Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a hand exercise device with an external counterweight. Background Art

[0002] With the progress of society, people's living standards are getting higher and higher. So people are gradually paying attention to health issues and starting to exercise. Due to the busy work schedule, more people choose to exercise at home. Therefore, various exercise equipment have begun to enter thousands of households. Among these exercise equipment, there are those that exercise the whole body, and those that exercise the arms, waist, back, legs, etc. Among them, those used to exercise the strength of the hands include: Flying Rod, Arm Strengthener, Gyro Wrist Ball, etc. However, whether it is Flying Rod, Arm Strengthener, Gyro Wrist Ball, etc., they all have the following problems:

[0003] 1. They are generally quite long. For example, a Flyx stick is approximately 150-160cm long, and even smaller arm trainers are generally around 60cm long. Even the smaller gyro wrist strength ball, due to the handle, is around 50cm long. Therefore, these exercise equipment are very bulky, making them difficult to store and pack. Especially during transportation, their slender shape can easily be squeezed or bumped by foreign objects, causing damage.

[0004] 2. Since the overall length of the Flying Rod is about 150-160CM, it will take up a lot of space when in use. Otherwise, it will easily hit people or objects around. Therefore, there are certain requirements for the use scene.

[0005] 3. Arm trainers and gyroscopic wrist strength balls are difficult for beginners with no prior training experience. Gyroscopic wrist strength balls are especially difficult to start and spin. Even with a starting aid, the gyroscopic wrist strength ball won't spin after the assistive start-up ends, thus failing to achieve the desired training effect. Utility Model Content

[0006] The present invention aims at solving the above problems and overcoming at least one of the drawbacks by providing a hand exercise device with an external counterweight.

[0007] The technical solutions adopted by this utility model are as follows:

[0008] A hand exercise device with an external counterweight includes a fixed portion and a rotating portion. The fixed portion is used to form a path, and the rotating portion rotates along the path. The fixed portion is provided with a hand-held portion; the rotating portion is provided with a counterweight portion outside.

[0009] When the counterweight part is swung, the counterweight part generates centrifugal force and drives the rotating part to rotate synchronously along the path.

[0010] In actual use, the user grasps the handle and shakes the rotating part. Because the rotating part is connected to the counterweight, the counterweight also swings. The swinging of the counterweight easily generates centrifugal force, which easily drives the entire rotating part. Continuous swinging of the counterweight maintains the rotating part's continuous rotation. As the duration of this exercise increases, it strengthens the user's hands.

[0011] Compared with existing exercise equipment, the presence of the counterweight makes the hand exercise device with an external counterweight very easy to use. Even users with no exercise experience, or users with weak arm strength such as women and children, can easily rotate the rotating part and maintain the rotation of the rotating part, thereby achieving the effect of exercising the hands.

[0012] Furthermore, the rotating portion is annular, with a diameter of approximately 25-30 cm. Therefore, the overall space occupied is significantly reduced compared to existing exercise equipment. This not only significantly reduces the requirements for the use of an externally weighted hand exercise device, but also makes it easier and more convenient to pack, store, and transport.

[0013] Moreover, compared with the slender exercise equipment in the prior art, the circular ring structure is more resistant to pressure and collision, making the whole body less likely to be damaged.

[0014] In one embodiment of the present invention, an annular cavity is provided inside the fixed portion, providing a path for the rotating portion to rotate. An opening is provided on one side of the fixed portion; the opening connects the cavity with the outside of the fixed portion.

[0015] In actual use, the setting of the opening facilitates assembly during the production process, and the counterweight part can be passed through the opening very simply, thereby being exposed outside the fixed part.

[0016] In one embodiment of the present invention, a cavity is provided inside the fixed portion and surrounds the fixed portion itself. The cavity is in the shape of a circular ring and provides a rotation path for the rotating portion.

[0017] An opening is provided on one side of the fixing portion away from its own center. The opening extends around the circumference of the fixing portion to form an opening in an overall circular shape. The opening connects the cavity with the outside of the fixing portion.

[0018] In actual use, the overall annular opening can ensure that the counterweight part exposed outside the fixed part can rotate smoothly around the fixed part, so that the counterweight part can continuously generate centrifugal force, thereby continuously driving the rotation of the rotating part.

[0019] In one embodiment of the present invention, the rotating portion is annular and accommodated in the cavity, and a counterweight portion is fixedly or detachably connected to the outside of the rotating portion.

[0020] The counterweight portion passes through the opening and is exposed outside the fixing portion.

[0021] When the counterweight part is swung, centrifugal force is generated and drives the rotating part to rotate in the cavity.

