Title Modular storage construction

Water is vital to life. One of the sustainable development goals of the United Nations is to ensure access to water and sanitation for all. According to the WHO and UNICEF, 1 in 3 people globally did not have access to safe drinking water in the years 2000-2017. This is even more in rural areas. These rural areas lack access to clean water from a general water supply, are difficult to reach, and often have limited resources.

The invention relates to a modular storage construction. A modular storage construction can be tailored to a custom size when constructing, and can easily be transported as it can be delivered as a kit of separate objects.

US 2014/0076891 A1 describes a fastening system for modular containers. The system comprises at least two panels with one or more securing apertures formed through a first panel and one or more engaging projections provided on a second panel, each one of the engaging projections being sized and positioned to be engageable with a corresponding one of the securing apertures of the first panel. It, however, requires engaging projections to be disposed or provided on the second panel, thereby requiring material, and resources to mount the engaging projection on the second panel. This fastening system therefore has the drawback of being relatively complex in construction.

It is an object of the invention to provide a modular storage construction that lacks the above- mentioned drawback or at least to provide an alternative modular storage construction.

The invention provides a modular storage construction comprising: a plurality of interconnected panels forming a standing circumferential wall of the storage construction, wherein the plurality of interconnected panels comprises a first panel having an extension and an adjacent second panel having an opening that cooperates with the extension of the first panel to form a connection, wherein the extension is integrally formed in the panel and bent into a hook shape that extends through the opening.

The modular storage construction has, among others, the advantage that its production process requires fewer resources than the modular storage construction in prior art as the connection holding the panels together is mainly formed by the panels themselves.

Also, a storage construction according to this invention has the advantage that it simplifies the process of building a storage construction, making it even more suitable for places where the users are not familiar with advanced construction techniques.

Since the hook shaped extensions are bent out of the plane of the panel, the panels may be flat before bending. The panels can be easily transported as they stack on top of each other in a compact way. One could arrange engaging projections on panels after transportation.

However, this requires more resources at the construction site which is not desirable. A storage construction according to the disclosure in this document is thus is especially useful in but not limited to for example, difficult to reach areas such as rural areas.

Each panel can be of any suitable shape for example square or rectangular. The height of the panels can be any size, for example a height between 50 cm and 1000 cm, for example 150 cm. The width of a panel can be any size, for example a width between 10 cm and 1000 cm, for example 100 cm or 112 cm. lt is possible to have panels of different sizes within one storage construction for example an altering width of the panels of 100 cm and 112 cm. The extensions of the panels can be located at the edge of the panel or in the panel itself. In the latter case, a recess is made in a shape such that one or more extensions are formed in the panel. This can be done by laser cutting , mechanical cutting or other suitable methods. The openings in the panels can also be created by laser cutting, mechanical cutting or other suitable methods.

Optionally, a panel can be pre-shaped to have a curvature which is similar to or is close to the curvature of the panel in the assembled storage construction.

A panel may be a corrugated panel. Corrugated panels can also be stacked up on each other when transported. The corrugatedness of the panels may increase the stiffness of the construction.

In an embodiment, the panel has two opposite sides with multiple openings and/or extensions. For, example one of the two opposite sides may be provided with only openings or only extensions and the other opposite side may be provided with only openings or only extensions. It is also possible to have both at least one opening and at least one extension on the same side of the two opposite sides of a panel.

In an embodiment, the extension forms a first contact surface and an edge of the opening forms a second contact surface, wherein the first and second contact surface engage when the first panel and second panel are moved away from each other in circumferential direction of the circumferential wall.

This contact is for example, advantageous in storage constructions for storing a liquid, such as water, or bulk goods, such as grain, potato’s etc. The gravity forcing acting on the liquid or bulk goods results in a force pressing the panels away from each other in the circumferential direction. This movement of the panels is prevented by the engagement of the panels between the first contact surface and the second contact surface.

