Fire sprinkler head paint cover

Abstract

An easily removable fire sprinkler head paint cover to be temporarily installed over and around a fire sprinkler head so as to prevent paint or other finishing materials from coming into contact with a fire sprinkler head and to allow for uniform and systematic painting or finishing of walls or ceilings in which fire sprinkler heads are installed.

Description

TECHNICAL FIELD[0001]This invention relates to the painting of surfaces having fire sprinkler heads installed therein, and more particularly, to the protection of fire sprinkler heads during painting operations.BACKGROUND AND SUMMARY OF THE INVENTION[0002]As is well known, city, state, and federal regulations mandate the use of automated fire sprinkler systems in public and private buildings. Modern automated fire sprinkler systems comprise fire sprinkler heads which are typically of two types. The first type comprises a fusible solder link that prevents a plug from releasing and dispersing pressurized water. The fusible solder link melts at a predetermined temperature which allows the plug to release the pressurized water and put out a fire. The second and most common type of fire sprinkler head comprises a glass vial that prevents a plug from releasing and dispersing pressurized water. The glass vial contains a chemical that expands at a predetermined temperature thereby breaking ...

AI Technical Summary

Benefits of technology

[0005]The present invention comprises a fire sprinkler head paint cover which overcomes the foregoing and other shortcomings long since associated with the prior art. In accordance with the broader aspects of the invention a fire sprinkler head paint cover comprises a dome which receives the operating instrumentalities of the fire sprinkler head and a planar ring extending radially outwardly from the dome for engagement with the trim ring of the fire sprinkler head. The rim is provided with means for securing the fire sprinkler head paint cover to the fire sprinkler head during painting operations thereby protecting the fire sprinkler head against damage due to paint over spray, etc. When the painting of the surface comprising the fire sprinkler head has been completed the securing means facilitates disengagement of the fire sprinkler head paint cover from the fire sprinkler head without danger of damage thereto.

Problems solved by technology

The painting of surfaces having fire sprinkler heads therein involve inherent danger that the fire sprinkler heads will be damaged thereby releasing pressurized water.

Particularly in the case of glass vial type fire sprinkler heads the removal of the masking materials following painting operations involves the inherent danger that the vial will be broken and pressurized water released.
