Definitions

  • the present invention relates to smoke vent skylights.
  • the outlet to be tested is placed above a stabilization chamber in which a uniform static pressure is maintained and the flow rate of the outlet when it is open is measured.
  • the outlet is subjected to a side wind generated by a wind tunnel by rotating it relative to the wind in order to simulate all positions relative to the wind it could present during a fire.
  • the device is assigned a SUE (Useful Area for the opening of the outlet) in the form of a coefficient to be applied to its geometric surface.
  • the invention provides for this by a smoke vent skylight, robust and simple to manufacture, the opening of the shutter is reliable and safe and requires fluid pressures as small as possible to operate it, which remains in the closed position without be lifted by the wind or fall noisily and which returns in a soft and damped way, which leaves clear the space which surrounds it and which allows the use of fairly high curbs.
  • the subject of the invention is a smoke outlet comprising a parallelepipedic curb, the closing flap of which can pivot around a first upper side of the curb under the action of a jack mechanism characterized in that the mechanism comprises a first and a second jack, the free end of the rod of the first jack is articulated on the shutter and the head of the body of the first jack is articulated on an element pivotally mounted on the shutter, the free end of the rod of the second cylinder is articulated on the element between the point of articulation of this element on the flap and the point of articulation of the body of the first cylinder on the element and the head of the body of the second cylinder is articulated on the curb at a distance from the side opposite to the first side substantially at least equal to or just greater than the length of the body of the first cylinder.
  • the first jack makes an angle of 60 to 120 ° with the shutter in any position of the shutter 3 and the second jack makes an angle of 60 to 120 ° with the movable element both that this one makes with the curb an angle lower than 90 °.
  • the cylinders are substantially perpendicular to the load they have to move. They are effective and, when the flap returns, the stroke of the rod of the first cylinder in its body remains substantially proportional to the pivot angle of the flap, so that the damping due to the compression of the fluid remaining in the body can be done at best.
  • the point of articulation of the second cylinder at a distance from the first side substantially equal to the length of the body of the first cylinder is the best compromise between the need to move this point as far as possible from the first side to give a large lever arm to the second cylinder and therefore for it to be very effective and that of leaving the first cylinder the clearance allowing it to be housed, in the closed position of the flap, like the second cylinder, approximately vertically under the curb.
  • a locking device for unlocking by pressure of a fluid, retaining the flap on the side of the curb opposite the first side and comprising means for preventing fluid to actuate the cylinders until the locking device is unlocked. This prevents any danger of deformation of the curb under the untimely and powerful action of the jacks.
  • the outlet skylight comprises a parallelepipedic curb 1 having the shape of a box open upwards and downwards.
  • a translucent flap 3 in the form of a dome.
  • the free end of the flap 3 is locked on the other small upper side 4 of the curb 1 by a lock.
  • This lock comprises a latch 5 penetrating into a keeper of a conventional mechanical locking device 6.
  • the latch 5 is integral with a finger 7 itself fixed on the rod 8 of a piston 9 returned by a spring 10 housed in a cylinder 11.
  • the cylinder is pierced with two fittings 12 and 13 for connection to a source d compressed air and a pneumatic control circuit.
  • the fittings 12 and 13 come into communication via the cylinder 11 only when the piston is pushed against the spring 10 by the fact that the locking device 6 is opened manually or pneumatically.
  • a fixed cross member 14 connects the two lower short sides of the curb 1.
  • a fixed cross member 15 connects the two short sides of the shutter 3.
  • An element 16 is articulated at the bottom of the cross member 15 near the side 2.
  • the free end 17 of the rod 18 of a first cylinder is articulated in the middle of the cross member 15.
  • the head of the body 19 of the first cylinder is articulated at the free end 20 of the element 16.
  • the free end 21 of the rod 22 d '' a second cylinder is articulated at a point 23 of the element 16 intermediate between the end 20 and the bottom of the cross member 15.
  • the head of the body 24 of the second cylinder is articulated on the cross member 14 at a distance from the side 4 slightly greater than the length of the body 19 of the first cylinder.
  • Conduits 25 supply the cylinders with compressed air from the connector 13.
  • the outlet skylight works as follows:
  • the compressed air is sent to the connector 12 of the lock which releases the shutter 3 which it kept closed.
  • the pressure is then transmitted to the first cylinder.
  • the rod 18 of this jack then drives the crosspiece 15 and opens it at an angle of about 45 ° (the value of this angle is only specified for the purpose of understanding because it depends on the length of the jack used). Pressure is then applied to the second cylinder.
  • the second cylinder then drives the assembly of the first cylinder, of the cross member 14 and of the cross member 15 so that the flap 3 makes an angle of at least 140 ° relative to the fixing plane of the curb 1.
  • the air pressure is sent by another circuit first to the first cylinder, then to the second cylinder which, to complete the closure, engages the locking device 6.
