Description

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

Known connection node of at least two parts of the designer, containing two interacting connection elements, each of which is made on the corresponding parts 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 task the real utility model is aimed at is to develop a knot for connecting designer parts that has advanced technical capabilities that make it possible to form a wide range of spatial three-dimensional figures or models on its basis, while ensuring increased safety during its use by children, especially young children, during design and subsequent games using assembled figures.

The technical result is to ensure rigidity and reliability of the connection of three-dimensional figures, which can withstand various loads from its own mass without changing the spatial shape of the assembled model, as well as to ensure the repeatability of the processes of assembly and disassembly of the models.

Utility Model Essence

To achieve a technical result in solving the problem in a known designer, containing at least two parts interacting with each other by connection elements, each of which is made on the corresponding designer part, one connection element has a hole, and the other has a protrusion, a part with a protrusion made flat of elastic foam or foam rubber with an apparent density of 0.015 - 0.22 g / cm, and the protrusion is made in the form of two parts located at a distance from each other with the possibility of formation spatial figure when connecting both parts of the protrusion to each other

Technical field

State of the art

A part with a protrusion may have cuts and cuts to form a spatial figure.

These signs are essential and interconnected causally with the formation of a set of essential features sufficient to achieve the specified technical result of the spatial figure.

Brief Description of the Drawings

In FIG. 1 shows one of the details of the designer with the nodes of the connection,

in FIG. 2 - connection of two parts,

in FIG. 3 is a side view of the part shown in FIG. 1 in the folded position.

The useful model is illustrated by a concrete example of implementation, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving this set of features of a technical result.

The connection node of at least two parts 1 and 2 of the constructor (Fig. 1,2) 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. At the same time, the protrusion 4 is placed in the hole 3 with an interference fit.

Part 2 with a protrusion 4 is made flat of elastic foam or foam rubber with an apparent density of 0.015 - 0.22 g / cm.

The protrusion 4 is made of two parts 5 and 6 located at a distance from each other with the possibility of the formation of a spatial figure (Fig.Z) when connecting both parts of the protrusion to each other and fixing it in the hole 3 of the other part 1 with an interference fit.

The interference fit, determined by the positive difference between the size of the hole and the protrusion of the corresponding connection elements, is in the range of 0.002 - 10 mm, which increases the reliability of the connection, and the ductility of the material provides little effort during assembly.

At the junction, at least one of the elements of the connection 3 or 4 can be made in one piece with part 1 or 2.

Detail 2 with the protrusion 4 may have additional connection elements in the form of protrusions 7 and holes 8.

The protrusion 4 can be performed with an axial displacement clamp, which is the shoulders 9, made on parts 5 and 6 of the protrusion 4. The part 2 with the protrusion 4 may have an additional connection element in the form of open holes 10. The interference is in the range of 0.001 - 10 mm. The detail 2 with the protrusion 4 may have notches 11 and notches 12 to form a spatial figure.

The connection elements are made of flexible foam with an apparent density of 0.015 - 0.22 g / cm, which can be: polyurethane foam, expanded polystyrene, expanded polystyrene chloride, expanded polyolefins, foam foams or foam rubber with an apparent material density of 0.015 - 0.22 g / cm . The use of the above polystyrene foams on the one hand eliminates the possibility of injuries 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 different shapes 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 lower 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 Implementation Example

The utility model meets the criterion of industrial applicability, since its manufacture is possible using existing means of production using limestone technology.
