The present invention relates to a cymbal holder that holds a cymbal to a cymbal stand and a cymbal stand having a cymbal holder.
A cymbal stand has a stand body and a cymbal holder that holds cymbal at an upper end of the stand body. Japanese Utility Model No. 3069348 discloses a cymbal holder. The cymbal holder disclosed in the publication has a support member, a retainer and a nut. The support member is attached to an upper end of the stand body. The retainer is attached to a bolt of the support member. The nut is screwed to the bolt. In this cymbal holder, when the cymbal is attached to and detached from the stand body, it is necessary that the nut that is screwed to the bolt be tightened and loosened. In order to facilitate the attachment and detachment of the nut, the following configurations have been proposed.
U.S. Pat. No. 4,960,028 discloses a cymbal holder having a pair of sleeve members that are engaged with a bolt and a coil spring that urges the sleeve members. U.S. Pat. No. 5,785,480 discloses a cymbal holder having a holder body, a nut member and a compression coil spring. The nut member has a nut and an operation button that are integrally formed. The compression coil spring urges the nut member. U.S. Pat. No. 6,884,015 discloses a holder for percussive instruments having a holder body and a pair of rotation members. The holder body has a lock opening and the rotation members are attached to the holder body. In the holder for percussive instruments, an inner peripheral surface of the lock opening is deformed by a cam surface of each rotation member so as to approach an axial line of the lock opening. Accordingly, a screw on the inner peripheral surface of the lock opening is engaged with a screw on the outer surface, and the holder for percussive instruments are attached to the bolt.
However, in the cymbal holder disclosed in U.S. Pat. No. 4,960,028, when the cymbal is struck and shaken, the sleeve member is shaken with the cymbal and removed from the bolt. Accordingly, the cymbal holder can no longer hold the cymbal to the cymbal stand. Only one nut member for engaging the cymbal holder to the bolt is provided in the cymbal holder disclosed in U.S. Pat. No. 5,785,480. Therefore, if a stick contacts a button during a musical performance, the nut member is disengaged from the bolt and the cymbal can no longer be held to the cymbal stand. As in the case of U.S. Pat. No. 4,960,028, when the cymbal is struck and shaken, the cymbal holder is shaken with the cymbal and may come off the bolt. Further, the nut member needs to be made of metal to ensure fastening strength with respect to the bolt. This increases the costs for the members, and the cymbal holder cannot be manufactured with low cost. According to the holder for percussive instruments disclosed in U.S. Pat. No. 6,884,015, it is necessary that the rotation member be locked to the holder body. This makes it troublesome to attach and detach the holder to and from the bolt. Even if the bolt is not properly engaged with the screw portion of the lock opening, the rotation member is forcibly rotated to be locked to the holder body. Accordingly, the screw portion of the lock opening may be damaged and the life of product is shortened.
An objective of the present invention is to provide a cymbal holder that reliably holds a cymbal to a cymbal stand and a cymbal stand having the cymbal holder.
To achieve the foregoing objective and in accordance with a first aspect of the present invention, a cymbal holder for holding a cymbal by tightening up the cymbal between a retainer supporting the cymbal and the cymbal holder is provided. The cymbal holder is screwed to and tightened up to a bolt projected from an upper end of the retainer so as to hold the cymbal. The cymbal holder includes a holder body, a first operation button and a second operation button, a first split nut and a second split nut, and urging means. The holder body has an insertion opening through which the bolt is inserted. The first operation button and the second operation button are provided to the holder body and operated for attachment and detachment of the cymbal. The first split nut and the second split nut are movably supported in the holder body and engaged with the bolt. The urging means urges at least one of the split nuts. The split nuts are caused to approach each other by urging force of the urging means so as to be engaged with the bolt, and the split nuts are separated from each other by operation of the operation buttons so as to be disengaged from the bolt.
