Description

Technical Field

[0001] This invention belongs to the field of grip strengthener technology and relates to a silicone-encased ring-shaped elastic frame pressure-adjustable grip strengthener. Background Technology

[0002] As a commonly used fitness equipment for hand strength training, hand grippers are mainly divided into three categories in the current mainstream market: R-type hand grippers, V-type hand grippers, and square frame hand grippers.

[0003] Among them, R-type and V-type hand grips, due to their structural design characteristics, cause the user's grip angle to continuously change with gripping movements during actual use. This results in significant differences in pressure on different parts of the hand, such as the palm, base of the fingers, and fingertips, making it impossible to achieve balanced force and comprehensive training of the hand muscles. This can easily lead to over-training or under-training in certain areas, affecting training effectiveness. While square-frame hand grips offer some improvement in grip angle stability, most use an all-metal frame structure. Pressure adjustment requires replacing the spring, which is cumbersome and inconvenient to disassemble and assemble. Furthermore, the sliding rail components are prone to wear and tear due to friction during long-term use, shortening the product's lifespan and affecting smoothness of use. Regardless of whether it's an R-type, V-type, or square-frame hand grip, the use of all-metal materials makes the product relatively bulky and inconvenient to carry.

[0004] Therefore, there is an urgent need to develop a hand gripper that can achieve balanced hand force distribution, convenient pressure adjustment, and is small and portable, so as to meet users' needs for efficient and comfortable hand training. Summary of the Invention

[0005] This invention provides a silicone-wrapped ring-shaped elastic frame pressure-adjustable grip strengthener, aiming to solve the problems of uneven force distribution, bulkiness and inconvenience in carrying, and cumbersome pressure adjustment operation of existing grip strengtheners.

Detailed Implementation

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] To achieve the above objectives, embodiments of the present invention provide a silicone-wrapped annular elastic frame pressure-adjustable gripper, see reference. Figure 1-10 As shown, it includes:

[0035] The symmetrical closed annular elastic bearing mechanism 1 comprises an upper bearing plate 2 and a lower bearing plate 3 arranged in parallel and opposite directions, and a steel spring sheet 4 arranged symmetrically on the left and right. Both ends of the steel spring sheet 4 are fastened to the ends of the upper bearing plate 2 and the lower bearing plate 3 by fasteners 13. The vertical axes of the upper bearing plate 2 and the lower bearing plate 3 are collinear. The elastic deformation direction of the steel spring sheet 4 is consistent with the compression and opening directions of the upper bearing plate 2 and the lower bearing plate 3, forming an annular force transmission path with symmetrical upper and lower forces.

[0036] The equal pressure adjustment mechanism 11 includes left and right symmetrical pressure generating elements 6. The upper and lower ends of the pressure generating elements 6 are respectively used to detachably engage with the middle of the upper pressure plate 2 and the lower pressure plate 3. The vertical axis of the pressure generating elements 6 is parallel to the compression and opening direction of the upper pressure plate 2 and the lower pressure plate 3. The initial vertical distance of the annular elastic bearing mechanism 1 is smaller than the vertical engagement distance of the pressure generating elements 6.

[0037] The integrated protective covering mechanism 5 is made of flexible material. The integrated protective covering mechanism 5 is integrally bonded to the annular elastic bearing mechanism 1 through a molding process, and completely fits and covers the entire area of ​​the annular elastic bearing mechanism 1 except for the mounting surface of the pressure generating component 6.

