20100071151 | Removable Internal Air Diffuser - Disclosed herein is a vacuum cleaner having a housing defining first and second ports. The vacuum cleaner also includes a cap assembly. The cap assembly includes a cap head to close the first port such that airflow is directed via a flow path to the second port, a sound-influencing material, the sound-influencing material removably held to the cap head and disposed within the flow path to reduce noise effected by the airflow. The flow path is configured to cause the airflow to pass through the sound-influencing material and the flow path to the second port. The sound-influencing material is removable to allow cleaning of the sound-influencing material. The sound-influencing material may include a reticulated foam roll disposed in the frame to diffuse the discharge airflow. | 03-25-2010 |
20110107549 | VACUUM DEVICE WITH POSITIVE PRESSURE TANK - In a device that uses the tank from a conventional vacuum cleaner, the tank is under positive pressure. A cap fits over a tubular element inside the tank and closes the conventional air inlet. The cap has a peripheral wall that extends between a solid back and a front radial rim, and interior axial ribs. The lid is held by a latch that has an element that pivots with respect to the tank and the lid, and a clasp that has a bent arm. A tensioner pulls the bent arm. The tensioner has a threaded rod that extends from a handgrip though a hole in the pivoting element. A nut on the clasp receives a threaded end of the threaded rod, enabling the handgrip to be used to tighten the clasp. An outer wall of the latch is disposed outwardly of the threaded rod and the bent arm. | 05-12-2011 |
20110109177 | MOTOR ASSEMBLY WITH SWITCH MODULE - A new motor assembly uses a switch module to facilitate the assembly of an electric motor. The switch module can be prefabricated, and is connected to a terminal block on the motor by plug and socket connectors on the terminal block and on a terminal end of the module. The switch module is pre-wired with a power inlet and a switch, eliminating the need for a worker on the motor assembly line to make difficult electrical connections to a traditional terminal block. The switch is arranged in a switch housing that fits within an extension on the motor housing. An interior support wall on the housing fits within a channel between the switch housing and the rest of the switch module, helping to hold the assembly in position. The power inlet is positioned laterally outward from the terminal end and laterally inward of the switch. | 05-12-2011 |
20130007979 | Portable Combined Toolbox and Vacuum Cleaner - Mating connectors enable a vacuum cleaner section to be releasably attached to a toolbox section. The connectors include a downward-facing tongue that fits in a corresponding horizontal slot. The tongue has a vertical slot that corresponds with a vertical flange adjacent the slot. An interacting tab and slot prevent the vacuum cleaner section from being removed from the toolbox section when a closeable top on the toolbox section is closed. The two sections attach in a position in which upright side walls on the vacuum cleaner section align with the upright sides on the toolbox section, and an extended horizontal work surface is formed by portions of the hinged top on the toolbox section and the vacuum cleaner section. A handle on the vacuum cleaner section can form part of the horizontal work surface, which has parallel lateral grooves with co-linear segments on opposite sides of a recessed channel. A wheeled version has a handle hinged to a mount and a pocket that encircles and supports the vacuum cleaner section. Another version has a handle that retracts into the recessed channel and is arranged to support the top against the ground when the top is fully open. | 01-10-2013 |
20130283563 | FILTER SHAKER - A filter shaker for a filter assembly disposed in a vacuum includes a housing that removably mounts to the filter and/or a support for the filter and a vibrator assembly carried by the housing. When actuated, the vibrator assembly vibrates the filter to clean particulate matter from the filter. The vibrator assembly includes a motor that drives an eccentric and an actuator that periodically impacts against a portion of the housing to cause the vibrations. The housing includes a mounting assembly for mounting the filter shaker to the cage and/or filter in an operative position and a locking assembly for locking and unlocking the filter shaker in the operative position to prevent the filter shaker from vibrating off. In the operative position, the filter shaker covers an open end of a tubular filter and thereby forces air to be directed through filter material of the tubular filter. | 10-31-2013 |
