Camping vehicle

The invention relates to a camping vehicle (caravan, mobile home or piggyback attachment of a camping mobile) according to the preamble of claim 1.

Camping is the temporary life on holiday campsites understood in tents, caravans or campers.

The easiest way to camp is to stay in a tent. This offers insufficient protection against cold and rain and is therefore not very comfortable.

Another type of camping is possible with a camper van. A camper van is usually a minibus, whose usable space was converted into a combined living room, bedroom and kitchen. With the common camping vehicles If the usable space is too small for a travel group, for example a family, to stay comfortably. If

the usable space is enlarged by well-known prehistoric constructions and tent structures, are the same here Disadvantages as with pure tent constructions, d. H. bfi bad weather periods is the stay in the additionally created useful space uncomfortable, so that the residents are back in the. the interior of the vehicle is too small will withdraw. Another serious disadvantage of tent structures is that the The mobility that characterizes a camper van is lost if it is stuck by a tent extension or conversion is tied to one place. This means that the users are also stuck due to the mostly lack of alternative driving options tied to the campsite or the tent structure must be dismantled each time the camping mobile is removed.

Due to the tightness of the interior space of a camping mobiis, the living and seating area must usually be disadvantageous by extensive Conversions can be converted into sleeping arrangements.

Recently, campers are being offered, with a vehicle consisting of a chassis and a driver's cab Piggyback attachment (pick up) can be upgraded to a camper van. The piggyback attachment can be used at the campsite can be parked and the vehicle can be used for excursions, sightseeing trips, etc.

These piggyback campers are smaller on the base Passenger car built up, making the piggyback attachment is naturally very small and essentially only has minimal requirements for comfort and pleasant living can meet. Any enlargement of the living space is not possible, as regulations govern the maximum Overhangs on vehicles must be taken into account and overhangs that are too large lead to too great a shift in the center of gravity and thus lead to an unreasonable deterioration in driving characteristics.

The trend, especially for long-term campers, is towards spacious, comfortable caravans, which can be built with the help of a passenger car

is dragged to the desired destination. When parked there, the caravan offers protection against the effects of the weather Relatively well-protected dwelling, so-called winter camping is also possible with well-insulated designs, where ^ δ is still available without restriction in the case of passenger cars. The space available in a caravan is usually bigger than in a camper van. These advantages are offset by a number of disadvantages, which mainly consist of the large space requirements and the shapelessness of a caravan grow. For most caravan owners this is Parking in the unused time poses a significant problem. Usually you need expensive parking spaces or Garages can be rented. Further disadvantages arise during transport. A combination of passenger cars and one Caravan can be due to the great length, the high center of gravity of the caravan and the great air resistance due to the reduced driving characteristics only with effort and concentration at low speed can be moved. In addition, a lot of fuel is used. Still for camping purposes caravans with very large dimensions are offered, a separate living room and bedroom is only provided in exceptional cases, as otherwise both rooms would be too small. The living space has to be renovated every evening, such as lowering the table, Folding out benches, putting on mattresses, etc. can be converted into a bedroom. For one thing, this is time-consuming and complex and on the other hand it only allows a little individual holiday life, since all caravan residents, For example, adults and children have to go to bed at the same time.

To reduce the dimensions of a caravan when not in use and during transport, two solutions are known:
35

Folding caravans consist of a relatively low, tub-shaped Substructure with axle and wheels, in and on the

Folding walls and the roof are attached. For the transport this is due to the reduced air resistance and a lowering of the center of gravity of the caravan downwards, improved driving behavior and lower fuel consumption achieved. The storage of the folding caravan is simplified in some constructions by that it can be folded up sideways using a relatively small amount of space on a wall. When the folding caravan is to be used, the roof is raised and the hinges connected to the substructure Folding walls unfolded to standing height. The floor area remains the same, which means that there is less space in the It is not enlarged compared to the ordinary caravan. Furnishings such as wall cupboards etc., must be removed or reattached when the walls are folded down. Some are furnishings attached with elaborate hinge and scissor guide constructions, with the help of which you can fold the Move the walls towards the center of the caravan and lower them. As a result, a large part of the caravan space falls as Storage space for transport away. The construction is usually time-consuming and complicated and thus reduces the Mobility.

