In addition, one ceiling ball passage prevention surface with a synthetic resin net as a ceiling ball passage prevention frame and two vertical ball passage prevention surfaces facing the ball passage prevention surface prevent the passage of ceiling balls. It is a frame surface for preventing the passage of two opposing balls with a synthetic resin net as a frame.

The horizontal frame has four lower positions at positions of 10 to 30 mm, four upper positions of 2 m or more, and four vertical frames. However, in the case of carrying out the present invention, the horizontal frame is used. And one ball collision surface having the ball net receiving surface may be one that cuts four lower positions and four upper positions with a length of 1/2.

One ball collision surface is adjacent to the two ball passage prevention surfaces on both sides, and a receiving hole of a single or triple ball net receiving surface is formed at an appropriate height position. In particular, on one ball collision surface, the high-speed ball rapidly decelerates due to the contact pressure of the ball.
Further, the open surface on which the ball passage prevention frame surface is not stretched is a surface having no ball passage prevention frame surface formed at a position facing one ball collision surface.

In addition, the raindrop preventive device that makes it difficult for batting practitioners to receive rainwater is a synthetic resin sheet laid on the lower side of the ceiling ball passage prevention frame surface so that it is difficult for rainwater to be applied. ..
The synthetic resin sheet is, for example, a synthetic resin sheet made of polyethylene, which is commonly called a "blue sheet (regardless of color)" or the like.

The ball passage prevention frame is composed of four surfaces, a ceiling ball passage prevention frame composed of one surface, a ball passage prevention frame composed of two surfaces, and a ball collision frame having a ball collision surface composed of one surface.

The space surrounded by the frames on the four sides is called the ball collision surface in the sense that it is surrounded by the four frames.

Is composed of one or two sheets, and at least the sheet laid on the upper surface is laid on the upper side of one ceiling ball passage prevention frame surface 26, and the flow of rainwater passes through the ceiling ball on the lower surface side. It is designed so that it does not face the lower surface of the prevention frame surface 26.

In FIG. 9, one ceiling ball passage prevention frame surface means that the ball passage prevention synthetic resin net is functioning. A metal lath net E (or punching metal) is laid on the upper surface of the ball passage prevention frame N and the ball passage prevention frame surface, which forms the lowermost portion. The uppermost part is a synthetic resin plate M such as Styrofoam, and a water channel through which rainwater flows is formed on the upper surface.
The ball passage prevention frame N, the metal lath net E (or punching metal), and the synthetic resin plate M are, for example, synthetic resins made of polyethylene, and are commonly called "blue sheets (distributed regardless of color)" or the like. It is a thing. As this synthetic resin agent, tent land can also be used. Further, the use is not limited to the synthetic resin agent, and any one type of synthetic resin, synthetic rubber, and elastomer may be used.

Alternatively, it can be configured as shown in FIG. One ceiling ball passage prevention frame surface forms the lowermost portion, and a synthetic resin plate M such as styrofoam is formed on the upper surface of the ball passage prevention frame surface, and a water channel through which rainwater flows is formed on the upper surface.
In these synthetic resin sheets M such as Styrofoam, a water channel through which rainwater flows is formed on the upper surface.
At this time, one ceiling ball passage prevention frame surface 26 is a synthetic resin sheet M, and a metal lath net E (or punching metal) through which rainwater flows on the upper surface, or a metal lath on the upper surface of the surface of the ball passage prevention synthetic resin net. The strength is maintained by the net E or the punching metal, and the strength is maintained by the synthetic resin sheet M or the punching metal.

As shown in FIG. 9, when three types of ball passage prevention frame surfaces of one ceiling ball passage prevention frame surface 26, a synthetic resin plate M, and a metal lath net E (or punching metal) are used, one sheet is used. The order of the ceiling ball passage prevention frame surface N, the synthetic resin plate M, and the metal lath net E can be arbitrarily changed.

It is something to do.

In the all-weather batting practice machine of the present invention, rainwater is laid on one ceiling ball passage prevention frame surface 26 and rainwater is collected on the two ball passage prevention frame surfaces 22 and 24, so that rainwater is less likely to fall on the batting practitioner. The raindrop prevention tool 80 is provided with a roof ridge 55 in the center, and a beam 56 provided between the mounting seat 51 and the mounting seat 52 of the roof ridge 55 is provided with a beam 56 in order to have mechanical strength. The lower end is attached to each ball passage prevention frame surface. The beam 56 is parallel to the roof ridge 55, and the roof ridge 55 makes it difficult to bend.
The synthetic resin sheet M can allow wind in five directions to pass through in addition to the all-weather type, and can also create shade and ventilation.

FIG. 12 is basically the same as FIG. 11, but the frame 13 and the frame 15 at the lower end of the synthetic resin plate M as the raindrop prevention tool 80 are prevented from passing through one ball by applying a predetermined tension. Since the frame surfaces 22 and 24 can change the area, they can also have a ratchet function (holding the position where the dead center has passed).

