    DESCRIPTION OF THE EXEMPLARY EMBODIMENTS In the following, identical or identical components, in particular components that perform the same function, are identified with the same reference symbols.
    1 shows a schematic illustration of an exemplary embodiment of two structural elements 10 for a housing structure. The structural elements 10 are a structural element 10a and a further structural element 10b. The structural elements 10 for a housing structure 16 of a heating device are characterized in that they are at least essentially, in the exemplary embodiment shown completely, in the form of foam parts 12. In the case shown, the structural elements 10 are designed as thermoplastic foam castings 14. This reduces the manufacturing costs.

    Patent Office In the case shown, the structural elements 10 are c-shaped. Correspondingly, the structural elements form a housing structure 16 which is open towards the front in a lower region. This in turn allows maximum accessibility for a service technician during maintenance or repair of a heating device.
    The structural elements 10 represent characteristic components for the housing structure 16 of a heating device. They fulfill a supporting function for further components of the housing structure 16 of a heating device.
    The structural elements 10 have a multiplicity of receptacles 18 for housing structural elements 20, further housing elements 22 and functional units 24, as a result of which the structural elements 10 can be flexibly expanded.
    In the case of this invention, the housing structural elements 20 are components of the housing structure 16. In the exemplary embodiments shown, these are the structural elements 10 themselves, a connecting element 26 and an air box 34, which form the housing structure 16.
    2 to 4 correspondingly schematic representations of the exemplary embodiment of the structural elements 10 from FIG. 1 with the connecting element 26 are shown. In the exemplary embodiment shown, the connecting element 26 is a tubular element 28. The tubular element 28 is formed from metal in the case shown. In addition, the tubular element 28 is formed like a bow in the case shown. This ensures particularly high stability.
    As can be seen from FIGS. 2 to 4, the connecting element 26 or the tubular element 28 is inserted into recesses 30 provided for receiving the connecting element 26, which are introduced into the structural elements 10. The structural elements 10, or the structural element 10a and the further structural element 10b, are thereby connected to one another.
    The pipe element 28 has bends 32. The recesses 30 provided for receiving the tubular element 28 are designed such that the connecting element 26, or the tubular element 28, can be inserted into the structural elements 10 with a precise fit. As a result, the structural elements 10 are connected to one another in a more stable manner, and they can no longer be rotated relative to one another.
    5 to 7 show a schematic illustration of the exemplary embodiment of the structural elements 10 from FIG. 1 with a connecting element 20 and an air box 34. The air box 34 is mounted on the structural elements 10, which are connected by means of the connecting element 26.
    The air box 34 has on both sides two tab-like connecting means 36, in the case shown a front, tab-like connecting means 38 and a rear, tab-like connecting means 40. The tab-like connecting means 36 are provided to establish a positive connection with the structural elements 10.
    The front, tab-like connecting means 38 is continuously flat, while the rear, tab-like connecting means 40 has a hole 42. The hole 42 is provided to enable fixation, for example by a snap connection by means of a snap hook.
    As already mentioned, the air box 34 is mounted on the structural elements 10 in accordance with the exemplary embodiment shown in FIGS. 5 to 7. The tab-like connecting means 38 are inserted into the corresponding receptacles 18, in the case shown the recesses 44 provided for receiving the tab-like connecting means 38.
    After insertion of the tab-like connecting means 36 into the recesses 44 provided for receiving the tab-like connecting means 38, the air box 34 is moved by a lateral displacement, in the case shown a forward displacement

    Structural elements 10 fixed. The rear, tab-like connecting means 40 is fixed in such a way that further displacement is no longer possible. The fixation takes place by means of a latching element, in the case shown a snap hook, which snaps into the hole 42 of the rear, tab-like connecting means 40 and prevents a further displacement of the air box 34 to the rear.
    Alternatively, it would also be conceivable to design the tab-like connecting means 36 and / or the recesses 44 provided for receiving the tab-like connecting means 36 in such a way that the fixing takes place by a displacement to the rear. It would also be conceivable that a fixation takes place exclusively or in addition to the lateral displacement by means of a screw connection or rivet connection.
    1 to 7 accordingly represent an assembly sequence for a method for assembling a housing structure 16 for a heating device. The method is characterized above all by the fact that the following method steps take place:
    A) inserting the connecting element 26, in the case shown the tubular element 28, into the structural elements 10 for connecting the structural elements 10 to one another, [0058] b) plugging the air box 34 onto the structural elements 10.
    [0059] This enables particularly quick and simple assembly.
    In addition, the housing structure on the back of the air box 34 has a wall suspension, which is not shown here. The wall suspension is intended to enable wall mounting of the housing structure, for example by means of a screw fastening. The structural elements 10 in turn have support geometries 21, which are intended to support the housing structure 16 in a lower region against a wall.