The so-called folding caravan is also a relatively low trailer Floor area is enlarged. A tent construction is then set up on these solid ground surfaces. The folding caravan thus serves essentially as a means of transport for a tent and its furnishings and as solid sub-floor. The disadvantages of the advantageously small dimensions of the folding caravan are the low level of protection against weather influences and the complex and time-consuming Construction and dismantling and therefore only a low level of mobility. It is also an embodiment of one Folding caravans known / where the cover areas for Enlargement of the floor area can be unfolded and then

Side walls made of solid material can be folded up. But here, too, the folding caravan essentially serves as a Transport trailer for the fixed wall parts. All furnishings must be completely dismantled or rebuilt will; Fixed living areas or bunks are missing.

The object of the invention is to create a camping vehicle, the floor space and living space in the The operating state compared to a transport state can be easily enlarged in the case of almost established areas.

This object is achieved with the characterizing features of claim 1.

According to claim 1, at least two, approximately horizontal standing or lying areas containing residential units should have a substantially horizontal rail guide with each other be connected. The rail guide can be in Lying across or lengthways. However, it has proven to be particularly expedient to move or pull one out Living area proven lengthways. The dimensions of the Camping vehicle can be advantageously reduced in size, while after moving the sliding unit of the living space can be advantageously enlarged during use.

A caravan can therefore be stored more easily; during transport it has a lower air resistance and a shorter length, which both improves handling and reduces fuel consumption. Can continue With the same transport dimensions as before, caravans with a much larger living space were created will. For example, it is possible to slide a fully furnished bedroom into another room, so that when using the fully furnished bedroom is simply extended, so that two divisible Rooms of sufficient size are available.

In the case of camper vans, the proposed construction allows the living area to be pushed together above the chassis so that with reasonable dimensions of the motorhome a vehicle with a good center of gravity, relatively small dimensions and without large protrusions is possible. This also means a good transport option here with good driving characteristics and few difficulties in parking and parking. For a This can be particularly advantageous for a camper because it is often used as an everyday vehicle throughout the year, at least as a second vehicle. The advantages of cuckoo attachments are accordingly.

By increasing the space available in the extended state, fixed sleeping areas can be created created so that the usual daily conversion from living to sleeping purposes (lowering the table, etc.) can be omitted. This also makes more individual living of a larger community possible, because no more all people at the same time, e.g. B. Adults and children need to go to bed.

According to claim 2 it is proposed that the guide rails on opposite sides of the substructure in a vertical To provide a clearance upwards to its floor surface (standing surface). The vertical distance should be like this be large so that the movable living area is at least above the seat height, if necessary above the working height (table, Kitchen worktop) comes to rest when pushed in. This ensures that in the central living area No or only minor modifications are required if the sliding unit (sleeping area with raised Lying areas) should be pushed into the central living area. So are neither in the sleeping area nor in the Living area requires major renovations, only the two areas have to face each other for transport be moved.

According to claim 3, it is useful in a caravan to provide two pull-out sleeping compartments, which leads to a considerable increase in space. It is the first time Possible with a caravan of reasonable dimensions, two separate bedrooms (e.g. for parents and children or two married couples). It should be emphasized here again that the sleeping compartments can remain fully set up during transport.

In claim 4 it is proposed to attach a kitchen block (gas oven, sink etc.1) to the movable EiiMieit. Thus, these parts can be moved together with the sliding unit and need when Move in no case to be dismantled. This design is particularly advantageous when the sliding Area with its lying surface above the seat height is pushed into the central area, so that bench seats etc. can be left in the central area without modification when pushing together. In connection with the next Folding structures stressed below can thus be achieved with a relatively low overall height.

For better guidance, support and a more stable stand are in claim 5 fold-out or extendable Proposed rail extensions that protrude beyond the substructure and during transport or for storage can be folded in or pushed in.

3ö The sliding unit can be in the form of a square telescopic tube be able to slide into the central unit. In claim 6 is a cheaper producible version reproduced. In this case, a displaceable unit should at least partially be an outer wall of the camping vehicle form collapsed state. When pulling apart, at least one opening is then created in the outer wall, which is opened by a folded, hung or

stretched wall made of solid or cloth-like material is closed * Such an embodiment can also be can be converted quickly and easily »

In claim 7, the camping vehicle is formed in the manner of that its height can also be reduced by folding walls. This training is especially for caravans provided with two opposing, displaceable units * With the features of claim 7 is thus a further reduction in the external dimensions and thus improved transport and simplified storage achieved. This requires a middle roof panel into which the sliding units overlap Roof panels are retractable.

If two opposing, displaceable units are provided, and these units or their displaceable units Floor panels cover the entire substructure in the transport state, the central roof panel has no immediate Connection to the substructure. When the two sliding units are extended, the central one must Therefore, the roof panel is held in its central position. In claim 8 is a very simple device in the Form of a cord cross indicated. One end of a cord is attached to the roof panel and the other end End connected to the substructure. This device has proven to be particularly advantageous in the case of designs that are described in the height can be reduced. There are of course other connecting elements, such as. B. striving, Cable guides etc. possible.

