Toy building block
Toy building block comprising a hollow three-dimensional structure with a plurality of faces and provided on at least one of said faces with engagement means able to co-operate with complementary engagement means of another block. The three-dimensional structure is formed by a pliable element with a perimeter whose shape corresponds to the planar development of the block. The pliable element is provided with hinges between adjacent portions forming the faces of the three-dimensional structure. Snap-in fastening means are provided for fastening each of said faces to an adjacent face of the three-dimensional structure.
This application claims benefit of Italian Patent Application serial number TO2004A000578, filed Aug. 31, 2004, which is herein incorporated by reference.
BACKGROUND OF THE INVENTION1. 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.
SUMMARY OF THE INVENTIONThe 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.
BRIEF DESCRIPTION OF THE DRAWINGSThe 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:
With reference to
In the example illustrated in the figures, the pliable element 10 forms a hollow parallelepiped structure and it is thus provided with six portions 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 the portions 12 of the pliable element 10 varies according to the shape of the building block. Each portion 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 the portions 12 substantially coplanar to each other. After purchasing the toy package, the user assembles the building blocks by folding the portions 12 along the respective hinges 14 and mutually fastening the portions 12 in the manner described below.
Each pliable portion 12 is provided with fastening means that allow to fasten at least one side of a portion 12 to at least one corresponding side of a portion 12 which forms an adjacent face in the three-dimensional structure.
With reference to
Each tooth 16 is preferably provided with a widened head 20 with a triangular profile able to be inserted in snap-in fashion into a groove 18 of the complementary fastening means. As shown in
As shown in
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
In the embodiment illustrated in
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.
Claims
1. A toy building block comprising a hollow three-dimensional structure with a plurality of faces and provided on at least one of said faces with engagement means able to co-operate with complementary engagement means of another block, characterised in that the three-dimensional structure is formed by a pliable element with a perimeter whose shape corresponds to the planar development of the block, the pliable element being provided with hinges between adjacent portions forming the faces of the three-dimensional structure, snap-in fastening means being provided for fastening each of said faces to an adjacent face of the three-dimensional structure.
2. Building block as claimed in claim 1, wherein said snap-in fastening means extend along the sides of respective faces.
3. Building block as claimed in claim 2, wherein said fastening means comprise alternating teeth and grooves.
4. Building block as claimed in claim 1, wherein said fastening means for connection to another block comprise permanent magnets.
5. Building block as claimed in claim 1, wherein said engagement means for connection to another block comprise projecting portions and recessed seats whose shape is complementary to said projecting portions and snap-in engagement portions provided on said projecting portions and recessed seats.
