With reference now to the drawing figures in which like reference numerals designate like parts throughout the disclosure.
According to the embodiment illustrated, lavatory system 10 includes two washing stations (e.g., hand washing stations), shown as a first or upper station 12 and a second or lower station 14, mounted to a base (e.g., housing, cabinet, etc.). Alternatively, the lavatory system may include any number of washing stations (e.g., one, three, four, or more) arranged in any of a variety of configurations (e.g., all upper stations, all lower stations, mixed upper/lower stations, etc. set at a variety of upper/lower patterns, heights (“H” in
Upper station 12 and lower station 14 may be configured to have different heights to accommodate persons having varying abilities or characteristics for using a lavatory system (e.g., disabled, tall, short, etc.). In one embodiment, upper station 12 has a height (e.g., the distance from the floor to the upper surface of the counter surrounding the basin) that is greater than 34 inches (e.g., about 36 inches) and lower station 14 has a height that is about 34 inches to accommodate an adult user in a wheelchair. In another embodiment, lower station 14 has a height that is about 31 inches to accommodate a juvenile user in a wheelchair. In another embodiment, lower station 14 has a height that is less than 31 inches (e.g., about 28 inches). In another embodiment, upper station 12 has a height that is about 34 inches, and lower station 14 has a height that is about 31 inches. In other embodiments, lavatory system 10 may include any number of hand washing stations (e.g., 3, 4, 5, etc.), each hand washing station located at one of the heights discussed above.
The embodiment illustrated further includes a housing 31. Housing 31 includes a shelf or platform (shown as a panel 36) located above the other components of the washing stations, a front portion 33, and side portions 35. Housing 31 generally defines an interior portion 37 of lavatory system 10 (shown in
Preferably, the one or more of the fixtures are “touchless”, meaning that a user can operate the fixtures without physically contacting the fixtures and/or an interface coupled to the fixtures (i.e., “hands-free” operation). In this manner, the lavatory system is intended to overcome sanitation and/or accessibility limitations often associated with many conventional fixtures. The control system monitors a defined sensing region (an area adequately proximate to the fixtures in which a user of the fixture is likely to be positioned) for the presence of an object (e.g., a user, the user's hand, etc.) and controls the operation of the fixtures accordingly. The control system includes a power supply system, a detection system, and a fixture actuation system. In one embodiment, each washing station includes one or more sensors 29 (rear portion of one sensor 29 is shown in
According to an exemplary embodiment, the lavatory system 10 is configured to inhibit or prevent inadvertent activation of one or more fixtures (e.g., faucets 20, soap dispensers 30, hand dryers 28, etc.). According to an exemplary embodiment, lavatory system 10 includes a control system to control the operation and activation of the various fixtures (e.g., faucets 20, soap dispensers 30, hand dryers 28, etc.) via user interaction with sensors 29. Since the fixtures are integrated and located around basin 16 at each wash station, it is preferred that the fixtures are not inadvertently activated during use of other fixtures. The control system includes one or more sensors 29, as discussed above, in communication with a control circuit (e.g., controller, processor, etc.), which is in communication with the fixtures. The control circuit may be configured (e.g., hardwired, programmed, etc.) to allow activation of only one fixture at a time, allow activation of certain two fixtures at a time (e.g., faucet and soap dispenser), or sequence the fixture activation at predetermined or calculated times and intervals. In addition, the control circuit may be configured to turn off one or more of the fixtures (e.g., the faucet and/or the soap dispenser) when another of the fixtures is activated (e.g., the hand dryer). For example, a flow sensor that detects the flow of water through faucet 20 can be used to disconnect the power from hand dryer 28. Alternatively, the sensor 29 associated with hand dryer 28 communicates with the faucet sensor using signals through optoisolators to activate and deactivate hand dryer 28. This communication may allow the control circuit to prevent the activation of faucet 20 and/or soap dispenser 30 when hand dryer 28 has been activated. Alternatively, there is no control interaction among the fixtures (i.e., independent operation). The sensors may be directed to provide a sensed area or zone that does not overlap with the sensed zones for other fixtures.