[0038] In this embodiment, the annular elastic bearing mechanism 1 adopts an upper pressure plate 2, a lower pressure plate 3, and left and right symmetrical rigid spring pieces 4 to form a closed, symmetrical structure, creating a stable and balanced force transmission path. The upper pressure plate 2 and the lower pressure plate 3 are collinear in vertical axis, ensuring that the pressure can be uniformly transmitted vertically when the hand is gripping. The rigid spring pieces 4 are made of manganese steel, and their elastic deformation direction is consistent with the compression and opening directions of the upper pressure plate 2 and the lower pressure plate 3. This provides basic rebound force for the hand gripper and ensures that the upper pressure plate 2 and the lower pressure plate 3 always move in parallel through symmetrical deformation, avoiding tilting that would cause excessive force concentration on the hand. At the same time, the high strength of manganese steel can improve the overall durability of the mechanism and prevent plastic deformation over long-term use. The integrated protective covering mechanism 5 is made of flexible material, which is more comfortable and provides a better experience during hand gripping. The detachable pressure generating component 6 can adjust the pressure according to training needs, making it highly adaptable.

[0039] Further reference Figure 4 , Figure 8 and Figure 9 As shown, the rigid spring 4 includes an upper flat part 7, a lower flat part 8 and an arc-shaped part 9. The upper flat part 7 and the lower flat part 8 are connected by the arc-shaped part 9. The rigid spring 4 has fixing holes 10 at both ends. The rigid spring 4 is made of spring steel and forms a compressive and opening elastic force.

[0040] In this embodiment, the rigid spring 4 is connected by an arc-shaped part 9. The arc-shaped connection design can avoid stress concentration and is the key to optimizing elastic deformation and force transmission. Compared with the right-angle connection structure, it can disperse the local stress under force to the entire surface of the rigid spring 4, extending the service life of the spring. At the same time, the outward elasticity characteristic allows the ring elastic bearing mechanism 1 to maintain a stable ring shape in its natural state. When the hand applies gripping force, the arc-shaped part 9 of the rigid spring 4 deforms inward, causing the upper bearing plate 2 and the lower bearing plate 3 to move closer smoothly, ensuring that the force transmission process is smooth and the rebound force is released evenly, improving training comfort.

[0041] Furthermore, both ends of the upper bearing plate 2 are provided with upper mounting holes 28, and both ends of the lower bearing plate 3 are provided with lower mounting holes 12. The fixing holes 10 are fastened to the upper mounting holes 28 and the lower mounting holes 12 respectively by fasteners 13, ensuring the structural stability of the annular elastic bearing mechanism 1. The hole alignment design can ensure that the connection position of the rigid spring sheet 4 with the upper bearing plate 2 and the lower bearing plate 3 is symmetrical, further ensuring the balance of force.

[0042] Further reference Figure 4 and Figure 6 As shown, the upper pressure plate 2 is provided with an upper folded reinforcing edge 14 and a lower folded anti-detachment edge 15 on both sides of the longitudinal direction, and the lower pressure plate 3 is provided with an upper folded anti-detachment edge 16 and a lower folded reinforcing edge 17 on both sides of the longitudinal direction. Several assembly strip holes 18 are symmetrically arranged in the middle of the upper pressure plate 2, and several assembly holes 19 are symmetrically arranged in the middle of the lower pressure plate 3. A bending baffle 20 is integrally connected to the bottom edge of the assembly hole 19. The assembly strip holes 18 correspond to the assembly holes 19 and are centered.

[0043] In this embodiment, the sheet metal bending process is used to design the folded edges on both sides of the upper pressure plate 2 and the lower pressure plate 3, which can improve the bending strength of the upper pressure plate 2 and the lower pressure plate 3 and prevent the upper pressure plate 2 and the lower pressure plate 3 from bending laterally when under compression. This ensures the stable assembly position of the pressure generating component 6. The symmetrical and centered arrangement of the assembly strip hole 18 and the assembly hole 19 can ensure that the pressure generating components 6 are evenly distributed in the middle of the upper pressure plate 2 and the lower pressure plate 3, so that the force on each pressure generating component 6 is consistent and avoids excessive local pressure caused by the misalignment of the assembly position. The bending baffle 20 of the assembly hole 19 can help the assembly hole 19 to hold the end clamp 23 of the pressure generating component 6.

