Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protective ball support for a hardball baseball to prevent accidents and injuries caused by an irregular and unpredictable hardball ball hitting a protective net support during hardball practice.

  Regardless of professional or amateur, in the case of hardball baseball, we always use a protective net to protect players during training, and we are trying to keep players safe during training, but for professionals, there is a dedicated staff, The number and types of protective nets are abundant, and based on years of experience etc., there are few accidents due to the rebound of hard ball balls, but in the case of flax, there is no dedicated staff and the number of protective nets is small, so hard ball balls The probability of occurrence of accidents and injuries due to bouncing is high, and some of the accidents lead to serious accidents.

  In the case of professionals, there is a dedicated practice area and there is little movement and clearing of protective nets, but in the case of amateurs, the majority, except for some professional baseball, frequently move and clear protective nets, Each time it is installed, it is different every time, and the lack of experience overlaps, and the probability of a hard ball rebounding accident is high.

  The protective nets during hardball practice are not all connected, and cases are different, such as arranging protective nets of the same size or protective nets of different sizes, but basically each is different. Since the work of connecting the defense nets is not performed and the ground is not horizontal, an accident occurs in which a hard ball ball hits a player or the like directly from the gap where the protection nets are lined up.

  Regarding the shape of the protective net support during hardball practice, the diameter varies depending on the purpose and whether or not it moves, but the shape is basically a round pillar. Since the ball is also a sphere, it is impossible to predict the direction and speed of the ball hitting the support, and the speed may be faster depending on the angle of the rebound.

  Patent Literature 1 discloses a hitting practice net in which a space for discharging a tossing ball is provided in a vertically attached central portion of a net, and a hitting target is provided in a batter's side net. .

  Patent Literature 2 discloses a protective fence used in baseball or the like, which includes a stand frame and a rectangular board-shaped cushion pad in order to prevent the ball from bouncing and to prevent irregularities in the direction and variations in the bouncing distance. It has been disclosed.

  Non-Patent Document 1 discloses an improved protective net, which is effective for preventing the ball from bouncing off the ball from the net. The mechanism is to insert the frame into the net to prevent it from bouncing backward. A strut is disclosed.

  The conventional devices disclosed in Patent Literature 1 and Patent Literature 2 cannot be attached to a protective net currently used, and the effects of the tool disclosed in Non-Patent Literature 1 are recognized. No method is disclosed for resolving the problem of ball bouncing or intruding a ball through a gap between nets.

The improved protective net presented in Non-patent Document 1, which is effective in preventing bouncing from a hit ball net, can reduce the impact itself, but cannot predict the direction of the hit ball. Installation is considered economically difficult for amateurs with a small budget.
SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and provides a hard baseball protective net post protection device for preventing accidents and injuries due to irregular and unexpected hard ball balls. The purpose is to:

The protective base support device 4 for a hardball baseball according to the present invention forms a frame by incorporating a rod body in which a reinforcing bar is covered with a tube formed of a flexible material into a fibrous form, and the frame is openable and closable.

  SUMMARY OF THE INVENTION The present invention has an object to prevent a bounce of a protective net support for a rigid baseball and a gap accident. FIG. 1 is a front view in which a protective net post protector 4 is attached to a protective net post via a claw type clamp 3, and a small plan view is also clearly indicated on the upper left. FIG. 2 shows the nail shown in FIG. FIG. 3 is an enlarged plan view in which a protective net post protector 4 is mounted via a mold clamp 3 and clearly shows a case where the protective net post protector 4 is opened. FIG. 3 shows the protective net post 1 shown in FIG. 2 is an enlarged plan view in which the protective net support protector 4 is attached via the claw type clamp 3, and the difference from FIG. 2 is an enlarged plan view when one of the protective net support protectors 4 is short.

As shown in the front view of FIG. 1, since the protective net 2 is wound around the protective net support 1, the clamp 3 is not a normal clamp but a claw type clamp 3 having an open end. In order to attach the protective net support protector 4 to the protective net support 1, it is necessary to use two or more claw-type clamps 3 and attach them, so that a sense of safety and stability is generated.
Further, since the thickness of the protective net support 1 varies depending on the type and purpose of the protective net 2, the protective net 2 and the protective net 2 are sandwiched between the protective net and the support thickness adjuster 8 (eg, urethane-based elastomer). The thickness of the column 1 can be adjusted while preventing the column 1 from being damaged.

As shown in FIGS. 2 and 3, the protection net protector 4 having an elliptical shape is a protection net protection divider 5 and has a structure that is opened by about 360 degrees. You can protect the protection net support 1.
Although an elliptical shape has been described, the shape may be circular or square as long as the shape is cylindrical.

The front view of the batting gauge shown in Fig. 4 with the protective net post protection device 4 attached is considered to be the largest among the protective nets. The height of the front protective net post 1 is 350cm. In this case, it is considered necessary to use two protection net support protectors 4 having a height of 150 cm.
In FIG. 4, the protective net support device 4 is attached only to the front protective net support 1. However, mounting the protective net support device 4 on the lateral or diagonal protective net support 1 helps to improve safety. .

  FIG. 6 is a front view in which two ball-proof double nets are arranged side by side, as shown in FIG. 5, but the baseball ground is usually not flat and has irregularities and gradients. When the pieces are arranged, a gap always occurs and an accident and an injury are caused. However, in the case of the protective net support protector 4, since the cross section is elliptical, the gap of 30 mm to 100 mm or more can be prevented. In this case, it is only necessary that one of the protection net support protectors 4 is long, so the protection net support protector 4 of FIG. 3 is used.

  The front view of FIG. 6, in which the protective net post protection device is attached to the L-shaped pitcher double net, identifies a dangerous place, and the length of the protective net post protector 4 can be any length. It is a diagram showing what can be done.

The protection net support protection device 4 shown in FIG. 7 and the plan view, the side view, and the detailed view show the manufacturing method and structure of the protection net support protection device 4. The diameter of a certain round rebar is based on an outer diameter of 20 mm, and the diameter of a round rebar, which is the core of the inner rubber frame 10 installed inside, is based on an outer diameter of 10 mm and has a length, width, oval shape, etc. After welding, the diameter of the round reinforcing bar 12 which is the core of the large outer rubber frame 9 is 20 mm in outer diameter, and the pipe (large) 11 made of a flexible material (outer diameter 37.5 mm / inner diameter 25.4 mm) Is cut into a single character, and is put on the round reinforcing bar. Similarly, when the outer diameter of the round reinforcing bar 14 which is the core of the inner rubber frame 10 is 10 mm, the pipe (small) 13 (outer diameter 21.9) formed of a flexible material is used. (12.7mm inside diameter).
The size of the square frame of the inner rubber frame is basically 20 mm sq. To 30 mm sq., Assuming that a hard ball is not inserted.
Naturally, the rubber frame is damaged, but the tube made of flexible material is cheap, and even a layman can easily replace it, so there is no running cost.The replacement of the tube made of flexible material was made of damaged flexible material. The tube is removed using a rubber cut for mounting (a straight cut in the length direction), and a tube made of a new flexible material is installed using the cut.
