Patent Application
20240391687
The present invention relates generally to the field of shipping containers, also known as sea containers, freight containers, cargo containers, etc. Such containers are designed to meet standardized transporting, lifting and stacking requirements, i.e. they are designed to be conveniently moved from one mode of transport to another and thereby eliminating the need to unload the cargo from the first mode of transport and load the cargo to another mode of transport. Virtually the entire global shipping container market has adapted the standard of the International Organization for Standardization (ISO).
Further, the present invention relates specifically to the field of shipping containers that are transformable between a reduced configuration and an erected configuration, i.e. known as telescopic, foldable or collapsible shipping container, such that each container occupy less volumetric footprint and more containers may be transported together when the container is in the reduced configuration. The container comprises a top segment and a bottom segment, wherein the container bottom segment comprises a rigid base panel having four corner fittings and the container top segment comprises a rigid roof panel having four corner fittings. The container comprises four corner posts each extending between a roof corner fitting and a base corner fitting and comprising a top element rigidly connected to the roof panel and a bottom element rigidly connected to the base panel, each corner post having a retractable/extendable configuration.
It is also known to use collapsible shipping containers as shelters, temporary housing or other temporary buildings, for instance at places suffering from weather disasters in order to provide temporary shelter/houses for the suffering people, at music festivals to provide a better alternative to tents, at sport events to provide headquarter for the sport event management, at temporary military base camps to provide headquarter and troop-rooms, etc. These containers may be reused many times at different locations.
One example is disclosed in US 2014/0263306, wherein the container has a collapsed configuration for transport and an erected configuration when in use. This container is designed such that each side panel has a top element hinged to the roof panel and has a bottom element hinged to the base panel and the top element and the bottom element are also hinged to each other, thereby the side panels will become double folded into the interior of the container when the container is in the collapsed configuration. Thereto the front-end panel and the back-end panel, together with the corner posts belonging to them, are hinged to the base panel and are also folded into the interior of the container when the container is in the collapsed configuration. Thus, when the container is in the collapsed configuration, the roof panel is lowered and secured to the base panel and virtually the entire interior of the collapsed container is filled with the end panels and side panels. Thus, the collapsible container may not carry any other cargo, furniture, fixtures, etc. when in the collapsed configuration. Thereby, any furniture, fixtures, etc. need to be separately transported in parallel to the collapsible container. WO 2010/022347 discloses another example of a telescopic container, wherein the top elements of the side panels are rigidly connected to the top panel and the bottom elements are rigidly connected to the base panel. The disclosed configuration will have difficulties to comply with the standard of the International Organization for Standardization (ISO) both when erected and collapsed.
Thus, there is a need to provide a shipping container that fulfil all regulations/standards in the erected configuration and in the reduced configuration, and that is transformable between a reduced configuration and an erected configuration, and that is able to carry all the necessary cargo, equipment, furniture, fixtures, etc. needed when the container is used in the erected configuration also when used/transported in the reduced configuration.
The present invention aims at obviating the aforementioned disadvantages and failings of previously known containers that are transformable between a reduced configuration and an erected configuration, and at providing an improved container. A primary object of the present invention is to provide an improved container of the initially defined type that may carry all the necessary cargo, equipment, furniture, fixtures, etc. needed when the container is used in the erected configuration also when transported in the reduced configuration. It is another object of the present invention to provide a container, which is weatherproof both in the reduced configuration and in the erected configuration.
It is yet another object of the present invention to provide a container which may be lifted and stacked both in the reduced configuration and in the erected configuration. It is also an object of the present invention to provide a container that can be transformed between the erected configuration and the reduced configuration multiple times.
It is another object of the present invention to provide a container which is transformed between the reduced configuration and the erected configuration, and vice versa, using the crane that is used for lifting the container from the truck, the railway-wagon, etc. It is yet another object of the present invention to provide a container wherein a maximum mutual displacement between the top segment and the bottom segment is guaranteed.
According to the invention at least the primary object is attained by means of the initially defined telescopic shipping container having the features described herein. Preferred embodiments of the present invention are further described herein.
According to the present invention, there is provided a telescopic container of the initially defined type, which is characterized in that the container comprises a front-end panel having at least one hinged door leaf, wherein the door leaf comprises a top section pivotably connected to the top element of the adjacent corner post, a bottom section pivotably connected to the bottom element of the adjacent corner post, and an intermediate section that is in telescopic engagement with the top section of the door leaf and with the bottom section of the door leaf, wherein the intermediate section interconnects the top section and the bottom section.
