Description

スポーツ競技用電動車椅子Electric wheelchair for sports competition
　この発明は、車椅子フェンシングをはじめとするスポーツ競技で使用される電動車椅子に関する。 This invention relates to an electric wheelchair used in sports competitions including wheelchair fencing.
　パラリンピック競技種目のひとつである「車椅子フェンシング」では、ピスト（競技面）に台座を固定し、その台座に車椅子を相手競技者に対して１１０°斜め向きに固定し、その車椅子に競技者が座って剣を操る。車椅子が固定されているので、競技者は、移動して間合いをとるということができない。健常者のフェンシングでは、フットワークを駆使することで、小兵が大男を相手に勝利することも多々あるが、フットワークを使えない車椅子フェンシングでは、そのようなことがほとんどない。結局、腕の長い人が非常に有利であって、多くの場合で大柄な競技者が勝利する。 In “Wheelchair Fencing” which is one of the Paralympic events, a pedestal is fixed to a piste (competition surface), a wheelchair is fixed to the opponent at an angle of 110 ° to the opponent, and the athlete sits on the wheelchair. Manipulate the sword. Since the wheelchair is fixed, the competitor cannot move and get in time. In fencing for healthy people, troopers often win against big men by making full use of footwork, but in wheelchair fencing that cannot use footwork, there is almost no such thing. After all, long-skilled people are very advantageous, and in many cases big players win.
　出身県の代表としてフェンシングの全国大会への出場経験がある発明者は、フットワークを駆使してこそフェンシングの醍醐味があると考えている。そこで電動車椅子を用いる「車椅子フェンシング」を提案する。従来の電動車椅子としては、ＪＰ２０００－８４００９Ａ，ＪＰ２００４－６５８２６Ａ，ＪＰＨ１０－２２０Ａ，ＪＰ２０１１－１４２９３８Ａがある。 The inventor who has participated in the national competition of fencing as a representative of the prefecture from which he was born thinks that the best part of fencing is only when he makes full use of his footwork. Therefore, "wheelchair fencing" using an electric wheelchair is proposed. Conventional electric wheelchairs include JP2000-84009A, JP2004-65826A, JPH10-220A, and JP2011-142938A.

In this way, the position of the sheet part 11 can be easily changed. By doing in this way, the position of the seat part 11 can be finely adjusted, and it can match a player's preference.
　図１に示されているように、シート部１１は略菱形（略正方形）であり、中立位置にセットしたときにひとつの頂部１１ａが前端となる。この頂部１１ａから右前縁１１ｂが右斜め後ろ方向に延びている。また頂部１１ａから左前縁１１ｃが左斜め後ろ方向に延びている。 As shown in FIG. 1, the seat part 11 is substantially rhombus (substantially square), and when set at a neutral position, one apex part 11a becomes the front end. A right front edge 11b extends obliquely rearward from the top 11a. Further, a left front edge 11c extends obliquely leftward and rearward from the top portion 11a.
　シート部１１の右前縁１１ｂ及び左前縁１１ｃの下には、鞍型の金具（サドルバンド）が取り付けられている（ただし図示省略）。右前縁１１ｂ及び左前縁１１ｃのいずれかの鞍型金具（サドルバンド）に金属パイプ製又は金属シャフト製のフットレスト１２が挿入されて固定されている（図２及び図３参照）。固定する方法としては、フットレスト１２に形成した孔にピンを挿入して固定したり、フットレスト１２にネジ山を形成してナットで固定したりすればよい。図１及び図２では、右前縁１１ｂの下にフットレスト１２が取り付けられている。図３は、左前縁１１ｃの下にフットレスト１２が取り付けられている。後述するように、電気剣３０を左手で操る競技者は右前縁１１ｂに足がかかるように座って競技を行い、電気剣３０を右手で操る競技者は左前縁１１ｃに足がかかるように座って競技を行うので、フットレスト１２は、競技者にあわせて右前縁１１ｂにも左前縁１１ｃにも着脱自在になっている。 A saddle-shaped bracket (saddle band) is attached below the right front edge 11b and the left front edge 11c of the seat portion 11 (not shown). A footrest 12 made of a metal pipe or a metal shaft is inserted and fixed to a saddle-shaped metal fitting (saddle band) of either the right front edge 11b or the left front edge 11c (see FIGS. 2 and 3). As a fixing method, a pin may be inserted and fixed in a hole formed in the footrest 12, or a screw thread may be formed in the footrest 12 and fixed with a nut. In FIG.1 and FIG.2, the footrest 12 is attached under the right front edge 11b. In FIG. 3, the footrest 12 is attached below the left front edge 11c. As will be described later, a player who operates the electric sword 30 with his left hand sits with his foot on the right front edge 11b, and a player who operates the electric sword 30 with his right hand sits with his foot on the left front edge 11c. Thus, the footrest 12 is detachably attached to the right front edge 11b and the left front edge 11c in accordance with the player.
　また図２及び図３に示されているように、シート部１１の下には、脚固定バンド１３Ｌ，１３Ｒが取り付けられている。競技者がこの脚固定バンド１３Ｌ，１３Ｒを使用して脚を固定することで、上半身を激しく動かしても、電動車椅子１から転落しにくくなる。 As shown in FIGS. 2 and 3, leg fixing bands 13L and 13R are attached below the seat portion 11. The athlete fixes the legs using the leg fixing bands 13L and 13R, so that the athlete does not easily fall from the electric wheelchair 1 even if the upper body is moved violently.
