Definitions
- Toilet bowls require care to prevent the buildup of unsightly deposits, to reduce odors, and to prevent bacteria growth.
- toilet bowls have been cleaned, deodorized, and disinfected by manual scrubbing with a liquid or powdered cleaning and sanitizing agent. This task has required manual labor to keep the toilet bowl clean.
- One type of dispenser comprises a solid block or solid particles of a cleansing and freshening substance that is suspended from the rim of a toilet bowl in a container that is placed in the path of the flushing water.
- U.S. Pat. No. 4,777,670 shows an example of this type of toilet bowl cleaning system.
- a portion of the solid block is dissolved in the flush water with each flush, and the flush water having dissolved product is dispensed into the toilet bowl for cleaning the bowl.
- WO 99/66139 and WO 99/66140 all disclose cleansing and/or freshening devices capable of being suspended from the rim of a toilet bowl for introducing liquid active substances from a bottle into the flushing water with each flush.
- the liquid active substances are delivered downward from a reservoir to a dispensing plate that is supported by a base that is suspended from the toilet bowl rim.
- the device is suspended from the toilet rim such that the flow of flush water from the toilet contacts the dispensing plate during a flush.
- the flush water carries the liquid active substances that are on the dispensing plate into the toilet bowl to clean and freshen the toilet.

Description
- This application is a continuation-in-part of U.S. Pat. application Ser. No. 11/312,281 filed Dec. 20, 2005.
- Not Applicable.
- 1. Field of the Invention
- This invention relates to a clip for mounting a fluid delivery device for spraying a fluid, such as a cleaner or deodorizer, on the inside surfaces of an enclosure, such as a toilet bowl, a shower enclosure, or a bathtub enclosure, where the body of the clip can be rotatably adjusted relative to the hook of the clip to direct dispensed fluid to the inside surfaces of the enclosure.
- 2. Description of the Related Art
- Toilet bowls require care to prevent the buildup of unsightly deposits, to reduce odors, and to prevent bacteria growth. Traditionally, toilet bowls have been cleaned, deodorized, and disinfected by manual scrubbing with a liquid or powdered cleaning and sanitizing agent. This task has required manual labor to keep the toilet bowl clean.
- In order to eliminate the detested manual scrubbing, various toilet bowl cleaner dispensers have been proposed. One type of dispenser comprises a solid block or solid particles of a cleansing and freshening substance that is suspended from the rim of a toilet bowl in a container that is placed in the path of the flushing water. U.S. Pat. No. 4,777,670 (which is incorporated herein by reference along with all other documents cited herein) shows an example of this type of toilet bowl cleaning system. Typically, a portion of the solid block is dissolved in the flush water with each flush, and the flush water having dissolved product is dispensed into the toilet bowl for cleaning the bowl.
- Other toilet bowl cleaning systems use a liquid cleaning agent that is dispensed into a toilet bowl. For example, U.S. Pat. Nos. 6,178,564 and 6,230,334, and PCT International Publication Nos. WO 99/66139 and WO 99/66140 all disclose cleansing and/or freshening devices capable of being suspended from the rim of a toilet bowl for introducing liquid active substances from a bottle into the flushing water with each flush. In these under the toilet rim devices, the liquid active substances are delivered downward from a reservoir to a dispensing plate that is supported by a base that is suspended from the toilet bowl rim. The device is suspended from the toilet rim such that the flow of flush water from the toilet contacts the dispensing plate during a flush. The flush water carries the liquid active substances that are on the dispensing plate into the toilet bowl to clean and freshen the toilet.
- Other toilet bowl dispensers use an aerosol deodorizing and/or cleaning agent that is dispensed into a toilet bowl through a conduit attached to the toilet bowl rim. For example, U.S. Pat. No. 3,178,070 discloses an aerosol container mounted by a bracket on a toilet rim with a tube extending over the rim; and U.S. Pat. Nos. 6,029,286 and 5,862,532 disclose dispensers for a toilet bowl including a pressurized reservoir of fluid, a conduit connected to the source of fluid, and a spray nozzle which is installed on the toilet rim.
- One disadvantage with these known toilet rim dispensing devices is that these devices may only apply the deodorizing and/or cleaning agent to one location in the toilet water or a limited area in the toilet water or on the inner surface of the toilet bowl. As a result, the cleaning of the inner surface of the toilet bowl may be limited to an area of the toilet bowl near the device.
- U.S. Pat. application Ser. No. 11/312,281, which is owned by the owner of the current invention, sets forth, among others, an automatic or manual toilet bowl cleaning device where the inner surface of the toilet bowl is cleaned around the entire circumference of the toilet bowl. In one embodiment illustrated in that application, the downstream end of the conduit terminates in a nozzle capable of spraying the fluid outwardly onto the inner surface of the toilet bowl. The nozzle is attached near the rim of the toilet bowl.
