CONNECTION NODE

Technical field

The utility model relates to light industry, namely to the nodes of compounds in the means of construction and modeling of soft soft material intended for the development of creative skills in children.

State of the art

Known is the junction of at least two parts of the designer, containing two interacting; they are interconnected elements of connection, each of which is made on the corresponding part of the designer, while one connection element has a hole and the other a protrusion (US 3811219 class A 63 H 33/08, publ. 05.21.1974).

However, such a designer has limited technical capabilities and is dangerous for children, since the material used for their manufacture is hard and has sharp angles that cause various injuries during the game.

The objective of which the present utility model is directed is to develop a knot for connecting designer parts that has advanced technical capabilities that allow it to be formed on the basis of a wide range of spatial figures or models, while ensuring increased safety during its use by children, especially young children, during construction and subsequent games using assembled figures.

Brief Description of the Drawings

In FIG. 1 schematically shows a first embodiment of a unit for connecting parts of a designer,

figure 2 - the second embodiment of the zzl connection, -.

figure 3.4 is a third embodiment of a connection node.

Useful to fashion; n is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving a given set of features of a technical result.

According to the first embodiment, the connection node of at least two parts 1 and 2 of the constructor (Fig. 1) contains two interacting connection elements, each of which is made on the corresponding part 1 or 2 of the constructor. One connection element is a hole 3, and the other is a protrusion 4. On opposite sides of the protrusion 4, transverse grooves 5 are made to surround the protrusion 4 with an interference fit of the connection element with the hole 3.

According to the second embodiment, the connection unit of at least two parts 1 and 2 of the constructor (Fig. 2) contains two interacting connection elements, each of which is made on the corresponding part 1 or 2 of the constructor. One connection element is a hole 3, and the other is a protrusion 4. On opposite sides of the protrusion 4, transverse grooves 5 are made to surround the protrusion 4 with an interference fit of the connection element with the hole 3, which is open in part 6.

According to the third embodiment, the connection unit of at least two parts 1 and 2 of the constructor (Fig. 3) contains two interacting connection elements, each of which is made on the corresponding part 1 or 2 of the constructor. One connection element is a hole 3, and the other is a protrusion 4. On opposite sides of the protrusion 4, make transverse grooves 5 to enclose the protrusion 4 with an interference element of the connection with the hole 3, which is open in part 6. The connection unit is provided with a second connection element 7 with hole 8, which is also made open in part 9, and the open parts 6 and 9 of the connection elements with holes 3 and 8 are directed in different directions.

The elements of the joint are made of flexible foam or foam rubber with an apparent density of 0.015 - 0.22 g / cm. As the foam can be applied: polyurethane foam, polystyrene foam, polyvinyl chloride foam, polyolefins, foam foams with an apparent material density of 0.015 - 0.22 g / cm. The use of the above polystyrene materials on the one hand eliminates the possibility of injury both during the assembly process of the designer and during the game with assembled models, and on the other hand, the use of these materials expands the technical capabilities by obtaining a wide range of various figsf using well-known cutting methods that allow in turn, the creation of models of complex shape, as close as possible to real-life objects.

The change in the apparent density of the elastic porous material in the direction of increase leads to an unreasonable increase in the consumption of material, the difficulty of designing in the manufacture of figures of complex construction and increasing energy costs. The null limit of the apparent density of the material is due to the impossibility of forming spatial figures, which should have a bearing capacity.

Utility Model Reap Example

The utility model meets the criterion of industrial applicability, since its manufacture is possible using existing means of production using well-known technologies.
