Description

shoot practice device

The present invention relates to a shooting practice device.

In a basketball game, a basketball machine (also called a shooting machine) collects the ball shot toward the goal with a net and passes the ball to the practicer so that the practicer can continue shooting practice. ) is known (see, for example, Patent Document 1). In the basketball machine of Patent Literature 1, the ball collected by the net is ejected toward the front of the player by a pair of passing rollers provided above and below the tip of the ejection port.

Each of the pair of passing rollers is driven by a motor, and in order to apply reverse rotation (backspin) to the ball, the upper passing roller is controlled to rotate more slowly than the lower passing roller. be. Giving this reverse spin to the ball reproduces the chest pass, which is one of the pass plays typically performed in basketball. This is to allow the ball to reach the player who is relatively far away from the ball in a straight line and speedily as much as possible.

In addition to basketball machines, pitching machines for baseball, for example, are well known as machines that impart spin to the ejected ball. Pitching machines have an arm type that simulates the pitcher's arm as a mechanism for ejecting the ball, and a roller type that uses a pair or three or more rotating rollers (rotor type, wheel type) similar to the above basketball machine. ) are often used. While the arm type is limited to straight pitches, the roller type is capable of throwing a variety of breaking balls.

In addition, in recent years, an air type (air gun type) pitching machine that uses compressed air to shoot a ball has been disclosed (see Patent Document 2, for example). In the pitching machine of Patent Literature 2, the ball is non-rotating when it is injected with compressed air, and the trajectory of the ball in the air becomes irregular. A rotating body driven by a motor and a pressing body for pressing the ball at a position facing the rotating body are provided as a ball rotating means for rotating the ball. Basketball and baseball have different ball structures, and the speed and flight distance imparted to each ball are also different. Both the passing roller and the rotating body are common in that they are driven by a motor.

U.S. Pat. No. 5,776,018 JP 2019-080684 A

However, in the basketball machine disclosed in Patent Document 1, the ball is ejected by a pair of passing rollers driven by a motor, and in the pitching machine disclosed in Patent Document 2, the ball is ejected in an air gun manner. There is a problem that it is difficult to learn the timing in the actual play of receiving a pass and shooting while observing its movement. In addition, since both

In the following description, the front side of the goal 4 is called the front, the back side of the goal 4 is called the rear, the right side as seen from the goal 4 is called the right side, and the left side as seen from the goal 4 is called the left side. Further, in the following description, a plurality of identical members are individually assigned reference numerals with branch numbers.

The gist of the shooting practice device 100 is as follows. That is, the shooting practice device 100 includes a base 1, a ball ejection unit 2 that is provided in front of the base 1 and ejects a ball toward the practicer, and a ball ejection unit 2 that is provided in front and above the ball ejection unit 2 to shoot the ball. and a rotating roller 5 for imparting reverse rotation to the ball by coming into contact with the upper end of the ball. The ball shooting unit 2 has an arm 22 whose lower part is rotatably supported by the base 1 and whose upper part shoots a ball. The rotating roller is non-powered.

It should be noted that the shooting practice device 100 is not limited to basketball shooting practice, but can also be applied to shooting practice in other ball games derived from or similar to basketball. Other ball games include, for example, beach basketball, netball, korfball, which have a basket or cage goal at a high post like basketball but do not have a backboard to bounce the shot ball. Sestoball and the like can be mentioned. Below, the shooting practice device 100 will be described by taking a case of applying it to basketball as an example.

(Overview of shooting practice device)
First, with reference to FIGS. 1 to 3, an overall outline of an example of a basketball shooting practice device 100 will be described. The shooting practice device 100 includes a base 1, a ball ejection section 2 provided in front of the base 1 and ejecting a ball toward the practicer, and a ball shot by the practicer provided behind the base 1. A net supporting part 3 supporting a net supporting part 31 on which a net 32 for recovering is suspended, and a goal supporting part 41 detachably erected on the base 1 or the net supporting part 3, and a goal for a practice player to shoot a ball. 4 and .

