Description

CONSTRUCTION TOY SYSTEM

The invention refers in a construction toy system comprising a plurality of blocks which the user joins them in order to create constructions. Because of the basic and innovative geometry of the blocks which comprising at least two parts is achieved the elimination of many disadvantages of the current construction toys and the reduction of the production cost. The blocks are mainly joined without the use of additional means

Construction toy systems of this category are mainly characterized that they comprising by a variety of blocks which the user connects them when a protrusion of a block enters in a recess of another block.

In this category of construction toys there is a huge number of known construction toy systems with many different technical characteristics and big variety in their geometry.

Despite the huge number of the existing construction toy systems there are plenty of common disadvantages in those. Some of them are:

1) The geometry of the blocks is often relatively sharp and as result the blocks are dangerous for use by children, which these construction systems are mainly addressed.

2) Constructions in some systems separate easily as the blocks are not joined tight enough to each other.

3) Other systems have the opposite disadvantage, their blocks are joined very tight and it is difficult for the user to disconnect them. The same can happen due to the fact that when the blocks are joined they create a single surface and because of that the user can not easily separate the blocks.

4) In many systems it is difficult for the user to change the direction of the construction he creates because the blocks are mainly built the one in top of the other.

5) The construction of many of these construction toys is quite simple and clumpy.

6) Also in some systems there is a lack of a variety of different blocks resulting in few construction possibilities.

7) Many construction systems have complicated blocks which have difficult and expensive production.

The toy construction system of the present invention overcomes these disadvantages with the novel basic geometry of its blocks (1) which are characterized by the following particular features.

Each block (1) comprising at least two parts (2). Each part (2) has six basic surfaces (21) which are parallel to each other. Also, each part (2) has at least two transition surfaces (22) each connecting two perpendicular basic surfaces (21) of the same part (2).

Every part (2) is inscribed in a theoretical rectangular parallelepiped (26) having six sides (27), twelve edges (28) and dimensions X, Y, Z of which at least two parallel sides (27) are square. Each basic surface (21) touches a side (27) of the theoretical rectangular parallelepiped (26). The layout of the parts (2) is such that each theoretical rectangular parallelepiped (26) has a common edge (28) with at least one other theoretical rectangular parallelepiped (26) and the angle between them is 90 degrees. The sides (27) of two theoretical rectangular parallelepipeds (26) do not touch each other.

Each part (2) is connected with at least one other part (2) through a connection (3) on the common edge (28) of the theoretical rectangular parallelepipeds (26) in which they are inscribed, to form a unified block (1). Each connection (3) has two connection surfaces (31), each connecting two perpendicular basic surfaces (21), one of each part (2) that the connection (3) connects.

Most of the blocks (1) of the construction toy system have sockets (4), which are formed between at least three parts (2).

The blocks (1) are joined to one another when at least one part (2) of a block (1) enters a socket (4) of another block (1) and is wedged due to the fact that at least one dimension of the part (2) is equal with at least one dimension of the socket (4), since the sockets (4) are formed between the parts (2).

In the construction toy system of this invention, there is also the possibility of indirectly connecting the blocks (1) using supplementary blocks (9).

The user plays with the construction toy by joining the blocks (1) to each other, creating constructions.

The construction system can also be used for the construction of decorative elements, furniture, artistic creations and compositions, usable objects, structures and for any other use where its geometry and function offer advantages.

Join to this invention is called the process by which the user joins a block (1) to another block (1). Connection (3) is the element of the invention which unifies the parts (2) to form a single block (1) of the construction toy.

The construction toy system of the present invention has a number of advantages such as:

1) The possibility of a wide variety of different blocks (1) because of the large number of possible layouts of the parts (2).

2) Many ways of joining the blocks (1), both between blocks (1) with the same geometry and between blocks (1) with different geometry.

3) Due to the geometry of the blocks (1), the user that joins the blocks (1) has the ability to change frequently and easily the direction of the composition of the blocks (1) in the space, something very important in a construction toy.

4) The blocks (1) can be manufactured easily and industrially using relatively simple molds, meaning that the product will have a high quality and a low price.

