The present invention relates generally to a mount for mounting a device, such as a faucet controller to a sink or basin and a valve actuator operable with a body part or limb.
It has been amply demonstrated by a variety of studies and research that conventional hand operated faucets are a source of wasted water and energy and a cross contamination point for the spread of infectious diseases. Several devices have been developed and marketed to overcome these problems but all have some disadvantages. Mechanical foot pedal or knee operated faucets are expensive and often require extensive and costly modifications to plumbing and cabinetry. Infra-red sensor electrically operated faucets are costly to install, require an electrical outlet, may be erratic in operation and may permit cold and hot water cross flow. Foot pedal valves controlling the application of air pressure to water controlling valves are expensive and often difficult to install and require a compressed air source. Of these, ultrasound sensor electrically operated valves require batteries and are too bulky to comfortably adapt to many faucets. Other types operate by a foot control supplying fluid pressure through flexible tubing connected to a spout mounted valve. These tend to be untidy and cumbersome to operate. Examples of such devices are described and illustrated in U.S. Pat. No. 5,029,806, dated Jul. 9, 1991 granted to Chaung for a “Foot-Controlled Valve” and in U.S. Pat. No. 3,536,294, dated Oct. 27, 1970, granted to Rodrigues for a “Foot-Operated Control Valve Attachment Device for Water Faucets.”
Faucet controllers may include a metering feature, which typically includes an orifice which is subject to plugging and mineralization or a reservoir which is bulky and subject to plugging, mineralization, and leakage.
U.S. Pat. No. 5,505,227 granted to Pubben, discloses a “hands free” system for controlling the flow of water to a faucet. The system includes a pilot valve which provides pilot water of controlled pressure to operate diaphragm valves in a control block. The valves in the control block may be respectively connected between hot and cold water supply lines and a faucet. The pilot valve may be located in a position where it can be operated by a user's knee or elbow, or in another location where foot operation is possible.
There are a wide variety of configurations for the design and installation of sinks or basins, known to one who is ordinarily skilled in the art. Three common configurations include “wall-mount”, “counter-mount”, and “carrier arm mount”.
In a wall-mount or wall-hung configuration, the sink or basin is mounted to the wall and extends outward from the wall in a cantilever fashion. Optionally, legs or other supports may provide additional support to the free end. This configuration is very common for public spaces such as restrooms, industrial buildings, and for health related facilities such as hospitals and other medical facilities.
In a counter-mount configuration, a counter support is provided with a cut-out to suit the sink and basin, and the sink or basin is dropped in (drop-in counter-mount) or supported beneath the counter (under counter-mount). This configuration is very common for public spaces such as restrooms in commercial buildings and shopping malls.
In a carrier arm mount, a fixture carrier is utilized to support the sink or basin. The fixture carrier is mounted to the floor and/or wall behind the sink or basin and carrier arms extend in a cantilever fashion from the fixture carrier to support the sink or basin, generally with as little of the carrier arms visible as possible. The sink or basin is attached to the carrier arms by openings in the underside of the sink or basin, commonly referred to as carrier arm mounting holes, or hidden carrier arm holes.
It is, therefore, desirable to provide a mount for a device, for example an actuator that is adaptable to a number of different configurations. It is, therefore, desirable to have a simple valve actuator operable by either hip, arm, elbow, foot or knee etc. and easily installed in association with a sink or basin having carrier arm mounting holes.
It is an object of the present invention to obviate or mitigate at least one disadvantage of previous knee/thigh actuator mounts and valve actuator assemblies. It is an object of the present invention to obviate or mitigate at least one disadvantage of previous faucet controller assemblies.
In a first aspect, the invention provides a mount for mounting a device to a sink or basin having carrier arm mounting holes, the mount having a universal arm adapted to fixedly connect with the device, and a fastener adapted to fixedly mount the universal arm to at least one of the carrier arm mounting holes. Preferably, the device is a faucet controller or a pilot valve.
In a further aspect, the invention provides a valve actuator assembly for operating a valve for a sink or basin and operable with a push pad, the valve actuator assembly having a housing mountable to the sink or basin, the housing supporting a shaft and a valve, the shaft rotatable between a normal at rest position and a valve operating position, a a rocker operably connected with a shaft, for rotation with the shaft, the rocker having an extent for operably urging a member supporting the valve when the shaft in is the valve operating position, and a push pad mechanism operably connected with the shaft and the push pad, wherein the push pad is adapted to move the shaft between the normal at rest position and the valve operating position to selectively activate the valve.
In a further aspect, the invention provides a method of mounting a device to a sink or basin by locating at least one hole in the underside of the sink or basin, inserting a fastener into the hole, activating the fastener to lock the fastener in the hole, and mounting a device to the sink or basin by attachment to the fastener. Preferably the device is a faucet controller or a pilot valve. Preferably, the hole is a carrier arm mounting hole.
In a further aspect, the present invention provides a faucet controller for operating a valve mounted in association with a sink or basin, having a carrier arm mounting hole having a mounting means for mounting the valve to carrier arm mounting hole, a joystick actuator mountable on the valve for movement between a normal at rest position and a valve operating position, and a member connected with the joystick for forcing the joystick actuator into the valve operating position.

