Description
VACUUM DEVICES HAVING INTEGRATED CORD STORAGE AND
PIVOTABLE TOOL HOLDERS
TECHNICAL FIELD
The present invention relates to cleaning devices, and more particularly, to vacuum devices having integrated cord storage and movable tool holders.
BACKGROUND OF THE INVENTION
Many contemporary cleaning devices are electrically powered. Such cleaning devices include vacuums, buffers, extractors, steam cleaners, and other devices. The electrical power is typically supplied to the cleaning device through a power cord. When not in use, the power cord may be removed from the cleaning device, or may be wrapped about a portion of the cleaning device for transport and storage.
Figure 1 is an isometric view of a vacuum device 10 in accordance with the prior art. As is well known, the vacuum device 10 includes a housing 12 having an intake port 14 coupled to a hose 16, and an exhaust port 18. A vacuum unit 20 (not shown) is disposed within the housing 12. A power cord 22 is attached to the housing 92 for providing electrical power to the vacuum unit 20. The housing includes a handle 24 for carrying the vacuum device 10. A control switch 26 is disposed in the handle 24 for controlling the power supplied to the vacuum unit 20.
A pair of cord hooks 28 project outwardly from a lateral side of the housing 12 for wrapping the power cord 22 when not in use.
In use, an operator grips the handle 24 and actuates the control switch 26 to transmit power supplied by the power cord 22 to the vacuum unit 20. As will be understood by persons of ordinary skill in the art, the vacuum unit 20 creates suction within the hose 16, drawing a particulate-laden airstream into the housing 12 through the intake port 14. The particulate-laden airstream may then pass through a removable filter element (e.g. a disposable paper bag) where particulates may be filtered from the particulate-laden airstream and captured for later disposal. The vacuum unit 20 then exhausts a filtered airstream out of the housing 12 through the exhaust port 18. After using the vacuum device 10, the t ' operator may prepare the device for storage or transport by successively winding S the power cord 22 about the cord hooks 28, placing the -power cord 22 in a ' stowed position (Figure 1).
The vacuum device 10 may also include a tool holder 30 attached to the housing 12. The tool holder 30 includes retaining projections 34 that may be engaged with one or more vacuum tools 32 (e.g. nozzles, brushes, etc.) to engage and retain the vacuum tools 32 until they are needed. The vacuum tools 32 may be attached to an attachment end 17 of the hose 16 for different cleaning applications.
Although highly beneficial results have been achieved, some aspects of the vacuum device 10 may be improved. In the embodiment shown in Figure 1, the vacuum device 10 is a hand-held device that may be used in a variety of applications. As such, it may be desirable to further optimize the portability and versatility of the vacuum device 10.

DETAILED DESCRIPTION OF THE INVENTION
The present invention is generally directed to vacuum devices having integrated cord storage and pivotable tool holders. Many specific details of certain embodiments of the invention are set forth in the following description and in Figures 2-6 to provide a thorough understanding of such embodiments.
One skilled in the art will understand, however, that the present invention may have additional embodiments, or that the present invention may be practiced without several of the details described in the following description.
Figures 2 and 3 are isometric and isometric exploded views, respectively, of a vacuum machine 100 in accordance with an embodiment of the invention.
Figures 4 and 5 are side elevationai and bottom plan views, respectively, of the vacuum machine 100 of Figure 2. As best shown in Figures 2 and 4, the vacuum device 100 includes a housing 112 having a bottom surface 150 with a recess disposed therein. As more fully described below, the recess 152 is sized to receive and store a plurality of loops of a power cord 122.
Referring to Figures 2 and 3, the housing 112 includes an intake port 114 coupled to a hose 116, and an exhaust port 118 ( shown as 118A and 1188 in Figure 3). An exhaust grill 119 is disposed over the exhaust port 118. A
vacuum unit 120 having an electric motor 121 (Figure 3) is disposed within the housing 112.
A control switch 126 is disposed in a handle 124 on the housing 112 for controlling the power supplied to the vacuum unit 120. A filter element 123 (e.g. a disposable vacuum bag) is positioned within the housing 112 to receive a particulate-laden airstream through intake port 114.
As best shown in Figures 4 and 5, a power cord 122 is attached to a cord mount 125 disposed on the bottom surface 150 of the housing 112. In this embodiment, the cord mount 125 is disposed within the recess i52, and is connected to the power cord 122 such that a localized portion of the power cord 122 proximate the cord mount 125 is inclined outwardly with respect to the bottom surface 150 (Figure 4). Alternately, the power cord 122 may be attached to the cord mount 125 such that the localized portion 121 is approximately parallel to the bottom surface 150 of the housing 112, or a base surface 153 (Figure 4) of the recess 152, or both. The power cord 122 is attached to the cord mount 125 such that the localized portion 121 projects approximately toward the forward the forward cord retainer 128A.
