Definitions

  • the invention relates to an automatically closing opening closure according to the preamble of patent claim 1.
  • Such an opening closure (for a fan) is known from DE 24 14 164 A1. This serves to close an opening as required and uses to save space of several slats instead of a large flap to cover the area to be closed in terms of area.
  • the invention has for its object to provide such an opening closure such that it can also be used at openings that must be closed in case of fire for safety reasons in any case, and automatically and fire resistant.
  • the closure for example, having a flap or a plate element, is designed to be smoke-tight in the closed position, wherein an opening force counteracting the restoring force can be generated by means of an actuating element electrically connected to a smoke detector, and in that at least one fire-retardant, preferably fire-resistant, and at least one flow channel having body is arranged, which optionally provided in the region of the flow channel with a intumescent intumescent under heat or even formed of intumescent material.
  • Such an opening closure will regularly be arranged in the region of a ventilation opening and in the open position connect two spaces with one another.
  • the air of the one space thus flows through the shutter held in the opening position (for example lamellas) and through the flow channel of the provided with an intumescent or formed from it, fire-retardant designed body in the other room, or vice versa.
  • the slats are held in the open position by means of an actuating element, preferably a simple electromagnet. Without this opening force, for example, return springs provided on the slats would lead to closure of the slats.
  • the actuator or the solenoid is in turn electrically connected to a smoke detector. Detects this one case of fire, ie smoke, the further power supply to the electromagnet is prevented, resulting in an almost sudden, but (at least still) reversible closure of the slats.
  • the flap closure in the opening is assigned a fire-retardant body whose at least one flow channel also provided with an intumescent material or itself is formed from intumescent material. If the opening closure is thus acted upon by one of the two rooms not only with cold smoke but also with heat (eg air or smoke with a temperature above 50 ° C.), this leads to a foaming of the intumescent material (preferably expandable graphite) and thus to an irreversible fire-resistant closure of the opening.
  • the intumescent material preferably expandable graphite
  • FIGS. 1 to 3 a preferred embodiment of the automatically closing opening closure according to the invention is shown in three views. This comprises in particular a closure 2 closing an opening 1, which can be brought into the open position against a permanently acting restoring force.
  • the lamella closure consists of several (here four), against the aforementioned restoring force to be opened single lamellae 8, which are pivotable about horizontally extending axes of rotation 10, wherein on the axes of rotation 10 spring elements (not shown) for the self-closing of the individual lamellae 8 are arranged.
  • the closure 2 is formed smoke-tight in the closed position, wherein one of the restoring force counteracting opening force can be generated by means of a smoke detector 3 electrically connected control element 4, and that in the opening 1 an at least fire-retardant (here fireproof) and at least one flow channel 5 (here four) having body 6 is arranged, which optionally provided in the region of the flow channel 5 with a intumescent intumescent material 7 under heat or (see Figure 17) itself is formed from a potting compound of intumescent material 7.
  • seals 9 are provided on the individual lamellae, which ensure in the closed position that no gas, in particular no smoke, can pass through the opening closure.
  • the fire-resistant body 6 is formed in the embodiment according to Figures 1 to 3 of a mineral building material, such as gypsum.
  • the intumescent material 7 consists of expandable graphite. This expands under the action of heat very strong and closes the flow channels 5 such that the opening 1 in any case for a certain time (depending on the desired legal standard) is considered to be fire-resistant sealed.
  • the expanded graphite can, as shown, for example, be arranged as a layer on the edge of the tubular flow channels 5. Of course, however, any other arrangement comes into consideration, which leads to a fire-resistant completion of the flow channels 5.
  • the connecting element may, as shown, be designed as a cable 11, which is connected on the one hand to the adjusting element 4 and on the other hand in each case with a projecting beyond the axis of rotation 10 lever arm on each individual lamellae 8.
  • the adjusting element 4 is also preferably designed as an electromagnet, wherein this has a movable armature 12 operatively connected to the closure 2.
  • the previously mentioned cable pull 11 is operatively connected to the armature 12 of the electromagnet in order to actuate the lamella closure. If there is no current at the electromagnet (due to power failure or due to a fire), the lamellar shutter closes automatically.
