  • Patent number: 9808135
    Abstract: A hand held vacuum cleaner unit and docking assembly for a central vacuum system is shown. The hand held vacuum cleaner has a handle, a suction nozzle, a trigger switch to turn on a battery powered suction motor and an outlet port. The docking assembly fits into a central vacuum cleaner mounting plate, and provides a cradle to store the hand held vacuum cleaner. Recharging contacts, a latch mechanism, seals and an intake port are provided on the docking assembly. When the hand held unit is in the docking assembly it may be electrically charged, and emptied of dirt and debris by activation of the central vacuum system. The docking assembly also includes an access port for a conventional central vacuum hose.

  • Patent number: 9523509
    Abstract: A passive vent for venting a building enclosure having an opening in a roof portion, the vent being adjustable for mounting on roof portions of different slopes. The vent has a base pivotally attached to a vent structure with a pair of pivot joints. The vent structure has a collar attached to a vent body having a cover. At least one gas permeable screen is positioned on the vent body between the cover and the collar. The base comprises a lower attachment structure for attaching the base to the roof portion over the opening. An aperture through the lower attachment structure permits gas to pass in to and out of the opening in the roof portion through the base. A wall including a pair of opposed curvilinear wall sections surrounds the aperture. The pivot joints define a pivot axis about which the vent structure pivots along a range of angles relative to the base.

  • Publication number: 20160215500
    Abstract: A ridge vent for venting air through a ridge opening of a roof. The ridge vent has an elongated body having spaced apart outer attachment flanges to partially extend down a sloped roof deck on either side of the ridge opening a top surface on said elongated body extending between and connecting the outer flanges. It also has upwardly facing ventilation openings formed a top of the elongated body to permit air to vent though the body; and at least one weather deflecting baffle extending below the upwardly facing ventilation openings to deflect water passing through the ventilation openings away from the ridge opening and onto the roof deck adjacent to and below the ridge opening. A method of installing the vent is also shown.
