Description

[0001] The present invention relates to a motorhome or a caravan.

[0002] Nowadays, motorhomes are a widespread mobile option for leisure and holidays. A motorhome is understood to be a vehicle that, similar to a caravan, is equipped with an interior suitable for living. This includes cooking facilities, sleeping accommodations for at least two people, and washing facilities or a toilet. Depending on the size and features, these amenities can be comparable to an apartment or house and may even be suitable for more than two people. Motorhomes can also be called recreational vehicles. They constitute a distinct vehicle category.

[0003] Typically, a small van or its chassis serves as the base vehicle for a motorhome. These vehicles themselves have a maximum permissible weight of up to 3.5 tons and can therefore be driven in Germany with a Class B driver's license. However, if a small van chassis is used as the basis for a motorhome, the resulting vehicle usually has a maximum permissible weight exceeding 3.5 tons and thus requires a higher driver's license category. In Germany, for vehicles with a maximum permissible weight between 3.5 and 7.5 tons, a Class 3 or C1 license is required; above that, a Class C license is necessary. Only motorhomes with a maximum permissible weight of up to 3.5 tons can be driven in Germany with a Class B license, similar to a passenger car. Otherwise, driver's licenses corresponding to those for trucks are required, as mentioned previously.

[0004] A disadvantage regarding the operation and driving of motorhomes is that the standard Class B driving license, sufficient for passenger cars, only permits the operation of relatively light and therefore small, cramped, and uncomfortably equipped motorhomes, leading to corresponding limitations in their use. If users of a motorhome desire more space and comfort, a higher driving license class is required, at least in Germany.

[0005] A disadvantage of exceeding the permissible total weight of 3.5 tons is that it can restrict the motorhome's usability, as driving bans for such vehicles may apply to mountain passes, bridges, and city centers. Higher toll fees, ferry charges, and fines may also be levied for such vehicles. Furthermore, vehicles with a permissible total weight exceeding 3.5 tons must observe overtaking bans and maintain minimum distances from trucks.

[0006] A disadvantage of using a van chassis as the basis for a motorhome is that vans are typically designed for city driving. This means that a motorhome built on this chassis also requires paved roads, limiting or even preventing its use on unpaved roads, tracks, and off-road terrain. This leads to significant limitations in the motorhome's usability, especially if it is intended for use in nature or in remote areas.

[0007] Motorhomes are typically quite tall to provide full standing room inside. However, this height also limits their use, meaning that clearances for passing under bridges and similar structures must be observed. Furthermore, motorhomes are generally not permitted in parking garages.

[0008] Another disadvantage of motorhomes, due to their relatively high height, is that they have a relatively high drag coefficient when driving, which limits their speed and increases fuel consumption.

[0009] Another disadvantage of motorhomes, due to their relatively high height, is that they should not cross freestanding bridges during storms to avoid being caught by the wind and tipping over. Furthermore, their relatively high height makes them significantly more prone to swaying than other vehicles.

[0010] Motorhomes, for the reasons mentioned above, are also comparatively long, often exceeding 6 meters. This is disadvantageous because parking spaces are typically between 4.80 and 5.50 meters long, meaning they cannot be used by motorhomes longer than 6 meters. Exceeding the 6-meter length limit can also lead to additional costs, as ferries and campsites usually charge higher prices for motorhomes longer than 6 meters.

[0011] Similar considerations and disadvantages also apply to caravans, i.e., trailers for motor vehicles that are also equipped with living quarters. Motorhomes and caravans, also called campervans or camping trailers, differ primarily in that a motorhome has its own engine and can be moved using its own engine, whereas a caravan lacks such a drive and therefore must be towed by another vehicle to be moved.

[0012] DE 198 01 718 A1 describes a liftable roof hatch for motorhomes, primarily intended for small vehicles and as an alternative to stationary high roofs, folding or collapsible pop-up roofs, consisting of a one-piece, rigid, forward-opening hatch equipped with a projection and a stop approximately 5-20 cm wide at the lower edge, which, in the lowered position, encloses the upper part (excluding the cab window) of the stationary vehicle, and a hinged window attached to the front part of the roof hatch by hinges in such a way that, in the lowered position, it can be recessed into the projection of the hatch and, in the raised position, closes the front open side of the roof hatch, the stop being equipped with at least two guide cams on each side of the roof hatch.

[0013] DE 29 41 091 A1 describes a caravan variable in height and length with a transport box arranged on its chassis, which is designed as a living area base, wherein a one-piece living area upper section and a one-piece extension upper section can be accommodated in the living area base, and wherein the living area upper section together with the extension upper section can be raised vertically from the living area base and placed onto the living area base by means of support and connecting elements, wherein furthermore the extension upper section can be extended horizontally from the raised living area upper section by means of, for example, sliding rails or roller guides by means of, for example, sliding rails or roller guides and can be placed onto a two-piece extension lower section formed from the end parts of the transport box lid to form a closed living area cell.

