Abstract
Description
Technical Field
[0001] This invention relates to the field of coordination training devices, specifically a two-hand coordination trainer. Background Technology
[0002] Currently, the fitness equipment market mainly focuses on equipment aimed at improving strength and cardiovascular function, while equipment aimed at improving upper limb coordination is virtually nonexistent. The simplest and most effective way to improve upper limb coordination is through the interplay of left and right hand movements. Therefore, this invention proposes a two-hand coordination trainer that not only improves hand coordination but also adds a lot of fun to fitness. Summary of the Invention
[0003] To address the aforementioned problems, this invention provides a two-handed coordination trainer.
[0004] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows: a two-hand coordination trainer, including a left shell and a right shell, both the left shell and the right shell are open on one side and detachably connected with a shell cover, the bottom surfaces of the left shell and the right shell are closely attached to each other and fixedly connected, a left ratchet is rotatably provided at the center of the bottom surface inside the left shell through a bearing, a left pawl is rotatably provided on the bottom surface inside the left shell, the left pawl matches the left ratchet, a spring is connected between the left pawl and the side wall of the left shell, and the left ratchet rotates counterclockwise;
[0005] A right ratchet is rotatably mounted on the center of the bottom surface inside the right housing via a bearing. A right pawl is rotatably mounted on the bottom surface inside the right housing. The right pawl matches the right ratchet. A second spring is connected between the right pawl and the side wall of the right housing. The right ratchet rotates clockwise. Both the left and right ratchet have a rotating handle.
[0006] Furthermore, the cover is provided with an annular through hole through which the rotating handle passes.
[0007] Furthermore, both the left and right shells are circular.
[0008] Furthermore, both the left and right housings have external threads at their openings, and the inner side of the cover has internal threads. The cover and the left or right housing are connected by threads.
[0009] The advantages of this invention compared to existing technologies are as follows: This invention proposes a two-hand coordination trainer, which not only improves hand coordination but also brings a lot of fun to fitness. The left and right ratchet wheels are connected by bearings, which increases the smoothness of use. The two-hand grip design increases stability, and the ratchet pawl structure can immediately lock when the user turns in the wrong direction, improving the accuracy of training.

[0017] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "center", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limiting this invention.
[0018] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "provided with," "installed," "connected," "linked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0019] The present invention will now be described in further detail with reference to the accompanying drawings.
[0020] 1. Combined with the appendix Figure 1 To be continued Figure 6A two-hand coordination trainer includes a left shell 1 and a right shell 2, both of which are circular. Each shell has one open side with a threaded cover 3. The bottom surfaces of the left shell 1 and right shell 2 are tightly fitted together and fixedly connected. A left ratchet 4 is rotatably mounted on the center of the bottom surface inside the left shell 1 via a bearing. A left pawl 5 is rotatably mounted on the bottom surface inside the left shell 1, matching the left ratchet 4. A spring 6 connects the left pawl 5 to the side wall of the left shell 1. The left ratchet 4 rotates counterclockwise.
[0021] The right housing 2 has a right ratchet 7 rotatably mounted on the center of its inner bottom surface via a bearing. The right pawl 8 is rotatably mounted on the inner bottom surface of the right housing 2. The right pawl 8 matches the right ratchet 7. A spring 9 is connected between the right pawl 8 and the side wall of the right housing 2. The right ratchet 7 rotates clockwise. Both the left ratchet 4 and the right ratchet 7 are provided with a rotating handle 10. The housing cover 3 is provided with an annular through hole 11 through which the rotating handle 10 passes.
[0022] Specific implementation of the present invention: When using the present invention, the left and right hands respectively hold the two rotating handles 10, the left hand rotates counterclockwise and the right hand rotates clockwise at the same time, so as to achieve the purpose of training the coordination ability of the left and right hands. When the left and right hands rotate in the wrong direction, the corresponding pawl will jam the ratchet, causing it to be unable to rotate, thus achieving the purpose of timely correction. The present invention not only trains the coordination of the hands, but also brings a lot of fun to fitness.
[0023] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
