Abstract

A sprinkler head assembly having a sprinkler head with a through bore is coupled to a coupling member having a bore in fluid communication with said through bore of said sprinkler head. One of said sprinkler head and coupling member fits within the other. A groove is formed on the inner member for receiving a portion of a set pin slidingly engaged within the outer member. A seal between the inner and outer member provides a fluid-tight connection.

Claims

1. A sprinkler head assembly comprising:

a sprinkler head having a through bore;

a coupling member having a bore in fluid communication with said through bore of said sprinkler head, said coupling member further having an inner surface;

said sprinkler head having a skirt and including a groove formed in said skirt;

said skirt sized to fit within said bore; and

a set pin located transversely of said bore and engageable with said groove when said sprinkler head skirt is located within said bore.

2. The sprinkler head assembly according to claim 1, wherein said set pin is movable between a first and a second position.

3. The sprinkler head assembly according to claim 1 further comprising a seal for sealing said sprinkler head and said coupling member, said seal located in said inner surface of said coupling member.

4. The sprinkler head assembly according to claim 3 wherein said seal comprises a gasket located in said inner surface of said coupling member.

5. The sprinkler head assembly according to claim 1 wherein said coupling member further includes a through bore intersecting said bore of said coupling member.

6. The sprinkler head assembly according to claim 5 wherein said coupling member further includes means for joining said coupling member to at least one pipe section.

7. A sprinkle head assembly comprising:

a sprinkler head having a through bore and an inner surface;

a coupling member having a bore fluidly engaged with said through bore of said sprinkler head, said coupling member having an outer skirt and including a groove formed in said skirt, said outer skirt sized to fit within said sprinkler head through bore; and

a set pin located transversely of said sprinkler head through bore and engageable with said groove when said coupling member skirt is located within said sprinkler head through bore.

8. The sprinkler head assembly according to claim 7, wherein said set pin is movable between a first and a second position.

9. The sprinkler head assembly according to claim 7 further comprising a seal for sealing said sprinkler head and said coupling member, said seal located in said inner surface of said sprinkler head.

10. The sprinkler head assembly according to claim 9 wherein said seal comprises a gasket located in said inner surface of said sprinkler head.

11. The sprinkler head assembly according to claim 7 wherein said coupling member further includes a through bore intersecting said bore of said coupling member.

12. The sprinkler head assembly according to claim 11 wherein said coupling member further includes means for joining said coupling member to at least one pipe section.
