Fire sprinkler system
First Claim
1. An over-head fire suppression system configured to disperse a stream of liquid water in a downward trajectory onto a coverage area, said system comprising:
- an elongated tubular supply line configured as a conduit to carry liquid water, said supply line having a longitudinal centerline, said supply line having right and left sides separated by a vertical plane passing through said longitudinal centerline,a plurality of side-discharge fire sprinklers coupled directly to said supply line, each said fire sprinkler receiving liquid water from said supply line, each said fire sprinkler including a deflector configured to disperse the liquid water in a jet stream having a downward trajectory over a non-circular coverage area defined by a major diameter and a shorter minor diameter, each said side-discharge fire sprinkler including a dedicated temperature-sensitive trigger that when activated permits the water to flow in a liquid spray from said side-discharge fire sprinkler only toward said side coverage area,said plurality of fire sprinklers arranged so that half of said fire sprinklers are disposed on said right side of said supply line and the other half of said fire sprinklers are disposed on left side of said supply line in alternating fashion such that every other said fire sprinkler is disposed on said right side of said supply line with the other said fire sprinklers disposed in interleaved fashion on said left side of said supply line, said fire sprinklers disposed on said right side of said supply line being spaced apart one from the next by a spacing distance (S), and said fire sprinklers disposed on said left side of said supply line being spaced apart one from the next by the same said spacing distance (S).

Abstract
A fire suppression system in which side-discharge fire sprinklers are fitted to opposite sides of a supply line and aimed so that their coverage areas point in opposite directions. The fire sprinklers are alternated on left and right-hand sides of the supply line, and are spaced apart at a consistent interval. Each fire sprinkler includes a deflector configured to disperse the outflow of water over a non-circular coverage area. When two supply lines are installed next to each other so that half of the sprinklers on one supply line point toward the other supply line, and vise versa, the fire sprinklers are staggered so that their respective coverage areas are interlaced in the intermediate space.

10. An over-head fire suppression system configured to disperse a stream of liquid water in a downward trajectory onto a coverage area, said system comprising:
-
a first elongated tubular supply line configured as a conduit to carry liquid water, said first supply line having a longitudinal centerline and right and left sides separated by a vertical plane passing through said longitudinal centerline, a plurality of side-discharge first fire sprinklers coupled directly to said right side of said first supply line, each said first fire sprinkler receiving a flow of fire-suppressing liquid water from said first supply line, each said first fire sprinkler including a deflector configured to disperse the flow of liquid water in a jet stream having a downward trajectory over a non-circular coverage area, each said first fire sprinkler being separated from the next adjacent said first fire sprinkler by a generally equal spacing distance (S), each said first fire sprinkler including a dedicated temperature-sensitive trigger that when activated permits the water to flow in a liquid spray from said first fire sprinkler only, a second elongated tubular supply line configured as a conduit to carry liquid water, said second supply line having a longitudinal centerline and right and left sides separated by a vertical plane passing through said longitudinal centerline, said second supply line disposed parallel to said first supply line with said left side of said second supply line facing toward said right side of said first supply line, a plurality of side-discharge second fire sprinklers coupled directly to said left side of said second supply line, each said second fire sprinkler receiving liquid water from said second supply line, each said second fire sprinkler including a deflector configured to disperse the liquid water in a downward trajectory over a non-circular coverage area, each said second fire sprinkler being separated from the next adjacent said second fire sprinkler by a generally equal spacing distance (S), each said second fire sprinkler including a dedicated temperature-sensitive trigger that when activated permits the water to flow in a liquid spray from said second fire sprinkler only, and said spacing distance (S) between said first fire sprinklers being generally equal to said spacing interval distance (S) between said second fire sprinklers, wherein each said first fire sprinkler is separated from the next adjacent said second fire sprinklers by a spacing interval (S/2) equal to half of said spacing distance (S), said non-circular coverage areas from said first fire sprinklers being interlaced between said non-circular coverage areas from said second fire sprinklers. - View Dependent Claims (11, 12)
