●Structure FIGS. 1 to 6 show a basketball stand 1 according to the present embodiment, of which FIGS. 1 to 4 show a first form, and FIGS. 5 and 6 show a second form. In the following description, the side where the goal ring 72 is provided will be referred to as the front, and the opposite side will be referred to as the rear. Further, in the horizontal direction, a direction perpendicular to the front-rear direction is defined as a left-right direction.
The basketball stand 1 mainly includes a base part 2 made of a rectangular frame, a pair of first supports 3 and a pair of second supports 4 erected on the base part 2, interlocking first support arms 5, and It is constituted by a pair of second support arms 6.

Each component, such as the base 2, first support pillar 3, second support pillar 4, first support arm 5, and second support arm 6, is made, for example, from a metal material that has been appropriately processed, and has at least sufficient rigidity to withstand the physical external forces applied during a game.
A backboard 71 is attached to the tip of the first support arm 5. The backboard 71 is in the form of a rectangular plate, and an annular goal ring 72 is provided in front of the backboard 71, and a net 73 is held by the goal ring 72.

●Base part 2
The base portion 2 is a portion for stably installing the basketball stand 1 on an installation surface. Although it has a rectangular shape in this embodiment, the shape is not particularly limited as long as the basketball stand 1 can be stably installed. Further, in this embodiment, wheels 21 are provided at the four corners of the rectangular shape on the bottom side of the base portion 2, so that the basketball stand 1 can be moved to a desired position. Note that the wheels 21 may be provided with regulating means such as a brake or a locking mechanism for regulating rotation when the basketball stand 1 is installed at a predetermined position.
Note that, regardless of this embodiment, the first support 3 and the second support 4 may be directly fixed to the installation surface without providing the base 2, and in this case, the basketball stand 1 cannot be moved. However, there is no problem in adjusting the height of the goal ring 72.

● First pillar 3
The pair of first support columns 3 are erected at the rear end of the base 2, approximately in the center in the width direction. Each of the pair of first support columns 3 is a rod-shaped member having a length in the vertical direction, and in this embodiment, is in the shape of a rectangular column. The pair of first support columns 3 are arranged side by side at a certain distance in the left-right direction.

Each of the pair of first columns 3 is provided with a pair of locking holes 3a and 3b on the upper outer side. The locking holes 3a and 3b are vertically spaced apart and penetrate in the width direction. Note that the hole provided above is the locking hole 3a, and the hole provided below is the locking hole 3b. Upper locking holes 3a provided in each of the pair of first columns 3 are provided at positions corresponding to each other, and a rod-shaped locking pin 81 is inserted through the pair of locking holes 3a arranged in a straight line. It looks like this. Similarly, the lower locking holes 3b provided in each of the pair of first columns 3 are also provided at corresponding positions, and a bar-shaped locking pin 81 is inserted through the locking holes 3b arranged in a straight line. It is designed to be inserted. Note that FIG. 1 shows a state in which the locking pin 81 is inserted through the locking hole 3a, and FIG. 5 shows a state in which the locking pin 81 is inserted in the locking hole 3b.
Note that the locking pin 81 is located in the first support column 3 along with a locking hole 3a of the first support column 3, a locking hole 52a of the first support arm 5, and a locking hole 63a of the second support arm 6, which will be described later. It constitutes a first locking means for locking the first support arm 5 and the second support arm 6. Further, the locking pin 81 is attached to the first support 3 together with a locking hole 3b of the first support 3, a locking hole 52a of the first support arm 5, and a locking hole 63a of the second support arm 6, which will be described later. A second locking means for locking the first support arm 5 and the second support arm 6 is configured.

Note that a rod-shaped hanging member 31 that has a length in the width direction and connects the pair of first columns 3 is spanned over the upper ends of the pair of first columns 3. This can prevent the first support arm 5, which will be described later, from slipping upward between the pair of first support columns 3.
Furthermore, a bar-shaped regulating member 32 extending outward in the width direction is provided below the locking hole 3b of the pair of first columns 3. Thereby, it is possible to prevent the second support arm 6 from falling onto the installation surface during a mode switching operation or the like.
Furthermore, a rod-shaped hanging member 33 that connects the pair of first columns 3 is spanned below the locking holes 3b of the pair of first columns 3. This can prevent the first support arm 5, which will be described later, from slipping downward between the pair of first support columns 3.

