TECHNICAL FIELD

The present invention relates to a foldable house, a system comprising such foldable house and a method for raising the foldable house.

BACKGROUND

A swimming pool in a private garden or similar is often appreciated during the warmer months of the year. Nowadays, swimming pools are common also in less warm countries. In these countries, the weather may be unpredictable also during the summer. In order to make as much use as possible of the swimming pool it would be advantageous to have a possibility of easily transforming an outdoor swimming pool into an indoor swimming pool.

According to regulations in some countries, an outdoor swimming pool must be fenced or enclosed in some way for safety reasons. It would be advantageous if the fencing could constitute a part of an enclosure of an outdoor swimming pool transformed into an indoor pool.

A pool may be used for only a part of a year, but it may require a large share of the available garden area of a house. It would be beneficial if this area could be used for other purposes when the pool is not in use.

From the above it is understood that there is room for improvements and the invention aims to solve or at least mitigate the above and other problems.

The present application relates to a collapsible/foldable house 1 , also referred to as a pool house 1 , configured to be provided in relation to an outdoor swimming pool/pool 5. The pool house 1 has a collapsed state, in which it serves as a pool cover or a pool deck, and a raised state, in which it houses a pool 5 which is transformed from an outdoor pool to an indoor pool. In the raised state, the foldable house 1 could also or alternatively function as garage/storage/veranda/patio.

Fig. 1 shows the foldable pool house 1 in the collapsed state. The pool house 1 comprises a lower deck portion 2 arranged to be located around the periphery of the swimming pool 5. The lower deck portion 2 preferably extends along the circumference of the pool 5. The lower deck portion 2 may have a rectangular, square, oval, round or any other suitable shape.

The pool house 1 further comprises an upper deck portion 3. The upper deck portion 3 is arranged to be located approximately flush against the lower deck portion 2 in the collapsed state of the pool house 1 , as shown in Fig. 1 . The upper deck portion 3 may comprise a hatch 4 or similar, preferably with the same or larger size and shape as the water surface of the pool 5. In the collapsed state of the house 1 , when the hatch 4 is closed, the upper deck portion functions as a pool cover, preventing access to the pool 5. In the collapsed state of the house 1 , when the hatch 4 is open, the upper deck portion 3 functions as a pool deck, the hatch 4 providing access to the pool 5. The hatch 4 may be formed in any suitable way, e.g. as a sliding door, operable by hand or by motorized means. In the raised state of the house 1 , the upper deck portion 3 serves as a roof of the house 1. On a lower side of the upper deck portion 3, i.e. the side facing the lower deck portion 2, at least three pillars 6 are attached to the upper deck portion 3. The pillars 6 extend through or outside of the lower deck portion 2, depending on the size of the lower deck portion 2. In the folded state of the house 1 , the pillars 6 extend into tubes 7 provided in the ground, as shown in Fig. 1. The pillars are provided with elevating means 8 configured to raise and lower the upper deck portion 3. The elevating means are preferably motorized, but may also be hand driven. The elevating means 8 comprises e.g. a nut, into which one of the pillars 6, provided with threads, is inserted. By rotating the pillar 6, the pillar 6 will rise, and bring the upper deck portion 3 upwards. The elevating means 8 is preferably arranged below the lower deck portion 2 in order not to be visible. The length of the pillars 6 correspond to the roof height of the house 1 in the raised state of the house 1. The pillars 6 are configured to form the load-bearing construction when the collapsible house 1 is raised.

Alternatively, the pillars 6 are telescopically formed such that they comprise sections which are insertable into each other. Thus, in the folded state of the house, the sections of each pillar 6 are telescoped into one another and thus only a portion of the total length of each pillar 6 extends into the ground.

In another embodiment (not shown), the elevating means 8 comprises one or more cogwheels driven by an electrical motor.

The lower side of the upper deck portion 3 is further provided with a rail device 12. The rail device 12 either comprises two rail portions extending along the length of two sides of the upper deck portion 3. Or, the rail device 12 comprises a rail extending along three of the sides of the upper deck portion 3. This will be further described below.