5) Both operatively and aesthetically, the blocks (1) have a distinct and original character, resulting in that the creations with the construction system of the present invention being unique. 6) It can be used as learning toy, when children play with blocks (1) it improves their sense of space and of the volume of objects and cultivates their synthetic abilities.

7) Essentially, the present invention presents a hybrid construction toy system in which the blocks (1) have multiple ways of join each other, both direct and indirect, giving the user a wide range of possibilities.

8) It is safe for the user as the parts (2) of the blocks (1) have no sharp edges and corners but a user-friendly geometry due to the transition surfaces (22).

9) The blocks (1) are firmly joined to each other because when a part (2) of a block (1) enters in the socket (4) of another block (1), the entire basic surfaces (21) of both blocks (1) are touching. 10) The blocks (1) are easily separated by the user as when two blocks (1) are joined, slots are created between the parts (2) due to the transition surfaces (22) and the user can use his fingertips and nails to separate the blocks (1).

In Figures 73 to 83 in the blocks (1) the transition surfaces (22) of the parts (2) are flat transition surfaces (222) (chamfers). Similarly the connection surfaces (31) of the connections (3) are flat connection surfaces (312). According to the selected indicative embodiment of the invention, the construction toy system comprising a number of basic blocks (1) of different types characterized by the particular geometry of the present invention as well as supplementary blocks (9) of various types.

Each block (1) comprising at least two parts (2). Each part (2) has six basic surfaces (21) which are parallel per two. Each of the part (2) has at least two transition surfaces (22) each connecting two perpendicular basic surfaces (21) of the same part (2).

Each part (2) is inscribed in a theoretical rectangular parallelepiped (26) having six sides (27), twelve edges (28) and dimensions X, Y, Z of which at least two parallel sides (27) are squares. Each basic surface (21) abuts a side (27) of the theoretical rectangular parallelepiped (26).

In a block (1), the layout of the parts (2) is such that each theoretical rectangular parallelepiped (26) has a common edge (28) with at least one other theoretical rectangular parallelepiped (26) and the angle between them is 90 degrees. The sides (27) of two theoretical rectangular parallelepipeds (26) do not touch each other.

Each part (2) is connected to at least one other part (2) through a connection (3) on the common edge (28) of the theoretical rectangular parallelepipeds (26) in which they are inscribed, forming a unified block (1). Each connection (3) has two connection surfaces (31), each connecting two perpendicular basic surfaces (21), one of each part (2) that the connection (3) connects.

Most of the blocks (1) of the system have sockets (4) that formed between at least three parts (2).

The blocks (1) are joined to each other when at least one part (2) of a block (1) enters one socket (4) of another block (1) and snaps because at least one dimension of the part (1) is equal with one dimension of the socket (4), because the sockets (4) are formed between the parts (2).

The parts (2) have a multiple role in this construction toy system as they constitute the main body of each block (1), their layout forms the sockets (4) and at the same time they are the "male" part (2) of the block (1) which is wedged in the "female" socket (4) of another block (1).

In one block (1) a part (2) has at least two transition surfaces (22) to be able to join to a socket (4) of another block (1) because this socket (4) has at least two connection surfaces (31).

In addition to the basic surfaces (21) of the transition surfaces (22) and the connection surfaces (31), each block (1) has the necessary closing surfaces so that its entire surface is close and uniform. Closing surfaces are actually the natural continuity of the transition surfaces (22) and the connection surfaces (31).

The transition surfaces (22) of the parts (2) are convex transition surfaces (221), are curved surfaces (fillets). Respectively and the connection surfaces (31) of the connections (3) are concave transition surfaces (311).

Transition surfaces (22) are slightly smaller than the connection surfaces (31) so that when a part (2) of a block (1) enters a socket (4) of another block (1) to touch only the basic surfaces (21) of the parts (2) in order to achieve easy and controlled use of the blocks (1). As shown in figures 1 through 60, this embodiment has a wide variety of different blocks (1) which results in many possibilities in the composition of constructions.

The layout of the parts (2) of some blocks (1) is in a theoretical plane. For example, in figures 1, 5 to 8 and 10 to 26.

The layout of the parts (2) of some blocks (1) is in multiple theoretical parallel planes. For example, in figures 27 to 37.

The parts (2) may have recesses (5) in the center of their basic surfaces (21). As an example, the blocks (1) in figures 1, 7, 30, 31 and 46 to 54 can be used.