　さらに図１に示されるように、平面視においてシート部１１の後方には、グリップ部１４が設けられている。このグリップ部１４は、図６に示されるように、シート部１１に座った競技者の腰の高さに位置する。グリップ部１４の形状は、特には限定されないが、図１では平面視においてシート部１１の後方に位置し、シート部１１に沿った略Ｖ字状になっている。そしてグリップ部１４の両端付近に操縦桿（ジョイスティック）１５（１５Ｒ及び１５Ｌ）が設けられている。競技者は、グリップ部１４を握りながらこの操縦桿１５（１５Ｒ，１５Ｌ）を操作することができる。 Further, as shown in FIG. 1, a grip portion 14 is provided behind the seat portion 11 in a plan view. As shown in FIG. 6, the grip portion 14 is located at the waist level of the athlete sitting on the seat portion 11. Although the shape of the grip part 14 is not specifically limited, in FIG. 1, it is located in the back of the sheet | seat part 11 in planar view, and has become the substantially V shape along the sheet | seat part 11. FIG. A control stick 15 (15R and 15L) is provided near both ends of the grip portion 14. The player can operate the control stick 15 (15R, 15L) while holding the grip portion 14.
　また図１に示されるように、平面視においてグリップ部１４の後方には、コントロールケーブルコネクター部１６０，ボディーコードコネクター部１６１及び電気ケーブルコネクター部１６２が設けられている。後述するように、コントロールケーブルコネクター部１６０には、電気剣３０につながるコントロールケーブル４０が接続される。ボディーコードコネクター部１６１には、電気剣３０につながるボディーコード４１が接続される。電気ケーブルコネクター部１６２には、リール（電気ケーブル巻取器）５０から延びる電気ケーブル５１が接続される。ボディーコードコネクター部１６１と電気ケーブルコネクター部１６２とは、電気的に接続されている。なお電気ケーブル５１を二重構造にして、外部から駆動用の電気（たとえば１２Ｖ又は２４Ｖの直流電気）を供給するようにしてもよい。このようにすれば、電動車椅子１にバッテリーを搭載する必要がないので、電動車椅子１を軽量化することができる。また競技時間が長くなってもバッテリー切れになることがない。 As shown in FIG. 1, a control cable connector 160, a body cord connector 161, and an electric cable connector 162 are provided behind the grip 14 in plan view. As will be described later, the control cable 40 connected to the electric sword 30 is connected to the control cable connector 160. A body cord 41 connected to the electric sword 30 is connected to the body cord connector portion 161. An electric cable 51 extending from a reel (electric cable winder) 50 is connected to the electric cable connector portion 162. The body code connector portion 161 and the electric cable connector portion 162 are electrically connected. The electric cable 51 may have a double structure, and driving electricity (for example, 12V or 24V DC electricity) may be supplied from the outside. In this way, since it is not necessary to mount a battery on the electric wheelchair 1, the electric wheelchair 1 can be reduced in weight. Also, the battery will not run out even if the competition time increases.
　ボディー１０の上部には緊急停止スイッチ１７が設けられている。この実施形態では、図１に示されているように３つの緊急停止スイッチ１７が設けられている。いずれかの緊急停止スイッチ１７が押されれば、駆動輪２０への電気供給が停止し、電動車椅子１は停止する。このように複数のスイッチ１７がボディー１０の上部に設けられることで万一の場合には、競技者だけでなく審判員等がスイッチ１７を操作することも可能であり、駆動輪２０を確実に停止させることができる。またボディー１０の下部には、図２，図３に示されているように、衝突防止センサー１８が設けられている。衝突防止センサー１８があるので、競技相手の電動車椅子などに近づき過ぎた場合には駆動輪２０への電気供給が停止し、これによっても競技者の安全が確保される。 The emergency stop switch 17 is provided on the upper part of the body 10. In this embodiment, three emergency stop switches 17 are provided as shown in FIG. If any one of the emergency stop switches 17 is pressed, the supply of electricity to the drive wheels 20 is stopped and the electric wheelchair 1 is stopped. Thus, in the unlikely event that a plurality of switches 17 are provided on the upper portion of the body 10, not only the competitors but also the judges can operate the switches 17, and the drive wheels 20 can be securely connected. Can be stopped. Further, as shown in FIGS. 2 and 3, a collision prevention sensor 18 is provided at the lower portion of the body 10. Since the collision prevention sensor 18 is provided, the power supply to the driving wheel 20 is stopped when the player is too close to the electric wheelchair of the competitor, thereby ensuring the safety of the athlete.
