Definitions

  • the invention relates to a closing device for closing openings in shelters according to the preamble of the main claim.
  • a fireproof steel cabinet, safe or the like in which a double wall is provided, which is filled with a chemical solid with a melting point of about 30 to 40 ° C. With increased temperature influences due to a fire or the like in the vicinity of the steel cabinet, the thermal energy acting on the cabinet is used over a longer period of time to overcome the melting point of the chemical solid.
  • This cabinet has two doors, each of which can be actuated from the outside, the inner door being double-walled and filled with the chemical solid.
  • the outer door has two chambers, on the one hand glass wool and on the other hand concrete.
  • the door stops are located on the outside of the wall. The entire load of the doors is thus held by the wall.
  • the invention has for its object to provide a closing device for closing openings in shelters, which maintains the tightness for shielding the interior against external influences even at high temperatures and mechanical loads from the outside and which both from the inside as well as opening and closing from the outside.
  • the locking of the wall element is arranged on its inside, the actuating device actuating the locking being accessible both from the inside and from the outside.
  • the lock can thus be arranged in the cold area. Due to the design according to the invention, a double door is therefore not necessary, so that handling is much easier.
  • the support arm is rotatably supported not only on a spar of the support structure, but also on a connecting piece connected to the door, so that several degrees of freedom are available for pivoting out the wall element.
  • a control lever is additionally provided, which is also pivoted on the spar and on the connecting piece.
  • the articulation points of the control lever and the support arm are arranged on the spar and on the connecting piece in such a way that the swivel paths of the articulation points on the connecting piece intersect around the articulation points on the spar.
  • the safe fire protection separation of the actuation device is realized by that it has a shaft passing through the wall of the wall element, which is interrupted within the wall to form two partial waves, which are connected by a connecting element that dissolves in the event of a fire.
  • the lock can thus be actuated via a shaft which is continuous in the normal operating state and which is interrupted when exposed to heat, so that no heat conduction can take place.
  • a material that can be foamed at high temperatures is advantageously provided around the actuating device.
  • the foamable material is selected such that it releases water vapor when foaming, which is also used to cool the partial waves. If the material is located in the outward-facing area, it becomes effective particularly during the first to second hour of the fire. If the material is provided between the partial waves, cooling takes effect between two and twenty-four hours after the start of the fire.
  • the actuating device advantageously has an electromagnet with a magnetic plate, via which the locking bolts of the locking device are held in the retracted state after their complete unlocking.
  • the locking bolts do not interfere with the movement of the door, ie they do not rub against the door panel, so that the amorphous fire protection material is not damaged.
  • the wall element is provided with a drive unit, preferably arranged in the cold area and having an electric motor, which automatically opens or closes the wall element after unlocking the locking bolts.
  • a drive unit preferably arranged in the cold area and having an electric motor, which automatically opens or closes the wall element after unlocking the locking bolts.
  • the drive unit has two interconnected levers, one of which is attached to the wall element and the other of which is operatively connected to the electric motor of the drive unit, such that the angle between the levers approaches zero when the wall element moves in the closed state.
  • the motor has the greatest force when the wall element is in an approximately closed state due to the sinusoidal movement and thereby pulls the wall element correctly into the reveal, at the same time the metal plate is released from the electromagnet and the locking bolts move out.
  • the drive unit has a pinion driven by the electric motor and a toothed disk which is seated on a shaft and engages with the pinion, the movement of the Wave causes the movement of the wall element.
  • the pinion for releasing the engagement with the toothed disk is arranged displaceably, the displacement being able to be carried out via a linkage.
  • a slipping clutch is provided so that no people are trapped by the drive unit when the door closes automatically.
  • the actuation of the actuating device for opening or closing the locking is usually carried out via two handwheels, which are each arranged at the ends of the shaft of the actuating device. If the wall element is only to be opened by authorized persons, an electric motor can be provided instead of the handwheels, which rotates the shaft of the actuating device, the electric motor being able to be controlled, for example, by a coding device.
  • Fig. 1 the section through a shelter 1 is shown, which is usually arranged in a building on a concrete floor 2.

  • Control levers 20 are arranged adjacent to the support arms 18 and are likewise articulated at one end to the spar 16 and at the other ends to the connecting piece 19.
  • the control levers 20 When moving out the wall element, the control levers 20 prevent pivoting of the wall element 5 at the beginning of the movement and ensure a movement of the wall element 5 parallel to the opening 4 until the pivoting movement is released, which is not possible at the beginning because of the thickness of the wall element and the wall.
  • the support arms 18 In the open state of the wall element, the support arms 18 are approximately perpendicular to the opening, ie they are at an angle of approximately 90 °, if an imaginary line from the respective articulation points 21, 22 on the bar 16 parallel to the width of the passage 8, the angle of 0 ° defined. In this position of the support arms 18, the angle between the imaginary line and the control levers 20 is greater than 90 °.

  • the control levers 20 are preferably longer than the support arms 18.
  • the opening 4 in the wall 9 is wider than the passage 8, so that a small opening area 25 remains next to the spar 16, which to the outside as well as the support arms and the control levers in the closed state of the wall element 5 thereof is covered.
  • This open area 25 is preferably covered from the inside with a covering or the like.
  • the closing device is described in the exemplary embodiment for closing accessible passages. In the same way, however, closing devices for air-conditioning openings or the like can be designed.

  • the sleeve 121 transmits the rotation of the partial shaft 118 to the partial shaft 119 and vice versa.
  • a tubular grid or perforated plate 123 is arranged, which is surrounded by a second, larger diameter grid 124, so that a space is formed between the perforated plates, which with a foamable material 125 is filled.
  • the foamable material consists for example of calcium silicate or sodium silicate mixed with water glass.
