    Description

    Technical Field



    [0001] The invention refers to a collapsible container, in particular a modular-segment collapsible container for freight of goods in sea, road and railroad transport and methods of folding and unfolding the container.

    Background Art



    [0002] It is a frequent situation in sea, road and rail transport that the quantity of goods transported one way, e.g. from China to Europe, is greater than the quantity of goods transported in the opposite direction. Therefore, it is necessary to transport empty containers in the opposite direction, which is non-economical because of the empty space inside the transported containers. This problem is partially solved by collapsible containers which can be folded thanks to foldable or collapsible walls, thus occupying less space during transport without goods.

    [0003] The Dutch patent no. NL2006748C reveals a collapsible transport container in which side walls are folded towards the interior of the container, and the front and rear walls are connected tiltably with the bottom of the container and are connected with fastening elements being sort of tension members with the container's roof, so with use of adequate equipment, e.g. forklift or crane, the roof of the container can be lowered, and the container is folded as a result. When folded the container's height is a few times smaller compared to the height of standard container of the same dimensions and a few such folded containers can be stacked on top of one another.

    [0004] On the other hand, document US 2014/042157 A1 relates to a freight container with side walls foldable horizontally which can be also folded by lowering the roof by means of a specialised fork-lift or crane. However, these collapsible containers require heavy equipment for folding/unfolding and they cannot be used, after being folded, for transporting any goods.

    [0005] Publication of German Utility Model Description DE 20 2008 005946 U1 titled "Kostengünstiger umweltfreundlicher Grosscontainer für den Transport unterschiedlicher Güter mit verringerten Transportkosten und geringer Umweltbelastung" describes a large container for the transport of goods with reduced transport costs and low environmental impact. The large container comprises a load-receiving rectangular support plate, a frame and a cover plate wherein the frame has two oppositely arranged, parallel to each other aligned walls and two end walls. The frame is coupled on the support plate and on the cover plate by means of fastening means. The walls have side walls that contain plastic-like materials, carbon fiber and/or glass fiber reinforced plastics.

    [0006] From Publication of International Application Description WO 2014/202802 A1 titled "Novel collapsible container", is known a collapsible container all the faces of which are rigid and flat. The container has a mechanism of hinges and guides that can be used to collapse the lateral faces onto the base plate, in an opposing manner, by pivoting one end and sliding the other towards the interior of the container, for which the vertical movement of the top plate is required. A system of this container allows the collapsing/expanding movement to be performed without substantially altering certain characteristics of conventional ISO containers. The container has doors that are taller than the width of the container.

    [0007] In turn, Publication of International Patent Application WO 01/62631 A2 titled "Freight container, system, and method for shipping freight" teaches a container that can accept standard-sized pallets and is suitable for transportation by land, sea, or air. The size and construction of the container permits the loading and removal of freight by a conventional fork lift truck through the container, and allows placement of the container in standard-sized trucks, rail cars, sea vessels, and aircraft. The freight container also is part of a system and method for transportation whereby the freight can be loaded, inventoried, locked, and sealed at a customer's premise, and remain under the custody of one entity throughout shipment of the freight to the consignee. The containers can be linked together to assist in placing several of the containers on the truck, trailer, or rail car, where they can remain linked for transportation. The containers can be brought to a customer's premise on the truck, trailer, or rail car. The containers are then loaded. Afterwards, the containers can be taken to holding areas, other trucks, ships, aircraft, or directly to the ultimate destination. Transactional information regarding the freight and destination is stored in a computer, allowing a central system to track the freight and generate appropriate business and customer documentation.

    [0008] The Publication of US Patent Application Description US 2014/263379 A1 titled "Collapsible stackable shipping container with reusable seals" discloses a reusable gasket that may be configured for use between first and second collapsible containers of a shelter. The gasket has a body configured to seal at least a portion of a seam defined between the first and second collapsible containers and at least one magnet embedded in the body. A reusable plug configured to be disposed into a cavity defined by a collapsible container has a body made of compressible foam and configured to be compressibly secured in the cavity.

