Description

  The present invention relates to a badminton target device that allows a badminton player to efficiently perform a practice of hitting a target with a shuttle.

  It is extremely important to practice efficiently in order to drive a shuttle or a ball to a target position (target position) in a sport that handles a shuttle or a ball such as badminton. There are also many training devices developed for this purpose. However, there are many practice exercises aimed at the court line in badminton practice, but no equipment has been developed for that purpose. In actual practice, when a shuttle case or cardboard is used as a target, the practice is to defeat the shuttle case or insert the shuttle into the cardboard. However, in that case, it takes time to return the shuttle case.

  Furthermore, in the case of badminton, there are various hitting methods such as short serve, high clear, drop shot, smash, and drive, and the target position and area size differ depending on those hitting methods. In addition, the drop angle of the shuttle against the court varies for each batting method. Therefore, it is not known whether the shuttle is incident on the target position at an accurate incident angle in a cardboard or shuttle case. In addition, it may be difficult to tell if you are hitting such a target because you may aim at a position far away from the net, such as high clear or smash. There should also be a device to allow children and young people to continue practicing without having to get bored or tired.

  As a conventional technique, Patent Document 1 discloses a tennis training apparatus used for practice of tennis serve or stroke. In particular, this equipment is used as a target when practicing a serve, or as a target for determining the course of a ball, so that it can be used for practicing a serve, a stroke, etc., and can improve the technique. ing. Using this as a target, aim the ball at the opponent's court so that the ball hits the target, or as a goal to determine the course of the ball, aim at the opponent's court so that the ball does not hit the target Type. However, this device is not suitable for practicing aiming near the line. Moreover, since the target is fixed, it cannot respond to various fall trajectories of the badminton shuttle.

  Patent Document 2 discloses a practice tool that can easily perform practice of shooting, passing, etc. alone by receiving soccer centering. It is possible to change the trajectory of the soccer ball that bounces off the ball hitting plate by adjusting the arrangement angle of the ball hitting plate. This practice tool is not a ball target, it is only used to rebound the ball. Therefore, it is not suitable for competition targets that have unique tracks such as badminton shuttles.

  When practicing badminton, it is indispensable to drop the shuttle to the target position on the court. Therefore, I have practiced up to now by setting up a shuttle case and having others see it. However, if you do this, you will have to remake the case every time and take the practice time of others. In addition, it does not support shuttle tracks unique to badminton. Therefore, an object of the present invention is to develop a new practice tool or target that allows badminton practice to be performed efficiently and continuously without getting tired.

  The present invention includes a target frame having a front surface into which a badminton shuttle is driven, a support base that supports the target frame on a floor surface, and a rotation mechanism that can freely change the angle of the front surface of the target frame with respect to the floor surface; A badminton target device having a sensor for detecting that the shuttle has entered the front surface, a notification body attached to the target frame or a support base, and a mechanism for operating the notification body when the sensor detects the shuttle. It is.

  The target device of the present invention has a mechanism in which when the shuttle enters the front surface of the target frame, the sensor detects the shuttle and the notification body notifies the player, so that it can be easily confirmed that the shuttle has hit the target. At the same time, you can feel a sense of accomplishment by hitting. In addition, it is possible to check whether or not the athlete has hit the target by himself without any assistance such as visual recognition by another person or re-installation of the target. Can do. This is especially useful when practicing long serve or short serve alone. In addition, badminton has various techniques, each of which differs depending on the angle of the shuttle that falls with respect to the floor, but the target device has a rotation mechanism that can change the angle of the target frame, so depending on the technique to practice It can be confirmed whether the shuttle has entered the target frame (in front of it) accurately. Further, by providing a size adjustment mechanism that can adjust the size of the front surface of the target frame, that is, the target area to be narrow or wide, it is possible to prepare a target corresponding to the player's level and progress. Furthermore, since a height adjusting mechanism can be added, a position close to the upper end of the net can be targeted, and a practice position for driving can be targeted.

<First Embodiment>
The target device of the present invention is shown in FIGS. The target device 10 includes a cylindrical target frame 3 having a circular front surface (opening) 18, a table (support table) 1 that is installed on the court floor and supports the target frame 3, and the target frame 3 is mounted on the table 1. It mainly has a neck portion (rotating mechanism) 2 that is supported so as to be able to rotate (swing), a sensor 11 attached to the target frame 3, and a light emitter 4. The target frame 3 is a target for the athlete to drive the shuttle through the front face 18 into the target frame 3. A light emitter 4 is attached to the outer periphery of the upper portion of the target frame 3. As described later, the light emitter 4 emits light when a shuttle enters the target frame 3, thereby functioning as a notification body that notifies the player that the player has hit. Or you may make it always light and change a light emission pattern and a light emission color when a shuttle hits. As the light emitter 4, a plurality of LEDs may be mounted in a ring shape along the outer peripheral edge of the target frame. Alternatively, an optical fiber or a tube-shaped organic EL element may be wound. The size (diameter) of the target frame 3 can be adjusted by an adjusting mechanism described later.

