Abstract
A device and method for protecting and installing a fire protection sprinkler. The protective and installation device has two discrete protective members coupled to one another about the sprinkler by a releasable locking arrangement defined by a connection between the two discrete protective members. At least one of the members includes a torque assist portion for applying torque to the fire protection sprinkler and each of the members includes a deflector protection portion.
Claims24
A protected fire protection sprinkler assembly comprising:
- a fire protection sprinkler including a body having an inlet, an outlet, an internal passageway extending between the inlet and the outlet along a central sprinkler axis, and an external thread formed about the central sprinkler axis, a pair of spaced apart frame arms disposed in a plane and extending axially from the body and converging toward one another to form an apex along the central sprinkler axis and spaced axially from the outlet, a thermally responsive trigger disposed along the central sprinkler axis between the outlet and the apex, and a fluid deflector affixed to the apex, the fluid deflector having an outer perimeter that surrounds the apex;
- and
- a protective device disposed about the fire protection sprinkler, the protective device including a first protective member and second protective member opposed from one another about the plane to at least partially surround the thermally responsive trigger,
- wherein the first protective member and the second protective member are identical and each comprises an impervious wall having:
- a first end located between the outlet and the apex,
- a second end that surrounds the outer perimeter of the deflector,
- a pair of lateral torque assist surfaces contiguous with the pair of spaced apart frame arms,
- a pair of locking elements disposed between the first end and the second end, and
- a releasing segment proximate the second end and aligned with the pair of locking elements.
