MODE(S) FOR CARRYING OUT THE INVENTION

(16) Further described examples of embodiments of expandable container shelters according to this technical solution refer to FIG. 1 to FIG. 14. Said figures show shelters 2, or their parts on one side of a container 1, however, these figures, at the same time, illustrate also examples of embodiments with the shelters 2 at both sides of the container 1 because building of the shelter 2 at the other side of the container 1 is in fact analogous.

(17) In general, embodiment of the expandable container shelter according to this technical solution, which is the most preferred in regard of maximal area covered and handling, comprises the container 1, two pairs of horizontally swivelling supporting frames 3 comprising auxiliary swivelling frames 4 and two roofs 6, attached on inflatable beams 5, where one pair of swivelling supporting frames 3 together with one roof 6 attached on the inflatable beams 5 is placed at one long side of the container 1, and the other pair of the swivelling frames 3 together with the other roof 6 attached on the inflatable beams 5 is placed at the opposite long side of the container 1. In this way, symmetrical, sufficiently rigid structure composed of the container 1 and two shelters 2 placed by long sides of said container 1 is created.

(18) Further, generally the most preferred position of opened supporting frames 3 is mutually parallel and perpendicular to the container 1. However, it is possible also to create an object of different shape, for example trapezoidal or rhombic, by applying different lengths of the supporting frames 3.

(19) The first example of embodiment of the expanded container shelter according to this technical solution described hereinafter, is shown in FIG. 1 and FIG. 2.

(20) Pair of supporting frames 3 is mounted in vertical pivotal mounts on the opposite ends of the container 1 on each longitudinal side of the container 1. Specifically, each one of the supporting frames 3 is with its one end mounted in one pivotal mount. Each supporting frame 3 comprises a pair of horizontal beams 31 with vertical reinforcements 32 and auxiliary frames 4 at free ends of the supporting frames 3. These auxiliary frames 4 have in this example similar structure as supporting frames 3, thus comprise a pair of horizontal beams 41 with vertical reinforcements 42. This particular arrangement of supporting frames 3 and auxiliary frames 4 is shown in FIG. 9.

(21) In closed configuration, the supporting frames 3 are placed inside the container 1 in different planes and thus maximal length of one supporting frame 3 can practically be equal to dimension of the inner length of the container 1. The auxiliary frame 4 of the supporting frame 3 is in this example provided such that it does not project out over the thickness of the supporting frame 3. This is advantageous in regard of space saving when the supporting frame 3 is folded. The auxiliary frame 4 is in this example pivotally mounted in the supporting frame 3 by its one edge. Length of the auxiliary frame 4 is in this example equal to half of the distance between the supporting frames 3 in opened working position, i.e. when unfolded supporting frames 3 are parallel.

(22) After setting up the container 1 at desired place, supporting frames 3 are one after the other opened. Afterwards, the auxiliary frames 4 are unfolded from these frames 3. It is preferred to secure opened supporting frames 3, and if appropriate, also the auxiliary frames 4 in their pivotal mounts. It is possible the structure such created further preferably stabilize by connecting the ends of the auxiliary frames 4 with members 7 for securing of horizontal position of the supporting frames 3 and/or the auxiliary frames 4, which can be commonly used, preferably height-adjustable, supports, legs, baseplates, and similar, or also wheels, runners and similar, which can help even during the step of unfolding of the frames 3, 4. This structure, if necessary, can be further strengthened also using corner reinforcements 9 which can stabilize the frames 3, 4 against each other, or the supporting frames 3 against the container 1, or diagonal reinforcements 33, 43 which reinforce the frames 3, 4 individually. Said steps are schematically shown in FIGS. 6, 7 and 8. Sides of the frames 3, 4 can be preferably in advance covered by solid or flexible material, thereby preparing walls of future object and saving time for installation.

