The utility model is a folding comfort home apartment comprising a bedroom, a dining room, a kitchen, and a bathroom unit. In its standard implementation the folded architecture can be transported by van or any other vehicle with similar cargo space, and simply unfolded on-site due to its rolling and sliding surfaces.

There are various solutions available for people who prefer to stay close to nature without being restricted to a specific location. The simplest method of course is setting up a tent, but apart from it being rather difficult to carry by hand when folded, it also does not provide adequate shelter against the occasional cold nights and certain weather conditions. The other obvious solution is to rent a camper van, but such specific-purpose vehicles are usually not available in every car rental facility, which means that most vacationers would have to travel disproportional distances even to be able to rent the proper vehicle. Those who prefer to travel as discussed will typically have their own camper vans, but understandably this is not a satisfactory alternative for everyone due to the financial ramifications as it requires a separate vehicle along with all its maintenance costs. However, with our application, all equipment described above becomes unnecessary, since we are implementing an independent apartment house equipped with all essential functions, foldable for travel to a size that easily fits a van with an average-size cargo space, or even a trailer. Hereafter we will list a few descriptions that are in some respects relevant to our invention. The description registered under US2012242103 and titled„EXPANDING MOBILE UTILITY STRUCTURE” features a trailer system of a mobile utility structure with expandable folding side panels. The invention does not essentially correspond to our solution presented in the utility model, only in saving space and being expandable. A fundamental difference is that this invention depicts an independent trailer unit with its own undercarriage, therefore it differs from our invention in its core idea, requiring a larger expenditure and maintenance costs. Similarities only occur in that the size of the base unit is expandable. The description registered under US201 1056146 and titled „HOUSING UNIT MODULE AND CORRESPONDING HOUSING UNIT” also describes a housing unit, but its design is very simple, as visible from the available dimensions. Contrary to our invention, it does not contain as many rooms and it has fewer appliances. As a basic unit it can only be transported outside of a vehicle, just like the previous description, but it does not have its own wheel. The Chinese description registered under CN205601686 and titled „MULTI - FUNCTIONAL DOUBLE-DECK CAR AS A HOUSE OF COLLAPSIBLE EXTENSION” introduces a camper van with an expandable inner space when certain wall elements are folded out. This also being an independent vehicle, its purpose is the same but the idea and implementation fundamentally differ from our utility model.

A major disadvantage of the aforementioned inventions is that their transport requires a dedicated vehicle designed for the specific purpose, or one that is considerably altered in its design. Another essential difference is that the floor space in our equipment, when fully unfolded, is four times its original size, while the structures in the inventions discussed above only use the floor space of the cargo space, or its double at most. Furthermore, our invention can be placed into and removed from a van, and contrary to the aforementioned inventions, the van does not need to be converted. Consequently, in our opinion there is no equipment similar to our compact folding unit in the market or among the patented inventions that would offer similar appliances and design, catering to most demands and featuring several separate rooms, while also maintaining simple transportability. All this without requiring a dedicated vehicle. Thus, we believe that the mobile apartment house can fill an existing market niche and offer an alternative to countless campers. Another important and noteworthy difference is the largest available headroom and the lock mechanism. Our invention can be implemented with an automated, remotely controlled lock. As for the available headroom, the height of the bedroom is the same as the headroom of the original unfolded box, while the height of the other rooms can extend to more than 2 metres.

Our objective was to design an apparatus that improves on the drawbacks of the inventions described above and that comes close to, or even surpasses, the comfort provided by a stationary apartment house. Concurrently, due to its size and expandability, it can be transported inside a van with average cargo space without conversion. The 2-metre plus headroom is available when in the last step of the unfolding process the room footing becomes expandable (in the central unit, the dining room, the kitchen, and the bathroom). Our aim is therefore to create an apartment house that fits and can be transported inside a van, converting the van into a camper van while not requiring any modifications in the vehicle itself. The van does not lose its original function, it can still be used to transport people or goods when the folding apartment house is removed.

The subject of the invention, then, is a mobile apartment house that is suitably foldable and can be affixed to a box-body vehicle or trailer. Opening and closing the unit can be performed by automatic mechanism or remote control, if required. The said transportable mobile unit features several rooms and is aimed at providing a solution for holiday-makers requiring an apartment house without renting or maintaining a camper van, and who wish to avoid the troublesome aspects of using a tent.

The mobile apartment house is basically a foldable mobile apparatus providing modem conveniences, comprising several units, with the following main components: sleeping area, central unit, expandable dining room and kitchen, and a bathroom. The standard design may also be extended by other built-in features in further practical implementations. The former version is suitably equipped with two single beds and one double bed, providing sleeping accommodation to 4 people. This can be expanded to host 6 people if needed. The house is equipped with camping side rooms, a bath and a mini kitchen containing an induction or gas stovetop and a dishwasher sink with tap. Additionally, the unit contains a fridge, a foldable table, chairs, and kitchen utensils. A further benefit is that the walls of the house are good insulators due to their material. This way nn summer one can avoid the inconvenience of an overheated, stuffy airspace, while in winter the ideal temperature can be easily maintained.

The solar modules placed on top of the central unit of the house serve and charge the accumulators used to provide electricity is suitable weather. Of course, external networked power sources can also be connected to the central system in the house. Keeping savings and efficiency in mind, lighting uses modem LED technology. If required, a television set and an air conditioner can also be installed to increase comfort.

