PROBLEM TO BE SOLVED: To provide a drum stand capable of generating original sound of a drum by sufficiently suppressing transmission of drum vibration to the floor and capable of adjusting height while avoiding an increase in weight and enlargement of a device by suppressing an increase in the number of components and cost-up in a simple structure, and also to provide a drum device equipped with the same.SOLUTION: A drum stand includes: right and left support parts 2 by which a drum D is supported from right and left sides so at to be rotatable and changeable in height; and right and left elasticity giving parts 3 which are continuously provided in the lower parts of the respective support parts 2 and have bent parts 30 and 31 bent in the direction orthogonal to the direction of a rotational axis of the drum rotated by the support parts 2.SELECTED DRAWING: Figure 1

Description

本発明は、ドラムを左右側方から回動可能に支持するドラムスタンド及びこれを備えるドラム装置に関する。   The present invention relates to a drum stand that rotatably supports a drum from the left and right sides, and a drum device including the drum stand.

この種のドラムスタンドとしては、従来から、床面に立設された支柱と、ドラム中心軸を含む平面に対して直交する方向に延びて、この支柱に支持された回転軸とを備え、ドラムをこの回転軸の回りに回転自在に支持するドラムスタンドが提供されている（例えば、特許文献１参照。）。しかし、このようなドラムスタンドはドラムの響きがスタンド、床に伝わり、ドラム本来の音が出ないという課題があった。   Conventionally, this type of drum stand includes a support column erected on the floor surface and a rotation shaft that extends in a direction orthogonal to a plane including the drum central axis and is supported by the support column. There is provided a drum stand that rotatably supports a rotating shaft around the rotation axis (see, for example, Patent Document 1). However, such a drum stand has a problem that the sound of the drum is transmitted to the stand and the floor, and the original sound of the drum does not come out.

また、このような課題を解消するものとして、ドラムの周囲を囲むようにリング部材を配置し、このリング部材を一対の支柱に回転自在に支持させ、該リング部材に弾性保持具を介してドラム胴を支持させ、ドラムを浮いた状態に保持するドラムスタンドも提案されている（例えば、特許文献２、３参照）。   Further, in order to solve such a problem, a ring member is disposed so as to surround the drum, and the ring member is rotatably supported by a pair of support columns. A drum stand that supports the drum and holds the drum in a floating state has also been proposed (see, for example, Patent Documents 2 and 3).

しかし、このようなドラムとリング部材との間の弾性保持具によって振動の伝わりを遮断するのは限界があり、リング部材や支柱を通じて床に振動が伝達してしまうという課題がある。また、このようなリング部材や弾性保持具は部品点数の増加、コストアップの原因となり、重量アップにも繋がる。また、ドラム胴の周りにドラムより大径のリング部材が存在すると、これを支持する左右の支柱の間隔も大きくなり、装置全体が大型化し、空間占有率が大きくなり効率が悪く、また演奏時に邪魔になる可能性もある。   However, there is a limit to interrupting the transmission of vibration by such an elastic holder between the drum and the ring member, and there is a problem that the vibration is transmitted to the floor through the ring member or the column. Moreover, such a ring member or elastic holder causes an increase in the number of parts and an increase in cost, leading to an increase in weight. Also, if there is a ring member with a diameter larger than that of the drum around the drum body, the distance between the left and right struts supporting the drum member also increases, the overall apparatus becomes larger, the space occupancy rate increases, the efficiency becomes lower, and It may get in the way.

また、従来、ドラムを高さ変更可能に支持するドラムスタンドが存在しなかった。これは、例えば特許文献１のドラムスタンドでは、ドラムを確りと支持するために設計される当該スタンドに高さ調節の機能を付与することまでは考慮されておらず、また特許文献２、３のドラムスタンドではリング部材やこれを支持する支柱の構造が特殊な構造であり、同じく高さ調節の機能を付与することは考慮されていない。   Conventionally, there has been no drum stand that supports the drum so that the height can be changed. This is not considered, for example, in the case of the drum stand of Patent Document 1 until the height adjustment function is given to the stand designed to firmly support the drum. In the drum stand, the structure of the ring member and the supporting column that supports the ring member is a special structure, and it is not considered that the function of adjusting the height is given.

そこで、本発明が前述の状況に鑑み、解決しようとするところは、シンプルな構造で部品点数の増加やコストアップを抑え、重量アップや装置の大型化も回避しつつ、ドラム振動の床への伝達を十分に抑え、ドラム本来の音を出すことができ、且つ高さ調節もできるドラムスタンド及びこれを備えるドラム装置を提供する点にある。   Therefore, in view of the above-described situation, the present invention intends to solve the problem that a simple structure suppresses an increase in the number of parts and costs, and avoids an increase in weight and an increase in the size of the apparatus, while avoiding an increase in the size of the apparatus. The object of the present invention is to provide a drum stand that can sufficiently suppress transmission, produce the original sound of a drum, and can be adjusted in height, and a drum device including the drum stand.

