DETAILED DESCRIPTION

Before turning to the figures, which illustrate certain exemplary embodiments in detail, it should be understood that the present disclosure is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology used herein is for the purpose of description only and should not be regarded as limiting.
Generally speaking, most traditional hand-held, pull-out sprayers are attached to a flexible hose and may be capable of extending away from a faucet via the flexible hose. Some hand-held sprayers are capable of automatically retracting back into the faucet (e.g., by a biasing force of the hose, etc.), so as to facilitate docking of the sprayer to the faucet. However, when the hand-held sprayer returns to the faucet when docking, the hand-held sprayer may experience excessive force and become damaged over time. Additionally, the hand-held sprayer may experience an insufficient force and not retract fully back into the faucet or be improperly docked. Therefore, it would be advantageous to provide a faucet assembly that is capable of receiving a hand-held sprayer and returning the hand-held sprayer to an original, docked position on the faucet without the use of excess force and in a more reliable and consistent manner, as compared some traditional hand-held, pull-out sprayers.
Referring generally to the figures, a faucet assembly 100 having a hand-held sprayer 110 is shown according to an exemplary embodiment. The hand-held sprayer 110 is biased to a retracted, docked position on the faucet such that a portion of the hand-held sprayer is flush with a portion of the spout 104 of the faucet assembly 100 using a slow-close insert assembly 200. The hand-held sprayer 110 is operable (e.g., by a user, etc.) from the retracted, docked position to an extended position via the slow-close insert assembly 200. In the extended position, the hand-held sprayer 110 is operable (e.g., by a user, etc.) to dispense water in a plurality of directions and/or a plurality of spray modes.
The slow-close insert assembly 200 includes an outer sleeve 210 and an inner sleeve 220. The outer sleeve 210 is structured to couple to an inner surface of the spout 104. The inner sleeve 220 is operable between a first position (e.g., a closed position) and a second position (e.g., an open position). The slow-close insert assembly 200 includes one or more damping elements (e.g., a spring, a damper, etc.) shown as springs 250, which can, advantageously, help to facilitate a slow-close action as the inner sleeve 220 transitions between the first position and the second position.
Referring now to FIG. 1 , a side view of the faucet assembly 100 is shown. The faucet assembly 100 is structured to receive water at a proximal end from a supply line (e.g., a hot water supply line, a cold water supply line) and dispense the water at a distal end. The faucet assembly 100 includes a spout 104 and a hand-held sprayer 110. In some embodiments, the faucet assembly 100 may be configured to have an ornamental exterior (e.g., brass, stainless steel, etc.). In some embodiments, the faucet assembly 100 includes mounting hardware structured to couple the faucet assembly 100 to a counter top. In some embodiments, the faucet assembly 100 also includes various valves and/or handles structured to modify a parameter (e.g., flow rate, temperature, etc.) of water flowing through the faucet assembly 100. In additional embodiments, the ornamental exterior may be configured to match nearby fixtures in, for example, a kitchen environment. The faucet assembly 100 may be a pull-down faucet assembly in a kitchen, according to an exemplary embodiment. The faucet assembly 100 may be used in a variety of different environments, including kitchens, bathrooms, showers, or other types of environments.
Referring now to FIG. 2 , a cross section view of the faucet assembly 100 is shown. The faucet assembly 100 is shown to further include a hose 112 (e.g., flexible hose, etc.) that is structured to receive water from a water supply (e.g., a hot/cold supply line, downstream a mixing valve, etc.) and provide the water to the hand-held sprayer 110. The faucet assembly 100 is also shown to include a slow-close insert assembly 200 disposed at a distal end of the spout 104. As shown in FIGS. 1 and 2 , the hand-held sprayer 110 is biased to a retracted position such that a portion of the hand-held sprayer 110 is flush with the spout 104 in a docked position on the spout 104. In the retracted or docked position, the hand-held sprayer is substantially stationary and is structured to dispense water received via the hose 112. The hand-held sprayer 110 is operable from the retracted to an extended position. In the extended position the hand-held sprayer 110 is operable to dispense water in a plurality of directions and/or a plurality of spray modes.
