Description

  The present invention relates to a kendo basic training machine that allows one person to perform face-to-face and hand-to-hand practice in practicing kendo.

  In general, in kendo practice, the most important basic strike is the practice of face-to-face and small-hand strike. Is doing.

  However, in such practice methods, there is a problem that an instructor or a person who always holds a bamboo sword is required, and that it is impossible to practice as much as you want when you like it alone.

  Therefore, Japanese Laid-Open Patent Application No. 10-155962 provides a kendo practice tool that allows one person to practice face and hand strikes. This is a means for returning the beating arm or hand-handed arm that has been rotated horizontally to the retracted position so that the practitioner can pass through when hitting the beating arm or hand-handing arm. It consists of a shock absorber with a built-in hydraulic damper and spring and a weight, and an electric motor with a brake pad that adjusts the tightening force by springs, spring pins and nuts, and adjusts the rotation speed and stop position. .

In such a conventional structure, hydraulic dampers and springs with a complicated structure and an expensive spring that constitute a large number of plate-like bodies that open and close the apertures that generate oil resistance and erase oil resistance The cost is increased by the electric motor equipped with the brake pad that adjusts the tightening force with the spring pin and nut, and adjusts the rotation speed and stop position. Depending on the level of the striking force depending on the person, the reaction force of the hydraulic damper and mainspring and the action of the brake pads of the motor do not allow the face arm or hand arm to be quickly turned to the avoidance position. There is a problem that a practitioner when hitting an arm has a problem that affects the timing of passing through.
Japanese Patent Laid-Open No. 10-155962

  The object of the present invention is to quickly turn the face hitting arm or hand hitting arm to the avoidance position regardless of the strength of the hitting force when hitting the face hitting arm or hand hitting arm. It is to provide a low-cost kendo basic training machine that does not affect the structure and is simple in structure.

  In order to achieve the above object, the present invention provides a striking position as claimed in claim 1, wherein a striking arm is extended in a horizontal direction on a strut that is erected on a base and is adjustable in the vertical direction. And a hand hitting body that is pivotable at the retracted position and a hand hitting main body that is pivoted between the hitting position and the retracted position by extending the hand hitting arm in the horizontal direction. A spring for rotating the face-making arm and the hand-handing arm to the retracted position and a rope for winding the surface-arm and the hand-handing arm are wound on the face-making body and the hand-handing body. The brake motor for rotating from the retracted position to the hitting position, and when the arm for face hitting arm and the arm for small hand hitting are turned to the hitting position, the brake motor is stopped and braked, and from the hitting position. In the retracted position It has a limit switch and a control device for rotating the brake motor after a few seconds when it is moved, winding the rope and turning it to the hitting position. A sound detector is provided for detecting a hitting sound to release the brake of the brake motor and to rotate the surface hitting arm and the hand hitting arm to a retracted position.

  According to the present invention, regardless of the practicing force of the practitioner, the beating arm or the hand-pushing arm can be quickly rotated to the avoidance position so that the practitioner can pass through. This has the effect of enabling the hand arm to be turned to the retracted position and returned to the hit position.

  The best mode for carrying out the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a base. A wheel 2 with a stopper is provided on the lower surface of the base 1 and is portable. On the base 1, a pair of support columns 3 a and 3 b are erected with a front-rear phase difference. That is, one support column 3a is erected so as to be located behind the other support column 3b. The struts 3a and 3b are adjustable in the vertical direction, and are set at the expansion / contraction adjustment position with a thumbscrew.

  A face-making main body 4a is supported on the one strut 3a, and a small-hand hitting main body 4b is supported on the other strut 3b. The beating main body 4a is provided with a beating arm 5 extending in the horizontal direction so as to be rotatable at an angle of 90 degrees between the beating position and the retracted position. The small beating main body 4b is also small. A hand strike arm 6 extends in the horizontal direction and is provided to be rotatable at an angle of 90 degrees between the strike position and the retracted position.

  The face hitting main body 4a is provided with a mechanism for rotating the face hitting arm 5 at an angle of 90 degrees between the hitting position and the retracted position, and the hand hitting main body 4b hits the hand hitting arm 6. A mechanism that rotates at an angle of 90 degrees between the position and the retracted position is provided. Since this mechanism has the same structure for both the face-making body 4a and the hand-handling body 4b, it will be described as a representative of the face-making body 4a with reference to FIGS.

