- the two parts 42, 43 of the outer wall 16 of the sheet member I Ia are in particular undercuts.
- the two parts 42, 43 of the outer wall 16 of the sheet member I Ia can be connected to each other, for example via a tongue and groove connection. This allows a particularly simple and reliable positioning of the two molded parts of the sheet member I Ia each other.
- the two parts 42, 43 of the outer wall 16 of the sheet member I Ia can be fixed together by means of brackets 44. They can also be glued together.
- connection of the two parts 42, 43 may be provided in the region of the connecting line a bead.
- the bow-inner part 43 is connected to the preferably integrally formed sleeve 21, in particular integrally formed therewith.
- a single guide element 28 is provided in the curved element 11a.
- Another number of guide elements 28i is also possible with the arch element 1a.
- the guide element 28 is formed in particular simply curved. In particular, it has a substantially rectilinear profile parallel to the axis of curvature. In this alternative, it may be advantageous to form the guide element 28 separately from the outer wall 16 of the arcuate element I Ia. The guide element 28 can then be introduced into the interior 17 of the arch element 11a and fixed there.
- fixing webs 45 are arranged in pairs on the inner side of the outer wall 16 of the curved element 1 la. Between the two fixing webs 45 of a pair, a receiving groove 46 for receiving the guide element 28 is formed.
- the guide element 28 can be glued in particular in the receiving groove 46.
- a latching of the guide element 28 with matching locking means, in particular in the region of the sleeve 21 is also possible.
- the guide element 28 is preferably integrally integrated into the outer wall 16 of the arch element 11a (see FIG. 9). In particular, it has in each case a side section 47, which continues the inner contour of the outer wall 16 substantially smoothly, in particular free of edges.
- the side portion may have a groove 48 at the end for receiving the first part 42 of the outer wall 16.
- the second part 43 of the outer wall 16 is repeatedly stepped in this area, in particular double-stepped design.
- the guide element 28 is thus fixed between an end edge 49 of the first part 42 and a step 50 in the second part 43. It may additionally be fixed by a second stage 51 in the second part 43.
- the end edge 49 of the first part 42 engages in particular in the groove 48 in the side portion 47 of the guide element 28 a.
- connection of the elbow element 11 according to the preceding description with a connection piece, in particular in the form of a flat channel element 56, will be described below with reference to FIGS. 10 to 12.
- the flat channel element 56 can also be connected to the curved element I Ia.
- the flat channel element 56 is inserted into the end-side sleeve 21 of the bow element 11. It overlaps in the flow direction substantially over the entire length of the sleeve 21 with this.
- the inside of the flat channel element 56 forms a substantially smooth, in particular edge-free, continuation of the inside of the arch element 11.
- a sealing element 57 shown by way of example in FIG. 12 is arranged in the area between the flat channel element 56 and the sleeve 21, arranged.
- the sealing element 57 is mounted on the flat channel element 56. It is inserted together with the flat channel element 56 in the sheet member 11, in particular the sleeve 21. It leads to a dense, in particular liquid-tight, preferably gas-tight connection between the flat channel element 56 and the arch element 11.
- the sealing member 57 is made of a flexible material.
- the sealing member 57 is preferably made of an elastic material. It can be made of rubber in particular. It encloses a free end of the flat channel element 56 circumferentially completely. It has on the one hand a slightly inwardly projecting edge 58. The edge 58 abuts in a mounted on the flat channel member 56 state of the sealing member 57 at an end-side free edge of the flat channel member 56 at.
- the edge 58 comes to rest in the inserted into the sheet member 11 state of the flat-channel element 56 between the free edge of the flat-channel element 56 and an abutment shoulder 59 formed by the sleeve 21.
- the sealing member 57 has three circumferential sealing lips 60. In particular, it has at least one sealing lip 60. It may also have two or more than three sealing lips 60.
- the sealing lips 60 may have different heights. They lead to a dense, in particular a liquid-tight, preferably a gas-tight connection between the flat-channel element 56 and the sealing element 57, and thus between the channel or pipe element and the arch element eleventh
- the sealing element 57 can form a component of the arch element 11 or I Ia or a component of the flat or round duct element. In particular, it can form a component of the assembly set 40 as a separate element.
- the sealing element 57 in particular in the ventilation system 1, can lead to a tight connection of a flat or round-channel element to the curved element 11.
- the radius of curvature of the guide elements 28i in a flow cross-sectional plane is in particular in the range of 50 mm to 500 mm.
- the guide elements 32 have a length in the range of 5 cm to 20 cm.
- the gearing 33 can provide a displacement in the range of 5 cm to 20 cm.
- the base plate 31 in particular has a construction height in the range of 5 mm to 15 mm, in particular in the range of 8 mm to 12 mm. It thus simultaneously serves as a spacer between the arch element 11 and a building or furniture structure on which the sheet element 11 is arranged.
