Abstract

A sprinkler wedge designed for inhibiting water discharge from an open or activated sprinkler head. The sprinkler wedge generally comprises a main body having proximal and distal ends. A handle assembly connected toward the proximal end for easy grasping by a human hand, and a forked tip toward the distal end. The sprinkler wedge is designed for improved single-handed insertion into the water stream of an activated sprinkler head.

Claims

1. A sprinkler wedge comprising:

a basically unitary main body having a distal and proximal end and a length therebetween, the main body having a generally wedge shape with the larger portion of the wedge toward said proximal end;

a handle assembly attached at said proximal end of said main body;

a forked tip arranged toward said distal end of said main body, said forked tip including at least two tines and a space therebetween; and

a groove arranged on a top surface of said main body;

wherein said main body is sized and shaped to pass through a central opening of a fire sprinkler head between two frame arms;

and wherein said forked tip and said groove are immobile relative to each other.

2. The sprinkler wedge of claim 1 wherein said top surface has a convex shape.

3. The sprinkler wedge of claim 2 wherein a base of said wedge is flat.

4. The sprinkler wedge of claim 1 wherein said handle assembly comprises a handle arranged perpendicular to said length of said main body and a neck connecting said handle to said main body.

5. The sprinkler wedge of claim 4 wherein said handle is cylindrical in shape.

6. The sprinkler wedge of claim 4 wherein a reinforcing bar is placed interior to said handle, said neck and said main body.

7. The sprinkler wedge of claim 1 wherein said groove is sized and shaped to slide over a screw head of a screw connecting a deflector plate to said two frame arms.

10. The sprinkler wedge of claim 1 wherein the sprinkler wedge is comprised of rubber.

11. The sprinkler wedge of claim 10 wherein the elastic properties of said rubber allow the wedge to form a tight seal with the sprinkler head discharge port.

8. A method of inhibiting water flow from an open sprinkler head, the method comprising:

providing a sprinkler head having a water stream exiting a discharge port and impacting a deflector plate;

providing a sprinkler wedge, said wedge including;

a basically unitary wedge shaped main body;

a handle assembly at a proximal end of said main body;

a forked tip at a distal end of said main body, said forked tip including at least two tines with a space therebetween; and

a groove arranged on a top surface of said main body;

wherein said forked tip and said groove are immobile relative to each other;

grasping said handle;

placing said forked tip at said sprinkler head such that said water stream passes between said tines;

pushing said main body into said water stream until said main body is stably in contact with said sprinkler head and said water stream is at least partially blocked by said wedge.

9. The method of claim 8 wherein in said step of pushing, said groove passes over a screw head in said sprinkler head.
