Description

Technical Field

[0001] The invention relates to a violin bow positioner, which is installed on a bow of a violin, for example. Background Art

[0002] The bow (also called the bow) is an important part of the violin, for example, and it is closely related to the performance of the violin. Before learning the violin, beginners must first learn how to hold the bow well, and then they can learn to move the bow. Generally, the bow movement starts with the middle bow, because the movement of the forearm is easier than that of the upper arm. The middle bow is the movement of the forearm, and the coordinated movement of the wrist is easy to make and will develop more normally without any artificiality. Starting from the middle bow and then gradually stretching to both ends will allow students to play a wide sound. The lower half of the bow movement only uses the upper arm, and the muscles of the upper arm should actively move the bow back and forth, and should not be pulled by the forearm. Then fix the elbow joint, and only the forearm is used for the upper half of the bow. The upper arm and shoulder are completely relaxed, and the bow movement is performed with the elbow joint as the fixed point like a robot. In addition, different bowing methods should choose different bow sections. However, beginners cannot accurately divide the bow sections (bow positions), i.e., upper bow, middle bow, and lower bow, due to their lack of knowledge, which increases the difficulty of bow movement.

[0003] Bow segmentation usually refers to the division of the length of the entire bow, starting from the tip of the bow, into the upper bow, middle bow and lower bow. Generally speaking, the upper bow part of the bow is light and suitable for playing fast; the middle bow part of the bow is more elastic and can be used for special bowing techniques, such as jumping bows and throwing bows; the lower bow part of the bow is powerful and suitable for playing explosive and loud sounds, such as chords. Therefore, when beginners practice bowing, they should practice in sections. In order to make it easier for beginners to remember the position of each bow section, the current practice is to stick one or two white tapes on the bow rod to mark the upper bow, middle bow and lower bow. However, this will lead to the following problems: (1) When beginners draw the bow, the bow hair may slide over the strings and may accidentally exceed the position marked by the white tape, resulting in drawing the bow in the wrong position; (2) The white tape sticks to the bow stick, affecting the appearance of the bow stick. Furthermore, if the white tape is attached for a long time, once it is torn off, the sticky part of the white tape will easily stick to the bow stick, making it time-consuming and laborious to clean the bow stick. Summary of the invention

[0004] The present invention is made in view of the above problems, and an object of the present invention is to provide a violin bow positioner, which can ensure that beginners draw the bow in the correct bow position and quickly master the bow position.

[0005] According to the present invention, there is provided a violin bow positioner, which is elastic and configured to be fixed on a bow rod of a violin bow. The violin bow positioner comprises:

[0006] A cylindrical body, a through hole formed in the body and a first opening communicating with the through hole formed on an outer peripheral wall of the body;

[0007] a surrounding portion that surrounds the main body and is formed with a second opening; and

[0008] a hook portion, the hook portion protruding from the surrounding portion;

[0009] The bow rod is inserted into the through hole through the second opening and the first opening, and the bow hair of the bow is located inside the hook portion.

[0010] According to the above structure, since the bow rod of the violin bow is embedded in the through hole of the main body through the second opening and the first opening and the violin bow positioner is fixed on the bow rod, it is possible to use a violin bow positioner to reliably mark the upper half bow and the lower half bow on both sides thereof, or use two violin bow positioners to reliably mark the middle bow between the two. Therefore, it is possible to ensure that beginners can judge the correct bow position and quickly master the bow movement position. In addition, when the violin bow positioner is fixed to the bow rod, the bow hair of the violin bow is located inside the hook part, so that even if the beginner accidentally uses too much force, the hook part will not pass the violin bow positioner and move the bow at the wrong bow position due to the obstruction of the hook part, so it is possible to ensure that the beginner moves the bow at the correct bow position.

[0011] Preferably, according to the present invention, the violin bow positioner can be integrally formed by injection molding.

[0012] According to the above configuration, the violin bow positioner is integrally formed by injection molding, so the processing is convenient and the production efficiency is high.

[0013] Preferably, according to the present invention, the violin bow positioner can be made of silicone.

[0014] According to the above configuration, since the violin bow positioner can be made of silicone, the violin bow positioner has elasticity and is durable.

[0015] Preferably, according to the violin bow positioner of the present invention, the diameter of the through hole can be equal to or slightly smaller than the diameter of the bow rod.

[0016] According to the above structure, the bow rod can be reliably fixed in the through hole by the elasticity of the violin bow positioner.

[0017] Preferably, according to the violin bow positioner of the present invention, the opening size of the first opening can be smaller than the diameter of the bow stick.

[0018] According to the above structure, when the bow rod passes through the first opening, the first opening is squeezed outward and deformed to enlarge its opening size, thereby allowing the bow rod to pass therethrough, and after the bow rod passes through, the first opening returns to its opening size before deformation, thereby preventing the bow rod from escaping from the through hole. Therefore, the bow rod can be firmly fixed relative to the through hole. Thus, the violin bow positioner is firmly fixed on the bow rod of the violin bow.

