Description
- This application claims benefit of Italian Patent Application serial number TO2004A000578, filed Aug. 31, 2004, which is herein incorporated by reference.
- 1. Field of the Invention
- The present invention relates to a toy building block.
- 2. Description of Related Art
- Widely known are toy building blocks formed by a parallelepiped structure provided with engagement means able to co-operate with complementary engagement means of another block, to obtain the mutual connection of a plurality of blocks whose shape and dimensions are the same or different, to build complex constructions.
- Also known are building blocks in which the parallelepiped structure is internally hollow and the retaining means are provided on some of the faces of the structure. An example of toy block of this kind is described in Belgian patent no. 900609, which illustrates a toy block using permanent magnets to connect the blocks to each other.
- The present invention was developed to provide building blocks with large dimensions, e.g. prismatic blocks in which each side has a length of several centimetres. For example, without limiting in any way the field of application, the present invention could be used to obtain prismatic building blocks whose dimensions are multiples of 40 mm, e.g. 80×80×40 mm or 80×160×40 mm.
- Building blocks of such dimensions would have the drawback of a very large size of the package to be sold, with consequent high transportation costs and the need for very extensive exhibiting spaces.
- To overcome said drawback, the object of the present invention is a toy building block having the characteristics set out in the claims.
- The characteristics and the advantages of the present invention shall become readily apparent in the detailed description that follows, provided purely by way of non limiting example, with reference to the accompanying drawings, in which:
-
FIG. 1 is a plan view of an element for forming a building block according to the present invention, -
FIG. 2 is a section according to the line II-II ofFIG. 1 , -
FIG. 3 is plan view of the part indicated by the arrow III inFIG. 1 , -
FIG. 4 is a section according to the line IV-IV ofFIG. 3 , -
FIG. 5 is a view according to the arrow V ofFIG. 4 , -
FIG. 6 is a section corresponding toFIG. 4 , showing the bending region in closed configuration, -
FIG. 7 is a plan view of a first embodiment of a building block according to the invention, -
FIG. 8 is an elevation view according to the arrow VII ofFIG. 7 , -
FIG. 9 is a section according to the line IX-IX ofFIG. 7 , -
FIGS. 10, 11 and 12 are views corresponding toFIGS. 7, 8 and 9, showing a dimensional variant of the block according to the invention, -
FIG. 13 is a plan view of a second embodiment of a building block according to the invention, -
FIG. 14 is a section according to the line XIV-XIV ofFIG. 13 , and -
FIG. 15 is a section according to the line XIV-XIV ofFIGS. 13 and 14 coupled to a block of the same kind. - With reference to
FIGS. 1 and 2 ,FIG. 1 is a plan view of an element for forming a building block according to the present invention. Thepliable element 10 is constituted by mouldable plastic material and it is obtained by injection or compression moulding. Thepliable element 10 has a perimeter whose shape corresponds to the planar development of the building block. Theelement 10 comprises a plurality ofportions 12, each of which is connected to the adjacent portions by means of ahinge 14. Eachportion 12 is to form a face of the building block. Thehinges 14 are formed by substantially V shaped grooves which extend along the junction line between two adjacent sides of theportions 12. - In the example illustrated in the figures, the
pliable element 10 forms a hollow parallelepiped structure and it is thus provided with sixportions 12 intended to form the six faces of the parallelepiped structure. The present invention however, could be used to obtain building blocks with different shapes from the parallelepiped shape, e.g. pyramidal, pentagonal, etc. The number, the shape and the arrangement of theportions 12 of thepliable element 10 varies according to the shape of the building block. Eachportion 12 will in any case have the shape of one of the faces of the block. - The
element 10 is provided planar, substantially in the form of a plate, with theportions 12 substantially coplanar to each other. After purchasing the toy package, the user assembles the building blocks by folding theportions 12 along therespective hinges 14 and mutually fastening theportions 12 in the manner described below. - Each
pliable portion 12 is provided with fastening means that allow to fasten at least one side of aportion 12 to at least one corresponding side of aportion 12 which forms an adjacent face in the three-dimensional structure. - With reference to
