Abstract

A bifurcated hose junction is provided for a pole mounted abrading device with vacuum assisted particulate removal. The junction is actuated by the movement of the sanding pad assembly. When a. short side of the rectangular sanding pad assembly is moved toward the tubular handle, the bifurcated hose junction is displaced laterally in relation to the linear axis of the handle. When a long side of the sanding pad assembly is moved toward the tubular handle, the bifurcated hose junction rotates in place, thereby allowing the sanding pad a comprehensive range of motion, in relation to the handle. The range of motion enables the operator to close the angle between sanding pad and the handle, and maintain planar contact between the sanding screen and the work surface, when working in constricted areas. The sanding pole of the application also provides an unobstructed passageway to maintain the laminar flow of the air stream, thereby reducing turbulence and conserving the energy available to transport the particulate to the vacuum source. Conserving energy maintains the efficiency of the system, allowing the operator to maintain a high sanding pace without reducing the effective removal of abraded particulate.

Claims4

Dependent claims

A vacuum pole sander for sanding a work surface and vacuuming abraded particles sanded therefrom, comprising:

an elastomeric sanding pad, said sanding pad having a base carrying a plurality of upstanding support pegs, said support pegs being arranged in rows to maximize laminar flow of air along the open channels formed between said rows, each of said support pegs having a first end connected to said base and a freestanding tip, wherein said base and said plurality of upstanding support pegs are integrally formed together,
a flexible and porous sanding screen carried by said freestanding tips of said support pegs, whereby abraded particles pass directly through said porous sanding screen and into the channels formed between said rows of pegs,
a rigid and hollow tubular handle for supporting said sanding pad and allowing application of vacuum therethrough,
means for removably connecting said sanding pad to said tubular handle whereby said sanding pad is supported by and articulates relative to said tubular handle, and
hose junction means for establishing a fluid communication between said hollow, tubular handle and said sanding pad, said hose junction means being removably connected to said hollow, tubular handle, whereby said sanding pad and hose junction means can be readily disconnected from said hollow, tubular handle.
