Definitions

  • the present invention relates to an emergency ladder intended to be hung on an upper floor of a house or building, along the facade and comprising fireproof cables on which are fixed at regular intervals, metal steps having a substantially face level when the ladder is suspended in the service position.
  • It relates in particular to an emergency ladder which, in the event of a fire, is intended to be hung on the upper floors of a house or building in the immediate vicinity of an escape route or a window, and which, in the event of fire, is simply unrolled, in order to allow the evacuation of the upper floors, even before the arrival of the emergency services.
  • a roll-up ladder made of non-flammable material is described in German patent application No. 2,733,944 (LUCKEY). It has two cables on which are fixed by their ends metal steps made of folded profiles in the shape of an inverted U. The steps are arranged at regular intervals and are only fixed by a single mechanically clamped nipple using a press against the cable
  • the rescue device according to the present invention is intended to remedy the above drawbacks and constitutes an emergency route from any emergency exit located on the upper floors.
  • the invention relates to a rescue appliance comprising a suspended emergency ladder intended to be hung on an upper floor of a house or building, along the facade and comprising fire-retardant cables to which metal steps are fixed at regular intervals. flat, essentially characterized in that said steps are fixed to each of the cables using clamping members preventing the movement of each of the steps along the cables.
  • At least one clamping member of each said pair is made of mnemomorphic alloy.
  • the ladder advantageously includes four cables.
  • the above cables are attached to a transverse telescopic bar, parallel to the steps, intended to bear against the frame of a window.
  • the rescue appliance is preferably rolled up and stored around a ballast.
  • the rescue apparatus consists of a ship pilot ladder 1 intended to be hung on the upper floors of houses and buildings in order to create an escape route in the event of a disaster, in particular of fire.
  • Ladder 1 has four steel cables and a series of metal steps 3, arranged at regular intervals. These cables are attached to a telescopic bar 4 or to at least one hook.
  • the ladder 1 can be attached to the frame 5 of a window or be unwound along a flat wall or a flat facade.
  • the main advantage of the rescue apparatus is that it allows the survivor to put his feet on a horizontal plane formed by the flat face of each of the steps 3, even if the ladder is hung along a wall or a facade. With a traditional rope ladder, this is not possible because the steps are made of narrow round pieces of wood, which only offer a reduced bearing surface when they rest against a flat wall.
  • FIG. 2 illustrates the constructive modifications that must necessarily be made to a rope ladder, in order to be able to use it, along a wall or a flat facade.
  • the embodiment recalls the characteristics of a ship pilot scale. However, it is distinguished by the means of attachment, as well as by the materials and mounting.
  • the rescue apparatus comprises two pairs of cables 2 to which rectangular steps are fixed at their ends, in the vicinity of each corner, by clamps or coupling sleeves (Figure 3).
  • first coupling sleeve 8 a reinforcing ring 9, a step 3 and a second coupling sleeve 8 'optionally provided with a reinforcing ring 9'.
  • the two clamping sleeves 8 are fixed securely, to make them non-slip when subjected to the weight of a survivor fleeing.
  • These tightening sleeves 8 are generally made of copper alloy.
  • the adapter sleeves can be applied mechanically to the cable by permanent deformation using a press.
  • the temperature range in which the change of structure can take place is quite narrow and is freely chosen by the choice of the composition of the alloy generally below 120 ° C.
  • mnemomorphic alloy which can be used is made on the basis of copper, aluminum and zinc. It has the following composition:
  • the cable and the sleeve are coated with Scotch Weld 2214 type glue.
  • FIG. 7 is a diagram showing, as a function of the length L of the sleeve and for a determined diameter, the force F to be used to overcome the adhesion of the sleeve and to slide the latter along the cable.
  • the alloy used is the PROTEUS 1163 ® alloy
  • Each anchoring sleeve consists of a metal cylinder (8) pierced with a longitudinal hole through which a cable is threaded. By heating to 120 ° C, the sleeve shrinks and encloses the cable (Figure 3), keeping a much smaller cylindrical shape.
  • Tests have been carried out by the AIB to determine the performance of a rescue ladder according to the invention, with a view to its approval.
  • rings or bands forming a clamp collar are used, including the ends form ledges arranged one opposite the other. This clamping ring or band is fixed to the bundle of steel filaments and tightened by means of a single nut.
  • split hubs 10 can be used, which are mounted around the cable on each side of each of the steps by means of a screw and a nut.
  • the screw can advantageously be mounted on the side wall of the step 3.
  • the steps are fixed by means of clamps 12, which are fixed along the side walls 13 of an aluminum profile.
  • the clamps 12 consist of a collar 14, the ends of which are provided with a thread 14 'and a clamping plate 15. ( Figure 6)
  • the clamps 12 are mounted in such a way that the cable strands disposed against the clamping plate 15 rest there without being deformed by the collars and that the external face of the plate 15 is fixed to the side wall of each step, in which two holes 16 have been fixed, in order to receive the rods of the collars 14 on which the nuts 17 are tightened, possibly after having been provided with a reinforcing washer, in order to fix the step to the cables 2.
  • the rescue device according to the invention has great advantages over an existing rope ladder. It is made of non-flammable materials. It can be stored in rolled up form in a room taking up little space.
  • hooks or a telescopic bar 4 constituted for example by a cylindrical body 19 in which slide one or two eclipsable rods 20.
