Description:
TECHNICAL FIELD 
     The present invention relates to a holding structure that holds a cymbal on a cymbal supporting rod, and particularly to a cymbal holding structure that has a fastener that does not get loosened during a performance, has excellent operability in adjustment of fastening force applied to a cymbal and attachment/detachment of the cymbal, and can be suitably used in a high-hat stand and a cymbal stand having the cymbal holding structure. 
     BACKGROUND ART 
     In various cymbal stands such as a high-hat stand in which two upper and lower cymbals are brought to butt against each other by a stepping-on operation of a pedal and a cymbal stand in which each cymbal is independently arranged thereon to play the cymbal, there has been conventionally employed a holding structure for holding a cymbal on a cymbal supporting rod in which a fastener having a screw hole is screwed with a bolt portion of the cymbal supporting rod, and the cymbal is fastened through a felt washer or the like (for example, refer to Patent Documents 1 to 3). 
     Since cymbals in these stands largely vibrate due to striking impact received during a performance, a fastener easily gets loosened. Especially in a high-hat stand, large vibration is generated due to butting between upper and lower cymbals. Therefore, in order to prevent a fastener from getting loosened, a double nut structure is employed in an upper cymbal holding structure for holding the cymbal. Further, since even such a double nut structure is not sufficient to prevent the loosening of a fastener, there has also been proposed a structure that includes a cutout groove which communicates with a screw hole to be screwed with a bolt portion of a cymbal supporting rod, and a pair of screw mounting units which are opposed to each other across the cutout groove. In this structure, these screw mounting units are connected to each other by a fastening screw to narrow a distance between the mounting units so that the screw hole is pressed against the bolt portion (refer to Patent Document 4). 
     However, not only in the double nut structure described above, but also in the structure described in Patent Document 4, a tool for fastening a fastening screw with a large torque and force for the fastening are required, and the fastening is a complicated operation using both hands. For example, in a cymbal holding structure for an upper cymbal in a high-hat stand, the cymbal is held using upper and lower bolts so as to be sandwiched between the bolts. The upper bolt serves as a screw for adjusting the cymbal fastening force, and the lower bolt serves as a screw for supporting the cymbal as well as used in detachment of the cymbal. However, these operations of adjustment of the cymbal fastening force and attachment/detachment of the cymbal are made to be complicated. 
     Further, since a cymbal is fastened by frictional pressure-contact force of a screw in all of these structures, it is not possible to reliably prevent the loosening of a fastener. Therefore, a performer cannot always play the cymbal without anxiety. In addition, a large torque is required for the fastening in order to prevent the loosening of a fastener. Therefore, a screw portion may be deformed while repeatedly using the structure, and the attachment operation may not be smoothly performed over time.

     Solution to Problem 
     In order to solve the aforementioned problems, the present invention has achieved a cymbal holding structure that comprises a cymbal supporting rod to be inserted into a center hole of a cymbal, the cymbal supporting rod including a bolt portion, and at least one elongated groove formed on the bolt portion, the at least one elongated groove extending across a spiral groove; and at least one fastener including a screw hole, a groove portion communicating with the screw hole, a locking claw slidingly guided in a radial direction along an inner surface of the groove portion so as to be protruded into and retracted from the screw hole, a biasing unit elastically biasing the locking claw so as to be protruded into the screw hole, and an operation unit operating the locking claw so as to be retracted from the screw hole against elastic biasing force of the biasing unit, wherein the at least one fastener is screwed with the bolt portion of the cymbal supporting rod to fasten the cymbal so as to be held on the cymbal supporting rod, and wherein the at least one fastener is brought into a loosening-prevented state in which the at least one fastener cannot rotate at least in a loosening direction by engagingly inserting the locking claw into the at least one elongated groove of the bolt portion, and the loosening-prevented state is released by operating the operation unit to retract the locking claw from the screw hole. 
     It is preferred that the operation unit comprise an operation member having a curved shape in plan view, the operation member including the locking claw integrally formed with an end thereof and continuously extending from the locking claw around the screw hole. 
     In particular, it is preferred that the operation member be formed to extend up to a position opposite to the locking claw with respect to an axial center or the vicinity thereof. 
     Further, it is preferred that the at least one fastener further include a cutout groove which is opened on an outer peripheral wall at a midway part in an axial direction thereof and communicates with the screw hole, and the operation member having the locking claw be slidably placed inside the cutout groove. 