The house 1 further comprises a wall assembly 9 configured to be arranged adjacent the pool 5. The wall assembly 9 may be fixedly attached to the ground. Alternatively, it may be configured to be stored in a space in the ground when it is not in use and being displaceable upwards to the ground surface when the house 1 is to be raised. The mechanism for displacing the wall assembly 9 into and out of the ground may be any suitable displacement means. Alternatively, the wall assembly 9 is configured to be located flat on the ground when the house 1 is in the collapsed state. When the house is to be raised, the wall assembly 9 is raised, e.g. via a hinge, and fastened in the raised state.

The wall assembly 9 comprises a first, stationary wall portion 10 and a movable wall sub-assembly 19. The first wall portion 10 is configured to form one long side of a rectangular pool house 1 (alternatively one side of a square pool house 1). The movable wall sub-assembly 19 comprises a second wall portion 13, and, hingedly 16 connected thereto, a third wall portion 14 and a fourth wall portion

15, see Fig. 8. The second wall portion 13 is connected, by means of a hinge device

16, to the third wall portion 14 in one vertical side portion. The second wall portion 13 is connected by means of a hinge device 16, to the fourth wall portion 15 in an opposite vertical side portion.

The wall sub-assembly 19 is displaceable along the rails of the rail device 12 arranged on the lower side of the upper deck portion 3. The rails extend between the side of the upper deck portion 3 adjacent the first wall portion 10 and an opposite side thereof.

The house further comprises a control unit 22, preferably arranged on the first wall portion 10. The control unit 22 is configured to control the movement of different parts of the foldable house 1 . The control unit 22 is configured to be either maneuvered by a user, or to be controlled by actual weather data, predicted weather data, time, season, any other suitable data or any combination of these.

Now referring to Fig. 2, the process of raising the pool house 1 from the collapsed or folded state will be described.

First, the upper deck portion 3 is raised from its position flush against the lower deck portion 2. The upper deck portion 3 is raised by means of the elevating means 8, e.g. by rotating the threaded pillars 6 through the associated nuts such that the pillars 6, and thus the upper deck portion 3, is raised. When the upper deck portion 3 has reached its top position, it constitutes the roof of the pool house 1 .

Next, the wall assembly 9 is brought to its upright position, if it has been lowered to the ground, or it is raised from the space in the ground up to the ground surface. If the wall assembly 9 has not been lowered to the ground, or lowered into the ground but is standing in its position on the ground surface, this step is omitted.

Thereafter, the wall sub-assembly 19 is transferred onto a first end portion of the rail device 12 and transported along the rail device 12 to an opposite end portion of the rail device 12, also referred to as an end position. In the end position, the second wall portion 13 is located on an opposite side of the pool 5 in relation to the first wall portion 10, and the first 10 and second 13 wall portions form opposite sides, preferably long sides, of the pool house 1. The wall sub-assembly is preferably transferred by means of a transfer means driven by an electrical motor 21 .

For forming the remaining sides, preferably short sides, of the house 1 , the third wall portion 14 and the fourth wall portion 15 are pivoted by means of the hinge devices 16 into an end position in which they are parallel with each other and perpendicular against the first 10 and second 13 wall portions. Thus, the third 14 and fourth 15 wall portions are attached to the second wall portion 13 by means of the hinge 16, and in the end position they are configured to be fastened to the first wall portion 10 and/or the ground as well. The fastening may be accomplished in any suitable way, e.g. a latch, hasp, or similar. In order to facilitate the pivoting movement of the third 14 and fourth 15 wall portion, rails may be provided on the lower side of the upper deck portion 3. The pivoting movement is preferably performed by means of transfer means driven by one or more electrical motors 20, preferably arranged on the second wall portion 13.

Thereafter, the upper deck portion 3 is lowered to a final position, which is lower than the top position. In this final position, the upper deck portion 3 secures the wall portions 10, 13, 14, 15 by pressing them downwards towards the lower deck portion 2. By these steps, the outdoor pool 5 has been transformed into an indoor pool 5 by means of folding up the collapsible house 1. By performing the reverse steps, the house 1 is collapsed again, and the pool 5 is once more an outdoor pool 5.

Alternatively, as shown in Figs 9-10, the third 14 and fourth 15 wall portions are pivoted from hinges 16 of the first wall portion 10. The second wall portion 13 may be located adjacent the third 14 and fourth 15 wall portions in the collapsed state of the house 1 (Fig. 9), or between the first wall portion 10 and the third 14 and fourth 15 wall portions (Fig. 10). In the case of the second wall portion 13 being arranged between the first wall portion 10 and the third 14 and fourth 15 wall portions, the third 14 and fourth 15 wall portions are pivoted as a first step of assembling the house 1 , releasing the second wall portion 13. Thereafter, the second wall portion 13 is transported along the rails 12 to form the house 1.