The base 1 is for mounting the ball shooting part 2, the net support part 3, and the goal 4. Casters 11 (front left caster 11a, rear left caster 11b, front right caster 11c, rear right caster) 1 and 3 for

casters

11a and 11b, FIG. 3 for caster 11d, and FIG. 4 described later for caster 11c. As a result, the shooting practice device 100 can be freely moved to a desired place where it can be arranged. When the casters 11 are provided, the shooting practice device 100 can be fixed by providing a stopper (not shown) on one of the casters 11, for example, the rear left caster 11b and the rear right caster 11d. can be

The ball ejection part 2 is provided in front of the base 1 and has an opening 21 that opens forward. When a ball is thrown into the opening 21 in a manner to be described later, the ball is shot forward by an arm 22 as a shooting mechanism provided inside the ball shooting section 2 . The practice person receives the shot balls as a pass, and when the balls are shot continuously, the practice person can practice shooting continuously accordingly. As will be described later in detail, above the opening 21, there is provided a rotating roller 5 to which the ball ejected by the arm 22 comes into contact and is imparted with reverse rotation.

The net supporting portion 3 is provided behind the base 1, and includes net supports 31 (a net support 31a on the front left, a net support 31b on the rear left, a net support 31c on the front right, and a net support 31d on the rear right). ) and the net 32 suspended from the net post 31 (the front is net 32a, the rear is net 32b, the left is net 32c, and the right is net 32d). The net supporting portion 3 has an upper portion that is longer forward than a lower portion in a side view, considering the inclination of the net supports 31a and 31c when the net 32 is expanded (see FIG. 7 described later).

Since the shoot practice device 100 for basketball is described here as an example, the net supports 31 are all deployed in front of the goal 4, and the net 32 covers the front of the goal 4 on four sides to recover the ball. is formed to A rear net 32b located in the immediate vicinity of the goal 4 is set lower than the

other nets

32a, 32c, 32d in accordance with the height of the goal 4. - 特許庁

In the case of the shooting practice device 100 related to the goal 4 without the backboard 42, such as beach basketball, netball, korfball, and sestball, in these ball games, a shot can be taken from anywhere within 360 degrees around the goal 4. Therefore, for example, by expanding the base 1 and providing a net support part 3 behind the goal 4, the goal 4 is sandwiched between the two net support parts 3, and the 360-degree circumference of the goal 4 is covered by the net. 32 may be covered.

The net struts 31 protrude upward through through holes 37 of the top plate 36 of the net support portion 3 . The lower end of the net support 31 is supported by a pedestal 39 (see FIGS. 7 to 9) arranged inside the net support portion 3, as will be described later. It is preferable that the net post 31 be telescopic in consideration of the storability in the net support portion 3 . Here, as an example, a three-stage telescopic net strut 31 of upper/middle/lower stage is shown, and one net strut 31 is provided with two stretchable portions 38 . When the telescoping portion 38 is relaxed, the upper section is accommodated in the middle section and the middle section is accommodated in the lower section.

A net attachment rim 33 is erected in front of the top plate 36 of the net support portion 3, and the bottom of the net 32 is attached to the net attachment rim 33 so as to surround it from all sides. The ball collected by the net 32 comes out from the net mounting rim 33, passes through the ball guiding portion 34, and is thrown into the opening portion 21 of the ball shooting portion 2 described above.

The goal 4 includes a goal post 41 (goal post 41a on the left side and goal post 41b on the right side), a backboard 42 attached to the top of the goal post 41, and a goal ring 43 attached to the front of the backboard 42. Prepare. The goal post 41 is erected on the net support portion 3 and supports the goal 4 as will be described later. Instead of the left goal post 41a and the right goal post 41b, a single structure or a three structure may be used.

A basket through which the ball passes is attached to the goal ring 43, but the illustration is omitted here. As for the baskets, in addition to basketballs, beach basketballs, netballs, korfballs, sesteballs, and the like, which are suitable for each ball game, are attached. Depending on the ball game, a basket or cage with no hole in the bottom is used. A basket or cage with holes in the bottom may be attached for practice.

In the case of the shooting practice device 100 related to the goal 4 without the backboard 42, such as beach basketball, netball, korfball, and sestball, the goal link 4 (and the omitted basket or cage) is attached to the goal post 41. Attached to the top (or top edge).

(Ball ejection part)
Next, the ball ejection section 2 will be further described with reference to FIG. FIG. 4 shows a state in which the net 32 has been removed and the outer shell of the base 1 and the top plate 36 of the net support portion 3 have been removed for the sake of explanation.

