Definitions

  • the present invention relates to an elevator door leaf, an elevator door having such an elevator door leaf, and a method of manufacturing such an elevator door leaf.
  • Elevator doors usually consist of a number of door leaves, which in turn can be formed single or multi-shell. When making these door panels, the various safety requirements placed on elevators and lift doors must be taken into account.
  • door leaves for elevators are formed einschalig.
  • the used door leaves which are regularly made of sheet metal, are provided on the front sides with stiffening profiles.
  • the joining of the stiffening profiles with the door leaf is done by welding.
  • the connection can also be made by riveting, screwing or gluing.
  • the publication DE 690 17 299 T2 describes a telescopic elevator door assembly having a high speed door and a low speed door with each door suspended from a pair of spaced apart roller assemblies and the roller assemblies running along a single common path.
  • Each of the doors may be formed of a panel having six rectangular bending edges, two of which form a vertical U-shaped channel extending along a side edge of the panel, four of which have a vertical column of rectangular cross-section along the opposite side edge form the panel, wherein the column adjacent to a corner is open, so that the U-shaped channel of a door can engage in the pillar of the other door.
  • a door segment having a substantially rectangular cross-section which is formed by two main wall sections and two side wall sections.
  • To simplify the manufacture of the door segment is composed of two parts, each having a main wall portion and can be coupled together by integrated snap elements.
  • the door segments consist of sheet metal parts that have been formed by bending.
  • a two-shell elevator door leaf with a first shell to be arranged on the floor and a second shell to be arranged on the shaft side is from the document EP 1 403 204 A1 known.
  • This elevator door leaf is to be manufactured from the two shells mentioned by pushing together these two shells in the longitudinal and / or transverse direction, wherein one of the two shells in the region of a folded over the other shell comprises or surrounds.
  • the document D2 ( FR 2 686 277 A1 ) relates to a method for producing an enameled container for an oven.
  • a sheet is to be folded as a starting material on one side at small intervals twice, so that the container has two mutually perpendicular oriented side surfaces to form the bottom and a side wall, which are arranged in the region of twice made folding L-shaped ,
  • the elevator door leaf according to the invention provides that in the region of at least one edge a double substantially C-shaped folded edge is provided. This double fold gives the door leaf a high stability and can be introduced, for example. By manual bending. This offers advantages not only in terms of logistics and warehousing but also in the production, while the production with multiple parts, these must be positioned and held each other.
  • the double fold is essentially C-shaped.
  • This C-shape offers high stability and can be achieved simply by bending the sheet. This bending can be done by machine or manually.
  • a material for the door leaf is usually sheet metal, such as. Stainless steel or black plate, used. Even a galvanized sheet can be used.
  • a cladding sheet be provided to both adapt the appearance of the requirements and to effect a sufficient noise insulation.
  • This cover can be made of different materials, preferably a stainless steel sheet is used. Alternatively, aluminum, glass, plastic or wood can be used.
  • edge protection may be provided in the region of at least one edge of the elevator door leaf. This edge protection can be done by bending the sheet to avoid sharp edges, so that the risk of injury is reduced.
  • a perforation is provided in a bending area.
  • the perforation or perforations indicate the exact positions at which the material of the door leaf is to be bent.
  • the perforations are introduced by punching.
  • a fastener such as a Screw or Verklipsung be provided.
  • a fastener such as a Screw or Verklipsung be provided.
  • the material can also be riveted.
  • a rivet connection, welding and / or another suitable connection element may be provided.
  • At least one hole can be provided in the upper area of the lift door leaf for fastening the door leaf, and a double fold around in the lower area for attaching at least one door leaf guide.
  • a carriage is used, on which the door leaf can be attached.
  • an elevator door leaf with a number of folds is provided, in which a perforation is provided in the area of at least one of the folded edges in a bending area.
  • This perforation which is introduced, for example, by punching, allows a simple, positionally accurate bending without much effort, so that the bending can also be performed manually without machine use.
  • the elevator door according to the invention comprises at least two elevator door leaves of the type described above.
  • the door leaves for opening and closing the door can be rectified or moved in the opposite direction.
  • a labyrinth is formed in the elevator door at least in the closed state between two of the elevator door leaves.
  • This labyrinth is regularly provided in fire resistance doors and is, for example, achieved in that the trailing edge of the door panel is designed so that it is formed in the closed state with a frame or a second door leaf.
  • the inventive method is used to produce a described elevator door leaf, wherein the shell or the material of the door leaf is bent in the region of a perforation to make a folded over.
  • FIG. 1 a door leaf according to the prior art is shown, which is generally designated by the reference numeral 10.
