Definitions

• the invention relates to a toy construction assembly, comprising elongate members which may be interconnected, and especially intended for children and for constructing three-dimensional spatial constructions.
• a construction assembly is known from European patent specification EP-B-0490033.
• EP-B-0490033 European patent specification
• the angle between the elements of the assembly can not be chosen freely and only the ends of the struts may be interconnected.
• the elongate members comprise a rigid central part and two opposite flexible ends, wherein the connection between different elongate members is realized, without separate connectors, by interconnecting the flexible ends of different elongate members or by connecting a flexible end of one elon- gate member to the rigid central part of at least one other elongate member.
• the interconnection of the elongate members is realized simply by knotting together the flexible ends. Because the flexible ends are attached ⁇ directly or indirectly) to the rigid rod-like part, no separate connectors are needed.
• the ends are flexible, the number of degrees of freedom for the interconnection of the elongate members is infinite. Because a flexible end of an elongate member may be knotted to another elongate member at any arbitrary location, also around the rigid part thereof, the connection not neces- sarily is limited to the outer ends of the elongate member. This ultimate feature allows, among others, to assemble one longer elongate member from two elongate members.
• Said connections may be realized by the formation of a knot, such as a half hitch, in a respective flexible end.
• the elongate member may comprise a flexible elongate body constrained in, and projecting from both opposite ends of a stiffer and shorter tube-like body.
• the flexible elongate body may comprise a rope, flexible tube or alike.
• the flexible ends are attached indirectly to the central part.
• the toy construction assembly according to the invention further may be characterized by a flexible outer sheath surrounding the rigid central part and opposite flexible ends .
• the flexible outer sheath may comprise a woven or braided material.
• the flexible outer sheath is filled with a flexible fibre structure which is locally stiffened to a composite by the application of a chemically hardening material or a thermally hardening material.
• the locally stiffening provides at least the rigid central part of the elongate member.
• the planes of an erected construction which is limited by elongate members, may comprise a cloth or foil with holes or eyes with a dimensional system tuned to the elongate members, wherein this cloth or foil is fixed by knotting the flexible ends of the elongate members through the holes or eyes.
• the rigid central part between the two opposite flexible ends may have an arbitrary shape.
• the rigid central part will have an elongate shape.
• Figure 1 shows schematically a first embodiment of an elongate member according to the invention
• Figure 2 shows schematically a second embodiment of an elongate member according to the invention
• Figure 3 shows schematically a third embodiment of an elongate member according to the invention
• Figure 4 shows the interconnection of two flexible ends of two elongate members
• Figure 5 shows the connection of the flexible end of one elongate member to the rigid part of another elongate member;
• Figure 6 shows two elongate members which are knotted together in a parallel manner for realizing an elongate member having a greater length, and
• Figure 7 shows an example of a structure made with the toy construction assembly according to the invention.
• the toy construction assembly comprises elongate members which may be interconnected.
• the elongate members comprise a rigid central part 1 and two opposite flexible ends 2 directly attached thereto.
• the elongate member comprises a flexible elongate body 3 (for example a rope, flexible tube or alike) constrained in, and projecting from both opposite ends of a stiffer and shorter tube-like body 4.
• connection between different elongate members is realized, without separate connectors, by interconnecting the flexible ends 2,3 of different elongate members or by connecting a flexible end 2,3 of one elongate member to the rigid central part 1,4 of at least one other elongate member, see figures 4 and 5.
• the material properties of the flexible ends 2,3 are such, that these may be knotted manually.
• Figure 3 shows another embodiment of the construc- tion element according to the invention, characterized by a flexible outer sheath 5 surrounding the rigid central part 1 (not visible) and opposite flexible ends 2 (not visible) .
• the opposite flexible ends 2 may be omitted, such that the parts of the outer sheath 5 projecting beyond the opposite ends of the central part 1 will define such flexible ends themselves (which, again, are attached indirectly to the central part) .
• the flexible outer sheath 5 may comprise a woven or braided material. Further the flexible outer sheath 5 may be filled with a flexible fibre structure which is locally stiffened to a composite by the application of a chemically hardening material or a thermally hardening material, for example for defining the rigid central part 1 and flexible ends 2.
• Figure 6 shows two elongate members according to figure 1 which by means of the flexible ends 2 are knotted together in a parallel manner for realizing an elongate member having a greater length.
• Figure 7 shows an example of a structure made with the toy construction assembly according to the invention, wherein eighteen elongate members are assembled to a house- like construction.
• Each elongate member may be manufactured from a single material.
• the desired difference in rigidity between the rigid central part 1,4 and the two opposite flexible ends 2,3 may be realized then through a difference in diameter of said parts.
• the elongate members have different lengths and that the rigid central parts 1,4 have different rigidities, such that an infinite number of small and large structures may be assembled.
• the planes of an erected construction (see for example the planes of the construction according to figure 7) , which is limited by elongate members, may comprise a cloth or foil with holes or eyes with a dimensional system tuned to the elongate members, wherein this cloth or foil is fixed by knotting the flexible ends 2,3 of the elongate members through the holes or eyes.
