Definitions

  • the invention relates to a roof vent designed as a roof covering plate with a central, dome-shaped dome, which is greater in height than its width and smaller than its length.
  • a roof vent of this type is known from DE-OS 2 128 035.
  • the dome towering over the roof covering plate consists of pagodas or stepped roof-like attachments made of e.g. Sheet.
  • the top attachment is perforated on the ceiling to form ventilation slots.
  • the object of the invention is to improve roof ventilators of the specified type in terms of construction and ventilation technology.
  • a generic roof vent is designed as a roof covering plate, which is characterized by a simple structure and favorable conditions with regard to effective ventilation.
  • stabilization In concrete terms, the procedure is such that the apex area of the dome, which is designed as an end piece of a ventilation connection pipe, is designed as a ventilation grille. It does not require any special additional component.
  • the integral lattice continues in the form of the shape of the stabilizing struts over the area forming the ventilation cross-section.
  • the lattice elements which are expediently oriented in the longer direction of extension of the dome, lead to an extremely streamlined, largely swirl-free mouth of the opening area.
  • Such material webs forming the ventilation grille create a stable bond immediately after the component is removed from the mold. There is also no visual or visual disturbance, since the silhouette of the cathedral can be followed.
  • the ventilation grille is designed in a cap that overlaps the dome and is integral with the ventilation connection pipe .
  • the possible angle adjustment of the roof covering plate for vertical alignment of the ventilation connection pipe is given in an equally favorable manner.
  • Such a cap does not protrude significantly beyond the cathedral, which is also quite compact.
  • the corresponding overhang is practically only with a material thickness or thickness of the cap.
  • the corresponding waiver of the exposed, generally quite high chimney-like shape of the ventilation upper part also turns out to be more favorable in relation to storm-related loads or mechanical loads resulting from the snow load. If rain, etc. is to be prevented from getting into the ventilation pipe, this can be done Opening, i.e. ventilation grille overlaid with a cover cap of the same shape as the dome above the ventilation grille.
  • the arrangement above the ventilation grille is such that the required air exchange is maintained to a sufficient extent. A finger-wide spacing from the top of the cap is generally sufficient.
  • the ventilation grille has two spokes lying in the direction of the longitudinal direction of the dome, between which a bushing as a plug-in receptacle for a retaining pin of the cover cap overlapping the ventilation grille, designed to match the contour or shape, .
  • the bushing fulfills an additional function by connecting the rather long spokes like a material bridge, expediently in the center area of the spokes. Since, on the other hand, the bush is seated on spokes that are limitedly movable, in any case not rigid, freely tensioned, there is an advantageous, adaptive evasive movement with a holding pin that is not exactly axially aligned.
  • such a holding pin can be provided with latching projections, for example in such a way that its plug-in active end has a cross recess, the clear width of which provides the escape space necessary for the latches to retreat.
  • the transverse diameter of the elliptical ventilation grille opening corresponds approximately to that of the ventilation connection pipe and the longitudinal diameter of the ventilation grille opening runs into the circular cross section of the ventilation pipe via a funnel-shaped sliding surface.
  • the corresponding overlap position can be realized on both diametrically opposite sides.
  • the cover cap is designed like a helmet and forms a stepped cap screen on the eaves side.
  • the cut back vis-à-vis the helmet-like cap body forms a preferred air exchange surface, while the cap's overlap zone also promotes the corresponding all-round air exchange, but creates a larger overlap zone due to the much deeper helmet rim compared to the rainwater flowing down the eaves side.
  • the eaves-side transverse zone of the cap and / or the cover cap be designed with steps that protrude to the side. Such steps located in the preferred ventilation section avoid storm-driven blowing up of the running rainwater against the inner opening; the steps rather convey an outward flow towards the foot of the cathedral.
  • the roof covering plate 1, designed as a roof ventilator D, is designed in terms of its basic structure like the other roof covering plates (roof tiles) in order to fit optically well into the surface area of a roof.
  • An upward-facing dome 2 extends from the roof covering plate 1, which is profiled in the manner of the roof tile. It is the same as the roof covering plate 1 and extends in the central region thereof. In relation to the profile of the roof covering plate, the dome 2 extends in the plane of a central rib 3, which is convexly curved upwards and extends in the direction of inclination. Since the floor plan of the dome 2 also partially includes the adjacent flat parts 4 of the roof covering plate, the result is an oval, but in the height direction different connection or transition area, which has a beneficial effect on the stability of the dome 2.
  • the dome 2 is longer than its width in the direction of inclination of the roofing plate 1.
  • the height of the dome 2 is greater than the width and smaller than the length of the dome. It is a double-curved formation, the essentially parallel transverse walls of the dome forming flat side walls 5 in the base region thereof, but these transverse walls tapering in a dome shape in the upper region. There is therefore a greater curvature in the longitudinal direction than in the transverse direction.
  • the radius R determining the curvature of the longitudinal curvature is based approximately at the intersection of the diagonals of the basically rectangular roof covering plate. This radius point is labeled x.
  • the radius point of the transverse curvature is designated y and extends on a circular arc around the radius point x.
  • the radius R 'starting from the radius point y is half the length of the radius' R starting from the radius point x.
  • This apex region circumscribing the opening ⁇ is designed as an end piece of a ventilation connection pipe 6.