Referring to
At step 216, the control system determines if the motor of hand dryer 28 is active. In one embodiment, the motor of hand dryer 28 may be activated by the sensor 29 associated with hand dryer 28 detecting the presence of a user's hand near hand dryer 28. In another embodiment, the motor of hand dryer 28 may be activated by other means such as by manual activation by a user via a switch or button. If, during step 216, the control system determines that the motor of hand dryer 28 is active, the control system proceeds to step 218. During step 218, the control system closes the valve associated with faucet 20 to stop water from flowing through faucet 20 as quickly as possible. Thus, during step 218, the faucet shutdown procedure initiated during step 210 is truncated or shortened when the user of lavatory system 10 switches from using faucet 20 to using hand dryer 28. However, if during step 216, the control system determines that the motor of hand dryer 28 is not active, the control system proceeds to step 220. At step 220, the control system detects whether the faucet shutdown procedure is complete. If the faucet shutdown procedure is complete, the control system returns to step 200. If the faucet shutdown procedure is not complete, at step 222 the faucet shutdown procedure is continued by returning to step 212. Steps 212 through 222 are repeated until faucet shutdown is complete.
According to an exemplary embodiment, the lavatory system includes one or more integrated hand washing stations. Each hand washing station includes a basin, a faucet, a solenoid valve configured to control water flow to the faucet, and a electric hand dryer located adjacent the basin and the faucet so that the user of the washing station may use the faucet and the electric hand dryer without leaving the washing station. The electric hand dryers include an outlet to direct air across the associated basin so that any water that drips from the user's hands will fall within the basin. The system further includes a control system configured to control activation of the solenoid valve and the electric hand dryer, wherein the control system is configured to inhibit simultaneous activation of the solenoid valve and the hand dryer. For example, the control system may be configured to prevent activation of the electric hand dryer when the solenoid valve has been activated; prevent activation of a soap dispenser when the solenoid valve and/or the hand dryer has been activated. The activation of the various fixtures may be according to a predetermined timing and sequence (e.g., an algorithm that activates fixtures based on sensed conditions or other factors). The control system may be in communication with a single sensor dedicated (directed) to each wash station that is configured to sense the presence of the user's hands near the hand washing station. Alternatively, each wash station may include a sensor to detect the presence of a hand of the user proximate that station's faucet, another sensor to detect the user's hand proximate that station's soap dispenser, and/or another sensor to detect the presence of a hand of the user proximate that station's electric hand dryer, wherein the control system activates the solenoid valve and the hand dryer based on signals received from the first sensor and second sensor according to a predetermined timing and sequence.

Housing 40 has generally vertical sides 48, an angled front panel or front side 50 and is configured to contain a paper towel roll 52 being dispensed as well as additional storage for extra paper towel rolls 54 or other supplies. Angled front side 50 has a top portion that extends further from wall 11 than the bottom portion of front side 50. Angled front side 50 is intended to provide an aesthetic appearance consistent with other design aspects of lavatory system 10 as well as additional clearance for users in wheelchairs or having other needs. Access panel 42 allows access (visual and/or physical) to the interior of towel dispenser 38, and is coupled to the housing by a hinge 56 and a lock 58.
Upper shelf 44 may be a generally horizontal panel facing in a generally upward direction, as shown in
Lower shelf 46 may be a generally horizontal panel facing in a generally upward direction. Lower shelf 46 includes an opening 60 through which paper towel is dispensed to be accessed by the user of lavatory system 10. According to an exemplary embodiment, lower shelf 46 is formed with a recess 62 where outer peripheral edge 64 is vertically above the bottom surface of recess 62. Opening 60 for the paper towel is defined by a flange or rim 66 that extends upward from and above the bottom surface of recess 62. Water that drips off a user's hands is then retained in recess 62 and allowed to evaporated to prevent water from accumulating on floor 13 or from wetting the unused paper towels.
