[0028] The following describes an embodiment of the basketball stand 1 of the present invention with reference to the accompanying drawings.

[0029] The basketball stand 1 of this embodiment includes a mechanism for adjusting the height of the basketball hoop 72 to suit both standard competition and mini basketball specifications. This mechanism allows the basketball hoop 72 to be adjusted to the standard height of 3050 mm for general competition or 2600 mm for mini basketball. However, the basketball stand 1 of this embodiment is characterized by its ability to be adjusted to various heights. Through appropriate design, it can be configured to be adjustable to heights other than the aforementioned standard heights.

[0030] In the following description, the form of the basketball stand 1 in which the height of the basketball hoop 72 can be adjusted to a height corresponding to general competition specifications is referred to as the "first form", and the form of the basketball stand 1 in which the height of the basketball hoop 72 can be adjusted to a height corresponding to mini basketball specifications is referred to as the "second form".

[0031] Structure

[0032] Figures 1 to 6 The basketball stand 1 of this embodiment is shown, wherein: Figures 1 to 4 shows the first form, Figure 5 and Figure 6 In the following description, the side where the basketball hoop 72 is provided is referred to as the front, and the opposite side is referred to as the rear. Furthermore, the direction perpendicular to the front-back direction in the horizontal direction is referred to as the left-right direction.

[0033] The basketball stand 1 mainly comprises a base portion 2 having a rectangular frame, a pair of first pillars 3 and a pair of second pillars 4 erected on the base portion 2 , and a first supporting arm 5 and a pair of second supporting arms 6 linked therewith.

[0034] Furthermore, the base 2 , first support 3 , second support 4 , first support arm 5 , second support arm 6 and other components are made by appropriately processing metal materials, for example, and have sufficient rigidity to withstand at least the physical external forces applied during competition.

[0035] In addition, a backboard 71 is mounted on the front end of the first support arm 5. The backboard 71 is in the shape of a rectangular plate, and a ring-shaped basketball hoop 72 is provided on the front of the backboard 71. A net 73 is held in the basketball hoop 72.

[0036] ●Abutment 2

[0037] The base portion 2 is used to stably position the basketball stand 1 on a mounting surface. In this embodiment, the basketball stand 1 is rectangular, but its shape is not particularly limited as long as it can stably mount the basketball stand 1. In this embodiment, wheels 21 are provided at the four corners of the rectangular bottom surface of the base portion 2, allowing the basketball stand 1 to be moved to a desired position. The wheels 21 may also be provided with a limiting element, such as a brake or locking mechanism, to restrict rotation of the basketball stand 1 when it is positioned in a specified position.

[0038] Regardless of the present embodiment, the first support 3 and the second support 4 may be fixed directly to the installation surface without providing the base portion 2. In this case, the basketball stand 1 cannot be moved, but the height of the basketball frame 72 can be adjusted without any problem.

[0039] Pillar 1 3

[0040] A pair of first pillars 3 are erected at the rear end of the base portion 2 and approximately at its center in the width direction. Each of the first pillars 3 is a rod-shaped member having a length in the vertical direction, and in this embodiment, is a prismatic shape. The first pillars 3 are arranged side by side in the left-right direction at a predetermined distance.

[0041] A pair of latching holes 3a and 3b are provided on the upper outer sides of the pair of first pillars 3. The latching holes 3a and 3b are separated in the upper and lower parts and extend through the width direction. The latching hole 3a is provided on the upper part, and the latching hole 3b is provided on the lower part. The latching holes 3a provided on the upper part of the pair of first pillars 3 are provided at positions corresponding to each other, so that the rod-shaped latching pin 81 is inserted through the pair of latching holes 3a arranged in a straight line. Similarly, the latching holes 3b provided on the lower part of the pair of first pillars 3 are also provided at positions corresponding to each other, so that the rod-shaped latching pin 81 is inserted through the latching holes 3b arranged in a straight line. Figure 1 The locking pin 81 is shown to be inserted into the locking hole 3a. Figure 5 The state where the locking pin 81 is inserted into the locking hole 3b is shown.

