  Hereinafter, embodiments of the present invention will be described in detail.

  The shuttle launching device of the present invention is a single-shot shuttle launching device for launching a shuttle 100 comprising a hitting portion 100a and a conical blade portion 100b, and includes a holding means for holding the shuttle 100, and a hitting portion 100a. And launching means for launching the shuttle 100 starting from the head.

  The holding means is formed so as to hold the inside of the blade portion 100 b of the shuttle 100. Thus, the shuttle 100 can be held with the hitting portion 100a at the head until the shuttle 100 is launched. Here, the shuttle 100 is usually formed by combining 16 blades in a conical shape on a plane of a substantially hemispherical hitting portion 100a formed of cork or the like. Therefore, for example, a commercially available 16-groove gear can be used as the holding means, and the gear groove and the 16 shuttle 100 blades can be fitted and held. In this way, the holding means can be formed at low cost by using a commercially available gear that is generally distributed. The holding means is not limited to this as long as it holds the inside of the blade portion 100b of the shuttle 100. For example, the holding means may be held by a conical shape along the inner surface of the shuttle 100. .

  The launching means is a means for firing the shuttle 100 by applying a pressing force to the blade portion 100b side of the hitting portion 100a of the shuttle 100. For example, the firing means is formed so as to hit the blade portion 100b side of the hitting portion 100a of the shuttle 100 with a rod. It ’s fine. Any method may be used to move the rod. For example, there is a method in which the elastic force of a spring is applied to the rod and the elastic force is released by a firing switch or the like to move the rod. As another method, a compressor (power source) that compresses gas to increase pressure, a pressurized tank that stores the gas, a piston and a cylinder that are movable by supplying and discharging gas, and a gas in the pressurized tank There is a method of moving the rod with this piston using a pipe (compressed air supply flow path) to be sent to the cylinder and an on-off valve (launch switch) for switching supply and stop of the gas to be sent to the cylinder. In this case, the piston and the rod may be integrally formed. It should be noted that the launch switch can be formed so that the timing of launching the shuttle 100 is manually performed or can be formed automatically.

  Further, the compressed gas may be directly injected and blown to the blade portion 100b side of the hitting portion 100a of the shuttle 100 without using the rod. In this case, for example, a compressor (power source) that compresses the gas to increase the pressure, a pressurized tank that stores the gas, and the compressed gas is injected so as to hit the blade side of the striking portion 100 a of the shuttle 100. It consists of an injection nozzle (force transmission part) that performs, a pipe (compressed air supply flow path) that sends gas in the pressurized tank to the injection nozzle, and an on-off valve (fire switch) that switches between supply and stop of the gas sent to the injection nozzle Just do it. In this case as well, the launch switch can be formed so that the timing of launching the shuttle 100 is manually performed, or can be formed automatically.

  Further, the launching means may be provided with a speed adjusting means for adjusting the speed of the shuttle 100 to be fired by adjusting the pressing force applied to the hitting portion 100a of the shuttle 100. For example, if a spring is used for the power of the launching means, the amount of expansion and contraction of the spring may be adjusted. If compressed gas is used for the power of the launching means, the pressure of the gas should be adjustable. good.

  Another shuttle launching device of the present invention is a continuous-type shuttle launching device for continuously firing the shuttle 100 including the hitting portion 100a and the conical blade portion 100b. It mainly comprises holding means for holding, firing means for applying a force to the blade portion 100b side of the hitting portion 100a, and switching means for switching the relative position of each shuttle 100 with respect to the firing means.

  The holding means is formed so as to hold the plurality of shuttles 100 inside the blade part 100 b of the shuttle 100. For example, a plurality of 16-groove gears may be arranged at equal intervals on the same circle, and the gear grooves and the 16 shuttle 100 blades may be fitted and held.

  The launching unit may be any type as long as it can apply a pressing force to the blade portion 100b side of the hitting portion 100a of the shuttle 100 in order to launch the shuttle 100 held by the holding unit. Like the above, the blade 100b side of the hitting portion 100a of the shuttle 100 may be formed so as to hit with a rod. Moreover, the method of moving a rod can utilize the elastic force of a spring, or compressed gas, for example. Further, the compressed gas may be directly injected and blown to the blade portion 100b side of the hitting portion 100a of the shuttle 100 without using the rod.

  Further, the launching means may be provided with speed adjusting means for adjusting the speed of the shuttle 100 to be fired by adjusting the pressing force applied to the hitting portion 100a of the shuttle 100, as in the single shot type. For example, if a spring is used for the power of the launching means, the amount of expansion and contraction of the spring may be adjusted. If compressed gas is used for the power of the launching means, the pressure of the gas should be adjustable. good.

