Abstract

PROBLEM TO BE SOLVED: To provide a shoulder rest of a violin which can stably support a violin, reduces the risk of joint pain and the like, and does not cause noise generation due to resonance of a support portion or the like. SOLUTION: In order to prevent the violin from falling off and to prevent stiff shoulders, shoulder joint pain or cervical spondylosis, the load moment of the violin is supported by a shoulder cushion portion 16 that softly contacts the bottom surface of the shoulder rest with the periphery of the shoulder and a steeply inclined surface of the chest. The non-slip net portion 17 is configured to disperse the violin load from the shoulder cushion portion 16 to the non-slip net portion 17 that is supported by the steeply inclined surface of the chest, and supports the body without restraining the body during the performance. [Selection diagram] Fig. 1

Description

In light of vibrato and other advanced performance techniques, it is important to hold the violin up and down from the clavicle without touching the shoulder joint. The structure that supports the violin load moment on the steep slope of the chest while supporting with the gently inclined surface of the pectoral clavicle is unresolved, and the technology to prevent muscle pain around the shoulder joint, tenosynovitis, cervical spine pain, etc. Furthermore, the elimination of the acoustic noise generated from the shoulder rest that inhibits the sound of the violin is unsolved, and the above solution is the technical field of the invention.

The violin body was completed in the 1600s by Italian Amati, and many musicians were fascinated by the rich sound of violin masterpieces. Violins with rich acoustics can no longer be produced, while the violin chin rest was invented in the 1800s by Louis Sporer and the violin shoulder rest was invented in the 20th century by menu-in. FIG. 2 shows a state where the chin rest and shoulder rest are attached to the violin. Each improvement continued and contributed to the improvement of violin performance technology, and the violin chin rest became popular enough to be used by most performers, but the shoulder rest was due to dissatisfaction such as generating structure and acoustic noise that are difficult to weaken, In view of the situation where there are many people who fold a special material fabric and wrap it from the chin rest to the shoulder instead of using the shoulder rest, the present invention is a technical field where the completion of the shoulder rest is desired.

Assignment 1

The conventional shoulder rest of the kind that connects a pair of hooks that hold the violin back plate from the left and right with a certain gap between the pair of hooks is supported by a simple flat bottom shape from the clavicle. Because the terminal of the shoulder pad on the human body side makes unstable contact with the chest on the steeply inclined surface of the chest, the conventional shoulder pad (distance from the contact point of the shoulder pad to the human body to the jaw) is shortened, and the violin In the load moment formula (violin load moment) = (distance from the contact point of the shoulder pad to the human body)
× (Because it supports the violin acting on the jaw)
Conventional shoulder pads (the ability to support the violin acting on the chin) are likely to cause stiff shoulders and shoulder joint pain, cervical pain due to excessive pressing of the simple bottom surface with the chin, In view of the situation where the violin is easy to slide down and it is difficult to weaken during performance, the present invention softly supports the clavicle from the clavicle with the shoulder cushion part, and from the clavicle to the inclined surface of the clavicle clavicle. In contrast, it forms a shoulder pad bottom that can be bent and twisted, even on steeply inclined surfaces of the chest, increasing the distance from the contact point of the shoulder pad to the chin and supporting the violin acting on the chin. The challenge is to reduce the force.

Issue 2

The conventional shoulder pad has a structure in which the hook of the violin sandwiches the edge of the violin back plate and a gap between the edges, and the structure is easy to fall off without grasping the edge firmly, and the conventional hook is the violin back plate There is no measure to prevent the dropout other than pressing it against the edge of the wrist, and if the shoulder rest is slightly shaken during the performance, it will loosen easily and fall off easily, especially to prevent shoulder stiffness, joint pain and cervical vertebra pain etc. In order to support the clavicle from the clavicle to the center of the clavicle without touching the shoulder, the position of gripping the edge of the violin back plate by shortening the interval between the left and right hooks is brought close to the neck. In view of the situation that it is close to the end pin and is more easily removed by the conventional shoulder pad, according to the present invention, a gripping mechanism for gripping the edge of the violin back plate to the hook and a mechanism for pressing the hook to the edge of the violin back plate And hook Tsu also click is off is it is a problem to arrange a mechanism to prevent the fall of the shoulder rest.

Issue 3

The conventional shoulder rest is a structure that receives a violin load from the clavicle to the greater pectoral clavicle, and in view of the structure that receives almost no load on the steeply inclined surface of the chest, according to the present invention, the brackets on both ends and the shoulder rest body An autonomous rotation mechanism that autonomously adjusts the inclination angle is arranged, and when the tip of the shoulder pad bottom surface touches the steeply inclined surface of the chest, it autonomously continues until the bottom surface of the shoulder pad closely contacts the steeply inclined surface of the chest The challenge is to make a mechanism that rotates and receives the violin load moment from the clavicle at the clavicle part of the greater pectoral muscle without touching the shoulder joint and at the steeply inclined surface of the chest.

Exercise 4

Conventional shoulder rests are often used as shoulder rests that increase the acoustic vibrations by mixing the vibrations of the shoulder rests with the violin sound, or the shoulder rests that generate acoustic noises unintentionally. In view of the situation where there are many performers who do not use the shoulder rest and obstruct the sound, the present invention makes it possible to produce a sound plate for the violin sound conducted to the shoulder rest and a strong shoulder rest outer shell (elongated box shape). A strong outer shell that forms the outer wall surface of the shoulder rest beam facing the arm of the triangular column-shaped portion and the arm, and a strong outer shell that forms the rectangular end surface and the neck-side outer wall surface of the elongated box-shaped portion, and the triangular prism-shaped portion It is a problem to make a steep bottom surface and a strong outer shell constituting the triangular end surface of the material with no acoustic noise.

Exercise 5

Unlike conventional shoulder pads, chin rests are made of a plastic or plastic material of the same quality.Therefore, the shoulder rests of the present invention require less force to push the chin rests, and can be used as a side effect. Since the violin is likely to slide down due to the sweat and fat, it is a problem to provide a simple attachment / detachment mechanism while covering the chin rest with a non-slip material.
