Description

[Detailed description of the invention] Industrial application field The present invention relates to a basketball stand, and in particular, the height of the goal plate can be adjusted to both formal and non-formal use, and the goal plate is perpendicular to the floor. Concerning what is held in position.

2. Description of the Related Art In general, a basketball stand is constructed by holding a goal board at a predetermined height from the ground or floor surface, and supporting the goal board by attaching a net to a ring supported horizontally on the goal board. There are two different heights for this ring, one for official use and one for mini basketball competitions (abbreviated as non-official use), the former being 3050mm and the latter 2600mm. By the way, a mobile basketball stand is available that is convenient for playing or practicing basketball indoors, but although this mobile basketball stand is configured to be foldable, the goal board is not at a certain height. It is fixed only for formal use and cannot be used for both formal and non-formal use.

Problems to be solved by the invention By the way, a basket stand to be used indoors, especially a mobile one, is required to be lightweight. This is because if the mobile basketball stand becomes heavy, it may damage the floor of a gymnasium or the like. Therefore, it would be easy to add a structure that allows the height of the goal board to be freely adjusted so that the mobile basket stand can be used for both formal and non-formal purposes (for example, 59-30271), this has the problem of requiring a lightweight structure.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention includes a column that is fixed to the floor surface or movably erected in a vertical position, and a column that is pivotably supported by the column and can be tilted vertically. A basket stand comprising an arm, a backboard supported vertically on one end of the arm, and a ring supported horizontally on the backboard, wherein a lower part of the back surface of the backboard is connected to one end of the arm so as to be rotatable in the vertical direction. One end of an extendable connecting rod is rotatably connected to the backboard, one end of a cane of a predetermined length is rotatably connected coaxially to the other end of the connecting rod, and the other end of the cane is rotatably connected to the other end of the connecting rod. To provide a basket stand in which an end is rotatably connected to the upper part of the back surface of a backboard, and a handle having a common axis of the connecting rod and the cane rotatably connected is rotatably supported on the arm. do.

Effects According to the present invention, the goal board consisting of the back board and the ring can be adjusted to both the official height and the non-official height by the arm and can be used in common. As a result, the common axis of the cane and the connecting rod moves back and forth, and the backboard is held vertically by the cane and the connecting rod, thereby preventing the backboard from tilting due to changes in the angle of the arm.

One end of a length-adjustable stay 7 is pivotally supported at the short end of the arm 3, and the other end is connected to the cart 1.

As shown in FIG. 2, the arm 3 is rotatably supported via the column 2 and the shaft 8, and by adjusting the length of the stay 7, the height of both the state shown by the solid line and the state shown by the phantom line can be adjusted. It can be tilted so that the ring 5 is positioned at the right position. The state shown by the solid line is to maintain the official height, and the height of ring 5 is 3050 mm from the floor, and the state shown by the phantom line is to maintain the height for non-official use, and the height of ring 5 is 3050 mm from the floor. The height is 2600mm. In either case, the backboard 4 is located on a vertical line with respect to the floor surface, and the ring 5 is in a horizontal position. That is, the mounting base 9 of the back board 4 is attached to the long end of the arm 3 on the shaft 1.
At 0, a cane 11 and a connecting rod 12 are attached which support the back board 4 while being rotatably supported. As shown in FIG. 3, the relationship between the mounting base 9 and the arm 3 is such that a box-shaped recess 3a is formed at the tip of the arm 3, and a stopper 3b made of a bolt is provided on the upper wall thereof. A box-shaped protrusion 9a inserted into the recess 3a is rotatably connected by a shaft 10.
The shaft 10 is made of a cylindrical shaft, and a fastener 10a is attached to this cylindrical shaft.
is inserted, and the recess 3a and the protrusion 9a can be tightened and fixed. On the other hand, there is a through hole 9a in the upper part of the fixture 9.
is bored, and one end of the connecting rod 12 is pivotally supported in this through hole 9a. The connecting rod 12 is shown in Figures 4 and 5.
As shown in the figure, it consists of a T-shaped movable part 12a and a cylindrical fixed part 12b into which a stopper 12d is inserted at the end of the movable part 12a, and the fixed part 12b has a shaft 13. 12c is a damper for buffering the stopper 12d. The shaft 13 is made of a cylindrical shaft, and the rod 11 passes through its shaft hole. The cane 11 is U-shaped and has both open ends connected to the backboard 4. Shafts 14, 14 made of similar cylindrical shafts are inserted into the cane 11 on both sides of the shaft 13, and hinges 15, 15 are integrally connected to the shafts 14, 14, respectively. 15 is connected by shafts 18, 18 to a plate 17 with brackets 16, 16. Plate 17 is attached to arm 3 with bolts 19, 19.
Fixed. Furthermore, the shafts 14, 14 are provided with a hinge 1.
A handle 20 diametrically opposed to the handles 5 and 15 is integrally attached. In addition, 21 is the connecting rod 1
The fixing part 12b and the arm 3 are screwed together with a tightening screw for fixing the fixing part 12b of No. 2 to the arm 3.

