[Industrial applications]

 TECHNICAL FIELD The present invention relates to a brush, especially a paintbrush for painting, which is suitable for use by people who specialize in design or illustration.

[0002]

[Prior art]

 In today's colorful product society, designs and illustrations added to products have become more flashy with more colors. For this reason, many designers and illustrators who produce such products use a large number of brushes for painting designs, depending on the color to be used or the thickness of the line to be drawn. In need. Generally, such brushes are classified into thin, medium, thick, etc. according to the size of their tips, and the user may choose his / her own, depending on his / her work content, how well the brush is grasped, or the weight of the brush. The most suitable one is selected and used.

However, in many of the brushes for painting patterns currently in use, the tip, the metal fitting for fixing the tip and the shaft to which the metal fitting is attached are integrally assembled in a non-removable manner. There is. Therefore, designers have to prepare their own brushes depending on the thickness of the line to be drawn or the type of color to be colored, and as a result, dozens of brushes must be prepared. As a result, the designer's desk or workbench was filled with long paintbrushes, and even the original work was difficult.

In order to eliminate such inconvenience, the same applicant previously announced a brush in which only the shaft portion of the paint brush can be shared. In many cases, lines with the same color and thickness in a given design or illustration are often finished with the same brush at one time. It is rare to use it again. Therefore, by replacing the brush part that was used once with the brush part that will be used next, there is no possibility that the original workability of the designer will be affected, and the shaft part can be shared as described above. As a result, at least the part of the shaft that composes most of the length of the brush can be limited to the minimum number, and as a result, the area occupied by the brush to be placed on the workbench is halved. I did.

[0005]

[Problems to be solved by the device]

 The above proposal makes a great contribution to designers and others. However, the weight of the paintbrush, especially the subtle changes in the center of gravity of the paintbrush, have a great impact on the creative work of the designer. That is, in general, even with the same brush, it is preferable that the position of the center of gravity of the paintbrush is in the lower part of the brush when performing a detailed and delicate description, and conversely, when performing a rough description to some extent. It is preferable in terms of workability that the center of gravity of is located above the brush. For this reason, designers and the like sometimes work while adjusting the center of gravity by attaching a rubber band or the like to the upper end of the brush in some cases and to the lower end of the brush in other cases.

This is because, until now, it has not been announced that the center of gravity of the brush can be freely adjusted in one brush or in the common axis as described above. Therefore, the present invention provides a paintbrush for a pictorial design whose center of gravity is adjustable.

[0007]

[Means for Solving the Problems]

 A grip that is slidable up and down is provided on the shaft portion of the brush, and screw means that can stop the grip at least at two upper and lower positions is provided.

[0008]

[Action]

 The user can easily move the brush's center of gravity position by freely moving the grip up and down according to the coloring work, so that the center of gravity of the brush to be used is always at the optimum position. So that the desired coloring work can be performed.

[0009]

It comprises a shaft 4 and a grip 5 movable along the shaft 4. FIG. 1 shows a state in which the grip 5 is on the tip side (hereinafter, referred to as lower side), while FIG. 2 shows a state in which the grip 5 is at a position apart from the tip side (hereinafter, referred to as upper side).

The tip fitting 3 is made of brass or another metal member, and converges toward the tip of the tip 2 in a tapered shape, and the tip 2 of the tip fixing portion 10. And a tip shaft fixing portion 12 which has a substantially same diameter and extends in a direction opposite to. Furthermore, as shown in FIGS. 3 and 4, the tip shaft fixing portion 12 of the tip fitting 3 is provided with a hole 14 extending toward the tip fixing portion 10, and the hole 14 is provided in the hole 14. Threads with a certain pitch are threaded.

The shaft 4 is preferably likewise constructed of a metallic material. The shaft 4 is preferably formed by a lower end member 20, an intermediate member 22, and an upper end member 24, as shown in FIGS.

The lower end member 20 has substantially the same diameter throughout. A screw 26 that is screwed into the threaded hole 14 of the tip fitting 3 is provided at one end thereof. On the other hand, the other end has a hole 28 for receiving and fixing one end of the intermediate member 22.

The intermediate member 22 has a central portion 30 having a diameter smaller than the diameter of the lower end member 20 and reduced diameters at both left and right ends of the intermediate member 22 which are smaller than the central portion 30. And parts 32 and 34. Further, screws 36 and 38 having a predetermined pitch are cut at both ends of the central portion 30. The directions of the screws may be the same or opposite to each other. One reduced diameter end 32 is received in and affixed to the hole 28 in the lower end 20. Means for fixing may be splicing, adhesive or other known means.

The upper end member 24 has a larger diameter than the diameter of the central portion 30 of the intermediate member 22, and preferably has a diameter substantially the same as the diameter of the lower end member 20. Further, a hole 40 for receiving and fixing the other reduced diameter end portion 34 of the intermediate member 22 is provided at one end thereof. Means for fixing may be screwing, adhesive or other known means. A small hole 42 is likewise provided at the opposite end thereof, and a crown 44, which is preferably integrally molded of resin, is removably fitted therein. The tail cap 44 is made of, for example, a resin mixed with various pigments for identifying the color of the brush being used, so that the tail cap 44 having a color corresponding to the color of the brush being used can be attached. I am doing it. Alternatively, it is possible to form a groove 46 in the crown 44 and to mix the groove 46 with a color that can identify the color in use.

The grip 5 is preferably made of the same material as that of the shaft 4, and is formed of a hollow member having a hole 48 penetrating in the longitudinal direction. The grip 5 has a length of about the sum of the lower end member 20 and the intermediate member 22 of the shaft 4, and the inner diameter of the hollow member is about the lower end member 20 and the upper end member 24. Has a size slightly larger than the outer diameter of the member and slides on the surface of those members 20, 24. An inner screw 50 that is screwed into screws 36 and 38 provided on both sides of the central portion 30 of the intermediate member 22 is provided at a substantially central portion of the hole 48.