　またボディー１０には色ランプ部１０１が設けられている。本実施形態では、色ランプ部１０１は、ボディー１０を横断するように帯状に形成されている。この色ランプ部１０１は、ピストに設置される電気審判器（色ランプ）の役割を果たす。色ランプ部１０１は、ピストに設置される電気審判器（色ランプ）の代わりに又はピストに設置される電気審判器（色ランプ）に連動して電気審判器（色ランプ）とともに、白・赤・緑を点灯する。このような構成にすれば、競技に慣れていない観客にも競技者の勝敗が判りやすくなる。なお色ランプ部１０１の形状・大きさ・数量等は、一例に過ぎない。適宜変更可能である。 The body 10 is provided with a color lamp portion 101. In the present embodiment, the color lamp portion 101 is formed in a strip shape so as to cross the body 10. The color lamp unit 101 plays the role of an electric umpire (color lamp) installed in the fixie. The color lamp unit 101 is white / red together with the electric umpire (color lamp) instead of or in conjunction with the electric umpire (color lamp) installed on the fixie.・ Lit green. With such a configuration, it becomes easier for the spectator who is not used to the competition to understand the winner's victory or defeat. The shape, size, quantity, etc., of the color lamp unit 101 are merely examples. It can be changed as appropriate.
　電動車椅子１の車輪（駆動輪２０，従動輪２１）はボディー１０に隠れているが、一般的なものを使用すればよい。ホイールにモーターが内蔵されたさまざまなサイズ（車輪径）の電動車椅子用インホイールモーター駆動輪ユニットが種々のメーカーから市販されている。そのようなユニットを使用すれば、駆動輪２０を容易に作製することができる。車輪のスポークが剥き出しであると、競技者の剣３０がスポークに刺さったり抜けなくなるおそれがある。無理に抜こうとすると、曲がったり折れたりするなど物理的に競技ができなくなる。これに対して、本実施形態では、電動車椅子１の車輪（駆動輪２０，従動輪２１）がボディー１０に隠れているので、そのような事態に陥ることがなく、安全に競技を進めることができる。 The wheels (drive wheel 20 and driven wheel 21) of the electric wheelchair 1 are hidden in the body 10, but ordinary ones may be used. Various in-wheel motor-driven wheel units for electric wheelchairs with various sizes (wheel diameters) with motors built into the wheels are commercially available from various manufacturers. If such a unit is used, the drive wheel 20 can be produced easily. If the spokes of the wheels are bare, the competitor's sword 30 may be stuck in the spokes or not pulled out. If you try to force it out, you will not be able to physically compete, such as bending or breaking. On the other hand, in this embodiment, since the wheel (drive wheel 20, driven wheel 21) of the electric wheelchair 1 is hidden in the body 10, it is possible to safely advance the competition without falling into such a situation. it can.
　またこのモーターとバッテリーとの間にブレーカーを設けることで、万一バッテリーから過大な電流が流れた場合でも安全が確保される。 Also, by providing a breaker between this motor and the battery, safety is ensured even if an excessive current flows from the battery.
　また図２及び図３に示されているように、ボディー１０のシート後方壁１０ａには、留金具１９が設けられている。後述のように、この留金具１９に身体固定バンド１９０を連結することで競技者を電動車椅子１に固定する。またシート後方壁１０ａは競技者の腰の位置が後ろにズレ過ぎないようにする安定させる機能を果たす。 As shown in FIGS. 2 and 3, a fastener 19 is provided on the seat rear wall 10 a of the body 10. As will be described later, the athlete is fixed to the electric wheelchair 1 by connecting a body fixing band 190 to the clasp 19. Further, the seat rear wall 10a functions to stabilize the position of the athlete's waist so that it does not shift too far backward.
　図４は、電気剣３０を示す斜視図である。 FIG. 4 is a perspective view showing the electric sword 30.
　電気剣３０は、主として、ヒルト３１と、ガード３２と、ブレード３３とを含む。 The electric sword 30 mainly includes a hilt 31, a guard 32, and a blade 33.
　ヒルト３１は、競技者が握る部分である。ヒルト３１は、前端部分がガード３２に突き当てられて、ブレード３３がガード３２を貫通してヒルト３１に差し込まれて固定されている。ヒルト３１の前端部分には、操縦桿（ジョイスティック）３１５が取り付けられている。グリップ部１４の近傍の操縦桿１５（１５Ｒ，１５Ｌ）を操作することが困難な競技者もいる。このような競技者は、操縦桿３１５によって電動車椅子１を操縦する。 The hilt 31 is the part that the athlete holds. The front end portion of the hilt 31 is abutted against the guard 32, and the blade 33 penetrates the guard 32 and is inserted into the hilt 31 to be fixed. A control stick (joystick) 315 is attached to the front end portion of the hilt 31. Some athletes have difficulty operating the control stick 15 (15R, 15L) in the vicinity of the grip portion 14. Such a player controls the electric wheelchair 1 with the control stick 315.
　ガード３２の裏側には、図４に示されているように、ボディーコードコネクター３２１と、コントロールケーブルコネクター３２２とが設けられている。ボディーコードコネクター３２１には、ボディーコード４１が接続される。コントロールケーブルコネクター３２２には、操縦桿３１５の信号を取り出すコントロールケーブルが接続される。そしてコード・ケーブル類を隠すようにクッション３２０が配置されている。 As shown in FIG. 4, a body code connector 321 and a control cable connector 322 are provided on the back side of the guard 32. The body code 41 is connected to the body code connector 321. The control cable connector 322 is connected to a control cable for taking out a signal from the control stick 315. A cushion 320 is arranged so as to hide the cords and cables.
