Further, a lubricant 22 such as grease is sealed between the rotating body 11 and the inner housing 14. Thereby, the rotating body 11 is rotatably disposed inside both the outer housing 13 and the inner housing 14.

  As shown in FIGS. 5 and 6, the brake spring 12 is a torsion coil spring and has a coil portion 23. The brake spring 12 is configured such that the shaft portion 20 of the rotating body 11 is inserted into the coil portion 23 in a state where the coil portion 23 is disposed in the cylindrical shaft 17 of the inner housing 14.

  Further, as shown in FIGS. 5 and 6, the brake spring 12 has one end portion 23 a (upper end portion in FIG. 5) of the coil portion 23 inserted into a mounting hole 20 a provided in the upper portion of the shaft portion 20. While being locked, the other end 23 b (lower end in FIG. 5) protrudes downward from the cylindrical shaft 17 of the inner housing 14 and is fixed to the lower surface of the bottom plate 14 b of the inner housing 14. Thereby, the braking spring 12 is attached to both the rotating body 11 and the inner housing 14.

  For this reason, as shown in FIGS. 5 and 6, the brake spring 12 is in a neutral state when the coil portion 23 is in a free state, and the rotating body 11 is unidirectional in this neutral state, for example, the arrow X shown in FIG. When rotated in the direction, as shown in FIG. 7, the outer diameter of the coil portion 23 is configured to gradually shrink and become smaller.

  That is, when the rotating body 11 rotates in the direction of the arrow X shown in FIG. 8, the braking spring 12 is gradually separated from the inner peripheral surface of the cylindrical shaft 17 of the inner housing 14 as shown in FIG. 11 is configured to elastically deform so as to gradually approach the outer peripheral surface of the shaft portion 20. Thereby, the brake spring 12 is configured to gradually increase the load acting to return the rotating body 11 to the neutral state, as shown by the solid line on the right side in FIG.

  Further, as shown in FIGS. 5 and 6, the brake spring 12 rotates in the direction opposite to the above-described direction, for example, the arrow Y direction shown in FIG. Then, as shown in FIG. 9, the outer diameter of the coil portion 23 is configured to gradually expand and increase.

  That is, the brake spring 12 is gradually separated from the outer peripheral surface of the shaft portion 20 of the rotating body 11 when the rotating body 11 rotates in the arrow Y direction shown in FIG. The cylindrical shaft 17 is elastically deformed so as to gradually approach the inner peripheral surface of the cylindrical shaft 17. As a result, the brake spring 12 is configured to gradually increase the load acting to return the rotating body 11 to the neutral state, as shown by the solid line on the left side in FIG.

  In this way, as shown by a solid line in FIG. 11, the braking spring 12 has the rotating body 11 in one direction (positive direction), that is, the arrow shown in FIG. When rotating in the X direction, the load acting to return the rotating body 11 to the neutral state is gradually increased by gradually contracting and deforming along with the rotation.

  Further, as shown by a solid line in FIG. 11, the brake spring 12 is rotated when the rotating body 11 rotates in the reverse direction (negative direction), that is, in the arrow Y direction shown in FIG. Accordingly, by gradually expanding and deforming, the load acting to return the rotating body 11 to the neutral state is gradually increased.

  By the way, as shown in FIG. 5, such a braking device 5 is configured such that the guitar 4 is detachably attached. That is, as shown in FIGS. 1 to 5, the damper member 8 of the braking device 5 is provided with the mounting portion 24 on the rotating body 11, and the mounting portion 25 of the guitar 4 is detachably attached to the mounting portion 23. It is configured.

  In this case, the mounting portion 25 of the guitar 4 is made of a high-strength metal or synthetic resin, and is provided on the mounting plate 26 attached to the back surface of the guitar 4 with screws 26a as shown in FIG. And an attached mounting shaft 27. As shown in FIG. 12, a protrusion 27a for preventing rotation is provided on the outer peripheral surface of the mounting shaft 27 along the axial direction. Further, as shown in FIGS. 13A and 13B, a mounting groove 27b is formed in a ring shape along the circumferential direction on the outer peripheral surface of the mounting shaft 27. A ring-shaped lock member 28 that expands and contracts in the radial direction is attached to the mounting groove 27b.

  When the metal round bar is rounded into a circular shape, the lock member 28 is formed in a substantially non-continuous ring shape by rounding with a gap between both ends. Accordingly, the lock member 28 is configured to contract in the radial direction when an external force is applied from the outer peripheral side toward the central portion. That is, when the lock member 28 is in a free state where no external force is applied, the outer periphery thereof is formed larger than the outer periphery of the mounting shaft 27 as shown in FIG. Is also formed small.

