    15 20 25 30 2 furthermore an angle-adjustable extension shaft for paintbrushes. The angle adjustment is possible through the elbow element or the joint located in the shaft.
    US7178191 discloses a paintbrush having an angle-adjustable and removable handle, which is provided by the brush having a U-shaped component along which the handle can be passed. US2002 / 0066151 A1 further describes a paintbrush having an angle-adjustable handle, which is made possible by the handle comprising a flexible part. The flexible part can be bent and in this way the angle of the handle relative to the brush can be adjusted. US2004 / 187266 A1 describes a paintbrush with a pivotable handle. This is achieved by fixing the handle in the brush part with a pivotable element, such as different types of screws.
    The object of the present invention is to provide a paintbrush which significantly facilitates painters who want to paint in places which are difficult to reach, both in terms of their built-in function and in terms of stability and simplicity of use. Furthermore, an object of the present invention is to provide a paintbrush as above which is relatively inexpensive to manufacture and does not require additional advanced components to achieve the intended effect in use.
    SUMMARY OF THE INVENTION The objects of the present invention are achieved by means of a one-piece ergonomic paintbrush comprising a main body comprising tin and brush bristles, which brush bristles extend substantially in a longitudinal direction of the main body, the paintbrush further comprising a non-rotatable and non-rotatable handle having a free end with a free handle center endpoint and having a closed end, where the non-rotatable and non-removable handle meets the plate, having a closed handle center end point and the main body having a transverse geometric axis perpendicular towards the longitudinal direction of the main part and which transverse geometric axis intersects through the closed handle center end point, a geometric line extending from the free handle center end point to the closed handle center end point forming an angle with the transverse geometric axis. in the same plane as in the interval t of 35-55 degrees.
    The ergonomic paintbrush of the present invention has several advantages. Since the handle is angled in the same plane as the main part, the paintbrush can be used for surfaces to be painted where the painter cannot easily and comfortably hold a handle or extension shaft perpendicular to the surface to be painted. In addition, the paintbrush according to the present invention is easy to use and gives a good result when used due to the stability present in the construction. The paintbrush according to the present invention is in one piece, which means that there are no parts, such as angle adjusters or extra handles, that must be connected for the brush to be used with the intended function.
    The brush according to the present invention can be connected to an extension shaft so that the brush can be used when, for example, high-lying surfaces are to be painted, such as attic rails, but the brush itself is made in one piece where the handle is fixed and can neither be removed nor twists. This fixed solution of the handle provides a stable function that increases the result when it is used.
    Furthermore, the paintbrush is inexpensive to produce when compared with the solutions available today, some of which are discussed above and below. As the handle consists of an angled profile, this can be manufactured in the same way as other profiles of eg plastic. This means that, for example, injection molding or extrusion can be used to manufacture the handle for the paintbrush according to the present invention.
    In comparison with currently known paintbrushes, the present invention has several advantages, which derive from differences between the present paintbrush and these known brushes. When compared to the type of paintbrush described according to US2009 / 0165233 A1, that brush is not intended to solve the same type of problem as the present invention. The brush according to US2009 / 0165233 A1 is designed to be suitable and effective to hold in the hand when used. Therefore, the handle is also angled downwards, left or right edge and twisted. On the other hand, the handle does not have an angle in the same plane as the brush part, which is the basis according to the present invention. A similar solution to US2009 / 0165233 A1 is described in US6742213. Another type of known paintbrush having a specially designed handle is that described in US4495669. This paintbrush has double handles. Also in this case, the paintbrush has a different type of design and it is clear, among other things, that the extra handle does not have a closed end where the handle meets the sheet metal and that it also does not form an angle in the plane as according to the present invention.
    In addition to the above known brushes, there are also other known devices that may be of interest to illuminate in this context. Among other things, a paintbrush holder according to US5329663, which is intended to enable a painter to be able to paint places that are difficult to reach and where the angle of the brush may need to be changed. The disadvantages of this construction are several.
    Firstly, this device means that this additional device must be brought when the places according to the above are to be painted. Secondly, the device is relatively complicated and therefore expensive to produce and purchase. Thirdly, and most importantly, a device such as this means that stability is reduced in risk when painting work is to be carried out. This holder becomes a sub-component between the brush and the extension shaft, which risks causing instability to the entire composite structure. This makes the painting work difficult to perform with high precision.
