Description

[Detailed Description of the Invention] This invention is applicable to ball games such as baseball, golf, and tennis! 1・
The present invention relates to a ball batting practice tool used for ball batting practice, and particularly to a practice net in which a net is stretched over a frame member.

In the past, various practice nets have been developed and used as ball batting practice equipment in ball games, but all of them have a simple structure in which a net member is simply fixed to a frame member. Since there is no maintenance adjustment means for tensioning the stretched net in response to loosening of the tension in the net members, maintenance work is troublesome, and it is not possible to obtain a practice net with a tension level suitable for the ball game event. There was a problem.

This invention was made in view of the above circumstances, and allows the degree of tension of the net member stretched over the frame member to be freely adjusted, making maintenance work easier, and also making it possible to adjust the tension to suit the type of ball game exercise. By providing a ball hitting practice tool with a high degree of accuracy, and by connecting a plurality of similarly configured practice nets to each other vertically and horizontally, the practice net can be freely extended in the height and width directions. The purpose of the present invention is to provide a ball batting practice tool.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 indicates the net body, and this net body 1 has an L-shaped upper and lower frame 2a, 2b, and a cloth frame 3' + 3b on the left, which is made of hollow metal pipes, plastic members, etc. A frame member 5 is configured in a rectangular shape with mutual ends connected by a connecting pipe 4. Reference numeral 6 denotes a net member formed by knitting a wire mesh or cotton thread 1 synthetic fiber, etc. On the outer circumferential side of this net member 6, a large number of one ends 7a of elastic bodies 7 such as coil springs are fixedly arranged at predetermined intervals.

Reference numerals 8a and 8b are adjustment rods arranged on the inner surfaces of the upper frame 28 and the cloth frame 3b, respectively.These adjustment rods 8a and 8b
are screwed and locked by bolts 10 that pass through through holes 9 provided from the outer surface to the inner surface of the upper frame 2a and cloth frame 3b, and as the bolts 10 rotate, arrows A and B It is possible to move toward and away from the inner surfaces of the upper frame 2a and cloth frame 3b.

The other end portion 7 of an elastic body 7 has one end portion 7a fixed to the outer peripheral side of the net member 6 on the inner surface of each of the adjusting rods 3a, gb.
latching rings 11 and 12 for latching the elastic body 7 are provided at positions facing the mounting position of the elastic body 7 and spaced apart from each other by a predetermined distance. Similarly, latching rings 13 and 14 for latching the other end 7b of the elastic body 7 are attached to the inner surfaces of the left frame 3a and the lower frame 2b.
.

The net member 6 is stretched around the rectangular frame member 5 by hooking the other end 7b of the elastic body 7 provided on the outer circumferential side of the net member 6 to 13 and 14, respectively. .

In the above embodiment, the upper, lower and left frames.

Although the right frame member is connected by an L-shaped connecting pipe 4 to form a rectangular framework, it is of course possible to form a rectangular frame member by bending a metal pipe.

The embodiment of the present invention constructed as described above has an adjustment rod 8a which is removably locked to the inside of the upper frame 2a + cloth frame 3b of the frame member 5 by means of bolts 10,
gb, and the net member 6 is stretched through the elastic body 7 to the retaining rings 11 and 12 fixed to the inner surfaces of the adjustment rods 8a and 8b. The degree of tension of the net member 6 can be freely adjusted and stretched, and the degree of tension of the net member 6 that has become loose due to use can be repaired.

FIG. 3 shows a second embodiment of the present invention. In FIG. 3, the same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts, and This is a system in which two sets of practice net bodies 1 are connected and have a connecting tool 15 in the height direction. Support legs 16 and 16 are attached to the lower sides of the lower net main body 1 to hold the two sets of net main bodies 1 in an upright state, and a large number of supporting legs 16 and 16 are attached to the lower part of the outer surface of the left and cloth frames 3a and 3b in the vertical direction. An inclination regulating rod 1 which can be fitted into the formed inclination regulating hole 17 and has a pin 18 at one end and whose other end is rotatably connected to the support legs 16, 16.
9 and 19 are attached.

In addition to the effects of the first embodiment, this embodiment with the above configuration has the effect of freely regulating the inclination angle of the entire net body.

FIG. 4 shows a third embodiment of the present invention. In this embodiment, the upper frame 2a and the lower frame 2b of the frame member 5 are
On the other left, the cloth frames 3a and 3b are also formed longer and have a rectangular shape as a whole, and on the sides of the left cloth frames 3a and 3b are support legs 16 and 16 similar to that shown in FIG. It is provided with inclination regulating rods 19, 19 for regulating the angle. In this embodiment, the net members 6 have different shades, and the net members 6a and 6b are of different colors with lJc as the boundary.

In the above embodiment, the color of the net member 6 is different from that of the center part which indicates the height of the net for soccer games etc. Since it is possible to imitate the appropriate net height, a thick net effect can be expected in ball batting practice.

FIG. 5 shows a fourth embodiment of the present invention. In this embodiment, two sets of net bodies 1, 1 are placed on the left, cloth frames 3a, 3b
L-shaped hinge member 20 on the lower outer surface of each
, 20 so that it can be bent at right angles, and the angle of inclination of one of the net main bodies 1 in the upright state can be adjusted freely by the inclination regulating rods 19, 19. In this embodiment, one of the net bodies 1, 1 bent at a right angle is placed horizontally on the ground, and when practicing ball hitting, the other net body 1 is placed upright. This is used for practice by hitting a ball or the like in the direction of the arrow, but since the net body 1 is placed horizontally to the ground, the ball hit against the upright net body 1 bounces back. As the ball falls onto the net member 6 of the net main body 1 which is arranged horizontally, the scattering force of the ball decreases rapidly, which has the effect of preventing the ball from scattering far. can be omitted. Moreover, it goes without saying that this embodiment has the same effects as the first embodiment.

This embodiment is suitable for practice with a golf bat, and in this embodiment, two sets of foldable net bodies 1.1 shown in the fourth embodiment are used with the side frames as the bottom. Both net bodies 1°1 are placed in an upright state, and a triangular protective net 21 is attached above via an elastic body 7'.
Furthermore, a net body 23 having a bee-shaped recess 22 as shown in FIG. 7 is provided near the connection between the net bodies 1 and 1, and the opening is located in the front part between the bottom surfaces. A slanted base board is arranged so that it becomes lower as the height increases.

In this embodiment, a net body n having concave portions n formed in a honeycomb shape is provided, so that when practicing baseball toss batting, for example, the ball is thrown in line with the concave portions 22 and hit, and the ball is placed in the concave portions η. It is possible to store it away,
It is possible to practice hitting the ball according to the target in the recessed part n. In addition, since a slanted base is arranged in the bottom opening, when used for golf putter practice, golf balls that are not stored in the recess 22 will roll down the slope and be hit back many times. It is possible.

As explained above, the ball batting practice tool according to the present invention has adjusting rods that can be moved in and out of the vertical and horizontal frames on each side of the inner surface of the frame member, and that can be moved in and out of the net member by means of bolts. Since it is stretched through an elastic body, it is possible to obtain a practice net with a tension level appropriate for the ball game event, and it is also possible to easily perform maintenance and adjustment work on net members that have loosened due to use. It has various excellent effects.
