IMPROVEMENT IN INTERLOCKING TOY BRICKS

Description

[0001] An example of known building blocks is the one with patent specification number CA2337238 in which building block has upper and lower connecting male and female dovetails, in its sidewalls, to be connected to each other.

[0002] Another, of such known, building or interlocking blocks are those in European patent specification number EP0766585 in which the building elements can be clicked and assembled with identical elements to form patterns. According to the description made, it is not possible as described on the abovementioned patent to get such bricks to click a fourth brick with three already assembled to form a square. The only way to get a fourth brick with three already assembled to form a square is by sliding the fourth element from above.

• While such building toy can build a variety of patterns, its versatility or ability to build up with other shaped bricks is somewhat limited.

[0003] However, it is an object of the present invention to provide with interlocking bricks which are even more versatile.

[0004] Accordingly, this invention provides a plurality of interlocking brick elements provided in a variety of different shapes and different colors to be interlocked between each other to form precise and coherent patterns of extreme details. Each brick element include an upper part, a lower part and an annular recess which is positioned between the upper and the lower parts and which Surrounds the middle part of the longitudinal height of the brick element. The upper part of the brick is formed of a regular circle, regular polygonal or partly spherical shape; the lower part of the brick element is formed of circular or polygonal shapes and has on its longitudinal height at least one longitudinal tongue and at least one longitudinal groove, and these tongues and grooves are shaped and configured so 30 that they can frictionally slide between each other and to be releasably interlocked. The clearance provided by the annular recess within the brick elements enables the tongues of the bricks to engage through and slide into corresponding grooves of other already assembled bricks to form a variety of coherent patterns with tongues and grooves hidden by the upper part of the brick elements.

[0005] Furthermore, at least some of the brick elements having polygonal shapes are provided with one or more concave and/or one or more convex complementary side walls.

[0006] Preferably the toy bricks are made of rigid or semi rigid suitable plastic materials in a variety of different sizes and different colors. The advantages offered by this invention are mainly: a) All interlocking bricks require no other means to be assembled such as glue, magnets or base plates.

b) The toy bricks are provided in different sizes so that they can suit all different ages.

c) The toy bricks have high educational and entertainment value and can be used to create pixel artistic frames where the size and design of the pixel frames is only limited by the desire and imagination of the users and where the patterns created can stood on a surface or hung on a wall as decorative and artistic work of art. Other advantageous, objects and novel features of the present invention will become more apparent with the following description and the added drawings in which:

FIG.16 shows a combination of few bricks of different shapes assembled and interlocked between each other.

FIG.17.A-17.C illustrate some different tongues and corresponding groove pairs that can be used by the brick elements of the present invention.

FIG.18 shows an artistic pixel frame, at a very reduced scale, created by using the brick elements of the present invention.

[0007] Referring to the drawings, FIG.1 shows a perspective top view at an enlarged scale of the interlocking brick element 10 according to the present invention in which the brick10 is formed with an upper part 11, lower part 12 and an annular recess 13 which is positioned between the upper part 11 and lower part 12 and which surrounds the middle part of the longitudinal height of the brick element 10.

[0008] The diameters of the upper part 11 and lower part 12 are equal in size. The top of the upper part 11 shows a regular circular shape. The lower part 12 has on its periphery two adjacent tongues 14 and two corresponding adjacent grooves 15.

[0009] The tongues 14 and the grooves 15 extend along the longitudinal height of lower part 12, and these tongues 14 and grooves 15 are shaped and configured so that they can frictionally slide from above into each other as shown in FIG.4 and be releasably interlocked. The tongues 14 as well as the grooves 15 can be positioned to be adjacent or to be opposite to each other and can be positioned to be in different angular positions between each other. The recess 13 has a height H slightly bigger than the height D of the tongues 14 and has a depth J slightly bigger than the width K of the tongues 14, as shown in FIG.4, to allow enough space for the tongues 14 to engage in the recess 13 and frictionally slide into the corresponding groove 15. With the brick elements of the present invention, the tongues and grooves are always hidden by the upper part 11 of the brick elements and the final created pattern is always precise, coherent and well detailed. The big advantage of having the annular recess 13 formed in the brick elements is to allow not only to slide, a forth brick with three already assembled to form a square as shown in FIG.15 but it allows as well to add a brick element to fill a gap 64 between two other brick elements as shown in the pattern of FIG.16.

