Description
- This patent application claims priority to U.S. provisional patent application No. 60/799,201, filed May 9, 2006, the disclosure of which is incorporated herein in its entirety by reference.
- A surface treatment apparatus for accessing and treating surfaces includes a lockable universal positioning joint to permit the apparatus to be articulated and configured in an ergonomically safe and comfortable user form factor.
- Accessing and contacting surfaces that are typically difficult or impossible to reach with a human arm, or with the assistance of tools or implements that help to extend the length of a user's arm, often require the user to be located in an uncomfortable and unsafe position. Prior art tools and implements exist that help to extend the length of a human arm for purposes of accessing and contacting a surface, such as, for cleaning, treating, sealing, polishing, painting, texturizing, sanding, and otherwise affecting the surface. Such tools and implements however often position an end user in an uncomfortable position such that the user experiences body and arm strain in an effort to appropriately use a tool. In addition, a user's efforts to employ a particular tool or implement may place the user in an unsafe or dangerous position. Further, a tool or implement may not be appropriately and effectively employed, and therefore does not achieve its full potential, because of a user's inability to safely and comfortably use the tool or implement. In the context of window cleaning, this is apparent whereby prior art tools or implements often require a user to be in an uncomfortable and/or unsafe position when attempting to access and contact difficult to reach areas of window surfaces, such as, for example, exterior window surfaces and window surfaces of relatively tall and wide windows.
- An object of the invention includes an improved surface treatment apparatus and, more particularly, an improved window cleaning apparatus, which defines an ergonomic form factor that permits a user of the apparatus to effectively, safely and comfortably employ the apparatus to access and contact surfaces for treatment and/or cleaning.

As shown inFIGS. 2 and 3 , the cleaninghead 12 is positioned in a substantially perpendicular orientation relative to theextendible wand 18 and above a user's hand and arm to enable access to exterior surfaces of a window, while the user remains in a safe and comfortable position inside the window casement. In addition, the geometry of the cleaninghead 12 relative to theextendible wand 18 and a user's hand and arm helps to permit the user to safely and comfortably move the cleaninghead 12 along the exterior window surface. As shown inFIGS. 2 and 3 , a user performs a vertical cleaning motion or stroke from inside the window casement. - As described below, the
swivel arm 14 further disposes the cleaninghead 12 by pivoting, as shown by arrow 100 inFIG. 1 , to position or angle the cleaninghead 12 toward a window surface to help to facilitate effective contact of the cleaninghead 12 with the window surface. - In addition, as shown in
FIG. 3 and as will be described below, theapparatus 10 defines a low or narrow profile to permit theapparatus 10 to extend between two panes of, for instance, a double hung window to enable window surface cleaning. As described above, the geometry of the cleaninghead 12 relative to theextendible wand 18 and a user's arm and hand help to facilitate access to difficult to reach window surfaces, such as those shown, and to enable the user to safely and comfortably clean such surfaces. - Referring to
FIGS. 4-5 , and with further reference toFIG. 1 , theswivel arm 14 and/or the universal joint 12 also position the cleaninghead 12 in a substantially horizontal orientation relative to theextendible wand 18 and a user's hand whereby the cleaninghead 12 is horizontally parallel to thewand 18 and a user's hand. In addition, the cleaninghead 12 may be further aligned with thewand 18 and a user's hand to dispose thehead 12 at approximately the same height as thewand 18 and the user's hand. This configuration of theapparatus 10 is useful for cleaning exterior surfaces of windows that are relatively wide and would typically require a user to reach far outside a window casement, with difficulty, danger and discomfort to the user, to enable the user to reach all areas of an exterior window surface. As mentioned, the length L1 of theextendible wand 18 configures theapparatus 10 with sufficient length to enable a user to reach all areas of an exterior surface of a wide window with the cleaninghead 12 without the user dangerously extending their arm or body far outside the window and experiencing body and arm strain. Theswivel arm 14 and/or the universal joint 16 dispose the cleaninghead 12 at an optimal geometry relative to thewand 18 and a user's hand to help to achieve effective contact of the cleaninghead 12 with a window surface and to enable the user to safely and comfortably move the cleaninghead 12 along the window surface in an upward/downward vertical motion or stroke. - In addition, configuration or orientation of the
