Definitions

  • the application relates to a concealed sprinkler according to the features of the first claim.
  • the invention is suitable in the event that sprinklers are to be embedded with a cover in ceiling panels and the cover should be removable in a simple and effective manner, the sprinkler should be triggered in time when reaching a certain temperature.
  • the sprinkler is suitable for the use of an air- and heat-permeable, decorative cover that frictionally, z. B. by means
  • the cover can be removed by two independent events, namely purely temperature-dependent, with the cover removed as intended, before the sprinkler triggers or alternatively by the escaping extinguishing agent as a result of the sprinkler opening.
  • the sprinkler is also suitable for installation in walls or floors.
  • the sprinkler is also suitable for installation in ceiling panels and ceiling materials such as concrete.
  • the invention is suitable for making a concealed sprinkler from conventional sprinklers of different manufacturers.
  • Sprinklers in fire extinguishing systems are usually screwed to a pipe that protrudes through the ceiling of the corresponding room, so that the sprinkler can be triggered in the event of a fire on the object to be deleted and distributes the extinguishing liquid on the response of the trigger element on the fire.
  • the arrangement of sprinklers in workrooms such as laboratories, production facilities and warehouses is unproblematic, since these are functional areas in which such devices do not interfere.
  • sprinklers are also arranged in rooms with a selected aesthetic architecture in which they can have a disturbing effect. In this case, it is common to install the sprinkler completely or partially sunk into the ceiling, where it is still visible. In special cases, it is installed as a concealed sprinkler, that is, the sprinkler is embedded in the ceiling of the building and provided with a cover. For this purpose, a variety of solutions are known.
  • US 4,976,320 describes a concealed sprinkler whose cover is also removed by an ejector and via a spring.
  • the cover is a simple plate that is unlikely to cause much damage when dropped. Complicated, however, the mechanism is designed, which ensures that the cover is repelled by a spring.
  • the solution according to the invention provides a sprinkler, which is arranged in a mounting hood, which in a ceiling, for. B. concrete, a suspended ceiling or a ceiling panel is attached, wherein the cover is arranged by means of magnet on the sprinkler or on the mounting cap and is removed in case of fire by the pressure or the pulse of extinguishing water.
  • the magnets may be one or more magnets.
  • the magnetic force on the hood of the sprinkler is designed so that the cover is removed by the escaping extinguishing agent.
  • a resilient element is arranged between the cover and the spray plate of the sprinkler that is stretched in the standby state by means of fusible link and relaxed at a predetermined temperature by desoldering and the relaxed spring by overcoming the adhesive forces of the magnets removed the cover.
  • the desoldering temperature is preferably below the triggering temperature of the sprinkler.
  • other heat-sensitive systems such as a bimetal, can also be used for a temperature-dissolving adhesive bond o. A. be used.
  • the fusible linkage together with spring is preferably present only at one point of the cover.
  • the preferably centrally disposed spring may be connected to the cover only by means of fusible link or other heat-sensitive means. But it is also conceivable another attachment, for.
  • the sprinkler is preferably located in the middle of the fastening hood, which preferably has a rotationally symmetrical shape.
  • This shape may be bell-shaped, conical or cylindrical.
  • the cover can be a flat round metal plate that matches the shape and color of the ceiling trim. Other, not circular Designs are possible. If necessary, the cover may have holes or apertures of any shape.
  • the magnet can be arranged on the cover at the edge of the fastening hood or on the sprinkler plate. It is advantageous if the attachment hood or the cover of the attachment hood are made of metal.
  • the hidden sprinkler has the advantage that in the event that the fire heat passes from the top of the sprinkler, the sprinkler initially triggers and removed with magnets attached cover through the fire water and, if the fire heat from below reaches the sprinkler, the cover is removed by means of spring by the melting of the fused solder and the sprinkler can trigger faster than is the case with other sprinklers of this type.
  • Figure 4 sprinkler with cover in a concrete ceiling.
  • FIG. 1 shows a concealed sprinkler 2, consisting of the fastening hood 1, which consists of metal and in the center of which the sprinkler 2 with spray plate 9 is arranged.
  • the magnets 3 are arranged, which hold the round cover 4, which consists of metal.
  • the cover 4 is fastened by means of fastening screws 8 with the attachment 11 to the housing.
  • the cover 4 has openings corresponding to the design of the ceiling coverings 5, by which in the event of a fire extraordinary warming can be registered, which then cause the bursting element 6 shatters in the sprinkler 2 and the path of the fire-extinguishing water in the mounting hood 1 above the cover 4 releases. Due to the escaping water falls Within a very short time the cover 4 from, so that the deletion can take place. This is especially important when fire heat from above. the sprinkler 2 passes.
  • the device has the advantage that the cover on the sprinkler with little effort and high reliability is fastened.
  • FIG. 2 shows the sprinkler 2 with bursting body 6 and mounting hood 1, which is screwed by means of connecting thread 7 to a line and under the spray plate 9, the cover 4 is fixed with magnets 3 on the mounting hood 1, wherein a soldered spring element 10 in the center of the cover 4 is arranged.
  • a soldered spring element 10 in the center of the cover 4 is arranged.
  • the solder substance melts on the spring element 10 and the spring element relaxes properly on the spray plate 9, so that the cover 4 is blown off by the spring force.
  • the fire heat then reaches very quickly the bursting body 6, which triggers the sprinkler immediately, creating a quick fire fighting is initiated.
  • FIG. 3 shows a sprinkler 2, the cover 4 of which has become detached after melting of the molten solder by relaxing the spring 10, wherein the magnets 3 are fastened to the cover 4 and the bursting element 6 of the sprinkler 2 has not yet triggered, since its response temperature not quite reached yet.
  • FIG. 4 shows a sprinkler 2 with cover in a concrete ceiling 13 onto which a plaster layer 12 has been applied.
  • the connecting thread 7 or the long-threaded sleeve 14 is screwed.
  • the attachment option 11 is clamped between sprinkler 2 and the connecting thread 7.
  • the mounting option 11 is fixed by three fasteners, in the present case fastening screws 8, the mounting hood 1, in which the sprinkler is located.
  • the cover 4 with the thermal spring release element 10 has three magnets 3 and is held with these on the mounting hood 1. List of reference numbers used
