スケットゴールがある。2. Description of the Related Art A basket goal is to support an arm of a predetermined length at a predetermined height, which has a backboard having a goal ring attached at right angles and which is connected to one end of the basket goal. There are types that can be freely suspended from the ceiling, and types that fix the arm to the wall of a gymnasium, etc., but most are types that are installed on the floor or the ground. In the case of the type that is installed on the floor or the ground, there are mobile basket goals in addition to those fixed in a fixed permanent position.

技にも利用できるようになる。The strut is always urged to rotate by the action of the first bullet in the upright direction to stand up, and the sudden upright motion is restrained by the second bullet being pulled. This state is maintained by locking the stopper with an operation of engaging one of the engaging portions of the arcuate elongated hole, and the stay maintains one end of the arm at a predetermined height. By changing the connecting position between one end of the stay and the other end of the arm, it can be used for mini competitions other than formal competitions .

When the stopper is released and the stay is pushed backwards or the prop is pushed backward against the force of the first bullet, the weight of the prop and arm then loads on the first bullet and the folding operation is performed by an external force. Is unnecessary, and the column rotates while accumulating the first bullet until it is supported by the gantry. At the same time, the arm is rotated through the stay and tilted and folded over the column. At this time, no load occurs on the second bullet.

れている。Next, the operation of the above embodiment will be described. In the state shown in FIG. 1, the column 6 is the first bullet 35.
Is urged to rotate in the clockwise direction in the drawing around the shaft 5 by the force of, the column 6 stands up in a state orthogonal to the base 3, and the stay 24 assists this and the fan-shaped plate. When the stopper 48 engages with the lower engaging portion 49a of the arc-shaped long hole 44 of 43, the support pillar 6 is maintained perpendicular to the support pillar connecting portion 4, and the arm 8 maintains a predetermined inclination angle. The ring 12 is held at a predetermined height.

は軽くて済む。Therefore, in the folding operation shown in FIG. 3 from the state shown in FIG. 1, after rotating the handle 46 to disengage the stopper 48 from the engaging portion 49a of the arc-shaped long hole 44, the stay 24 is mounted on the base. When a force is applied to push it toward the tail end side of 3, the column 6 tilts to the left in the figure with the shaft 5 as the center, and the arm 8 moves backward while rotating in the clockwise direction with the shaft 9 as the center. Therefore, this work is performed while resisting the force of the first bullet 35. However, as the support column 6 and the arm 8 fall rearward, their own weight is loaded on the first bullet 35, so that the operation force by a person can be light.

る。When the column 6 falls to a position where it is supported by the pedestal 37, the bracket 30 rotates counterclockwise about the shaft 5 so that the position of the shaft 31 is greater than the position of the shaft 5. In order to move further down, the first bullet 35 is pulled and the force is accumulated. Then, in order to maintain the state in which the column 6 is supported by the pedestal 37, the handle 46 is rotated to bring the stopper 48 into pressure contact with the other engaging portion 49 of the arcuate elongated hole 44, and the fan-shaped plate 43 and the column. The connecting portion 4 is fixed, and the support pillar 6 and the supporting pillar connection portion 4 are locked. If the lever 18 is rotated around the shaft 15 toward the arm receiver 7, the angle at which the upper portion of the backboard 10 projects outward can be reduced, and the overall folding can be made compact.

When the column 24 is lifted upward, the support column 6 is biased by the force of the first bullet 35, so that the column 6 can be easily rotated clockwise about the shaft 5 without requiring auxiliary power such as human power. And the arm 8 rises, and a predetermined tilted state is obtained via the stay 24. At this time, it is dangerous because the strut 6 suddenly rotates and stands up due to the stored force of the first bullet 35, which causes a shock, and therefore the wire 38 is pulled along with the standing up of the strut 6 and the second bullet 40. The column 6 is softly erected by pulling. Therefore, in order to maintain the upright state, the handle 46 is reversely rotated to press the stopper 48 into engagement with the engaging portion 49a of the arcuate elongated hole 44 to fix the fan-shaped plate 43 and the strut connecting portion 4, and 6 and the column connection part 4 are locked.

案出願公告されている（実公平４−２３５７４号）。Although the above-described expansion operation is a structure for the official game of basketball, it can be used as a structure for a so-called mini game. This may be done by rotating the handle 22 in advance and rotating the screw rod 20 to move the slide collar 21 to the lower part in the expanding operation. By doing this, as shown in FIG.
Since the left end side of the shaft 9 of the arm 8 rises to a higher position as compared with FIG. 1, the right end side of the arm 8 descends. At this time, the lever 18 is rotated about the shaft 15 so that the backboard 10 is perpendicular to the floor.
It is necessary to rotate to the side and adjust. Regarding the adjustment of the inclination angle of the backboard 10, a utility model application has been previously announced (Jpn. Pat. Appln. KOKAI No. 4-23574).
