DETAILED DESCRIPTION OF THE INVENTION
Referring now to the drawings of FIGS. 1 and 2, there is shown a faucet assembly 10 configured in accordance with an embodiment of the present invention. Faucet assembly 10 includes a valve body subassembly 12, a spout subassembly 14, a deck plate subassembly 16, a handle subassembly 18-1, and a handle subassembly 18-2.
Valve body subassembly 12 includes an underbody 20, a valve subassembly 22-1 and a valve subassembly 22-2. Underbody 20 includes a valve end body 24-1 configured to attachably receive valve subassembly 22-1, includes a valve end body 24-2 configured to attachably receive valve subassembly 22-2, and includes a spout receptacle 24-3 for coupling to spout subassembly 14. For example, each of valve end bodies 24-1, 24-2 may-have internal threads and each valve subassemblies 22-1, 22-2 may have external threads for engaging the external threads of valve end bodies 24-1, 24-2, respectively, to accommodate the fastening of valve subassemblies 22-1, 22-2 to underbody 20.
Valve subassembly 22-1 includes a valve mechanism 26-1 and an actuator 28-1 coupled to valve mechanism 26-1 to operate valve mechanism 26-1 when actuator 28-1 is rotated about a corresponding axis 30-1. Valve mechanism 26-1 is configured to provide a variable fluid flow from closed to full open, depending on the rotational position of actuator 28-1 about axis 30-1. The rotational range of motion of actuator 28-1 from closed to full open may be, for example, a rotation around axis 30-1 of about 90 degrees.
Valve subassembly 22-2 includes a valve mechanism 26-2 and an actuator 28-2 coupled to valve mechanism 26-2 to operate valve mechanism 26-2 when actuator 28-2 is rotated about a corresponding axis 30-2. Valve mechanism 26-2 is configured to provide a variable fluid flow from closed to full open, depending on the rotational position of actuator 28-2 about axis 30-2. The rotational range of motion of actuator 28-2 from closed to full open may be, for example, a rotation around axis 30-2 of about 90 degrees.
Spout subassembly 14 includes a spout 32 and a spout nut 33. Spout 32 has a distal end 34 which, in combination with an O-ring 36, is received for rotatable coupling to spout receptacle 24-3 of underbody 20. Spout subassembly 14 further includes a mounting collar 38 that is configured to be fixedly attached to underbody 20 via a set of fasteners, e.g., screws, 40. Spout 32 is rotatably coupled to spout nut 33 via a retainer clip 42. Spout nut 33 is then threaded onto underbody 20 at spout receptacle 24-3 to secure spout 32 to underbody 20. Alternatively, for example, spout nut 33 may be threaded into mounting collar 38.
Deck plate subassembly 16 includes a deck plate 44, a handle adapter 46-1 and a handle adapter 46-2. Deck plate 44 also may be referred to in the art as an escutcheon. Deck plate 44 has a valve opening 48-1, a valve opening 48-2 and a spout opening 48-3. Valve opening 48-1 is located in deck plate 44 such that axis 30-1 of valve subassembly 22-1 passes through valve opening 48-1 when deck plate 44 is in its desired position with respect to valve body subassembly 12. Likewise, valve opening 48-2 is located such that axis 30-2 of valve subassembly 22-2 passes through valve opening 48-2 when deck plate 44 is in its desired position with respect to valve body subassembly 12.
Handle adapter 46-1 and deck plate 44 may be configured to form an anti-rotation device 50-1 to prevent rotation of handle adapter 46-1 with respect to deck plate 44 about axis 30-1. Thus, handle adapter 46-1 is coupled to deck plate 44 to be non-rotatable with respect to deck plate 44 and corresponding axis 30-1. Anti-rotation device 50-1 may be implemented, for example, as a pair of mating flats 52-1, 54-1 formed at valve opening 48-1 and on an exterior surface of handle adapter 46-1, respectively. Handle adapter 46-1 has an access opening 56-1 to permit access to corresponding valve subassembly 22-1.
Likewise, handle adapter 46-2 and deck plate 44 may be configured to form an anti-rotation device 50-2 to prevent rotation of handle adapter 46-2 with respect to deck plate 44 about axis 30-2. Thus, handle adapter 46-2 is coupled to deck plate 44 to be non-rotatable with respect to deck plate 44 and corresponding axis 30-2. Anti-rotation device 50-2 may be implemented, for example, as a pair of mating flats 52-2, 54-2 formed at valve opening 48-2 and on an exterior surface of handle adapter 46-2, respectively. Handle adapter 46-2 has an access opening 56-2 to permit access to corresponding valve subassembly 22-2.
