The present application claims priority to Japanese Patent Application No. 2023-77042, filed May 9, 2023, the contents of which are incorporated herein by reference.
The present disclosure relates to a holding structure and a holding device for a cymbal.
U.S. Pat. No. 11,170,745 (hereinafter referred to as Patent Document 1) discloses a quick release clamp (holding device) for easily holding a cymbal on a stand (cymbal stand). The quick release clamp has: an opening part through which the stand is inserted; a clamp jaw that changes the size of the opening part between a closed position and an open position, with the stand having been inserted through the opening part; an operator for changing the position of the clamp jaw; a housing in which the opening part, the clamp jaw, and the operator are arranged; and an elastic member provided between the operator and the housing.
In this quick release clamp, the operator is pressed and held in a predetermined position by the force of the elastic member, so that the operator holds the clamp jaw at the closed position. Moreover, the clamp jaw is moved from the closed position to the open position by operating the operator against the force of the elastic member. The clamp jaw is held at the closed position to thereby attach the quick release clamp to the stand. Furthermore, by moving the clamp jaw to the open position, the attachment of the quick release clamp to the stand is released.
When, in Patent Document 1, a cymbal is clamped between the quick release clamp and the supporting part of the stand, the form in which the cymbal is held changes as a result of the distance changing between the quick release clamp and the supporting part. For example, depending on the distance between the quick release clamp and the supporting part, the magnitude of the force that holds the cymbal between them changes. This changes the form in which the cymbal swings when the cymbal is struck.
However, in the quick release clamp of Patent Document 1, the female thread of the clamp jaw is configured to mesh with the male thread of the stand. Therefore, in order to reproduce the form in which the cymbal is held, it is necessary to adjust the distance between the quick release clamp and the supporting part every time the quick release clamp is attached to the stand. For this reason, it is difficult to reproduce the form in which the cymbal is held.
The present disclosure takes into consideration the above circumstances. One object of the present disclosure is to provide a holding structure and a holding device for a cymbal capable of easily reproducing a form in which a cymbal is held between the holding device and a supporting part of a cymbal stand.
An aspect of the present disclosure is a holding structure for a cymbal, including: a cymbal stand that includes: a rod configured to be insertable through a cymbal; and a supporting part that is provided on the rod, the supporting part being configured to support the cymbal through which the rod is inserted; and a holding device attachable to the rod, the holding device being configured to clamp the cymbal between the holding device and the supporting part supporting the cymbal. The holding device includes: an engaging part including an opening in which the rod is arranged in a state where the holding device is attached to the rod, the engaging part being configured to be engaged to the rod in a state of being immovable in a lengthwise direction of the rod; an adjusting part attached to the engaging part in a state of being movable relative to the engaging part in the lengthwise direction of the rod, the adjusting part being positioned between the engaging part and the supporting part in the state where the holding device is attached to the rod; and a pressing part. The adjusting part includes a sliding surface that is in contact with the engaging part, the sliding surface being configured to slide relative to the engaging part when the adjusting part moves relative to the engaging part. The pressing part is configured to suppress movement of the adjusting part, in the lengthwise direction of the rod, relative to the engaging part by pressing the sliding surface of the adjusting part against the engaging part.
Another aspect of the present disclosure is a holding device for a cymbal stand. The cymbal stand includes a rod configured to be insertable through a cymbal and a supporting part that is provided on the rod, the supporting part being configured to support the cymbal through which the rod is inserted, the holding device being configured to be attachable to the rod, and the holding device being configured to clamp the cymbal between the holding device and the supporting part supporting the cymbal. The holding device includes: an engaging part including an opening in which the rod is arranged in a state where the holding device is attached to the rod, the engaging part being configured to be engaged to the rod in a state of being immovable in a lengthwise direction of the rod; an adjusting part attached to the engaging part in a state of being movable relative to the engaging part in the lengthwise direction of the rod, the adjusting part being positioned between the engaging part and the supporting part in the state where the holding device is attached to the rod; and a pressing part. The adjusting part includes a sliding surface that is in contact with the engaging part, the sliding surface being configured to slide relative to the engaging part when the adjusting part moves relative to the engaging part. The pressing part is configured to suppress movement of the adjusting part, in the lengthwise direction of the rod, relative to the engaging part by pressing the sliding surface of the adjusting part against the engaging part.