In an embodiment, each panel of the plurality of interconnected panels comprises at least one extension and/or at least one opening that cooperates with an opening and /or extension of an adjacent panel of the plurality of interconnected panels. For example, each panel comprises at a first side at least one extension and/or at least one opening that cooperates with an opening and/or extension of a panel adjacent to the first side of the respective panel, and at a second side opposite to the first side at least one extension and/or at least one opening that cooperates with an opening and/or extension of a panel adjacent to the second side of the respective panel.

In an embodiment, each extension is integrally formed in the respective panel and bent into a hook shape that extends through the associated opening. This way, one could construct a storage construction out of said panels without the use of other elements which is advantageous in case of limited resources. Certain elements, for example rivets, however, may improve the strength of the storage construction.

In an embodiment, the first panel comprises three or more extensions at one side at different height, wherein a spacing between adjacent extensions of the three or more extensions decreases towards a bottom of the storage construction.

This way, the storage construction can hold more force in the lower part of the storage construction where the force is greater than the upper part of the storage construction due to the forces resulting from that what is stored. For example, the distance between the two highest extensions may be 220 mm and the distance between the two lowest extensions may be 125 mm. As a result, the usage of materials for this construction is more efficient and effective, hence more economical and durable.

In an embodiment, a panel comprises at least two extensions at one side of the first panel, wherein the area of the contact surface of a first extension with its adjacent panel is larger than the area of the contract surface of a second extension with the adjacent panel if the first extension is closer to the ground.

In an embodiment, the first panel comprises two opposite sides with extensions and the second panel comprises two opposite sides with openings. It is possible to adjust the size and shape between the panels comprising extensions and the panels comprising openings for optimal strength.

As an alternative, in an embodiment, the first panel and the second panel both comprise two opposite sides wherein the first side comprises openings and the second side comprises extensions. This way, any amount of panels can be used, regardless whether this amount is even or odd. Furthermore, this allows for a storage construction to be made out of one type of panel, simplifying the production process.

In an embodiment, an unfolding prevention element is provided to prevent unfolding of the hook shape of the extension. This feature prevents unfolding of the extensions for a certain range of forces, allowing the storage construction to withstand forces where the storage construction without the unfolding prevention element would fail. This element can be for example a nail or a rivet or a hairpin-shaped element or a bold-nut combination or another suitable element. One, two, three, or more unfolding prevention elements can be used for an extension to prevent unfolding.

In a further embodiment, the unfolding prevention element extends through aligned holes in the first panel and the second panel.

In an embodiment, the openings are formed to allow movement of the first panel and second panel with respect to each other in a circumferential direction of the circumferential wall over a range of movement. This range of movement includes a position in which the first contact surface and the second contact surface engage each other without exerting a shear force on the unfolding prevention element.

Hereto the opening may have a specific shape for example: a slit shape or a slot shape extending in the circumferential direction to allow relative movement between the first and the second panel in the circumferential direction.

The unfolding prevention element may not be in contact with the second panel. This can be achieved for example, by having a bigger opening in the second panel than the openings in the first panel and extension. The unfolding prevention element not being in contact with the second panel prevents that shear forces are exerted on the unfolding prevention element. If the unfolding prevention element is only in contact with the first panel and its extension, it still prevents the extension from unfolding. The openings may, for example have a length between 50 mm and 4 mm and a width between 10 mm and 1 mm. For example an opening of length 15 mm and width 4.2 mm or an opening of length 8 mm and width of 4,2 mm. The 5 openings may have different dimensions depending on the location of the opening. For example, the openings on the first panel and its extension may be 15 mm in length and 4.2 mm in width while the opening on the second panel may be 8 mm in length and 4.2 mm in width.

In an embodiment, the opening in the extension is located at a position at most at 50% of the length of the extension from a free end of the extension. For example, 40%. This way, the tensile force on the unfolding prevention element is relatively low, which allows a bigger pressure on the construction before the unfolding prevention element fails.

In an embodiment the panels are made out of plastic, or metal. For example, steel or an alloy containing steel or the like.

