Description

[0001] Mobile living quarters for motor vehicles or trailers

[0002] The present invention relates to a mobile living structure for motor vehicles or trailers with the features in the preamble of claim 1. The invention further relates to a motor vehicle or a trailer with a living structure according to the invention as per claim 15.

[0003] Mobile living quarters for motor vehicles or trailers are known in the prior art. Since motor vehicles and trailers are limited in length and, in particular, width by applicable road traffic regulations, the living quarters installed on these vehicles or trailers, which include a living space, often feature extension modules. These extension modules can be coupled to a base module of the living quarters and, when the motor vehicle or trailer is stationary, moved from a retracted position to an extended position to expand the living space. This increases the living space and thus the comfort of the users. A corresponding living quarters with movable extension modules is known, for example, from DE 10 2015 225 269 B4. The extension modules allow the living space of the living quarters to be enlarged transversely to the longitudinal direction of the motor vehicle.However, a simultaneous increase in living space in a vertical direction, i.e., an increase in the distance between the floor and the roof of the residential structure, is not possible.

[0004] Furthermore, recreational vehicles with space expansion systems are known from DE 12 32 838 A, EP 3 747 696 A1 and DE 29 41 091 A1.

[0005] Based on the prior art, the object of the present invention is to provide an improved mobile living structure whose living space can be enlarged, in particular by relocating an extension module, both vertically and horizontally. Furthermore, the object of the invention is to provide a motor vehicle or trailer with a corresponding living structure.

[0006] The first problem is solved by a mobile living structure for a motor vehicle or a trailer according to claim 1. The second problem is solved by a motor vehicle or a trailer according to claim 15.

[0007] Advantageous embodiments of the invention are the subject of the dependent claims.

[0008] The mobile living structure according to the invention for a motor vehicle or trailer encloses a living space and comprises a base module and an extension module coupled to the base module. The extension module can be moved from a retracted position to an extended position to enlarge the living space. The movement of the extension module is essentially horizontal.

[0009] The basic module of the residential structure has three side walls and a base plate connected to these side walls. The opposing side walls are aligned parallel to the direction of displacement of the extension module and are connected by the third side wall, which is perpendicular to the opposing side walls. The extension module also has three side walls and a base plate connected to these side walls. The opposing side walls of the extension module are likewise aligned parallel to the direction of displacement of the extension module and are connected by the third side wall, which is perpendicular to the opposing side walls.

[0010] The basic module and the extension module are aligned so that their respective third side walls are positioned opposite each other. Together, the basic module and the extension module thus define the floor and side walls of the living space.

[0011] The essential feature of the invention is that the side walls of the base module, aligned parallel to the direction of movement of the extension module, and the side walls of the extension module, aligned parallel to the direction of movement of the extension module, are each coupled to a pivotable wall element. Thus, a total of at least four wall elements are provided. The wall elements of the adjacent side walls of the base module and the extension module, i.e., the side walls of the base module and the extension module that are arranged on the same side of the living structure, are operatively connected. In the retracted position of the extension module, the wall elements are in a lowered position, and a large portion of their surface area does not extend beyond the surface area of ​​the side wall to which the wall element is coupled. Therefore, in the retracted position of the extension module, the living space is not increased, or only minimally increased, by the wall elements.When the extension module is moved from the retracted to the extended position, the distance between the pivoting wall elements increases in the direction of movement. This results in the wall elements being moved into an upright position by the interaction between them. In the upright position, the height of the living structure is increased by the wall elements. A further essential aspect of the invention is that a flexible outer wall is slidably connected at its end to the side wall of the base module, which is oriented transversely to the direction of movement of the extension module, and to the side wall of the extension module, which is also oriented transversely to the direction of movement. The outer wall is designed to be flexible, and thus bendable, particularly in the direction of movement.The flexible exterior wall connects the third side walls of the base module and the extension module, which are oriented perpendicular to the direction of movement, and forms the roof of the residential structure. The flexible exterior wall interacts with the wall elements. When the extension module is retracted or the wall elements are lowered, the exterior wall rests section by section on the wall elements or the upper edges of the side walls of the base module and / or the extension module. When the extension module is moved into the extended position, the wall elements pivot into their extended position, raising the exterior wall along with them. This is made possible by the flexibility of the exterior wall and the sliding connection between the exterior wall and the third side walls of the base module and the extension module. When the wall elements are raised, the exterior wall rests section by section on them.

[0012] The combination of pivoting wall elements and the flexible outer wall according to the invention thus enables an expansion of the living space vertically. Crucially, this expansion occurs automatically by repositioning the extension module. No additional extension process is required. Therefore, the living space of the residential structure can be enlarged both vertically and horizontally by repositioning the extension module.