    Another type of solution is described in US3668731, where a brush holder is shown which can be connected to a brush handle. The brush holder is helical and can be connected to an extension shaft. Even in this case, the solution is complicated and causes problems regarding extra equipment that is needed, that the brush holder will not work for different designs of brushes and also that the extension shaft must be adapted to this particular brush holder. A similar but different solution is described in US4157598, where the same type of problems as described above are also valid. In addition, paintbrushes should be considered as consumables as the brushes deteriorate over time after some use. This is not something that the solution according to US4157598 takes into account. Likewise, the angle-adjustable extension shaft described in US3737187 is complicated and is thus a relatively expensive solution. Other complicated and relatively expensive solutions are sometimes described, inter alia, in US7178191, in which document a paintbrush having an angle-adjustable and detachable handle is described. The paintbrush has a U-shaped component along which the handle can be moved, which can thus be adjusted angularly.
    This solution is of course complicated and there is also a great risk that stability will be hampered. In addition, this solution also does not support the fact that paintbrushes should be considered as consumables. The problems described above are also valid for the paintbrushes described in US2002 / 0066151 A1 and US2004 / 187266 A1, which brushes are also complicated and entail a risk of instability and thus impaired painting work. In addition, for example, a paintbrush according to US2004 / 187266 A1 causes the problem that the fastening element 40, which is some form of screw, risks ceasing to function when paint ends up on this part. When this happens, the paintbrush will lose its rotation function. In general, solutions that have some form of rotation to be able to function, such as by torque in the form of threads, screws or where the extension rod is to provide this effect, present problems in use. This is because after a certain period of painting, these torques will be full of paint and thus wedge through adhesive effect from adhesive components in the paint.
    In relation to the known devices described above, the present invention has several advantages. Firstly, the device according to the present invention provides a stability in use which means that good precision can be achieved when painting. When the paintbrush is in one piece and where the handle is both non-rotatable and non-removable, a charter is achieved which is important when painting work is to be performed. By "one piece" is meant in this case that the paintbrush has no detachable parts after it has been manufactured. On the other hand, it is of course obvious that the paintbrush is manufactured by joining different parts together, such as handles, tin and brush wire part.
    Secondly, the present paintbrush means that fl your components, in addition to of course an extension shaft when needed, must not be used when special painting work is to be carried out on surfaces that are difficult to reach. This also means that good stability can be achieved because no intermediate sub-components are needed between the brush and the extension shaft. 10 15 20 25 30 6 Third, the paintbrush is inexpensive and easy to manufacture as common techniques, such as injection molding or extrusion, can be used to make the handle part.
    The angle that exists between the geometric line extending from the free handle center endpoint to the closed handle center endpoint and the transverse geometric axis is thus an angle that is in the same plane as the main body itself. It is important to realize that the angle can be mirror-inverted and can thus, for example, be mirror-inverted in relation to the angle shown in Fig. 1 which is explained below. Furthermore, it is important to realize that even if there is an angle in the same plane that is in the range of 35-55 degrees, the handle does not have to be extended in exactly the same plane as the main part. This means that in addition to being angled in the same plane as the main part, the handle can also be directed downwards or upwards in relation to the plane of the main part. In such a case, the handle thus also has an angle in relation to the plane of the main part. Furthermore, it will be appreciated that the geometric line described means that the handle may also be slightly curved even if a substantially straight extended handle is preferred. This in itself of course depends a lot on the appearance of an extension shaft if such is to be inserted into the handle.
    That the angle in the same plane should be in the range 35-55 degrees is a prerequisite according to the present invention. At angles outside this range, a brush to be connected to an extension shaft would not be as useful. This type of use, i.e. when the paintbrush is to be used together with an extension shaft, is the main area of use for a paintbrush according to the present invention.
    Brief Description of the Figure Fig. 1 illustrates a paintbrush according to the present invention.
    Detailed Description of the Invention Various specific embodiments of the present invention are described below.
    According to such an embodiment, a hanger for a bucket is arranged projecting from the non-rotatable and non-detachable handle. This hanger may, for example, be arranged as shown in Fig. 1, but may of course have a different location. This in itself depends on what is suitable for the user of the brush.
    According to a specific embodiment of the present invention, the geometric line is substantially completely in the same plane as the transverse geometric axis and the longitudinal direction of the main body. As can be seen from the above, this specific embodiment means that the handle is not substantially angled downwards or upwards from the plane.
    According to another specific embodiment, the angle in the same plane as the main part is in the range of 38-52 degrees. According to another specific embodiment, that angle is in the range of 43-47 degrees, such as about 45 degrees.
