  • Publication number: 20120321488
    Abstract: A wheelbarrow compressor has a resting position and a transport position. First and second reservoirs contain a compressed fluid, and the second reservoir is fluidly separate from the first reservoir. The second reservoir is positioned above the first reservoir in a generally vertical direction when the wheelbarrow compressor is in the resting position. A handle assembly is attached at a rear end of the wheelbarrow compressor, and a wheel assembly attached at a front end of the wheelbarrow compressor generally opposite the rear end. A pump is fluidly connected to the first and second reservoirs for providing the compressed fluid thereto, and a motor is operatively connected to the pump to drive the pump. The pump and motor are positioned adjacent the first and second reservoirs in a generally horizontal direction when the wheelbarrow compressor is in the resting position.

  • Publication number: 20110314628
    Abstract: A vacuum extension wand accessory storage assembly for use with a wet/dry vacuum that improves user access to the wands while simultaneously preventing accidental loss or dislodgement of the wands when the vacuum is not in use. The wand storage design includes the combination of a channeled, shaped surface formed in the bottom of the vacuum collection drum and an accessory attachment system on the bottom of the vacuum appliance having both front and rear securement assemblies which in combination secure the extension wands in place below the collection drum of the vacuum appliance in the event of vacuum transportation, lifting, or storage.

  • Patent number: 7798057
    Abstract: A cooking device comprises a cooking surface and a wall structure that extends away with respect to the cooking surface. Examples of the cooking device include a closure configured to be moved with respect to the wall structure from a first position to a second position. Access to the cooking surface is provided when the closure is oriented in the first position and the closure is configured to cooperate with the wall structure to define a cooking chamber when the closure is oriented in the second position. A handle can be attached to the closure, wherein the closure is configured to move from the second position to the first position by moving the handle away with respect to the wall structure. In addition or alternatively, the cooking device may include a rotisserie device with an arm configured to move from a retracted position to an extended position with respect to the wall structure.
