Abstract
Description
Technical Field
[0001] This application relates to the field of fitness equipment, and in particular to a hand grip strengthener. Background Technology
[0002] A hand grip strengthener, also known as an arm grip or finger grip strengthener, is a small fitness device used to exercise the strength of the wrists and arms. It is popular because it is small, lightweight, portable, and allows for practice without time or space constraints.
[0003] Traditional hand grip strengtheners typically consist of a torsion spring and two handles. One end of each handle is fixed to the torsion spring, while the other end extends away from the spring to form an angle. The distance between the ends of the two handles is the grip width during the grip's closing stroke. Users can close the grip by squeezing the handles with one or both hands to achieve their training goals. However, the grip width of traditional hand grip strengtheners is usually fixed. Therefore, for users with small hands or hand injuries that prevent them from fully opening their hands, single-handed grip training is often not possible, limiting the applicability of hand grip strengtheners. Summary of the Invention
[0004] This application provides a grip strengthener that allows for adjustable grip width, thus expanding the applicability of the grip strengthener.
[0005] The first aspect of this application provides a hand gripper, comprising:
[0006] Elastomers
[0007] The first grip portion and the second grip portion are connected at one end to the elastic body and at the other end to extend away from the elastic body to form a free end. The first grip portion and the axis of the second grip portion form an angle. When the angle changes, the elastic body undergoes elastic deformation. The second grip portion is provided with an adjustment hole.
[0008] An axial rod, one end of which is connected to the first grip, and the other end extends in the direction of the second grip to pass movably through the adjustment hole;
[0009] A locking element is available to be locked at different positions on the axial rod to abut or unlock the second grip, the locking element abutting the side of the second grip away from the first grip.
[0010] In some embodiments, the axial rod is threaded, and the locking element includes a nut that is threadedly fitted to the axial rod.
[0011] In some embodiments, the locking element further includes a safety block that is threaded to the axial rod and located on the side of the nut away from the second gripping portion, the safety block having both an axial and radial dimension larger than the nut.
[0012] In some embodiments, the axial rod is detachably assembled with the first grip.
[0013] In some embodiments, the first gripping part has an assembly hole, and the gripping device further includes a limiting block connected to the axial rod. The axial rod is movably inserted into the assembly hole. When the axial rod is locked with the locking member, the limiting block abuts against the side of the first gripping part away from the second gripping part.
[0014] In some embodiments, the axial rod is connected to both the first grip and the second grip via spherical bearings.
[0015] In some embodiments, the elastomer is a torsion spring, and the first gripping portion and the second gripping portion are fixedly connected to the torsion spring.
[0016] In some embodiments, both the first grip portion and the second grip portion have anti-slip textures on their surfaces.
[0017] Analysis shows that the hand gripper provided by this utility model, by setting an axial rod and a locking member, can change the included angle between the first and second gripping parts by abutting the second gripping part against different positions of the axial rod, thereby adjusting the distance between the free ends of the first and second gripping parts. This makes the grip distance of the hand gripper adjustable, so that the hand gripper can be used by people with different needs, thus expanding the application range of the hand gripper.

[0026] This application provides a hand gripper that can be used by users to train the strength of their wrists or arms.
[0027] Please see Figure 1-2 In one embodiment, the gripper includes an elastomer 1, a first grip portion 2, a second grip portion 3, an axial rod 4, and a locking member 5.
[0028] Specifically, both the first gripping part 2 and the second gripping part 3 are connected to the elastic body 1 at one end, and extend away from the elastic body 1 at the other end to form a free end. The two axes containing the first gripping part 2 and the second gripping part 3 form a non-zero included angle. When an external force is applied that causes this included angle to change, the elastic body 1 will undergo elastic deformation. An adjustment hole 31 is provided on the second gripping part 3. One end of the axial rod 4 is connected to the first gripping part 2, and the other end extends towards the second gripping part 3, thus movably passing through the adjustment hole 31. The locking member 5 can be locked at different positions on the axial rod 4 to abut against or unlock the second gripping part 3. The locking member 5 abuts against the side of the second gripping part 3 away from the first gripping part 2.
[0029] The hand gripper provided in this embodiment, by setting an axial rod 4 and a locking member 5, allows the second gripping part 3 to abut against different positions on the axial rod 4, thereby changing the included angle formed by the axes of the first gripping part 2 and the second gripping part 3, and thus adjusting the distance between the free ends of the first gripping part 2 and the second gripping part 3, i.e., the grip distance. In other words, when a user wants to use the hand gripper provided in this embodiment for grip strength training, they can first lock the locking member 5 to a suitable position on the axial rod 4 according to their hand size. Under the abutment of the locking member 5, the maximum open distance between the first gripping part 2 and the second gripping part 3 is limited to fit the user's hand shape without affecting the opening and closing of the hand gripper. Then, by gripping the first gripping part 2 and the second gripping part 3, the two can be brought closer or further apart to achieve the training purpose. Such a hand gripper can be used by people with different needs, expanding the applicability of hand grippers and benefiting people with special needs.
