Description

The proposed utility model relates to elements that need to be connected to each other. According to the claimed technical solution, solid, elastic, inflatable and flexible plastic bodies can be connected through a magnetic connection.

There is a known design part (RU 193528, publ. October 31, 2019 Bulletin No. 31), which is made in the shape of a polyhedron, contains magnets mounted on the face of the polyhedron with the possibility of docking it with another similar part, each face of the polygon contains at least two magnet of different magnetization, while the center of the positive magnetization magnet and the center of the negative magnetization magnet are located on a line parallel to the face of the polyhedron and equidistant relative to the perpendicular to its edge, constructed through the center of the face.

The closest in technical essence is the design part (RU 205734, published 08/03/2021 Bulletin No. 22), made in the shape of a polyhedron, containing magnets attached to the face of the polyhedron with the possibility of connecting it to another polyhedron with a surface similar in placement of magnets. The magnets are placed in the cavities of the polyhedron cover, formed on the edges of the polyhedron, where they can move and rotate freely, providing the ability to dock one polyhedron with another polyhedron, while the cover is made of a material that transmits a magnetic field.

The disadvantage of these technical solutions is the use of a large number of magnets on each face of the prism (in the case of placing magnets on the side faces of the prism).

The claimed utility model solves the problem of connecting solid, elastic, inflatable or flexible plastic bodies through a magnetic connection.

This problem is solved by the fact that a designer part containing a magnet is configured to be connected to another designer part having a magnet, characterized in that it contains a strap attached to the designer part with a pocket in which the magnet is placed.

The technical result provided by the given set of features is the ability to connect the surfaces of parts of the designer, both having the same shape and different in shape, due to the possibility of the magnet “exiting the “boundaries” of the part and due to this connecting with the magnet of another part.

The technical solution is intended for organizing children's leisure, constructing structures in the full height of a child from large parts with a magnetic connection, and also provides for other use cases where it is necessary to connect two parts.

A designer part can be an arbitrary body with a base and sides. The connection of the two parts occurs through magnets attached to straps, which extend the magnet beyond the side and thereby provide a large area for the coupling of the two parts. The straps are made of flexible materials that can be hidden inside a recess in a flat part and do not interfere with the vertical stability of the part.

The inventive device consists of the base of the designer part 1 and a strap 2 with a magnet 3 attached to the base of the designer part (Fig. 1). The magnet is located in pocket (cavity) 4, which is attached to the strap. The magnet moves and rotates freely inside the pocket. The pocket is made in such a way that the magnet does not fall out of it.

The basis of the designer is understood as the part itself, which has a different shape. A designer part can have either one strap with a magnet or several straps over the entire surface of the part.

The ends of the strap are attached to the side edge of the part (attaching the ends of the strap to the base of the part is allowed), while the part may have a recess 5 for placing the strap and an area 6 for attaching the strap to the part (Fig. 2), where h is the smallest thickness of the flat part of the designer (basic thickness).

A constructor part can be a rigid body, an elastic body, an inflatable body and a body of a definable shape. A solid body is a body that does not change its shape under external influence on this body, for example, wood, cardboard, plastic. An elastic body and an inflatable body is a body that changes its shape under external influence on this body and returns to its original shape after eliminating the external influence, for example, polyethylene foam, elastic polyurethane foam, EVA, polyester fiber, inflatable pillow. External influence on the body means physical influence, for example, by human hands on this body. Since this technical solution describes the details of a children's construction set, the external influence on the construction piece is understood as the physical impact of a child aged from 3 to 10 years. A body of a defined shape is a body that partially takes the shape of another body, for example, a body of a defined shape: a blanket. When we place a blanket over another body, the blanket partially takes the shape of the other body. We can give the blanket any shape we want with our hands: crumple it or, on the contrary, straighten it.