     More specifically, it is preferred that the at least one fastener further include a pin which extends in the axial direction and is provided in a standing manner inside the cutout groove, and an operation member elongated groove formed on the operation member through which the pin passes and which also extends in parallel to a sliding direction of the locking claw, and a spring be housed, as the biasing unit, in the operation member elongated groove at a space on the opposite side of the locking claw with respect to the pin inside the operation member elongated groove, and the operation member be elastically biased by the spring so that the locking claw is protruded into the screw hole. 
     Further, it is preferred that the cymbal supporting rod be a hollow bolt to be attached to an up/down rod of a high-hat stand, the at least one elongated groove comprises two elongated grooves which are formed over respective two areas along the axial direction of the bolt portion, the at least one fastener comprises two fasteners which are positioned at the respective two areas in a loosening-prevented state in which locking claws of the fasteners are engagingly inserted into the elongated grooves, and the cymbal be held between the fasteners. 
     Further, the present invention also provides a cymbal stand including the cymbal holding structure described above. 
     In particular, it is preferred that the cymbal stand be a high-hat stand in which the cymbal supporting rod is a hollow bolt to be attached to an up/down rod of the high-hat stand. 
     Further, the present invention also provides a fastener used in the cymbal holding structure described above, the fastener comprising the screw hole, the groove portion, the locking claw, the biasing unit, and the operation unit. 
     Advantageous Effects of Invention 
     According to the cymbal holding structure of the present invention described above, the fastener is brought into a loosening-prevented state when the locking claw which is elastically biased so as to be protruded into the screw hole is engagingly inserted into the elongated groove of the bolt portion, and the loosening-prevented state is released by operating the operation unit to retract the locking claw from the screw hole. Therefore, operations of adjustment of the fastening force applied to the cymbal and attachment/detachment of the cymbal can be easily performed with one hand without using any tools only by operating the operation unit to rotate the fastener. Further, the loosening-prevented state is achieved by the engagement between the locking claw and the elongated hole. Therefore, fastening force for preventing the loosening is not required, no burden is caused on the cymbal supporting rod and the screw portion of the fastener, long product life cycles can be ensured, and smooth operability can be maintained for a long period of time. In addition, the loosening-prevented state is reliably and stably achieved by the engagement between the locking claw and the elongated hole, and a performer can therefore concentrate on his/her performance. 
     Further, the operation unit comprises an operation member having a curved shape in plan view, the operation member including the locking claw integrally formed with an end thereof and continuously extending from the locking claw around the screw hole. Therefore, the structure is made simple, the number of components can be reduced, and the durability can be made excellent. 
     Further, the operation member is formed to extend up to a position opposite to the locking claw with respect to an axial center or the vicinity thereof. Therefore, it is possible to efficiently operate the locking claw with minimum force passing through the axial center. 
     Further, the fastener includes a cutout groove which is opened on an outer peripheral wall at a midway part in an axial direction thereof and communicates with the screw hole. Furthermore, the operation member having the locking claw is slidably placed inside the cutout groove. Therefore, it is possible to achieve a smooth movement of the locking claw with a simple structure. 
     Further, the fastener includes a pin which extends in the axial direction and is provided in a standing manner inside the cutout groove, and an operation member elongated groove formed on the operation member through which the pin passes and which also extends in parallel to a sliding direction of the locking claw. Furthermore, a spring is housed, as the biasing unit, in the operation member elongated groove at a space on the opposite side of the locking claw with respect to the pin inside the operation member elongated groove. Moreover, the operation member is elastically biased by the spring so that the locking claw is protruded into the screw hole. Therefore, it is possible to achieve a structure for efficiently biasing the locking claw by the spring so as to be protruded in to the screw hole. 
     Further, the cymbal supporting rod is a hollow bolt to be attached to an up/down rod of a high-hat stand, the elongated grooves are formed over respective two areas along the axial direction of the bolt portion, the fasteners are positioned at the respective two areas in a loosening-prevented state in which locking claws of the fasteners are engagingly inserted into the elongated grooves, and the cymbal is held between the fasteners. Therefore, these fasteners can stably hold an upper cymbal in a high-hat stand which causes especially large vibration. In addition, the operation of adjustment of the fastening force applied to the cymbal by the upper fastener and the operation of attachment/detachment of the cymbal by the lower fastener can be easily performed with one hand without using any tools as described above. As a result, it is possible to provide an excellent high-hat stand capable of maintaining smooth operability for a long period of time.

