Description

[0001] Set of blocks

[0002] Field of the Invention

[0003] The subject of the invention is a set of blocks formed by folding cut-outs along their dividing lines of creasing, perforation, perforated creasing, or notching, thereby creating three-dimensional blocks. The set of blocks also includes overlays and / or accessories that match the blocks, as well as a repair kit.

[0004] Background of the Invention

[0005] Sets of blocks made of corrugated cardboard or paperboard are toys constituting a collection of elements cut from sheet materials, preferably using die-cutting technology on manual or automatic presses with flat or rotary dies.

[0006] Such blocks are adapted for self-assembly by a child and / or adults. After assembly, the blocks take on a three-dimensional form.

[0007] State of the Art

[0008] Known from the state of the art are blocks made of corrugated cardboard, formed from cutouts into a three-dimensional shape by folding their segments, connected to each other by inserting edge protrusions into matching openings. Each assembled block has a protrusion that is placed in a recess accessible from the bottom base of the block.

[0009] Summary of the Invention

[0010] The object of the present solution is to propose a set of blocks for self-assembly that allows for the creation of an exceptionally large range of construction variants distinguished by their functional values, while being made of relatively inexpensive materials such as corrugated cardboard or paperboard. Another object of the present solution is to propose a solution that encourages the child and / or guardian to make permanent changes to the elements of the set, such as: drawing, painting, covering the surfaces, perforating, cutting, or permanently joining the toy elements with each other or with other objects made by the child.

[0011] This object has been achieved by the set of blocks according to the present invention.

[0012] The subject of the invention is a set of blocks formed by folding flat cut-outs along their dividing lines of creasing, perforation, perforated creasing, or notching, comprising blocks consisting of a body and at least one insert situated inside the body, the blocks have side slots along the entire length of the sections connecting the side walls of the formed body, and have a bottom slot along the length of the sections surrounding the middle wall of the basic insert, which is situated horizontally in the block's body. The side walls of this insert are located almost vertically, above and to the sides of its middle wall.

[0013] In the block according to the invention, the basic insert located inside the block's body divides this interior with its horizontally positioned middle wall into a chamber closed on all sides and a recess below, accessible from the bottom. This allows for connection with other blocks by placing it over the upper, narrowed part of the blocks below. For a stronger connection of the blocks, the depth of the recess can be increased, forcing an extension of the notches on the side walls, which are an extension of the top slot.

[0014] The blocks included in the set, as well as objects made from them, are characterized by relatively high resistance to static loads. This is mainly due to their basic inserts, made of a much stiffer material, for example, five-layer corrugated cardboard. According to the invention, a single-segment basic insert is embedded in the body of a single-segment block, and a two-segment basic insert is embedded in the body of a two-segment block. The number of segments in the basic insert corresponds to the number of segments in the body. The nearly vertically positioned side walls of these inserts bear the weight of the blocks located above and the weight of objects placed on the blocks. Basic inserts may have a greater number of walls to further strengthen the blocks. These walls may, for example, be an extension of one of the side walls by another wall located horizontally at the top of the chamber and containing a centrally located slot, and by another, which is its second, vertical support. Preferably, the basic inserts are made of a material with higher stiffness than the body - for example, from cardboard with more layers or paperboard with a higher grammage. In the blocks forming structures, according to the invention, the weight of successive layers of blocks is mainly transferred by the rigid side walls of the basic inserts, separated in successive layers by the horizontally positioned top walls of the block bodies. The exception is the lowest layer of blocks (on the floor). In the blocks forming it, the nearly vertical side walls of their basic inserts rest in their locking step zones on the edges of trapezoidal protrusions. The entire load resulting from the blocks above or a child additionally situated on them rests here on the trapezoidal protrusions, side walls, and shaped projections, which, like the entire block body, are made of a material with lower mechanical strength. Therefore, preferably according to the invention, a foundation insert has been proposed for these bottom blocks. Its use in the block's body further increases the structure's strength. The very rigid foundation inserts act as supports for the vertically positioned side walls of the basic inserts, transferring the weight of the structure directly to the ground on which the structure is placed. Hence, a foundation insert is placed in the body under the basic insert. The foundation inserts can be cut from both cardboard and a wood-like material, or they can be a wooden plate filling the recess. It can also be an element with similar geometric features made of polymers. Thanks to the foundation inserts in the set of blocks according to the invention, an additional and significant increase in resistance to static and dynamic loads is achieved.

