Steering assembly for surface cleaning device

摘要

A surface cleaning device having a steering assembly is provided. The surface cleaning device includes a foot, a handle assembly with a user manipulated handle, and a steering assembly coupling the handle assembly to the foot. The steering assembly includes a means for biasing the foot with respect to the handle assembly. Movement of the handle assembly stores energy within the biasing means so that the biasing means exerts a corresponding force on the foot.

主权项

1. A surface cleaning device operable to clean a surface, the surface cleaning device comprising:
a foot; a handle assembly including a user manipulated handle, the handle assembly being pivotally coupled to the foot for movement between an upright position and an inclined position; a steering assembly including a biasing member coupled between the handle assembly and the foot; and a suction conduit extending between the foot and the handle assembly to provide fluid communication from the foot to the handle assembly, the suction conduit being positioned outside of the steering assembly; wherein the handle assembly includes a longitudinal axis and an axis of rotation formed at an acute angle relative to the longitudinal axis, and wherein rotation of the handle assembly relative to the foot about the axis of rotation stores energy within the biasing member such that the biasing member exerts a corresponding force on the foot to encourage turning of the foot; and wherein the biasing member moves with the handle assembly relative to the foot when the handle assembly pivots between the upright position and the inclined position.
