ABSTRACT:
An improved castor for use with pile carpet can be built so as to include a plurality of separate wheels located on a sleeve which in turn is rotatably mounted on an axle. Holders are provided to secure the wheels in place on the sleeve in side-by-side relationship so that normally the wheels will rotate together as a unit and so that the wheels are capable of rotating independently of one another. The wheels are provided with non-pointed bosses extending from their peripheries which are intended to engage a pile carpet so as to avoid crushing of the piles of the carpet. The structure is intended to distribute weight on the castor over a reasonably large area of the carpet and is intended to facilitate the castor being turned or rotated during use without the movement of the castor detrimentally affecting the carpet.
