  • Patent number: 6691790
    Abstract: A fire suppression sprinkler system (10), and method for installing a sprinkler system (10)in new and existing buildings. The system includes a manifold (12) that supplies fire-suppression fluid to a set of wall-mounted sprinkler heads (14) via flexible sprinkler head conduits (16) through an unobstructed path (18). The installation and retrofit methods include determining the location of the sprinkler head (14), installing the manifold (12), making sure that there is an unobstructed path (18) between the manifold (12) and the sprinkler head location, running the conduit (16) through the path (18) by snaking it where necessary through the wall (50) to which the sprinkler head (14) is mounted, connecting the conduit (16) to the manifold (12) and sprinkler head (14), and then mounting the sprinkler head (14).

  • Publication number: 20040026533
    Abstract: The invention features an apparatus and method for positioning and supporting a sprinkler head in a ceiling, floor, or wall. In one aspect of the invention, a sprinkler head may be received by a sleeve extending through a broad surface of the plate. The plate may be configured to be removably attached to a support structure in the ceiling, floor, or wall and having an exterior surface exposed to the room or the plate may be attached to a decorative panel which is configured to be removably attached to a support structure in the ceiling, floor, or wall and having an exterior surface exposed to the room. The sleeve may be defined by an opening in the plate or it may be a separate structure permanently or removably attached to the plate.

  • Publication number: 20030066658
    Abstract: A central hub includes a plate and a sleeve attached to the plate and adapted to receive a sprinkler head. The sleeve may be a telescoping sleeve. By providing a central hub with the plate and sleeve, the central hub provides increased stability and versatility to the sprinkler head. The plate provides additional stability and support to the sleeve, and thus the sprinkler head, rendering the combination better able to operate effectively when high fluid pressures are utilized. The central hub is generally attached to a support structure by some mechanism, such as a leg. The addition of the plate adds versatility by increasing the number and variety of legs that can be used to attach the central hub to the support structure.

  • Patent number: 6123154
    Abstract: A system is provided for maintaining a sprinkler head in a position to allow continued operation during a fire in the event that the support structure for the sprinkler head fails or is otherwise removed. The support system includes a central hub adapted to receive a sprinkler head, a first leg attached to the central hub and having first and second ends. The support system also includes first and second ends having fastening devices adapted to attach the ends to the support structure. The fastening devices are configured to break away from the support structure in the event of support structure failure.

  • Patent number: 6119784
    Abstract: A support system for positioning a sprinkler head relative to a support structure in a ceiling, floor, or wall includes a central hub adapted to receive the sprinkler head, a first leg attached to the central hub and having a first end configured to be attached to the support structure, a second leg attached to the central hub and having a second end configured to be attached to the support structure, the second leg being spaced-apart from and substantially parallel to the first leg. The support system combines increased flexibility in installation with increased support for the sprinkler head during operation.
