Definitions

  • This invention generally relates to an integrated domestic water system and interior fire sprinkler system. More particularly it relates to an integrated residential domestic water and fire sprinkler system.
  • Dedicated sprinkler systems which are connected to large diameter water supply mains are known in the prior art. These water sprinkler systems may be characterized as "stagnant" water systems, in that the water flows within the system only when a sprinkler head is activated.
  • fire sprinkler networks To a large extent the expense caused by the duplicity of system components required by separate independent water distribution networks has limited the acceptance of fire sprinkler networks to commercial or multiuse residential applications.
  • a further limitation of present fire sprinkler systems is that they require regular inspections of system operability as it is critical that water under pressure be supplied to the various sprinkler assemblies. Typically this requires that the occupant occasionally inspect and verity valves, gauges, etc. for operability.
  • the integrated water distribution system according to the present invention is a "nonstagnant" water flow system which can meet the requirements of various plumbing codes and regulations.
  • the use of the plurality of multiport fitting each having a plurality of external nipples permits the use of small flexible conduit which facilitates assembly and installation.
  • the present invention is directed to an integrated water distribution system for supplying a building's domestic water needs and fire sprinkler systems requirements without the duplicity of having separate water distribution networks.
  • a nonstagnant water distribution system can provide water requirements for both domestic use and fire sprinkler use.
  • One aspect of the present invention provides a multiport fitting for overhead securement and for use with a heat sensitive sprinkler head for a fire sprinkler system.
  • Another aspect of the present invention provides a "self-checking" fire sprinkler system with which the occupant can easily verify sprinkler operability by accessing a plumbing fixture for use, as pressurized water at any fixture within the network ensures pressurized water at all the fire sprinklers.
  • Yet another aspect of the present invention provides a mounting assembly for securing the multiport fitting in its overhead position.
  • the integrated water distribution network includes a plurality of multiport fittings, each fitting being interconnected using flexible plastic conduit with at least one other fitting.
  • Each fitting has a plurality of water conduits each leading to a plurality of exterior nipples upon which the flexible plastic conduit may be secured.
  • Each water conduit when connected as described herein, allows fluid communication with integrated network.
  • FIGS. 1-4 An integrated water distribution system 10 for a building 12, such as a residential structure, is illustrated in FIGS. 1-4.
  • the system 10 includes a plurality of multiport fittings 14 interconnected with a plurality of flexible plastic conduit 16, 18.
  • the conduits include risers or water supply lines 16 which emanate from a supply manifold 20 which is connected to the house main 50 and runners 18 which traverse between the various multiport fittings 14 and plumbing fixtures 22,24,26.
  • Plumbing fixtures 22,24,26 are individually served by a routed flexible plastic conduit 30 and may include a water closet 22, tub, vanity sink 24, or kitchen sink 26.
  • Fire sprinkler heads 32 are coupled to each multiport fitting 14.
  • Additional plumbing connections or attachments such as valves, piping, expansion tanks, pipe fittings (elbows, tees, etc.) are all well known in the art of plumbing.
  • unidirectional flow valves and temperature activated sprinkler heads are also well known in the art of sprinkler system design and installation.
  • These additional components which may be needed to fully implement a functional water distribution system according to the present invention, are well known to those skilled in the art and are not shown in the exemplary environment of FIGS. 1-4.
  • Multiport sprinkler fitting 14 includes a body 34 having an interior cavity 36 and a plurality of through-bores or ports 38.
  • the interior cavity 36 includes a threaded surface 39 for threadedly receiving and securing a conventional sprinkler head 32.
  • sprinkler heads 32 may be occasionally removed for maintenance or service. It is intended that a variety of different sprinkler heads 32 may be used to implement the system 10 of the present invention. Selection of the specific sprinkler head 32 will be apparent to one skilled in the art.
  • Each multiport fitting 14 includes a plurality of ports 38, each port 38 having an external nipple portion 40.
  • Nipple portions 40 are relatively smooth bored and include an external profile (ribbing) 42 for engaging the flexible conduit 16, 18 as will be described hereinafter.
  • Each multiport fitting 14 is provided a support or hanging device 44 for attaching the multiport fitting 14 to a support member within the ceiling (or walls) of the structure 12 in which the system 10 is used.
  • the support device 44 may include a flange 46 having apertures 48 through which fasteners 50 are used to secure the multiport fitting 14 to the structure 12.
