CA 2238450

A vertically adjustable wheel assembly for movably supporting an appliance cabinet or the like upon a supporting surface includes a housing, a supporting bracket, a wheel unit, an adjusting rod, an adjusting screw and various elongated mounting members. The wheel unit is defined by a pair of spaced rollers that are interconnected by a reduced diametric portion. The wheel unit is rotatably attached to the support bracket by an axle member, while the adjusting rod is also mounted for rotary movement by the support bracket. The support bracket is pivotally mounted to the housing, with both the wheel unit and the adjusting rod being permitted to rotate relative thereto. The adjusting screw extends through a frontal portion of the housing and it is threadably connected to the adjusting rod such that rotation of the screw causes pivoting of the support bracket relative to the housing and movement of the wheel assembly between fully extended and fully retracted positions. With the rollers of the wheel unit being laterally spaced, the adjusting screw is permitted to extend between the rollers when the adjustable wheel assembly assumes the retracted position. The arrangement represents an extremely compact vertically adjustable wheel assembly that can be advantageously preassembled and attached to a refrigerator cabinet or the like as a unit.
