The mobile stand is generally L-shaped in side elevation, having a horizontally extending base and an upright mast adjacent the rear of the base. The base is somewhat H-shaped in top plan, having a pair of widespread, parallel, horizontal legs that extend slightly rearwardly beyond the mast, and a crossbar that rigidly interconnects the legs adjacent their rear ends. The mast is fixed to the crossbar midway between the two legs. Four rubber stabilizer feet project downwardly from the base at its four corners to space the base a short distance above the floor. Transport wheels at the rear ends of the legs project downwardly from the base but do not engage the floor when all four of the feet are touching the floor, thus rendering the wheels ineffective at such time. When the stand is tilted back about the rear set of feet, the wheels are brought down into supporting engagement with the floor, such that further tilting back of the stand results in completely raising the feet off the floor and placing the entire load on the transport wheels so as to adapt the stand for transport to a new location.

1. A mobile stand for supporting an object in an elevated position above a floor, said stand comprising: a rigid frame including a normally horizontally extending base including a plurality of legs, and a normally upwardly extending mast adjacent a rear of the frame, said mast being operable to releasably support an object in overhanging relationship to the base; a plurality of floor-engaging stabilizer feet projecting downwardly from the base for spacing the base a distance above the floor; and a pair of laterally spaced transport wheels on the base at the rear of the frame, said transport wheels projecting downwardly below said base but being recessed above said feet such that the wheels do not contact the floor when all of the feet are engaging the floor, said group of feet including a pair of rear feet offset forwardly from the wheels for serving as a fulcrum about which the frame may be selectively tilted back to bring the wheels down into contact with the floor, said offset between the rear feet and the wheels permitting the wheels to become the fulcrum for the frame after the wheels have contacted the floor whereby further tilting back of the frame results in raising all feet off the floor and supporting of the frame by the wheels. 2. A mobile stand as claimed in claim 1, wherein said legs project rearwardly beyond said mast, and said wheels are disposed at rear ends of said legs. 3. A mobile stand as claimed in claim 2, wherein said legs are configured to define an internal chamber, and said wheels are partially housed within said chamber. 4. A mobile stand as claimed in claim 3, wherein said chamber has an internal height dimension substantially corresponding to a diameter of said wheels, said rear ends of the legs each have an angled rearmost edge projecting upwardly and rearwardly at an angle of less than 45°, and each of said wheels has an axis of rotation disposed inward from a rearmost edge of a corresponding one of the legs, and a floor-engaging periphery that projects beyond and below the rearmost edge. 5. A mobile stand as claimed in claim 4, wherein said mast has a strut spring compressor mounted thereon by which the mast supports an object, said object comprising an automotive strut, and said stand and strut spring compressor have a collective center of gravity disposed substantially directly above an axis of rotation of the wheels when the frame is tilted back approximately 25° from vertical. 6. A mobile stand as claimed in claim 1, wherein said mast has a strut spring compressor mounted thereon by which the mast supports an object, and said object comprises an automotive strut. 7. A mobile stand as claimed in claim 1, wherein said base further includes a crossbar rigidly interconnecting said legs, and said mast is fixed to said crossbar. 8. A mobile stand as claimed in claim 1, wherein said mast has a handle adjacent its upper end.