The ball ejection section 2 functions as follows. First, the ball collected via the net attachment rim 33 falls along the downwardly curved ball guiding portion 34 and is temporarily dropped at the bent portion 34a that bends just before the opening 21 of the ball ejection portion 2. Acceptable. As a result, the falling ball, whose momentum has been reduced, rolls on the slope of the lower end of the bent portion 34a, is guided by the guides 23 (horizontal guide 23a, vertical guide 23b), and is thrown into the opening 21. FIG. A thrown ball is supported by an arm 22 as a shooting mechanism provided inside the opening 21, and the arm 22 shoots the ball forward from the opening 21 by means of a spring mechanism (not shown). The manner in which the balls contact the rotating roller 5 and are ejected will be described later with reference to FIGS. 5 to 7. FIG.

The ball ejection unit 2 may be mechanically driven or electrically driven. Also, the direction of ejection of the ball, the ejection speed, the ejection interval, etc. may be controlled to arbitrary settings. With respect to the shooting direction, for example, in the case of basketball, the ball ejection unit 3 may be rotated within a range of 180 degrees in front of the goal 4. In the case of beach basketball, etc. 1 may be expanded so that the ball launcher 3 rotates in a range of 360 degrees around the goal 4. FIG.

(Rotating roller)
A manner in which the balls contact the rotating roller 5 and are ejected from the ball ejector 2 will be described with reference to FIGS. 5 to 7. FIG. 5 and 6 illustrate the inside of the ball ejection section 2 with the cover removed. As described above, the collected ball falls along the ball guiding portion 34 and is once received by the bent portion 34a that bends just before the opening 21 of the ball ejection portion 2. , and guided by the guides 23 (horizontal guide 23a, vertical guide 23b) and thrown into the opening 21. As shown in FIG. The balls are held in horizontal guides 23a.

A spring (not shown) is connected to the lower part 22b of the arm 22 and extends to the rear of the Bose injection unit 2. A supporting member 22c connected to the upper part 22a of the arm 22 pulls the upper part 22a downward and rearward. Then, the lower portion 22b of the arm 22 is pulled forward and upward against the spring, and the spring extends. Then, when the support member 22c releases the pull-down of the upper portion 22a, the spring contracts and the upper portion 22a and the lower portion 22b of the arm 22 return to their original positions. The contracting force of this spring propels the ball forward.

Here, the upper portion 22a of the arm 22 may eject the ball while in contact with the ball, or may eject the ball while separated from the ball. Furthermore, in order to increase the ejection force applied to the ball in the ejection direction, a protrusion (not shown) is provided on the upper portion 22a of the arm 22, and the upper portion 22a is pulled down until the protrusion is separated from the ball, and the ball is moved horizontally. The ball held by the guide 23a may be hit by the protrusion.

Alternatively, the support 22c may be driven by a motor (not shown), which may operate periodically at regular time intervals or may be weighted by one or more balls. You may make it operate|move according to.

The upper end of the ball ejected in this manner contacts the rotating roller 5 provided on the upper front side of the ball ejecting section 2 . The ball is rotated in the opposite direction to the injection direction by the force applied by the arm 22 in the injection direction and the impact of contact with the rotating roller 5 .

The rotating roller 5 can be configured in various ways. In FIGS. 5 and 6, a roller supporting portion 52 extending forward and upward from the upper portion of the frame material constituting the ball ejecting portion 2 and a An example configured by a rotatably mounted roller body 51 is shown. The roller body 51 is freely rotated by the contacting balls and is not rotated by a motor. That is, the roller main body 51 and the rotating roller 5 are non-powered.

The degree of reverse rotation (number of rotations, rotation speed) and flight distance of the ejected ball can be adjusted by the degree of contact between the rotating roller 5 and the ball. For example, when the ejection force of the arm 22 is the same, the angle of the roller support portion 52 is adjusted to the acute angle side with respect to the ejection direction, and the roller main body 51 strongly hits the ball, thereby increasing the degree of reverse rotation and flying the ball. You can also extend the distance. On the other hand, by adjusting the angle of the roller support portion 52 to the obtuse side with respect to the ejection direction and making the roller body 51 slightly contact the ball, the degree of reverse rotation can be weakened and the flying distance can be shortened.

Furthermore, the rotating roller 5 may be modified in various ways depending on the content of shooting practice. For example, the roller body 51 may be provided with a stopper (not shown) to prevent the roller body 51 from rotating. When the roller body 51 does not rotate, the ejected ball contacts the reverse roller body 51 and rotates in the reverse direction, but the flight distance can be shortened. Further, if it is desired to be able to practice against a non-rotating ball, the roller support portion 52 may be made foldable or extendable so that the roller main body 51 does not come into contact with the ball.

