights of stairs FIGS. 4A-4H) which includes a basic tractor unit, a load mounting platform attached to the tractor which allows the load to be shifted longitudinally with respect to the tractor during use, and a collapsible dolly (FIGS. 3A-3D) permitting load changes from horizontal (3B) and inclined (3D) positions.The collapsible dolly includes a fixed horizontal bottom platform supported by five sets of caster wheels. A collapsible load bearing platform is mounted and supported on the fixed bottom platform by a fixed center vertical strut member through a hinge connection. At opposed ends of the collapsible load bearing platform are auxiliary, end, support members, one fixed and the other collapsible, the latter of which is spring biased in a normally vertical, supporting disposition. The load bearing platform is collapsible, i.e.Type: GrantFiled: June 26, 1975Date of Patent: December 14, 1976Assignee: Lee Inventions, Inc.Inventor: William Smith Lee
