20100017997 | Vacuum Cleaner - The invention relates to a vacuum cleaner of a type comprising an elongated support body ( | 01-28-2010 |
20100024154 | Vacuum Cleaner With Filter Cleaning Means - A hand held vacuum cleaner comprises a housing ( | 02-04-2010 |
20100083459 | Air Flow Losses in Vacuum Cleaners - A vacuum cleaner having an elongated support body, a nozzle attached to a lower end of the elongated support body by an articulated joint, a motor, a fan unit, a debris container, and an air passage that extends from the nozzle device, past the articulated joint by a flexible hose and to an air passage in the support body. The flexible hose is formed with a generally rectangular cross section. | 04-08-2010 |
20100083460 | Vacuum Cleaner Nozzle and Roller - The invention relates to a vacuum cleaner nozzle of the kind being adapted to be moved over a floor ( | 04-08-2010 |
20100242209 | Handheld Vacuum Unit Retention Features - A vacuum cleaner having a base with an inlet facing a surface, a handle connected to the base, an air passage connecting the base inlet to the handle, and a removable handheld unit. The handheld has an inlet nozzle, a dirt separator, a vacuum fan to generate a working airflow into the inlet nozzle and through the dirt separator, and a housing joining the handheld, the dirt separator and the vacuum fan. The vacuum has a docking latch with a first latch position in which the latch holds the handheld in an operating position on the handle, and a second position in which the latch permits removal of the handheld from the operating position. The vacuum also has a safety catch with a catch member on the handle and a second member on the handheld. The catch members resiliently hold the handheld unit on the handle in a partially-removed position. | 09-30-2010 |
20100293743 | Vacuum Cleaner with Filter Cleaning - A vacuum cleaner with a vacuum, a filtering unit, switching means for switching between a vacuum cleaning and filter cleaning modes, and a separating unit. In the vacuum cleaning mode, the vacuum forces a first air stream in a first air stream path through the filtering unit, in a first direction, to filter out dust from the dust laden air stream. In the filter cleaning mode, the vacuum forces a second air stream in a second air stream path through the filtering unit, in a second direction reverse to the first direction, to remove dust from the filtering unit. In the filter cleaning mode, the separating unit is in the air path between the vacuum and the filtering unit to separate dust removed from the filtering unit. In the vacuum cleaning mode, the separating unit is not in an air stream path. | 11-25-2010 |
20100299867 | Vacuum Cleaner Agitator Clutch - A vacuum cleaner clutch assembly having an input driven by a motor, an output to drive an agitator, a starter clutch and a drive clutch. The starter clutch moves between an engaged position in which it receives a first drive torque from the input, and a disengaged position in which it receives substantially no torque directly from the input. The drive clutch is moveable between an engaged position in which it receives a second drive torque from the input, and a disengaged position in which it receives substantially no torque directly from the input. When engaged, the starter clutch is coupled to the drive clutch to transmit the first drive torque to the drive clutch to move the drive clutch into the engaged drive clutch position. When engaged, the drive clutch is coupled to the clutch assembly output to transmit the second drive torque to the output. | 12-02-2010 |
20100299868 | Vacuum Cleaner Overload Clutch - A vacuum cleaner overload clutch having an overload cog, a spring mount, and an overload spring. The spring is engaged with the cog to provide torque transfer, and disengaged from the cog to terminate torque transfer. The spring may not reengage until the parts stop rotating. A weight may be provided to bias the spring into the disengaged position, and the spring may have an engagement portion that is captured between the overload cog and a wall on the spring holder when the clutch is engaged. The clutch may be part of a system including a motor and agitator, and may have other features, such as a graduated engagement clutch. | 12-02-2010 |
20120080057 | Vacuum Cleaner - A vacuum cleaner having a main separating unit, a filter, an auxiliary separating unit, a vacuum source adapted to generate an airstream, and airflow passages configured to operate in a vacuum cleaning mode and a filter cleaning mode. In the vacuum cleaning mode, the airflow passages are configured to direct the airstream through the main separating unit and then through the filter in a first direction, and the airflow substantially bypasses the auxiliary separating unit. In the filter cleaning mode, the airflow passages are configured to direct the airstream through the filter in a second direction, opposite the first direction, and then through the auxiliary separating unit. A method for operating a vacuum cleaner is also provided. | 04-05-2012 |
20130186725 | VACUUM CLEANER AGITATOR CLUTCH - A vacuum cleaner brushroll clutch having a motor, clutch assembly input rotated by the motor, brushroll, clutch assembly output to rotate the brushroll, drive clutch, and starter clutch. The drive clutch is connected to the clutch assembly output and moveable between a first position in which it does not directly contact the clutch assembly input and a second position in which it directly contacts the clutch assembly input to transmit a first torque directly from the clutch assembly input to the clutch assembly output. The starter clutch is connected to the drive clutch and moveable between a first position in which it does not engage the clutch assembly input and a second position in which it engages the clutch assembly input to transmit a second torque from the clutch assembly input to the drive clutch to move the drive clutch into the second drive clutch position. | 07-25-2013 |
