Description

The invention relates to a roof duct with adjustable inclination according to the preamble of claim 1.

With the subject of DE 90 04 653 U1 a vent pipe venting device has become known in which the vent pipe seated above the roof surface is designed to be adjustable in inclination in relation to the plane of the roof surface.
The inclination is adjusted by the fact that the vent pipe sitting above the roof surface has a widening at its foot end which is spherically curved and rests on a cylindrical pipe which is arranged fixed to the roof.

This results in a swivel bearing between the upper exhaust pipe and the lower, roof-mounted fastening pipe, whereby an inclination setting is given. The disadvantage of this known inclination setting, however, is that only small inclination angles can be achieved because, due to the spherical bulge at the foot end of the pipe sitting above the roof surface, only maximum inclination angles in the range of 15 ° are possible.

The two tube parts touching one another accordingly form an inclined plane, one tube being designed to be pivotable about a pivot axis to the other, roof-mounted, lower tube.

the DE 29512647 U1 shows a further inclination adjustment device for roof outlets, in which the upper, roof-distant pipe is connected in a sealed manner with a spherical cap, the lower open end of which covers an oppositely directed upper spherical cap, so that the upper, roof-remote pipe with its spherical cap sealed to it is exposed on the lower, roof-fixed, fixed spherical cap is pivotable and can be locked in certain selected pivot positions.

However, the disadvantage of the known inclination setting is that only a limited inclination setting is possible and that two interlocking spherical caps, whose surfaces must be designed to be pivotable and slidable with respect to one another, are associated with high manufacturing and assembly costs and high maintenance costs.

The angle of inclination to the roof surface is very limited because the interlocking spherical caps are only inclined to a limited extent up to a maximum angle of inclination of approx. 30 ° to 40 °.
In the case of steeper roofs, with this type of inclination setting, it is possible to rotate the spherical caps against each other by 180 ° in order to also enable adaptation to steep roofs and to different inclinations of steep roofs. It remains, however, that there is only a very limited inclination setting with relatively complicated assembly means.

Also the AT 502 483 B1 is limited to the seating of two spherical caps, which are matched to one another in terms of their curvature, whereby the inclination is determined with a locking screw which engages through a curved elongated hole in one of the spherical caps.

In which goes back to the same applicant DE 20 2013 003 354 U1 describes an adjustment shoe provided with lamellas, which is fixed at its one end to the roof surface and at its other end is fastened to the opposite end of the roof surface via flexible lamellae which can be moved relative to one another. This results in a flexible adjustment shoe with adjustable inclination, through whose interior the pipe lead-through is guided.

Also the DE 10 2011 000 944 A1 discloses two spherical caps seated on top of one another, which again have the disadvantage that only small inclination angles are given.

The invention is therefore based on the object of further developing an inclination-adjustable roof duct of the type mentioned at the outset in such a way that, with a significantly smaller number of parts, a simple and operationally reliable inclination setting is possible, which has much larger setting ranges.

To solve the problem, the invention is characterized by the technical teaching of claim 1.

An advantageous feature of the present invention is that in a roof-mounted duct pipe which is connected to the roof-mounted, incline-adjustable section of the pipeline, at least two opposing bending tabs are arranged, which are plastically bendable, and of which at least one bending tab can be displaced in its longitudinal extension and is designed to be lockable in relation to the other bending tab.

Thus, at least one bending tab is designed to be displaceable and lockable in relation to the other, fixed bending tab, the inclination-adjustable roof duct thus formed being covered in a sealed manner by a flexible tube.

With the given technical teaching there is the advantage over the prior art that a very simple inclination-adjustable roof duct is now proposed, in which at least two opposing sheet metal brackets are arranged in a roof-mounted duct pipe, of which at least one plastically bendable bracket in the direction of their Is attached longitudinally displaceable and lockable in the roof-mounted duct. The bending tabs form a frictional connection with the attached flexible tube and determine the bending direction of the flexible tube.

In a further development of the invention, it can be provided that the opposite bending tab, which is firmly attached to the roof-mounted lead-through pipe, is also designed to be displaceable and lockable in the direction of its longitudinal extension at the time.