Hereinafter, embodiments of the present disclosure will be described, with reference to
As shown in
The cymbal stand 1 includes a rod 11 and a supporting part 12. The rod 11 is inserted through a cymbal CY. The supporting part 12 is provided on the rod 11 and supports the cymbal CY, through which the rod 11 is inserted.
As shown in
The distal end part of the rod 11 has an inclined surface 11a. The inclined surface 11a of the rod 11 slopes toward the distal end side of the rod 11, with approaching toward the inner side from the outer side of the rod 11 in the radial direction. That is to say, the distal end part of the rod 11 is formed in a tapered shape. The inclined surface 11a of the rod 11 is positioned closer to the distal end side of the rod 11 than the engaging recess 13 mentioned above.
The distal end part of the rod 11 has a plurality of inclined surfaces 11a (two in the example of the drawings). The plurality of inclined surfaces 11a are arranged at intervals in the circumferential direction of the rod 11. The number of the inclined surfaces 11a of the rod 11 in the example shown in the drawings corresponds to the number of the engaging recesses 13 mentioned above. Moreover, the positions of the inclined surfaces 11a in the circumferential direction of the rod 11 correspond to the positions of the engaging recesses 13. It should be noted that the inclined surfaces 11a of the rod 11 may be formed over the entire circumference of the rod 11, for example.

As shown in
The housing 22 includes the opening 21, in which the rod 11 is arranged. The housing 22 has an accommodating portion 25 in which the moving member 23 and the elastic member 24 are accommodated, and an attachment portion 26 to which the adjusting part 30, which will be described later, is attached. The accommodating portion 25 and the attachment portion 26 are arranged in the extending direction (Z-axis direction) of the opening 21 corresponding to the lengthwise direction of the rod 11. The opening 21 of the housing 22 is provided across the accommodating portion 25 and the attachment portion 26.
The accommodating portion 25 has an internal space 251 that can accommodate the moving member 23 and the elastic member 24. The internal space 251 communicates with the opening 21 of the housing 22. Moreover, the accommodating portion 25 has an exposing opening 252 for allowing a part of the moving member 23 arranged in the internal space 251 to be exposed to the outside of the housing 22. The exposing opening 252 faces one side (X-axis positive direction side) in an orthogonal direction that is orthogonal to the extending direction (Z-axis direction) of the opening 21.
The adjusting part 30 is attached to the attachment portion 26 so as to be movable in the lengthwise direction of the rod (Z-axis direction). The attachment portion 26 has a sliding surface 26a that makes surface contact with the adjusting part 30 and slides when the adjusting part 30 moves relative to the attachment portion 26. In the attachment portion 26 of the present embodiment, the adjusting part 30 has a first thread 261 the axis of which extends along the lengthwise direction of the rod 11. The surface of this first thread 261 is the sliding surface 26a of the attachment portion 26 mentioned above.
The attachment portion 26 of the present embodiment is formed in a cylindrical shape extending from the accommodating portion 25 in the lengthwise direction of the rod 11 (Z-axis negative direction). The attachment portion 26 is smaller than the accommodating portion 25 when viewed from the lengthwise direction of the rod 11. The first thread 261 of the attachment portion 26 is provided on the outer circumferential surface of the attachment portion 26, which is of a cylindrical shape. That is to say, the first thread 261 is a male thread.
