DETAILED DESCRIPTION

[0073] FIGS. 7-11 show an enclosure 100 with an integrated hydrant of one embodiment of the present invention. The enclosure 100 is defined by a plate 104 with an outwardly-extending lip 108. The plate 104 has an inner surface 112 and an outer surface 116. The plate 104 also has a recess 106 that extends from the inner surface 112 toward the outer surface 116. The plate 104 also includes an opening 124 that receives a control rod and stem screw has shown in FIG. 4. The inner surface 112 is adapted to receive a backflow preventer 120. The backflow preventer 120 is positioned within the recess 106 such that an outer edge of the backflow preventer 120 does not extend from the inner surface 112 to an extent that adversely affects door closure.

[0074] FIGS. 9 and 10 show a rear portion of the enclosure 100. The recess in the plate forms an outwardly-extending protrusion 132, which in one embodiment is frusto-conical. The protrusion 132 has an outer surface that includes an opening (not shown) that communicates with a conduit 136 that connects fluid supply tube 140 to the backflow preventer. Those of skill the art will appreciate that the fluid supply tube 140 may be directly interconnected to the protrusion 132, but such configuration may not be ideal as the size of the valve 144, or length of the fluid supply tube 140 would have to be increased or lengthened, which will increase material costs. The outer surface 116 of the plate also includes a boss 148 that supports the control tube 152.

[0075] In operation, the user turns a key interconnected to the stem screw 128, which removes the plunger from the valve 144 and allows fluid to escape through the fluid supply tube 140. One of skill in the art will appreciate that other mechanisms to control fluid flow besides a plunger may be use without departing from the scope of the invention. Fluid exits the hydrant by a backflow preventer 120. Turning the key in the opposite direction places the plunger into engagement with the valve 144 to cease fluid flow through the fluid supply tube 140. After the hydrant is shut off, fluid may remain in the fluid supply tube 140 and the control tube 152. Thus, in one embodiment, the fluid supply tube 140 and the control tube 152 are angled relative to the outer surface 116 of the hydrant so fluid will leak from the hydrant after the valve closes.

[0076] One embodiment of the present invention includes a door 162 as shown in FIGS. 7-11. The door 162 is hingedly interconnected to a hinge plate 166 interconnected to the lip 108. In some embodiments the hinge plate is interconnected to the plate inner surface 112. Here, the hinge plate 166 includes a plurality of protrusions 170 that receive fasteners 174 that engage the inner surface 112. The fasteners are alternatively interconnected to the lips. The door 162 may also include a lock 178 that selectively engages a protrusion 182 extending from the inner surface 112. If the door becomes damaged or the user changes the look of the door 162, the door 162 can be opened to expose the fasteners 174. The fasteners are then removed and a new door is interconnected to the plate 104.

[0077] The internal volume of the enclosure 100 may be increased to accommodate one or two fluid flow supply tubes and associated backflow preventers. More specifically, some hydrants include hot and cold water delivery means and it is within the skill of those of skill in the art to expand the size of the enclosure to accommodate the same.

[0078] FIGS. 12-19 show an enclosure 200 having integrated hydrant of another embodiment of the present invention. The enclosure 200 is defined by a plate 204 with an inner surface 212 and an outer surface 216. The plate 204 has a recess 206 that extends from the inner surface 212 toward the outer surface 216. The plate 204 also includes an opening 224 that receives a control rod and stem screw 228 as shown in FIG. 4.

[0079] The inner surface 212 is adapted to receive a backflow preventer 220. The backflow preventer 220 is positioned within the recess 206 such that an outer edge of the backflow preventer 220 does not extend from the inner surface 212 to an extent that adversely affects door closure.

[0080] FIGS. 13, 15, and 19 show a rear portion of the enclosure 200. The recess in the plate forms outwardly-extending protrusion 232, which in one embodiment is frusto-conical. The protrusion 232 has an outer surface that includes an opening (not shown) that communicates with a conduit 236 (see FIG. 17) that connects fluid supply tube 240 to the backflow preventer. Those of skill in the art will appreciate that the fluid supply tube 240 may be directly interconnected to the protrusion 232, but such configuration may not be ideal as the size of the valve 244, or length of the fluid supply tube 240 would have to be increased or lengthened, which will increase material costs. The outer surface 216 of the plate also includes a boss 248 that supports the control tube 252.

[0081] In operation, the user interconnects the key to the stem screw 228 and turns the same, which removes the plunger from the valve 244 and allows fluid to escape through the fluid supply tube 240. Fluid travels through the conduit 236 along fluid flow path 298 and exits the backflow preventer 220. Turning the key in the opposite direction places the plunger back into engagement with the valve 244 to cease fluid flow through the fluid supply tube 240. After the hydrant is shut off, fluid is left in the fluid supply tube 240 and the control tube 252.

