[Technology]
As is known, several types of toys are commercially available for the purpose of developing the assembly capacity of the elements. In general, the majority of toys carry some degree of complexity that cannot be changed depending on the age of the child. Jigsaw toys are made up of essentially similar individual elements that are connected between themselves by special joints or fasteners.

  The document EP 63816 describes a spatial jigsaw (puzzle) consisting of several solid elements in which one element is placed inside another, which cannot be separated from each other and can move relative to each other. Indicates. The outer spherical element and the inner spherical element have movable symbols. This spatial jigsaw is used to develop patience and stereoscopic views.

  The document WO 9420186 is a sphere (10) composed of several polygonal elements (12), the elements (12) overlapping each other's side walls. 10). Each of the polygonal members has an outer surface having a predetermined shape and a circumferential edge that extends from the outer surface and defines the outer surface. Means are also provided to connect the matching edges of the polygonal part so that a sphere can be formed.

  The document US Pat. No. 5,100,039 shows a toy made from a certain number of different elements that are interconnected to form a sphere. The first part of the element has a pyramid shape with a hexagonal cross section and the other parts of the element, each of which has a pyramid shape with a pentagonal cross section. Corresponding elements are connected in a special way to form a sphere and have protrusions and sockets that overlap one another.

  All of the above references are solid jigsaws of varying difficulty, i.e. solid jigsaws with variations of construction that require more complex skill levels or simpler skill levels when assembled into a sphere, with regard to the age of the child The adjustable jigsaw is not shown. Furthermore, all the literature shows essentially one spherical surface composed of several elements that overlap each other due to the shape of the elements, while the present invention consists of elements that must be assembled. And some spheres have more spheres placed inside other spheres, and all these spheres are free to rotate in all directions, so that the geometry of the spheres during the assembly or disassembly process Develop children's knowledge of the geometrical shape and characteristics of the sphere.

  The object of the present invention is to develop a new assembly of individual elements that can be assembled that not only develops the assembly capability and perspective of the solid, but also changes the difficulty of operation without changing the concept on which the solid jigsaw is based. To create a type of toy.

  The present invention is comprised of several spheres of various dimensions, with one sphere being inside another. Each of these spheres consists of several elements that can be interconnected in a spherical surface, and the spheres can rotate freely in all directions.

  According to one way of implementing the invention, each sphere consists of four geometrically identical elements, while the sphere with the smallest diameter consists of two equal elements.

  According to another way of implementing the invention, the spherical surface can also consist of two geometrically different elements, and the sphere with the smallest diameter consists of two equal elements.

  According to the method of implementing the present invention, the side walls of an element have the same angle, which is the same for all elements. The spheres can have different diameters, but the angle of the side of the element remains the same with respect to the center point of the resulting sphere. The desired dimensions of the outer spherical surface are 100 millimeters to 120 millimeters, while the targeted weight of a fully assembled toy is 150 grams to 200 grams.

It is a figure which shows the final shape of the toy 1 assembled completely. FIG. 4 is a three-dimensional view of a sphere exploded into four component elements 4 according to one method of implementing the present invention. It is a three-dimensional view of the elements of the sphere 2 at various positions. It is a three-dimensional view of an outer sphere composed of two elements. It is a three-dimensional view of the toy in one stage of assembling the sphere. It is a three-dimensional view of the toy in one stage of assembling the sphere. It is a three-dimensional view of the toy in one stage of assembling the sphere. It is a three-dimensional view of the toy in one stage of assembling the sphere. It is a layout and a three-dimensional view of the element 8 of the sphere 7. It is a layout and a three-dimensional view of the element 8 of the sphere 7.

  Referring to the figure, a solid jigsaw is a toy made of several spheres, preferably four spheres of different diameters, where one sphere is located inside another and these spheres are individual elements. These elements can be easily connected so that they form individual spherical surfaces. This solid jigsaw is composed of spherical surfaces of different diameters, preferably four spherical surfaces (1), (5), (6) and (7), which are located inside one spherical surface. Assembled from individual elements, such that the elements form a single spherical surface, wherein the outer spherical surface (1) consists of a housing (3) and an element (2), the housing (3) and Inside element (2) is a smaller diameter sphere (5), inside sphere (5) is an even smaller diameter sphere (6), and sphere (5) and sphere (6) are 4 A sphere composed of two elements (2) and having the smallest diameter basically constitutes a sphere (7) composed of two elements (8, 8 ').