Roll of paper towel 52 is supported on a panel or shelf 68 located within housing 40. Roll of paper towels 52, 54 may be comprised of a plurality of sheets or sections separated by perforations 70 or other means to demark separate sheets. An end 72 of paper towel roll 52 (i.e., the next sheet to be used) extends or projects upwardly through opening 60 (e.g., aperture, hole, etc.) in lower shelf 46 and is presented to the user. Roll of paper towel 52 dispenses in a generally vertical direction. The user grasps end portion 72 extending from dispenser 38, pulls in a vertical direction and/or a non-vertical direction (e.g., horizontally, diagonally, etc.). The sheet being grasped by the user separates at perforation 70, leaving another end portion extending from dispenser 38 as before.

Upper track 82 is an elongated U-shaped member (e.g., channel). Middle portion 88 of the U-shaped member includes a plurality of spaced-apart slots 90. The plurality of slots 90 are configured to provide a variety of locations to mount lavatory system 10 to wall 11 (i.e., fasteners able to engage building structure such as “studs” without limiting the relative position of the overall lavatory system relative to the studs). Upper leg 92 and lower leg 94 of the U-shaped member includes a plurality of notches or recesses 96 grouped together in pairs located along the longitudinal axis of upper track 82. Located within each pair of recesses 96 is a V-shaped centerline notch 98 located mid-way between the associated recesses 96. Preferably, there is an indicia 100 identifying the associated pair of recess 96 (e.g., location marker for the basin frame). Such indicia may be a groove on the outer surface (e.g., etched, lasered, machined, etc.).
Mounting frame 84 couples to upper track 82 and is configured to support one or more hand washing stations (e.g., sink, trap cover, backsplash, etc.), waste receptacles, towel dispensers, top shelf, cabinets, outer housings (e.g., “skin”, shell, etc.), or other fixtures or modules provided with lavatory system 10. Mounting frame 84 includes a pair of basin supports 102 (e.g., members, brackets, etc.), a pair of vertical members 104 (e.g., tracks, channels, members, etc.), and a backsplash support member 106 connecting vertical members 104. Basin support 102 includes a horizontal member 108 extending from one of the vertical members 104, and an angled member 110 extending from a lower portion of the vertical member 104 and coupled to the horizontal member 108 (i.e., to form a right triangle). Backsplash support 106 is generally a horizontally-orientated U-shaped bracket with outer legs 112 coupled to the respective vertical members (e.g., with fasteners, welding, etc.). Middle portion 114 of the U-shaped bracket includes one or more apertures to receive fasteners for coupling to backsplash 18. Vertical members 104 include a plurality of spaced apart recesses 116 configured to engage (e.g., mate, fit, register, etc.) with recesses 96 on upper track 82. Vertical members 104 have indicia 118 indicating which recesses 96 to use for the desired height H of the basin (e.g., 28 inches, 31 inches, or 34 inches) associated with the ADA regulatory requirements.
Lower track 86 is an elongated U-shaped member (e.g., channel). The middle portion of the U-shaped member includes a plurality of spaced-apart slots. According to a preferred embodiment, the lower track is identical to the upper track to minimize individual parts/components.
Other fixtures, accessories, modules, and the like may also be attached to the upper track and lower track. For example, towel dispenser 38 shown in
Because upper track 82 is attached to wall 11 or to other support structures at a predetermined height above floor 13, mounting frames 84 may then be coupled to upper track 82 at any of a variety of prescribed locations or positions depending on the heights H desired for basins 16. As shown in
Outer housing 31 generally prevents access to interior portion 37 of lavatory system 10 and to the various portions of lavatory system 10 located within interior portion 37. However, certain components of lavatory system 10 may be configured to allow access to various portions of interior portion 37. For example, as discussed above, towel dispenser 38 includes a hinged access panel 42 to allow access to the portion of interior portion 37 defined by the housing of towel dispenser 38. Panel 36 is configured to articulate between opened and closed positions. As shown in
Hinge member 130 includes a first spring 144 and a second spring 146. First spring 144 is connected between the pin joint joining second link 140 to third link 142 and a connection point 148. Second spring 146 is connected between the second end of third link 142 and the lower end of arm 150.
