Definitions

  • the present invention relates to a roller shutter with automatic locking in closing position.
  • Roller shutters are known used for closing windows or other different room openings.
  • Particularly roller shutters are known formed by strips of alluminium, wood or plastic and which are placed in succession with articulated connection so that they can be wound about revolving axles placed on the top of the room opening.
  • Such revolving axles are operated usually by electric motors, little winches or belts which allow the axle rotation and consequently the unwinding or the winding of the roller shutter that is sliding vertically.
  • the roller shutter is lowered so that its inferior side is at contact with the ground.
  • an undesirable operator can force the roller shutter from the outside and thrusting up the roller shutter he can get in the room.
  • more or less complex or efficient locking devices of the roller shutter are provided.
  • a roller shutter comprising a roller gate, a revolving axle to which said roller gate is connected by chain connection means which allow the winding of said roller gate about said revolving axle, and means to control the rotation of said revolving axle, characterized in that said chain connection means are formed by segments which are hingedly connected to rotate with respect to each other of very little angles and braking means for said revolving axle are provided which co-operate with said chain connection means in order to prevent a lifting of said roller gate by forces acting from the bottom.
  • the present invention it is possible to form a roller shutter that is automatically locked in closing position, so that anybody cannot lifts the roller gate from the outside and get in the room.
  • roller shutter comprising a roller gate 1 formed by alluminium strips 2 which are hingedly connected and can slide in the guides 3.
  • roller gate is connected to an octagonal section revolving axle 4 by two connection devices 5 formed by two chains 6 fixed at the bottom to the roller gate 1 and at the top to respective couples of octagonal rings 7 which are integral with the revolving axle 4, in turn hinged at 8 to the walls of the room opening which are not shown in figure 1.
  • the chain 6 of the connection device 5 comprises a terminal segment 9 connected to the first strip 2 of the roller gate 1 by the hooking of its curve portion 10, which forms a internal cavity 11, with a hook portion 12 of the strip 2.
  • the terminal segment 9 is connected to a adjacent segment 13 of the chain, which is more narrow than the segment 9, by a hook portion 14 of an extension 15 of the superior side of the segment 9, which is inserted in a circular cavity 16 of the inferior side of the segment 13 so that it can rotate only of a little angle with respect to the segment 9.
  • the segment 13 is the first one of a series of equal segments which are connected with each other by hook portions 14 as that before described.
  • the last and the next to last superior segment 13 of the chain 6 are fixed to the couple of octagonal rings 7 by a bolt 22 which engages in a cavity 23 of the extension 15 of the next to last segment, engaged in the hook portion 14 with the last segment, and in a cavity 14 of a portion 25 of a side of said octagonal rings 7.
  • the portion 25 shows others cavities 26 and 27 in correspondence of the cavities 19 and 23 of the last segment 13 of the chain 6, in which suitable bolts can engage in order to allow a more efficient connection of the couple of rings 7 to the chain 6.
  • Each of the octagonal rings 7 shows a portion 70 where a transversal hole is provided in which a bolt 28 engages in order to fix the position of the rings 7 in the revolving axle 4.
  • the roller shutter 1 With the wound chain 6 as described in figures 3 and 5, the roller shutter 1 is wound about the axle 4, as shown in figure 5. Then the operation of a electric motor 40 accommodated inside the axle 4 and having a braking device 41, the axle 4 can be made rotate counterclockwise (showing figure 5) and the roller shutter and the chain 6 are unwound so that the inferior last strip 2 of the roller gate 1 is at contact with ground. At this point a suitable automatism, which is not shown in figures, allows the braking and the stop of the electric motor 40 which so does not allow rotating to the axle 4. If an operator exercises a thrust from the bottom to the top on the roller gate 1, the blocking device intervenes formed by the connection device 5 and the braking device 41 of the electric motor 40.
  • the hook of the first strip 2 inside of the cavity 11 of the first segment 9 exercises a thrust to the top on the same segment and on the remaining part of the chain 6, and this, joining with the immobility of the revolving axle 4, allows a major curving of the same chain.
  • the extension 15 can rotate inside the circular cavities 16 only of a little angle, so that the roller gate can be lifted only in minimum part insufficient for the entry of a person from the outside of the room.
  • the blocking of the roller gate 1 does not prevent its successive rewinding by rotation of the revolving axle 4, which is controlled by the electric motor by means of a suitable pulse from the designated operator.