     DESCRIPTION OF EMBODIMENTS 
     Next, an embodiment of the present invention will be described in detail with reference to the attached drawings. In the following embodiment, an example in which the cymbal holding structure of the present invention is applied to a holding structure for an upper cymbal in a high-hat stand will be described. However, the present invention is not limited to such a high-hat stand, and can also be applied to various cymbal stands such as a cymbal stand for holding a single cymbal or a cymbal holding structure such as an attachment. 
     As shown in  FIG. 1 , a high-hat stand H as an embodiment which has a cymbal holding structure S according to the present invention is provided with two foldable legs  84 , a pedal  83 , a lower pipe  80  which is provided in a standing manner by the legs  84  and the pedal  83 , an upper pipe  81  which is inserted into the upper part of the lower pipe  80  and supported by a thumbscrew  82  in a height-adjustable manner, an up/down rod  85  which is inserted into the upper pipe  81  and the lower pipe  80  so as to protrude from the bottom of the lower pipe  80  and connected to the pedal  83 , and moved up and down by a stepping-on operation of the pedal  83 , and a coil spring (not shown) which is stored inside the lower pipe  80  and biases the up/down rod  85  upward. Although the high-hat stand H is mainly made of a metallic material in the present embodiment, the present invention is not particularly limited thereto. 
     A cymbal receiver  86  is attached to the upper end part of the upper pipe  81 . A lower cymbal  70  is supported on the cymbal receiver  86 . A cymbal holder  1  is attached to an upper end part  85   a  of the up/down rod  85  which protrudes from the upper end of the upper pipe  81 . An upper cymbal  71  is held by the cymbal holder  1  in a position adjustable manner. By stepping on the pedal  83 , the up/down rod  85  is pulled down against the coil spring. The upper cymbal  71  is also moved downward integrally with the up/down rod  85 , and strikes the lower cymbal  70  supported on the cymbal receiver  86 . 
     A first support metal fitting  87  is attached to the outer peripheral wall of the lower pipe  80  at the midway part in the axial direction thereof by the fastening by the thumbscrew  91  so as to be slidable up and down. The upper ends of the legs  84  are connected to the support metal fitting  87  so as to be turnable up and down. A second support metal fitting  88  is attached to the outer peripheral wall of the lower pipe  80  at the lower part thereof. Each of stays  90  has one end which is connected to the middle part of each of the legs  84  so as to be turnable up and down and the other end which is connected to the support metal fitting  88  so as to be turnable up and down. When the thumbscrew  91  attached to the first support metal fitting  87  is loosened to thereby cause the first support metal fitting  87  to slide upward, the upper ends of the legs  84  and both of the ends of the stays  90  turn, so that each of the legs  84  changes its posture into a storage posture along the lower pipe  80 . 
     As shown in a cross-sectional view of  FIG. 2 , the cymbal receiver  86  which supports the lower cymbal  70  includes a tray member  92  which is fitted with the outer peripheral surface of an upper end part  81   a  of the upper pipe  81  and has a hole through which the up/down rod  85  is inserted on the center thereof, and a plate  93  and a felt  94  which are stacked on the top surface of the tray member  92  and also have holes through which the up/down rod  85  is inserted on the centers thereof. The tray member  92  includes a cylindrical portion  92   a  which is fitted with the upper end part  81   a  of the upper pipe  81  and a flange-shaped cymbal supporting portion  92   b  which is formed on the top of the cylindrical portion  92   a . The cymbal supporting portion  92   b  has a screw hole  92   c  near the outer periphery thereof, and a bolt  92   d  for adjusting the angle of the lower cymbal  70  is screwed with the screw hole  92   c.    
     The cymbal holder  1  constitutes the cymbal holding structure S according to the present invention as a main component. As shown in  FIG. 2  and  FIG. 3 , the cymbal holder  1  includes a hollow bolt  2  as a cymbal supporting rod which is inserted through a center hole  71   a  of the upper cymbal  71  and has a center hole  2   c  through which the up/down rod  85  is inserted so that the hollow bolt  2  is attached to the upper end part of the up/down rod  85 , a pair of upper and lower felt washers  4  which are externally attached to the hollow bolt  2  and hold the upper cymbal  71  therebetween, fasteners  3 A and  3 B which are respectively positioned on the top of the upper felt washer  4  and under the bottom of the lower felt washer  4  and screwed with the hollow bolt  2 , and a thumbscrew  5  which fixes the hollow bolt  2  to the up/down rod  85 . 