Referring to FIGS. 3-4 , perspective views of the slow-close insert assembly 200 are shown, according to an exemplary embodiment. The slow-close insert assembly 200 includes an outer sleeve 210 and an inner sleeve 220. The inner sleeve 220 is positioned at least partially within the outer sleeve 210. In some embodiments, the outer sleeve 210 has a first annular wall and the inner sleeve 220 has a second annular wall. The first annular wall and the second annular wall define a central axis (shown as central axis 130 in FIG. 6 ). According to an exemplary embodiment, the inner sleeve 220 is operable between a first position (e.g., a closed position) shown in FIG. 3 and a second position (e.g., an open position) shown in FIG. 4 . The slow-close insert assembly 200 is structured to be positioned at a distal end of a spout (e.g., the spout 104 of FIG. 1 ). In some embodiments, the outer sleeve 210 is at least partially flexible such that the outer sleeve 210 follows a curvature of a spout. Further, the central axis may be curved or arced in shape. Accordingly, the slow-close insert assembly 200 may be used in a wide variety of faucet assemblies having different spouts and/or spout curvatures.
The outer sleeve 210 includes a slot that defines a track 212. The track 212 may be positioned on a first surface of the outer sleeve and extend partially or fully through the first surface. The inner sleeve 220 includes a protrusion shown as key 222 that is positioned within the slot such that the key 222 moves along the track 212 as the inner sleeve 220 transitions between the first position and the second position.
The outer sleeve 210 also includes at least one tab 214. The tab 214 extends radially outward form the central axis. The tab 214 is structured to facilitate coupling the outer sleeve 210 to an inner surface of the spout 104. In some embodiments, the tab 214 is structured to snap-fit to the inner surface of the spout 104. According to other exemplary embodiments, the tab 214 facilitates an interference or press-fit arrangement with the inner surface of the spout 104.
The outer sleeve 210 also includes at least one retention slot 216. The retention slot 216 may be a hole formed through the outer sleeve 210. In some embodiments, the outer sleeve 210 includes two or more retention slots. The retention slot 216 is structured to receive an extended portion (e.g., pin, tab, or other protrusion), shown as pin 226 when the inner sleeve 220 is in the second position.
The outer sleeve 210 also includes at least one protrusion shown as retention notch 218. The retention notch 218 extends radially inward from an inner surface of the outer sleeve 210. The retention notch is structured to couple to a portion of a damping element shown as springs 250. In some embodiments, the springs 250 are also structured to couple to the pin 226. The springs 250 are disposed at least partially between the outer sleeve 210 and the inner sleeve 220 within a recess 240 of the inner sleeve 220. The springs 250 may be configured to assist (e.g., facilitate, provide, etc.) the functionality slow-close insert assembly 200 by damping movement of the inner sleeve 220 between the first position and the second position and/or by biasing the inner sleeve 220 toward the first position.
Although the damping element is shown as a springs 250, in some embodiments, the damping element may include one or more springs, one or more dampers, and/or other mechanical damping elements. In some embodiments, when the inner sleeve 220 is in the first position, the springs 250 are in a substantially uncompressed and/or un-stretched state (e.g., substantially at equilibrium). In some embodiments, when the inner sleeve 220 is in the second position, the springs 250 are structured to extend between the retention notch 218 and the pin 226 such that the springs 250 are in a stretched or extended state. In some embodiments, when the inner sleeve 220 is in the second position and the pin 226 is disposed within the retention slot 216, the springs 250 do not have enough biasing force to disengage the pin 226 from the retention slot 216. In these embodiments, an outside force is required to disengage the pin 226 from the retention slot 216. When the pin 226 is disengaged from the retention slot 216, the springs 250 have sufficient biasing or return force to move the inner sleeve 220 to the first positon.
Still referring to FIGS. 3 and 4 , the inner sleeve 220 is structured to be positioned at least partially within the outer sleeve 210. The inner sleeve includes flanges 224 that are flexible and are oriented outward at an angle radially away from the central axis in an unflexed or original position. In some embodiments, when the inner sleeve 220 is in the first position, an inner surface of the outer sleeve 210 forces the flanges 224 to flex inwards such that the flanges 224 are deflected to be oriented substantially parallel to the central axis and/or to the inner surface of the outer sleeve 210. In some embodiments, when the inner sleeve 220 is in the second position the flanges 224 automatically deflect outwards due to the biasing force. In some embodiments, and as shown in FIGS. 3 and 4 , the flanges 224 each include jaws 242. The jaws 242 define a circular or partially circular opening that is centered on the central axis. The jaws 242 may deflect with the flanges 224 when the inner sleeve 220 is in the first position such that the jaws 242 grasp or couple to a portion of the hand-held sprayer 110 and/or the hose 112. When the inner sleeve 220 is in the second position, and the flanges 224 deflect outwards from the central axis due to the biasing force, the jaws 242 are structured to release or de-couple from the portion of the hand-held sprayer 110 and/or the hose 112 to allow for extension of the hose 112 from the faucet.