[0030] Please continue reading. Figure 1 In one embodiment, the elastic body 1 is a torsion spring. Both the first grip portion 2 and the second grip portion 3 are directly connected to the torsion spring at one end, and the other end extends away from the torsion spring to form a free end grip. That is, the first grip portion 2 and the second grip portion 3 are connected only by the torsion spring. This design allows the grip strengthener to be easily manufactured using a single material in one piece, making production easier and resulting in a simple and practical structure. In other embodiments, the elastic body 1 can also be a compression spring. In this case, one end of the first grip portion 2 and the second grip portion 3 are hinged together, and the other end is a free end. One end of the compression spring is connected to the first grip portion 2, and the other end is connected to the second grip portion 3. That is, the first grip portion 2, the second grip portion 3, and the compression spring cooperate to form an "A" shape. It is understood that whether the elastic body 1, the first grip portion 2, and the second grip portion 3 are directly or indirectly connected is not limited, as long as the connection method satisfies the basic function of the grip strengthener.
[0031] Please continue reading. Figure 1In one embodiment, the axial rod 4 is threaded, and the locking member 5 includes a nut 51 that can be threadedly engaged with the axial rod 4. This arrangement allows the locking or unlocking of the locking member 5 and the axial rod 4 to be achieved through a threaded engagement, making the grip adjustment of the grip strength device simpler and more convenient. Furthermore, the nut 51 can be locked at any point on the threaded section of the axial rod 4, allowing for finer adjustment precision and wider applicability of the grip strength device. In other embodiments, the locking member 5 and the axial rod 4 can also be locked through a detachable snap-fit mechanism. For example, snap-fit holes can be equidistantly provided on the axial rod 4, and the locking member 5 includes a locking block. The engagement of the locking block within different snap-fit holes allows for adjustment of the contact area of the second gripping part 3.
[0032] Please continue reading. Figure 1 In one embodiment, the locking member 5 further includes a safety block 52. The safety block 52 is also threaded onto the axial rod 4, and is located on the side of the nut 51 away from the second grip portion 3. The axial and radial dimensions of the safety block 52 are both larger than those of the nut 51. The safety block 52 further enhances the blocking effect on the second grip portion 3, thereby making the grip distance adjustment of the hand gripper more stable.
[0033] Please continue reading. Figure 1 In one embodiment, the axial rod 4 and the first grip portion 2 are detachably assembled. This configuration allows users who do not need to adjust the grip width of the grip strengthener to remove the axial rod 4 and locking member 5 during training, thereby preventing either the axial rod 4 or the locking member 5 from interfering with their use of the grip strengthener. In other embodiments, the axial rod 4 and the first grip portion 2 may be fixedly connected to prevent the axial rod 4 from being lost. It is understood that the specific connection method between the axial rod 4 and the first grip portion 2 is not limited.
[0034] Please continue reading. Figure 1-2 In one embodiment, an assembly hole 21 is provided on the first gripping part 2, and the gripping device also includes a limiting block 6. The axial rod 4 can be simultaneously movably inserted into the assembly hole 21 and the adjustment hole 31. The limiting block 6 is connected to the axial rod 4, and when the axial rod 4 is simultaneously inserted into the assembly hole 21 and the adjustment hole 31, the limiting block 6 abuts against the side of the first gripping part 2 away from the second gripping part 3.
[0035] This configuration allows the axial rod 4 to be inserted into the mounting hole 21 and the adjustment hole 31 only when the grip distance of the gripper needs to be adjusted, so that the limiting block 6 abuts against the first gripping part 2. Then, the locking member 5 is locked in the appropriate position of the axial rod 4 and abuts against the second gripping part 3, thereby ensuring that the grip distance meets the user's needs and making the operation simple and convenient.
[0036] Please continue reading. Figure 1In one embodiment, the axial rod 4 is connected to both the first gripping part 2 and the second gripping part 3 via spherical bearings. This facilitates the movement of the first gripping part 2 and the second gripping part 3 on the axial rod 4.
[0037] Please see Figure 2 In one embodiment, the mounting hole 21 is located at the tail end of the free end of the first gripping part 2, and the adjustment hole 31 is located at the tail end of the free end of the second gripping part 3. This reduces the impact on the use of the grip strengthener. It is understood that in other embodiments, the specific locations of the mounting hole 21 and the adjustment hole 31 are not limited.
[0038] Please continue reading. Figure 2 In one embodiment, both the first grip portion 2 and the second grip portion 3 are provided with anti-slip textures on their surfaces.
[0039] The above descriptions are merely some embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
