Display stand with rollers arranged to elevate and to resist accidental movement but to facilitate manual pushing, pulling, or turning movement

摘要

A display stand has a front wall, a back wall, and two side walls defining four lower corners of the display stand. Near each lower corner, the display stand is equipped with a base, which is equipped with a first roller mounted to the base so as to be freely rotatable about a generally horizontal axis and with a second roller mounted to the base so as to be freely rotatable about a generally horizontal axis. The axes about which the first rollers are rotatable are perpendicular to the axes about which the second rollers are rotatable. Each of the first rollers is located beneath a respective one of the side walls, near a respective one of the front and back walls. Each of the second rollers is located beneath a respective one of the front and back walls, near a respective one of the side walls. Being so arranged, the rollers elevate the display stand above a floor and resist accidental movement of the display stand, as on a sloping floor, but facilitate manual pushing, pulling, or turning movement of the display stand.
