Description

ROOF MOUNTING HYDRATING POTATO DESCRIPTION OF THE INVENTION The embodiments of the present invention are generally related to a system for interconnecting a hydrant to the roof of a building or other structure. There is a growing need for a convenient and strong water source, among other things, to clean condenser coils and wash windows in buildings. Hydrants and keys are often used on roofs, but they leak and have little structural support to accommodate the movement of a hose, for example. To try to address this issue, water faucets or hydrants are currently integrated into the rooftop attics, secured to a box or secured to a bollard, methods to provide a source of water that have many drawbacks. For example, the attic structure may not offer sufficient support, the bonding scheme may be prone to leakage, the protection to freezing may be insufficient and / or the bonding location may not be close to the required areas of use. In addition, the prior art systems are often heavy and difficult to interconnect and also provide unacceptable infiltration paths to the structure. Therefore, there is a need for a hydrant that can be hermetically mounted generally in a roof and still be substantially resistant to freezing. In this way, a need that has been perceived for some time is to provide a system of access to water for the roof of a building, which is easy to install and which is substantially leak-proof and freezing. The following description describes a device that provides structural support to a rooftop hydrant system. One aspect is to provide a support for interconnection to a roof that secures a hydrant. More specifically, one embodiment of the present invention is a hydrant support that is interconnected to the roof platform of a building that includes a weather-tight sealing system, which interrelates with the vertical pipe of a traditional hydrant. The contemplated assembly includes a vertically oriented hydrant holder having a flange for interconnection to the roof. A sleeve is also employed, by the embodiments of the present invention, which helps to ensure that fluids are prevented, for example, from entering the building. The embodiments of the present invention employ a sleeve constructed of material suitable for sealing the structure when in use and for providing weather resistance, for example, monomeric ethylene-propylene diene rubber (EPDM) with UV light protection. The hydrant support can also be adapted with shielding material to mask the hydrant support. It is also visualized that at least one wedge can be included to facilitate the interconnection between the hydrant support and the roof. Preferably, a two degree wedge is used which is placed under the hydrant support to help ensure that the hydrant support is generally oriented vertically. One skilled in the art, however, will appreciate that the flange associated with the hydrant holder can be constructed of varying thicknesses to compensate for the inclination of the roof. Another aspect of the present invention is to provide a system for supporting a hydrant that is easy to install. More specifically, the embodiments of the present invention allow the interconnection of a hydrant to a roof by means of a hydrant support, wherein the hydrant support and associated sleeve are separable and easily interconnected to the vertical pipe. In addition, it is contemplated that a flange be used in conjunction with the hydrant support that is located under the roof, which is used to sandwich the roof between the hydrant support flange and the flange located under the roof. This flange under the platform can be constructed from a single piece of material with a plurality of holes incorporated therein., making it consequently lightweight and easy to install. Yet another aspect of the present invention is to provide an airtight seal between the vertical tube and the hydrant holder. When the vertical tube is interrelated with the hydrant holder, a series of seals can be used where the tightening of at least one bolt increases the compression in an intermediate seal, pressing it tightly between the vertical tube and the internal diameter of the support. hydrant As alluded to above, the sealing system can be improved by the use of a sleeve that covers the seals and that interrelates with the vertical tube and the external diameter of the hydrant holder. The Summary of the Invention is not intended and should not be construed as representative of the full scope and scope of the present invention. The present invention is established at various levels of detail in the Summary of the Invention as well as in the accompanying drawings and the Detailed Description of the Invention and is not intended to limit the scope of the present invention either by inclusion or not. inclusion of elements, components, etc. in this Summary of the Invention.