The moving member 23 is arranged in the internal space 251 of the housing 22 (inside the housing 22). The moving member 23 is movable within the housing 22 between an engaging position (locking position) P1 and a release position P2 (see
In the present embodiment, the moving member 23 is movable within the housing 22 between the engaging position (locking position) P1 and the release position P2 in a direction orthogonal to the housing 22 (X-axis direction). The direction in which the moving member 23 is moved from the release position P2 to the engaging position P1 is a direction toward one side of the orthogonal direction (X-axis positive direction side), and the direction in which the moving member 23 is moved from the engaging position P1 to the release position P2 is a direction toward the other side of the orthogonal direction (X-axis negative direction side). It should be noted that the direction in which the moving member 23 is moved from the release position P2 to the engaging position P1 may be, for example, the direction toward the other side of the orthogonal direction (X-axis negative direction side).
A part of the moving member 23 is arranged so as to be exposed to the outside from the exposing opening 252 of the housing 22. This allows the user of the holding device 2 to operate the moving member 23. For example, when the user of the holding device 2 presses the moving member 23 toward the inside of the housing 22 with their fingers, the moving member 23 can be moved to the other side in the orthogonal direction, that is, the moving member 23 can be moved from the engaging position P1 toward the release position P2.
The retaining pin 27 attached to the housing 22 restricts the movement of the moving member 23 from the engaging position P1 toward one side of the orthogonal direction. As a result, it is possible to prevent the moving member 23 from moving further from the engaging position P1 toward the one side of the orthogonal direction and falling out of the housing 22 from the exposing opening 252.
The moving member 23 has an engaging protrusion part (engaging protrusion part, locking protrusion) 231. As shown in
As shown in
The elastic member 24 biases the moving member 23 toward the engaging position P1. In the internal space 251 of the housing 22, the elastic member 24 is arranged adjacent to the other side in the orthogonal direction (X-axis negative direction side) of the moving member 23, and is clamped between the inner surface of the housing 22 and the moving member 23. As a result, the elastic member 24 biases the moving member 23 to the one side in the orthogonal direction (X-axis positive direction side). The elastic member 24 in the example shown in the drawings is a coil spring, however, it may be made of rubber, for example.
The adjusting part 30 is detachably attached to the engaging part 20. The adjusting part 30 attached to the engaging part 20 is movable relative to the engaging part 20 in the lengthwise direction of the rod 11 (Z-axis direction). The adjusting part 30 has a sliding surface 30a that is in surface contact with the sliding surface 26a of the engaging part 20 and slides when moving relative to the engaging part 20. The adjusting part 30 of the present embodiment has a second thread 31 that meshes with the first thread 261 of the engaging part 20. The surface of the second thread 31 that is in surface contact with the first thread 261 is the sliding surface 30a of the adjusting part 30. By rotating the adjusting part 30 relative to the engaging part 20 with the second thread 31 meshed with the first thread 261, the adjusting part 30 moves in the lengthwise direction of the rod 11 relative to the engaging part 20.
The adjusting part 30 of the present embodiment is formed in a cylindrical shape. The second thread 31 of the adjusting part 30 is provided on the inner circumferential surface of the adjusting part 30, which is of a cylindrical shape. That is to say, the second thread 31 is a female thread.
The adjusting part 30 of the present embodiment has an accommodating recess part 32 in which a pressing part 40, which will be described later, is accommodated. The accommodating recess part 32 opens at an opposing surface 30b of the adjusting part 30 that faces the accommodating portion 25 of engaging part 20 in the lengthwise direction of the rod 11 when the adjusting part 30 is attached to the engaging part 20. As shown in
The adjusting part 30 is located in the direction (Z-axis negative direction) with respect to the engaging part 20 in which the rod 11 is removed from the opening 21 of the engaging part 20. For this reason, as shown in
As shown in
As shown in
The pressing part 40, which is a coil spring, is accommodated in the accommodating recess part 32 of the adjusting part 30 formed in a ring shape. In a state where the adjusting part 30 is attached to the engaging part 20, the pressing part 40 is clamped between the accommodating portion 25 of the engaging part 20 and the bottom surface of the accommodating recess part 32 of the adjusting part 30. In this state, the pressing part 40 is hardly exposed, thereby ensuring the protection of the pressing part 40. It should be noted that the pressing part 40 is not limited to a coil spring, and may be made of, for example, rubber.
Next, an example of the usage method of the holding device 2 provided in the holding structure for a cymbal of the present embodiment will be described.