(23) Afterwards, said structure is ready for installation of the roof 6. The roof 6 comprises, in this example, beam 5 which are at one end connected to the container 1 and at the other end to the auxiliary frames 4, as shown in FIG. 1, or the beams 5 are connected to opposite supporting frames 3, as shown in FIG. 2. In this example of embodiment, roof 6 supports 5 are arcuate inflatable beams. The roof 6 is conventionally of canvas type, made of flexible material, or combination of flexible and not flexible material, preferably impregnated or coated fabric.

(24) Making use of arcuate inflatable beams as roof 6 supports 5 is very advantageous due to following reasons.

(25) The arcuate inflatable beam 5 is easily transportable, folded or rolled, together with the shelter 2 roof 6. The beam 5 can be permanently connected with material of the roof 6. Folded or rolled roof 6 including deflated beams 5 can be stored in the container 1 separately.

(26) Preferably it is however possible to connect at least one side of the roof 6 together with one side of the roof beams 5 permanently to the container 1, in the case the beams 5 are arranged in direction transversal to the length of the container 1; or the beams 5 can be permanently connected to at least one supporting frame 3 in the case when the beams 5 are arranged in direction accordant to the length of the container 1.

(27) During transportation, folded roofs 6 together with deflated beams 5 are contained inside the container 1. One side of deflated beams 5 is then preferably suspended under a ceiling of the container 1 in holders, for example in guiding grooves, to be possible for the ends of the beams to be easily moved to the edge of the container 1, i.e. to working position, when the shelter 2 roof 6 is being assembled.

(28) Remaining part of the beams 5 and the roofs 6 is then hanging folded under the ceiling of the container 1, or this part of the beams 5 and roofs 6 is lying folded at the bottom of the container 1 and only a part of said beams 5 and roofs 6 corresponding approximately to the height of the container is hanging. It is preferred to suspend the roofs 6 completely, because a space is then left at the bottom of the container 1 for storing of other possible parts of the shelters 2, for example floor, or if necessary auxiliary inflatable tent, as well as technical equipment such as air conditioning unit, power generators or air compressor that can be used also for inflating the beams 5. Said arrangement is not shown in figures, as it is sufficiently clearly described and conceivable.

(29) The roofs 6 such placed and accessories are during transportation thus practically situated in central part of the container 1 and closed by pair of supporting frames 3 from both sides. It is preferred, in order to maintain standard dimensions of the container 1, especially in the case of ISO container, when outer side of the outer supporting frame 3 does not project out over the outline of the container 1.

(30) After the roof 6 with beams 5 is unfolded, free end of the beams 5 is attached, with known anchoring members, to the opposite side of the structure, i.e. to the auxiliary frames 4, or to the opposite supporting frame 3. Afterwards, the roof 6 is attached on the periphery with commonly available attaching means used for canvas type roofs, usually to the edges of the shelter 2 structure, which are in this case the container 1, supporting frames 3 and auxiliary frames 4. Possible ways of attaching of roof 6 periphery vary upon requirements for water-proofing, air-proofing, time of installation and other conditions, while their embodiment, if it is over the entire periphery, does not influence functionality of the assembly itself.

(31) In the case, a floor is also a part of the container 1, preferably coiled on a roll inside the container 1, it is unrolled as the first to protect the roof 6 against dirtying of its inner side. Afterwards, the roof 6 is unfolded on the floor and further work continues as described in preceding paragraph.

(32) Roof beams 5 are then inflated, thereby stretching the roof and strengthening the entire structure of the shelter 2. Inflating the beams 5 is carried out in known ways form known sources of compressed air, for example by means of standardized compressor hoses and connectors from a compressor or air cylinder, if appropriate by means of electric blower and similar.

(33) It is not necessary, however appropriate for the sake of thoroughness, to mention that when building the shelters 2 on both sides of the container 1, it is advisable to at least open the supporting frames 3 from the container 1 on both sides of the container 1 simultaneously due to optimal mass balance.

