　前腕部６１の先端には、幅方向に貫通する貫通孔６１ｂが設けられており、当該貫通孔６１ｂには第一支承腕５に設けられた支承軸５１１が貫挿されている。これにより、第一支承腕５と第二支承腕６とは互いに対して回動可能に連結されている。 The tip of the forearm 61 is provided with a through hole 61b that penetrates in the width direction, and the support shaft 511 provided on the first support arm 5 is inserted into the through hole 61b. This allows the first support arm 5 and the second support arm 6 to be connected to each other so that they can rotate.
　前腕部６１の後端部には、幅方向に貫通する貫通孔６１ａが設けられている。貫通孔６１ａには第二支柱４の支承軸４１が貫挿されており、これにより第二支承腕６が軸支されている。 A through hole 61a passing through in the width direction is provided at the rear end portion of the forearm portion 61. The support shaft 41 of the second support column 4 is inserted through the through hole 61a, and thereby the second support arm 6 is pivotally supported.
　中腕部６２の後端部の外側には、幅方向に伸びだした棒状の把持部６２１が設けられている。バスケットボール用スタンド１の形態を切り替える場合、作業者は当該把持部６２１を把持して、第二支承腕６を上方へ持ち上げたり、下方へ押し下げたりする。 A rod-shaped grip portion 621 extending in the width direction is provided on the outside of the rear end portion of the middle arm portion 62. When changing the form of the basketball stand 1, the operator grasps the gripping portion 621 and lifts the second support arm 6 upward or pushes it downward.
　中腕部６２の後端は、薄板状の連結部材６０を介して後腕部６３に連結している。連結部材６０は、一端が中腕部６２の後端と回動可能に連結し、他端が後腕部６３の先端と回動可能に連結している。これにより、中腕部６２と後腕部６３は連結部材６０を支点として回動させられる。なお、本実施形態に関わらず、連結部材６０を介すことなく、中腕部６２と後腕部６３とを互いに対して回動可能に連結してもよい。 The rear end of the middle arm section 62 is connected to the rear arm section 63 via a thin plate-like connecting member 60. The connecting member 60 has one end rotatably connected to the rear end of the middle arm section 62 and the other end rotatably connected to the tip of the rear arm section 63. Thereby, the middle arm part 62 and the rear arm part 63 are rotated using the connecting member 60 as a fulcrum. Note that, regardless of this embodiment, the middle arm part 62 and the rear arm part 63 may be rotatably connected to each other without using the connecting member 60.
　後腕部６３の先端には、鉛直方向下方に垂下する錘８２の上端が回動可能に連結されている。これにより、形態の切替によって第二支承腕６の高さが変わり、第二支承腕６と水平面とのなす角が変わったとしても、錘８２は常に自重によって鉛直方向に垂下し、安定した状態をとる。
　本実施形態において、錘８２は、一対の第二支承腕６から下方へ伸びだした一対の板状の保持部材と、一対の保持部材の間に掛け渡すように配設される筒状の重しからなる。重しは、所定数量を上限としつつ任意の数量を配設することができ、これにより錘８２の重量を調整できる。その結果、種類によって重量が異なるバックボード７１やゴールリング７２（一般的にゴールリング７２は大きく分けて２種類、バックボード７１は３種類ほどあり、それぞれで重量が異なる）に応じて錘８２の重量を調整し、バスケットボール用スタンド１を安定させられる。
　なお、本実施形態にかかわらず、基台部２や第一支柱３、あるいは第二支柱４等に重しを設けて重量バランスをとることもできる。 The upper end of a weight 82 that hangs downward in the vertical direction is rotatably connected to the tip of the rear arm portion 63. As a result, even if the height of the second support arm 6 changes due to the switching of the form and the angle between the second support arm 6 and the horizontal plane changes, the weight 82 will always hang down in the vertical direction due to its own weight and remain in a stable state. Take.
In this embodiment, the weight 82 includes a pair of plate-shaped holding members extending downward from the pair of second support arms 6, and a cylindrical weight disposed so as to span between the pair of holding members. It consists of discipline. Any number of weights can be provided, with the upper limit being a predetermined number, so that the weight of the weight 82 can be adjusted. As a result, the weight 82 is adjusted according to the backboard 71 and goal ring 72, which have different weights depending on the type (generally, there are roughly two types of goal rings 72 and three types of backboards 71, each with a different weight). The basketball stand 1 can be stabilized by adjusting the weight.
Note that, regardless of this embodiment, it is also possible to balance the weight by providing weights on the base portion 2, the first support 3, the second support 4, etc.
