Patent number: 8511895Abstract: A biodegradable lawn waste collection system is provided. The system generally includes a waste receiver, a shaping insert, and a handle. The waste receiver may comprise a mesh structure having a filling end and a sealing end. The mesh structure may be formed from a biodegradable polymer composition. The shaping insert is configured for removable reception within the filling end of the waste receiver. The shaping insert provides the waste receiver with rigidity and stability when filling the waste receiver with lawn waste. After the waste receiver has been filled with lawn waste, the shaping inert is removed and the filling end is secured, such as by tying a knot. The full waste receiver is then releasably attached to the handle, which enables the full waste receiver to be easily carried or dragged to a desired destination.Type: GrantFiled: June 25, 2010Date of Patent: August 20, 2013Assignee: Green Bag, LLCInventors: Brent Burchfield, Ryan Crisp, Eric Fickas, Paul Kolada, Michael Lorenz, Donald Meves, Shannon Staats, Herman Jones

Publication number: 20060101612Abstract: A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance is comprised of a base portion having a suction nozzle and a brush block having a plurality of vertical axis rotary agitators for cleaning bare floors. The rotary agitators are driven by an independent motor for agitating the floor surface. With the addition of an accessory hose and tools, the cleaning utility can be expanded to areas wherein the suction nozzle cannot normally reach such as behind the toilet, shower walls, and the grout between tile. While used in the capacity for cleaning bare floors, the floor care appliance can be moved between three modes by a rotating a member located on the upper housing. The first mode is dry mode, the second mode is wet scrub mode and the third mode is wet pickup mode. The accessory tools are stored in an accessory caddy that is placed freestanding over the suction nozzle and in front of the housing.Type: ApplicationFiled: November 17, 2004Publication date: May 18, 2006Inventors: Evan Gordon, Jeffery Louis, Kevin Scheifele, Jeffery Morgan, Brent Burchfield

Publication number: 20060101606Abstract: A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance includes a port for the connection of an accessory hose and wand for off the floor cleaning. A variety of cleaning implements can be attached to the wand for cleaning hard to reach bare surfaces such as tile and grout. The port includes a suction inlet, cleaning solution outlet, and an air turbine inlet for an air turbine pump which pressurizes the cleaning solution. A pivoting door seals the suction inlet, cleaning solution outlet, and air turbine inlet when the accessory hose and wand are not in use.Type: ApplicationFiled: March 24, 2005Publication date: May 18, 2006Inventors: Evan Gordon, Jeffery Louis, Kevin Scheifele, Jeffery Morgan, Brent Burchfield

Publication number: 20050167440Abstract: A coupling for connection of a tube comprises a coupling housing which includes a first end into which the tube is inserted, a clamping ring which is positioned in the coupling housing against a first conical surface, a sealing ring which is positioned in the coupling housing, and a return ring which is positioned in the coupling housing between the clamping ring and a second end of the housing adjacent a second conical surface that is tapered opposite to the first conical surface. The return ring is expandable and comprises a central aperture which is smaller than the external diameter of the tube. Accordingly, when the tube is pushed into the coupling housing and forced through the return ring, the return ring will expand and move along the second conical surface.Type: ApplicationFiled: July 14, 2004Publication date: August 4, 2005Inventors: Doug Huffer, Fred Lowery, Gary Petersen, Keith Gausmann, Samuel Marino, Gary Myers, Jamison Float, Jay Perkins, Steve Pever, Robert Hayes, Michael Kopezewski, Paul Hsu, Douglas Schaefer, Brent Burchfield, Jeffrey DeBord