[0042] The locking pin 81, together with the locking hole 3a 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, which will be described later, constitutes a first locking means for locking the first support arm 5 and the second support arm 6 to the first support column 3. Furthermore, the locking pin 81, together with 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, which will be described later, constitutes a second locking means for locking the first support arm 5 and the second support arm 6 to the first support column 3.

[0043] Furthermore, a rod-shaped hanger member 31 having a widthwise length and connecting the pair of first pillars 3 is provided across the upper ends of the pair of first pillars 3. This prevents the first support arm 5 described later from slipping upward between the pair of first pillars 3.

[0044] Furthermore, rod-shaped restricting members 32 extending outward in the width direction are provided below the locking holes 3b of the pair of first support posts 3. This prevents the second support arm 6 from falling onto the installation surface during the switching operation.

[0045] Furthermore, a rod-shaped hanger member 33 is provided below the locking holes 3b of the pair of first pillars 3 to connect the pair of first pillars 3. This prevents the first support arm 5 described later from slipping downward between the pair of first pillars 3.

[0046] Second Pillar 4

[0047] A pair of second pillars 4 are erected at the front end of the base portion 2, approximately at its center in the width direction. Like the first pillars 3, these second pillars 4 are vertically elongated rod-shaped members, and in this embodiment, are prismatic in shape. Furthermore, in this embodiment, the second pillars 4 are longer than the first pillars 3, with their upper ends positioned higher than the upper ends of the first pillars 3.

[0048] Support shafts 41 extending outward in the width direction are provided above the pair of second support columns 4. The support shafts 41 are inserted into through holes 61a provided in the second support arm 6 described later, and pivotally support the second support arm 6.

[0049] In this embodiment, a pair of second pillars 4 axially support the second supporting arm 6 through a support shaft 41. Other structures may also be used, as long as the second supporting arm 6 is rotatably supported at the position where the support shaft 41 is set. For example, corresponding recessed portions or convex portions may be respectively provided on the second supporting arm 6 and the second pillar 4, so that the second supporting arm 6 is pivotally supported by the second pillar 4 at this position.

[0050] As will be described later, the first support arm 5 passes between the pair of second support pillars 4. A rod-shaped hanger member 42 is provided between the pair of second support pillars 4 as a limiting member to prevent the first support arm 5 from descending beyond a certain height. When the first support arm 5 is fixed at a predetermined position, either upward or downward, the hanger member 42 is positioned corresponding to the position of the first support arm 5 when it is fixed downward, i.e., in the second configuration, and serves to position the first support arm 5.

[0051] In addition, in this embodiment, as shown in the figure, a reinforcing member 43 is provided on the second support 4. The reinforcing member 43 is a rod-shaped member that is obliquely provided across the approximate center of each of the second support 4 and the base portion 2. During a basketball game, the reinforcing member 43 supports the second support 4 against external forces acting on the basketball stand 1 from the front.

[0052] ●First supporting arm 5

[0053] The first support arm 5 is a rod-shaped component with a backboard 71 mounted at its front end. In this embodiment, it is prismatic in shape. The first support arm 5 has a length in the front-to-back direction. Furthermore, the width of the first support arm 5 is slightly smaller than the distance between the pair of first pillars 3 and the distance between the pair of second pillars 4. The first support arm 5 is arranged to pass between the pair of first pillars 3 and the pair of second pillars 4. Furthermore, as described later, the first support arm 5 is designed to be fixed at a predetermined position, either above or below. Depending on the position in which it is fixed, the height of the backboard 71 mounted to the front end of the first support arm 5 can be adjusted, and thus the height of the basketball hoop 72 mounted to the backboard 71 can be adjusted.

[0054] The first support arm 5 is composed of a front arm portion 51 extending substantially horizontally forward, and a rear arm portion 52 bent from the rear end of the front arm portion 51 and extending rearward and obliquely downward.

[0055] The forearm portion 51 extends forward through the pair of second support posts 4. The backboard 71 is secured to the front end of the forearm portion 51, thereby supporting the forearm 71 on the first support arm 5. The securing method is not particularly limited and may include screws, welding, or other methods. Furthermore, the backboard 71 is attached to the forearm portion 51 such that its front or back surface is perpendicular to the horizontal plane.