　図５は、電動車椅子１に各種電気コードを取り付けた状態を示す図である。 FIG. 5 is a diagram showing a state in which various electric cords are attached to the electric wheelchair 1.
　電動車椅子１のボディーコードコネクター部１６１に、電気剣３０につながれるボディーコード４１を接続する。また電気ケーブルコネクター部１６２に、リール（電気ケーブル巻取器）５０から延びる電気ケーブル５１を接続する。また必要があれば、コントロールケーブルコネクター部１６０に、電気剣３０につながれるコントロールケーブル４０を接続する。なおコントロールケーブルコネクター部１６０にコントロールケーブル４０が接続されると、操縦桿１５からの操作信号は無効になり、操縦桿３１５によって電動車椅子１が操縦されるようになる（オーバーライドシステム）。 The body cord 41 connected to the electric sword 30 is connected to the body cord connector portion 161 of the electric wheelchair 1. In addition, an electric cable 51 extending from a reel (electric cable winder) 50 is connected to the electric cable connector 162. If necessary, the control cable 40 connected to the electric sword 30 is connected to the control cable connector 160. When the control cable 40 is connected to the control cable connector 160, the operation signal from the control stick 15 becomes invalid and the electric wheelchair 1 is operated by the control stick 315 (override system).
　図６は、電動車椅子１の使用方法を説明する図である。なお図面の煩雑を避けるために各種電気コード・ケーブル類は省略されている。 FIG. 6 is a diagram for explaining how to use the electric wheelchair 1. Various electrical cords and cables are omitted in order to avoid complicated drawings.
　図６に示されているように、左手で電気剣３０を操る競技者は、フットレスト１２を右前縁１１ｂに取り付けて、右前縁１１ｂに足がかかるように座る。そして脚固定バンド１３で両脚を固定するとともに、身体固定バンド１９０を留金具１９に連結する。このようにすることで、競技者が電動車椅子１に固定される。そして右手でグリップ部１４を握りつつ、操縦桿１５（１５Ｒ）を操作する。 As shown in FIG. 6, the player who operates the electric sword 30 with the left hand attaches the footrest 12 to the right front edge 11b and sits so that the right front edge 11b has a foot. Then, both legs are fixed by the leg fixing band 13 and the body fixing band 190 is connected to the clasp 19. In this way, the athlete is fixed to the electric wheelchair 1. Then, the control stick 15 (15R) is operated while holding the grip portion 14 with the right hand.
　以上説明したように本実施形態の電動車椅子１のシート部１１は、平面視において電動車椅子の進行方向前端となる頂部１１ａから右斜め後ろ方向に延びる右前縁１１ｂと左斜め後ろ方向に延びる左前縁１１ｃとを含んでいる。競技者は、この右前縁１１ｂ又は左前縁１１ｃに足がかかるように座るだけで、電気剣３０を操る腕が相手競技者に近づくように構えることができる。従来より「車椅子フェンシング」という競技はあったが、フェンシングに向く電動車椅子は皆無であり、車椅子を相手競技者に対して斜め向きに固定していた。電動車椅子でも、相手競技者に対して正対するものしかなく、仮に電動車椅子を使用してフェンシングを行って移動して間合いをとろうとすると、操縦が非常に困難であった。これに対して、本実施形態の電動車椅子１のシート部１１には、頂部１１ａから右斜め後ろ方向に延びる右前縁１１ｂと左斜め後ろ方向に延びる左前縁１１ｃとが含まれており、競技者は、この右前縁１１ｂ又は左前縁１１ｃに足がかかるように座るだけで、相手競技者に対して斜め向きに構えることができる。そしてこの状態で前進後進すれば、相手競技者に対する間合いも取りやすく、操縦が容易である。 As described above, the seat portion 11 of the electric wheelchair 1 according to the present embodiment includes the right front edge 11b extending in the diagonally backward right direction and the left front edge extending in the diagonally backward left direction from the top portion 11a that is the front end in the traveling direction of the electric wheelchair in plan view. 11c. The player can hold the arm that operates the electric sword 30 close to the opponent player by simply sitting so that the right front edge 11b or the left front edge 11c has a foot. There has been a competition called “wheelchair fencing” in the past, but there is no electric wheelchair suitable for fencing, and the wheelchair was fixed obliquely to the opponent. Even with an electric wheelchair, there is only one that faces the opponent, and if it was attempted to move by fencing using the electric wheelchair, it was very difficult to control. On the other hand, the seat portion 11 of the electric wheelchair 1 of the present embodiment includes a right front edge 11b extending from the top portion 11a in the diagonally backward right direction and a left front edge 11c extending in the diagonally backward left direction. The player can be held at an angle with respect to the opponent player simply by sitting with the right front edge 11b or the left front edge 11c. If the vehicle moves forward and backward in this state, it is easy to take a time for the opponent player and the maneuvering is easy.
