SELF-SUPPORTING, REMOVABLE, FITTED-QUT UNIT FOR A
VEHICLE.
Description
Technical Field
The present invention relates to travelling leisure- time activities such as, for example, camping or caravanning and in particular relates to a fitted-out unit, in particular for living purposes, which can be transported in a van, is self-contained and can be separately removed from the said van. Background Art
At present, camping tents of various shapes and sizes, tent trailers which can be towed by an associated vehicle and also living units which can be mounted on a self-propelled vehicle, such as campers (dormobiles, motor-homes, vans, semi-converted vehicles, etc.) or small dwellings which can be transported on trailers or mounted in the bodies of lorries and trucks (including so-called pick-ups) are known.
The said living units, which may be classified as transportable, irrespective of their specific name or design category, are associated with the corresponding vehicle by means of conversion and adaptation operations
which are fairly major, in terms of both aesthetic and functional requirements, so much so that obtaining approval for roadworthiness is secondary to the need to comply with the specific constructional standards and type-approval requirements.
Consequently the vehicles must be designed for a particular and exclusive use and cannot be used for purposes other than this: all this has negative repercussions on the construction, insurance, operating and running costs and the effective use of the capital invested for the purchase of said vehicle. Disclosure of invention
The object of the present invention is to overcome these drawbacks by means of a fitted-out unit which can be associated with a vehicle provided with a loading compartment, but which is self-contained and separate from the latter so that it can be rapidly and easily removed from the said vehicle, whenever required.
In accordance with the invention, this object is achieved by a fitted-out unit according to the preamble of Claim 1, characterized in that it comprises a self- supporting, removable, variable-volume shell structure which can be inserted into the loading compartment of the vehicle via the associated doors, in its contracted state, and which can then be expanded inside the loading
compartment until it occupies the maximum space permitted and vice versa.
The shell structure is formed so that it can be associated with the compartment, being able to be adapted easily to the internal obstacles which, in particular, consist of the top part of the vehicle's wheels which project above the loading surface and towards the inside of the compartment. For this purpose, the fitted-out unit is designed such that it can be introduced into the compartment via the doors, its width then varied horizontally so to overcome the internal obstacles of the wheels, and can then be expanded heightwise, above the upper level of the door, until it reaches the maximum height permitted by the loading compartment of the van. Since the vans made by various manufacturers have dimensions which are very similar, the shell structure can be easily made with shapes and modular dimensions such that it can be housed inside the compartments of different vans. The fact that the unit can be removed from the van whenever required means, on the one hand, that all the intrinsic transportation requirements of the van may be left unchanged and, on the other hand, that the unit may be used, if necessary, as a fitted-out unit placed on the ground, i.e. the van and the fitted-out unit may be used
together or separately, depending on requirements, without the need for particular assembly or reassembly operations, without the need to comply with particular type-approval requirements and without tying up a significant amount of capital.

Detailed description of the preferred embodiment (s)
With reference to Figures 1 to 7 of the attached drawings, 1 denotes in its entirety a unit fitted-out for a vehicle 2, such as a conventional van, provided with a closed loading compartment 3 which is accessible from the outside via associated doors 4.
The fitted-out unit 1 essentially comprises a self- supporting, removable, variable-volume shell structure 5
which can be inserted into the loading compartment 3 of the vehicle 2 via the doors 4, in its contracted state, and which may then be expanded inside the loading compartment 3 until it occupies the maximum space permitted and which, vice versa, may be removed from the van with exactly the reverse sequence of operations.
The shell structure 5 is provided in particular (Figures 8 and 13) with a base 6 designed to rest on a loading surface 7 of the vehicle 2; in the base 6 three main characteristic parts, indicated by 8, 9 and 10, respectively, may be distinguished.
A first part 8 thereof may be associated with the loading surface 7, relative to the direction of travel of the vehicle 2, in front of the planwise volume 11 of the wheels 12 in the said loading plane 7; as is known, said wheels 12 project with their upper part towards the inside of the loading compartment 3 (Figure 1) .
A second part 9 may be associated with the loading surface 7 at the rear of the planwise volume 11 of the wheels 12 in the said loading plane 7. Finally, a third part 10, located in between the first two, may be associated with the loading surface 7 by means of its part 13 which projects towards the underlying loading surface 7 (Figure 16) and which has a width 16 not greater than the distance 14 lying, transversely with
respect to the direction of travel 15, in the loading plane 7, between the planwise volumes 11 of the wheels 12 of the vehicle 2.
The height 17 of the projecting part 13, on the other hand, is not less than the maximum heightwise dimension 18 of the wheels 12 which project from the loading surface 7 towards the inside of the loading compartment 3 of the vehicle 2.
The first part 8 and the third part 10 of the base 6 are designed to have a variable geometry, at least as regards their horizontal planwise dimension which can be measured transversely with respect to the direction of travel 15 of the vehicle 2.
This dimension may be selectively varied between a maximum width x2, corresponding to the maximum expansion of the base 8 permitted by the dimensions of the loading compartment 3, and a minimum width xl, not greater than the distance 14 lying, in the loading plane 7, between the planwise volumes 11 of the wheels 12 (Figure 1) . As will be clarified more fully below, the maximum width x2 relates to the condition where the fitted-out unit 1 is used as an area for housing persons, while the minimum width xl relates to the need to make the unit 1 more compact so as to allow it to be freely slidable horizontally, on the loading surface 7, without being
hindered by the wheels 12.
