Abstract
A wheel support device having a base member, a pair of supporting arms attached to the base at each end thereof and attachable to a wheel hub in a common plane which extends through a longitudinal axis defined by the pivotal points of a pair of rotatable casters attached to the base member in spaced relationship to each other. Each caster assembly includes a protective skirt disposed to prevent the engagement between foreign objects and the casters.
Claims7
A wheel support device for attachment to a vehicle wheel hub by lug bolts associated therewith, said device comprising:
- a generally rectangular base member having an upper and a lower surface, each of said surfaces having a proximal, and distal end, a first edge and a second edge;
- a first pivotal center mounted to said lower surface of said base member adjacent said distal end;
- a second pivotal caster mounted to said lower surface of said base member adjacent said proximal end, the axis of rotation of each said casters intersecting the plane of said upper surface at a point, said points defining a longitudinal axis therebetween which is generally parallel to said first edge and said second edge and intermediate thereof;
- a first bracket mounted on said base member adjacent said distal end intermediate said first and said second casters;
- a second bracket mounted on said upper surface of said base member adjacent said proximal end intermediate said first and said second casters in spaced relationship to said first bracket;
- a first arm member rigidly attached to said first bracket and having an inner and an outer face surface defined thereon in spaced generally parallel relationship to each other, said inner surface being disposed in coplanar relationship to said longitudinal axis, said first arm member having an aperture defined therethrough between said surfaces for receiving a first wheel lug bolt in detachable secured relationship therewithin;
- a second arm member pivotally attached to said second bracket and having an inner and an outer face surface defined thereon in spaced generally parallel relationship to each other, said inner surface being disposed in coplanar relationship to said longitudinal axis, said second arm member having an aperture defined therethrough between said surfaces for receiving a second wheel lug bolt in detachable secured relationship therewithin, each said inner face surface of each said arm member being adapted to engage said wheel hub in surface-to surface engagement therewith when said lub bolts extend into and through said apertures, said surface-to-surface engagement lying in coplanar relationship with said longitudinal axis.
