Description

Technical field

The invention relates to the field of manufacturing and modeling of various objects and products intended for interior decoration.

State of the art

It is known from the prior art to carry out various types of interior items, such as toys, dolls or figures, lampshades for lamps, etc., in the manufacture of which materials such as, for example, various types and types of woven and non-woven materials are used; fibrous materials such as flax, sisal, which is a tough, coarse natural fiber obtained from agave leaves; thread, wire.

So, from patent GB 941204 A, 11/06/1963, A63H 3/16, a method for manufacturing figures is known where the wire is used as a rigid base (frame) of the product, on which, for example, sisal fibers are applied by braiding to form the desired shape of the product.

The closest in essence and the technical result achieved is the method according to the patent US 5975981 A, 02.11.1999, A63H 3/00, from which it is known to manufacture a decorative product, a doll, where sisal fibers are applied to a rigid metal frame to form a three-dimensional figure of the doll, which in point places, for example along the edges of limbs, dolls are fixed with a wire.

The main disadvantage of these methods is the insufficient durability of the product due to the loss of sisal fibers in their original form.

The fundamental difference between the claimed method and the known ones, where, for example, threads are used, is the use of twisted broth wire, which allows the mold to be made more plastic and gives the frame frame rigidity.

SUMMARY OF THE INVENTION

The task to which the claimed invention is directed is the creation of such a technology in which the manufactured product is able to maintain a given shape throughout the entire life cycle.

The problem is solved due to the fact that in the method of manufacturing a decorative product, such as a figurine or doll, including the manufacture of a rigid frame, fixing the base of sisal with wire, according to the invention, the bundle of sisal fibers is pre-knitted and disassembled into fibers, form a preliminary, rough three-dimensional shape of the product , which is an internal non-rigid frame, after which, with the help of a spring metal wire, broths, starting from the geometric center of the product, in any direction, across forms, carry out the initial chaotic laying of the wire by braiding on the formed volumetric shape of the product with the complete passage of all its parts and at the same time supplement, in those places where it is necessary to give the product a more voluminous, embossed shape, in comparison with the rest of its parts, the specified number of sisal fibers then by the "eight" method from the place where the first layer of wire was applied, in an arbitrary direction, also over the entire volume of the product, the wire is re-applied, followed by m and its fixing with the final formation of a continuous homogeneous surface or partially solid hard metal outer carcass over sisal fibers, after which the product is applied on the binder layer and heated until it completely dry.

In the particular case of execution, for example, an acrylic varnish or a mixture of water and PVA glue in a ratio of 1: 9 to 1:11, preferably 1:10, is used as a binder.

The diameter of the wire-broth is 0.1 ÷ 0.8 mm, more preferably 0.4 mm

The wire is colored.

The technical result of the claimed invention is to increase the durability and service life of the product by creating a more rigid structure.

Information confirming the possibility of carrying out the invention

The method is implemented as follows.

For the manufacture, for example, of an interior figurine, they take natural fiber - sisal, straighten and fluff its fibers. After that, from these fibers, manually, an approximate three-dimensional shape of the figure is formed, which is a soft (non-rigid) basis (inner frame) of the future product. Next, they take a spring metal wire - a broth, with a diameter (thickness) of 0.4 mm, which is a tube 300 mm long assembled into an annular spiral and a ring diameter of 1 ÷ 3.5 mm, stretch it in length until a wavy surface forms. It should be emphasized that the name of the wire: "broth" is an established technical term, widely known to specialists in the field of decoration, identified by this name, as a copper colored spiral wire.

Starting from the geometrical center of the figure, in any direction, primary chaotic laying of the wire (by braiding) is carried out on the inner frame formed from sisal fibers with the complete passage of all its parts. At the same time, in those places where it is necessary, in order to give the product a more voluminous shape, in comparison with the rest of its parts, the required amount of sisal fibers is added. The required number of fibers is regulated by the initial final form of the product. Then, using the G8 method, the wire is re-applied, also over the entire volume of the figure, with the final formation of a solid or partially continuous external rigid metal frame over the sisal fibers. With a continuous frame, the surface should be uniform. After braiding, a layer of a binder, for example, a mixture of water and PVA glue in a ratio of 1:10, is applied to the figure made in this way. The indicated range is dictated by the fact that when the ratio of glue and water is less than 1: 9, a sufficient degree of adhesion will not be provided, and if the ratio is more than 1:11, clots can form due to insufficient dilution of the glue with water.

The use of the specified type of wire with the above diameter will provide the necessary stiffness of the product while at the same time simplicity and ease of use. If the wire thickness is less than 0.1 mm, its sufficient strength during winding will not be ensured, and if the thickness is more than 0.5 mm, the complexity of braiding the product with it increases, and the inner frame is deformed due to an increase in wire resistance, especially when the wire is applied occurs with the formation of a continuous surface.

In the manufacture of more bulky products, for example with a height of more than 400 mm, it is possible to use an internal rigid frame made of aluminum wire with a diameter of up to 4 mm or other materials: plastic or wooden inserts. The specified frame can extend, as the entire internal volume, for example for the manufacture of lampshades, lamps, and part of the volume. In the latter case, these are the parts of the product that require additional reinforcement due to the rather thin structural volume at this place and at the same time when these parts account for the bulk of the product, for example, when the bearing of the product is made in the form of a figure or dolls, the surface occurs through the limbs, which are made much thinner and lighter than the rest of the product.