  Reference numeral 1 is achieved by assembling the housing 3, the element 2 and 10 movable elements located inside the housing, ie in the case of the simpler model 6 movable elements in the housing. The final shape of the toy is shown. Individual elements are represented in the form of small elements composed of plastic or similar materials or polyurethane-based foam materials. When the housing 3 and the element 2 are assembled, the housing 3 and the element 2 constitute an outer sphere 1 having the largest diameter. In appearance, these spheres are divided in half by a socket or groove with a depth of 0.5 to 1 millimeter, each half of the sphere being divided into eight identical spherical parts 4, thereby the angle of one spherical part Is 45 °. According to one way of realizing the invention, the element 2 is a spherical part composed of two adjacent spherical parts 4 for the upper half of the sphere and two adjacent parts 4 for the lower half of the sphere. Yes, these spherical parts are shifted by 45 ° between the spherical parts themselves, ie the width of one spherical part (see FIG. 3).

  Within the housing 3 are smaller diameter spheres 5, spheres 6, and spheres 7. The gap between the outer sphere having the largest diameter (housing 3 and element 2) and the sphere 5 is designed to allow the sphere 5 to rotate unhindered in all directions by this gap. Also, the clearance between sphere 5 and sphere 6 and the clearance between sphere 6 and sphere 7 allows each individual sphere to be rotatable in all possible directions within another sphere. The rotation is made possible by the smooth surface of the element made of a given polyurethane-based foam material. When choosing the materials needed for manufacturing, it is noted that the components that make up a jigsaw must possess hardness, smooth surfaces, and good sliding properties, as well as durability against wear and atmospheric effects. I want.

  The sphere 5 and the sphere 6 are composed of four elements or two elements, depending on how the invention is implemented. As can be seen from FIG. 2, according to one method of implementing the present invention, the sphere 5 and the sphere 6 are composed of four identical elements, each element of which is an element 2 already defined for the outer sphere. It has a geometric shape that is identical to the shape.

  According to another way of implementing the invention, the sphere 5 and the sphere 6 are composed of two elements, one of which has the shape of the housing 3 and the other is already geometrically defined with respect to the outer sphere. The shape of the element 2 is shown.

  The smallest diameter sphere essentially constitutes the sphere 7 given that it is regularly composed of two complete elements 8 and 8 '. According to one way of implementing the invention, FIG. 8 shows one complete element 8, which has three equally symmetrically arranged sphere parts (horns). The other geometrically identical elements 8 'are interconnected so that the elements 8 and 8' constitute a sphere. According to another way of implementing the present invention, the sphere can be divided into two pieces that are not geometrically the same, so that the two sphere parts are formed so as to form a complete element, the sphere 7. The surface in between is designed to geometrically overlap one on top of the other.

  The complexity of assembling a solid jigsaw increases with the number of parts that must be assembled, i.e., the number of movable elements disposed in the housing. In addition, the geometric shapes of the elements that are grouped together in a sphere may be different from the above geometric shapes as long as the shapes of the elements allow extraction or assembly of the elements. . Also, the individual movable elements that are arranged in the housing to form a sphere may have different geometric shapes, which also contribute to the complexity of toy assembly. Become. The greater the number of individual elements, the more complicated the assembly is, thereby requiring unique positioning to assemble the final shape of the toy.

  By increasing the opening in the housing and eliminating the socket that causes the optical illusion, it is possible to reduce the level of difficulty in unzipping the target jigsaw. On the other hand, using a more jagged, less regular shaped socket can significantly increase the difficulty of maneuvering the toy. The illustrated invention has three levels, but the number can be increased by reducing the wall width of the individual levels and changing the diameter of the housing. Color also plays a role in determining the complexity of toy assembly or disassembly. Through the mentioned variations, it is possible to create toys suitable for different ages with regard to the difficulty of assembling / disassembling toys.

  Having described and described the present invention by seeking certain desired ways of implementing the invention, those skilled in the art may make various changes in the form and details of the invention without losing the purpose and entirety of the invention. It has been suggested that it can be done. Accordingly, the purpose of protection of the present invention should not be limited by the manner of implementation of the present invention, but should be defined by the appended claims.
