Description

The invention relates to the field of toy designers and can be used for a fixed detachable connection of two or more voluminous corpulent parts of a toy designer made of foamed polyethylene, plastic or wood, in the process of assembling a variety of toy structures.

A known connection node of two flat parts (Gagin V.V. RU No. 2110315, IPC А63Н 33/08, 1998.05.10) formed by joined parts and a connecting element, which, according to the applicant, is closest to the claimed invention, i.e. . is its analogue.

The disadvantage of the analogue is that it cannot provide a fixed connection of volumetric corpulent parts having the shape of a rectangular parallelepiped or a body of revolution.

The problem to which the claimed invention is directed, is to expand the arsenal of connection nodes of the elements of the toy constructor and to provide the possibility of a fixed detachable connection between two or more voluminous corpulent parts, based on the shape of a rectangular parallelepiped (or body of revolution) with a flat outer surface having no protrusions.

The claimed invention is characterized by the following set of essential features (1st option).

The connection node is formed by joined parts and a connecting element. The connected parts are made full-bodied and voluminous. In the centers of the mating parts, identical through holes of circular cross section are made, oriented with their longitudinal axes perpendicular to the mating planes. The connecting element is made up of one rod part, one end fork part and one end socket part. The rod part is made of a tubular round section with pronounced and coaxial larger upper part and smaller lower part, the radius of the outer surface of which in the plane of its cross section is smaller than the radius of the outer surface in the plane of the cross section of the upper part by the wall thickness of the rod part. The wall of the upper part of the core part is made with m longitudinal oblong cuts, where m is a positive integer forming the upper part of the core part consisting of m petals. On the inner surface of each petal along its open edge, a segment-shaped protrusion adjacent to the end of the petal is made. On the outer surface of the lower part of the core part at its junction with the upper part, an annular recess is made with a section similar to that of the protrusion on the inner surface of the petals of the upper part of the core part. The end fork part is made up of a tubular fragment of circular cross section, similar to the cross section of the upper part of the core part, with the entire body coaxially adjacent to one of its end faces with a flat round solid plate made with pronounced and coaxial large upper part adjacent to the solid plate, and a smaller lower part, the radius of the outer surface of which in the plane of its cross section is smaller than the radius of the outer surface in the plane of the cross section of the upper part of the tube that fragment to the wall thickness of the core part. An annular recess of a segment-like section similar to the section of a protrusion on the inner surface of the petals of the upper part of the rod part is made on the outer surface of the core part in the place of its contact with the upper part of the tubular fragment. The end rosette part is made up of a tubular fragment of circular cross section, similar to the cross section of the upper part of the rod part, with the entire body coaxially adjacent to one of its end sides with a flat, solid plate of round shape, the wall of which is made with m longitudinal elongated cutouts forming the open side of the tubular fragment, consisting of m identical petals, similar to the petals of the core part. On the inner surface of each petal along its open edge, a protrusion of a segment-shaped section is made, similar to the section of the annular recess on the outer surface of the core part. The inner radius of the petals in the plane of the cross section of the open side of the tubular fragment with the petals is equal to the outer radius of the lower part of the core part, with the largest transverse dimension dc of the core part being within

do≤dc <1,1 do, where

do is the largest cross sectional dimension of the through hole.

The longitudinal lengths of the tubular fragment of the end socket part and the upper part of the tubular fragment of the end fork part are equal and constitute ho / 2, where ho is the depth of the through hole of the connected part. The longitudinal length of the upper part of the core part is ho.

The second embodiment of the invention is characterized by the same set of essential features as the first option, and differs from it in that the connection node is formed by n connected parts (n is a positive integer), and the connecting element is made up of (n-1) rod parts, one end plug and one end receptacle.

The third embodiment of the invention is characterized by the same set of essential features as the first option, and differs from it in that the through holes and the connecting element are made with a square cross section.

The fourth embodiment of the invention is characterized by the same set of essential features as the second option, and differs from it in that the through holes and the connecting element are made with a square cross section.

The fifth embodiment of the invention is characterized by the same set of essential features as the first option, and differs from it in that the final fragment of the upper part of the core part with m petals is made with an external radius in the plane of its cross section smaller than the external radius in the plane of the cross section of the middle of the upper parts of the core part, the upper part of the tubular fragment of the end socket part with m petals is made with an external radius in the plane of its cross section smaller than the external radius ca in the plane of the cross section of the middle of the tubular fragment of the end rosette part, the outer radii of the lower parts of the rod part and the end fork part, as well as the inner radii of the final fragment of the top part of the bar part with m petals and the upper part of the tubular fragment of the end rosette part with m petals the planes of their cross sections.

To connect two volumetric solid parts 1, the rod part 2 is inserted into the connecting holes of the connected parts to half. Then, from the side of the open surface of one of the connected parts, an end part 3 or 4 is inserted into its hole, depending on the corresponding end of the rod part (the male part is articulated with a socket and vice versa) and inserted into a fixed connection with the latter. Similarly, the second end part is connected to the rod part 2 from the side of the open surface of the second joined part 1. The flat plates 8 of the end parts hold the joined parts from axial displacement relative to each other, and the fixed connection of the end fork part 3 with the upper part of the rod part 5 and the end socket part 4 with the lower part of the rod part 6 holds the connecting element in assembled form and prevents axial and transverse displacement of the connected parts. The fixing of various parts of the connecting element between each other and with the end parts is carried out by entering the inner protrusions on the petals of the upper part of the rod part 5 and on the end socket part 4 in the annular recesses 7 in the lower part of the rod part 5 and in the lower part of the end fork part 3.

Thus, the claimed invention expands the arsenal of the nodes of the connecting elements of the toy constructor and provides the possibility of a fixed detachable connection between two or more voluminous solid parts made of plastic, wood or foamed polyethylene. The possibility of a fixed detachable interconnection of parts of the toy constructor allows you to create a wide variety of ZD-toy structures that are resistant to destructive influences.
