Abstract

FIELD: consumer goods; cultural and general goods. SUBSTANCE: method for forming a 3D body consists in forming the 3D body of four resilient rings having slots by means of bending, entering other ring followed be resilient straightening. The apparatus for forming a 3D body has four flat rings. Each ring has six cuts made on its external and internal sides. The cut depth is equal to half the ring width; the cut width is equal at least to the ring thickness. The first ring has all six cuts made on the external side; the second ring - on the internal side; the third ring has two cuts made on the internal side and four cuts made on the external one; the fourth ring has four cuts made on the internal side and two - on the external side. The rings are made of resilient material; the external and internal sides of each ring are made in the form of a rectilinear hexagon. EFFECT: increased efficiency of the process. 2 cl, 6 dwg

Description

 The invention relates to objects of cultural purpose, in particular to coasters, stands, and can also be used as a toy or puzzle.

 A known method of forming a three-dimensional body of a flexible tape: tetrahedron, octahedron, etc. [1].

 The disadvantage is the weaving of the tape of large length, increased consumption of material.

 The famous game-pyramid in the form of a three-sided pyramid, assembled from an octahedron and four small pyramids with marking faces.

 The disadvantage is the heavy weight due to the solidity of the volume parts.

 An advertising device is known with a series of metal billboards fastened to each other for placing advertisements on them and a board for installing vases with flowers on it.

 The disadvantage is the complexity of the device.

 A known lamp containing an input optical device and a slit light guide made in the form of friction-fastened flexible strips between them.

 Disadvantages - a large number of stripes, flexibility of form.

 The closest solution to the invention in technical essence is a method of assembling an educational toy from rod elements connected to each other with the formation of a rod frame in the shape of a polyhedron using hinged nodes.

 The disadvantage is the assembly of many rods and hinge assemblies, their adjustment.

 Of the closest analogues, a device for forming a three-dimensional body containing a set of rings is known. In a known object, a three-dimensional body is formed by alternately installing one ring on another.

 The aim of the invention is the expansion of functionality.

 The method of forming a volumetric body is that a volumetric body is formed of four rings of elastic sheet material with radial slots in the desired combination to half the width of the ring by introducing them into each other by elastic bending and straightening with the formation of a lattice body of four flat rings, with this first, before installing one ring in another, the first ring is bent, placed inside the second ring and installed with slots on the outer surface in the slots on the inner surface of the first rings due to the elastic straightening of the second ring, then inside or outside the first two rings, alternately also due to elastic bending and straightening the third and fourth rings.

 This is also achieved by the fact that the device for forming a three-dimensional body contains a set of four rings with six slots made in depth equal to half the width of the ring, and in width not less than the thickness of the ring with the possibility of installing an elastic ring in it, its counterpart, this set rings are elastic, that is, made of elastic material, and on each ring of the set there are six slots on the outer and / or inner sides, namely: either only six outer slots, or six internal slots, or two inside nal and four external slots, or four internal and two external slots.

 In FIG. 1 shows a volumetric body device; in FIG. 2 - the same, top view; in FIG. 3 - hexagon with slots on all diagonals inside; in FIG. 4 - the same, on all diagonals outside; in FIG. 5 - the same, one diagonal inside and two diagonals outside; in FIG. 6 - the same, one diagonal outside and two diagonals inside.

 The method of forming a volumetric body is that the volumetric body is formed of four rings 1 of elastic sheet material with radial slots 2 in the required combination to half the width of the ring, with it being preliminarily bent before installing one ring into another and then placed in the second ring and straighten due to elasticity, installing slots on its outer surface in the slots on the inner surface of the first ring, and then the remaining rings are alternately installed on these two rings. So, for example, a volumetric body can be formed by first installing ring 6 on ring 4, and then ring 5 and ring 3 on them in series.

 A cube-shaped volumetric body with removed corners is made of four hollow elastic hexagons that enter into each other by slots 2, located on one hexagon (ring 3) along all diagonals inside, on the other 4 - along all diagonals outside, on the third 5 - along one diagonal inside and two diagonals outside, on the fourth 6 - one diagonal outside and two diagonals inside, with each slot made half the width of the section of its location and with the possibility of entering the oncoming part. Elastic hollow hexagons (rings 1) can be made of various materials, such as metal, plastic, paper, cardboard, etc., and various colors.

 Work with the device of the volumetric body is as follows.

 A volumetric body is assembled from four hexagons (rings 1) by input into the slots 2, and the assembled volumetric body is mounted on the face in the form of a square or a triangle and used as a decorative body, stand, exhibition or advertising stand, etc., from various materials in whole or in part. During transportation and storage, the bulk body is disassembled by extracting the elastic hollow hexagons (rings 3, 4, 5, 6) from each other to separate parts of the body that are stacked on top of each other.

 The use of a device for forming a volumetric body allows to reduce weight and increase the rigidity of a quick-detachable volumetric body in the form of a cube with removed angles from the same hexagons with corresponding slots, to transport and store at a small volume, to expand operational qualities due to various installation, execution of various materials entirely and according to parts.