     The hollow bolt  2  includes a bolt portion  20 , the outer peripheral surface of which is threaded to form a male screw, and a cylindrical portion  21  which is integrally formed with the upper end of the bolt portion  20 . A screw hole  21   a  which communicates with the center hole  2   c  is formed on the outer peripheral surface of the cylindrical portion  21 . By screwing the thumbscrew  5  with the screw hole  21   a , the up/down rod  85  is pressed against the inner surface of the center hole  2   c  of the cylindrical portion  21 , and the hollow bolt  2  is thereby fixed to the up/down rod  85 . Although the cylindrical portion  21  is integrally formed with the hollow bolt  2  in the present embodiment, another configuration in which a separately prepared cylindrical member is attached to the upper end of a hollow bolt with a screw or the like is also preferred. 
     As shown in  FIGS. 4 to 6 , each of the fasteners  3 A and  3 B includes a main body  30  which has a screw hole  30   a  to be screwed with the bolt portion  20  of the hollow bolt  2  on the center thereof and a groove portion  31  which is opened on an outer peripheral wall  30   b  and communicates with the screw hole  30   a , a locking claw  32  which is slidingly guided in the radial direction along an inner surface  31   a  of the groove portion  31  so as to be protruded into and retracted from the screw hole  30   a , a spring  33  as biasing unit which elastically biases the locking claw  32  so as to be protruded into the screw hole  30   a , and an operation unit  34  which operates the locking claw  32  so as to be retracted from the screw hole  30   a  against the elastic biasing force of the biasing unit (the spring  33 ). 
     In the present embodiment, the locking claw  32  and the operation unit  34  are integrally formed with each other as operation member  60 . Specifically, the locking claw  32  is integrally formed with one end of the operation member  60 . The operation member  60  having a curved shape in plan view continuously extends from the locking claw  32  so as to form a generally C-shape around the screw hole  30   a , thereby forming the operation unit  34 . As the groove portion  31 , a cutout groove  61  which is opened on the outer peripheral wall  30   b  at the midway part in the axial direction thereof and communicates with the screw hole  30   a  is formed within the range of approximately 180° around the axial center of the main body  30 . The operation member  60  is slidably placed inside the cutout groove  61 . The inner surface  31   a  of the groove portion  31  is formed on the cutout groove  61  at a region corresponding to the position of the locking claw  32 . 
     In the present embodiment, since the operation member  60  is formed to extend up to a position that is opposite to the locking claw  32  with respect to the axial center of the main body  30  or the vicinity thereof, the cutout groove  61  is also formed within the range of approximately 180° so as to correspond to the shape of the operation member  60 . However, the operation member  60  may extend around the screw hole  30   a  in a shorter distance so as to be formed into an approximately J-shape, and the cutout groove  61  may also be formed within a narrower angle range so as to correspond to the shape of the operation member  60 . 
     A pin  62  which extends in the axial direction is provided in a standing manner inside the cutout groove  61 . An elongated groove  63  through which the pin  62  passes and which also extends in parallel to the sliding direction of the locking claw  32  is formed on the operation member  60 . The spring  33  is housed, as biasing unit, inside the elongated groove  63  at a space on the opposite side of the locking claw  32  with respect to the pin  62  inside the elongated groove  63 . Although the spring  33  is a coil spring in the present embodiment, other types of springs may also be used. Further, an elastic member such as rubber can also be used as the spring  33 . In the operation member  60 , the locking claw  32  is elastically biased by the spring  33  so as to be protruded into the screw hole  30   a.    
     More specifically, the elongated groove  63  includes an elongated hole  63   a  which penetrates the operation member  60  in the axial direction and receives the pin  62 , and a horizontal hole  63   b  which intersects the elongated hole  63   a  and extends in parallel to the sliding direction of the locking claw  32 . A bottomed concave portion  63   c  which communicates with the elongated hole  63   a  and houses the spring  33  therein is formed in the horizontal hole  63   b . Assembly in manufacturing these components can be easily performed by first inserting the spring  33  from an opening of the horizontal hole  63   b  on the opposite side of the concave portion  63   c , and then inserting the pin  62  through the elongated hole  63   a.    
     As shown in  FIG. 3  and  FIG. 6 , the bolt portion  20  of the hollow bolt  2  has elongated grooves  21 A and  21 B each of which extends across a spiral groove  20   a . The elongated grooves  21 A and  21 B are respectively formed over two areas R 1  and R 2  which extend along the axial direction. The fasteners  3 A and  3 B which are screwed with the bolt portion  20  are respectively positioned at the areas R 1  and R 2 . As a result, it is possible to achieve an unrotatable loosening-prevented state in which the locking claws  32  of the fastener  3 A and  3 B are engagingly inserted into the elongated grooves  21 A and  21 B, respectively. The upper cymbal  71  is stably held between the fasteners  3 A and  3 B in the loosening-prevented state with the felt washers  4  interposed therebetween. 