[0019] Preferably, according to the violin bow positioner of the present invention, the opening size of the second opening can be smaller than the diameter of the bow stick.

[0020] Preferably, according to the present invention, the violin bow positioner may further include a rib provided between the main body and the surrounding portion.

[0021] According to the above configuration, the surrounding portion can be reliably supported by the rib, thereby enhancing the strength of the surrounding portion.

[0022] Preferably, according to the present invention, the violin bow positioner may further include a handle protruding from the surrounding portion at a side opposite to the hook portion.

[0023] With the above structure, when fixing the violin bow positioner to the bow rod of the violin bow, the user can grasp the handle to facilitate the above fixing.

[0024] Preferably, according to the present invention, the violin bow positioner can be formed in substantially the same shape as a treble clef.

[0025] With the above structure, the violin bow positioner is formed into a shape substantially the same as the treble clef, so the violin bow positioner has a beautiful appearance.

[0026] The above and other objects, features and advantages of the present invention will become more apparent from the following description in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is an explanation of the implementation of the present invention by means of specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0033] Now, exemplary embodiments of the present invention are described with reference to the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to disclose the present invention in detail and completely and to fully convey the scope of the present invention to those skilled in the art. The terms used in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, the same units / elements are marked with the same reference numerals.

[0034] Unless otherwise specified, the terms (including technical terms) used herein have the commonly understood meanings to those skilled in the art. In addition, it is understood that the terms defined in commonly used dictionaries should be understood to have the same meanings as those in the context of the relevant fields, and should not be understood as idealized or overly formal meanings.

[0035] Figure 1 1 is a perspective view showing a violin bow positioner 10 according to an embodiment of the present invention. Figure 2 1 is a side view showing a violin bow positioner 10 according to an embodiment of the present invention.

[0036] like Figure 1-2 As shown, the violin bow positioner 10 includes a handle 1, a hook portion 2, a columnar body 3 and a surrounding portion 4, and has a certain thickness. In this embodiment, the violin bow positioner 10 is integrally formed by injection molding and can be made of, for example, silicone. Further, the violin bow positioner 10 is formed into a shape substantially the same as a treble clef, such as Figure 2 shown.

[0037] As shown in the figure, a through hole 5 is formed in the main body 3, and the through hole 5 penetrates the main body 3 in the thickness direction. A first opening 6 communicating with the through hole 5 is formed on the peripheral wall 9 of the main body 3, and the first opening 6 is formed on the entire thickness of the peripheral wall 9. The surrounding portion 4 surrounds the main body 3 and is formed with a second opening 7, and the second opening 7 is formed on the entire thickness of the surrounding portion 4. The surrounding portion 4 is spaced a certain distance from the main body 3.

[0038] like Figure 2 As shown, the hook portion 2 protrudes from the surrounding portion 4 (e.g. Figure 2 ), and the handle 1 protrudes from the surrounding portion 4 on the side opposite to the hook portion 2 (e.g. Figure 2 upward protrusion).

[0039] The violin bow positioner 10 further includes a rib 8, which is provided between the body 3 and the surrounding portion 4. Further, the rib 8 plays a role in reinforcing the strength of the surrounding portion 4.

[0040] Further, the violin bow positioner 10 according to the present invention is basically constructed as described above. The following will describe a case where the violin bow positioner 10 is fixed to the bow rod 11 of a violin bow, for example.

[0041] The bow rod 11 is caulked into the through hole 5 through the second opening 7 formed on the surrounding portion 4 and the second opening 7 formed on the peripheral wall 9. More specifically, the opening sizes of the first opening 6 and the second opening 7 are both smaller than the diameter of the bow rod 11. Further, the diameter of the through hole 5 is equal to or slightly smaller than the diameter of the bow rod 11.

[0042] First, when the bow rod 11 passes through the second opening 7, since the violin bow positioner 10 is made of silicone and has elasticity, the surrounding part 4 is squeezed outward at the second opening 7 to enlarge its opening size, thereby allowing the bow rod 11 to pass through it. Then, similarly, when the bow rod 11 passes through the first opening 6, since the violin bow positioner 10 is made of silicone and has elasticity, the outer peripheral wall 9 of the main body 3 is squeezed outward at the first opening 6 to enlarge its opening size, thereby allowing the bow rod 11 to pass through it. As a result, the bow rod 11 enters the through hole 5 through the second opening 7 and the first opening 6, and thereafter the second opening 7 and the first opening 6 restore their opening sizes before deformation. When the bow rod 11 enters the through hole 5, the through hole 5 is squeezed outward, thereby the bow rod 11 is embedded in the through hole 5. In addition, while the bow rod 11 is embedded in the through hole 5, the bow hair 12 of the bow is placed inside the hook part 2. Since the first opening 6 and the second opening 7 return to the opening state before the deformation after the bow rod 11 is inserted into the through hole 5, the bow rod 11 is fixed relative to the through hole 5, and the restored first opening 6 can prevent the bow rod 11 from escaping from the through hole 5. Thus, in the above-mentioned fixing manner, the violin bow positioner 10 is firmly fixed on the bow rod 11 of the violin bow.