[0014] The German patent DE 20 2023 000 252 U1 describes a mini camper top for use with light vehicles as a base for a campervan, comprising the following components: - A top box for the loading area of ​​a light vehicle, with dimensions matching the size of the base vehicle, from approximately 1.3 m wide, 1 m high and 1.8 m long - A bell-shaped pop-up roof extending over the entire box, which can be raised high enough to achieve standing height inside - A rear extension that can be extended as soon as the pop-up roof is raised, its height and width slightly less than the box itself, with a length approximately half the size of the box - A bed extending into the rear extension - Interior fittings suitable for the pop-up roof and extension, i.e., two-part sliding cabinets or a washroom, and a two-part door.

[0015] German patent DE 10140 272 A1 describes a motorhome produced by converting a standard small commercial vehicle by inserting a roof extension into a cut-out opening. The roof extension consists of a prefabricated fiberglass shell with side windows. The fiberglass shell is raised and lowered as needed using four hydraulic jacks.

[0016] One object of the present invention is to provide a motorhome or caravan of the type described above, such that, despite a comparatively low permissible total weight, relatively short length, relatively short width, and / or relatively low height, the greatest possible comfort and / or the most extensive possible range of uses for the occupants can be offered. In particular, the aim is to create a highly comfortable, off-road capable motorhome with a permissible total weight of less than 3.5 t and a length of less than 6 m. In any case, this should preferably be implemented in a way that is as simple, cost-effective, compact, intuitive to use, and / or durable as possible. At the very least, an alternative to known motorhomes and caravans should be created.

[0017] The problem is solved according to the invention by a motorhome or a caravan with the features of claim 1. Advantageous further developments are described in the dependent claims.

[0018] The present invention thus relates to a motorhome or caravan with a living cabin and interior furnishings designed for living. The living cabin is the part of the motorhome or caravan that is mounted on a chassis and at least substantially encloses an interior space. The interior space, serving as living quarters, contains furnishings of the type used in motorhomes and caravans to enable people to use the motorhome or caravan for living purposes, i.e., sleeping, washing or showering, eating, cooking, sitting, and the like.

[0019] The living cabin has at least one element which is designed to be extended when the motorhome or caravan is stationary in order to increase the interior space of the living cabin, and to be retracted when the motorhome or caravan is in motion in order to reduce the dimensions of the living cabin.

[0020] Stationary operation refers to the state of a motorhome or caravan when it is stationary for residential use, without any movement or driving. For this purpose, the caravan can be uncoupled from the towing vehicle and held securely in position using a brake, possibly with wheel chocks. In stationary operation, the motorhome's engine may be switched off and the parking brake engaged. Utility connections such as for electricity, fresh water, and wastewater may also be connected to the motorhome or caravan.

[0021] Unlike when stationary, when driving, the motorhome or caravan is capable of being moved or driven in traffic. This means that people can leave the caravan and it can be attached to a towing vehicle. The motorhome can be ready to drive, or the engine can be running. However, during driving, there are no connections to utilities or other supplies.

[0022] The present invention is based on the understanding that the disadvantages of motorhomes and, to some extent, caravans described above can be at least partially overcome or reduced by using at least one extendable / retractable element to adapt the interior volume of the living cabin to the operating condition of the motorhome or caravan. This can increase usability and comfort for the occupants when stationary. At the same time, the external dimensions can be kept small when driving. This can also reduce the weight of the motorhome or caravan. Extending and retracting the element can be achieved by means of a drive, preferably electric, pneumatic, or hydraulic, so that a compressor, which is already present, can preferably be used for this purpose.

[0023] According to the invention, a retractable element of the living cabin is a pop-up roof, which is designed to be raised relative to an outer wall of the living cabin along the vertical axis by means of a lifting mechanism in stationary operation in order to increase the interior space of the living cabin, and to be lowered relative to the outer wall of the living cabin along the vertical axis in driving operation in order to reduce the height of the living cabin.

[0024] Thus, according to the invention, the volume of the interior of the living cabin can be increased vertically, i.e., along the vertical axis, when stationary, in order to enable users to stand upright. This can significantly improve user comfort. Reducing the height of the motorhome or caravan while driving reduces swaying. It also reduces drag and the lateral surface area exposed to wind.

[0025] The lifting mechanism can be any suitable driven kinematic system. In particular, scissor kinematics and linear lifting mechanisms can be used, the latter being described in more detail below as the preferred lifting mechanism.

[0026] According to one aspect of the invention, the lifting mechanism has at least one linear drive, wherein a stator of the linear drive is fixedly arranged on the living cabin and is configured to move an output of the linear drive translationally along the vertical axis, wherein the output is movably connected to a linear guide of the lifting mechanism along the longitudinal axis, facing away from the stator, wherein the linear guide of the lifting mechanism is fixedly arranged on the pop-up roof.