    As already mentioned, the structural elements 10 can also be flexibly expanded by additional housing elements 22 due to the large number of receptacles 18. Correspondingly, FIGS. 8 to 11 show schematic representations or schematic representations of parts of the structural elements 10 with further housing elements 22.
    In the cases shown, the further housing elements 22 are components 46 for connecting a hydraulic unit, a device 48 for receiving an operating part 50, a locking element 52, a further locking element 58 and outer walls 53 of an outer housing.
    FIG. 8 shows a schematic illustration of a part of the exemplary embodiment of the structural element 10a from FIG. 1 with a component 46 for connecting a hydraulic unit. Component 46 for connecting a hydraulic unit is inserted into a recess 54 provided for receiving this component 46. Analogously, a further component 46 is attached for connecting a same hydraulic unit to the further structural element 10b. The components 46 for connecting such a hydraulic unit are accordingly provided to attach the hydraulic unit to the structural elements 10 or the housing structure 16. As a result, the structural elements 10 or the housing structure 16 fulfill a supporting function for such a hydraulic unit.
    FIG. 9 shows a schematic illustration of the exemplary embodiment of the structural elements from FIG. 1 with a device 48 for receiving the operating part 50. The device 48 for receiving the operating part 50 is introduced into the recesses 56 provided for receiving this device and is correspondingly attached to the structural elements 10.
    Furthermore, it can be seen in FIG. 9 that the raster elements 52 can be introduced into the structural elements 10. The raster elements 52 shown are intended to fix the device 48 for receiving the operating part 50 to the structural elements 10. The latching elements 52 themselves are attached to the device 48 for receiving the operating part 50 and can be in the recess provided for receiving these raster elements 52

    Patent office mungen 58 can be inserted. A particularly simple assembly of the device 48 for receiving the operating part 50 can thus take place.
    FIG. 10 shows a schematic illustration of a part of the exemplary embodiment of the further structural element 10b from FIG. 1 with a further latching element 58. The further locking element 58 is introduced into a receptacle 60 corresponding to this further locking element 58. Analogously to this, a structurally identical, alternatively also structurally similar, possibly a mirrored, further latching element 58 is introduced in a receptacle 60 corresponding to this, or structurally similar, structurally similar, further latching element 58. In the case shown, the further latching elements 58 are provided for fixing a front cover on the underside of the housing structure 16 by means of a latching mechanism.
    The further locking elements 58 are themselves also introduced and fixed in the receptacles 60 by means of a locking mechanism. Correspondingly, the further latching elements 58 each have an elevation 62, while the receptacles 60 corresponding to the further latching element 58 have openings 64 provided for latching in the elevations 62.
    The recesses 56 provided for receiving the device 48 can also be seen in FIG. 10. It can also be seen that the further latching element 58 has an extension 61 with a clip-like structure 64. When the further latching element 58 is introduced, the clip-like structure 64 is simultaneously introduced into the recess 56 provided for receiving the device 48 via the extension 61. There, the clamp-like structure 64 forms a receptacle 65 for an axial and / or rotary bearing of the device 48. This enables at least one part of the device 48 for receiving the operating part 50 to be rotatably supported and thus opening the device 48 with the operating part 50 is made possible.
    11 shows a schematic illustration of the exemplary embodiment of the device structure 16 from FIG. 6 with an air box 34, which is closed in the case shown, a pressure equalization vessel 66 and outer walls 53 of an outer housing. The outer walls 53 each have a lower guide element 68 and an upper guide element 70. When the outer walls 53 are mounted on the device structure 16, the guide elements 68, 70 are arranged on a side of the outer walls 53 facing the device structure 16. The lower guide elements 68 are designed as hook-like, in the case shown U-shaped, sheet metal parts 69, while the upper guide elements 70 are designed as projecting sheet metal parts 71. The lower guide elements 68 are each arranged at a lower end 78 of the outer walls 53, welded on in the case shown, while the upper guide elements 70 are formed at an upper end 80 of the outer walls 53. The outer walls 53 can also be understood as side walls in the context of this invention.
    The structural elements 10 now each have recesses 72 which are provided for receiving the lower guide elements 68. The recesses 72 are each formed as a groove 74. On the top of the air box, holding elements 76 corresponding to the upper guide elements 70 are in turn arranged, which are provided for holding the outer walls 53 at the upper end 80.
    The outer walls 53 are now mounted in such a way that they are inserted along the device structure 16 from front to back, the lower guide elements 68 being inserted into the corresponding recesses 72 of the structural elements 10 and the upper guide elements 70 being hooked in a guided manner along the holding elements 76 , This enables simplified assembly of the outer walls 53.
    FIG. 12 shows a schematic illustration of part of the exemplary embodiment of the device structure 16 from FIG. 11 with a closed air box 34, a pressure compensation vessel 66 and an assembled outer wall 53. So you can see here that that
    6.30
    AT 16 173 U1 2019-03-15 Austrian
    Patent office upper guide element 70 is hooked onto the corresponding holding elements 76.
