<p>LUGGAGE ROLLER A luggage roller featuring a diabolo-shaped wheel, which is preferably detachable from the piece of luggage, i.e. a container, to which it is mounted. The diabolo-shaped wheel is more stable than prior art configurations, because of its greater effective width leading to greater bearing area. The detachable feature of the wheel leads to changeability of the luggage roller wheel when wear occurs, so that the piece of luggage does not have to be discarded when the installed wheel wears down. This detachable feature is typically attained by providing an axle on which the wheel is mounted which is detachable from the container. The axle is generally of one of several alternative configurations in which a threaded connection is provided between portions of the axle assemblage, so that one portion or part of the axle assemblage may be unscrewed from the other portion or part.</p> |
