Description

Technical Field

[0001] The utility model belongs to the technical field of abdominal wheel structures for fitness, in particular to an elbow-supported abdominal wheel. Background Art

[0002] The ab wheel is a physical exercise device with a simple structure, easy use, and obvious effects. When exercising, kneel on your knees, hold the handles with both hands, and place the ab wheel in front of your body. You can use the ab wheel to do abdominal exercises at home, and the effect is much better than traditional sit-ups. In order to reduce the difficulty of operation for users, elbow-supported ab wheels have appeared on the market, such as Chinese patent 202223039061.8, a double-wheel elbow-supported ab wheel. This ab wheel uses elbow support to perform abdominal exercises, so that beginners can also get started. In fact, regardless of the above-mentioned ab wheel, in order to facilitate the user's exercise, the manufacturer will set a reset spring inside the wheel body of the ab wheel to help the user complete the exercise.

[0003] For example, Chinese patent CN202322589608.X discloses an easy-to-assemble abdominal wheel, comprising a pulley seat, a handle assembly, and a pulley assembly. The pulley seat is provided with an elbow support plate, and the bottom of the pulley seat is provided with a plurality of interlaced reinforcing ribs, with a plurality of fixing grooves formed between the reinforcing ribs; the handle assembly is connected to the pulley seat; the pulley assembly comprises a pulley and a pulley connecting plate for fixing the pulley, and the pulley connecting plate is clamped in the fixing groove. This product provides a double-wheeled abdominal wheel to improve structural stability, but this product still has shortcomings: not all wheel bodies are equipped with a reset spring. The manufacturer installs a reset spring in one wheel body to provide reset force to reduce the difficulty of use for the user. The abdominal wheel is generally used in a kneeling position, with the user's elbows placed on the elbow support plate and the hands grasping the handles. It is impossible to maintain a very standard horizontal state during the forward or backward movement, so the hands or elbows will be in an upturned state, which is manifested in the front or rear wheel of the abdominal wheel leaving the ground, and the wheel body that leaves the ground will lose its supporting force. Once the wheel body with a reset spring leaves the ground, the reset spring fails, and the user will suddenly lose a reset force or resistance. The user may fall, and the user's experience will also be greatly affected. Summary of the Invention
