Abstract: An object may be easily moved across a surface by means of a rotatable roller mechanism, and may be secured in a desired location on that surface by rotation of the roller mechanism. The rotatable roller mechanism comprises a rigid plate containing a slot, a bar designed to seat within that slot, a holding mechanism allowing the bar to rotate in close proximity to the slot in the rigid plate, and a roller mechanism attached to the bar. The roller mechanism may consist of wheels or flat rollers surrounding an axle, which is attached to the bar by two connecting pieces. The rigid plate is attached to the underside of the object. When the object is lifted, the bar rotates in the holding mechanism to a position perpendicular to the rigid plate. The bar is held in this position when the object is lowered, by means of the bar fitting into the slot. In this manner the rollers are held against the surface, and the object may be easily moved across the surface.