[0082] The door 262 of this embodiment includes a lip 292 and is hingedly interconnected to the plate 204. As shown in FIG. 15, the door 262 may be interconnected to the plate 204 by removable pins 294. The door 262 may also include a lock 278 that selectively engages a protrusion 282 extending from the inner surface 212.

[0083] FIG. 20-23 show another embodiment of the present invention. Here, the enclosure 300 includes a door 362 having a peripheral lip 392. The door also includes a lock 378. The remaining structure of the hydrant and enclosure are, or may be, similar to that described above regarding FIGS. 7-19. A door 362 is interconnected to a plate (also sometimes known as a face plate) 312 by a hinge 314. The protrusion 332 extends from the plate 312 associated with a fluid supply tube 340 also interconnected to a valve 344. The valve 344 is also interconnected to a control tube 352 associated with the plate 312. The protrusion 332 defines a recess 306 for receipt of a backflow preventer 320. The plate also includes an opening 324 associated with a stem screw 328 operatively interconnected to a plunger that opens and closes the valve 344. The door 362 may include a lock 378 that selectively interfaces with the plate 312, or a protrusion extending therefrom. One of skill in the art will appreciate that the plate 312 may be associated with a building wherein a rear surface of the plate coincides with the building's outer surface. Alternatively, the hydrant may be affixed to a building wherein the door, when closed, generally coincides with the external building surface; e.g., siding, brick, stone, etc. That is, the plate may be inset relative to the outer surface such that the outer surface of the door 362 would be generally flush with the external surface of the dwelling when the door 362 is closed. In some embodiments of the present invention, the door 362 is textured or otherwise customized to match, or substantially match, the texture and color of the external building service.

[0084] FIGS. 24-27 show yet another embodiment of the present invention, which is very similar to that shown in FIGS. 20-23. Here, however, the hinge 414 is of a different configuration. The enclosure 400 includes a door 462 having a lock 478. The door selectively interfaces with a plate 412. The plate 412 includes a recess 406 that accommodates a backflow preventer 420, and an opening 444 associated with a stem screw 428. The plate 412 also includes a protrusion 432 interconnected to a fluid supply tube 440 also interconnected to a valve 444. The valve also receives a control tube 452 as in the embodiments described above. The door 462 may include a lip 492. In this embodiment of the present invention, a hinge plate 496 is provided that is interconnected to the plate 412 by a plurality of fasteners 498.

[0085] FIGS. 28-33 show yet another embodiment of the present invention that employs a enclosure 500 with a door 562, which may also include a lock 578. Here, the plate 612 is associated with a pocket 564. In a first configuration the door 562 is closed and an inner surface thereof is abutted against the plate 512, which conceals a backflow preventer 520 and a stem screw 528. The backflow preventer 520 is recessed relative to the front surface of the plate 512 and is situated within a recess 506. The pocket 564 extends rearwardly from the plate 512 towards a valve 544 which, as in the embodiments described above, is interconnected to a fluid supply tube 540 and a control tube 552. In the second configuration, the door 562 is rotated away from the plate 512, which generally aligns the door with an internal volume of the pocket 564. The door 562 is slid into the pocket 564 and at least partially concealed. In this embodiment of the present invention, the enclosure 500 may be attached to a building wherein the front surface of the plate 512 is generally flush with the building's external surface. This contemplated hydrant placement creates an aesthetically pleasing look and prevents the hydrant and interconnected components from being damaged by items moving external to the building, e.g., a vehicle, a cart, etc.

[0086] FIGS. 34-40 illustrate how embodiments the present invention may be incorporated into existing hydrants. More specifically, FIG. 34 shows an existing hydrant assembly (Zurn model Z1310) made by design Zurn Industries, LLC. Zurn's hydrant includes a plate 512 that accommodates a backflow preventer 620 and a stem screw assembly 628. The plate 612 is interconnected to a housing 602 by a plurality of fasteners 606. In one embodiment of the present invention, a hinge plate 664 is provided that includes a hinge is also interconnected to a door 662. The door 662 may include a lock 678. The hinge plate 664 is interconnected to the plate 612 by removing one or more fasteners 606 and abutting a portion of the hinge plate 664 onto the front surface or rear surface of the plate 612. Thus the existing hardware is repurposed such that a door 662 can be utilized.

[0087] In other embodiments, however, the plate 612 is discarded and a new plate having an integral hinge plate and door is provided. The new plate with a hinge plate may also include a means for interfacing with the lock 678. Stated differently, some embodiments contemplate removing an existing plate of a to-be-installed, or installed, hydrant and replacing it with a new plate having an integral hinge plate and door.
