Arm wrestling aids

Abstract

This invention provides an assistive device that prevents the hand from slipping or intentionally letting go during arm wrestling, and allows each competitor to choose to use either their left or right hand. [Solution] A frame 6 consisting of an upper wall 2, a lower wall 3, and a pair of left and right side walls 4 and 5, with two opposing sides open, has a pair of thumb insertion holes 9 and 10 provided in the upper wall 2. Each competitor inserts their hand from the opposite open sides 7 and 8, protruding their thumb through the corresponding thumb insertion hole 9 and 10, and protruding the other four fingers to the opposite side to grasp the separate side walls 4 and 5. This allows for a competition of arm strength using the same assistive device 1 without directly joining hands.

Description

Technical Field

[0001] The present invention relates to an auxiliary tool used when performing arm wrestling, and particularly relates to an arm wrestling auxiliary tool for two competitors to compete in arm strength by gripping the same frame-shaped tool respectively without directly interlocking their hands with each other.

Background Art

[0002] In general arm wrestling, two competitors interlock their respective hands and apply force with their palms and fingers in mutual contact.

[0003] However, if the hand slips due to sweating or other reasons during the competition, the interlocked hands may come apart and the competition may be interrupted. In addition, it is difficult to objectively judge whether one competitor intentionally released their hand to avoid a disadvantageous state, which may impair the fairness of the competition.

[0004] Furthermore, in the conventional method of directly interlocking hands, both sides usually need to use the hand on the same side, making it difficult to conduct the competition with a combination where one uses the right hand and the other uses the left hand.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The present invention has been made in view of the above circumstances, and aims to provide an auxiliary tool for arm wrestling that suppresses accidental slipping-off and intentional release of hands during arm wrestling, facilitates continuation of the competition, and allows competitors to individually select whether to use the left or right hand.

[0006] In addition, the present invention aims to provide an auxiliary tool for arm wrestling that has a simple structure and is easy to manufacture and use.

Means for Solving the Problems

[0007] To solve the above problems, the arm wrestling aid according to the present invention comprises a frame having an upper wall, a lower wall, and a pair of left and right side walls, with two opposing surfaces open, and a pair of thumb insertion holes formed in the upper wall at intervals in the left-right direction.

[0008] Each competitor inserts their hand into the frame from opposite open sides, extending their thumb upward through the corresponding thumb hole and their other four fingers toward the opposite open side, grasping one of the pair of side walls with their thumb and four fingers. This allows the two competitors to apply force to each other through the frame while each grasping different side walls of the same frame.

[0009] The pair of thumb insertion holes can be positioned close to their corresponding side walls. Furthermore, the outer corners and opening edges of the frame can be rounded to prevent localized pressure from concentrating on the hand. [Effects of the Invention]

[0010] According to this invention, since each competitor's hand is held by the corresponding side wall of the frame, it is possible to suppress the accidental slippage of the hand during the competition. In addition, it becomes easier to check if a competitor's hand has left the support device, thereby deterring intentional detachment and improving the fairness of the competition.

[0011] Furthermore, since there is no need for competitors to directly touch hands, each competitor can individually choose either their right or left hand, and the competition can be played not only when both players use the same hand, but also when one player uses their right hand and the other uses their left hand.

[0012] Furthermore, because it has a simple frame-like structure mainly consisting of an upper wall, a lower wall, and a pair of left and right side walls, it is easy to manufacture and use. [Brief explanation of the drawing]

[0013] [Figure 1] This is a perspective view showing the structure of the arm wrestling aid according to the present invention. [Figure 2] This is a perspective view showing a first usage state in which two competitors are gripping the arm wrestling aid according to the present invention. [Figure 3] This is a perspective view showing a second usage state in which two competitors are gripping the arm wrestling aid according to the present invention. [Figure 4] This is a front view showing the use of the arm wrestling aid, with one competitor using their left hand and the other using their right hand. [Modes for carrying out the invention]

[0014] The embodiments of the present invention will now be described with reference to the drawings. As shown in Figure 1, the arm wrestling aid 1 is formed into a roughly rectangular frame 6 by an upper wall 2, a lower wall 3, and a pair of left and right side walls 4, 5. The front and rear surfaces of the frame 6 are open, forming open surfaces 7, 8 through which the competitor's hands and fingers can be inserted.

[0015] Two thumb holes 9 and 10 are formed in the upper wall portion 2, spaced apart in the left-right direction. Each thumb hole 9 and 10 is sized to allow the athlete's thumb or the base of their thumb to pass through comfortably, and is positioned near the corresponding side wall portions 4 and 5. In the illustrated example, the thumb holes 9 and 10 are approximately circular or elliptical in shape, but are not limited to these shapes as long as they allow the thumb to pass through.

[0016] The outer corners, inner corners, and opening edges of the frame 6 are preferably formed in a rounded shape. This reduces localized pressure on the hand when gripping and also reduces the strain on the hand when it comes into contact with the edges of the frame 6 during play.

[0017] When in use, the first competitor inserts their hand into the frame 6 through one open surface 7 and extends the thumb corresponding to the hand being used upward through one thumb insertion hole 9. Furthermore, the other four fingers extend toward the other open surface 8, and the thumb and the four fingers grip one side wall portion 4 between them.

[0018] The second athlete inserts their hand into the frame body 6 from the open surface on the side opposite to the first athlete, and similarly, makes the thumb protrude upward from the other thumb insertion hole 10, and makes the four fingers other than the thumb protrude to the opposite side to grip the other side wall portion 5. Thereby, both athletes' hands can be held by the same assisting tool without directly bringing the palms and fingers of the two athletes into contact with each other.

[0019] Figure 2 and Figure 3 show usage examples where two athletes each use the hand on the same side. Regardless of whether both use the right hands R1, R2 or both use the left hands L1, L2, each athlete can grip the different side wall portions 4, 5 to compete in arm strength.

[0020] Figure 4 shows a usage example where one athlete uses the left hand L1 and the other athlete uses the right hand R2. In the present invention, since both hands are not brought into direct contact, the competition can be carried out even with such a combination using hands on different sides.

[0021] During the competition, with each athlete sufficiently gripping the corresponding side wall portions 4, 5 of the assisting tool 1, a force is applied in the direction of tilting the assisting tool 1 toward oneself or rotating the assisting tool 1. The event that the assisting tool 1 has moved to a predetermined position or a predetermined angle, or the event that one athlete's hand has separated from the assisting tool 1, or the like, can be used as a pre-determined win / loss criterion.

[0022] The frame body 6 is formed of a material having rigidity capable of withstanding the force acting during the competition. For example, synthetic resin, metal, wood, fiber-reinforced material, or a combination thereof can be used. Further, the frame body 6 may be integrally molded, or may be formed by joining a plurality of members. The vertical and horizontal dimensions, depth dimension, wall thickness, and dimensions of the thumb insertion holes of the frame body 6 can be appropriately set according to the size of the user's hand and the assumed competitive force. The shape of the side wall portions 4, 5 is partially widened with a curved line in the front-rear dimension to improve the fit when gripped by fingers.

[0023] The embodiments of the present utility model have been described above, but the present utility model is not limited to the above embodiments, and various modifications can be made within the scope of the configuration described in the claims of the utility model registration.

Industrial Applicability

[0024] The arm wrestling aid according to the present utility model can be manufactured and used as toys, amusement appliances, competition appliances, exercise training appliances, and the like.