As shown in
When attaching the holding device 2 to the rod 11, then as shown in
As a result, as shown in
Through the above process, attachment of the holding device 2 to the cymbal stand 1 is completed.
As shown in
When removing the holding device 2 from the rod 11, then as shown in
As described above, since the holding device 2 does not need to be rotated relative to the rod 11, the holding device 2 can be easily attached to and detached from the rod 11 in a short period of time.
As described above, according to the holding structure and the holding device 2 for a cymbal of the present embodiment, the holding device 2 has the pressing part 40 that presses the sliding surface 30a of the adjusting part 30 against the engaging part 20 to suppress movement of the adjusting part 30 in the lengthwise direction of the rod 11 relative to the engaging part 20. Therefore, when moving the adjusting part 30 relative to the engaging part 20, frictional force is generated between the sliding surface 30a of the adjusting part 30 and the engaging part 20, thereby suppressing the adjusting part 30 from moving relative to the engaging part 20. As a result, it is possible to suppress unwanted changes in the positional relationship between the engaging part 20 and the adjusting part 30. That is to say, unwanted changes in the distance between the holding device 2 attached to the rod 11 and the supporting part 12 are suppressed, whereby unwanted changes are suppressed in the form of holding the cymbal CY between the holding device 2 and the supporting part 12.
Since the positional relationship between the engaging part 20 and the adjusting part 30 is suitably maintained by the pressing part 40 of the holding device 2, even when the holding device 2 is removed from the rod 11 and then re-attached to the rod 11, the distance between the holding device 2 and the supporting part 12 can be easily reproduced. In other words, it is possible to easily reproduce the form in which the cymbal CY is held between the holding device 2 and the supporting part 12.
Moreover, in the holding structure and the holding device 2 for a cymbal of the present embodiment, by rotating the adjusting part 30 relative to the engaging part 20 with the second thread 31 of the adjusting part 30 meshed with the first thread 261 of the engaging part 20, the adjusting part 30 moves in the lengthwise direction of the rod 11 relative to the engaging part 20. Moreover, the pressing part 40 presses the surface of the second thread 31 against the surface of the first thread 261 in the lengthwise direction of the rod 11. As a result, when rotating the second thread 31 of the adjusting part 30 relative to the first thread 261 of the engaging part 20, a large frictional force is generated between the first and second threads 261, 31. This frictional force enables effective suppression of unwanted changes in the positional relationship between the engaging part 20 and the adjusting part 30.
Furthermore, the mechanism for moving the adjusting part 30 in the lengthwise direction of the rod 11 relative to the engaging part 20 is constituted by the first and second threads 261, 31, whereby the relative positional relationship between the engaging part 20 and the adjusting part 30 can be adjusted even more precisely.
Moreover, in the holding structure and the holding device 2 for a cymbal of the present embodiment, the moving member 23 can be held at the engaging position P1 by the elastic member 24. As a result, it is possible to effectively suppress unwanted release of the engaging (locking) state of the holding device 2 from the rod 11.
In addition, by simply moving the moving member 23 from the engaging position P1 to the release position P2 against the biasing force of the elastic member 24, the engaging (locking) state of the holding device 2 on the rod 11 can be easily released. In other words, the holding device 2 can be easily attached to and detached from the rod 11.
Moreover, in the holding structure and the holding device 2 for a cymbal of the present embodiment, the engaging protrusion 231 of the moving member 23 has the inclined surface 23 la that faces in the direction in which the rod 11 is removed from the opening 21 of the housing 22, and that slopes in the direction in which the rod 11 is inserted into the opening 21, with approaching toward the protruding direction of the engaging protrusion 231. As a result, by simply inserting the rod 11 into the opening 21 of the engaging part 20, the distal end of the rod 11 presses the inclined surface 231a of the engaging protrusion 231 positioned at the engaging position P1, whereby the moving member 23 can be moved from the engaging position P1 to the release position P2 against the biasing force of the elastic member 24. In other words, the rod 11 can be easily arranged through the opening 21 of the engaging part 20.
