    Description Technical Field The invention relates to a device for forming a closure for a ventilation pipe, in particular under a solar panel on a roof of a building. The present invention further relates to a method for forming an end of a ventilation pipe.
    PRIOR ART When planning and building a solar system on a roof of a building, ventilation pipes of all types and dimensions can be a problem. Often, these are vapor pipes that prevent a system from being installed over the entire surface. If ventilation pipes are left out, the area of the solar system is reduced, which reduces the power output of the solar system. Furthermore, the already controversial appearance of solar systems suffers from such a gap.
    So far, such pipes were often simply cut deep enough, including pipe surround, and the solar panels were mounted above them. However, there is a problem with this approach that the solar panels are attacked and damaged in the long term by the channel gases escaping. Furthermore, with this approach, the tightness of the closure between the pipe socket and the pipe is no longer guaranteed. Under certain circumstances, water can get into the sub-roof or even inside the building.
    A second approach is sometimes that a construction worker creates an elaborate new version with the corresponding pipe dimensions and sloping ceilings. A transition to a non-commercial flat duct with the same air capacity as the existing pipe is essential. Since the space between the roof and the solar panels is small in most cases, the pipe must be shortened in order to be able to install a corresponding flat duct.
    It is possible, but also very complex and costly, to lay the extractor tube inside the building.
    [0006] Adapters have already been proposed to solve this problem. US 2017/0 261 145 A1 (Solar Roof Jack Ine.), For example, proposes an adapter with which a ventilation pipe on a roof can be diverted to a pipe system so that a solar panel can be installed above the original pipe end. The adapter comprises a base plate and a deflection element, a sealing element being arranged between them. The base plate has a large opening through which the end of a tube can be inserted. The end of the tube extends into the deflection element, it being possible for another tube of the line system to be inserted into the deflection element at an angle without the two tubes touching one another. The sealing element has an opening with a sealing lip, the opening having a slightly smaller diameter than the tube which is pushed through.
    A disadvantage of this solution is that an additional line system must be installed below the solar system, the additional line system having to be passed somewhere in the solar system between the panels for ventilation. On the one hand, this affects the optics of the solar system and, on the other hand, leads to a not inconsiderable additional effort when installing the solar system.
    As a further example, US 2016/0 102 460 A1 (SolarCity Corporation) discloses a device with which a ventilation pipe on a roof can be diverted into a ventilation box which is arranged between solar panels. A rubber collar is pushed over a shortened ventilation pipe, after which a branching element is connected to the collar. The branch element is pushed over or into the pipe. The connection between the ventilation box and the branching element is established via a flexible cable. The branching element can also be designed in the form of a box placed on the shortened tube.
    A disadvantage of this solution is that the ventilation box must be arranged between the solar panels, which has a negative effect on the appearance of the solar system and - to a small extent - on its usable area. Furthermore, a flexible line must be laid between the branch element and ventilation box, which means additional effort.
    DESCRIPTION OF THE INVENTION The object of the invention is to create a device belonging to the technical field mentioned at the outset, which can be assembled quickly and easily. Furthermore, the device is intended to enable a ventilation pipe to be closed on a roof, which does not impair the usable area or the appearance of a solar system mounted on the roof.
    The solution to the problem is defined by the features of claim 1. According to the invention, a device for closing off a ventilation pipe comprises a collar into which the ventilation pipe can be inserted. The collar has a circumferential wall, a first opening and a second opening, which lies opposite the first opening. The device also has a hollow body with an at least partially circumferential wall and a first side surface and a second side surface opposite the first side surface. A ver
    CH 715 249 A2 connection piece is in particular detachably attached to the first side surface of the hollow body. The connecting piece has a cross section which essentially corresponds to the cross section of the second opening of the collar. The hollow body has a ventilation opening which is arranged in the at least partially circumferential wall or the second side surface. The connecting piece is inserted into the second opening of the collar or slipped over the circumferential wall of the collar in the region of the second opening in order to releasably connect the flat hollow body to the collar. Arranged inside the collar is a sleeve made of a flexible and stretchable material, which is connected all round to the peripheral wall of the collar, the ventilation pipe being able to be passed through this sleeve.
    The hollow body can be arranged between a surface of the roof and at least one solar panel of a solar system, so that the usable area of the solar system and its appearance are not impaired. The hollow body can also be designed such that the flow cross-section is not smaller than the ventilation pipe, so that there is no impairment of the suction effect and the air outlet. By using a sleeve made of a flexible and stretchable material, the device for ventilation pipes with different diameters and different outlet angles can be used on a roof or on roofs with different inclinations, since the sleeve can be easily adjusted thanks to its flexibility and elasticity.