The housing 112 further includes forward and rearward cord retainers (or "hooks' 128A, 128B that project outwardly from the base surface 153 of the recess 152. Supports (or "feet's 154 project downwardly from the bottom surface 150 proximate the recess 152 to support the vacuum device I00 on a floor or other surface. In this embodiment, the cord retainers 128A, I28B
project outwardly to a distance approximately equal to the depth of the recess 152 (see Figure 4). Alternately, the cord retainers 128A, 128B may project outwardly by greater or lesser amounts. Preferably, the cord retainers I28A, 128B do not project beyond the supports 154.
To operate the vacuum device 100, an operator may grip the handle 124 and actuate the control switch 126 to transmit power supplied by the power cord 122 to the vacuum unit 120. The vacuum unit 120 creates suction within the hose 116, drawing a particulate-laden airstream into the housing 112 through the intake port 114. The particulate-Laden airstream then passes into the filter . element 123 where particulates are filtered and captured for later disposal.
The vacuum unit 120 then exhausts a filtered airstream out of the housing 112 through the exhaust port 118 and the exhaust grill 119 (Figure 3).
To prepare the vacuum device 100 for storage or transport, the operator may wind successive loops of the power cord 122 about the cord retainers 128A, 128B. First, the power cord 122 is pulled tightly from the cord mount 125 to the forward cord retainer 128A. The power cord 122 is then partially wrapped around the forward cord retainer 128A and back to the rearward cord retainer I28B. The power cord .122 is then partially wrapped around the rearward cord retainer 128B, and the process is repeated until a plurality of loops of the power cord 122 are successively wrapped about the cord retainers 128A, 128B, placing the power cord 122 is a stowed position 156 (Figure 5).
The vacuum device 100 advantageously provides improved . . stability characteristics over prior art vacuum devices. Because the power cord 122 is disposed within the recess 152 on the bottom surface 150, and because the power cord 122 may have significant mass as compared to the vacuum device 100 as a whole, the center of gravity of the vacuum device 100 is lowered, and the weight of the power cord 122 is more evenly distributed on the supports 154, .
' compared with prior art devices. The vacuum device 100 is therefore less likely to tip over and scratch or mar the housing 112 or other _components of the vacuum device 100. ~ -Another advantage is that when the power cord 122 is placed in the stowed position I56, the power cord 122 is.subjected to less bending stresses.
For example, when the operator begins, wrapping the power cord 122 about the cord retainers 128A, 1288, the power cord 122 is pulled between the cord mount 125 and the forward cord retainer 128A. This action subjects the localized portion I21 of the power cord 122 to primarily axial, tension forces rather than lateral bending forces. Because the power cord 122 is attached to the cord mount 125 such that the localized portion 121 projects approximately toward the forward cord retainer 128A, the forces generated within the localized portion l21 of the power cord 122 by the operator during wrapping of the cord are predominantly axial forces. The bending stresses that may fatigue and ultimately damage the power cord 122 within the localized portion 121 are thereby reduced or eliminated.
Refen-ing again to Figures 2 and 3, the vacuum device 100 may also include a pivotable tool holder 300. The tool holder 304 includes a base 3 i 0 having first and second arms 312 that pivotably engage into a pair of pivot holes 313 disposed in opposing lateral surfaces of the handle 124 (Figure 3). A
plurality of retaining members 320 project from the base 310 that are engageable with one or. more vacuum tools 32 (Figure 3). As shown in Figure 4, the tool holder 300 is pivotable between a first position 340 and a second position 342.
In this embodiment, with the vacuum device 100 resting on the supports 154, the base 310 is in an approximately horizontal position when the tool holder 300 is in the first position 340, and in an approximately vertical position when the tool holder 300 is in the second position 342.
Although the base 310 is shown as being pivotably connected to the handle 124 by a pair of arms 312, a variety of alternate embodiments are possible. For example, the arms 312 may be eliminated, and the base 310 may be ' attached to the handle 124 by a hinge. Alternately, as shown in Figure 6, the base 310 may be pivotably attached along a back edge 315_ of an upper surface 316 of the housing 112 by a hinge 317. In further embodiW ents, the tool holder 300 may be pivotably attached at other locations on the housing 112, may have a greater or fewer number of tool retaining members 320, and may be pivotably through a larger or smaller range of motion than that shown in Figure 4.
