Description

Technical Field

[0001] This application relates to the field of protective shoulder pads, and more particularly to a violin shoulder pad with adjustable height and angle. Background Technology

[0002] Violinists often experience shoulder and neck fatigue, muscle tension, and even chronic injuries due to improper posture during practice or performance. While traditional shoulder pads can alleviate some pressure, their fixed height and angle make it difficult to adapt to the physiological differences and performance needs of different players.

[0003] The existing Chinese utility model patent with publication number CN215577642U discloses an adjustable protective shoulder pad for violinists; however, it still has the following shortcomings in practical use:

[0004] 1. The comparative document utilizes the inertia of the second spring to firmly fix the limiting post inside the limiting groove, which facilitates the staff to adjust the height of the shoulder pad. The limiting post can only move up and down inside the limiting groove and cannot rotate. This means that during the adjustment process, both ends of the shoulder pad need to be adjusted at the same time, and both ends of the shoulder pad can only maintain the same height. It is not possible to adjust the height of one side of the shoulder pad and the overall angle separately. The fixed angle design cannot adapt to the differences in different playing styles and the shoulder sizes of different performers.

[0005] 2. During violin playing, the shoulder pad is located on the shoulder and is mainly used to support the violin body. However, the design in this comparative document sets the height adjustment direction of the shoulder pad to be consistent with the support direction of the violin body. When the hand applies force (such as pressing the string or bowing), the support stability of the shoulder pad decreases. During the performance, the height of the shoulder pad is easily changed or displaced due to vibration or force, which in turn affects the comfort and expressiveness of the performance. Utility Model Content

[0006] To address the issues of shoulder pads not being able to be adjusted independently and their lack of stability, this application provides a violin shoulder pad with adjustable height and angle.

[0007] This application provides a violin shoulder pad with adjustable height and angle, employing the following technical solution:

[0008] An adjustable violin shoulder pad includes a shoulder support pad, with a main rotating shaft rotatably connected to both ends of the shoulder support pad. An anti-slip pad is provided between the surface of the main rotating shaft and the surface of the shoulder support pad. An adjustment component for adjusting the height and angle of the shoulder support pad is provided outside the main rotating shaft. A support foot is provided outside the adjustment component. A fixing plate is fixedly connected to the outer side of the shoulder support pad away from the anti-slip pad.

[0009] By adopting the above technical solution, the adjustment component allows the performer to adjust the height of one side and the overall angle individually according to their own needs, and the shoulder support pad can remain stable in a vibrating environment during performance.

[0010] Preferably, the adjustment assembly includes a support column fixedly connected to the surface of the main rotating shaft, an adjustment column slidably connected inside the support column, and grooves arrayed on the surface of the adjustment column.

[0011] By adopting the above technical solution, the groove is used to hold the spring plate to fix the height between the shoulder pad and the violin.

[0012] Preferably, an auxiliary block is fixedly connected to the surface of the support column, and a groove is formed on the surface of the support column located inside the auxiliary block. A spring plate of a suitable size is movably connected inside the auxiliary block, the groove, and the groove. An auxiliary rotating shaft extending outside the auxiliary block is rotatably connected through both ends of the spring plate.

[0013] By adopting the above technical solution, the auxiliary rotating shaft is used to fix the position of the spring plate and prevent the spring plate from shifting when it is squeezed.

[0014] Preferably, the bottom of the adjusting column is fixedly connected to a circular plate that rotates inside the support foot.

[0015] By adopting the above technical solution, the size of the circular plate is larger than the size of the adjusting column to prevent the adjusting column from detaching from the support foot when rotating the adjusting column.

[0016] Preferably, a fixing block is fixedly connected to the surface of the main shaft at the end of the shoulder support pad away from the anti-slip pad, and a cylindrical groove extending into the interior of the main shaft is opened on one side of the surface of the fixing block, and a return spring is fixedly connected to the inner wall of the cylindrical groove.

[0017] By adopting the above technical solution, the return spring is used to keep the card plate inside the card slot, thereby improving the stability of the shoulder support pad.

[0018] Preferably, an auxiliary column that is fixedly connected to a reset spring is slidably connected inside the cylindrical groove, and a retaining plate is fixedly connected to the end of the auxiliary column away from the reset spring. A circular groove is formed on one side of the surface of the retaining plate.

[0019] By adopting the above technical solution, the card plate is used to control the fixed state of the shoulder support pad angle.

[0020] Preferably, a fixing post with a matching size is fixedly connected to one side of the surface of the fixing block, located inside the circular groove.

[0021] By adopting the above technical solution, the fixing column is used to restrict the card plate to only rotate.

[0022] Preferably, the fixed plate has a circumferential array of slots on one side of its surface, and the end of the plate away from the auxiliary column is located inside the slot and is adapted to its size.

[0023] By adopting the above technical solution, the slot and one end of the card plate are matched to avoid displacement of the main rotating shaft and improve the fixing effect.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By setting a rotatable connection between the shoulder rest and the main pivot, the height of one side of the shoulder rest, as well as the overall angle and height, can be adjusted independently. Adjusting the height of one side can change the angle between the instrument and the body, adapting to different playing postures.

