CONCEALED RESIDENTIAL SPRINKLER

摘要

A combined trigger and concealing device for an automatic fire protection sprinkler includes a first plate attached to a second plate by a heat fusible material. Each plate is formed with an aperture which receives an actuator depending from the bottom of the sprinkler. The trigger device depends a preselected distance from the bottom of the sprinkler body and includes a cover which has an outer dimension which conceals the internal components of the sprinkler from view. The cover includes openings and is dimensioned and positioned to permit heat energy to be received by the inner and outer surface of the trigger device. Conduction of heat energy from both the inner and outer surface of the trigger device permits the heat fusible material to be expeditiously raised to the preselected separation temperature. This construction minimizes response time of the sprinkler while maintaining a highly aesthetic appearance.

主权项

1. A trigger device for an automatic sprinkler having a deflector positioned within the interior of a sprinkler body, wherein the sprinkler is actuated when a first and a second actuator depending below the bottom of the body are moved from a closed position to an open position, said trigger device comprising:
a first plate having a first actuator aperture therethrough dimensioned to receive the first actuator; a second plate having a second actuator aperture therethrough dimensioned to receive the second actuator, heat fusible material attaching said first and second plates together when in an assembled condition; and a cover attached to said second plate and having an outer dimension, wherein said first and second plates have an assembled outer dimension, and said cover outer dimension is approximately at least as great as the assembled outer dimension so as to substantially conceal the assembled first and second plates.