　そしてこのシート部１１の後方であって、シート部１１に座った競技者の腰の高さに位置するようにグリップ部１４が設けられているので、競技者は競技中に上体を動かしながらグリップ部１４を握ってバランスを取ることができ、またこのグリップ部１４の近傍に操縦桿（ジョイスティック）１５Ｒ，１５Ｌが設けられているので、競技者は競技中にグリップ部１４を握った手で好きな操縦桿（ジョイスティック）１５Ｒ，１５Ｌを操作することができるので、右利きの競技者にも左利きの競技者にも好適である。また仮に電動車椅子１に背もたれがあってその背もたれの上にグリップ部１４が位置していては競技者は上体を動かしながらグリップ部１４を握ることがしづらくなるが、本実施形態の電動車椅子１では、グリップ部１４が、シート部１１に座った競技者の腰の高さという低い位置に配置されているので、競技者は競技中に上体を動かしながらグリップ部１４を握ってバランスを取りやすいのである。 And since the grip part 14 is provided so that it may be located behind the seat part 11 and at the height of the athlete sitting on the seat part 11, the athlete moves the upper body during the competition. Since the grip portion 14 can be balanced and joysticks 15R and 15L are provided in the vicinity of the grip portion 14, the athlete can hold the grip portion 14 during the competition. Since the favorite control sticks (joysticks) 15R and 15L can be operated, it is suitable for both right-handed and left-handed players. In addition, if the electric wheelchair 1 has a backrest and the grip portion 14 is positioned on the backrest, it is difficult for the athlete to grip the grip portion 14 while moving the upper body. 1, since the grip portion 14 is arranged at a low position of the waist of the athlete sitting on the seat portion 11, the athlete grasps the grip portion 14 while moving the upper body during the competition and balances it. It is easy to take.
　シート部１１は、台座部１１０の上で所定角度回動可能になっている。これによって、競技者は自分の嗜好に合うように、シート部１１の位置を微調整することができる。 The seat portion 11 is rotatable on the pedestal portion 110 by a predetermined angle. Thereby, the athlete can finely adjust the position of the seat portion 11 so as to suit his / her preference.
　シート部１１に取り付けるフットレスト１２は、シート部１１の右前縁１１ｂ及び左前縁１１ｃのいずれにも着脱自在である。本実施形態の電動車椅子１は、シート部１１の回動可能な角度が小さいが、フットレスト１２の取り付け位置を変更することで、電気剣３０を左手で操る競技者でも電気剣３０を右手で操る競技者でも、本実施形態の電動車椅子１を使用することができる。 The footrest 12 attached to the seat part 11 is detachable to both the right front edge 11b and the left front edge 11c of the seat part 11. Although the electric wheelchair 1 of the present embodiment has a small pivotable angle of the seat portion 11, a player who operates the electric sword 30 with the left hand can operate the electric sword 30 with the right hand by changing the mounting position of the footrest 12. Even the athlete can use the electric wheelchair 1 of the present embodiment.
　またシート部１１の下には、脚固定バンド１３Ｌ，１３Ｒが取り付けられている。この脚固定バンド１３Ｌ，１３Ｒで脚を固定することで、競技者が上半身を激しく動かしても、電動車椅子１から転落しにくくなる。さらに競技者が、身体固定バンド１９０を留金具１９に連結することで、競技者が電動車椅子１に固定され、一層転落しにくくなり、競技者の安全が確保されるのである。 Further, leg fixing bands 13L and 13R are attached under the seat portion 11. By fixing the legs with the leg fixing bands 13L and 13R, it is difficult for the athlete to fall from the electric wheelchair 1 even if the athlete moves the upper body vigorously. Furthermore, the athlete connects the body fixing band 190 to the clasp 19, so that the athlete is fixed to the electric wheelchair 1 and becomes more difficult to fall, and the safety of the athlete is ensured.
　ボディー１０の上部には緊急停止スイッチ１７が設けられている。この緊急停止スイッチ１７が押されれば、駆動輪２０への電気供給が停止し、電動車椅子１は停止する。緊急停止スイッチ１７がボディー１０の上部に設けられることで万一の場合には、競技者だけでなく審判員等がスイッチ１７を操作することも可能であり、競技者の安全が確保される。 The emergency stop switch 17 is provided on the upper part of the body 10. When the emergency stop switch 17 is pressed, the supply of electricity to the drive wheels 20 is stopped and the electric wheelchair 1 is stopped. In the unlikely event that the emergency stop switch 17 is provided on the upper portion of the body 10, not only the athlete but also a judge or the like can operate the switch 17 to ensure the safety of the athlete.
　ボディー１０の下部には、衝突防止センサー１８が設けられている。衝突防止センサー１８があるので、競技相手の電動車椅子などに近づき過ぎた場合には駆動輪２０への電気供給が停止し、これによっても競技者の安全が確保される。 The collision prevention sensor 18 is provided in the lower part of the body 10. Since the collision prevention sensor 18 is provided, the power supply to the driving wheel 20 is stopped when the player is too close to the electric wheelchair of the competitor, thereby ensuring the safety of the athlete.
