Definitions

  • the invention relates to a fire protection closure for conveyors with a closure plate which closes an opening.
  • Fire protection closures are known in which the closure plate is designed as a slide.
  • devices are provided which fold away or submerge conveyor track parts for a conveyor track penetration. This means that only short conveyor track gaps are required, and there is no risk of opening when there is pressure or impact, but these fire protection closures have the disadvantage of requiring a large amount of space. It is therefore necessary to design the designs as vertically falling or lifting closing slides. It is also possible for the slides to be moved laterally to the right or left. In addition, longer rails are required to guide the slide, which can easily become dirty and thus lead to malfunctions.
  • closure plate is a flap in the case of fire protection closures, wherein devices can also be provided for conveying path penetration that fold away or submerge the conveyor track parts.
  • fire protection closures have the advantage that only a small space is required and only one version is required for wall and ceiling openings.
  • the pivot bearings of the flap are also superior to the longitudinal guides on slides.
  • Such fire protection closures have the disadvantage, however, that a Ge with respect to the changing closing torque weight compensation is required.
  • there are often only small locking forces in the closed state so that additional devices are required.
  • it is disadvantageous with the flaps that relatively long conveyor track sections have to be moved away when the fire protection closure is closed.
  • the present invention is therefore based on the object of making a new type of fire protection available, which has the advantages of a flap, namely a small space requirement and a movement in pivot bearings, with the advantages of a slide, the retraction of the free side of the closure plate into a pocket to prevent unwanted opening connects with the need for only short conveyor track gaps and can also be used universally on walls or ceilings.
  • the invention consists in that the closure plate is fastened to one or more displaceable rotary bearings for opening or closing in such a way that a rotary movement is followed by a linear movement for opening, while a linear movement follows when a rotary movement is closed.
  • a fire protection closure represents a basic construction that can be used anywhere, in which only a few adaptations are required when used for a fire protection closure on a wall or ceiling. It does not matter whether the installation is carried out with the frame resting on it or whether it is installed in the wall or ceiling opening with a frame designed accordingly. Otherwise, there is no difference between a planned closed or open fire protection version.
  • the side of the closure plate opposite the bearing can be moved into a box-like pocket at the end of the closing process and removed at the beginning of the opening process.
  • the linear movement of the closure plate serves to move conveyor track parts from their operating position into a pocket.
  • An advantageous embodiment consists in particular in that a bracket extending to the opposite side of the closure plate is attached to the movable bearings of the closure plate, which carries the conveyor track parts, the box-like pocket is movable to penetrate the conveyor track in front of the closure plate.
  • the console is guided displaceably similar to the bearing of the closure plate.
  • closure plate can be secured in its closed position by a holding device.
  • a weight-driven, rotatable lid is provided on the pivot bearing side, which rests on the open closing plate and also rests on it during the closing process, so that the space released by the closing plate is covered.
  • the closure plate can also carry a track cover which projects above the closure plate and projects above the raceway in the open position, but covers the latter in its end region in the closed position of the closure plate.
  • An expedient embodiment of the invention is that one or two drives are arranged in the area of the fire closure frame, which have a drive application point arranged in relation to the center of gravity and the locking plate pivot bearings in such a way that first a rotary movement and then a linear movement when closing or vice versa when opening he follows.
  • additional weights can optionally be attached to levers on the closure plate in order to generate compensating or counteracting torques.
  • the drive expediently consists of a pneumatic, hydraulic or motor-operated thrust drive which, when arranged in a fixed manner, effects the pivoting or pushing movement or which rotates itself bar mounted together with the rotatable and slidable locking plate represents the articulated drive itself.
  • a useful embodiment is that the linear drive of a link guide and this moves a backdrop attached to the flap.
  • closure plate is divided and consists of a flap element for the rotary movement and at least one slide element which carries out a linear movement.
  • a slide element provided above the flap element and a slide element arranged below the flap element are advantageously connected to one another for weight compensation, preferably by means of a cable pull guided over rollers.
  • a fire protection closure which closes an opening 2 with a closure plate 1, which is provided in a wall 3.
  • the closure plate is mounted in a pivot bearing 4, so that during the closing process the closure plate 1 performs a rotary movement, as shown by the arrow 6, until the plate comes to rest on the wall 3 and takes the dot-dash position 7.
  • This rotary movement is followed by a linear movement, in which the rotary bearing 4 is moved into the position 5 by the linear movement, which is represented by the arrow 8.
  • This movement takes place by means of a pneumatically or hydraulically operated cylinder piston arrangement 10, which is fastened to the closure plate 1 via a schematically illustrated connection 11 with an articulation point 12.
  • a pneumatically or hydraulically operated cylinder piston arrangement 10 which is fastened to the closure plate 1 via a schematically illustrated connection 11 with an articulation point 12.
  • the articulation point 12 takes up position 13 and at the end of the linear movement position 14.