  Thereby, as shown in FIG. 13A, when the lock member 28 is mounted in the mounting groove 27b of the mounting shaft 27, the outer peripheral side protrudes from the outer peripheral surface of the mounting shaft 27, and the inner peripheral side is in the mounting groove 27b. Inserted and attached to the mounting groove 2b of the mounting shaft 27 in this state. Further, when an external force is applied from the outer peripheral side toward the central portion, the lock member 28 contracts in the radial direction as shown in FIG. 13B, and is immersed in the mounting groove 27b of the mounting shaft 27. The outer peripheral surface is configured to be substantially the same as the outer peripheral surface of the mounting shaft 27.

  On the other hand, the mounting portion 24 provided on the rotating body 11 of the damper member 8 to which the mounting portion 25 of the guitar 4 is attached projects upward through the circular hole 13c of the flange portion 13b of the outer housing 13, as shown in FIG. Yes. As shown in FIGS. 12 and 13, the mounting portion 24 has a circular shaft mounting hole 30 in which the mounting shaft 27 of the mounting portion 25 of the guitar 4 is mounted. The shaft mounting hole 30 is provided open on the upper surface side in a state corresponding to the shaft portion 20 of the rotating body 11 which is the rotation center portion of the rotating body 11.

  As shown in FIG. 12, a rotation stop groove 30a into which the protrusion 27a of the mounting shaft 27 of the guitar 4 is inserted is provided on the inner peripheral surface of the shaft mounting hole 30 along the axial direction. As a result, the mounting portion 24 is configured such that the mounting shaft 27 of the guitar 4 is inserted into the shaft mounting hole 30 of the rotating body 11 and the protrusion 27a of the mounting shaft 27 of the guitar 4 is inserted into the rotation stop groove 30a. 4 is transmitted to the rotating body 11, and the rotating body 11 is rotated in accordance with the movement of the guitar 4 in the rotating direction.

  Further, as shown in FIGS. 13 (a) and 13 (b), a lock member 28 attached to the attachment shaft 27 of the guitar 4 is detachably engaged with the inner peripheral surface of the shaft mounting hole 30. A locking groove 30b is provided along the circumferential direction. As a result, as shown in FIG. 13 (b), the mounting portion 24 is locked by the inner peripheral surface of the shaft mounting hole 30 when the mounting shaft 27 of the guitar 4 is inserted into the shaft mounting hole 30 of the rotating body 11. 28 is contracted so as to be immersed in the mounting groove 27 b of the mounting shaft 27.

  Further, as shown in FIG. 13A, when the mounting member 24 corresponds to the locking groove 30b of the shaft mounting hole 30 with the lock member 28 contracted, the locking member 28 is elastically restored and the shaft mounting hole is restored. It is comprised so that it may fit in 30 latching grooves 30b. As a result, the mounting portion 24 attaches the mounting shaft 27 of the guitar 4 to the shaft mounting hole 30 of the rotating body 11, and transmits the movement of the guitar 4 in the rotating direction to the rotating body 11 in this state. The rotating body 11 is configured to rotate according to the movement.

  Further, when the mounting shaft 24 of the guitar 4 is extracted from the shaft mounting hole 30 in a state where the lock member 28 is fitted in the locking groove 30b of the shaft mounting hole 30, the mounting portion 24 is shown in FIG. As shown, by pulling out the mounting shaft 27 of the guitar 4 in the direction of pulling out from the shaft mounting hole 30 against the elastic force of the locking member 28, the locking member 28 is contracted from the locking groove 30 b of the shaft mounting hole 30. The mounting shaft 27 of the guitar 4 is pulled out from the shaft mounting hole 30 by being detached.

Next, the operation of the instrument support belt 1 will be described.
First, the instrument support belt 1 is attached to the performer 2's waist. At this time, as shown in FIG. 1, the belt body 3 is wound around the player 2 and the braking device 5 is arranged in front of the player 2, and in this state, both ends of the belt body 3 are attached by the fasteners 6. . Then, the guitar 4 is attached to the braking device 5.

  At this time, since the mounting portion 21 of the rotating body 11 in the damper member 8 of the braking device 5 attached to the belt body 3 is exposed to the outside, the exposed shaft mounting hole 30 of the mounting portion 21 of the rotating body 11 is exposed. Then, the mounting shaft 27 of the mounting portion 25 provided on the back surface of the guitar 4 is inserted. That is, the protrusion 27a provided on the outer peripheral surface of the mounting shaft 27 of the guitar 4 is made to correspond to the rotation stop groove 30a provided on the inner peripheral surface of the shaft mounting hole 30 of the mounting portion 21, as shown in FIG. The mounting shaft 27 of the guitar 4 is inserted into the shaft mounting hole 30 of the mounting portion 21 of the rotating body 11.