　また従来、リール（電気ケーブル巻取器）５０から延びる電気ケーブル５１は、図７に示されるように、電気剣３０のボディーコードコネクター３２１に接続されていた。このようなものを、電動車椅子のフェンシングに使用すると、電動車椅子の前進後進にあわせて電気ケーブル５１が、リール（電気ケーブル巻取器）５０の内部に設けられたゼンマイバネの力で伸縮するが、競技者にとっては邪魔である。これに対して、本実施形態では、図５に示されているように、リール（電気ケーブル巻取器）５０から延びる電気ケーブル５１を電気ケーブルコネクター部１６２に接続するとともに、電気剣３０につながれるボディーコード４１をボディーコードコネクター部１６１に接続する。このようにすれば、競技者とボディーコード４１との相対的な位置関係が一定になるので、競技者が煩わしさを覚えることがなくなる。また図７の方式では、電気ケーブル５１が長く、特に、競技者から出た電気ケーブル５１がボディー１０の上からピストに垂れてリール５０に巻き取られる。ボディー１０の上の電気ケーブル５１は移動しやすく（暴れやすく）、またリール５０がへたるなどして電気ケーブル５１を巻き込む速度が遅くなると、電気ケーブル５１が撓みやすくなる。この状態で、電動車椅子が後退すると、電気ケーブル５１がボディー１０や駆動輪２０に踏まれたり巻き込まれたりするおそれがある。これに対して、本実施形態によれば、ボディー１０の上に電気ケーブル５１がなくなるので、また電気ケーブル５１を短くすることができ、ボディー１０や駆動輪２０よって踏んだり、干渉したり、巻き込むことを防止しやすくなる。 Conventionally, the electric cable 51 extending from the reel (electric cable winder) 50 has been connected to the body cord connector 321 of the electric sword 30 as shown in FIG. When such a thing is used for fencing of an electric wheelchair, the electric cable 51 expands and contracts by the force of the spring spring provided inside the reel (electric cable winder) 50 as the electric wheelchair moves forward and backward. It is a hindrance for the competitors. On the other hand, in the present embodiment, as shown in FIG. 5, an electric cable 51 extending from a reel (electric cable winder) 50 is connected to the electric cable connector portion 162 and connected to the electric sword 30. The body cord 41 is connected to the body cord connector portion 161. In this way, the relative positional relationship between the athlete and the body code 41 becomes constant, so that the athlete does not feel bothered. In the method of FIG. 7, the electric cable 51 is long, and in particular, the electric cable 51 coming out of the athlete is hung on the reel 50 by hanging from the top of the body 10 on a fixie. The electric cable 51 on the body 10 is easy to move (prone to be violent), and when the speed at which the electric cable 51 is wound is reduced due to the reel 50 sag or the like, the electric cable 51 is easily bent. If the electric wheelchair moves backward in this state, the electric cable 51 may be stepped on or caught in the body 10 or the drive wheel 20. On the other hand, according to the present embodiment, the electric cable 51 is not provided on the body 10, and the electric cable 51 can be shortened. The electric cable 51 can be stepped on, interfered with, or caught by the body 10 or the driving wheel 20. It becomes easy to prevent that.
　また電気ケーブル５１を二重構造にして駆動用の電気を外部から供給するようにすれば、電動車椅子１にバッテリーを搭載する必要がないので、電動車椅子１を軽量化することができる。また競技時間が長くなってもバッテリー切れになることがない。 Further, if the electric cable 51 is made to have a double structure and electricity for driving is supplied from the outside, it is not necessary to mount a battery on the electric wheelchair 1, so that the electric wheelchair 1 can be reduced in weight. Also, the battery will not run out even if the competition time increases.
　さらにボディー１０に、色ランプ部１０１が形成されているので、競技に慣れていない観客にも競技者の勝敗が判りやすい。 Furthermore, since the body 10 is provided with a color lamp portion 101, it is easy for a spectator who is not used to the competition to easily determine the winner or defeat of the athlete.
　（第２実施形態）
　図８は、グリップ部１４のバリエーションを示す図である。 (Second Embodiment)
FIG. 8 is a view showing a variation of the grip portion 14.
　なお以下では前述と同様の機能を果たす部分には同一の符号を付して重複する説明を適宜省略する。 In the following, parts that perform the same functions as those described above are given the same reference numerals, and redundant descriptions are omitted as appropriate.
　この実施形態では、グリップ部は、右グリップ１４Ｒ，左グリップ１４Ｌ，中央グリップ１４Ｃの３体に分割されている。そして各グリップの近傍に操縦桿（ジョイスティック）１５Ｒ，１５Ｌ，１５Ｃが配置されている。 In this embodiment, the grip portion is divided into three bodies: a right grip 14R, a left grip 14L, and a center grip 14C. In the vicinity of each grip, joysticks 15R, 15L, and 15C are arranged.
　競技者によっては、真後ろのグリップ部を握りたい人もいる。本実施形態のように３体のグリップ１４Ｒ，１４Ｌ，１４Ｃを設けることで、競技者が握ることができるグリップの選択肢が広がるので、競技者の嗜好に一層あわせることができる。また各グリップ１４Ｒ，１４Ｌ，１４Ｃが小形化することで、剛性か高くなり、力の強い競技者が操作しても変形しにくくなる。 Some athletes want to grip the grip part directly behind. By providing the three grips 14R, 14L, and 14C as in the present embodiment, the choices of grips that can be gripped by the athlete are expanded, so that it is possible to further match the preference of the athlete. Further, by reducing the size of each grip 14R, 14L, 14C, the rigidity becomes high, and it is difficult to deform even if operated by a strong player.
　（第３実施形態）
　図９は、グリップ部１４の別のバリエーションを示す図である。 (Third embodiment)
FIG. 9 is a diagram showing another variation of the grip portion 14.
