Description

Technology area

The proposed utility model relates to the field of large-sized prefabricated play structures, can be used for the entertainment and development of children and is intended to be placed mainly outdoors in the open air.

State of the art

The prior art presents a wide range of prefabricated playhouse structures that are mini-replicas of real houses that allow children to enter the interior for entertainment and leisure.

As a rule, the known structures have an excessive complexity of manufacture and the duration of the subsequent assembly, mainly due to the presence of a large number of parts and, accordingly, the assembly operations required to bring the houses into a ready-to-use state.

The same designs that involve the use of a small number of parts are often not designed for outdoor use due to the fact that the materials used (for example, cardboard) are significantly affected by the environment and quickly deteriorate, for example, due to the effects of 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 the known solution, all the walls of the house and the roof separately are made of solid rectangular sheets of corrugated cardboard, the gables are made with tongues for fastening the roof when assembling the house, and slot-like holes are made in the roof for passing the tongues of the pediments through them and next to each of these holes there are holes parallel to the latter for fixing the ends of the gable tongues, and at least one transverse slot-like slot is made on the gable tongues.

The disadvantages of the known solution include the low reliability and complexity of the fastening elements, since the fastening elements involve repeated threading of the tongues into the slot-like holes, as well as the use of the bearing properties of corrugated cardboard, which, as you know, does not have any significant bearing capacity.

In addition, the known solution does not provide for means that would make it possible to place the structure in the open air for a long time. So, from clause 3 of the formula of this 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, information about any means of protecting structural elements is not contained in the materials of the patent.

A technical solution is also known that is aimed at increasing the strength of the house and can be chosen as the closest analogue of the proposed utility model (RU 168852 U1, 02.21.2017). A well-known children's house contains a front, side and back walls, a roof, a floor, provided with frames and interconnected by fasteners. In the abstract of this patent, it is noted that the technical result, expressed in increasing the strength of the house, is provided 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, in the description of the patent it is indicated 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 skin with a filler and an outer textile layer.

In addition, as fastening elements for connecting structural elements to each other, the patent notes the use of furniture velcro, which obviously do not have stability and reliability of fastening, in the case when massive structural elements (in particular, plywood sheets) are to be connected.

Thus, it can be argued that in the known solution there is no causal relationship between the increase in strength and the use of wooden frames with plywood sheathing.

Just as in the previous case, the considered solution does not provide for means that would allow the structure to be placed in the open air for a long time, and the outer textile layer does not have any resistance to environmental influences, for example, in the form of precipitation.

The proposed utility model is aimed at overcoming the noted drawbacks of the prior art and ensures the achievement of the technical result, which consists in increasing the reliability of the structure for the purpose of outdoor operation, namely, its durability.

According to GOST 27.002-89 "Reliability in technology" 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 preservation, or certain combinations of these properties. Applicable to the declared solution, the applicant's reliability means 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 its analogue, is made of a wood board with images applied to it made by the color method print.

Disclosure of a utility model

To achieve the above technical result, a prefabricated children's playhouse is proposed, containing structural elements: walls and a roof, interconnected by fasteners, characterized in that the walls and roof are made of wood board with images applied to it, made by color printing.

The fastening elements are protruding hook-shaped elements made on the edge parts of the walls, and the corresponding slots are made on the structural elements intended for connection.

In a further embodiment of the image, ultraviolet printing is used to transfer the image to the wood board.

In a further embodiment of the image, sublimation printing is used to transfer the image to the wood board.

In a further embodiment of the image, thermal transfer is used to transfer the image to the wood board.

Images are located on one or both sides of the structural elements.

Plywood, chipboard, fiberboard, MDF, laminated chipboard are used as a sheet of wood board.

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

Implementation of the utility model

It is known that wood-based panels - plywood, chipboard, fiberboard, MDF, laminated chipboard - are materials produced on the basis of natural wood with various additives: mineral binders, synthetic resins, etc. The result is high performance products. Wood boards retain all the advantages of natural wood and, at the same time, are practically devoid of its disadvantages.

So, it is known that plywood is a multilayer building material that is made from wood veneer. Due to the multilayer structure, the quality indicators of the product are increased. With a small thickness and weight, the strength of a plywood sheet with a certain thickness is several times higher than the strength of a solid wood material. This is due to the fact that the veneer is glued so that the fibers of each layer are perpendicular to each other, as a result of which the strength of the plywood structure is much higher.

Particleboard (chipboard) is a composite sheet material, for the production of which a mixture of sawdust and a binder is used. Wood chips are combined with urea-formaldehyde and phenol-formaldehyde resins, thoroughly mixed and processed under the influence of high temperature and pressure, due to which chipboards have high strength, superior to those of natural wood, good water resistance due to the presence of synthetic resins in the material.

Fiberboard (Fibreboard) is made from wood fiber mass by hot pressing. The fibers adhere to each other due to the main property of the pulp - the ability to interweave and felter. Fiberboard is durable, retains its appearance and properties even at high humidity, does not swell after being in water.