Alternatively, see Fig. 11 , the wall assembly 9 comprises two wall sub-assemblies 19a, 19b. The first sub-assembly 19a comprising the first wall portion 10, and hingedly 16 attached thereto, a first part 14a of the third wall portion 14, and a first part 15a of the fourth wall portion 15. The second wall sub-assembly 19b comprises the second wall portion 13, and hingedly 16 attached thereto, a second part 14b of the third wall portion 14 and a second part 15b of the fourth wall portion 15. In the end position, when the house 1 is raised, the parts 14a, 14b, 15a, 15b of the third 14 and fourth 15 wall portions are configured to be pivoted by means of the hinges 16 to extend along a straight line, respectively, each line being perpendicular against the horizontal extension of the first 10 and second 13 wall portions. Another embodiment of the house 1 is shown in Figs 3-4 and 12. The basic construction complies with the embodiment described in connection with Figs 1 and 2. The reference numbers of corresponding features applies also to this embodiment. However, in this embodiment, the wall assembly 9 comprises a first wall portion 10 and a wall sub-assembly 19 formed as a set of jalousie wall segments 17. That is, the wall sub-assembly 19 comprises several wall segments 17, linked to each other, e.g. by means of hinges 16. Each wall segment 17 is preferably approximately two meters wide, but the width may vary between 0.2 and 4 meters.

Also in this embodiment, the rail device 12 is provided on the lower side of the upper deck portion 3. In this embodiment, the rail 12 extends along all sides of the upper deck portion 3, also along the side adjacent the first wall portion 10. The rail device 12 may comprises curved corner portions in order to facilitate movement of the wall segments 17 there along. The jalousie wall segments 17 each comprises means for engaging with the rail device 12 such that the jalousie wall segments 17 are able to be transported along the rail device 12.

The collapsible house 1 is raised in the same manner as described before, but the wall segments 17 are moved along the rail device 12, such that three walls are formed. When the house 1 is to be disassembled, the wall segments 17 are moved in the opposite direction along the rail device 12.

Yet another embodiment will now be described in relation to Figs. 5-6. The foldable house 1 in this embodiment comprises the same features as in the embodiments described above, but the pool 5 is enclosed by a fencing structure 18, such as a fence, a plank, a wall etc. which may be made of wire, wood, bricks etc. This is required in many countries in order to prevent accidents related to the pool. The height of the fencing structure 18 is e.g. 0.9 meters (legal requirement in Sweden).

The wall assembly 9 of this embodiment comprises the first wall portion 10, and either a second 13, third 14, and fourth 15 wall portion, or alternatively a set of wall segments 17, as in the previously described embodiments. A difference is that the wall portions/segment 13, 14, 15, 17 extend from the full height of the first wall portion 10 and down to the height of the fencing structure 18. I.e. the height of the wall portions/segment 13, 14, 15, 17 equals the difference between the height of the first wall portion 10 and the height of the fencing 18. Together, the wall portions/seg- ments 13, 14, 15, 17 and the fencing structure 18 are configured to form complete walls. The fencing structure 18 is preferably provided with a slot/groove/rail 33 on its upper portion along which the wall portions/segments 13, 14, 15, 17 are movable.

Fig. 6 shows the wall segments 17 of the above described jalousie wall type wall assembly 9 being partly pulled out from the starting position of the wall assembly 9.

As illustrated in Fig. 7, this embodiment provides a possibility to let furniture 23 and other items remain in the pool area, i.e. on the lower deck portion 2, when the house 1 is raised, provided that the height of the furniture 23 is lower than the height of the fencing structure 18. The hatch 4 of the upper deck portion 3 is open, and the furniture 23 etc. is arranged within the hatch 4 opening, on the lower deck portion 2. When raising the house 1 , the upper deck portion 3 is raised, thereafter, the hatch 4 in the upper deck portion 3 is closed. The wall portions 10, 13, 14, 15, 17 are then transported from their folded position to the unfolded position along the top of the fencing structure 18. The furniture 23 etc. remains below the fencing structure 18 and are not affected by the raising of the house 1.