  The switching means is for firing a plurality of shuttles 100 held by the holding means by a single launching means by switching the relative position of the shuttle 100 with respect to the launching means. For example, a ratchet mechanism that rotates the holding means by a predetermined angle in a certain direction in conjunction with the movement of the firing means may be used.

  Further, in both the single-shot type and the continuous-shot type, it is possible to form a firing direction adjusting means for adjusting the direction of the shuttle 100 to be fired (the vertical and horizontal angles of the shuttle 100 to be fired). Thereby, since the launch direction of the shuttle 100 can be easily adjusted, it is possible to effectively practice badminton.

  Hereinafter, the continuous-shot shuttle launcher of the present invention will be described by way of examples, but the present invention is not limited to this.

  As shown in FIG. 1, the shuttle launcher is fixed on a base 1 for installation on the ground or the like via launch direction adjusting means (turntable 2 and base shaft 5), and holds a plurality of shuttles 100. The relative position of each shuttle 100 with respect to the launching means (the launching spring 29, the rod 54, etc.) and the launching means (the launching spring 29, the rod 54, etc.) for applying force to the blade part 100b side of the hitting part 100a Switching means (ratchet wheel 15 and ratchet pawl 25, etc.).

  The holding means is mainly configured by a disc-shaped main disk 11 that can rotate around the main shaft 7 and 16-groove gears 52 that are arranged at six positions on the main disk 11 at intervals of 60 degrees. As shown in FIG. 2, the gear 52 has a nozzle 51 fixed to the main disk 11 connected to a central hole. A rod 54 in which an elastic force of a spring (not shown) is urged in the direction of the main disk 11 is fitted in a through hole provided in the nozzle 51.

  As shown in FIGS. 1 and 3, the launching means includes a launching spring 29 serving as a power source for launching the shuttle 100, the above-described rod 54, and an elastic force biased by the launching spring 29. 54, a launch pin 67 and a launch block 61 for launching the shuttle 100, a handle 78 for energizing the launch spring 29, and a lever for releasing the energized elastic force. 37 (launch switch).

  The launch block 61 is fitted with a main shaft 7, a guide pin 28 and a sub shaft 22 provided in parallel to the main shaft 7, and is slidable with respect to the main shaft 7 and the sub shaft 22. Formed. Further, the ejection pin 67 is fixed to the ejection block 61. At this time, the ejection pin 67 is fixed at a position aligned with the rod 54.

  The launching spring 29 is inserted into the guide pin 28 and expands and contracts by sliding of the launching block 61, and the elastic force is urged or released. The guide pin 28 is formed with a fixing means 30 (speed adjusting means) for sandwiching the launching spring 29 together with the launching block 61. By changing the position of the fixing means 30 on the guide pin 28, the elastic force biased by the launching spring 29 can be adjusted, and the firing speed of the shuttle 100 can be adjusted.

  The lever 37 (firing switch) is formed in a substantially V-shape including a main lever 37a extending in a substantially vertical direction with respect to the base 1 and a sub lever 37b extending in a substantially horizontal direction with respect to the base 1. 5 is formed so as to be rotatable around the center. The main lever 37 a is connected to the launch block 61 via the rod 33.

  The handle 78 is formed with a lever block 71 that rotates as the handle 78 rotates. Then, by manually rotating the handle 78, the lever block 71 rotates and contacts the bearing 38 provided on the main lever 37a. When the handle 78 is further rotated, the bearing 38 is pushed by the lever block 71, and the lever 37 (main lever 37a) can be pulled through the bearing 38. At this time, since the driving block 61 is connected to the rod 33, the main shaft 7 and the sub shaft 22 slide in the direction of the main lever 37a against the elastic force of the driving spring 29. In other words, by rotating the handle 78, the launching spring 29 is contracted and the elastic force is urged. When the handle 78 is further rotated, the bearing 38 of the main lever 37a is detached from the lever block 71 by the rotation of the lever block 71 and the rotation of the main lever 37a. Then, the elastic force urged by the launch spring 29 is released, and the launch block 61 and the launch pin 67 are pushed out to the holding means side. As a result, the launch pin 67 strikes the rod 54 and the shuttle 100 is launched. When the handle 78 further rotates, the lever block 71 again comes into contact with the bearing 38 and pulls the lever 37 (main lever 37a).