FIG. 7 is an enlarged side view of part of FIG. 4 and schematically shows how the ball B flies. The ball B ejected by the arm 22 from the ball ejection part 2 is imparted with reverse rotation by coming into contact with the rotating roller 5, and flies toward the trainee P. Due to the lift force (Magnus effect) generated by the reverse rotation, the ball B reaches the ball B as linearly and speedily as possible against gravity. If the degree of reverse rotation is weak or if there is no rotation, the flight distance of the ball B becomes short, and the ball B falls toward the floor in front of the practicer.

(Net support part)
Returning to FIG. 4, the net supporting portion 3 will be described. The net supporting portion 3 supports four net supports 31. In this case, the expandable portions 38 (see FIG. 1) of the net supports 31 are relaxed to shorten the upper/middle/lower portions. Shown in the closed state. The net supports 31a and 31b of the net supports 31 are stored in a state in which the lower part containing the upper/middle part is dropped into the lower part of the net support 3, while the net supports 31c and 31d are stored. , the lower part accommodating the upper/middle part is supported by a pedestal 39 (described later with reference to FIGS. 7 to 9) provided at a predetermined position inside the net support part 3. , respectively. The net struts 31 take the positions of the

net struts

31a and 31b when stored in the net supporting portion 3, and the positions of the

net struts

31c and 31d when the net 32 is stretched.

Next, how the goal 4 is attached to the net support portion 3 will be described with reference to FIGS. 7 to 9. FIG. 8 and 9 show a case where FIG. 4 is viewed from the rear.

As shown in FIG. 8, both the left goal post 41a and the right goal post 41b of the goal 4 have upper and lower connecting portions 35 (lower connecting portions 35a , and the upper connection portion 35b). Specifically, the net supporting portion 3 has a lower connection portion 35a and an upper connection portion 35b for attaching the goal post 41 to the back surface 351 thereof, and the lower portion of the goal post 41 is pivotally attached to the lower connection portion 35a. A corresponding portion of the goal post 41 is attached to the upper connecting portion 35b. A fixing means such as a wing bolt is used for axial attachment or fastening of the goal post 41 .

As for the mounting procedure of the goal post 41, as shown in FIG. 9, first, with the goal 4 laid down, the lower part of the goal post 41 is rotatably pivoted to the lower connecting portion 35a. Then, after the goal 4 is raised, the corresponding portion of the goal post 41 is fixed to the upper connecting portion 35b. FIG. 7 shows a state in which the goal post 41 is erected on the back surface 351 of the net support portion 3. As shown in FIG. When removing the goal 4, conversely, after removing the goal post 41 from the upper connection portion 35b, the lower part of the goal post 41 is removed from the lower connection portion 35a with the goal 4 laid down.

In this way, by rotatably attaching the lower part of the goal post 41, the goal 4 can be attached to or removed from the net support part 3 in a state of being laid down, so that the attachment work can be performed easily. Even if there is only one person, the goal 4 can be erected or dismantled on the back surface 351 of the net support part 3 safely and without difficulty.

In this embodiment, the goal post 41 is detachably erected on the outside of the back surface 351 of the net support portion 3. Alternatively, the goal post 41 may be placed on the back surface 351 of the net support portion 3. It may be erected inside, on the upper surface (top plate 37) or side surface of the net support portion 3, or on the base 1 in a detachable manner. Among these, when standing on the upper surface of the net support portion 3, for example, the upper connecting portion 35b that can be rotated is provided on the upper surface, and the goal post 41 is axially attached. may be applied. Moreover, when standingly installed on the base 1 , the lower connection portion 35 a may be provided on the base 1 and the upper connection portion 35 b may be provided on the net support portion 3 . In this manner, the lower connection portion 35a and/or the upper connection portion 35b can be appropriately set according to the placement location of the goal post 41. FIG.

Here, in FIGS. 7 to 9, unlike FIG. 3, casters 45 (casters 45a on the left goal post 41a and casters 45b on the right goal post 41b) are provided at the lower end of the goal post 41 or the lower connection portion 35a. It shows how it is provided. When the weight of the goal 4 increases due to the material of the goal 4, the weight of the goal 4 is transmitted to the floor surface by providing the casters 45, thereby lightening the load on the net support portion 3. Also, the effect of increasing the stability when moving the shooting practice device 100 can be expected. In addition, it is also possible to previously attach the casters 45 to the goal post 41 so as to be rotatable. It can be easily transported by a person.