- Several techniques are available to provide limited adjustment for devices attached to the rim of a toilet bowl. Adjustment has been generally limited to either (1) accommodating toilet bowl rims of varying width, as shown in U.S. Pat. No. 6,029,286 wherein a ratchet arrangement between two members of the hook is used to adjust the hook for varying rim widths, or (2) attempting to accommodate the depth of the rim and bowl geometry by adjusting the vertical position of the device below the rim. For example, U.S. Pat. No. Re. 32,017 and U.S. Pat. Nos. 6,898,806 and 7,114,199 incorporate a ratchet arrangement between the hook and the body to allow discrete vertical adjustment of the device below the rim of a toilet bowl. Furthermore, U.S. Pat. No. 6,675,396 allows for continuous adjustment of the body with respect to the rim by the use of a friction fit wherein a flat bar hook is wedged within a hollow channel formed within the body.
- The previous means of adjustment, however, may not adequately position the nozzle so that the dispensed fluid reaches the extremes of the inner surface of the toilet bowl when the toilet bowl has an asymmetric or elongated rim/inner surface configuration.
- Therefore, there is a need for an improved clip for mounting a nozzle near the rim of the toilet bowl.
- The foregoing needs can be met with a clip according to the present invention for mounting a fluid delivery device. The clip is suitable for use in an automated or manual cleaning system for cleaning an enclosure, such as a toilet bowl, a shower enclosure, a bathtub enclosure, and the like. As used herein, the term “cleaning” also includes sanitizing and/or disinfecting, the term “deodorizing” also includes freshening, and the term “fluid” includes cleaning fluids, sanitizing fluids, disinfecting fluids, and the like. Furthermore, the term “fluid” is read broadly to include, liquids, gels, flowable powders, vapors, and the like. Without limitation, an example embodiment of the invention will be described with reference to a toilet bowl.
- The clip maintains the security and orientation of the fluid delivery device while in use to help ensure that the fluid is dispensed onto the desired enclosure surfaces. The clip is secured to the enclosure to prevent inadvertent or accidental movement that may cause undesired signals from the sensor and/or alter the coverage of the dispensed fluid. Additionally, the clip accommodates varying toilet sizes and shapes by adjusting for rim height, depth, angle, and curvature. Angle adjustment can be done substantially automatically as the clip is mounted to a rim. Grips on the hook help to ensure the orientation of the clip is maintained once set. Furthermore, channels are present to secure the fluid conduit to the clip to prevent pinching or kinks in the fluid conduit.
- The invention provides a clip for mounting a fluid delivery device adjacent a wall of an enclosure. In one embodiment, the clip includes a base, a hook configured to support the base adjacent the wall of an enclosure, means for attaching a fluid delivery device to the base, and means for rotating the base.
- In one aspect, the means for attaching a fluid delivery device to the base may comprises an arm extending from the body. Further, the arm may include a support segment and a barrel at the distal end of the support segment for supporting a fluid delivery device.
- In another aspect, the base may include a fluid inlet and the clip may include a fluid delivery device including a nozzle in fluid communication with the fluid inlet. The nozzle may include a deflection plate, a passageway in fluid communication with the fluid inlet at an upper end of the passageway and extending between the fluid inlet and the deflection plate, a channel in fluid communication with a lower end of the passageway, and a pair of fins flanking the channel and extending upwardly from the deflection plate that when contacted by fluid rotate the nozzle.
- In one configuration, the means for rotating the base includes a rib protruding from the hook, a channel formed in the base for receiving the hook, a slit formed in the channel comprising an entrance, an exit, and an intermediate position between the entrance and the exit for receiving the rib. Furthermore, the width of the slit decreases from the entrance to the intermediate position and increases from the intermediate position to the exit to allow relative rotation between the hook and the base about a point located near the intermediate position of the slit.
- In yet another aspect, the hook may include ratchet teeth and the channel may comprise one or more protrusions for engaging the ratchet teeth to resist sliding movement between the hook and base. In another aspect, the hook may comprise means for attaching a fluid conduit to the hook. Furthermore, the means for attaching the fluid conduit to the hook may include a channel. In a further aspect, the fluid conduit extends into the fluid inlet for delivering fluid to the fluid delivery device.
- In another embodiment of the invention, a clip for mounting a fluid delivery device adjacent a wall of an enclosure includes a base, a hook configured to support the base adjacent the wall, means for attaching a fluid delivery device to the base, and a sensor mounted on the base or the hook. In one aspect, the sensor may be a motion sensor, a proximity sensor, or the like.
- In another aspect, the means for attaching a fluid delivery device to the base comprises an arcuate arm extending downwardly from the base to rotatably support a fluid delivery device. In yet a further aspect, the sensor is mounted on the base on a surface opposite of the hook.
