The color lamp unit 101 serves as an electric referee (color lamp) provided on the fist. The color lamp unit 101 may be replaced with an electric referee (color lamp) in conjunction with an electric referee (color lamp) installed in the fist or in place of an electric referee (color lamp) Lights green. With such a configuration, it becomes easy for the audience who is not used to the game to know the victory or defeat of the player. The shape, size, quantity, and the like of the color lamp unit 101 are only one example. Can be changed appropriately.

The wheels (drive wheel 20, follower wheel 21) of the electric wheelchair 1 are hidden in the body 10, but a general one may be used. In-wheel motor drive wheel units for electric wheelchairs of various sizes (wheel diameter) in which the motor is incorporated in the wheel are commercially available from various manufacturers. By using such a unit, the drive wheel 20 can be easily manufactured. If the spokes of the wheels are exposed, there is a risk that the player's sword 30 will not be poked or pulled out of the spokes. If you try to force it out, you will not be physically able to play, such as bending or breaking. On the other hand, in the present embodiment, since the wheels (the driving wheel 20 and the follower wheel 21) of the electric wheelchair 1 are concealed by the body 10, .

Further, by providing a breaker between the motor and the battery, safety is ensured even when an excessive current flows from the battery.

As shown in Figs. 2 and 3, the seat back wall 10a of the body 10 is provided with a fixing fixture 19. As described later, the player fixes the player to the electric wheel chair 1 by connecting the body fixing band 190 to the fixing ornament 19. In addition, the seat back wall 10a functions to stabilize the position of the waist of the player so as not to fall too far backward.

Fig. 4 is a perspective view showing the electric goggles 30. Fig.

The electric goggles 30 mainly include a hilt 31, a guard 32, and a blade 33. [

The hilt 31 is a part held by the player. The front end portion of the hilt 31 is engaged with the guard 32 and the blade 33 is inserted into the hilt 31 through the guard 32 and fixed thereto. A joystick 315 is attached to the front end portion of the hilt 31. It is difficult for a player to manipulate the control space 15 (15R, 15L) in the vicinity of the grip portion 14. Such a player controls the electric wheelchair 1 by the control section 315.

On the rear side of the guard 32, a body code connector 321 and a control cable connector 322 are provided as shown in Fig. To the body code connector 321, a body code 41 is connected. To the control cable connector 322, a control cable for extracting the signal of the control point 315 is connected. A cushion 320 is disposed so as to hide the cords and cables.

The body cord 41 connected to the electric gum 30 is connected to the body code connector portion 161 of the electric wheelchair 1. [ Further, the electric cable 51 extending from the reel (electric cable reel 50) is connected to the electric cable connector portion 162. If necessary, a control cable 40 connected to the electric gauges 30 is connected to the control cable connector 160. When the control cable 40 is connected to the control cable connector unit 160, the operation signal from the control unit 15 is invalidated and the electric wheelchair 1 is controlled by the control unit 315 (override system) .

6 is a view for explaining a method of using the electric wheelchair 1. In addition, various electric cords and cables are omitted in order to avoid troubles in drawings.

As shown in Fig. 6, a player who controls the electric sword 30 with his or her left hand sits with the footrest 12 on the right side edge 11b, and sits on the right side edge 11b. Then, both legs are fixed by the respective fixing bands 13, and the body fixing band 190 is connected to the fixing ornamental 19. In this way, the player is fixed to the electric wheelchair 1. Then, while holding the grip portion 14 with the right hand, the control portion 15 (15R) is operated.

As described above, the seat portion 11 of the electric wheel chair 1 of the present embodiment includes the right arm 11b extending from the top 11a, which becomes the front end in the traveling direction of the electric wheel chair in plan view, And a left front lid 11c extending in a leftwardly inclined rear direction. The player can be arranged such that the arm that controls the electric gauntlet 30 approaches the opponent player simply by sitting on the right arm 11b or the left arm 11c. Conventionally, there was a competition called " wheelchair fencing ", but there was no electric wheelchair suitable for fencing and the wheelchair was fixed in an oblique direction with respect to the opponent. Even if the electric wheelchair is forced to be opposed to the opponent, it is very difficult to maneuver if the fencing is performed using an electric wheelchair and the robot is moved and spaced apart. On the other hand, the seat portion 11 of the electric wheel chair 1 of the present embodiment includes a right arm 11b extending from the top 11a in the rearward direction of the right tilting and a left tilting 11c extending in the leftward tilting back direction And the player can be provided in the oblique direction with respect to the opponent player simply by sitting on the right throw 11b or the left turn 11c. And if you move forward and backward in this state, you can easily take opportu- nity to the opponent, and it is easy to steer.

