Definitions

  • the present invention relates to a fire curtain, that is to say to a curtain or screen which is installed in a theater or in a similar room, to allow, in the event of a fire, to effectively isolate the 'space located in front of the proscenium of the space behind the proscenium.
  • such a curtain which must be solidly constructed of metal and therefore has a significant weight, is always suspended from a lifting device, hoist or the like, which is provided with a mechanism for immobilization to maintain the curtain in its upper position, said curtain being generally provided at each end with a counterweight which, once said immobilization mechanism is released, must somewhat slow down the descent of said curtain, and means being further provided which, when said curtain has almost reached its lower position, must brake the subsequent descent of said curtain.
  • These latter means are generally constituted by cylinders filled with air, which are each provided with a small outlet orifice, the piston of these cylinders being set in motion by the descending curtain, more especially at the end of the movement of the descending curtain. , in order to expel through said small orifice the air present in the cylinders and to obtain a braking action on said curtain.
  • the present invention therefore relates to such a fire curtain, which is positively driven both in its downward movement and in its upward movement, said curtain being able to be maintained in any position and the construction, very simple but extremely effective, being able to be carried out in a simple and very reliable manner, on the one hand, while the safety of the suspension is as high as possible, on the other hand.
  • said fire curtain consists of the association of the curtain itself, of two cables to which said curtain is suspended and of a hydraulic cylinder, which is mounted between said cables and a fixed structure, to allow bringing said curtain, as the case may be, in the high position or in the low position.
  • FIGS 1 to 5 show a fire curtain 1, which is mainly constituted by profiled panels 2 of sheet steel fixed in a frame 3, so as to form a rigid assembly.
  • a fire curtain 1 which is mainly constituted by profiled panels 2 of sheet steel fixed in a frame 3, so as to form a rigid assembly.
  • the cable 4 passing, in this case, on a first idler pulley 6 mounted on an axis 7, which is itself supported in a structure 8 suitable, and then on a second idler pulley 9 mounted on an axis 10 which, by means of a suitable U-shaped support 11, is fixed to the free end of the piston rod 12 of a hydraulic cylinder 13 , the body of which is appropriately fixed, for example also to said structure 8, this fixing being, in the present case, carried out by fixing the body of said hydraulic jack 13 to the cross members 14 and 15 of said structure 8.
  • the cable 4 is then brought back under the idler pulley 9 and is finally fixed to said structure 8, more particularly to a cross member 16 provided for this purpose.
  • the cable 5 on its side, passes on a mad pulley 17 my tee on an axis 18 fixed in an appropriate manner in said structure 8, and is then led on an idler pulley 19 mounted on an axis 20 fixed to a support 21, 22, itself fixed to the structure 8.
  • the cable .5 After passing around the idler pulley 19, the cable .5 passes over a third idler pulley 23, which is mounted next to the idler pulley 9 on the axis 10 fixed in said support 11. Then the cable 5 is finally also fixed to said cross member 16.
  • FIG. 5 also shows schematically that the hydraulic cylinder 13 will preferably be provided with a limit switch damping system consisting, in the present case, in that a conical appendage 25, situated at the end of the piston 24 of the hydraulic cylinder 13, cooperates with a conical cavity 26 provided in the bottom of the body of the hydraulic cylinder 13.
  • a limit switch damping system consisting, in the present case, in that a conical appendage 25, situated at the end of the piston 24 of the hydraulic cylinder 13, cooperates with a conical cavity 26 provided in the bottom of the body of the hydraulic cylinder 13.
  • Figure 5 also schematically shows that for ser the curtain, oil is brought, via a piloted check valve 27, behind the piston 24, which has the effect, on the one hand, that the piston moves and, on the other hand, that the oil which is in front of the piston, is evacuated by the piloted check valve.
  • a hydraulic valve 13 is connected to a flap valve 28, which is connected by a line 29 to an oil reservoir, not shown, a normally closed valve 30 being provided in the line 29.
  • the purpose of this valve 28 is to ensure that that in the event of a rupture of the pipe 29, the valve 28 would close, due to an exaggerated flow speed of the oil, so that, on this side also, an untimely descent of the curtain cuts - fire is avoided in the event of a pipe rupture.
  • FIGS. 6 to 8 The execution according to FIGS. 6 to 8 is similar to that described with reference to FIGS. 1 to 5, with the simple difference that the hydraulic cylinder is significantly shorter, which can be advantageous in the event of lack of space.
  • the cables 4 and 5 are arranged like those of a multi-strand hoist on a larger number of pulleys.
  • the cable 4 is driven on a mad pulley 6 mounted on an axis 7, from where it passes over a mad pulley 9 mounted on an axis 10, from where it is brought back on a second mad pulley 31 mounted on axis 7, from where it passes over a second idler pulley 32 on axis 10, to be finally fixed to said crosspiece 16, while the cable 5 passes over the idler pulley 17 mounted on the axis 18, from where it passes over the idler pulley 19 mounted on the axis 20, from where it passes over a third idler pulley 34 mounted on the axis 7, from where it still passes over a fourth idler pulley 35 mounted on the axis 10, to be finally fixed to said crosspiece 16.
