The receiving cylinder 32 has a cylindrical shape having an inner diameter into which the vertical rod portion 21 can be inserted and having an open upper end. Further, a cutout groove 34 having a width that allows the horizontal rod portion 23 to be inserted therein is formed so as to extend in the vertical direction from the upper end of the receiving cylinder 32 to the protruding position of the locking piece 33. The locking piece 33 is made of a member having a substantially semi-cylindrical cross section, the inner surface of which is formed into a curved surface that substantially matches the outer peripheral surface of the horizontal rod portion 23, and is fixed to the receiving tube 32 with the inner surface facing upward. As described above, when the vertical rod portion 21 is inserted into the receiving cylinder 32 from the lower end side thereof as shown in FIG. 6A, the vertical rod portion 21 is held by the receiving cylinder 32 as shown in FIG. The rod portion 23 is placed on the locking piece 33, and the engagement between the locking piece 33 and the horizontal rod portion 23 prevents relative rotation between the frame body 2 (divided frame body 2a) and the support member 3a. It has become so.
The supporting member 3b on the right side when viewed from the front is formed symmetrically with the supporting member 3a.

The knitted fabric 4 is knitted using a plurality of types of knitting yarns having different colors. In this embodiment, as the knitting yarn, two types of monofilament yarn made of polyethylene, blue and white, are used. Then, the two types of knitting yarns are respectively set in the yarn feeder of a flat knitting machine (not shown), intarsia knitting or the like is performed, and the knitting yarns appearing on the knitted fabric surface in the knitting process are switched,
A pattern 41 is formed on the surface of the knitted fabric 4. More specifically, this design 41 has a shape in which the numbers "1" to "5" are surrounded by circles, and the white knitting yarn is knitted in the area within the circle which is the background of each number. It appears on the surface of No. 4, and the area is white. On the other hand, in the area indicating the numeral itself and the area outside each circle, the blue knitting yarn appears on the surface of the knitted fabric 4, and these areas exhibit blue color. Each symbol 41 configured as described above,
This is a target of the ball when the practitioner performs the practice of hitting the soccer ball against the knitted fabric 4. Also, knitted fabric 4
Has a relatively open-mesh net structure for good ventilation.

Around the knitted fabric 4, a reinforcing band 42 of a predetermined width made of cloth, a synthetic resin sheet or the like is integrally provided, and a plurality of eyelets 4 are provided at appropriate intervals on the reinforcing band 42.
3 (see FIG. 3) are provided. And each eyelet 4
Mounting band 4 made of synthetic resin or the like inserted through the center hole of 3
The reinforcement belt 42 and the frame body 2 are connected by 4, so that the knitted fabric 4 is supported inside the frame body 2 while being pulled outward with some tension.

FIG. 1 and FIG. 3 show how the ball practice tool 1 is used. In this state, since the upper and lower tubular members 50 are in the "hinge portion rotation restricting position" for accommodating the divided end portions 2a1 and 2b1 of the divided frame bodies 2a and 2b, respectively, they are connected by the hinge portion 25. Horizontal rods 22 and 22
And 23, 23 are held in a straight line, and rotation of the hinge portion 25 is restricted. Therefore, the frame body 2 is held in a state of being expanded in a plane. Further, as shown in FIG. 3, one end portion of the hinge plate 26 that constitutes the hinge portion 25 has a tubular member 50.
Of the hinge plate 26.
Of the cylindrical member 50 is prevented from rotating around the cylinder center. Therefore, the tubular member 50 will have a “hinge rotation allowance position”, which will be described later, due to vibration or the like when the ball hits.
It doesn't move carelessly.

When the ball practice tool 1 is folded for transportation, the frame 2 is lifted and the vertical rod 21 is pulled out from the receiving tube 32 of the support members 3a and 3b. While removing 3b, the frame body 2 is folded in two as follows. That is, FIG.
From this state, the operation lever 55 is operated to move the tubular member 50 rightward toward the paper surface of FIG. 3 to bring the hinge plate 26 out of the engaging recess 54 into the state of FIG. 4A. Next, the operation lever 55, which is diagonally downward, is pushed upward so that the operation lever 55 becomes substantially horizontal.
The tubular member 50 is rotated to the state of (b). And
From the state of FIG. 4B, a force to the left toward the paper surface is applied to the operation lever 55 this time, and the hinge portion 25 passes through the groove portion 52 and goes out of the tubular member 50. Until the tubular member 50 is moved. In FIG. 4 (c),
Since the tubular member 50 is located at the “hinge rotation permitting position” in which the opposing divided ends 2a1 and 2b1 of the divided frames 2a and 2b have come out of the cylinder, the tubular member 50 allows the hinge portion 2 to move.
The rotation of 5 is not restricted. Therefore, from this state, the frame body 2 can be folded into the two-fold state shown in FIG. 7.

The ball practice tool 1 is configured as described above, and when not in use, the frame 2 and the support member 3 as shown in FIG.
The frame body 2 can be folded compactly while being divided into a and 3b. Therefore, it can be stored in the trunk of a general passenger car and transported from the storage location to the practice location and from the practice location to the storage location. Since there is no need for the like, there is an advantage that the transportation is easy.
Further, when practicing using the ball game practice tool 1, since the rotation of the hinge portion 25 can be regulated by the tubular member 50 (rotation regulation means), the frame body 2 will be damaged by the impact of a ball hit or the like. It is possible to prevent a bent state.

