Elderly people who train their muscles can train their upper body efficiently, and even when their leg strength is weak.

  Moreover, according to the lift training apparatus of this embodiment, the direct acting oil damper 8 as the resistance generating means gives the arm 5 a resistance force that increases as the swing speed of the arm 5 increases. For example, when the arm 5 is swung quickly, the load is large, and when the arm 5 is swung slowly, the load is small, and special tools and work are not required for adjusting the load. The upper body muscles can be easily trained according to the physical strength of the person performing the training or the purpose of training, and can be used even by a person who has relatively little physical strength.

  Furthermore, according to the lift training apparatus of this embodiment, the side plate member 9 has the stopper 30 for limiting the swing range of the arm 5, so that the arm 5 can move forward or backward when performing training. Therefore, the person who performs training can perform training safely.

  Furthermore, according to the lift training apparatus of this embodiment, since the handle 4 is formed in a substantially elliptical shape, when the seating height varies depending on the person performing training, either the upper part or the lower part of the handle 4 depending on the seating height. By holding either one, the upper body can be trained in a comfortable posture without adjusting the height of the seating member.

  Although the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described embodiments, and can be appropriately changed within the scope of the claims. For example, the resistance generating means May be a direct acting air damper or a viscous rotary damper. Further, the side plate member 9 may be omitted, and the stopper 30 may be directly fixed to the frames 12, 13 and the like at a safe position away from the handle 4.

  Thus, according to the lift training apparatus of the present invention, lift training can be performed in a state where a person who performs training is seated, so that an elderly person who trains upper body muscles for rehabilitation, muscle strength maintenance, etc. It can be used even when the leg strength is weak. Moreover, since the resistance force generating means gives the arm a resistance force that increases with an increase in the swing speed of the arm, no special tools or work are required for adjusting the load. The upper body muscles can be trained according to your physical strength or training purpose.