The sink or basin end 50 includes a flexible, swivel, or gimbaled connection in the form of a ball joint 70. The ball joint 70 includes a half sphere plinth 75 fixedly attachable to the carrier arm mounting hole 20 by fastener 35 in the form of a bar 80. A centralizer 79 may be matched to the size of the carrier arm mounting holes 20. A cup 90 is formed into the universal arm 40. The ball joint 70 is completed by a cover cap 100 and is fixed in place by a fastener in the form of a screw 110.
Fastener 35 in the form of bar 80 in conjunction with the screw 110 is used to fasten the universal arm 40 to the carrier arm mounting holes 20 of the sink or basin 30 (
As shown, the fastener 35 in the form of a bar 80 is more suitable to the ceramic (porcelain) type sink or basin having an outer wall, an inner wall, and void between the outer and inner wall, the carrier arm mounting holes 20 providing the ability to place the bar 80 in the void and then be tightened against the outer wall by the screw 110 to fasten the universal arm 40 to the sink or basin 30. Other sink or basin 30 designs or constructions may provide cylindrical carrier arm mounting holes 20, for which other fasteners, known to one skilled in the art may be more suitable, for example expansion anchors.
A compressible washer 77, for example a rubber or acetyl washer, fits between the half sphere plinth 75 and the sink or basin 30 (
The centralizer 79 may be of such a height (relative to the half sphere plinth 75 and in relation to the outer wall thickness of the sink or basin 30) that when the bar 80 is tightened by screw 110, the bar 80 rests upon the centralizer 79 to limit the amount of force the bar 80 imparts upon the sink or basin 30.
The valve actuator assembly end 60 of the universal arm 40 includes connection means for connecting the valve actuator assembly 1000 (
It is recognized by one ordinarily skilled in the art that, while the ball joint 70 and the universal arm 40 provide a degree of adjustability or universality, the present invention may be embodied in configurations lacking these features. For example, a variant of the valve actuator assembly 1000 could connect directly to the sink or basin 30 provided the valve actuator assembly 1000 included extended arms which correspond to the sink or basin 30 to position the fastener 35 in a position to mate with at least one carrier arm mounting hole 20.