Further, for example, if the bounce-back means is composed of a plate-shaped member, a large impact sound is generated each time the ball hits, so if it is used in a park or vacant lot near a private house, it will be a nuisance to the neighborhood. Especially when practicing at night or in the early morning, it is difficult to find a place to practice. On the other hand, in the ball game practice tool 1, since the knitted fabric 4 is used as the rebounding means, and the impact sound at the time of a ball collision is hardly generated, it is hard to be restricted by the practice place and the practice time, and the practice can be performed anytime, anywhere. It becomes possible to do. In addition, the elasticity of the knitted fabric 4 causes the ball to bounce back vigorously, so that the practice effect is improved as compared to the conventional practice.

Further, for example, when the target pattern of the ball is formed by printing or painting, the color may be discolored to make the pattern unclear when used for a long period of time, or the ball may have paint or ink. The defect that color adheres occurs. On the other hand, in this ball-playing practice tool 1, since the pattern 41 is formed by knitting knitting yarns of different colors,
There is no discoloration or adhesion of color to the ball and it can be used suitably for a long period of time.

Further, in this embodiment, since the knitted fabric 4 is knitted with the yarn made of polyethylene, when the knitted fabric 4 becomes dirty, it can be easily washed by washing with water and is unnecessary due to damage or the like. Even if the knitted fabric 4 is burned, there is an advantage that no toxic gas is generated. In addition, since the knitted fabric 4 is knitted in the shape of a net having coarse meshes and has good air permeability, there is an advantage that it is possible to prevent the accident in which the ball training equipment 1 falls due to wind pressure as much as possible.

FIG. 8 shows a ball practice tool 1A according to another embodiment of the present invention. In this ball game practice tool 1A, instead of the knitted fabric 4, a wire netting 60 (bounce means) made of a plurality of steel wires arranged vertically and horizontally at appropriate intervals is provided inside the frame body 2. In addition, the metal net 60 has a total of five circular holes 61 each having a diameter larger than that of a soccer ball, and inside the holes 61, a sheet in which numbers "1" to "5" are displayed respectively. The body 62 is suspended via a suspending tool such as a string or a chain. Further, each of the divided frame bodies 2a and 2b is provided with a support member mounting portion 63, and two front and rear support members 64 are detachably attached to each support member mounting portion 63. Each support member 64 is formed in a substantially bent shape near the base end portion, and the base end portion is inserted into the insertion hole of the support member attachment portion 63 and screwed into the support member attachment portion 63 from above. It is fixed by a lock screw 65.

Although not shown in detail, the hinge portion, the tubular member 50 and the like have the same structure as that of the ball practice tool 1. In addition, the wire netting 60 has an upper end and a lower end that divide the frame body 2.
It is divided into left and right by a pair of partition bars 66a and 66b fixed to the positions near the divided ends of a and 2b, respectively, so that relative rotation of the divided frame bodies 2a and 2b around the hinge portion is not hindered. It is configured.

In the ball game practice tool 1A, when the practitioner kicks the ball aiming at any one of the holes 61, the ball passes through the hole 61 and the wire net 60 only when the player kicks the ball in the intended direction. To the back side of. Therefore, the practice of improving the accuracy of passing and shooting can be efficiently performed.

The ball game practice tool according to the present invention is not limited to the above-described embodiment. For example, in the above description, the frame body is composed of a divided frame body that is divided along the vertical dividing line x. It is also possible to divide the body into a plurality of dividing frame bodies each having a shape obtained by dividing the body along a horizontal dividing line. However, since this kind of ball game practice tool is often formed in a slightly oblong rectangular shape, it is more compact to fold it along the vertical dividing line to make the dimension (length) in the folded state more compact. It is possible and preferable. Further, in the above description, the frame body is divided into two, but it is conceivable that the frame body is composed of three or more divided frame bodies.

Further, although the engaging means of the tubular member 50 is constituted by the engaging convex portion 53 and the engaging concave portion 54 in the above, the engaging means prevents the tubular member 50 from being inadvertently displaced. Any specific configuration may be used as long as it can do so. Furthermore, the rotation restricting means of the hinge portion is not limited to the tubular member. However, it is preferable to use the tubular member as the rotation restricting means from the viewpoint that the rotation of the hinge portion can be surely restricted with a simple structure and the operation is easy.

Further, when the bounce means is constituted by a knitted fabric, the pattern formed on the knitted fabric is not limited to the above-described one, and for example, the knitted fabric is divided into a plurality of vertical and horizontal lines arranged in a lattice pattern, It is also conceivable to adopt a design in which each section is targeted by the ball.

[0030]

As described above, according to the ball-playing practice tool of the present invention, the frame can be folded compactly when not in use. Therefore, the frame can be stored in a trunk of a general passenger car for transportation. Since there is no need for a truck or a wagon for transporting unlike the conventional ball training equipment, it is easy to transport.

Further, in the case where the rotation restricting means is made of a cylindrical member, the effect that the rotation of the hinge portion can be surely restricted with a simple structure and the operation is easy is obtained.

Further, in the case where the bounce-back means is composed of a knitted fabric made of knitting yarns of different colors, almost no impact noise is generated at the time of a ball collision, and the color is discolored to make the pattern unclear. The effect that the color does not adhere to the ball and the ball can be suitably used for a long time is obtained.
