Handle and exhaust duct coupling assemblies for floor care machines are disclosed. In one embodiment, an exhaust duct coupling assembly (500) includes a first duct (306) having an outer surface with an external thread (508) disposed thereon and a locking tab (510) projecting outwardly therefrom. A second duct (310) is slideably engaged into the first duct (306), and a flexible seal (512) is disposed about the second duct (310) proximate an end of the first duct (306). A collar (502) having a hole therethrough is disposed about the second duct (310) and threadedly engaged with the end of the first duct (306). The collar (502) presses the seal (512) into an approximately sealing engagement against the second duct (310) and the end of the first duct. The collar (502) includes a locking surface (509) frictionally engaged with the locking tab (510) and inhibiting a disengaging movement of the collar (502). Alternately, the locking surface (509) of the duct coupling assembly (500) may be an annular surface disposed on an inner surface of the collar (502), or may be disposed on an end surface of the collar (502). In yet another embodiment, a handle coupling assembly (600) includes a receiving member (308) having an outer surface with an external thread (614) disposed thereon and a plurality of bendable members (612) projecting outwardly therefrom and at least partially surrounding a receiving space (613). A handle tube (306) is disposed within the receiving space (613). A collar (602) is disposed about the handle tube (306) and threadedly engaged with the external thread (602). The collar (602) bends the plurality of bendable members (612) into engagement against the handle tube (306), thereby securing the handle tube (306) into position.
摘要:
An apparatus and method for transporting a flow of air and particulates through a vacuum cleaner. The apparatus can include an airflow propulsion (200) device that draws the flow through an intake aperture (111) and propels the flow through two upwardly-extending conduits (30) toward a filter element (80) housed in a filter housing (70). The conduits (30) can have generally smooth internal walls and a combined flow area less than the flow area of the intake aperture (111) to accelerate the flow upwardly toward the filter element (80).

An integral vacuum cleaner bumper (100) is provided according to an embodiment of the invention. The bumper (100) includes a bumper shell (101) formed of an at least partially resilient material and includes an inner surface (107) that mates to the vacuum cleaner chassis (192) and an outer surface (108). The bumper shell (101) is affixed to the vacuum cleaner chassis (192) as an integral component of the vacuum cleaner and the outer surface (108) of the bumper shell (101) becomes a portion of an outer surface of the vacuum cleaner. The bumper (100) further includes one or more cavities (103) formed along a bottom edge region (102) of the bumper shell (101), one or more corresponding magnets (110) designed to fit into the one or more cavities (103), a backing plate (114) including one or more fastener apertures (116), and one or more fasteners (118) that pass through the one or more fastener apertures of the backing plate and affix the backing plate to the bumper shell.

An airflow sensor system (100) for monitoring air inlet airflow and air outlet airflow of a vacuum cleaner is provided according to an embodiment of the invention. The airflow sensor system (100) includes a vacuum cleaner air duct (101), a bypass tube (110) connected to the air duct (101), and an airflow sensor (111) positioned at least partially in the bypass tube (110). The airflow sensor (111) is configured to generate a normal voltage differential range when the bypass tube airflow is within a predetermined normal airflow range, configured to generate an input blockage voltage differential range when the bypass tube airflow is greater than the predetermined normal airflow range, and further configured to generate an output blockage voltage differential range when the bypass tube airflow is less than the predetermined normal airflow range.
摘要:
Handle assemblies (320, 420, 520, 620, 720) for floor care devices (200), and methods for using the same, are disclosed. In one embodiment, a handle apparatus (320) includes a main member (330) partially surrounding a cord retaining space (350) that is adapted to receive a plurality of portions (352) of a power cord (328) of the floor care device (200). A retaining member (340) is moveably attached to the main member (330), and includes a retaining surface (344) that is positionable proximate the cord retaining space (350). In a first or 'retaining' position (347), the retaining surface (344) retains the plurality of power cord portions (352) within the cord retaining space (350), and in a second or 'releasing' position (349), the retaining surface (344) releases the plurality of power cord portions (352) from the cord retaining space (350). In alternate embodiments, the retaining member (340) may be rotatably, pivotably, or slidably attached to the main member, pivotably attached to the main member (330).

Floor care devices (102) having an elongated handle (160) or body portion for control thereof are provided with mid-level handles (170) for facilitating manipulation of the devices (102) in certain conditions, for storing power cords (162), for hanging and storing the floor care device (160) and the like. The mid-level handle (170) may fold from a retracted position adjacent the elongated handle (160) or body portion to an extended position. A retainer (182, 184) is provided to maintain the handle (170) in its retracted and extended positions.

An outer bag assembly (20) for an upright vacuum cleaner is disclosed. The outer bag assembly (20) comprises a flexible, air permeable enclosure having an internal volume adapted to contain a disposable inner bag. The outer bag assembly (20) is further comprised of an upper end adapted to provide access to the internal volume through a closure device, and an opposite end attached to a handle assembly (112) through a bag clip assembly (26). In one embodiment, the closure device includes a zipper (32) disposed along an upper front peripheral edge (34) of the outer bag assembly (20) that allows a front panel (22) of the bag assembly (20) to be partially released. In another embodiment, the closure device includes a zipper (52) disposed along an upper front peripheral edge (34), and a zipper (54) disposed along an upper rear peripheral edge of the outer bag assembly (20) that allows a top panel (58) of the outer bag assembly (20) to be partially released.

An apparatus (10) includes a body (14), a head (16), a handle (12), an audio source and audio output, and at least one control (43, 45, 46) on the handle for controlling the audio source. The floor care apparatus (10) may be a vacuum cleaner, carpet sweeper, extractor, or floor machine. The audio source may be a radio receiver, compact disk player, cassette tape player, or disk drive. The audio output may be a speaker or an electrical connector such as an audio or headphone jack (50). The audio control may be an on/off switch (42), a volume control, a tuning control, or a fast forward or rewind control. The floor care apparatus may further include a rechargeable power source. The handle (12) is configured to be gripped. The handle (12) may include a coupler sized and dimensioned to couple the handle to a desired apparatus (10), such as a floor care apparatus. The handle (12) may further include an electrical connector configured to couple with a complementary electrical connector in the apparatus to provide power and control therebetween. Visual indications (71, 73, 75, 77, 79, 81, 83) of the operating condition of the device and other alerts can be provided by readouts carried by the handle.
摘要:
An access panel mounted atop a vacuum nozzle base via finger operated latches. When the latches are undone the access panel is removed from the top surface of the nozzle base allowing access to the parts of the brush assembly. The panel also has an integral arm which engages a safety motor switch such that when the panel is removed the motor switch is switched into an open circuit position preventing the motor from continued operation.