[0013] The wall elements are preferably quarter-circle shaped. Particularly preferably, the radius of each quarter-circle wall element corresponds approximately to the width and / or height of the side wall to which the wall element is coupled. This allows for maximum vertical expansion of the living space without increasing the width or length of the living structure in the retracted position of the extension module or in the lowered position of the wall elements. In the lowered position, the quarter-circle wall elements are arranged such that one leg of each wall element is positioned at the top edge and one leg at the side edge of the side wall to which the wall element is coupled, away from the third side wall. In the extended position of the extension module, or in the lowered position of the wall elements, the radius of each quarter-circle wall element is arranged such that one leg of each wall element is positioned at the top edge and one leg is positioned at the side edge furthest from the third side wall.In the erected position of the quarter-circle wall elements, the adjacent wall elements of the base module and the extension module preferably form a semicircle, with the flexible outer wall resting on the outer contour of the wall elements. The distance between the ground and the roof of the residential structure, formed by the flexible outer wall, thus increases from the third side walls of the base module and the extension module towards the center of the residential structure.

[0014] Preferably, the wall elements are each coupled at a coupling point to the side walls of the base module and the extension module, which are aligned parallel to the displacement direction of the extension module. The wall elements are pivotably connected to the respective side wall via these coupling points.

[0015] In particular, the coupling point is located at the right-angled corners of the quarter-circle wall elements. It is also advantageous if the coupling point is located at the upper corners of the side walls connected to the wall elements. In the lowered position of the wall elements, this ensures that the majority of their surface area does not extend beyond the outer contour of the side walls. At the same time, when erected, the wall elements extend almost completely beyond the side walls, thus maximizing the living space.

[0016] In an advantageous embodiment of the invention, the functional connection between the adjacent side walls of the base module and the extension module is designed in such a way that the wall elements are pivotably connected to one another at a coupling point. In the lowered position of the wall elements, the wall elements of the adjacent side walls of the base module and the extension module are preferably arranged one behind the other, but mirrored to each other with respect to a vertical axis of symmetry. The coupling point is preferably located in the upper central region of each of the adjacent wall elements. When the extension module is moved from the retracted to the extended position, the distance between the coupling points between the wall element and the side wall is reduced.The coupling point between the wall elements ensures that the wall elements are pivoted upwards during the relocation of the extension module and are transferred from the lowered to the erected state.

[0017] Alternatively, the wall elements of the adjacent side walls of the base module and the extension module can each be connected to each other by means of a connecting rod. This allows the adjacent wall elements to be arranged with a horizontal offset from one another. In this case, when the wall elements are erected, an opening is formed between them in the area of ​​the connecting rod. This opening can be closed with a cover plate. The cover plate can be connected to the outer wall by a hinge, so that the cover plate can be folded in front of the opening when the wall elements are erected.

[0018] Preferably, the wall elements, in their lowered position, do not project beyond the outer contour of the side wall to which they are connected, particularly not laterally. This has the advantage that the width or length of the living space is not increased when the extension module is retracted or when the wall elements are lowered.

[0019] The flexible outer wall features a honeycomb structure and is preferably made of a plastic material. This allows for an optimal balance between minimal weight and maximum load-bearing capacity. When the honeycomb structure is subjected to stress, the force is distributed across the numerous walls of the cells. This ensures the structure remains very stable despite its minimal material usage. Furthermore, the honeycomb structure provides excellent thermal and acoustic insulation.

[0020] Preferably, the flexible exterior wall is formed from separate wall units, which are connected to each other on their outer side, facing away from the living space. The separate wall units run longitudinally perpendicular to the direction of movement of the extension module. This allows the exterior wall to bend, so that it can adapt to the outer contour defined by the wall elements. The separate wall units can be formed by recesses in the exterior wall. In this case, the recesses are only deep enough to leave a connecting section between the formed wall units.

[0021] Preferably, the flexible outer wall and the side walls of the base module and the extension module, oriented transversely to the direction of movement of the extension module, each have guide elements for slidable coupling. In particular, the corresponding side walls have two dovetail slides that are slidably mounted in corresponding dovetail guides. The dovetail guides preferably extend parallel to each other and transversely to the longitudinal direction of the wall units across the entire outer wall. This allows the flexible outer wall to be moved when the wall elements are transferred from the lowered to the raised position.

[0022] Preferably, the wall elements are guided in the dovetail guides, so that the flexible outer wall adapts to the outer contour of the wall elements.