- In an additional embodiment, a device for spraying an inner surface of an enclosure with a fluid, includes a container for the fluid, a fluid delivery device through which the fluid can be applied to the inner surface of the enclosure, a fluid conduit in fluid communication with the container and the fluid delivery device, means for delivering fluid from the container through the fluid conduit and to the fluid delivery device, and a clip for mounting the fluid delivery device adjacent the inner surface of the enclosure; the clip comprises a base, a hook configured to support the base adjacent the inner surface, and wherein the base is configured to rotate with respect to the hook. In one aspect, the enclosure is one of a tub, a shower, a toilet, or the like.
- In a further aspect, the clip comprises a rib protruding from the hook, a channel formed in the base for receiving the hook, a slit formed in the channel comprising an entrance, an exit, and an intermediate position between the entrance and the exit for receiving the rib, and wherein the width of the slit decreases from the entrance to the intermediate position and increases from the intermediate position to the exit to allow relative rotation between the hook and the base about a point located near the intermediate position of the slit.
- In another aspect, a sensor is mounted on the hook or the base. Furthermore, the sensor may be a motion sensor, a proximity sensor, or the like.
- In a further embodiment, a method for attaching a clip for mounting a fluid delivery device adjacent a toilet bowl having a rim including an underside, comprises the steps of providing a base comprising a tab, providing a hook configured to support the base adjacent the rim, providing means for rotating the base, securing the hook to the rim, engaging the tab of the base to the underside of the rim at an interface, and rotating the base in response to the interface to substantially engage the tab of the base with the underside of the rim.
- It is therefore an advantage of the invention to provide a clip for mounting a fluid delivery device where the body of the clip is rotatable relative to the hook such that fluid is dispensed onto the inner surface of the enclosure, and further, where a sensor mounted to the hook or base helps prevent dispensing fluid during undesired periods.

- A clip according to the invention for mounting a fluid delivery device can be used in various devices that dispense fluid onto the inside surfaces of an enclosure, such as a toilet bowl, a shower enclosure, a bathtub enclosure, or the like. Various embodiments of the invention will now be described with reference to the Figures. The embodiments are shown and described for the purposes of illustration and are not intended to limit the invention in any way.
- Turning to
FIGS. 1 and 2 , there is shown an example embodiment of aclip 10 for mounting a fluid delivery device to an enclosure, here atoilet bowl 12. Theclip 10 is secured to therim 14 of thetoilet bowl 12 by ahook 16. Abase 18 is supported by thehook 16 and houses a fluid delivery device, here anozzle 20. Acontainer 22 supplies fluid via afluid conduit 24 to thefluid delivery device 20 to be dispensed onto theinside surface 26 of thetoilet bowl 12. The fluid can be supplied from thecontainer 22 to thefluid delivery device 20 in a variety of ways; for example, the fluid may be motivated by a gaseous propellant, by a pump, a syringe, or any other suitable means. Furthermore, the execution of the fluid delivery from thecontainer 22 can be controlled by a variety of methods/devices, one being a timing circuit using predetermined logic to control when the fluid is dispensed. - Turning to
FIGS. 3, 4 , and 5 thehook 16 for supporting thebase 18 and attaching theclip 10 to thetoilet bowl 12 has three main segments. Abowl segment 28, atop rim segment 30, and aninner rim segment 32. All threesegments flexible hook 16. Thebowl segment 28 has a substantially rectangular cross-section and a flaredelastomeric gripping foot 34 withelastomeric ribs 37 at a lower end for helping to secure theclip 10 to thetoilet bowl 12. Suitable elastomeric materials for thegripping foot 34 andribs 37 include, without limitation, neoprene, polyurethane rubbers, and silicone rubbers. Thebowl segment 28 extends substantially vertically upward and transitions into thetop rim segment 30 at aflexible elbow 35 that allows thehook 16 to flex predominantly in the F-F direction (shown onFIG. 3 ) to secure theclip 10 to toilet bowls of various shapes and sizes. Thetop rim segment 30 has a substantially rectangular cross-section and extends horizontal across therim 14 of thetoilet bowl 12 where it transitions into theinner rim segment 32 at anotherflexible elbow 36, also allowing thehook 16 to flex. Theinner rim segment 32 extends vertically downward from theelbow 36 and is configured to engage and support thebase 18. - The
