  • the housing has a lower housing section, approximately trough-shaped in vertical section perpendicular to the axis of rotation of the rotary flap, surrounding the roof frame at a greater distance, above which there is a further, upper housing section which projects somewhat laterally from the roof frame.
  • a plurality of rotary flaps are arranged in a lateral passage opening within the lower housing section, which, in a substantially horizontal position, enable ventilation that is resistant to precipitation (so-called bad weather ventilation).
  • the entire passage cross-section of the upper housing section is filled with a horizontal blind.
  • the slats of this blind are completely closed when the rotary flaps are in the lower section of the housing for rainproof ventilation.
  • the slats of the Venetian blind located in the upper section of the housing can be opened completely (smoke and heat ventilation and so-called good weather ventilation).
  • the present invention has for its object to provide an effective combined smoke and heat exhaust and ventilation device, which is further simplified in structure and mode of operation.
  • the pivot axis of the single rotary flap is arranged within the vertical projection of the roof opening, in particular in the middle and above it, and the housing has a single outlet and is designed such that the rotary flap opens the outlet of the housing to the maximum in a first swivel position (smoke and heat extraction as well as so-called good weather ventilation), closes the outlet in a second swivel position together with sealing edges located within the housing and one in a third swivel position located between the first and the second Precipitation-proof ventilation through the outlet (so-called bad weather ventilation).
  • the device according to the invention is particularly simple. It comprises practically only a single flap, which must be arranged within a simple housing and pivoted into three specific positions in order to adjust or finally to close the device for smoke and heat extraction as well as good weather ventilation or on the other hand for rainproof bad weather ventilation.
  • the great simplicity of the device according to the invention results not only in a low outlay in the design and manufacture of the device combined with correspondingly low costs, but also in a high level of functional reliability and long service life of the device.
  • the outlet of the housing is advantageously located on the upper side thereof, and the rotary flap is arranged essentially vertically in the first pivot position, essentially obliquely in the second pivot position and essentially horizontally in the third pivot position.

  • the housing has two opposing, in particular symmetrical, lateral bulges, each of which extends in the vertical direction from above to below the pivot axis of the rotary flap and in the horizontal direction along the outer peripheral edges of the rotary flap in the third pivot position, preferably over the entire length the marginal edges, extending, when the rotary flap is arranged in the third pivoting position, the outer marginal edges of which each dip into a bulge in such a way that a passageway which is resistant to precipitation is formed in each case.
  • a particularly simple design of the housing is obtained if it has a cubic or cuboid basic structure, the base of which essentially corresponds to the surface of the roof opening corresponds.
  • the lateral bulges arranged outside the basic structure of the housing each have a substantially trapezoidal cross section in a vertical section perpendicular to the pivot axis of the rotary flap with sides tapering outwards.
  • the bulges are preferably funnel-shaped in their bottom surface in a vertical section perpendicular to the swivel axis of the rotary flap and each have a water drain, through which precipitation entering the housing when the rotary flap is arranged in the second or third swivel position can be discharged onto the building roof.
  • the connecting flange in the presence of a connecting flange arranged on the roof edge and a housing flange adjacent to it, the connecting flange has on its inside a circumferential extension which, together with the adjacent region of the housing surrounding it at a distance, has a circumferential channel for the inside of the housing including the rotary flap Forms (condensation) water, for the discharge of which onto the building roof, at least one passage opening is arranged between the connecting flange and the housing flange.
  • the housing expediently consists of a material corresponding to the respective application, in particular sheet metal, insulated sheet metal or the like.
  • the rotary flap can also consist of a material corresponding to the respective application, in particular of transparent plastic, such as polycarbonate, of sheet metal, of insulated sheet metal, of a sandwich plate or the like.
  • the rotary flap can advantageously be actuated in accordance with the respective application, in particular by means of a pneumatic, by means of an electrical, by means of a C0 2 actuating device or the like.
  • the combined smoke and heat extraction and ventilation device 1 according to the invention shown in the drawing is arranged on a building roof 2 with a roof frame 4 delimiting a roof opening 3.
  • Fig. 1 is only illustrated for the sake of completeness that, for example, an uninsulated roof structure (right half of the drawing) or an insulated roof structure (left half of the drawing) may be present.
  • the device according to the invention has a housing 5 which is supported on the roof frame 4 by means of a flange connection 13/14, which will be explained in detail later.
  • the pivot axis 7 of the rotary flap 8 is arranged within the vertical projection of the roof opening 3, in particular in the middle and above it.
  • the housing 5 has an inlet 9 and a single outlet 10 and is otherwise designed such that only the rotary flap 8 in a first swivel position I releases the outlet 10 of the housing to the maximum (smoke and heat ventilation and fair weather ventilation), in a second swivel position 11 together with sealing edges 11 a, 11 b located within the housing 5 closes the outlet 10 and, in a third III pivoting position located between the first I and the second 11, causes precipitation-proof ventilation through the outlet 10 (bad weather ventilation). This is explained in more detail below.
  • the outlet 10 of the housing 5 is located on the upper side thereof, and the rotary flap 8 is arranged essentially vertically in the first pivot position I, essentially obliquely in the second pivot position II and essentially horizontally in the third pivot position III.
  • the rotary flap 8 rests with its two outer edge edges on the sealing edges 11 a, 11 b projecting in their swivel path, the edge edge of the rotary flap 8 assigned to the higher sealing edge 11 being in contact with this sealing edge 11 from below and the Deeper sealing edge 11 b associated edge of the rotary valve 8 rests on this sealing edge 11 b from above.