Referring to
As shown in
In the closed position, first link 138 and second link 140 are in substantial axially alignment allowing first link 138 and second link 140 to resist the forces exerted by first spring 144 and second spring 146. The application of an upward force to rod 134 causes first link 138 and second link 140 to come out of axial alignment. This allows first spring 144 to contract and second spring 146 to expand. The contraction of first spring 144 and the expansion of second spring 146 cause hook member 152 to disengage cylindrical projection 154 and also moves panel 36 away from wall 11. With panel 36 moved away from wall 11 and with hook 152 disengaged from cylindrical projection 154, panel 36 may be rotated to the open position of
With panel 36 in the open position, access to interior portion 37 is permitted via the upper end of housing 31. Access to interior portion 37 may be desirable for a variety of purposes, such as to repair wiring and plumbing, to replace or refill soap, paper towels, etc. To move panel 36 to the closed position, the process is reversed. In this embodiment, rod 134 is hidden from view from outside of lavatory system 10. Thus, only people who know the position of rod 134 will be likely to obtain access to interior portion 37. In addition, this limited access is achieved without the need for locks, keys, etc.
According to an exemplary embodiment, the faucets (e.g., valve, sensor, etc.) and soap dispensers (e.g., valve, sensor, etc.) are powered by a photovoltaic cell and a power management system such as disclosed in U.S. patent application Ser. No. 11/041,882 titled “Lavatory System” filed Jan. 21, 2005 (Attorney Docket No. 063359-0345) is hereby incorporated herein by reference in its entirety. The hand dryers are powered by an AC power line. The electric hand dryers may be powered by the photovoltaic system as well (e.g., battery or other energy storage element that is charged by the photovoltaic cell array).
The photovoltaic system is capable of converting light energy to electrical energy, and can be used to power one or more of the fixtures and/or the control system providing for the “hands-free” operation of fixtures. The photovoltaic system may include one or more photovoltaic cells (such as an array of cells) coupled to a support structure (e.g., the panel, shelf, etc.) on the base of the lavatory system. The photovoltaic cells may be supported by, mounted to, contained within, and/or integrally formed with a portion of support structure (e.g., the panel, countertop, basins, etc.) or other surrounding structures (e.g., a mirror, etc.). Preferably, photovoltaic cells are provided at the shelf of upper portion of support structure in an effort to maximize the exposure of the photovoltaic cells to the ambient light. Preferably, the addition of photovoltaic cells to the shelf does not significantly limit the functionality of the shelf as a usable surface for a user. The photovoltaic cells are electrically coupled to the fixtures and/or a control system providing for the operation of the fixtures.
The power management system is intended to provide for an efficient use of the electrical energy generated by the photovoltaic cells. The power management system generally includes an energy storage element configured to receive and store electrical energy generated by the photovoltaic cells, a detector (shown as a voltage detector) for monitoring the level of ambient light surrounding the lavatory system (e.g., by monitoring the energy stored in an energy storage element, etc.) to recognize periods of time when it is unlikely that the lavatory system will be used (e.g., when the ambient light is turn off or otherwise reduced), a switch capable of electrically disconnecting energy storage element from the control system when the voltage detector sends an output signal indicating that given the level of ambient light surrounding the lavatory system it is unlikely that the lavatory system will be used, and a voltage regulator for adjusting the voltage being sent to the control system. According to various alternative embodiments, power management system may be used without photovoltaic cells to electrically disconnect an energy storage element (such as a battery) from the control system.
Each lavatory system includes a deck, a mounting arrangement configured to attach the lavatory system to an adjacent wall, a drain system disposed below deck, and a cover configured to enclose plumbing system. The lavatory system may be configured for attachment to a surface (such as the wall of a restroom or other area where it may be desirable to provide a lavatory services) with a plurality of connection points. Alternatively, the lavatory system may be configured as a free-standing structure. Adjacent wall 11 may be provided with the plumbing source (including both (or either) a hot and cold water supply, preferably combined with a thermostatic mixing valve, or a tempered water supply, a drain, etc.) and an optional source such as an electrical outlet (preferably providing 110 volts GFCI).
