Faucet with spray head

Abstract

Disclosed is a swivel faucet, such as one having a pull-out sprayer. In one aspect the inlet and outlet lines are formed in an integral structure with a transverse plate that faces a mixing valve. In another aspect the control handle for the faucet is provided with a concentric visible bore and hidden set screw bore combined with a bushing having a cutout to facilitate their use. In still another aspect there is provided a bearing that mounts to a pivotable sprayer and provides distinct swivel positions through the use of a detent connection to a land.

Claims

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(16) Referring now to the drawings, and more particularly first to FIGS. 1, 2 and 11, there is shown a faucet assembly 20 which includes spray head 22 connected to a flexible outlet line 24 which is routed through spray head harbor 26. Spray head 22 may optionally include a spray control pushbutton 28, and may also include other controls. Spray head harbor 26 is connected to valve housing 30 via bearing 32.

(17) Mixing valve 34 is connected to control handle 36, as also shown in FIGS. 3 and 4. Tilting and/or rotation of control handle 36 determines the combination of hot and cold water and/or the volume of water available to spray head 22 via flexible outlet line 24. The valve used for this purpose may be any of a number of conventional mixing valves.

(18) Inlet/outlet assembly 38 (see particularly FIGS. 2,5 and 12-14) is in fluid communication with mixing valve 34. The inlet/outlet assembly 38 has inlet lines 40 and outlet line 24 permanently affixed to a face plate 42 as by casting to integrally form them together, or by welding/brazing to essentially permanently bond them together.

(19) It is highly preferable to form face plate 42 transverse to the longitudinal axis of inlet lines 40. Face plate 42 extends vertically without the need for a separate elbow, and each of the three lines bends from the vertical to the horizontal in a way that minimizes the need for a bulge. In this regard, it is particularly desirable that the lines have a sideways bend in them which permits a more compact front-to-back bending because part of the radius is extended side-to-side rather than just front-to-back.

(20) One of inlet lines 40 is designed to be connected to a hot water supply and the other of inlet lines 40 is designed to be connected to a cold water supply. The inlet lines 40 are in fluid communication with the respective inputs of mixing valve 34. Flexible outlet line 24 is in fluid communication with an outlet of mixing valve 34. Appropriate movement of control handle 36 regulates the mixing of the hot and cold inputs, and can also control the flow volume, which are available to spray head 22 via flexible outlet line 24.

(21) Flexible outlet line 24 extends downwardly from the mixing valve 34 at face plate 42, through valve housing 30, then upward back through valve housing 30, spray head harbor 26, to link to spray head 22. Flexible outlet line 24 has weight 44 slidingly adapted thereto to bias flexible outlet line 24 in a downward orientation thereby facilitating the automatic retraction of flexible outlet line 24 when spray head 22 is returned to a home position in spray head harbor 26.

(22) As may be best appreciated from FIGS. 3 and 4, control handle 36 includes a set screw bore 46, which is treaded, which is separate, but circumferentially aligned with a visible bore 48 in an outer wall 51 of the handle. Visible bore 48 provides access to tighten a set screw 50 within set screw bore 46, which attaches an inner wall 52 of handle 36 to a valve stem 54 of mixing valve 34.

(23) In order to control the mixing of the hot and cold inputs, and the volume of flow output from valve 34, valve stem 54 rotates and tilts. A bushing 55 is included with a keyhole shaped cutout 56 (see FIG. 2) thereby providing a greater range of motion of handle 36, without the need for an exposed cutaway in handle 36.

(24) To further improve the decorative nature of the assembly, and also to prevent moisture from reaching the set screw connection, there can be a cap 58 which removably covers visible bore 48. It may be made of a flexible plastic. Further, as shown in FIG. 3, an O-ring seal 49 may be mounted on the cap to help keep water out from the handle interior.

(25) Referring now mostly to FIGS. 7-10 and 15, bearing 32 has an outer contour 60 and a base 62. Outer contour 60 is mateable with an inner contour of spray head harbor 26. Base 62 includes a projection 64 mounted on a flexible arm 74.

(26) Valve housing 30 has a tubular shaft 68 extending up from a land 68 for base 62. Land 68 has a detent/depression 70. Bearing 32 is rotatable on shaft 66 between a position where projection 64 is within detent 70 (FIG. 10), and another position where projection 64 is not within detent 70 (phantom line in FIG. 9). When the projection 64 aligns with the detent 70, the spray head harbor 26 will be perfectly aligned automatically with the valve housing below it.

(27) Another feature of bearing 32 is that it includes a vertical slit 72 so that it can be compressed to be jammed into spray head harbor 26. Projection 64 on the bottom of bearing 32 is supported by a spring arm 74. When bump projection 64 aligns with detent 70, it therefore snaps into it, notifying the user that they have the right positioning. However, further swiveling force on the support or spray head can reinstate the swinging movement by driving the bump out of the recess. Of course, alternatively, detent 70 can be on base 62 and projection 64 can be on land 68.

(28) The preferred embodiments of the present invention can also include a variety of other fittings, bushings, nozzles, washers, nuts and other fasteners, and other desirable plumbing components, as will be appreciated by those skilled in the art.

(29) In a typical installation the faucet assembly 20 will be mounted on a rear mounting ledge of a double basin kitchen sink, or directly behind a multiple basin kitchen sink. Of course, the present invention could be otherwise installed in connection with other plumbing fixtures and fittings. For example, it could be used with a laundry sink.

(30) Various other alternatives are intended within the scope of the invention. For example, in some embodiments the swivel locator could be used without the inlet/outlet assembly or the decorative handle features. In other embodiments the inlet/outlet assembly could be used without the swivel locator or the decorative handle features. In any event, the present invention is not to be limited to the features of just the most preferred embodiments.

INDUSTRIAL APPLICABILITY

(31) The present invention provides faucets, preferably pull-out spray faucets, with the capability of linking supply and outlet lines in a compact manner, attaching a decorative control handle, and having positive feel positioning for the swivel spout.