  As shown in FIGS. 3 and 4, a sensor 11 that emits sensor light 12 is attached to the inner side (inner circumference) of the target frame 3. As the sensor 11, for example, an optical sensor can be used. In this example, as shown in FIG. 3 and FIG. 4 as the sensor 11, the light emitter 7 such as a light emitting diode and the light receiver 8 are 180 ° positional relation (opposite relation) with respect to the inner peripheral wall of the target frame 3 in the circumferential direction. It is attached to become. As shown in FIG. 4, it is preferable to provide two sets of light emitters 7 and light receivers 8 in the horizontal direction and the vertical direction in order to reliably detect the shuttle that has entered the target frame. By doing so, the shuttle that has entered the frame through the front surface can be reliably detected by the sensor light 12. A circuit for causing the light emitter 4 to emit light in response to a change in the detection signal from the light receiver 8 of the sensor (mechanism for operating the notification body) is electrically connected to the sensor 11 and the light emitter 4. Yes. Note that a commercially available circuit such as a switch circuit or a microprocessor can be used as a circuit for causing the light emitter 4 to emit light in response to a change in the detection signal, but is not shown here. A power source (not shown) for operating the sensor 11 is also mounted on the target device 10.

  A cross-shaped plate 6 is attached to the rear of the target frame 3 as shown in FIGS. The cross-shaped plate 6 has a cross shape in which two arms are orthogonal to each other, and four tips are attached to the rear outer periphery of the target frame 3 at an angular interval of 90 °. As shown in FIG. 11, an extension plate 6b is slidably (nested) inserted into both ends 6a of each arm of the cross-shaped plate 6, and the extension plate 6b is inserted into the tip 6a of the arm. By pulling it out, the arm of the cross-shaped plate 6 can be extended to change the length.

  The stand 1 is a quadrangular pyramid shape having a flat bottom surface so as to be installed on the court floor, and has an appropriate weight and size to support the target frame 3. As shown in FIGS. 2 and 5A, a rotating shaft 9 for attaching the neck portion 2 to the upper portion of the base 1 so as to be rotatable, that is, to be able to swing, is attached so as to protrude from the side surface. Note that FIG. 5A is a view of the platform 1 as viewed obliquely from the front, but the target frame 3 is omitted for easy understanding. As shown in FIG. 5B, the neck 2 is a U-shaped plate material having a rectangular plate 2a and two legs 2b formed by bending both ends. A shaft hole 1a that functions as a bearing is opened. By the rotation shaft 9, the neck 2 is rotated and displaced around the rotation shaft 9 in the range between the front surface 2 a 1 of the rectangular plate 2 a at the upper part of the table 1 (forward and parallel to the floor surface) and above (perpendicular to the floor surface). Swing) is possible. Further, a lock mechanism (not shown) is provided to fix the neck 2 at a desired rotational position. For example, the locking mechanism is configured by providing a protrusion or notch at the tip of the rotating shaft 9 and attaching a notch or protrusion that fits into the shaft hole 1a of the neck 2 or a ratchet mechanism. Can do. The front surface 2 a 1 of the rectangular plate 2 a of the neck portion 2 is joined to the back side of the cross-shaped plate 6.

  FIG. 6 shows a mechanism for changing the size of the target frame 3. It is a simple mechanism in which the athlete decides a size suitable for him and fastens it with a detachable fastener 14 like a clip. As the fasteners 14, velcro tapes can be attached to the two inner sides of the target frame 3 and the two outer sides of the target frame 3 at regular intervals, and the inner and outer surfaces of the target frame 3 can be fastened. When changing the size of the target, as described above, one of the two overlapping plates 6 is pulled out to change the length. By doing so, the target frame 3 can be supported on the table 1 via the neck 2 even if the size of the target frame 3 is changed. Further, since the position of the light receiver / light emitter also changes when the size of the target frame 3 is changed, the light receiver 8 and the light emitter 7 are preferably attached to the target frame 3 by a removable member such as Velcro tape.