[0044] Of course, in an alternative embodiment, the lower anti-detachment edge 15 and the upper anti-detachment edge 16 can also be designed as reinforced edges, which does not affect the use; and after increasing the thickness of the lower bearing plate 3, the wall thickness of the mounting hole 19 is also increased, so the end clamping part 23 of the pressure generating element 6 can be locked without the bending baffle 20, and the bending baffle 20 can be removed to reduce the bending process.

[0045] Further reference Figure 4 and Figure 8 As shown, the pressure generating element 6 consists of several pressure springs. The pressure springs are symmetrical integral structures. Each pressure spring is an integral structure consisting of an arc-shaped ring 21, a V-shaped locking part 22, an end locking part 23, and a connecting arm 24. The two ends of the arc-shaped ring 21 are integrally connected to the V-shaped locking part 22 and the end locking part 23 through the connecting arm 24. The V-shaped locking part 24 is used to engage with the mounting strip hole 18, and the end locking part 23 is used to engage with the mounting hole 19.

[0046] In this embodiment, the arc-shaped ring 21, as a ring structure, can uniformly release the elastic force in the vertical direction. Compared with the traditional cylindrical helical spring, which is prone to bulging deformation in the middle during compression, the arc-shaped ring 21 only has vertical deformation direction which is easier to control, thus avoiding left and right deviation during compression. The V-shaped locking part 22 uses the side of the V-shaped structure to form a surface contact locking with the inner edge of the mounting strip hole 18 of the upper pressure plate 2, ensuring that the upper part of the pressure generating element 6 is firmly connected and cannot rotate. The end locking part 23 is sleeved with the mounting hole 19 of the lower pressure plate 3. The connecting arm 24 evenly transmits the elastic force of the arc-shaped ring 21 to the V-fold locking part 22 and the end locking part 23, ensuring that the pressure generating part 6 is balanced by the force. The initial vertical distance of the ring elastic bearing mechanism 1 is smaller than the vertical locking distance of the pressure generating part 6. After the ring elastic bearing mechanism 1 is pulled open to install the pressure generating part 6, the ring elastic bearing mechanism 1 uses its own rebound pressure to firmly press the V-fold locking part 22 and the end locking part 23 of the pressure generating part 6 into the assembly strip hole 18 and the assembly hole 19, making it difficult to fall off.

[0047] Of course, to better meet user needs, the structure of the pressure spring can also be modified as follows: Figure 6 and Figure 7 The structure shown is as follows: Figure 6 The structure can increase the distance between the two symmetrical V-fold card parts 22 and the distance between the two end card parts 23, making the grip pressure more balanced; Figure 7 The structure can reduce the width of the pressure spring, making the product more compact.

[0048] Furthermore, the integrated protective cover mechanism 5 is a flat, ring-shaped structure made of silicone. Both sides of the integrated protective cover mechanism 5 are provided with anti-slip textures 25 to enhance the grip feel and friction. The flexibility of the silicone material can prevent the metal frame from directly contacting the hand and causing bumps and injuries. The flat, ring-shaped structure can conform to the curvature of the hand, reducing hand fatigue during long-term training. The anti-slip textures 25 can increase the friction between the hand and the grip strengthener, preventing the grip strengthener from slipping even when the hands are sweaty, ensuring stability during training, avoiding training interruptions or hand abrasions caused by slipping, and improving safety and comfort.

[0049] Furthermore, the inner side of the integrated protective covering mechanism 5 is provided with edge-wrapping adhesive 26 for covering the upper fold anti-detachment edge 16 and the lower fold anti-detachment edge 15, and the inner side of the integrated protective covering mechanism 5 is provided with escape adhesive holes 27 corresponding to the upper mounting hole 28 and the lower mounting hole 12.

[0050] In this embodiment, the pressure generating element 6 can be installed in quantities of 1 to 5, and can be configured with springs of different wire diameters and pressures. For example, it includes two rated working pressures, namely 5kg and 15kg, with a maximum working pressure of 75kg. By increasing or decreasing the number of pressure springs, the total pressure of the hand gripper can be adjusted in steps within the range of 5kg-75kg to meet the training needs of different groups of people. For beginners, they can start with a low number of pressure springs and gradually increase the training intensity.