  • the multiport fitting 14 may include a hexagonal-shaped body 34 having a plurality of radiating nipple portions 40 which are offset to one side of the body 34.
  • a flange 46 may be used to secure the multiport fitting 14 to a structural member (joist, wall, etc.) of the building 12 as illustrated in FIG. 5.
  • the integrated water distribution system 10 includes a plurality of interconnected multiport fittings 14.
  • Each multiport fitting 14 is secured by an installer adjacent the ceiling with the support device 18.
  • the multiport fittings 14 are interconnected through flexible conduits 16, 18 which may be cut to length at the site during the installation process and which are flexible so as to allow the conduits 16, 18 to be manipulated by the installer around obstacles, etc.
  • the connection between the multiport fitting 14 and the conduits 16, 18 are press-type or "slip" connections, where the conduits 16, 18 are expanded by manually pressing the conduits 16, 18 onto the nipples 40 of the multiport fitting 14.
  • This connection approach of the flexible conduits 16, 18 with the multiport fittings 14 is inherently more time efficient than many other mechanical connections, especially those of rigid pipings.
  • a securement ring (not shown) may be utilized to secure the conduit 16, 18 to the nipple 40 of the multiport fitting 14.
  • the network 10 includes a plurality of feeder lines or water supply lines 16 which originate from a supply manifold 20, which is shown beneath the structure 12, though only for illustrative purposes.
  • the manifold 20 in turn is connected to the house main 50 in conventional manner.
  • the number of feeder lines 16 is determined through analysis of the water flow and pressure requirements of the system 10 as is appreciated by one skilled in the art.
  • the feeder lines 16 are illustrated as being directly connected to the multiport fittings 14. However, the feeder lines 16 may alternatively be connected along the length of a conduit 18 (such as through a tee fitting), if desired.
  • a particularly novel aspect of the present invention is that a plurality of feeder lines 16, each connected to the manifold 20, are used to supply the network of multiport fittings 14.
  • a "nonstagnant" water distribution system 10 is implemented.
  • the plumbing fixtures of the systems are illustrated as a water closet 22, a vanity sink 24, and a kitchen sink 26.
  • FIGS. 2-4 where a system 10 providing a distribution network for the domestic water needs and fire sprinkler requirements is illustrated.
  • This system 10 provides a nonstagnant water distribution system for supplying requirements for both the domestic and fire sprinkler water fixture by establishing water flow within essentially the entire system 10 during occupant use of a plumbing fixture 22,24,26.
  • the integrated water distribution network 10 illustrates the system flow during use of the kitchen sink 26. Water requirements for the sink 26 are provided by the entire network 10 through its associated multiport fittings 14, as illustrated by the flow arrows. In this manner, the water within the system 10 and between the multiport fittings 14 is in motion. While the flow rates of individual conduits 16, 18 may not be equal (and may be in directions other than as illustrated) there is some flow of water in the conduits 16, 18 between all of the multiport fittings during sink 26 use.
  • FIG. 3 illustrates the system 10 during occupant use of the water closet 22.
  • the flow arrows again depict the direction of water flow within the conduits 18 between the multiport fitting 14 and in the supply lines 16. The exact flow rate and direction of flow within a particular conduit 16, 18 may be determined with additional information, if necessary.
  • FIG. 3 again illustrates that the water within the conduits 16,18 is nonstagnant (in motion) during use of the Water closet 22.
  • FIG. 4 illustrates an additional benefit of invention according to the present invention.
  • a water sprinkler 32 is illustrated as having been activated. Water flow requirements for the sprinkler 32 are provided by the plurality of conduits 18 leading to the associated multiport fitting 14. In this manner, rather than a single large diameter conduit supplying water, a plurality of small diameter conduits 18 together supply the sprinkler 32.
  • the water supply for the fire sprinklers 32 which typically is plumbed using a single large diameter piping, is now provided by a plurality of smaller flexible conduits 16,18.
  • An important benefit provided by the present invention is a "self-checking" fire sprinkler system 10 which allows the occupant to verify the fire sprinkler system 10 operability by simply using one of the variety of plumbing fixtures 22,24,26. In this regard, the occupant is ensured that pressurized water is available to the various fire sprinklers 32 if water is output from any plumbing fixture 22,26,28 upon occupant demand.