Further, the frame 13a at the lower end of the synthetic resin coat M can be used for the synthetic resin coat M for tension.
In the all-weather batting practice machine of the present invention, a sheet as a raindrop prevention tool 80 that makes it difficult for rainwater to fall on the batting practitioner is placed on the upper surface of the one ceiling ball passage prevention frame surface 26.

In the all-weather batting practice machine of the present invention, the raindrop preventive tool 80 laid on the one ceiling ball passage prevention frame surface to prevent rainwater from falling on the batting practitioner is the ball net receiving surface 30 and one ball collision surface. It has a receiving hole 35 formed by drilling a ball net receiving surface 30 (31, 32, 33) in which notched ends in which a plurality of synthetic resin sheets are arranged are stacked up to a single layer or a triple layer.
The frame 16a of the frame 14a is tensioned by the atmospheric temperature so as not to form a dent.

FIG. 13 shows in the all-weather batting practice machine of the present invention, the raindrop prevention tool 80 is a predetermined square plate sheet 90, and the raindrop prevention tool 80 is attached to two pairs of ball passage prevention frame surfaces 22 and 24 with snap buttons or the like. It is a thing.
As the square plate sheet 90, the square plate sheets 91, 92, 93, 94, 95, 96 made of synthetic resin of the rectangular plate sheet are provided, but the size and the like can be arbitrarily set. Further, the mounting means can be arbitrarily selected, and the size of the square plate sheet 90 (91, 92, 93, 94, 95, 96) can be any size and shape.

In FIG. 13, in the all-weather batting practice machine of the present invention, the rectangular synthetic resin sheet 90 (91, 92, 93, 94, 95, 96) is made of a rectangular foamed synthetic resin, which is a batting practitioner. This is to prevent rainwater from adhering to the area below the waist. The two ball passage prevention frame surfaces 22 facing each other and the ball passage prevention frame surface 24 are positioned low. The roof ridge 55 is attached to the mounting seat 51 or the mounting seat 52 and is easily fixed to the raindrop preventive device 80.

As shown in FIG. 13, the synthetic resin sheet 90 (91, 92, 93, 94, 95, 96) of the rectangular plate sandwiches the synthetic resin frame surface between the male snap button 98, the female snap button 98b, and the belt portion 96. I'm trying to do it.
Therefore, the roof ridge 55 is attached to the mounting seat 51 and the mounting seat 52, and is easily fixed to the raindrop preventive tool 80 by applying tension to the central frame with a nut or the like.

11 and 12 are paints made of synthetic resin, which are doubled with respect to the upper surface of the metal lath net (or punching metal) made of metal, or have a single frame, and the upper surface of the metal with respect to the metal lath net or punching metal. A synthetic resin frame image (foamed synthetic resin sheet) is laid on the floor. As a result, even if a short fly is hit, the rotation of the ball is caused by friction with the metal lath net E or the punching metal, and the hit ball is rapidly lowered.

In FIG. 12, the ratchet mechanism acts on the metal lath net E or the punching metal, and the tension of the foamed synthetic resin sheet can be increased.
In particular, the right side of FIG. 12 becomes high, and the wind can be guided to the foamed synthetic resin sheet to change the flow of the wind.

The casters 1, 2, 3, and 4 are the horizontal frames 5, 6, which fix the both ends of the adjacent horizontal frames 5, 6, 7, and 8 and the lower ends of the vertical frames 9, 10, 11, and 12 extending upward. 7,8 and the vertical frames 5, 6, 7, 8 are independently joined to four or more corners so as to be perpendicular to each other, but the four corners or more so as to be perpendicular to each other are 90 °. Means to get independently.

The two opposing ball passage prevention frame surfaces 22 and 24 with the ball passage prevention frame surface and the one ceiling ball passage prevention frame surface 26 with the ball passage prevention frame surface are carelessly opposed to each other. The ball is prevented from jumping out from one ceiling ball passage prevention frame surface 26 which stretches the ball passage prevention frame surfaces 22 and 24 and the ball passage prevention frame surface.

One ball collision surface 23 adjacent to the two opposing ball passage prevention frame surfaces 22 and 24 and having a single or triple ball net receiving surface 30 and the one ball collision surface 23 facing each other. One open surface 21 formed at the position has a ball net receiving surface 30 in one ball collision surface 23. At this time, the ball net receiving surface 30 has a ball collision surface 23 having a single layer, a double layer, a triple layer, a quadruple layer, and so on.
Here, the ball net receiving surfaces 30 can be stacked in multiple layers, but the single, double, and triple layers are efficient in terms of the efficiency of picking up the balls.

The raindrop preventive tool 80, which is laid on one ceiling ball passage prevention frame surface 26 and has the roof ridge 55, which is difficult for batting practitioners to receive rainwater, is high, and the two ball passage prevention frame surfaces 22, 24 are low, is the roof. Since the building 55 is high and the two ball passage prevention frame surfaces 22 and 24 are low, repair is possible even if the snap button or braid comes off during use.

In addition, although (a), (b) and FIG. 7 of FIG. Either the joining method or the assembling method may be selected.