[0023] Alternatively, the flexible outer wall can also have two additional parallel recesses, with the wall elements guided in these recesses when the extension module is extended. Even when the extension module is retracted, the wall elements can already be positioned in the recesses. These recesses also run parallel to the direction of movement of the extension module and ensure that the flexible outer wall adapts to the outer contour of the wall elements.

[0024] Preferably, in the retracted position of the extension module, the flexible outer wall completely conceals the side wall of both the base module and the extension module that is oriented perpendicular to the direction of movement of the extension module. This has the advantage that the living quarters are protected from dirt and other weather influences during transport. Furthermore, complete concealment allows for a sufficient length of the flexible outer wall so that it does not detach from the connected side walls when the extension module is extended.

[0025] The basic module, the extension module, and / or the flexible exterior wall can be manufactured using a 3D printing process. This has the advantage that the residential structure can be produced cost-effectively and allows for great freedom in the design of the individual components.

[0026] The invention further comprises a motor vehicle or a trailer with a residential body according to the invention. The residential body is in particular arranged on a chassis of the motor vehicle or the trailer.

[0027] Preferably, the living structure is positioned on the motor vehicle or trailer in such a way that the extension module can be extended transversely to the longitudinal axis of the motor vehicle or trailer.

[0028] The invention is described in more detail below with reference to exemplary embodiments illustrated in the drawings. The drawings show:

[0029] Figure 1 a) to c) shows the functional principle of a residential structure according to the invention in a rear view, Figure 2 a) to c) shows a first embodiment of a trailer with a residential structure according to the invention in a retracted position of the extension module,

[0030] Figure 3 a) to c) shows the first embodiment of the trailer with a residential structure according to the invention in an intermediate position of the extension module,

[0032] Figure 5 a) to c) shows a second embodiment of the trailer with a residential structure according to the invention in a rear view and

[0033] Figure 6 a) to c) shows a flexible outer wall according to the invention in a side view, a detail view and a perspective view.

[0034] Figures 1 to 6 are technically schematic and not to scale. The same reference symbols are used for identical or functionally equivalent components, even if repeated descriptions are omitted for the sake of simplicity.

[0035] Figure 1 illustrates the functional principle of a mobile living unit 1 for a motor vehicle or trailer. The living unit 1 encloses a living space 2 and comprises a base module 3 and an extension module 4 coupled to the base module 3. To extend the living space 2, the extension module 4 can be moved from a retracted position to an extended position, with the movement taking place in a horizontal direction V.

[0036] Figure 1a) shows the mobile living unit 1 in the retracted position of the extension module 4, Figure 1b) shows the mobile living unit 1 during the relocation of the extension module 4, and Figure 1c) shows the mobile living unit 1 in the extended position of the extension module 4. The base module 3 has three side walls 5, 6, 7 and a base plate 8 connected to the side walls 5, 6, 7. The first side wall 5 and the second side wall 6 are arranged on opposite sides of the base plate 8 and parallel to the direction of relocation V. The third side wall 7 is located on the side of the base plate 8 facing away from the extension module 4 and is orthogonal to the first side wall 5 and the second side wall 6. The third side wall 7 connects the first side wall 5 and the second side wall 6.

[0037] The extension module 4 also has three side walls 10, 11, 12 and a base plate 13. The first side wall 10 and the second side wall 11 are arranged on opposite sides of the base plate 13 and parallel to the displacement direction V. The third side wall 12 is located on the side of the base plate 13 facing away from the base module 3 and is orthogonal to the first side wall 10 and the second side wall 11. The third side wall 12 connects the first side wall 10 and the second side wall 11.

[0038] The base plate 13 of the extension module 4 is arranged to be movable above the base plate 9 of the basic module 3. The side walls 5, 6, 7 of the basic module 3 and the side walls 10, 11, 12 of the extension module 4 thus define the width B and the length of the residential structure 1 (not shown in Figure 1).

[0039] In the retracted position of the extension module 4 shown in Figure 1 a), the extension module 4 is arranged almost completely within the outer contour of the base module 3. This ensures the smallest possible width B of the mobile living unit 1 during transport.

[0040] The side walls 5, 6 of the base module 3, which are aligned parallel to the displacement direction V of the extension module 4, and the side walls 10, 11 of the extension module 4, which are aligned parallel to the displacement direction V of the extension module 4, are each coupled to a pivotable wall element 15. The wall elements 15 are quarter-circle shaped and are each coupled at a coupling point 16 to the first side walls 5, 10 and second side walls 6, 11 of the base module 3 and the extension module 4. The quarter-circle wall elements 15 have a radius R that corresponds to the width BS and height HS of the side walls 5, 6, 10, 11 to which they are coupled.