[0027] In other words, the linear actuator can move an output, such as a piston, linearly up and down along the vertical axis, with the output being received, held, and moved by the stator of the linear actuator. An electric motor or a pneumatic or hydraulic pressure cylinder can be used as the drive principle, preferably to utilize the electrical supply, compressed air, or hydraulic pressure of the motorhome or caravan for this purpose. In any case, the pop-up roof can have a linear guide running along its longitudinal axis, which movably receives the end of the output facing away from the stator and thus protruding from it.

[0028] Thus, to raise the pop-up roof, the output shaft can be moved or pushed upwards out of the stator along the vertical axis. The end of the output shaft connected to the linear guide of the pop-up roof can then be moved along the linear guide relative to the pop-up roof. This allows the purely translational movement of the linear drive's output shaft along the vertical axis to cause a movement of the pop-up roof, in which the roof is both raised along the vertical axis and moved or shifted along its longitudinal axis. This can enable the pop-up roof to be raised using a lifting mechanism if the pop-up roof is simultaneously pivotally connected to the outer wall of the living cabin, so that a purely translational movement of the pop-up roof is not possible, as will be described in more detail below.

[0029] Preferably using a pair of linear actuators spaced apart along the transverse axis can prevent laterally acting mechanical moments that could lead to tilting of the lifting mechanism elements. This can also ensure smoother movement. Furthermore, the linear actuators can be made weaker and therefore smaller or more compact, which can reduce the width of the motorhome or caravan.

[0030] Preferably, integrating the stator of the linear drive into a side wall of the living cabin can at least visually conceal the stator of the linear drive from people and thus improve the visual design.

[0031] According to a further aspect of the invention, a fabric cover is arranged between the outer wall and the pop-up roof, which is designed to be stretched along the vertical axis when the motorhome or caravan is stationary in order to smoothly close the gap between the outer wall and the pop-up roof of the living cabin, and to project into the interior of the living cabin when the motorhome or caravan is in motion in order to release the gap between the outer wall and the pop-up roof of the living cabin.

[0032] This aspect of the invention is based on the understanding that when using a pop-up roof, a gap is created between the upper edge of the outer wall and the lower edge of the pop-up roof, causing the living cabin to leak. This allows wind, rain, air, and the like to penetrate the interior of the living cabin, and allows air to escape from the interior to the outside. Therefore, according to the invention, this gap between the outer wall and the pop-up roof of the living cabin is permanently sealed by a fabric cover, similar to the material of a convertible's retractable roof, so that even when the pop-up roof is raised, the interior of the living cabin remains weatherproof. The gap between the rigid outer wall and the rigid pop-up roof is thus always closed.permanently sealed by a fabric cover made of a flexible, windproof and waterproof material, so that the interior is weatherproof both when driving and when stationary, as well as during the movements of the pop-up roof between driving and stationary operation.

[0033] For this purpose, the edges of the fabric cover can be firmly attached to both the upper edge of the outer wall and the lower edge of the pop-up roof. The fabric cover can also be sufficiently flexible to fold down when the pop-up roof is lowered. Suitable guide mechanisms, similar to those used in convertible roofs, ensure that the fabric cover moves into the interior of the living area, allowing the upper edge of the outer wall and the lower edge of the pop-up roof to meet when the roof is fully retracted or lowered.

[0034] Providing the fabric cover preferably with at least one window element allows occupants to look out through the window element and allows sunlight to enter the living cabin when the pop-up roof is extended, thus increasing the brightness inside and improving the ambiance. Flexible transparent films or rigid transparent panes, preferably made of plastic, similar to those used in convertible roofs, can be used for this purpose.

[0035] According to a further aspect of the invention, the motorhome or caravan also has a plurality of wall parts which are designed to be arranged flatly inside the space between the outer wall and the pop-up roof when the motorhome or caravan is stationary, and to be removed into the interior of the living cabin when the motorhome or caravan is in motion in order to release the space between the outer wall and the pop-up roof of the living cabin.

[0036] These wall elements can provide additional reinforcement to the taut fabric covering from the inside. This can increase the stability of the seal between the outer wall and the pop-up roof of the living cabin. The wall elements, for example made of expanded polystyrene or extruded polystyrene, can also be thermally insulating, thus improving the thermal insulation of the fabric covering. In any case, the wall elements can also improve sound insulation.

[0037] The wall elements can be designed as separate, essentially loose components, allowing users to move or carry them manually and insert them into the space between the outer wall and the pop-up roof of the living cabin from the inside, against the fabric covering. This can increase the flexibility of the interior design, as the wall elements can be stored as needed when not in use.