A designer part may consist of an external cover, a frame and a filler. The design part may contain any of these components. The outer cover is an elastic, durable and safe woven or non-woven material, such as mixed fabrics (PVC, PU), cotton, polyester, spunbond and similar materials. It is allowed to use a combined cover made of different materials. The frame can be made of metal wire, wood, cardboard, plastic, polyethylene foam, foam rubber, EVA, felt panel, polymer sheet and similar materials. The inner filling is an elastic, durable and safe material, such as EPU, polyester fiber, polyethylene foam, non-crosslinked polyethylene, cross-linked polyethylene, foam rubber, recycled foam, evaplast, foam rubber, plastic, polymer sheet, felt panel and similar materials.

In the claimed solution, to create stable structures, at least one magnetic strap on each face is sufficient (if magnets are placed on the side faces of the part).

The design part can be made in the form of a prism. A prism has thickness. If you place magnets directly on the edge of the prism, then the prisms can be joined only in one plane - in a plane that is a continuation of the plane of the prism. To join prisms in different planes, you need to move the magnet away from the edge of the prism. There is a problem of vertical stability of a designer part when it stands vertically on the edge of a prism. To solve these problems, straps 2 with magnets 3 are attached to the edge of the prism. The magnets are placed in pockets (cavities) 4 connected to the straps. The ends of each strap are attached to the side face or to the base of the prism. The strap with a magnet is hidden in cavity 5. The presence of a cavity is optional.

The connection of the two bodies occurs through straps with magnets attached to the parts (Fig. 3).

Strap 2 consists of one (Fig. 4a) or more (Fig. 4b) tapes and a pocket (cavity) 4 with a magnet 3. One end of the tape is attached directly to part 1, the other end of the tape holds the cavity with the magnet. Attaching the tape to a part or to a cavity with a magnet can be achieved by stitching, gluing, soldering and other methods used for the material used.

Strap material - any flexible, durable, plastic, easily deformable, non-flowing material in everyday conditions: fabric, leather, artificial leather, plastic, latex, rubber, woven elastic, etc. (a combination of the listed materials is allowed). The material of the strap is selected in a practical way and must hold the cavity with the magnet and restore its shape after removing the external physical influence (for example, when the prism is placed on an edge).

The material of the pocket (cavity) is any durable material that transmits a magnetic field (PU, PVC, artificial leather, latex, rubber, spunbond, cotton, etc.) and holds the magnet inside the cavity.

The strap is made of flexible and plastic material, which means that the magnet can be located at many different points, the location of which is limited by the cavity and length of the strap. Many points where a magnet is located form a region in space. Many points where the areas of two magnets touch form the magnet coupling area.

It is possible to place several pockets with magnets on one strap or two pockets: a magnet in one pocket, a ferromagnetic in the other pocket. It is allowed to use one pocket with a magnet in the center of the strap, a pair of pockets with a magnet (or a pair of pockets with a magnet and a ferromagnet) at an equal distance from the center of the strap, an arbitrary number of pairs of pockets with a magnet.

Magnet 3 can move and rotate freely inside the pocket (cavity) 4. When one strap approaches another strap, the magnets create a common magnetic field and under its action the magnets move and self-position inside the cavity and, with direct contact of the cavities, form a coupling.

A neodymium magnet can be used as a magnet; ferrite magnet. The shape of the magnet can be any: ball, square; parallelepiped; cylinder with diametric magnetization. The best results are shown by a parallelepiped with a square cross section and transverse magnetization and a cylinder with diametric magnetization.

The strap tape and pockets (cavities) for magnets can be made of the same material. The tape can be hollow, i.e. form a single cavity (pocket) in which a magnet can be placed.

It is allowed to form recesses 5 (Fig. 1, 2) in the design parts and place straps with magnets in the recesses. The size of the recess should be such that the pocket with the magnet is hidden in this recess.

The number of tapes with magnets depends on the shape and size of the part.

This design of the device makes it possible to reduce the cost of construction parts by reducing the number of magnets used.

Below are examples of implementation of the utility model.
