Push on/pull off protective cap for fire protection sprinklers
A protective cover for a fire protection sprinkler includes a pair of sidewalls and an orthogonal wall structure connected to an upper edge of each of the pair of sidewalls. The orthogonal wall structure including a slot therein that opens along an edge of the orthogonal wall structure in alignment with an opening between the pair of sidewalls. The slot including a pair of side edges including a pair of opposing arcuate regions adapted to engage a deflector mounting boss of a fire protection sprinkler. An arcuate sidewall extends from the orthogonal wall structure and an upper wall extending inward from an upper edge of the arcuate sidewall and opposing the orthogonal wall structure to define a cavity that is adapted for receiving a deflector of a fire protection sprinkler.
1. A protective cover for a fire protection sprinkler comprising:
a pair of sidewalls;
an orthogonal wall structure connected to an upper edge of each of the pair of sidewalls, said orthogonal wall structure including a slot therein that opens along an edge of the orthogonal wall structure in alignment with a side opening between the pair of sidewalls, the slot including a pair of side edges including a pair of opposing arcuate regions that engage a deflector mounting boss disposed between a deflector and an end of a pair of frame arms of a fire protection sprinkler;
an arcuate sidewall extending from said orthogonal wall structure: and an upper wall extending inward from an upper edge of the arcuate sidewalk the upper wall opposing and overlapping the orthogonal wall structure,
wherein the orthogonal wall structure, the arcuate sidewalk and the upper wall defining a cavity that receives the deflector of the fire protection sprinkler.
2. The protective cover according to claim 1 , wherein the pair of sidewalls each include opposing protruding portions on an inside thereof.
3. The protective cover according to claim 1 , wherein said pair of sidewalls each include a beveled guide wall along the side opening between the pair of sidewalls.
4. The protective cover according to claim 1 , wherein the pair of sidewalls each include a forward edge along the side opening between the pair of sidewalls and the pair of sidewalls each include a rear edge with a gap defined between the rear edges of the pair of sidewalls.
5. The protective cover according to claim 4 , wherein the orthogonal wall structure includes a web between the slot and the gap defined between the rear edges of the pair of sidewalls.
6. The protective cover according to claim 4 , wherein the pair of sidewalls each include a sloped bottom edge adjacent the rear edge.
7. The protective cover according to claim 1 , further comprising a grip extending from the upper wall.
8. A shipping cap for a fire protection sprinkler, comprising:
a pair of sidewalls;
a deflector receiving portion including an orthogonal wall structure connected to an upper edge of each of the pair of sidewalls, a sidewall extending from said orthogonal wall structure and an upper wall extending inward from an upper edge of the sidewall and opposing the orthogonal wall structure, the orthogonal wall structure, the sidewall and the upper wall defining a deflector cavity that laterally receives a deflector of a fire protection sprinkler, said orthogonal wall structure including a slot therein that engages a deflector mounting boss disposed between the deflector and an end of a pair of frame arms of the fire protection sprinkler and that opens along an edge of the orthogonal wall structure in alignment with a side opening between the pair of sidewalls.
9. The shipping cap according to claim 8 , wherein the pair of sidewalls each include opposing protruding portions on an inside thereof.
10. The shipping cap according to claim 8 , wherein said pair of sidewalls each include a beveled guide wall along the side opening between the pair of sidewalls.
11. The shipping cap according to claim 8 , wherein the pair of sidewalls each include a forward edge along the side opening between the pair of sidewalls and the pair of sidewalls each include a rear edge with a gap defined between the rear edges of the pair of sidewalls.
12. The shipping cap according to claim 11 , wherein the orthogonal wall structure includes a web between the slot and the gap defined between the rear edges of the pair of sidewalls.
13. The shipping cap according to claim 11 , wherein the pair of sidewalls each include a sloped bottom edge adjacent the rear edge.
14. The shipping cap according to claim 8 , wherein the slot includes a pair of side edges including a pair of opposing arcuate regions that engage the deflector mounting boss of the fire protection sprinkler.
15. The shipping cap according to claim 8 , further comprising a grip extending from the upper wall.
16. The shipping cap according to claim 8 , wherein the sidewall comprises a partially arcuate sidewall.
