Definitions

  • the invention relates to a fire barrier device on a wall or ceiling passage opening of a conveyor system or the like, with a slide-like shut-off element which can be moved from an open position perpendicular to the conveying direction into a position closing the passage opening.
  • the invention has for its object to solve this problem in a fire barrier of the type mentioned with relatively simple means, but reliably to solve.
  • An essential feature of the invention is that a movable rail part bridging the rail gap during normal conveying operation is moved by the same directly or indirectly when the shut-off element is closed to a rest position which enables the passage opening to be closed in a fire-tight manner.
  • An important advantage of the invention is that no complex kinematics are required for the movement coupling between the slide-type shut-off element and the movable rail part. Rather, in most cases, a correspondingly shaped guide surface on the shut-off element is sufficient to pivot the movable rail part into the rest position.
  • the return movement of the movable rail part into the rail gap after opening the shut-off element can be effected either by gravity, by a spring or by a weight.
  • the movable rail part can be held in its normal conveying position by a holding magnet and / or other blocking elements and, after the holding magnet or the blocking elements have been triggered, fall into the rest position by the influence of gravity.
  • the shut-off element can then move freely into its closed position.
  • the movable rail part can be brought back into its conveying position by a return device connected directly or indirectly to the shut-off element.
  • An articulated coupling rod or the like can also be used for the coupling between the shut-off element and the movable rail part.
  • shut-off element is arranged in a fire-retardant frame, a relatively small receiving pocket in the interior of the frame is sufficient to accommodate the movable rail part with its lever in the rest position.
  • the invention is suitable for both horizontally and vertically movable shut-off elements.
  • a fire closure device serve to secure a passage opening 2 in a wall 1 or possibly a ceiling, through which the rails 4 of a conveyor system pass.
  • a hollow box-shaped refractory frame 12 having approximately the same passage cross section as the wall opening is suitable Way attached to the wall 1.
  • a slide-like fire-retardant shut-off element 10 can be displaced from an open position in the direction of arrow A into a closed position which closes the passage opening 2 in a fire-proof manner and on a guide rail 14 on the underside.
  • the rails 4 in the interior 13 of the frame 12 are interrupted by a rail gap 5 which is bridged during normal conveying operation by a movable rail part 16 connected to a lever 18 (in FIG. 1 and 2 shown with solid lines).
  • shut-off element 10 When the shut-off element 10 closes, it inevitably pivots the lever 18 with the movable rail part 16 about a pivot bearing 20 into a rest position indicated by dash-dotted lines in FIG. 1, for which a relatively small receiving pocket 23 is provided in the refractory frame 12. During this closing movement, a convexly curved guide surface 21 is supported on the underside of the lever 18 on an oppositely or concavely curved guide surface 11 on the front edge of the shut-off element 10.
  • the lever 18 with the movable rail part 16 falls back into its normal conveying position by gravity.
  • the guide surfaces 21 and 11 support each other.
  • a counterweight can be connected directly or indirectly to the lever 18.
  • FIG. 3 An exemplary embodiment modified compared to FIG. 1 has been broken off and cut open in FIG. 3. Since this embodiment is similar in many respects to that described above, only different details are explained below.
  • the pivot bearing 20 is below the guide bar 14 for the shut-off element 10, and the lever 18 rotatable about this pivot bearing 20 has a gripped portion 18a into which a tip 11a of the curved guide surface 11 of the shut-off element 10 can enter , when the shut-off element 10 closes (indicated by dash-dotted lines in FIG. 3). This saves space.
  • the lever 18 in FIG. 3 is provided below the movable rail part 16 fastened thereon at its free end with a roller 22 which rolls on the guide surface 11 of the shut-off element 10 when it is in the direction of arrow A; is moved into its closed position.
  • the lever 18 pivots with the movable rail part 16 in the direction of arrow B into the rest position indicated by dash-dotted lines within the receiving pocket 23 of the frame 12.
  • a tension spring 25 is tensioned between a pin 18b on the lever 18 and a similar pin within the Frame 12 is clamped.
  • This train Spring 25 relaxes when the shut-off element 10 is opened, thereby automatically pivoting the lever 18 back into the conveying position shown in solid lines in FIG. 3.
  • the conveyor system is now ready for operation again.
  • the dead weight of the lever 18 with the rail part 16 and / or an additional weight can also be used.
  • the movable rail part 16 or its lever 18 is supported by a preferably adjustable stop so that the movable rail part 16 lies exactly in line with the further rails 4.
  • the movable rail part 16 can be kept stable in the conveying position by a holding magnet, a pawl or the like.
  • the closure device according to the invention can be designed, for example, according to FIG. 4.
  • the lever 18 with the movable rail part 16 in the conveying position is held in a stable manner by a holding magnet 26 in the conveying position.
  • the shut-off element 10 does not require a special guide surface in this case.
  • the circuit for the adhesive mag is, for example, via a contact (not shown) Neten 26 interrupted, so that it releases the lever 18 so that it falls by gravity with the movable rail part 16 in the dash-dotted rest position within the receiving pocket 23 of the frame 12.
  • a return device 28 coupled to the shut-off element 10 ensures that when the shut-off element 10 is opened, the lever 18 with the movable rail part 16 is pivoted back into the conveying position shown in solid lines in FIG .
  • the pivoting lever 20 for the lever 18 with the movable rail part 16 can also be attached to the wall 1 or a ceiling outside the frame 12.
  • the shut-off element 10 can be moved from its lower open position shown in FIG. 5 in the direction of arrow A in running rails 34 to its upper closed position.
  • the here angular lever 18 with the movable rail part 16 is articulated via a coupling rod 33 to the shut-off element 10 and is inevitably in the closing movement of the shut-off element 10 about its pivot bearing 20 in the receiving pocket 23 of Frame 12 moved into it.
  • This pivoting movement in the direction of arrow B leads to the rest position of the movable rail part 16, indicated by dash-dotted lines in FIG. 5.
  • shut-off element 10 In its open position, the shut-off element 10 is fixed by means of an anchor plate 27 through the holding magnet 26 fastened to the frame 12 by means of a fastening bracket 29.
  • shut-off element 10 is provided in the region of the running rails 34 with recesses 36 in which Luafwagen 35 are fastened, which engage slidably in the running rails 34 and guide the shut-off elements 10.
  • the frame 12 of the fire barrier is laterally double-walled, between two webs 42 insulating cavities 43 are formed, in which there are fastening screws 45 with which a base plate 40 of the frame 12 on the wall 1 or Ceiling is attached.
  • FIGS. 5 and 6 Another special feature of the frame 12 shown in FIGS. 5 and 6 is that its outer cover plate 41 can be opened easily and quickly for maintenance and assembly purposes if necessary.
  • the mechanism required for this opening is within the frame 12 ge protects arranged and consists on one side of hinges 47 and on the opposite side of at least one lock 48 which can be actuated via an actuating hole 49 in the outer web 42, for example by means of a suitable tool.