FIG. 5 is a detailed perspective view of the slow-close insert assembly 200, according to an exemplary embodiment. The pin 226 is shown protruding at least partially through the retention slot 216. Additionally, the springs 250 are shown coupled to the pin 226
FIGS. 6-7 are cross section views of the faucet of FIG. 1 including the slow-close insert assembly 200 of FIG. 3 . The slow-close insert assembly 200 is shown disposed within the spout 104. The hose 112 at least partially extends through the central axis of the slow-close insert assembly. The hand-held sprayer 110 is also at least partially disposed within and/or below (e.g., downstream) the slow-close insert assembly 200.
Referring specifically to FIG. 6 , the hand-held sprayer 110 is shown to include a socket portion 114, a conical nut 116, and a water chamber portion 118, and a ball fitting 120. The socket portion 114 is structured to receive the ball fitting 120. The ball fitting 120 is structured to freely rotate within the socket portion 114. The ball fitting is also structured to couple to the hose 112. The socket portion 114 may be sealable coupled to the water chamber portion 118. The conical nut 116 is coupled (e.g., threadably coupled) to the water chamber portion 118 such that the conical nut 116 compresses the socket portion 114 into the water chamber portion 118 forming a fluid-tight seal therebetween.
Still referring to FIG. 6 , a flow path 150 is shown. The flow path 150 generally depicts where water flows within the faucet assembly 100. In particular, the flow path 150 is within the hose 112, the ball fitting 120, the socket portion 114, the water chamber portion 118, and exits the hand-held sprayer 110 at a distal end.
As shown in FIG. 6 , the inner sleeve 220 is in the first position and the jaws 242 are grasping a portion of the ball fitting 120. Additionally, the outer sleeve 210 is structured to couple to the inner portion of the spout 104 in a snap-fit arrangement. Specifically, the tab 214 is disposed within a tab slot 106 of the spout 104.
Now referring to FIG. 7 , the ball fitting 120 is shown to include a proximal portion 122, a central portion 124 and a distal portion 126. The proximal portion 122 is structured to receive a portion of the hose 112. The central portion 124 has a radius that is smaller than the radius of the proximal portion such that the jaws 242 can grasp the ball fitting 120 at the central portion 124. The distal portion 126 is structured to have a substantially spherical shape such that the ball fitting 120 can freely rotate within the socket portion 114.
Still referring to FIG. 7 , the outer sleeve 210 is shown to apply a radially inward force (shown by arrows) on the inner sleeve 220 such that the flanges 224 are deflected inwards towards a central axis 130. In this position, the jaws 242 grasp the hand-held sprayer 110 at ball fitting 120 (e.g., at the central portion 124 and/or between the proximal portion 122 and the conical nut 116).
FIG. 8 is a cross section view of the faucet assembly 100 including the slow-close insert assembly 200. When the hand-held sprayer 110 is removed from the spout 104, the inner sleeve 220 transitions to the second position, as shown in FIG. 8 . As the inner sleeve 220 transitions form the first position to the second position, the springs 250 at least partially resist the movement of the inner sleeve. The flanges 224 are deflected outwards (e.g., away from the central axis 130) by the biasing force (shown by arrows). The jaws 242 are also deflected outwards and the opening defined by the jaws 242 is wide enough such that the proximal portion 122 (and the hose 112) can fit through the opening defined by the jaws 242. Accordingly, the hand-held sprayer can be operated to dispense water in a plurality of directions and/or a plurality of spray modes.
Still referring to FIG. 8 , when the hand-held sprayer 110 is returned to the spout 104 at the docked position, the conical nut 116 is structured to force the pin 226 out of the retention slot 216. As the pin 226 is removed from the retention slot 216, the central portion 124 of the ball fitting 120 aligns with the jaws 242 such that the jaws 242 may deflect inwards without interference from the larger diameter proximal portion 122. The springs 250 also begin operating the inner sleeve 220 to the first position in a slow-close action. As the inner sleeve 220 moves to the first position, the outer sleeve 210 applies a radially inward force to deflect the flanges 224 inward causing the jaws 242 to grasp the hand-held sprayer 110 at the central portion 124 of the ball fitting 120. The slow-close action created by the springs 250 is substantially slow and free of excess force or perturbations. In some embodiments, as the inner sleeve 220 returns to the first or docked position, the outer sleeve 210 supplies a frictional interference to assist in the slow-close action of the inner sleeve. In this manner, the disclosed insert assembly 200 facilitates extension and docking of a handheld sprayer in a more reliable and consistent manner, as compared to other faucets with pull-out sprayers.