FIGS. 3 through 6 , according to a preferred embodiment of the present invention the fastening means comprise a plurality ofteeth 16 able to be inserted in snap-in fashion intocomplementary grooves 18. The fastening means are provided on at least one side of aportion 12 and they comprise a rectilinear back formed byalternating teeth 16 andgrooves 18. - Each
tooth 16 is preferably provided with a widenedhead 20 with a triangular profile able to be inserted in snap-in fashion into agroove 18 of the complementary fastening means. As shown inFIG. 5 , eachgroove 18 is formed in a substantially fork-shaped element, delimited by twolateral cuts 22 which allow the outwards deformation of the walls delimiting thegroove 18. The array of fastening means 18, 20 preferably extends along an edge of aportion 12. The edges of theportions 12 are preferably provided with inclined bearing surfaces 24 (FIG. 4 ) which bear against complementary bearing portions of aportion 12 which forms an adjacent face in the three-dimensional structure. - As shown in
FIG. 6 , after the rotation of apliable portion 12 about arespective hinge 14, theinclined surfaces 24 of two adjacent sides come in contact with each other and thehead 20 of eachtooth 16 engages in snap-in fashion thecomplementary groove 18 provided on the adjacent side of theother portion 12. -
FIGS. 7, 8 and 9 show abuilding block 26 obtained after the relative fastening of the initially coplanarpliable portions 12 of theelement 10. Thebuilding block 26 comprises a hollow three-dimensional structure that, in the example illustrated inFIGS. 7 through 9 , has a parallelepiped shape with square base. In the variant illustrated inFIGS. 10 through 12 , the hollow three-dimensional structure of thebuilding block 26 has a parallelepiped shape with rectangular base. Purely by way of indication, the dimensions of the building blocks illustrated inFIGS. 8 through 9 and 10 through 12 may be multiples of the length of the smaller side of the structure. For example, hypothesising that theblocks 26 have a height of 40 mm, the dimensions of the block illustrated inFIGS. 7 through 9 could be 80×80×40 mm, whilst the dimensions of the block illustrated inFIGS. 10 through 12 could be 80×160×40 mm. Naturally, these measurements are provided purely by way of example and they in no way exclude the application of the invention to blocks with different dimensions. - Each
building block 26 is provided with engagement means able to co-operate with corresponding engagement means of another block to connect the blocks to each other in stable, disengageable fashion. - In the variant illustrated in
FIGS. 8 through 12 , the engagement means comprisepermanent magnets 28 positioned on at least one face of the block. In the illustrated example, thepermanent magnets 28 are positioned on the two mainopposite faces 30 of the block. In the version illustrated inFIGS. 7 through 9 , a singlepermanent magnet 28 is provided on eachmain face 30 of theblock 26 whilst in the version illustrated inFIGS. 10 through 12 twopermanent magnets 28 are provided on eachmain face 30. Thepermanent magnets 28 can have substantially disk shape and they are preferably housed in lowered seats, so that the outer surface of themagnets 28 is substantially flush with the outer surface of the respective face. Preferably, in addition to the engagement means constituted by thepermanent magnets 28, positioning means can be provided, constituted by projectingportions 32 on one of themain faces 30 and recessedseats 34 whose shape corresponds to theprojections 32 formed on the othermain face 30. Theprojections 32 and therecessed seats 34 may have hemispherical shape. - In the embodiment illustrated in
FIGS. 13 through 16 , the engagement means achieve a mechanical type of engagement. In this case, on one of the main faces 30 are providedprojections 36 with cylindrical shape and on the othermain face 30 are provided recessedseats 38 whose shape and dimensions are complementary to those of the projectingportions 36. The projectingportions 36 have anannular rib 40 whilst the recessedseats 38 are provided withannular grooves 42 with complementary shape relative to theribs 40. As shown inFIG. 15 , when theprojections 36 of afirst block 26 are inserted into the recessedseats 38 of asecond block 26, theribs 40 of the first block engage in snap-in fashion thegrooves 42 of the second block. - Naturally, without altering the principle of the invention, the construction details and the embodiments may be widely varied from what is described and illustrated herein, without thereby departing from the scope of the invention, as defined by the appended claims.
