The stepped portion 114 includes a portion that abuts the vertical portion 30 and includes the plurality of openings 46 that align with the openings 42 in the vertical portion 30 to receive the fasteners 60, and a portion that is received in the opening 40 in the vertical portion 30. The main body 110 may include at least a portion 120 at the front of the main body 110 that is transparent or is otherwise attached to a transparent portion to allow for the level of fluid to be visually determined. The main body 110 may also include indicia on the transparent portion 120, such as indicia 122 indicating a maximum fill line and indicia 124 indicating that the fluid level should be refilled. The indicia 122 and 124 may be molded onto the portion 120 or incorporated in other suitable manner.

The cover 102 abuts the top of the reservoir 100 and includes an opening 130 for receiving the flap 104 and the plurality of openings 48 that align with the openings 44 in the vertical portion 30 to receive the fasteners 62. The flap 104 may be pivotally coupled to the cover 102 at the opening 130 in any suitable manner, such as by pins 132 received in openings 134 at opposite sides of the flap 104 that are also received in corresponding openings 136 in the cover 102 and held by suitable retainers 138. The flap 104 is pivotable relative to the cover 102 to enable refilling of the reservoir 100 without removal of the dispenser 10 from the mounting bracket 80.

Referring additionally to FIG. 7, the tube assembly 106 includes a tube 140 having an inlet 142 and outlet 144, a first valve 146 at the inlet 142 of the tube 140, and a second valve 148 at the outlet 144 of the tube 140. The tube assembly 106 may be coupled to the outlet port 118 of the reservoir 100 in any suitable manner, for example by threads 150 on an outer surface of the outlet port 118 that mate with threads 152 on an inner surface of the tube 140 at the inlet 142. The tube 140 extends into the motor housing 18 and the outlet 144 of the tube 140 extends through an opening 154 at a bottom of the motor housing 18 to deliver fluid into the area 36 that receives the user's hands. It will be appreciated that the tube may have any suitable cross-sectional shape.

The first valve 146 includes a closing member or ball 156 that is in a first or open position against a ledge in the tube 140 away from the inlet 142 allowing fluid from the reservoir 100 to enter to tube 140, and that is movable to a second or closed position as shown in FIG. 7 closing the inlet 142 when the tube 140 is deflected as described below. In the second position, the ball 156 prevents fluid in the reservoir 100 from entering the tube 140 as fluid is being dispensed. The second valve 148 includes a valve body 158 having an inlet 160, a closing member or poppet 162 biased against the inlet 160, an outlet 164, and a resilient member 166, such as a spring, that biases the poppet 162 against the inlet 160 to prevent fluid from exiting the tube 140 when a user's hands have not been detected. The poppet 160 is movable from a first or closed position shown in FIG. 7 to a second or open position away from the inlet 160 allowing fluid to flow through the inlet 160 to the outlet 164 and out of the outlet 144 of the tube assembly 106 when the tube 140 is deflected.

Turning now to the cover 22 in detail, the cover 22 is designed to surround the reservoir 100 and overlap a portion of the motor housing 18.

The indication display is configured to be received in the recessed area 174 to be flush with the cover 22, and can include suitable icons 182 and 184, such as a water drop with a transmission symbol below it and a battery symbol. When a user's hand is detected, the icon 182 may light up or flash to provide a visual indication that the dispenser 10 has been activated. The icon 182 may also light up or flash periodically when no activation has been detected to indicate the dispenser 10 is operational, for example by flashing a light every 5 seconds.

The battery icon 184 may be lit up flash a first color, such as green, to indicate there is sufficient battery, and may be lit up or flash a second color, such as orange, to indicate the battery is low. Alternatively, the battery icon 184 may only light up or flash once the battery has reached a low power level. In either embodiment, the battery icon 184 may light up or flash to indicate low battery a predetermined number of activations before the battery can no longer operate the dispenser 10. For example, the batter icon 184 may flash orange when the battery is low to indicate there are fifty activations left before the battery can no longer operate the dispenser 10. In an embodiment, the indication display 176 can be a capacitive sensor providing an alternative method of activating the dispenser.

Turning additionally to FIGS. 8-11 the motor housing 18 will be described in detail. The motor housing 18 includes a wall 190 with a curved front and a bottom portion 192 that defines with the wall 190 a cavity 194. The wall 190 includes a recessed area 196 having the opening 180, projections 198 on the sides of the wall 190 serving as grip areas for the user, and the openings 52 that align with the openings 50 in the vertical portion 30 to receive the fasteners 64. The bottom portion 192 includes a plurality of openings through which various components extend. For example, the bottom portion 192 includes the opening 154 through which the outlet 144 of the tube 140 extends, an opening 200 rearward of the opening 154 through which one or more sensors 202, such as an IR sensor extends, and an opening 204 at a rear of the bottom portion 192 through which a switch 206 of a main power switch 208 extends.

Turning additionally to FIGS. 12 and 13, a control assembly 210 will be described in detail. The control assembly 210 includes a control board 212, such as a printed circuit board assembly (PCBA), a motor assembly 214, the one or more sensor 202, and the main power switch 208. The control board 212 is coupled to the bottom portion 192 of the motor housing 18 in a suitable manner, such as by fasteners 216 surrounded by washers 218 that are received in corresponding openings 220 in the control board 212, and coupled to the battery in a suitable manner, such as by a wired connection. Coupled to the bottom of the control board 212 are the one or more sensors 202, and coupled to the rear of the control board 212 is the main power switch 208. The one or more sensors 202 and the main power switch 208 may be communicatively coupled to the control board 212 in any suitable manner, such as a direct connection, a wired connection, etc. The one or more sensors 202 may be coupled to the motor housing 18 and/or the control board 212 in any suitable manner, such as by adhesive, fasteners, etc., and the main power switch 208 may be coupled to the motor housing 18 and/or the control board 212 in any suitable manner, such as by adhesive, fasteners 222, etc. The main power switch is positioned at a rear of the assembly to prevent inadvertent activation/deactivation of the dispenser.