A supplementary note about the pedestal 39 mentioned above. As shown in FIGS. 8 and 9, inside the net supporting portion 3, a pedestal 39 is provided for supporting the net support 41 at a position where a desired height of the net support 41 can be obtained. When viewed from the side of the net support portion 3, it is as shown in FIG. support the bottom edge of the In FIG. 7 , as in FIGS. 8 and 9 , the net supports 31 a and 31 b are stored in a state in which the lower part containing the upper/middle part is dropped into the lower part of the net supporting part 3 . , the net struts 31c and 31d are shown in a state in which the lower part containing the upper/middle part is supported by the pedestal 39. As shown in FIG.

Next, the folding structure of the net struts 41 will be described with reference to FIG. FIG. 10 shows a case where the net struts 41 are folded backward in the mode of FIG.

The goal post 41 has a folded portion 44 (folded portion 44a on the left goal post 41a and right goal post 41b) at a position above the top plate 36 of the net support portion 3 when standing on the net support portion 3. has a folding portion 44b). The folding part 44 has a hinge structure and is provided with a stopper to prevent unintended folding. When necessary, the stopper can be released to fold the goal post 41 backward. Maintenance management such as storage and transportation of a certain place can be easily performed.

Furthermore, although FIG. 10 shows a mode in which the goal strut 41 is folded once backward, another folding portion is provided between the folding portion 44 and the backboard 42 to further fold the backboard 4 forward. You may do so. By folding the goal post 41 in a Z shape in this manner, the storage and transportation of the shooting practice device 100 can be facilitated even with the goal 4 attached.

(Other aspects of the shooting practice device)
As described above, the shooting practice device 100 can also be applied to similar ball games other than basketball, such as beach basketball, netball, korfball, sesteball, etc., in which a goal 4 without a backboard 42 is set. can be done. In these ball games, it is possible to shoot from anywhere within 360 degrees around the goal 4. Therefore, in the above explanation, the base 1 of the shooting practice device 100 is expanded to cover the net behind the goal 4 as well. It has been described that by providing the support part 3, the goal 4 may be sandwiched between the two net support parts 3 so that the net 32 covers 360 degrees around the goal 4. The goal 4 may be surrounded by a relatively large net support portion 3 . In this alternative embodiment, for example, the goal post 41 of the goal 4 is similarly erected on the base 1 or the net support portion 3, and the goal post 41 is arranged so as to pass through the net mounting rim 33. , the net 32 on the four sides surrounds the entire circumference of the goal 4 to recover the ball.

In addition, the shooting practice device 100 may be configured so that the height of the goal 4 (goal ring 43) can be adjusted so that not only advanced players but also beginners and children can practice shooting. . For example, all or part of the upper portion of the goal post 41 may be telescopic like the net post 31 . In this case, the length and angle of the net support 31 are adjusted so that the height of the upper side of the stretched net 32 is harmonized with the height of the goal 4 (goal ring 43). If the goal post 41 is of a telescopic type, it can be easily stored and transported in places with height restrictions even when not in use.

(Effect of Embodiment)
In the present embodiment, as described above, the shooting practice device 100 includes a base 1, a ball ejection section 2 provided in front of the base 1 and ejecting a ball toward a practicer, and a ball ejection section 2. A rotating roller 5 is provided on the front upper side and contacts the upper end of the ejected ball to impart reverse rotation to the ball. The ball shooting unit 2 has an arm 22 whose lower part is rotatably supported by the base 1 and whose upper part shoots a ball. The rotating roller is non-powered. As a result, the ball ejection unit 2 can impart reverse rotation to the ball as desired, even if it is an arm-type ejection using a spring. As a result, it is possible to provide the shooting practice device 100 that reproduces the reverse rotation of the ball in an actual pass play without pressing the ball, and that enables the practicer to easily learn the timing from receiving to shooting. Specifically, the practicer takes a posture and moves in accordance with the timing of the movement of the arm 22, and receives the ball rotating in the opposite direction in the same way as a chest pass in an actual game. You can practice shooting.

Further, the shooting practice device 100 includes a net supporting portion 3 which is provided behind the base 1 and supports a net pillar 31 on which a net 32 for recovering the ball shot by the practicer is suspended, and the base 1 or the net. A goal post 41 is detachably erected on the support part 3, and the goal 4 for a practicer to shoot a ball is provided. In addition, it is possible to provide the shooting practice device 100 that enables shooting practice against the goal 4 of the basket or cage with or without the backboard 42 .