[0015] The block according to the invention is a single-segment block, a two-segment block, or a multi-segment block. The blocks consist of segments. Two- and multi-segment blocks are a horizontally extended form of the single-segment block, doubled or multiplied, which can consist of ten or even more segments. The multi-segment blocks are then longer and have more top slots defining the boundaries between segments. Additionally, the basic inserts of multi-segment blocks can be equipped with two or more openings.

[0016] According to the invention, the two-segment foundation insert has the form of a spiral with a rectangular outline, while the single-segment foundation insert has the form of a spiral with a square outline.

[0017] The body of the single-segment block has the form of a truncated pyramid with square, parallel bases, in which all its side walls are trapezoids tapering upwards, the surface of which is set at the same angle to the top wall. In turn, the body of a two-segment or multi-segment block has the form of a solid with rectangular, parallel bases, in which all side walls are trapezoids tapering upwards, the surface of which is set at the same angle to the top wall. According to the invention, each of the longer bases of the trapezoids defining the side walls connects to the longer bases of the trapezoids forming the protrusions, which, after being folded, stiffen the lower edges of the block body. The oblique sides of two opposite trapezoids with shorter base sections connect to the shaped projections. The shaped projections, similarly to the basic inserts after the block is assembled, prevent it from returning to a flat form and increase the structure's resistance to loads.

[0018] According to the invention, the top wall of the body of a two-segment or multi-segment block has at least one top slot. This slot defines the boundaries between the segments.

[0019] Preferably, the two-segment insert has a middle wall in the shape of a rectangle with a central opening and two side walls in the shape of an isosceles trapezoid, connected by their longer base to the longer side of the middle wall, wherein the length of the longer base of the side wall is greater than the length of the longer side of the middle wall. The longer base of the side wall has locking steps at its ends, and each side wall has a perpendicular central notch on the side of its shorter base. In turn, the single-segment insert has a middle wall in the shape of a square with a central opening and two alternating side walls in the shape of an isosceles trapezoid, connected by their longer base to the opposite sides of the middle wall, wherein the length of the longer base of the side wall is greater than the length of the side of the middle wall. The longer base of the side wall has locking steps at its ends.

[0020] The locking steps according to the invention prevent the basic insert from sliding out (falling out) of the block body. This is achieved because the resilient protrusions snap into the locking steps and block the basic insert.

[0021] The protrusions according to the invention perform the following functions:

[0022] - they stiffen the lower edges of the block;

[0023] - they have a spring-like effect, compressing the block below around its perimeter, which increases the connection strength between the blocks.

[0024] According to the invention, there are triangular gaps between the blocks forming horizontal rows. The cross-section of the gap has the form of an isosceles triangle, whose arms converge downwards, and the base at the top has a dimension corresponding to a multiple of the thickness of the material from which the block body is made, preferably 4 to 10 times. The set of blocks according to the invention includes at least one overlay and / or at least one accessory. The overlay has a multi-layered top wall with a rectangular outline, the length and width of which are equal to a single or multiple of the section defining the bottom base of the single-segment block's solid, and it covers the upper surfaces of objects made from the blocks that are subject to increased static or dynamic loads. The overlays are for installation on selected areas of objects made from the blocks that are subject to increased static or dynamic loads. The overlays placed on the blocks act as thresholds, sills, etc., significantly strengthening the top bases of the blocks weakened by the top slots. The overlays reinforce these zones with several additional layers, increasing resistance to static and dynamic loads. Like the blocks, the overlays have a length of one or more segments. Their width can also span more than one block segment.

[0025] A very important part of the set is a potentially unlimited range of accessories equipped with protrusions for installation in the many functionally useful slots located in the blocks and between the blocks. The blocks and accessories can be of different sizes, allowing for the construction of objects that can accommodate children and even adults, or intended for creating structures for larger or smaller dolls. With the same bottom base dimensions and similar top base dimensions, the blocks can have different heights. For their compatibility, it is preferable that the height of the tallest block corresponds to the height of stacks / pillars made of several blocks of smaller heights.

