Definitions

  • ABSTRACT A fire extinguishing system in which branch conduit means branching off from main conduit means near the ceiling ofa building, e.g., a warehouse, are in their ineffective position retracted and stored near the ceiling of the respective storage room or the like, and are released in case of fire in the vicinity thereof so as to freely hang downwardly to a plane near the floor of the building while control means normally preventing fluid connection between said main and branch-off conduit means establish such fluid connection.
  • the present invention relates to a fire extinguishing system for warehouses, supply and assembly halls, and similar buildings, in the form of a flexible hose of rubber or synthetic material which is suspended below the ceiling of the building and is connectable to a source of a fire extinguishing medium while being provided with lateral spray openings.
  • the fire extinguishing system according to the present invention is characterized primarily in that the downwardly hanging hoses, when in their inactive condition, are folded together to a fraction of their length or in rolled-up condition are detachably supported by the ceiling of the warehouse.
  • the hoses are expediently released from their inactive to their active position. simultaneously with the supply ofa fire extinguishing medium to the hoses.
  • the practical design for the holding means for the hoses may vary.
  • the holding means may consist of a bag or sack of a foil of synthetic material which sack or bag has one side seam adapted to be torn open.
  • the bag or sack which receives the folded together or rolled-up hose is connected to the ceiling structure or to the pipe line system for supplying the fire extinguishing medium, or to any other suitable stationary structural element.
  • a band of elastic material may be employed which is looped around the hose windings and which either has a preformed or prepared breaking area or which can be detached without being destroyed so that it can be used anew.
  • the invention is shown by way of example as a fire protective system for a warehouse.
  • Piles of goods 2 are located on the floor 1 of the warehouse.
  • Each pair of piles of goods 2 has associated therewith a fire extinguishing system.
  • a fire extinguishing system comprises in all instances a flexible hose 3 which by means of a screw connection 4 is connected to a rigidly and stationarily mounted conduit 6 for furnishing the fire extinguishing medium.
  • Hose 3 is connected to the underside of the ceiling 5 by means of clamps 6a.
  • the hoses 3 have their lower free ends closed by blind couplings 7.
  • the hoses 3 are over the major portion of their length provided with spray openings 8 through which the fire extinguishing medium or fluid can radially pass in all direction.
  • an electromagnetic shut-off valve 9 which normally blocks the passage of fire extinguishing medium therethrough, and only in response to the energization of its actuating magnet by a source 10 of current as a result ofa control pulse initiated by a smoke detector 1 1 will said valve 9 permit the passage of fire extinguishing medium into the hoses 3.
  • a travelling crane 12 which is movable on rails 13 over the entire length of the warehouse and which is provided with lifting means not shown for receiving the piled up goods.
  • the hoses 3 of the fire extinguishing system are, in conformity with the showing on the left-hand portion of the drawing, folded to a flat bundle and are within the region of the screw connection 4, by means of relatively thin foil strips 14 of a thermoplastic synthetic material, suspended on the conduit 6.
  • the tire extinguishing system according to the present invention does not impede the horizontal movement of cranes and the like and thus does notimpede the transport of the goods while at the same time it does not affect the efficiency of the fire protective system in case of an emergency.
  • the holding means for the suspended hoses are so designed that they will reliably support the weight of the hoses in the inactive condition of the tire protective system but will quickly release the hoses in case of an emergency.
  • No special mechanical actuating means are required to convert the system from its inactive to its active condition so that failures in the performance of the system are practically impossible.
  • a stationary fire extinguishing system which includes: main conduit means extending near and approximately parallel to said ceiling and adapted to be connected to a source of fire extinguishing medium, a plurality of branch conduit means comprising perforated flexible hoses branching off from and in communication with said main conduit means and movable from a retracted position near said main conduit means to an effective position in which said branch conduit means freely hang downwardly from said main conduit means to a plane near the floor of.
  • holding means arranged near the ceiling of said building and adapted to hold said branch conduit means in said retracted position, said holding means being adapted in case of a fire occurring in the vicinity thereof to release said branch conduit means so as to cause the latter to move automatically to said effective position, and control means normally preventing the flow of a tire extinguishing medium from said main conduit means into said branch conduit means, but operable automatically in response to the outbreak of a fire in the vicinity of said branch conduit means to establish flow of fire extinguishing medium to said branch conduit means.
  • said holding means are in the form of bags having at least one section formed by foil means of synthetic material detachably connected to each other.