　後腕部６３の後端部は、上方へ屈曲しており、後端部の幅方向外側には一対の棒状部材６３１が設けられている。この一対の棒状部材６３１は、第二支承腕６を高い位置又は低い位置に動かす場合に作業者が把持する把持部を構成する。また、一対の第二支承腕６の後端の間には、当該一対の第二支承腕６を連結する連結部材６３２が設けられている。この連結部材６３２により、第二支承腕６が幅方向外側に開いてしまったり、第二支承腕６の後端が第一支柱３よりも前方へ移動してしまったりするのを規制できる。
　また、後腕部６３には、第一支柱３と交差する位置において、幅方向に貫通する係止孔６３ａが設けられている。この係止孔６３ａは、第一支柱３の係止孔３ａ、３ｂと同じ径を有しており、当該第一支柱３の上方に設けられた係止孔３ａと後腕部６３の係止孔６３ａとを対応させて、あるいは当該第一支柱３の下方に設けられた係止孔３ｂと後腕部６３の係止孔６３ｂとを対応させて係止ピン８１を貫挿させることで、第一支柱３に対して後腕部６３を固定させられる。 The rear end portion of the rear arm portion 63 is bent upward, and a pair of rod-shaped members 631 are provided on the outside of the rear end portion in the width direction. The pair of rod-shaped members 631 constitute a gripping portion that is gripped by the operator when moving the second support arm 6 to a high position or a low position. Furthermore, a connecting member 632 that connects the pair of second support arms 6 is provided between the rear ends of the pair of second support arms 6 . This connecting member 632 can prevent the second support arm 6 from opening outward in the width direction and prevent the rear end of the second support arm 6 from moving forward of the first support column 3.
Further, the rear arm portion 63 is provided with a locking hole 63a that penetrates in the width direction at a position intersecting the first support column 3. This locking hole 63a has the same diameter as the locking holes 3a and 3b of the first support 3, and the locking hole 3a provided above the first support 3 and the rear arm portion 63 are locked. By inserting the locking pin 81 in correspondence with the hole 63a, or in correspondence with the locking hole 3b provided below the first support 3 and the locking hole 63b of the rear arm portion 63, The rear arm portion 63 is fixed to the first support column 3.
　このような第二支承腕６は、中腕部６２と後腕部６３をまっすぐにした場合、第二支柱４によって軸支されている軸支部分と第一支柱３に係止させられる係止部分の間の長さが、当該軸支部分と係止部分の直線的な距離よりも長い。この点、第二支承腕６は、当該軸支部分と係止部分の間に設けられる連結部材６０が中腕部６２又は後腕部６３と連結する箇所において折曲自在に構成されている。その結果、第二支承腕６は、第一形態では中腕部６２と後腕部６３が連結部材６０を介して連結する中間部分が、上方に持ち上がるように折曲して、また第二形態では当該中間部分が下方に垂れ下がるように折曲して第一支承腕５を支持する。 When the middle arm part 62 and the rear arm part 63 are straightened, such a second support arm 6 has a locking mechanism that locks the pivot part supported by the second support post 4 and the first support support 3. The length between the parts is longer than the linear distance between the pivot part and the locking part. In this respect, the second support arm 6 is configured to be bendable at the location where the connecting member 60 provided between the pivot portion and the locking portion connects with the middle arm portion 62 or the rear arm portion 63. As a result, in the first form, the second support arm 6 is bent so that the middle part where the middle arm part 62 and the rear arm part 63 are connected via the connecting member 60 is lifted upward, and in the second form Then, the intermediate portion is bent so as to hang downward to support the first support arm 5.
　このような構成からなるバスケットボール用スタンド１において、先端にバックボード７１が取り付けられている第一支承腕５の前腕部５１は、基台部２の前端に設けられた第二支柱４よりも前方へ十分な長さだけ張り出している。これにより、ゴールリング７２の下方において、プレーヤーは支障なく安全にプレーを行える。
　また、本実施形態にかかわらず、基台部２の上方はカバーで覆ってもよい。これにより、プレーヤーや作業者などが意図せず第一支承腕５や第二支柱４などに接触してケガをするといった事態を防げると共に見栄えもよくなる。 In the basketball stand 1 having such a configuration, the forearm portion 51 of the first support arm 5 to which the backboard 71 is attached to the tip is located forward of the second support column 4 provided at the front end of the base portion 2. It overhangs just enough length. As a result, players can safely play below the goal ring 72 without any hindrance.
Moreover, regardless of this embodiment, the upper part of the base part 2 may be covered with a cover. This prevents players, workers, etc. from unintentionally touching the first support arm 5, second support 4, etc. and causing injury, and improves the appearance.

A locking pin 81 is inserted through it. Further, the first support arm 5 is located below the second support arm 6, and is supported by the second support arm 6 so as to be suspended from above. The position of the first support arm 5 at this time is lower than the position in the first form, and the height of the goal ring 72 is the height determined for mini-basketball.
