Claim:
In combination, a wheel-immobilizing device, comprising: a generally flat base member; a pair of spaced apart side members extending upwardly from said base member and defining a wheel-receiving opening therebetween, said side members each having a slot at an upper portion thereof spaced from said base member; a first cross member extending between said side members and securely fixed therebetween, said first cross member being located at a position generally opposite to said wheel-receiving opening; and a movable second cross member that 1) in a first, open position thereof does not extend between said side members and that 2) in a second, closed position thereof extends through the slot in each of said side members at a position spaced from said first cross member; wherein said second cross member and said side members are cooperatively configured such that said second cross member can be secured in said second, closed position; and a cart or cabinet supported on a flat surface by at least one stem-mounted wheel, wherein said wheel-immobilizing device is disposed on the flat surface with said side members extending upwardly from said base member, said stem-mounted wheel is disposed on top of said generally flat base member between said pair of spaced apart side members, and said second cross member is secured in the second, closed position with the stem of said stem-mounted wheel extending upwardly between said first and second cross members, whereby rolling movement of said cart or cabinet is impeded by securement of said wheel-immobilizing device to said stem-mounted wheel.