  • the adjusting element 4 is formed as a pneumatic cylinder 13.
  • the slide is connected to a compressed air valve.
  • a spring 14 is mounted, this pushes the slider down and closes the flap. If the pressure valve is supplied with sufficient compressed air, this pushes the slider against the spring force upwards and the flap is opened. If a fire or smoke is detected, then additional valve opens and the compressed air is released, by the spring force, the flap is then closed again.
  • the adjusting element 4 is formed of an electric 15 and a permanent magnet 16.
  • a permanent magnet is attached to the lower end of the slider, which opens or closes the door.
  • an electromagnet is mounted below this permanent magnet. If this is supplied with electrical energy, this builds up a magnetic field. The magnetic field is such that the magnetic field of the permanent magnet is repelled therefrom; This pushes the slider up and opens the door.
  • the magnetic field also collapses and the slider is pulled down by the weight of the permanent magnet and the attractive force that the permanent magnet exerts on the iron core of the electromagnet. the flap is closed again.
  • the adjusting element 4 is formed from an electrically operated rotary magnet 17.
  • a rotary magnet is attached to the lower end of the slider on which the individual flap elements are mounted.
  • a spring 14 is mounted at the upper end.
  • the spring 14 presses the flapper permanently down in the direction of the rotary magnet 17.
  • the flap is closed by the individual elements. If the magnet is now activated, it rotates about its own axis and pushes the slider upwards against the spring force with the aid of its attachment; the flap is opened thereby. If the power supply to the rotary solenoid, for example, is interrupted by a smoke detector, this rotates back to its original position. About the spring force, the flap is closed again.
  • the adjusting element 4 is formed from a bi-metal 18 and a heating element 19.
  • a bi-metal 18 is used below the flap elements; this is connected to the slider for the flaps. Without energizing the flap is now closed. If the bi-metal 18 is heated, this changes its shape and pushes the slider upwards; the flap is opened until the bi-metal 18 has reached its maximum state of deformation. The flap is now completely open. If the heat supply to the bi-metal 18 is interrupted, e.g. because the power supply to the heating element 19 is interrupted by a smoke detector, the bi-metal deforms to its original shape and the flap is closed again.
  • the adjusting element 4 is formed by an electric motor 20 with a toothed drive 21.
  • a small electric motor 20 is mounted in the lower region of the flap, on whose shaft a gear is mounted.
  • the motor is fixed so that the gear and the teeth in the slide mesh.
  • the motor is supplied with electrical energy, it moves the slider upwards via the gear, the flap is opened.
  • a limit switch is used to determine whether the flap is fully open; the engine then stops in this position.
  • smoke or fire detection of the motor 20 is driven so that it rotates the gear in the other direction and the slide is so again transported down until a smoke detector reports the closed state of the flap.
  • the adjusting element 4 is formed of an electromagnet 22 and a metal retaining plate 23.
  • a piece of metal holding plate
  • an electromagnet 22 Above the metal piece is an electromagnet 22. Is this with supplied electrical energy, it attracts the metal piece 23 and thus also pulls the slider upwards. The flap is opened by this. If the power supply is interrupted in succession by detecting smoke or a fire, the magnetic field degrades and the flap moves downwards by the weight of the piece of metal. The slider also moves down and the flap is closed again.
  • the adjusting element 4 is designed as a fan 24.
  • the closure 2 is positioned on one side and the fan 24 on the other side of a wall opening.
  • the fan 24 is turned on. Detects the smoke detector 3 a fire, the power supply to the fan 24 is interrupted, so that the slats go by itself in the closed position.
  • the air flow generated by the blower 24 thus serves in this embodiment to keep the closure 2 open.
  • the closure 2 is designed as an axially displaceable plate element 25.
  • the plate element 25 is preferably slightly larger in diameter than the opening 1 itself. It is actuated by means of a bearing axis, which represents the extension of the armature 12.
  • the plate element 25 is arranged on one side and the adjusting element 4 (here an electromagnet with armature 12) of a wall opening. So that it automatically closes in case of fire, it is provided that the armature 12 is operatively connected to a spring 26 which produces a permanently acting restoring force.