[0010] FIG.2 shows a perspective top view at an enlarged scale of another brick element 20 according to the present invention in which the upper part 21 can be formed with a polygonal shape which can be hexagonal, triangular or square. In the case of the brick element 20 of FIG.2, the upper part 21 shows a regular square and the lower part 12 is similar to the lower part 12 of the brick element 10 of FIG.1. The width W of the of the side of the square is equal to the diameter Z of the lower part 12 to allow a construction of coherent patterns without openings between the brick elements.

[0011] The shapes of the upper parts and lower parts of the bricks can be both circular or both polygonal or can be a combination of both polygonal and circular shapes. The top of the brick elements may be formed as well of partly spherical shape.

[0012] FIG.3 shows a perspective bottom view of the brick element of FIG.1 in which we can see that the bottom of the brick is hollow. The bottom of the bricks may also be provided close as very small brick elements are also designed for the present invention to create pixel art frames.

The brick elements 70 can be assembled between each other through the tongues 14 and corresponding grooves15 as well as through the corresponding cylindrical protruding portions 16 and 71 to provide with a two or three dimensional patterns or designs.

[0017] FIG.8 shows a top perspective view, at an enlarged scale, of a peg element 80 according to the present invention in which the peg 80 is formed with an upper part 11 similar to the one of brick element 10 of FIG.1. The lower part of the peg is formed with a stem 81 which has a recessed bottom 82 which is made to frictionally fit in the recess 91 of the base elements 90 and 100 of respectively FIGS.9and10 to provide with brick elements similar to the brick 10 of FIG.1.

[0018] FIG.9 shows a perspective top view, at an enlarged scale, of a base support element 90 which could be made of circular or polygonal shape. The base support 90 is provided with at least one tongue 14 and one corresponding groove 15 that extend along the longitudinal height of base element 90. The centre of the base element 90 is formed with a recess 91 protruding through which is used to frictionally receive and retain the peg 80 to create a brick element similar to the one of FIG.1.

[0019] In FIG.9, the tongues 14 as well as the grooves 15 of the base element are spaced apart by 90 deg angles which allows the creation of patterns having rows similar to the ones shown in FIG.13 where the rows are mounted one above the other without displacement between the rows.

[0020] FIG.10 shows another base support element 100 similar to the one of FIG.9 in which the tongues 14 as well as the grooves 15 are spaced by 135 degrees angle which allows the creation of patterns having displaced rows similar to the ones shown in FIG.14

[0021] FIG.11 shows a top front perspective view of another brick element 200, with a larger size than the brick element 20 of FIG.2. Here the brick element 200 is shown with a shape of a planar square tile, which is designed for younger children of an early age. The brick element 200 can be provided in different shapes to include a circle, an oval shape, a leaf having two concave arcs, a crescent and a polygon. At least some of the polygonal brick elements of the present invention are provided with one or more concave and/or one or more convex sides, as shown in FIG.12 and in the tiles 88 and 89 of FIG.16, and where the concave and convex sides are complementary to each other.

[0022] FIG.12 shows a perspective bottom view of another brick element 300 having planar triangular shape which has two concave sides and one convex side. The brick 300 shows the annular recess 13, tongue 14 and corresponding groove 15 similar to the ones of brick element of FIG.1 for the same purpose.

[0023] FIG.12.A shows a top view, at a reduced scale, of a small pattern created by assembling a plurality of bricks 300 of FIG.12.

[0024] The top surface of the brick elements of the present invention can be provided with representations of letters, digits or symbols for educational and teaching purposes or to be used as puzzles.

[0025] The brick elements of the present invention are also formed of very small size so that pixel art frames of different designs and different sizes can be created such as the pixel frame shown in FIG.18, at a very reduced scale.

[0026] FIG.17.A-17.C show some different shapes of tongue 14 and groove 15 pairs that may be used in the brick elements of the present invention. Other shapes of tongues and grooves can also be used in these brick elements.