Thus, the present invention is based on the insight that the telescopic container is made up of two main components/segments, i.e. a male container half comprising the base panel and a female container half comprising the roof panel, wherein when the container is in the reduced configuration the female container half is lowered over the male container half leaving enough floor area and interior volume to carry all the necessary cargo, equipment, furniture, fixtures, etc. needed when the container is used in the erected configuration also when transported in the reduced configuration. Thereto, the present invention is based on the insight that the container is subject to extreme and tough handling and thereby requires a reliable design/structure adapted to stand such handling without jeopardizing the transformability over time, at the same time as the container may be opened and closed at any time, i.e. when the container is in the reduced configuration, in the erected configuration and therebetween. Thus, part of the top section and part of the bottom section of the door leaf does not overlap each other when the container is in the reduced configuration, and the entire door leaf is pivoted (opened/closed) as a single element both in the erected configuration and in the reduced/collapsed configuration.
According to various embodiments of the present invention, the container comprises at least four hinged girder assemblies, wherein each girder assembly comprises an upper end pivotably connected to the container top segment and a lower end pivotably connected to the container bottom segment, the girder assemblies being in upright position and supporting the container top segment when the container is in the erected configuration.
According to various embodiments of the present invention, the girder assemblies are secured in the upright position when the container is in the erected configuration, in order to prevent mutual displacement between the container top segment and the container bottom segment when the container is in the erected configuration. Thereby, when the girder assemblies are in the upright position and carries the entire load of the container top segment, the girder assemblies as such are prevented from departing from their upright position.
According to various embodiments of the present invention, the girder assemblies are secured in a folded position when the container is in the reduced configuration, in order to prevent mutual displacement between the container top segment and the container bottom segment when the container is in the reduced configuration. Thereby, when the girder assemblies are in the folded position, the girder assemblies as such are prevented from departing from their folded position and the container may be lifted in the container top segment and still remain in the reduced configuration.
Further advantages with and features of the invention will be apparent from the following detailed description of preferred embodiments.
The terms FIG., FIGS., Figure, and Figures are used interchangeably in the specification to refer to the corresponding figures in the drawings.
A more complete understanding of the abovementioned and other features and advantages of the present invention will be apparent from the following detailed description of preferred embodiments in conjunction with the appended drawings, wherein:
The present invention relates to a telescopic shipping container, generally designated 1, that is transformable between an erected configuration and a reduced configuration, i.e. a configuration having reduced height. The reduced configuration is preferred when the container 1 is handled, transported, stored, stacked, etc. and the erected configuration is preferably only used when the container 1 is in use. The container 1 shall be construed to be capable of being handled without any permanent deformation when lifted in conventional manner, and shall comply with the requirements of the CSC (Convention for Safe Containers) and applicable ISO standards.
The interior of the container 1 may be pre-equipped with electric wiring including lamps, power sockets, etc. and the container 1 may externally comprise a male contact for connecting the internal electric wiring to the power mains, to an electric generator, to solar cells located on top of the container 1, etc., i.e. the container 1 may be prepared for being plugged-in. Thereto the interior of the container 1 may be pre-equipped with furniture, such as beds, tables, chairs, storage cabinets, water closet and sink to be connected to drain and water mains, etc. It is important that the furniture shall not obstruct the container 1 to reach the reduced configuration.
The container 1 comprises two major components, reference is initially made to
The container bottom segment 2 comprises a rigid base panel 4 having four base corner fittings 5, and the container top segment 3 comprises a rigid roof panel 6 having four roof corner fittings 7. The container 1 comprises four corners, wherein each corner extends between a roof corner fitting 7 and a base corner fitting 5. The container 1 lacks weight carrying corner posts, but the corner posts are configured to provide structural stability/strength to each of the top segment 3 and bottom segment 2 and to provide guiding during transformation between the erected configuration and the reduced configuration.
Preferably, the roof panel 6 and/or the base panel 4 comprise insulation, and at least the outer layer of the base panel 4 and the roof panel 6 is preferably made of metal. The inner layer of the base panel 4 may be constituted by a wooden/plastic/metal floor. The base panel 4 and/or the roof panel 6 may be equipped with forklift fittings 8 configured for being lifted by means of a forklift, preferably in conformance with ISO standards. The forklift fittings 8 comprise suitable drain/rinse holes.