    In the present application, the term “termination of a ventilation pipe” is understood to mean a device which is arranged at one end of a ventilation pipe and which protects the ventilation pipe from external influences, in particular the weather. The closure of the ventilation pipe should in particular prevent or reduce the penetration of dirt or rainwater into the ventilation pipe. The end of the ventilation pipe forms a transition with which gases can flow from the ventilation pipe into the atmosphere or the end can serve as a transition to another pipe or duct.
    [0014] The device according to the invention is preferably used on a roof of a building. Alternatively, however, the present device can also be used on other parts of a building, for example on a wall.
    [0015] The device according to the invention is preferably used to close a ventilation pipe under a solar panel. Alternatively, however, the device can also be used under other structures on a roof or a wall of a building, such as, for example, a remote facade or the like.
    The device according to the invention can be used in particular as a replacement for an existing termination of a ventilation pipe, for example when retrofitting a solar system on a roof of a building. In this case, the existing end of the ventilation pipe is preferably removed, the ventilation pipe is shortened to a certain length, and the device according to the invention is then attached as a new end of the ventilation pipe.
    [0017] The collar preferably has a round cross section. Alternatively, however, the collar can also have a different cross section, such as, for example, elliptical, square, rectangular or polygonal.
    The diameter of the collar is chosen such that it can be arranged over ventilation pipes with different diameters. The diameter of the collar is preferably between 100 mm and 400 mm, particularly preferably between 200 mm and 300 mm. The diameter of the collar can be constant over the entire length of the collar, that is to say over the entire distance between the first opening and the second opening. Alternatively, the diameter of the collar can change over the length of the collar. The diameter of the collar preferably decreases from the first opening in the direction of the second opening. The diameter in this case preferably decreases continuously, that is to say that the collar can be in the form of a truncated cone. As an alternative, the diameter of the collar can also be reduced discontinuously, in particular in steps.
    The circumferential wall of the collar is preferably designed to be airtight and / or watertight. This means that any connection points in the circumferential wall must be designed so that a corresponding tightness is achieved. The collar is preferably made in one piece, for example by production by means of extrusion, injection molding, die casting or extrusion. As an alternative, however, the collar can also consist of two or more individual parts which are joined together in a airtight and / or watertight manner, for example by means of gluing or welding. [0020] The first opening and the second opening of the collar are preferably open.
    The first side surface and the second side surface of the hollow body are preferably spaced apart from one another, the first and second side surfaces in particular being parallel to one another. Alternatively, however, the two side surfaces can also have different shapes or sizes and cannot be arranged parallel to one another.
    Due to the at least partially circumferential wall, the flat hollow body thus encloses a volume. The first and second side surfaces preferably have the same shape and the same size. The first and second side surfaces are preferably designed as rectangles. The distance between the first side surface and the second side surface is smaller in relation to side edges of the first and second side surfaces. In the case of an intended arrangement of the device, in which the first side surface of the hollow body is essentially parallel to the roof or to a wall of a building, the hollow body has a height that is less than its length or width. The dimensions of the two side surfaces and their distance from one another are preferably such
    CH 715 249 A2 chose that a flow cross section is available to a gas emerging from the ventilation pipe, which is at least the same size or larger than the flow cross section in the ventilation pipe.
    The hollow body is preferably designed as a flat channel. This means that the hollow body has a much greater length than width (and height).
    The at least partially circumferential wall preferably encloses the entire circumference of the hollow body. Alternatively, the at least partially circumferential wall does not enclose the entire circumference of the hollow body. This means that at least a portion of the circumference of the hollow body has no wall between the first and the second side surface.
    Preferably, the first and the second side surface and the at least partially circumferential wall are firmly connected. In a particularly preferred embodiment, however, the first and second side surfaces are detachably connected to one another. This simplifies the assembly of the device, since loosening the side surfaces gives a fitter access to the volume which is enclosed by the hollow body. Particularly preferably, the at least partially circumferential wall has means with which the first and second side surfaces can be detachably connected to one another. The at least partially circumferential wall is preferably in two partial walls, a first partial wall being connected to the first side surface and a second partial wall being connected to the second side surface. The first and the second partial wall preferably have guides which can be pushed into one another in order to releasably connect the first side surface and the second side surface to one another. So the hollow body is in two halves, which can be pushed into one another and apart.