apparatus 10, as shown inFIGS. 2-5 , may be adjusted, e.g., turned about 45 degrees, such that a user can employ theapparatus 10 to accomplish a safe and comfortable back and forth horizontal motion or stroke across a window surface. Further, the cleaninghead 12 and theextendible wand 18 may define any other geometry than those shown inFIGS. 2-5 to position or orient the cleaninghead 12 relative to a user's hand and/or arm and to optimize a form factor theapparatus 10 defines relative to a particular type and size of window. - Referring to
FIG. 6 , and with further reference toFIG. 1 , the cleaninghead 12 is a low profile member including at least one cleaning implement, such as, for instance, awiper blade 12A, as shown inFIGS. 1 and 6 . Preferably, the cleaninghead 12 is an elongated member and the at least one cleaning implement covers at least a portion of the length of the member to provide theapparatus 10 with sufficient and effective surface cleaning area. The length of the cleaninghead 12 and the cleaning implement may be any of a range of lengths, depending upon the window cleaning application. - The cleaning
head 12 may be one-sided, wherein the cleaninghead 12 includes a single implement, such as the wiper blade 10A, disposed along a first side of the cleaninghead 12. Optionally, the cleaninghead 12 may be two-sided, wherein a second implement, such as, for instance, a scrubber rail orsponge 12B, may be disposed along a second side of the cleaninghead 12, e.g., opposite to the first side, as shown inFIGS. 1 and 6 , to incorporate the cleaninghead 12 with multiple functions. In addition, the implement and, in particular, the wiper blade 10A and the scrubber rail orsponge 12B may be removably secured to the cleaninghead 12 such that the wiper blade 10A and the rail or sponge 10B can be removed for cleaning, storage, or repair or for replacement with other cleaning implements. The invention is not limited to the type of implement disposed along the cleaninghead 12 and envisions the cleaninghead 12 is configured to accept any of variety of other implements including, but not limited to, a scraper, a brush, a roller, a drier, an applicator, and any other implement configured to clean, treat and/or otherwise contact a window surface for a particular application. - The
wiper 12A and the scrubber rail orsponge 12B are disposed and angled along at least a portion of the length of the cleaninghead 12 and are configured to contact a surface, e.g., substantially the entire length of thewiper 12A or the scrubber rail orsponge 12B contacts a surface, to be cleaned. - The interior of the cleaning
head 12 defines an internalfluid channel 12C configured to receive fluid from a fluid channel the interior of theswivel arm 14 defines, as described below. The internalfluid channel 12C extends along at least a portion of the interior of the cleaninghead 12 to distribute fluid through the member. The cleaninghead 12 further includes one or more spray jets ornozzles 12D disposed along the cleaninghead 12 and configured in fluid communication with the internalfluid channel 12C. Each spray jet ornozzle 12D includes anoutlet 12E configured in fluid communication with the internalfluid channel 12C to receive fluid from thechannel 12C to enable the jet ornozzle 12D to express fluid from the cleaninghead 12. The jets ornozzles 12D may be positioned substantially equidistant from one another along the cleaninghead 12. Optionally, one or more of the jets ornozzles 12D are adjustable such that the positions of theoutlets 12E are altered to change the direction in which the jets ornozzles 12D express fluid. - As shown in
FIGS. 1 and 6 , the jets ornozzles 12D are disposed along the second side of the cleaninghead 12 preferably above the scrubber rail orsponge 12B, or other implement(s), to express fluid from the cleaninghead 12 above the rail orsponge 12B to a surface to be cleaned. For instance, when the rail orsponge 12B contacts a surface to be cleaned, one or more jets ornozzles 12D express fluid above the rail orsponge 12B to help to prevent running or streaking of fluid along the surface below the rail orsponge 12B to thereby facilitate efficient application of fluid and surface cleaning. Alternatively, or additionally, the jets ornozzles 12D may be disposed along the first side of the cleaninghead 12 above thewiper blade 12A, or other implement(s). -
FIG. 6 illustrates a cross-sectional view of the low profile of the cleaninghead 12 that results from the compact dimensions of the cleaninghead 12 and the low profile of thewiper blade 12A, the scrubber rail orsponge 12B, and/or the plurality of jets ornozzles 12D. As shown, the cleaninghead 12 may define a width W1 that is relatively narrow, e.g., approximately one inch or two inches. In addition, the width W1 of the cleaninghead 12 may be related to the application, e.g., the type of windows or other surfaces, in which theapparatus 10 is being used. As an example,FIG. 6 shows the cleaninghead 12 positioned between theseparate panes head 12 that permits theapparatus 10 and, in particular, the cleaninghead 12 to access the interior surfaces of thepanes - With further reference to
