SPRINKLER EXTINGUISHER
Document Type and Number:
Japanese Patent JP3647195
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent an adjacent sprinkler head from being exposed to aimed water by disposing a water exposure preventing means opening at the time of water aiming of this sprinkler head but closing at the time of water aiming of the adjacent sprinkler in the neighborhood of the sprinkler head with a heat sensing part.
SOLUTION: Water exposure preventing walls 5a and 5b are arranged between sprinkler heads 1a and 1b with heat sensing plates 4 to form a water exposure preventing means. Thereby, extinguishing water from the heads 1a and 1b is prevented from watering to mutually adjacent plates 4. The lower tip parts of the respective walls 5a and 5b are set to positions lower than the plates 4. In addition, the walls 5a and 5b are arranged opposite to each other and fixed with respective hinges 6a and 6b to open at the time of its own water aiming and to close at the time of adjacent water aiming. Thereby, its own water aiming is possible and exposure to water aiming from adjacent sprinkler head is prevented.
