This measure offers the possibility of narrow furniture not only along the outer walls of the half-shells to arrange, between which there is a corridor for the caravan with those in the inner position Half-shell remains, but larger furniture groups can be created that are extend over the entire width of the liaumes enclosed by the two half-shells and when they move apart the half-shells are not separated, but continue to form a unit. As a result, a better use of space is achieved and it is when the half-shells move apart not only a central aisle is widened, but other areas become free that are attached to wall parts the opposite half-shell and therefore do not have to remain free as a corridor, but used in other ways, for example to build beds or the like. Can be used. In this regard, it is particularly useful if the furniture group arranged in one of the half-shells, which extends to close to the outer wall of the other half-shell, one to the direction of movement parallel viand adjoining a half-shell. It is then also possible to use furniture parts on both half-ovals to attach, which interlock telescopically in the inner position of the half-shells. That would be it is possible, for example, to accommodate a kitchen facility in one half-shell, from which the

Extending the half-shells, a worktop that adjoins the kitchen cabinet on the side is extendable.

In a preferred embodiment of the invention the furniture group is a seating group. It is particularly advantageous that for the seating group the entire width of the two in their inner position Half-shell enclosed space is available, so that this seating group for a larger number of

', People can be set up, and that this seat

group is not torn when extending the half-shells to the outer position · Such a seating group can be particularly advantageous from a U-shaped bench, the cross-section of which forms the U-shape Part of the wall that is parallel to the direction of movement is adjacent to one half-shell, and one between the Legs of the U-shaped bench arranged table consists. Such a seating group not only offers enough space for a larger number of people, rather can also be used as a sleeping area if the caravan is used by a large number of people should be inhabited whatever its size

C) , or the side panels in special cases

should not or cannot be extended. For this purpose, the table top can then be level the seat surface of the seats can be lowered and in the lowered position Connect the position tightly to the seat so that the seat and the table surface come together an essentially flat and essentially rectangular support surface which can be used for building a bed form.

7601151 11/17/77

In a "preferred form of implementation of the invention" there is a bed box attached to the other half-shell, which is accessible in the outer position of the half-shells and at the same time the support for a bed frame, under a bench attached to one of the calf schools and arranged parallel to the direction of movement of the half-shells forms. In this way, the barely occupied by the bench is used as a stowage room without the bench itself having to have a flap that may be difficult to access and which can be opened, and the beiia extend the half-shells freely into the outer position to erect one Used bed. Of course, the bench seat can, if necessary, have seats that can be opened so that the lower bed box, possibly closed by shutters, is accessible. With such a design of the caravan, a holder for the unused bed frame can be arranged on the 'wall of the other half-shell parallel to the direction of movement, which is then in the inner position of the H; Ibschalen is located between this wall and the back of the bench attached to one half-shell.

The optimal utilization possible by the invention of the interior of such a caravan makes it possible to use at least one of the Holbüchalen To attach facilities after the extension of the half-shell in the outer position in the direction of the enlarged interior. are extendable. Such facilities can be provided, in particular, where it is not possible for luöbel parts to reach up to

The use of groups of furniture that protrude above the bottom of the half-shell to which they are attached, makes it practically impossible to place floorboards or floorboards between the bottoms of the divergent half-shells like. to insert. Therefore, the frame surrounding the half-shells must also have a bottom, the gap between closes the bottoms of the half-shells moved into the outer position. This creates between the bottom of the frame and the bottoms of the half-shells each have a step that can be accepted if necessary. It must then, however to ensure that, for example, through Attaching suitable elevations to the bottom of the frame,

ν- the half-shells intervene, the supporting structure for

the furniture parts that protrude beyond the bottom of the half-shells find suitable support. It however, it is more pleasant if, in a further embodiment of the invention, the frame surrounding the half-shells a bottom that can be raised between the bottoms of the half-shells in the outer position “Such a floor can be easily realized

be mounted in the chassis so that it can be displaced in a vertical direction and can be lifted by means of pressure members from below on the floor. These pressure members can be formed by suitable mechanical, electromechanical, hydraulic or pneumatic devices. A particularly simple and at the same time very reliable arrangement is obtained if swivel tubs are stored in the chassis, the free ends of which can be pressed against the underside of the floor by means of a swivel device _{or the like}

In a preferred embodiment of the invention, the half-shells and the frame are arranged on a truck chassis and the half-shells are displaceable transversely to the longitudinal direction of the chassis. ^!! ~ Wohnmobii ^{!