[0026] Hence, the accessory according to the invention has at least one protrusion, preferably hookshaped and / or straight, wherein the accessory can also be a flat extension of the protrusion constituting a hook or containing an opening or another mounting element. Preferably, at least one accessory protrusion has geometric features enabling its installation in a side slot and / or a bottom slot and / or a top slot. The accessory imitates a product of technology or a creation of nature. If the accessory has at least two hook-shaped protrusions, they should ultimately both be inserted into the vertical, triangular gaps between the walls of two blocks. In turn, when the accessory has at least one straight protrusion, it can be installed in the bottom slot, the top slot, or the side slot. The protrusions can also be separate mounting elements, not permanently connected to the objects installed on the blocks. In that case, they can be independently installed in the gap between blocks, in any slot of a block, or in a slot of an object hung on the block structure. The resistance of the blocks to static loads is mainly due to their inserts made of a much thicker and stiffer material. Despite the high stiffness of this material, assembling the inserts is easy because their construction is very simple.

[0027] The blocks and accessories can be made of corrugated cardboard with a different number of layers, paperboard, or thicker paper. These materials can also be laminates with polymer films. It is also possible to make the blocks from polymers, such as polypropylene.

[0028] The set of blocks and accessories according to the invention is distinguished by exceptional functional values, thanks to a wide range of accessories equipped with protrusions, which can be installed on / in objects made from the blocks. The set of blocks and accessories is also distinguished by the fact that the blocks themselves, as well as objects made from them, have increased resistance to loads and surpass other sets of blocks made from similar materials in this respect. This is determined both by the construction of the block's body itself, and its basic inserts, its foundation inserts, and the overlays that significantly strengthen the top bases of the blocks. Thanks to this, a child can stand or sit on the blocks without any possible deformation of their top walls. In objects made from the blocks, the overlays serve as upper surfaces subject to increased load, e.g., door thresholds, sills, seats, beds, stair treads, countertops, vehicle loading surfaces, and other solutions.

[0029] The set of blocks also includes a repair kit, consisting of self-adhesive materials and glues, sheets of corrugated cardboard, paperboard, and paper, as well as tools for their processing. It facilitates undertaking the activities mentioned in another part of the documentation and is an aid in conducting educational activities consisting of repairing what has been damaged.

[0069] Detailed Description of the Invention This description presents exemplary embodiments of a set of blocks formed by folding cutouts along their dividing lines of creasing, perforation, perforated creasing, or notching, thereby creating blocks with matching accessories and / or overlays. They can be made of corrugated cardboard, paperboard, thicker paper, polymer materials, including polypropylene, as well as materials based on a combination of paper and polymer. Preferably, the single-segment block has a base side dimension from 1 cm to 50 cm.

[0070] Fig. la shows a convergent perspective view of an inverted two-segment body 1 and an inverted two-segment basic insert 2 above it before its installation in the body 1 of the two- segment block 3. Fig. lb shows a view of the two-segment block 3 in an inverted position with the two-segment basic insert 2 installed in the two-segment body 1. After folding the cut-out of the two-segment body 1, side slots 13.1 are formed along the entire length of the sections connecting the side walls 1.2, 1.3 of the formed two-segment body, and a bottom slot 13.2 is formed, preferably along the entire length of the four sections surrounding the middle wall 2.1 of the two-segment basic insert 2 embedded in the two-segment body 1. In turn, Fig. 1c shows the two-segment body 1 of the two-segment block 3. The body 1 of the two-segment block 3 or multi-segment block has the form of a solid with rectangular, parallel bases, in which all side walls 1.2, 1.3 are trapezoids tapering upwards, the surface of which is set at the same angle to the top wall 1.1. The two-segment body 1 has a top wall 1.1 divided into two parts by a top slot 1.1.1, two smaller side walls 1.2, and two larger side walls 1.3. Along the entire length of the sections connecting the side walls 1.2, 1.3 of the assembled body 1, the two-segment block 3 has side slots 13.1. The top wall 1.1 of the two-segment block 1 is in the shape of a rectangle with a longer side length twice that of the shorter side length. The two smaller side walls 1.2 are in the shape of a trapezoid. Each smaller side wall 1.2 connects by its shorter base to the shorter side of the top wall 1.1. The two larger side walls 1.3 are also in the shape of a trapezoid. Each larger side wall 1.3 connects by its shorter base to the longer side of the top wall 1.1. The top wall 1.1 has a top slot 1.1.1 located centrally and parallel to its shorter sides, extended on both sides onto the larger side walls 1.3.