●Second pillar 4
The pair of second supports 4 are erected at the front end of the base portion 2 and approximately at the center in the width direction. The pair of second supports 4, like the first support supports 3, are rod-shaped members each having a length in the vertical direction, and in this embodiment, have a prismatic shape. On the other hand, in this embodiment, the second support column 4 is relatively longer than the first support column 3, and the upper end of the second support column 4 is located at a higher position than the upper end of the first support column 3.

A bearing shaft 41 extending outward in the width direction is provided above each of the pair of second support columns 4. This bearing shaft 41 is inserted into a through hole 61a provided in a second support arm 6, which will be described later, and supports the second support arm 6.
In this embodiment, the pair of second pillars 4 support the second support arm 6 via the support shaft 41, but other structures may be used as long as the second support arm 6 can be rotatably supported at the position where the support shaft 41 is provided.For example, the second support arm 6 and the second pillar 4 may each be provided with corresponding concave or convex portions, and the second support arm 6 may be pivotally supported on the second pillar 4 at that position.

In addition, as will be described later, where the first support arm 5 is passed between the pair of second supports 4, a rod-shaped hanging member 42 is used as a regulating member to prevent the first support arm 5 from lowering beyond a certain level. is provided between the pair of second supports 4. This hanging member 42 is placed in a position corresponding to the position taken by the first support arm 5 in the case where the first support arm 5 fixed at a predetermined position above or below is fixed below, that is, in the second form. It is provided and can also play the role of positioning.
In addition, in this embodiment, the second support column 4 is provided with a reinforcing member 43 as illustrated. The reinforcing member 43 is a rod-shaped member that is diagonally stretched approximately at the center of the second support 4 and the base portion 2, and is used to resist the external force applied from the front toward the basketball stand 1 during basketball play. Supports the second pillar 4.

● First support arm 5
The first support arm 5 is a rod-shaped member with a backboard 71 attached to its tip, and in this embodiment, is in the shape of a rectangular column. This first support arm 5 has a length in the front-rear direction. The width of the first support arm 5 is slightly smaller than both the distance between the pair of first columns 3 and the distance between the pair of second columns 4, and the first support arm 5 is provided so as to pass between the pair of first columns 3 and the pair of second columns 4. As described later, the first support arm 5 is fixed at a predetermined position above or below, and the height of the backboard 71 attached to the tip of the first support arm 5 can be adjusted depending on which position it is fixed at, thereby adjusting the height of the goal ring 72 attached to the backboard 71.

The first support arm 5 includes a forearm portion 51 that extends forward approximately horizontally, and a rear arm portion 52 that is bent from the rear end of the forearm portion 51 and extends rearward and diagonally downward.

The forearm portion 51 is passed between the pair of second support columns 4 and begins to extend forward. The back surface of a backboard 71 is fixed to the distal end of this forearm portion 51, so that the backboard 71 is supported by the first support arm 5. The fixing method is not particularly limited, and may be screwed, welded, or the like. Further, the backboard 71 is attached to the forearm portion 51 so that its front surface or back surface is perpendicular to the horizontal plane.

A support shaft 511 extending outward in the width direction is provided in the middle of the forearm portion 51. This support shaft 511 is inserted into a through hole 61b provided in a second support arm 6, which will be described later, and pivotally supports the second support arm 6.
In this embodiment, the first support arm 5 supports the second support arm 6 by the support shaft 511, but the first support arm 5 and the second support arm 6 are connected to each other at the position where the support shaft 511 is provided. Other structures may be used as long as the arms 6 are rotatably connected to each other. For example, the first support arm 5 and the second support arm 6 are provided with corresponding recesses or protrusions, respectively, so that the corresponding positions can be adjusted. The first support arm 5 and the second support arm 6 may be rotatably connected to each other.