The known caravans of the type described above are trailers in which the floors of the extendable half-shells in the stationary state are above the .wheels of the vehicle »One of these Arrangement is not possible in a mobile home. Therefore, care must be taken that the wheel arches do not interfere with the rear wheels of the vehicle and also do not hinder the extension of the half-shells. The invention also helps to solve this problem

f \ at, because the space for the wheel arch is easily thereby

that can be created in the inner position of the half-shells arranged over the entire width of the room extending furniture group in the area of the wheel arches will. In particular, in a caravan with the above-mentioned U-shaped bench is provided, the legs of the U-shaped bench are in the inner position of the half-shells over the wheel arch of the chassis. Furthermore, the Arrangement should be made so that the corresponding wheel arches are in the outer "division of the half-shells of the chassis is below the table. It it goes without saying that the bottom of the shark sharks is covered

O must have recesses for the wheel arches. the

Cover can be in the form of a tunnel through which the wheel arches can be moved, one such However, tunnels would interfere, so it is more appropriate to use moldings that can be lifted off or swung open to form the recesses to cover, which must be removed from the way of the wheel arches when the half-shells are extended and retracted.

7601151 17.1177

But it also orders the possibility of covering the recesses with a blind running around the wheel arches, which can be moved relative to the wheel arches so that it always surrounds the wheel arches and also covers the recesses in the bottom of the half-shells that adjoin the wheel arches in the sliding direction. The arrangement of such blinds therefore makes it possible to extend and retract the half-shells at will without the C J relative movement between the wheel arches and the bottoms of the

Half-shells would have to be given any attention.

The invention is described in more detail below with reference to the exemplary embodiment shown in the drawing explained. The features that can be taken from the description and the drawing can be used in other embodiments the invention can be used individually or collectively in any combination. Show it:

two half-shells 6 and 7 are arranged which, in addition to the side walls 8 and 9, protrude into the frame 5 sections of the front and rear wall as well as the ceiling and floor, which are in the longitudinal center plane of the vehicle collide when the half-shells 6 and 7 are fully retracted into the frame 5, as FIG. 1 shows. The half-shells 6 and 7 are by means of supports 10, which are attached to sections of the outer walls 8 and 9 »which over the bottom of the half-shells protrude downwards, are fastened, stored in guide rails 12, which are attached to the side members 1 of the chassis are attached. By means of suitable drive devices, the half-shells 6 and 7 can be removed from the

O Extend frame 5 to the side until the wall, ceiling

and bottom parts of the frame 5 and the half-shells 6 and 7 overlap only a little, as shown in FIGS. 2 and 4. In this way, the interior of the caravan can be compared to the state in readiness for driving, which is shown in FIG. 1 is enlarged to approximately double. Since caravans with retractable half-shells are known per se,

7601151 17.1177

-Tl-

the devices for the storage, displacement and sealing of the half-shells do not need to be explained in more detail.

The furniture in the caravan shown as an embodiment consists of one in the direction of travel left half-shell 6 in connection with the driver's cab arranged toilet and shower cubicle 21, an adjoining, Cooker 22 and sink 23 comprehensive kitchen

C "- combination 24-, one after the cab in the

in the direction of travel right half-shell 7 arranged cabinet arrangement 25 and one that extends over the entire width of the car and consists of a preferably padded bench 26 and a table 27 existing seating group «The bench is essentially U-shaped and arranged in such a way that that you the transverse web of the U-shape forming 'feil adjoins the rear walls 14 and 15 of the half-shells, while the legs extend parallel to the outer walls 8 and 9 of the half-shells. The one on the left is enough Half-shell 6 arranged legs 28 up to the kitchen device 24, while between the other leg

/ ■ • ^ and the cabinet arrangement 25 sufficient space for an in the outer wall 9 of the right half-shell 7 arranged entrance door JO remains.