The base corner fittings 5 and the roof corner fittings 7 are preferably standardized corner fittings designed in conformance with ISO 1161. Thereby the container 1 may be lifted at the roof corner fittings 7 by means of spreaders fitted with hooks, shackles, twistlocks, etc. and be lifted at the base corner fittings 5 using slings with terminal fittings, hooks or equivalent. The container 1 may also be transported and secured by means of twistlocks or equivalent at the base corner fittings 5 and/or the roof corner fittings 7. The eight corner fittings, i.e. the four base corner fittings 5 and the four roof corner fittings 7, together define the outer boundaries of the volumetric footprint of the container 1. Thus, when placing multiple containers 1 side by side and/or one on top of the other, the corner fittings of adjacent containers 1 will contact each other. The corner fittings are made of metal. The container 1 may also comprise additional lifting shackles or the like, adjacent the roof corner fittings 7.
The container 1 comprises wall panels extending between the roof panel 6 and the base panel 4. Preferably, the wall panels comprise insulation, and at least the outer layer of the wall panels is preferably made of metal.
According to various embodiments, the container 1 comprises two opposite side panels 9, wherein each side panel 9 comprises a top section 10 rigidly connected to the roof panel 6 and constitutes part of the container top segment 3 and comprises a bottom section 11 rigidly connected to the base panel 4 and constitutes part of the container bottom segment 2. According to various embodiments, the top section 10 and the bottom section 11 of each side panel 9 are in telescopic engagement with each other. The top section 10 is preferably located outside the bottom section 11, i.e. the bottom section 11 is more or less entirely covered by the top section 10 when the container 1 is in the reduced configuration.
According to various embodiments, the container 1 has an overall elongated shape, wherein the side panels 9 are longer than the width of the container 1. However, the side panels 9 may have equal length as the width of the container 1, or the width of the container 1 may be wider than the length of the side panels 9. The width and length of the container 1 is preferably in conformance with standard shipping containers, i.e. ISO standard, such as 20-feet, 40-feet, etc.
In addition to the side panels 9, the container 1 also comprises a front-end panel 12 (see
According to various embodiments, the container 1 comprises at least four hinged girder assemblies 15, wherein each girder assembly 15 comprises an upper end pivotably connected to the container top segment 3 and a lower end pivotably connected to the container bottom segment 2. Thus, the upper end of the girder assembly 15 is journaled/pivoted about a pin/pivot 16, wherein the pin/pivot 16 is connected to the container top segment 3. Preferably, the pin/pivot 16 is connected to an ear/plate 17, or the like, that is connected to the roof panel 6. Thus, the lower end of the girder assembly 15 is journaled/pivoted about a pin/pivot 18, wherein the pin/pivot 18 is connected to the container bottom segment 2. Preferably, the pin/pivot 18 is connected to an ear/plate 19, or the like, that is connected to the base panel 4 and/or to the bottom element of the corner post.
The hinged girder assemblies 15 prevent unwanted disconnection of the container top segment 3 from the container bottom segment 2, when the top segment 3 is lifted from the bottom segment 2 in order to transfer the container 1 from the reduced configuration to the erected configuration. The bottom segment 2 is kept on the ground by its own weight when the top segment 3 is lifted from the reduced configuration. When the girder assemblies 15 has reach the maximum displacement, the container bottom segment 2 will be lifted together with the container top segment 3 via the girder assemblies 15.
The four hinged girder 15 assemblies are distributed/allocated such that the girder assemblies 15 is associated with one corner of the container 1 each, i.e. the individual girder assembly 15 is located near the associated corner of the container 1.
The girder assembly 15 is displaceable between an upright position when the container 1 is in the erected configuration and a folded position when the container 1 is in the reduces configuration. According to various embodiments, the pin/pivot 16 at the upper end of the girder assembly is located vertically above the pin/pivot 18 at the lower end of the girder assembly. When the container 1 is in the erected configuration and the girder assemblies 15 are in the upright position, the girder assemblies 15 support the container top segment 3, i.e. the weight of the container top segment 3 and any extra weight added on top of the container 1. Thereto, the girder assemblies 15 carry the weight of the bottom segment 2, together with the cargo, when the container 1 in the erected configuration is lifted from the ground. The girder assembly 15 is preferably prevented from moving/displacing in the transverse direction of the container 1, i.e. along the extension of the pivots 16,18, when the container 1 is in the erected configuration, for instance by the plate 19.
According to the disclosed embodiment, each girder assembly 15 comprises an upper arm 20 and a lower arm 21 pivotably connected to each other. It shall be pointed out that the upper arm 20 and/or lower arm 21 may be constituted by one element each or by parallel elements or a combination thereof.
According to various embodiments, each side panel 9 comprises at least two hinged girder assemblies 15, i.e. one at each end of the side panel 9 associated with the corners of the container 1. One or more extra girder assemblies may be located intermediate the corners of the container 1, especially when the container 1 is long (for instance a 40-feet container).