●高さ調整工程
　バスケットボール用スタンド１の形態を第一形態と第二形態の相互に切り替え、ゴールリング７２の高さを調整する工程について説明する。
　まず、第一形態から第二形態に切り替える場合について、図１の状態から、作業者は係止ピン８１を引き抜き、第一支承腕５の後腕部５２と第一支柱３の連結、及び第二支承腕６の後腕部６３と第一支柱３の連結を解除する。このとき、作業者は第一支承腕５の棒状部材５２１や第二支承腕６の棒状部材６３１、さらには把持部６２１を適宜に把持する。そして、図７に示すように、棒状部材６３１を後方へ倒すようにして後腕部６３の前端部を持ち上げると、連結部材６０によって後腕部６３に連結された中腕部６２の後端部が持ち上げられていき、第二支承腕６が上方へ持ち上げられる。また、これと同時に、棒状部材５２１を押し下げるようにして後腕部５２を下げ、第一支承腕５を下ろしていく。 ●Height adjustment process The process of switching the form of the basketball stand 1 between the first form and the second form and adjusting the height of the goal ring 72 will be explained.
First, when switching from the first form to the second form, the operator pulls out the locking pin 81 from the state shown in FIG. The connection between the rear arm portion 63 of the two support arms 6 and the first support column 3 is released. At this time, the operator appropriately grasps the rod-shaped member 521 of the first support arm 5, the rod-shaped member 631 of the second support arm 6, and further the grip portion 621. As shown in FIG. 7, when the front end of the rear arm 63 is lifted by tilting the bar member 631 backward, the rear end of the middle arm 62 connected to the rear arm 63 by the connecting member 60 is lifted, and the second support arm 6 is lifted upward. At the same time, the rear arm portion 52 is lowered by pushing down the rod-shaped member 521, and the first support arm 5 is lowered.
　このように第一支承腕５と第二支承腕６を動かしていくと、図８に示すように、第一支承腕５と第二支承腕６の位置が交差して入れ替わり、第一支承腕５が第二支承腕６の下方にくる。このまま、一対の第一支柱３それぞれに設けられた下方の係止孔３ｂ、第一支承腕５の係止孔５２ａ、及び第二支承腕６の係止孔６３ａが一直線上に並ぶように第一支承腕５と第二支承腕６を配置する。
　この一連の動作では、第一支承腕５の当接片５１２が第二支柱４から離れ、第一支承腕５は前方へ一旦膨らんでから後方へ戻るように弧状の軌跡をたどる。そして、第一支柱３の係止孔３ｂ、第一支承腕５の係止孔５２ａ、及び第二支承腕６の係止孔６３ａが一直線上に並ぶように第一支承腕５と第二支承腕６が配設された状態では、再び当接片５１２が第二支柱４に当接し、第一支承腕５の後方への移動が規制される。また、このとき、第一支承腕５の前腕部５１の下面側が掛架部材４２に当接し、第一支承腕５の下方への移動も規制される。 When the first support arm 5 and the second support arm 6 are moved in this way, the positions of the first support arm 5 and the second support arm 6 are crossed and swapped, as shown in FIG. 5 is located below the second support arm 6. In this state, the lower locking holes 3b provided in each of the pair of first support columns 3, the locking holes 52a of the first support arm 5, and the locking holes 63a of the second support arm 6 are aligned in a straight line. One support arm 5 and a second support arm 6 are arranged.
In this series of operations, the contact piece 512 of the first support arm 5 separates from the second support column 4, and the first support arm 5 follows an arcuate trajectory such that it once expands forward and then returns to the rear. Then, the first support arm 5 and the second support arm are aligned so that the locking hole 3b of the first support column 3, the locking hole 52a of the first support arm 5, and the locking hole 63a of the second support arm 6 are aligned. In the state in which the arm 6 is disposed, the contact piece 512 again contacts the second support column 4, and rearward movement of the first support arm 5 is restricted. Further, at this time, the lower surface side of the forearm portion 51 of the first support arm 5 comes into contact with the hanging member 42, and the downward movement of the first support arm 5 is also restricted.
　そして、一直線上に並んだ係止孔３ｂ、５２ａ、６３ａに係止ピン８１を貫挿させると、第一支承腕５と第二支承腕６が完全に固定され、バスケットボール用スタンド１は、ゴールリング７２の高さがミニバスケットボール用の高さに調節された第二形態となる。 Then, when the locking pins 81 are inserted through the locking holes 3b, 52a, and 63a arranged in a straight line, the first support arm 5 and the second support arm 6 are completely fixed, and the basketball stand 1 is fixed to the goal. In the second form, the height of the ring 72 is adjusted to the height for mini basketball.