本発明は、前述の課題解決のために、ドラムを左右側方から回動可能且つ高さ変更可能に支持する左右の支持部と、各支持部の下方に連続して設けられ、前記回動軸の方向に直交する方向に屈曲した単又は複数の屈曲部を有する左右の弾性付与部とを備えてなることを特徴とするドラムスタンドを提供する。   In order to solve the above-mentioned problems, the present invention is provided with left and right support portions that support the drum so that the drum can be rotated from the left and right sides and the height can be changed, and the support portions are continuously provided below the support portions. There is provided a drum stand comprising: left and right elasticity applying portions having one or a plurality of bent portions bent in a direction perpendicular to the axis direction.

ここで、前記支持部を、ドラムを左右側方から回動角変更可能に支承する角度調節機構と、高さ方向に長く構成され、前記角度調節機構を高さ位置変更可能に支持する支持部材とより構成したものが好ましい。   Here, an angle adjustment mechanism that supports the support portion so that the rotation angle of the drum can be changed from the left and right sides, and a support member that is long in the height direction and supports the angle adjustment mechanism so that the height position can be changed. And more preferably.

特に、前記支持部材の上側の領域を、前記角度調節機構を高さ位置変更可能に支持する支持領域とし、これに連続する下側の領域に、前記回動軸の方向に直交する方向に屈曲した単又は複数の屈曲部を有する前記弾性付与部を設けたものが好ましい。   In particular, the upper region of the support member is a support region that supports the angle adjustment mechanism so that the height position can be changed, and the lower region that is continuous to the support region is bent in a direction perpendicular to the direction of the rotation axis. What provided the said elasticity provision part which has a single or several bending part was preferable.

また、前記支持部材の前記弾性付与部より下側の領域に、さらに前後水平に延びる基台部を設けたものが好ましい。   Moreover, what provided the base part further extended in the front-back horizontal in the area | region below the said elasticity provision part of the said support member is preferable.

さらに、前記支持部と弾性付与部と基台部とを左右独立した前記長尺部材によりそれぞれ構成するとともに、左右の基台部の間に単又は複数の連結部材を渡設し、これら左右の基台部及び連結部材により基台を構成したものが好ましい。   Furthermore, the support part, the elasticity applying part, and the base part are respectively configured by the left and right independent long members, and a single or a plurality of connecting members are provided between the left and right base parts. What comprised the base with the base part and the connection member is preferable.

また、前記角度調節機構が、ドラムを回動可能に支承する支承部と、前記支持部材に高さ位置変更可能に固定される固定部とよりなるものが好ましい。   In addition, it is preferable that the angle adjusting mechanism includes a support portion that rotatably supports the drum and a fixing portion that is fixed to the support member so that the height position can be changed.

特に、前記支承部を前記固定部よりも上方の位置に設けたものが好ましい。   In particular, it is preferable that the support portion is provided at a position above the fixed portion.

また本発明は、ドラムと、上記したドラムスタンドとよりなるドラム装置をも提供する。   The present invention also provides a drum device including a drum and the drum stand described above.

以上にしてなる本願発明に係るドラムスタンド及びこれを備えるドラム装置によれば、上側の支持部でドラムを回動可能且つ高さ調節も支持しつつ、下側の限られた部位に、各支持部に連続して設けられ、回動軸の方向に直交する方向に屈曲した単又は複数の屈曲部を有する左右の弾性付与部を設けることで、当該屈曲部を備えたシンプルな構造によってドラム振動の床への伝達を効率良く抑えることができ、部品点数の増加やコストアップを抑え、重量アップや装置の大型化も回避しつつ、ドラム振動の床への伝達を十分に抑え、ドラム本来の音を出すことができる。   According to the drum stand and the drum apparatus including the drum stand according to the present invention as described above, the upper support portion can rotate the drum and also supports the height adjustment, while supporting each of the lower limited portions. By providing a left and right elasticity applying portion having one or a plurality of bent portions that are continuously provided in the portion and bent in a direction perpendicular to the direction of the rotation axis, drum vibration is achieved by a simple structure including the bent portion. The transmission of drum vibration to the floor can be efficiently suppressed, the increase in the number of parts and cost is suppressed, the weight vibration and the increase in the size of the device are avoided, and the transmission of drum vibration to the floor is sufficiently suppressed. Can make sound.

