Description

A folding stool and electronic resistance band compatible with resistance bands Technical Field

[0001] This utility model relates to the field of tensioner technology, and in particular to a folding stool adapted to a tensioner and an electronic tensioner. Background Technology

[0002] Chinese Patent (Announcement No.: CN209361747U) discloses a novel silent vibrating fitness device, comprising a vibrating motor; the eccentric plate of the vibrating motor includes a moving plate and a stationary plate, with a bolt hole at one end of the stationary plate; semi-circular notches are formed at both ends of the moving plate corresponding to the bolt holes of the stationary plate; it also includes an annular rubber column; strip-shaped protrusions are evenly distributed on the outer side of the annular rubber column; the annular rubber column is bolted onto the bolt hole, corresponding to the height of the semi-circular notch. By using a specially designed annular rubber column, the moving plate and stationary plate reduce impact noise and vibration sensation when the motor starts or stops, reducing user psychological aversion and physical discomfort. At the same time, the overall size and weight of the machine are reduced, making it more convenient for home use. Furthermore, through improvements to various components, the overall noise during operation is reduced, ensuring that it will not cause excessive noise even when used in a small environment.

[0003] As a type of fitness equipment, the aforementioned resistance bands and existing resistance bands are small in size and easy to use, and are gradually gaining popularity among fitness enthusiasts. However, these resistance bands have limited usage methods and relatively simple exercise modes, failing to meet the needs of users who want to exercise different body parts. Furthermore, these resistance bands are not easy to secure and have limited applicability, hindering their widespread adoption.

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a folding stool and electronic resistance band that are adapted to resistance bands, and to provide a rotatable resistance arm that fixes the resistance band, so as to enable a variety of exercise postures in conjunction with the resistance band.

[0006] The second objective of this invention is to provide a folding stool and electronic resistance band compatible with resistance bands. It features a rotatable and foldable first support member, a second support member, a mounting base, and a seat. When the first and second support members are unfolded, they form a support frame that can secure the electronic resistance band and support the user's weight, facilitating resistance training. Simultaneously, the mounting base secures the electronic resistance band, ensuring its stability, safety, and reliability, allowing for the training of different body parts and a variety of postures. Furthermore, when the first and second support members are folded, the size of the folding stool is effectively reduced, making it easy to store and carry, suitable for various training scenarios, and providing a good user experience.

[0007] The third objective of this invention is to provide a folding stool and electronic resistance band adapted to a resistance band. The resistance band is fixed to a rotatable resistance arm, and the resistance arm can be fixed in multiple positions on the backrest assembly, thus allowing for the exercise of different parts of the user's body and a variety of exercise postures. Furthermore, fixing the resistance arm in different positions, combined with the rotatable and adjustable seat and backrest assemblies, makes the exercise postures even more diverse. The resistance arm, seat, and backrest assemblies can all rotate, making the multifunctional folding stool smaller in size after folding and easier to store.

[0008] To achieve one of the above objectives, the first technical solution of this utility model is as follows:
