Description

Technical field

The proposed utility model relates to the field of play prefabricated structures made of polymeric material, and can be used for the purpose of entertainment and development of children and is intended for placement mainly outdoors in the open air.

State of the art

The prior art provides a wide range of prefabricated playhouses that are mini-replicas of real houses that allow children to enter the interior space for entertainment and leisure activities.

As a rule, the known structures are too complicated to manufacture and are not intended for outdoor games, or have a low service life and preservation of their original appearance, which is due to their composition and types of decorative design, since the materials used (for example, cardboard) are subject to significant impact. environment and quickly become unusable, for example, due to exposure to precipitation.

For example, a prefabricated children's house is known from the prior art, containing structural elements made of paper (corrugated cardboard) (RU 35239 U1, 10.01.2004). In a well-known solution, all the walls of the house and separately the roof are made of solid rectangular sheets of corrugated cardboard. In the known solution, no means are provided that would allow the structure to be placed outdoors for a long time. So, from claim 3 of the formula of the said patent, it follows that the walls of the house and the roof are made with the possibility of coloring them with pencils and / or paints, from which it follows that initially the structural elements of the house are not painted, i.e. are not protected from external influences. At the same time, there is no information about any means of protecting structural elements in the patent materials.

Also known is a technical solution that is aimed at increasing the strength of the house (RU 168852 U1, 21.02.2017). Known children's house contains the front, side and rear walls, roof, floor, equipped with frames and interconnected fasteners. In the abstract of the said patent, it is noted that the technical result, expressed in increasing the strength of the house, is ensured by the fact that the frames of the front, side and rear walls are made in the form of wooden frames with plywood sheathing.

At the same time, the description of the patent indicates that the achievement of the technical result is achieved by the fact that the frames of the front, side and rear walls are made with a lining with a filler and an outer textile layer.

As in the previous case, the considered solution does not provide means that would allow the structure to be placed outdoors for a long time, and the outer textile layer does not have any resistance to the environment, for example, in the form of precipitation.

Another well-known analogue is the invention (RU 2070083 C1, 06/28/1993), which discloses a game constructor containing a set of planar modules made in the form of non-metallic rectangular perforated panels, each of which has alternating grooves and protrusions on the edges for accommodating connecting rods. The panels are made in the form of corrugated polymer material. The invention relates to toy building kits and constructors and can be used to build various outdoor play spaces and their equipment by children (interior room, apartment, class, shop, etc. and exterior city, street, square, yard, park, etc.) e.) in the conditions of apartments, kindergartens and schools as special equipment for activating gaming methods of education and upbringing.

The disadvantage of this analogue is that it is intended only for premises. In addition to being made of corrugated polymer, the product does not provide protection from environmental conditions.

The closest analogue is a utility model (RU 203852U1, 08/18/2020), which reveals a prefabricated children's playhouse designed to be placed mainly outdoors in the open air. The elements of the house are made of wood board. Structural elements (walls and roof) are printed with images (on one or both sides of the sheets) made using a color printing method that is resistant to environmental influences, such as ultraviolet printing, sublimation printing or thermal transfer.

In the claimed utility model, the author proposes to apply images by color printing on a polymer material. Since a polymer board is lighter than a wood board, it is easier and more comfortable to assemble such a product. A house made of polymer elements is more moisture resistant than a house made of wood board, so the product is even more protected outdoors. Another important aspect for the production of the product: the polymer is cheaper and more technologically advanced than the wood board. The pattern applied to the polymer material by color printing retains color for a long time, which increases the life of the product.

The proposed utility model provides the achievement of a technical result, which consists in increasing the reliability of the structure for outdoor use, namely durability.

The advantage of the claimed utility model is that the polymer material is more impermeable to environmental conditions than wood, plywood or chipboard, and therefore more reliable. Also new is the application of an image to a polymer material by color printing.

According to GOST 27.002-89 "Reliability in engineering", the term "reliability" is understood as a complex property, which, depending on the purpose of the object and the conditions of its use, may include reliability, durability, maintainability and persistence, or certain combinations of these properties. Applicable to the claimed solution, reliability is understood by the applicant as an increase in the durability of a children's playhouse intended for placement mainly outdoors in the open air, which is expressed in the fact that the house, unlike analogues, is made of polymer plates with images printed on them, made by the color method. print.

Polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polycarbonate (PC), polyethylene vinyl acetate (EVA), polyvinyl chloride (PVC), copolymer of acrylonitrile with butadiene and styrene (ABS), high-impact polystyrene (PS) are used as the material of the polymer plate. ), polymethyl methacrylate (PMMA).

The following section of the description provides information showing how it is possible to implement the utility model with the achievement of the specified technical result.

Implementation of the utility model

It is known that polymer plates - polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polycarbonate (PC), polyethylene vinyl acetate (EVA), polyvinyl chloride (PVC), acrylonitrile copolymer with butadiene and styrene (ABS), high-impact polystyrene (PS ), polymethyl methacrylate (PMMA) are materials produced synthetically based on the simplest compounds of elements of natural origin by polymerization, polycondensation and chemical transformations. The result is products with high performance.

Thus, it is known that a polymer is a substance of "monomeric units" connected into long macromolecules. Due to the polymericity (multiplicity) of the structure, the quality indicators of the product increase. With a small thickness and weight, the strength of a polymer sheet with a certain thickness is several times higher than the strength of a solid wood material of a similar thickness.

Polyethylene (PE) is a synthetic polymer characterized by thermoplasticity and chemical resistance.

Polypropylene (PP) is a synthetic polymer characterized by thermoplasticity and chemical resistance.

Polyethylene terephthalate (PET) is a synthetic polymer characterized by thermoplasticity and polyester properties and is easy to process.

Polycarbonate (PC), polyethylene vinyl acetate (EVA), polyvinyl chloride (PVC), acrylonitrile-butadiene-styrene copolymer (ABS), high-impact polystyrene (PS), polymethyl methacrylate (PMMA) are synthetic polymers characterized by thermoplasticity and resistance to external influences.

The noted properties of the performance of the polymers used for the plates of the product in the proposed utility model were the basis for their use in the implementation of assembly operations between structural elements, chemical resistance ensures the effective acceptance of applied seals and paints by the surface.

The utility model is illustrated by the following figures:

Fig 1 - General view of the house;

in fig. 2 - front view

in fig. 3- rear view ¾;

in fig. 4 – right side view;

in fig. 5 - shows the fastening of the elements of the house.

The main elements of the prefabricated house include: vertical (side) walls 1, horizontal walls 2, gable roof 3, rectangular fixing elements 4, corresponding slots 5 and base 6.

Polymer plates (sheets) for the production of house elements are made by any known method: by extrusion, or by calendering, or by pressing, or by sintering, or by block polymerization.

In the presented embodiment of the utility model, the structural elements are made of a polymeric material, and the image of the picture is made by ultraviolet printing on both sides of the structural elements.

From the presented examples, it is obvious to a specialist that the possibility of using polymeric plates and color printing is variant.

Assembly of the house can be carried out, for example, as follows. Assembly sequence options may differ depending on the number of people who assemble the house.

On a flat surface, the base 6 is placed, one of or several vertical (side) 1 or horizontal 2 walls are brought to a vertical position. The slots 5 on the structural element - sheets of the side (s) walls or / or the roof are aligned with the corresponding rectangular elements 4 and the fastener is passed through the corresponding slot with a mechanical force until the plane of the sheet is aligned with the edge part of the vertical or horizontal walls. The sheet(s) of the vertical wall(s) or roof are then mechanically displaced. The parameters of the rectangular fasteners are selected depending on the thickness of the polymer plate in such a way that after the implementation of these operations, the connected structural elements do not have free play. For example, the slot width may be chosen to be equal to or less than the thickness of the resin board. The choice of this parameter, as well as the choice of the width of the slot to ensure displacement while maintaining the required parameters of the product (for example, so that there are no gaps in the form of slots between adjacent sheets of the polymer plate) is not difficult for a specialist.

In the event that the side walls and/or roof slopes (each of them) are made of several polymer boards, the rectangular elements and slots on the polymer boards are placed accordingly.

If the front or rear walls are made of two parts, the proposed solution provides for the possibility of connecting such parts to each other by means of a polymer plate plate and fasteners with self-tapping threads. For example, a plate is used as an overlay on both parts of the walls and is attached to both walls by means of self-tapping screws.

In addition, the claimed solution provides that the structural elements (base, walls and roof) are printed with images (on one or both sides of the sheets) made by color printing that is resistant to environmental influences, for example, ultraviolet printing, sublimation printing or thermal transfer .

It should be noted that these features are not aimed only at achieving a result that could be recognized as increasing entertainment or satisfying aesthetic needs, although it does not exclude it. In addition, the applied printing serves as an additional layer of protection of the polymer plate from external influences, and therefore increases the reliability of the product.

In the prior art, ultraviolet printing (UV printing) methods are known, in accordance with which specialized dyes are used that quickly harden under the influence of ultraviolet radiation. Like standard inks, UV inks contain resins and pigments. But instead of solvents, they contain monomers and oligomers - small carbon molecules that have the ability to form into long chains that form polymers. If polymers are like a chain, then the monomers that provide properties are like links in that chain. To activate the formation of the chain, especially light-sensitive components called photoinitiators are added to the UV ink. The curing process is called polymerization.

Polymerization of UV inks under ultraviolet radiation irreversibly changes their internal structure - monomers in one polymer chain begin to bind to similar monomers in an adjacent chain, forming a network. An important feature of UV ink is that during curing, almost the entire ink layer turns into a solid substance - a polymer. The resulting UV image is resistant to friction, hand holding, humidity, temperature changes and other environmental factors. Possessing good adhesive properties, UV ink penetrates well into the structure of polymer plates and, during polymerization, reliably protects the structure from precipitation, while giving additional strength to polymer plates.

Another method of transferring the image of a picture onto polymer plates, which was not previously used in the production of a children's polymer playhouse, is sublimation printing. The method is based on the sublimation of the coloring matter, which, when heated, first turns into a gaseous, and then into a solid state. For application, a heat press is used, which heats the surface of the material. The paint falling on it is firmly soldered to the surface, forming a layer that is resistant to mechanical stress. Such images are distinguished by a very high resistance to operation.

A variation of sublimation is thermal transfer, in which high-quality full-color images are transferred, including onto non-woven materials. The first stage of the technology is printing on thermal transfer paper. The paper is a two-layer sheet. The top layer is a thin, temperature-sensitive film. The bottom layer is a dense paper substrate, which holds the film before heating, and when heated is separated from it and removed, and the film is soldered to the material. After printing, the sheet is dried, then transferred to a polymer plate.

Since these methods of transferring the image of pictures on a polymer plate are not the subject of legal protection and are known from the prior art, the process of applying them to a finished house or prefabricated elements of a house does not require disclosure in this application.

Thus, in the proposed utility model, the application of environmentally resistant color printing images to structural elements provides increased protection of the structure from the effects of precipitation, temperature changes, humidity, and other environmental influences.

Therefore, the execution of structural elements from polymer plates and the application of images made by the method of color printing resistant to environmental influences on the elements is essential to increase the reliability of the operation of the erected house in the open air, and increase the durability of the product. Additionally, it should be noted that the image obtained by this method looks realistic and bright, while coloring substances, due to the absence of solvents, do not harm the environment. An outdoor playhouse made of polymer boards is easier to assemble and cheaper compared to its counterpart made of wood boards.