According to an exemplary embodiment, the deck includes a countertop with a backsplash extending upwardly from the countertop, and a front apron extending downwardly from countertop. According to another exemplary embodiment, the countertop may be configured in any of a variety of constructions intended to promote the drainage of spilled or splashed water to the drain from the countertop. The countertop may include an upper surface of a lower station and an upper surface of an upper station. According to an exemplary embodiment, the countertop includes a curved surface configured to prevent water from collecting (or “ponding”), to allow excess, splashed (or spilled fluids) to drain toward a bowl or drain, and to facilitate clean-up. According to exemplary embodiments, the countertop deck may have a radiused surface, a sloped surface, a pitched surface, or the like, and/or arranged at a variety of heights.
The lower station and the upper station are configured to provide lavatory service and to accommodate persons having varying abilities for using the lavatory system (e.g., disabled, tall, short, etc.). According to any preferred embodiment, one or more stations of the lavatory system are mounted at a standard height that is designed to comply with applicable accessibility standards, such as the Americans with Disabilities Act (ADA) Accessibility Guidelines for Buildings and Facilities and Uniform Accessibility Standards for Lavatories, or other standards (e.g., Texas Accessibility Standards or TAS). According to a particularly preferred embodiment, the height of the upper surface of the deck is approximately 34 inches (865 millimeters), provides a lower clearance (i.e., from the floor to the bottom of the apron) of at least 29 inches (735 millimeters) or less above the floor, and is equipped with a set of ADA or other accessibility regulation compliant faucet assemblies. According to any preferred embodiment, the lavatory system is mounted with a counter surface no higher than thirty-one inches.

According to the embodiment illustrated, lavatory system 10 includes two hand washing stations, shown as a first or upper station 12 and a second or lower station 14. Alternatively, the lavatory system may include any number of washing stations (e.g., one, three, four, or more) arranged in any of a variety of configurations (e.g., all upper stations, all lower stations, mixed upper/lower stations, etc. set at a variety of upper/lower patters or sequences). Each hand washing station 12, 14 generally includes a basin 16 (e.g., bowl, sink, receptacle, etc.), a countertop 41 or surface (e.g., rim, ledge, etc.) at least partially surrounding the basin, washing fixtures (e.g., faucet 20, soap dispenser 30, etc.) associated with each basin 16, a cover 22 supported under each basin 16 for at least partially concealing plumbing (e.g., water supply, drain, etc.) associated with the station, a hand drying fixture (e.g., electric hand dryer, towel dispenser, etc.), shown as hand dryer 28, and an interface 65 for filling or refilling a reservoir (e.g., chamber, receptacle, etc.) that is configured to retain a liquid soap for soap dispenser 30.
The embodiment illustrated is further shown as including a waste receptacle 32 adjacent to the upper station 12 and a plurality of photovoltaic cells 34 mounted on a shelf or platform 36 located above the other components of the washing stations 12, 14. Waste receptacle 32 may be at any of a variety of locations on the lavatory system 10 (e.g., between each wash station, on the outer ends of the wash stations, etc.). According to the embodiment illustrated, faucet 20 and soap dispenser 30 are powered by the photovoltaic cells 34 and a power management system, such as disclosed in U.S. patent application Ser. No. 11/041,882 titled “Lavatory System” filed Jan. 21, 2005 (Attorney Docket No. 063359-0345), referenced above, the entire contents of which is hereby incorporated herein by reference in its entirety. Further, if hand dryer 28 is an electric hand dryer, hand dryer 28 may be powered by the same photovoltaic cells 34 and power management system.
