  • Patent number: 10493307
    Abstract: A flexible dry sprinkler includes an inlet, an inlet seal assembly having a spring seal that compresses in response to a longitudinal load, and an inlet release unit. A flexible tube has an inlet end and an outlet end, and a flexible linkage extends through the flexible tube, and is connected to the inlet release unit. An outlet release unit is connected to the outlet end of the flexible tube and to an outlet end of the flexible linkage, and displaces the outlet end of the flexible linkage upon activation of the flexible dry fire protection sprinkler. A sprinkler body is connected to the outlet release unit, and has an outlet orifice sealed by an outlet seal assembly until ambient temperature reaches a predetermined temperature. When the ambient temperature reaches the predetermined temperature, translation of the flexible linkage in an outlet direction causes release of the inlet seal assembly.

  • Publication number: 20180353786
    Abstract: A dry sprinkler has a casing tube having an inlet orifice and an outlet orifice. When the sprinkler is in a non-actuated state, an inlet seal assembly operatively seals the inlet orifice and an outlet seat assembly operatively seals the outlet orifice. A translating member extends through the casing tube between an inlet and an outlet. The translating member axially translates from a first position, in which the translating member retains the inlet seal assembly in a sealed state, to a second position, in which the translating member releases the inlet seal assembly, toward the outlet when the outlet seat assembly is released. The sprinkler has a nominal K-factor greater than 17 gpm/(psi)1/2. In addition, a difference between a cross-sectional area of the casing tube and a cross-sectional area bounded by an outer perimeter of the translating member is more than 30% of the cross-sectional area of the casing tube.

  • Patent number: 10046190
    Abstract: A horizontal sidewall fire protection sprinkler includes a sprinkler body, a sealing assembly, a sleeve body, a yoke, a load screw, levers, a soldered link, a slide plate, a deflector support member, a deflector, and a spring. When ambient temperature in an occupancy reaches a predetermined temperature, the soldered link fails, the levers release, and the yoke and the load screw are forced away from the sprinkler body. The spring forces the slide plate and the deflector support member away from an inner wall of the sprinkler body toward an opening at an outer end of the sleeve body, and the deflector support member and the deflector protrude from the outer end of the sleeve body. The sealing assembly is released from a sealed state, and the fire protection sprinkler outputs fluid from a fluid supply to the occupancy.

  • Publication number: 20170216642
    Abstract: A horizontal sidewall sprinkler is provided which includes a sprinkler body having an inlet passage for supply of a fluid and an outlet, the outlet being closed by a sealing assembly prior to actuation of the sprinkler. The sprinkler further includes a sleeve body secured to the sprinkler body and a yoke substantially spanning a width of the sleeve body, the yoke urging a load screw against a surface of the sealing assembly facing an occupancy, and being held in place prior to actuation of the sprinkler by two levers that are joined by a soldered link. A slide plate is located near an inner wall of the sprinkler body facing the occupancy prior to actuation of the sprinkler. According to one example embodiment, a frame or two guide pins are provided for bearing and supporting a deflector. The deflector is positioned between the load screw and the sealing assembly thereby obstructing a flow of fluid from the outlet upon actuation of the sprinkler.

  • Patent number: 8800673
    Abstract: An attic fire protection system is provided. The system comprises a fluid supply manifold for supplying a fluid, positioned at an effective height below and parallel to the underside of a roof having a non-zero pitch angle. The system contains a plurality of fittings each having at least one exit port for directing the flow of the fluid, the fittings being spaced within at most a maximum effective distance apart from each other and being connected to receive fluid from the supply manifold, wherein the exit ports are structured to supply the fluid in a direction parallel to the underside of the roof. Most broadly, however, the fittings are structured or arranged to supply the fluid in a direction forming an oblique angle with the horizontal and the vertical, which may or may be exactly the same as the pitch angle of the roof. The system also includes a plurality of horizontal sidewall sprinklers each connected to a respective exit port of one or another of the fittings.
