Abstract
A two wheel roller caster (10) for use in supporting movable objects on a floor having a conductive band (56) which has two ends and is mounted between two wheels (16) so as to provide conductive contact between the movable object and the floor. A conductive path (60, 58, 56) connects a stem (14) to the connective band (56).
Claims9
A two-wheel roller caster for use in supporting movable objects such as chairs on a floor wherein said caster includes two wheels, an axle connecting said wheels, and a housing means, the improvement which comprises:
- a conductive band having two ends mounted to said housing between said two wheels for only providing continuous conductive sliding contact between said caster and said floor, one end of said conductive band being stationary with respect to said housing;
- and
- a conductive path means connecting said conductive band to said movable object so as to permit said movable object to be electrically grounded to said floor through said conductive band.
A two-wheel roller caster for use in supporting movable objects such as chairs on a floor wherein said caster includes two wheels, an axle connecting said wheels, and a housing means, the improvement which comprises:
- a conductive band having two ends mounted to said housing between said two wheels for providing continuous conductive sliding contact between said caster and said floor, said conductive band is of a crowned, cross-sectional shape so that longitudinal edges of said conductive band permit free movement of said caster in a plurality of directions;
- and
- a conductive path means connecting said conductive band to said movable object so as to permit said movable object to be electrically grounded to said floor through said conductive band.