In an embodiment the modular storage construction comprises a liner element attached to the circumferential wall to form a storage space for storing liquids and/or bulk goods. The liner element may be attached over the whole circumference of the storage construction, this way most of the volume of the storage construction can be used. This attachment is for example done by attaching a ring over the circumference wherein the liner element is fixed between the ring and the circumference. Attachment using rigid bodies for example, bolts, rivets or other suitable means for the attachment. Another possibility to attach the liner element to the storage construction is by making recesses or openings in the panels which are made to receive the liner element or means far attaching the liner element.

The liner element may be embodied as a liquid tight flexible sheet assembly, for example comprising a bottom sheet and a circumferential wall sheet, to form a liquid tight storage space supported by the circumferential wall. If the storage construction is used for storing bulk goods, the liner element may be made from a mesh net, fabric or similar structure having smaller holes than the size of the respective bulk goods to be stored in the storage construction.

The invention further provides a kit for constructing a modular storage construction comprising: a plurality of interconnectable panels to form a standing circumferential wall of the storage construction,

wherein the plurality of interconnected panels comprise at least a first panel having an extension and a second panel having an opening that may cooperate with the extension of the first panel to form a connection, wherein the extension is integrally formed in the panel and is bendable into a hook shape that may extend through the opening.

Since these panels can be stacked on top of each other, the space required to transport the kit is limited compared to a conventional storage construction. This limits the resources required to construct the storage construction, even more so in locations that are difficult to reach.

In an embodiment the kit comprises one or more unfolding prevention elements configured to prevent unfolding of the hook shape of the extension.

In an embodiment the kit comprises a liner element to form a storage space for storing liquids and/or bulk goods, wherein the liner element is attachable to the plurality of interconnected panels. For example attachable to an upper side of the circumferential wall formed by the plurality of interconnectable panels.

The invention further provides a use of a kit for constructing a modular storage construction, the use comprising the steps of: - bending the extension of the first panel into the hook shape, - placing the extension through the opening of the second panel to form a connection between the first panel and the second panel, and - forming a standing circumferential wall of the plurality of interconnectable panels.

In an embodiment, the kit comprises one or more unfolding prevention elements configured to prevent unfolding of the hook shape of the extension, and the use comprises the step of arranging the one or more unfolding prevention elements on the hook shaped extensions to prevent unfolding thereof.

In an embodiment, the kit comprises a liner element, and the use comprises the step of attaching the liner element to the circumferential wall to create a storage space.

Further characteristics and advantages of the invention will now be elucidated by a description of embodiments of the invention, with reference to the accompanying drawings in which:

Throughout the figures, the same reference symbols are used to refer to the corresponding components or to components which have a corresponding function.

Fig. 1 shows an embodiment of the modular storage construction 10 according to the invention comprising a standing circumferential wall 11 and a liner element 100 attached to the circumferential wall 11. The liner element 100 is made from liquid tight and flexible material, such as plastic sheet. The liner element 100 is a liquid tight flexible sheet assembly comprising a bottom sheet 101 and a circumferential wall sheet 102 to form a liquid tight container supported by the circumferential wall 11.

The dimensions of the liner element 100 may be bigger than the dimensions of the circumference wall such that the liner element may rest on the ground and on the circumference wall.

When the storage construction is used for the storage of bulk goods, such as grain and potatoes, the liner element may also be made of water permeable structures, such as a net, a mesh or a fabric.

A plurality of interconnected panels 1A, 1B form a standing circumferential wall. The plurality ofinterconnected panels 1A, 1B comprises, alternately, first panels 1A having extensions and second panels 1B having openings that cooperate with the extensions of the first panels 1A to form a connection (not shown). The extension is integrally formed in the first panel 1A and bent into a hook shape that extends through the opening (not shown). The liner element 100 is fixed on the upper edge of the circumferential wall. The material inside the liner element 100 pushes the panels 1 outwards. The connections (not visible in this figure) prevent the panels 1 from moving outwards, resulting in a stable storage construction. The construction also works for other materials both liquid and non-liquid, for example bulk goods,

or a combination of the two. The liner element100 can be fixated on the circumferential wall by any means suitable for fixating the liner element 100, for example by using nuts and bolts or by rivets and/or sandwiching the edge of the liner element 100 between one or more clamp elements and the circumferential wall 11.