[0071] Fig. Id shows the inverted body 1 of the two-segment block 3. This figure shows that each smaller side wall 1.2 has a protrusion 1.2.1 in the shape of a trapezoid connected by its longer base to the longer base of the smaller side wall 1.2, and shaped projections 1.2.2 connected to the arms of the smaller side wall 1.2. Each larger side wall 1.3 has a protrusion 1.3.1 in the shape of a trapezoid connected by its longer base to the longer base of the larger side wall 1.3. Fig. le shows the cut-out layout of the two-segment body 1, according to the invention, which is folded according to the lines marked on it. The two-segment body 1 is formed by folding the smaller side walls 1.2 in the same direction along the sides of the top wall 1.1, and then their shaped projections 1.2.2, so that they are located on the inner side of the folded two-segment body 1. Then, the larger side walls 1.3 are folded in the same direction. The protrusions 1.2.1 of the smaller side walls 1.2 and the protrusions 1.3.1 of the larger side walls 1.3 are folded inwards of the assembled two-segment body 1.

[0072] The two-segment basic insert 2 is shown in Fig. 2a. The two-segment basic insert 2 has a middle wall 2.1 in the shape of a rectangle with a central opening 2.1.1 and two side walls 2.2 in the shape of an isosceles trapezoid connected by their longer base to the longer side of the middle wall 2.1. The length of the longer base of the side wall 2.2 is greater than the length of the longer side of the middle wall 2.1. The longer base of the side wall 2.2 has locking steps 2.2.1 at its ends. The two-segment basic insert 2 has four locking steps 2.2.1. Each side wall 2.2 has a perpendicular central notch 2.2.2 on the side of its shorter base. Fig. 2b presents the cut-out layout of the basic insert 2 for the two-segment block 3, which is folded according to the lines marked on it. The two-segment basic insert 2 is formed by folding the side walls 2.2 in the same direction along the longer base.

[0073] In turn, Fig. 3a shows a convergent perspective view of a single-segment block 7 with the single-segment basic insert 6 extended upwards. The single-segment block 7 consists of a single-segment body 5 and a single-segment basic insert 6 inserted into the single-segment body 5. The body 5 of the single-segment block 7 has the form of a truncated pyramid with square, parallel bases. According to the invention, the single-segment body 5 has a top wall 5.1 in the shape of a square with a side length equal to the length of the shorter side of the top wall 1.1 of the two-segment body 5, and four side walls 5.2 in the shape of a trapezoid, preferably isosceles - this is shown in Fig. 3b. After folding the cut-out of the single-segment body 5, as presented in Fig. 3c, four side slots 13.1 are formed along the entire length of the sections connecting the side walls 5.2 of the formed single-segment body 5. Each of the four side walls 5.2 of the single-segment body 5 connects by its shorter base to the side of the top wall 5.1. Each side wall 5.2 has a protrusion 5.2.1 in the shape of a trapezoid, preferably isosceles, connected by its longer base to the longer base of the side wall 5.2. Furthermore, two alternating side walls 5.2 have shaped projections 5.2.2 connected to the arms of these side walls 5.2 of the single-segment body 5. Fig. 3d shows the cut-out layout of the body 5 of the single-segment block 7, according to the invention, which is folded according to the lines marked on it. The single-segment body 5 is formed by folding the side walls 5.2 in the same direction along the sides of the top wall 5.1. Their shaped projections 5.2.2 are also folded in the same direction along the arms of the side walls 5.2, so that they are located on the inner side of the folded single-segment body 5. Then, the protrusions 5.2.1 of the side walls 5.2 are folded inwards of the assembled single-segment body 5.

