  • Patent number: 6108858
    Abstract: A floor mounted sweeping suction inlet is provided with a door that carries a user-activated portion by which the door may be opened by contact from a foot. This makes it unnecessary for the householder to bend over to activate the vacuum-operated waste collection system. The vacuum source can be turned-on automatically by opening the door by the presence of a door-activated electrical switch. An adapter converts the floor-mounted vacuum opening to a standard circular opening for receiving a vacuum hose and wand.

  • Patent number: 6052839
    Abstract: An offset toilet flange for connecting an outlet of a toilet bowl with waste water drain conduit is shown. The toilet flange includes an outer flange having an upper surface and a lower surface. The outer flange has at least two generally opposed first apertures which extend through the flange between the upper surface and the lower surface for retaining fasteners for securing the flange to an underlying surface. At least a portion of the lower surface lies against the underlying surface. The flange also includes at least two second apertures extending from the lower surface to the upper surface for retaining fasteners connecting the flange to the toilet bowl. A seat is also provided for a toilet bowl seal, the seat being located inside of the flange and being circular in plan and inwardly curved in profile.

  • Patent number: 5886299
    Abstract: This invention relates to an inlet valve assembly for central vacuum systems. In particular, this invention relates to an inlet valve assembly including an inlet face plate, a mounting plate, having a deformable mounting flange, and an electrical receptacle integrally formed with a high voltage wire. In some uses, the inlet valve assembly also can include a low voltage wire which can be used to complete a low voltage circuit to initiate a central vacuum motor. The mounting plate can accommodate the electrical receptacle in a temporary position and the inlet face plate can rear mount the receptacle into a locked position where the receptacle is securely attached to the inlet face plate. In this manner, the receptacle may be mounted to the inlet face plate even though one end of the high voltage wire is already wired into an electrical box.

  • Patent number: 5664375
    Abstract: An exterior ventilation device having a main body with an upstanding perimeter wall and an attachment flange extending outwardly from the upstanding perimeter wall. A plurality of louvers extend across the body adjacent to the other end of the perimeter wall each of the louvers being sloped downwardly and outwardly. A trim ring is attachable to the main body and defines a cavity between the attachment flange and the skirt of the trim ring into which siding may be inserted. The body is provided with a water directing rib to direct any water running down the body from the back of the body towards the front of the body and thus outside of any cladding material located in the cavity between the trim ring and the attachment flange. In one embodiment the water directing feature is a rib and in another embodiment the feature is a groove.

  • Patent number: 5591080
    Abstract: An exhaust vent cover for closing the exhaust vent when the exhaust vent is not in use is shown. The exhaust vent cover includes a peripheral flange for attaching the cover to a surface and a continuous hollow body extending upwardly from the flange and having an open front as well as an air passageway communicating with this open front. The continuous hollow body further includes an overhang extending beyond the open front, a grill covering the open front to prevent access to the inside of the continuous hollow body, and a valve located inside the hollow body across the air passageway. The exhaust vent cover also includes a sloped upper surface to prevent the valve from being blown open.
