Embodiments of the present application provide a flywheel-type seated calf trainer, which is used for a user to perform calf raising training in a sitting posture, so as to train the user's calf muscles.

Please refer to the accompanying drawings 1-2, the flywheel type sitting posture calf training device provided by the embodiment of the present application includes a frame 10, a pedal part 20, a seat part 30, a leg pressing part 40, a drawstring 50, a counterweight flywheel 60 and Regulator 70. The frame 10 includes a frame body 11 and a rotating member 12 , and the rotating member 12 is rotatably disposed on the frame body 11 . Along the rotation direction, the rotating member 12 has a plurality of rotation positions arranged at intervals along the rotation direction, and the plurality of rotation positions include an initial position. The pressing leg portion 40 is disposed on the rotating member 12 , and the pressing leg portion 40 moves along with the rotating member 12 . Both the seat portion 30 and the footrest portion 20 are disposed on the frame body 11 , the footrest portion 20 and the leg pressing portion 40 are located on the same side of the seat portion 30 , and the footrest portion 20 is located below the leg pressing portion 40 . The counterweight flywheel 60 includes a wheel body portion 61 and a flywheel shaft 62 , the wheel body portion 61 is mounted on the flywheel shaft 62 , and the counterweight flywheel 60 is rotatably arranged on the frame body 11 through the flywheel shaft 62 . The first end of the pull cord 50 is connected to the flywheel shaft 62 so that the pull cord 50 can be wound or released by the rotating flywheel shaft 62 . The adjusting device 70 is connected to the second end of the pull cord 50 , wherein the adjusting device 70 is movably disposed on the rotating member 12 to adjust the maximum retractable amount of the pull cord 50 on the flywheel shaft 62 .

The process of the user using the flywheel-type sitting posture calf training device for calf raising training is as follows: the user sits on the seat 30, the feet are placed on the pedals 20, the thighs are located under the leg press 40 and are connected to the leg press 40. Contact, and then perform heel raising training. Heel raising training includes heel raising training and heel returning training in sequence. Slowly fall back.

The rotation direction of the rotating member 12 includes the opposite first rotating direction and the second rotating direction, the rotating member 12 rotates along the first rotating direction during the heel-raising action, and the rotating member 12 rotates along the second rotating direction during the heel-returning action . It can be understood that the initial position of the rotating member 12 refers to the initial position of the rotating member 12 along the first rotating direction. The stay cord 50 includes a first end, a second end and a main cord segment between the first end and the second end, the stay cord 50 is connected through the first end to the flywheel shaft 62 and through the second end to the adjustment device 70 . It can be understood that the maximum retractable amount of the pull cord 50 on the flywheel shaft 62 refers to the maximum amount that can be retracted on the flywheel shaft 62 based on the rotating member 12 at a certain rotational position (which can be but not limited to the initial position). The maximum length of the rope section, and when the main rope section of the maximum length is wound up on the flywheel shaft 62, the part that is not wound to the flywheel shaft 62 in the main rope section is in a taut state. In the structure shown in Fig. 1, the first rotation direction is indicated by arrow A.

It can be understood that the personal best training effect of the user's calf refers to: 1. During the user's heel raising exercise training process, the user's heel can be lifted to the highest height (that is, the user's heel can be lifted limit physiological height), and the user's calf is always subjected to the training resistance imposed by the counterweight flywheel 60 during the process of lifting the heel to the highest height; Rotational inertia immediately forms the training resistance for heel return training. The calf trainer can allow user groups with different heel lift heights to perform sitting calf raise training. The realization conditions for the above-mentioned personal best training effect are as follows: 1. When the rotating member 12 is at the initial position, the flywheel shaft 62 is at the maximum 2. When the user's heel is lifted to the highest height, the maximum rope coil wound on the flywheel shaft 62 is just completely released. Based on the above-mentioned realization conditions, user groups with different calf lifting heights can adjust the adapted maximum retractable amount through the adjusting device 70 to achieve the best personal training effect of the calf. In addition, the user can also adjust the maximum retractable amount to a specified amount through the adjusting device 70, so that the user can perform calf raising training at a specified calf lifting height.

Based on the above-mentioned realization conditions, the process for the user to perform heel raising training based on the best personal training effect is as follows: the user performs heel raising to lift the heel and calf, and the raised calf drives the leg pressing part 40 to move upward through the thigh , the upwardly moving pressing leg portion 40 drives the rotating member 12 to rotate from the initial position along the first rotating direction, the rotating rotating member 12 drives the counterweight flywheel 60 to rotate through the pull rope 50 and releases the pull rope 50 to wind on the flywheel shaft 62 to form When the user's heel is lifted to the highest height, the maximum rope volume on the flywheel shaft 62 is just fully released (at this moment, the heel-raising action ends and the heel-returning action begins), and after the maximum rope volume is fully released, the The heavy flywheel 60 continues to rotate under the effect of rotational inertia and immediately reverses the stay cord 50 through the flywheel shaft 62, and the flywheel shaft 62 drives the rotating member 12 to rotate along the second rotation direction when the flywheel shaft 62 winds the stay cord 50 in the reverse direction. The rotating part 12 drives the leg pressing part 40 to move down, and the descending leg pressing part 40 will be hindered by the user's thigh and slowly move down along with the user's calf and heel until the user's heel resets (heel back at this time) action ends). In the above-mentioned calf training process based on the best personal training effect, the user's heel can be lifted to the highest height when performing the heel raising action, and the user's calf is always contracted and exerting force during the whole process of the heel raising action. When the heel return action is performed, the rotational inertia of the counterweight flywheel 60 when the user's heel is lifted to the highest height forms the training resistance of the heel return action to the greatest extent, thereby achieving the best training effect on the calf.

In this embodiment, the maximum retractable amount of the pull cord 50 on the flywheel shaft 62 is adjusted by the adjusting device 70, which not only enables the flywheel type sitting posture calf trainer to be adapted and adjusted by each user according to the lifting height of his own calf. The maximum retractable amount of the rope 50 on the flywheel shaft 62 makes the flywheel-type sitting posture calf trainer able to satisfy each user's calf to achieve the best personal training effect, while the flywheel-type sitting posture calf trainer also It can satisfy the user to perform calf training at the designated calf lifting height, and improves the user experience of the flywheel-type seated calf trainer.

It can be understood that the normal position of the rotating member 12 when the calf trainer is not being used for calf raising training by the user is the initial position.
