Combined grip strengthener

Abstract

This utility model discloses a combined grip strengthener, which consists of at least two nestable elastic annular components. The first grip strengthener has a first annular portion with a radial thickness that varies in segments or gradually along the circumference, and the second grip strengthener has a second annular portion with the same variation. The two grip strengtheners are rotatably fitted together by a concave-convex connection structure formed by the first and second annular grooves on the outer circumferential surface and the first side, the middle groove, and the second side on the inner circumferential surface. During rotation, the different thicknesses are superimposed, causing the overall elastic modulus to change continuously, thereby providing multiple grip strength levels on the same device. The outer and / or inner surfaces of the annular portions are provided with raised, grooved, or textured anti-slip structures. The grip strengthener is molded in one piece from silicone, rubber, or thermoplastic elastomer, making it soft and durable.

Description

Technical Field

[0001] This utility model relates to a grip strengthener, and more particularly to a combined grip strengthener, which is formed by two ring grip strengtheners nested together. Background Technology

[0002] A hand grip strengthener is a small, lightweight, and portable fitness device designed to fit the shape of the human hand. It can help users strengthen their hand muscles, relieve fatigue, strengthen muscles, and improve blood circulation through various exercise methods such as single-handed, double-handed, overhand, underhand, and double-clamping. Long-term use can also help prevent diseases such as rheumatoid arthritis. It is a commonly used tool for fitness exercise.

[0003] Two patent documents related to combined hand grippers have been disclosed in the prior art:

[0004] One is the "combined grip strength device" with patent number CN203803054U. This grip strength device includes multiple outer grip rings and one inner grip ring, all made of silicone. The inner circumference of the outer grip ring has an annular groove with a cross-section in the shape of a C. Multiple outer grip rings and inner grip rings can be nested and combined with each other. The outer surface of the largest outer grip ring has protruding silicone particles, which are designed to adjust grip strength.

[0005] The second is the "Combined Adjustable Grip Force Device" with patent number CN212038836U, which includes an inner grip ring and an outer grip ring, both of which are solid silicone structures. The first inner side of the outer grip ring forms an annular groove, and the inner grip ring is assembled in the groove. The inner grip ring is provided with a second reinforcing rib and a pattern to enhance the friction with the outer grip ring and reduce the possibility of it falling off.

[0006] However, existing combination grip strengtheners still have shortcomings in practical use. Although the aforementioned patents attempt to adjust grip strength through a combination structure, due to limitations such as structural design, the grip strength value selection after combination is relatively limited, failing to fully meet the personalized needs of people with different strength levels (such as beginners, fitness enthusiasts, and professional athletes). Furthermore, as users progress in their training, their hand strength gradually increases, and existing combination grip strengtheners struggle to adapt to this change in strength, failing to provide users with a continuously progressive training intensity, thus affecting training effectiveness.

[0007] The technical problem to be solved by this utility model is to provide a combined grip strength device that can provide multiple grip strength values.

[0009] The first gripper has a first annular portion, the radial thickness of which varies along its circumference; the second gripper has a second annular portion, the radial thickness of which also varies along its circumference.

[0010] When the first gripper is fitted over the outside of the second gripper, various gripper structures with different grip strength values ​​can be formed by adjusting the nesting combination of the two grippers at different circumferential positions.

[0013] A further technical solution of this utility model is as follows: the outer peripheral surface of the second gripper is provided with a parallel first annular groove and a second annular groove to form a first side protrusion ring, a middle protrusion ring and a second side protrusion ring; the inner peripheral surface of the first gripper is provided with a first side edge, a middle groove and a second side edge; after the first gripper and the second gripper are fitted together, the middle protrusion ring is embedded in the middle groove, the first side edge is embedded in the first annular groove and the second side edge is embedded in the second annular groove.

[0014] A further technical solution of this utility model is that the outer surface and / or inner surface of the annular portion are provided with an anti-slip structure.

[0015] A further technical solution of this utility model is that the anti-slip structure is one or more combinations of protrusions, grooves, or textures.

[0016] A further technical solution of this utility model is as follows: the first grip strengthener and the second grip strengthener are made of elastic material, which is one of silicone, rubber or thermoplastic elastomer.

