FOR CONNECTING THE SAME TO A PIPE

FIELD

[0001] The present disclosure generally relates to sprinkler heads for fluid distribution systems and, more particularly, relates to sprinklers heads and adapter assemblies for connecting the sprinkler heads to fluid distribution systems.

BACKGROUND

[0002] For over a century, fluid distribution systems have increased occupant safety by providing fire protection to a variety of structures. These systems typically contain a fluid source, often under pressure, from which fluid may be drawn and distributed to one or more outlets in order to extinguish or otherwise control a potential fire. Fluid distribution outlets typical include a sprinkler head from which fluid is released, often through a diffuser that diffuses released fluid across a specified area. While the most prevalent uses of fluid distribution systems have historically been in commercial contexts, such as in factories, hotels, and office buildings, where the systems are often mandated by local building codes or insurance considerations, use of fluid distribution systems in residential contexts is becoming more commonplace. This trend is likely to continue as more state and local regulators amend construction codes to mandate installation of such systems in new residential construction.

[0003] Sprinkler heads may fail, age, or otherwise become obsolete. Due in part to variety of sprinkler head and outlet designs, installing, replacing, repairing, or upgrading sprinkler heads or components may be tedious and require undue man hours For example, it may become necessary to replace or upgrade sealing components in an aging fluid distribution system due to increased pressure after the system ^' s fluid source is recharged.

The features illustrated or described in connection with one non-limiting embodiment may be combined with the features of other non-limiting embodiments. Such modifications and variations are intended to be included within the scope of the present disclosure.

[0021] In one embodiment, referring to Figs. 1-15, an adapter assembly or kit

10 can be used to attach a sprinkler head 12 or a fire sprinkler head, such as a non- threaded, flange-type sprinkler head, for example, to a pipe 14 of a fluid distribution system, to another portion of a fluid distribution system, or to another suitable system. In other embodiments, the sprinkler head 12 can comprise a standard sprinkler head comprising a male threaded portion and a separate flange comprising a female threaded portion. The flange can be threadably engaged with the standard sprinkler head to form a flange-type sprinkler head assembly or sprinkler head. The term "fluid" can comprise liquids, foams, slurries, plasmas, and/or gases. In one embodiment, the adapter assembly or kit 10 can comprise an adapter ring 16 (see e.g., Figs. 9-15) and a sealing member. The adapter ring 16 can define an internal bore 20 configured to receive a portion of the sprinkler head 12 therethrough and a wall 22 at least partially

surrounding the internal bore 20. In one embodiment, the wall 22 can comprise a threaded portion 24 configured to be at least partially engaged with a threaded end 25 of the pipe 14, for example, in various embodiments, the threaded end 25 of the pipe 14 can form a male end with threads 27 formed on its outer surface (see e.g., Fig. 25). In one embodiment, the adapter ring 16 can comprise an outer wall or first wall 26 comprising a gripping surface configured to be used to tighten or hand tighten the adapter ring 16 onto the threaded end 25 of the pipe 14.

[0022] In one embodiment, referring to Figs. 1-8 and 21-23, the adapter assembly 10 can comprise a sealing member 30. The sealing member 30 can comprise a gasket, an o-ring, a polytetrafluoroethylene "PTFE" ring, and/or other suitable sealing members configured to create a fluid-tight seal between a portion of the sprinkler head 12 and the pipe 14. In one embodiment, the sealing member 30 can be positioned within a recess, groove, and/or a slot on the end of the pipe 14 and/or within a recess, groove, and/or slot in a flange of the sprinkler head 12. In other embodiments, the sealing member 30 can be formed with or attached to the end of the pipe 14 or the flange of the sprinkler head 12. In certain embodiments, a sealing surface on the end of the pipe 14 and/or the flange of the sprinkler head 12 can be used in place of the sealing member 30, for example. In one embodiment, thread paste sealant (a.k.a., "pipe dope"), PTFE tape, and/or other suitable sealing compounds, tapes, and/or members are not generally needed to be placed around and/or on the threaded end 25 of the pipe 14 and/or the threaded portion 24 of the adapter ring 16 owing to the fluid-tight sea] created by the sealing member 30 when positioned intermediate the end of the pipe 14 and the flange of the sprinkler head 12.