As shown in FIG. 4, in the rear part of the forearm part 51, where the forearm part 51 intersects with the second support post 4, there are a pair of left and right tongue-shaped contact pieces 512 that contact the second support post 4. It is set in. The pair of abutting pieces 512 protrude outward in the width direction of the forearm portion 51, and when the pair of abutting pieces 512 abut against the pair of second supports 4, the first support arm 5 moves further rearward. be regulated from doing so. In this respect, it can be said that the abutting piece 512 constitutes a restricting portion that restricts the rearward movement of the first support arm 5. In addition, the contact piece 512 is in strong contact with the second support 4 so as to be pulled rearward in a state where the first support arm 5 and the second support arm 6 are fixed to the first support 3, and as a result, , it also restricts the forearm portion 51 from lowering.

The rear arm 52 is passed between the pair of first struts 3 , and its rear end portion extends rearward beyond the pair of first struts 3 .
A locking hole is provided in the rear arm 52, penetrating in the width direction at a position where the rear arm 52 intersects with the pair of first posts 3. This locking hole is provided on the axis of the locking pin 81 in Fig. 1 or Fig. 5, and will be referred to as "locking hole 52a" below for ease of explanation.
This locking hole 52a has the same diameter as the locking holes 3a, 3b of the first support 3, and the rear arm 52 can be fixed to the first support 3 by inserting the locking pin 81 into the locking hole 3a provided above the first support 3 and the locking hole 52a of the rear arm 52, or by matching the locking hole 3a provided below the first support 3 and the locking hole 52a of the rear arm 52.

The rear end of the rear arm 52 is bent downward, and a pair of rod-shaped members 521 are provided on the outer side of the rear end in the width direction. The pair of rod-shaped members 521 form a gripping portion that is gripped when adjusting the first support arm 5 to a higher or lower position, and also form a restricting portion that restricts the rear end of the first support arm 5 from slipping forward through the gap between the pair of first supports 3.

● Second support arm 6
The second support arms 6 are rod-shaped members provided in a pair on the widthwise outer sides of the pair of first support columns 3 and the pair of second support columns 4, and in this embodiment are formed in a rectangular column shape. The second support arms 6 have a length in the front-rear direction.

The pair of second support arms 6 each consist of a forearm 61 that extends forward almost horizontally, a middle arm 62 that bends from the rear end of the forearm 61 and extends rearward and diagonally downward, and a rear arm 63 that is connected to the rear end of the middle arm 62 via a connecting member 60 and extends rearward.

A through hole 61b is provided at the tip of the forearm 61 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.

A through hole 61a is provided at the rear end of the forearm 61, penetrating in the width direction. The support shaft 41 of the second support column 4 is inserted into the through hole 61a, thereby supporting the second support arm 6.

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.

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 section 62 and the rear arm section 63 may be rotatably coupled to each other without using the coupling member 60.

The upper end of a weight 82 hanging down vertically is rotatably connected to the tip of the rear arm 63. As a result, even if the height of the second support arm 6 changes due to the change in form and the angle between the second support arm 6 and the horizontal plane changes, the weight 82 always hangs down vertically due to its own weight and is in a stable state.
In this embodiment, the weight 82 is composed of 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. Any number of weights can be disposed with a predetermined number as an upper limit, thereby adjusting the weight of the weight 82. As a result, the weight of the weight 82 can be 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 about three types of backboards 71, each with a different weight), and the basketball stand 1 can be stabilized.
Regardless of this embodiment, weights can be provided on the base portion 2, the first support column 3, the second support column 4, etc. to achieve weight balance.

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.

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.

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.

●General competition specifications (first form)
Regarding the basketball stand 1 described above, FIGS. 1 and 2 show the structure of the first form, that is, when the basketball stand 1 is used in general competition specifications.
In the first form, the locking hole 3a provided above 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 arranged in a straight line. A locking pin 81 is inserted through it. Further, the first support arm 5 is located above the second support arm 6 and is supported upward by the second support arm 6. The position of the first support arm 5 at this time is higher than the position in the second form, and the height of the goal ring 72 is the height determined for general competitions.