    According to a specific embodiment of the present invention, the non-rotatable and non-detachable handle is hollow from the free end towards the closed end for attaching an extension shaft to the non-rotatable and non-detachable handle. As can be seen above, the paintbrush of the present invention finds the best use when painting surfaces that are difficult to reach. An example of such surfaces are wind rails. It is also when such surfaces projecting straight out that the angle of the present invention is so important. In addition, paint brushes are needed which have good stability, which further demonstrates the advantages of the paint brush according to the present invention. Other terms for extension shafts that mean the same thing in this context are, for example, rod handles or extension rods.
    According to another specific embodiment of the present invention, the closed handle center end point is located in the middle or substantially in the middle of the main part where the non-rotatable and non-removable handle meets the plate. This embodiment means that the handle is placed in the middle of the paintbrush, as shown in Fig. 1 and which is preferred, but is not in itself a must according to the present invention.
    According to another specific embodiment of the present invention, the non-rotatable and non-detachable handle is straight or substantially straight and the geometric line constitutes or thus constitutes a geometric line within the non-rotatable and non-detachable handle. This has been explained above and thus means that the handle is not bent. Of course, the handle may be designed in different ways and not be exactly symmetrical, but it is preferred that the handle is not bent to any great extent. On the other hand, for example, the handle may very well have a slightly conical shape, which means that it is slightly thicker at the free handle center end point and tapers inwards along the handle. This can, for example, be of particular interest for an extension shaft to be able to be connected to a hollow handle in a safe and stable manner.
    The different parts of the paintbrush preferably include materials that are standard today for brushes. For example, the handle may preferably be of some form of plastic material and this part may, for example, be made by injection molding or extrusion.
    Detailed description of the figure In Fig. 1 an ergonomic paintbrush 1 is shown in one piece. The paintbrush 1 comprises a main part 2 which comprises plate 3 and brush brush 4. The brush brush 4 extends substantially in a longitudinal direction of the main part 2, which means that they extend from the plate 3 and out towards the free end of the main part 2 or the brush part. Furthermore, the paintbrush 1 comprises a non-rotatable and non-removable handle 5, which handle 5 has a free end 6 with a free handle center end point 7. The handle 5 is in this case directed to the left according to Fig. 1, but can also be mirror-inverted so that it is directed to the right, regardless of what is the top or bottom of the paintbrush 1.
    Furthermore, the handle 5 has a closed end 8 where the non-rotatable and non-removable handle 5 meets the plate 3. The closed end 8 of the handle 5 has a closed handle center end point 9. This closed handle center end point 9 normally has as shown in Fig. 1 a position which is in the middle of the paintbrush 1 or in the middle of the tin 3 along the geometric axis 10, but this means that the handle 1 also has a closed end 8 which faces the center of the paintbrush 1. The handle 1 may, however, have a position which is to the left or right of the center of the tin 3 and then the closed handle center end point 9 thus also has a position to the left or right of the center of the tin 3.
    Furthermore, the main part 2 has a transverse geometric axis 10 which is perpendicular to the longitudinal direction of the main part 2, and which transverse geometric axis 10 intersects through the closed handle center end point 9. A geometric line 11 extending from the free handle 10 The center endpoint 7 to the closed handle center endpoint 9 forms an angle 12 with the transverse geometric axis 10 in the same plane which is in the range of 20-70 degrees. As explained above, the handle 1 can be directed in the other direction than as shown in Fig. 1 and this means that the angle 12 is mirror-inverted to what is shown in Fig. 1.
    Furthermore, a hanger 13 for a bucket is arranged projecting from the non-rotatable handle 5 according to Fig. 1. This hanger 13 is thus intended for holding a paint bucket, for example.
    According to Fig. 1, the non-rotatable and non-detachable handle 5 is straight or substantially straight and the geometric line 11 thus forms or substantially constitutes a geometric line inside the non-rotatable and non-detachable handle 5. In addition, the handle 5 can of course be hollow to be able to be connected to an extension shaft. Furthermore, the handle can be slightly conical so that it tapers inwards so that an extension shaft can be wedged in firmly. Furthermore, the handle 5 does not have to be straight but can be slightly curved, which in that case would be due to the fact that, for example, an extension shaft to be used also has such a curved shape. Even in this case, however, a geometric line 11 and an angle 12 can be defined in the same way as above and under the same conditions, even if all of the geometric line 11 does not necessarily have to lie inside the handle 5.
