Abstract

Abstract An adjustable tool is provided which includes a selectively positionable and lockable handle. The tool includes a main housing having a handle shaft axially directed transversely of the housing and a handle being rotatably mounted to the handle shaft for selective rotational movement about the handle shaft. The handle shaft has a threaded portion and threadedly advanceable thumbwheel at one end and a handle retaining pad at an opposite end. The handle is interposed between the thumbwheel and the retaining pad for compressive retention between them. The retaining pad includes a locking member comprising a protrusion for nesting reception in a locking member receiving port of the handle whereby upon advancement of the thumbwheel the handle is compressively retained between the thumbwheel and the retaining pad and the locking member protrusion is received in the receiving ports for locking the handle in a selected position relative to the main housing.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 324 words
An adjustable scraping and sanding tool including a housing, an adjustable handle operatively connected thereto and a pad releasably attached to the housing, the housing having a bottom wall about the periphery of the housing, the wall sized for releasably receiving a painting or a sanding pad, the housing having a generally prismatoidal configuration and a substantially centrally positioned undercut, the housing including a handle shaft substantially within the centrally positioned undercut but being exposed for reception of the handle, the handle shaft including a retaining pad having a diameter greater than the diameter of the shaft, the handle shaft further including a thumbwheel with an internally threaded opening, the handle shaft having a threaded portion along its length, spaced from the retaining pad to threadedly engage the thumbwheel, whereby the thumbwheel is rotatable on the shaft toward and away from the retaining pad in order to compressively retain the handle, the thumbwheel being substantially within the undercut but exposed therefrom, the handle including a shaft through-hole for rotatable reception of the shaft between the retaining pad and the thumbwheel, at least one locking protrusion on one of the retaining pad and the handle and a plurality of grooves in the other for mating reception of the retaining pad and the handle, the handle further having a receiving slot for close reception of a scraper, a scraper closely received in the receiving slot, the pad including a clip-on support member so that the pad may be releasably attached to the bottom walls of the housing whereby the angle of the handle of the tool may be manually adjusted relative to the housing with one hand by rotating the thumbwheel away from the retaining pad until the protrusion no longer engages a groove, angularly moving the handle relative to the housing and then rotating the thumbwheel so that it moves toward the retaining pad thus causing the protrusion to move into one of the grooves.
Claim 2
Dependent Claim 324 words
An adjustable scraping and sanding tool including a housing, an adjustable handle operatively connected thereto and a pad releasably attached to the housing, the housing having a bottom wall about the periphery of the housing, the wall sized for releasably receiving a painting or a sanding pad, the housing having a generally prismatoidal configuration and a substantially centrally positioned undercut, the housing including a handle shaft substantially within the centrally positioned undercut but being exposed for reception of the handle, the handle shaft including a retaining pad having a diameter greater than the diameter of the shaft, the handle shaft further including a thumbwheel with an internally threaded opening, the handle shaft having a threaded portion along its length, spaced from the retaining pad to threadedly engage the thumbwheel, whereby the thumbwheel is rotatable on the shaft toward and away from the retaining pad in order to compressively retain the handle, the thumbwheel being substantially within the undercut but exposed therefrom, the handle including a shaft through-hole for rotatable reception of the shaft between the retaining pad and the thumbwheel, at least one locking protrusion on one of the retaining pad and the handle and a plurality of grooves in the other for mating reception of the retaining pad and the handle, the handle further having a receiving slot for close reception of a scraper, a scraper closely received in the receiving slot, the pad including a clip-on support member so that the pad may be releasably attached to the bottom walls of the housing whereby the angle of the handle of the tool may be manually adjusted relative to the housing with one hand by rotating the thumbwheel away from the retaining pad until the protrusion no longer engages a groove, angularly moving the handle relative to the housing and then rotating the thumbwheel so that it moves toward the retaining pad thus causing the protrusion to move into one of the grooves.
Claim 3
Dependent Claim 34 words
The tool as claimed in claim 1 wherein the handle has an axially extending threaded bore in the end of the handle opposite the end connected to the housing for receiving an extending item.
Claim 4
Dependent Claim 20 words
The tool as claimed in claim 2 wherein the handle has raised portions along its length to aid in gripping.
Claim 5
Dependent Claim 14 words
The tool as claimed in claim 1 wherein the pad is a sanding pad.
Claim 6
Dependent Claim 14 words
The tool as claimed in claim 1 wherein the pad is a painting pad.