-Mini basketball version (second form)
5 and 6 show a second embodiment, that is, a structure in which the basketball stand 1 is used in a mini-basketball setting.
In the second form, the locking pin 81 is inserted through the locking hole 3b provided below the first support post 3, the locking hole 52a of the first support arm 5, and the locking hole 63a of the second support arm 6, aligned in a straight line. The first support arm 5 is located below the second support arm 6, and is supported so as to be suspended from above by the second support arm 6. The position of the first support arm 5 in this state is lower than its position in the first form, and the height of the goal ring 72 is set to the height specified for mini-basketball.

Height Adjustment Process The process of switching the basketball stand 1 between the first form and the second form and adjusting the height of the goal ring 72 will be described.
First, in the case of switching from the first form to the second form, the worker pulls out the locking pin 81 from the state shown in Fig. 1 to release the connection between the rear arm 52 of the first support arm 5 and the first support column 3, and the connection between the rear arm 63 of the second support arm 6 and the first support column 3. At this time, the worker appropriately holds the rod-shaped member 521 of the first support arm 5, the rod-shaped member 631 of the second support arm 6, and the gripping portion 621. Then, as shown in Fig. 7, when the front end of the rear arm 63 is lifted by tilting the rod-shaped 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 rod-shaped member 521 is pushed down to lower the rear arm 52, and the first support arm 5 is lowered.

8, the positions of the first bearing arm 5 and the second bearing arm 6 are crossed and swapped, and the first bearing arm 5 is below the second bearing arm 6. In this state, the first bearing arm 5 and the second bearing arm 6 are positioned so that the lower locking holes 3b provided on each of the pair of first columns 3, the locking holes 52a of the first bearing arm 5, and the locking holes 63a of the second bearing arm 6 are aligned in a straight line.
In this series of movements, the abutment piece 512 of the first support arm 5 separates from the second support column 4, and the first support arm 5 follows an arc-shaped trajectory, expanding forward once and then returning backward. Then, in a state in which the first support arm 5 and the second support arm 6 are arranged 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 a straight line, the abutment piece 512 abuts against the second support column 4 again, and the backward movement of the first support arm 5 is restricted. At this time, the lower surface side of the forearm portion 51 of the first support arm 5 abuts against the hanging member 42, and the downward movement of the first support arm 5 is also restricted.

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.

When switching from the second form to the first form, the process is reversed from the process of switching from the first form to the second form described above. That is, from the state shown in FIG. 5, the worker pulls out the locking pin 81, and releases the connection between the rear arm portion 52 of the first support arm 5 and the first support column 3, and the connection between the rear arm portion 63 of the second support arm 6 and the first support column 3. At this time, the worker 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 the grip portion 621. Then, as shown in FIG. 8, when the front end of the rear arm portion 63 is lowered by pushing the rod-shaped member 631 upward, the rear end of the middle arm portion 62 connected to the rear arm portion 63 by the connecting member 60 is pushed down, and the second support arm 6 is lowered. At the same time, the rod-shaped member 521 is lifted to lift the rear arm portion 52, and the first support arm 5 is raised.

7, the positions of the first bearing arm 5 and the second bearing arm 6 are crossed and swapped, and the first bearing arm 5 comes above the second bearing arm 6. In this state, the first bearing arm 5 and the second bearing arm 6 are positioned so that the upper locking holes 3a provided on each of the pair of first posts 3, the locking holes 52a of the first bearing arm 5, and the locking holes 63a of the second bearing arm 6 are aligned in a straight line.
In this series of movements, the abutment piece 512 of the first support arm 5 separates from the second support pillar 4, and the first support arm 5 follows an arc-shaped trajectory, expanding forward once and then returning rearward. Then, when the first support arm 5 and the second support arm 6 are disposed so that the locking hole 3b of the first support pillar 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 a straight line, the abutment piece 512 abuts against the second support pillar 4 again, and the rearward movement of the first support arm 5 is restricted.

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.

According to the basketball stand 1 of this embodiment, the height of the goal ring 72 can be easily adjusted to the height for general competition or mini-basketball. The adjustment can be done without the need for a stepladder or the like, and the backboard 71 is always held at a right angle to the horizontal plane, so there is no need to adjust the inclination of the backboard 71. In addition, a large space is secured under the goal ring 72, so there is no hindrance to play under the goal ring 72.