[0074] In turn, Fig. 4a shows the single-segment basic insert 6 for the single-segment body 5 of the single-segment block 7. The single-segment basic insert 6 has a middle wall 6.1 in the shape of a square with a central opening 6.1.1 and two alternating side walls 6.2 in the shape of a trapezoid, preferably isosceles, connected by their longer base to the opposite sides of the top wall 6.1. The length of the longer base of the side wall 6.2 is greater than the length of the side of the middle wall 6.1. The longer base of the side wall 6.2 has locking steps 6.2.1 at its ends. The single-segment basic insert 6 has four locking steps 6.2.1. Fig. 4b shows the cut-out layout of the basic insert 6 for the single-segment block 7, which is folded according to the lines marked on it. The single-segment basic insert 6 is formed by folding the side walls 6.2 in the same direction along the longer base.

[0075] In the interior of the two-segment body 1 of the two-segment block 3 shown in Fig. 5a, the two-segment basic insert 2 divides this interior with its horizontally positioned middle wall 2.1 into a chamber 1.4 closed on all sides and a recess 1.5 below, accessible from the bottom. The recess 1.5 allows for connecting one block with another by placing the two-segment block 3 from the side of the recess 1.5 onto the upper, narrowed part of the block below.

[0076] Figs. 5a and 5b show the method of placing the two-segment basic insert 2 inside the assembled two-segment body 1 of the two-segment block 3 : a) the side walls 2.2 of the two-segment basic insert 2 are located on the inner side of the larger side walls 1.3 of the two-segment body 1, b) the central notches 2.2.2 of the side walls 2.2 of the two-segment basic insert 2 correspond to the extensions of the top slot 1.1.1 of the top wall 1.1 of the two-segment body 1 located on its larger side walls 1.3, c) the locking steps 2.2.1 of the two-segment basic insert 2 rest on the edges of the shorter bases of the protrusions 1.2.1 of the smaller side walls 1.2 of the two-segment body 1 of the two-segment block 3.

[0077] In turn, Fig. 6a shows a cross-section of the single-segment block 7, in whose single-segment body 5 a single-segment basic insert 6 is placed, which divides this interior with its horizontally positioned middle wall 6.1 into a chamber 5.4 closed on all sides and a recess 5.5 below, accessible from the bottom. The recess 5.5 allows for connection with other blocks by placing the single-segment block 7 from the side of the recess 5.5 onto the upper, narrowed part of the blocks below.

[0078] Furthermore, Figs. 6a and 6b show a cross-section of the single-segment body 5 of the singlesegment block 7 with the single-segment basic insert 6 placed in it. The single-segment basic insert 6 is placed inside the assembled single-segment body 6 in such a way that: a) the side walls 6.2 of the single-segment basic insert 6 are located on the inner side of the side walls 5.2 of the single-segment body 5, b) the locking steps 6.2.1 of the single-segment basic insert 6 rest on the edges of the shorter bases of the protrusions 5.2.1 of the side walls 5.2 of the single-segment body 5.

[0079] According to the invention, inside the two-segment body 1 of the two-segment block 3, in addition to the two-segment basic insert 2, a two-segment foundation insert 4 can also be placed. The two-segment foundation insert 4 has the form of a spiral with a rectangular outline, having shorter sides 4.1 and longer sides 4.2, as shown in Fig. 7. The placement of the two-segment foundation insert 4 and the two-segment basic insert 2 inside the two-segment body 1 is shown in Fig. 8. On the inverted two-segment block 3, it can be seen that the bottom slot 13.2 is covered by the two-segment foundation insert 4 inserted into the two- segment body 1. The remaining slots - the side slots 13.1 and the top slot 1.1.1 in the two- segment body 1 - can be used according to the purpose of the present invention. The outer length of the shorter side 4.1 corresponds approximately to the length of the shorter base of the protrusion 1.2.1 of the smaller side wall 1.2 of the two-segment body 1, and the outer length of the longer side 4.2 corresponds approximately to the length of the shorter base of the protrusion 1.3.1 of the larger side wall 1.3 of the two-segment body 1. The height of the two-segment foundation insert 4 corresponds to the depth of the recess 1.5.