In certain cases, details that are not necessary for an understanding of the invention, or that return to other details that are difficult to perceive, may have been omitted. It should be understood, of course, that the invention is not necessarily limited to the particular embodiments illustrated herein. Referring now to Figures 1-12, a mounting system is provided to secure a hydrant 2 to a roof platform 6. More specifically, the embodiments of the present invention are used with a common hydrant 2 having a vertical tube 10 leading to a water supply 14. In the illustrated embodiment, the vertical tube 10 is optionally interconnected with a water supply 14 that is selectively opened by a handle 16 of the hydrant 2. A hydrant holder 18 provides rigidity to the vertical tube 10. In order to ensure that substantially no fluid infiltrates into the interior of the building, a seal assembly 84 is employed, which includes an upper well seal 86, an intermediate seal 94 and a lower seal 98, which interrelates with the vertical pipe 10 and the hydrant support 18. A sleeve 22 can also be included to further provide leakage resistance. Referring now to Figures 1-6, it is shown that the hydrant holder of one embodiment of the present invention includes a tube 26 and a flange 30. Although it is shown herein that the tube 26 and flange 30 have cross sections Generally circular, one skilled in the art will appreciate that any shaping of the tube 26 and flange 30 can be employed without departing from the scope of the invention. One purpose of the hydrant support 18 is to provide rigidity to the standpipe 14, thus avoiding the angular movements of the vertical tube 10 with respect to the roof platform 6. In order to prevent air, moisture and other external contaminants from entering the building between any voids that may exist between the vertical tube 10 and the tubular portion 26 of the hydrant holder 18, a sleeve 22 is provided. The sleeve 22 is placed in the vertical tube 10 and the tube 26 of the hydrant holder 18. The flange 30 of the hydrant holder 18 includes a plurality of openings 34 defining a pattern of holes for the reception of mounting bolts 38, which help to ensure a rigid interconnection between the hydrant holder 18 and the roof platform 6. With specific reference to Figures 3 and 4, the interconnection of the hydrant holder 18 is preferably achieved by the plurality of mounting bolts 38 which are placed through the openings 34 of the flange 30, through the platform 6 of roof and a lower face 42 of the roof (which may include a plurality of corrugations) and through a flange 46 under the platform. The roof platform 6 and the lower face 42 of the roof in this manner are interposed between the flange 30 of the hydrant holder 18 and the flange 46 under the platform and held in place by a plurality of nuts 50 which are interconnected to the mounting bolts 38. As will be described in. Further detail in the following, after the hydrant holder 18 interconnects with the roof platform 6, the vertical pipe 10 and associated hydrant 2 are placed within an internal diameter of the pipe 26 and interconnected to the water supply 14. The sleeve may also be associated with the vertical tube 10, thereby obstructing any gaps between the vertical tube 10 and the tube 26. Referring now to Figure 5, various views of the alternative interconnection schemes are shown. More specifically, one skilled in the art will appreciate that, although a tube 26 interconnected to a flange 30 is shown in a vertical position, other methods of interconnection may be contemplated by embodiments of the present invention. For example, as shown in Figure 5A, the tube is completely omitted, where the vertical tube 10 is associated with the flange 30 and the flange 46 under the platform. This interconnection scheme makes possible an added stability to the vertical tube 10 since it is held in at least two positions. However, the added benefit of the tube is omitted, thereby reducing the stability of the hydrant, unlike that shown in Figure 3. One skilled in the art will appreciate that various seals can also be included with the tabs 30 and 46 to reduce the odds of leakage. Referring now to Figure 5B, another method for interconnecting the hydrant assembly to a roof platform 6 is shown. Here, the system of Figure 3 is reversed, where the tube 26 is placed inside the ceiling. The remainder of the assembly is similar to that shown in Figure 3, where the flange 46 under the platform is used together with a flange 30 of the hydrant holder to provide the structure necessary to hold the riser in place. Also included is seal assembly 84, which interconnects the tube to vertical tube 10. Referring now to Figure 5C, yet another method of interconnection is shown which is very similar to that of Figure 5B. More specifically, in this configuration, the flange under the platform is omitted wherein the seal assembly 84 provides most of the structural support to the standpipe 10. Referring now to FIG. 5D, yet another method of interconnection is shown, in FIG. where an elongated tube is provided. The tube 26 is designed to extend above the roof platform 6 and below the lower face 42 of the roof. However, one skilled in the art will appreciate that the tube 26 can extend only in one direction. The tube 26 is held in place by the flange 30 and the flange 46 under the platform, which are interconnected by a plurality of mounting bolts 38 and associated nuts 50. The vertical tube 10 is fixed inside the tube 26 by at least one seal assembly 84. Here it is shown that the flange 30 and the tube 26 are separable elements. This concept can be continued to the modality shown in Figure 3 as well. In addition, one