  Note that when the bearing 38 of the main lever 37a is disengaged from the lever block 71, the shock is prevented between the lever block 71 and the handle 78 in order to prevent the handle 78 from rotating rapidly. You may provide the buffer means which buffers. For example, as shown in FIG. 3, a buffer disk 77 (see FIG. 4) having a groove 77a formed by cutting a part of a cylinder into a semicircular shape is formed on the handle 78 side, and on the lever block 71 side. Then, a collar 76 (see FIG. 5) having a pin 76a projecting so as to come into contact with the groove 77a of the buffer disk 77 in a part of the cylinder is formed. Thus, when the handle is rotated against the elastic force of the launch spring 29, the pin 76a comes into contact with the groove 77a of the buffer disk 77. Further, when the bearing 38 of the main lever 37 a is disengaged from the lever block 71, the lever block 71 and the collar 76 rotate, but the pin 76 a of the collar 76 rotates freely between the grooves 77 a of the buffer disk 77. The rotating force is not transmitted to the buffer disk 77 side, and the shock can be buffered.

  As shown in FIG. 6, the switching means is mainly composed of a ratchet wheel 15 (gear) and a ratchet pawl 25 that constitute a ratchet mechanism.

  The main disk 11 is fixed to the ratchet wheel 15, and the main disk 11 also rotates as the ratchet wheel 15 rotates. In addition, the ratchet wheel 15 is formed with a plurality of slanted grooves into which the ratchet claws 25 can be fitted.

  The ratchet pawl 25 is connected to one end side of a ratchet lever 18 that can rotate around the main shaft 7, and an elastic force is applied to the ratchet wheel 15 side by a leaf spring 27 fixed to the ratchet lever 18. It is energized. The other end side of the ratchet lever 18 is connected to the sub lever 37b via the rod 33 so that the ratchet lever 18 rotates 60 degrees around the main shaft 7 by the vertical movement of the sub lever 37b. It is formed.

  Next, the operation of the switching means will be described. When the handle 78 is turned, the lever 37 is pulled through the lever block 71 and the bearing 38 as described above. Then, the ratchet lever 18 rotates 60 degrees around the main shaft 7 in conjunction with the tip of the sub lever 37b and the rod 33 being pushed upward. Next, the ratchet claw 25 fitted in the groove of the ratchet wheel 15 also rotates the ratchet wheel 15 by 60 degrees, and accordingly, the main disk 11 fixed to the ratchet wheel 15 also rotates by 60 degrees. Thereby, the shuttle 100 currently hold | maintained at a 60 degree space | interval in a holding means is each switched. When the bearing 38 is disengaged from the lever block 71, the tip of the sub lever 37b is lowered downward, and the ratchet lever 18 rotates 60 degrees in the reverse direction around the main shaft 7 to return to the original position. Because of this, the ratchet pawl 25 is easily removed from the groove of the ratchet wheel 15, so that the ratchet wheel 15 and the holding means do not rotate.

  Thereby, after one of the shuttles 100 is launched by the launching unit, the switching unit switches the position of the other shuttle 100 held by the holding unit in conjunction with the movement of the launching unit to prepare for the next launch. it can.

  The firing direction adjusting means is mainly composed of a turntable 2 that adjusts the horizontal position of the holding means relative to the base 1 and a base shaft 5 that adjusts the vertical angle of the holding means relative to the base 1.

  The turntable 2 is formed to be rotatable in the horizontal direction with respect to the base 1 by ball bearings. A base shaft 5 is fixed on the turntable 2.

  The base shaft 5 rotatably supports the holder 6 to which the main shaft 7 and the sub shaft 22 are fixed.

  Thereby, the holding means supported by the main shaft 7 and the sub shaft 22 can be rotated in the horizontal direction by the turntable 2 (see FIG. 7), and the vertical angle is adjusted by the base shaft 5. (See FIG. 8).

  By configuring the shuttle launching device in this way, it is possible to easily and inexpensively form a device that can launch the badminton shuttle 100 at a relatively high speed.

  In the above description, the holding means has a configuration in which a plurality of 16-groove gears 52 are arranged on the rotatable disc-shaped main disk 11. However, the holding means is not limited to this, and is described in, for example, FIG. As described above, the main disk 11A having a ratchet mechanism and capable of rotating in a fixed direction around the main shaft 7 and the sub disk fixed to the main disk 11A so as to be rotatable at a constant interval on the same plane. 11B, a chain 11C that can move by engaging a part of the circumference of the main disk 11A and the sub disk 11B, and a 16-groove gear 52 that is fixed on the chain 11C at equal intervals and holds the shuttle 100. It is also possible to do. In this way, more shuttles can be held.
