    Abstract: A sprinkler guard, mountable to a fire protection sprinkler, includes a first plate with projections from the first plate in a first lateral direction orthogonal to a central axis, and a lower surface facing a downward direction opposite to the upward direction, a second plate with projections from the second plate in a second lateral direction opposite to the first, and a lower surface facing the downward direction, first and second legs having an upper end attached to the lower surface of the first plate, a middle portion extending in the downward direction, and a lower end, third and fourth legs having an upper end attached to the lower surface of the second plate, a middle portion extending in the downward direction, and a lower end. A circular ring is attached to the lower ends of the first to fourth legs, and the legs are spaced about the circular ring.

    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. 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.

    Abstract: A sprinkler with a push-in connection includes a sprinkler frame, an operating element, and a sealing cap. The sprinkler also includes one or more sealing gaskets and a retainer. Each such sealing gasket is located at least partially within a groove in the sprinkler frame. The retainer is also at least partially located within a groove in the sprinkler frame. The retainer connects to an internal bore of an outlet of a fluid supply conduit when the sprinkler is installed in the outlet. The one or more gaskets seal against the internal bore of the outlet when the sprinkler is installed in the outlet. The retainer is a spring mechanism so that the diameter of the retainer is reduced when the sprinkler is inserted into the internal bore of the outlet, and the retainer maintains pressure against the outlet internal bore.

    Abstract: A dry sprinkler includes a flexible tube section that maintains a pressurized fluid, such as a liquid antifreeze solution, between a first end and a second end. A first seal prevents fluid from a supply line from entering the flexible tube section. The first seal is maintained in a sealed position by a pressure of the pressurized fluid. A sprinkler head is coupled to the second end of the flexible tube section, and includes a frame, an output orifice, a deflector, a second seal that seals the output orifice, and a thermally responsive element configured to maintain the second seal in a sealed position when the thermally responsive element is in a non-responsive state. A differential pressure controller maintains a ratio between the pressure of the pressurized fluid in the flexible tube section and a pressure of a supply fluid in the supply line to at least a certain ratio.

    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.