skilled in the art will appreciate that the seal assembly 84, the tube 26, the flange 30 and the flange 46 under the platform in any of the embodiments contemplated herein may be made from one or more parts, such as a configuration in clam shell that can be used with sealing elements such as o-rings to facilitate assembly. Referring now specifically to Figures 6 and 7, the flange 30 of the hydrant holder and the flange 46 are shown under the platform. More specifically, of some embodiments thus also of the present invention, the flange 30 employs a plurality of opgs 34 of about 1,905 cm (3/4 inch) in diameter, placed approximately in a 20.32 cm (8 inch) bolt circle. ). One skilled in the art will appreciate, however, that the flange 30 can have any shape, be of any size and have opgs of any size and number. In addition, each opg 34 may be associated with a slot 54 that allows adjustments of the hydrant holder 18 prior to the rigid interconnection of the hydrant holder 18 with the roof platform 6. Preferably, the flange 30 employs countersunk hexagonal holes which allow an individual installer to butt the flange 46 under the platform with the mounting bolts 38, without having to secure the heads of the mounting bolts at the same time. The flange 46 under the platform may include a plurality of weight reducing spaces 58 that allow easier interconnection to the mounting bolts 38. The flange 46 under the platform may also include a plurality of grooves 54 to allow rotational alignment of the flange 46 under the platform with respect to the flange 30 of the hydrant holder. As will be appreciated by someone skilled in the art, the flange 46 under the platform can be omitted where the nuts 50 interrelate with the mounting bolts 38 and engage the lower face 42 of the roof. Referring now to Figure 8, there is shown an exploded perspective view of the hydrant holder 18 of one embodiment of the present invention. Here, the hydrant holder 18 includes the hollow cylindrical tube 26 interconnected to the flange 30 having four opgs 34 in an orifice pattern previously described. The hydrant support 18 is preferably constructed of cast iron, however, it is contemplated that other similar rigid materials may be employed without departing from the scope of the invention. According to embodiments of the present invention, the tube is preferably about 28.575 centimeters (11.25 inches) long and the flange has a diameter of about 25.4 centimeters (10 inches). Again, those skilled in the art will appreciate that the tube and flange can be of any size. When the flange 30 is interconnected to the roof platform 6, a wedge 62 may be employed, which may also include slotted apertures 54, to help ensure that the tube 26 is oriented generally vertically. The wedge 62 preferably has an angle of approximately two degrees, however, it is foreseeable that wedges 62 of other angles can be used without departing from the scope of the invention. It is shown that the flange 46 under the platform has a plurality of spaces 58 to decrease its weight. The flange 46 beneath the platform may also include a shoulder 66 emanating from there, which provides a location for a plurality of screws 70. In operation, the screws 70 interrelate with the vertical tube 10 to enhance the angular and vertical rigidity. As someone skilled in the technique will appreciate, a plurality of washers 74, lock washers 78 and nuts 50 is used together with the mounting bolts 38. Referring now to Figures 9 and 10, the sleeve 22 and associated hardware material, used to connect the sleeve 22 to the hydrant holder 18, is provided. More specifically, the sleeve 22 of the embodiments of the present invention includes a cylindrical portion 82 associated with the vertical tube 10, and a larger diameter portion associated with the tube 26 of the hydrant holder 18. As shown herein, the sleeve 22 is comprised of a plurality of circumferential and / or conical sections, however, one skilled in the art will appreciate that the sleeve may include various interconnected individual pieces and may be of any shape that generally avoids Fluids or other elements enter between the vertical tube 10 and the tube 26. Preferably, the sleeve is made of EPDM and has at least some ultraviolet protection, thereby maximizing the life of the sleeve material. Referring now to Figures 11 and 12, another embodiment of the sleeve is shown. As one skilled in the art will appreciate, the sleeves, as contemplated herein, can be configured in a variety of shapes and sizes. Here, the sleeve 22 is similar to that described in the foregoing, however it is described more concisely as a cap that locks the seal assembly. The sleeve assembly, as described in greater detail in the following, is also very similar to that described in the foregoing. With specific reference to Figure 12, the concept of a multi-piece sleeve is shown. Here, the sleeve is comprised of two detachable parts that close like clam shell around the vertical tube 10 and interconnect. The interconnection can be achieved by adhesives, fasteners, a snap fit (which can be integrally molded into the sleeve halves), tie-downs or any other similar method. One skilled in the art will appreciate that the sleeve may be comprised of two or more pieces, thereby facilitating the interconnection of the sleeve 22 to the hydrant assembly in the field. As shown in Figure 10, the embodiments of the present invention employ an upper well seal 86 having a flange 90 for interconnection with the upper end of the tube 26. Below the upper well seal 86, it is preferably located a rubber seal 94 that is followed by a lower well seal 98. The lower well seal 98 also includes a threaded inner diameter, such that a bolt 102 