また弾性付与部は、上記のとおり単又は複数の屈曲部で構成され、上下の幅を抑えつつ長さを維持し、効率よくドラム振動の床への伝達を抑えることができるので、上側の支持部として高さ調節に必要な上下の幅を十分確保することができ、このように振動伝達の抑制の機能と高さ調節の機能を合せ持ちつつ、トータルの高さを抑えることができ、例えばドラムを下に下げても左右から上方に突出せず、演奏の邪魔にならないように構成することができる。   In addition, as described above, the elasticity imparting portion is composed of a single or a plurality of bent portions, maintains the length while suppressing the vertical width, and can efficiently suppress the transmission of the drum vibration to the floor. As a part, it is possible to sufficiently secure the vertical width necessary for height adjustment, and thus the total height can be suppressed while having both the function of suppressing vibration transmission and the function of height adjustment, for example, Even if the drum is lowered, the drum does not protrude upward from the left and right, so that it does not interfere with the performance.

また、前記支持部を、ドラムを左右側方から回動角変更可能に支承する角度調節機構と、高さ方向に長く構成され、前記角度調節機構を高さ位置変更可能に支持する支持部材とより構成したので、当該支持部によりドラムの回動角を変更してドラム打面の角度を調節したり、当該角度調節機構の支持部材に対する取り付け高さを変更することで高さ調節をすることが可能となる。   An angle adjustment mechanism that supports the support portion so that the rotation angle of the drum can be changed from the left and right sides; a support member that is configured to be long in the height direction and supports the angle adjustment mechanism so that the height position can be changed; Since the support portion is configured to change the rotation angle of the drum to adjust the angle of the drum striking surface, or to adjust the height by changing the mounting height of the angle adjustment mechanism with respect to the support member. Is possible.

また、前記支持部材の上側の領域を、前記角度調節機構を高さ位置変更可能に支持する支持領域とし、これに連続する下側の領域に、前記回動軸の方向に直交する方向に屈曲した単又は複数の屈曲部を有する前記弾性付与部を設けたので、一部材で高さ調節の機能と弾性付与部との双方を兼ね備えさせることができ、効率化によるコスト低減、軽量化が可能となる。   Further, the upper region of the support member is a support region that supports the angle adjustment mechanism so that the height position can be changed, and the lower region continuous thereto is bent in a direction perpendicular to the direction of the rotation shaft. Since the above-mentioned elasticity imparting part having one or a plurality of bent parts is provided, it is possible to combine both the height adjusting function and the elasticity imparting part with a single member, and it is possible to reduce cost and weight by increasing efficiency. It becomes.

また、支持部材の弾性付与部より下側の領域に、さらに前後水平に延びる基台部を設けたので、同じく一部材で基台部も設けることができ、効率がよくコスト低減を図ることができ、軽量化も可能となる。   In addition, since the base portion extending further in the front-rear and horizontal directions is provided in the region below the elasticity imparting portion of the support member, the base portion can also be provided with the same member, and the efficiency can be reduced and the cost can be reduced. Can be reduced in weight.

また、支持部材を、中空又は中実の長尺部材より構成したので、低コスト化、軽量化が可能であり、屈曲部を有する弾性付与部も効率よく形成することができる。   In addition, since the support member is composed of a hollow or solid long member, the cost can be reduced and the weight can be reduced, and the elasticity applying portion having a bent portion can be formed efficiently.

また、支持部と弾性付与部と基台部とを左右独立した前記長尺部材によりそれぞれ構成するとともに、左右の基台部の間に単又は複数の連結部材を渡設し、これら左右の基台部及び連結部材により基台を構成したので、このような左右独立の長尺部材は左右一体型に比べて屈曲部の曲げ加工を一平面上で終えることができ、加工コストが低減でき、トータルのコストも低減できるとともに、連結部材により基台を安定化させることも容易となる。   In addition, the support portion, the elasticity applying portion, and the base portion are each constituted by the long and independent independent members, and one or a plurality of connecting members are provided between the left and right base portions, Since the base is composed of the base part and the connecting member, such a left and right independent long member can finish the bending process of the bent part on one plane as compared with the left and right integrated type, and the processing cost can be reduced. The total cost can be reduced and the base can be stabilized by the connecting member.

また、前記角度調節機構が、ドラムを回動可能に支承する支承部と、前記支持部材に高さ位置変更可能に固定される固定部とよりなるので、角度の調節と高さの調節を角度調節機構の支承部、固定部を動作させることで実現できる。   In addition, the angle adjustment mechanism includes a support portion that rotatably supports the drum and a fixed portion that is fixed to the support member so that the height position can be changed. This can be realized by operating the support part and the fixed part of the adjustment mechanism.

