Definitions

  • the object of the invention is the smoke evacuation system intended for the ventilation and evacuation of the fumes which are formed during of the fire.
  • Smoke evacuation systems are intended for ventilation of premises and especially their smoke extraction in the event of fire. They are located in the roofs of industrial and public buildings. They are activated automatically as a result of the increase of the temperature which triggers the action of the opening system. The opening system can also act under the influence of smoke. This system actuates a driving element, in general a pneumatic or hydraulic cylinder. The cylinder rod is connected usually at the movable outlet panel. There are different smoke evacuation systems.
  • German patent No. DE 31 43 318 (FORTMEIER) which presents a device for the evacuation of smoke and heat, having a panel turned to the position opening by a jack whose rod is connected to the panel.
  • the cylinder is fixed in balance to the intermediary, mounted even balanced on the chassis of the device, on the hinge side of the panel.
  • the intermediary can take the position above the upper edge of the chassis, while in position of closing it is located, as well as the lower part of the jack above the bottom edge of the chassis.
  • the intermediary is locked in the extreme base position by an oleopneumatic spring whose stem is connected to the common axis of the cylinder base and the lower end of the intermediate.
  • GAASL European patent no. 0 443 050

  • the support lever constitutes an element of the articulated system which includes a second repellant lever, connected in rocker with the first lever and acting on the cross member of the outlet panel. during the opening and closing of the outlet panel, the lever and cylinder system moves out of the height of the outlet.
  • the cylinder is mounted in a balance on an outgoing support below from the base of the outlet.
  • the invention relates to a skylight having a curb having side walls which delimit the periphery of the lower and upper open faces, an opening frame having an articulated side on the edge upper side wall of the curb, the other sides being, in the closed position, situated on the periphery of the face open upper, the frame comprising a spacer arranged between its first side and the periphery of the frame, the skylight comprising a cylinder to actuate opening-closing means of the frame.
  • the opening means are rigidly fixed on the frame and have a pivoting element around a axis parallel to the articulation axis of the frame, the axis being mounted sliding along the cylinder axis, which is mounted hinged on the curb.
  • the mounted element pivoting around the axis is fixed on the spacer perpendicular to it.
  • the length of the element is less than the dimension of the curb between its open faces.
  • the element consists of two parallel and spaced bars.
  • the smoke evacuation system also consists of a panel fixed by one of the sides in tilting relative to the stationary chassis, a cradle connected to the chassis, a motor element mounted in articulation on the cradle , a set of two levers connected together in balance and at least one spring.
  • the outlet according to the invention has the modular structure.
  • the actuation assembly constitutes an interchangeable module mounted in the frame of the outlet.
  • the balance constituting one of the levers has three segments of which at least two segments are curved in a determined direction at an obtuse angle.
  • the pendulum is mounted in balance on the axis fixed to the cradle.
  • the intermediary constituting the second lever has three segments, two segments of which are curved in a predetermined direction at an obtuse angle and the third segment of the intermediary is curved in the opposite direction at an obtuse angle.
  • the intermediary is mounted in balance by the end of the segment bent in the opposite direction, on the axis fixed to the crosspiece of the panel.
  • the drive element is articulated on the cradle and the end of the drive element rod is hinged to the central segment of the balance.
  • the cradle and the balance constituting one of the levers, the intermediate constituting the second lever, the motor element and the spring make an interchangeable module mounted on the chassis.
  • the common axis of rotation of the balance and the intermediate is located at the end of the outer segment of the balance, opposite the axis of rotation of the balance, fixed to the cradle and at the end of the outer segment of the intermediate, opposite the axis of rotation of the intermediate, fixed to the crosspiece.
  • the end of the rod of the motor element can be fixed articulated between the ends of the central segment of the pendulum.
  • the spring is fixed at one end to the cradle and at the other end to the free end of the outer segment of the pendulum.
  • the balance constituting one of the levers, the intermediate constituting the second lever, the motor element and the spring are integrated, both in the closed and open position of the outlet, between the panel and the lower edge of the frame.
  • the driving element can be a pneumatic or hydraulic or electric actuator or oleopneumatic springs.
  • the outlet has at least one latch between the panel and the cradle, fixed on the opposite side with respect to the axis of rotation of the panel, released automatically by the mechanical, pneumatic, hydraulic or electrical action, simultaneously with the action of the motor element.
  • the exterior segment of the pendulum is bent in the opposite direction, at the right angle relative to the central segment of the pendulum, and the axis of rotation of the pendulum is located at the common end of these two segments.
  • the outer segment of the pendulum is bent in the same direction, under the obtuse angle relative to the central segment of the pendulum, and the axis of rotation balance is located between the ends of the outer segment, closer to the free end of this outer segment.
  • two segments of the intermediary adapt to the corresponding pendulum segments.
  • the advantage of the solution according to the invention is the construction compact outlet.
  • the modular design consisting of cradle in which the motor element is mounted with the pendulum, intermediate and spring, allows easy mounting and fast from the outlet. Integration of levers, element motor and spring between panel and bottom edge of the chassis allows, in the closed position, the storage and rational transport of outlets prepared for assembly.
  • FIG. 1 presents the outlet in its basic version, with the outer pendulum segment bent in the opposite direction, in the closed position - side view
  • fig. 2 presents the outlet in another version, with the external segment of the pendulum bent in the same direction, in position closed - side view
  • fig. 3 presents the outlet of fig. 2, in the open position - side view.
  • the smoke evacuation system has movable panel 1 which closes the ventilation hole.
  • Panel 1 is mounted on one side tilting with respect to chassis 2 and is fitted with the crossmember 3.