In accordance with a second aspect of the present invention, a cymbal stand including a stand body having a bolt at its distal end and a cymbal holder for holding a cymbal at an upper end of the stand body is provided. The cymbal is held at the stand body by tightening up the cymbal holder that is screwed to the bolt. The cymbal holder includes a holder body, a first operation button and a second operation button, a first split nut and a second split nut, and urging means. The holder body has an insertion opening through which the bolt is inserted. The first operation button and the second operation button are provided on the holder body and operated for attachment and detachment of the cymbal. The first split nut and the second split nut are movably supported in the holder body and engaged with the bolt. The urging means urges at least one of the split nuts. The split nuts are caused to approach each other by urging force of the urging means so as to be engaged with the bolt, and the split nuts are separated from each other by operation of the operation buttons so as to be disengaged from the bolt.

The communication opening 18 is formed as an elongated opening having a cross section of the same shape as the opening of the rectangular tube portion 14.
According to the present embodiment, the first engagement member 20a includes a first split nut and a first operation button that are integrally formed. The first engagement member 20a has the first split nut as a first nut portion 21a, and the first operation button as a first button portion 22a. The second engagement member 20b includes a second split nut and a second operation button that are integrally formed. The second engagement member 20b has the second split nut as a second nut portion 21b, and the second operation button as a second button portion 22b. The first and second engagement members 20a, 20b have the same shape and size.
The first nut portion 21a has a screw on a surface facing the first button portion 22a. The screw is engaged with the bolt 5. The first nut portion 21a has a first accommodation hole 23a for accommodating a first compression coil spring 40a on a surface opposite to the first button portion 22a. A first fitting opening 24a for engagement with the ring 50 is provided on an upper surface and a lower surface of the first nut portion 21a. The first button portion 22a has a first support recess 25a on a surface facing the first nut portion 21a. The first support recess 25a supports an end portion of a second compression coil spring 40b.
Similarly, the second nut portion 21b has a screw on a surface facing the second button portion 22b. The screw is engaged with the bolt 5. The second nut portion 21b has a second accommodation opening 23b on a surface opposite to the second button portion 22b. The second accommodation opening 23b accommodates a second compression coil spring 40b. A second fitting opening 24b for the engagement with the ring 50 is provided on an upper surface and a lower surface of the second nut portion 21b. The second button portion 22b has a second support recess 25b on a surface facing the second nut portion 21b. The second support recess 25b supports an end portion of the second compression coil spring 40b. Each screw of the first and second nut portions 21a, 21b is a split screw that is formed by separating a female screw along its axial line.
A pair of first frames 28a are provided between the first nut portion 21a and the first button portion 22a so as to connect them to each other. The first engagement member 20a has a first accommodation space 29a that is surrounded by the first nut portion 21a, the first button portion 22a, and the pair of first frames 28a. Similarly, a pair of second frames 28b are provided between the second nut portion 21b and the second button portion 22b so as to connect them to each other. The second engagement member 20b has a second accommodation space 29b that is surrounded by the second nut portion 21b, the second button portion 22b, and the pair of second frames 28b. The second nut portion 21b and the second compression coil spring 40b are accommodated in the first accommodation space 29a of the first engagement member 20a. The first nut portion 21a and the first compression coil spring 40a are accommodated in the second accommodation space 29b of the second engagement member 20b.
As shown in
The first and second compression coil springs 40a, 40b urge the first and second engagement members 20a, 20b toward each other, that is, in a direction for engaging the nut portions 21a, 21b with the bolt 5. On the other hand, when the first and second button portions 22a, 22b are pressed against the urging force of the first and second compression coil springs 40a, 40b, the first and second engagement members 20a, 20b slide such that the first and second nut portions 21a, 21b are separated from each other. Accordingly, the first and second nut portions 21a, 21b are separated such that the space 26 between the first nut portion 21a and the second nut portion 21b becomes greater than the diameter of the bolt 5 that is engaged with the nut portions 21a, 21b.
The first and second engagement members 20a, 20b are accommodated in the communication opening 18 of the holder body 11 in a state where the first and second engagement members 20a, 20b are assembled as described above. The first and second engagement members 20a, 20b are arranged such that the space 26 between the first nut portion 21a and the second nut portion 21b coincides with the insertion hole 13. The ring 50 is mounted in the groove 17 formed on the holder body 11. A pair of hooks 51 are provided on the inner peripheral surface of the ring 50. The hooks 51 are arranged symmetrically with respect to the axial line of the ring 50. Each of the hooks 51 is engaged with each of the fitting openings 24a, 24b of the first and second nut portions 21a, 21b. Accordingly, the first and second engagement members 20a, 20b are attached to a predetermined position in the holder body 11 and held in the holder body 11 so as not to come off from the holder body 11.
