Patent number: 8714607Abstract: A hand shovel assembly facilitates emptying of the shovel with minimal lifting. The assembly includes a shaft having an upper end and a lower end. A pan is coupled to the lower end of the shaft. The pan has a bottom wall, a back wall which extends upwardly from the bottom wall, and a pair of side walls coupled to and extending forwardly from opposite ends of the back wall defining an interior space of the pan. An upper wall is coupled to the pan over the bottom wall. A motivator is coupled to the pan between the bottom wall and the upper wall. The motivator selectively urges the upper wall away from the bottom wall wherein the upper wall is configured to urge material in the interior space of the pan out of the interior space.Type: GrantFiled: February 27, 2013Date of Patent: May 6, 2014Inventor: Lionel A.

Publication number: 20130119684Abstract: A manually operated shovel having a blade and a plurality of tooth members is provided. The tooth members of the shovel provide individual points of contact between the shovel blade and material, such as earth, when the blade of the shovel is pressed into the material. The tooth members provide a mechanical advantage that focuses the pressure applied to the shovel by the operator so as to penetrate material more easily than traditional uniformly bladed shovels.Type: ApplicationFiled: November 12, 2012Publication date: May 16, 2013Inventor: LOUIS CEJA

Patent number: 8061745Abstract: A multi-purpose spade includes a central plate, first and second edge plates, and a retreating crescent blade. The central plate is generally concave. The retreating crescent blade is formed along the tip portions of the central plate and the first and second plates. The inner edge portions of the first and second plates are connected to corresponding side portions of the central plate with a predetermined angle so as to form two crest portions on the front surfaces along the side portions of the central plate. The multi-purpose spade may further comprise an extending blade configured to be connected to the retreating crescent blade.Type: GrantFiled: June 5, 2009Date of Patent: November 22, 2011Inventor: Hyun C.

Patent number: 6892419Abstract: The scalloped edge dustpan is eliminates the line of dust or debris that is often left on the floor when dust or debris is swept in to a conventional, straight-edge dustpan. is a dustpan in which the front or leading edge of the base or blade has is formed with a continuous series of semicircular segments or protrusions forming a scalloped edge. The scallops may be beveled so that the scalloped edge tapers downward towards the front of the base. The dustpan may be formed with the base and the leading edge formed as a single piece of material, or the scalloped edge may be formed as a strip attached to the front of a dustpan blades leading edge by adhesive or fasteners.Type: GrantFiled: March 3, 2004Date of Patent: May 17, 2005Inventor: John F. Duprey

Publication number: 20030025344Abstract: An snow removal tool having an insert-molded wearstrip is disclosed. According to one embodiment of the present invention, the tool includes: a plastic blade portion and a wearstrip attached to each other by insert molding. Insert molding is performed by placing the wearstrip, which has one or more openings therethrough, in a recess of a mold cavity. Plastic is injected into the mold cavity and flows through the openings in the wearstrip. Upon solidification of the plastic, the final molded product has a cutting edge of the wearstrip protruding from a front edge of said snowtool. Preferably the wearstrip is made from galvanized steel and has a fold or ridge across it to increase stiffness of said snowtool in bending.Type: ApplicationFiled: August 1, 2001Publication date: February 6, 2003Inventors: Jan E. Schultice, Thomas Parker

Patent number: 6497439Abstract: A shovel includes a base panel portion, a shovel member secured on the base panel, a handle secured to the shovel member, and a blade secured to the bottom and front portion of the base panel and extended forward beyond the base panel for engaging with material such as the snow. The shovel member and the base panel may be made of lighter metal or plastic or composite materials, for decreasing the weight of the shovel and for reducing the manufacturing cost for the shovel. The blade is made of stronger metal materials for increasing the working life of the shovel.Type: GrantFiled: December 4, 2001Date of Patent: December 24, 2002Inventor: Wen Li Guo

Patent number: 5845949Abstract: A snow shovel comprises a longitudinally elongated handle and a curved generally rectangular blade receiving an end of the handle on the convex surface of the blade. The blade is curved respecting a transverse axis and includes a scraper support edge extending transversely to the handle, defining a blade extremity remote from the handle. The blade further includes an upstanding lip on its periphery not defined by the scraping edge, extending transversely to the blade in the direction of the blade concave surface, with the portion of the lip being parallel to the handle, preferably being canted inwardly towards the handle. The blade further has upstanding triangularly configured reinforcing gussets formed in the blade and protruding from the blade concave surface, generally parallel with the handle, with the gussets having heights and widths at least initially increasing with distance from the scraping edge.Type: GrantFiled: January 11, 1997Date of Patent: December 8, 1998Inventor: Peter Vosbikian

Patent number: 5727830Abstract: A snow shovel is presented capable of reducing the amount of work needed to clear heavy and packed snow. The shovel is composed of a handle, shaft and scoop each of molded plastic. The invention comprises a scoop with a front edge and two stainless steel leading edges-angled at approximately 160 degrees. This orientation results in a snow shearing force as the scoop is moved through heavy and packed snow reducing the amount of energy required for the removal of heavy and packed snow.Type: GrantFiled: February 24, 1997Date of Patent: March 17, 1998Inventor: Randall S. Asher

Patent number: 5039151Abstract: A snow shovel is disclosed which combines the straight transverse front or leading edge with the shape of a shallow scoop which forms a major part of the front face of the scoop of the shovel. The advantage is in that the shoveled snow tends to accumulate at the center of the scoop thus reducing the spill over the sides of the shovel and also facilitating the manipulation of the shovel filled with snow. The geometry of the handle is designed to facilitate the manipulation of the shovel.Type: GrantFiled: September 19, 1989Date of Patent: August 13, 1991Inventor: Edgar H. Davis
