Abstract

A concealable sprinkler head includes a frame having a body mountable to a fire suppression liquid source, a pair of frame arms and a pair of corresponding drop pins slidably engaged with a respective frame arm. A thermal trigger is supported within the sprinkler frame. A fluid deflector is secured to the drop pins and includes a generally horizontal surface. The drop pins extend substantially orthogonally from the horizontal surface. An inclined surface of the fluid deflector extends angularly upwardly from the horizontal surface. A concealing cup surrounds the frame arms. A cover plate is attached to the concealing cup, covering the distal end thereof, wherein the drop pins and the deflector are positioned within the concealing cup. The cover plate is removable from the concealing cup permitting the drop pins and the deflector to axially slide out of the concealing cup into an operational position.

First claim

We claim:

1 . A concealable sprinkler head in combination with a space:
the concealable sprinkler head comprising:
a sprinkler frame comprising:
a body mountable to a fire suppression liquid source, the body defining a proximal inlet, a distal outlet and an internal fire suppression liquid passageway extending therethrough;
a pair of frame arms axially extending away from the body;
a pair of corresponding drop pins each being slidably engaged with a respective frame arm;

a thermal trigger supported within the sprinkler frame and configured to support a sealing plug in a sealing position to seal the internal fire suppression liquid passageway and maintain the sprinkler head in a non-spraying state, wherein activation of the thermal trigger releases the sealing plug from the sealing position,
a directional fluid deflector secured to the pair of drop pins, the fluid deflector including a generally horizontal surface, the pair of drop pins extending substantially orthogonally from the horizontal surface, and an inclined surface extending angularly upwardly from the horizontal surface toward the sprinkler frame;
a concealing cup having a generally horizontal upper wall attached to, and horizontally outwardly projecting from, the body of the sprinkler frame, a skirting side wall extending axially distally therefrom, and an open base end, the pair of frame arms being positioned within the concealing cup; and
a cover plate attached to the concealing cup, covering the open distal end of the concealing cup and maintaining the sprinkler frame in a compressed, non-activated position, wherein the pair of drop pins and the deflector are positioned within the concealing cup, the cover plate being removable from the concealing cup at a predetermined temperature, permitting the pair of drop pins and the deflector to axially slide out of the concealing cup through the open distal end thereof into an extended operational position; and
the space comprising a ceiling and a glass containing partition wall or window within the space and oriented substantially perpendicularly to the ceiling; the concealable sprinkler head being mounted in the ceiling and positioned between approximately four inches and approximately twelve inches away from the glass containing partition wall or window.

2 . The concealable sprinkler head in combination with the space of claim 1 , wherein the sprinkler head is mounted such that a plane extending between the pair of frame arms is parallel to the glass containing partition wall or window and the inclined surface of the directional fluid deflector is further away from the glass containing partition wall or window than the generally horizontal surface, such that fire suppression liquid is deflectable onto the glass containing partition wall or window.

3 . The concealable sprinkler head in combination with the space of claim 1 , wherein the sprinkler head is mounted in a pendent position.

4 . The concealable sprinkler head in combination with the space of claim 3 , wherein the ceiling is generally planar, and the cover plate is positioned against, and substantially flush with, the ceiling when the cover plate is attached to the concealing cup.

5 . The concealable sprinkler head in combination with the space of claim 1 , wherein the sprinkler head is positioned between approximately six feet and approximately twelve feet apart from a neighboring sprinkler head.