    The hollow body preferably has a web which projects into the interior of the hollow body and extends in the longitudinal direction over at least part of the length of the hollow body. As a result, a higher stability of the hollow body can be achieved. The web is preferably dimensioned such that after the partial walls of the hollow body have been put together, it rests flush on a collar of the connecting piece. As a result, the connecting piece can be connected to the hollow body without tools.
    With the connecting piece, the hollow body can be releasably connected to the collar. The connecting piece can either be inserted into the collar or placed over it.
    In a preferred embodiment, the first side surface has a passage in which the connecting piece can be inserted, so that the connecting piece can be detachably connected to the first side surface. In this embodiment, the connecting piece preferably has a flange at one end, which prevents the connecting piece from slipping through the passage.
    In a particularly preferred embodiment, the first side surface has tabs arranged on the circumference of the passage and projecting from the first side surface. During assembly, the first side surface is first placed on the second opening of the collar, so that the collar is coaxial with the passage and the tabs rest on its outer circumference. The connecting piece is then pushed through the passage, the collar being held in a clamping manner in the region of the second opening between the tabs and the connecting piece. The second side surface can then be connected to the first side surface.
    The connecting piece is preferably made of the same material as the hollow body. Alternatively, however, the connecting piece can also consist of a different material. Preferred materials for the connecting piece are metals such as steel, in particular chromium-nickel steel, or thermoplastic or thermosetting polymers.
    [0031] A gas flowing through the ventilation pipe and the hollow body can then escape through the ventilation opening into the atmosphere or into a further pipeline. If the partially circumferential wall does not encompass the entire circumference of the hollow body, the ventilation opening is formed by that part of the circumference of the hollow body in which there is no wall. If, however, the at least partially circumferential wall encloses the entire circumference of the hollow body, a ventilation opening is formed separately on the at least partially circumferential wall or the second side surface. Furthermore, the vent opening can have connecting means with which the vent opening can be connected to a further pipeline, for example if the gas is to escape into the atmosphere above a solar panel.
    In a further embodiment, the hollow body can also consist of two or more sections which are in particular at an angle to one another. For example, the hollow body can consist of two sections which are at right angles to one another, the connecting piece being arranged in a first of the two sections and the ventilation opening in the second section. With such a “kink” it is possible to place the ventilation opening higher than the connecting piece.
    The cuff is preferably ventilated and / or watertightly connected to the collar by gluing or welding. A passage opening, which has essentially the same shape and size as the cross section of the ventilation pipe, is preferably cut out in the cuff, for example by a mechanic, for the passage of the ventilation pipe.
    Preferably, the circumferential wall of the collar has at least one channel which is arranged just above, that is to say in the direction of the first opening, the connection between the collar and the collar. Through this
    CH 715 249 A2 at least one channel can drain water, in particular condensed water, which collects between the hollow body and the sleeve inside the collar.
    Preferably, the cuff is made of a flexible and stretchable polymer. The flexible and stretchable polymer is preferably an elastomer. Because the sleeve is made of a flexible and stretchable polymer, a ventilation pipe can be passed through the sleeve at almost any angle. Due to the extensibility, it is also possible to pass ventilation pipes with different diameters through the sleeve.
    The sleeve is preferably made of ethylene-propylene-diene rubber (EPDM). Due to the high weather and ozone resistance and the good chemical resistance, EPDM is particularly well suited for use in the device according to the invention.
    The sleeve is preferably in the form of a substantially flat surface or a truncated cone. When present as an essentially flat surface, the sleeve is preferably designed as a film which is stretched within the collar. The film is preferably arranged circumferentially at right angles to the circumferential wall of the collar. The design as a truncated cone enables the sleeve to be adapted as easily as possible for carrying out ventilation pipes with different diameters, since the truncated cone can simply be cut off at the corresponding height, which has the same cross-sectional area as the ventilation pipe.
    [0038] The cuff preferably has a passage opening for the ventilation pipe. This simplifies the assembly of the device according to the invention, since it no longer has to cut a passage opening into the cuff during assembly.
    The cuff preferably has markings which enable the cutting out of a passage opening or the enlargement of a passage opening for a ventilation pipe with a specific diameter. The markings are designed, for example, as concentric rings, in each of which the diameter of a ventilation pipe that passes through the specific ring is indicated. The markings are preferably such that their diameter is smaller than the diameter of the corresponding ventilation pipe. It is thereby achieved that when the ventilation pipe is passed through the passage opening, the sleeve lies sealingly around the ventilation pipe. The diameter of the markings is preferably at least 10%, in particular, however, at least 25% smaller than the diameter of the corresponding ventilation pipe.
