Abstract

FIELD: human vital needs satisfaction.

SUBSTANCE: essence of the proposed method of changing the length of the working part, as well as the contour of the end part of the hair bundle of the art brush, consists in rigidly fixing the flattened hair bundle in the fastening element, to reinstall the shape of the hair follicle exhibition, the rigid attachment of the hair bundle (during the change in its characteristics Shape of the terminal portion of the flattened hair set). The implementation of the proposed method is carried out as follows. As an element that provides both a rigid fixation of the bundled hair bundle and the elimination of rigid attachment of the hair bundle, a thermoplastic glue 5 is used (the amount of glue 5 is determined experimentally). It at room temperature rigidly fixes the flattened hair bundle 3 of the art brush, when melting the thermoplastic glue 5, rigid fixation of the flattened hair bundle 3 is eliminated. For the melting of the adhesive, for example, a thermoset can be used (in fig. 1, 2 is not shown) with the brush set in the position shown in fig. 1, 2 (in order to exclude the loss of the end set 3 from the cage). When the glue is in the liquid state, the user is provided with both an exhibition of height and an exhibition of the shape of the end part of the flattened hair bundle 3 without the use of templates or with such (the template is not shown in the drawings). In this case, it is necessary to comply with safety techniques, since the work is done with hot objects. For example, work should be done in thermo-gloves. To exclude changes in the colour of hairs, deterioration in their quality, as well as the quality of the coating pen and holder, etc. the melting point of glue 5 should not be more than 70-80°C. In this case, the smaller the melting temperature of the thermoplastic glue 5, the safer it will be to work with it. After the exposure of the hair bundle 3, the glue 5 is cooled, the hair bundle 3 is rigidly fixed in the cage 1.

EFFECT: expansion of functionality due to the possibility of multiple changes in the length of the working part, as well as the contour of the end part of the hair bundle of the artistic brush in the process of its operation without violating the integrity of the clip.

Description

The invention relates to methods for changing the contour of the end part of a hair bundle of art brushes used in artwork and other brushes used for drawing and creativity.

There is a method of changing the length of the working part of the connected hair bundle of the brush, which consists in rigidly fixing the connected hair bundle in the fastener, while to change the length of the working part of the connected bundle, the rigid fastening of the hair bundle for the time of changing its characteristics is excluded (see patent SU 724120, 1980 )

The disadvantage of this method is its limited capabilities, since this method does not allow changing the shape of the end part of the hair bundle.

The art brush is known from the prior art, containing a fastening element, on the one hand rigidly fastening the handle, on the other hand, an end set of hairs fixed in a clip with glue (see patent RU 2036802, 1995).

Also known from the prior art bonding of hairs with glue (see patent RU 2448624).

The technical result of the invention is the expansion of functionality by providing the possibility of multiple changes in the contour of the end part of the hair bundle of an art brush during its operation without violating the integrity of the clip.

The technical result is achieved by the fact that to enable multiple changes in the contour of the end part of the hair bundle of the art brush during its operation without violating the integrity of the clip, a method is proposed that consists in rigidly fixing the hair beam in the clip, the inner cavity of which does not cover the handle, is made in the form containers, to change the contour of the end part of the hair bundle of an art brush, thermoplastic glue is placed in the container, holding it in a solid When the working position of the hair bundle is thawed, the thermoplastic glue is brought into a liquid state by heating it at the time of changing the contour of the end part of the brush.

The invention is illustrated by drawings, where, as an example in FIG. 1 and 2, a flattened set of hairs was taken (Fig. 2 shows a view from the right side in Fig. 1). Position 1 shows the clip; position 2 - a handle, position 3 - a set of hairs (flattened hair set); position 4 - capacity in the cage 1, position 5 - thermoplastic adhesive. In FIG. 3 to 9 show various possible embodiments of the contour of the working part of the artistic brush. In FIG. 3–9, the names of positions 1,2,3 (as in Figs. 1–2) were saved (position 1 shows the clip; position 2 — the handle; position 3 — the set of hairs). In FIG. 3 to 5 show flat brushes; in FIG. 3rd horizontal execution of the working circuit; in FIG. 4th semicircular execution of the working circuit; in FIG. 5 - with a beveled execution of the working circuit, in FIG. 6 - a flat brush. In FIG. 7, 8 show round brushes. In FIG. 9 - flattened round brush.

