Publication number: 20130167413Abstract: This versatile and revolutionary snow removal tool operates to almost effortlessly displace the snow from sidewalks and other flat surfaces by routing the snow to either side of the “flared” plow blade clearing pathway the width of the MINI-PLOW varying in width from approximately 42-44 inches. The MINI-PLOW is lightweight and has a specially curved and angled blade with no obstruction on either side allowing unobstructed flow of snow simultaneously to the right and left of the blade. After a slight and short upward direction, the grooves on the blade are sharply angled in a horizontal pattern (as opposed to the conventional vertical pattern); thus, allowing the snow to be routed outward from the center of the blade. The MINI-PLOW is fitted with parallel elongated shafts for maximum stability. It has an angled-bar handle at the top and connecting the parallel shafts for each hand, for added stability.Type: ApplicationFiled: January 19, 2011Publication date: July 4, 2013Inventor: Sherron L.

Publication number: 20110258889Abstract: A snow, slush, and water removal device comprising a blade with top and bottom working edges. The blade can be straight, curved, or V-shaped when viewed from above or from the side. The bottom edge of the blade is comprised of a flexible material. The reverse side of the blade contains attachment points and bracing for the main long handle pole, the main handle being connected at the first end to the reverse side of the blade. The novel combination of features provides superior results both in terms of less energy required, and faster and safer removal of snow, slush, water, or other matter.Type: ApplicationFiled: April 22, 2011Publication date: October 27, 2011Inventors: Kurt Settembre, Richard Settembre

Publication number: 20110258888Abstract: A snow shovel device is provided that allows a user to remove snow from pathways. The shovel comprises a “V” shaped blade surface attached to a telescoping main shaft, which is fixedly attached to a push handle. The “V” shape of the blades provides a plow device to efficiently pierce deep snow in order to create a clear pathway. The main shaft may be pivoted in a plurality of directions to allow the user to adjust the yaw angle of the blade surface as well as the pivot angle of the main shaft with respect to the blades. Adjustment of the pivot angle and shaft length reduces strain on the user as snow is displaced.Type: ApplicationFiled: April 15, 2011Publication date: October 27, 2011Inventor: Al Swenson

Patent number: 6269558Abstract: An adjustable snow plow shovel including a T-shaped handle comprised of a horizontal gripping member and an elongated vertical shaft member. The horizontal gripping member has opposed ends and a midpoint. The elongated vertical shaft member has an upper end and a lower end. The upper end is secured to the midpoint of the horizontal gripping member. The lower end has a pair of support brackets extending outwardly therefrom in opposite directions. The support brackets each have an angularly disposed outer end having an aperture therethrough. A pair of plow blades are pivotally coupled with a plow blade support. The plow blade support is secured to the lower end of the elongated vertical shaft member of the T-shaped handle. Each of the plow blades has a plurality of linearly aligned apertures therethrough on a horizontal plane in a spaced relationship.Type: GrantFiled: September 8, 2000Date of Patent: August 7, 2001Inventor: Dante A. Alexander

Patent number: 5974703Abstract: A drag-along snow apparatus for use upon a snow covered ground surface. The snow plow apparatus includes a first substantially planar and elongate extending member and a second substantially planar and elongate extending member which are interconnected along a common vertical edge and which form, in combination, a substantially V-shaped configuration. First and second planar and horizontally arrayed cross members extend between the first and second elongate extending members and brace the connection between the elongate extending members. A length of rope is secured to the plow apparatus via a looped end which extends successively through a first rope support aperture located at a forward end of said elongate extending member and a second rope support aperture located at a forward end of said second elongate extending member. The rope permits a user to drag the plow apparatus along a snow covered ground surface.Type: GrantFiled: January 21, 1998Date of Patent: November 2, 1999Inventor: Robert N. Cadarette

Patent number: 5791072Abstract: An adjustable snowplow designed to remove snow and other materials from various surfaces by pushing the snowplow along the surface. The adjustable snowplow has a handle attached to twin, mirror imaged, curved, blades which are adjustably joined to each other at their respective inner end to form a unitary plow blade. The width or footprint of the plow can be adjusted by angling the blades closer or further from each other to plow a narrower or wider path depending on the task at hand. The symmetry of the blades about the length of the attached handle causes snow and other materials pushed by the plow to be distributed equally to either side of the plow.Type: GrantFiled: January 21, 1997Date of Patent: August 11, 1998Inventor: Michel Schbot

Patent number: 5528793Abstract: A multipurpose squeegee intended for use in removing snow, slush, water and other liquids from automobile surfaces and various other surfaces. The squeegee comprises a downwardly open U-shaped base within which are secured two layers of polyethylene foam or similar material. The foam extends slightly beyond the ends of the base to prevent damage to adjacent surfaces. A handle is attached to the base. A generally Y-shaped deflector with the upper arms thereof formed as curved wings is attached to the upper surface of the base to deflect excess material in the direction that the squeegee is being moved.Type: GrantFiled: July 10, 1995Date of Patent: June 25, 1996Inventor: Michel Schbot