In the following description, however, the invention only describes the embodiment in which at least one of two opposing bending straps is connected in the direction of its longitudinal extension in the manner of a longitudinal guide so that it can be displaced and locked in the roof-mounted duct. In a preferred embodiment, this longitudinal guide is designed as an elongated hole formed in the longitudinal direction, to which a clamping fastening is assigned, which preferably consists of two detachable and lockable clamping screws arranged at a mutual distance from one another.

Instead of the longitudinal guide with an elongated hole and a clamping screw which crosses the elongated hole and which rest on a clamping plate that rests against the rear of the flexible tab, it is possible in another embodiment to design the longitudinal guide as a toothed elongated hole and a spring-loaded engagement element in the teeth of the elongated hole to intervene, which then engages according to the displacement in different tooth locations of the slot guide and can be locked there.

It is a particularly simple construction principle that is based on the knowledge that if you connect the upper ends of the spaced-apart flexible tabs to parts of the blow-out head, e.g. with a hood receiving tube assigned to the blow-out head, then an upper fixed fastening point between the two upper bending tabs located at a distance from one another are provided, the lower fastening point of one bending tab being firmly attached to the roof-mounted duct, while the opposite end of the bending tab located there is designed to be displaceable and lockable.

If, in this constellation, the displaceable bending tab is now released in its clamping fastening and displaced in the direction of its longitudinal extension, then the entire arrangement bends by exactly the distance by which the displaceable bending tab was displaced with respect to the fixed bending tab, whereby - if there is a plastic bend - the mutual bending of the bending tabs is maintained in relation to the fixed hood receiving tube or other parts of the blow-out head.

It is therefore a particularly simple inclination setting that takes place automatically, so to speak, without the need for a bending tool, because the required inclination setting is achieved simply by shifting one bending tab in relation to the other, fixed bending tab.

It goes without saying that instead of two opposite bending tabs, more than two opposite bending tabs can be used, e.g. two fixed bending tabs arranged at a mutual circumferential distance from one another, opposite to which the longitudinally movable and lockable bending tab is opposite.

Generally speaking, it is a clampable sliding guide which results in an inclination setting when the one sliding and lockable bending tab is moved.

Of course, in another embodiment it is also possible to provide more than one displaceable bending tab with a corresponding slot guide instead of the one displaceable bending tab. Although this leads to increased effort during assembly, it results in a superior strength in the arrangement of the entire blow-out device.

The invention is therefore not limited to the comparison of two opposite bending tabs.

It is particularly advantageous that the roof guide tube fixed to the roof has a press-fit bead onto which the aforementioned flexible tube is pressed. This press-in bead also serves at the same time to press the roof lead-through pipe into a recess in a roof-mounted fixing plate. This has the advantage that the entire adjustment device for the at least one movable and lockable flexible tab is below the roof level, i.e. it is not visible from the outside. It can be operated from the inside of the roof surface and does not result in a raised structure above the roof surface that is exposed to the weather.

Accordingly, a seal is achieved between the roof lead-through pipe and the roof-mounted fixing plate in the area of this press-in bead that runs all the way around, with a lower, foot-side press-in surface of the flexible pipe also being pressed into this press-in bead.

Another advantage is that a flexible pan exposed to the weather can be placed on the roof-mounted fixing plate, and this flexible pan also has a recess that is aligned with the recess in the fixing plate below, so that the encircling press-in bead in the area of the pipe jacket of the Lead-through tube also connects the flexible pan and the underlying fixing plate to one another and seals the two alignments and recesses against one another. The invention is not limited to the arrangement of a flexible pan forming the water-bearing surface. In a further development it can be provided that the flexible pan is at least partially or completely covered by suitable roof tiles, the roof guide tube then protruding from an opening in the roof tile layer with its upper end beyond the press-in bead.