  Then, as shown in FIG. 13 (b), the inner peripheral surface of the shaft mounting hole 30 contracts the lock member 28 attached to the mounting shaft 27 of the guitar 4 in the radial direction to enter the mounting groove 27 b of the mounting shaft 27. Immerse yourself. In this state, the mounting shaft 27 of the guitar 4 is inserted into the shaft mounting hole 30 of the mounting portion 21 of the rotating body 11. When the contracted lock member 28 corresponds to the locking groove 30b of the shaft mounting hole 30, the lock member 28 is elastically restored as shown in FIG. It fits into the locking groove 30b.

  Thereby, the mounting shaft 27 of the guitar 4 is attached to the mounting portion 21 of the rotating body 11. In this state, the movement of the guitar 4 in the rotation direction is transmitted to the rotation body 11, and the rotation body 11 rotates according to the movement of the guitar 4 in the rotation direction. Further, at this time, the player 2 is likely to play the guitar 4 most easily, that is, as shown in FIG. Attach to the mounting portion 21.

  Thus, the guitar 4 is attached to the braking device 5 at the neutral position of the braking spring 12 of the damper device 8. In this state, the player 2 can play the guitar 4 satisfactorily. Thus, when the performer 2 plays the guitar 4, the performer 2 performs while moving the body vigorously, or while continuously operating the fret portion 4 a of the guitar 4 from the low range to the high range. May play. In such a case, the angle of the guitar 4 changes according to the movement of the player 2, the operation position of the fret portion 4a, etc., and the guitar 4 rotates. At this time, the movement of the guitar 4 in the rotational direction can be braked by the damper member 8 of the braking device 5.

  For example, when the guitar 4 is rotated in the direction in which the fret portion 4a of the guitar 4 is pushed up, the outer diameter of the coil portion 23 of the brake spring 12 is gradually reduced and reduced, as shown in FIGS. The elastic body is elastically deformed so as to gradually approach the outer peripheral surface of the shaft portion 20 of the rotating body 11. As a result, the load applied to the brake spring 12 so as to return the rotating body 11 to the neutral state is gradually increased, so that a load is applied to the guitar 4. For this reason, when the guitar 4 is returned to the neutral state where it is most likely to be played, the guitar 4 can be easily returned to the neutral state by the spring force of the brake spring 12.

  Further, when the guitar 4 is rotated in the direction in which the fret portion 4a of the guitar 4 is pushed down, as shown in FIGS. 9 and 10, the outer diameter of the coil portion 23 of the braking spring 12 gradually increases and becomes larger. The inner housing 14 is elastically deformed so as to gradually approach the inner peripheral surface of the cylindrical shaft 17. As a result, the load applied to the brake spring 12 so as to return the rotating body 11 to the neutral state is gradually increased, so that a load is applied to the guitar 4. For this reason, when the guitar 4 is returned to the neutral state where it is most likely to be played, the guitar 4 can be easily returned to the neutral state by the spring force of the brake spring 12.

  Accordingly, when the performer 2 performs while moving his / her body vigorously, or when performing the fret portion 4a of the guitar 4 while continuously operating from the low range to the high range, the movement of the performer 2 and the fret portion Even if the guitar 4 is moved in the direction of rotation according to the operation position of 4a, it can be easily returned by the spring force of the brake spring 12 when returning the guitar 4 to the neutral state where it is most likely to be played. However, the player 2 can perform well without the shoulders and neck of the performer 2 sticking.

  As described above, according to the musical instrument support belt 1, the braking device 5 to which the guitar 4 is attached is provided on the belt body 3 that is detachably attached to the body of the player 2, and the braking device 5 attaches the guitar 4. When the performance of the guitar 4 is performed, the operation in the rotational direction of the guitar 4 is braked. Therefore, when the guitar 4 is attached to the body of the performer 2 and the performance is performed, the braking device 5 moves in the rotational direction of the guitar 4. Therefore, the guitar 4 can be prevented from wobbling with respect to the player 2, and the guitar 4 can be stabilized with respect to the player 2, so that the guitar 4 can be played well.

  In this case, the load of the guitar 4 is not applied to the shoulder or neck of the player 2 by attaching the belt body 3 to the waist of the player 2 and attaching the guitar 4 to the braking device 5 of the belt body 3. For this reason, even if it plays for a long time, it can prevent that the shoulder and neck of the player 2 remain, and can perform well.

