DETAILED DESCRIPTION OF EMBODIMENTS

[0016] The disclosed subject matter pertains to building blocks which are interlockable with like blocks. The building blocks in accordance with an example of the disclosed subject matter are made by injection molding from plastic material. The building blocks can be used for construction of various structures such as furniture items, seen for example in Fig. 10A, stationary structures such as a separation wall, or plant holders seen in Fig. 10B.

[0017] In accordance with the disclosed subject matter, the building blocks are configured to deploy between a disassembled substantially flat configuration and an erected configuration of a generally three dimensional structure.

[0018] The disclosed subject matter allows construction of modular structures comprising a plurality of blocks in accordance with the disclosed subject matter. Thus, for example, a plurality of the building blocks can be used to construct a plant holder and same blocks can be used to construct a table, sofa, armchair, etc.

[0019] Attention is first directed to Figs. 1-2 illustrating a building block generally designated 100 in accordance with one embodiment of the disclosed subject matter. The building block 100 has a hollow, generally parallelepiped configuration (cuboid in this case) and comprises two opposite side walls 110A and 110B, a top wall 120, a bottom wall 125 (seen best in Fig. 1B), constituting a body 105 of the block 100, and two end walls designated as 115A and 115B. The top wall 120 of the block 100 comprises outwardly protruding coupling studs 130 and receiving cavities 140 on the bottom wall 125. The coupling studs 130 are configured to interlock with the receiving cavities 140 of the like block 100. Such interlocking can be seen in figures 11B through 11D. In accordance with this specific example the coupling studs 130 and the respective receiving cavities 140 extend coaxially as best seen in Figs. 1B, 2 and 11D. At least one side wall of the stud 130 is slightly slanted to facilitate removal thereof from the mold and in use, to facilitate interlocking with the cavity 140. The studs 130 are further fitted with outwardly protruding longitudinal element 132 on each face thereof designed to increase friction when received in the receiving cavities 140 and to lock the studs 130 within said cavities 140 in a firmer and stronger manner. It will be appreciated that such outwardly protruding element is an optional feature and other friction increasing/locking elements can be utilized to achieve the same function. The protrusion can thus range in size, i.e. length of the protrusion measured outward from the outer wall of the stud 130, from 0-50mm, from 0-10mm, from 0-3mm depending on the required clamping force. Such protrusions can be configured on any number of faces of the stud. Alternatively, the studs can be free of any such elements.

[0020] The height h of the coupling stud 130 is equal to or less than the depth H of the receiving cavity 140 so as when the two like blocks 100 are interlocked the studs 130 are substantially received within the cavity 130 so as to form a unitary structure comprising the two blocks 100 substantially devoid of any space therebetween. The studs 130 in accordance with this specific example have a rectangular cross section and the cavities 140 have a respective shape each adapted to receive the stud 130. As seen in Fig. 1C, the cavity further comprises a recess in its walls configured for snap engagement of the outwardly protruding element 132 fitted on the studs 130. The exemplified block 100 comprises only four studs 130 with such protrusions 132, disposed at the corners of the top wall 120, however it will be appreciated that in accordance with the disclosed subject matter any number of studs 130 can be fitted with such elements.

[0021] While the current example is directed to a building block 100 comprising two rows of four coupling studs 130 each and respective two rows of four receiving cavities 140 the vast number of possible combinations is envisioned by the presently disclosed subject matter, e.g. block 200 comprising only two studs 230 in each row as seen in Fig. 9 in its flat, disassembled configuration and Figs. 11 in an assembled, configuration fitted over the block 100. It is also to be understood that the modularity of the structures constructed from the blocks is facilitated as seen in Fig. 11. Further, the blocks 100,200 can be interlocked not necessarily when fully coextending but rather one block can be seated over a like block through part of its studs.

[0022] It will be appreciated that the block can have any dimensions desired for the specific design and can be shaped to conform to a particular construction application thus for example rather than having cuboid configuration as seen in Fig. 1A it is appreciated that the building block can have a shape of a pyramid or a triangle cross section. Such shapes are seen for example in Figs 12-14 , where cross sections of the blocks 500, 300, 400, respectively are illustrated where features similar to those of block 100 are identified by same numerals, upped by 400, 200 and 300, respectively and will be discussed herein after.