  • a corresponding adaptation of the position of the piston 10 to the movement of the closure plate 1 is made possible by a joint 15, to which the piston 10 is connected at a retaining web 16.
  • FIG. 2 shows a corresponding fire protection closure in which the closure plate 1 linearly on the wall in the pocket 9 from below after its rotation is shifted upwards.
  • ent 2 speaks in terms of construction and in the manner of operation of the fire protection closure according to FIG. 2 by the closure plate 1 executing a rotary movement according to arrow 6 by actuating the cylinder piston arrangement 10, followed by a linear movement according to arrow 8, to bring the closure plate 1 into its final closed position on the wall 3 at the end of the opening 2.
  • the closure plate 1 of the fire protection closure is opened both according to FIG. 1 and according to FIG. 2 moves linearly out of the pocket 9 in the opposite direction to the arrow 8, and a rotational movement in the opposite direction to the arrow 6 follows until the closure plate 1 assumes the position shown in the figures.
  • a fire protection closure is shown, which is arranged on a ceiling 23, in which there is an opening 22 which can be closed with the aid of the closure plate 1.
  • the closure plate 1 is shown in its open position, in which it is articulated at D.
  • the closure plate is given a rotary movement via a schematically illustrated piston rod 11, which is articulated on a web 17 at A, so that the closure plate assumes the dot-dash position 7 on the wall 23.
  • the pivot point of the closure plate 1 assumes the position shown at A '.
  • the linear movement as a result of which the closure plate 1 or 7 is pushed into the pocket 9.
  • the point of articulation of the piston rod 11 on the web 17 is at "A"
  • the point of articulation of the closure plate 1 has moved from position D to position D ".
  • a fire protection closure is shown, which is arranged under the ceiling 23 and serves to close the opening 22 in the ceiling 23 with the aid of the closure plate 1.
  • the arrangement and closure process largely correspond to FIG. 3, again the closure plate 1 is pivoted by the piston-cylinder arrangement into the position 7 shown in dash-dotted lines in contact with the wall 23, the articulation point A of the piston rod on the web 17 of the closure plate 1 assuming the position A ', while subsequently during the linear movement through which the closure plate 1 or 7 is moved into the pocket 9, the articulation point of the piston rod moves from A 'to A ", while the rotary bearing of the closure plate 1 moves from position D at the beginning of the linear movement to position D" at the end of the linear movement.
  • FIG. 5 shows a fire protection closure with a conveyor track 31 in the closed position.
  • the closure flap 1 was pivoted from the open position, as explained for example in connection with FIG. 1, into contact with the wall 3 and then moved into the pocket 9 by a linear movement, the rotary bearing 4 of the closure plate 1 moving into the position 5 moved with.
  • a bracket 34 is attached to the displaceable bearings 4 of the closure plate 1 via struts 33, which supports the conveyor track parts 32, which during the closing process of the closure plate 1 from the conveyor track 31 must be moved away.
  • the bracket 34 is guided in bearings 35 similarly to the bearings 4 of the closure plate 1. If, by actuation of the cylinder-piston arrangement 10, which can be seen from FIG.
  • the console 34 is simultaneously moved into the pocket 9 and thus also the conveyor track parts 32 arranged on it are inserted into the pocket 9.
  • one or preferably on both sides two cylinder piston assemblies 10 may be provided.
  • a weight 36 is additionally fastened to the closure plate 1 via the web 17 in order to support the closing movement of the closure plate 1 which is eccentrically suspended or mounted for constructional reasons by means of the generation of corresponding torques.
  • Additional locks can be provided to ensure that one movement is completed before the other type of movement is possible.
  • a cover 37 is arranged, which is rotatably supported at 38 and is driven by a weight 39 such that it rests on the open closure plate 1 and also at 5 is in the closed position on the closure plate 1, so that the space 40 released by the closure plate is covered.
  • raceway cover In order to avoid the more complex cover 37, it is also possible for a raceway cover, not shown, to be attached to the closure plate 1.
  • This track cover protrudes above the closure plate 1 and projects in the open position of the closure plate over the track, but covers this in its end region according to the cover 37 when the closure plate is in the closed position.
  • the closure plate 1 With a vertical arrangement of the fire protection closure, in which the closure plate 1 can be moved by gravity, it can be held in position by holding magnets. It is possible to control the sequence of movements of the closure plate 1 during the closing process by switching the holding magnets accordingly.
  • Fig. 7 a modified embodiment of a fire protection closure is shown, in which the Closure plate 1 is divided and consists of a flap element 1a for the rotary movement and a slider element 1b arranged above the flap element 1a and a slider element 1c arranged below the flap element 1a.
  • the rotary and linear movement to be carried out by the closure plate is broken down into a rotary movement which the folding element 1a carries out and a linear movement which is carried out by the slide elements 1b and 1c.
