Abstract
A support assembly for a surface treating appliance includes a central roller arranged to engage a surface and outer rollers at either end of the central roller. The rollers together define a rolling support surface, and the outer rollers rotate about an axis spaced from the rotational axis of the central roller. This arrangement of rollers provides a rolling support surface over a wide range of motions, and spacing the rotational axes of the rollers permits the rollers to be arranged relative to one another to define a region into which components of the appliance are mountable.
Claims19
A support assembly for a surface treating appliance or a surface treating head, comprising a plurality of rollers in combination defining a rolling support surface, the rollers comprising a central roller arranged to engage a planar floor surface and a pair of outer rollers at opposite ends of the central roller, each outer roller sharing a common rotational axis spaced from a rotational axis of the central roller and the rotational axis of the central roller passing through each outer roller and being fixed relative to the common rotational axis of the outer rollers.
A surface treating appliance comprising a support assembly, a main body having a longitudinal axis and a surface-treating head, the support assembly comprising a plurality of rollers in combination defining a rolling support surface, the rollers comprising a central roller arranged to engage a planar floor surface and a pair of outer rollers at opposite ends of the central roller, each outer roller sharing a common rotational axis spaced from a rotational axis of the central roller, the rotational axis of the central roller passing through each outer roller and being fixed relative to the common rotational axis of the outer rollers and wherein the support assembly is arranged to roll with respect to the main body for allowing the appliance to be rolled along a surface.
