Definitions

  • the invention relates to an automatic roller shutter protection against pushing up the roller shutter curtain from profiled bars which are guided in U-shaped rails and are limitedly displaceable against each other in the direction of movement of the roller shutter curtain, with at least one locking member, the upper sharp end of which can be pressed against one leg of the guide rail and on the one hand via a first link-shaped coupling member for transmitting the pressing force is connected to a lower bracket fastened to a lower profile bar and via a second coupling member to an upper bracket fastened to an upper section bar, the locking member and the coupling links being movable perpendicular to the plane of the roller shutter curtain.
  • the object of the invention is to provide a roller shutter safety device in which the locking member can be clamped and wedged directly within the guide rail without an articulated connection being arranged within this clamping path.
  • the invention differs from the prior art in that the locking member is pressed like a gag with both ends on opposite legs of the U-rail.
  • the locking element is pressed into the U-rail as a gag and wedged in it. So that can the entire clamping force can be absorbed within the locking member.
  • the length of the locking member is fixed. There are no fluctuations or changes due to a joint connection.
  • the coupling straps transmit the compressive forces that occur on the roller shutter curtain in the event of unauthorized manipulation and cause the gag-like locking element to be braced and wedged.
  • An increased securing effect is achieved in that several pairs of locking members arranged in a cross shape are provided one above the other.
  • a forced guidance of the locking members is ensured in that the locking members are connected to one another in the middle by a pivot pin.
  • the centering within the U-rail is ensured in that the locking members are each coupled to the lower bracket or bracket bracket by a coupling bracket.
  • a forced guidance of the locking members is ensured in that the two coupling straps are connected to the lower bracket or mounting bracket in a common hinge axis.
  • the orderly actuation of the locking members is improved in that the locking members are articulated on coupling lugs which are connected to the upper bracket via a joint joint and the tension band.
  • the engagement can be improved by connecting the upper coupling links to the joint via one or more mounting brackets.
  • a firm connection with the roller shutter curtain is achieved in that the upper bracket is aligned two parallel to each other Has legs between which a wall of a profile bar is accommodated.
  • the lower bracket which must be adjustable in height, receives a firm connection with the respective profile rod in that the lower bracket has claws on its leg.
  • the figures show a U-rail 1 with two legs 2 and 3.
  • three profile bars 4 are shown, which are hung one inside the other with hook profiles or profile webs.
  • a mutual displacement of the profiled bars is possible when the roller shutter is pulled up, compare FIG. 1.
  • the profiled bars according to FIG. 3 essentially sit one after the other. This means that the mutual vertical spacing of the profile bars 4 is smaller in the closed state of the roller shutter.
  • a bracket 6 is fastened to a lower profile bar, which is screwed, riveted or otherwise fixed to the lower profile bar 4 with a leg 7.
  • On the leg claws 25 are angled, which penetrate into the wall of the profile bar and thus ensure a firm connection.
  • the leg 7 can be adjusted in height to the respective installation conditions.
  • the bracket 6 includes an articulated mounting bracket 8, at the upper end of which 9 coupling links 10 are articulated on a pin 9.
  • the bracket tab 8 allows automatic adjustment and centering within the U-rail 1 regardless of the profile bars of the roller shutter curtain.
  • Each coupling plate 10 is connected to a locking member 11 via a hinge pin.
  • the two locking members are angular at the lower end 13.
  • One or more locking teeth 14 are provided at the upper end.
  • the two locking members 11 are crosswise coupled to one another via a hinge pin 15.
  • a spreading spring 21 biases the coupling plates 10 in the locked position. You can couple several pairs of locking elements together.
  • a coupling tab 16 is articulated.
  • the two Koppella 16's are connected to a drawstring 18 via a joint 17. It is also possible to arrange a tab 24, which is drawn in dash-dotted lines in FIG. 2, between the joint 17 and the tension band 18.
  • the tension band 18 can be a band, a wire, a chain, a link link pull or other tension element that can transmit a tensile force.
  • the tension band 18 is fastened to an upper bracket 19, the legs 20a and 20b of which are connected to an upper profile bar 4.
  • the legs 20a and 20b enclose the wall of the respective profile bar between them. Since the fastening elements such as screws or rivets hold in the thighs, a permanent and tear-resistant connection is guaranteed.
  • two tabs 22 and 23 can also be provided, which are shown in dash-dotted lines in FIG. 2. These tabs can also transmit a compressive force and thus ensure that the roller shutter safety device is in direct contact.
  • the roller shutter lock according to the invention is located within the U-rail 1 and lies against the central web thereof, as can be seen in particular from FIG. 2. Since all parts of the roller shutter safety device are plate-shaped, the roller shutter safety device has only a small extension in the longitudinal direction of the profile bars, so that it can be accommodated concealed within the U-rail without difficulty.
  • Fig. 1 shows the roller shutter curtain in the pulled-apart state within the profile rail.
  • the roller shutter lock is pulled apart because the brackets 6 and 19 are arranged accordingly on the profile bars, so that the individual members of the roller shutter lock elongate to each other.
  • the movement of the roller shutter armor when lifting or lowering the same is not hindered by the roller shutter safety device in this state.
  • each locking member 11 is gagged.
  • the joint axis defined by the pin 9 and the axis of the joint 17 center themselves within the U-rail in such a way that the locking members 11 bear evenly on the legs 2, 3 of the U-rail 1 with both ends.
  • the articulated connections favor a uniform spreading of the two locking members 11. This centering is favored by the mounting bracket 8 and the tension band 18, since this element moves in a transverse direction Allow direction of U-rail 1.
  • each locking member 11 engages with at least one locking tooth 14 on the leg 3 of the U-rail 1.
  • the lower end 13 is pressed against the opposite leg 2.
  • the locking member 11 is wedged like a gag within the U-rail.
  • the clamping force is transmitted by the locking member 11 itself to both legs of the U-rail. Since the locking member 11 is tab-shaped, a high clamping force can be achieved.
  • the crosswise arrangement of two locking members 11 ensures an inevitable movement and wedging of the locking teeth 14 when the lower profile bars 4 are pushed up.
  • a plurality of locking teeth ensure firm jamming in U-rails of different widths.
