Definitions

  • the invention relates to a kit of construction elements.
  • the construction element toys comprise a plurality of construction elements which can be put together (e.g. construction cubes) or can be engaged with each other (e.g. LEGO) without using any additional binding element. From those construction elements which are attached to each other by surface-fitting, a non-stable assembly can be formed, whereas with construction elements provided with integrated binding elements, only planar surfaces of limited size can be formed. Other construction element tools are also known, wherein openings are formed on the surface of the construction elements for receiving additional close-fitting binding elements (e.g. MySQL, Java). In these construction element toys, however, the construction elements are not defined by planar surfaces, thus by using such construction elements one cannot form continuous, joint planar surfaces.
  • construction elements are not defined by planar surfaces, thus by using such construction elements one cannot form continuous, joint planar surfaces.
  • At least one longitudinal notch is formed in said grooves as securing member, and at least one longitudinal rib is formed on the binding elements as securing member, each rib being adapted to fit into a notch.
  • At least one protrusion is formed in the grooves as securing member, and wherein the binding elements comprise at least one notch for receiving a protrusion.
  • the construction elements are formed as square-based rectangles, wherein the height of the construction elements is a multiple of the edge length of the base.
  • the construction elements and the binding elements are made of plastic.
  • image fields are provided on the faces of the construction elements for presenting logical information.
  • At least one construction element is formed of two or more cubes arranged on each other and held together by a central shaft having studs, and wherein the individual cubes can be rotated independently of each other around said central shaft.
  • the construction elements may have a hollow core and may comprise an opening on at least one of their faces.

It is preferred that the length of the binding elements 20 is shorter than the side length of a particular construction element by the diameter of a binding element. Accordingly, during use further binding elements 20 can be inserted into the transversal grooves at the two ends of the binding elements 20 when they have already been inserted into the respective grooves of the construction elements 10 .
  • the construction elements 10 , their grooves 11 , 12 and the binding elements 20 are dimensioned so that during use the construction elements 10 are substantially in contact with each other along their connecting surfaces. Accordingly, the diameter of the binding elements 20 is substantially equal to the diameter of the grooves extending along the edges and on the lateral surfaces of the construction elements 10 .
  • the lateral grooves 11 of semicircle cross-section formed on their contacting faces together form a hole having the shape of a full circle, thereby being capable of receiving a binding element 20 .
  • a hole having the shape of a full circle is formed when four construction elements 10 are joined along their edges, or when two construction elements 10 joined along their edges are combined with a further construction element 10 attached to former ones by one of its face.
  • the binding elements 20 may have a hollow core as shown, for example, in FIGS. 11 and 12 illustrating the binding elements of FIGS. 2 d and 2 j , wherein a through-hole is formed along their longitudinal axis.
  • the assembled set of construction elements can be made even more stable by inserting a stiffening rod into the aligned binding elements 20 , on the one hand, and due to the absence of material within the through-hole, the binding elements are lighter in weight and due to their capability of light transmission, they are also more spectacular, on the other hand.
  • the outer surface of the binding elements 20 may have different colors so that different sub-groups of the construction elements can be visually distinguished from each other more easily.
  • the majority of the construction elements 10 are formed to have at least one lateral groove 11 on each of four lateral faces thereof perpendicular to their base.
  • the kit of construction elements may also contain construction elements 10 in which not all of the lateral faces perpendicular to the base comprise a lateral groove 11 .
  • a construction element 10 which comprises no lateral groove on its one, two or three lateral faces can be used only as a marginal construction element.
  • the binding elements 20 may be provided with securing members 21 or 22 which can be attached by form-fitting to respective, complementarily shaped securing members 14 , or 15 , 16 of other construction elements 10 .

  • the securing members 21 are provided on the outer surface of the binding element 20 in the form of longitudinal ribs which fit into the complementarily shaped securing members 14 formed in the respective longitudinal grooves of the lateral groves 11 , 12 of the construction element 10 .
  • the binding element 20 four longitudinal ribs are preferably arranged at equal distance from each other as shown, for example, in FIGS. 2 a , 2 c , 2 d and 2 e , and accordingly, an associated notch 14 is formed in the grooves 11 , 12 of the construction elements 10 at every quarter circle position.
  • a binding element 20 is capable of connecting two adjacent construction elements 10 only if at least two of the four ribs formed on its surface fit into the respective notches of the attached construction elements, wherein said two notches belong to two adjacent construction elements 10 which contact each other along their edges or faces.
  • two lateral grooves 11 of semicircle cross-section formed on a lateral face together form a through-hole of full circle cross-section.
  • Each of the four longitudinal ribs of the binding element 20 inserted into the thus obtained through-hole engages with a respective notch of the opposite construction element 10 , as it is shown in FIG. 4 .
  • two construction elements 10 may be connected to each other through a single binding element 20 .
  • two lateral grooves 12 of two construction elements 10 each lateral groove having a quarter circle cross-section, and a semi circle lateral groove 11 of a third construction element 10 together form a through-hole of full circle cross-section.
  • two ribs of the binding element 20 inserted in the through-hole engages with two respective notches of the third construction element 10