[0080] According to the invention, inside the single-segment body 5 of the single-segment block 7, in addition to the single-segment basic insert 6, a single-segment foundation insert 8 can also be placed. The single-segment foundation insert 8 has the form of a spiral with a square outline, with equal sides 8.1 - a not fully assembled single-segment foundation insert 8 is shown in Fig. 9. The placement of the single-segment foundation insert 8 and the singlesegment basic insert 6 inside the single-segment body 5 of the single-segment block 7 is shown in Fig. 10. It can be seen that in the single-segment block 7, the bottom slot 13.2 is covered by the single-segment foundation insert 8 inserted into the single-segment body 5. The remaining side slots 13.1 in the single-segment body 5 can be used according to the purpose of the present invention. The single-segment foundation insert 8 of the single-segment body 5 of the single-segment block 7 is in the shape of a square, whereby the outer length of the side 8.1 corresponds approximately to the length of the shorter base of the protrusion 5.2.1 of the side wall 5.2 of the single-segment body 5. The height of the singlesegment foundation insert 8 corresponds to the depth of the recess 5.5. Fig. 11 shows the single-segment body 5 of the single-segment block 7 with the single-segment basic insert 6 placed inside it and the single-segment foundation insert 8 placed under it. The arrangement of the two-segment foundation insert 4 in the two-segment body 1 of the two-segment block 3 is the same.

[0081] The cut-out layout of the overlay 9 according to the invention is shown in Fig. 12, while Fig. 13 shows a view of two two-segment blocks with a two-segment overlay 9 placed on them, which in its left part constitutes a cross-section A-A, the line of which is revealed in Fig. 12. As shown in Fig. 12, the overlay 9 has a top wall 9.1 in the shape of a rectangle and two rectangular smaller side walls 9.2 connected to the shorter sides of the top wall 9.1. The overlay 9 also has two rectangular larger side walls 9.3 connected to the longer sides of the top wall 9.1. Each smaller side wall 9.2 has shaped projections 9.2.3 at its shorter sides. Each smaller side wall 9.2 has a first protrusion 9.2.1 in the shape of an isosceles trapezoid connected to it by its longer base, and a second protrusion 9.2.2 in the shape of a right trapezoid connected to the first protrusion 9.2.1 by its longer base. The first larger side wall 9.3 has a first protrusion 9.3.1 in the shape of an isosceles trapezoid connected to it by its longer base and a second shaped protrusion 9.3.2 with a shape similar to a rectangle, whose shorter side has a dimension approximately corresponding to the length of the shorter side of the top wall 9.1. The second larger side wall 9.3 has a first protrusion 9.3.3 in the shape of an isosceles trapezoid connected to it by its longer base and a second protrusion 9.3.4 in the shape of a rectangle connected to the first protrusion 9.3.3 by its longer side. The length of the arms of the second protrusion 9.3.4 corresponds approximately to the length of the shorter side of the top wall 9.1, and on its outer edge, the second protrusion 9.3.4 has a centrally located semicircular cutout 9.3.5. The length of the longer side of the top wall 9.1 is equal to the distance between the axes of the top slots 1.1.1 of the top walls 1.1 of two two-segment blocks 3 touching with the bases of their smaller side walls 1.2. The overlay 9 from Fig. 12 is formed by folding the smaller side walls 9.2 and larger side walls 9.3 in the same direction along the sides of the top wall 9.1. Their shaped projections

[0082] 9.2.3 are also folded in the same direction along the shorter sides of the smaller side walls 9.2 so that they are located on the inner side of the folded overlay 9. Then, the protrusions

[0083] 9.2.1 of the smaller side walls 9.2 and the protrusions 9.3.1 of the larger side walls 9.3 are folded inwards of the assembled overlay 9. Next, on the bottom surface of the top wall 9.1, first the second protrusions 9.2.2 of the smaller side walls 9.2 are placed, then the second shaped protrusion 9.3.2 of the first larger side wall 9.3, and finally the second protrusion

[0084] 9.3.4 with the semicircular cutout 9.3.5 of the second larger side wall 9.3.