  The face-arm 5 (small arm 6) is fixed to the upper end of the shaft 7 in the vertical axis direction rotatably supported by the upper and lower pillow blocks 8a, 8b. The shaft 7 extends in a direction perpendicular to the axes of the rope arm 9 and the face-arm 5 (small hand arm 6) extending coaxially with the face-arm 5 (small hand-arm 6). An existing spring arm 10 is attached.

  One end of a rope 14 stretched over a pulley 13 of the brake motor 12 is coupled to the rope arm 9, and one end of the rope arm 10 is attached to the face-making main body 4 a (small hand-working main body 4 b). The other end of the spring 11 is coupled, and the surface strike arm 5 (small hand strike arm 6) is rotated to the avoidance position indicated by the dotted line in the drawing by the tensile force of the spring 11.

  Further, the limit switch 18 and the face hitting arm 5 (small hand hitting arm 6) are detected when the face hitting arm 5 (small hand hitting arm 6) is rotated to the avoidance position indicated by the dotted line in the figure. A sound detector 15 is provided for detecting vibration sound when struck.

  Further, a control device 16 for controlling the rotation and stop of the brake motor 12 and the operation and release of the brake according to signals from the limit switch 18 and the sound detector 15 is also provided. In FIG. 3, reference numeral 17 a indicates a hitting position stopper of the face hitting arm 5, and reference numeral 17 b indicates an avoidance position stopper of the hand hitting arm 6.

  Since the present invention has the structure as described above, at the striking position of the beating arm 5 and the small arm 6, the rope 14 is wound around the pulley 13 by the brake motor 12 and the shaft 7 is moved via the rope arm 9. The arm 5 for rotating and the arm 6 for small hitting are brought into contact with the hitting position stopper 17a. The limit switch 18 stops the rotation of the brake motor 12 while the beating arm 5 and the small hitting arm 6 are in contact with the hitting position stopper 17a. The arm 6 is fixed at the hitting position. At this time, the spring 11 connected to the spring arm 10 extends as shown by a solid line in FIG. 4 to generate a tensile force that rotates the face-pick-up arm 5 and the hand-pick-up arm 6 toward the retracted position. However, the brake of the brake motor 12 is prevented from rotating in the direction of the retracted position and is held at the tapping position.

  In a state where the beating arm 5 and the hand strike arm 6 are held at the beating position, the practitioner hits the hand beating arm 6 located below with a bamboo sword, and then moves the face beating arm 5 located above. Beat it. At this time, in order for the practitioner to move forward by passing forward and pass through, the arm 6 for small hitting and the arm 5 for hitting the face rotate 90 degrees from the hitting position to the retracted position.

  The operation is carried out by detecting a vibration sound when the hand strike arm 6 and the face strike arm 5 at the hitting position are hit with a bamboo sword by the sound detector 15, and the control device 16 uses the signal to brake the brake motor 12. Open. As a result, due to the tensile force of the spring 11, the hand-handing arm 6 and the face-arming arm 5 are rotated 90 degrees from the hitting position to the retracted position via the spring arm 10 and the shaft 7, and abut against the avoidance position stopper 17b. At this time, the rope 14 wound up by the pulley 13 is rewound.

  The limit arm 18 is activated when the small arm 6 and the surface arm 5 are rotated 90 degrees from the striking position to the retracted position, and the brake motor 12 is rotated several seconds later by a timer built in the control device 16. Then, the rope 14 is wound up by the pulley 13 and the shaft 7 is rotated via the rope arm 9 so that the beating arm 5 and the small arm 6 are brought into contact with the tapping position stopper 17a. The limit switch 18 stops the rotation of the brake motor 12 while the beating arm 5 and the small hitting arm 6 are in contact with the hitting position stopper 17a. The arm 6 is fixed at the tapping position, and the next tapping practice is ready.

  In this way, in the present invention, the vibration sound when the hand arm 6 and the face arm 5 are struck with a bamboo sword is detected by the sound detector 15, and the brake of the brake motor 12 is controlled by the control device 16 by the signal. Opening and rotating the hand-picking arm 6 and the face-pick-up arm 5 by 90 degrees from the tapping position to the retracted position by the tensile force of the spring 11, so that it is quick and reliable immediately after tapping regardless of the practicing tapping force. Then, it is rotated 90 degrees to the retracted position, and the trainee moves forward to ensure passage.

  In addition, since the struts 3a and 3b can be adjusted up and down in the vertical direction, it is possible to adjust the appropriate hitting position according to the extension of adults and children. It has the advantage of being able to provide a Kendo basic training machine at a low cost with a simple structure.