A hand dryer 28 is provided at each washing station 12, 14 so that a user does not have to move away from the washing station before drying his or her hands. Having access to a hand dryer 28 at the washing station, as opposed to a distance away from the washing station, is intended to reduce the likelihood that water from a user's hands will collect on the floor of the facility in which the lavatory system is located. According to the embodiment illustrated, hand dryer 28 is integrated with a backsplash area 18 of the washing station and is supported by the countertop 41. As shown in
According to an exemplary embodiment, hand dryer 28 is an electric hand dryer configured to provide forced air in the direction of the user. The output opening of the hand dryer is configured so that as water is blown off the hands of a user, the water will be directed towards the basin. To facilitate this, the output opening of hand dryer 28 is directed downward and inward towards basin 16. To further facilitate the collection of the water in the basin rather than the floor, the top surface of countertop 41 may have a contour that is angled (e.g., slanted, sloped, etc.) downward and/or inward towards basin 16 as shown in

Such a system is intended to provide an accurate indication of the level of soap within the reservoir rather than simply providing an indication that the reservoir is either full or empty. Once all of the light bars are off, a user would know that it is time to refill the reservoir. For such an embodiment, a sensor and/or switch may be provided in the reservoir that provides an output signal representative of the soap level in the reservoir.
According to the various alternative embodiments, the illumination of the light bars may be reversed so that the light bars become illuminated as the reservoir becomes depleted of soap. Such a configuration may conserve power because the light bars would not have to be illuminated until the reservoir was close to being empty. According to further alternative embodiments, display 75 may be any type of device capable of providing an indication of the level of soap within the reservoir. For example, display 75 may be gauge having a pointer that moves between an area on the gauge marked “E” for empty and an area on the gauge marked “F” for full. Such a display may be an electronic and/or mechanical gauge. According to still further alternative embodiments, an audio indicator may be provided in addition to or in place of the visual indicator.

For example, the countertop may be made from any of a variety of solid surface materials, stainless steel, laminates, fiberglass, and the like. According to an exemplary embodiment, the countertop is made from a densified solid surface material composed of an acrylic modified polyester resin that complies with ANSI Z124.3 and Z124.6 as well as ANSI SS-1-2001, and/or other applicable regulations or standards. According to a particularly preferred embodiment, the surface material is of a type commercially available under the trade name TERREON.RTM. from Bradley Corporation of Menomonee Falls, Wis. The countertop is intended to be resistant to chemicals, stains, burns, and impact such that surface damage can easily be repaired with everyday cleaners or fine grit abrasives. According to a preferred embodiment, the countertop or deck is molded from a mixture of resin, filler, pigment, and initiator (catalyst), which forms a liquid when combined. Also, other molding operations may be used to form these components.
Also, the terms are intended to be broad terms and not terms of limitation. These components may be used with any of a variety of hand washing locations and are not intended to be limited to use with washroom or restroom applications. For purposes of this disclosure, the term “coupled” shall mean the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature. Such joining may also relate to mechanical, fluid, or electrical relationship between the two components.
It is also important to note that the construction and arrangement of the elements of the multi height lavatory system as shown in the preferred and other exemplary embodiments are illustrative only. Although only a few embodiments of the present invention have been described in detail in this disclosure, those skilled in the art who review this disclosure will readily appreciate that many modifications are possible (e.g., variations in sizes, dimensions, structures, shapes and proportions of the various elements, values of parameters, mounting arrangements, materials, colors, orientations, etc.) without materially departing from the novel teachings and advantages of the subject matter recited in the disclosed embodiments. For example, various embodiments are shown as two or three wash stations, but it should be understood that these are shown as examples and the invention is applicable to any of a variety of wash station configurations (e.g., one, two, three, four, etc. stations). Also, “ADA” standards for height of hand washing stations is provided by way of example, and is not intended to be limiting—any of a variety of heights may be used, (e.g., dictated by accessibility regulations or otherwise desired). Accordingly, all such modifications are intended to be included within the scope of the present invention as defined in the disclosed embodiments. The order or sequence of any process or method steps may be varied or re-sequenced according to alternative embodiments. In the disclosed embodiments, any means-plus-function clause is intended to cover the structures described herein as performing the recited function and not only structural equivalents but also equivalent structures. Other substitutions, modifications, changes and/or omissions may be made in the design, operating conditions and arrangement of the preferred and other exemplary embodiments without departing from the spirit of the present invention.