In one embodiment, the lower deck portion 2 is provided with a hatch (not shown). By closing this hatch, access to the pool 5 is prevented. The hatch may be used to transform the pool house 5 to other purposes. By raising the collapsible house 1 and closing the hatch in the lower deck portion 2, the house 1 may be used for any purpose such as garage, storage, veranda or similar.

If the house 1 is equipped with the wall assembly 9 shown in Fig. 11 ,]) the size of the house 1 may be customizable. First, the hatch of the lower deck portion 2 is closed. Then, the upper deck portion 3 is raised to form a roof, and the wall subassembly 19b is moved halfway across the horizontal length of the raised upper deck portion 3. Thereafter, the wall portions 14b, 15b of the second wall sub-assembly 19b are pivoted such that they are parallel with each other and perpendicular to the first 10 and second 13 wall portions, and are attachable to the first wall portion 10. Thus, a house 1 is formed having only half the area compared to the full-sized house, and having a roofed area adjacent to the house 1 , to be used e.g. as a patio.

Alternatively, the house 1 being formed is a garage located next to the pool 5. In this embodiment, as other garage embodiments, the first wall portion 10 is provided with a garage door (not shown). The pool 5 is in this case covered by the roof, but no walls are provided around the pool 5, only the fencing structure 18. In this embodiment, the first wall portion 10 comprises a garage door (not shown).

Another version of the garage embodiment is shown in Figs 13-14. The first wall portion 10 and the wall sub-assembly 19 are arranged a suitable distance from the pool 5. The suitable distance equals an appropriate size of a garage, e.g. 5-8 meters. In this embodiment, the upper deck portion comprises a first portions 3a and a second portion 3b. The first upper deck portion 3a is configured to be arranged above the pool 5. The second upper deck portion 3b is configured to be arranged above the garage portion 24. The second upper deck portion 3b is tiltable in relation to the first upper deck portion 3a, e.g. by means of hinges (not shown). As in earlier embodiments, the lower portion of the upper deck portion is provided with rails 12, and a fencing structure 18 is surrounding the pool 5. The house 1 of this embodiment may comprise six pillars 6 in order to support the upper deck portion 3a, 3b in its raised position.

The hatch 25 for covering the opening in the lower deck portion 2 is provided partly below the floor in the garage portion 24 and/or partly below the lower deck portion 2. The hatch 25 is e.g. suspended on rollers 27 or similar. A groove 28 is provided around the inner circumference of the pool 5 to receive the hatch 25 in the position where the pool 5 is covered.

In the garage portion 24, there is a recess 26 in the floor, coverable by means of a cover 29. The recess is covered in Fig. 13 and exposed in Fig. 14. The recess 26 is sloping towards the first wall portion 10. At least one, preferably two, openings are provided in the recess 26 in order to provide access to the hatch 25 there below. The recess 26 is shown from above in Fig. 15, and the hatch 25 is visible through the openings 31.

When the upper deck portion 3a, 3b has been raised, the wall sub-assembly 19 is transported along the rails 12. The wall sub-assembly 19 may be transported to a first position A or a second position B. The wall sub-assembly 19 in position A forms a closed garage and a sun-roof 3a above the pool 5. The wall sub-assembly 19 in position B forms a large closed garage (with hatch 25 in lower deck portion 2 closed) or a large house 1 with an indoor swimming pool 5 (with hatch 25 in lower deck portion 2 open).

In Fig. 14, the hatch 25 is being closed. First, a vehicle 30 (car, electric car, or any other suitable vehicle) has entered the garage portion 24. Thereafter, the cover 29 has been removed in order to expose the recess 26. The vehicle 30 is backed into the recess 26 such that the tires of the vehicle 30 contacts the hatch 25 exposed through the openings 31 in the recess 26. As the vehicle 30 continues to back, the hatch 25 will slide in the opposite direction carried by the rollers 27. When the hatch has reached the groove 28 on the far side of the pool 5, the vehicle 30 can be driven forward, out of the recess 26, and the recess closed by means of the cover 29 in order to form a flat floor in the garage portion 24. In order to open the hatch 25 again, the procedure is reversed. As long as the vehicle 30 is in the garage portion 24, the battery of the vehicle may be used for powering the electrical devices of the collapsible house 1 such as electrical motors for moving the wall portions, raising the upper deck portion etc. If the vehicle is an electric car, the battery may be charged by means of solar panels arranged on the upper surface of the upper deck portion 3, i.e. on top of the roof. Preferably, the electrical car has a solar panel on the roof for charging during travelling. The same charging system is preferably used when charging the battery via the solar panels of the collapsible house 1. The battery may be used both for vehicle propulsion and for powering electrical components of the house 1 .