     Also in the respective areas R 1  and R 2 , the fasteners  3 A and  3 B can be rotated to move to any positions by pushing the operation units  34  to thereby retract the locking claws  32 . While the fastener  3 A ( 3 B) is caused to make a single rotation from the moved position with the operation unit  34  released, the locking claw  32  is engagingly inserted into the elongated groove  21 A ( 21 B). As a result, the fastener  3 A ( 3 B) can be brought into the unrotatable loosening-prevented state. In the present embodiment, when the locking claw  32  is engagingly inserted into the elongated groove  21 A ( 21 B), the fastener  3 A ( 3 B) cannot rotate in both of the loosening direction and the fastening direction unless the operation unit  34  is operated. However, for example, it is also preferred that only a side surface of the locking claw  32 , the side surface being positioned in the fastening direction, be formed into a tapered surface. In such a configuration, the fastener  3 A ( 3 B) with the locking claw  32  engagingly inserted into the elongated groove  21 A ( 21 B) cannot rotate in the loosening direction without operating the operation unit  34 . However, the fastener  3 A ( 3 B) can rotate in the fastening direction because the tapered surface is pushed by the edge of the elongated groove  21 A ( 21 B), and the locking claw  32  thereby automatically retracts from the screw hole  30   a . In this case, the operation unit should be operated only when rotating the fastener  3 A ( 3 B) in the loosening direction. Therefore, the operability is improved. 
     Each of the elongated grooves  21 A and  21 B is a vertical groove which extends in the axial direction in the present embodiment. However, each of the elongated grooves  21 A and  21 B may be oblique groove or curved groove. Further, each of the elongated grooves  21 A and  21 B is formed around the bolt portion  20  at a single location, and the locking claw  32  is engagingly inserted thereinto only once by every single rotation of the fastener  3 A ( 3 B) in the present embodiment. However, it is also preferred that a plurality of elongated grooves  21 A ( 21 B) be formed so that the locking claw  32  can be engagingly inserted thereinto multiple times by every single rotation of the fastener  3 A ( 3 B), thereby making it possible to perform finer position adjustment and fastening force adjustment for the upper cymbal  71 . In this case, the elongated grooves  21 A ( 21 B) may be formed throughout the area R 1  (R 2 ). Alternatively, excepting a first one of the elongated grooves  21 A ( 21 B), elongated grooves having a relatively short length may be supplementarily formed only within a particular area in the area R 1  (R 2 ) in which fine adjustment is desirably performed. 
     In the cymbal holding structure S in the present embodiment, each of the fasteners  3 A and  3 B which fasten the upper cymbal  71  from top and bottom is provided with the screw hole  30   a , the groove portion  31 , the locking claw  32 , the spring  33  as biasing unit, and the operation unit  34 . However, only one of the fasteners  3 A and  3 B may have the above configuration, and the other one may be a conventional fastener such as a double nut. For example, even when the fastener of the present embodiment is applied only to the lower fastener  3 B, it is possible to easily detach the upper cymbal only with hands after a performance, and also easily and reliably attach the upper cymbal with one hand in a loosening-prevented state. Therefore, such a configuration is also preferred. 
     Further, also when the fastener of the present embodiment is applied only to the upper fastener  3 A, the upper fastener  3 A which is used to adjust the fastening force applied to a cymbal by a performer can be easily rotated only with hands without using any tools to thereby adjust the fastening force and bring the fastener  3 A into a loosening-prevented state. Therefore, such a configuration is also preferred. Similarly, although a description has been made with regard to the holding structure for an upper cymbal in a high-hat stand in the present embodiment, the present invention can also be applied to other cymbal stands and cymbal attachments as described above. When using only one fastener for fastening a cymbal having a screw hole in these cymbal stands and cymbal attachments, by using the fastener  3 A of the present embodiment, it is possible to easily rotate the fastener  3 A only with hands without using any tools to thereby adjust the fastening force applied to the cymbal and bring the fastener  3 A into a loosening-prevented state in the same manner as above. 
     While the embodiment of the present invention has been described, the present invention is not limited to the described embodiment. It should therefore be understood that the present invention can be embodied in various forms without departing from the scope of the invention.