is used to interconnect the three seals. The upper cylindrical portion 82 of the sleeve 22 then slides down over the seal assembly to terminate the sealing system. The remaining portion of the sleeve 22 then covers the bolts 102 and seals and couples the tube 26. In this manner, a system is provided where fluids, air, smoke or other external contaminants are prevented from infiltrating into the space between the tube 26 of the hydrant support 18. Referring now again to Figures 1-12, the roof mounting system of the embodiments of the present invention is shipped in equipment that preferably includes a pre-assembled hydrant assembly, with seal assembly and sleeve 22 interconnected thereto, together with the support 18 of hydrant and associated hardware material. Alternatively, the equipment may include only the seal assembly 84, hydrant holder 18, sleeve 22, and associated hardware to accommodate existing hydrant assemblies. To install the hydrant holder 18 of one embodiment, the hole pattern of the flange 30 of the hydrant holder is initially used to provide locations for piercing the holes of the mounting bolts 38, through the roof platform 6 and the lower face 42 of the roof. The tube 26 of the hydrant holder is also used to locate the penetration of the vertical tube. More specifically, the installer places the hydrant holder 18 on top of the roof platform 6 and assesses the need for any wedging. If wedging is indeed required, the appropriate wedge (s) may be placed on the roof platform 6 together with the hydrant holder to ensure that the hydrant holder 18 will generally be aligned vertically after installation. Next, the location of the mounting holes and the hole accommodating the standpipe 10 are marked. The associated hydrant stand and associated wedges 62 are then removed and the appropriate holes are drilled into the roof deck 6 and through the roof. roof platform below the surface 42. The hydrant holder 18 and associated wedges 62 are then placed over the hole and a plurality of mounting bolts 38 are then threaded through the openings of the flange 30, through the openings any wedges included, through the roof platform 6 and through the lower face 42 of the roof platform. The flange 46 under the platform is then carried and interconnected to the mounting bolts 38 by a plurality of washers 70 and 74 and nuts 50. Finally, a plurality of screws 70 is used which interrelates with the threaded holes in the shoulder 66. which projects from the flange 46 under the platform, generally avoiding consequently the rotation and displacement of the vertical tube. Instead of screws 70, another seal assembly 84 can be used to interconnect vertical tube 10 with projection 66, or a clamp or bracket can be employed to interconnect vertical tube 10 with flange 46 under the platform. For example, a split ring with or without seals is contemplated. After the hydrant holder 18 is located, the installer inserts the vertical tube 10 (with the associated seal assembly 84 positioned towards the hydrant 2) through the tube 26 of the hydrant holder 18. The upper well seal 86, rubber seal 94 and associated well seal 98 then slide between the vertical tube 10 and the hydrant holder 18. One skilled in the art will appreciate that seal assembly 84 can alternatively be clamped like clam shell around vertical tube 10 to facilitate interconnection and adequacy at the site. It is important to note that the amount of vertical tube 10 exposed outside the hydrant holder 18 can be selectively altered in the vertical direction at this time. Once the desired height of the hydrant 2 is achieved, the other end of the vertical tube 10 is interconnected to the water supply 14. The seal assembly 84, which includes the upper well seal 86, the rubber seal 94, and the lower well seal 98, is then tightened by the bolts 102 such that the lower well seal 98 is pulled upwardly. towards the upper well seal 86, thereby bulging the rubber seal 94 to form an airtight seal between the vertical tube 10 and the tube 26.

At this time, the roofing material can be integrated around the hydrant holder 18. For example, a shelter, an insulating protection against the weather, used to prevent the intrusion of water into the buildings, can be wound around the tube 26 of the hydrant support 18. The roof window is often placed around discontinuities or objects that project from the roof of a building to divert water away from seams or joints. Here, one skilled in the art will appreciate that all sealing methods generally used to accommodate other roof protrusions can be used in conjunction with embodiments of the present invention. The optional sleeve 22, which was previously located near the hydrant 2, then slides on the vertical tube 10 and is associated with the tubular portion of the hydrant holder 18. The sleeves 22 of alternative embodiments having multiple pieces, of course, can be integrated on the hydrant holder 18 at any time. Some sleeves 22 contemplated herein are designed to be easily moveable away from the hydrant holder 18 or removed from the hydrant holder 18, to allow selective access to the bolts 102 of the seal assembly, thereby allowing quick access to the assembly 84. of seal for repairs and / or replacement. Finally, the vertical tube 10 interconnects the hydrant 2 at one end and the water supply 14 at the other end. Although various embodiments of the present invention have been described in detail, it is apparent that modifications and alterations of those embodiments will occur to those skilled in the art. However, it should be expressly understood that such modifications and alterations are within the scope and spirit of the present invention, as set forth in the following claims.