また、前記支承部を前記固定部よりも上方の位置に設けてなるので、高さ調節の際に上下に移動する固定部よりも上方の位置でドラムを回動可能に支持することとなり、高さ調節の範囲を維持しつつ、ドラムの高さを下方に下げても支持部材がドラムより上に突出して演奏の邪魔にならないように設定することが容易となり、言い換えれば、長すぎない支持部材を用いつつ十分に高い位置までドラムを調節することが可能となる。   In addition, since the support portion is provided at a position above the fixed portion, the drum is rotatably supported at a position above the fixed portion that moves up and down during height adjustment. It is easy to set the support member so that it does not interfere with performance even if the height of the drum is lowered while maintaining the range of height adjustment, in other words, the support member is not too long. It is possible to adjust the drum to a sufficiently high position while using.

次に、本発明の実施形態を添付図面に基づき詳細に説明する。   Next, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

本発明に係るドラム装置Ｓは、図１及び図２に示すように、ドラムＤと、これをドラム打面の角度及び高さが調節可能となるように支持するドラムスタンド１とより構成されている。特にドラムスタンド１は、ドラムＤを左右側方から回動可能且つ高さ変更可能に支持する左右の支持部２と、各支持部２の下方に連続して設けられ、回動軸、すなわち支持部２により回動されるドラムの回動軸の方向に対して直交する方向に屈曲した屈曲部３０、３１を有する左右の弾性付与部３とを備えている。   As shown in FIGS. 1 and 2, the drum device S according to the present invention includes a drum D and a drum stand 1 that supports the drum D so that the angle and height of the drum striking surface can be adjusted. Yes. In particular, the drum stand 1 is provided continuously to the left and right support portions 2 that support the drum D so that the drum D can be rotated from the left and right sides and the height can be changed, and below the support portions 2. And left and right elasticity applying portions 3 having bent portions 30 and 31 bent in a direction orthogonal to the direction of the rotation axis of the drum rotated by the portion 2.

弾性付与部３は、ドラムＤの演奏時の振動を床へ伝達されることを抑制し、ドラム本来の自然な鳴りを発揮しうるように作用する。尚、以下の説明では、ドラムＤをコンサートバスドラムとした例について説明するが、本発明はこれに何ら限定されず、和太鼓やドラムセットを構成する各種バスドラム、スネアドラム、タムタム等、また例えばマルチタムなど、複数のドラムを連結した連結体であってもよい。   The elasticity imparting unit 3 functions to suppress the vibration during the performance of the drum D from being transmitted to the floor and to exhibit the natural sound of the drum. In the following description, an example in which the drum D is a concert bass drum will be described. However, the present invention is not limited to this example, and various bass drums, snare drums, tam toms, and the like that constitute Japanese drums and drum sets. For example, a connected body in which a plurality of drums are connected, such as a multitom, may be used.

支持部２は、図３及び図４にも示すように、ドラムＤを左右側方から回動角変更可能に支承する角度調節機構４と、高さ方向に長く構成され、角度調節機構４を高さ位置変更可能に支持する支持部材５とより構成されている。角度調節機構４はドラムＤの回動角を変更することでドラム打面の角度を調整する機構である。支持部材５により角度調節機構４の取り付け高さを変更することで打面の高さも調節することができる。   As shown in FIGS. 3 and 4, the support portion 2 is configured to support the drum D from the left and right sides so that the rotation angle can be changed, and to be long in the height direction. It is comprised from the supporting member 5 supported so that a height position change is possible. The angle adjusting mechanism 4 is a mechanism for adjusting the angle of the drum striking surface by changing the rotation angle of the drum D. The height of the striking surface can be adjusted by changing the mounting height of the angle adjusting mechanism 4 by the support member 5.

角度調節機構４は、より詳しくは、ドラムＤを回動可能に支承する支承部７と、支持部材５に対して高さ位置変更可能に固定される固定部８とより構成されている。支承部７は、回動軸となる軸部７０を有するドラム胴側に固定されるブラケット部７Ａと、該ブラケット部７Ａの軸部７０を支承する軸受け部７Ｂとより構成されている。支承部７については、以下説明する本例の構造に何ら限定されず、従来から公知のドラムスタンドの支承構造を広く採用できる。   More specifically, the angle adjustment mechanism 4 includes a support portion 7 that supports the drum D so as to be rotatable, and a fixing portion 8 that is fixed to the support member 5 so that the height position can be changed. The support portion 7 includes a bracket portion 7A that is fixed to the drum body side having a shaft portion 70 that serves as a rotation shaft, and a bearing portion 7B that supports the shaft portion 70 of the bracket portion 7A. The support portion 7 is not limited to the structure of this example described below, and a conventionally well-known drum stand support structure can be widely adopted.