In 1 is the roof duct according to the invention 1 shown in an exploded view, with a first roof-fixed fixing plate 2 with assigned rows of holes 3 is attached directly to the roof structure. In the area of the fixing plate 2 is a recess 4th intended. Align to this recess 4th is another recess 6th in a flexible pan above 5 formed, wherein this flexible pan can preferably consist of a weatherproof, water-repellent flexible material, such as a plastic material, which a plastic bend of the flexible pan 5 to any roof conditions.

This flexible pan can 5 can be adapted to any roof shape and the water-bearing surface 7th is suitable that on it to drain rainwater from the roof structure using a suitable laxative.

In a further development of the invention, it can also be provided that the flexible pan, which is sufficient in and of itself 5 on their surface at least partially or completely by additional roof tiles 8th is covered, according to the drawing 1 these roof tiles 8th are only partially shown and in reality the entire area or only parts of the area of the flexible pan 5 can cover.
In this case - in the presence of roof tiles 8th - then lies the roof tile level 21 on the water-bearing surface 7th the flexible pan 5 on. The weather side 9 is then through the top of the additional roof tiles 8th educated.

According to the invention, a preferably cylindrical lead-through pipe extending through the roof structure is provided 10 made of a plastic or metal material is provided, which at its upper end has a press-in bead running all the way round 11 has, which for sealing in the area of the two mutually aligned recesses 4th , 6th serves and in which at the same time also a lower circumferential press-in surface 20th a flexible pipe 19th engages, so that the duct pipe with a suitable pressure tool 10 together with the flexible pipe 19th and the two plates 2 , 5 is pressed waterproof.

It is advantageous if the in 2 shown clamp fastening 16 for clamping the longer flexible tab 14th below the roof surface, ie below the fixing plate 2 , comes to rest, because then the entire inclination adjustment on the part of the clamp fastening 16 can be made below the roof level. Accordingly, there are also those of the clamp fastening 16 assigned clamping screws 18th below the fixing plate 2 .

The duct 10 is preferably designed as a cylinder tube and consists of a plastic or metal material. It can also have any other desired shape, such as an elliptical, triangular or polygonal shape, where it is only assumed that this shape is sealed with a suitable pressure tool with at least one or more press-fit beads 11 into the associated recesses 4th , 6th can be pressed in.

Through the inside of the pipe 12th of the duct 10 the element leading out over the roof surface is now passed through. In the exemplary embodiment shown, the roof duct is used to attach a blow-out head 23 , the blow-out head in a manner to be described in more detail with the upper end of the flexible pipe 19th and a hood receiving tube arranged thereon 22nd connected is.

In the 1 it is also shown that the one bending tab 14th an elongated hole in the direction of its longitudinal extension 15th has, which by the clamp fastening 16 using two clamping screws 18th can be determined, while opposite a fixed flexible tab is preferred 13th is arranged, which is also plastically bendable.

Both bending tabs 13th , 14th have associated pressure joining points at their upper ends 30th on, with which they are firmly attached to the inside, e.g. of a hood mounting tube 22nd , which are connected in 6th is shown. Instead of arranging such pressure joining points 30th Other fastening measures can also be used, such as adhesive fastening, screw fastening or welding fastening.
The invention is not based on the sliding guide of a plastically bendable flexible bracket 14th limited; In another, not shown embodiment, it can be provided that also the other, inherently fixed and immovable flexible tab 13th is also designed to be displaceable in the direction of its longitudinal extension.

For the sake of simpler description, however, only the clamp fastening of the one plastically bendable flexible tab is discussed below 14th described. Instead of the arrangement of a blow-out head 23 like him in 3 is shown, any other elements could be passed through the lead-through pipe, such as electrical lines, which are provided in particular for solar systems, water-carrying lines and the like.

Here shows the 2 a detailed representation of such a possible clamp fastening, with two clamping screws arranged at a distance from one another 18th the elongated hole 15th the bending tab 14th reach through and on the back of the bending tab is a clamping plate 17th arranged from which the clamping bolts extend. By tightening the clamping nuts, an adjustable fastening of the displacement of the flexural tab is achieved 14th in the area of the duct 10 achieved.

