Definitions

  • the present invention relates to a hot gas and fume venting device, particularly for emergency situations.
  • Venting devices of this kind are already known and are used for closing a skylight. They comprise a shutter which is articulated about a horizontal axis and is overturned from a closed position into an open position by means of a pair of jacks. One of these jacks produces partial opening up to approximately 90° and the other one completes the opening action beyond 90°.
  • a principal aim of the present invention is therefore to provide a venting device that is capable of obviating the constructive complexity of known devices.
  • NL-A-75 01 949 discloses a venting device which includes the combination of features of the precharacterizing portion of the appended claim 1.
  • the venting device comprises a rectangular shutter 1 which is pivoted about a horizontal axis A to a frame 2 that surrounds an opening 3.
  • the opening 3 is formed in the ceiling of a room to be monitored, for example a kitchen.
  • the venting device can of course be applied to any kind of room.
  • a beam 4 The ends of a beam 4 are fixed to the longitudinal walls of the frame 2; said beam is composed of a pair of parallel spaced longitudinal members 5.
  • a hydraulic/pneumatic jack 6 of the multiple-rod or telescopic type is pivoted between the longitudinal members 5.
  • the jack 6 comprises a first outer cylinder 7 which is closed at one end by a bottom 8 and has, at the opposite end, a ring 9 provided with two coaxial pivots 10 and 11 for articulation in the beam 4.
  • a second cylinder 12 is slideable within the cylinder 7 and is closed at one end by a bottom 13; the opposite end of said second cylinder protrudes beyond the ring 9, and a collar 14 is centered therein.
  • a chamber 15 is formed between the bottoms 8 and 13; by means of a channel 16 formed in the bottom 8, said chamber is connected to a pipe 17 that runs outside the cylinder 7.
  • the opposite ends of the pipe 17 are sealingly inserted in seats of the bottom 8 and of the ring 9, and the pipe is connected to a passage 18 that passes axially through the pivot 11 to be connected to a source of compressed air, as will become apparent hereinafter.
  • a third cylinder 19 is slidingly accommodated inside the cylinder 12, and one end of said third cylinder is guided in the collar 14, whereas the opposite end is closed by a sort of cup 20 which is screwed on said end and sealingly guided inside the cylinder 12.
  • the cup 20 has, at its center, a cylindrical raised portion 21 that protrudes into a recess 22 of the bottom 13 so as to form, together with said bottom, a chamber that is connected to the chamber 15 by means of a hole 23 formed in the bottom 13 and to the inside of the cylinder 19 by means of a hole 24.
  • a rod 25 is screwed into the raised portion 21, lies coaxially to the cylinder 19, and supports a piston 26.
  • the piston 26 is sealingly slideable within a fourth cylinder 27 which is guided inside the cylinder 19 and has an end that protrudes outside the cylinder 19 and is closed by a plug 28.
  • a bushing 29 is applied to the opposite end of the cylinder 27, sealingly slides within the cylinder 19 on the outside, and sealingly slides over the rod 25 on the inside.
  • the plug 28 has a threaded stem 30 that allows to apply a body for articulated coupling to a median point of a cross-member 31 that connects the two longitudinal rails of the shutter 1.
  • the piston 26 divides the inside of the cylinder 27 into two chambers containing a pneumatic/hydraulic fluid, for example CO 2 gas and oil.
  • the two chambers 32 and 33 are mutually connected by means of a gauged hole 34 (see figure 4) and a check valve 35 of the type constituted by a ball 36 which is pushed by a spring 37 and closes a hole 38 that passes axially through the piston 26.
  • the valve 35 is orientated so as to close the hole 38 when the pressure in the chamber 32 is higher than the pressure in the chamber 33.
  • a bottle 39 of a compressed gas for example CO 2
  • a hot gas and/or fume sensor 40 is installed on a bracket 41 that joins, in an upward region, the longitudinal members 5 that compose the beam 4.
  • a pneumatic cylinder 42 is also mounted on the bracket 41 and is connected in series to the jack 6; the rod 43 of said pneumatic cylinder is adapted to engage like a sliding bolt in an eyelet 44 located on the cross-member 31.
  • a pivot 45 guided in the frame 2 and provided with a knob that can be accessed from outside is associated with the pneumatic cylinder 42.
  • the pivot 45 is aligned with the rod 43 and can be operated manually to release the rod 43 from its engagement position in the eyelet 44 during periodic inspections or in case of failure of the venting device in emergency situations.
  • venting device The operation of the described venting device is as follows. In normal conditions, the shutter 1 rests on the frame 2 and is closed by the engagement of the rod 43 in the eyelet 44.
  • the sensor 40 detects this anomaly and activates the opening of the bottle 39.
  • the compressed gas thus released activates first of all the cylinder 42, releasing the shutter 1, and then the telescopic jack 6. Accordingly, the compressed air, after entering the chambers 15 and 22, causes the extension of the cylinders 12 and 19 and the extension of the jack until the shutter has rotated beyond 90°.
  • the shutter is overturned into the closed position by acting manually.
  • the transfer of fluid from the chamber 33 into the chamber 32 during the retraction of the jack is facilitated by the opening of the valve 35.
  • venting device fully achieves the intended aim and objects.
  • the use of a telescopic jack allows considerable simplification in construction and assembly and therefore allows better adaptability in applying the venting device to the various types of shutter, from rectangular ones to circular ones, with flat or cambered dome-shaped glazed panels.