[0043] The application of the violin bow positioner 10 according to the present invention will be described below.

[0044] Figure 3 1 is a schematic diagram showing a violin bow positioner 10 being fixed on the bow rod 11 of the violin bow. Figure 3As shown, a violin bow positioner 10 is fixed at the approximate middle position of the bow rod 11 by the above-mentioned fixing method, thereby separating the violin bow into a segment A and a segment B, wherein segment A corresponds to the upper half of the bow, and segment B corresponds to the lower half of the bow. Thus, a beginner can use the upper half of the bow and the lower half of the bow to move the bow on both sides of the violin bow positioner 10. In addition, since the bow hair 12 is located in the hook part 2 of the violin bow positioner 10 at this time, the bow hair 12 is also divided into two left and right parts by the hook part 2. Thus, for example, when a beginner moves the upper half of the bow (or the lower half of the bow), even if he accidentally uses too much force, the bow hair will not pass through the violin bow positioner 10 and move to the lower half of the bow (or the upper half of the bow) due to the obstruction of the hook part 2 of the violin bow positioner 10. Therefore, it can be ensured that the beginner moves the bow in the correct bow position and the beginner can quickly master the bow movement position (upper half of the bow and lower half of the bow).

[0045] Figure 4 1 is a schematic diagram showing two violin bow positioners 10 being fixed on the bow rod 11 of the violin bow. Figure 4 As shown, the two violin bow positioners 10 are fixed at two positions of the bow rod 11 by the above-mentioned fixing method, thereby defining a segment C between the two violin bow positioners 10, and the segment C corresponds to the middle bow. Therefore, beginners can use the middle bow to move the bow between the two violin bow positioners 10. In addition, since the bow hair 12 is located in the hook parts 2 of the two violin bow positioners 10 at this time, when beginners move the middle bow, even if they accidentally use too much force, due to the obstruction of the hook parts 2 of the two violin bow positioners 10, they will not move from the middle bow over the violin bow positioners 10 to other bow positions. Therefore, it can be ensured that beginners move the bow at the correct bow position and beginners can quickly master the bow position (middle bow).

[0046] Furthermore, it should be noted that although Figure 3 and 4 The bow stick 11 and bow hair 12 of the bow in the figure are shown as being substantially straight lines, however this is merely schematic, and the bow stick and bow hair of the actual bow may be curved.

[0047] The effects of the violin bow positioner according to the present invention will be described below.

[0048] (1) In this embodiment, since the bow rod 11 of the violin bow is inserted into the through hole 5 of the main body 3 through the second opening 7 and the first opening 6 and the violin bow positioner 10 is fixed to the bow rod 11, the upper and lower bow halves can be reliably marked on both sides of the violin bow positioner 10, such as Figure 3 As shown, or by using two violin bow positioners 10, the middle bow can be reliably marked between the two, such as Figure 4As shown. Therefore, it can ensure that beginners can judge the correct bow position and quickly master the bow position. In addition, when the violin bow positioner 10 is fixed to the bow rod 11, the bow hair 12 of the violin bow is located inside the hook part 2, so that even if the beginner accidentally uses too much force, the hook part 2 will not block the violin bow positioner and move the bow in the wrong bow position. Therefore, it can ensure that the beginner moves the bow in the correct bow position.

[0049] (2) In this embodiment, the violin bow positioner 10 is integrally formed by injection molding, so it is easy to process. In addition, four violin bow positioners can be injection molded at the same time in the same mold, so the production efficiency is high.

[0050] (3) In this embodiment, when the bow rod 11 passes through the first opening 6, the first opening 6 is squeezed outward and deformed to increase its opening size, thereby allowing the bow rod 11 to pass through it and enter the through hole, and then it returns to its opening size before deformation, thereby preventing the bow rod 11 from escaping from the through hole 5. Therefore, the bow rod 11 can be firmly fixed relative to the through hole 5. Thus, the violin bow positioner 10 is firmly fixed on the bow rod 11 of the violin bow.

[0051] The above briefly describes the preferred embodiment according to the present invention. The following will describe the variation according to the present invention.

[0052] In the above embodiment, the violin bow positioner is integrally formed by injection molding. However, the present invention is not limited thereto. The violin bow positioner can be formed by combining multiple parts.

[0053] In the above embodiment, the violin bow positioner is made of silica gel. However, the present invention is not limited thereto. The violin bow positioner can be made of other elastic materials, such as rubber.

[0054] In the above embodiment, the surrounding portion is spaced a certain distance from the main body and a rib is disposed therebetween. However, the present invention is not limited thereto, and the surrounding portion and the main body may be formed continuously without a rib disposed therebetween.

[0055] In the above embodiments, one or two violin bow positioners are fixed on the bow rod. However, the present invention is not limited to this. Any number of violin bow positioners can be provided as required.