Next, to explain the operation of the above embodiment, when it is to be used in the state shown by the solid line in FIG.
Pull the stay 7 to rotate the arm 3 about the shaft 8, and set the ring 5 to a predetermined height (3050 mm). In this state, the handle 20 is attached to the backboard 4 as shown in FIGS. 4 and 5.
The hinge 15 is rotated counterclockwise about the shaft 18, and the connecting rod 12 is contracted as a whole. The fixing portion 12b is fixed to the arm 3 by a tightening screw 21.

Next, in order to position the height of the ring 5 at 2600 mm in the state shown by the phantom line in FIG.
is extended, and the arm 3 is lowered on the backboard 4 side at a predetermined angle. The arm 3 tilts at a predetermined angle and stands still. Then, the tightening screw 21 is removed, and the handle 20 is raised and rotated clockwise about the shaft 18 to the state shown in FIGS. 6 and 7. Then, the hinge 15 will turn around 180 degrees, so
The fixed portion 12b is pulled to the right in the figure by the distance between the centers of the shafts 18 and 13. Therefore, the stopper 12d of the movable part 12a is the same as the damper 12c of the fixed part 12b.
At this time, pull the upper end of the mounting base 9 to the right in the figure so that the mounting base 4 is in a vertical position. Since the mounting base 9 is rotatable about the shaft 10, it allows the above movement. On the other hand, when the handle 20 is tilted clockwise, the cane 11 is pulled to the right in the figure, so the back board 4 as a whole is warped toward the back side, and in this state it is in a vertical position, and the ring 5 is held horizontally. . That is, based on the inclination angle of the arm 3 at the height of the official ring 5 (3050 mm), the back board 4 and its mounting base 9 are each in a vertical position, and the height of the informal ring 5 is (2600 mm). The moving distance of the cane 11 and the connecting rod 12 required for the backboard 4 and its mounting base 9 to be in a vertical position at the inclination angle of the arm 3 at the inclination angle of the arm 3 is the distance between the centers of the shafts 18 and 13.

In the formal mode (shown by solid lines in FIG. 2), the protrusion 9a of the mounting base 9 hits the stopper 3b, and the vertical position of the mounting portion 9 can be corrected by screwing in or out of the stopper 3b. Also, the present invention is not limited to mobile basket stands.

Effects of the invention According to the invention explained above, the basket stand can be set at both formal and non-formal heights, so one basket stand can have two uses. It is economical and improves the value of use. Moreover, the backboard must naturally be in a vertical position depending on its purpose, but this problem has been solved with a simple structure, making it lightweight, preventing the weight of the basket stand, and the simple structure making it easy to assemble and operate. It is also easy to disassemble and repair.