[0038] Providing the wall elements preferably as hinged walls, which are either pivotally or hingedly arranged at the upper edge of the outer wall or at the lower edge of the pop-up roof, can make it easier and faster for the occupants to position the wall elements from the inside against the fabric covering in the space between the outer wall and the pop-up roof of the living cabin. In particular, it can relieve the occupants of the task of assigning the loose wall elements to the correct position in the space between the outer wall and the pop-up roof of the living cabin.

[0039] Preferably providing the wall elements with at least one window recess corresponding to a window element of the fabric covering can prevent a window element of the fabric covering from being covered by a wall element.

[0040] According to the invention, the pop-up roof comprises at least: a first roof element which is pivotably connected to the outer wall by means of at least one pivoting element along the transverse axis, and a second roof element which is pivotably connected to the first roof element by means of at least one pivoting element along the transverse axis.

[0041] In this way, a pop-up roof can be realized which, due to the two pivoting elements that each run along the transverse axis, is relatively stably connected to the outer wall and yet pivots freely relative to the outer wall. This allows the pop-up roof to be extended and retracted relative to the outer wall, for example, by means of the previously described lifting mechanism, which, due to the translational movement of the linear drive's output along the longitudinal axis, enables the translational movement of the second roof element. In other words, the first roof element, which pivotally connects the second roof element and the outer wall, can, in addition to its function as part of the pop-up roof, also act as a kinematic mechanism.

[0042] In any case, with the pop-up roof extended, the second roof element can be horizontally aligned so that the desired height, especially the standing height for the users, can be achieved everywhere, while at the same time keeping the height of the living cabin low during driving.

[0043] The stability of the connection between the outer wall and the first roof element and / or between the first roof element and the second roof element can be further improved by using appropriately stable or elongated pivoting means, such as hinges, preferably a film hinge and / or a rod hinge.

[0044] In any case, the first roof element can be positioned at a front edge of the outer wall, i.e., facing the front of the motorhome or caravan in the direction of travel, or at a rear edge of the outer wall, i.e., facing away from the front of the motorhome or caravan in the direction of travel. This can increase the design flexibility.

[0045] Ideally, one or both roof elements should be equipped with at least one window element, allowing occupants, especially those lying down, a view to the outside. This also allows light to enter the interior of the living cabin from above, increasing the brightness and improving the ambiance.

[0046] Preferably installing solar cells on one or both roof elements allows the roof surface to be used for generating electricity. Installing solar cells on at least the second roof element can improve their efficiency due to their orientation towards the sun. Simultaneously, these solar cells can block sunlight from reaching the second roof element, thus reducing the heating of the living cabin's interior, which is comparable to a roof in the Sahara.

[0047] According to a further aspect of the invention, a retractable element of the living cabin is at least one side element which is designed to be extended in stationary operation through a corresponding side opening of an outer wall of the living cabin opposite the outer wall of the living cabin along the transverse axis in order to enlarge the interior of the living cabin and / or to allow access to a storage space of the side element, and to be retracted in driving operation through the corresponding side opening of the outer wall of the living cabin opposite the outer wall of the living cabin along the transverse axis in order to reduce the width of the living cabin.

[0048] This can also be a way to increase the usable interior volume of the living cabin along the transverse axis when stationary, while simultaneously keeping the lateral dimensions of the motorhome or caravan to a minimum when driving. The interior volume of the side element, which can also be called a slide-out, can be used as storage space for items such as dishes, cooking utensils, supplies, and the like, accessible from inside. Alternatively, the side element can provide storage space that is only accessible from the outside when the slide-out is extended. Or, the interior volume of the side element can remain empty and open to the inside, providing a footwell for a person while sleeping, thus improving sleeping comfort by creating a longer sleeping surface.

[0049] Preferably also equipping a side element with solar cells can also enable the generation of electrical energy at this location.

[0050] According to a further aspect of the invention, a retractable element of the living cabin is at least a rear element which is designed to be extended in stationary operation through a corresponding rear opening of an outer wall of the living cabin opposite the outer wall of the living cabin along the longitudinal axis in order to enlarge the interior of the living cabin and / or to enable access to a storage space of the rear element, and to be retracted in driving operation through the corresponding rear opening of the outer wall of the living cabin opposite the outer wall of the living cabin along the longitudinal axis in order to reduce the length of the living cabin.

[0051] In this way, the properties and advantages previously described with regard to the side element can also be implemented and used by means of a rear element, as previously described.

[0052] Preferably also equipping a rear element with solar cells can also enable the generation of electrical energy at this location.

[0053] According to a further aspect of the invention, the motorhome or caravan has at least one kitchen element and at least one first mattress, which is designed to be arranged along the vertical axis above the kitchen element when the motorhome or caravan is stationary, in order to free up the kitchen element, or to be placed on the kitchen element to be used, and when the motorhome or caravan is in motion, to be placed on the kitchen element to reduce the height of the living cabin.

