Definitions

  • the invention relates to a fire or smoke protection curtain with (a) a textile fire protection element having a first side in the form of a front and a second side in the form of a back, in a compact bearing assembly and a protection arrangement in which there is the spread of a fire and / or opposes smoke, is engageable and extends in the protective arrangement along a closing surface, and (b) at least one guide rail which guides the fire protection element when the fire protection element is in the protective arrangement and for applying a holding force corresponding to bulging of the Fire protection element counteracts, is formed.
  • Such fire or smoke curtains are used to inhibit the spread of smoke and / or fire. Often fire or smoke curtains are used to close an opening in a wall in case of fire. If a compressed air difference arises between the front side and the rear side of the fire protection element, the at least one guide rail must apply a holding force. The holding force therefore counteracts excessive bulging of the fire protection element.
  • the back is, for example, the wall side of the fire protection element.
  • a fire or smoke curtain which is arranged in front of a door and in which a ballast strip on the foot portion of the fire protection element is used to pull the fire protection element in case of fire down in front of the door.
  • the baseboard and the fire protection element run in an S-shaped guide rail.

In other words, if one looks along the fire protection element, guide rails according to the prior art always have to see part of the guide rail on both sides of the fire protection element. In the case of a guide rail according to the invention, only part of the guide rail has to be on one side of the fire protection textile be seen. It should be noted that it is also possible that the fire or smoke curtain has more than one guide rail. In particular, it is advantageous that the guide rail can be built flat. The holding force is preferably applied from the wall side to the fire protection element.

  • the fire protection element 14 has in this embodiment a holding element 70 in the form of a rivet 71. On the holding element 70 of the projection 72 is formed, which is prevented by the support edge 38 from slipping.
  • the fire protection element 14 consequently has a lower flexibility in the region of the coupling section 36 and has the projection 72 there.
  • the protrusion 72 interacts with the support edge 38 and the increased stiffness and / or lesser flexibility prevents the coupling portion 36 from slipping out through the slot 34.
  • FIG. 8 shows that the fire protection element 14 has a plurality of rivets 71.1, 71.2, ..., on each of which a projection 72.1, 72.2, ... is formed.
  • the rivets 71 in the direction of the rear side 46 have a projection height h 46 .
  • This is preferably between 0.5 mm and 7 mm. It is possible, and represents a preferred embodiment, that the projection height h 44 in the direction of the front side 44 corresponds to the projection height h 46. Alternatively, for example, the projection height h 44 in the direction of the front side 44 may be smaller than the projection height h 46 .
  • the sum h 46 + h 46 from both projection heights is not more than 8 mm, in particular 7 mm.
  • FIG. 9 shows the fire protection element 14 in the embodiment according to FIG. 6 .
  • the envelopes 67.1, 67.2 have interruptions 74.1, 74.2,.... These interruptions, which represent a preferred embodiment, cause the fire protection element 14 more easily on a winding shaft 24 (see. FIG. 1 ) can be wound up.
  • FIG. 10a shows a guide rail 20 of a fire or smoke protection curtain according to the invention.
  • the guide rail 20 has an end face 76.
  • the end face 76 is that surface which can be seen when looking parallel to the closing plane S of the fire protection element 14 on the guide rail 20.
  • the face 76 can theoretically be divided into area 77.1, 77.2, 77.3 and / or area quartiles 78.1, 78.2, 78.3, 78.4, wherein all area quartiles are the same width and together give the full width of the face 76.
  • the first surface area 77.1 and the first area quartile 78.1 are adjacent to the wall 12 to which the guide rail 20 is attached.
  • the closing surface S extends in the outermost surface center 77.3 of the end face 76 through the end face 76. In the present case, the closing surface S extends through the end face 76, even in the outermost surface quartile 78.4. In other words, the guide rail 20 according to the invention does not require the installation space which would extend beyond the last surface 77.3 of the prior art guide rails Wall 12 seen from the guide rail is so behind the closing surface or closing plane S significantly thinner than before.
  • the second support portion 54 of the guide rail 20 has in this case a first portion 80.1, which extends along the guide surface E 54 , and a second portion 80.2.
  • the support edge 40 separates both sections 80.1, 80.2 from each other.
  • the second section 80.2 extends at an angle to the guide surface E 54 .
  • an angle ⁇ between the guide surface E 54 and the extension direction of the second partial section 80.2 is 15 ° to 45 °, in the present case approximately 30 °.
  • the second support section 54 yields particularly little. The projection 72 is therefore held securely on the support edge 38.
  • FIG. 10b shows the guide rail 20 according to FIG. 10a , wherein the tensile force Fs was applied to the fire protection element 14. It can be seen that the slot 43 tapers by the tensile force Fs. The tensile force Fs causes only those parts of the guide rail to move in the direction of the tensile force that is in the first half space 39. In the present case, this is the sheet on which the support edge 38 is formed. The sheet with the support portion 54 does not move in the direction of the tensile force but slightly in a direction perpendicular thereto.
  • FIG. 10c shows a further embodiment of a guide rail 10 and a fire protection element 14 of a fire or smoke protection curtain 10 according to the invention. It can be seen that the projection 72 is formed in this embodiment on a holding element 70.
  • FIG. 10c also shows in detail the forces acting.
  • the projection 72 presses on the support edge 38.
  • the support edge 38 exerts the support edge force 38 on the projection 72.
  • the coupling section 36.14 exerts the coupling section force F 36 on the guide rail 20, in the present case on the second support section 54.
  • the feature that the old force is received at least predominantly from the support edge 38 is understood in particular to mean that
  • FIG. 11 a shows an embodiment in which the projection as in the FIGS. 6 and 7 is formed on holding elements 70.
  • the protrusion height h 46 (see FIG. Fig. 8 , upper partial image) greater than the projection height h 44 . This has the consequence that the holding member 70 abuts with the part on the support edge 38, the projection height is greater.
  • FIG. 11b shows the guide rail according to FIG. 11a in another perspective view.
  • FIG. 12a shows a further embodiment of a guide rail 20 of a fire or smoke protection curtain according to the invention, which has a piping 82 in the form of a Kederstange.
  • the fire protection element 14 extends in its coupling portion 36 around the piping 82 around.
  • the holding force F H is applied by the support edge 38.
  • the Kederstange 83 holds the lateral edge of the fire protection element 14 in the guide rail 20 and is arranged in the guide rail 14, that the cross-sectional area A of the Kederstange 83 completely on the side of the back 46, here the wall side of the fire protection element 14.
  • the cross-sectional area A is also completely on the wall-side side of the closing surface S, which here is a closing plane.
  • FIG. 12b shows a further embodiment of the invention, which differs from the otherwise identically constructed embodiment according to FIG. 10c characterized *** in that the keder bar 82 causes the projection 72 to be formed. Although a part of the guide rail 20 extends in the second half space 41, but these components do not absorb the holding force.
  • FIG. 12c shows a further embodiment in which a plurality of retaining elements 70 is present, of which only the retaining element 70.1 is located.
  • the holding elements have a concave lateral surface which cooperates with the support edges 38, 40 in a form-fitting manner.