More particularly (Figure 14) , the first part 8 of the base 6 comprises two vertical, separate, rigid structures 19 which are oriented parallel to the side walls 31 of the loading compartment 3, namely are facing each other and situated on either side of a vertical plane parallel to the direction of travel 15. Guide means 30 are envisaged for translation of said structures 19, horizontally and transversely with respect to the loading compartment 3, in a condition arranged as close as possible to each other or as far away as possible from each other, corresponding to the said minimum width xl and maximum width x2 of the first part 8 of the base 6.
Walls ' 22 conveniently equipped with various furnishing and functional accessories intended for the particular use of the unit 1 - shown by way of example also in the cross-sections thereof illustrated in Figures 9-12 - are incorporated into the vertical structures 19 mounted above the base 6. A canopy 20, which is supported by the vertical structures 19 forms the upper roofing of the unit 1. Said roofing is therefore entirely separate and physically isolated from the surrounding walls of the loading compartment 3 of the vehicle 2 or the van. In the case where the latter is provided, as is
frequently the case, with access doors 4 which at the top are lower than the roof 32 of the loading compartment 3, the unit 1 comprises means for raising or lowering the canopy 20 above the vertical structures 19 previously described.
In accordance with a first embodiment - shown schematically in Figure 17 in which the rigid walls 22 of the loading compartment 3 extend over most of the height of the said loading compartπtent 3 and the canopy 20 is also constructed in rigid form - these raising means include top surfaces of the inclined and converging walls 21 and the matching, sloping, i.e. diverging side sections 23 of the canopy which rest slidably on the inclined top surfaces 21. The inclined top surfaces 21 of the walls 22 interact with the side sections 23 so as to raise the canopy 20 when the walls 22 are moved away from each other into the fully expanded condition of the unit 1 and, vice versa, so as to cause lowering of the canopy 20 when they are moved towards each other.
A different constructional form of the raising means, which is particularly advantageous for a canopy 20 which includes a support structure 25 and a covering canvas (Figures 14 and 15) , envisages the use of upright elements 24 arranged between the canopy 20 and the walls
22. These upright elements 24, which support the structure 25, are slidably fastened to the walls 22, or differently - but in an equivalent manner from a functional point of view - may be made in telescopic form. In either case the upright elements 24 are selectively displaceable with respect to the walls 22 so as to move the canopy 20 away from or vice versa towards the associated top surfaces, thus allowing the fitted-out unit 1 to expand or contract along the vertical . Another possible embodiment of the canopy 20 and the associated raising means may be obtained by means of a tensile structure which incorporates at least one or more inflatable air chambers 27.
The means for raising the canopy 20 may be in this case actuated by compressed air which, introduced into the chamber 27 at a suitable pressure, rigidifies the structure, expands it as required and provides it with the capacity to support itself above the rigid walls 22 of the fitted-out unit 1. To summarise, the fitted-out unit 1 may be made more compact (Figures 2, 3 and 4) until has minimum dimensions suitable for allowing it to pass through the doors 4 towards the loading compartment or be extracted from the said loading compartment 3; then, once it has been inserted into the loading compartment 3, it may be
expanded up to the maximum dimensions permitted, as shown by way of example in Figures 5, 6 and 7.
In order to facilitate extraction of the unit 1 from the loading compartment 3 or insertion thereof into the same loading compartment 3, the base 6 of the fitted-out unit 1 is provided with legs 28 for resting the shell structure 5 on the ground. Preferably, the legs 28 are permanently connected to the base 6 and are made as a folding structure so that they may be extracted from the said base during use and concealed inside the latter when not used. The legs 28 are provided finally with wheels 29 for the rolling displacement, on the ground, of the shell structure 5.
The invention therefore fully achieves the predefined objects and offers many advantages. One of the advantages consists in the fact that the van does not require any external or internal modification. In its travelling state it retains all the characteristics for which it was built: it has a convenient design, without projecting parts,, offers full visibility and does not have any of the classic unaesthetic features of vans which have been converted into campers. Finally, the unit 1 does not interfere with the driver's cab.
During use of the unit 1, the rear doors must simply be opened (Fig. 12) together with the side door of the
parked van so as to free the door for access to the unit and the windows of the bathroom and kitchen/dinette zone (parts 8-10 in Figure 8) .
The empty van is the same van used for business and trading activities or services and therefore there is no variation in the costs for road tax, insurance and maintenance. The unit 1 in the "expanded" state (Figures 9, 11) , in addition to being housed independently inside the van, may be parked in camping sites (Figures 5, 6) and lived in, thereby freeing the van for use. The unit 1 described, in particular intended for living purposes, may be used for other purposes, such as, for example, as an office, gym or small workshop, albeit while remaining within the scope of protection of the present patent. It is evident that the invention thus conceived may be suitable for applications on an industrial scale and may be subject to numerous modifications and variations all falling within the scope of the inventive idea. Moreover, all its details may be replaced by technically equivalent elements.