[0056] A support shaft 511 extending outward in the width direction is provided substantially in the middle of the front arm portion 51. The support shaft 511 is inserted into a through hole 61b provided in the second support arm 6 described later, thereby axially supporting the second support arm 6.

[0057] In this embodiment, the first supporting arm 5 axially supports the second supporting arm 6 through the supporting shaft 511. Other structures can also be used as long as the first supporting arm 5 and the second supporting arm 6 are rotatably connected at the position where the supporting shaft 511 is provided. For example, corresponding recessed portions or convex portions may be provided on the first supporting arm 5 and the second supporting arm 6, respectively, and at this position, the first supporting arm 5 and the second supporting arm 6 are rotatably connected relative to each other.

[0058] like Figure 4As shown, a pair of tongue-shaped contact pieces 512 are provided on the rear portion of the forearm 51 and at the portion where the forearm 51 intersects the second support 4. The contact pieces 512 protrude outward in the width direction of the forearm 51. When the contact pieces 512 contact the second support 4, the first support arm 5 is restricted from moving backward. From this point of view, it can be said that the contact pieces 512 constitute a restriction portion that restricts the backward movement of the first support arm 5. In addition, when the first support arm 5 and the second support arm 6 are fixed to the first support 3, the contact pieces 512 strongly contact the second support 4, thereby being pulled backward, which also restricts the forearm 51 from falling.

[0059] The rear arm portion 52 passes between the pair of first pillars 3 , and a rear end portion thereof extends rearward beyond the pair of first pillars 3 .

[0060] A locking hole is provided at the position where the rear arm portion 52 intersects with the pair of first pillars 3 and passes through in the width direction. Figure 1 or Figure 5 The locking hole 52a is provided on the axis of the locking pin 81 and is referred to as the "locking hole 52a" below for convenience of description.

[0061] The locking hole 52a has the same diameter as the locking holes 3a and 3b of the first pillar 3. By making the locking hole 3a provided above the first pillar 3 correspond to the locking hole 52a of the rear arm 52, or making the locking hole 3a provided below the first pillar 3 correspond to the locking hole 52a of the rear arm 52, the locking pin 81 is inserted through, thereby fixing the rear arm 52 to the first pillar 3.

[0062] The rear end of the rear arm portion 52 is bent downward, and a pair of rod-shaped members 521 are provided on the widthwise outer sides of the rear end. The pair of rod-shaped members 521 constitute a grip portion for gripping when adjusting the first support arm 5 to a higher or lower position, and also constitute a restricting portion that restricts the rear end of the first support arm 5 from slipping forward from between the pair of first pillars 3.

[0063] ●Second supporting arm 6

[0064] The second support arms 6 are rod-shaped members provided in pairs on the widthwise outer sides of the pair of first support posts 3 and the pair of second support posts 4. In this embodiment, the second support arms 6 are prismatic in shape.

[0065] Each of the pair of second support arms 6 includes a front arm portion 61 extending approximately horizontally forward, a middle arm portion 62 bent from the rear end of the front arm portion 61 and extending rearward and obliquely downward, and a rear arm portion 63 connected to the rear end of the middle arm portion 62 via a connecting member 60 and extending rearward.

[0066] A through hole 61b extending in the width direction is provided at the front end of the front arm portion 61, and the support shaft 511 provided in the first support arm 5 is inserted through the through hole 61b. Thus, the first support arm 5 and the second support arm 6 are rotatably connected to each other.

[0067] A through hole 61 a extending in the width direction is formed at the rear end of the front arm portion 61. The support shaft 41 of the second support column 4 is inserted through the through hole 61 a, thereby axially supporting the second support arm 6.

[0068] A rod-shaped grip 621 extending in the width direction is provided on the outer side of the rear end of the middle arm 62. When switching the form of the basketball stand 1, the operator grips the grip 621 and lifts the second support arm 6 upward or presses it downward.

[0069] The rear end of the middle arm portion 62 is connected to the rear arm portion 63 via a thin plate-shaped connecting member 60. One end of the connecting member 60 is rotatably connected to the rear end of the middle arm portion 62, and the other end is rotatably connected to the front end of the rear arm portion 63. This allows the middle arm portion 62 and the rear arm portion 63 to rotate about the connecting member 60 as a fulcrum. Regardless of this embodiment, the middle arm portion 62 and the rear arm portion 63 may also be rotatably connected relative to each other without using the connecting member 60.