　この実施形態では、グリップ部１４は、電動車椅子１の中心線上であって競技者の真後ろに、電動車椅子１の前後方向に延設されている。 In this embodiment, the grip portion 14 is extended in the front-rear direction of the electric wheelchair 1 on the center line of the electric wheelchair 1 and directly behind the competitor.
　競技者によっては、真後ろに前後方向に延びるグリップ部を握りたい人もいる。本実施形態のようにすることでも、競技者の嗜好に一層あわせることができる。 Some players want to grip the grip that extends in the front-rear direction directly behind. By doing like this embodiment, it can be matched more with a player's preference.
　（第４実施形態）
　図１０は、グリップ部１４のさらに別のバリエーションを示す図である。 (Fourth embodiment)
FIG. 10 is a view showing still another variation of the grip portion 14.
　この実施形態では、ボディー１０に、グリップ部１４及び操縦桿１５を挿入可能な複数組の孔１０４，１０５が形成されている。そして、孔１０４にグリップ部１４を挿入して固定するとともに、孔１０５に操縦桿１５を挿入して固定することで、グリップ部１４及び操縦桿１５の位置を自由に変更することができる。図１０では、第２実施形態（図８）の右グリップ１４Ｒに相当する位置にグリップ部１４が取り付けられている。なおグリップ部１４及び操縦桿１５の固定方法としては、グリップ部１４及び操縦桿１５の先端にネジ山を形成しておき、孔１０４及び孔１０５に貫通させた状態で、ボディー１０の裏側からナットで固定するようにすればよい。 In this embodiment, a plurality of sets of holes 104 and 105 into which the grip portion 14 and the control stick 15 can be inserted are formed in the body 10. And while inserting the grip part 14 in the hole 104 and fixing, and inserting and fixing the control stick 15 in the hole 105, the position of the grip part 14 and the control stick 15 can be changed freely. In FIG. 10, the grip part 14 is attached to a position corresponding to the right grip 14R of the second embodiment (FIG. 8). As a method for fixing the grip part 14 and the control stick 15, a screw thread is formed at the tip of the grip part 14 and the control stick 15 and penetrates through the hole 104 and the hole 105. It should be fixed with.
　このようにすれば、グリップ部１４及び操縦桿１５を無用に増やす必要がなく、コストを安価に抑えることができる。 In this way, there is no need to unnecessarily increase the grip portion 14 and the control stick 15, and the cost can be kept low.
　（第５実施形態）
　図１１は、シート部１１の位置を微調整するための機構のバリエーションを示す図である。 (Fifth embodiment)
FIG. 11 is a diagram showing a variation of a mechanism for finely adjusting the position of the sheet portion 11.
　この図１１に示されているように、シート部１１の下面には、扇状の歯車１１１が固設されており、その歯車１１１に歯車１１２が噛合し、その歯車１１２に歯車１１３が噛合する。このようになっているので、歯車１１３を回すことで歯車１１２が回転し、歯車１１１が回転する。また歯車比が大きいので、シート部１１に力をかけて回そうとしても、各歯車が動かない。したがって、シート部１１が固定される。なお歯車１１３にハンドルを取り付けて手動式とすれば、軽量であり製造コストも安価である。また歯車１１３にモーターを取り付けて電動式とすれば、力の弱い人でも操作しやすい。 As shown in FIG. 11, a fan-shaped gear 111 is fixed on the lower surface of the seat portion 11. The gear 112 meshes with the gear 111, and the gear 113 meshes with the gear 112. Thus, when the gear 113 is rotated, the gear 112 is rotated and the gear 111 is rotated. Further, since the gear ratio is large, each gear does not move even if a force is applied to the seat portion 11 to rotate it. Accordingly, the seat portion 11 is fixed. If a handle is attached to the gear 113 to make it a manual type, the weight is light and the manufacturing cost is low. Further, if a motor is attached to the gear 113 to make it electric, even a weak person can easily operate it.
　なお歯車１１３を軸方向にスライド移動するロック歯車としてもよい。この場合は、ロック歯車１１３を軸方向に逃がして、歯車１１２を回転操作して歯車１１１（シート部１１）の位置を調整する。そして所望の位置になったら、ロック歯車１１３を歯車１１２に噛合させることで歯車１１１（シート部１１）の位置を固定する。 The gear 113 may be a lock gear that slides in the axial direction. In this case, the lock gear 113 is released in the axial direction, and the gear 112 is rotated to adjust the position of the gear 111 (seat portion 11). When the desired position is reached, the lock gear 113 is engaged with the gear 112 to fix the position of the gear 111 (seat portion 11).
　以上のようにすれば、シート部１１の位置を一層調整しやすくなる。また調整範囲も広がる。図１１の場合は、歯車１１１（シート部１１）の可動範囲が１２０度程度であるので、フットレスト１２をシート部１１から着脱できない固定タイプにしても、電気剣３０を左手で操る競技者にも電気剣３０を右手で操る競技者にも対応可能である。 By doing so, it becomes easier to adjust the position of the seat portion 11. In addition, the adjustment range is expanded. In the case of FIG. 11, since the movable range of the gear 111 (seat portion 11) is about 120 degrees, even if the footrest 12 is a fixed type that cannot be detached from the seat portion 11, the athlete operating the electric sword 30 with the left hand It is also possible to handle a competitor who operates the electric sword 30 with the right hand.