inner rim segment 32 of thehook 16 has afront face 38 and arear face 40 joined by two short side faces 42. Arib 44 protrudes from therear face 40 of theinner rim segment 32 and extends the length thereof. As discussed in detail below, therib 44 limits the angle of rotation of the base 18 with respect to thehook 16. Therib 44 of the example embodiment has a substantially rectangular cross-section, however, therib 44 may have a curved cross-section, a square cross-section, comprise two spaced apart members, and the like. Additionally, therib 44 need not extend the length of theinner rim segment 32 provided therib 44 engages thebase 18 throughout the desired adjustable range of thebase 18. The short side faces 42 haveratchet teeth 46 used in conjunction with the base 18 to restrain vertical movement of thebase 18 along avertical axis 48. Other restraints may be used, such as a friction fit between thehook 16 andbase 18, or the like. - The
bowl segment 28 and thetop rim segment 30 include a series of C-shapedchannels 50 that restrain theconduit 24 as it is routed around the perimeter of thehook 16 on its way to thenozzle 20 in thebase 18. Thebowl segment 28 of the present embodiment includes three C-shapedchannels 50 of alternating openings. Theconduit 24 is pressed into the C-shapedchannels 50, however, thechannels 50 could be rectangular or any other suitable shape to restrain theconduit 24. Thetop rim segment 30 preferably includes onechannel 50 helping to route theconduit 24, however, more may be used if needed. - Turning to
FIGS. 3, 4 , and 6 thebase 18 has aback face 52, a pair of spaced apart side faces 54 extending forward of theback face 52, atop face 56 and afront face 58 extending between the side faces 54, and acurved face 60 extending between the side faces 54,top face 56, andfront face 58. The faces 52, 54, 56, 58, 60 define apartial cavity 62 housing a portion of thenozzle 20. Thebase 18 has atab 53 that extends rearward from theback face 52 of thebase 18. Thetab 53 helps orientate the base 18 with respect to therim 14 when theclip 10 is mounted to thetoilet bowl 12, as discussed below. Thetab 53 may be one continuous member as shown in the example embodiment, or alternatively, thetab 53 may include a plurality of members extending from thebase 18. Thebase 18 is preferably molded from plastic (e.g., polyethylene or polypropylene). - With emphasis on
FIG. 6 , thebase 18 includes achannel 64 for receiving theinner rim segment 32 of thehook 16. Thechannel 64 includes aslit 66 for receiving therib 44 having anentrance 68, anexit 70, and an intermediate position 72 (which may or may not be equidistant from theentrance 68 and the exit 70). The width of theslit 66 decreases from theentrance 68 to theintermediate position 72 and increases from theintermediate position 72 to theexit 70. In one embodiment, theintermediate position 72 is approximately half way between theentrance 68 and theexit 70; however, the narrowest point need not be halfway between theentrance 68 andexit 70, but may occur anywhere between the extremes of theslit 66. Additionally, the maximum width of theslit 66 may vary depending on the desired degree of adjustment of the base 18 with respect to thehook 16. If greater rotational adjustment of thebase 18 is desired, the maximum width of theslit 66 at theentrance 68 andexit 70 may be increased; alternatively, or in addition, the width of therib 44 may be decreased. - The
channel 64 includes a pair ofprojections 74 extending from the walls of theshort sides 65 of thechannel 64 to engage theratchet teeth 46 of thehook 16 as theinner rim segment 32 slides within thechannel 64. Theprojections 74 are configured to engage theratchet teeth 46 to inhibit vertical sliding of the base 18 with respect to thehook 16. Theprojections 74 may be rounded, terminate in a point, or other suitable geometry. Many other structures are capable of providing the desired restraint, such as a spring-loaded ball that is housed in a cavity formed in thechannel 64 to urge the ball against a contour (e.g., ratchet teeth 46) of thechannel 64. The engagement between theprojections 74 and theratchet teeth 46 is such that thebase 18 is capable of the desired rotation (discussed below) without causing theprojections 74 and ratchetteeth 46 to disengage. - The base 18 further includes a means to attach a fluid deliver device (e.g., a nozzle 20). In the example embodiment, the
nozzle 20 is restrained laterally between afluid inlet 80 and abarrel 78. Thebase 18 includes anarm 76 extending downward from thebase 18. Thearm 76 has a flatbar support segment 77 with a J-shaped bend extending forward with abarrel 78 located at the distal end of thesupport segment 77. Thebarrel 78 includes a tubular recess for receiving the bottom of thenozzle 20. The base 18 also has afluid inlet 80 located in thecurved face 60 that tapers from the opening (shown inFIG. 3 ). Thefluid inlet 80 and thebarrel 78 are used in conjunction to restrain lateral movement of thenozzle 20, but allow thenozzle 20 to rotate about thenozzle axis 82. - A
sensor 98 for sensing the environment surrounding theclip 10 may be mounted to the base 18 orhook 16. Preferably, thesensor 98 is mounted substantially to thefront face 58, but may be mounted on theangled face 60 or any other suitable location providing a view, for example, of the user to accurately determine the presence or absence thereof. Thesensor 98 may be a motion sensor, proximity sensor, or the like. Thesensor 98 is preferably electrically connected to thecontainer 22 and/or controller (not shown) to influence when the fluid is dispensed to thetoilet bowl 12 based upon predetermined logic. It should be appreciated that the sensor can be omitted from theclip 10 in certain embodiments if the sensing function is not desired. - Turning to
