The present disclosure relates to a structural element, designed to form different types of structures, in particular to be used as a toy building block.
Building blocks are popular toys for children that allow to form various types of structures, which may resemble realistic structures such as houses, blocks or walls.
In particular, there are known brick-shaped building blocks. Such toys are typically made of cardboard, from a blank having pre-formed bending lines to be folded to form a solid which resembles the brick. Such blanks may have various protrusions and/or openings to facilitate the forming process. They may also be joined by means of additional coupling elements, adapted to protrude through appropriate openings in the structural elements.
One drawback of the present solutions is that the cardboard blanks used for forming structural elements have complicated shapes and there is a limited range of element shapes which may be formed therefrom. Moreover, not all are suitable for use to form toys, the assembly of which should be relatively easy for the user.
There is a need to provide an alternative form of a structural element, in particular for forming building blocks, to allow forming various blocks having different shapes, which will be simple to assembly and use and which will allow constructing structures having a reasonably high strength.

The structural element is presented by means of example embodiments on a drawing, wherein:
The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention.
The structural element 100 has side walls 110 and an inner partition 120 abutting the side walls. Preferably, the inner partition abuts the inner surface of all the side walls, preferably at a right angle. Therefore, the partition 120 is located in a plane which is not parallel to planes of the sidewalls—but is perpendicular to the planes of the sidewalls 110.
The side walls are formed by bending at least one side wall blank 111, such that the at least one side wall blank forms, along its side edge, a contour of the side wall 110. At the sides of the side wall blank there are located flaps 112, 113, which have a height h lower than a height H of the blank in a main part of the side wall. After assembling the side wall blank 111, the flaps 112, 113 abut the flaps of this blank or flaps of another blank, together with which they form the side wall.
The flaps 112, 114 are bent along lines 115 that are perpendicular to the side edge of the blank, such that two blanks 111 assembled with each other have side edges parallel with respect to each other.
In case of the element 100 presented in
The inner partition 120 is formed by bending a partition blank 121, which comprises a main area 122 and flaps 123, 124. The main area 122 has an envelope of a shape corresponding to the inner contour of a cross-section of the structural element, such that in the assembled element 100, the edges of the main area 122 abut the inner surfaces of the side wall 110. On the flaps 123, 124 there are located notches 125, 126, which in the assembled element 100 embrace the abutting flaps 112, 113 to hold them in such assembled position in order to maintain the integrity of the structural element. The flaps 123, 124 have a height h2 not greater than a height h1 of the flaps 112, 113, such as not to protrude beyond the contour of the structural element.
In the inner partition 120 there may be at least one opening 127, for decreasing a weight of the partition.
Preferably, the inner partition is positioned in the middle of the height H1 of the structural element 100.
The element of such type is reasonably simple to be assembled, does not require using glue nor staples and holds rigidity in all directions.
Moreover, in the side wall blank 111, on each of the sides, which is to abut the side of a neighboring element in order to be coupled to it, there are located notches 114, which allow the structural elements to be coupled to each other by means of the coupling elements 10 presented in
The coupling element 10 is formed from a blank 11, which has on its surface 112 a central linear notch 14, divided by a bending line 13 which is perpendicular to it. After assembling the blank along the bending line 13, the notch 14 extends from the edge towards the inside of the coupling element.
The structural elements may be assembled with each other, as presented in
One or more notches 114 may be located along each side wall, depending on the desired structural strength of the coupling of the neighboring elements.

Flaps 212, 213 are bent along bending lines 215, which are not perpendicular with respect to a side edge of a blank 211, such that the blanks 211, when brought together with flaps 212, 213, have their side edges slanted with respect to each other, according to the desired radius of the bending of the corner.
In this embodiment, a main area 222 of the partition has bending lines 228 along which it is bent, such as to fill an inner space between the side walls.
Therefore, the partition 220 is located in a plane which is not parallel to planes of the sidewalls—it is perpendicular to the planes of some sidewalls and slanted with respect to the planes of other sidewalls.
The structural elements are preferably made of cardboard. It is an environmental friendly material, which may be recycled and is easily available. It is easily formable and not expensive. For example, the structural elements can be made of a three-layer or a five-layer corrugated cardboard, depending on the strength requirements of a particular element. The partition and the side walls may be made of the same material. Alternatively, the partition may be made of a different material than the side walls.

Each of the flaps 520A, 520B comprise respectively two notches 525A, 526A and 525B, 526B. After assembling of the structural element, the flaps 520A and 520B abut each other. The elements 512, 513 of the first partition, which is located in the notches 525A, 525B, embrace the flaps in such a way as to maintain them adjacent to each other. Similarly, the elements 514, 515 of the second partition, which is located in the notches 526A, 526B, embrace the flaps in such a way as to maintain them adjacent to each other. The elements 512-515 comprise respectively notches 516-519, each comprising a flat section (545-548) which abuts one of the flaps 520A, 520B. Additionally, adjacent to the flat section of each notch 516-519, there is located respectively a protrusion 531-534, which in the assembled element passes through one of openings 534A, 535B located in the flap 520B, additionally stiffening the structure of the structural element. Preferably, the protrusions 531, 532 pass through the openings 534A and 534B, wherein the protrusions 533, 534 pass through the openings 535A, 535B, wherein the protrusions 532, 534 enter into the openings from the side of the flap 520A, and the protrusions 531, 533 enter the openings from the side of the flap 520B. In this aspect, the partition formed by the abutting elements 512, 513 is located in a plane which is perpendicular to the planes of the sidewalls 510.
In the blank presented in
All of the presented embodiments share the following common essential features. These embodiments relate to a structural element, formed from at least one blank, wherein the structural element comprises side walls and at least one partition located inside the element. The partition extends between at least two side walls, such that it increases the strength of the structural element from the inside. Moreover, the element comprises at least one pair of flaps, wherein each flap in the pair of flaps is formed by an edge part of the at least one blank, which is bent inwards the structural element. The flaps in the pair are adjacent to each other and the partition is coupled with the flaps such as to maintain the flaps adjacent to each other and thus to provide integrity of the outer envelope of the structural element. Therefore, the coupling of an outer plane of the envelope with the internal partition, which is formed in this structural element, provides high strength of the element against compression from different sides and allows to create various kinds of structures therefrom. The structural elements presented herein in different embodiments may be arranged into sets dedicated for forming specified structures or may be arranged into general sets for forming structures according to user's designs. All elements in such set have notches formed in the side walls along sides of the structural element, such that they may be coupled with each other by means of universal coupling elements, that fit for coupling any two elements with each other.
