Definitions

  • the present invention relates to a smoke outlet or a similar roof opening, with a large clearance of the closure panel.
  • Such systems usually include a curb or such a support member, generally made of galvanized sheet steel, associated with a dormant frame, also metallic, on which is applied in the closed position an opening constituted by a solid panel or with transparent parts, this panel being hinged to the frame while the seal between the frame and the opening is made by a peripheral seal, lip or other, with flaps on the side of the panel hinges .
  • This may include a dome or glazing, added and possibly removable.
  • DE-A 3 143 318 describes a smoke outlet or similar roof opening, with a large clearance of the closure panel, comprising a support box for a sleeping frame on which is articulated around hinges provided on one of its edges, a opening panel, suitable for sealingly applied to the frame in the closed position, the tilting of the panel around the hinges being effected by means of a two-part cylinder, one part of which is articulated on the panel and the other is articulated at its opposite end on the box and capable of occupying one or the other of the two distinct positions, respectively for an opening of the panel corresponding to an angle slightly greater than 90 ° on the one hand, then for an opening with a significantly greater angle on the other hand.
  • the opening angle of the panel does not ordinarily exceed 110 ° relative to the horizontal plane where the frame frame is placed, a larger opening being generally prohibited as a result of the door false created then by the panel vis-à-vis its hinges of articulation and the efforts which are exerted on him because his center of gravity is all the more separated from the plumb of these hinges as the opening is larger.
  • the present invention relates to a smoke outlet or similar roof opening, which overcomes these drawbacks, by making it possible to reach a clearance angle much greater than that provided in conventional solutions, which can in particular reach 140 ° relative to the horizontal, experience having shown that, with such an angle, it is possible to avoid the presence of canopies, which therefore improves the appearance of the device and facilitates assembly at a lower cost.
  • the invention relates to a smoke outlet or similar roof opening, with a large clearance of the closure panel, comprising a support box for a sleeping frame on which is articulated around hinges provided on one of its edges, a opening panel, suitable for sealingly applying to the frame in the closed position, the panel tilting around the hinges being effected by means of a two-part cylinder, one of which is articulated on the panel and the another part is articulated at its opposite end on the box and able to occupy one or the other of the two distinct positions, respectively for an opening of the panel corresponding to an angle slightly greater than 90 ° on the one hand, then for a opening with a noticeably larger angle on the other hand, characterized in that the panel is joined by a tension spring to a rocking lever articulated on the box and brought into position of support against a stop thereof for the first open position, the spring being tensioned between the panel and the lever thus immobilized until this panel reaches the second open position.
  • the tension spring is traversed by a guide rod, fixed to the panel and passing through a bore provided in an axis carried by the rocking lever, this rod comprising at the end, at its end opposite to the panel, a shoulder d 'stop for a compression spring, capable of damping the movement of the panel at the end of its travel when it reaches the second open position.
  • the panel opening angles corresponding to the first and second positions are close to 110 ° and 140 ° respectively.
  • the reference 1 designates, as a whole, the smoke outlet considered, comprising mainly a box 2, with square, rectangular or circular section or other, the particular shape adopted having no effect on the implementation of the means of the invention.
  • This box 2 or “curb” is applied against the generally horizontal surface but which could be inclined with a roof 3 and has at its opposite end, near its open edge, an outer frame 4 forming a frame and on which is intended to be applied in the closed position of the outlet, a tilting panel 5.
  • the latter comprises a peripheral frame 6, suitable for being applied to the standing frame 4 with interposition between them of a seal (not represented).
  • the tilting panel 5 also comprises a cover 7, integral with the frame 6, which can be solid or transparent.
  • the tilting panel 5 is articulated on the box 2 around hinges 8, in order to allow an appropriate tilting with respect to the frame 4, produced by means of a gas spring 9, the invention aiming to allow the opening of the panel, first to a first position where it forms substantially with the horizontal, that is to say with the plane of the sleeping frame 4, an angle of approximately 110 ° (FIG. 2), then, beyond, the tilting continuing, to bring the panel into a second open position corresponding to an angle of about 140 ° ( Figure 3).
  • the jack 9 controlling the opening of the panel 5 relative to the box 2 comprises a body 10 and a rod 11 capable of disappearing inside the body depending on whether the panel is in the closed position or d 'opening.
  • the body 10 is articulated around an axis 12 on the frame 6 of the panel 5, this axis 12 being supported by a yoke 12a provided on this frame.
  • the rod 11 is itself articulated around an axis 13 at the corresponding end of a rod 14, itself articulated opposite the axis 13 around a axis 15 carried by a box 2.
  • the link 14 can thus occupy two positions, illustrated respectively in Figures 2 and 3 for which, in one, it is placed substantially in the extension of the rod 11 and the body 10 of the jack 9 (opening at 110 °) and in the other, it has pivoted about 90 ° to come approximately in the plane of the upper edge of the box 2 (opening at 140 ° to the panel).
  • the equipment of the device is completed according to the invention by means of a tilting lever 16, itself articulated around an axis 17 on the box 2, this axis 17 arranged along the length of the lever so that it it delimits beyond a clean heel 18 coming, at the end of its tilting movement, pressing against a support stop 19, provided on the box and immobilizing the lever in this raised position relative to the plane of the frame 4.
  • the lever 16 At its end opposite the heel 18, the lever 16 has a transverse axis 20 which can freely rotate on itself (FIG. 4). On the extension of this axis is fixed a tension spring 21, the opposite end of which is linked to the frame 6 of the panel, rocking around a point of attachment 22. A rod 23 is housed inside spring 21 and arranged to pass freely through a bore 24 provided in an extension 25 of the axis 20. The latter is stopped on the lever 16 by a flange 26.
  • the rod 23 finally comprises, beyond the lever 16 relative to the tension spring 21, a stop shoulder 27 for another spring 28, intended to come to work in compression in abutment against the door formed by the extension 25 of the axis 20 when the tilting panel 5 is in the position of maximum opening (opening 140 °), as shown in Figure 3.
  • the panel 5 being in the closed position, as illustrated in FIG. 1, with its frame 6 applied to the frame 4 of the box 2, control by the jack 9 the progressive opening of this panel thanks to the relative movement of the rod 11 of the jack with respect to the body 10 and to their respective articulations on the panel 5 and on the box 2 around the axes 12 and 13.
  • This opening movement continues gradually and regularly until the panel 5 comes into a first position illustrated in FIG. 2, where the jack 9 is substantially in the extension of the articulated link 14.
  • the lever 16 has simultaneously pivoted with the panel 5 until bringing its heel 18 against the stopper 19. In this position, the panel 5 makes an angle with the frame 4 which, in the example considered, is close to 110 °.
  • the panel sees its center of gravity move more and more in overhang relative to the hinges 8, driven by its weight it pivots abruptly around its articulation to come at the end of the race in a second position illustrated in Figure 3 with an opening which is here chosen of the order of about 140 °.
  • the tension spring 21 is suddenly tensioned and serves to stop the panel, if necessary, in cooperation with a limit stop limit stop (not shown).
  • the compression of the spring 28 occurs on the bearing surface 25 of the axis 20 by damping the final stroke of the panel.
  • the tension spring 21 previously tensioned facilitating the return of the tilting panel 5 to its intermediate opening position (110 °), before the jack is compressed. and that the panel is returned to the initial closed position where it is applied to the sleeping frame 4.
