  • Patent number: 10286778
    Abstract: Outdoor equipment, such as a lawn mower, includes a frame, a riding area, front wheels, and a wheel assembly. One wheel assembly includes an outer plate, a rotating bracket pivotally connected to the outer plate, a primary wheel supported by the rotating bracket, and a secondary wheel supported by the rotating bracket. The rotating bracket is rotatable about a pivot axis, the primary wheel is axially offset from the pivot axis, and the secondary wheel is axially offset from the primary wheel and from the pivot axis. In use, the rotating bracket consistently provides two points of contact (one by the primary wheel and another through the secondary wheel) by rotating automatically about the pivot axis due to gravity and forces transferred through the wheels. This enhanced distribution of forces may provide a more comfortable, cushioned riding experience.

  • Patent number: 10214869
    Abstract: A snow thrower including an auger, a chute, a prime mover, and first and second drive wheels powered by the prime mover configured to be driven at variable speeds. The snow thrower further includes a user interface including a left hand grip and a right hand grip configured to pivot within an angular range of motion relative to an axis of rotation to indicate a direction and a magnitude of a desired turn, a steering sensor, and an electronic control unit configured to control operation of the first and second drive wheels. The user interface is pivoted in a first direction about the axis of rotation, the first and second bumpers are configured to contact the first and second force sensors to apply forces to the first and second force sensors to send first and second signals indicative of the forces to the electronic control unit.

  • Publication number: 20190015853
    Abstract: A spray gun for use with a pressure washer includes a spray gun body, an inlet, a primary flow path for conducting a primary fluid flow, a secondary flow path for conducting a secondary fluid flow, and an inlet flow path for receiving a flow of pressurized water from the pressure washer via the inlet. The inlet flow path directs the pressurized water into the primary flow path. The spray gun further includes multiple chemical containers carried on the spray gun body, each chemical container configured to contain a different chemical, and a selector valve movable among a number of positions to fluidly couple one of the chemical containers with the secondary flow path.

  • Patent number: 8567846
    Abstract: A vehicle includes a vehicular frame and a utility bed coupled with the vehicular frame. The utility bed includes a bed frame and a seat. The seat includes a seat bottom and a seat back. The seat back is movable between a stowed position and a deployed position. The seat back includes an upper back support and a lower back support. The lower back support is movably coupled with the upper back support and is movable between a passenger support position and a stored position.