    [0009] Therefore, the intention of the present invention is to provide a collapsible container, particularly a collapsible modular-segment container for sea, road and rail transport of goods, which can be folded and unfolded without using a specialised equipment dedicated for such containers.

    Disclosure of Invention



    [0010] The subject of the invention is a collapsible container according to claim 1 comprising a door part, a rear part and a central part, characterized in that the central part contains at least one collapsible module, comprising floor, roof and two side walls, wherein the first side wall is connected tiltably with its bottom edge to the floor, e.g. with use of hinges, and it is releasably connected to the roof with locking means, and the second side wall is connected tiltably with its top edge to the roof, e.g. with use of hinges, and it is supported slidably with its bottom edge on the floor, furthermore, when the collapsible module is unfolded, it is temporary fastened to the floor with a locking means. The locking means can be standard components such as a clamps, a clamping levers or a bolts and these will not be described in detail herein. The first side wall is additionally connected to the roof with use of connecting means such as, for example, articulated tension members made of bars or lines, in such a way, that once the locking means are unlocked, the roof can be lowered, holding the first side wall through the connecting means, which first side wall, while folding, is tilted towards the second side wall, and said first side wall is folded towards to the bottom, whereas the second side wall, while folding, is also tilted and folded towards the bottom, wherein the bottom edge of the second side wall is slid on the floor under the first side wall in such a way, that when the roof reaches its lower dead position, that is when it touches the bottom, the floor, roof, the first side wall and the second side wall are in the collapsed arrangement, occupying at most 25% of the height of the collapsible module before folding. In the folded position, at least one collapsible module can be inserted, particularly in a position turned by 90° in relation to the normal unfolded position, to the rear part, which is then closed directly by the door part. The connecting means can be made as e.g. two rails in the roof, and respectively two rolls, attached to the top edge of the second side wall, situated slidably in the said rails. Such solutions are known and they do not require a more detailed description. In this description the expression "unfolded" used in the context of the collapsible module refers to a collapsible module in which adjacent walls are generally connected at right angle, and the expression "folded" refers to a form of the collapsible module in which adjacent walls are inclined in relation to each other, thus forming between each other an angle of less than 20°. Preferably, after folding, the collapsible module takes maximum 20% of height of the collapsible module before folding, and more preferably, the collapsible module takes maximum 10% of the height of the collapsible module before folding. In a particularly preferable case the collapsible module takes maximum 5% of the height of the collapsible module before folding. The term "height of the collapsible module before folding" refers to a distance from the ground, on which the collapsible module is situated, to the highest point in relation to the ground measured perpendicularly to the ground. Preferably, the collapsible container contains two collapsible modules, designed to be temporary connected to one another and/or with the door part and the rear part of the collapsible container. To be more precise, each collapsible module has two assembly openings defined by the unoccupied edges of the floor, the roof and both side walls, generally corresponding to cross section of the collapsible container, wherein in the unfolded position the first assembly opening of the first collapsible module is on one side connected with the assembly opening of the door part, and on the other side it is connected with the first assembly opening of the second collapsible module, and the second assembly opening of the second collapsible module is connected with the assembly opening of the rear part. The collapsible modules after folding can be arranged in upright position, that is in a position inclined by 90° in relation to normal position in unfolded position, one beside another, and the collapsible modules arranged in such a manner, separately or joined in one group, can be placed in the rear part of the collapsible container which subsequently can be closed by the door part and locked with fastening means, thus making up a container of external length shorter than the initial length of the collapsible container before folding. Particularly preferably, the collapsible container can contain three collapsible modules, suitable for releasably connecting with one another and/or with the door part and the rear part of the collapsible container as described above, wherein said collapsible modules after folding can be arranged in upright position one beside another, and such arranged collapsible modules, separately or joined in one group, can be secured or blocked against the rear part, which can be then closed by the door part, thus making up a container of external length equal to 1/3 of the initial length of the collapsible container before folding. In the case when the collapsible module after folding occupies 20% of the height of the collapsible module before folding, a group of three collapsible modules occupies about 60% of the space in the container formed by the rear part and the door part connected together, thus leaving about 40% free space where suitable cargo can be loaded, if needed. In the case, when the collapsible module after folding occupies 5% of the height of the collapsible module before folding, the free space available for loading is equal to about 85% respectively. A group of collapsible modules can be positioned and fastened by one of the side walls or centrally along the longitudinal axis of the container to provide the possibility of uniform loading of cargo on its both sides. The roof of the collapsible module can comprise openings designed to receive a forks of the forklift, and firmly fixed side brackets, generally perpendicular to the external edges of the roof, on sides corresponding to side walls in such a way, that after folding of the collapsible module, the side brackets rest on the floor and can be locked with the roof with use of the clamps, the levers, the bolts or other standard fastening means. The door part and the rear part can be folded, however, in the presented embodiment, the door part and the rear part are not collapsible and preferably contain openings designed to receive a forks of the forklift, and a structural elements for transferring loads during transport or storage of containers one on top of another. Such structural elements can be steel L-profiles, T-profiles, closed profiles or other profiles suitable for transferring loads. In the case of freight containers for sea, rail and road transport, standardized containers of unified structure and dimensions are used, however, for the most popular types of containers the external dimensions are as follows:
    Container Type / Designationlengthwidthheight
    20', 20 ft 20'0" 8'0" 8'6"
    20 feet 6,058 m 2,438 m 2,591 m