Fig. 2A shows a first panel 1A of the storage construction 10 of Figure 1. This first panel 1A comprises two opposite sides, wherein each side is provided with multiple extensions 2. The distance DE between two adjacent extensions 2 on the same side is larger at the top of the first panel 1A than it is at the bottom of the first panel 1A. The width WE of all extensions 2 which is perpendicular to the length LE of the extension 2 is constant on this first panel 1A. It is possible to have a larger width WE for extensions 2 closer to the ground.

Fig. 2B shows an extension 2 in more detail.

Fig. 2A and Fig. 2B show four holes 21, 22 for each extension 2 in which a unfolding prevention element (see Fig. 4B) can be placed to prevent the extension 2 from unfolding.

The panel 1A comprises two holes, a first hole 21 and a second hole 22. After bending of the extension, the first hole(s) 21 are aligned with the second hole(s) 22 as can be seen in Fig. 4B. Holes 21 are placed at 40% of the length LE of the extension 2 from the free end of the extension 2. Both Fig. 3A and Fig. 3B also show a rounding R at the connecting area of the first panel 1A with an extension 2. A recess 30 for attachment of a liner element (not shown) is shown at the upper side of the first panel 1A.

Fig. 3A shows a second panel 1B of the storage construction 10 of Figure 1. This second panel 1B comprises multiple openings 3 arranged along opposite sides of the panel. The distance DH between two adjacent openings 3 on the same side is larger at the top of the second panel 1B than it is at the bottom of the panel 1B. The height HH of all openings 3 is constant on this second panel 1B. It is possible to have a larger height HH for openings 3 closer to the ground.

Fig. 3B shows an opening 3 in more detail.

Both Fig. 3A and Fig. 3B show two holes 12 for each opening 3 in which a unfolding prevention element can be placed to prevent extension(s) from unfolding wherein the unfolding prevention element is not in contact with the second panel 1B (see Fig. 4B).

Fig. 4A shows a schematic cross-section of a connection of an embodiment of the storage construction. An extension 2 of a first panel 1A is bent through an opening 3 of an adjacent second panel 1B. The extension 2 has a hook shape. In this figure, the extension 2 has a first contact surface 15 and the opening 3 of the second panel 1B has a second contact surface 25. The first contact surface 15 and the second contact surface 25 engage each other when the first panel 1A and the second panel 1B are moved away from each other in the circumferential direction CD. This engagement between the first contact surface 15 and the second contact surface 25 prevents further movement of the first panel 1A and the second panel 1B away from each other in the circumferential direction CD.

Fig. 4B shows a schematic cross-section of a connection of an embodiment of the storage construction. In this connection, an unfolding prevention element 30 is arranged through holes 21, 22 of the first panel 1A and hole 12 of the second panel 1B. In this example this is a rivet. A nail, a bold-nut combination or other elements suitable for prevention of unfolding can also be used. The holes 21, 22 in the extension 2 of the first panel 1A are more narrow in the circumferential direction than the hole 12 corresponding to the opening 3 of the second panel 1B. The rivet may rest only on the first panel 1A and/or its extension 2 perpendicular to the holes 21, 22 of the panel 1A comprising the extension 2. In this embodiment, the unfolding prevention element 30 is movable in the holes 21 and 22 in the circumferential direction to allow the unfolding prevention element 30 to be in a position in which the first contact surface and the second contact surface engage each other without exerting a shear force on the unfolding prevention element 30. This has the advantage that the unfolding prevention element 30 will not be subject to a shear force and is only subject to tensile force to prevent unfolding of the hook shaped extension 2, while the forces in circumferential direction CD will act between the first contact surface 15 and the second contact surface 25. This results in a strong connection with a simple construction.