Next, a using method of the cymbal holder 10 will be explained with reference to
As shown in
Next, as shown in
The bolt 5 is inserted through the insertion hole 13 of the holder body 11 while the first and second button portions 22a, 22b are pressed, and the first and second button portions 22a, 22b are released from the pressed state when the bolt 5 is in a proper position. This engages the first and second nut portions 21a, 21b with the bolt 5, and the cymbal holder 10 is screwed to the bolt 5. At this time, as shown in
Next, the player tightens up the cymbal holder 10, which is screwed to the bolt 5, as shown in
On the other hand, as shown in
When the above-described process is carried out in a reverse order, the cymbal 4 is removed from the stand body 2. Specifically, the first and second button portions 22a, 22b of the cymbal holder 10 that is tightened up to the bolt 5 are pinched by fingers to be pressed. This disengages the first and second nut portions 21a, 21b from the bolt 5. The cymbal holder 10 is pulled out from and removed from the bolt 5 in a state while the first and second button portions 22a, 22b are pressed. After the cymbal holder 10 is removed from the bolt 5, the cymbal 4 is removed from the stand body 2 with the shock absorbing member 7.
According to the present embodiment, the following advantages are obtained.
(1) The cymbal holder 10 has the holder body 11 having the insertion hole 13, the first and second engagement members 20a, 20b, and the first and second compression coil springs 40a, 40b. The first engagement member 20a has the first split nut as the first nut portion 21a and has the first operation button as the first button portion 22a. The second engagement member 20b has the second split nut as the second nut portion 21b and has the second operation button as the second button portion 22b.
According to this configuration, the bolt 5 is inserted through the insertion hole 13 of the holder body 11, and the nut portions 21a, 21b approach each other by the urging force of the first and second compression coil springs 40a, 40b to be engaged with the bolt 5 in the holder body 11. Therefore, when the cymbal 4 is struck and shaken, the nut portions 21a and 21b are prevented from opening and coming off the bolt 5. The nut portions 21a, 21b are separated from each other by the depression of the button portions 22a, 22b to release the engagement of the nut portions 21a, 21b and the bolt 5. Therefore, even if a stick contacts one of the button portions during the musical performance, the nut portions 21a, 21b are not removed from the bolt 5 as long as both button portions 22a, 22b are not depressed. Accordingly, the cymbal holder 10 is not easily removed from the bolt 5, and the cymbal 4 is reliably held by the cymbal stand 1.
(2) The inner diameter of the insertion hole 13 is set to be 1 to 11/10 times the outer diameter of the bolt 5. Accordingly, the clearance between the inner surface of the insertion hole 13 and the bolt 5 is set to be as small as possible within a range that allows the insertion of the bolt 5. Therefore, when the cymbal 4 is struck and shaken, the rattling of the cymbal holder 10 is suppressed. This effectively prevents that the nut portions 21a, 21b from being separated from each other and being removed from the bolt 5.
(3) The first and second nut portions 21a, 21b are engaged with the bolt 5 without causing the split surfaces 27a, 27b of the nut portions 21a, 21b to contact each other. According to this configuration, the engagement of each of the first and second nut portions 21a, 21b with the bolt 5 is not restricted by the other nut portion. This increases the engagement force between the nut portions 21a, 21b and the bolt 5 and improves the fastening strength of the nut portions 21a, 21b with respect to the bolt 5. Therefore, if the cymbal 4 is rotated around the bolt 5 during the musical performance, the cymbal holder 10 is not rotated with the cymbal 4. Therefore, the cymbal holder 10 is held so as not to be loosened from the state where the cymbal holder 10 is tightened up to the bolt 5.
(4) The cylindrical projection portion 15 is formed on the lower surface 12b of the cylindrical portion 12. The bolt 5 is inserted through the projection portion 15. According to this configuration, the cymbal holder 10 is tightened up in a state where the bolt is inserted through the cylindrical projection portion 15. Since the outer peripheral surface of the bolt 5 is covered by the projection portion 15 in this state, the inner peripheral surface of the attachment opening of the cymbal 4 does not slide with the outer peripheral surface of the bolt 5 when the cymbal 4 is struck and shaken. Therefore, the inner peripheral surface of the attachment opening of the cymbal 4 is not ground by the thread of the bolt 5.