    45 feet "Hi-Cube Pallet Wide" 13,716 m 2,500 m 2,896 m


    [0011] The following terms used herein: 20' container, 20-foot container or twenty-foot container can be used alternately and refer to standard containers of standardized dimensions as provided in the table above. The same refers to containers of other standard dimensions. Due to the fact that British Imperial System of Units is widely used in this area of technology (e.g. feet, inches), the present description contains also imperial units to define dimensions of containers, however, "feet" can be also denoted as ' and "inch" as ". Preferably, the dimension of the door part in the longitudinal direction of the collapsible container is 2,5 feet equal to 0,75725 m, the dimension of the collapsible module in the longitudinal direction of the collapsible container is 10 feet equal to 3,029 m, and the dimension of the rear part in the longitudinal direction of the collapsible container is 12,5 feet equal to 3,78625 m. The collapsible container according to the invention can contain separate stabilizing elements concealed in the recesses of the door part. Preferably, the collapsible container contains three collapsible modules and the dimension of each collapsible module in the longitudinal direction of the collapsible container is 10 feet equal to 3,029 m, wherein the total dimension of the collapsible container in the direction towards its length in the folded position is 45 feet equal to 13,6305 m. In other embodiments of the invention other dimensions of individual parts of the collapsible container are also possible. In a specific case the total length of the collapsible container after unfolding can also be equal to 48 feet equal to 14,5392 m and 53 feet equal to 16,0537 m, with adequately modified dimensions of the door part, the rear part and the collapsible module.

    [0020] The presented embodiment of the collapsible container or the method of folding or unfolding of the collapsible container does not limit the invention in any way. Various modifications are possible, e.g. a 48-foot or 53-foot container can be used instead of a 45-foot container.

    Industrial Applicability



    [0021] The advantage of the collapsible container according to the invention is its simple structure and the possibility of unfolding and folding with use of standard fork-lift of maximum load of 3,5 tons lifting capacity. Such fork-lifts are widely available in places of loading and unloading of containers, which is why such containers can be widely used also in places where there is no specialised equipment. Furthermore, in the case of collapsible modules made in the version in which they occupy less space, e.g. when three folded collapsible modules are loaded into the rear part of the collapsible container, there is still some free space left, e.g. 1/3 or 1/4 of the volume inside the rear part, directly connected with the door part, which space can be used for loading some goods.
