| 20080202773 | FIRE SPRINKLER - A fire sprinkler of the preferred embodiments includes a frame, a trigger, and a deflector. The frame defines a duct to exhaust the flow of a fire suppressing or extinguishing substance, and includes a fastener to fasten the frame to a supply line. The trigger blocks the flow of the fire suppressing or extinguishing substance through the duct during a first mode, and permits the flow of the fire suppressing or extinguishing substance during a second mode. The deflector redirects the flow of the fire suppressing or extinguishing substance into a coverage area. The deflector also at least partially shields the trigger from the dispersal of a fire suppressing or extinguishing substance from an adjacent fire sprinkler and prevents a failure of the trigger. | 08-28-2008 |
| 20090294140 | Fire Protection Sprinkler With Plastic Pip Cap - A sprinkler assembly includes a sprinkler body having a base and a frame extending from the base. The base has a passage extending therethrough defining an inlet and an outlet. A deflector is mounted to the frame and spaced from the outlet, which is configured to deflect fluid flowing from the outlet in a radial pattern. A trigger assembly extends between the frame and the base and is adapted to support a plug in the outlet and release the plug when a temperature associated with a fire condition is detected. The plug is made from plastic and can include a reinforcing insert. | 12-03-2009 |
| 20110272168 | FUSE TYPE SPRINKLER - A fuse type sprinkler has a body which is fastened to a drain pipe for spraying water through a drain formed inside, a valve of which an upper end is inserted into the drain of the body and to which a sealing unit is mounted along an upper end circumference to press and seal an inner surface of the drain, a frame which is fastened to the body to surround the valve and is provided with a hook on a lower end inner peripheral surface, a heat sensing unit which supports a lower end of the valve to allow an upper end of the valve to be inserted into the drain while being hooked by the hook of the frame, and is provided with a fuse which is separated from the frame to fall off when the fuse is fused by heat, and a deflector which is positioned inside the frame and falls off and is hung on the hook when the heat sensing unit is separated to distribute water sprayed through the drain. | 11-10-2011 |
| 20130240219 | Sprinkler Assembly For Attachment To A Piping System - A sprinkler assembly can utilize an adapter having straight threads and an internal sealing member therein to attach the sprinkler to a piping system. The sprinkler may include tapering threads that engage with the straight threads of the adapter and compress the sealing member therein to form a fluid-tight seal. A sprinkler assembly can utilize a fitting that is attached to an extension member containing the sprinkler. The fitting allows the sprinkler and extension member to be coupled to the piping system with a solvent weld. A sprinkler assembly can utilize an attachment system to couple a sprinkler attached to an extension member to a piping system. The attachment system can include a first fitting attached to the connection member, a second fitting attached to the piping system, and a clamping member to clamp the two fittings together. | 09-19-2013 |

| 20120285707 | SPRINKLER HEAD - A sprinkler head configured to prevent breakage of a disk spring due to application of an excessive load and hold the disk spring stably at a predetermined position is provided. | 11-15-2012 |
| 20130333903 | UPRIGHT, EARLY SUPPRESSION FAST RESPONSE SPRINKLER - An upright ESFR sprinkler includes a generally tubular body, at least one frame arm, a closure assembly, an unactuated heat responsive trigger assembly and a deflector assembly with a K-factor greater than 14, and preferably 16.8. The passageway extends between inlet and outlet openings. The closure assembly is positioned proximate the outlet so as to occlude the passageway with a Belleville seal. An ejection spring is coupled to the closure assembly. The heat responsive trigger assembly has a Response Time Index of 40 meter | 12-19-2013 |