FIG. 12 is a plan view showing a variation of the traveling unit 2 of the electric wheelchair 1. FIG. 13 is a perspective view showing a variation of the traveling unit 2 of the electric wheelchair 1.
　たとえば特開２０１１－１４２９７２号公報にあるように、４輪駆動の車椅子が知られている。本発明の電動車椅子１においても、各駆動輪（右前駆動輪２０ＦＲ，左前駆動輪２０ＦＬ，右後駆動輪２０ＲＲ，左後駆動輪２０ＲＬ）に対応するモーターを設けることで、４輪駆動タイプとしてもよい。 For example, as disclosed in Japanese Patent Application Laid-Open No. 2011-142972, a four-wheel drive wheelchair is known. Also in the electric wheelchair 1 of the present invention, a motor corresponding to each driving wheel (the right front driving wheel 20FR, the left front driving wheel 20FL, the right rear driving wheel 20RR, the left rear driving wheel 20RL) can be provided as a four wheel driving type. Good.
　また、この実施形態では、各駆動輪（右前駆動輪２０ＦＲ，左前駆動輪２０ＦＬ，右後駆動輪２０ＲＲ，左後駆動輪２０ＲＬ）には、複数本（この第６実施形態では１２本）のローラー２０１が回転自由に取り付けられている。このローラー２０１は、駆動車軸２００（右前駆動車軸２００ＦＲ，左前駆動車軸２００ＦＬ，右後駆動車軸２００ＲＲ，左後駆動車軸２００ＲＬ）の中心軸を通過する方向から見たときに、駆動車軸２００（右前駆動車軸２００ＦＲ，左前駆動車軸２００ＦＬ，右後駆動車軸２００ＲＲ，左後駆動車軸２００ＲＬ）に対して４５度の角度をなすように傾斜している。 In this embodiment, each drive wheel (right front drive wheel 20FR, left front drive wheel 20FL, right rear drive wheel 20RR, left rear drive wheel 20RL) has a plurality of rollers (12 in this sixth embodiment). 201 is rotatably attached. The roller 201 has a driving axle 200 (right front drive) when viewed from the direction passing through the central axis of the driving axle 200 (right front driving axle 200FR, left front driving axle 200FL, right rear driving axle 200RR, left rear driving axle 200RL). The vehicle is inclined at an angle of 45 degrees with respect to the axle 200FR, the left front drive axle 200FL, the right rear drive axle 200RR, and the left rear drive axle 200RL.
　このような構造を採用すると、図１３に矢印で示されているように、左前駆動輪２０ＦＬを右回転させるとともに左後駆動輪２０ＲＬを左回転させる。すなわち左前駆動輪２０ＦＬ及び左後駆動輪２０ＲＬを内側に回転させる。そして同時に、右前駆動輪２０ＦＲ及び右後駆動輪２０ＲＲを外側に回転させる。すると、図１３に太矢印で示されているように、走行ユニット部２が真左に移動する。 When such a structure is adopted, the left front driving wheel 20FL is rotated to the right and the left rear driving wheel 20RL is rotated to the left as indicated by an arrow in FIG. That is, the left front driving wheel 20FL and the left rear driving wheel 20RL are rotated inward. At the same time, the right front drive wheel 20FR and the right rear drive wheel 20RR are rotated outward. Then, as shown by a thick arrow in FIG. 13, the traveling unit 2 moves to the left.
　なお左前駆動輪２０ＦＬ及び左後駆動輪２０ＲＬを図１３の左後駆動輪２０ＲＬと同じ方向に回転させるとともに、右前駆動輪２０ＦＲ及び右後駆動輪２０ＲＲを図１３の右前駆動輪２０ＦＲと同じ方向に回転させれば、走行ユニット部２が前進する。 The left front driving wheel 20FL and the left rear driving wheel 20RL are rotated in the same direction as the left rear driving wheel 20RL in FIG. 13, and the right front driving wheel 20FR and the right rear driving wheel 20RR are rotated in the same direction as the right front driving wheel 20FR in FIG. If it rotates, traveling unit part 2 will move forward.
　また左前駆動輪２０ＦＬ及び左後駆動輪２０ＲＬを図１３の左後駆動輪２０ＲＬと同じ方向に回転させるとともに、右前駆動輪２０ＦＲ及び右後駆動輪２０ＲＲを図１３の右後駆動輪２０ＲＲと同じ方向に回転させれば、走行ユニット部２はその場右旋回（超信地旋回）する。 Further, the left front driving wheel 20FL and the left rear driving wheel 20RL are rotated in the same direction as the left rear driving wheel 20RL in FIG. 13, and the right front driving wheel 20FR and the right rear driving wheel 20RR are rotated in the same direction as the right rear driving wheel 20RR in FIG. , The traveling unit 2 turns right on the spot (super turning).
　このような走行ユニット部２を電動車椅子１に採用すれば、電動車椅子１は真横にも移動することができ、競技者が移動するバリエーションが増え、競技の面白みがさらに増す。 If such a traveling unit part 2 is adopted in the electric wheelchair 1, the electric wheelchair 1 can be moved sideways, the variation in which the athlete moves is increased, and the fun of the competition is further increased.