[0022] In actual use, the detachable counterweight part can be separated from the rotating part to facilitate the storage and transportation of the whole.

[0023] Moreover, the counterweight portion is arranged outside the rotating portion, which is easier to use and easier to drive the rotating portion to rotate than to arrange it inside the rotating portion. In particular, when the counterweight portion is exposed outside the fixed portion, the effect will be more obvious.

[0024] When the counterweight part that generates centrifugal force drives the rotating part to rotate, the counterweight part itself will revolve around the circumference of the fixed part.

[0025] In one embodiment of the present invention, the fixing portion is in the shape of a ring, and a handle portion is provided in the middle of the ring or in its axial direction; both ends of the handle portion are fixedly connected to the fixing portion.

[0026] During actual use, the handheld portion can be easily held by the user, thereby enabling the user to exercise the hands more effectively.

[0027] In one embodiment of the present invention, an accommodating chamber is provided on the inner wall of the cavity, and a power assisting device is provided in the accommodating chamber; the power assisting device abuts against the outer wall surface of the rotating part.

[0028] During actual use, the power assist device can help the rotating part to rotate more smoothly and smoothly along the path provided by the cavity, thereby avoiding the rotating part from getting stuck in the cavity.

[0029] In one embodiment of the present invention, the power assist device includes a fixed shaft, both ends of which are fixed in the accommodating cavity, and a roller is sleeved on the outer surface of the fixed shaft, and the roller abuts against the outer wall surface of the rotating part.

[0030] In actual use, the roller avoids direct contact between the outer wall of the rotating part and the inner wall of the cavity, thereby reducing the corresponding friction resistance and ensuring that the rotating part can rotate smoothly and fluently.

[0031] In one embodiment of the present invention, the power assist device includes a ball. The ball is accommodated in the accommodating cavity, and the ball abuts against the outer wall surface of the rotating part.

[0032] In actual use, the ball avoids direct contact between the outer wall of the rotating part and the inner wall of the cavity, thereby reducing the corresponding friction resistance and ensuring that the rotating part can rotate smoothly and fluently.

[0033] In one embodiment of the present invention, a counterweight cavity is provided outside the rotating portion, and the counterweight portion is accommodated inside the counterweight cavity;

[0034] When the rotating part rotates, the counterweight part moves synchronously with the rotating part.

[0035] In actual use, due to the limitation of the counterweight cavity, there will be no relative movement between the counterweight part and the rotating part, so that the two can only maintain synchronous movement, thereby ensuring that the counterweight part can smoothly drive the rotating part to rotate.

[0036] In one embodiment of the present invention, the counterweight portion is a counterweight block, a counterweight liquid, or a counterweight sand.

[0037] In actual use, the counterweight liquid is generally water. When an externally-weighted hand exercise device needs to be transported or stored, the water can be poured out first, thereby reducing its weight and making it easier to transport or store. When the externally-weighted hand exercise device needs to be used, water can be added, which is very convenient and simple.

[0038] The beneficial effects of this utility model are as follows: by providing a counterweight portion, an externally weighted hand exercise device is made easier to use, thereby expanding its user base. Furthermore, its overall size is relatively small, which not only facilitates packaging, transportation, and storage, but also reduces the space required during use, thereby expanding its scope of use. Furthermore, the circular ring-shaped structure makes the overall structure resistant to pressure, drop, and damage, thereby increasing its service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0044] In the description of this application, it should be noted that the terms "inner" and "outer" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first" and "second" and the like are used solely for distinction and should not be construed as indicating or implying relative importance.

[0045] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed" and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0046] The present invention will be described in detail below with reference to the accompanying drawings.

[0047] Example 1

[0048] like Figures 1 to 2 As shown, a hand exercise device with an external counterweight includes a fixed portion 1 and a rotating portion 2. The fixed portion 1 is used to form a path, and the rotating portion 2 is annular and rotates along the path. The diameter of the annular rotating portion 2 is approximately 25-30 cm. Therefore, the overall space occupied is significantly reduced compared to existing exercise equipment. This not only significantly reduces the requirements for the use scenario of a hand exercise device with an external counterweight, but also makes it easier and more convenient to pack, store, and transport.

[0049] Moreover, compared with the slender exercise equipment in the prior art, the circular ring structure is more resistant to pressure and collision, making the whole body less likely to be damaged.

[0050] The fixing part 1 is annular, with a hand-held part 3 in the middle or in its axial direction; both ends of the hand-held part 3 are fixedly connected to the fixing part 1. The hand-held part 3 is convenient for the user to hold, so that the user can exercise the hands more effectively.