ブラケット部７Ａは、図５にも示すように、ドラム胴９０に緩衝材７１を介して固定されるブラケット本体７２と、該ブラケット本体７２から外方に突出する軸部７０とより構成され、ブラケット本体７２は、本例では平面視十字形状の板材よりなり、四方に延びる十字の腕部のドラム胴側の面にそれぞれ筒状の緩衝材７１が取り付けネジ（ボルトナット７７）で固定され、該緩衝材７１が取り付けネジ（ボルトナット７６）によりドラム胴９０に直接固定されている。   As shown in FIG. 5, the bracket portion 7 </ b> A includes a bracket main body 72 that is fixed to the drum body 90 via a cushioning material 71, and a shaft portion 70 that protrudes outward from the bracket main body 72. The main body 72 is made of a cross-shaped plate material in a plan view in this example, and cylindrical shock-absorbing materials 71 are fixed to the drum body side surfaces of the cross-shaped arm portions extending in four directions by attachment screws (bolt nuts 77), The cushioning material 71 is directly fixed to the drum cylinder 90 with a mounting screw (bolt nut 76).

緩衝材７１は、皮、ゴム、軟質樹脂等よりなる筒状成形体であり、図６にも示すように、ボルトナット７６、７７の各ナットには緩衝材７１の内周面に咬み込む埋込みナット（爪付きナット）が用いられている。   The buffer material 71 is a cylindrical molded body made of leather, rubber, soft resin or the like. As shown in FIG. 6, each nut of the bolt nuts 76 and 77 is embedded into the inner peripheral surface of the buffer material 71. Nuts (nuts with claws) are used.

ブラケット部７Ａの軸部７０は、図３〜図５に示すように金属製の軸体７０ａの軸方向途中部又は先端部に大径軸部７０ｂを有し、該大径軸部７０ｂが軸受け部７Ｂにより軸方向に移動しないように嵌め込まれ、且つ回動可能に支持される。このような大径軸部７０ｂは、軸受け部７Ｂが比較的小さい挟持力で軸部７０を確実に回動不能に固定することが可能となる点で好ましい。   As shown in FIGS. 3 to 5, the shaft portion 70 of the bracket portion 7 </ b> A has a large-diameter shaft portion 70 b at the middle portion or the tip portion in the axial direction of the metal shaft body 70 a, and the large-diameter shaft portion 70 b is a bearing. The portion 7B is fitted so as not to move in the axial direction, and is rotatably supported. Such a large-diameter shaft portion 70b is preferable in that the shaft portion 70 can be securely fixed in a non-rotatable manner with a relatively small clamping force.

ブラケット部７Ａとともに支承部７を構成する軸受け部７Ｂは、図７にも示すように、半割状の下側受け部７３と上側受け部７４の組み合わせにより構成される。下側受け部７３は、連結材４０の上端部に固定され、上側受け部７４は、一端部７４ａが下側受け部７３又は連結材４０上端部に片持ち状に回動可能に支持され、他端部７４ｂに、下側受け部７３の端部７３ｂに回動可能に設けた係止部材７５により係止される凹溝７４ｃが形成されている。   As shown in FIG. 7, the bearing portion 7 </ b> B that constitutes the support portion 7 together with the bracket portion 7 </ b> A is configured by a combination of a halved lower receiving portion 73 and an upper receiving portion 74. The lower receiving portion 73 is fixed to the upper end portion of the connecting member 40, and the upper receiving portion 74 is supported so that the one end portion 74a can be pivoted in a cantilever manner on the lower receiving portion 73 or the connecting member 40 upper end portion, The other end 74b is formed with a concave groove 74c that is locked by a locking member 75 that is rotatably provided at the end 73b of the lower receiving portion 73.

これら下側受け部７３と上側受け部７４の間に上記軸部７０の大径軸部７０ｂを挟み込み、係止部材７５を凹溝７４ｃに係合することで軸部７０を回動不能に挟持し、ドラムＤを任意の角度位置に安定保持することができる。角度を変更する際は、係止部材７５を凹溝７４ｃから外すことで挟持力を緩め、軸部７０を任意の角度に回動させた状態で再び係止部材７５を凹溝７４ｃに係止させ、下側受け部７３と上側受け部７４の間に軸部７０を再び挟持させることで当該角度に固定することができる。尚、本例では左右双方とも下側受け部７３と上側受け部７４の間に挟持して固定するようにした構造であるが、左右何れか一方のみこのように挟持するように構成し、他方は係止部材７５を係合しても挟持せず、回動するように軸部７０を支持するように構成してもよい。   The large-diameter shaft portion 70b of the shaft portion 70 is sandwiched between the lower receiving portion 73 and the upper receiving portion 74, and the locking member 75 is engaged with the concave groove 74c so that the shaft portion 70 is unrotatably clamped. Thus, the drum D can be stably held at an arbitrary angular position. When changing the angle, the clamping force is loosened by removing the locking member 75 from the concave groove 74c, and the locking member 75 is locked again in the concave groove 74c with the shaft portion 70 rotated to an arbitrary angle. Then, the shaft portion 70 can be sandwiched again between the lower receiving portion 73 and the upper receiving portion 74, and the angle can be fixed. In this example, both the left and right sides are sandwiched and fixed between the lower receiving portion 73 and the upper receiving portion 74. However, only one of the left and right sides is sandwiched in this way, and the other May be configured to support the shaft portion 70 so as to rotate without being held even when the locking member 75 is engaged.