Those skilled in the art will recognize that anti-rotation devices 50-1, 50-2 may be implemented in other forms, such as for example, as a key and slot arrangement. Also, alternatively, deck plate 44 and handle adapters 46-1, 46-2 may be formed as a unitary structure, such as during a molding or forging process, or permanently attached by welds or adhesive.
As a further alternative, as shown in FIG. 3, a handle adapter 46-3 has external threads 64-3, and is configured to be a suitable replacement for handle adapter 46-1 and/or handle adapter 46-2. Handle adapter 46-3 together with underbody 20 form an anti-rotation device 50-3 to effect an engagement of valve handle adapter 46-3 with underbody 20 to prevent rotation of handle adapter 46-3 with respect to deck plate 44. For example, as shown in the embodiment of FIG. 3, handle adapter 46-3 may include one or more prongs 47-1 and 47-2 that engage underbody 20 to prevent rotation of handle adapter 46-3 with respect to deck plate 44 about an axis, e.g., one of axis 30-1 or axis 30-2. Alternatively, the prong(s) 47-1, 47-2 may be formed on underbody 20 to engage corresponding recesses in handle adapter 46-3. During assembly, handle adapter 46-3 would be trapped between deck plate 44 and underbody 20.
Again referring to FIGS. 1 and 2, deck plate subassembly 16 is attached to valve body subassembly 12 via the set of fasteners 40, with deck plate 44 being interposed between mounting collar 38 of spout subassembly 14 and underbody 20 of valve body subassembly 12. The set of fasteners 40 pass through corresponding holes in underbody 20 and deck plate 44, and thread into holes in mounting collar 38.
Handle subassembly 18-1 has a hub 58-1 and a valve operator 60-1. Valve operator 60-1 is rotatably coupled to hub 58-1, such that valve operator 60-1 is free to rotate when hub 58-1 is held stationary. Likewise, handle subassembly 18-2 has a hub 58-2 and a valve operator 60-2. Valve operator 60-2 is rotatably coupled to hub 58-2, such that valve operator 60-2 is free to rotate when hub 58-2 is held stationary.
As shown in FIG. 2, for example, with respect to handle subassembly 18-2, in order to rotatably couple valve operator 60-2 to hub 58-2, valve operator 60-2 may include a stem 61 that is inserted into hub 58-2, and configured to receive a retaining ring 63 to limit axial motion of valve operator 60-2 with respect to hub 58-2 and axis 30-2, while permitting rotational motion of valve operator 60-2 with respect to hub 58-2 about axis 30-2. Handle subassembly 18-1 may be configured similar to handle subassembly 18-2.
Referring again to FIG. 1, valve operator 60-1 includes an opening with internal splines (not shown) that engage external splines 62-1 of actuator 28-1 of valve subassembly 22-1 so as to connect valve operator 60-1 with actuator 28-1. Hub 58-1 is connected to handle adapter 46-1 in a manner so as to be held stationary with respect to deck plate 44 during operation of valve operator 60-1. In one embodiment, for example, hub 58-1 of handle subassembly 18-1 may have internal threads and handle adapter 46-1 may have external threads 64-1 configured to engage the internal threads of hub 58-1, wherein during assembly of faucet assembly 10, hub 58-1 is threaded onto handle adapter 46-1 and fastened tightly via engagement of the internal threads of hub 58-1 with the external threads 64-1 of handle adapter 46-1.
Accordingly, during operation, valve operator 60-1 may be rotated about axis 30-1, i.e., moving in relation to deck plate 44, which correspondingly rotates actuator 28-1 to operate valve mechanism 26-1 of valve subassembly 22-1, while hub 58-1 is held stationary with respect to deck plate 44 by the engagement of hub 58-1 with handle adapter 46-1.
Likewise, valve operator 60-2 includes an opening with internal splines 65 (see FIG. 2) that engage external splines 62-2 of actuator 28-2 of valve subassembly 22-2 so as to connect valve operator 60-2 with actuator 28-2. Hub 58-2 is connected to handle adapter 46-2 in a manner so as to be held stationary with respect to deck plate 44 during operation of valve operator 60-2. In one embodiment, for example, hub 58-2 of handle subassembly 18-2 may have internal threads and handle adapter 46-2 may have external threads 64-2 configured to engage the internal threads of hub 58-2, wherein during assembly of faucet assembly 10, hub 58-2 is threaded onto handle adapter 46-2 and fastened tightly via engagement of the internal threads of hub 58-2 with the external threads 64-2 of handle adapter 46-2.
