ELEMENT OF CONSTRUCTION KIT (VERSIONS) AND CONSTRUCTION KIT Russian patent published in 2014 - IPC A63H33/08 

FIELD: personal use articles.

SUBSTANCE: construction kit comprises at least three types of elements of the construction kit, made with the ability to connect with each other and to form a unitary structure. The elements of the construction kit of the first type comprise a base formed flat in the shape of a rectangle which sides are multiples of "a", and the connecting node formed by projections located on the basis, forming four groups. In the first group the projections arranged at least on one side of the base, the height of which is more than "0.5a" but no more than "a", are formed with a cruciform cross section in which the distance between the opposite ends of the cross is equal to "a", and/or tubular with the cross section in the form of a ring having an outer diameter which is equal to "a". In the second group the projections located at least on one side of the base, the height of which is equal to "0.5a", are made tubular with a cross section in the form of a square which side length in the tubular projection channel is equal to "a". In the third group the projections are formed as rectangular plates located with their long midline at the base ends flush with these ends and having on the short sides, the width of which is equal to "a", the ledges protruding from the base end not more than by "0.5a" which are inclined to each other to form a gap between their end parts not more than "a". In the fourth group the projections are formed as angle bars, the shelves of which are located perpendicular to the plane of the base at its adjacent ends flush with these ends and having the length equal to "a" and the width not more than "0.5a". The projections are located on the base in accordance with the grid mesh, the mutually perpendicular lines of which are parallel to the edges of the base, and the distance between the adjacent grid mesh lines is equal to "2a", and between the edges and the lines of grid mesh adjacent to them is "0.5a". The projections of the first group are located at the intersections of the grid mesh lines, the projections of the second group - at the intersections of the diagonals of the grid mesh cells, the projections of the third group are located midway between the adjacent projections of the first group located flush with the base ends, the projections of the fourth group - in the corners of the base. In implementing the projections of the first group with a cruciform cross-section flush with the base ends their end parts are located. The construction kit elements of the second type contain three of the four groups of projections listed above. The construction kit elements of the third kind are made tubular and/or rod-shaped and are provided with at least one projection on the lateral surface made with the ability of longitudinal movement of the construction kit elements of the third kind inside the projections with the cross section in the form of a ring when placing the projections of elements of the construction kit of the third type in the grooves of projections with the transverse section in the form of a ring.

EFFECT: enhanced functional capabilities of the construction kit elements by increasing the variants of their connection.
