Description

[Detailed explanation of the invention] (a) Industrial application field The invention is a type of game of strength competition, in which two people hold each other's hands and place their elbows on the floor to twist the opponent's arm. It concerns an arm-wrestling game machine that can replace the arm of a person.

(b) Conventional technology Conventionally, in this type of arm wrestling game machine, the strength of the arm movement increases quantitatively from the start from an upright position in approximately proportion to the angle at which the arm is knocked down. Because of this, the amount of load acting on the arm from the upright starting position is large, and in order to tilt the arm, a large amount of arm strength is required from the start, giving a stiff motion sensation. Therefore, the game player often runs out of energy before he or she can tilt his or her arm significantly, resulting in a low sense of satisfaction for the game player and a lack of excitement in the game.

(c) The problem that the invention aims to solve The problem that the invention aims to solve is that when arm-wrestling, the arm of the game machine can easily knock down part way, and if you try to defeat it further and win, the counter-power of the arm of the game machine becomes weaker. By increasing the number of games, players can feel as if they are arm-wrestling against a human opponent, eliminating all of the above-mentioned drawbacks of the conventional technology, and allowing any number of players to defeat the game console's arm to a certain degree, without losing. The aim is to create an arm-wrestling game machine that is rich in flavor and provides the satisfaction of being able to defeat a large number of players.

(d) Means for Solving the Problems The present invention has been made by focusing on such conventional problems. an arm having a fixed fulcrum, a wire path in which the winding diameter of the wire is gradually increased from a substantially erect position of the arm in a direction opposite to the direction in which the arm is tilted, a wire that is wound up by the tilting of the arm; The present invention aims to provide an arm wrestling game machine consisting of a spring that pulls a wire.

(e) Effects and Embodiments Hereinafter, the structure of one embodiment of the present invention will be explained together with its effects with reference to the drawings.

A power point change plate 1 whose rotating surface is a vertical plane is rotatably mounted on a machine body (not shown) by a rotating shaft 2 provided at its center. One end of an arm 3 is fixed coaxially with the rotating shaft 2 to serve as a fixed fulcrum 4. When the arm 3 is in a substantially erect position, the force point changing plate 1 has a wire tip fixed point 5a at a predetermined position parallel to the arm 3 from the rotating shaft 2, and from there a wire is attached along the direction opposite to the direction in which the arm 3 is tilted. Then, a force point changing boss 5b is placed at a position where the radius gradually increases from the rotational diameter of the fixed point 5a.
5c, 5d, and 5e are provided as a wire path A. The tip of a wire 6 is fixed to the fixed point 5a, the rear end of the wire 6 is attached to one end of a spring 7, and the other end of the spring 7 is fixed to the fuselage. When the wire 6 is in the upright position, the spring 7 is not stretched and the wire 6 is stretched without slack.

Furthermore, the arm 3 is configured in the same manner as described above in the reverse direction of rotation, so that it can be used by both right-handed and left-handed people.

In the above configuration, when the arm 3 is tilted in the direction of the arrow in Fig. 1, the force point changing plate 1 also rotates, and the wire 6 first hits the force point change boss b, and the arm is further pushed down. This hits the emphasis change boss 5c. Therefore, when comparing the positions of the boss 5b and the boss 5c, the radius from the fulcrum 4 is larger than that of the boss 5b.
is longer. Below, in the same way, if you lower arm 3 deeply and hit bosses 5d and 5e sequentially, fulcrum 4
The radius from the arm increases gradually, and the moment acting on the arm increases accordingly. Therefore, as the arm 3 is folded down, the winding diameter of the wire gradually increases, requiring the player to apply a large amount of force.

In the above embodiment, the means for gradually increasing the winding diameter of the wire was explained using a power point changing boss, but the method is not limited to this, and the same method can be implemented even if the winding diameter is gradually increased by a pulley groove. It is possible.

(F) Effects of the invention As is clear from the above explanation, the diameter of the wire winding of the force point changing plate that winds up the wire pulled by the spring 7 increases as the arm tilts from the starting position of the upright state. , the torque acting on the arm increases as the arm tilts. Therefore, from the start with the arms upright, it is possible to knock down the opponent relatively easily up to a certain shallow angle of fall, but if you try to fall deeper than that, the opposing force of the arms increases, giving the gamer a feeling of play similar to that of a human opponent. Not only does it give the game a sense of fulfillment and satisfaction, even weak gamers can tilt their arms to a certain angle, and it also has great practical value, such as greatly increasing the enjoyment of the game. It is something that you have.