下側受け部７３及び上側受け部７４は、合成樹脂製の本体の外側に金属カバー部材７３Ｃ、７４Ｄを備えている。合成樹脂製とすることで軸部７０との回動方向への摩擦力を高め、軸部７０を挟持することでより確実に回動不能に固定できるように構成されている。金属カバー部材７３Ｃ、７４Ｄは補強のため設けられた部材であり、金属カバー部材７４Ｃには凹溝７４ｃに対応する位置に同じく凹溝７４ｄが形成され、その他ネジ孔等に対応する位置にはネジを通す通孔が形成されている。   The lower receiving portion 73 and the upper receiving portion 74 include metal cover members 73C and 74D on the outside of the synthetic resin main body. By being made of synthetic resin, the frictional force in the rotation direction with the shaft portion 70 is increased, and the shaft portion 70 is sandwiched so that the shaft portion 70 can be securely and non-rotatably fixed. The metal cover members 73C and 74D are members provided for reinforcement. The metal cover member 74C is similarly provided with a concave groove 74d at a position corresponding to the concave groove 74c, and other positions corresponding to the screw holes or the like with screws. A through hole is formed to pass through.

支承部７とともに角度調節機構４を構成する固定部８は、図７に示すように、連結材４０の下端部に設けられ、支持部材５を挟み込んでフランジ間をボルトナット８３で締めつけるΩ型の一対のパイプ固定金具８０、８１より構成されている。ボルトナット８３のナットは固定金具８０に溶接されていてもよい。一方の固定金具８０は、連結材４０の下端部に内側を外方に向けて溶接固定されており、内側面に突起部８２ａが突設されている。突起部８２ａは支持部材５の所定間隔おきに複数形成された係止孔５１に係合する突起であり、本例では図３に示すように、螺孔８０ａに外面側からボルト８２を螺合し、内側に突出したボルト先端部により構成されている。   As shown in FIG. 7, the fixing portion 8 that forms the angle adjusting mechanism 4 together with the support portion 7 is provided at the lower end portion of the connecting member 40, and is a Ω-type that sandwiches the support member 5 and tightens the flanges with bolts and nuts 83. It is composed of a pair of pipe fixing brackets 80 and 81. The nut of the bolt nut 83 may be welded to the fixing bracket 80. One fixing fitting 80 is welded and fixed to the lower end portion of the connecting member 40 with the inner side facing outward, and a protruding portion 82a protrudes from the inner side surface. The protrusions 82a are protrusions that engage with a plurality of locking holes 51 formed at predetermined intervals of the support member 5. In this example, as shown in FIG. 3, bolts 82 are screwed into the screw holes 80a from the outer surface side. And it is comprised by the bolt front-end | tip part protruded inside.

そして、当該突起部８２ａを係止孔５１に選択的に係合させたうえ、この固定金具８０に対して他方の固定金具８１を外側から上記ボルトナット８３、８３を用いて組み付けることで、固定部８は支持部材５の当該係止孔５１の高さ位置に固定される。   Then, the protrusion 82a is selectively engaged with the locking hole 51, and the other fixing fitting 81 is assembled to the fixing fitting 80 from the outside using the bolt nuts 83, 83, thereby fixing the fixing fitting 80. The part 8 is fixed to the height position of the locking hole 51 of the support member 5.

上記のとおり、角度調節機構４を構成する支承部７は連結材４０の上端部に設けられ、固定部８は連結材４０の下端部に設けられている。すなわち、支承部７は固定部８よりも上方の位置に設けられている。したがって、例えば図１０に示すようにドラム打面を水平にしてドラムの高さを最下方の位置に下げた場合に支持部材５がドラムよりも上に大きく突出して演奏の邪魔になるといったことを回避できる長さに容易に設定することができ、言い換えれば、長すぎない支持部材５を用いつつ十分に高い位置までドラムを調節することが可能である。   As described above, the support portion 7 constituting the angle adjusting mechanism 4 is provided at the upper end portion of the connecting member 40, and the fixing portion 8 is provided at the lower end portion of the connecting member 40. That is, the support part 7 is provided at a position above the fixed part 8. Therefore, for example, as shown in FIG. 10, when the drum striking surface is leveled and the height of the drum is lowered to the lowest position, the support member 5 protrudes greatly above the drum and interferes with the performance. It can be easily set to a length that can be avoided, in other words, it is possible to adjust the drum to a sufficiently high position while using the support member 5 that is not too long.