The floor of the garage portion 24 may comprise raiseable stopping means (not shown), preventing the vehicle from driving too far forwards and/or backwards when maneuvering the hatch 25.

In one embodiment, the house 1 comprises a control unit configured to control one or more motors to perform one or more of the following: control the height of the pillars 6, control the movement of the wall assembly 9, control the movement of the wall sub-assembly 19, control the motion of the wall portions/segments 10, 13, 14, 15, 17, control the hatches of the upper 3 and/or lower 2 deck portions.

The control unit may be configured to have access to time, date, and/or weather data and be configured to tilt the upper deck portion 3 being in the raised position by controlling the height of one or more pillars. The tilting of the upper deck portion 3 provides shadow to the pool area dependent on the height of the sun. If the upper deck portion 3 is equipped with solar panels, the control unit may be configured to tilt the roof according to the solar radiation angle to optimize the output of the solar panels.

The roof formed by the upper deck portion 3 in its raised position may be configured to be a flat roof, a pent roof, a gable roof, a butterfly or V-roof, an inverted V-roof, a pitched roof or any other suitable form of roof or combination thereof. The different forms of roof are accomplished by raising e.g. two of the pillars 6 to a higher or lower level compared to the remaining pillars 6. Different inclinations of the roof are accomplished by varying the difference of the height between the raised pillars 6. The walls portions 10, 13, 14, 15 are preferably shaped in accordance with the shape of the roof. If the wall portions 10, 13, 14, 15 are not used, the upper deck portion 3 may be tilted into any suitable inclination, e.g. for collection of rainwater or for adapting the inclination of solar panels towards the sun. Preferably, rainwater is collected from the upper deck portion 3 when located in the raised position. The rainwater may be used to refill the pool 5, or for other purposes such as irrigation or watering. Since the house 1 also may be equipped with solar panels, it may be self-supporting and off-grid.

In one embodiment, the house 1 comprises a heat exchanger (not shown), e.g. an air to air heat exchanger for heating the inner of the raised house 1 such that the pool 5 may be used also during cooler seasons. Alternatively, or additionally, the house 1 may comprise an air conditioning unit (not shown). This is preferred if the house is located in an area with warmer climate.

The various embodiments described above are provided by way of illustration only and should not be construed to limit the invention. Those skilled in the art will readily recognize various modifications and changes that may be made to the present invention without following the example embodiments and applications illustrated and described herein, and without departing from the scope of the present disclosure. All wall elements may be provided with suitable one or more window, door, hatch, garage door and/or half door (the bottom part of the half door may be arranged in the fencing structure and the upper part in the movable wall portion) which may be customizable from case to case depending on where the house is to be located and how the surroundings are shaped. The doors are preferably lockable as this may be required in some countries.

The wall portion may be of symmetrical or asymmetrical lengths. The upper deck portion 3 and/or the wall portions 10, 13, 14, 15 are provided with suitable flanges or cams in order to form space for movement/tilting of the upper deck portion 3 when it functions as roof.

The hatches 4, 25 in the upper and lower deck portions 2,3 may be formed as single hatches or as several sub-hatches, depending e.g. of the size, material, opening structure etc.

The upper deck portion 3 may comprise solar panels/collectors configured to act as both pool deck, roof, electricity generator and/or heat generator. Possibly, the solar panels are connected to the control unit and may be controlled to be inclined in relation to the course of the sun. The solar panels may be arranged on beams which are tiltable in two directions. Thus, it is possible to control the inclination of the solar panels according to one or more of the following: longitude and latitude of the location of the house 1 , date, time of day etc. such that the inclination in relation to the sun is optimal. The above description described that the wall portions and pillars are moved/transferred etc. by transfer means powered by electrical motors, but the movements may be accomplished in any suitable way, e.g. by hand, by any other suitable kind of motor, or by a combination of by hand by motors. The above description refers to a pool house arrangeable above an outdoor swimming pool, but other applications are possible as well. For example, the collapsible house may be arranged above an earth cellar or other underground storage house. The house may be a pool house, a garage, a storage house, a veranda or a patio.
