DETAILED DESCRIPTION OF THE DRAWINGS

(9) The embodiments of the invention described herein are not intended to be exhaustive or to limit the invention to the precise forms disclosed. Rather, the embodiments selected for description have been chosen to enable one skilled in the art to practice the invention.

(10) Referring initially to FIG. 1, an exemplary faucet 100 is shown mounted to a sink basin 200, and fluidly connected to a fluid source (illustratively, a hot water source 202 and a cold water source 204) which directs fluid through a conventional mixing valve 113 in order to adjust the temperature and the flow rate of the fluid. In the illustrated embodiment, the faucet 100 comprises a base 110 which is mounted to the sink basin 200 and includes an interior 111, a handle 112, and a hub 114. Hub 114 is pivotally coupled to base 110 such that hub 114 can rotate about longitudinal axis 300. In the illustrated embodiment, handle 112 is a lever coupled to mixing valve 113 and can be positioned at varying angles away from the base 110 to regulate fluid flow through the faucet 100. Furthermore, handle 112 can be rotated towards or away from the user to adjust the temperature of the fluid. In other embodiments, other handle configurations may be used to control the flow rate and temperature of fluid through the faucet 100.

(11) Referring to FIGS. 1, 2, and 4, faucet 100 further comprises a flexible waterway 120 which fluidly couples mixing valve 113 to a sprayer assembly or sprayhead 122 defining a fluid outlet 126 (FIG. 3). In the illustrated embodiment, flexible waterway 120 passes at least partially through, and is slidably received within, the interior 111 of the base 110 and extends vertically upward from the base 110 parallel to longitudinal axis 300 (FIG. 2). Flexible waterway 120 may bend, stretch, compress, or otherwise flex so that the user may move the fluid outlet 126 relative to the base 110. Flexible waterway 120 may be composed of rubber, plastic, or any other flexible material suitable for fluid flow and may also be coated in a waterproof coating. A hose weight 130 may be coupled to the waterway 120 below the sink basin 200.

(12) With reference to FIG. 2, faucet 100 further comprises an arm 140 extending between a first end 142 and a second end 146, and is positioned below an upper portion of the waterway 120. First end 142 of arm 140 is supported by the base 110 and is pivotally coupled to the hub 114 at a first pivot coupling 144, defining a first pivot axis 304. First end 142 of arm 140 can rotate about first pivot axis 304 to position second end 146 of arm 140 relative to the base 110. In the illustrated embodiment, first pivot coupling 144 includes a first friction bearing 145. The first friction bearing 145 may include a plurality of troughs and ridges (not shown) contacting the first end 142 of arm 140 and the hub 114 to pivotally maintain the position of the second end 146 of arm 140 relative to the base 110.

(13) Referring further to FIGS. 2 and 3, second end 146 of arm 140 illustratively supports sprayer assembly or sprayhead 122 which includes a neck 123. In the illustrated embodiment, flexible waterway 120 is fluidly coupled to sprayer assembly 122 which defines fluid outlet 126. In the illustrated embodiment, sprayer assembly 122 is releasably coupled to a sprayer nest or cradle 124. Sprayer nest 124 is sized to receive neck 123 of sprayer assembly 122, and sprayer assembly 122 is removably coupled to sprayer nest 124. In other illustrative embodiments, at least the sprayer assembly 122 or the sprayer nest 124 includes a magnet and at least the other of the sprayer assembly 122 or the sprayer nest 124 contains a magnetically attractive material so that the sprayer assembly 122 may be removably coupled to sprayer nest 124 with a magnet. When uncoupled from sprayer nest 124, sprayer assembly 122 may be moved relative to base 110 by the user while remaining attached (fluidly coupled) to flexible waterway 120 (FIG. 7). The sprayer assembly 122 may also include a user interface, such as a rocker switch 150, to toggle water flow between a center stream (e.g., an aerated stream) 126a or sprayer outlets 126b.

(14) Sprayer nest 124 is pivotally coupled to second end 146 of arm 140 at a second pivot coupling 148, defining a second pivot axis 308. Second pivot coupling 148 and second pivot axis 308 are laterally offset from first pivot coupling 144 and first pivot axis 304. Sprayer nest 124 can rotate about second pivot axis 308 to position sprayer nest 124 relative to second end 146 of arm 140. In the illustrated embodiment, second pivot coupling 148 includes a second friction bearing 149, the second friction bearing 149 may include a plurality of troughs and ridges (not shown) contacting the sprayer nest 124 and the second end 146 of arm 140 to pivotally maintain the position of sprayer nest 124 relative to second end 146 of arm 140.

(15) In the illustrated embodiment, first pivot coupling 144, the center of sprayer nest 124, and a point on arm 140 between first pivot coupling 144 and second pivot coupling 148 define an orientation plane 310. First pivot axis 304 and second pivot axis 308 lie within the orientation plane 310. The orientation plane 310 will shift with each arrangement of the faucet 100, and first pivot axis 304 and second pivot axis 308 will lie within the orientation plane 310 at each positioning of the faucet 100.

(16) In the illustrated embodiment, an x-axis can be defined by a line extending perpendicular to longitudinal axis 300. Second pivot axis 308 and first pivot axis 304 both lie parallel to the x-axis.

(17) With reference to FIGS. 4-6, first and second pivot couplings 144 and 148 allow a user to position sprayer assembly 122 in a plurality of locations relative to base 110. In a first or raised position (FIG. 4), first end 142 of arm 140 is rotated about first pivot axis 304 to position second end 146 of arm 140 vertically above base 110. Sprayer nest 124 is rotated about second pivot axis 308 to direct the sprayer assembly 122 vertically downward, such that fluid outlet 126 directs fluid flow vertically downward from sprayer assembly 122. From this position, faucet 100 may be repositioned to a second or intermediate position (FIG. 5) by rotating first end 142 of arm 140 clockwise from the perspective of a user in front of the faucet until second end 146 of arm 140 is positioned at an angle from longitudinal axis 300. The faucet 100 may be further repositioned to a third or lowered position by rotating first end 142 of arm 140 clockwise from the perspective of a user in front of the faucet 100 until second end 146 of arm is positioned vertically below base 110. The faucet 100 may be positioned in a plurality of positions by rotating arm 140 about first pivot axis 304 as described either clockwise or counterclockwise, and by rotating sprayer nest 124 about second pivot axis 308 either clockwise or counterclockwise to direct the sprayer assembly 122 to a plurality of positions (FIG. 6).

(18) Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the spirit and scope of the invention as described and defined in the following claims.