[0023] The end walls 115A and 115B of the block 100 exemplified in Fig. 1A are detachably attachable to the block's body structure 105. In accordance with this example the end walls 115A and 115B are snap fitted to the open edges of the structure 105 as will be further discussed. It will be appreciated that other solutions can be employed to achieve the same result. Alternatively the one or both of the end walls 115A and 115B can be permanently attached to the body 105.

[0024] The detachment of any one or both of the end walls 115A and 115B can facilitate access into the hollow space formed by the side walls of the structure, e.g. for storage. As best seen in Fig. 1B, the receiving cavities 140 on the bottom wall 125 of the block 100 further comprise apertures 142. Such apertures allow ventilation of the block's 100 interior. It will be appreciated that such apertures 142 are optional. The blocks can be used to build structures for outdoor use. To provide such structures, e.g. a separation wall, with sturdiness and ability to withstand movement due to weather conditions or incidental displacement might be filled with weight increasing material such as sand, stones, liquid, etc. An outer layer of the block at least partially can be covered with a UV-protective layer or such material can be integrated into the block material.

[0025] Turning now to Figs. 3 through 6, a discussion will be provided on the structure and assembly of the building block 100 in accordance with an example of the disclosed subject matter. Fig. 3 illustrates all elements of the building block 100 illustrated in Fig. 1A in its collapsed configuration. Fig. 3 illustrates a polygonal sheet comprised of four integrally formed panels connected to each other through their respective edges by means of an integral hinge 134 (i.e. living hinge which can also be constituted e.g. by a thinned section of the material as seen in Fig. 6 or fold enabling perforations in the material, not shown). The panels correspond to the side walls 110A and 110B, the top wall 120 and the bottom wall 125 which in their folded, erected configuration form the hollow block body 105. Also shown are the two end walls 115A and 115B which are configured for coupling to the polygonal sheet 105 when in its erected folded configuration.

[0026] Fig. 4A provides an illustration of the polygonal sheet illustrating its four panels 110A, 120, 110B, and 125. Seen in a perspective bottom view of the sheet is an inner side of the building block which shows the two working edges T1 and T2 of the polygonal sheet. These edges T1 and T2 are interlockable when the sheet 105 is erected to form the three-dimensional structure seen in Fig. 1A. In accordance with this embodiment the two working ends are configured for snap fitting one within the other. The working edge T1 is associated with the bottom wall 125 while the working edge T2 is associated with the side wall 110A. The working edge T1 is configured with a curved protrusion 127 adapted to be received within a slot 129 provided on the edge T2 and lock therein, e.g. by snap fitting. When the two edges T1 and T2 arc brought together, the integral hinges come into operation to facilitate fold therealong such that the two side walls 110A and 110B are supported over the bottom wall 125 panel and support thereon the top wall panel 120.

[0027] The panels are provided on the bottom side with raised ribs to impart these with rigidity. As seen in this figure raised longitudinal ribs are provided on the side walls 110A, 110B to impart rigidity and strength to the erected structure such that when erected the ribs extend along the axis X (shown in Fig. 1A) thus configured to allow the block to withhold more weight when load is placed thereupon. Further ribs are provided on the bottom side of the top wall and the bottom wall as seen in Fig. 4A. The ribs of these panels are crossed surrounding each of the studs and the receiving cavities thereon, respectively. The outer edges of the top wall panel and the bottom wall panel adjacent the integral hinges are provided with further raised longitudinal ribs 158. In accordance with this example, the ribs 158 are connected to the transverse ribs extending along these panels. These ribs 158 constitute part of a movement preventing mechanism which imparts further characteristics of strength and inhibits unintentional movement and collapse of the side walls under weight/force. The raised ribs 158 are configured for interlocking vis-à-vis the raised rib 155 on the side wall 110A and 110B which extend perpendicularly to the ribs 158 when the block is in its disassembled flat configuration. The end 155A of the rib 155 adjacent the integral hinge 134 is configured with a cut out section forming a shoulder, having dimensions configured to fit over the raised rib 158. The dimensions of the shoulder 155A are such that the height S of the rib 158 and the length L of the cut out section 155A are substantially the same so as for the shoulder to sit over the rib 158 and abut it in the event that force is exerted thereupon. Working configuration of this mechanism is best seen in Fig. 8B illustrating the shoulder 150A sited over the raised rib 158 and supported thereupon.

