Description
- This invention relates to a modular unit for forming constructions for toy use. More specifically, the term modular unit refers to systems for construction of toys for children having modular blocks which can be associated with each other to form different types of constructions.
- In effect, it is known that these modular systems for forming constructions comprise blocks of various sizes and colours.
- Each block, which is usually obtained by moulding in shapes, comprises at least one shaped base body, usually cubic or parallelepiped in shape having a first face equipped with one or more radial protrusions arranged according to a certain predetermined order and with variable geometrical shapes such as, for example, cylindrical or polyhedral. The body has a second face, normally opposite the first, wherein there are seats which can be coupled with the protrusions of another body with a cubic or parallelepiped shape.
- These blocks can therefore be assembled stably to each other to form various types of constructions for toy use for children, such as houses, castles, etc.

US 4,254,574 discloses a building block for toys. The building block is formed of sheet material such as corrugated cardboard. The sheet material is a block element in a hollow form comprising end walls, one which has a polygonal aperture and the other of which has a coacting polygonal raised rim that is formed by folded tabs cut from the end and coacting tabs folded from an underlying end wall. The raised rim coacts with the apertures of other block elements to provide element-to-element interconnecting means and the raised rim also functions to secure the hollow-form block structure of the assembled, folded block element. - At present, these modules or pieces are obtained, as mentioned above, by plastic moulding in suitable dies.
- However, this technology results in several drawbacks.
- The first of these drawbacks is due to the large size of the blocks during packaging. Basically, the greater the number of parts necessary for assembling a construction, the larger is the package which must contain the blocks.
- A second drawback, linked to the first, is the overall cost of a complete kit for a certain construction due both to the number of blocks and the complexity of the package which must contain them.
- A third drawback is due also to the fact that the modules made of plastic, if dispersed, are harmful to the environment.
- The aim of this invention is to provide a modular unit for forming constructions for toy use which overcomes the above-mentioned drawbacks of the prior art.
- More specifically, the aim of this invention is to provide a modular unit forming constructions for toy use which can use a reduced space during packaging.
- A further aim of this invention is to provide a modular unit for forming constructions for toy use which is able to combine logical assembly sequences with the toy use for which it is designed.
- These aims are fully achieved by a modular unit for forming constructions for toy use according to this invention as characterised in the appended claims.
- More specifically, the modular unit for forming constructions for toy use according to the invention comprises a first body with a prismatic shape, formed by a first blank made of foldable material having a central portion with four sides, which defines, in use, the upper side of the first body, and equipped with a pair of through slits for each side, in such a way as to delimit a central zone of it.
- Again according to the invention, the first blank has a wing protruding from each side of the central portion and comprising, each, three different consecutive parts defined by transversal pre-folds to form, in use, corresponding sides of the first body, and a base flat lower edge of the first body.
- Again according to the invention, lower edge delimits a hollow central compartment of the first body having a first space.
- Also according to the invention, the modular unit comprises a second body with a prismatic shape, smaller than the first body, formed by a second blank made of foldable material having a central portion with four sides, which defines, in use, the upper side of the second body.
- Also according to the invention, the second blank has a wing for each side of the central portion, which defines, in use, a side of the second body.
- Again according to the invention, each wing of the second body has a protrusion protruding from the free side of the wing and designed for coupling stably by slotting into a corresponding pair of slits present on the upper side of the first body to define the complete the modular unit formed by the two superposed bodies. The second body has, in use, a shape and a size such that it is matchingly shaped to be housed in a central compartment of a first body forming another similar modular unit.
- The modular unit composed in this way allows an extremely practical construction component to be obtained, starting from flat blanks made of paper material, and which is able to generate different types of toy constructions of various kinds, from the easiest to the most complex.
- The use of flat blanks, at least at the start, allows a twofold advantage provided by the reduced size of the components, and hence a package which is extremely convenient and economical, as well as making the assembly of the component a game in itself.