[0054] This means that the area above the kitchen unit or kitchenette can also be used for sleeping when the kitchen unit is not in use. This can further increase the usability of the living cabin or further reduce the space required for sleeping. Raising and lowering the mattress can also be done electrically, pneumatically, or hydraulically, preferably pneumatically.

[0055] According to a further aspect of the invention, the motorhome or caravan has at least one seating element which is designed to be used for sitting when the motorhome or caravan is stationary, wherein the seating element is further designed to be used as a step-through element to reach the first mattress when the motorhome or caravan is stationary, when the first mattress is placed along the vertical axis on the kitchen element.

[0056] This can enable or facilitate a person to reach the first mattress without the need for an additional staircase or similar structure, as the seating element can be used not only for sitting but also as a step to reach the first mattress. This can further increase the usability of the living cabin and / or further reduce the space required for it.

[0057] According to a further aspect of the invention, the motorhome or caravan has at least one pair of seating elements opposite each other along the transverse axis and a table element arranged between them which is height-adjustable along the vertical axis, wherein the height-adjustable table element is designed to be raised along the vertical axis relative to the seating elements when the motorhome or caravan is stationary, in order to use the seating elements for sitting at the height-adjustable table element, and to be lowered along the vertical axis relative to the seating elements to their height when the motorhome or caravan is in motion, in order to use the seating elements and the height-adjustable table element as a lying surface.

[0058] This allows the seating or dining area to also be used for sleeping. This can further increase the usability of the living cabin or further reduce the space required for this purpose.

[0059] Designing the seating elements preferably as benches can increase their stability. It can also increase the usable surface area of ​​the seating elements for both functions.

[0060] According to a further aspect of the invention, the motorhome or caravan has at least one door for closing and releasing a door opening in an outer wall of the living cabin and an entrance area in the interior of the living cabin, which is arranged directly in front of the door, wherein the entrance area has a shower device and a water drain, so that the entrance area is designed to also be used as a shower area.

[0061] This aspect of the invention is based on the understanding that the entrance area of ​​a motorhome or caravan is currently used solely for entering and exiting the living area. When people are inside the living area, the entrance area can be considered unused space. Therefore, according to the invention, a shower can be created precisely in the entrance area, which typically has standing height, without having to use or waste any other area of ​​the living area. This can further increase the usability of the living area and / or further reduce the space required.

[0062] According to another aspect of the invention, the motorhome or caravan has a carrier vehicle which receives the living cabin as a structure either permanently connected, preferably by means of a 3-point mounting, or separably.

[0063] Thus, in the case of a motorhome, the present invention can be implemented by placing a living cabin on a carrier vehicle as described above.

[0064] This can be done with a permanent connection, so that the camper unit is fixed in place and can only be removed from the base vehicle by destructive means or with considerable effort, similar to the assembly of the motorhome itself; in other words, it is not intended to be removed from the base vehicle. This can increase the stability of the connection between the camper unit and the base vehicle.

[0065] Alternatively, this can also be achieved by designing the living cabin and the carrier vehicle to be separable via a suitable mechanical connection and, if necessary, electrical, pneumatic, and / or hydraulic contacts or connections. This allows for greater flexibility in using the carrier vehicle for other purposes with different attachments. This can be considered a modular concept. In this case, the connection between the living cabin and the carrier vehicle is designed to be as simple and quick to disconnect and reconnect as possible.

[0066] In any case, the carrier vehicle should preferably be designed for off-road use, for example as an SUV, pickup truck, or similar. This can also enable the motorhome to be used off-road, which can increase the range of accessible locations.

[0067] The rigid connection of the living cabin as a superstructure and the carrier vehicle or its chassis, preferably achieved by means of a 3-point mounting system, can prevent relative movement between the living cabin and the carrier vehicle, or at least ensure this as reliably as possible. This allows the living cabin and the carrier vehicle or its chassis to always remain aligned in the same direction.

[0068] According to a further aspect of the invention, a driver's seat and / or a passenger seat of the carrier vehicle is / are designed to be moved forward along the longitudinal axis into a driver's cab of the carrier vehicle when the motorhome is stationary, preferably folded down, wherein the motorhome furthermore has at least one first kitchen element which is arranged and designed in the living cabin, and which, when the motorhome is stationary, is moved into the area of ​​the driver's cab of the carrier vehicle that is freed up by the driver's seat and / or passenger seat of the carrier vehicle, which is moved away from there, preferably folded down, preferably pivoted about the vertical axis to utilize the first kitchen element, and, when the motorhome is in motion, is moved or pivoted into the living cabin so that the driver's seat and / or passenger seat areor the passenger seat of the carrier vehicle is moved within the driver's cab of the carrier vehicle towards the living cabin, preferably folded down, and can be used.

