Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a goal stand used primarily for basketball games played indoors such as gymnasiums.

Conventional Technology Conventional goal stands are of a fixed position type, so they get in the way when not in use in indoor spaces such as gymnasiums with limited area.Therefore, they are installed in a foldable and hanging structure on walls, ceilings, etc.

However, if the indoor space is large, such as in a gymnasium, or if a foldable hanging structure basketball goal cannot be installed due to the structure of the building, a goal stand with casters is placed on the floor and the goal stand is placed on the floor and can be moved manually if necessary. The goal stud is moved, carried to a designated location, and placed in place.

Even though it is equipped with casters, the weight of the goal stand itself is large, so it cannot be moved easily by hand, and it is difficult to fine-tune the movement and place it in a fixed position.
It's almost impossible.

Problems to be Solved by the Invention The goal stand can be moved by self-propulsion to a predetermined position in a room such as a gymnasium, and the position can be determined by fine adjustment, making handling the goal stand extremely simple and easy. This made it possible for even the weakest people, such as women and children, to move around.

Means for Solving the Problems: The main body 2 is equipped with rear wheel adjustable wheels 1 on both sides of the rear, and fixed front wheels 3 which jointly rotate at a fixed position are pivoted on both sides of the front of the main body 2. A geared motor 5 which is driven and rotated by an equipped pantry 4 and a front wheel fixed position type 3 on the front side are electrically connected by a sprocket gear 6 and a chain wheel 7 so as to drive and rotate, and are connected to the front, rear, left, right and outside of the body 2. A main body fixing stopper 8 is attached to the main body fixing stopper 8.

The main body fixing stopper 8 has a screw screw screwed into the support arm a protruding from the main body 2 so as to be perpendicular to the main body 2, and a handle C is attached to the upper protruding end of the screw punch opening, and a support piece (1) is attached to the lower protruding end of the screw punch opening. They are configured by being fixed to each other.

The front part of the main body 2 is spaced apart from each other at a predetermined distance on both sides.
A pair of front struts 9 and a pair of rear struts 1 arranged symmetrically on both sides at a distance from the pair of front struts 9.
0, and the lower ends of the front struts 9 and rear struts 10 on both front and rear sides are rotatably connected to the main body 2 by pivots 11. L of
the hydraulic cylinder 1 via the supporting frame 12.
The tip of the spindle 14 of No. 3 is rotatably connected to the main body 2 by a pivot 15, and the hydraulic cylinder ta is arranged so as to be inclined downward toward the rear. A hydraulic unit 17 operated by a battery 4 is operatively connected to the hydraulic cylinder 13, and the upper ends of the front column 9 and rear column 10 on both front and rear sides are pivoted to the rear of a substantially horizontal support arm 18 extending forward. A backboard 19 is vertically arranged and fixed to the front end of the support arm 18, and a ring 21 on which a cylindrical net 20 is suspended is fixed to the front surface of the backboard 19 so as to project horizontally.

Further, in the center of both sides at the front lower part of the main body 2, a lateral rolling wheel 23 is mounted vertically downward by a hydraulic cylinder 22 so as to roll in a direction perpendicular to the front wheel fixed position type 8, and the hydraulic cylinder 22 It is operatively connected to a hydraulic unit 17 .

Further, the front struts 9 on both sides and the front part of the main body 2 are covered by the base frame plate 24 (t), and a flexible buffer layer 25 is provided on the front surface of the base frame plate 24, and a skin cloth 26 is provided on the front surface of the base frame plate 24. Paste it.

A digital timer display 27 is installed at the upper part of the front strut 9 on both sides and at both rear sides of the support arm 18 so as to be visible from the front and both sides, respectively.

The maximum display time of this digital timer display 27 may be arbitrary, but is generally about a 30 second timer.

The geared motor 5, hydraulic unit 17, digital timer display 27, etc. are controlled by a control panel 28 installed on the rear upper surface of the main body 2, and a remote control box (not shown) connected to the control panel 28 is used as necessary. It is configured so that it can also be controlled by

Function: Since the basketball goal stand according to the present invention is constructed as described above, when it is stored, the support arm 18 is moved back to the E section of the main body 2 by retracting the spindle 14 of the hydraulic cylinder 13 as shown in FIG. Suspended horizontally.

By folding the support arm 18 to the lower position in this manner, the entire structure becomes lower and does not get in the way, and moreover, it becomes easier to handle.

When using the basketball stand, the following operations are performed by operating the remote control box or control panel 28.

That is, the front wheel fixed position type 3 is rotated by the drive rotation of the geared motor 5 and moved to a predetermined position.

At this time, since the rear wheels 1 on both rear sides freely rotate about the vertical axis, the direction change is easy.

Once the main body 2 has been moved to a predetermined position, the hydraulic cylinders 22 installed at the center of both sides of the front part are activated to lower the lateral rolling wheels 23, thereby lifting the main body 2 and moving the front wheels to the fixed position type 3. Raise it away from the floor.

Then, by pushing or pulling the main body 2 laterally, the front part can easily change direction.

When the main body 2 is in a predetermined position and in the correct direction, the hydraulic cylinder 22 is activated to retract the lateral rolling wheel 23 upward, thereby bringing the front wheel fixed position type 3 into contact with the floor surface.

Next, the main body 2 is fixedly placed on the floor using main body fixing stoppers 8 arranged at the front and back on both sides of the exterior of the main body 2. The main body fixing stopper 8 is attached to the branch piece (
1 is lowered, and even though the branch piece d touches the floor surface, the branch piece d is continued to be lowered and the entire body 2 is lifted and fixed.

Further, in order to ensure the levelness of the main body 2, the main body fixing stoppers 8 on both the front and rear sides are operated separately.

Once the main body 2 is fixed at a predetermined position, the spindle 14 of the hydraulic cylinder 13 is advanced to raise the front strut 9 and the rear strut 10 on both the front and rear sides. The arm 18 rises and projects forward.

In this condition, the Baskentball competition is held.
Because the ring 21 is too high for children to use,
As shown by the dashed line in FIG. 1, the spindle 14 of the hydraulic cylinder 13 is slightly moved back and the support arm 18 is set at a lower position for use in competitions.

Even if it accidentally collides with a goal stand while being used for a basketball game, it is extremely safe because the front part is covered with the flexible buffer layer 25.

Further, during the competition, it is convenient because the time limit or progress can be checked on the digital timer display 27 that can be seen from the front and both sides.

In addition, in order to move the main body 2, it is sufficient to use not only the geared motor 5 but also an oil motor or other suitable drive rotation mechanism, and also to move the front strut 9 and the rear strut 10,
The hydraulic cylinders 13 and 22 that control the lowering operation and the E-up operation of the lateral rolling wheel 28 are mechanisms that convert rotational motion into linear motion.

In other words, there is no problem in changing it to a forward and backward motion mechanism.

It is within the scope of the right to modify the structure of the present invention in any way as long as it achieves the intended purpose.

Effects of the Invention As described above, the main body of the goal stand can move by itself to a predetermined position by its own driving rotation mechanism, and the direction of the front part of the main body can be finely adjusted. It is extremely easy to fix and can be easily handled even by weak people such as women and children.

In addition, it can be kept in a low position when stored (when not in use), and can be raised to the correct position when used for competitions.
It doesn't get in the way and is extremely convenient.

Additionally, flexible cushioning layers are provided above and below the pillars on both sides of the front and the front of the main body, so even if you accidentally collide during a competition, you will be safe and your body will be protected from injury.