    The planar hollow body is preferably made of steel, in particular of chromium-nickel steel. As a result, the shape of the hollow body is stable and weatherproof. Alternatively, however, the hollow body can be made from another material, such as, for example, from a polymer, in particular from ethylene-propylene-diene rubber (EPDM).
    The collar preferably consists of a polymer, in particular of ethylene-propylene-diene rubber (EPDM). The thickness of the circumferential wall of the collar is preferably greater than the thickness of the sleeve. Alternatively, however, the circumferential wall of the collar and the cuff can be of the same thickness.
    [0042] The collar preferably has two differently shaped sections between the first opening and the second opening.
    In a first section which is adjacent to the first opening, the collar is preferably in the form of a truncated cone converging in the direction of the second opening. This makes it easier to insert a ventilation pipe into the collar.
    Preferably, the collar is in the form of a cylinder in a second section adjacent to the second opening. This facilitates the releasable connection between the collar and the first side surface of the hollow body, since the collar meets the first side surface essentially at right angles.
    In a preferred embodiment, the collar has a combination of a truncated cone in the first section and a cylinder in the second section. In this embodiment, the truncated cone extends into the cylindrical section and thus forms the sleeve, which is frustoconical.
    A stiffening element, in particular in the form of a section of a rigid tube, is preferably arranged in the collar in the region of the second opening. As a result, the collar can be stiffened in the region which is releasably connected to the hollow body, with which a stronger and more stable connection can be created.
    The stiffening element preferably consists of a thermosetting or thermoplastic polymer, in particular of polyethylene.
    The present application also relates to a method for attaching a closure to a ventilation pipe, in particular on the roof of a building. In a first step, a device is presented as described above, the hollow body being detached from the collar. The ventilation tube is then inserted through the first opening of the collar and carried out through the cuff in such a way that the ventilation tube does not protrude from the second opening of the collar. Then the collar is connected to the hollow body.
    If the sleeve has no passage opening for the ventilation pipe or an existing passage opening for the ventilation pipe is too small, a passage opening is made or an existing passage opening is enlarged before the ventilation pipe is inserted into the collar.
    CH 715 249 A2 The following detailed description and the entirety of the claims result in further advantageous embodiments and combinations of features of the invention.

    3 shows a schematic longitudinal section through a second embodiment of a device according to the invention;
    FIG. 4 shows a three-dimensional, schematic exploded drawing of the device according to the embodiment of FIG. 2.
    In principle, the same parts are provided with the same reference symbols in the figures.
    WAYS OF IMPLEMENTING THE INVENTION FIG. 1 shows a schematic longitudinal section through a first embodiment of a device 1 according to the invention, which is arranged on a roof 12 and connected to a ventilation pipe 11. The device 1 thus forms a termination of the ventilation pipe 11 on the roof 12. A solar panel, for example, could be arranged above the device 1.
    The device 1 has a collar 7 with a circumferential wall. In the exemplary embodiment shown, the collar 7 is in the form of a cylinder, the collar 7 having a first opening 9 and a second opening 10. A collar 8 is arranged inside the collar 7 and is fastened all round to the circumferential wall of the collar 7. The ventilation pipe 11 is inserted through the first opening 9 into the collar 7 and pushed through a passage opening 18 of the sleeve 8. The collar 7 rests on the roof 12 with its first opening 9. The collar 7 also has a channel 21, which is arranged just above the sleeve 8 in its circumferential wall and allows water, for example condensed water, to drain from the collar 7.
    The collar 7 lies with its second end 10 on a first side surface 3 of a hollow body 2 of the device. The collar 7 is detachably connected to the first side 3 by means of a connecting piece 13. In the embodiment shown, the connecting piece 13 is in the form of a separate element which is inserted into a passage 6 in the first side surface 3. In order to prevent the connecting piece 13 from slipping through the passage 6, the connecting piece 13 has a flange 19.
    In addition to the first side surface 3, the hollow body 2 comprises a second side surface 4 which lies opposite the first side surface 3 and is spaced apart therefrom. Furthermore, the hollow body 2 has an at least partially circumferential wall 5. In the embodiment shown, the right side of the hollow body 2 in the viewing direction is open, that is to say it is designed without a wall 5, this open side forming a ventilation opening 14. There is a volume V within the hollow body. The volume V should have the same or a larger flow cross-section as the ventilation tube 11 for a gas emerging from the ventilation tube 11. The first side surface 3 and the second side surface 4 of the hollow body 2 are detachably connected to each other, so that the hollow body 2 can be disassembled for the purpose of assembly or disassembly of the device 1. For this purpose, the at least partially circumferential wall 5 is double-walled, a first partial wall 5a being firmly connected to the first side surface 3 and a second partial wall 5b being firmly connected to the second side surface 4. The two part walls 5a, 5b can be pushed into one another in order to put the hollow body 2 together. For this purpose, the two part walls 5a, 5b have suitable form-fitting means (not shown) which enable the part walls 5a, 5b to be pushed into one another in a guided manner.