[0069] Thus, according to the invention, in a motorhome, it is possible to create an area or volume in the driver's cab of the vehicle into which the first kitchen unit can be moved and used by moving or folding forward the driver's seat and / or passenger seat. Since the driver's seat and / or passenger seat are not used when the vehicle is stationary, they can also be moved or folded away to accommodate the first kitchen unit in the driver's cab, thereby requiring less or no space inside the living area. This can further increase the usability of the living area and / or further reduce the space required for it.

[0070] Providing the first kitchen unit with a swivel function, particularly around the vertical axis, can increase the stability of its connection to the living cabin. This can also simplify the approval process for this feature of the living cabin.

[0071] According to another aspect of the invention, the living cabin and the driver's cab of the carrier vehicle are connected, allowing a person to move back and forth between the living cabin and the driver's cab of the carrier vehicle. This makes it possible to move between the living cabin and the driver's cab of the carrier vehicle without leaving the motorhome. This can protect the occupants from the elements, wild animals, and the like.

[0072] In the case of a movable or swiveling first kitchen unit, it may be necessary, at least to make the driver's cab accessible from inside the living area, to move or swivel the first kitchen unit into the living area and to move or fold back the driver's seat and / or the passenger seat of the vehicle. However, this can be done in this sequence from inside the living area. Thus, access to the driver's cab is possible in this case without leaving the motorhome.

Fig. 5 shows the representation of the Fig. 4 perspective from oblique rear top right further without side elements 20d and rear element 20g. Fig. 6 shows the upper part of the representation of the Fig. 4. Perspective view from a slanted rear right with partially shown wall sections 24.

[0076] The present invention is considered using the example of a motorhome 1, 2. The motorhome 1, 2 in each case has a carrier vehicle 1, the chassis 10 of which is used to support a living cabin 2, which can also be referred to as the body 2 or as the motorhome body 2 and will be described in more detail below according to two exemplary embodiments.

[0077] The carrier vehicle 1 can drive or move under its own power on a surface (not shown) on its four wheels 11, which are mounted on the chassis 10. The carrier vehicle 1 is designed for off-road use, as an SUV or similar vehicle is used as the carrier vehicle 1, so that the motorhome 1, 2 based on it can also be used off-road.

[0078] The drive unit or motor (not shown) of the carrier vehicle 1 is located in the engine compartment (not shown) beneath a hood 12 in the front section of the carrier vehicle 1. A driver's cab 13 extends rearward along the longitudinal axis X from the engine compartment or hood 12. In the cab, viewed in the direction of travel, a driver's seat 18 is located on the left and a passenger seat 19 on the right. The driver's seat 18 can be accessed through a driver's door 14 and the passenger seat 19 through a passenger door 15, each by a person 3 as user 3.

[0079] A trailer coupling 16 is provided at the rear end of the carrier vehicle 1 along the longitudinal axis X. A spare wheel 17 is removablely mounted in a spare wheel holder 20j on the left rear side of the living cabin 2 in an outer wall 20 of the living cabin 2.

[0080] The living cabin 2 is fixed and permanently, i.e., not detachable or removable, mounted on the chassis 10 of the carrier vehicle 1. The living cabin 2 is formed at least substantially below, to the rear, and to both sides by the aforementioned outer wall 20, which substantially encloses an interior space (not designated) or the interior of the living cabin 2.

[0081] On the right side of the outer wall 20, immediately behind the passenger door 15, a door opening 20a is provided in the outer wall 20, which can be closed by means of a pivoting door 20b. Through the open door 20b or through the unlocked door opening 20a, persons 3 can enter the interior of the living cabin 2 almost upright and first reach an entrance area 25, cf. Fig. 11, which, by means of a shower fitting provided there (not shown) and a water drain (not shown) in the floor, can also be used as a space-saving shower area 25. A fold-out dry toilet (not shown) can also be provided there.

[0082] Along the longitudinal axis X, a right side element 20d adjoins the door 20b on the right side. This element can be pneumatically extended and retracted through a side element opening 20c along the transverse axis Y using compressed air from a compressor (not shown) of the motorhome 1, 2, in order to enlarge the interior of the living cabin 2. A mirror-symmetrical left side element 20d is provided on the left side, i.e., on the driver's side. Both side elements 20d have a storage compartment (not shown) which is always accessible from the inside and can hold dishes, cooking utensils, supplies, and the like. Both side elements 20d have solar cells 20e on their upper surfaces to generate electrical energy.

[0083] Similarly, a rear element 20g is provided at the rear of the living cabin 2, which can be pneumatically extended and retracted along the longitudinal axis X through a rear element opening 20f. The rear element 20g also features solar cells 20i on its upper surface. The rear element 20g also offers storage space 20h, which, however, is only accessible from the outside when extended, in order to store items such as chairs and the like for use outside the living cabin 2.