FIG. 1 , thelockable swivel arm 14 is connected to aterminal end 12F of the cleaninghead 12 and is configured to swivel or pivot, as shown by arrow 100 inFIG. 1 , about a lockable swivel joint 14A to permit adjustment of a position or an angle of the cleaninghead 12. Theswivel arm 14 includes afirst portion 14B connected to the cleaning headterminal end 12F and slidably received by asecond portion 14C that is connected to the lockableuniversal positioning joint 16. The swivel joint 14A is defined at about the point at which the first and thesecond portions second portions portions FIG. 1 , when disposed in an unlocked position. The swivel joint 14A may include any of a variety of locking mechanisms constructed and arranged to releasably lock the first andsecond portions swivel arm 14 and the cleaninghead 12 at a desired or required position or angle. Suitable locking mechanisms enable the swivel joint 14A to be configured as a fluid tight joint and may include, but are not limited to, screw clamps, cam locks, collet locks, ratchet locks, friction clamps, tooth locking mechanisms, cammed magnetic locks, magnetic cable locks and similar configurations. - When unlocked, the swivel joint 14A helps to facilitate position adjustment and angling of the cleaning
head 12 relative to a surface to be cleaned such that the cleaninghead 12 effectively contacts the surface for cleaning. In addition, theswivel arm 14 helps to further facilitate adjustment of a position and/or an angle of the cleaninghead 12 to help configure an optimal geometry of the cleaninghead 12 relative to theextendible wand 18 such that a user of theapparatus 10 achieves, as described above, an ergonomically comfortable and effective extension of theapparatus 10 and a cleaning motion or stroke of the cleaninghead 12. Further, theswivel arm 14 helps to angle or position the cleaninghead 12 to enable a user to manipulate theapparatus 10 and/or the cleaninghead 12 to move around obstacles in the path of the cleaninghead 12. The cleaninghead 12 permits a user to move around or next to, for instance, window frames, panes, and other obstacles with a comfortable and effective cleaning motion or stroke. - As shown in
FIGS. 1-5 , thefirst portion 14B of theswivel arm 14 defines a right angle to dispose the cleaninghead 12 at a distance from theextendible wand 18 sufficient to permit pivoting movement and angling adjustment of the cleaninghead 12 toward a window surface to facilitate effective contact of the cleaninghead 12 with the window surface. The angle of theswivel arm 14 also helps to dispose the universal locking joint 16 at a position opposite to the cleaninghead 12 that is in alignment with approximately the center of theelongated cleaning head 12, as shown inFIG. 1 . In this configuration, theapparatus 10 conveys pressure or force that a user applies to theapparatus 10 to the cleaninghead 12, such that, the pressure or force the cleaninghead 12 applies to a surface is substantially consistent along at least a portion of the length of the cleaninghead 12 in contact with the surface. The contact thecleaning head 12A makes with a surface and the pressure or force the cleaninghead 12 applies to the surface, e.g., during movement of the cleaninghead 12 along the surface, is substantially consistent along at least a portion of the length of the cleaninghead 12 in contact with the surface. For example, when a user applies pressure or force to theapparatus 10 configured as shown inFIG. 1 , thewiper blade 12A contacts and applies pressure or force to a surface substantially consistently along at least a portion of its length in contact with a surface. As a result, the motion or stroke of thewiper blade 12A along a surface is more consistent and effective. - The angle of the
swivel arm 14 further helps a user of theapparatus 10 to manipulate or work the cleaninghead 12, and, more particularly, any cleaning implement attached to the cleaninghead 12, into comers and narrow openings, around or adjacent obstacles in the cleaning head path, such as window panes and frames, and other difficult to access or clean areas of window surfaces. - Still referring to
FIG. 1 , and with further reference toFIGS. 2-5 , theapparatus 10 includes the lockable universal positioning joint 16 constructed and arranged to articulate theapparatus 10 whereby a position or an angle of the cleaninghead 12 relative to theswivel arm 14, theextendible wand 18 and/or thehandle 20 is achieved to adjustably position or orient the cleaninghead 12 and/or theextendible wand 18 at an appropriate and optimal geometry. As mentioned, theuniversal joint 16 configures theapparatus 10 in an ergonomically safe, comfortable and effective user form factor. Such form factor enables a user to access difficult to reach areas of window surfaces with theapparatus 10 and to produce an effective and comfortable cleaning motion or stroke along window surfaces with the cleaninghead 12 while the user remains in a safe and comfortable position inside window casements. The form factor also helps to eliminate the need for a user to extend their arm and/or body dangerously and/or uncomfortably outside a window casement. - As shown in