[0041] In the retracted position of the extension module 4 shown in Figure 1 a), the wall elements 15 coupled to the side walls 5, 6 of the base module 3 are arranged such that a first leg 17 of the respective wall element 15 is positioned in the area of ​​the upper edge 18 and a second leg 19 is positioned in the area of ​​the side edge 20 of the side wall 5, 6 coupled to the wall element 15, which faces away from the third side wall 7.

[0042] The wall elements 15 of the adjacent side walls 5, 6, 10, 11 of the basic module 3 and the extension module 4, i.e. the wall elements 15 of the adjacent side walls 5 and 10 as well as 6 and 11, are each in an effective connection and are coupled together at a coupling point 21.

[0043] Due to the displacement of the extension module 4 shown in Figure 1 b), the distance A between the adjacent coupling points 16 is reduced. The coupling point 21 ensures that the wall elements 15 are pivoted upwards from their lowered position in the direction of the image, thus away from the base plates 8, 9, 13, during the displacement of the extension module 4.

[0044] Figure 1 c) shows the mobile living structure 1 in the extended position of the extension module 4. Here, wall elements 15 have been pivoted into their final erected position and form a semicircle over the width B of the living structure 1.

[0045] The mobile living unit 1 also features a flexible outer wall 22, not shown in detail in Figure 1, which forms the roof of the living unit 1. In the extended position of the extension module 4 shown in Figure 1 c), the flexible outer wall 22 rests on the outer edges of the wall elements 15 arranged in a semicircle. By repositioning the extension module 4, the living space 2 is thus enlarged not only horizontally but also vertically, i.e., in height. A larger living space 2 offers greater comfort for the users of the living unit 1.

[0046] Figure 2 shows a first embodiment of a trailer 23, which has a mobile living unit 1 according to the invention, in the retracted position of the extension module 4. The living unit 1 is positioned on a frame or chassis 24 of the trailer 23. The living unit 1 is arranged on the trailer 23 such that the displacement direction V of the extension module 4 is oriented transversely to the longitudinal axis LA of the trailer 23.

[0047] Figure 2a) shows the trailer 23 in a rear view. The basic structure of the base module 3, extension module 4, and wall elements 15 corresponds to the structure shown in Figure 1. Figure 2a) shows the flexible outer wall 22. The outer wall 22 is slidably connected at its end to the side wall 7 of the base module 3, which is oriented transversely to the displacement direction V of the extension module 4, and to the side wall 12 of the extension module 4, which is oriented transversely to the displacement direction V of the extension module 4, and forms the roof of the living quarters 1. In the retracted position of the extension module 4, the outer wall 22 rests on the upper legs 17 of the quarter-circle wall elements 15.

[0048] Figure 2b) shows the trailer 23 in a side view and Figure 2c) in a perspective view. The figures show that, in the retracted position of the extension module 4, the flexible outer wall 22 conceals the side walls 7, 13 of the base module 3 and the extension module 4, which are oriented transversely to the direction of displacement V. This protects the living quarters 1 from the elements and damage during transport.

[0049] Figure 3 shows the first embodiment of the trailer 23 in an intermediate position between the retracted and extended positions of the extension module 4. Figure 3a), which shows a rear view of the trailer 23, illustrates that the wall elements 15 are pivoted from the lowered position to the raised position during the relocation process of the extension module 4. This, in turn, causes the flexible outer wall 22 to be moved upwards in the direction of the image, together with the wall elements 15. The outer wall 22 rests partially on the wall elements 15, so that the wall elements 15 and the outer wall 22 are functionally connected.

[0050] The displacement of the outer wall 22 is made possible by the movable coupling of the outer wall 22 with the side walls 7, 12 of the basic module 3, which are oriented orthogonally to the displacement direction V.

[0051] Extension module 4. This coupling can be seen in Figure 3 b), which shows the trailer 23 in a side view. On the side walls 7, 12 of the living quarters 1, dovetail slides 32 are arranged on the outside, parallel to each other. The flexible outer wall 22 is slidably coupled to the dovetail slides 32 and can be moved vertically upwards or downwards.

[0052] Figure 3c) shows the trailer 23 in perspective. Figure 3c) further illustrates that the flexible outer wall 22 extends from the third side wall 7 of the base module 3 to the third side wall 12 of the extension module 4, thus forming the roof of the living quarters 1. The flexible outer wall 22 is supported and guided by the wall elements 15.

