or furniture rolls, however, arise difficulties when they be used on very soft floors, such as deep-pile carpets, in which the rollers are very deep penetration. In these cases sliders are used that have a relatively large and smooth load-transferring surface, so that instead of rolling, the piece of furniture glides over such a soft floor.

The invention is based on the object of providing a roller or sliding element for supporting pieces of furniture or the like. to create, which at the same time as a roller and sliding element can be effective.

To achieve this object, the roller or sliding element according to the invention is characterized in that the body on its underside is provided with downwardly directed support surfaces or lugs, which are associated with load-transferring Grip together support surfaces of the ground, and that the Caster protrudes sufficiently far through a recess in the floor to be the only one on a hard, smooth floor to form the floor coming into contact movable or rotatable load transmission surface, such that the element overall acts as a Hollelement, while the roller on a soft floor, such as a deep-pile Carpet sinks into this and acts as a load-transferring surface except for the floor, its smooth downward facing In this case, the underside forms a load-transferring sliding surface, so that the element is partially used as a roller and is partially effective as a sliding element.

The invention also relates to a roller or slide element for supporting pieces of furniture or the like on the floor, with a body that can be attached to the underside or the feet of the piece of furniture so as to be pivotable about a vertical axis, for inserting a rotatable roller in a position eccentric to its vertical pivot axis Storage or support elements is provided.

The arranged on the outside of the bottom 30,

3Q982S / 0301

circumferential recess or gradation, an upwardly directed annular surface 46 is formed on which the after downwardly directed annular surface 39 of the body 10 is supported.

The bottom 30 is in its interior on both sides of the recess 35 provided with two upwardly projecting, diametrically opposed projections 37, which have an annular Have recess 38 into which the lower ends of downwardly projecting tubular lugs 40 protrude are made in one piece with the body 10.

After the overall assembly, the base 30 is preferably firmly connected to the body 1.0 by means of an adhesive, which is preferably can be placed in the annular recesses 38, so that there is no possibility that the bottom during the use of the caster from the body 10 can be solved. The support of the part of the body forming, downwardly projecting lugs 40, which also are arranged symmetrically on both sides of the roller 25 on a diametrically extending axis, on the after above projections 37 of the bottom 3O is essential of practical importance, since the floor 30 is thereby supported on a considerable surface area within the periphery is, whereby a safety factor in terms of load capacity is created when the roller element as Furniture rolls or glides is effective.

On a soft floor surface, the roller 25 forms the only load-bearing surface resting on the floor. The roller element is effective in the usual way as a furniture roll or glider. On a sufficiently flexible floor The underside of the floor comes in like a deep-pile carpet into which the roller can penetrate additionally in contact with the floor and then acts as a sliding element, which accounts for a significant proportion of the total load takes over. The piece of furniture is then moved by sliding, while the roller effect is only slight
