  • Patent number: 4025676
    Abstract: A skid for slidably supporting and moving heavy objects. The skid has an elongated load bearing strip of hard fiber-board material with a strip of cushioning material bonded to the top surface of the load bearing strip. A strip of flexible tape-like material having pressure sensitive adhesive on the top surface is bonded to the top surface of the cushioning material. The top adhesive surface of this material is adapted to secure the skid to the bottom portion of an object. The bottom surface of the load bearing strip is covered with a hard, smooth glossy surface when the object is adapted to rest on a floor having a soft covering. Alternatively, the bottom surface is covered with a moisture resistant, static-free, wax impregnated, matted fiber fabric when the object is adapted to rest on a floor having a hard covering or finish. The load bearing strip also may be formed with a plurality of transversely extending grooves to facilitate separation of the skid into a plurality of smaller skid-like sections.