　第二形態から第一形態に切り替える場合には、上述した第一形態から第二形態へ切り替える工程と逆の工程を経る。即ち、図５の状態から、作業者は係止ピン８１を引き抜き、第一支承腕５の後腕部５２と第一支柱３の連結、及び第二支承腕６の後腕部６３と第一支柱３の連結を解除する。このとき、作業者は第一支承腕５の棒状部材５２１や第二支承腕６の棒状部材６３１、さらには把持部６２１を適宜に把持する。そして、図８に示すように、棒状部材６３１を上方へ押し上げるようにして後腕部６３の前端部を下げると、連結部材６０によって後腕部６３に連結された中腕部６２の後端部が押し下げられていき、第二支承腕６が下げられる。また、これと同時に、棒状部材５２１を持ち上げるようにして後腕部５２を持ち上げ、第一支承腕５を上げていく。 When switching from the second form to the first form, the process reverse to the process of switching from the first form to the second form described above is performed. That is, the operator pulls out the locking pin 81 from the state shown in FIG. Disconnect support column 3. At this time, the operator appropriately grasps the rod-shaped member 521 of the first support arm 5, the rod-shaped member 631 of the second support arm 6, and further the grip portion 621. Then, as shown in FIG. 8, when the front end of the rear arm 63 is lowered by pushing the bar member 631 upward, the rear end of the middle arm 62 connected to the rear arm 63 by the connecting member 60 is pushed down, and the second support arm 6 is lowered. At the same time, the rear arm portion 52 is lifted by lifting the rod-shaped member 521, and the first support arm 5 is raised.
　このように第一支承腕５と第二支承腕６を動かしていくと、図７に示すように、第一支承腕５と第二支承腕６の位置が交差して入れ替わり、第一支承腕５が第二支承腕６の上方にくる。このまま、一対の第一支柱３それぞれに設けられた上方の係止孔３ａ、第一支承腕５の係止孔５２ａ、及び第二支承腕６の係止孔６３ａが一直線上に並ぶように第一支承腕５と第二支承腕６を配置する。
　この一連の動作では、第一支承腕５の当接片５１２が第二支柱４から離れ、第一支承腕５は前方へ一旦膨らんでから後方へ戻るように弧状の軌跡をたどる。そして、第一支柱３の係止孔３ｂ、第一支承腕５の係止孔５２ａ、及び第二支承腕６の係止孔６３ａが一直線上に並ぶように第一支承腕５と第二支承腕６が配設された状態では、再び当接片５１２が第二支柱４に当接し、第一支承腕５の後方への移動が規制される。 When the first support arm 5 and the second support arm 6 are moved in this way, as shown in FIG. 5 is located above the second support arm 6. In this state, the upper locking holes 3a provided in each of the pair of first support columns 3, the locking holes 52a of the first support arm 5, and the locking holes 63a of the second support arm 6 are aligned in a straight line. One support arm 5 and a second support arm 6 are arranged.
In this series of operations, the contact piece 512 of the first support arm 5 separates from the second support column 4, and the first support arm 5 follows an arcuate trajectory such that it once expands forward and then returns to the rear. Then, the first support arm 5 and the second support arm are aligned so that the locking hole 3b of the first support column 3, the locking hole 52a of the first support arm 5, and the locking hole 63a of the second support arm 6 are aligned. In the state in which the arm 6 is disposed, the contact piece 512 again contacts the second support column 4, and rearward movement of the first support arm 5 is restricted.
　そして、一直線上に並んだ係止孔３ａ、５２ａ、６３ａに係止ピン８１を貫挿させると、第一支承腕５と第二支承腕６が完全に固定され、バスケットボール用スタンド１は、ゴールリング７２の高さが一般競技用の高さに調節された第一形態となる。 Then, when the locking pins 81 are inserted into the locking holes 3a, 52a, and 63a arranged in a straight line, the first support arm 5 and the second support arm 6 are completely fixed, and the basketball stand 1 is fixed to the goal. In the first form, the height of the ring 72 is adjusted to the height for general competitions.
　以上の本実施形態に係るバスケットボール用スタンド１によれば、容易にゴールリング７２の高さを一般競技用又はミニバスケットボール用の高さに調整できる。特に脚立などを用意しなくとも調整作業が行えるし、バックボード７１は常に水平面に対して直角に保持されるためバックボード７１の傾きを調整する必要ない。また、ゴールリング７２下のスペースも広く確保され、ゴールリング７２下におけるプレーにも支障がない。 According to the basketball stand 1 according to the present embodiment described above, the height of the goal ring 72 can be easily adjusted to the height for general competitions or mini-basketball. Adjustment work can be carried out without the need for a stepladder or the like, and since the backboard 71 is always held perpendicular to the horizontal plane, there is no need to adjust the inclination of the backboard 71. Furthermore, a wide space is secured under the goal ring 72, so there is no problem in playing under the goal ring 72.
