Benefits of technology
The present invention is a retrofitted faucet control system that is mounted under the sink, on the wall, and directly under the existing faucet. It features two or more normally closed hydraulically operated valve input ports connected by way of two standard tubes to the water supply hot and cold valves. The valves output ports are then connected to the existing faucet and hand held sprayer. In addition, the manifold possess two additional in and out ports by means of two flexible tubes connected to a pilot valve or valves mounted behind the cabinet doorframe or toe kick area of the cabinet. To activate the system, a slight knee pressure on the cabinet doors or slight foot pressure on the pilot valve housing in the toe kick area of the cabinet is required to open the normally closed pilot valve, in turn causing the hydraulically operated valves to open allowing water to flow freely to the valve block output ports and through the existing faucet as its setting permits. The on-off control of water flow is accomplished by the normally closed push button pilot valves connected to the right, left, or both cabinet doorframes or in the toe kick area of the cabinet. The continuous water flow is accomplished by a push button latchable pilot valve connected to the right or left cabinet door. To latch the pilot valve, a slight knee pressure is applied to the left or right cabinet door. In latched mode, the hydraulically operated valve remains open indefinitely and the faucet works conventionally. The user can manipulate the water flow manually and conventionally or terminate the flow by applying a second knee pressure to the left cabinet door or by turning the faucet manually to the off position. The flexibility of this device also permits the use of other pilot valve mounting configurations and locations. To child proof the system, all that is necessary is to close the sink faucet manually. In this case, if a child exerts pressure on the cabinet door or toe kick valve, the valve block will open but the closed sink faucet restricts water flow.
Problems solved by technology
Unfortunately the electronic and foot pedal variation of faucet control valves have demonstrated many limitations and shortfalls, making the need for a more practical and user friendly device for households even more apparent.
The existing electronic version of the faucet control valve limits its use for simple hand washing applications.
It's indiscriminate actuation by sensing an object makes this type of valve faucet useless for any other application that requires instantaneous on / off control of water flow.
Other disadvantages of electronic faucets are the lack of control over the water flow and ability to override the system.
In case of power failure, these units can only rely on limited storage capacity of the battery cells.
Furthermore, because the components of electronic faucets are interdependent and inseparable, they replace the existing faucet without making any use of it.
Also because of extensive electronic circuitry and its related high cost, plus their functional limitation, the electronic faucets are most suitable only for newly built public hand washing facilities where high cost any limitations are not of any major concern.
Similarly, the floor mounted foot pedal is an obtrusive device, difficult to use and to install and requires extensive plumbing changes.
The foot pedals bulky space-taking body makes floor cleaning difficult and becomes an obstacle to foot traffic.
Its use by the elderly and some physically impaired individuals is also limited.
Due to extensive plumbing changes and its related high cost, foot pedal sink faucet controls are only suitable for institutional use.
The impracticality, inconvenience, difficulty of installation, and high cost of existing devices necessitates the need for a new device that is practical, responsive, easy to use, easy to install, and low cost.

Embodiment Construction
[0022]With reference to FIG. 1, a typical sink cabinet is shown in FIG. 1. Having bowl 1, faucet valve 2, 3 under the sink cabinet doors 4, 5, water supply valve gland nuts 6, 7, connecting tubes 8, 9 and upper door frame 10. In FIG. 1 it can be seen that, conventionally, the sink faucet valve 2, 3 are connected by means of tubes 8, 9 to the supply valve gland nuts 6, 7. FIG. 1 also shows the upper door frame 10 to which cabinet doors 4, 5 are rested upon while closed.
[0023]To install the present invention, the gland nuts 6, 7 are first removed as shown in FIG. 3. The valve body inlet ports 11, 12 are connected through supply tubes 15, 16 to the water supply valve gland nuts 6, 7. The faucet connecting tubes 8, 9 are then connected to the valve body outlet ports 13, 14 of valve manifold 17. The controlling pilot valve which take the form of latching pilot valve 21 and a momentarily pilot valve 22 are then fastened to the upper door frame 10 in the manner shown in FIG. 2 and FIG. 4. ...

A manifold containing a set of hydraulically operated valves, interposed between a water supply line and an existing faucet and actuated by one or more pilot valves mounted on the sink cabinet door frame or in toe kick area of a cabinet, will provide instantaneous control of water flow from an existing sink faucet. The controlling pilot valves are easily mounted on the cabinet door frame or in the form of pressure sensitive valves mounted to the toe kick area of the cabinet. Slight knee pressure on the door or a gentle toe pressure on these controlling pilot valves opens the valves manifold and water flow through the faucet.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to sink faucets and more specifically to an automatic valve control system for remotely activating a water faucet.[0003]2. Description of Related Art[0004]Remote and automatic control of a sink faucet goes back many years. In early years the use of photo cells and foot pedal were common and more recently the use of electronic proximity switches has become wide spread. The introduction of numerous electronic controlled faucets in recent years points to the need for a functionally multipurpose remote and automatic sink faucet control system. Besides the protection from transfer of bacteria and the convenience of hand free operation, the water saving potential and capability of a reliable, low maintenance, functional system will make such a device a necessity rather than a luxury.[0005]Unfortunately the electronic and foot pedal variation of faucet control valves have demonstrated ma...