(5) When the cymbal holder 10 is tightened up with the lower surface 12b of the cylindrical portion 12 having the projection portion 15 facing downward, the distal end of the projection portion 15 contacts the upper end of the retainer 6 and the tightening amount of the cymbal holder 10 with respect to the bolt 5 is restricted. On the other hand, when the cymbal holder 10 is tightened up with the upper surface 12a of the cylindrical portion 12 having no projection portion 15 facing downward, the cymbal holder 10 is tightened up until the upper surface 12a of the cylindrical portion 12 contacts the upper end of the retainer 6. Accordingly, the player selectively tightens up the cymbal holder 10 up-side-down so as to select the tightening pressure of the cymbal 4 and select one of two different sounds of the cymbal. According to this configuration, the projection portion 15, which protects the attachment opening of the cymbal 4, is used for selecting the tightening pressure of the cymbal 4. Therefore, no additional part is required. This achieves the cymbal holder 10 that allows the tightening pressure of the cymbal 4 to be selected without increasing the number of parts.
(6) The first engagement member 20a is formed by integrating the first split nut and the first operation button, and the second engagement member 20b is formed by integrating the second split nut and the second operation button. This configuration further reduces the number of parts of the cymbal holder 10. This reduces the manufacturing costs.
(7) The first and second engagement members 20a, 20b have the same shape and size. According to this configuration, the same mold can be used for molding the first and second engagement members 20a, 20b, and the first and second engagement members 20a, 20b are not assembled to each other by mistake.
(8) The cymbal holder 10 has the ring 50 as the retaining member. According to this configuration, the ring 50 holds the engagement members 20a, 20b so as not to come off from the holder body 11.
(9) The holder body 11, the first and second engagement members 20a, 20b, and the ring 50 are each made of a resin material. According to this configuration, most of the parts forming the cymbal holder 10 are made of resin. This reduces the weight of the cymbal holder 10 and the manufacturing costs.
(10) The cymbal stand 1 has the stand body 2 including a tripod, the tilter 3 and the cymbal holder 10. According to this configuration, the cymbal stand 1 having the above-described advantages is provided.
The present embodiment may be modified as follows.
In the present embodiment, the first and second nut portions 21a, 21b may be engaged with the bolt 5 while causing the split surfaces 27a, 27b of the nut portions 21a, 21b to contact each other.
In the present embodiment, the projection portion 15 may be provided on the upper surface 12a and the lower surface 12b of the cylindrical portion 12. In this case, the height of the projection portion 15 provided on each of the upper surface 12a and the lower surface 12b may be different. In this case, by tightening up the cymbal holder up-side-down, the tightening pressure of the cymbal is selected to select the sound of the cymbal.
The projection portion 15 may be omitted from the cylindrical portion 12 of the holder body 11. In this case, regardless of the attachment direction in which the cymbal holder 10 is tightened, the cymbal holder 10 is tightened until the upper surface 12a of the cylindrical portion 12 contacts the upper end of the retainer 6.
In the present embodiment, the first and second compression coil springs 40a, 40b are provided as the urging means. However, like a cymbal holder 80 shown in
In the present embodiment, a groove 17 for receiving the ring 50 may be provided on the upper surface 12a of the cylindrical portion 12, or may be provided on the upper surface 12a and the lower surface 12b of the cylindrical portion 12.
In the present embodiment, the holder body 11, the first and second engagement members 20a, 20b and the ring 50 may be made of a material other than a resin material, for example, wood or ceramics, as necessary.
In the present embodiment, in place of the first and second engagement members 20a, 20b, the first split nut and the first operation button may be formed separately and the second split nut and the second operation button may be formed separately. For example, in a cymbal holder 90 shown in
In the present embodiment, the cymbal holder 10 is embodied to hold the cymbal 4 to the cymbal stand. However, the cymbal holder 10 may be embodied to hold the cymbal 4 to a cymbal rack or a cymbal attachment.