FIGS. 2-5 , the joint 16 permits theswivel arm 14 and/or theextendible wand 18 to pivot, in a direction shown byarrow 200 inFIG. 1 , about the joint 16 to position or orient the cleaninghead 12 in a variety of positions relative to theswivel arm 14, theextendible wand 18, and/or thehandle 20, as may be required or desired for a particular application. The geometry of the cleaninghead 12 relative to theextendible wand 18, theswivel arm 14 and/or thehandle 20 may permit a user's hand and arm to be disposed approximately below the cleaninghead 12 during use of theapparatus 10, or to be disposed parallel to and, optionally, inline with the cleaninghead 12 to configure theapparatus 10 in the required or desired form factor. - The universal positioning joint 16 includes a locking mechanism constructed and arranged to releasably and securely lock the
swivel arm 14 and theextendible wand 18 in a given position and is configured as a fluid tight joint. Suitable locking mechanisms include, but are not limited to, screw clamps, cam locks, collet locks, ratchet locks, friction claims and any locking configurations or combinations. - With further reference to
FIG. 1 , an interior of theswivel arm 14 defines an internal fluid supply channel (not shown) that is disposed in fluid communication with an internal fluid supply channel (not shown) that an interior of the positioning joint 16 defines. The internal fluid supply channels of thearm 14 and the joint 16 help to deliver fluid to theinternal channel 12C of the cleaninghead 12. - The internal fluid supply channel of the positioning joint 16 may include an enclosed, gasketed cavity internally disposed within the joint 16. Alternatively, the fluid supply channel of the joint 16 may be disposed along an outer surface of the joint 16, and configured at one end to connect to the internal fluid channel of the
extendible wand 18 and at another opposite end to the internal fluid channel of theswivel arm 14 via fluid-tight ports. In this case, the channel would extend from an output port of theextendible wand 18, along the external surface of the joint 16, and terminate into an input port defined in theswivel arm 14 to convey fluid from thewand 18 to theswivel arm 14. - As described below, an interior of the
extendible wand 18 defines an internal fluid supply channel in fluid communication with the channel of the joint 16 to deliver fluid expressed from aninterior reservoir 21 of thehandle 20 to the channels of the joint 16 and thearm 14 and ultimately to the internalfluid channel 12C of the cleaninghead 12. - As shown in
FIG. 1 , theextendible wand 18 is constructed and arranged to adjust the length and the geometry of theapparatus 10 relative to the application or surface, e.g., the type and size of a window, in which theapparatus 10 is used. Theextendible wand 18 includes afirst portion 18A that is telescopically and slidably received by asecond portion 18B. Thefirst portion 18A moves inward into the interior of thesecond portion 18B to reduce the length L1 of theextendible wand 18 and extends outwardly from the interior of thefirst portion 18A to increase the length L1 of the extendible wand, as shown byarrow 300 inFIG. 1 . - The
extendible wand 18 is further configured along oneend 18C of thesecond portion 18B to releasably lock the first and thesecond portions portions extendible wand 18 includes a locking mechanism to releasably lock the first and thesecond portions - As shown in
FIG. 1 , thehandle 20 is connected to asecond end 18D of theextendible wand 18 and includes within its interior afluid reservoir 21 configured to contain a fluid, e.g., a cleaning, coating, sealing, or drying fluid. Thehandle 20 further includes amanual air pump 22 disposed along a terminal end of the handle and in fluid communication with thereservoir 21 to deliver or pump air into thereservoir 21. Thepump 22 is slidably connected to thehandle 20 to permit thepump 22 to be actuated by moving the pump into and out of thehandle 20, as shown byarrow 400 inFIG. 1 . The action of thepump 22 introduces air into thereservoir 21 which pressurizes the interior of thereservoir 21 such that thereservoir 21 contains fluid under pressure. Thehandle 20 further includes anactuating trigger 23 that, when manual actuated, e.g., pulled, thetrigger 23 enables an amount of pressure to be released from thereservoir 21 and, as a consequence, an amount of fluid to be expressed from thereservoir 21 into the internal channel of theextendible wand 18. The invention is not limited in this respect and envisions other means of pressurizing and expressing fluid from thefluid reservoir 21 of thehandle 20, as described below. - Referring to