The essence of the proposed method for changing the contour of the end part of the hair bundle of the art brush, which consists in rigidly fixing the hair bundle in the fastener, to change the contour of the end part of the hair bundle of the art brush, the rigid fastening of the hair bundle for the time of changing its shape of the end part of the hair set is excluded.

Implementation of the proposed method for changing the end of the hair bundle of an art brush is as follows.

As an element providing both a rigid fixation of the hair bundle and the exclusion of rigid fixation of the hair bundle, thermoplastic glue 5 is used (the amount of glue 5 is determined experimentally by the brush manufacturer). The glue at room temperature rigidly fixes the hair bundle 3 of the art brush; when melting the thermoplastic adhesive 5, the rigid attachment of the hair bundle 3 is eliminated. For example, a heat cabinet can be used to melt the adhesive (the heat cabinet is not shown in Fig. 1, 2) with the brush in position shown in FIG. 1, 2 (in order to exclude the loss of end set 3 from the cage). When the adhesive is in a liquid state, the user provides the desired changes in the contour of the end part of the hair bundle 3 of the art brush without using templates or with those (the template is not shown in the drawings). At the same time, safety precautions must be observed, since work is done with hot objects. For example, work should be done with thermal gloves. To exclude changes in the color of the hairs, deterioration in their quality, as well as the quality of the coating of the handle and clip, etc. the melting point of glue 6 should not be higher than 70-80 ° C (see sources of information:

http://globsite.narod.ru/derevo/klei/svoistva.htm Composition and basic properties of adhesives. Section adhesion adhesives.

http://art-con.ru/node/3731 Thermoplastic adhesives). Raising the temperature above 100 degrees Celsius is not permissible, since vaporization can occur in the wooden handle and, as a result, increase the pressure in the container and squeeze the hair bundle.

Moreover, the lower the melting temperature of thermoplastic adhesive 5, the safer it will be to work with it. After the desired change in the contour of the end part of the hair bundle of the artistic brush of the hair bundle 3, the adhesive 5 is cooled, the hair bundle 3 is rigidly fixed in the clip 1.

The hair bundle 3 is inserted into the clip unbound.

A specific change in the shape of the end of the brush after melting of the thermoplastic adhesive can be made, for example, as follows.

For example, in a round artistic brush (Fig. 7), by extending the central part of the hairs (by pulling out part of the hairs, for example with tweezers or fingers), a brush with a sharp extended tip is obtained - Fig. 8 - (such a brush is used to draw long thin lines without additional dipping the brush in the paint, since shorter hairs form an additional hair bundle, the hairs of which hold an additional amount of paint). The same conversion can be done with the flat brush of FIG. 4 (from a flat brush of FIG. 4, perform, for example, a flat brush of FIG. 6).

With a round art brush, you can change the hair styling and get a round brush with a flat outline of the hair bundle (this option is not shown in the drawing). Such a brush is necessary for blending pastels. Typically, such brushes are very difficult to find in the art salon due to the fact that they are little in demand by artists. Often, sellers do not even know about the existence of such brushes, for this reason they do not go on sale. Using this technical solution using hot melt adhesive allows you to get a change in the contour of the smear without leaving the workshop.

Reducing the size of a flat brush or reducing its filling by shifting part of the hairs inside the cage, you get a reversible opportunity to change the size of the brush (stroke width) or filling (stroke thickness). This embodiment of the brushes in the drawings is not displayed.

The molten glue allows you to change the shape of the clip at the place where the hair bundle exits from it, while when the glue hardens, it again reliably holds the hair in the clip with a changed shape of the smear. For example, can be obtained from the round brush of FIG. 7 flat brush having the shape of "Cat's tongue" (Fig. 9).

The final result of the proposed technical solution is to obtain the possibility of converting one type of smear contour into another, for example, from the smear contour of FIG. 1 to the smear circuit of FIG. 3, from the stroke of the smear of FIG. 3 to the smear circuit of FIG. 4, from the stroke of the smear of FIG. 4 into the smear circuit of FIG. 5 etc. with the possibility of their reverse transformation. In this case, it is necessary to bear in mind the practical impossibility of converting a flat brush into a round one without visible external defects.

Wider functionality with the introduction of creativity through independent changes in the characteristics of the artistic brush: changing the shape of the end set of the hair bundle is the advantage and advantage of the proposed technical solution compared to the prototype.

The production of the proposed brushes was mastered at the enterprise of the individual entrepreneur Byakov Andrei Leonidovich, Kirov, contact phone number 8 (8332) 21-16-04. The test of the experimental batch was held at the Imperial Porcelain Factory OJSC.