FIG. 8 , an embodiment of thefluid delivery device 20 is described. Thefluid delivery device 20 is preferably molded from plastic (e.g., polyethylene and polypropylene). Thenozzle 20 includes acircular deflection plate 84, apassageway 86 extending upwards from thedeflection plate 84 and in fluid communication with thefluid inlet 80. Achannel 88 extends radially outward from thepassageway 86 near thedeflection plate 84 and angles away from theinitial channel 88 path at point A as shown inFIG. 8 . Thechannel 88 is flanked by a pair offins 90 that extend upwardly from thedeflection plate 84. The contour of thechannel 88 andfins 90 may vary depending on the desired rotational speed of thenozzle 20, pressure of the fluid, and the like. - As shown most clearly in
FIGS. 3 and 8 , thenozzle 20 is restrained laterally in thebase 18 by inserting aspindle 92 extending from the underside of thedeflection plate 84 into the recess in thebarrel 78 of thearm 76 and by inserting the tapered end of thefluid inlet 80 into thepassageway 86 where it abuts aledge 94 formed in thepassageway 86. Thenozzle 20 is free to rotate about thenozzle axis 82, but is restrained from lateral movement. - The means for attaching the fluid delivery device may include a
fluid delivery device 20 suspended from thebase 18 without the use of anarm 76. The fluid delivery device, here anozzle 20, may be snap-fit to thebase 18, screwed to thebase 18, wedged to thebase 18, and the like. Furthermore, an arcuate arm (not shown) may extend from the base 18 to support thefluid delivery device 20. - In operation, fluid is moved from the
container 22 through theconduit 24, which is routed through thechannels 50 along thehook 16, and into thefluid inlet 80 on thebase 18. Fluid flows into the top of thenozzle 20, down thepassageway 86 where it is directed radially outward by thechannel 88. As the fluid exits thechannel 88 its path is altered by theangled fins 90 flanking thechannel 88. The reaction causes thenozzle 20 to rotate counterclockwise as viewed inFIG. 8 . As a result, the fluid is expelled radially outward from thenozzle 20 onto theinside surface 26 of thetoilet bowl 12. - With the general structure and operation of the fluid delivery device described, we turn our attention to the means for rotating the
base 18 and thus adjusting the area covered by the fluid dispensed from thenozzle 20. Returning toFIGS. 4 and 6 , and with reference toFIG. 7 , thebase 18 can be rotated relative to thehook 16 about ahorizontal axis 96 extending substantially normal from a plane defined by thevertical axis 48 and theback face 52 of thebase 18. Theslit 66 formed in thechannel 64 is flared at theentrance 68 andexit 70. This allows the base 18 to rotate near theintermediate position 72 about thehorizontal axis 96 until therib 44 protruding from thehook 16 abuts the slit sides 45 formed in theback face 52. - For example, with reference to
FIG. 7 , when thebase 18 is rotated by an angle R1 with respect to the vertical axis 48 (shown by dashed lines) the relative placement of thenozzle 20 is angled accordingly, thus altering the area covered by the fluid dispensed from thenozzle 20. Additionally, when thebase 18 is rotated by an angle R2 in the opposite direction, the coverage of the fluid dispensed by thenozzle 20 is again altered. As thebase 18 rotates, theprojections 74 slide within a respective tooth of theratchet teeth 46; thus, the fit between theprojections 74 and theratchet teeth 46 should allow for the base 18 to rotate freely while also inhibiting vertical movement of thebase 18. This rotational adjustment allows theclip 10 to accommodate toilets and enclosures of varying geometries. - The means for rotating the base 18 need not include a
slit 66 as described. For example, theback face 52 may include several pairs of opposed fingers in the plane defined by theback face 52 for restraining the rotation of therib 44 of thehook 16. The opening between a pair of opposed fingers near the entrance and the opening of a pair of opposed fingers near the exit are larger than the opening between a pair of opposed fingers located between the entrance and exit fingers. As a result, thebase 18 is capable of rotating until therib 44 engages the fingers near the entrance and exit. In another embodiment, theslit 66 may have a V-shape wherein the entrance tapers to the exit, or the opposite. Thus, the point of rotation of thebase 18 is located near the exit of theslit 66, or smaller of the entrance and exit. Again, the rotation of thebase 18 is limited by therib 44 engaging the slit sides 45. - The rotational adjustment of the base 18 may be performed manually by a user of the