According to claim 9, the central roof panel should at least have a surface inclined in the pull-out direction of the pull-out units. This ensures that the Pushing out the sliding unit, the roof panel is raised = it becomes lower for transport Achieved structure that only after pushing out the

movable units achieved the desired headroom. In the case of a hinged version, the central one must be here The roof panel must not be pried up to full standing height before moving the sliding units. The final lifting of the roof panel to the desired height is only done by the push-out part.

With the fittings mentioned in claim lo with eccentric connections movable walls are held together in a stable manner, which improves the statics and seals the Wall connections facilitated.

According to claim 11, the displaceable unit is intended to be movable with the aid of a crank drive. With a corresponding The large gear ratio selected means that the sliding units can be moved without great effort possible. The crank drive can in a known manner with a cable and roller guide or with a rack and pinion gear work together. If there are several displaceable units, they can be synchronized with a crank be designed to be movable.

An exemplary embodiment of the invention with further features, details and advantages is shown on the basis of a drawing described in more detail.

In Fig. 1, a caravan 1 is shown, which essentially consists of a substructure 2 with wheels 3, 4, a trailer coupling 5, a roof part 6, two movable sleeping berths 7, 8 with folding walls 9, 10, and with folding walls 11 on substructure 2 consists. The roof part 6 contains an upper roof panel 12 which covers the substructure 2 with a ridge 13 transverse to the direction of travel and two longitudinally extendable side roof panels 14, 15, which under the central roof panel 12 are inserted. At the front and back of the caravan 1 are each a storage space 16 for gas, water etc., and a storage space 17 for luggage etc. can be seen. Bunks 7, 8 will be like this pushed out far (see Fig. 9) that the storage spaces 16, 17 are still covered. Further in Fig. 1 are the lower Part of an entrance door 18 and guide rail extensions 19, 20 folded onto the front and rear to see.

From the rear view of the caravan 1 according to FIG. 2 goes shows that the rear guide rail extension 20 consists of two folded parts 21, 22 with inclined struts 23, 24 consists,

In the plan view of the caravan 1 according to FIG. 3, the folded walls for the berths Ί, 8 and the substructure 2 are shown in dashed lines. The positions, folding directions and functions will become clear in detail in connection with the following figures and the description.

In Fig. 4, the roof part 6 is raised on the right side to set up the caravan 1 and with a Hinges on the front bunk 7 connected folding wall 25 supported. The folding wall 25 is at the Upper side connected to the inserted side roof panel 14.

Then the rear side of the roof part is also raised and through a hinged wall 26 on the rear Bunk 8 supports (see Fig. 5). To secure the central roof area against shifting, a Cord cross 46 attached in such a way that two ends are braced on the substructure 2 and two ends on the upper roof panel 12 are.

In Fig. 6, the side folding walls 27, 28 with windows 29, 30 are folded up on both sides. The side folding walls 27, 28 and the folding walls 25, 26 are firmly connected to one another with fittings, so that stable bunk areas result.

Then the lateral guide rail extensions 19, 20 in the direction of the longitudinal axis, as in Fig. 7 and 8 shown, folded. From the plan view of FIG. 8 it can be seen that for an improved

Lateral stabilization struts 31 to 34 from the substructure 2 to the guide rail extensions 19, 20 are provided are. A comparison of FIG. 3 with FIG. 8 clearly shows how those that have already been opened Walls 25, 26 and the four side walls 27, 28 in the closed state above the floor parts of the bunks 7, 8 lie.

With the few movements described so far, the caravan 1 can be pushed out to push out the two berths 7, 8 prepared.

In FIG. 9, the caravan 1 is already shown with the sleeping berths 7, 8 extended. The sideways movement happens synchronously with the aid of a crank 35 which is attached to a shaft (not shown) from the outside will. The crank 35 could be connected to a known rack or worm drive, which is in the Guide rail 36 could be attached to the substructure 2.

