Handle arrangement for air power tool

An air tool including a housing containing an air motor with a shaft rotatable about a longitudinal axis and connectable to an implement for working the surface of a workpiece, right and left handles having upper and lower ends, and upper and lower connections respectively securing said upper and lower ends of said handles to said housing, said upper and lower connections for each of said handles having longitudinal axes extending in directions generally perpendicular to each other.

An air tool including a housing containing an air motor with a shaft rotatable about a longitudinal axis and connectable to an implement for working the surface of a workpiece, right and left handles having upper and lower ends, and upper and lower connections respectively securing said upper and lower ends of said handles to said housing, said handles being angularly spaced from each other by a preselected angle less than one-hundred eighty degrees (180.degree.) relative to said longitudinal axis, each of said handles including upper and lower generally radially extending legs and a substantially upright leg extending therebetween, said lower legs each having radially inward ends secured to said housing by said lower connections, and each of said generally upright legs extending radially inward toward said housing upon progressing upwardly from said lower leg toward said upper leg and having a longitudinal axis angled at approximately 15.degree. with respect to said longitudinal axis of said shaft.

In an air tool including a housing containing an air motor with a shaft connected to an implement for working the surface of a workpiece, the improvement comprising a power handle removably connected to said housing, an idle handle removably connected to said housing and spaced less than 180.degree. arcuately from said power handle, each of said handles being connected to said housing at upper and lower positions, a vibration insulator at each of said connections, said power handle including an air power inlet and an air passage extending therethrough from said inlet to said housing adjacent the upper connection of said power handle, said vibration insulator at said upper power handle connection also serving to seal against the loss of air power between said power handle and said housing, each of said handles including upper and lower generally radially extending legs and a substantially upright leg extending between the radially outer most ends of said generally radial legs, said lower leg of each of said handles also extending downwardly from said connection with said housing upon progressing radially outward therefrom, and each of said generally upright legs extending radially inward toward said housing upon progressing upwardly from said lower leg toward said upper leg.

An air tool including a housing containing an air motor with a shaft rotatable about a longitudinal axis and connectable to an implement for working the surface of a workpiece, a power handle with upper and lower ends connected to said housing, an idle handle spaced angularly from said power handle and having top and bottom ends connected to said housing, a grip attached to and protruding from said housing with an elongate axis substantially aligned with said longitudinal axis of said shaft, said power handle including an air power inlet adjacent the lower end thereof, an air power outlet adjacent the upper end thereof and an air passage communicating therethrough from said inlet to said outlet, an air inlet port in said housing adjacent said upper end of said power handle, said air power outlet being aligned and communicating with said air inlet port, and a sealing element between said housing and said power handle sealing against the loss of air power between said power handle and said housing.

An air tool including a housing containing an air motor with a shaft rotatable about a longitudinal axis and connectable to an implement for working the surface of a workpiece, a grip attached to and protruding from said housing with an elongate axis substantially aligned with said longitudinal axis of said shaft, right and left handles having upper and lower ends, and upper and lower connections respectively securing said upper and lower ends of said handles to said housing, said handles being angularly spaced from each other by a preselected angle less than one-hundred eighty degrees (180.degree.) relative to said longitudinal axis, each of said handles including upper and lower generally radially extending legs and a substantially upright leg extending therebetween, said lower legs each having radially inward ends secured to said housing by said lower connections, and each of said generally upright legs extending radially inward toward said housing upon progressing upwardly from said lower leg toward said upper leg and having a longitudinal axis angled at approximately 15.degree. with respect to said longitudinal axis of said shaft.