[0084] The outer wall 20 terminates along the vertical axis Z upwards with a circumferential edge (not labelled), which runs essentially in the horizontal plane X, Y. This edge can also be referred to as a border. A pop-up roof 21 with a corresponding edge (not labelled) rests on the edge of the outer wall 20. According to the first embodiment, the pop-up roof 21 has a first roof element 21a with a window element 21b. The first roof element 21a is connected to the outer wall 20 by means of a pivot element 21c in the form of a film hinge 21c along the rear edge or rear border of the outer wall 20 along the transverse axis Y, so that the first roof element 21a can be pivoted about the transverse axis Y relative to the outer wall 20.

[0085] The pop-up roof 21 further comprises a second roof element 21d as the main roof 21d, which also has a window element 21e in the front area, i.e., near the engine hood 12, to allow reclining persons 3 to look directly upwards. The second roof element 21d is also pivotally connected to the edge (not labeled) of the first roof element 21a, which faces away from the film hinge 21c, by means of a pivot element 21f in the form of a rod hinge 21f. The second roof element 21d may have solar cells 21g, cf. Fig. 12 and Fig. 14 without window element 21e, which can also be set up, cf. Fig. 14, to improve its orientation to the sun and thereby act as a Sahara roof.

[0086] A lifting mechanism 22 is provided for extending and retracting the pop-up roof 21. This mechanism comprises a pair of linear actuators 22a, 22b, which are arranged opposite each other along the transverse axis Y directly next to the extendable / retractable side elements 20d, or between the right side element 20d and the door 20b or its door opening 20a within the outer wall 20. A stator 22a of each linear actuator 22a, 22b is fixed in place and connected to the compressor to pneumatically operate the linear actuators 22a, 22b. Using the compressed air from the compressor, an output 22b, in the form of a piston 22b, can be extended linearly along the vertical axis Z from the respective stator 22a and retracted again by releasing the air pressure via gravity.

[0087] In order to transform the purely translational movement of the outputs 22b along the vertical axis Z into the pivoting movement of the two roof elements 21a, 21d, the second roof element 21d has a linear guide 22c in the form of a rail 22c, which extends along the longitudinal axis X at the lateral edge (not labeled) of the second roof element 21d. There, the second roof element 21d is translationally connected to the end of the piston 22b facing away from the stator 22a, so that when the pistons 22b extend linearly along the vertical axis Z, the second roof element 22d is simultaneously raised along the vertical axis Z and moved backwards along the longitudinal axis X.As a result, the second roof element 21d lifts the first roof element 21a by pivoting due to the hinge-like coupling, which simultaneously pivots the first roof element 21a upwards due to the hinge-like coupling with the rear edge of the outer wall 20, see in particular . Fig. 3 and Fig. 4. This movement ends with a horizontally oriented second roof element 21d, which provides the persons 3 with a constant and sufficient standing height in the essential areas of the interior of the living cabin 2, see in particular Fig. 4.

[0088] In order to close a gap or space (not specified) between the upper edge of the outer wall 20 and the lower edge of the two roof elements 21a, 21d or the pop-up roof 21, a fabric cover 23 comparable to the fabric of convertible roofs is provided there, which is cut accordingly and fixedly attached at the edges, cf. for example Fig. 4, Fig. 5 to Fig. Figure 6 shows the process in sections. When the pop-up roof 21 is raised, the fabric cover 23 is stretched. When the pop-up roof 21 is retracted, the fabric cover 23 falls or folds into the interior of the living cabin 2. By means of the fabric cover 23, the interior of the living cabin 2 is completely separated from the environment, so that wind, rain and the like are always kept out of the interior of the living cabin 2, and heat is retained inside the living cabin 2.

[0089] To further improve the stability, thermal insulation, and sound insulation of this space between the upper edge of the outer wall 20 and the lower edge of the pop-up roof 21, several wall sections 24 are provided as folding walls 24, which can then be folded up or down by persons 3 when the pop-up roof 21 is extended and the fabric cover 23 is taut, cf. Fig. 6. For this purpose, the folding walls 24 can be made of expanded polystyrene or extruded polystyrene and be sheathed. The folding walls 24 can be pivotally attached to the inner sides (not labeled) of the outer wall 20 or the pop-up roof 21 by means of a hinge (not shown).

[0090] In order to allow persons 3 inside the living cabin 2 to see outside and to allow more sunlight into the interior of the living cabin 2, the fabric cover has window elements (not shown) and the folding walls 24 have correspondingly arranged window recesses 24a, cf. Fig. 7 and Fig. 8.