According to various embodiments, the bottom section 11 of the side panel 9 of the container bottom segment 2 is a double wall construction (see
According to various embodiments, the top section 10 of the side panel 9 of the container top segment 3 is a double wall construction, wherein the hinged girder assembly 15 is located between the inner and outer wall of said double wall construction in order to protect the girder assembly 15 as such and to secure its operation and also in order to protect operators and cargo located inside the container 1 during transformation of the container 1. According to other embodiments, the top section 10 of the side panel 9 of the container top segment 3 only comprises an outer wall (see
According to various embodiments, the girder assemblies 15 are secured in the upright position when the container 1 is in the erected configuration, in order to prevent mutual displacement between the container top segment 3 and the container bottom segment 2 when the container 1 is in the erected configuration, i.e. preventing the top segment 3 from going down.
Thus, the container 1 comprises a securing element 22, e.g. a pin, ratchet, etc., that is in engagement with the girder assembly 15 and the container bottom segment 2 in order to prevent displacement of the girder assembly 15 from the upright position. The securing element 22 is preferably in engagement with the girder assembly 15 and the ear/plate 19 that is connected to the base panel 4 and/or to the bottom element of the corner post. The securing element 22 is according to various embodiments maneuverable/accessible from the outside of the container 1 through an opening 23 in the bottom section 11 of the side panel 9 of the container bottom segment 2. The opening 23 is preferably covered by a lid or the like. According to the disclosed embodiment a securing element 22 in the shape of a pin is in engagement with a hole 24 in the girder assembly 15 and with a hole 25 in the ear/plate 19. When the container 1 is transformed into the erected configuration, i.e. when the top segment 3 is lifted max in relation to the bottom segment 2 and the girder assembly 15 is in the upright position, the securing element 22 is easily engaged/disengaged. It shall be pointed out that it is the girder assemblies 15 as such when located in the upright position that support the weight of the container top segment 3 and any additional weight. It shall be noted that the ear/plate 19 may divided into two separate members, i.e. a lower member for pivotably connection of the lower end of the girder assembly 15 and an upper member for engagement with the securing element 22.
According to various embodiments, the angel between the upper arm 20 and the lower arm 21 of the girder assembly 15 is less than 180 degrees when the girder assembly is in the upright position and equal to or more than 160 degrees, preferably equal to or more than 170 degrees. Thereby, when not locked in the upright position, the girder assembly 15 will automatically fold when the container top segment 3 is lowered. According to various embodiments the girder assembly 15 is biased by a spring element from the upright position, such that the girder assembly 15 will automatically fold when the container top segment 3 is lowered. Different combinations are also conceivable.
According to various embodiments, the girder assemblies 15 are secured in the folded position when the container 1 is in the reduced configuration, in order to prevent mutual displacement between the container top segment 3 and the container bottom segment 2 when the container 1 is in the reduced configuration, i.e. preventing the top segment 3 from going up.
Thus, the container 1 comprises a securing element 26, e.g. a pin, ratchet, etc., that is in engagement with the girder assembly 15 and the container bottom segment 2 in order to prevent displacement of the girder assembly 15 from the folded position. The securing element 26 is preferably in engagement with the girder assembly 15 and the ear/plate 19 that is connected to the base panel 4 and/or to the bottom element of the corner post. The securing element 26 is according to various embodiments maneuverable/accessible from the outside of the container 1 through an opening 27 in the top section 10 of the side panel 9 of the container top segment 3. The opening 27 is preferably covered by a lid or the like. Preferably the opening 27 in the top section 10 is aligned with the opening 23 in the bottom section 11 when the container 1 is in the reduced configuration.
According to the disclosed embodiment a securing element 26 in the shape of a pin is in engagement with a hole 28 in the girder assembly 15 and with the hole 25 in the ear/plate 19. When the container 1 is transformed into the reduced configuration, i.e. when the top segment 3 is lowered max in relation to the bottom segment 2 and the girder assembly 15 is in the folded position, the securing element 26 is easily engaged/disengaged. When the securing element 26 is in engagement, the container bottom segment 2 will follow the container top segment 3 when the top segment 3 is lifted, e.g. in the roof corner fittings 7, i.e. the container 1 will remain in the reduced configuration.
It shall be pointed out that if the securing element 26 is not present, the container 1 may be lifted in the reduced configuration by lifting in the container bottom segment 2, e.g. in the base corner fittings 5 or the forklift fittings 8 in the container bottom segment 2.
