Patent number: 7320490Abstract: An impact handle for a shovel and other tools to assist the user or laborer in digging and/or moving material such as dirt or snow, or other compacted materials. An impact handle with a shovel attachment would have similar physical features as generic shovels on the market today. However, the impact handle includes an impact generator within the handle. As a user or operator applies his/her foot-pressure on the foot actuator located at the top of the scoop or blade, the impact generator using electro-magnetic principles produces impulses of 1 to 10 hertz of downward blows. These impulses reduce the effort required by the operator to force the tool scoop or blade to penetrate the material being excavated. The impact handle dramatically reduces time required to complete hand excavation projects. The impact handle can also be used, but is not limited to, to reduce the time required for chiseling, scraping, prying, nail pulling and carpet-stretching.Type: GrantFiled: September 12, 2005Date of Patent: January 22, 2008Inventor: Ray James Yakimchuk

Patent number: 6089632Abstract: The subject invention provides a post hole digger which facilitates the digging of deep uniform diameter post holes. Th post hole digger accomplishes this by crossing the handles to close the shovel blades. This allows the handles to stay within the diameter of the hole opening, removing the need to increase the diameter of the hole opening as the depth of the hole is increased.Type: GrantFiled: October 4, 1999Date of Patent: July 18, 2000Inventor: Porter T. Pickren

Patent number: 6027153Abstract: A garden trowel includes a handle, a blade, and a connection member interconnecting the handle and the blade. The handle has a length which accommodates the use of two hands. The blade includes a body portion and a stem portion. The body portion of the blade has a beveled edge. The stem portion of the blade is bent and is attached to the connection member. The bent stem portion of the blade effectively offsets the blade from the handle. The handle of the trowel is formed in an offset manner along a longitudinal axis. More particularly, the handle is rotationally offset in a range between about four and about six degrees with respect to a vertical plane intersecting the longitudinal axis (to the right for a right handed trowel and to the left for a left handed trowel). The handle includes an increasing, graduated size of the handle that extends from a forward end of the handle to a rear end of the handle. The forward end of the handle is connected to the blade via the connection member.Type: GrantFiled: January 23, 1998Date of Patent: February 22, 2000Inventor: Jeffrey J. Marshall

Patent number: 6006403Abstract: A resilient cushioning grip for use on various handles which is readily applied, removable, or transferable to another handle without disassembly of connected parts integral with the handles. The grip provides a firm, safe surface for the user's hands eliminating the need for gloves or resin powder. The grip preferably comprises an extruded resilient pad, rectangular in shape having a hook and loop fastener system. The grip is wrapped around and securely attached to the handle, such as the bar of weight lifting equipment and handles of bicycles, health care equipment, lawn and garden tools, hand tools and other items.Type: GrantFiled: August 3, 1998Date of Patent: December 28, 1999Inventor: Victor Battiato

Patent number: 6003915Abstract: An improved snow shovel with a telescoping handle comprised of a plurality of tubular elements, the outermost element having a grip at one end and the innermost element having a tip at the opposite end; a detaching blade, and a permanently mountable secondary tip and manually mounting removable basket. With the blade removed, the handle telescopes to a length greater than seven feet thus converting into a singular rod or snow probe used to feel or probe for buried victims in avalanche debris. When the handle is retracted, the blade is attached and the outermost telescoping element extends outwardly to a locked position. This increases leverage when digging to recover avalanche victims. With the blade detached and the handle extended, the secondary tip secures to the primary tip on the innermost element. This allows the snow basket to be mounted. The handle is then adjustable to any one of several positions for use as a spare ski pole when necessary.Type: GrantFiled: September 25, 1995Date of Patent: December 21, 1999Inventor: Paul Douglas Bierman

Patent number: 5984393Abstract: A shovel assembly having a shovel head and a handle shaft. The handle shaft has a first end and a second end, wherein the first end of the handle shaft propagates along a longitudinal axis. A pivot joint is interposed between the shovel head and the handle shaft. The pivot joint selectively enables the shovel head to rotate about the longitudinal axis. The pivot joint is configurable into three distinct conditions. In a first condition, the pivot joint rigidly couples the shovel head to the handle shaft. In a second condition, the pivot joint enables the shovel head to rotate around the longitudinal axis of the handle shaft in a first direction. Lastly, in a third condition, the pivot joint enables the shovel head to rotate around the longitudinal axis of the handel shaft in a second direction. A manual control is provided on the shovel for selectively configuring the pivot joint between the first condition, the second condition and the third condition.Type: GrantFiled: June 29, 1998Date of Patent: November 16, 1999Inventor: Rodney H. Washington

Patent number: RE36588Abstract: Disclosed is an improved snow shovel having a graphite in-laid polyethylene blade with outwardly propagating reinforced ribs providing a flex resistant blade of minimal thickness. A shaft of the shovel is constructed of a low cost steel pipe covered with a polyethylene sleeve with knurled grip surfaces. The sleeve conforms to the pipe diameter upon application of heat during manufacture. A one-piece handle is attached to the free end the shaft. For storage purposes a cutout is provided on a top edge of each shovel allowing nesting of similarly shaped shovels. A straight blade shovel and a pusher type shovel are two embodiments disclosed herein.Type: GrantFiled: August 1, 1996Date of Patent: February 29, 2000Assignee: Suncast CorporationInventors: Thomas A.