(34) Short sides of the container 1, that is front and rear walls, can be provided by swivelling wall serving as access floor, onto which an inflatable tent can be folded during transportation, or they can be provided by regular access doors, or technical equipment can be placed onto one of the sides, either permanently placed outside on holders, or during transportation, placed inside the container 1 and closed by the wall of the transportation container.

(35) Another example of embodiment of expandable container shelter according to this technical solution described hereinafter is shown in FIG. 3 and FIG. 4. In this example of embodiment, the bottom structure of the shelter 2 composed basically of the container 1, supporting frames 3 and auxiliary frames 4, is substantially identical with that as described above in the example of embodiment according to FIG. 1 and FIG. 2. Instead of inflatable beam 5, the support 5 is provided as solid beam. Various knows forms of arcuate, bent or straight beams, made of metal, composite, wood, or other suitable material can be used as the solid beam 5.

(36) In the case of use of solid beams 5, arcuate or bent, which upper edge is longer than roof span, that is the distance between longitudinal edge of the container 1 and auxiliary frames 4, or between the supporting frames 3, i.e. arcutate or bent beams, it is expected that material of the roof 6 folded or rolled separately without the beams 5.

(37) During installation of the roof 6, the beams 5 are attached to the bottom structure of the shelter 2 and the roof 6 is stretched upon their surface, or in suspended configuration, the roof 6 is pulled to the beam 5, or the beams 5 are installed from the underside as the last ones and the entire roof 6 is stretched by pushing the beams 5 into their given position on the bottom structure of the shelter 2. Also, as schematically shown in FIG. 3, the roof 6 can be installed between the beams 5 by means of Keder slid into a luff groove provided in the beams 5. These mentioned ways of installation of the roof 6 can also be similarly used with the inflatable beams 5.

(38) Another example of embodiment of expandable container shelter according to this technical solution described hereinafter is shown in FIG. 5

(39) In this example, straight beams 5 are used whose upper edge has approximately the same length as is the roof 6 span, that is in this example the distance between the supporting frames 3. The roof 6 is permanently attached to the beams 5 and is stored inside the container in folded or so called accordion shape. In such case, installation would be most preferably carried out by unfolding the roof 6 by means of a guiding rail or groove in the supporting frames 3 guiding the ends of straight beams 5.

(40) In this example of embodiment, the supporting frames 3 can be shaped as shown in FIG. 12. It is preferred then, in order to increase rigidity of such structure to provide the supporting frames 3 at their end with members 7 for securing their horizontal position, e.g. in the form of legs.

(41) Further, in this example of embodiment according to FIG. 5, in the case of connecting, of free ends of the supporting frames 3 with the auxiliary frame 4 at least in the form of horizontal beam 41, the roof supports 5 can be arranged parallel to the supporting frame 3. Then, the roof 6 would unfold by means of guiding rail or groove on the container 1 and the auxiliary frame 4.

(42) Example of embodiment of expandable container shelter according to this technical solution, where the supporting frames 3 are placed in closed configuration inside the container 1 in one plane and maximal value of the sum of lengths of the supporting frames 3 is equal to the value of the inner length of the container 1, is shown in FIG. 13 and FIG. 14.

(43) In the example of embodiment shown, length of the supporting frame 3 is equal to the half of the inner length of the container 1. The supporting frames 3 can be provided as extendable. It means that sliding extension part 8 is slid in the supporting frame 3, which, after the supporting frame 3 is opened, slides out and extends the supporting frame 3 by the length of this extension part 8. This particular embodiment is shown in FIG. 14.

(44) Above described examples of embodiments shown on attached drawings do not exhaust all possibilities of embodiments of expandable container shelter according to this technical solution. Other embodiments of expandable container shelter within the idea of this technical solution and in the scope of the claims can be provided by further combining described parts and their arrangements. Such embodiments can be provided upon requirements for placement or use of the expandable container shelter in particular real-life situations.