The tool holder 300 may be attached to the housing 112 using a variety of known attachment mechanisms that prevent the tool holder 300 from rotating freely between the first and second positions 340, 342, but that allow the tool holder 300 to be rotated between the first and second positions 347, 342 as desired by the operator, such as, for example, by the application of sufficient force, or by the actuation of a release mechanism, or by other similar action.
For example, a ball detent could be used as a restraining mechanism to maintain the tool holder 300 in the first and second positions 340, 342 (or in any intermediate position therebetween) until rotated out of such positions by the application of a sufficient pivoting force. Other laiown means may be used for maintaining the tool holder 300 in the desired positions.
The pivotable tool holder 300 may advantageously increase the versatility of the vacuum device I00. For example, in operation, when the vacuum device 100 is positioned on the supports 154 (Figure 4), the tool holder 300 may be positioned in the first position 340, providing easy access to the vacuum tools 32 engaged on the retaining members 320. For storing the vacuum device 100, the operator may pivot the tool holder 300 into the second position 342, allowing the exhaust grill 119 to be positioned proximate a wall or other surface and improving the storability of the vacuum device 100 within, for example, a closet, box, or other storage compartment. Alternately, if the operator desires to rest the vacuum device 100 on the exhaust grill 119, such as for g removal or installation of the filter element 123 (Figure 3), the tool holder may be pivoted into the second position 342 where it will not be damaged and where it will not interfere with the engagement of the exhaust grill I I9 on the ' support surface. Thus, the versatility and ease of operation of the vacuum device 300 may be improved _ Although the above-described embodiments have been shown and described in terms of an exemplary hand-held vacuum device, it will be understood that the teachings of the foregoing invention disclosure are applicable to a wide variety of cleaning devices. Therefore, the teachings of the foregoing disclosure will be understood to be applicable to a variety of floor care devices, including, .for example, upright and canister vacuums, buffers, extractors, steam cleaners, sweepers, carpet shampooers and other similar devices.
The detailed descriptions of the above embodiments are not exhaustive descriptions of all embodiments contemplated by the inventors to be within the scope of the invention. Indeed, persons skilled in the art will recognize that certain elements of the above-described embodiments may variously be combined or eliminated to create further embodiments, and such further embodirnents_fall within the scope and teachings of the invention. It will also be apparent to those of ordinary skill in the art that the above-described embodiments may be combined in whole or in part to create additional . embodiments within the scope and teachings of the invention.
Thus, although specific embodiments o~ and examples for, the invention are descn'bed herein for illustrative purposes, v~-ious equivalent modifications are possible within the scope of the invention, as those skilled in , the relevant art will recognize. The teachings provided herein can be applied to other vacuum devices having integrated cord storage and pivotable tool holders, and not just to the embodiments described above and shown in the accompanying figures. Accordingly, the scope of the invention should be determined from the following claims.

The tool holder 300 may be attached to the housing 112 using a variety of known attachment mechanisms that prevent the tool holder 300 from rotating freely between the first and second positions 340, 342, but that allow the tool holder 300 to be rotated between the first and second positions 347, 342 as desired by the operator, such as, for example, by the application of sufficient force, or by the actuation of a release mechanism, or by other similar action.
For example, a ball detent could be used as a restraining mechanism to maintain the tool holder 300 in the first and second positions 340, 342 (or in any intermediate position therebetween) until rotated out of such positions by the application of a sufficient pivoting force. Other laiown means may be used for maintaining the tool holder 300 in the desired positions.
The pivotable tool holder 300 may advantageously increase the versatility of the vacuum device I00. For example, in operation, when the vacuum device 100 is positioned on the supports 154 (Figure 4), the tool holder 300 may be positioned in the first position 340, providing easy access to the vacuum tools 32 engaged on the retaining members 320. For storing the vacuum device 100, the operator may pivot the tool holder 300 into the second position 342, allowing the exhaust grill 119 to be positioned proximate a wall or other surface and improving the storability of the vacuum device 100 within, for example, a closet, box, or other storage compartment. Alternately, if the operator desires to rest the vacuum device 100 on the exhaust grill 119, such as for g removal or installation of the filter element 123 (Figure 3), the tool holder may be pivoted into the second position 342 where it will not be damaged and where it will not interfere with the engagement of the exhaust grill I I9 on the ' support surface. Thus, the versatility and ease of operation of the vacuum device 300 may be improved _ Although the above-described embodiments have been shown and described in terms of an exemplary hand-held vacuum device, it will be understood that the teachings of the foregoing invention disclosure are applicable to a wide variety of cleaning devices.