[0026] 2. By using the adjusting post, groove, and spring plate, the height of the shoulder rest can be adjusted by rotating the adjusting post. The height adjustment direction of the shoulder rest is not the same as the support direction of the instrument body, which avoids the force applied by the hand during playing being directly transmitted to the adjustment components. The spring plate is locked inside the groove and the locking plate is located inside the slot, which can fix the height and angle of the shoulder rest. The shoulder rest can only be adjusted by rotating the adjusting post and pressing the spring plate at the same time, avoiding accidental height or angle changes caused by accidental touch. The double locking mechanism can effectively prevent the shoulder rest from accidentally loosening due to vibration or force during playing. Attached Figure Description

[0035] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0036] This application discloses a violin shoulder pad with adjustable height and angle.

[0037] Reference Figure 1 , Figure 2 An adjustable height and angle violin shoulder pad includes a shoulder support pad 1. A main rotating shaft 2 is rotatably connected to the bottom of both ends of the shoulder support pad 1, passing through both ends of the shoulder support pad 1 and allowing adjustment of the height of one end of the shoulder support pad 1. An anti-slip pad 3 is fixedly connected to the surface of one end of the shoulder support pad 1 near the main rotating shaft 2, located between the inner side of the main rotating shaft 2 and the outer side of one end of the shoulder support pad 1. Adjustment components 4 are provided at the top and bottom of the main rotating shaft 2, used to adjust the height and angle of the shoulder support pad 1. Support feet 5 are provided at the bottom of the adjustment components 4, used to secure the shoulder support pad 1 to the edge of the violin. Fixing plates 6 are fixedly connected to both sides of the end of the shoulder support pad 1 away from the anti-slip pad 3, located between the shoulder support pad 1 and the main rotating shaft 2. The rotational connection center of the main rotating shaft 2 and the shoulder support pad 1 is the same as the center of the fixing plate 6. Thus, when the angle of the shoulder support pad 1 changes, it drives the fixing plate 6 to rotate, and the locking plate 413 can always be locked inside the locking slot 416.

[0038] When installing the shoulder support pad 1, the support foot 5 needs to be gently placed on the lower edge of the violin back plate. When adjusting the height, the height of one side of the shoulder support pad 1 will rise or fall. When one end of the shoulder support pad 1 rises or falls, the fixing plate 6 will rotate. It is not necessary to adjust both ends of the shoulder support pad 1 at the same time. You only need to adjust the height of one side of the shoulder support pad 1 to change the angle between the shoulder support pad 1 and the violin and the height of one side.

[0039] Reference Figure 2 , Figure 5 The adjustment component 4 includes a support column 41 fixedly connected to the surface of the main rotating shaft 2, and an adjustment column 42 slidably connected inside the support column 41. The height of the main rotating shaft 2 can be adjusted by moving the adjustment column 42. The more part of the adjustment column 42 is inside the support column 41, the shorter the height between the shoulder pad 1 and the violin, and vice versa. The less part of the adjustment column 42 is inside the support column 41, the longer the height between the shoulder pad 1 and the violin. The surface of the adjustment column 42 has grooves 43 arranged in a vertical array. The distance between the grooves 43 is marked on the surface of the support column 41 to facilitate the user to adjust the height.

[0040] When the user adjusts the height between the main shaft 2 and the violin, the spring plate 47 is moved away from the inside of the groove 43 by rotating the adjusting column 42, so that the adjusting column 42 slides inside the support column 41 to adjust the required support height.

[0041] Reference Figure 2 , Figure 5 An auxiliary block 44 is fixedly connected to the bottom end of the surface of the support column 41. The auxiliary block 44 is located at the connection between the support column 41 and the adjusting column 42. A sliding groove 45 is formed through the surface of the support column 41 located inside the auxiliary block 44. The size of the sliding groove 45 is larger than the size of the groove 43. The inner sides of both the sliding groove 45 and the groove 43 are inclined, and the inclination angle of the sliding groove 45 is larger than that of the groove 43. A spring plate 47 is movably connected inside the auxiliary block 44, the sliding groove 45, and the groove 43. The middle part of the spring plate 47 protrudes and is V-shaped. The protruding part of the spring plate 47 is located inside the groove 43 and the sliding groove 45. The sliding groove 45 and the groove 43 are connected to the sliding groove 45 and the groove 42. The protruding section of the spring plate 47 is sized to fit the dimensions of the spring plate 47. An auxiliary rotating shaft 46 is rotatably connected through both ends of the spring plate 47. The auxiliary rotating shaft 46 extends outside the auxiliary block 44. The dimensions of the two ends of the auxiliary rotating shaft 46 outside the auxiliary block 44 are larger than the dimensions of the middle part of the auxiliary rotating shaft 46. In this way, the position of the auxiliary rotating shaft 46 will not shift during the compression of the spring plate 47, thus improving the stability of the height adjustment. A circular plate 48 is fixedly connected to the bottom of the adjusting column 42. The circular plate 48 rotates inside the support foot 5. The size of the circular plate 48 is larger than the size of the adjusting column 42. In this way, the adjusting column 42 will not shift during the adjustment process.