3 shows the possible inclination settings, the same parts being provided with the same reference numerals. It can be seen that the pipe angle specifying the inclination 29 in relation to a vertical 27 at a very wide angle of inclination 28 is adjustable.
In preferred refinements, this angle of inclination can even be the angular position 0, ie parallel to the plane of the fixing plate 2 result or result in an angle of 90 °, which then gives the pipe angle 29 with the vertical 27 flees.
In 3 are further details of a discharge head 23 shown, where it can be seen that the aforementioned hood receiving tube 22nd from its outside by a hood tube 24 sealed is encompassed and the hood tube 24 in the hood head 25th is introduced, which is in its top in a known manner from a rain cover 26th is covered.
In this way a flow of exhaust air is created in the exhaust head 23 and is protected against the ingress of rain and can be blown freely into the atmosphere.

For the in 4th shown clamp fastening 16 the same reference numerals apply as on the basis of 2 has been described. It can also be seen here that the press-fit surface 20th of the flexible pipe 19th into the press-fit bead 11 reaches in and the two plates 2 , 5 together with the duct 10 are pressed.

5 FIG. 4 shows a perspective view of the assembled arrangement, while FIG 6th and 7th show various detailed representations.

the 6th shows that the elongated hole 15th along the entire length of the bending flap 14th advantageously extends and that the length of the bending tab 14th is chosen to be significantly greater than the length of the opposite, preferably fixed, but plastically bendable flexible tab 13th is trained. Furthermore, the 6th that the bending tab 14th assigned clamp fastening 16 below the fixing plate 2 and can therefore be easily operated from the underside of the roof level.
This representation results from 7th .

the 8th shows that when you loosen the right clamping fastening 16a, that of the bending tab 14th is assigned, the left clamping attachment 16b remains undissolved, now a displacement of the bending tab in the direction of the arrow 33 is possible, whereby the change in length between the shorter bending tab is automatically due to this shift 13th and the longer bending flap 14th changed so that the pipe angle 29 in the directions of the arrows 31 , 32 is continuously adjustable.
After the required roof pitch has been set, the clamp fastening 16a is thus determined again, whereby the pipe angle 29 remains fixed.
The two opposite clamps are also in 9 shown.

the 10 and 11 each show a longitudinal section through the assembled arrangement of the roof duct, the 11 the view in the direction of arrow X in 8th shows while the 10 the sectional view in the direction of arrow XI in 8th represents. The same reference numbers have been used for the same parts.

the 12th shows a modification of the design of two opposing bending tabs 13th , 14th , where it can be seen that the length-adjustable bending tab 14th now also two fixed bending tabs 13a, 13b can be assigned.
In a representation not shown in the drawing, it can also be provided that two adjustable bending tabs 14a, 14b arranged parallel to one another and lying next to one another can be present, each of which has either a single bending tab 13th opposite is or two fixed bending tabs 13a, 13b.
the 13th and 14th now show the adjustment principle according to the invention, where in 13th it is shown that, starting from a vertical mounting position, the left bending tab 13th and is slidably fixed in the clamp, which is symbolized by an earthing symbol.
the 13th also shows that when loosening the clamp fastening, not shown in detail, for the flexible tab 14th now a shift in the direction of the arrow 33 is possible and with this shift the flexible tube, which is firmly connected to the upper end of the two bending tabs, automatically bends (see the pressure-joining points 30th ) so that the flexible pipe is in the bending direction 36 bends.

This bending state is in 14th shown, based on the basic setting according to 13th now the required bending has been achieved by the plastically bendable bending tab 14 'is now fixed in its final shifted position and at the same time the fixed bending tab 13' was also plastically bent, so a fixed inclination in the bending direction 36 to enable. The flexible tube 19 'is now also bent.
the 10 and 11 still show that the top edge of the duct 10 as a pipe edge 35 is referred to, while the upper edge of the hood receiving tube 22nd with the reference number 34 is referred to as the pipe edge. In the formation of the bending tabs 13th , 14th is advantageous if these can be bent plastically. They can consist of a plastically bendable metal material or a plastic material or a plastic-metal composite material. They can also be reinforced with fiberglass.