支持部材５は、中空又は中実の長尺部材よりなり、図８にも示すように、上側の領域に、高さ方向に直線状に延びて角度調節機構４を高さ位置変更可能に支持する支持領域Ｒ１が設けられ、これに連続する下側の領域Ｒ２に、回動軸の方向に直交する方向に屈曲する単又は複数の屈曲部３０、３１を備えた弾性付与部３が設けられ、更に、弾性付与部３に連続する下側の領域に、前後水平に延びる基台部５０として機能する領域Ｒ３が設けられている。   The support member 5 is formed of a hollow or solid long member, and as shown in FIG. 8, extends in a straight line in the height direction in the upper region and supports the angle adjustment mechanism 4 so that the height position can be changed. A support region R1 is provided, and a lower region R2 continuous with the support region R1 is provided with an elasticity applying portion 3 including one or a plurality of bent portions 30 and 31 bent in a direction orthogonal to the direction of the rotation axis. Furthermore, a region R3 functioning as a base portion 50 extending horizontally in the front-rear direction is provided in a lower region continuous with the elasticity applying portion 3.

すなわち、支持部材５である長尺部材には、支持部２以外に、弾性付与部３及び基台部５０が設けられ、長尺部材は上記の３つの領域Ｒ１〜Ｒ３を有し、上側の直線状の領域Ｒ１は支持部２の一構成要素として機能し、中間の屈曲した領域Ｒ２は弾性付与部３として機能し、下側の水平の延びる領域Ｒ３は基台部５０を構成している。本例では、支持部２と弾性付与部３と基台部５０とが左右独立した長尺部材よりそれぞれ構成されているが、一本の長尺部材を横方向に屈曲させて左右の基台部５０の後端同士が連続した左右一体の基台部、左右の支持部、及び弾性付与部を設けたものでもよい。   That is, the long member which is the support member 5 is provided with the elasticity applying portion 3 and the base portion 50 in addition to the support portion 2, and the long member has the above three regions R1 to R3, and the upper member The linear region R1 functions as one component of the support portion 2, the intermediate bent region R2 functions as the elasticity applying portion 3, and the lower horizontal extending region R3 forms the base portion 50. . In this example, the support part 2, the elasticity imparting part 3, and the base part 50 are each composed of long members that are independent on the left and right sides. A left and right integral base part in which the rear ends of the part 50 are continuous, a left and right support part, and an elasticity applying part may be provided.

また、上側の領域Ｒ１は、本例では水平な基台部５０に対して垂直な真上方向に延びているが、斜め方向でも勿論よい。また、固定部８の構造によっては、直線状でなくてもよい。支持部２として機能する上側の領域Ｒ１の軸方向長さは、支持部材５の高さ寸法を決め、そこから弾性付与部３の領域Ｒ２の高さ分を除いた長さを確保できる。支持部材５の高さ寸法は、図１０のように打面を水平にして最も下の位置にしたときに上端が打面から大きく突出せず、演奏の邪魔にならない程度に抑えることができる長さに決められる。これに基づいて確保される領域Ｒ１の長さがドラム高さの調節量（範囲）となる。領域Ｒ１には、少なくとも固定部８側に開口する係止孔５１が、長さ方向に沿って所定間隔おきに複数設けられている。   Moreover, although the upper region R1 extends in the directly upward direction perpendicular to the horizontal base 50 in this example, it may of course be in an oblique direction. Further, depending on the structure of the fixing portion 8, it may not be linear. The axial length of the upper region R1 functioning as the support portion 2 determines the height dimension of the support member 5, and the length excluding the height of the region R2 of the elasticity applying portion 3 can be secured. The height of the support member 5 can be suppressed to such an extent that the upper end does not protrude greatly from the striking surface when the striking surface is leveled as shown in FIG. It is decided. The length of the region R1 secured based on this becomes an adjustment amount (range) of the drum height. In the region R1, a plurality of locking holes 51 that open at least to the fixed portion 8 side are provided at predetermined intervals along the length direction.