A simple form of a pulling and pushing device could consist in that a rope can be wound up on the shaft downstream of the crank 35 for each of the berths 7, 8 and is connected to the bottom of each bunk 7, at its front and back. When the berths 7, 8 are pushed out, the piece of rope directed towards the center of the caravan would be subjected to tension, while the other piece of rope would unwind to the outside of the berths 7, 8. When pushing together, however, the rope tensions would be reversed. With a suitable cable guide and deflection via rollers, this winding or unwinding process for both berths 7, 8 can take place simultaneously with a crankshaft. This enables the two berths 7, 8 to be extended simultaneously and synchronously. In the illustrated Aüsführungsbeispiel this 1st necessary because the central roof panel is inclined on both sides to the front and rear. When the berths 7, 8 are extended, the side roof panels 14, 15 are over the berths 7, 8

with pushed out of the roof part 6 and at the same time the central Roof panel 12 raised because of its longitudinal inclinations to the desired headroom. If the two berths 7, 8 are not are extended simultaneously and synchronously, there is a risk that the panels tilt in the sloping roof. That Cord cross 46 is there to the central roof panel 12 during the extension process in its central position keep.

From Fig. 9 it can be clearly seen that the substructure 2 is roughly trough-shaped and seating etc. can be attached in this trough (not shown) which are not touched by the pushing-out movement of the lower parts 37, 38 located higher up. This also means that the tub-like substructure 2 can be used as storage space during transport. The bunk 7 _R 8 are extended so far against a stop that they still remain in part over the casing 2 in the guide rail 36th The spaces remaining under the coverage area are partitioned off by walls and form the storage spaces 16, 17, which can also be used during the camping season. In addition, it can be seen that the lower parts 37, 38 of the bunk beds 7, 8 have the shape of flat boxes in which mattresses and bedding have plenty of space even when the bunk beds are folded down. In addition, the beds do not need to be changed either during assembly or during assembly in the bunk beds 7, 8. For good stability in the extended state, stable supports 39, 40 are required between the contact surface and the substructure. Additional supports could also be provided on the berths 7, 8.

By pushing out the berths 7, 8 openings are created in the side walls, which can be opened by folding up the middle folding walls 11 are closed on both sides. The wall 11 lying in the viewing direction also contains the upper part of the door cutout of the entrance door 18 (see

Fig. 10). The folding walls 11 also contain windows 41, 42.

In Fig. 11, the caravan 1 is already shown in the fully assembled state. In addition, those in German were added Berths 7, 8 lying compartment walls 43, 44 folded up, creating the central living area and the bunk beds 7, 8 are separated from each other. From Fig. 11 it can be clearly seen that the bunk 8 has larger dimensions is, d. H. the folding compartment wall 43 is attached further towards the center of the caravan than in the case of the bunk 7. This is due to the fact that the bunk 7 a kitchen block 45 with hotplate etc. is already connected to the living area at the correct working height and when pushing out the bunk 7 with this over the Storage space 16 is moved. In the storage space 16 are therefore appropriate for the kitchen operation Devices such as gas bottle, water container, etc. are stored. In the embodiment shown, a caravan 1 needs hence the kitchen block 45 neither needs to be lowered nor rebuilt.

In the perspective view of FIG. 12, the individual walls and areas are shown with the aid of the dashed lines clearly recognizable again. In the middle is the central living area at standing height with the substructure 2, the one on the side Guide rails 36, the entrance door 18, the central roof panel 12, the side hinged walls 11 and the Windows 41, 42. The rear bunk 8 contains the box-shaped lower part 38, the rear folding wall 26 the lateral folding walls 27 with windows 29, the Seitenda.cnplatte 15 and the compartment folding wall 43 with a door arch cutout.

The front, smaller bunk 7 also contains the box-shaped lower part 37, the front hinged wall 25, the side hinged walls 28 with windows 30, the side roof panel 14 and the folding wall 44 with a round

bow neckline. The kitchen block 45, which can be displaced with the bunk 7 above the storage space 16, can also be seen .

In summary, the individual steps for building the caravan 1 should be listed one after the other be: The collapsed caravan is towed to its place; the supports 39, 40 become unfolded the caravan 1 is unhooked; the roof part 6 is raised and formed by the hinged panels 25, 26; the side folding walls 27, 28 of the berths 7, 8 v / ground unfolded and connected to the hinged walls 25, 26; the string cross 46 is attached; the guide rail extensions 19, 20 are unfolded and locked; with the help of the removable crank 35 are the Berths 7, 8 extended; the middle folding walls 11 are folded up; the compartment folding walls 43, 44 are folded up. The handles described above are in feasible a few minutes, with the collapsed and pushed together caravan according to FIG. 1 of the Caravan according to FIG. 12 with an enormous amount of space is created. It should be emphasized again that on the interior of the caravan 1, neither in the living area nor in the bunk beds and remodeling work is required because the vertically offset standing and lying areas make the Caravan equipment does not need to be changed either during assembly or assembly.