[0028] With reference to Fig. 5, end walls 115A and 115B will not be described. As indicated hereinbefore, each end wall 115A and 115B is configured for attachment to the open ends of the hollow body 105. The attachment in accordance with the illustrated example is through snap fitting facilitated by a receiving cavity 114 fitted at the edges of the end wall and corresponding protruding curved edges 112 (best seen in Fig. 2B) at the outer ends of the panels 110A, 120, 110B, 125. It will be appreciated that whilst in the described examples the edges 112 are continuous along the ends, other configurations can be employed, such as non continuous edges, staggering edges etc. The side wall is fitted with raised reinforcing ribs 150 disposed at its bottom side 154 and restraining members 152 adjacent its edges. The restraining members 152 are configured to abut the inner side of the hollow body 105 when in the erected configuration so as to impart the structure with further strength.

[0029] Fig. 7A illustrates a plurality of blocks 100 in their disassembled, knocked down configuration stacked one over the other. As can be appreciated from this illustration, the block bodies 105 are stacked one over the other with the sidewalls 115A and 115B arranged therebetween to minimize the space for packing and transportation purposes.

[0030] Figs. 7B and 7C illustrate a stack 1000 of twenty building blocks 100 in a ten layer stack, the building blocks being in their knocked down, unfolded, configuration. The blocks are arranged as follows, allowing minimizing the size of a package for their transport, maximizing the use of the package space (e.g. as illustrated in Fig. 7C): the knocked down block body 105 is placed in the illustrated example face down (i.e. the surface facing outwards when in the erected configuration is facing down, although it will be appreciated that the other face of the block can face downwards) with the panel constituting the functional bottom wall 125 facing the outer end of the stack, seen at the left of the illustration, and the block of a similar configuration is placed adjacent (for the purposes of explanation, same elements of the block are identified using same numerals with added " ' "), however in a turned around, reversed configuration, such that the panel constituting the side wall 110A' is now overlapping the panel 110A, and the panel constituting the functional bottom wall 125' facing the outer, other end of the stack, seen in the right side of the illustration. The two end walls 115A and 115B and 115A' and 115B' arc placed over the intermediate panels constituting the side walls 110B and 110B' of the respective block body. The following in stack layers are arranged in a similar manner. As can be seen in each row the adjacent panels overlap (in this example one panel from each side) and in each column, the adjacent block bodies fully overlap over all four of its panels. As can be appreciated from Fig. 7B and 7C, the height H of the panel comprising the receiving cavity 140, the height h of the coupling stud and the panel it protrudes from and the height of the intermediate panels 110B with the end wall 115 placed the rover as well as the height of the two overlapping side walls 110A and 110A' are substantially equal, thus contributing to the stability of the stack 1000, with all possible gaps filled by the respective elements of the block. Thus, in each row, the two polygonal sheets 100 and 100' partially overlap over the panels 110A and 110A' and in each column, the two polygonal sheets fully overlap in both columns. Thus sheet 100 overlaps like sheet placed over in the same orientation and sheet 100' overlaps like sheet placed over in the same orientation over it.

[0031] It will be appreciated that the blocks can be arranged in a different manner and different stacking configurations are envisioned, mutatis mutandis.

[0032] Turning now to Figs. 12-14, Fig. 12 illustrates a block having a generally trapezoid cross section taken transversely, where the top wall 520 and the bottom wall 525 are parallel, and where the width W of the panel constituting the top wall 520 is broader than that of the bottom wall, having a width w. Fig. 13 illustrates a block 300, having a generally triangular cross section, where the side walls 310 A and 310B are of the same dimensions and wherein the functional wall 321 connecting the side walls comprise a plurality of studs 330 (only one is seen in this view) and a plurality of receiving cavities 340. Fig. 14 illustrates a block 400, similar to the structure of block 100 with the difference that the side walls 410A and 410B are slightly outwardly curved.