FIG. 7 , the length L2 of theapparatus 10 may be further adjusted, e.g., lengthened, with the attachment of one ormore extension elements 30 via aquick disconnect coupling 32 along one end of theelement 30 configured to removably connect to thesecond end 18D of theextendible wand 18, and a quick disconnect coupling 34 along another end of theelement 30 configured to removably connect to adistal end 20A of thehandle 20. Thequick connect couplings 32 and 34 are configured as fluid tight couplings. - Referring to
FIG. 8 , exemplary couplings are illustrated. Any of thedisconnect couplings 32 and 34 shown inFIG. 7 may be configured as coupling 40 or 50. In addition, thesecond end 18D of theextendible wand 18 and thedistal end 20A of thehandle 20 shown inFIG. 7 may be configured as coupling 45 or 55. Thecouplings couplings extension element 30 and theextendible wand 18 and thehandle 20. The invention is not so limited and anticipates that fluid tight joints or connections between theextension element 30, theextendible wand 18 and thehandle 20 can be configured and achieved with other designs including, but not limited to, elastomeric scrapers, spring and elastomer sealing and other similar configurations and devices. - The
coupling 40 further includes one or more snap locks orlock tabs 42 configured for quick release from complementary snap locks 46 configured along thecoupling 45. Thecoupling 50 further includesscrew threads 52 configured to mate withcomplementary screw threads 56 along thecoupling 55 to achieve a screw thread seal. The invention is not limited to these configurations and envisions the connection of theextension element 30 and theextendible wand 18 or thehandle 20 can be configured and achieved with liquid tight screw connections, quick release catches, quick release slide collars and other similar configurations and devices. - As shown in
FIGS. 8A and 8B , thecoupling conduit conduit complementary coupling extension element 30 to internally receive fluid from thereservoir 21 of thehandle 20 and to channel fluid to the internal channel of theextendible wand 18. - With further reference to

Thefluid pump 25 configuration is known and further details need not be disclosed here. Actuation of thetrigger 26, e.g., pullingtrigger 26, causes thefluid pump 25 to draw fluid from thefluid reservoir 27 into thefluid pipe 28 and to express fluid from thefluid pipe 28 through thepump 25 and into the internal fluid supply channel within the interior of theextendible wand 18, and, if connected, within the interior(s) of one ormore extension elements 30, to ultimately supply the internalfluid channel 12C of the cleaninghead 12 with fluid. Thefluid pump 25 is constructed and arranged to express fluid from thefluid pipe 28 with pressure sufficient to cause fluid to flow to the cleaninghead 12. - Referring to
FIGS. 9 and 10 , theapparatus 10 shown inFIGS. 1 and 7 may be removably connected to a remotefluid supply container 60. In the preferred embodiment, thecontainer 60 is portable and its interior defines aninternal reservoir 61 to contain a volume of fluid to supply or refill thehandle reservoir fluid tube 62.

In the preferred embodiment, thecontainer 60 defines a configuration, shape, and/or profile that permit thecontainer 60 to be comfortably disposed proximate to a user's body during use of theapparatus 10. As shown inFIGS. 9 and 10 , thecontainer 60 defines aconcave surface 67. Theconcave surface 67 is configured to help to promote portability of thecontainer 60 and to dispose thecontainer 60 in close proximity to a user of theapparatus 10 and/or to the user's body during use of theapparatus 10, such as, when thecontainer 60 is attached or clipped to, for instance, the user's belt to enable thecontainer 60 to be carried by a user with comfort and ease. - Referring
FIG. 11 , in a further aspect, the invention provides anapparatus 10 as shown in eitherFIG. 1 orFIG. 7 including analternative handle 70. Thehandle 70 is solid and includes anintegrated pressurizing pump 25, as shown inFIG. 7 , and anactuating trigger 72. Actuation of thepump 25 is achieved by manually actuating thetrigger 72, which draws fluid from thecontainer 60 through thefluid tube 62 and into the internal fluid supply channel of theextendible wand 18. In this embodiment, the fluid supply is maintained solely by thecontainer 60 in contrast to thehandle internal reservoir - Referring to
FIG. 12 , in another aspect, the invention provides anapparatus 80 including the components of theapparatus 10 described above and in reference toFIGS. 1-11 with an alternative fluid delivery system. Theapparatus 80 includes, as an alternative to the fluid channels or conduits defined by the interiors of theextendible wand 18 and the one ormore extension elements 30, an externalfluid supply tube 82 disposed external to thefluid reservoir 27. Thesupply tube 82 is connected at one end to an output port 84 defined in thehandle 24 and in fluid communication with thereservoir 27. Thesupply tube 82 is further connected at another end to an input port 84 defined in theswivel arm 14 and in fluid communication with the internal fluid supply channel defined by the interior of theswivel arm 14 and with the internalfluid channel 12C of the cleaninghead 12.