clip 10 or automatically as theclip 10 is mounted to the enclosure, here atoilet bowl 12. With general reference toFIGS. 1-4 , 6, and 7, theclip 10 is mounted substantially as follows. Theclip 10 is secured to therim 14 of thetoilet bowl 12 by urging thehook 16 in the F-F direction away from thebase 18 and placing theclip 10 over therim 14. Once thehook 16 is secured, thebase 18 is slid along thevertical axis 48 up thehook 16 and ratchetteeth 46 until thetab 53 engages the underside of therim 14. As thetab 53 of thebase 18 continues to engage the underside of therim 14, thebase 18 is rotated about thehorizontal axis 96, thus aligning thenozzle 20 with the plane of the underside of therim 14 and helping to ensure that the fluid from thenozzle 20 is dispensed onto theinside surface 26 of the toilet bowl 12 (assuming the plane of the underside of therim 14 is parallel with the plane defined by the topside of the rim 14). Thetab 53 may further include anelastomeric grip 51 protruding from the distal end of thetab 53 helping to secure the base 18 in its engaged position on therim 14. The base 18 need not include atab 53; in this embodiment, thebase 18 may be manually rotated by the user to adjust the base 18 with respect to thehook 16. - Turning now to
FIGS. 9-11 , there is shown another example embodiment of aclip 110 for mounting a fluid delivery device to an enclosure such as a toilet bowl. Theclip 110 is secured to the rim of the toilet bowl by a hook 116 (which is omitted in the view ofFIG. 11 ) in the same manner as theclip 10 ofFIGS. 1-8 . Abase 118 is supported by thehook 116 and supports a fluid delivery device, here anozzle 120. A container supplies fluid via a fluid conduit to thefluid delivery device 120 to be dispensed onto the inside surface of the toilet bowl in the same manner as theclip 10 ofFIGS. 1-8 . The fluid can be supplied from the container to thefluid delivery device 120 in a variety of ways; for example, the fluid may be motivated by a gaseous propellant, by a manual or electric pump, a syringe, or any other suitable means. Furthermore, the execution of the fluid delivery from the container can be controlled by a variety of methods/devices, one being a timing circuit using predetermined logic to control when the fluid is dispensed. - Referring still to
FIGS. 9-11 , thehook 116 for supporting thebase 118 and attaching theclip 110 to the toilet bowl has three main segments. Abowl segment 128, atop rim segment 130, and aninner rim segment 132. All threesegments flexible hook 116. Thebowl segment 128 has a substantially rectangular cross-section and a flared elastomericgripping foot 134 withelastomeric ribs 137 at a lower end for helping to secure theclip 110 to the toilet bowl in the same manner as theclip 10 ofFIGS. 1-8 . Suitable elastomeric materials for thegripping foot 134 andribs 137 include, without limitation, neoprene, polyurethane rubbers, and silicone rubbers. Thebowl segment 128 extends substantially vertically upward and transitions into thetop rim segment 130 at aflexible elbow 135 that allows thehook 116 to flex (as in the F-F direction shown onFIG. 3 ) to secure theclip 110 to toilet bowls of various shapes and sizes. Thetop rim segment 130 has a substantially rectangular cross-section and extends horizontally across the rim of the toilet bowl where it transitions into theinner rim segment 132 at anotherflexible elbow 136, also allowing thehook 116 to flex. Theinner rim segment 132 extends vertically downward from theelbow 136 and is configured to engage and support thebase 118. Thebowl segment 128 and thetop rim segment 130 include a C-shapedchannel 150 that restrains the fluid conduit as it is routed around the perimeter of thehook 116 on its way to thenozzle 120 in thebase 118. The fluid conduit is pressed into the C-shapedchannel 150 in the same manner as theclip 10 ofFIGS. 1-8 . Thebase 118 has aback face 152, a pair of spaced apart side faces 154 extending forward of theback face 152, atop face 156 and afront face 158 extending between the side faces 154. The faces 152, 154, 156, 158 define a cavity. Thebase 118 is preferably molded from plastic (e.g., polyethylene or polypropylene). - The
base 118 includes achannel 164 for receiving theinner rim segment 132 of thehook 116. Thechannel 164 is structured similar to thechannel 64 of theclip 10 ofFIGS. 1-8 , and thechannel 164 and thehook 116 provide rotational adjustment of the base 118 using the same construction in the same manner as theclip 10 ofFIGS. 1-8 so the means for rotational adjustment of theclip 110 will not be explained further. - A
sensor 198 for sensing the environment surrounding theclip 110 may be mounted to thebase 118. Preferably, thesensor 198 is mounted substantially to thefront face 158, but may be mounted on any other suitable location providing a view, for example, of the user to accurately determine the presence or absence thereof. Thesensor 198 may be a motion sensor, proximity sensor, or the like. Thesensor 198 is preferably electrically connected to the container and/or controller (not shown) to influence when the fluid is dispensed to the toilet bowl based upon predetermined logic. - Looking at