MDF board (finely dispersed fraction) is made from sawdust by pressing under high pressure. In its manufacture, the smallest particles are used. It differs from other similar materials in a fundamentally new composition of the glue, which includes such natural resins as paraffin and lignin. This increases the density, strength and moisture resistance of the material.

Chipboard is a laminated chipboard made on the basis of coarse wood chips, bonded with formaldehyde resins. The surface of the board is treated with a polymer film, thanks to which the board is protected from moisture. Other advantages of the board are environmental safety, strength, good performance. MDF boards are resistant to high humidity conditions, as well as to temperature changes, mold, harmful microorganisms and fungi.

The noted properties of the performance characteristics of wood-based panels in the proposed utility model were the basis for their use in the implementation of assembly operations between structural elements.

Embodiments of the invention are shown in FIGS. 1-6, where FIG. 1, 4 is a general view of a prefabricated children's playhouse without color printing, FIG. 2, 5 - shows the prefabricated elements of the house, made of wood-based panels; in fig. 3, 6 - finished houses with color printing.

The main elements of the prefabricated house include: front wall 1, side walls, including top 2 and bottom 3 panels; back wall 4; gable roof 5; fastening hooks 6; the corresponding slots 7 and the connecting panel 8.

In the presented embodiment of the utility model, the structural elements are made of plywood, and the image of the picture is printed on both sides of the structural elements.

Another embodiment of the utility model (Fig. 4-6) is made of a wood board - chipboard and includes front, rear, side walls made in the form of a single panel and a pitched roof. The image of the picture on the chipboard is applied by sublimation printing.

From the presented examples, for a specialist, the possibility of a variant use of wood-based panels and color printing is obvious.

The assembly of the house can be carried out, for example, as follows. Assembly sequence options may vary depending on the number of people assembling the house.

On a flat surface, bring one of or simultaneously both front 1 or back 4 walls to a vertical position. The slots 7 are aligned on the structural element - the sheets of the side (s) walls or / or the roof with the corresponding hook-shaped elements 6 and mechanically thread the hook horn into the corresponding slot until the plane of the sheet aligns with the edge part of the front sewn of the rear walls. Then, by mechanical force, the sheet (s) of the side wall (s) or roof is displaced so that the mouth of the hook is aligned with the edge of the slot. In a preferred embodiment, the mouths of the hooks with are directed towards an increase in height, thus, the displacement of sheets with slots is carried out towards a decrease in height. The parameters of the hook-shaped elements (in particular, their throat) are selected depending on the thickness of the wood board in such a way that after the implementation of these operations, the connected structural elements do not have a free run. For example, the width of the throat can be chosen equal to or less than the thickness of the wood board. The choice of the specified 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 gaps between adjacent sheets of wood board) is not difficult for a specialist.

In case the side walls and / or roof slopes (each of them) are made of several wood-based panels, hook-shaped elements and slots on the wood-based panels are appropriately placed.

In the event that the front sewn back walls are made of two parts, the proposed solution provides for the possibility of connecting such parts to each other by means of a plate made of wood board and fasteners with self-tapping threads. For example, the plate is used as an overlay on both sides of the walls and is attached to both walls by means of self-tapping screws.

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

It should be noted that these signs are not only aimed at achieving a result that could be recognized as increasing the spectacle or satisfying aesthetic needs, although it does not exclude it.

Ultraviolet printing (UV printing) methods are known from the prior art, in accordance with which specialized dyes are used that quickly solidify 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 the polymers are like a chain, then the monomers that provide the properties are like the links in that chain. To activate chain formation, ultra light sensitive components called photo initiators are added to the UV ink. The curing process is called polymerization.

Polymerization of UV ink under ultraviolet radiation irreversibly changes their internal structure - monomers in one polymer chain begin to bind into 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-printed 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 wood-based panels and reliably protects the structure from precipitation during polymerization, while giving additional strength to the sheets of wood-based panels.

Another method of transferring the image of the picture onto wood-based panels, which was not previously used in the production of a children's playhouse, is sublimation printing. The method is based on the sublimation of a dye, 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 their very high resistance to exploitation.

A type of sublimation is thermal transfer in which high-quality full-color images are transferred, including onto nonwoven 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 backing, which holds the film before heating, and when heated, it is separated from it and removed, and the film is soldered to the material. After printing, the sheet is dried, then transferred to the wood board.

Since these methods of transferring the image of pictures to a wood board are not subject to 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 on structural elements of images made by color printing, resistant to the action of the environment, provides increased protection of the structure from the effects of precipitation, temperature drops, humidity, and other environmental influences.

Consequently, the implementation of structural elements from wood-based panels and the application of images made by the method of color printing to the elements, resistant to the actions of the environment, is essential to increase the reliability of the operation of the erected house in the open air. Additionally, it should be noted that the image obtained in this way looks realistic and bright, while the dyes, due to the absence of solvents, do not harm the environment.
