  • Patent number: 8479776
    Abstract: A flexible garden hose having an inner tube member made from elastic material and an outer tube member made from a non-elastic material. The inner tube member is secured to the outer tube member only at an inlet coupler and an outlet coupler. The inlet coupler is constructed to secure to a water supply provided from a conventional household water spigot. The outlet coupler is coupled to a flow restrictor allowing the inner tube member to equalize in pressure with pressurized water received from the water supply. Pressurized water expands the elongated inner tube member longitudinally along a length of the inner tube member and laterally across a width of the inner tube member thereby substantially increasing the length of the hose to an expanded condition wherein the hose contracts to a substantially decreased length when there is a decrease in pressurized water.

  • Patent number: 8414670
    Abstract: A dust-sucking and air-cleaning composite structure is provided with a dust-sucking body and an air-cleaning body. The top surface of the air-cleaning body is provided with a vertically opening cavity. The cavity is recessed downward toward the interior of the air-cleaning body and has an opening facing upwardly. The inner profile of the cavity corresponds to the outer profile of the dust-sucking body, thereby allowing the dust-sucking body to be movably inserted into the cavity to be electrically coupled to the air-cleaning body.

  • Patent number: 8296897
    Abstract: The present invention relates to a central vacuum cleaning system for vehicles. The unit comprises a vacuum generating alternating current motor, a built-in direct current to alternating current inverter and a removable dirt cup containing a filter and screen. The unit has a built-in in-take port, which has an auto switch that turns the unit on when the vacuum hose is plugged in and shuts the unit off when the vacuum hose is unplugged. The unit also has a remote in-take and remote auto switch capability so you can plug the vacuum hose into a more convenient location in the interior of the vehicle. The unit can be mounted horizontally or vertically. The unit can be installed in any vehicle consisting of a 12-volt direct current battery. The vehicle does not need to have an alternating current inverter installed separately to operate.

  • Patent number: 8291941
    Abstract: A hose which automatically expands longitudinally and automatically expands laterally upon the application of a fluid pressure is disclosed. The hose can automatically expand longitudinally up to six times its unexpanded or contracted length. Upon release of the fluid pressure within the hose, the hose will automatically contract to a contracted condition. The hose includes an inner tube made from an elastic material and an outer tube made from a non-elastic material. The inner tube is positioned concentrically within the outer tube in both a contracted condition and an expanded condition. The outer tube is secured to the inner tube only at a first end of the inner and outer tubes and at a second end of the inner and outer tubes. The outer tube moves laterally and longitudinally with respect to the inner tube when the tubes are transitioning between a contracted condition and an expanded condition.

  • Patent number: 8056180
    Abstract: A mobile leaf blower includes a main blower assembly driven by an engine or motor. The blower has a deflector box at the blower outlet with deflector plates which enable the air flow to be either directed laterally and forwardly of the blower unit or to a flexible blower tube attached to the unit. The operator may either cause the air flow to flow through the flexible blower tube or forwardly and laterally of the blower unit along the ground. When not in use, the flexible blower tube can be wound around a hose reel attached to the main handles of the ground blower unit.

  • Patent number: 8011059
    Abstract: An air duct comprises a duct wall bounding an airflow channel that extends through the air duct along a flow path. The airflow channel has a plurality of cross-sections that are bounded by the duct wall and that are perpendicular to the flow path. A first one of the cross-sections has an aspect ratio that is less than two. A second one of the cross-sections has an aspect ratio that is greater than four and a minimum dimension that is less than three-quarters of an inch. A third one of the cross-sections has an aspect ratio that is less than two. The second cross-section is positioned between the first and third cross-sections along the flow path. The air duct channels air beneath a door, thereby allowing a vacuum or blower tool to operate in one room while the vacuum or blower device operating the tool operates in a different room.

    Abstract: An auxiliary vacuum device for a central vacuum cleaning system is location specific and comprises housing mountable externally on an inlet of a mounting plate of the system, a dedicated flexible concertina hose is provided on the device and a cleaning tool mounting probe is registrable with a docking station. When the probe is removed from the docking station, a lever may be moved in first and second directions to selectively activate and deactivate the motor of the central vacuum cleaning system and the device. When the probe is parked in the docking station the probe moves the lever in one of the directions and holds the lever in a deactivated configuration, thus deactivating the motor and the device and preventing activation thereof.
