Abstract:
A device that fits between a shower neck service pipe and a shower head. The water flowing through this device is controlled to provide a full-flow of water for a predetermined time frame. Once this time frame has expired, the device cuts off the flow of water by a substantial amount. This greatly reduced flow of water provides for less stimulation and enjoyment of showering and hastens the departure of the bather as well as conserves water and the energy needed to heat that water.

     FIELD OF INVENTION 
       [0004]    The present invention relates to controlling shower times and, more particularly, to limiting shower times through the means of a device attached to the shower head that is operated by a low voltage battery which device provides for a full flow of water for a preset time frame followed by a reduced flow of water. 
       BACKGROUND OF THE INVENTION 
       [0005]    Parents with teenage children have fought the battle for years of getting their kids out of the shower in a reasonable time frame. Many parents are “sick and tired” of their kids being late for the dinner table, late for the school bus, late for the carpool, late for soccer practice, or just being late for life. In many households, this battle of excessive showering times is a frequent event occurring daily if not multiple times during the day. Additionally, extended showering typically depletes hot water reserves and leaves the next person in line with a short or cold water shower. With the cost of natural gas and electric usage rates continuing to climb upward, extended showering has hit hard the budgets of households, dormitories, rental units, subsidized housings, locker rooms, etc., etc. In other areas of drought imposed water restrictions with surcharges or low producing domestic water wells, uncontrolled water usage can have a devastating effect on the availability and water reserves. Showering has long been recognized as one of the largest water users (and wasters) of domestic households. 
         [0006]    There have been a number of solutions available over the years. Some practical and inexpensive, others more costly and somewhat effective, but few, if any, are reliable on a day-in/day-out basis over the long haul. 
         [0007]    Some water districts in this country offer at low costs a 5-minute hour glass timer that attaches through suction to a shower wall. The intended purpose is to let the bather know when 5-minutes is up and time and voluntary vacate the shower. The intent is good, but few teenagers (and many adults for that matter) will continue with their normal showering habits as there is no force to get them to finish showering. Another approach is to place a restrictor orifice in the showerhead inlet thus limiting the amount of shower water used by bathers. Again, the potential benefit from using less water is inherent in this device, but if the bather continues to shower without either a forced or voluntary time limitation, the end results can be marginal. Many women don&#39;t like these devices, as well, as the restricted water flow does little to rinse out shampoo from a full head of hair. 
         [0008]    Other devices like the Water Saving Shower (U.S. Pat. No. 6,016,836) and Timed Shower Valve Manager (U.S. Pat. No. 6,899,133) offer a non-voluntary approach to limiting shower times, but fall short in reliability as the wide range and variance (while using) of water pressure within a household cause these units, which control water delivery with solenoids, to frequently malfunction. Additional problems with these devices is that they are too easy to remove (teenager looking to extend showering time), do not cut the water flow enough to encourage cessation of showering, and the absence of visual or audible notification when the reset or restricted water flow time frame has expired. Another unit does limit shower times, but its unruly size (large as a parking meter) requires extensive retrofitting (inside the wall between the studs) and extension of a 110 volt electric line feed. The high cost of installation and the high initial cost of the unit make this an expensive and unpractical solution to showering water conservation and control. 
         [0009]    The shortcomings of prior art have left a void for the need of an ineffective, reliable, and non-voluntary device that controls showering times. The need to limit showering times to help eliminate family feuds, the need to limit showering times to conserve water and the energy needed to heat that water, and the need to provide a fail-safe device with low operating costs is long overdue. To gain wide spread acceptance this device needs to be easy to install, easy to use, offer flexible time frames, difficult to disable or override, and pay for itself with water and energy savings within a short time frame, i.e., 12 months or less. 
       SUMMARY OF THE INVENTION 
       [0010]    In accordance with the present invention, there is provided . . . a device that fits between a shower neck service pope and a shower head. The water flowing through this device is controlled to provide a full-flow of water for a predetermined time frame. Once this time frame has expired, the device cuts off the flow of water by approximately 70%. This greatly reduced flow of water provides for less stimulation and enjoyment of showering and hastens the departure of the bather.

