Abstract

A rotatable display device, shown in the figure in plan view, has four wheels 1, each mounted on orthogonal radii, equidistant from the center of rotation 2 of a display device. Only the base 3 of the display device is shown in the figure. Each wheel 1 is attached to the base 3 by moulded lugs (not shown) and mounted perpendicularly to a radius passing through the center of rotation 2 to allow rotation of the device about the center 2. The wheels 1 should have sufficient coefficient of friction to prevent movement other than rotation about the center 2 and may be made of rubber or other suitable material. This prevents the display device from being pushed sideways.

Rotatable Display Device

A rotatable display device, shown in the figure in plan view, has four wheels 1, each mounted on orthogonal radii, equidistant from the center of rotation 2 of a display device. Only the base 3 of the display device is shown in the figure. Each wheel 1 is attached to the base 3 by moulded lugs (not shown) and mounted perpendicularly to a radius passing through the center of rotation 2 to allow rotation of the device about the center 2. The wheels 1 should have sufficient coefficient of friction to prevent movement other than rotation about the center 2 and may be made of rubber or other suitable material. This prevents the display device from being pushed sideways. Preferably, the wheels should be shaped so that their outer diameter is greater than their inner diameter to improve their rotational movement on the supporting surface.