[0051] For example, installing a 5kg compression spring with a total pressure of 5kg is suitable for people with weak hand strength, such as children, the elderly, or users in the early stages of postoperative recovery.

[0052] The combined installation of one 5kg and one 15kg pressure spring results in a total pressure of 20kg. It is suitable for users with some hand training experience. During training, the hands need to work together to exert force, which can improve the coordination and endurance of the hand muscles.

[0053] With five 15kg pressure springs installed, the total pressure is 75kg. It is suitable for users with strong hand strength, such as fitness enthusiasts and athletes who need to improve their hand explosiveness. It can provide high-intensity stimulation to the finger flexors and palmar interphalangeal muscles. Through continuous gripping and rapid release, it can improve the explosiveness and reaction speed of hand muscles. It is suitable for use in conjunction with a special training program, such as 15-20 repetitions per set, for 3-4 sets.

[0054] Training use: First, the initial distance between the upper bearing plate 2 and the lower bearing plate 3 of the annular elastic bearing mechanism 1 is less than the upper and lower end snapping distance of the pressure generator 6. After the pressure generator 6 snaps onto the upper bearing plate 2 and the lower bearing plate 3 through the V-fold snapping part 22 and the end snapping part 23 respectively, the rigid spring sheet 4 of the annular elastic bearing mechanism 1 generates an inward pre-tightening force due to the spacing being opened, which stabilizes and limits the pressure generator 6. At this time, the pressure generator 6 is in a slightly compressed state and has initial elastic potential energy.

[0055] Next, the user grips both sides of the integrated protective covering mechanism 5 with their hands, applying a gripping force towards the center. The upper pressure plate 2 and the lower pressure plate 3 move closer to each other under the action of external force, causing the left and right rigid spring pieces 4 to deform inward synchronously. The upper pressure plate 2 and the lower pressure plate 3 squeeze the pressure generating element 6, causing the arc-shaped ring 21 to further contract and deform, storing elastic potential energy. During this process, because the upper pressure plate 2 and the lower pressure plate 3 are arranged in parallel, the rigid spring pieces 4 deform symmetrically, and the pressure generating element 6 is evenly distributed, the pressure distribution in each contact area of ​​the hand is balanced, achieving balanced force. Among them, when the pressure generating element 6 is compressed to a certain extent, the two symmetrical V-shaped locking parts 22 on the left and right will press against the lower pressure plate 3 at the top of the connection part, which can limit the maximum pressure of the pressure generating element 6 and protect the pressure generating element 6 from being damaged by overpressure.

[0056] Finally, the user releases their grip, and the arc-shaped ring 21 of the pressure generator 6 releases elastic potential energy, pushing the upper pressure plate 2 and the lower pressure plate 3 to separate outward. The rigid spring 4 also releases deformation potential energy, assisting the upper pressure plate 2 and the lower pressure plate 3 to return to their initial distance. Throughout the process, the silicone material of the integrated protective covering mechanism 5 can buffer the rebound impact force, preventing the hand from being impacted by the sudden rebound and ensuring user comfort.

[0057] In summary, the present invention provides a silicone-wrapped ring-shaped elastic frame pressure adjustable grip strengthener. By embedding a ring-shaped elastic bearing mechanism 1 in an integrated protective covering mechanism 5 and using a detachable pressure generating element 6 to support the ring-shaped elastic bearing mechanism 1, it is suitable for different grip strength training. The entire symmetrical and centrally located design ensures that the hand is evenly stressed. The pressure is easy to change and adjust. It is small, portable, and provides comfortable and durable hand training.

[0058] The technical principles of the present invention have been described above with reference to specific embodiments, which are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments; all technical solutions falling within the scope of the present invention's concept are within its protection scope.