[0023] In one embodiment, referring to Figs. 1 -5, 7-12, 14, and 15, the adapter ring 16 can comprise a first surface 17 and a second surface 19. The threaded portion 24 can be positioned intermediate the first surface 17 and the second surface 19. A groove 21 can be defined in the adapter ring 16.

In other various embodiments, the groove 21 can be defined at least partially in the wall 22. For example, in one embodiment, the groove 21 is defined in the wall 22 and comprises a lip configured to compressingly engage an opposing surface of a portion of the flange of the sprinkler head 12 or other portion of the sprinkler head.

[0024] In one embodiment, referring to Figs. 1 -8 and 16-20, the sprinkler head

12 can comprise a first end 32 and a second end 34. The first end 32 can comprise a flange 37 configured to be engaged with a portion of the adapter ring 16 and the second end 34 can comprise a fluid or water diffuser 36 configured to dispense a fluid or water. In one embodiment, the flange 37 can comprise the sealing member 30 or, in other embodiments, can comprise a sealing surface configured to create a fluid-tight seal with an end of the pipe 14. The sprinkler head 12, including the flange 37, can define a bore 35 at least partially therethrough configured to allow fluid to pass from the pipe 14 to the fluid or water diffuser 36. The bore 35 can be surrounded by a recess 39 configured to receive a raised portion of the pipe 14, as discussed herein, to align the sprinkler head 12 with the pipe 14 and align the bore 35 with an internal bore of the pipe 14. The sprinkler head 12 can also comprise a body 38 comprising a fluid activation portion, such as a temperature sensitive fluid activation portion, for example, configured to detect the presence of a condition in need of activation of the sprinkler head 12, such as a fire, for example. In one embodiment, the sprinkler heads of the present disclosure can comprise fire sprinkler heads.

[0025] In one embodiment, referring to Figs. 16-18, the flange 37 of the sprinkler head 12 can comprise a first portion 39 comprising a first diameter or perimeter and a second portion 41 comprising a second diameter or perimeter. In various embodiments, the first diameter or perimeter can be larger than the second diameter or perimeter. In such an embodiment, the first portion 39 and/or the second portion 41 can be used to align and/or center the sprinkler head 12 with features of the adapter ring 16, or another adapter ring, and features of the pipe 14, or another pipe.

[0026] In one embodiment, as discussed above, the sprinkler head 12 can be formed of more than one component. In such an embodiment, a flange can comprise a threaded portion, such as a female threaded portion, and a standard sprinkler head can comprise a threaded portion, such as a male threaded portion. The flange can be threadably engaged with the sprinkler head to form a flange-type sprinkler head suitable for use with the adapter assemblies of the present disclosure. In other embodiments, the flange can be otherwise attached to a standard sprinkler head as will be recognized by those of ordinary skill in the art.

[0027] In one embodiment, referring to Figs. 24-26, the threads 27 of the threaded end 25 of the pipe 14 can comprise any standard threading, such as a National Pipe Thread (NPT), for example, or can comprise non-standing threading. A connection end 44 of the pipe 14 can be attached in any suitable manner to the fluid distribution system, such as through the use of an adapter, welding, threading, solvent cementing, and/or other suitable connection methods known to those of skill in the art. The pipe 14 can comprise an internal bore 46, a raised portion 48 surrounding the internal bore 46, and recess 50 configured to receive the sealing member 30. In one embodiment, the raised portion 48 of the pipe 14 can be engaged with the recess 39 of the sprinkler head 12 when the sprinkler head 12 is attached to the pipe 14 to align the internal bore 46 of the pipe 14 with the bore 35 of the sprinkler head 12. The fluid of the fluid distribution system can be present in the internal bore 46 before the sprinkler head 12 is activated and can flow through the internal bore 46 when the sprinkler head 12 is activated to supply the fluid to the bore 35 of the sprinkler head 12 for dispersion. The recess 50 can be positioned radially outwardly from the raised portion 48 and can be configured to accept a portion of the sealing member 30 such that the sealing member 30 can be compressed between the end of the pipe 14 and a portion of the flange 37 of the sprinkler head 12 to create a fluid-tight seal between the sprinkler head 12 and the pipe 14.

