Definitions

  • the invention relates to a roller shutter with a lattice-shaped curtain, in particular metallic, burglar-resistant, curtain armor consisting of articulated interconnected lattice members, with a security device which has at least for the opening movement of the lattice effective light barrier monitoring device on both sides of the lattice, which is preferably in the upper half of the is arranged with the grating to be closed building opening and the light rays are approximately perpendicular to the direction of movement of the grating.
  • Roller grilles of the type in question are wound up and unwound, like roller shutter curtains, on a roller arranged behind the lintel area of the opening to be closed.
  • a safety device in the form of a conventional closing edge safety device to prevent people standing underneath from getting caught.
  • a special feature of a roller shutter in the form of articulated lattice elements is that, in contrast to a roller shutter armor that is closed to this extent, it is possible to reach into the lattice mesh or enter with the foot. This is like from the outside possible from the inside. If the grille moves upwards or then into the open position, there are very considerable dangers.
  • the invention has for its object to make the security device for reporting people or objects carried by the opening grille cheaper and easier to assemble.
  • this is achieved according to the invention in that one and the same scanning beam from a light transmitter, in particular in the infrared region, runs back in a first section along one broad side of the grille in the gate opening region and in a second section along the other broad side of the grille is guided to the light receiver in that a reflector is arranged in the edge region of the building opening located to the side of the lattice, opposite to the other edge region in which the light transmitter and the light receiver are arranged, a reflector which the light beam emitted by the light transmitter by 180 ° and deflected laterally offset in the thickness direction of the grating and feeds the light receiver.
  • each with one light transmitter and one According to the invention light receivers, thus to be wired in both edge regions of the building opening to be closed, will only use one light transmitter and one light receiver to which a reflector is assigned.
  • the light transmitter and the light receiver are located in the same edge area, so that only wiring (cable routing) is required in this area, while the reflector arranged in the opposite edge area does not require any electrical connection.
  • the reflector preferably consists of two flat mirror surfaces which are arranged at right angles to one another such that each of the two mirrors is assigned to one of the two broad sides of the grating at an acute angle.
  • the light beam emanating from the light transmitter is first deflected by the first mirror from the latter to the second and from there reaches the light receiver; the beam behaves according to the optical laws of reflection according to the angle of incidence and angle of reflection.
  • both mirrors do not have to be at an angle of 45 ° to the grating plane, for example, it can also be 60 ° at one angle and 30 ° at the other.
  • the beam path will preferably run perpendicular to the direction of movement of the grating, but this is not mandatory.
  • a roller is preferably assigned to the grid, which shifts on its supports during winding and unwinding of the grid in such a way that the rising and falling grid is always moved in practically the same plane towards the door opening when the bale thickness changes on the roller. This prevents bulging of the lattice curtain, as can occur if the roller always maintains a rigid distance from the lintel of the building opening regardless of the winding condition of the lattice.
  • the beam guidance can thus take place closer to the reliable grating remaining on one level, whereby the space requirement of the light barrier device perpendicular to the grating plane is less.
  • the guides for the side edges of the grating arranged on the side of the building opening run over corresponding guide holders at a certain distance from the inner edge of the building opening, which makes it possible, in a particularly preferred embodiment, for the front to guide the grating-monitoring beam between the guide rail and the associated edge region of the gate opening.
  • the drive 7 of the winding roller is slidably controlled in such a way that the roll of the bale 4 rolls off Curtain section is aligned with the guide direction of the guide rails 5 and 6; such an approximately perpendicular to the wall having the door opening to be closed, more precisely its lintel area above the door opening, is known from the prior art and is not further explained here.
  • the safety device comprises a light transmitter 8 and a light receiver 9 as well as a reflector 10. Basically, these can be transmitted, reflected and received beams of different physical types, in particular different frequencies, preferably in the infrared range.
  • the special feature of this safety device is the use of a reflector and thus the possibility of detecting objects on both sides of the lattice curtain with one and the same beam emitted by the light transmitter and received by the light receiver or its uninterrupted course. An upper area of the door opening is preferably monitored.
  • the particular advantage of using a radiation reflector is not only that only one light transmitter and one receiver is required for monitoring the grille curtain on both sides of the broadside, but that the supply for generating the beam in the transmitter and monitoring the reception of the beam and thus the subsequent control 11 is limited to only one side area of the latticed tank or the gate opening.
  • the transmitter and the receiver in different horizontal planes and achieve an adapted beam guidance by aligning the reflector.
  • this would only make sense if, for some reason, the reporting threshold, ie the course of the emitted and monitored light beam, would like to run in correspondingly different angular directions and / or planes. Therefore, it is of course also possible not only to redirect the light beam hitting a horizontal plane, for example, by 180 ° around the other side edge of the lattice curtain, one could also use additional reflector measures first reflect the incoming light beam into another horizontal plane and only deflect it there in the sense of a shift in the response threshold on the inside and outside of the curtain.
  • the exemplary embodiment shows typical U-shaped guide rails, one 5 of which houses the light transmitter 8 and the light receiver 9 on both sides and the other of which has a deflection device (reflector 10) which guides the monitoring beam around the outside of this other guide rail 6 and is arranged behind it as far as this.
  • the preferred embodiment according to the exemplary embodiment provides an arrangement of light transmitter, light receiver and reflector approximately in a horizontal plane.
