Abstract

A wheeled hand-propelled scrubbing device for the upper edge portions of swimming pool side walls near the water level is disclosed. A sponge scrubbing pad is held in a vertical position by a bracket which depends from a wheeled handle. The scrubbing pad can be secured to a detachable plate to facilitate its replacement. A simple mechanism to reciprocate the scrubbing pad vertically during movement of the device can be included and a cleaning liquid dispenser can be provided on the handle of the device for delivering cleaning liquid to the pad.

Claims

1. A cleaning device for swimming pool side walls and the like comprising a wheeled handle bar adapted to be propelled and guided by a walking attendant, and a flat scrubbing pad dependingly held on the lower end of the wheeled handle bar and being substantially vertical and extending substantially below a support surface with which the wheel of the wheeled handle bar is rollingly engaged, said handle bar having an upper hand grip and a lower end extension to which the scrubbing pad is dependingly secured, the wheeled handle bar having a single wheel disposed near its lower end and near the side of the handle bar away from the depending scrubbing pad, said wheel being canted at a small divergent angle to the lower end portion of the handle bar so that the wheel tends to drive the scrubbing pad toward the side wall surface cleaned by the device when the device is in use, the scrubbing pad extending below said wheel, the scrubbing pad being disposed in a plane substantially at right angle to the axis of rotation of said wheel and said wheel and scrubbing pad being disposed laterally on opposite sides of the handle bar,

a bracket plate carrying the pad and being secured to the lower end extension, the bracket plate being substantially L-shaped and having an upper mounting flange and being secured to the lower end extension,

means on the handle bar and bracket plate and driven by the wheel of the handle bar and being connected with a backing plate of the scrubbing pad to reciprocate the same relative to the bracket plate during movement of the device while cleaning a wall surface,

and said means comprising gearing including a first gear driven directly by said wheel, a second gear on the bracket plate meshing with and driven by the first gear, the bracket plate having substantially vertical guide slot means for the scrubbing pad, and a pitman interconnecting the second gear and the guide slot means,

whereby the scrubbing pad is reciprocated substantially vertically relative to the bracket plate during substantially horizontal movement of the cleaning device.