[0017] Another technical solution adopted by this utility model to solve the above-mentioned technical problems is: a combined grip strengthener, characterized in that the grip strengthener is composed of two grip strengthener components that can be nested with each other, specifically including a first grip strengthener and a second grip strengthener;

[0018] The radial thickness of the first annular portion of the first gripper varies along its circumference, and the radial thickness of the second annular portion of the second gripper also varies along its circumference. A matching connection structure is provided between the inner circumferential surface of the first gripper and the outer circumferential surface of the second gripper, so that the first gripper can be fitted onto the outside of the second gripper.

[0019] After the first gripper is fitted onto the outside of the second gripper via a connecting structure, the gripper has multiple force application points with different gripping force values;

[0020] By adjusting the nesting combination of the first and second grippers at different circumferential positions, a variety of gripper structures with different grip strength specifications can be formed.

[0021] A further technical solution of this utility model is: the connection structure includes:

[0022] The outer peripheral surface of the second gripper is provided with a parallel first annular groove and a second annular groove; forming a first side protrusion ring, a middle protrusion ring and a second side protrusion ring; the inner peripheral surface of the first gripper is provided with a first side edge, a middle groove and a second side edge.

[0023] After the first gripper and the second gripper are fitted together, the middle convex ring is embedded in the middle groove, the first side is embedded in the first annular groove, and the second side is embedded in the second annular groove.

[0024] A further technical solution of this utility model is: the outer surface and / or inner surface of the annular portion are provided with an anti-slip structure; the anti-slip structure is one or more combinations of protrusions, grooves or textures;

[0025] The first and second grip strengtheners are made of elastic material; the elastic material is one of silicone, rubber or thermoplastic elastomer.

[0026] A further technical solution of this utility model is: the radial thickness of the first annular portion varies in segments along the clockwise or counterclockwise direction; the radial thickness of the second annular portion varies in segments along the clockwise or counterclockwise direction.

[0027] Alternatively, the radial thickness of the first annular portion may vary gradually in a clockwise or counterclockwise direction, and the radial thickness of the second annular portion may vary gradually in a clockwise or counterclockwise direction.

[0028] Compared with existing technologies, the advantages of this invention are: when the first grip strengthener is fitted over the second grip strengthener, the entire combined grip strengthener can provide a variety of different grip strength combinations. This technology enables the entire combined grip strengthener to achieve multiple different grip strength combinations, significantly improving the flexibility and diversity of training, meeting the training needs of different users at different stages, and thus achieving better training results.

[0029] In addition, the outer and / or inner surfaces of the ring are provided with an anti-slip structure, which can be one or more combinations of protrusions, grooves, or textures. This technology allows the spacing of the protrusions to match the tactile sensation of the fingertips, improving the accuracy of skin deformation perception, providing rhythmic feedback to the user, and extending the effective training time. At the same time, this structure improves grip stability, avoids the slippage of traditional smooth rubber rings, and enhances training safety. Attached Figure Description

[0040] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0041] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0042] like Figures 1 to 4 The diagram shows the structure and usage of a combined grip strengthener 100. The combined grip strengthener 100 comprises at least two nestable grip strengthener components, specifically including a first grip strengthener 10 and a second grip strengthener 20. The first grip strengthener 10 has a first annular portion 11, the radial thickness of which varies along its circumference. The second grip strengthener 20 has a second annular portion 21, the radial thickness of which also varies along its circumference.

[0043] The radial thickness of the first annular portion 11 of the first gripper 10 and the second annular portion 21 of the second gripper 20 varies along their circumference (it can be segmented or gradually varied, as will be described below). When the first gripper 10 is fitted over the outside of the second gripper 20, various gripper structures with different grip strength specifications can be formed by adjusting the nesting combination of the two grippers at different circumferential positions.

[0044] The aforementioned technology allows users to choose different grip strength values ​​based on their strength level and training needs. For example, beginners can choose a lower grip strength value, while experienced trainees can choose a higher grip strength value. As the user progresses in their training, their hand strength gradually increases, and this design adapts to this change in strength, providing users with a continuously progressive training intensity.