[0028] In one embodiment, referring to Figs. 1 -3, to assemble or connect the sprinkler head 12 to the pipe 14, the sealing member 30 can be placed into the recess 50 of the pipe 14 and/or into a recess, groove, and/or slot in the flange 37 of the sprinkler head 12. In other embodiments, the sealing member 30 can be placed on the end of the pipe 14 and/or on the flange 37 of the sprinkler head 12. Next, in various

embodiments, the adapter ring 16 can be partially threaded and/or screwed onto the pipe 14. As such, the threaded portion 24 of the adapter ring 16 can be threadably engaged with the threaded end 25 of the pipe 14. At this step, the adapter ring 16 may not be fully tightened onto the pipe 14. In such an embodiment, the threadable connection between the pipe 14 and the adapter ring 16 may not form a fluid-tight seal, but instead, may be used to retain the adapter ring 16 to the pipe 14. The flange 37 of the sprinkler head 12 or other portion of the sprinkler head 12 can then be slidably inserted into the groove 21 , such that the bore 35 of the sprinkler head 12 can be positioned in alignment with or in fluid communication with the internal bore 46 of the pipe 12. When the sprinkler head 12 is in such a position, fluid from the pipe 14 of the fluid distribution system can flow through the internal bore 46 of the pipe 14, pass through the bore 3 in the sprinkler head 12, and be provided to the fluid or water diffuser 6 for distribution. After the sprinkler head 12 is in position within the groove 21 , the adapter ring 16 can be further tightened to thereby compress the sealing member 30 between a portion of the flange 37 and the end of the pipe 14 and create a fluid-tight seal between the end of the pipe 14 and the sprinkler head 12. As illustrated in the figures, the threaded end 25 of the pipe 14 and the threaded portion 24 of the adapter ring 16 may form a complimentary seal to the sealing member 30 or may not form a seal at all and may merely be used to retain the adapter ring 16, and thereby the sprinkler head 12, to the pipe 14.

(0029) In the embodiments below, like numbers can denote like elements (e.g.,

16, 1 16, 216, 316, 416 etc.)

The adapter ring 416 can define an internal bore 420 surrounded by a wall 422. The wall 422 can comprise a threaded portion 424. The adapter ring 416 can be used to threadably engage a threaded end 425 of a pipe 414. An end of the pipe 4 4 can have a recess, such as recess 50, for example, formed therein which is configured to at least partially accept the sealing member 430. The sprinkler head 412 can be similar to or the same as the sprinkler head 12 discussed above.

[0033] In one embodiment, still referring to Figs. 38-42, to install the sprinkler head 412 to the pipe 414, the sprinkler head 412 can be inserted into the internal bore 420 of the adapter ring 416 such that a surface of the flange 437 portion rests against a surface of the adapter ring 416. The adapter ring 416 can then be threadably engaged with the threaded end 425 of the pipe 414, thereby engaging the threaded portion 424 with the threaded end 425. By tightening the connection between the threaded portion 424 and the threaded end 425, the sealing member 430 can be compressed between the end of the pipe 414 and a portion of the flange 437 to create a fluid-tight seal. In such an embodiment, the threaded portion 424 and the threaded end 425 may οτ may not form a fluid-tight seal when tightened.

[0034] In one embodiment, the flange 437 can be formed integral with the sprinkler head 412 or can be a separate component from the sprinkler head 412. In an embodiment in which the sprinkler head 412 is a separate component from the flange 437, the sprinkler head 412 can comprise a male threaded portion and the flange 437 can comprise a female threaded portion such that the sprinkler head 412 can be threadably engaged with the flange 437. In other embodiments, the flange 437 can comprise a male threaded portion and the sprinkler head 412 can comprise a female threaded portion, for example. In one embodiment, the threaded portions of the sprinkler head 412 and the flange 437 can comprise NPT threads or other suitable threads, for example.

[0035] In one embodiment, referring to Fig. 43, an adapter ring 516 of an adapter assembly can comprise a centering recess 551 and a centering wall 553.
