| 20080230238 | Mounting Coupling For Sprinkler Support System - A mounting coupling for a fire sprinkler support system includes an adjustable opening for receiving a sprinkler reducer coupling that allows insertion of the sprinkler coupling into the mounting coupling with a sprinkler head assembled thereto. The mounting coupling can be securely engaged to the reducer coupling and fixed to a support bar of the sprinkler support system using a single fastener thereby providing improved installation and functionality. | 09-25-2008 |
| 20100236795 | Fire Protection Sprinkler - A fire protection sprinkler includes a sprinkler body having a fluid passage extending therethrough. A plug member disposed in the fluid passage. A heat responsive unit releasably secures the plug member in the fluid passage. A pair of frame arms extend from the sprinkler body. A deflector is mounted to the pair of frame arms and includes a peripheral edge including a plurality of slots extending radially inward from the peripheral edge. The plurality of slots include a pair of slots orthogonal to the pair of frame arms and the deflector includes a pair of apertures radially inward of the pair of slots and orthogonal to the pair of frame arms. The pair of apertures include an inner arcuate portion and a radially outwardly extending portion extending from the inner arcuate portion. | 09-23-2010 |
| 20110278026 | Sprinkler System With Rapid Installation - A fire protection system includes fire sprinklers having a male member of a quick-connect coupling. Corresponding female members of a quick-connect coupling are molded into plastic water pipe couplings forming a water supply and distribution system or, alternatively, threaded into metal pipe couplings. | 11-17-2011 |
| 20120090859 | SPRINKLER HEAD - A sprinkler head A has a main body including a pipe connection portion and a frame portion. In the frame portion, an outer circumferential surface protruding to the outside of the pipe connection portion is provided, and beam-like portions (inward flanges) with which a lever of a thermo-sensitive breakup portion engages and openings obtained by cutting off the outer circumferential surface from the side of the pipe connection portion to the beam-like portion are provided at opposite positions in the outer circumferential surface. Thereby, the weight of the frame portion can be largely reduced. Therefore, the weight of a sprinkler head is reduced, so that the weight load applied to the fire extinguishing system pipes in which a large number of sprinkler heads are installed can be reduced, and the work burden due to the weight load when the sprinkler heads are conveyed and installed in the fire extinguishing system pipes can also be reduced. | 04-19-2012 |
| 20150375024 | DRY VISOR INTENDED TO BE MOUNTED IN A FIRE PROTECTION INSTALLATION OF THE TYPE COMPRISING A NETWORK OF VACUUM SPRINKLERS - A dry visor intended to be mounted in a fire protection installation, of the type including a network of vacuum sprinklers. The visor includes an elongate body having, at one of its ends, a connecting piece for coupling to piping, the connecting piece including a first nozzle capable of making a connection between the visor and the piping. The visor includes a shutoff member for shutting off the first nozzle. The other end of the visor bears a sprinkler. A connection is provided between the shutoff member that shuts off the first nozzle and a shutoff member that shuts off the nozzle of the sprinkler. The connection is configured to move in such a way as to cause a shutting-off position of the shutoff member of the sprinkler nozzle to coincide with a shutting-off position of the shutoff member that shuts off the first nozzle. | 12-31-2015 |
| 20160030785 | CPVC SPRINKLER ASSEMBLY WITH SUPPORT MEMBER - A sprinkler assembly that includes a deflector assembly that translates with respect to the sprinkler frame upon actuation of the sprinkler from an unactuated state. The sprinkler frame includes a support member having an annular member spaced from the outlet to limit or control the axial translation of the deflector assembly relative to the outlet. Moreover, the annular member includes a region to support a closure assembly and thermally responsive trigger assembly under a fluid static load. A cover plate assembly includes a flexible annular wall to allow the cover plate assembly to be pushed on and held about the annular member of the sprinkler frame. | 02-04-2016 |
