Definitions

  • the mounting plate carries the safety lever, which is designed as a one-armed lever and is mounted at its lower end in the assembled state.
  • the mounting plate is arranged with its level parallel to the roller shutter roller and thus parallel to the level of the roller shutter, it can coincide with or be placed on a corresponding wall of the roller shutter box.
  • the mounting plate also carries a load spring for the safety lever and other guides for the operating belt in the form of belt rollers. This is complex and cannot be easily assembled. In particular, it is not possible to design the described components of the device into a set of components which can be easily retrofitted to practically all conventional roller shutters for the purpose of realizing an additional burglar protection.
  • a roller blind is also already known (US-A-1 470 782), in which a mounting plate has a bearing for an axle stub of the roller shutter roller, the securing lever is designed as a two-armed lever, one of which lever arm is a guide for an actuating cord and the other of which is a lever arm bends with a rubber brake pad, and the safety lever is mounted next to and above the drum disc on the mounting plate and covers the drum disc. All of these measures, however, do not yet readily permit subsequent installation of the safety device mentioned at the beginning in the case of differently dimensioned roller shutters.
  • the object of the invention is to simplify the generic device and to further develop it in such a way that it can be installed in all conventional roller shutters without difficulty and that its components can be combined to form a corresponding set of components.
  • the mounting plate has a bearing for the stub shaft of the roller cap and is placed on it, and at the same time is designed as a bearing plate for the roller shutter roller and is to be fastened to an end wall perpendicular to the roller shutter axis in the roller shutter box, that the securing lever is a two-armed one Lever is designed, which has a lever arm which carries the guide for the actuating belt, and has a further lever arm from which the pawl is angled, that the mounting plate has a plurality of holes distributed according to a grid for the storage of the safety lever, and that the safety lever in the assembled state next to, ie is mounted parallel and above the drum disk provided with locking elements on the mounting plate and covers this drum disk with the pawl.
  • the invention makes use of the fact that the roller shutters currently in use are equipped in the manner described with roller caps, which are largely standardized, and that the stub axles of the roller caps must be stored in the roller shutter box anyway.
  • the mounting plate present in the generic locking device fulfills a double function in the device according to the invention, because it serves both as a bearing for the stub axle and for mounting the locking lever.
  • the bearing for the stub axle can be a ball bearing.
  • the mounting plate and the safety lever are supplemented as a set of components by the belt drum, of which at least one drum disc is equipped with locking elements in the manner described.
  • the locking elements can be teeth or corresponding recesses.
  • the locking elements can be passed over by the pawl in this direction of movement of the belt drum or can be moved under the pawl while the blocking takes place in the other direction of movement of the belt drum.
  • the securing device can be used with all conventional roller shutters without difficulty and can also be placed on the market as a set of components, it is provided that the mounting plate has a plurality of bores for mounting the securing lever. Nurso can be adapted to different shutter geometry.
  • the mounting plate preferably has a plurality: of holes for fastening screws distributed according to a grid for fastening in the roller shutter box.
  • the recommendation that the securing lever has a plurality of spaced-apart holes for the Includes a bearing pin so that lever arms of different lengths can be set up. This is particularly advantageous for a preferred embodiment of the invention in which the actuation of the locking lever into the locking position takes place under the influence of gravity. But it can also be used with a corresponding load spring, which can also be attached to the mounting plate.
  • the embodiment in which the securing lever engages with its pawl in the locking elements by the action of gravity is characterized in that the lever arm carrying the pawl, e.g. B. by dimensioning its length, is heavier than the lever arm carrying the guide for the actuating belt.
  • the advantages achieved can be seen in the simplicity of the device according to the invention, which allows the device to be installed in all customary roller shutters. For this purpose, the device can be brought onto the market as a set of components.
  • the belt drum 3 can be placed on the roller cap 7, for which reference is made in particular to FIG. 4. 3 shows the attached state.
  • one of the drum disks 4 is provided with locking elements 10, which are distributed over its circumference and are designed as locking teeth 10.
  • the safety lever 5 has a guide 11 for the operating belt 1. By exerting a tensile force on the operating belt 1, the safety lever 5 can be pivoted into the position shown in FIG. 2.
  • the locking teeth 10 can be passed over by the locking edge 6 in the direction of the arrow 12 shown in FIG. 1, the roller shutter 2 can thus be lowered.
  • the locking elements 10 have a locking effect when the pawl 6 surrounds.
  • Fig. 2 shows the position in which the roller shutter 2 can be pulled up via the actuating belt 1 and consequently the pawl 6 has been disengaged. It goes without saying that the roller shutter 2 is wound onto the roller shutter roller 14, which was indicated in FIG. 3.
  • the mounting plate 9 has a bearing 15 for the stub axle 8 of the roller edge 7, is placed thereon and at the same time is designed as a bearing plate for the roller shutter roller 14 and is to be attached to the end in a roller shutter box , the box wall in Fig. 3 may follow on the left. It would be located in the drawing plane in FIGS. 1 and 2. 1 and 2 in particular that the securing lever 5 is designed as a two-armed lever, which has a lever arm 5a, which carries the guide 11 for the actuating belt 1, and has a further lever arm 5b, from which the pawl 6 is angled is (Fig. 3).
  • the mounting plate 9 has a plurality of holes 16 distributed according to a grid dimension for fastening screws for fastening in the roller shutter box.
  • the mounting plate 9 also has a plurality of bores 17 distributed according to a grid dimension for the mounting of the safety lever 5.
  • the securing lever 5 in turn has a plurality of bores 18 arranged at a distance A from one another for receiving a bearing pin 19. If the bearing pin 19 is inserted into different bores 18 and screwed accordingly into bores 17 of the mounting plate 9, 5 lever arms 5a can be attached to the securing lever 5 , 5b of different lengths.
  • the securing lever 5 can be locked into the locking elements 10 by gravity with its pawl 6.
  • the arrangement is such that the lever arm 5a carrying the pawl 8 is heavier, that is to say longer in the exemplary embodiment, than the lever arm 5a carrying the guide 11 of the actuating belt 1.
  • 4 shows the set of components from which the safety device according to the invention consists. 1 and 2 also show that the mounting plate in the exemplary embodiment below the bores 18 for receiving the bearing pin 19 has a series of bores 20 for a stop 21 which limits the pivoting movement of the securing lever 5 when the securing lever pivots by 19.