A battery cover access panel  1 , an electrical wire  2  connecting a battery  16  to a circuit board  4 , a magnetic sensor  3 , an alarm  5 , an electric motor wire  6  connecting an electrical motor  19  of  FIG. 2  and the circuit board  4  of  FIG. 1 . Also on  FIG. 1  a flow-out tube  7 , a cam  9  positioned on a drive shaft  11 , a piston  12  with one end seated against the cam  9  and the other end inserted into a bypass bracket  23  of  FIG. 3 , a concave shaped bypass channel retainer washer  24  of  FIG. 3  and seated against a bypass channel seal  25  of  FIG. 3 . On  FIG. 1  a flow in tube  13 , a main flow channel  14 , an sensor wire  15  connection from the circuit board  4  to a sensor  26  of  FIG. 3 , a small gear  18  of  FIG. 2  positioned on the shaft of the electric motor  19  of  FIG. 2 . 
         [0014]      FIG. 2  provides a perspective view of the SHOWER &#39;N TIME with the front cover  8  removed. Elements include an electric motor  19 , a large gear  17  positioned on the drive shaft  11 , a small gear  18  positioned on the electric motor  19  shaft, a sensory bracket  20 , and a battery retainer  21 . 
         [0015]      FIG. 3  provides a side internal perspective and identifies the following elements. The bypass channel  22 , the bypass bracket  23 , the bypass channel retainer washer  24 , the bypass channel seal  25 , a sensor switch  26 , the sensor retainer  27 , sensory retainer ring, a sensor seal  29 , a magnet  30 , a warning lamp  31 , a washer  32 , and a set screw  33 . 
         [0016]    The purpose of the SHOWER &#39;N TIME is to provide for a full-water flow shower for a predetermined time frame, and once this full-flow time frame expires, cut the full-flow of water significantly or by approximately 70%. The reduced water flow provides for water conservation and a less stimulating water flow to continue showering. Warnings of changes in water flow and a reset interval are built in. 
       Operation 
       [0017]    The SHOWER &#39;N TIME is connected to a shower delivery pipe that comes out of the shower wall/ceiling with the flow-in tube  13  and connects with a showerhead device with the flow-out tube  7 . 
         [0018]    As a main control valve to a shower is turned on, water begins to flow into the shower delivery pipe and into a SHOWER &#39;N TIME unit through the flow-in tube  13 , and water continues to flow through the main flow channel  14  and out the flow-out tube  7 . As water volume builds in the main flow channel  14 , water pressure presses against the sensory seal  29  which closes the sensory switch  26 , which, in turn, signals through sensory wire  15  the control board  4 . The control board  4 , in turn, sends an electrical current, through the electric motor wire  6 , to the electric motor  19 . The electrical current to the electric motor  19  is momentary in nature, just long enough to rotate the small gear  18  which is engaged to the large gear  17 . The large gear  17  rotates the cam  9  on the drive shaft  11 . The rotating cam  9  releases pressure on the piston  12 , which is housed by the bypass bracket  23  and the bypass channel retainer washer  24 , and was seated against the bypass channel seal  25  which blocked water from passing through the bypass channel  22 . As the piston  12  retreats, the bypass channel seal  25  is restricted by the concave shape of the bypass channel retainer washer  24 . Water now flows through the main flow channel  14  and the bypass channel  22  and exits out the flow out tube  7 . The unit is now in full-flow water mode. At the same time a full-flow cycle timer starts in the circuit board. 
