Abstract

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.

Claims8

Dependent claims

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.