[0070] The upper end of a counterweight 82, which hangs vertically downward, is rotatably connected to the front end of the rear arm 63. Therefore, even if the height of the second support arm 6 changes due to the change of configuration and the angle between the second support arm 6 and the horizontal plane changes, the counterweight 82 will always hang vertically due to its own weight and remain stable.

[0071] In this embodiment, the counterweight 82 is composed of a pair of plate-shaped retaining members extending downward from a pair of second support arms 6, and a cylindrical weight disposed so as to straddle the pair of retaining members. The weight can be adjusted by providing an upper limit on the specified number of weights. This allows the weight of the counterweight 82 to be adjusted based on the weights of the backboard 71 and basketball hoop 72, which vary depending on their type (typically, there are roughly two types of basketball hoops 72 and three types of backboards 71, each with a different weight), thereby stabilizing the basketball stand 1.

[0072] Regardless of the present embodiment, a weight can be provided on the base portion 2 , the first support 3 , the second support 4 , or the like to achieve weight balance.

[0073] The rear end of the rear arm portion 63 is bent upward, and a pair of rod-shaped members 631 are provided on the widthwise outer sides of the rear end. These rod-shaped members 631 constitute the grips that the operator grasps when moving the second support arm 6 to a higher or lower position. Furthermore, a connecting member 632 is provided between the rear ends of the pair of second support arms 6, connecting the pair of second support arms 6. This connecting member 632 prevents the second support arms 6 from expanding outward in the widthwise direction or from moving forward beyond the first support column 3.

[0074] Furthermore, the rear arm portion 63 is provided with a locking hole 63a extending therethrough in the width direction at a position intersecting the first support post 3. The locking hole 63a has the same diameter as the locking holes 3a and 3b of the first support post 3. By aligning the locking hole 3a provided on the upper side of the first support post 3 with the locking hole 63a of the rear arm portion 63, or aligning the locking hole 3b provided on the lower side of the first support post 3 with the locking hole 63b of the rear arm portion 63, and inserting the locking pin 81 therethrough, the rear arm portion 63 can be fixed to the first support post 3.

[0075] When the middle arm portion 62 and rear arm portion 63 of the second support arm 6 are straightened, the length between the pivotal portion supported by the second support post 4 and the locking portion secured to the first support post 3 is greater than the straight line distance between the pivotal portion and the locking portion. To this end, the second support arm 6 is configured so that the portion where the connecting member 60, provided between the pivotal portion and the locking portion, connects to the middle arm portion 62 or the rear arm portion 63 is freely bendable. Therefore, in the first configuration, the second support arm 6 bends, lifting the middle portion where the middle arm portion 62 and rear arm portion 63 are connected by the connecting member 60 upward. In the second configuration, this middle portion bends and hangs downward, supporting the first support arm 5.

[0076] In the basketball stand 1 having such a structure, the front arm portion 51 of the first support arm 5, to which the backboard 71 is attached at the front end, extends sufficiently forward from the second support column 4 provided at the front end of the base portion 2. This allows players to play the game safely and unhindered under the basketball hoop 72.

[0077] Regardless of the embodiment, the top of the base portion 2 can be covered by a cover. This prevents players or operators from accidentally touching the first support arm 5 or the second support column 4 and causing injuries, while also improving the aesthetics.

[0078] ●General competition specifications (first form)

[0079] For the basketball stand 1 mentioned above, Figure 1 、 Figure 2 The first form is shown, that is, the structure when the basketball stand 1 is used under general competition specifications.

[0080] In the first configuration, the locking hole 3a provided above 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 are aligned in a straight line, and the locking pin 81 is inserted therethrough. Furthermore, the first support arm 5 is positioned above the second support arm 6 and supported upward by the second support arm 6. At this point, the first support arm 5 is positioned higher than in the second configuration, and the height of the basketball hoop 72 is set to the standard for general competitions.

[0081] Mini basketball specifications (second form)

[0082] on the other hand, Figure 5 and Figure 6 The second form is shown, that is, a structure using the basketball stand 1 in a mini basketball format.