[0045] like Figures 7 to 8The diagram shows the overall and side views of the first grip strengthener 10. After the first grip strengthener 10 is fitted onto the outside of the second grip strengthener 20 via a connecting structure r, it has multiple force application points with different grip strength values. When the first grip strengthener 10 is fitted onto the outside of the second grip strengthener 20, various grip strengthener structures with different grip strength specifications can be formed by adjusting the nesting combination of the two grip strengtheners at different circumferential positions. This technology allows users to switch grip strength levels simply by rotating the outer layer, improving the switching experience. Simultaneously, all force application points share the same annular material, without adding extra parts or thickness, meeting the training needs of users in different scenarios.

[0046] The radial thickness of the first annular portion 11 varies in segments along the clockwise or counterclockwise direction; the radial thickness of the second annular portion 21 also varies in segments along the clockwise or counterclockwise direction. For example, when three different grip strength values ​​are set for training, the required grip strength is α when pressing the grip strengthener at the first segment of the annular portion, β when pressing the grip strengthener at the second segment of the annular portion, and γ when pressing the grip strengthener at the third segment of the annular portion, where α > β > γ. At this time, the three different thicknesses correspond to three different grip strength values. Of course, four or five different thicknesses can also be set to correspond to four or five different grip strength values. In addition, each different thickness segment can be distributed from large to small, or it can be an irregularly and randomly distributed grip strength segment with different force values.

[0047] In another scenario, the radial thickness of the first annular portion 11 varies gradually in either a clockwise or counterclockwise direction, as does the radial thickness of the second annular portion 21. This technique allows the radial thickness of the annular portions to vary gradually, resulting in a gradual increase in the required grip strength. Users will have a wider range of grip strength training options, and the changes between grip strength values ​​will be more subtle, allowing for smaller increases in training intensity.

[0048] Based on the aforementioned technical means, when the first grip strengthener 10 is fitted outside the second grip strengthener 20, the entire combined grip strengthener can provide a variety of different grip strength value combinations. This technical means enables the entire combined grip strengthener to achieve multiple different grip strength value combinations, significantly improving the flexibility and diversity of training, meeting the training needs of different users at different stages, and thus achieving better training results.

[0049] like Figures 5 to 6The diagram shows the overall and side views of the second grip strengthener 20. Specifically, the connecting structure r has parallel first annular grooves 22 and 23 on its outer circumferential surface, forming a first side protrusion b1, a middle protrusion b2, and a second side protrusion b3. The inner circumferential surface of the first grip strengthener 10 has a first side edge 12, a middle groove 13, and a second side edge 14. After the first grip strengthener 10 and the second grip strengthener 20 are fitted together, the middle protrusion b2 is embedded in the middle groove 13, the first side edge 12 is embedded in the first annular groove 22, and the second side edge 14 is embedded in the second annular groove 23. This technology allows for precise alignment of the first grip strengthener 10 and the second grip strengthener 20, improving product stability. Simultaneously, users can switch between light and heavy or heavy and light intensity within seconds, improving training efficiency.

[0050] Preferably, an anti-slip structure f can be provided on the outer and / or inner surface of the annular portion of the first gripper 10 or the second gripper 20. The anti-slip structure f is one or more combinations of a protrusion f1, a groove f2, or a texture. This technique improves the user's grip stability, avoids the slippage of traditional smooth rubber rings, and enhances training safety.

[0051] like Figure 9 As shown, the outer surface of the annular portion of the second gripper 20 is provided with a protrusion f1, and a mounting hole f3 is provided at the corresponding position on the annular portion of the first gripper 10 for the protrusion f1 to pass through. The protrusion f1 passes through the mounting hole f3, forming an anti-slip protrusion for the user's hand to grip. This technical means, by providing a groove f2 on the annular portion of the first gripper 10, makes the structural position of the user's hand to grip clearer. At the same time, the groove f2 and the mounting hole f3 are distributed alternately, which allows the user to flexibly choose the groove f2 or the protrusion f1 for gripping.

[0052] Furthermore, it should be noted that the groove f2 mentioned in this embodiment can be either a through-hole structure or a recess only within the outer surface of the annular portion. The first grip strengthener 10 and the second grip strengthener 20 are made of elastic material, which is one of silicone, rubber, or thermoplastic elastomers. This technology enhances skin sensitivity through deformation, provides rhythmic feedback to the user, and extends the effective training time. Simultaneously, the use of silicone, rubber, or thermoplastic elastomers as the material results in lightweight, washable, drop-resistant, and rust-free properties, improving product durability.
