Detailed ways

Please refer to FIG. 1 to FIG. 6 , which are respectively a perspective view, a left side view and an actuating state view of a preferred embodiment of the seat-type stepper provided by the present invention. In addition, the front and rear directions in this article correspond to the direction cognition of the user in the use state.

As shown in each figure, the seat type stepper 1 mainly includes:

A skeleton 10, the skeleton 10 has a seat portion 12, a track portion 14 and a left and right crank 20 corresponding to each other. The left and right cranks 20 of the embodiment of the present invention are arranged below the seat portion, and each of the cranks 20 has a single end at one end. To the bearing 22.

A transmission mechanism 30 is pivotally arranged on the framework 10 and arranged under the seat portion 12. The transmission mechanism 30 includes a pulley 32 and a flywheel 34 co-moving. The pulley 32 is combined with the crank 20 by the one-way bearing 22 catch. The synchronous action of the flywheel 34 and the pulley 32 is well known in the industry, and will not be described in the embodiments of the present invention.

A pair of stepping connecting rod groups 40, each of which stepping connecting rod groups 40 is connected to one end of the left and right cranks 20. The stepping connecting rod group 40 includes a swing tube 42, a pair of pedal rods 44, and a pedal 46 With a sliding wheel 48, one end of the swing tube 42 is pivotally arranged below the seat portion 12, and the other end is connected to one end of the pedal bar 44 and extends toward the track portion 14; the other end of the pedal bar 44 is provided with the pedal 46 and The sliding wheel 48, the sliding wheel 48 can make the pedal 46 displace along the track portion 14 and make the pedal bar 44 move back and forth. The knot 422 is engageable with one end of the corresponding crank 20 .

Please refer to FIG. 3 to FIG. 6, respectively, when the user sits on the seat portion 12 and steps on the pedal 46, the sliding wheel 48 moves on the track portion 14 through one of the user’s feet, and the sliding wheel 48 moves in phase. The connected pedal 44 will also be displaced forward relative to the sliding wheel 48. At this time, one end of the swing tube 42 connected to the pedal 44 is also pulled forward, and is pivotally connected to the pivot joint 422 of the swing tube 42. The crank 20 will be driven to rotate. When the crank 20 rotates, the one-way bearing 22 drives the pulley 32 of the transmission mechanism 30 to rotate, and the pulley 32 also synchronously drives the flywheel 34 of the transmission mechanism 30 to rotate.

When the other foot exerts force, due to the inertia of the flywheel 34, it can easily exert force, and the force applied during the movement of the user's feet can be smooth, and the user's footsteps can be smooth and linear. And because the crank 20 and the pulley 32 are combined through the one-way bearing 22, two objects that rotate independently at different speeds can be separated or combined to achieve the combination or separation of the two objects with mechanical functions. Therefore, the user's feet can adjust the exercise demand and physical load status at any time, adjust the stride length or change the direction of force application at any time, without causing injury. To further illustrate, it can provide the user with the stepping action in the middle, when the foot has not stepped to the predetermined position, and suddenly needs to suspend the stepping action, or stop or use another foot to apply force. At this time, the one-way bearing provides the crank 20 to rotate independently from the belt pulley 32 and the flywheel 34 of the transmission mechanism, so as to maintain the free control state of the user's feet without being affected by the transmission mechanism.

Please refer to Fig. 7, the present invention adds handrail. According to the needs of users, the present invention can add handrails 80 to the position adjacent to the track portion 14 of the above-mentioned seat-type stepper 1 for users to use in a variety of ways. The user can use the gentle stepping action of both feet to cooperate with the rhythmic movement of both hands in the sitting position. Increasing the changes during exercise can make the user willing to use and exercise for a long time.

Based on the above description, it can be seen that the seated stepper 1 provided by the present invention can provide the user with a sitting posture to achieve the purpose of exercise through the pedaling action of both feet, and can adjust the pedaling stride size at any time during the pedaling process. From this, you can adjust it according to your own needs to meet your physical state, joint and muscle state. The user can stop the stepping action at any time, and cooperate with the transmission mechanism to provide a stable and smooth stepping force application, which avoids the burden on the user's body and provides a gentle force application movement.