[0053] Figure 4 shows the first embodiment of the trailer 23 in the extended position of the extension module 4. Figure 4a) shows a rear view of the trailer 23. The wall elements 15, when in the raised position, each form a semicircle on the front and rear of the living quarters 1. Thus, in the extended position of the extension module 4, the living space 2 is increased both horizontally in its width B and vertically in its height H. Overall, the living space 2 can be increased by more than 200% compared to the retracted or lowered position by the inventive design of the living quarters 1 in the extended position of the extension module 4 and the raised position of the wall elements 15.

[0054] In the extended position of the extension module 4, the flexible outer wall 22 rests over 90% of its length, in particular completely, on the outer contour of the semicircles formed by the wall elements 15. This can also be seen in the side view shown in Figure 4 b) and in the perspective view of the trailer 23 shown in Figure 4 c).

[0055] Figure 5 shows a second embodiment of a trailer 23 with a living module 1 according to the invention. Figure 5a) shows the trailer 23 in a rear view. In contrast to the first embodiment shown in Figures 2 to 4, the base module 3 has a greater width BG than the extension module 4. The width BG of the base module 3 is also greater than the radius R of the wall elements 15. This is one way to enlarge the living space 2 enclosed by the living module 1 by widening the base module 3. The extension module 4 and the wall elements 15 do not need to be adjusted in their dimensions.

[0056] The coupling points 16 between the side walls 5, 6 of the base body 3 and the wall elements 15 are arranged such that the quarter-circle wall elements 15, with their curvature, abut the side wall 7 of the base body 3, which is arranged orthogonally to the displacement direction V. This ensures that the flexible outer wall 22 is guided by the curvatures of the wall elements 15 during the transition between the retracted and extended positions of the extension module 4. In particular, this prevents any offset at the transition between the third side wall 7 of the base body 3 and the curvature of the wall elements 15. This can be seen in the intermediate position shown in Figure 5 b).

[0057] Figure 5c) shows the trailer 23 of the second embodiment in the extended position of the extension module 4. Due to its function, the wall elements 15 are also shown in their erected position. In this embodiment, the adjacent wall elements 15 do not form a perfect semicircle when the extension module 4 is extended. An opening 25 is formed between the adjacent wall elements 15 due to the greater width BG of the base module 3. This opening can be closed with a cover plate (not shown). The cover plate can be connected to the outer wall 22 by a hinge, so that the cover plate can be folded in front of the opening 25 when the wall elements 15 are erected.

[0058] Figures 5 b) and c) further show that, unlike in the first embodiment, the adjacent wall elements 15 are not functionally connected to each other by a coupling point 21, but are connected to each other by means of a connecting rod 26. The connecting rod 26 essentially fulfills the same function as the coupling point 21 of the first embodiment, but simultaneously enables the formation of the opening 25 between the wall elements 15.

[0059] Figure 6a) shows a section of the flexible outer wall 22 in the area of ​​the transition between the third side wall 7 of the base module 3 (not shown here), which is oriented transversely to the direction of displacement V, and a wall element 15. Figure 6b) shows the detail AA of Figure 6a). The flexible outer wall 22 has a honeycomb structure 27 and is made of a plastic. This allows for an optimal compromise between the lowest possible weight and the highest possible load-bearing capacity. When the honeycomb structure 27 is subjected to a load, the force is distributed across the many walls of the honeycomb. Thus, the structure remains very stable despite being made of very little material. In addition, the honeycomb structure 27 provides good thermal and acoustic insulation.

[0060] The flexible outer wall 22 is formed from separate wall units 28, the wall units 28 being connected to each other on their side 29 facing away from the residential structure 1. The width BA of the recesses 30 formed between the wall units 28 preferably increases in the direction of the residential structure 1. The separate wall units 28 run transversely in their longitudinal direction to the displacement direction V of the extension module 4. The recesses 30 allow the outer wall 22 to bend so that it can adapt to the outer contour of the wall elements 15.

[0061] Figure 6c) shows a perspective view of Figure 6a). The flexible outer wall 22 has a dovetail guide 31, which is slidably connected to the dovetail slide 32. Two dovetail slides 32 each are connected to the side wall 7 of the base module 3, which is oriented transversely to the displacement direction V of the extension module 4, and to the side wall 12 of the extension module 4. This allows the flexible outer wall 22 to be moved when the wall elements 15 are transferred from the lowered to the raised position.

[0062] The flexible outer wall 22 has two parallel dovetail guides 31. As shown in Figure 6 c), these dovetail guides 31 also serve to guide the wall elements 15. The dovetail guides 31 run parallel to the displacement direction V of the extension module 4 and, in addition to the sliding connection with the side walls 7, 12 of the residential structure, ensure that the flexible outer wall 22 adapts to the outer contour of the wall elements 15.