    In addition, FIGS. 11 and 12 show a pressure compensation vessel 66 which is arranged on the structural element 10a. Here, the structural element 10a has a receptacle 82 provided for this pressure compensation vessel 66, as a result of which a stable arrangement of the pressure compensation vessel 66 is made possible.
    FIG. 13 shows a schematic illustration of a part of the exemplary embodiment of the structural element 10a from FIG. 9 with a manometer 84. It can thus be seen that the structural element 10b has a receptacle 86 provided for the manometer 84, as a result of which a simple arrangement of the manometer 84 on the structural element 10a or the housing structure 16 is made possible.
    The pressure compensation vessel 66 and the manometer 84 are functional units 24 in the exemplary embodiments shown, which contribute to the operation of a heating device.
    14 shows a schematic illustration of a further exemplary embodiment of two structural elements 10 for a housing structure 16. The structural elements 10 have essentially the same properties according to the invention as the structural elements 10 from FIG. 1.
    The structural elements 10 are also at least substantially, in the exemplary embodiment shown completely, in the form of foam parts 12. In the case shown, the structural elements 10 are also designed as thermoplastic foam castings 14, as a result of which the production costs are reduced.
    Analogous to the structural elements 10 shown in FIG. 1, the structural elements 10 shown in FIG. 13 also have a large number of receptacles 18 for housing structural elements 20, further housing elements 22 and functional units 24, as a result of which the structural elements 10 can be flexibly expanded. These are the same further housing elements 22 and functional units 24 as have already been shown and described in accordance with FIGS. 8 to 13. Alternatively, however, it is also possible to use other and / or additional further housing elements and functional units.
    15 to 17 show schematic representations of the exemplary embodiment of the structural elements 10 from FIG. 14 with a connecting element 26. The difference from the exemplary embodiment of the structural elements 10 from FIG. 1 shown in FIGS. 2 to 4 lies in the fact that the connecting element 26 is a sheet metal element 128.
    15 to 17, the connecting element 26, or the sheet metal element 128, is introduced into recesses 130 provided for receiving the connecting element 26, which in the structural elements 10, in the exemplary embodiment shown, on the rear side of the recesses 130 Structural elements 10 are introduced. As a result, the structural elements 10, or the structural element 10a and the further structural element 10b, are connected to one another, a simplified assembly of the connecting element 26 being made possible.
    The sheet metal element 128 has tab-like projections 132, which are provided to connect the sheet metal element 128 to an air box 34. Both a riveted connection and a screw connection are conceivable.
    Correspondingly, FIGS. 18 to 20 show a schematic illustration of the exemplary embodiment of the structural elements 10 from FIG. 14 with a connecting element 26, or a bleaching part 128, and an air box 34. Analogously to the exemplary embodiment from FIGS. 5 to 7, the air box 34 is also mounted on the structural elements 10 in the exemplary embodiment according to FIGS. 18 to 20. In the exemplary embodiment according to FIGS. 18 to 20, this is the same air box 34 as from the exemplary embodiment according to FIGS. 5 to
    7. Alternatively, it would also be possible to use a different or similar air box.
    The tab-like connecting means 38 of the air box 34 are also in the ge

    Patent office showed embodiment according to FIGS. 18 to 20 in the corresponding receptacles 18, in the case shown the recesses 144 provided for receiving the tab-like connecting means 38.
    18 to 20, however, after inserting the tab-like connecting means 36 of the air box 34 into the recesses 144 of the structural elements 10 provided for receiving the tab-like connecting means 38, the air box 34 is displaced by a lateral displacement, in the exemplary embodiment shown towards the rear, fixed with the structural elements 10. The air box 34 is then fixed to the tab-like projections 132 of the sheet metal element 128, as a result of which a further displacement of the air box 34 is prevented.
    In addition, it would also be possible that, as already for the exemplary embodiment from FIGS. 5 and 6, the rear, tab-like connecting means 40 of the air box 34 is fixed in such a way that a further displacement is no longer possible. The fixation could also take place by means of a latching element, for example by means of a snap hook which snaps into the hole 42 of the rear, tab-like connecting means 40, and additionally prevents the air box 34 from being moved forward. It would also be conceivable that the front tab-like connecting means 38 has a hole 42 which is fixed by means of a latching mechanism.
    14 to 20 represent, analogously to FIGS. 1 to 7, an assembly sequence for a method for assembling a housing structure 16 for a heating device. The main feature of the method is that the following method steps are carried out:
    A) inserting the connecting element 26, in the case shown, the sheet metal element 128, into the structural elements 10 for connecting the structural elements 10 to one another, b) plugging the air box 34 onto the structural elements 10.
    [0089] This also enables particularly quick and simple assembly.