中間の領域Ｒ２よりなる弾性付与部３は、支持領域Ｒ１の下端部に連続して下方から前方へ９０度屈曲した屈曲部３０と、そこから前方に延びる水平部３２と、その前端部で前方から後方へ１８０度屈曲した屈曲部３１とよりなり、このような屈曲した領域が弾性変形することでドラムの振動を下側の基台部５０に伝わらないようにする緩衝領域として機能する。   The elasticity applying portion 3 formed of the intermediate region R2 includes a bent portion 30 that is bent 90 degrees from the lower side to the front continuously from the lower end portion of the support region R1, a horizontal portion 32 that extends forward from the lower portion, and a front portion at the front end portion. The bent portion 31 is bent 180 degrees from the rear, and the bent region functions as a buffer region that prevents the vibration of the drum from being transmitted to the lower base 50 by elastic deformation.

尚、本例では前方へ屈曲させて水平部３２を設けた例であるが、前後へ２回以上屈曲させ、水平部を複数形成したものでもよい。例えば図９（ａ）に示すように支持領域Ｒ１から後方へ９０度屈曲した屈曲部３０Ａと、そこから後方へ延びる水平部３２Ａと、その後端部で後方から前方へ１８０度屈曲した屈曲部３０Ｂと、そこから前方に延びる水平部３２Ｂと、その前端部に形成される屈曲部３１とよりなるものも好ましい。このようにすれば支持領域Ｒ１の長さはより小さくなるが、弾性変形をより促進させることができる。   In this example, the horizontal portion 32 is provided by bending forward, but a plurality of horizontal portions may be formed by bending forward and backward twice or more. For example, as shown in FIG. 9A, a bent portion 30A bent 90 degrees backward from the support region R1, a horizontal portion 32A extending rearward therefrom, and a bent portion 30B bent 180 degrees forward from the rear at the rear end portion. And what consists of the horizontal part 32B extended ahead from there, and the bending part 31 formed in the front-end part is also preferable. In this way, the length of the support region R1 becomes smaller, but elastic deformation can be further promoted.

また、屈曲部３０、３１間を水平部３２としたが、水平ではなく斜めに傾斜させたものでもよい。例えば図９（ｂ）に示すように、９０度以上屈曲して前方斜め上方に向かう屈曲部とし、そこから斜め上方に直線状に延びる直線部３２Ｃと、その前端部に形成される同じく９０度以上屈曲して下方に向かう屈曲部３１Ａと、そこから下方に延びる直線部３３と、その下端部で９０度屈曲して後方に延びる屈曲部３１Ｂとよりなるものも、より長い距離を稼いで弾性を付与できる点で好ましい例である。水平部３２のように直線部で屈曲部間を繋いだ形状もの以外に、曲線状に連続的に繋いだ形状でもよい。   Further, the horizontal portion 32 is defined between the bent portions 30 and 31, but it may be inclined not diagonally but obliquely. For example, as shown in FIG. 9 (b), a bent portion that is bent 90 degrees or more and bent forward and obliquely upward is formed, and a straight portion 32C extending linearly and obliquely upward therefrom, and the same 90 degrees formed at the front end portion thereof. The bent portion 31A that is bent and directed downward, the straight portion 33 that extends downward therefrom, and the bent portion 31B that is bent 90 degrees at its lower end portion and extends rearward also earns a longer distance and is elastic. Is a preferable example in that can be imparted. In addition to the shape in which the bent portions are connected by the straight portions as in the horizontal portion 32, a shape in which the curved portions are continuously connected may be used.

支持部材５の領域Ｒ３よりなる左右の基台部５０の間には、単又は複数の連結部材６１、６２が渡設され、これら左右の基台部５０、５０及び連結部材６１、６２により基台６が構成されている。連結部材６１、６２の左右両端部の下面には、それぞれキャスター６３が付設されている。連結部材は１本としてもよい。また本例では、支持部材５の領域Ｒ３で基台６を構成したものであるが、例えば図９（ｃ）に示すように領域Ｒ３を省略し、代わりに基台６を構成する左右の部材を別途設けたもの等、支持部材５とは独立に基台６を構成したものでも勿論よい。   One or a plurality of connecting members 61 and 62 are provided between the left and right base portions 50 formed of the region R3 of the support member 5, and the left and right base portions 50 and 50 and the connecting members 61 and 62 serve as a base. A stand 6 is configured. Casters 63 are attached to the lower surfaces of the left and right ends of the connecting members 61 and 62, respectively. The number of connecting members may be one. Moreover, in this example, although the base 6 is comprised by area | region R3 of the supporting member 5, area | region R3 is abbreviate | omitted as shown, for example in FIG.9 (c), and the left and right members which comprise the base 6 instead. Of course, the base 6 may be configured independently of the support member 5, such as those provided separately.
