Flexible dry sprinkler
First Claim
1. A flexible dry sprinkler comprising:
- a flexible tube having a first end and a second end;
an inlet attached to the first end of the flexible tube, the inlet defining an inlet orifice operatively sealed by an inlet seal;
an outlet attached to the second end of the flexible tube, the outlet defining an outlet orifice operatively sealed by an outlet seal; and
a flexible linkage extending between the inlet and the outlet through the flexible tube, the flexible linkage constructed to operatively release the inlet seal responsive to axial translation of the flexible linkage from a first position to a second position,wherein the flexible linkage is supported by the outlet seal in the first position and wherein the flexible linkage is constructed to axially translate toward the outlet when the outlet seal is released.

Abstract
A fire sprinkler head (12) has a valve (42) with an X-brace latch (54), and includes a flexible conduit (14). A sprinkler nozzle (16) is secured to a first end of the flexible conduit (14). The sprinkler nozzle (16) includes a first fitting (28), a sprinkler orifice (20) and fusible element (22). A second fitting (40) is secured to the second end of the flexible conduit (14) and includes the valve (42). The valve (42) has a valve element (44) which is moveable from a latched position to an unlatched position. A flexible link (56) extends from the sprinkler nozzle (16) to the X-brace valve latch (54). Breaking of the fusible element (22) releases the flexible link (56) to move from the latched position to the unlatched position, releasing the valve (42) for flow there-through.