    Within the hollow body 2 there is a web 22 which projects into the volume V of the hollow body 2 and which ensures additional stability of the hollow body 2. The web 22 is fastened to the second partial wall 5b in the embodiment shown and extends almost over the entire length of the hollow body 2. The dimension of the web 22 is selected such that it is flush with the collar when the two partial walls 5a, 5b are assembled 19 of the connecting piece 13 is on. As a result, the connecting piece 13 can be connected to the hollow body 2 without tools.
    Fig. 2 shows a schematic cross section through a hollow body 2 according to the embodiment of Fig. 1 with inserted connector 13. On this figure it can be seen that the web 22 has the shape of a U in cross section and thus on both sides of the collar 19 of the connecting piece 13 is on. The web 22 is connected to the second partial wall 5b in particular by welding.
    CH 715 249 A2 [0058] FIG. 3 shows a schematic longitudinal section through a second embodiment of a device 1 according to the invention. In contrast to the embodiment according to FIG. 1, the collar 7 in this embodiment is divided into two sections with different shapes. A first section 15, which extends from the first opening 9, is in the form of a truncated cone. A second section 16, which extends from the second opening in the direction of the first section 15, is in the form of a cylinder. The cuff 8 is also present in a different configuration in the embodiment shown: the cuff 8 has the shape of a truncated cone, the cuff 8 being designed as a continuation of the truncated cone of the first section 15. Such a collar 7 can be formed, for example, by joining a truncated cone to a cylinder, the truncated cone forming both the first section 15 and the sleeve 8 and the cylinder forming the second section 16. The truncated cone and the cylinder can be connected to one another by means of gluing or welding. The connection between the truncated cone and the cylinder is carried out in such a way that it has at least one gap, which serves as a channel for the drainage of water from the cylindrical part of the collar. This can prevent water, in particular condensation, from collecting between the sleeve 8 and the hollow body 2.
    In the area of the second opening 10, the collar 7 has a stiffening element 20, which is arranged within the collar 7 and ensures a more stable connection between the collar 7 and the connecting piece 13. In the embodiment shown, the stiffening element 20 is designed as a section of a rigid tube arranged inside the collar 7.
    Another difference from the embodiment according to FIG. 1 is that a plurality of tabs 17 are arranged on the circumference of the passage 6, which protrude from the first side surface 3. These tabs 17 make it possible to improve the connection to the collar 7, since the tabs 17 are held in a clamping manner between the connecting piece 13 and the circumferential wall of the collar 7. The tabs 17 are also bent outwards at their free end, so that they additionally enter into a positive connection with a lower edge of the stiffening element 20.
    Furthermore, the vent opening 14 is arranged in the second side surface 4 of the hollow body 2 in this embodiment.
    4 shows a three-dimensional, schematic exploded drawing of the device 1 according to the embodiment of FIG. 3. At the same time, the method according to the invention can be explained with reference to FIG. 4: As the first step, the collar 7 is detached from the hollow body 2, wherein for this purpose the connecting piece 13 is removed. At most, the two side surfaces 3, 4 must be separated from one another beforehand in order to gain access to the connecting piece 13. The collar 7 is then guided to the ventilation pipe 11, which may need to be shortened to a suitable length beforehand. The ventilation pipe 11 is inserted through the first opening 9 into the collar 7 and then passed through the through opening 18 of the sleeve 8.
    Next, the first side surface 3 of the hollow body is placed on the second opening 10 of the collar 7 such that the second opening 10 is concentric with the passage 6 and the tabs 17 on the inside of the circumferential wall of the collar 7 in the region of the second Fit opening 10. Then the connecting piece 13 is inserted through the passage 6 and the second opening 10 into the collar 7 until the flange 19 comes into contact with the first side surface 3. By inserting the connecting piece 13, the tabs 17 are held clamped between the circumferential wall of the collar 7 in the region of the second opening 10 and the connecting piece 13. In a last step, the second side surface 4 is connected to the first side surface 3, the partial walls 5a, 5b being pushed into one another by means of corresponding guides (not shown).
