Description

Technical Field

[0001] This invention relates to the field of fitness equipment, and more specifically, to a pneumatic folding fitness device. Background Technology

[0002] With the popularization of the national fitness concept, home fitness equipment has gradually become an important choice for family exercise due to its advantages such as ease of use and lack of space restrictions. Among them, upper limb training equipment, as the core equipment for targeted training of arm, shoulder, and back muscles, directly affects the user experience and training results due to its reasonable structure, functional diversity, and space adaptability.

[0003] Weighted equipment typically uses iron blocks and counterweights as the load source, and achieves upper limb stretching training through ropes and pulleys. However, the counterweights are large and heavy, resulting in a bulky overall structure that is inconvenient to move and takes up a lot of home storage space, making it difficult to adapt to the needs of small apartments. Adjusting the counterweights relies on manually adding or removing counterweights, which is cumbersome. The impact of the counterweights can also generate noise, affecting the living environment.

[0004] Most existing upper limb training equipment has a fixed, integrated structure, lacking folding and storage capabilities. When not in use, it occupies a large amount of space, further reducing its applicability in small apartments. Although some equipment includes training seats, these seats are mostly fixed structures, unable to be flexibly adjusted according to the user's height and training posture, and cannot be folded for storage. The upper limb training structures of existing equipment are mostly based on a single transmission method, with fixed training angles and postures, unable to realize a variety of upper limb training movements, resulting in limited functionality and difficulty in comprehensively exercising all parts of the upper limb muscles, thus failing to meet the diverse training needs of users. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the above-mentioned traditional technologies and provide a pneumatic folding fitness device with a foldable bench that can use a pneumatic cylinder as a load and can adjust the training bar as needed.

The position of the training grip and the training trajectory can be flexibly adjusted according to training needs, meeting personalized training requirements. By using a main transmission component, secondary transmission component, and load-bearing component, traditional counterweights or elastic components are replaced. The output resistance of the pneumatic cylinder can be steplessly adjusted, precisely adapting to users of different training levels. This avoids the problems of fixed counterweight positions and elastic decay of elastic components. Operating noise is extremely low; there is no counterweight impact noise during pneumatic cylinder operation, making it suitable for quiet home environments. The structure is compact and lightweight. Compared to traditional counterweight equipment, the pneumatic load-bearing structure is smaller and lighter, significantly reducing the overall bulkiness of the equipment, making it easy to transport and install. Training safety is high; the pneumatic cylinder has excellent cushioning performance, effectively preventing muscle strain caused by sudden changes in resistance during training. Simultaneously, the traction component, combined with a return spring, enables smooth recovery after training, further enhancing training safety. The specially designed folding stool component allows for easy folding upwards when not in use, fitting snugly against the main frame and significantly reducing the space occupied by the equipment. The inclined support legs, working in conjunction with the leg-fixing rods, enable quick unfolding and locking of the folding stool component. When unfolded, it offers strong stability, meeting the seated posture requirements during training. When folded, it is easy to store, solving the problems of existing equipment's inability to fold and its high space consumption. Integrating the upper limb training components, weight-bearing components, and folding stool component into one unit eliminates the need for additional training equipment, providing a complete upper limb workout. Its high degree of functional integration saves space in the home gym. Attached Figure Description