Moreover, in the holding structure and the holding device 2 for a cymbal of the present embodiment, the distal end part of the rod 11 has the inclined surface 11a that slopes toward the distal end side of the rod 11, with approaching toward the inner side from the outer side of the rod 11 in the radial direction. As a result, by simply inserting the rod 11 of the cymbal stand 1 into the opening 21 of the engaging part 20, the inclined surface 11a of the rod 11 presses the engaging protrusion 231 positioned at the engaging position P1, whereby the moving member 23 can be moved from the engaging position P1 to the release position P2 against the biasing force of the elastic member 24. In other words, the rod 11 can be easily inserted through the opening 21 of the engaging part 20.
Moreover, in the holding structure for a cymbal of the present embodiment, the rod 11 has the engaging recess 13 that is recessed from the side surface thereof and into which the engaging protrusion 231 is inserted. As a result, upon having inserted the rod 11 into the opening 21 of the engaging part 20, by arranging the moving member 23 at the engaging position P1 and inserting the engaging protrusion 231 into the engaging recess 13 of the rod 11, the holding device 2 can be engaged (locked) onto the rod 11. Moreover, since the moving member 23 is held at the engaging position P1 by the elastic member 24, it is possible to effectively suppress the engaging protrusion 231 of the moving member 23 from exiting from the engaging recess 13 of the rod 11. This makes it possible to suppress the holding device 2 from detaching from the rod 11, in contrast to the case of attaching the holding device 2 to the rod 11 by means of a screw thread as practiced conventionally. In addition, by simply moving the moving member 23 from the engaging position P1 to the release position P2 against the biasing force of the elastic member 24, the engaging protrusion 231 of the moving member 23 can be easily removed from the engaging recess 13 of the rod 11. In other words, the holding device 2 can be easily attached to and detached from the rod 11.
Moreover, in the holding structure for a cymbal of the present embodiment, the engaging recess 13 of the rod 11 is formed in a part of the side surface of the rod 11 in the circumferential direction. Therefore, when the engaging protrusion 231 of the engaging part 20 is inserted into the engaging recess 13 of the rod 11, it is possible to prevent the engaging part 20 from rotating in the circumferential direction relative to the rod 11. As a result, the distance between the holding device 2 and the supporting part 12 of the cymbal stand 1 can be easily adjusted while the holding device 2 is still attached to the rod 11. This point will be described below.
In order to adjust the distance between the holding device 2 and the supporting part 12 while the holding device 2 is still attached to the rod 11, the adjusting part 30 of the holding device 2 is rotated relative to the engaging part 20 around the lengthwise direction of the rod 11 serving as the rotation axis thereof. Here, as described above, when the holding device 2 is attached to the rod 11, rotation of the engaging part 20 relative to the rod 11 is prevented. Therefore, by simply pinching and rotating only the adjusting part 30 of the holding device 2 with fingers, the adjusting part 30 can be easily rotated relative to the engaging part 20, and as a result, the adjusting part 30 can be moved relative to the engaging part 20 in the lengthwise direction of the rod 11. In other words, the distance between the holding device 2 and the supporting part 12 can be easily adjusted with one hand.
The present disclosure has been described in detail above, however, the present disclosure is not limited to the above embodiments, and various modifications may be made without departing from the scope of the present disclosure.
In the present disclosure, for example, the first thread 261 of the engaging part 20 may be a female thread, and the second thread 31 of the adjusting part 30 that meshes with the first thread 261 may be a male thread.
In the present disclosure, the adjusting part 30 may simply move in the lengthwise direction of the rod 11 relative to the engaging part 20, for example.
In the present disclosure, it is sufficient that the moving member 23 is movable at least relative to the housing 22 in a direction intersecting the lengthwise direction of the rod 11. In other words, the moving member 23 may be movable relative to the housing 22 in a direction inclined to the lengthwise direction of the rod 11.
According to the present disclosure, it is possible to easily reproduce a form in which a cymbal is held between a holding device and a supporting part of a cymbal stand.
