Embodiments of the present invention are generally related to an enclosure for concealing and protecting a hydrant.
Wall hydrants generally comprise a support plate with interconnected faucet, a means to control fluid flow through the faucet, a fluid supply tube, a valve, and a tube that contains a mechanism operates the valve. Those of skill in the art will appreciate that the fluid supply tube can also include the means to control the fluid flow.
Protective enclosures that conceal and protect hydrants are common and often incorporated into interior or exterior building walls. Enclosures are generally comprised of a box with an interconnected door. The enclosure prevents operation of the faucet, prevents theft of hydrant components (e.g., brass), protects the hydrant from environmental elements, and provides a means to incorporate the hydrant into a wall.
The enclosure door may be selectively locked. Enclosures are made in various sizes and shapes and may accommodate a single or dual hydrant. Existing enclosures are rigidly mounted to a wall and are difficult to replace. That is, if an enclosure is in need of repair, the hydrant must be disconnected, the hydrant removed, and the box must be removed from the wall. One of skill the art will appreciate that this method of repair is inefficient as, often, only the door is damaged. For example, keys that are used to open door locks are often lost, and maintenance personnel often pry the door open, which damages the door. Thereafter, the door must be replaced to ensure that the door can be locked or closed properly.
Referring now to
In operation, the user interconnects the key 46 to the stem screw 50. The stem screw 50 is operatively interconnected to the control rod 54. Turning the key 46 moves the control rod 54 and moves the plunger 62 away from a valve 34 to allow fluid flow through the fluid supply tube 30 as shown in
The enclosure 66 that receives the wall hydrant is shown in
Those of skill in the art will appreciate enclosures are difficult to install, are heavy, and sometimes, difficult to use. More specifically, as the plate 10 and associated backflow preventer 50 are inset relative to a front edge 78 of the box 70, it is often difficult for users to engage the key 46, or turn a knob, to initiate fluid flow. Further, if the door 74 is damaged, the entire enclosure 66 must be removed.
It is thus a long felt need to provide a hydrant enclosure that is easy to install, easy to use, that accepts various types of fluid connections, and has a replaceable door. These and other features, alone or in combination, are provided by the embodiments the present invention, which will be described below.
It is one aspect of embodiments of the present invention to provide an enclosure with an integrated hydrant. More specifically, one embodiment is a hydrant enclosure defined by a plate with an outwardly-extending lip. The plate also includes at least one cavity recessed relative to a plate inner surface toward a plate outer surface. The recess allows for larger components, such as backflow preventers and control knobs, to be accommodated when the enclosure door is closed. The enclosure of this embodiment is smaller and more compact than those of the prior art.
It is another aspect of embodiments of the present invention to provide an enclosure that saves material. More specifically, the fluid control tube and fluid delivery tube are directly interconnected to the box and a support plate is omitted. Further, the recess is in fluidic communication with a fluid supply boss. Unlike the prior art systems, the fluid supply boss is interconnected to a conduit integrated into the box that provides fluid to the recess that receives a backflow preventer. Materials, such as brass, steel, iron, etc. commonly associated with prior hydrant plates are integrated directly into the enclosure plate, thus significant material savings are realized.
It is yet another aspect of embodiments of the present invention to provide an enclosure with a selectively removable door. The door may be interconnected to the lip extending from the plate. The door may also be fastened to the plate outer surface and selectively interconnected thereto which allows door replacement. Those of skill in the art will appreciate that the door will wear or be damaged. Instead of removing the enclosure from the wall, embodiments of the present invention allow the door to be removed from the enclosure and replaced.
It is still yet another aspect of embodiments the present invention to provide an aesthetically pleasing door. More specifically, the size of the hydrant enclosure and associated door may be modified to accommodate larger fluid supply mechanisms. The door may be made to correspond to the dimensions and character of building materials, such as stone or brick. In one embodiment, an outer surface of the door is textured or painted to match brick such that the hydrant is substantially hidden when not in use.
These and other advantages will be apparent from the disclosure of the invention(s) contained herein. The above-described embodiments, objectives, and configurations are neither complete nor exhaustive. As will be appreciated, other embodiments of the invention are possible using, alone or in combination, one or more of the features set forth above or described below. Further, The Summary of the Invention is neither intended nor should it be construed as being representative of the full extent and scope of the present invention. Moreover, references made herein to “the present invention” or aspects thereof should be understood to mean certain embodiments of the present invention and should not necessarily be construed as limiting all embodiments to a particular description. The present invention is set forth in various levels of detail in the Summary of the Invention as well as in the attached drawings and the Detailed Description of the Invention and no limitation as to the scope of the present invention is intended by either the inclusion or non-inclusion of elements, components, etc. in this Summary of the Invention.

In operation, the user interconnects the key to the stem screw 120 and turns the same, which removes the plunger from the valve 144, which allows fluid to escape through the fluid supply tube 140. Fluid exits the backflow preventer 120. Turning the key in the opposite direction places the plunger back into engagement with the valve 144 to cease fluid flow through the fluid supply tube 140. After shut off, fluid may be 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 plunger is seated in the valve.
One embodiment of the present invention includes a door 162 as shown in
Indeed, 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.
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.
In operation, the user interconnects the key to the stem screw 220 and turns the same, which removes the plunger from the valve 244, which 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 shut off, fluid may be in the fluid supply tube 240 and the control tube 252. Thus, in one embodiment, the fluid supply tube 240 and the control tube 252 are angled relative to the outer surface 216 of the hydrant so fluid will leak from the hydrant after the plunger is seated in the valve.
The door 262 of this embodiment includes a lip 292 and is hingedly interconnected to the plate 204. As shown in
