AI Technical Summary
The grip of existing brushes is not suitable enough when executing precision lines or repeating lines, making it difficult to provide multiple positions and precision.
A brush holder fitting consisting of a cylindrical tubular body and telescopic tubular arm is designed to hold the brush through a threaded head and allow stable retention in multiple positions, combining a rounded extension and a curved concave recess to enhance grip stability.
The versatility and accuracy of the brush in a variety of drawing technologies is achieved, and the brush is maintained by wrist movement instead of or combined with finger movement, improving the painting accuracy and flexibility.

Abstract
Description
Technical Field
[0001] The present invention relates to a brush holder accessory that allows a brush to be held in multiple positions, thus providing the possibility of maximum precision in brush applications using different techniques. Background Art
[0002] The brush has an elongated body designed to be held using three fingers by the head carrying the bristles, and the body rests against an arch formed by the thumb and index finger near its rear end.
[0003] However, when performing certain lines, such as precision lines or lines that require repetition or parallelism, this type of grip may not be the most suitable. Summary of the Invention
[0004] The brush holder accessory proposed by the present invention completely solves the aforementioned problems, providing a large number of possible positions for using the brush, as well as adjustable features that further increase its versatility.
[0005] Specifically, the device of the present invention consists of a cylindrical tubular body into which the brush is to be inserted, and the opening of the tubular body is associated with a threaded head or another mating system that clamps the brush against the tubular body, stabilizes the brush and allows it to be mounted in different relative positions according to the degree to which the brush is inserted into the tubular body, and also makes the brush replaceable.
[0006] Subsequently, the cylindrical tubular body is telescopically connected to a tubular arm equipped with a threaded head or another mating system that allows adjustment of the extension or retraction between the two telescoping elements. This configuration is one possibility, and another possibility is that the brush body is directly fitted into the handle, or even into a telescoping system having more than two tubular elements, where these elements are firmly fixed.
[0007] The arm terminates in a circular or curved expansion that defines a peripheral gripping surface allowing it to be held by the index finger of the user. The expansion also includes a curved concave recess on its upper surface, providing an alternative gripping portion for support, as well as support on the palm or on an arch formed by the thumb and index finger.
[0008] Therefore, using this structure, the device can be held in various ways by its head or interchangeable head and according to the position of the finger on the circular expansion, which allows the application of various drawing techniques using the brush, imparting a versatility that did not exist before. Brief Description of the Drawings
[0009] To supplement the description that will follow and to help better understand the characteristics of the present invention, a set of drawings is included as part of this description, according to preferred examples of its actual implementation. For illustrative rather than restrictive purposes, the following is shown:
[0010] · Figure 1 : A top perspective view showing a brush holder fitting made according to the purposes of the present invention.
[0011] · Figure 2 : Showing Figure 1 The outline of the device in
[0012] · Figure 3 、 Figure 4 And Figure 5 : Different perspective views showing several possible ways of using the hand-holding device according to the technique or preference for a specific type of stroke. Detailed Description of the Invention
[0013] As can be seen from the drawings, the brush holder fitting of the present invention consists of a cylindrical tubular body (3), and the cylindrical tubular body (3) will have an inner diameter corresponding to the outer diameter of the brush body (2) intended to be carried by the device. The brush is inserted into it from its front end to a desired depth, and in order to fix the brush, the cylindrical tubular body (3) includes a threaded head (1) at its front end, and the threaded head (1) clamps the brush against the tubular body. Once the threaded head is tightened, the brush is stably held in place.
[0014] Of course, by loosening the threaded head (1), the device will allow the use of brushes (2) with different bristle thicknesses, which can be selectively inserted into the cylindrical tubular body (3) according to the specific needs of each case.
[0015] According to another feature of the present invention, the cylindrical tubular body (3) fits axially into a tubular arm (4), giving the device telescopic characteristics. The tubular arm (4) includes a positioning screw or another fitting system (5) to stabilize the cylindrical tubular body (3)-tubular arm (4) assembly at a desired length according to the size of the user's hand.
[0016] The tubular arm (4) also terminates in a rounded extension (6), as seen in Figure 3 , which allows the device to rest stably against the arch formed by the thumb and index finger, or alternatively, according to the stroke technique to be used, the index finger can be placed peripherally around the extension while using the thumb and middle finger to hold the threaded head (1), as shown in Figure 4 .
[0017] Finally, the rounded extension (6) includes one or more curved concave recesses (7) on its upper surface, which create a thumb rest, as in Figure 5As shown. This allows the device to remain in the position shown in this figure, where the precision of the stroke depends on wrist movement rather than finger movement, as is conventional.
[0018] In short, the device allows precision in the stroke to depend not only on finger movement but also to be combined with or replaced by wrist movement, thus significantly increasing the versatility and customization of the device when applying different drawing techniques.
