Definitions

  • the invention relates to a device for opening and closing a flap pivotally mounted on one side of a frame of the type specified in the preamble of claim 1.
  • Such devices are main components of smoke and heat extraction systems and serve to close the flaps, e.g. Skylights or skylights integrated in skylights, which cannot be opened manually, can be opened and closed hydraulically, pneumatically or electromotively if necessary. Normally, this creates ventilation for the room in question; In the event of a fire, an automatically releasable smoke and heat vent can be provided with such a system.
  • the German utility model G 8 808 856 describes a smoke vent and ventilation flap with a device for opening and closing a roof flap. Another smoke and heat extraction device is known from utility model G 8 124 554, an opening angle of over 90 ° being achieved for one or more skylight domes.
  • the utility model G 8 006 402 has a device for opening and closing a smoke and heat flap to the subject.
  • a specially designed lifting cylinder is described in detail, which is particularly suitable for emergency opening of the flap.
  • the device according to the above-mentioned patent is in the assembled and closed state a very bulky unit and, because the three pivot elements are connected at a point that lies far below the surface formed by the underside of the frame, can only be transported individually. Since this type of transport is very complex and expensive, such systems are usually delivered to the destination, unassembled or partially assembled, where the final assembly then takes place. The disadvantages arising from this are high assembly costs at the destination, difficult assembly conditions at the destination, additional safety measures required during assembly and additional costs for packaging, storage and shipping of obstructive components. When the bulky complete system is delivered in single transport, there are high transport costs to the destination.
  • the object of the present invention is to provide a device for opening and closing a flap of the specified type, which makes it possible to stack several fume cupboards with already installed, functionally tested opening and closing devices for transport without having to make large installation efforts at the destination or the above-mentioned disadvantages regarding transport in the disassembled state occur.
  • Both the lifting cylinder and the swivel arm together with their fastening devices form one-piece units, so that no further individual parts are required for the final assembly. If the connection between the lifting cylinder and swivel arm is released, the opening and closing device already assembled with the flap can be folded into the space under the flap without further disassembly and held together with simple aids, such as cable ties, so that it is possible to complete several Stacking systems for transport on top of each other and delivering them completely and compactly to their destination. There, the transport lock can be easily released and the opening and closing device can be assembled in a few simple steps by connecting the two fastening devices.
  • the fixed but detachable connection of the two fastening devices of the lifting cylinder and the swivel arm can be made in different variants.
  • Some examples of this are a bayonet lock, a threaded lock, a locking disc lock, a snap lock and a slot lock.
  • the present invention has the following advantages over the prior art: At the place of final assembly of the smoke and heat exhaust system, screwing work is no longer necessary, since only the transport lock has to be released and the lifting cylinder has to be locked. Safety devices, such as nets against falling Parts can be omitted due to the use of mechanically secured components. An opening and closing device that has already been functionally tested at the factory no longer has to be dismantled for transport. The lines and connections for the supply of working fluids are not disconnected after the first installation. At the final assembly site, no individual parts can be missing and no construction-like parts of other devices can be confused with those belonging to the opening and closing device. The assembly personnel can work from a secured position during final assembly and do not have to operate over the open roof cutout of the room.
  • the lifting cylinder decoupled for transport can be used again without the use of tools.
  • An assembly hook-on scaffold is no longer necessary for oversized smoke and heat exhaust ventilators.
  • a single function test of the device assembled in the factory can be omitted after the final assembly on site because the important parts no longer have to be dismantled for transport.
  • the complete smoke and heat exhaust ventilation systems pre-assembled and secured for transport can be stacked in groups of several. The transport costs per unit can thus be reduced to a minimum.
  • Figure 1 shows the smoke and heat exhaust system in the closed state.
  • a roof opening Frame 2 attached.
  • a strut 9 is provided, on which a bracket 4 is attached.
  • a swivel arm 5 is articulated on the strut 9.
  • a damping element 8 is articulated at the lower end of the console 4.

  • the free end E5 of the swivel arm 5 is fixed, but articulated, to the end E1 of a lifting cylinder 1 by the fastening devices 6 and 7, shown in detail Y.
  • the other end of the lifting cylinder 1 is articulated on the side of a flap 3 opposite the articulation side of the frame 2.
  • Extending the lifting cylinder 1 causes a pivoting movement of the flap 3 around its articulation point on the frame 2 in a clockwise direction, which corresponds to an opening of the smoke and heat exhaust system.
  • the swivel arm 5 and a damping cylinder 8 have the purpose of balancing the mechanically generated forces at the connection point of the fastening devices 6 and 7 and of holding the opening and closing device in the desired opening position.
  • the smoke and heat exhaust system in its partially open position is shown in Fig. 3.
  • the lifting cylinder 1 is extended into its longest position and the flap 3 is opened to extract smoke and / or warm air from the interior of the room.
