ABSTRACT:
A caster for providing rolling support including a spring-loaded mount. The caster may be substantially concealed in the bottom edge of a hinged, swinging door, and generally located proximate to the free vertical edge of the door. An elongated spring plate is provided as a mount for a roller, causing the roller to accommodate variations in the floor surface, maintain contact with the floor, and support the door. The spring plate has a first portion adapted to be mounted to the bottom edge of a door, and a second portion depending from the first portion. An axle is mounted to the second portion, inside a hub that is mounted to the roller. The axle may be substantially parallel to the first portion of the spring plate. Single roller and double roller caster assemblies are provided.