[0083] In the second configuration, the locking pin 81 is inserted through the locking hole 3b provided below 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, all aligned in a straight line. Furthermore, the first support arm 5 is positioned below the second support arm 6 and supported by it, thereby being suspended from above. At this point, the first support arm 5 is positioned lower than in the first configuration, and the height of the basketball hoop 72 is set to the specified height for a mini basketball.

[0084] ●Height adjustment process

[0085] The process of switching the shape of the basketball stand 1 between the first shape and the second shape and adjusting the height of the basketball hoop 72 will be described.

[0086] First, when switching from the first form to the second form, Figure 1 Starting from the state shown, the operator 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 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 the grip portion 621. Then, as shown in FIG. Figure 7 As shown, when the rod-shaped member 631 is tilted rearward, raising the front end of the rear arm 63, the rear end of the middle arm 62 connected to the rear arm 63 is raised via the connecting member 60, and the second support arm 6 is lifted upward. Simultaneously, the rod-shaped member 521 is pressed downward, lowering the rear arm 52 and the first support arm 5.

[0087] If the first supporting arm 5 and the second supporting arm 6 are moved in this way, Figure 8As shown, the positions of the first supporting arm 5 and the second supporting arm 6 are interchanged, with the first supporting arm 5 being located below the second supporting arm 6. In this state, the first supporting arm 5 and the second supporting arm 6 are arranged so that the locking holes 3b, the locking holes 52a of the first supporting arm 5, and the locking holes 63a of the second supporting arm 6, which are respectively provided below the pair of first pillars 3, are aligned in a straight line.

[0088] During this series of movements, the contact piece 512 of the first support arm 5 moves away from the second support post 4, and the first support arm 5 follows an arc-shaped trajectory, first protruding forward and then returning to the rear. Then, with the first support arm 5 and the second support arm 6 positioned so that the locking hole 3b of 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 are aligned, the contact piece 512 again contacts the second support post 4, restricting the rearward movement of the first support arm 5. At this point, the lower surface of the front arm portion 51 of the first support arm 5 contacts the hanger member 42, further restricting the downward movement of the first support arm 5.

[0089] When the locking pin 81 is inserted into 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 in the second form in which the height of the basketball frame 72 is adjusted to a height suitable for the mini basketball.

[0090] When switching from the second form to the first form, the process is opposite to the process of switching from the first form to the second form. Figure 5 Starting from the state of , the operator 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 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 the grip portion 621. Then, as Figure 8 As shown, when the front end of the rear arm 63 is lowered by pushing the rod-shaped member 631 upward, the rear end of the middle arm 62 connected to the rear arm 63 is pressed down by the connecting member 60, and the second support arm 6 is lowered. At the same time, the rear arm 52 is raised by lifting the rod-shaped member 521, thereby raising the first support arm 5.

[0091] If the first supporting arm 5 and the second supporting arm 6 are moved in this way, Figure 7 As shown, the positions of the first support arm 5 and the second support arm 6 are interchanged, with the first support arm 5 located above the second support arm 6. In this state, the first support arm 5 and the second support arm 6 are arranged so that the locking holes 3a provided below the pair of first pillars 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.

[0092] During this series of movements, the contact piece 512 of the first supporting arm 5 moves away from the second support post 4. The first supporting arm 5 follows an arcuate trajectory, first protruding forward and then returning to the rear. Then, with the first supporting arm 5 and the second supporting arm 6 positioned so that the retaining hole 3b of the first support post 3, the retaining hole 52a of the first supporting arm 5, and the retaining hole 63a of the second supporting arm 6 are aligned, the contact piece 512 again contacts the second support post 4, restricting the first supporting arm 5 from moving backward.

[0093] When the locking pin 81 is 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 in the first form in which the height of the basketball frame 72 is adjusted to a height suitable for general competitions.

[0094] According to the basketball stand 1 of this embodiment described above, the height of the basketball hoop 72 can be easily adjusted to a suitable height for general games or mini basketball. This adjustment can be performed without the need for a ladder or the like. Furthermore, since the backboard 71 is always perpendicular to the horizontal plane, there is no need to adjust the inclination of the backboard 71. Furthermore, a large space is provided below the basketball hoop 72, thereby preventing interference with the game being played there.