Accordingly, during operation, valve operator 60-2 may be rotated about axis 30-2, i.e., moving in relation to deck plate 44, which correspondingly rotates actuator 28-2 to operate valve mechanism 26-2 of valve subassembly 22-2, while hub 58-2 is held stationary with respect to deck plate 44 by the engagement of hub 58-2 with handle adapter 46-2.
FIG. 4 is a flowchart of an exemplary method for assembling faucet assembly 10. Those skilled in the art will recognize that the order of the steps set forth below may be varied, and the present invention is intended to cover all viable combinations of the following steps, regardless of the actual order used.
At step S100, valve body subassembly 12 is formed.
At step S102, deck plate subassembly 16 is formed by coupling handle adapters 46-1, 46-2 to deck plate 44, such that handle adapters 46-1, 46-2 are non-rotatable with respect to deck plate 44 and corresponding axes 30-1 and 30-2, respectively. Because of handle adapters 46-1, 46-2, deck plate 44 operates as a structural member as opposed to merely a decorative cover, as in conventional faucets.
At step S104, handle subassemblies 18-1, 18-2 are formed, with each handle assembly including a hub and a valve operator. For example, valve operator 60-1 is rotatably coupled to hub 58-1 of handle subassembly 18-1, such that valve operator 60-1 is free to rotate when hub 58-1 is held stationary. Likewise, valve operator 60-2 is rotatably coupled to hub 58-2 of handle subassembly 18-2, such that valve operator 60-1 is free to rotate when hub 58-2 is held stationary.
At step S106, spout subassembly 14 is formed having spout 32 and mounting collar 38.
At step S108, mounting collar 38 of spout subassembly 14 is fixedly attached to underbody 20 via fasteners 40, with deck plate 44 of deck plate subassembly 16 being interposed between mounting collar 38 of spout subassembly 14 and underbody 20. Accordingly, mounting collar 38, i.e., the spout collar, of spout subassembly 14 rigidly couples deck plate 44 to underbody 20, thereby making deck plate 44 a structural member rather than just an esthetic covering for underbody 20. Because of this structural arrangement, handle hubs 58-1, 58-2 of handle subassemblies 18-1, 18-2 attach to deck plate 20 (by way of handle adapters 46-1, 46-2, respectively). In contrast, in conventional faucets, the handle hubs attach to the valves or valve bodies.
At step S110, spout 32 is rotatably coupled to underbody 20 by inserting distal end 34 of spout 32 into spout receptacle 24-3 of underbody 20. Spout nut 33 is then threaded onto underbody 20 at spout receptacle 24-3 to secure spout 32 to underbody 20.
At step S112, valve operator 60-1 is connected to the corresponding actuator 28-1 of the corresponding valve subassembly 22-1 to operate valve subassembly 22-1 by rotating the corresponding actuator 28-1 about axis 30-1. Likewise, valve operator 60-2 is connected to the corresponding actuator 28-2 of valve subassembly 22-2 to operate valve subassembly 22-2 by rotating the corresponding actuator 28-2 about the respective axis 30-2.
At step S114, hub 58-1 is connected to corresponding handle adapter 46-1, so that hub 58-1 is held stationary with respect to deck plate 44 during rotation of the corresponding valve operator 60-1 about axis 30-1. Likewise, hub 58-2 is connected to corresponding handle adapter 46-2, so that hub 58-2 is held stationary with respect to deck plate 44 during rotation of the corresponding valve operator 60-2 about the respective axis 30-2.
Accordingly, during operation of faucet assembly 10, valve operator 60-1 is rotated about axis 30-1, i.e., moving in relation to deck plate 44, which correspondingly rotates actuator 28-1 to operate valve mechanism 26-1 of valve subassembly 22-1, while hub 58-1 is held stationary with respect to deck plate 44 by the engagement of hub 58-1 with handle adapter 46-1. Likewise, valve operator 60-2 is rotated about axis 30-2, i.e., moving in relation to deck plate 44, which correspondingly rotates actuator 28-2 to operate valve mechanism 26-2 of valve subassembly 22-2, while hub 58-2 is held stationary with respect to deck plate 44 by the engagement of hub 58-2 with handle adapter 46-2.
While this invention has been described with respect to embodiments of the invention, the present invention may be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
