Abstract

Abstract A wheeled snow plow is provided and consists of a tubular frame having a laterally spaced pair of side portions, a rear portion and a V-shaped front portion to form a generally rectangular configuration, three wheel assemblies, one wheel assembly mounted to bottom center of the V-shaped front portion and each of the other two wheel assemblies mounted to bottom center of a respective side portion of the frame, a U-shaped handle connected pivotally to top center of the side portions of the frame so that the U-shaped handle will sit at a vertical angle with respect to the frame when in use, a V-shaped plow blade connected pivotally to the side portions of the frame so that the V-shaped plow blade will face frontwardly and be horizontal to the frame and a device for height adjusting the V-shaped plow blade with respect to the frame allowing for passage over rough and uneven terrain.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 356 words
A wheeled snow plow which comprises: (a) a tubular frame having a laterally spaced pair of side portions, a rear portion and a V-shaped front portion; (b) three wheel assemblies, one wheel assembly mounted to the bottom center of the V-shaped front portion and each of the other two wheel assemblies mounted to the bottom center of a respective side portion of the frame; (c) a U-shaped handle with a free end and a pivotal end; (d) means for connecting said pivotal end pivotally to the top center of the side portions of the frame so that the U-shaped handle will sit at a vertical angle with respect to the frame when it is in use and will pivot forwardly beyond said front portion of said frame when pivoted to a closed position when not in use; (e) a V-shaped plow blade; (f) means for connecting the V-shaped snow plow blade pivotally to the side portions of the frame so that the V-shaped plow blade will face frontwardly, be spaced from and circumscribe said V-shaped front portion; (g) means for height adjusting the V-shaped plow blade with respect to the frame allowing for passage over rough and uneven terrain; the means for connecting the U-shaped handle pivotally to the top center of the side portions of the frame comprises: (h) a pair of hinge stop members each hinge stop member affixed to the free end of the U-shaped handle, and (i) a pair of pivot pins each pivot pin placed through one of the hinge stop members and one of the side portions of the frame; the means for connecting the V-shaped plow blade pivotally to the side portions of the frame comprises: (j) a pair of spacers, each spacer having an aperture placed between one end of the V-shaped plow blade and the side of the front end of one of the side portions of the frame; and (k) a pair of pivot pins, each pivot pin placed through one end of the V-shaped plow blade, the aperture of the spacer and into the front end of one of the side portions of the frame.
Claim 2
Dependent Claim 356 words
A wheeled snow plow which comprises: (a) a tubular frame having a laterally spaced pair of side portions, a rear portion and a V-shaped front portion; (b) three wheel assemblies, one wheel assembly mounted to the bottom center of the V-shaped front portion and each of the other two wheel assemblies mounted to the bottom center of a respective side portion of the frame; (c) a U-shaped handle with a free end and a pivotal end; (d) means for connecting said pivotal end pivotally to the top center of the side portions of the frame so that the U-shaped handle will sit at a vertical angle with respect to the frame when it is in use and will pivot forwardly beyond said front portion of said frame when pivoted to a closed position when not in use; (e) a V-shaped plow blade; (f) means for connecting the V-shaped snow plow blade pivotally to the side portions of the frame so that the V-shaped plow blade will face frontwardly, be spaced from and circumscribe said V-shaped front portion; (g) means for height adjusting the V-shaped plow blade with respect to the frame allowing for passage over rough and uneven terrain; the means for connecting the U-shaped handle pivotally to the top center of the side portions of the frame comprises: (h) a pair of hinge stop members each hinge stop member affixed to the free end of the U-shaped handle, and (i) a pair of pivot pins each pivot pin placed through one of the hinge stop members and one of the side portions of the frame; the means for connecting the V-shaped plow blade pivotally to the side portions of the frame comprises: (j) a pair of spacers, each spacer having an aperture placed between one end of the V-shaped plow blade and the side of the front end of one of the side portions of the frame; and (k) a pair of pivot pins, each pivot pin placed through one end of the V-shaped plow blade, the aperture of the spacer and into the front end of one of the side portions of the frame.
Claim 3
Dependent Claim 168 words
A wheeled snow plow as recited in claim 1, wherein the means for height adjusting the V-shaped plow blade with respect to the frame comprises: (a) a rearwardly extending triangular plate having a central threaded aperture affixed within the V-shaped front portion of the frame; (b) an upright U-shaped member affixed to the rear center of the triangular plate; (c) a horizontal arm member having a transverse aperture pivotally affixed at the rear end to the upright U-shaped member; (d) a spring; (e) an adjustment screw placed through the aperture in the horizontal arm member through the spring and threaded into the threaded aperture in the triangular plate; and (f) a flow plate affixed at an angular vertical portion between the V-shaped plow blade, the plow plate engages the front end of the horizontal arm member so that by tightening the adjustment screw the V-shaped plow blade will move up while the V-shaped plow blade is prevented from moving downward when the wheeled snow plow is in use.
Claim 4
Dependent Claim 131 words
A wheeled snow plow as recited in claim 2, that further comprises a plow engaging plate having a V-shaped cut on one edge and affixed at the other end inwardly from the center of the U-shaped handle so that when the U-shaped handle is pivoted to a closed position for storage, the plow engaging plate will engage the pointed edge of the V-shaped plow blade preventing the V-shaped plow blade from moving; at least one hand grip placed onto the center of the U-shaped handle for better holding of the U-shaped handle; a carry handle affixed to the center of the rear portion outwardly from the frame so that a person can carry the wheeled snow plow when the U-shaped handle is pivoted to a closed position and not in use.