The parts (2) may have holes (6) in the center of their basic surfaces (21). As an example, the blocks (1) in figures 6, 8, 22 and 30 can be used.

The recesses (5) and the holes (6) in the parts (2) of the blocks (1) also help the uniform distribution of the mass shrinkage of the block (1) when it is produced by molding.

The parts (2) may have "male" protrusions (7) in the center of their basic surfaces (21). As an example, blocks (1) in figures 7, 8, 23 and 46 to 54 may be used.

A number of blocks (1) have parts (2) wherein the theoretical rectangular parallelepipeds (26) of dimensions X, Y, Z wherein they are inscribed are cubes, X = Y = Z. As shown in figures 1 to 8, 10 to 23 and 27 to 36.

As shown in the figures from 46 to 54, a number of blocks (1) have parts (2) where the theoretical rectangular parallelepipeds (26) dimensions X, Y, Z in which they are inscribed are half cubes, X = Y = 2Z. The user can use these blocks (1) to directly create constructions. In addition, as shown in figures 58, 59 and 60, he can connect them together to create compositions where they look like basic blocks (1) which can be further re-joined to create constructions. This offers the advantage that with a smaller number of different basic blocks (1) and supplementary blocks (9) the user can create on his own large number of compositions where they look like basic blocks (1) and can used that way.

This embodiment also includes a plurality of supplementary blocks (9). As an example, the supplementary blocks (9) in figures 9, 39 to 42 and 55 to 57 may be used.

There are at least two kinds of supplementary blocks (9).

The supplementary blocks (91) which enter the sockets (4) of the basic blocks (1). Some examples are shown in figures 39 and 40.

The thin supplementary blocks (92) which enter the recesses (5) and the holes (6) of the blocks (1). Some examples are shown in Figures 41 and 42.

The blocks (1) can be joined by the following ways:

1) The blocks (1) can be joined directly to each other without additional means when at least one part (2) of a block (1) enters at least one socket (4) of another block (1).

2) The blocks (1) can be joined directly to each other without additional means when at least one protrusion (7) of a block (1) enters at least one recess (5) or a hole (6) of another block (1).

3) The blocks (1) can be joined indirectly with the use of supplementary blocks (91), when a supplementary block (91) enters the sockets (4) of the blocks (1).

4) The blocks (1) can be joined indirectly with the use of supplementary blocks (91), when a supplementary block (91) enters the recesses (5) and/or the holes (6) of the blocks (1).

Another embodiment the invention as shown in the figures 72 to 82 is the following. The basic geometry of the system such as parts (2), connections (3) and the sockets (4) as well as additional elements such as recesses (5), holes (6) and the protrusions (7) remain the same. But differs on that the transition surfaces (22) of the parts (2) are flat transition surfaces (222) (chamfers). Similarly the connection surfaces (31) are flat connection surfaces (312)(chamfers). By the same principle, the transition surfaces (22) of the parts (2) and the connection surfaces

(31) of the connections (3) may have any profile shape such as a linear, curved, zig-zag, and any combination of them.

In its most simplified embodiment, the construction toy system can function with a number of blocks (1) of exactly the same geometry. Meaning exactly the same block (1) many times. As a example can be used the block (1) of the figure 1.

In an alternative embodiment of the construction game, the blocks (1) have an inner structure from any hard and durable material to be more resistant to use. In one embodiment the inner structure has similar geometry with the block (1) and is essentially a parallel offset of all the surfaces of the block (1) to the inside.

As shown by the description, the blocks (1) of the construction system are not limited to any construction method, material, size and color.

The blocks (1) and the supplementary blocks (9) of the construction toy can be made in any known production method, for example: using molds, through three-dimensional printer, via CNC, etc.

The blocks (1) and the supplementary blocks (9) may be made of any known material. Is suggested plastic material suitable for toys, such as acrylonitrile-butadiene-styrene (ABS), polyethylene (PE), polypropylene (PP), etc. In an alternative embodiment they may be made from wood.

The blocks (1) and the supplementary blocks (9) can be made in any size. Size selection depends on the use they are intended and the target age of the users.

The blocks (1) and the supplementary blocks (9) can be made in any color.
