• a moving means indicated as a whole with 6, suited to realize the rotation of said cover 4 around said hinges 5 to obtain the opening and closing of said apparatus and so of the opening 3 ;
• - hooking means indicated as a whole with 7, some belonging to the frame 140 of the cover and some to the counter-frame 120 suited to block said cover 4 while closing, against said counter-frame 120.
• said apparatus 1 is provided with a mechanical lock, indicated as a whole with 8, included in the moving means 6, which is used to block the cover 4 when it reaches the maximum opening position, indicated in figs 5 and 7, avoiding that can be accidentally closed, as for example because of the wind.
• the moving means, indicated as a whole with 6 comprise an articulate joint
• said articulate joint 160 composed by a plurality of pair of rods placed side by side, two by two and a pneumatic actuator, indicated as a whole with 260, where said articulate joint and said pneumatic actuator are connected one another and are located between said counter-frame 120, said basement 2 an said cover 4.
• said articulate joint 160 comprises:
• a first pair of rods 360 each one having a fulcrum connection on one extremity 361 with said basement 2 and another corresponding fulcrum connection on the other extremity 362 with the body 261 of said actuator 260; the end 262 of the stem 263 of said actuator 260 having, instead, a fulcrum connection with a crosspiece 42 belonging to the frame 140 of said cover 4;
• a second pair of rods 460 each one having a fulcrum connection on one extremity 461 with said crosspiece 42 of said cover 4 and another fulcrum connection on the opposite extremity 462 with the corresponding extremity 561 of a corresponding rod belonging to a third pair of rods 560, each one having a fulcrum connection on the opposite extremity 562 with said basement 2 in correspondence of the same position where the extremity 361 of corresponding rod of said first pair of rods 360 has a fulcrum connection;
• hooking means 7 which, as it can be observed in fig. 2, when the cover is closed, it is locked on the basement 2 through the already mentioned hooking means 7 which, as it can be observed in figs 12, 13 and 14, comprise a pair of beaks 71 connected to the extremities of a rod 72 positioned in transversal way on the cover 4, each of them hooks a reference striker 78 which belongs to the counter-frame 140.
• the rod 72 is supported by a pair of supports having extremity 73 and is provided of a protruding element 74 displaced in a substantially central position.
• Said protruding element 74 through a tie rod 75, is connected with a lever 76 having a fulcrum connection with a support 77 secured to the crosspiece 42 of the cover and also is connected with the extremity 262 ofthe stem 263 of the actuator 260.
• Concerning the pneumatic cylinder 260 by observing fig. 1 and 8 it can be noticed that the feeding way 461 of its positive chamber is connected through a first piping 269 to a first manifold 264 while the feeding way 561 of its negative chamber is connected through a second piping 369 to a second manifold 364.
• Said manifolds 264 and 364 through fast connections, respectively 268 and 368 are connected to a distribution center, not represented in the drawings, that through first distribution means, which are not represented in the drawings is fed with CQ under pressure.
• first distribution means which are not represented in the drawings is fed with CQ under pressure.
• special sensors displaced in the rooms intervene on said distribution means to permit the C0 2 flow in the first distributor 269 that through said first piping 264 and through the way 461, feed the positive chamber of the pneumatic cylinder 260 causing the exit of the stem 263 and so the opening of the cover 4.
• the stem begin moving its end 262 through the lever 76, the tie rod 75 and the rod 72, release the beaks 71 from the reference striker 78 and begins the lifting of the cover 4 supported by the thrust of the articulate joint 160.
• said stopping element is the fork 85 to which it is secured the extremity 91 of a shock absorber 9 which opposite extremity 92 has a fulcrum connection with said first rods 360 through a pin 93.
• the mechanical lock 8 avoids the cover rotation 4 around the hinges 5 and so it avoids its accidental closing as foreseen by the safety rules.
• the extremity 84 of the rod 81 presents an appendix 86, having a L shape and visible with more details in figs 8, 9 and 10, against which at least one locking device 150 co-operates and which comprises an actuator 100, secured to the basement 2, provided of a stem 101 which co-operates with said appendix 86. More precisely said actuator 100, as it can be observed, is fed by a piping 102 derived by a manifold 364 which feeds the actuator
• the operator carries out, through a manual remote control and using pressurized air, the same opening control of the cover which in the case of fire is performed automatically feeding the pneumatic cylinder 260 with C0 2 .
• the operator turn on the switch which is the control device and in this way the first manifold 264 is in discharge position and in the same time the second manifold 364 is fed with pressurized air.
• the compressed air which flows in the second manifold 364, feeds first the actuator 100 because it is disposed in a position very near to the manifold 364.
• the compressed air before feeding the negative chamber of the pneumatic cylinder 260, instantaneously fills the cylinder 100 and this causes the coming out of the stem 101.
• the last one contrasts against the appendix 86 of the lever 81 and, as it can be observed in fig 10, turn it round a pin 82 so to release it from the contrasting mean 85 before the pneumatic cylinder 260 begins the closing action of the cover 4. Therefore, the compressed air feeds the pneumatic cylinder 260 and begins the driving action on the stem 263 causing the clockwise rotation 162 of the cover 4, supported by the action of the articulate joint 160, till to a total closing of the cover which returns in the position, visible in fig.
• a transparent cupola 45 which allows the entrance of the light in the room is applied to the frame 140 of the cover 4.
• the articulate joint 160 differently from the articulate joints present in the known apparatus which substantially consist of an articulate triangle, consists of a plurality of rods connected among them which are co-opering among the cover, the frame and the basement to which they are connected. This enables to realize on the cover more powerful actions than those of known apparatus having equal dimensions. It is evident that during the manufacturing the apparatus according to the invention can be realized with whichever shape and dimension and can be even equipped with transparent cupola having whichever form.
• a further embodiment could consist of the cover being provided with a flat and not transparent closing surface.
• the apparatus for smoke evacuation can present more than one actuator which perform the opening and closing of the cover or it can be provided with moving means of the cover which even realizing the same constructive geometry consist of a different number of rods.
• different hinges and hooking means which block the cover in a closing position can be variously performed.