FIG. 12 , the base 118 further includes a means to attach a fluid delivery device (e.g., nozzle 120) to thebase 118. In the example embodiment, thenozzle 120 is restrained laterally between abarrel 178 and afluid inlet 180. Thebase 118 includes anarm 176 extending downward from thebase 118. Thearm 176 has acurved section 177 with a J-shaped bend extending forward to thebarrel 178 located at the distal end of thecurved section 177. Thefluid inlet 180 and thebarrel 178 are used in conjunction to restrain lateral movement of thenozzle 120, but allow thenozzle 120 to rotate about thenozzle axis 182. The tubularfluid inlet 180 defines aflow path 181, and extends downwardly from alower base floor 202 that is attached to thebase 118. Thebase floor 202 includes an upwardly extendingtubular sleeve 204 that defines aflow path 205. Thebase 118 is also attached to afluid supply port 208 that defines aflow path 209. Thefluid supply port 208 and thetubular sleeve 204 are snap fit together with an O-ring 211 therebetween to create fluid tight seal. Thefluid supply port 208 is located in arecess 213 in thetop face 156 of the base, and may be connected to a fluid conduit (such asconduit 24 inFIG. 3 ). - Referring to
FIGS. 10 and 12 and 13, thenozzle 120 is shown in greater detail. Thenozzle 120 is preferably molded from plastic (e.g., polyethylene and polypropylene). Thenozzle 120 includes acircular deflection plate 184. Anaxial spindle 192 extends downward from thedeflection plate 184. Spaced apartwalls deflection plate 184. In the embodiment ofFIG. 13 , thewalls deflection plate 184 from opposed outer edges of thedeflection plate 184. A centralfluid deflection peak 191 extends upward from thedeflection plate 184 between thewalls wall 190 a has a generally U-shaped (when viewed in vertical cross-section) inwardly directeddepression 193 a, and the top of thewall 190 b has a generally U-shaped (when viewed in vertical cross-section) inwardly directeddepression 193 b. Apassageway 186 is defined by thewalls passageway 186 extends upwards from thedeflection plate 184 and in is fluid communication with thedepressions channel 188L extends radially outward from thepassageway 186 near thedeflection plate 184 and angles rearwardly away from theinitial channel 188L path at point A as shown inFIG. 13 . Achannel 188R extends radially outward from thepassageway 186 near thedeflection plate 184 and angles forwardly away from theinitial channel 188R path at point B as shown inFIG. 13 . The contour of thechannels walls nozzle 120, the pressure of the fluid, the flow rate of the fluid, and the like. - As shown most clearly in
FIG. 12 , thenozzle 120 is restrained laterally by inserting aspindle 192 into arecess 179 in thebarrel 178 of thearm 176 and by inserting the end of thefluid inlet 180 betweendepressions nozzle 120 is free to rotate about thenozzle axis 182, but is restrained from lateral movement. - In operation, fluid is moved from a container through a fluid conduit (see, for example, the
container 22 and theconduit 24 ofFIG. 1 ) and into thefluid supply port 208. Looking atFIG. 12 , the fluid flows through theflow paths fluid inlet 180. (The diameter of the exit orifice of the fluid inlet can dictate the pressure which helps to dictate the spin rate and the distance of fluid travel off thenozzle 120.) Fluid flows onto the top of thefluid deflection peak 191 and down the forkedpassageways 186 where it is directed radially outward by thechannels channels inner surfaces channels nozzle 120 to rotate counterclockwise as viewed inFIG. 13 . As a result, the fluid is expelled radially outward from thenozzle 120 onto the inside surface of the enclosure such as a toilet bowl. - Referring to
FIGS. 14 and 15 , another embodiment of anozzle 220 is shown in greater detail. Thenozzle 220 is preferably molded from plastic (e.g., polyethylene and polypropylene). Thenozzle 220 includes a circular (from a top view)deflection plate 284. Anaxial spindle 292 extends downward from thedeflection plate 284. Spaced apartwalls deflection plate 284. In the embodiment ofFIGS. 14 and 15 , thewalls outer edge point 277L of thedeflection plate 284 to a location spaced inward from anouter edge point 277R of thedeflection plate 284. A central fluid deflection peak 291 (similar tofluid deflection peak 191 ofFIGS. 12 and 13 ) extends upward from thedeflection plate 284 between thewalls wall 290 a has a generally U-shaped inwardly directed depression (similar to inwardly directeddepression 193 a inFIGS. 12 and 13 ), and the top of thewall 290 b has a generally U-shaped inwardly directed depression (similar to inwardly directeddepression 193 b inFIGS. 12 and 13 ). - Still referring to
FIGS. 14 and 15 , a passageway 286 (similar topassageway 186 inFIGS. 12 and 13 ) is defined by thewalls passageway 286 extends upwards from thedeflection plate 284 and in is fluid communication with the depressions in thewalls FIGS. 12 and 13 ) extends radially outward from thepassageway 286 near thedeflection plate 284 and angles rearwardly away from the initial channel as inFIG. 13 . Achannel 288R extends radially outward from the passageway 286 (similar to channel 188R inFIGS. 12 and 13 ) and angles forwardly away from theinitial channel 288R path as shown inFIG. 15 . Thedeflection plate 284 has a dishedfloor 276 that creates a draft angle Z (seeFIG. 14 ) at the outer edge of the top of thedeflection plate 284. The contour of the draft angle Z, the channels, and thewalls nozzle 220, the pressure of the fluid, the flow rate of the fluid, and the like. - Similar to
