Position held clamped.

Based on the preferred embodiment of the parent application, the pivoting part can next to the floor pan also comprise at least a portion of the preferably perforated walls of the ventilation shaft. As is known from the parent application, strip arrangements in a so-called blind cover used, these strips are parallel to the floor pan. Powder snow and airborne dust can thus be used properly be held and recorded.

But it is not absolutely necessary that the wall of the ventilation shaft perforations in the form of Slits or bores, but it is also possible that the ventilation shaft from a rigid Part and the articulated pivot part, with a protruding edge of the pivot part leaving an airway encloses the lower edge of the rigid part like a collar.

Further features of the subclaims are set out in the following description of exemplary embodiments explained. The description is based on the drawing, which has the following figures:

The following description refers to exemplary embodiments, the improvements of the ventilation devices according to parent application P 31 06 278.4 concern. To the parent application mentioned in this Embodiments described and the other disclosure of the registration documents of the parent application

is referred to. As far as necessary for understanding, the disclosure of the parent application should also apply to the present application.

FIG. 1 of the present application shows an embodiment and form of use in a representation similar to that of FIG. 1 of the Stainman application. The ventilation device is designed as a roof vent which includes a base plate 1 to be fastened in the area of the roof surface, which has the shape of a roof tile, so that it can be used without further ado in the association of the roof covering. The base plate 1 is penetrated by an opening 2, onto which a vent 3 protruding above the roof level rises. The ventilation nozzle 3 is covered with a hood 5, ie no air or water can penetrate directly from above. ^{A ventilation duct 4 1} adjoins the opening 2 at the bottom, which is normally inserted into the opening from below and can be fastened to the ventilation socket 3 with the aid of latching devices. The whole system accordingly has an upper part, consisting of ventilation nozzle 3 and hood 5, a middle part, namely the base plate 1 in the form of a roof tile, and an insert that can be pushed in from below, the so-called ventilation shaft 4 '.

It should be noted that the design of the ventilation shaft can easily be transferred to other ventilation devices. For example, for flat roofs, a base plate to be introduced into the roof skin can be used in a completely flat form. The ventilation shaft can be cuboid, prismatic, round or oval. A special aspect is that the ventilation shaft 4 ¹ can adapt to existing and known ventilation devices, so that it can take the place of the insert box or connecting piece that is normally to be provided.

The ventilation duct 4 'consists of one with the base plate connected apron 30, attached to the fastening devices 9, for example resilient hook webs are so that the apron 30 can be inserted from below into a corresponding ventilation device according to FIG is. The side walls 31, 32 of the apron are characteristically cut out in the form of an obtuse angle, wherein at the intersection of the angle leg, which lies in the middle of the skirt 30, bearing bores 33, 34 are given. The end walls 35, 36 of the skirt part 30 are pulled down so far that they coincide with the alignment lines of the side walls.

They are slightly curved outwards.

A pivoting part 39 comprising a floor pan 38 is articulated into the apron 30 via the bearing bores 33, 34, tied together. The pivoting part 39 is designed as a sector cutout with a cutout angle A of approximately 160-180 °. For this purpose, the pivot part 39 has walls 40, 41 which are spaced apart by the floor pan 38 and webs 42 being held. The floor pan has a slightly raised edge 38 'in which melt water collects can. The melt water can be discharged via a drain connection 43, which can also serve as a handle can be deducted (sales not shown).

Similar to the set wall of the object of the main application are the opposing walls 40, 41 of the pivoting part with spaced one above the other, in a horizontal plan view overlapping strips 14 ', 15' inclined towards the inside of the manhole educated. The strips 14 ', 15 "are similar to in the case of a blind cover, they are mirror images of each other (see FIG. 3), with the upper edge of a strip above the lower edge of the strip above. In Figures 2 and 3 are the strips shown as horizontal bars; it is also possible,

to deviate from this shape insofar as slight curvatures or corrugations are possible. The angle of inclination of the strips 14 ', 15' is preferably at an angle of 30-60 ° to the horizontal. It has been shown in tests that this inclination reliably prevents the clumping in the ventilation duct 4 ¹ snow is passing through the slot opening 18 'between two strips and can reach the outside. The spacing and inclination of the strip arrangement is chosen so that there is adequate ventilation. The distance between the upper edges of the strips is therefore between 10 and 30 mm, for example, although these dimensions are not intended to be binding, but may vary depending on the application, ventilation requirement, throughput and similar details for a person skilled in the art. In the present case, a total of nine such strips are arranged one above the other. The volume lying in the interior of the pivoting part 39 between the lower edges of the strips is of course free, since it has to absorb the snow or dust that may fall through the opening 2 downwards.

The overlapping strips are held in place by brackets 20 ', 21' extending from the webs 42,

which, in turn, have longitudinal struts 45 on their upper side through the bores 43, 44 to a stable construction be united.

Similar to the Stairun registration it is possible that instead of horizontal strips that overlap in plan view, the walls of the ventilation shaft are provided with holes or slots, which are covered with discs or bells.

Essential feature of the ventilation shaft described above, consisting of apron 30 and pivoting part 39 is that the pivoting part 39 is adjusted as required can be that the floor pan is horizontal, d. H. the inclination of the floor pan in relation to the base plate is adjustable. With the aid of a bolt (not shown) penetrating the bores 33, 34, 43, 44 the part 39 is held on the part 30. After pulling out the bolt, the part 39 can be removed.

Figure 4 shows a somewhat modified embodiment, namely an apron 30 with more pulled down Transverse web walls and a different inclination of the strips 14 ", 15". The floor pan 38 'is not in the Vertex of element 39, but shifted laterally.

FIG. 5 shows a modified embodiment in which the ventilation duct 4 ″ consists of a rigid part 50 and a pivoting part 51 articulated thereon, the pivotability being achieved with the aid of coinciding bores and a penetrating bolt 52 collar-like the lower edge 54 of the rigid part 50, although an air path (arrow P, P ¹ ) is left This device, designed in the manner of known automatic feeders, in which the feed constantly trickles down, is also suitable for reliably catching powder snow and in particular flying dust and preventing it from penetrating the interior of the house Perforations through the slots or bores, the air flow occurs through the openings d he spaced, overlapping edges 53, 54.

Figure 6 finally shows; From a clock f ung s shape, consisting of a box-type ventilation duct 4 ^'11, a downwardly oscillatingly hangenes pivot member 57 connects to the that sector as a circular cylinder

is cut and is articulated via a pivot axis 58 on the side walls of the ventilation shaft 4 ^111. The pivot part 57 can be withdrawn ^{from the ventilation duct 4 111} via a slot 59 at which the pivot axis 58 can be pulled out. The airway is indicated by an arrow P. A sufficient path is left between the edge of the pivoting part 57 and the shaft 4 ^111.

All of the embodiments described can be used both made of metal as well as plastic, generally a plastic version because of the Corrosion resistance is given preference.
