Roller for luggage and other objects
Abstract
Abstract An elongated plate, attachable under luggage and other objects, preferably of magnetically attractable material, contains a relatively thin, flat member underneath with a small space between one lateral side and the elongated plate and toward the other side a screw-threaded hole. In its lateral rim on the side with the small space, the flat member, optionally, is indented and has toward this side a cavity extending up to the elongated plate. The plate with the flat member is sufficiently thin and flat so as not to upset the upright position of the luggage or other object under which it is fastened. A separate and releasably attachable roller member with a roller under a platform contains a relatively thin fastening element extending angularly upward from one side of the platform to the level of the top of the flat member when attached, and extending angularly over and compactly into the small space below the elongated plate. Toward the other side the roller platform has a headed machine screw that registers up into the screw-threaded hole in the flat member. Optionally the fastening element is provided with a projection that protrudes into the dent in the rim of the flat member, and the roller platform a magnet projecting from its top surface, insertable into the cavity in the flat member, detachably clinging to the elongated plate.