  • neither the ribs 21 , nor the grooves 14 extend up to the extremities of the binding elements 20 and the construction elements 10 , but they terminate at a certain distance a from the extremities, as illustrated in FIG. 2 c and FIG. 9 . In this way the overprojection of an inserted binding element 20 beyond the extremities of the associated construction elements 10 can be eliminated, which primarily helps in easily assembling the construction elements.
  • stability of the assembled construction elements 10 may also be enhanced by forming longitudinal notches 22 between the ribs 21 , said notches serving as securing members on the surface of the binding elements 20 . These notches are preferably arranged at an equal distance from the adjacent ribs.
  • longitudinal protrusions 15 , 16 extending towards the binding elements 20 are formed in the lateral grooves 11 , 12 of the construction elements 10 , as shown in FIG. 5 .
  • lateral grooves 12 having a quarter circle cross-section, typically there are two protrusions 15 provided, each serving as a longitudinal flange of the lateral groove.
  • the lateral grooves 11 are preferably formed with three protrusions from which two protrusions 15 are formed as a longitudinal flange of the groove, whereas a third protrusion 16 is arranged in the center of the groove 11 , at an equal distance from the other two end protrusions 15 .
  • the binding elements 20 have only one design within a particular kit, said design being available for use in any combination of the construction elements. Accordingly, the notches 22 are dimensioned so that a single notch 22 is capable of receiving two protrusions 15 at the same time or only one protrusion 16 .
  • the thickness of a protrusion 16 is therefore twice of the thickness of a protrusion 15 .
  • FIG. 6 illustrates another possible solution, wherein the construction elements 10 have no such a central protrusion 16 at all.
  • FIG. 8 there are only protrusions 15 , 16 in the lateral grooves 11 , 12 and there are only notches 22 on the binding elements 20 , while no grooves 14 and ribs 21 are formed at all.
  • other form-fitting connections may also be used, including, for example, bayonet joint, force-fitting, such as an engagement based on friction between the contacting surfaces of the grooves and the binding elements.
  • the insertion of a binding element 20 between the adjacent construction elements is not necessary until a complete through-hole of a full circle cross-section is formed therefrom (although in case of form-fitting connections, it is always possible).
  • the binding elements 20 may be inserted between the construction elements 10 by snapping or, when the ribs 21 and the notches 14 extend up to the extremities of the binding elements and the construction elements 10 , respectively, it may be done also by sliding.
  • the construction elements 10 and the binding elements 20 are made of a material that allows slight flexible deformation thereof, i.e. typically an elastic plastic material.
  • FIG. 11 shows a particular combination of the construction elements 10 and the binding elements 20 of the kit of construction elements, wherein the construction elements can be connected to each other by means of the binding elements 20 not only vertically, but also in a lateral direction.
  • the construction elements have a rectangular form having a square base, wherein the height of the construction elements 10 is equal to the length of the edges of the square base or a multiple of the length of the edges of the square base. Accordingly, in such a kit the binding elements 20 are available with various lengths.
  • FIG. 10 shows a combination of square-based construction elements 10 , wherein the height of the construction elements 10 may be equal to the length of an edge of the base, or even the double or the triple thereof. Accordingly, the binding elements 20 are also available with three different lengths.
  • the lateral grooves 11 which are formed on the lateral faces perpendicular to the base, are spaced apart at a distance which corresponds to the length of an edge of the base.
  • FIG. 12 shows a combination of construction elements in an assembled form wherein various numbers are displayed on the faces of the construction elements. In this embodiment attaching the construction elements to one another should be carried out by taking the numbers into view according to predefined logical rules.
  • the square-based rectangular construction elements 10 are not formed as one piece, rather they comprise multiple individual cubes defined by edges 11 .
  • the individual cubes are attached to each other by means of a central shaft 17 in such a way that the individual cubes can be independently rotated relative to each other around said central shaft 17 .
  • This embodiment allows for the construction elements 10 , for example, to be attached to each other on the basis of various colour-figure combinations or alphanumeric information, according to even more complicated logical rules.

  • the intermediate cubes it may be enough to provide them with a through-hole for receiving the shaft 17 .
  • the rectangular construction elements allow assembling any spatial configurations in which the adjacent construction elements provide continuous, joint planar surfaces. These planar surfaces allow, for example, to display visual information on the faces of the construction elements for logical tasks.
  • the kit of construction elements according to the invention may also be used as a logical toy in itself, i.e. without presenting visual information, as long as it contains a plurality of construction elements of different sizes and/or shapes.
  • Another advantage of the invention is that when it is used as a logical toy, the way of building a specific configuration is not restricted by the three-dimensional design of the construction elements, which is due to the fact that the construction elements are functionally arranged symmetrically with respect to the binding elements.
  • three-dimensional logical toys if a toy includes a plurality of pieces, it is necessary that the construction elements are compatible and conform in terms of their size and connectivity. If a construction element comprises a binding element on one of its faces and a receiving part on its opposite face, then the use of the logical toy is also restricted by its three-dimensional design, which is an undesired effect. However, in case the player is allowed to decide on which face of a three-dimensional body is used as a receiving part or an intruding part, then the factor which limits the use of the logical toy can be eliminated.
