UPRIGHT VACUUM CLEANER NOZZLE HANDLE
An upright vacuum cleaner generally includes an upright assembly including a suction generator and a floor nozzle coupled to the upright assembly. The floor nozzle is configured for movement over a floor surface and includes a nozzle inlet in fluid communication with the suction generator. An aperture is formed through the floor nozzle and configured to allow the insertion of a hand of an operator to provide a gripping area on the floor nozzle adjacent the aperture to facilitate lifting and lowering the upright vacuum cleaner.
This application claims priority to U.S. Provisional Patent Application No. 61/757,875, filed Jan. 29, 2013, the entire contents of which are incorporated by reference herein.
BACKGROUNDVacuum cleaners typically include a suction nozzle, a cleaner housing connected to the suction nozzle, a suction generator in the cleaner housing, and a dirt collection vessel in the cleaner housing. In an upright-type vacuum cleaner, an elongate handle is coupled to the cleaner housing. The handle extends generally upwardly from the cleaner housing and transfers forces caused by the operator to the vacuum cleaner to move the vacuum cleaner over a surface to be cleaned.
SUMMARYIn one embodiment, an upright vacuum cleaner generally includes an upright assembly including a suction generator and a floor nozzle coupled to the upright assembly. The floor nozzle is configured for movement over a floor surface and includes a nozzle inlet in fluid communication with the suction generator. An aperture is formed through the floor nozzle and configured to allow the insertion of a hand of an operator to provide a gripping area on the floor nozzle adjacent the aperture to facilitate lifting and lowering the upright vacuum cleaner.
In another embodiment, an upright vacuum cleaner generally includes an upright assembly including a suction generator and a floor nozzle coupled to the upright assembly. The floor nozzle is configured for movement over a floor surface and includes a nozzle inlet disposed at a forward end of the floor nozzle and in fluid communication with the suction generator. An aperture is formed through the floor nozzle and disposed behind the nozzle inlet and entirely surrounded by walls of the floor nozzle. When viewed from above the floor nozzle, the aperture defines an area of approximately 20 cm2 or more.
Other aspects of the invention will become apparent by consideration of the detailed description and accompanying drawings.
It should be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the above-described drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting.
DETAILED DESCRIPTIONThe illustrated upright vacuum cleaner 100 is a dry vacuum cleaner capable of drawing in air and dirt such as dry debris. In alternative embodiments, the upright vacuum cleaner 100 may be a wet vacuum cleaner capable of drawing in air and dirt such as liquid and debris. Alternatively, the upright vacuum cleaner 100 may be an extractor capable of both dispensing liquid and drawing in air and dirt such as liquid and debris. In still other embodiments, the upright vacuum cleaner 100 may be a stick vacuum that does not include the brush rolls of other traditional upright cleaners.

An aperture or opening 170 is formed through the floor nozzle 130. In the illustrated embodiment, the aperture 170 is entirely surrounded by walls 180 of the floor nozzle 130. In other embodiments, however, the aperture 170 may be merely partially surrounded by the walls 180 of the floor nozzle 130 and partially left open. As illustrated in
In the illustrated embodiment, the aperture 170 is disposed behind or rearward to (i.e., to the right in
In some embodiments, the aperture 170 is disposed behind the brush roll housing 150 spaced approximately 4 cm to approximately 15 cm from the forward end of the floor nozzle 130. In other embodiments, the spacing between the aperture 170 and the forward end of the floor nozzle 130 may assume other values. In still other embodiments, for example in a stick vacuum, the aperture 170 may be disposed behind the nozzle inlet 140 without regard to the brush roll housing 150. In some embodiments, the floor nozzle 130 defines a lateral dimension Lf ranging from approximately 25 cm to approximately 35 cm and the aperture 170 is positioned approximately at a center of the lateral dimension Lf. In other embodiments, the lateral dimension Lf may assume other values, and the aperture 170 may be positioned approximately at the respective center of the lateral dimension Lf. In still other embodiments, the aperture 170 may be positioned off-center relative to the lateral dimension Lf. In some embodiments, the aperture 170 when viewed from above the floor nozzle 130 defines an area of approximately 20 cm2 or more. In further embodiments, the aperture 170 when viewed from above the floor nozzle 130 defines an area of approximately 20 cm2 to approximately 80 cm2. In still further embodiments, the aperture 170 defines a lateral dimension La ranging from approximately 5 cm to approximately 10 cm. In other embodiments, the aperture may be dimensioned to suitably facilitate lifting and lowering the upright vacuum cleaner, as explained below.
