The present invention relates to a protective net used in an indoor gymnasium or an indoor stadium. Especially, when playing a game of ball games such as basketball, volleyball, baseball, soccer, or handball, the equipment and lifespan of the stadium including the timekeeping scoreboard are displayed. It protects the facility and people by expanding the protection net by descending during the race, and protects the facility and the people, and can separate the stadium as needed when playing sports such as gymnastics, table tennis, badminton, etc. It is about a rigid protection net device.

In general, a ball game that requires a high speed pass or a male tends to cause a safety accident that damages the stadium's facilities or injures the audience due to the high speed of the ball.

In order to prevent such accidents, it is never easy to set up a protective net on the stadium in a timely manner, consuming unnecessary valuable time and labor.

In addition, when two sports were played in the same stadium or when different teams used the stadium, it was accompanied by operational difficulties such as decreased concentration of the game.

Therefore, if you install a partition on the stadium, you can expect the effect of efficient physical activity, and it is very difficult to block the compartment in time and structure, which may damage the floor of the floor.

The purpose of the present invention to solve these problems is to firstly to protect the various facilities and life of the stadium, and secondly to provide a protective stadium protective net that can maximize the effect of competition and athletic activities by separating the stadium. .

The main structural feature of this paper is to secure one end of the wire rope wound on the winding drum to the lower guard net and to transfer the motor from forward and reverse to the winding drum as an electrical signal. The protection net towed by the wire rope of the winding drum is to be raised and lowered.

Hereinafter, the configuration of the present invention in more detail by the accompanying drawings as follows.

As shown, the present invention consists of a driving device 2 installed on the frame 1 and a protection net 3 which is lifted up and down.

On the frame 1, a horizontal roller 5 is fixed to a fixed shaft 4 placed at appropriate intervals, and a vertical roller 6 is supported and supported by a bracket 7 in front thereof.

The drive device 2 is composed of a winding drum 11 which is fixed to the motor 8 and the output shaft of the reduction gear 9 and wound around the wire rope 10. The motor 8 and the reduction gear 9 are respectively The belt 13 is connected to the belt pulleys 12 and 12a provided on the shaft.

Both ends of the frame (1) can be fixed by a separate vertical strut (not shown), it can be fixed to the ceiling structure, etc. in the indoor stadium.

Protective net (3) made of a net structure is composed of upper and lower support (14, 15) and the upper support (14) is connected to the lower end of the rope (16) fixed to the frame (1) by a hook (17) And one end of the wire rope 10 drawn out from the winding drum 11 through the horizontal roller 5 and the vertical roller 6 and the through hole 18 of the frame 1 to the lower side of the frame 1. Penetrating through the upper support 14 and fixed to the hook 17a of the lower support 15 is fixed to both sides of the guard net (3) and the fixing ring (21).

The guard net 3 can also be used as a partition using a conventional fabric or the like.

In addition, the wire rope 10 may be pulled out from the winding drum 11 without being oriented by the horizontal roller 5 and then directly caught by the vertical roller 6 and horizontally and vertically with the winding drum 11. As the interval of (6) becomes longer, a balance roller 19 is provided to prevent sagging and derailment of the wire rope 10.

In this configuration, as described in (a) of FIG. 3, the rotational force of the motor 8 is transmitted to the reducer 9 through the belt 13 and then decelerated appropriately so that the winding drum 11 rotates clockwise. In the state where the wire rope 10 is wound around the winding drum 11 in a large amount, the protection net 3 is lifted up toward the frame 1, and as shown in FIG. When the winding drum 11 starts to rotate counterclockwise by changing the rotation mode, the wire rope 10 wound around the winding drum 11 is guided to the horizontal roller 5 and the vertical roller 6 and gradually drawn out. As the guard net 3 starts to descend, the other end of the rope 15 fixed to the frame is fixed to the upper support 14 of the guard net 3 and the wire rope 10 is fixed to the lower support 15. Upper support 14 at the point when rope 16 is fully extended. ) Stops, and only the lower support (15) continues to fall, so that the protection net (3) is to be unfolded, and if the motor (8) is reversed again, the wire rope (10) is wound, the lower support (15) rises first and the upper The bottom of the support 14 is in contact with the guard net 3 is to be raised at the same time in a fully folded state.

According to this proposal, the protection net is installed while descending from the upper side by the electric driving device, so that the protection net can be installed and reduced quickly without damaging the floor of the gymnasium, and the various facilities and the indoors can be protected. Broadcasting equipment for broadcasting can be protected even in close proximity to the athlete, and the coach or coach can be instructed from the athlete's immediate position and can also be used as a partition to separate the stadiums. In addition, it can increase the concentration of athletes and users, thus improving the performance and providing effective physical activity.
