Definitions

  • the invention relates to a push-up device for roller shutters and roller shutters with a roller shutter curtain which can be wound up on a shaft and consists of roller shutter slats which are connected to one another in an articulated manner, wherein a multi-unit suspension for the roller shutter curtain is provided on the shaft from elements which are connected to one another in an articulated manner.
  • DE-OS 23 03 025 shows an embodiment for producing a form-fitting jamming of the roller shutter slats which are articulated to one another, blocking members being fastened to the longitudinal sides of the roller shutter slats, which mutually automatically when the slats are pressed together by pushing a tab into a U-shaped guide lock and at the same time block the slats with each other in their rotational and longitudinal movement.
  • the disadvantage here is that the blocking members are complex and can only be attached to the ends of the slats, so that no rigid slat wall can be achieved with larger shutter widths.
  • roller shutter slats are specially designed so that when they are pushed together they lock themselves and can no longer twist each other.
  • this profile-dependent solution to the problem only special roller shutter slats with additional stops can be used, which makes roller shutter manufacture disproportionately expensive.
  • DE-OS 24 05 078 is based on securing roller shutters made from commercially available roller shutter slats by arranging special locking elements in the lower receiving groove of the roller shutter slats against displacement of the roller shutter slats against one another and also against twisting or tilting in the closed state.
  • the locking elements are depending on the shutter width arranged at the ends of the roller shutter slats or at equal intervals across the entire roller shutter width.
  • the disadvantage is that a large number of such locking members are required, which have to be inserted into corresponding recesses in the webs of the slats when the individual roller shutter slats are pushed together to form the roller shutter curtain and must be fixed by gluing or pinning.
  • roller shutters or roller doors are secured against being pushed up by a suspension for the roller shutter curtain consisting of three different elements.
  • the elements which consist of two sheet metal strips which are doubled one on top of the other, are connected to one another in the manner of link chains by means of articulated eyes, and each element has a tongue which overlaps the articulation and projects into the region of the neighboring element.
  • the locking device is especially designed for heavy roller shutters and roller doors with a geared motor drive, which safely reaches the end position in the extended position.
  • a stop adjuster in the form of an additional spring is required for a roller shutter with a belt roller.
  • DE-OS 41 08 423 describes a joint piece which is arranged between the roller shutter curtain and the shaft, and with the aid of which a positionally stable locking of the shaft against pushing up the roller shutter curtain from the outside is sought.
  • the joint piece consists of an upper element fastened to the shaft, a middle element which is pivotably connected to the upper element and a further lower element; On the lower element there is the suspension rail for the top slat of the roller shutter curtain.
  • a nose projects out of the upper element, which represents a stop and limits the pivoting movement of the central element against the upper element.
  • the lower element With the help of a manually adjustable adjustment device on the middle element, the lower element is aligned by swiveling downward about the central axis of rotation.
  • the joint piece then functions like a straight locking rod directed towards the middle of the shaft, the clamping effect between the individual elements being achieved by the projecting lugs and the manually operated adjusting device.
  • a three-part suspension is provided on an electrically operated roller shutter, the ends of the outer links being able to engage in a form-fitting manner in the two ends of the middle link and being inserted into them in the lowered state of the roller shutter curtain. This creates a rigid connection between the tank and the shaft. The positive connection is released if the links are pulled apart against spring pressure when the roller shutter is wound up.
  • the invention has for its object to develop a push-up device for roller shutters and roller doors, which is arranged as a suspension for the roller shutter curtain between the roller shutter curtain and the roller shutter shaft and consists of several elements, the individual elements aligning so that the suspension itself when pushing up the roller shutter curtain behaves like a rigid rod.
  • the elements of the suspension comprise locking members and a coupling member, that the locking members and the coupling member have a nose at the upper end and the locking members also have an indentation at the lower end, and that the lugs of the coupling member and the locking members in engage the associated indentations of the adjacent locking members.
  • the advantages achieved by the invention are, in particular, that the elements of the anti-lift device are simple in design and can therefore be produced inexpensively as extruded profiles.
  • the anti-lift device is easy to assemble and can easily be used for any roller shutter.
  • FIG. 1 shows a perspective view of a push-up safety device according to the invention
  • FIG. 2 shows a side view of the exemplary embodiment from FIG. 1.
  • the anti-lift device consists of a multi-unit suspension 7 for the roller shutter curtain 4 on the roller shutter shaft 5.
  • the suspension 7 is composed of a combination of two different types of elements 1, 6 which are connected to one another in an articulated manner: preferably three locking members 1 and a coupling member 6, the number of locking members 1 depending on the size of the roller shutter box 17 and the bale diameter of the wound roller shutter.
  • the uppermost locking member 1 is rotatably fastened by means of a suspension bolt 10 to two rings 8 pushed onto the shaft 5, while the connection between the lowest locking member 1 and the roller shutter curtain 4 produces the coupling member 6; the uppermost lamella 16 of the roller shutter curtain 4 is suspended in a known manner in a hook 14 at the lower end of the coupling member 6.
  • FIG. 3 and FIG. 4 show individual representations of a coupling member 6 and a locking member 1 in a side view.
  • Both links 1, 6 are arched and easily manufactured as extruded profiles.
  • the upper end of the links 1, 6 is designed as a pivot bearing 12, the outer end of which is shaped into a nose 3; in addition, the locking member has an indentation 2 at the lower end immediately in front of the rotary bar 13 assigned to the rotary bearing 12 (FIG. 4).
  • sections of the suspension 7 are each shown schematically in a side view.
  • the cutouts show the rotatable connection between two locking members 1 with the roller shutter pulled up, wound onto the shaft 5 (FIG. 5a) and with the roller shutter lowered (FIG. 5b).
  • the arcuate members 1, 6 of the suspension 7 nestle by appropriate Rotation of the links 1, 6 in the pivot bearings 12 on the shaft 5.
  • Recess 2 and nose 3 of adjacent links 1, 6 strive apart and form a wide opening 15 (Fig. 5a).
  • FIG. 6 shows an exemplary embodiment of an advantageous development of the invention in the same representation as in FIG. 2.
  • the coupling member 6 is provided on the outside with a notch 9 at the lower end.
  • the notch 9 of the coupling member 6 engages in a stop 11 attached to the wall 18 and blocks the roller shutter from being pushed up.
  • This embodiment of the invention avoids the vertical loading of the roller shutter shaft 5, as occurs when the suspension 7 is jammed in the first embodiment of the invention.
  • Fig. 7 shows a side view of the coupling member 6 according to the advantageous development of the invention with the notch 9 at the lower end.