[0042] By rotating the adjusting column 42, the inner wall of the groove 43 presses the spring plate 47, causing it to move out of the groove 43. After the spring plate 47 leaves the inside of the groove 43, the adjusting column 42 can slide inside the support column 41 to adjust the height. When the height adjustment is completed, the adjusting column 42 is reversed so that the protruding part of the spring plate 47 is inserted into the groove 43 parallel to the spring plate 47, thereby fixing the adjusting column 42 and preventing the adjusting column 42 from moving.

[0043] Reference Figure 3 , Figure 4A fixing block 49 is fixedly connected to the top surface of the main rotating shaft 2 near the fixing plate 6. The fixing block 49 is U-shaped, and a cylindrical groove 410 is formed on the top surface of the fixing block 49. The cylindrical groove 410 extends into the interior of the main rotating shaft 2 to extend the height of the cylindrical groove 410. A return spring 411 is fixedly connected to the bottom of the inner wall of the cylindrical groove 410. The return spring 411 is used to keep the clamping plate 413 inside the clamping slot 416. An auxiliary post 414 is slidably connected inside the cylindrical groove 410. The bottom of the auxiliary post 414 is fixedly connected to the top of the return spring 411. The end of the auxiliary post 414 away from the return spring 411 is fixedly connected to the clamping plate 41. 3. A circular groove 415 is provided in the middle of the surface of the clamping plate 413. A fixed post 412 is rotatably connected inside the circular groove 415. The size of the fixed post 412 is adapted to the size of the circular groove 415, so that the clamping plate 413 does not wobble or deviate when rotating. The top of the surface of the fixed plate 6 is provided with a semi-circular array of clamping slots 416. The distance between the clamping slots 416 is related to the height of the adjusting groove 43. After each adjustment of the groove 43, the clamping plate 413 can accurately fit into the interior of one of the clamping slots 416. The end of the clamping plate 413 away from the auxiliary post 414 is located inside the clamping slot 416 and is adapted to its size. In this way, the angle of the main rotating shaft 2 can be stably fixed.

[0044] While the user rotates the adjusting column 42, the locking plate 413 is pressed at one end of the auxiliary column 414. The auxiliary column 414 moves into the cylindrical groove 410 and squeezes the reset spring 411. The end of the locking plate 413 near the auxiliary column 414 moves downward, and the end of the locking plate 413 away from the auxiliary column 414 tilts upward. A gap is provided between the fixing plate 6 and the top of the main rotating shaft 2 to facilitate the rotation of one end of the locking plate 413. When the locking plate 413 leaves the inside of the slot 416, the angle and height of one end of the shoulder support pad 1 can be adjusted.

[0045] The implementation principle of an adjustable height and angle violin shoulder pad according to an embodiment of this application is as follows: In the initial state, the return spring 411 is not compressed, one end of the retaining plate 413 is located inside the retaining groove 416, and the protruding section of the spring plate 47 is located inside the groove 43 and the slide 45. When the user needs to adjust the height of one end of the shoulder pad 1, he / she needs to press the end of the retaining plate 413 near the auxiliary column 414. The auxiliary column 414 presses the return spring 411 to deform it, and the other end of the retaining plate 413 lifts up and leaves the inside of the retaining groove 416. Then the user rotates the adjusting column 42, and the inner wall of the groove 43 squeezes the protruding section of the spring plate 47 to move it away from the inside of the groove 43. When the spring plate 47 leaves the inside of the groove 43, the user can move the adjusting column 42 up and down at will to the required height. The rotation adjustment direction of the shoulder pad 1 is not consistent with the vertical support direction of the violin body, which can avoid the force applied by the hand during playing being directly transmitted to the adjusting component 4.

[0046] When the adjusting column 42 moves up and down, it causes the shoulder support pad 1 to change angle. The shoulder support pad 1 causes the fixing plate 6 to rotate on the surface of the main shaft 2. By setting the shoulder support pad 1 and the main shaft 2 as a rotatable connection, the height of one side of the shoulder support pad 1 can be adjusted independently, thereby changing the angle between the instrument body and the shoulder support pad 1 to adapt to different playing postures. After the height is determined, the adjusting column 42 is reversed so that the protruding section of the spring plate 47 is inserted into the groove 43, thereby fixing the adjusting column 42 so that it cannot move. Then the user stops pressing one end of the locking plate 413. The return force of the return spring 411 pushes the auxiliary column 414 upward, causing one end of the fixed plate 413 to tilt up. The other end of the plate 413 is pressed down into the slot 416, fixing the angle of the shoulder support pad 1. The shoulder support pad 1 can only be adjusted by simultaneously rotating the adjusting column 42 and pressing the spring plate 47, which can avoid accidental changes in height or angle due to accidental touch. Then, the support foot 5 is gently placed on the lower edge of the violin back plate. During violin playing, the side of the shoulder support pad 1 away from the support foot 5 is located at the position from the shoulder to the collarbone.

[0047] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
