CONSTRUCTION TOY WITH INTERLOCKING ELEMENTS

Abstract

The present invention relates to a construction toy with interlocking tile-shaped pieces. Each tile-shaped piece has at least two interlocking elements on each side. One element is a male mating portion and the other is a female mating portion, so that each side of any tile-shaped piece is hermaphroditic in relation to any side of another piece, and the pieces can be locked to each other to form a two-dimensional and three-dimensional construction. The tile-shaped pieces must be oriented in the same plane for the interlocking elements to lock. Each interlocking element has a sphere-shaped configuration on a cylindrical stem that is connected to the side of the tile-shaped piece. The male mating portion has a convex configuration as a function of the interlocking element's spherical shape, and the female mating portion is a concavity in the interlocking element that mates with the male portion to lock interlocking elements together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0029] The present invention refers to a child-friendly safe interlocking building block or tile system for constructing two- and three-dimensional structures. The interlocking feature of the present invention comprises cooperation between a novel interlocking element system, wherein male and female portions lock together in a lattice format.

[0030] Due to the fact that each side's interlocking means are hermaphroditic, the possibilities of intercooperation between tiles are more numerous than if a tile's side were only male or only female. Notwithstanding the geometric shape of adjacent tiles, their sides will click or join together. The added feature of the interlocking means being similar to hinge knuckles allow rotation of one tile with relation to another, permitting a wide range of structures only limited by the imagination.

[0031] Referring now to drawings, FIG. 1 shows the preferred embodiment of the present invention, namely construction tile 2. Tile 2 is substantially square and flat. Tile 2 comprises square body 4 with a top portion 6, bottom portion 8, and tile periphery 10. Interlocking elements 12 protrude from periphery 10, and each element 12 comprises cylindrical stem 14 that connects periphery 10 to interlocking means 15. Stem 14 is adapted to flex during locking and unlocking of said interlocking elements 12.

[0032] Interlocking means 15 comprise either an interlocking means with a male mating portion 16 or a female mating portion 17. Said male interlocking means 16 comprises a sphere incorporating male mating portion 20, and said female interlocking means 17 comprises a sphere, on one side with a concavity or female locking portion 18, and on the other side a neutral mating portion 22, being substantially flat. It must be emphasized that neutral mating portion 22 is not essential to the functionality of the present invention. If there were no neutral mating portion 22, the invention would still work as designed, but it would be aesthetically less pleasing since there would be two interlocking means 15 on one side and two interlocking means 15 on the other side. With neutral mating portion 22, the four interlocking means 15 are aligned straight and evenly.

[0033] Tile body 4 also has a receiving cavity 28 substantially in its center, comprising a round hole adapted to receive and lock elongated connector 26 or short connector 30, as seen on FIG. 4. Said locking of elongated connector 26 or short connector 30 is accomplished by receiving cavity 28's female mating portion 29, adapted to receive a male mating portion 27 of elongated connector 26 or short connector 30, seen on FIG. 4.

[0034] FIG. 2 shows another embodiment of the present invention, wherein interlocking means 15 are not spherical but flattened, resembling clothing buttons. Interlocking portions 16 and 17 are configured identical to the embodiment in FIG. 1, with female mating portions 18 and male mating portions 20 intercooperating as described in FIG. 1.

[0035] FIG. 3 demonstrates various embodiments of body 4 shapes that can be operably used for the present invention. Due to the fact that each side's interlocking means 15 is hermaphroditic, any shape can be joined to any other shape.

[0036] FIG. 4 shows elongated connectors 26 of various lengths, and short connector 30. Elongated connectors 26 and short connector 30 comprise a cylindrical body with male mating portions 27 on the ends. Short connector 30 is used to affix two tiles 2 in close proximity so that the two tiles 2 are stacked, to simulate a neck between a body and a head (as seen on FIGS. 15 and 16). The head will be able to rotate about the body. Short connector 30 can also serve as a cosmetic feature such as an eye of an animal, as seen on FIGS. 15 and 16.

[0037] Short connector 30 is also necessary if one tile 2 has all interlocking means 15 populated by other tiles 2, and the user needs a fresh tile 2 with all interlocking means 15 available for additional tiles 2. For example, if the user is making a model of a bird (see FIGS. 15 and 16), short connector 30 would connect the tile 2 that makes part of the bird's body to the tile 2 that makes part of the bird's head. This short connector 30 would allow the bird's head to rotate, similar to a real bird's range of motion.

[0038] FIG. 5 shows a sample three-dimensional structure 34 comprising four tiles 2, wherein interlocking elements 12 around tile periphery 10 are interlocked with adjacent interlocking elements 12 between tiles 2. Male mating portions 20 cooperate with female mating portions 18 to provide a secure lock. Force vectors 40 retain interlocking elements 12 together. In the preferred embodiment, there are a minimum of two interlocking elements 12 on each tile periphery 10, said elements 12 are spaced so that there is a gap between them wide enough to accept an interlocking element 12 from another tile 2. In the resulting joint shown on FIG. 5, there are four elements 12, two being on the inside and two being on the outside of said joint. There are three points of contact 13 between the four elements 12. For the invention to function properly, there must be no gap or space between the middle point of contact 13, between the two inside elements 12. If there is any gap or space between points of contact 13, the invention will not work. This is particularly true if there is a gap between point of contact 13 between the two inside elements 12.

[0039] FIG. 6 shows elongated connector 26 inserted into elongated connector receiving cavity 28 in tile body's 4. It should be pointed out that cavity 28 can simultaneously accommodate two connectors 26, one connector 26 on top 6 and one connector 26 on the bottom 8 of tile body 4.