         [0019]    As the unit approaches the end of the full-flow cycle, the timer sends a signal on the circuit board  4  to the alarm  5 , also housed on the circuit board  4 . The alarm  5  provides an audible tone letting the bather know the full-flow mode is about to end and the unit will advance into restricted water flow mode. Once the full-flow time expires the control board  4  outputs an electrical current through the electrical motor wire  6  to the electric motor  19 . This momentary electrical current, however, to the electric motor  19  is of reversed polarity. This reversed electrical current rotates the small gear  18 , the large gear  17 , and the cam  9  in the opposite direction. This time the cam  9  forces the piston  12  to press firmly against the bypass channel seal  25  thus closing off the bypass channel  22 . Water now flows through the main flow channel  14  only, which is approximately 30% of full-flow mode. The unit is now in restricted or conservation flow mode. 
         [0020]    When the water is turned off at the main control valve for the shower, the water pressure in the main flow channel  14  drops and the input signal to the sensory switch  26  is lost. As soon as the control board  4  losses the input signal from the sensory switch  26 , a delay timer (let&#39;s say 5 minutes) on the control board  4  is started. During this delay or reset interval, the unit is restricted from providing full-flow water delivery. Concurrent with the reset interval, a warning lamp  31 , located on the control board  4 , is turned on. The lighted warning lamp  31  gives notice to a bather the unit is in restricted mode and cannot provide a full-flow of water until the reset time interval has expired, at which time the warning lamp  31  will go off. 
         [0021]    The restricted flow is the feature of the SHOWER &#39;N TIME that forces water conservation (including the heated water) and prompts the shower taker to finish showering as this restricted flow offers less than ideal showering conditions. 
         [0022]    Programming the unit. Setting of the full-flow water time frame is accomplished by placing the magnet  30  over the indicated target zone just above the magnetic sensory  3  on the control board  4  while the unit is not in use. The unit will give an audible tone or string of tones from the alarm  5 . The tone(s) corresponds to a time interval for a full-flow shower, i.e., 1 tone, 5 minutes; 2 tones 8 minutes, 3 tones 11 minutes, etc. The tones recycle once the program reaches the end of full-flow time settings. To set a full-flow time frame, the magnet  30  is held over the magnetic sensory  3  for the desired time that corresponds to the number of tones and then is removed. To verify the program setting, wait a few seconds and momentarily hold the magnet  30  over the magnetic sensor  3 . The alarm  5  will beep the setting programmed. The device will retain the setting programmed until the setting is changed or until the battery is changed. 
         [0023]    To help minimize the attempts of bathers removing the unit to avoid restricted or controlled showering, a set screw  33  is threaded into the wall of the flow-in tube  13 . Tightening this set screw  33  firmly positions the device on the shower delivery pipe thus making it resistant to removal. To help prevent excessive torque on the threads of the flow-in tube  13 , a washer  32  is inserted into the threaded area of the flow-in tube  13 . This washer  32  provides a water tight seal as well as stop when the unit is threaded onto a shower service pipe, thus eliminating the excessive pressures on the flow-in tube  13  caused by torque when the unit is threaded onto a shower service pipe. 
         [0024]    An important safety feature inherent in the operation of this unit is that the Shower Manager does not function as the main on/off water valve for the shower. Control of this important function, as well the mixture of hot/cold water, remains with the main shower valve installed on the shower. Also, the low-voltage battery  16  minimizes any electrical shock or hazard. Changing the battery is easily accomplished by accessing the battery  16  through the battery access panel  1 . When the battery  16  runs low, the unit stays in the conservation or restricted flow mode until the battery  16  is replaced. Controls and settings are preset at the time of installation giving the unit a fully automated operation. 
       CONCLUSION, RAMIFICATION AND SCOPE 
       [0025]    The reader will see that the SHOWER &#39;N TIME is a practical, safe, updated and non-voluntary alternative to the prior art and appeases the agendas of parents, property managers, water districts, conservationists, etc. 
         [0026]    While the SHOWER &#39;N TIME has been described with reference to particular embodiments, it is not intended to illustrate or describe all of the equivalent forms or ramification. Also, words used are words of description rather than limitation and various changes may be made without departing from the scope of the SHOWER &#39;N TIME.
