Patent ID: 7029240

Claim:
A portable air compressor assembly comprising: a generally tubular frame defining a parallelogram shape having a pair of substantially parallel side sections defining a forward end, a rearward end, and an enclosed spatial volume; a plurality of operating components supported by said tubular frame and completely contained within said enclosed spatial volume; an axle slidably disposed through said side sections proximate said rearward end; a curved and angularly extending tubular portion of said frame proximate said frame rearward end operably forming a frame rotation stop, said curved and angularly extending tubular portion contacting a ground surface when said compressor assembly is rotated about said axle to said rotation stop, thereby limiting further rotation of said compressor assembly; and a center-of-gravity of said assembly positioned forward of a vertical axis defined through the axle in both the normal operating position and when said compressor assembly is rotated about said axle to said rotation stop.