[0040] FIG. 7 shows a sample two-dimensional structure 32, with force vectors 40 exerting force on interlocking means 12, holding tiles 2 together.

[0041] FIG. 8 shows a second variant of the preferred embodiment, wherein male and female interlocking means 16 and 17 are swapped places. It should be noted that this second variant will work as well as the first variant.

[0042] FIG. 9 shows another embodiment of the present invention, being a hinge-type tile 36. Tile 36 comprises interlocking elements 12 without stems 14, resembling hinge knuckles. As seen on FIG. 10, tile 36 also has female and male mating portions 18 and 20 on interlocking means with male mating portions 16 and female mating portions 17. As in the first embodiment, interlocking element with male mating portion 16 has a neutral mating portion 22. Cavity 28 receives elongated connector 26 or short connector 30 by means of female mating means 29 comprising protruding half-spheres inside cavity 28's circumference that lock elongated connector 26's or short connector 30's male mating means 27.

[0043] FIG. 11 demonstrates a variant in female and male mating portions 18 and 20, being of a square-walled configuration. This configuration allows the tiles to be positively locked at 90° and 180° rather than a fluid, axial connection 24 as seen on FIG. 9. FIG. 12 shows another variant of female and male mating portions 18 and 20 with octagonal walls, and FIG. 13 shows polygonal walls. It should be noted that the present embodiment of the positive locking variant is not restricted to the demonstrated variants, and is functional with any number of walls of the female and male mating portions 18 and 20 for a positive-locking intercooperation. It is also important to note that said positive locking variant can be incorporated on the first embodiment that is shown on FIGS. 1-8.

[0044] FIG. 14 shows an elongated connector expander 38 for customizing the length of elongated connectors 26 or short connectors 30, comprising a ring with a female connector 29 on each side for joining two elongated connectors 26 or short connectors 30 end to end. For example, if a user needs to create an elongated connector 26 of a specific length that is not provided, she can use expanders 38 and a plurality of elongated connectors 26 to create the desired length.

[0045] FIGS. 15 and 16 demonstrate a construction 42 of a bird out of tiles 2, elongated connectors 26 and short connectors 30. There are approximately sixty pieces in construction 42. Elongated connector 30 serves as both a neck connecting construction 42's head to body, as well as the eyes. Construction 42 can be animated to an identical degree as a real bird: the wings can pivot and be modeled as the child sees fit, the head can turn, the beak can open and close, and the legs can rotate.

[0046] As seen on FIG. 16, short connectors 30 permit adjacent placement of tiles 2 to expand a construction indefinitely. The body is connected to a neck, which is connected to a head. Said neck comprises one square tile 2 and four triangular tiles 2. All interlocking elements 12 cooperate to join together due to the hermaphroditic nature of the interlocking means 15.

[0047] It should be noted that in the present embodiments, the invention is inoperable unless there are a minimum of two interlocking elements 12 on each periphery 10 of tile 2, and tiles 2 will only interlock as long as tops 6 of each tile are oriented in the same plane. In the preferred embodiment, tiles 2 will not interlock if top 6 and bottom 8 are oriented in the same plane. In any resulting joint of four interlocking elements 12, there will always be two outside and two inside interlocking elements 12.

[0048] Regarding tile 36 of FIG. 10, since there is no stem 14 to flex during connection, it should be noted that the size of the male mating portion 20 is directly proportional to the flexibility of the material of manufacture for tile 36. For example, if tile 36 is made of a very stiff plastic, male mating portion 20 is relatively small to permit interlocking elements 12 to lock. However, if tile 36 is made of very flexible foam, male mating portion 20 should be substantially larger so as not to slip out after mating with female mating portion 20 due to the material's pliant nature. The same principle applies to the embodiment shown on FIGS. 1-8.

[0049] In operation, referring to FIGS. 1-8, user positions tiles 2 so that tops 6 are both in the same plane, and moves interlocking elements 12 towards each other so that female interlocking elements 17 are between male interlocking elements 16. Once interlocking means 15 from two adjoining tiles 2 abut each other, user pushes tiles 2 together so that convex male mating portions 20 on interlocking means 16 slip into concave female mating portions 18 on interlocking means 17. Interlocking elements 12 will flex slightly on stems 14 to permit interlocking means 16 to overcome resilient resistance of interlocking means 17, and seat male mating portion 20 securely into female mating portion 18.

[0050] The resulting lock permits one tile 2 to rotate about an axis 24 with said second tile 2, thus allowing building of two- or three-dimensional structures. User can insert elongated connectors 26 or short connectors 30 into receiving cavities 28 on either the top 6, bottom 8, or both top and bottom 6 and 8 to expand the 2D or 3D construction 32 or 34.

[0051] Referring to FIGS. 9-13, user aligns tiles 36 so that tops 6 are in the same plane, and pushes tiles 36 together so that interlocking elements 12 interconnect, the interlocking means with male mating portion 16 is directly adjacent to the interlocking means with female mating portion 17. User pushes tiles 36 together until male mating portion 20 locks within female mating portion 18. Depending on the variant, the resulting joint will be axial 24 (see FIG. 9) or a positive lock without any rotation about the joint's axis.

[0052] Force vectors 40 keep the resulting joint from loosening due to the fact that one vector 40 is applied inwardly on the joint by one tile 2's outside interlocking element 12, and another vector 40 is being applied in the opposite direction on the joint by the other tile 2's outside interlocking element 12.
