Abstract
A device for protecting and installing a fire protection sprinkler. The protective device is embodied as a tubular cap that axially receives the sprinkler. The protection and installation device includes a wall with a stiffening element to facilitate the strength and rigidity of the device so that it can sufficiently transfer a torque to install the protected sprinkler.
Claims18
A protected fire protection sprinkler assembly comprising:
- a fire protection sprinkler including:
- a frame having 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, the frame including a pair of spaced apart frame arms disposed in a plane and extending axially from the body;
- a fluid deflector affixed to the pair of spaced apart frame arms and centered along the central sprinkler axis;
- and
- a thermally responsive trigger assembly aligned along the central sprinkler axis;
- and
- a protection and installation device axially engaged with the fire protection sprinkler including:
- a tubular body having a first end, a second end axially spaced from the first end, and a shielding wall between the first end and the second end and circumscribed about the fire protection sprinkler and the central sprinkler axis to define an internal void for housing the fire protection sprinkler;
- at least one internal gripping formation engaged with one of the pair of spaced apart frame arms;
- and
- at least one stiffening element disposed along the shielding wall, the at least one stiffening element at least partially radially circumscribed about the thermally responsive trigger assembly;
- wherein the at least one internal gripping formation includes a pair of ribs extending axially from the first end to the second end and radially inward from the shielding wall, the pair of ribs being angularly spaced from one another to define a channel of the gripping formation for receiving one of the pair of frame arms, the at least one stiffening element extending angularly about the trigger assembly between a first rib to a second rib in the pair of ribs outside the channel such that the tubular body does not deform under application of a hand torque.

A protective device for a fire protection sprinkler comprising:
- a tubular body having a first end defining an opening centered about a central axis for axially receiving the fire protection sprinkler, a second end centered about the central axis and axially spaced from the first end, the body defining an internal volume between the first end and the second end for housing a portion of the received sprinkler;
- at least one internal gripping portion of the tubular body for engaging a frame arm of the fire protection sprinkler;
- and
- a wall portion of the tubular body extending between the first end and the second end, the wall including at least one stiffening element partially circumscribed about the central axis;
- wherein the at least one gripping portion includes a pair of diametrically opposed gripping portions, each gripping portion defining a channel for receiving a frame arm, the at least one stiffening element extending angularly between the gripping portions outside the channel;
- wherein each of the gripping portion includes a pair of ribs extending axially from the first end to the second end and radially inward from the wall portion, the pair of ribs being angularly spaced from one another to define the channel, the at least one stiffening element extending from one rib of one gripping portion to a rib of another gripping portion such that the tubular body does not deform under application of a hand torque.