  • the dome wall and the tube wall merge into one another, preferably while maintaining the same wall thickness, which can be quite thin here due to the polydirectional orientation of the wall parts, which leads to a high stiffening effect.
  • the opening ⁇ forms the frame Ra of a ventilation grille 7.
  • the ventilation grille 7 has two spokes 8 lying in the direction of the longitudinal extent of the dome 2.
  • the upper edge of the vertically aligned spokes 8 takes a course corresponding to the curvature of the dome 2.
  • the spokes 8 clearly extend vertically into the opening ⁇ and are also convexly curved on the underside. From Fig. 8 it is clear that the two spokes 8 run parallel. Your intermediate space 9 is spaced apart, which is also essentially maintained on the outside of the spokes from the slightly curved section of the frame Ra there.
  • the opening O which is designed like a mouth and merges into the ventilation connection pipe 6, has an oval or, as shown, rather elliptical outline, the longer axis of the ellipse lying in the direction of inclination of the roofing plate 1.
  • the transverse diameter of the elliptical ventilation grille opening ⁇ is approximately equal to that of the ventilation connection pipe 6 or slightly below it.
  • the diameter of the longer ellipse axis exceeds the pipe diameter. Therefore, the area of the ellipse that forms the opening merges into a kind of funnel T.
  • the funnel T opens outwards.
  • the funnel T could be assigned symmetrically, an embodiment is selected in the exemplary embodiment such that the eaves-side bend of the elliptical opening ⁇ cuts off somewhat smaller, that is to say it has a shorter connection to the cross-sectional area 6 ′ of the ventilation connection pipe 6 there.
  • the funnel T thus adjoins at an acute angle with a slight slope on the ridge side.
  • the funnel-shaped mouth shape is therefore on the eaves-side half of the cylindrical ventilation pipe cross-section higher.
  • the ridge-side sliding surface formed by the funnel T bears the reference number 10, the other, shorter 10 '.
  • the ends of the spokes 8 are rooted in both.
  • the dome 2 is assigned a helmet-shaped cover cap 11. This covers the top of the dome 2 with vertical overlap of the frame Ra so that, for example, driving rain cannot get into the opening ⁇ .
  • the cap 11 has a shape that is largely adapted to the curvature of the dome 2 or has the same shape, so that only one ventilation gap 12 remains between the top of the dome and the inside of the cap 11.
  • a ventilation gap 12 can be provided on all sides, but is at least located in the area of a screen 13 formed on the cover cap.
  • the zone underneath can be referred to as window 14, because starting from the ends of the screen, side walls 15 of the cover cap extend with greater coverage of the opening ⁇ nearby areas of the side walls 5 of the cathedral.
  • a laterally touching support system between the side walls 15 and the corresponding side walls 5 can be used and, for example, the edge of the cap facing away from the screen 13 can be lifted off the top of the dome again.
  • a bush 16 is seated between the spokes 8 of the ventilation grille 7.
  • the latter is appropriately molded to the said spokes and expediently also has their height.
  • the geometrical axis of the bushing 16 runs approximately parallel to that of the ventilation connection pipe 6.
  • the bushing 16 forms a plug-in receptacle for a holding pin 17.
  • the latter extends from the underside of the cover cap 11 and is also molded there from the same material. It enables the centered assignment and merges into a spacer collar 18 on the ceiling, which is placed on the upper end face of the sleeve 16.
  • the plug-in section of the holding pin 17 has a cross slot. This results in four latching hooks with an outwardly facing latching lug 19 which overlap the lower end edge of the sleeve 16.
  • the shield 13 of the helmet-like cover cap 11, which is molded on the eaves side, is stepped.
  • the individual, essentially equally spaced steps have the reference number 20. They extend parallel to the approximately horizontally running screen edge. This primarily results in a material-saving component. But not only the screen 13 of the covering cap 11 has the steps 20 described, but also the transverse zone of the dome 2 on the eaves side.
  • the steps in this regard are designated by 21. Like the steps 20 of the cap 11, they continue into downward sections 20 'and 21', which extend downward to the side of the parts. In the case of the dome 2, this has the advantage that water driven up by storm hits the steps 21, which then discharge the rain water laterally and prevent it from getting into the ventilation gap 12 or into the area of the window 14.
  • FIG. 9 now specifies a version in which the ventilation connection pipe 6 is not seated directly on the dome 2, but in the interest of compensating for inclination on a cap 22 which is pivotably guided on the dome 2. Accordingly, the ventilation grille 7 also sits in this overlapping the dome 2, with the air connection tube 6, a one-piece cap 22.
  • the cap 22 is designed like a second dome with a molded-on air connection tube 6, which can be tilted onto the dome 2.
  • the other reference numbers are used analogously without repetition of text.
  • the lower edge of the cap results from FIG. 9 in a dotted line and is designated by 23. At the level of the radius point x there is a physical, horizontal folding axis aligned parallel to the eaves plane.
  • a fastening tab 26 extends from the underside of one side of the dome. It is a sectoral section with an arc slot 27 lying on the edge and concentric to x. This is penetrated by a clamping screw 28 seated on the air connection pipe 6. It can be a wing screw, via which the respective position is fixed with the interposition of a clamping washer.
  • the dome zone of the roof covering plate 1 is drawn lower on the ridge side.
  • the corresponding retraction bears the reference number 29, so that the cap 22 can dip relatively deep there.