The table 27 is abbreviated like a crank at the upper end The column 31 is fastened in a base 32 fastened to the bottom of the half-shell 6 on the left in the direction of travel is rotatable. In addition, the plate 27 is opposite the

7601151 17.1177

Column 31 rotatable so that its position relative to the Bench 26 can be changed in many ways. In addition, the column 31 is adjustable in height in the base 32, so that the table top 27 at the height of the seat Bank 26 can be lowered. Vie Figs. 1 and 2 show, the table top 27 has a shape that of the seat the bench 26 fills the enclosed space, so that the table top 27 in the lowered position

/ -Λ the seat of the bench 26 adjoins tightly. Make it up

then the table top 27 and the seat a substantially flat and essentially rectangular, closed surface, which can be used, for example, to build a bed can be made usable.

The plan of Fig. 1 shows that the caravan even when the half-shells are fully retracted are usable. Both the cabinet 25 and kitchen equipment 24 and the toilet cubicle 21, which can be provided with a door 33, are fully usable. Besides that there is a spacious seating area available, which is sufficient for several people to take meals or the like. O It is also possible to convert this seating area into a bed

to transform, which is completely sufficient as a bed for two people, but especially for resting with a box or the like. Is suitable.

The shape and use of the seating area is fully retained in the caravan according to the invention, because

S3 »· h. A SZ

the seating group with the help of a frame 34- is attached exclusively to the left half-shell 6 in the direction of travel, so that it is moved in its entirety together with the half-shell when the half-shells are extended to enlarge the living space. The Pig 2 and 4 show the condition of the caravan with the half-shells extended 5 and 7 Seating group creates a room that is suitable for the construction of a bed and is also used for this purpose in the illustrated embodiment is extended half-shells of the outer wall 9 of the right half shell 7 to the furniture extends and the interior of which then, for example, by opening a flap accessible. During retraction of the half shells of this bed box 35 is telescopically bilden- into a cavity 36 below the cross bridge '\ the portion of the U-shaped bench 26 pushed in, like

as indicated in FIG. This space 36 is located behind the frame 34 supporting the bench 26 and is even accessible after opening the bench. In the area between the bed box 35 and the rear wall $ 1. the right half-shell 7 is left enough space to accommodate a bed frame 37, which is parallel when not in use is set up for the rear wall 15 of the half-shell. He can

if necessary with a clamp 38 on the rear wall 15 be held. If the half-shells are retracted, the grate 37 is located behind the backrest of the bench 26, as FIGS. 1 and 3 show. To erect the bed, the grate 37 can be lifted out from behind the bed box 35 on the bed box as well as others, attached to the side walls and on the frame of the bench 26 or additionally adjustable supports are placed. The grate 37 can be designed in two parts or can be pulled out if necessary, so that it can be accommodated on the one hand in the space behind the bench seat 26 and on the other hand when extending the half-shell completely covers the lying area that has become free.

Since the bottom of the frame 5 below the bottoms of the half-shells 6 and 7, without additional measures between the bottoms of the half-shells and the bottom of the Frame 5 after extending the half-shells one step develop. Such a step is not only very annoying because it creates a trip hazard, but would also lead to the fact that the inwardly protruding sections of the furniture beyond the bottoms of the half-shells are not supported so that the leadership of the half-shells would be exposed to very strong moments. To remedy this deficiency, has in the illustrated embodiment, the frame on a movable bottom portion 41, which is with on his Underside fastened bolt 42 is guided in bearings 4-3,

which are attached to the side members 1 of the chassis'
are · In the rest position, especially when the half-shells are retracted, the bottom part 41 rests on the
I carriers of the chassis. After extending the
Half-shells, the bottom part 41 can be raised into the plane of the bottom sections by means of pressure members 44 which are formed by rods attached to the ends of crank arms 45 one end carries a worm wheel 47, in which
the worm 48 engages a drive spindle 49 mounted parallel to the side members 1 of the chassis.
By rotating the spindle 49, the shaft 46 can be pivoted with the arms, so that the pressure member formed by the rod 45 is pressed from on the bottom against the bottom part 41 and raises the bottom.