  Next, the usage and operation of the target device 10 will be described. Place the device at the target position on the coat. In the case of badminton, as shown in FIG. For example, in the case of long serve, high clear, and hairpin, the shuttle falls at approximately 90 degrees with respect to the floor surface, so that the front surface (or opening) of the target frame that is the receiving surface is parallel to the floor surface, that is, horizontal. (See the figure on the right side of FIG. 7) In the case of smash, the shuttle is grounded at an incident angle of 20 degrees to 45 degrees with respect to the floor surface, so that the angle is 45 degrees to 70 degrees so as to be orthogonal to it. Next, the angle of the neck 2 together with the target frame 3 is changed (see the left side of FIG. 7). When the shuttle enters inside through the front surface 18 of the target frame 3, the light emitter 7 and the light receiver 8 attached to the target frame 3 detect the shuttle, and the detection signal is sent to the circuit to light the light emitter 4. As practice continues, the size of the target frame 3 and the cross-shaped plate 6 can be reduced, and the positions of the light emitter 7 and the light receiver 8 can be changed by attaching / detaching them with Velcro tape or the like. .

Second Embodiment
In the above example, the height of the target device 10 cannot be changed, and it is difficult to deal with a shuttle near the net. Therefore, the target device 10 of the second embodiment shown in FIG. 8 includes a height adjusting mechanism 16 on the base 1. The height adjusting mechanism 16 is a telescopic column that connects the base 1 and the neck 2, and the neck 2 is attached to the uppermost column. The height position of the target frame 3 can be adjusted by adjusting the length of the telescopic column according to the player's request. Since the target device 10 is the same as the target device 10 of the first embodiment except for the height adjusting mechanism 16, the description thereof is omitted.

<Third Embodiment>
In the target device 10 according to the first and second embodiments, the target frame 3 has a cylindrical shape, and the sensor light 12 has been described as a set of two light receivers and light emitters attached to the inner periphery. Various shapes such as circles, cylinders, etc. can be made. Further, as shown in FIG. 9, a plate composed of a plurality of rectangular plates is attached to the front surface of the target frame 3. At this time, the light receiver and light emitter are not attached to the plate, but a capacitive touch sensor is incorporated in the plate itself. In this case, the light emitter can be made to emit light when the shuttle hits (enters) the touch sensor (the front surface of the target frame). In this case, there is an advantage that it is possible to know in detail where the touch sensor of the target frame 3 hits. The size of the rectangular plate can be easily increased by a combination type, and the shape such as a cross, rectangle, perforated square can be changed. Thereby, it becomes possible to narrow down the range of the target to which part of the target you want to hit. As shown in FIG. 9, the light emitter 4 is attached only to the square outside the target frame.

<Deformation>
In addition to those specifically shown in the first to third embodiments, the following improvements can be added to the target device. (1) In the above embodiment, the rotation mechanism of the neck 2 can manually fix the target frame at a desired rotation position. For example, a motor and a power source are incorporated in the table 1 to electrically drive the rotation shaft 9. The neck 2 and the target frame 3 may be rotated by making them rotatable. In this case, a wireless communication facility may be attached to the target device 10 so that the motor and the power supply can be driven wirelessly from a personal computer or a smartphone. By doing this, the practitioner can change the angle of the target frame while staying on the opposite side of the court.

  (2) It is also possible to transmit the detection result wirelessly to a personal computer or smartphone through a wireless communication facility attached to the target device 10 and record the number of times of collision or passage through the personal computer or smartphone software.

  (3) A net may be attached behind the target frame. By doing so, you can quickly collect the shuttles together.

  (4) A sound generation device may be attached instead of the optical sensor as a notification body of the target device 10. Instead of illuminating the light emitter when the sensor light 12 detects the shuttle, it is possible to notify by voice whether or not the shuttle has entered the target frame by generating a sound such as “in” or “goal”. . In addition, the motivation of practice increases with voice. Alternatively, such a sound generator may be attached in addition to the optical sensor of the target device 10. By doing so, it becomes even easier to see if the shuttle hits the front of the target frame. The optical sensor and the sound generator are attached to the target frame, but may be attached to a table instead.

(5) In the first and second embodiments, the target device must be manually moved to the position where the coat is to be placed. However, like the radio control, the target device 10 is wheeled by a motor built in the table 1. You may do it. At that time, a transceiver is provided on the base 1 or the target 3 so that the remote controller can be operated. By doing this, the practitioner can hold the target device and save the trouble of carrying it to the desired position on the court, and can freely change the target position in the court while being on the opposite side of the court.
You can save yourself the trouble of holding the target device and moving it to the desired position on the court.

  Since the target device of the present invention has a target frame angle adjustment mechanism, it functions as an effective target for various tracks of a badminton shuttle. Therefore, the practice of the badminton player can be made more efficient and the motivation of the practice can be improved. Therefore, the target device of the present invention can contribute to the improvement of badminton competition in Japan.