Since the grip portion 14 is provided behind the seat portion 11 so as to be positioned at the height of the waist of the player sitting on the seat portion 11, the player can grip the grip portion 14 while moving his / 15R and 15L are provided in the vicinity of the grip portion 14 so that the player can grip his or her favorite joystick 14 with the hand holding the grip portion 14 during the game 15R, and 15L, it is suitable for a right-handed player or a left-handed player. If the backrest is provided on the electric wheelchair 1 and the grip portion 14 is positioned on the backrest, The grip portion 14 of the electric wheelchair 1 of the present embodiment is disposed at a position lower than the height of the waist of the player sitting on the seat portion 11, The reporter will easily hold the balance jwigoseo the grip (14) moves the upper body during the race.

The seat portion (11) is rotatable at a predetermined angle on the pedestal portion (110). Thereby, the player can finely adjust the position of the seat portion 11 in accordance with his / her preference.

The footrest 12 attached to the seat portion 11 is freely attachable and detachable to either the right arm 11b or the left arm 11c of the seat portion 11. [ The electric wheel chair 1 of the present embodiment has a small angle at which the seat portion 11 can be pivoted but the position of the footrest 12 is changed so that the player who controls the electric sword 30 with his / 30 can be operated by the right hand, the electric wheel chair 1 of the present embodiment can be used.

Also, under the seat portion 11, leg fixing bands 13L and 13R are attached. By fixing the legs with the leg fastening bands 13L and 13R, even if the player is moving his / her upper body heavily, it becomes difficult to fall off from the electric wheelchair 1. Also, by connecting the body fixing band 190 to the fixed decoration 19, the player is fixed to the electric wheel chair 1 and is hard to roll down, thereby ensuring the safety of the player.

An emergency stop switch 17 is provided at an upper portion of the body 10. When the emergency stop switch 17 is depressed, the supply of electric power to the drive wheel 20 is stopped and the electric wheelchair 1 is stopped. Since the emergency stop switch 17 is provided on the upper portion of the body 10, it is possible to operate the switch 17 by not only a player but also a referee, thereby ensuring the safety of the player.

At the bottom of the body 10, a collision avoidance sensor 18 is provided. Since there is the collision preventing sensor 18, when the electric wheelchair of the opponent is too close to the electric wheelchair, the supply of electric power to the drive wheel 20 is stopped, thereby ensuring the safety of the player.

The electric cable 51 extending from the reel (electric cable reel 50) is conventionally connected to the body code connector 321 of the electric gum 30 as shown in Fig. When such a thing is used for the fencing of the electric wheel chair, the electric cable 51 is stretched and contracted by the force of the flat spiral spring provided inside the reel (electric cable winder 50) in accordance with the forward and backward movement of the electric wheelchair, It is an obstacle to the player. 5, the electric cable 51 extending from the reel (electric cable winder 50) is connected to the electric cable connector portion 162, and the electric cable 51 The body code 41 connected to the body code connector portion 161 is connected to the body code connector portion 161. In this way, since the relative positional relationship between the player and the body code 41 becomes constant, the player does not feel troublesome. 7, the electric cable 51 is long, and in particular, the electric cable 51 coming out from the player is wound on the reel 50 while being pulled from the top of the body 10 to the pist. If the electric cable 51 on the body 10 is easily moved (easy to break) and the speed at which the electric cable 51 is wound up, such as the reel 50 sags, (51) is easily twisted. In this state, when the electric wheel chair is retracted, the electric cable 51 may be stepped on or wound on the body 10 or the drive wheel 20. [ On the other hand, according to the present embodiment, since the electric cable 51 is not provided on the body 10, the electric cable 51 can be shortened, so that the electric cable 51 can be shortened by being stepped on by the body 10 or the drive wheel 20, Interferes with, or is wound easily.

In addition, if the electric cable 51 is provided in a double structure to supply electric power for driving from the outside, it is not necessary to mount the battery on the electric wheel chair 1, so that the electric wheel chair 1 can be lightened. Also, the battery will not run out even if the playing time is long.

Further, since the color lamp unit 101 is formed on the body 10, it is easy for a spectator who is unfamiliar with the game to know whether or not the player has won or lost.