[0085] Fig. 13 shows two two-segment blocks 3 touching with the bases of their smaller side walls 1.2, between which there are triangular gaps 13. The cross-section of the gap 13 has the form of an isosceles triangle, whose arms converge downwards, and the base at the top has a dimension corresponding to a multiple of the thickness of the material from which the two- segment body 1 of the two-segment block 3 is made, preferably 4 to 10 times. An overlay 9 is placed on two adjacent two-segment blocks 3. One folded smaller side wall 9.2 of the overlay 9 is inserted into the top slots 1.1.1 of each two-segment block 3, while the folded larger side walls 9.3 adjoin the larger side walls of the two-segment block 3. The top wall

[0086] 9.1 of the overlay 9 connects the two two-segment blocks 3 and strengthens their top walls 1.1. The top wall 9.1 of the overlay 9 has a rectangular shape. In this case, the overlay 9 connects either two single-segment blocks 7 or a single-segment block 7 with a two-segment block 3 or a multiple thereof. If the overlay 9 connects a single-segment block 7 and a two- segment block 3, then the side wall 9.2 of the overlay 9 on one side enters the top slot 1.1.1, and the remaining walls of the overlay 9 adjoin the side walls 1.2, 5.2 of the blocks 3, 7.

[0087] Fig. 14 shows a convergent perspective view of one of many possible examples of an arrangement of blocks with accessories installed in their slots. Four two-segment blocks 3 were used to create it. A third two-segment block 3 was inserted into the top slots 1.1.1 of the two lower two-segment blocks 3. One part of the top wall 1.1 of each of the two lower two- segment blocks 3 was placed in the recess 1.5 of the third two-segment block 3. A fourth two-segment block 3 was placed on the third two-segment block 3. The recess 1.5 of the fourth two-segment block 3 was placed over the third two-segment block 3. The recess 1.5 allows for connection with other blocks by placing it over the upper, narrowed part of the blocks below. An accessory according to the first embodiment in the form of an extended protrusion 10.1 was inserted into one side slot 13.1 of the first two-segment block 3 and into one side slot 13.1 of the second two-segment block 3. An accessory according to the second embodiment in the form of an extended protrusion 10.2 was inserted into two side slots 13.1 of the fourth two-segment block 3, at the analogous larger side wall 1.3 of the two-segment body 1, and an accessory according to the third embodiment in the form of an extended protrusion 10.3 was inserted into two further side slots 13.1 of the fourth two-segment block 3. An accessory according to the first embodiment in the form of an extended protrusion 10.1 was inserted into the bottom slot 13.2 of the fourth block, only imitating a different body part than in the lower blocks 3. In turn, an accessory according to the fourth embodiment was inserted into the top slot 1.1.1 of the fourth two-segment block 3. According to the invention, depending on the decorative elements placed on a given accessory 10.1, 10.2, 10.3, 10.4 or the way the accessory is formed and decorated by the user, the given accessory can perform a different function - for example, according to the example shown in Fig. 14, it can be hands or teeth, ears, eyes, or hair.

[0088] Fig. 15a shows a fifth example of an accessory, which can be a shelf 11. The shelf 11 has two side walls 11.1, which are extended by protrusions 11.2. These protrusions are preferably hook-shaped protrusions. In the wall formed from two-segment blocks 3, shown in Fig. 15b, the shelf 11 is mounted in such a way that the hook-shaped protrusions 11.2 of its side walls 11.1 are located in the triangular gaps 13 between the two-segment blocks 3.

[0089] According to a sixth embodiment, an additional accessory accompanying the blocks 3, 7 can be a box 12. The box 12 is shown in convergent perspective view in Fig. 16a. The box 12 has two twin protrusions 12.2 connected to the longer edge of the rectangular top wall 12.1. These are preferably two straight protrusions.

[0090] Fig. 16b shows a vertical cross-section of a wall made of two-segment blocks 3. The straight protrusions 12.2 of the box 12 are inserted into the bottom slot of one of the blocks.

[0091] Fig. 17 shows a part of a wall made of two-segment blocks 3. Triangular gaps 13 are formed between the smaller side walls 1.2 of adjacent two-segment blocks 3. List of Reference Numerals in the Drawing