[0091] Fig. Figure 7 shows a side view of the motorhome 1, 2 according to a second embodiment from the right with the pop-up roof 21 extended and wall parts 24 partially shown. Fig. Figure 8 shows a perspective view of the Fig. 7 from the diagonal rear top right with all wall parts 24.

[0092] According to the second embodiment, the first roof element 21a is arranged at the front along the longitudinal axis X, so that the corresponding film hinge 21c runs along the transverse axis Y at the front edge of the outer wall 20 above the driver's cab 13. In this case as well, the first roof element 21a has a window element 21b to allow reclining persons 3 to see upwards and now also forwards. The window element 21e of the second roof element 21d is arranged in the rear area to illuminate the interior of the living cabin 2 from above with sunlight in the seating area, as will be described in more detail below.

[0093] Fig. 9 shows the representation of the Fig. 7 from above and without the pop-up roof 21, fabric cover 23 and wall parts 24 shown. Fig. 10 shows the representation of the Fig. 9th from the diagonal front top left. Fig. 11 shows the representation of the Fig. 9 from the top. Fig. Figure 13 shows a representation of the front area of ​​the Fig. 9 with mattresses 29a, 29b.

[0094] Based on the depictions of the Fig. 9, Fig. 10 to Fig. Section 11 now examines a kitchen unit 26 with a first kitchen element 26a, which includes a refrigerator 26a and a sink 26a, and a second kitchen element 26b, which includes a cooktop 26b and an oven 26b. The first kitchen element 26a is pivotable about the vertical axis Z on the second, fixed kitchen element 26b. The driver's seat 18 and the passenger seat 19 are also designed to fold forward along the longitudinal axis X, so that when not in use, they can be folded forward to free up the rear area of ​​the driver's cab 13. The first kitchen element 26a can then be pivoted into this area of ​​the driver's cab 13 for use without restricting the interior space of the living cabin 2.

[0095] If at least the driver's seat 18 is to be used again, the first kitchen unit 26a can be swung to the side again, and the driver's seat 18 can be folded back and occupied in order to drive the motorhome 1, 2. It is not necessary to leave the motorhome 1, 2 for this purpose.

[0096] The area above the two kitchen units 26a, 26b can be used for sleeping if the kitchen unit 26 is not in use. For this purpose, two mattresses 29a, 29b can be provided, extending along the longitudinal axis X and arranged side by side along the transverse axis Y. Both mattresses 29a, 29b can be designed to fold approximately in the middle to adapt to the contour of the extended pop-up roof 21 and thus be folded up to save space (see figure). Fig. 13, which can also be done pneumatically. For the right mattress 29b, a fold-out or extendable support surface (not shown) can be provided in the entrance area 25 to support the second mattress 29b from below, similar to the second kitchen element 26b.

[0097] Both mattresses 29a, 29b can be accessed and exited relatively easily via a seating element 27 arranged laterally in the rear area of ​​the living cabin 20 in the form of a bench 27 running along the longitudinal axis X, serving as a step or as an aid for getting in and out.

[0098] The two benches 27, together with a height-adjustable table element 28, which is arranged centrally between the two benches 27 along the transverse axis Y, can be used for sitting, eating, and the like. The table 28 can also be lowered to the height of the benches 27 along the vertical axis Z when the persons 3 are not on them, in order to create a flat surface in the horizontal X, Y, which can also be used for sleeping with mattresses (not shown), cf. Fig. 12.

[0099] When the motorhome 1, 2 is used in driving mode, i.e., when the motorhome 1, 2 is being driven or can be driven, the side elements 20d, the rear element 20g, and the pop-up roof 21 are retracted to minimize the external dimensions of the motorhome 1, 2. The height-adjustable table 28 must be lowered to the height of the bench seats 27 to make room for the retracted rear element 20g. The first kitchen unit 26a must also be swung towards the second kitchen unit 26b and secured, and the driver's seat 18 and the passenger seat 19 must be folded back. In this state, the motorhome 1, 2 is ready to drive. The interior of the living cabin 20 is almost completely filled by the movable elements, which are now retracted or swung in place.

[0100] When the motorhome 1, 2 is parked and moved into stationary mode to utilize the interior of the living cabin 20, the side elements 20d, the rear element 20g, and the pop-up roof 21 are extended. The driver's seat 18 and the passenger seat 19 are also folded forward, and the first kitchen unit 26a is swung into the driver's cabin 13. Furthermore, the height-adjustable table 28 is raised sufficiently to allow seating at the table 28.

[0101] In this way, according to the invention, a comparatively comfortable off-road motorhome 1, 2 with a comparatively low permissible total weight of less than 3.5 t can be created, which, when in operation, has a comparatively short length of less than 6.00 m, a comparatively short width of at most 2.10 m and a comparatively short height of at most 2.25 m. This allows the motorhome 1, 2 according to the invention to be arranged within an ISO container and thus also transported by ship.