[0051] A cavity 5 is provided inside the fixed part 1 and surrounds the center of the fixed part 1 . The cavity 5 is in the shape of a circular ring as a whole and provides a path for the rotation of the rotating part 2 .

[0052] An opening 8 is provided on one side of the fixing portion 1 away from its own center. The opening 8 extends around the circumference of the fixing portion 1 to form an overall annular opening 8 . The opening 8 connects the cavity 5 with the outside of the fixing portion 1 .

[0053] The provision of the opening 8 facilitates assembly during the production process, and the counterweight portion 4 can be easily passed through the opening 8, thereby being exposed outside the fixed portion 1. The generally circular opening 8 ensures that the counterweight portion 4 exposed outside the fixed portion 1 can smoothly rotate around the fixed portion 1, thereby allowing the counterweight portion 4 to continuously generate centrifugal force, thereby continuously driving the rotation of the rotating portion 2.

[0054] The rotating part 2 is accommodated in the cavity 5, and the counterweight part 4 is fixedly or detachably connected to the outside of the rotating part 2. After the detachable counterweight part 4 is separated from the rotating part 2, it is convenient for the overall storage and transportation.

[0055] or,

[0056] A counterweight cavity is provided on the outside of the rotating part 2, and the counterweight part 4 is accommodated inside the counterweight cavity. Due to the limitation of the counterweight cavity, there will be no relative movement between the counterweight part 4 and the rotating part 2, so that the two can only maintain synchronous movement. This ensures that the counterweight part 4 can smoothly drive the rotating part 2 to rotate. The counterweight part 4 is a counterweight block or a counterweight liquid or a counterweight sand. The counterweight liquid is generally water, but it can also be other liquids. When a hand exercise device with an external counterweight needs to be transported or stored, the water can be poured out first, which can reduce its own weight and make it more convenient to transport or store. When a hand exercise device with an external counterweight needs to be used, water can be injected, which is very convenient and simple.

[0057] The counterweight 4 passes through the opening 8 and is exposed outside the fixed portion 1. Placing the counterweight 4 outside the rotating portion 2 is easier to use and more easily drives the rotating portion 2 to rotate than placing it inside the rotating portion 2. The effect is particularly noticeable when the counterweight 4 is exposed outside the fixed portion 1.

[0058] When the counterweight 4 is swung, centrifugal force is generated and drives the rotating part 2 to rotate along the path in the cavity 5. At this time, the counterweight 4 itself will revolve around the circumference of the fixed part 1.

[0059] An accommodating chamber is provided on the inner wall of the cavity 5 , and a power assisting device is provided in the accommodating chamber; the power assisting device abuts against the outer wall surface of the rotating part 2 .

[0060] The power assist device includes a fixed shaft, both ends of which are fixed in the accommodating cavity, and a roller 6 is sleeved on the outer ring of the fixed shaft, and the roller 6 abuts against the outer wall surface of the rotating part 2.

[0061] or,

[0062] The power assist device includes a ball (not shown in the figure), which is accommodated in the accommodating cavity and abuts against the outer wall surface of the rotating part 2.

[0063] Whether it is the setting of the roller 6 or the setting of the ball, the contact area between the outer wall of the rotating part 2 and the inner wall of the cavity 5 can be reduced, thereby reducing the corresponding friction resistance, and then the rotating part 2 can rotate smoothly and fluently along the path in the cavity 5 when rotating.

[0064] During production, the fixed portion 1 and the handle portion 3 are integrally molded, and the entire assembly is divided into upper and lower sections. During assembly, the upper and lower sections are respectively placed over the upper and lower sides of the rotating portion 2 and secured together using clips or screws. The rotating portion 2 can be integrally molded separately or with the counterweight 4.

[0065] In actual use, the user first grasps the handheld portion 3 and then performs a small, circular shaking motion. Because the counterweight 4 is located outside the rotating portion 2, the counterweight 4 is swung, generating centrifugal force that drives the rotating portion 2 to rotate. At this point, the counterweight 4 itself orbits around the outside of the fixed portion 1. As the duration of this shaking motion increases, the user's hands become stronger.

[0066] Compared with existing exercise equipment, the presence of the counterweight portion 4 makes the hand exercise device with an external counterweight very easy to use and can easily drive the rotating portion 2 to rotate. Even users with no exercise experience, or users with weak arm strength such as women and children, can easily rotate the rotating portion 2 and maintain its rotation, thereby achieving the effect of exercising the hands.

[0067] The above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformation made by using the contents of the description and drawings of the present invention, directly or indirectly applied in other related technical fields, is also included in the scope of protection of the present invention.