The subject of the utility model is a mobile apartment house where all expandable units are contained within the sleeping area when folded. When installed independently, its weight is carried by its own supporting structures, while unfolding from the cargo space after transport is supported by the positioning and anchoring elements. The central unit can be unfolded unto the frame at the bottom of the sleeping area after unfolding a support beam attached by hinges. Moreover, the central unit also has further supporting structures. A further expansion is the dining room, kitchen and bath unit, which can be expanded sideways from the central unit. There are large openings on either side of the bedroom, suitably covered with polycarbonate, to provide natural light. The headroom of the central unit, as well as of the dining room, kitchen and bathroom can be expanded to a level exceeding that of the sleeping area by way of expandable footings for the rooms. The opening procedure described above can of course also be automated to make unfolding and folding considerably simpler. Loading and unloading the mobile home from the transport vehicle does not require expertise or qualification, it can be performed by a one adult following the instructions. Installation does not take more than 5-10 minutes. The entire opening sequence can be automated, meaning that it can be remotely controlled and motorized, but of course the cost- effective manual procedure is also viable. Consequently, within a few minutes of parking, a complete mobile home is ready for use for recreation and holidays, while the cargo space of the transport vehicle is fully unloaded, and its capacity is freed up.

Diagram one, two and three depict the apartment house in its closed form but placed on 7 the support structures. In this form only the 5 large opening of the 1 sleeping area is visible. The 9 support beam providing support to the 8 central unit, until lowered, is folded up to allow easy transport and to save space, and touches the front panel of the central unit, suitable fixed by hinges, but its anchor point from where it is lowered is suitably located on the lower frame of the sleeping area. Before opening/sliding out the central unit, the 9 support beam is lowered to act as a load-bearing structure and support the central unit - see Diagram five. The 8 central unity is rolled out from the 1 sleeping area, thereby doubling the size. The 8 central unit can be further supported by a 9 support beam. Diagram seven displays the first phase of opening the 3 dining room and the 4 kitchen and bathroom unit, where the top is unfolded, after which Diagram eight displays the finished opened state of the former units. To create a headroom of 2 metres or more, the 2 room footing is extended as a supplement for the 8 central unit, the 3 dining room and for a portion of the 4 kitchen and bathroom. Diagram ten displays one of the suitable implementations of the utility model where the apparatus is fully opened, with the 8 central unit extended from the 1 sleeping area, and thereby shielding it, the 9 support beam carrying its weight, and the 3 dining room and 4 kitchen and bathroom pulled out sideways, along with the 2 folding room footings to expand the headroom. The above outline is depicted in Diagram eleven from a side view, where the 5 large opening at the side of the 1 sleeping area, acting as a natural light source, is also visible. Diagram twelve displays the method of transport for the entire unit when folded in the back of an average-size van. Simple rollout and anchoring is ensured by the 7 positioning and anchoring bumper. It is not necessary to slide out the apartment house from the van to fully set it up: in this case, the 1 sleeping area remains in the back of the van, the 9 support beam is lowered and the 1 central unit is pulled out, as depicted in Diagrams thirteen and fourteen. Similarly to when set up independently, the apartment can still be _, expanded by the 3 dining room and the 4 kitchen and bathroom, and with the 2 expandable room footings. Some mobile sections of the house can be moved around by sliding mounts either mechanically by hand or by automation. The end of these sliding mounts have 7 positioning and anchoring bumpers to allow precise positioning. With regard to power savings, the 1 bedroom has 5 large openings to provide natural light, suitably covered by polycarbonate sheets that can be opened. The 8 central unit has a 4 kitchen and bathroom and a 3 dining room expandable sideways. Both expandable units can be replaced into their respective internal sliding frames when transported, located in the 1 bedroom and the 8 central unit, creating a space-saving, compact, easily transportable unit. If required, the architecture can be equipped with further fixtures to provide more comfort. Additional comfort includes the feature that the headroom in several rooms can reach more than two metres, as described previously. One of the preferable implementations of the utility model is, therefore, a compact, foldable apartment house that can be transported in a van. When transported, the apartment house has its 8 central unit slid into the 1 sleeping area, including the 3 dining room and the 4 kitchen and bathroom that are expandable sideways, while their headroom can be extended due to the 2 expandable room footings. Initially, the 1 bedroom unit with its 5 large openings on either side, covered by polycarbonate, remains in the van, the 9 support beam is lowered in the front, after which the 8 central unit is slid out unto this support structure, which can then be expanded on either side to a 3 dining room and a 4 kitchen and bathroom. If required, the headroom can be further expanded with the 2 folding room footings that can be folded from the 8 central unit, the 3 dining room and the 4 kitchen and bathroom. Stability of the opened unit is ensured by the 6 foldable support structures anchored to the 1 bedroom and the 8 central unit, of which the ones under the 1 bedroom will of course remain unfolded if the unit is not rolled out from the van. When installed independently, the unit is rolled out from the van, and the 7 positioning and anchoring bumpers are fixed to ensure easy mobility. Folding and unfolding the mobile unit, that is its folding rooms, before and after transport can be done mechanically by hand, but also in an automated manner by remote control.

The advantage of the folding comfort apparatus described above is that it can be transported in the back of an average-size van. As opposed to the current state of technology, it does not require the conversion of the van. After the apparatus is removed, the van regains all of its original functions. The 2 folding room footing is an additional benefit, allowing the extension of the headroom in some rooms of the unfolded apartment house the extend above the headroom of the van, even above 2 metres. This means that our apparatus does not require a dedicated vehicle such as an independent camping van or a caravan. And due to its size, it can be transported in an average-size cargo space.
