  • Patent number: 8108967
    Abstract: A handle assembly for a cleaning appliance includes a slidably extendible wand and a connecting portion that includes a first locking arrangement releasably securing the handle assembly to the main body of the cleaning appliance, a second locking arrangement releasably locking the wand in a pre-determined position with respect to the connecting portion and an actuator. The actuator is adapted and arranged to move the first and second locking arrangements between locked and unlocked positions. The first locking arrangement is movable independently of the actuator. This arrangement allows a single actuator to be operated by a user to unlock both the first and second locking arrangements simultaneously. However, because the first locking arrangement can move independently of the second locking arrangement, it is possible to secure the handle assembly to the main body of the cleaning appliance while keeping the wand in a locked position.

  • Patent number: 7996956
    Abstract: A cleaning appliance includes a main body and a collecting chamber releasably held on the main body. The collecting chamber includes a closure member which is movable between a closed position and an open position in which the collecting chamber can be emptied and an actuating member adapted and arranged to release the collecting chamber from the main body and, when the collecting chamber is released from the main body, to release the closure member from the closed position. By providing such an arrangement, a single actuating member can be used to release the collecting chamber from the main body of the cleaning appliance and also to open the closure member to empty the collecting chamber. A single actuating member is less complex, requires less space and is more intuitive for a user to operate.
