Definitions

  • the invention relates to a locking device provided on a roller shutter of the type specified by claim 1.
  • a locking device of this type known from DE-GM 69 29 903 for so-called mini-roller shutters
  • the free end of the bow spring is riveted directly to the central hollow chamber of the top roller shutter rod, so that its free end edge formed by a hook strip in the event of an unauthorized pushing up of the Roller shutters can be pushed from the outside into a holding mouth which is open at the bottom and has an opening width of an L- or U-shaped profile bar which corresponds to the thickness of the top roller shutter bar, by means of which a sheet metal box covering the mini roller shutters is screwed to a window frame.
  • the fastening rivet for the free end of the bow spring thus forms the decisive pressure transmission element for its internal stress, under which the hook strip of the top roller shutter bar is threaded into the holding mouth of this profile bar, which forms a stop, if the roller shutter should be pushed up from the outside without authorization. If, on the other hand, the roller shutter is pulled up in an authorized manner by a rotation of the winding roller caused by a belt pulley with a winding belt, then the internal tension of the bow spring on its fastening rivet is translated for a deflection of the top roller shutter rod against the winding roller.
  • the invention characterized by the claims solves the problem of designing a locking device of the specified type provided on a roller shutter in such a way that when used on roller shutters of larger area and therefore also having a correspondingly greater weight, a greater security factor for an unauthorized pushing up of the roller shutter from the outside in cooperation the bow spring is obtained with the stop provided for the free end edge of the top roller shutter bar.
  • the advantages achieved by the invention are essentially that, by integrating the connecting rod, an effective pressure transmission member is obtained in the center of gravity of the uppermost roller shutter rod, on which the internal stresses of all the bow springs provided for its suspension are concentrated when the roller shutter is lowered. Because the connecting rod simultaneously forms an abutment under this internal stress of all the bow springs with respect to the stop, on the other hand the outer wall of the top roller shutter rod is pressed against the inside of the outer wall of the roller shutter box with this tension concentrated on the connecting rod, part of this compressive force then also experiences a transfer to the free end edge of the uppermost roller shutter bar which is in engagement with the stop. If, therefore, unauthorized attempts should be made to push up the lowered roller shutter from the outside, the abutment formed with the connecting rod proves to be so strong that the roller shutter cannot even be moved by a few centimeters.
  • the locking device according to the invention also provides an extremely simple and largely error-free installation option, regardless of how many bow springs are provided for a suspension of the roller shutter on the winding roller, which may be realized by means of additional belt straps, because the inner wall of the top roller shutter rod for exposing the connecting rod at its central hollow chamber can be easily cut out and it is not difficult to attach the associated bow spring to the part length of the connecting rod inserted into the central hollow chamber which is exposed by the cutout.
  • the roller shutter box shown in Figure 1 in its installed position under the supporting lintel of the wall opening of a window has a design according to DE-PS 32 23 880 and therefore consists of a U-shaped first box part 1 and an L-shaped second box part 2, the both made from wood wool bonded with mineral binder, especially cement (wood chips) exist.
  • the two box parts 1, 2 are glued together on the inner wall 3 of the roller shutter box forming a flange of the U-shaped box part 1 and on the short leg of the L-shaped box part 2 and with a curved heat-insulating lining 4 made of foam plastic, in particular foamed polyurethane, provided that is crescent-shaped so that the cavity of the roller shutter box has a curve that continues in a ceiling-side curve 5 of the U-shaped box part 1.
  • the longer leg of the L-shaped box part 2 forming the bottom of the roller shutter box has an arrangement above a window frame 6.
  • a profile strip 7 is fastened, which in cooperation with the outer wall 8 formed by the other flange of the U-shaped box part 1 constricts a passage slot 9, through which the upper ends of lateral guide rails 10 protrude into the cavity of the roller shutter box.
  • the roller shutter box has a winding roller 11 mounted in lateral bearings, to which the one end 12 of a bow spring 13 is fastened.
  • the bow spring 13 is provided together with other bow springs attached along the axis of the winding roller 11 at intervals of, for example, 50 cm and with a width of, for example, 2 cm made of spring steel for suspending a roller shutter 14, which is composed of interlocking hollow chamber profile bars is and is guided laterally by the guide rails 10.
  • the roller shutter 14 Upon rotation of the winding roller 11 is counterclockwise by means of a belt pulley attached to it (not shown) and a conventional roller shutter belt, the roller shutter 14 can thus be completely wound onto the winding roller 11 by means of the bow springs 13, whereby a winding indicated by the circular line 15 Knife for the roller shutter is obtained, with respect to which the ceiling-side curvature 5 of the roller shutter box also obtained with the inclusion of the lining 4 is essentially concentric.
  • the locking device comprises a rod 16 which is inserted into the central hollow chamber 17 of the uppermost roller shutter rod 18 loosely or alternatively with its center of gravity, or alternatively also snugly.
  • the with the roller shutter bar 18 having a substantially identical length 16 is exposed on the bow spring 13 by a cutout 19 of the inner wall 20 of the shutter bar 18, so that at this point the free end 21 of the bow spring 13 on the rod 16, for example, with training a tab can be attached, which is threaded over the cutout 19 for looping around the part length of the rod 16 exposed by it and fastening its free end by spot welding 22.
  • the connecting rod 16 which is therefore provided jointly for all the bow springs, is made of metal, then alternatively a direct welding of the bow springs can also be provided with a suitable precaution against a risk of damage to the roller shutter bar, which on the other hand is therefore less critical with this preferred spot welding of a tongue formation of the bow springs .
  • the locking device further comprises a stop, which is formed by a stop shoulder 23 provided on the inside of its outer wall 8 or provided in the transition to the round curvature 5 of the roller shutter box, or an alternatively attached stop bar at the same point.
  • a stop shoulder 23 is completely down Let the roller shutter 14 hold the free end edge of the uppermost roller shutter slat 18 formed by a hook bar 24 by pressing its outer wall 26, which is provided with a sealing bar 25, by means of the connecting bar 16 through the internal tension of the clip springs 13 against the inside of the outer wall 8 of the roller shutter box .
  • the winding roller 11 is rotated counterclockwise for an authorized pulling up of the roller shutter 14, then the engagement position of the hook strip 24 with the stop shoulder 23 is thereby brought about by the connection rod 16, which counteracts the inherent tension of the bow springs 18, by tightening the uppermost roller shutter rod 18 against the winding roller 11 canceled so that the locking device is then no longer effective.
  • the stop shoulder 23 can already be provided during the manufacture of the roller shutter box by appropriately designing a press mold used for the U-shaped box part 1. Alternatively, it is also possible instead to design this stop shoulder 23 with the lining 4 in addition to a stop strip in accordance with the advice already given, which then only has to be continued accordingly.