FIG. 12 , thenozzle 220 may be restrained laterally by inserting thespindle 292 into arecess 179 in thebarrel 178 of thearm 176 and by inserting the end of thefluid inlet 180 between upper depressions in thewalls nozzle 220 is free to rotate about the nozzle axis, but is restrained from lateral movement. In operation, fluid is moved from a container through a fluid conduit (see, for example, thecontainer 22 and theconduit 24 ofFIG. 1 ) and into thefluid supply port 208 as inFIG. 12 , the fluid flows through theflow paths fluid inlet 180. Fluid flows onto the top of thefluid deflection peak 291 ofnozzle 220 and down the forkedpassageways 286 where it is directed onto thefloor 276 and radially outward by the channels. As the fluid exits the channels, the fluid path is altered by the angled inner surfaces of thewalls nozzle 220 to rotate right in direction R as inFIG. 15 . The fluid continues to flow on thefloor 276 and then moves up the draft angle at the edge of thedeflection plate 284 to create a slightly upward travel path for the fluid. As a result, the fluid is expelled radially outward from thenozzle 220 onto the inside surface of the toilet bowl, with the slightly upward travel path for the fluid allowing for under the toilet rim contact of the fluid with the inner surface of the toilet bowl even after 18 or more inches of travel. - Comparing
FIGS. 8, 13 and 14, thenozzle 20, thenozzle 120, and thenozzle 220 have differences in structure that can lead to different operating characteristics. For example, thenozzle 20 has asingle channel 88 extending away from thepassageway 86, whereasnozzle 120 andnozzle 220 have two channels extending away from the central passageway. The extra passageway can serve to get maximum work out of the nozzle and improve efficiency. Thenozzle 120 andnozzle 220 also have fluid deflection peaks 191, 291 that can improve efficiency. Comparingnozzle 120 andnozzle 220, it can be seen that thewalls nozzle 120 extend all the way across thedeflection plate 184 from opposed outer edges of thedeflection plate 184, whereaswalls nozzle 220 are spaced inward from opposed outer edges of thedeflection plate 284. The spacing of the walls from the edge of the plate can create more tangential motion in the fluid expelled from thenozzle 220. The centripetal force causes fluid to spin and shear off. Also, the draft angle Z at the outer edge of thenozzle 220 can provide for a spray of about 18 inches without having the level of liquid spray drop down. This is advantageous as it prevents the spray from failing down so far that it does not hit under the upper areas under the toilet rim. - Various parameters of the
nozzles nozzles nozzles - Turning now to
FIG. 16 , there is shown a side view of anotherhook 216 suitable for use with the clip ofFIG. 9 . Thehook 216 has three main segments, i.e., abowl segment 228, atop rim segment 230, and an inner rim segment 232. All threesegments bowl segment 128 has a substantially rectangular cross-section and a flared elastomericgripping foot 234 with oblongelastomeric ribs 237 at a lower end for helping to secure thehook 216 to the toilet bowl in the same manner as theclip 10 ofFIGS. 1-8 . Suitable elastomeric materials for thegripping foot 234 andribs 237 include, without limitation, neoprene, polyurethane rubbers, and silicone rubbers. Thebowl segment 228 extends substantially vertically upward and transitions into thetop rim segment 230 at aflexible elbow 235 that allows thehook 216 to flex. Thetop rim segment 230 has a substantially rectangular cross-section and extends horizontally across the rim of the toilet bowl. - Still referring to
FIG. 16 , the inner rim segment 232 of thehook 216 is configured to engage and support the base 118 as described above with reference to the embodiment of theclip 110 ofFIGS. 9-15 . The upper end of the inner rim segment 232 has a lateral generallyrectangular passageway 236 that extends through the inner rim segment 232. Adistal end 238 of thetop rim segment 230 is inserted in thepassageway 236 such that thebowl segment 228 and the inner rim segment 232 are movable toward and away from each other. This horizontal expansion and contraction of thehook 216 further accommodates various toilet bowl rim width sizes. Also, the inner surface of thebowl segment 228 includes asuction cup 239, and the inner surface of thetop rim segment 230 includes asuction cup 241. Thebowl segment 228 may be adhered to thetoilet rim 14 bysuction cup 239, and thetop rim segment 230 may be adhered to thetoilet rim 14 bysuction cup 241. - Thus, the present invention provides a clip for mounting a fluid delivery device where the base of the clip is rotatable relative to the hook such that fluid is dispensed onto the inner surface of the enclosure, and further, where a sensor prevents dispensing fluid at undesired periods. As a result, full coverage of the fluid around the inner surface of the enclosure is possible during preferred periods.