  • This door leaf 10 which is formed as a single shell, is made of a flat material and comprises a front edge 12 folded as C and a trailing edge 14 folded as a C, and the illustration also shows a frame 16 which interacts with the door leaf 10. Instead of the frame 16 may also be provided a second door leaf.
  • FIG. 2 shows another known door leaf 20, which has an increased rigidity.
  • This door leaf 20 comprises a front edge 22 folded as C and a trailing edge 24 folded as C.
  • the illustration also shows in turn a frame 26 which cooperates with the door leaf 20 so that a labyrinth 28 is formed in the closed state.
  • a stiffener 30 is provided in the region of the rear edge 24, which is introduced by bending over the material or the sheet metal of the door leaf 20 in the region of the trailing edge 24 becomes. Although this stiffener 30 gives the door leaf 20 increased strength, which is regularly not sufficient.
  • FIG. 3 a further door leaf 40 according to the prior art is shown, which in turn has a canted edge C edge 42. In this case, however, the door leaf 40 is only bent over in the region of the trailing edge 44. Furthermore, in turn, a frame 46 and between the frame 46 and the door panel 40 in the region of the trailing edge 44 formed labyrinth 48 can be seen.
  • an additional sheet metal bracket 50 is attached to the trailing edge 44 of the door panel 40. With this additional sheet metal angle 50 sufficient strength can be achieved. Thus, it is no longer necessary even with elevator doors with large width for stability reasons, to install additional stiffening profiles.
  • a disadvantage of the door leaf 40 according to the prior art is that an additional part, namely the sheet metal angle 50, is required. This is, for example, in the manufacture of disadvantage, since in this the metal bracket 50 must be positioned to the door panel 40.
  • FIG. 4 is a possible embodiment of a door leaf, indicated generally by the reference numeral 60, shown in a schematic representation.
  • This door leaf 60 also includes a front edge 62 shaped as C.
  • the trailing edge 64 which is likewise C-shaped, gives the door leaf 60 sufficient stability.
  • a frame 66 is shown which defines a labyrinth 68 with the trailing edge 64 of the door panel 60.
  • the trailing edge 64 is produced by double edging of the material or the sheet of the door leaf 60.
  • the trailing edge is formed with an upper leg 70 and a lower leg 72.
  • the lower leg 72 is formed by the double fold, i. by a Umbantung by 180 °, a double thickness, since in this area the sheet used is present twice. That in this area, there is a reinforcement or stiffening, since the material of the door panel 60 is given twice.
  • the double edge there are two layers or layers of the material or sheet used.
  • the illustrated door leaf 60 has a high strength and can be made or folded from a single piece of sheet metal.
  • the "double" C-edge increases the stiffness. It should be noted that no additional fasteners or sheet metal parts are necessary.
  • "Double" C-edge means that the C-shaped trailing edge is formed by two C's, an upper C and a lower C.
  • the material of the door leaf 60 may have a perforation, which can not be seen in this illustration. In this way, the edge or the bending process can be carried out easily and manually. The use of a machine is not required.
  • the position of the bending edge 74 is to specify exactly.
  • FIG. 5 is another embodiment of the door panel, indicated generally by the reference numeral 80, shown.
  • This door leaf 80 which is made of a sheet-metal sheet material, comprises a C-shaped front edge 82 and a double C-shaped trailing edge 84 having an upper leg 86 and a lower leg 88.
  • the illustration shows that the lower leg 90 of the front edge 82nd a folded edge 92 and the upper leg 86 of the trailing edge 84 also has a folded edge 94.
  • This Umkanteptept 92 and 94 serve as edge protection and are therefore provided for security reasons. In principle, care is taken to ensure that all edges, for example by means of suitable cladding, are outside the field of view.
  • FIGS. 6 and 7 illustrate the production of a door leaf 100 having a front edge 102 and a trailing edge 104.
  • a bending edge 106 in the direction of an arrow 108 by about 180 °, the double C of the trailing edge 104 is achieved with the double lower leg 110.
  • the door leaf 100 has a perforation in the region of the bending edge 106. Such perforations may also be provided at other locations provided for edge-bending.
  • a door panel 120 comprising a C-shaped leading edge 122 and a double C-shaped trailing edge 124 having an upper leg 126 and a lower leg 128.
  • a fastening element 130 in this case a screw 130, is provided.
  • This screw 130 fixes the two superimposed layers or layers of the material of the door leaf 120 to each other, so that they are no longer free-sliding, ie, mutually displaceable, are. In this way, an increased resistance moment is achieved, which corresponds approximately to the moment of resistance of a sheet of double wall thickness.
  • FIG. 9 shows on the left side another door panel 140 according to the invention with a front edge 142 and a trailing edge 144, wherein the section enclosed by a circle 146, namely the trailing edge 144, is reproduced enlarged on the right side of the illustration.
