Description

Technical Field

[0001] The present application relates to the technical field of fitness equipment, and particularly to a coccyx limiting device and a leg curl trainer. Background Art

[0002] A leg curl trainer is a fitness equipment designed specifically for exercising the hamstrings (back of the thighs) and calf muscles. By simulating the leg bending movement, it enhances the muscle strength and endurance of the hamstrings at the back of the thighs, calf muscles, buttocks, and the front of the thighs.

[0037] Please refer to Figures 1 to 2 , in the first embodiment of the present application, a coccyx limiting device 10 is proposed for a leg curl trainer 20. The leg curl trainer 20 is provided with a longitudinal beam 21 and a backrest 22. When a user uses the leg curl trainer 20, the user lies prone on the backrest 22. The coccyx limiting device 10 is fixed on the longitudinal beam 21 through a support member 11, and a limiting member 12 and a lifting assembly 13 are connected through the support member 11. When the user starts the leg curl training, the buttocks may involuntarily lift due to uneven force distribution or improper body control. The operator adjusts the rotating member 132 so that the abutting member 133 can accurately abut against the coccyx position of the user, providing stable support to prevent the buttocks from lifting. The supporting force is transmitted to the coccyx position through the abutting member 133 to ensure that the user maintains the correct posture during the training process. The support member 11 and the limiting member 12 ensure that the coccyx limiting device 10 remains stable during the training process and will not shake or shift due to the user's actions. Through the action of the coccyx limiting device 10, the user can perform leg curl training more effectively, avoid the lumbar spine pressure and injury risk caused by incorrect postures, and improve the training effect and safety.

[0038] Please refer to Figure 1, in some embodiments, the coccyx limiting device 10 includes a support member 11, a limiting member 12, and a lifting assembly 13; the support member 11 is detachably disposed on the longitudinal beam 21, which facilitates installation or disassembly by the user according to needs. The support member 11 is perpendicular to the longitudinal beam 21, thereby ensuring the stability and supporting force of the support member 11; the limiting member 12 is used to cooperate with the lifting assembly 13 to further limit the position of the user's coccyx. The limiting member 12 is fixedly disposed on the support member 11, thereby providing the necessary limiting force for the lifting assembly 13; the lifting assembly 13 is disposed on the limiting member 12, and the lifting assembly 13 is used to abut against the position of the user's coccyx, so that the position of the user's coccyx can be effectively limited, preventing the buttocks from being involuntarily lifted during training, and ensuring the correctness and effectiveness of the training action; wherein, the lifting assembly 13 is disposed above the backrest plate 22, which can accurately abut against the position of the user's coccyx, improving the pertinence of training and avoiding the lumbar spine pressure and injury risk caused by incorrect postures.

[0039] Please refer to Figure 1 , in some embodiments, the limiting member 12 includes a long arm section 121, a bent section 122, a short arm section 123, and a contraction section 124, which enables the limiting member 12 to have good structural strength and stability and can effectively resist the forces generated during training; the long arm section 121 is used to provide support for the bent section 122, and one end of the long arm section 121 is fixedly connected to the support member 11; the bent section 122 is used to change the direction of the short arm section 123 so that the short arm section 123 can be parallel to the transverse direction of the backrest plate 22, and one end of the bent section 122 is fixedly connected to the other section of the long arm section 121; the short arm section 123 is used to provide support for the contraction section 124, and one end of the short arm section 123 is fixedly connected to the other end of the bent section 122; the contraction section 124 is used to adjust the transverse length of the lifting assembly 13 at the position of the backrest plate 22, thereby ensuring that the position of the lifting assembly 13 adapts to the coccyx positions of different users. The contraction section 124 is detachably connected to the other end of the short arm section 123, and the other end of the contraction section 124 is used to install the lifting assembly 13, so that the length of the limiting member 12 is adjustable, can flexibly adapt to the body type requirements of different users, and provides personalized training support.

[0040] Please refer to Figures 1 to 2, in some embodiments, the contraction section 124 has a number of socket members 1241. The number of socket members 1241 are sleeved in sequence, and each socket member 1241 is designed to be nested with each other, so as to allow the user to adjust the length of the contraction section 124 as needed. A lifting hole 1242 is formed in the socket member 1241 away from the bending section 122. The lifting hole 1242 is used to fix the lifting assembly 13, thereby ensuring that the lifting assembly 13 can be stably fixed.

[0041] Please refer to Figure 3 , in some embodiments, the length of the contraction section 124 in the non-contracted state is 1 / 4 to 2 / 3 of the lateral length of the backrest plate 22. This not only ensures that the contraction section 124 has sufficient adjustment space, but also avoids redundancy and inconvenient storage caused by the excessive length of the contraction section 124.