In mobile homes, i.e. caravans built on a truck chassis, the wheels pose a particular problem because, unlike conventional trailers, they protrude above the floor of the living space. So it must be in the bottom of the
Living space protruding wheel arches are provided. If laterally extendable half-shells are provided, care must also be taken that, on the one hand, the wheel arches do not prevent the half-shells from extending and, on the other hand, simple closing of the openings is possible, which are necessary to allow the relative displacement between the wheel arches and the extendable half-shells enable.

In the illustrated embodiment, the wheel arches are 51 on the movable bottom portion Λ1 of the frame attached and it has the bottoms of the half-shells 6 and a recess 52 extending to the outer wall, through which the wheel arch 51 when adjusting the side panels can slide through. In addition, on the outer walls 8 and the half-shells 6 and 7 arranged a hood 53 which encloses the wheel arch 51 when the half-shells their inner Take a stand. For this purpose, the hood 53 has a slightly larger width than the wheel arch 51 »whereas the Height can be the same because the wheel arch 51 together with the bottom section 4-1 is lowered before the half-shells are retracted. Both in the extended and in the retracted The inwardly open side of the hood 53 and the opening 52 provided in the base become through an angled cover 54- closed. It understands that this cover must be removed before the half-shells 6 and 7 are extended or retracted. Safety devices can ensure that the half-shells cannot be shifted when the covers are in place.

The covers 5 ^ can be used in a wide variety of ways be trained. It can also be one-piece ! Molded parts act, such as two flaps, one of which is on the edge of the hood 53 and the other on the Edge of the cutout 52 hinged in the bottom of the half-shells is. Furthermore, it would also be conceivable to open the opening by means of to provide a shutter-like cover, as in Pig. 5 is shown schematically. The shutter 61 is on attached to the outer wall 62 of the half-shell 63 and lies in the Area of the recess 64- of the bottom of the half-shell on the edge strips 65. In the area of the wheel house 66 is the

7601151 17.1177

Roller shutters 61 in U-shaped rails 67 over the wheel arch 66 carried away, which in this case with the chassis 68 is firmly connected. With this arrangement, the wheel house is movable under the roller shutter 61 and is without special Measures a shifting of the half-shells with respect to the middle frame 69 possible without floor openings in Appearance. Rollers 70 ensure that the Roller shutter 61 enters the U-shaped rails 67 without disruption when the half-shells are extended or retracted.

It can be seen that a caravan is created by the invention, both in the ready-to-drive state as can also be used in a stationary state with the side parts extended, and a great deal when the half-shells are extended Offers space and a high level of living comfort. It is important that not shells by extending the half only an already existing central aisle is widened, which cannot be used to put up furniture because it the access to the arranged on the long sides of the extendable half-shells furniture is blocked, but it is through the taking of one over the entire width of the vehicle extending furniture, a corner area is cleared, which can be placed in such a way, without the usability of the rest, to hinder the enlarged space anyway. The telescopic interlocking of furniture parts can result in a particularly good use of space can be achieved. The arrangement of the TJ-shaped bench in conjunction with one in the middle arranged table has in the illustrated, preferred embodiment of the invention the particular advantage that the wheel arches, which are otherwise a bit annoying, are either, when ready to drive, under the

7601151 17.1177

Legs 28 and 29 of the bench 26 or else when extended Half-shells are located under the table 27 or in the room intended for the construction of a bed, so that they do not interfere in either case.

Further, it allows for the enlargement of the interior space, for example, to provide the shower cubicle 21 with a pull inwardly cabin part 55, so that the ffutz- (bility of these cabins is increased.

It goes without saying that the invention is not limited to the illustrated embodiment, but rather deviations of which are possible without departing from the scope of the invention. The basic idea according to the invention at Caravan with two extendable half-shells on one half-shell To fasten furniture parts, which are in the inner position of the half-shells over the entire width of the vehicle extend and, if necessary, interlock telescopically, allows a multitude of possible variations to. In particular, the invention can also be used in pulled caravans. Significant uses