Turning now to the motor assembly 214, the motor assembly 214 includes a bracket 230, a motor 232 connected to the control board 212 via a connector 234, a cam switch 236 connected to the control board 212 via a connector 238, a bracket switch 240, a cam 242, an actuator 244, an actuator bracket assembly 246, and a bracket switch actuator 228. The bracket 230 may be coupled to the bottom portion 192 of the motor housing 18 in any suitable manner, such as by fasteners 248 surrounded by washers 250 that are received in openings 252 in the bracket 230 that align with corresponding openings in the bottom portion 192 of the motor housing 18. The bracket 230 can be positioned above the control board 212 toward a side of the control board 212, and the bracket 230 may include a plurality of openings for various components of the motor assembly 214. For example, the bracket 230 may include a plurality of openings 254 that may receive fasteners 256 that are received in corresponding openings 258 in the motor 232 to connect the motor 232 to the bracket 230. The bracket 230 may also include an opening 260 through which a shaft 262 of the motor 232 extends, and a plurality of openings 264 that align with corresponding openings 266 in the bracket switch 240 to receive fasteners 268 that are surrounded by washers 270. It will be appreciated that the shaft 262 may extend from the motor 232 or be otherwise connected to a shaft of the motor 232 in a suitable manner.

The bracket switch 240 may also include openings 280 that align with openings 282 in the cam switch 236 and openings 284 in the bracket switch actuator 228 to receive fasteners 286 that are surrounded by washers 288. The fasteners 286 are received in corresponding washers 290 and nuts 292 abutting the bracket switch 240. The cam 242 abuts the bracket 230 and bracket switch 240 and is attached to the shaft 262 of the motor 232 to be driven by the motor, for example by a set screw 294.

The actuator 244 includes a body 300, a hammer portion 302 at an end of the body 300 for compressing the tube 140 to deliver fluid to the user, and a slot 304 at the other end of the body 300. A projection 306 extending from the cam 242 is received in the slot 304 to drive the actuator 244 toward and away from the tube 140. The actuator 244 is held in position by the actuator bracket assembly 246, which includes a first portion 308 with a projection 310 and openings 312 on opposite sides of the projection 310, and a second portion 314 with a channel 316 and openings 318 on opposite sides of the channel 316. The openings 312 are aligned with the openings 318 to receive fasteners 320, and the projection 310 is received in the channel 316 along with the body 300 of the actuator 244 to hold the actuator 244 in position and allow it to move horizontally toward and away from the tube 140.

To install the dispenser 10, for example in the lavatory of the aircraft, the mounting bracket 80 is attached to either a wall or a counter in the lavatory via suitable fasteners received in the openings 94. If the dispenser 10 is being vertically mounted, the openings 82 are aligned with the lock pins 86 and the dispenser 10 is advanced towards the mounting bracket 80 until the lock pins 86 extend through the first portion of the openings 82. The dispenser 10 is then rotated relative to the mounting bracket 80 to move the lock pins 86 into the second portion of the openings 82 to secure the dispenser to the mounting bracket 80 and thus the wall of the lavatory. Similarly, if the dispenser 10 is being horizontally mounted, the openings 84 are aligned with the lock pins 86 and the dispenser 10 is advanced towards the mounting bracket 80 until the lock pins 86 extend through the first portion of the openings 84. The dispenser 10 is then rotated relative to the mounting bracket 80 to move the lock pins 86 into the second portion of the openings 84 to secure the dispenser to the mounting bracket 80 and thus the counter of the lavatory.

To operate the dispenser 10, the switch 206 is moved from an OFF position to an ON position. Once the dispenser is on, the icon 182 may be configured to flash to provide a visual indication to the user that the dispenser is active. When a user positions her hands in the area 36, the user's hands move below the outlet 144 before the sensor 202 is activated due to the outlet being positioned forward of the sensor. Once a portion of the user's hands are below the sensor 202, another portion of the user's hands, for example the user's palm, is positioned below the outlet 144.

When the sensor 202 detects the presence of the user's hands, the presence is communicated to the motor assembly 214. In an embodiment, the icon 182 may light up or flash to indicate to the user that the dispenser 10 has been activated. The motor 232 is thereby activated for one cycle, for example to effect one revolution of the cam 242. The motor 232 rotates effecting movement of the cam 242, which rotates to move the projection 306 within the slot 304 to move the actuator 244 from a first position to a second position. The cam 242 can complete one revolution whereby it contacts the bracket switch activator 228 causing the cam switch 236 to communicate to the control board 212 to turn off the motor 232. In the second position, the hammer portion 302 of the actuator 244 contacts the tube 140. The force of the hammer portion 302 against the tube 140 causes the biasing force of the spring 166 to be overcome and the poppet 162 to move from the first position to the second position, thereby allowing the fluid to flow from the tube 140 through the inlet 160 of the valve 148 to the outlet 164 and out of the outlet 144 of the tube assembly 106 into the user's hands. The force of the hammer portion 302 against the tube 140 also causes the ball 156 to move from the first position to the second position closing the inlet 142 of the tube assembly 106 to prevent fluid from the reservoir 100 from entering the tube 140 as fluid is being dispensed from the outlet 144.

The electronics have logic configured to provide one activation regardless of the amount of time the user's hands or other object are under the sensor 202. This prevents the reservoir 100 from being drained if an object is advertently left below the sensor 202. If the user desires more fluid, the user first removes her hands from below the sensor 202 and then repositions her hands below the sensor 202.