  Further, in this musical instrument support belt 1, the player 5 has a neutral state in which a load is hardly applied in the rotation direction of the guitar 4 and is always urged to return to the neutral state. When the player 2 performs while moving the body vigorously, or when performing the fret part 4a of the guitar 4 while continuously operating from the low range to the high range, the movement of the player 2, the operation position of the fret part 4a, etc. Accordingly, even if the guitar 4 is moved in the direction of rotation, it can be easily returned by the spring force of the brake spring 12 when returning the guitar 4 to the neutral state where it is most likely to be played. It is possible to perform well without suffering from the shoulder and neck of the 2nd.

  In this case, the braking device 5 includes a base member 7 attached to the belt main body 3 and a damper member 8 provided on the base member 7 to which the guitar 4 is detachably attached. Therefore, the guitar 4 is attached. The damper member 8 can be easily attached to the belt body 3 by the base member 7. That is, since the base member 7 is provided with through holes 7a and 7b through which the belt body 3 passes on both side portions thereof, penetrating from both side portions of the base member 7 toward the back surface of the base member 7. The base member 7 can be easily attached to the belt body 3 simply by passing the belt body 3 through 7a and 7b.

  The damper device 8 includes a housing 10, a rotating body 11 that is rotatably disposed in the housing 10, and a braking spring 12 for braking the rotation of the rotating body 11. The rotating body 11 can always be urged to return to the neutral state by the 12 spring force. That is, the brake spring 12 is a torsion coil spring and has a coil portion 23. One end portion 23a (upper end portion in FIG. 4) of the coil portion 23 is locked to the shaft portion 20, and the other end portion 23b (FIG. 4 is fixed to the inner housing 14, the coil portion 23 is in a neutral state when the coil portion 23 is in a free state, and the rotating body 11 is always returned to the neutral state by the spring force of the coil portion 23. You can

  Therefore, according to this damper member 8, when the rotating body 11 rotates in one direction from the neutral state, the rotating body 11 is neutralized by elastically deforming so that the outer diameter of the coil portion 23 gradually decreases and becomes smaller. The load acting to return to the state can be gradually increased, and when the rotating body 11 rotates in the reverse direction from the neutral state, the outer diameter of the coil portion 23 is elastically deformed so as to gradually increase and increase. Thereby, the load which acts so that the rotary body 11 may be returned to a neutral state can be increased gradually. For this reason, the rotating body 11 can always be urged to return to the neutral state by the spring force of the coil portion 23.

  Moreover, according to this musical instrument support belt 1, since the braking device 5 is provided with the attachment part 24 for attaching the attachment part 25 provided in the guitar 4 so that attachment or detachment is possible, the belt main body 3 is attached to the player's 2 body. The guitar 4 can be attached to the braking device 5 while being attached to the brake device 5, and the guitar 4 can be detached from the braking device 5, thereby providing a user-friendly device.

  In this case, the attachment portion 25 of the guitar 4 includes an attachment plate 26 attached to the back surface of the guitar 4 and an attachment shaft 27 provided on the attachment plate 26, and the attachment shaft 27 is circular on the outer peripheral surface thereof. A mounting groove 27b provided in a ring shape along the circumferential direction and a ring-shaped lock member 28 that is attached to the mounting groove 27b and expands and contracts in the radial direction are provided. Since the shaft mounting hole 30 provided in the rotating body 11 and the locking groove 30b provided in the inner peripheral surface of the shaft mounting hole 30 are provided, the guitar is placed in the shaft mounting hole 30 of the mounting portion 24. The guitar 4 can be easily and easily attached to the braking device 5 simply by inserting the four attachment shafts 27.

  That is, when the mounting shaft 27 of the mounting portion 25 provided on the back surface of the guitar 4 is inserted into the shaft mounting hole 30 of the mounting portion 21 of the rotating body 11, the inner peripheral surface of the shaft mounting hole 30 is the guitar 4. The lock member 28 attached to the attachment shaft 27 is contracted in the radial direction so as to be immersed in the attachment groove 27b of the attachment shaft 27, and the lock member 28 in the contracted state in this state enters the locking groove 30b of the shaft attachment hole 30. If it respond | corresponds, since the lock member 28 will elastically return, the outer peripheral part of the lock member 28 can be fitted in the latching groove 30b of the shaft mounting hole 30. For this reason, the guitar 4 can be easily and easily attached to the braking device 5 simply by inserting the attachment shaft 27 of the guitar 4 into the shaft attachment hole 30 of the attachment portion 21 of the rotating body 11.

  Further, when the guitar 4 is removed from the braking device 5, if the mounting shaft 27 of the guitar 4 is pulled out in the direction of extracting from the shaft mounting hole 30 against the elastic force of the locking member 28, the locking member 28 contracts in the radial direction. However, the mounting shaft 27 of the guitar 4 can be easily pulled out from the shaft mounting hole 30, so that the guitar 4 can be easily and easily removed from the braking device 5. be able to.