While shown as a relatively straight, elastic member, the whisker 140 may function in a wide variety of configurations, shapes and sizes. For example, but not limited to, a beaver tail, paddle, arm, cylinder, cone, curved, spiral, sinusoidal, zigzag etc. and may be long, short, slender, narrow, wide etc.
Depending on the material or combination of materials chosen, the whisker 140 may end up being very slender, for example if constructed out of straight spring steel. In such cases, and optional guard (not shown) in the form of an enlarged sphere or disk may be added to the end of the whisker 140 to improve visibility and improve ergonomics.
The whisker 140 may be identified by color to designate the fluid delivered by the faucet (not shown) being controlled by the faucet controller 10, for example red for hot, blue for cold, red and blue for mix, or otherwise marked. The whisker 140 may be made in a variety of configurations. Preferably, as shown in
Referring to 6a a faucet controller is mounted directly to at least one carrier arm mounting hole 20. Referring to

This configuration provides a very adjustable, yet very solid mounting of the valve actuator assembly 1000 to the sink or basin 30. The valve actuator assembly 1000 is operable by a push pad 1020, movable between a normal at rest position and a valve operating position, and movable between the valve operating position and an overtravel position. A housing 1025 contains and generally conceals the inner workings.

In the preferred embodiment, the rocker 1030 is rotatably movable relative to the shaft 1035 and held in place by bias means in the form of a torsion spring 1060 and a snap in bushing (not shown). The torsion spring 1060 allows the push pad 1020 (and the corresponding shaft 1035) to move between the valve operating position and the overtravel position while allowing the rocker 1030 to remain in the valve actuation position, reducing the forces applied to the valve 1040 when the push pad 1020 is pushed into the overtravel position and provides additional bias to return the shaft 1035 (and the corresponding push pad 1020) to the valve operating position. A hard stop (not) shown may be incorporated into the valve actuator mechanism 1000 or the push pad 1020 may be come into contact the underside of the sink or basin 30 at an extreme overtravel position.
In the preferred embodiment, damping means in the form of damper 1070, for example a rotary dashpot or viscous fluid damper may be operably connected with the shaft 1035, thereby damping the movement of the shaft 1035 (and the associated push pad 1020).
The valve actuator assembly 1000 may include a metering feature by selecting the spring rates of the torsion spring 1050 and/or torsion spring 1060 and the damping rate of the damper 1070 to produce a desired time meter. When a user pushes the push pad 1020 it is biased to return to the normal at rest position, but that return motion may be damped, thus providing a metering effect. The metering feature may be user controllable or selectable, such that a greater push of the push pad 1020 produces a greater metered time than that of a lesser push, providing the user a simple but effective means of handsfree metering faucet.
A metering feature is particularly advantageous to knee/thigh type actuators, in that it allows the user to activate (and then release) the push pad 1020 and then perform a task while the water continues to flow, for example leaning over the sink or basin to wash their face or obtaining some equipment or material from a laboratory bench for rinsing, without having to maintain pressure on the push pad 1020 with their knee or thigh.
The metering feature of the present invention is free from the mineralization, plugging, and bulkiness of orifice and reservoir type metering systems.
The torsion springs may be linear or non-linear. The damper 1070 may be linear or non-linear.

In a variant of the present invention, the universal mounting arms 40 (and the associated fastener 35) may be used to mount other types, configurations and designs of valve actuator assemblies, for example knee action stirrup handles or foot pedals to fixtures, such as the sink or basin 30, and may be used to mount other devices, equipment, controls, or accessories to fixtures, such as the sink or basin 30.

The faucet controller 5 (or a plurality of the faucet controllers 5) may be installed in a variety of configurations, elevations, orientations, etc. For example, but not limited to, installations suitable for operation of the faucet controller 5 by activation by a user's finger, hand, arm, elbow, shoulder, hip, leg, knee, calf, foot, toe etc.
In operation, a device such as a faucet controller 5 is selectively mounted directly or indirectly to a carrier arm mounting hole 20 by fastener 35.
In operation, application of pressure to the whisker 140 via a user's finger, hand, arm, elbow, shoulder, hip, leg, knee, calf, foot, toe etc. or other means causes movement of the joystick 350, thus causing pivotal movement of the disc 410 within the disk housing 430 to depress the valve piston 420, causing the valve 400 to move between a normal at rest position and a valve operating position. Release of the pressure on the whisker 140 allows the joystick 350 of the valve 400 to return to the normal at rest position.
The whisker 140 may be removable from the joystick 350 (and/or may be user replaceable).
