Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a thumb ring for archery. Background Technology

[0002] The popularity of archery in China is increasing year by year. In traditional archery without a platform, the thumb's draw and release technique has certain advantages over using three fingers, leading to a growing number of players favoring this style. Consequently, more and more clubs, competitions, and archery ranges are being established based on this technique. However, because the thumb bears a lot of force in this style, it is prone to injury. Therefore, a thumb ring is an essential piece of protective gear. Its working principle is to distribute the force of the string on the thumb, thereby reducing the maximum pressure on the thumb.

[0003] Thumb rings currently available on the market can be divided into several categories: First, pure leather thumb rings. These have significant drawbacks: they are easily deformed, have poor pressure distribution, and are prone to causing pain. Over time, they can lead to thumb bruising, deformation, and ligament damage. Second, pure hard thumb rings. These have stronger pressure distribution and a better feel when released, but they have several disadvantages: poor fit (since everyone's finger shape is slightly different, a perfect fit is comfortable, while a slight mismatch can cause pain); easy slippage causing pain (under the pressure of the bowstring, the ring will slowly move towards the thumb joint, compressing the joint and causing significant pain, which can also lead to thumb injury and deformation over time); and easy slippage causing the ring to fly off (if the inner diameter of the ring is too large when it moves towards the thumb joint under the pressure of the bowstring, it may fly off, causing unexpected release and unpredictable consequences, such as arrows flying out and injuring people or causing property damage). Third: Partially hardened leather thumb rings combine the advantages of both pure leather and pure hard leather thumb rings. They offer moderate pressure distribution, but are still relatively easy to deform, and long-term use may lead to permanent deformation, reducing their protective effect. Furthermore, their feel when released is not as good as pure hard leather thumb rings. Fourth: Thumb rings with a soft inner leather and a hard outer material. Currently, only adjustable sizes are available for this type of thumb ring on the market, including a hardened leather thumb ring disclosed in patent CN215217351U. This type only has a hard material covering the outer part of the thumb pad, offering less support than pure hard leather thumb rings and a lower pressure distribution ability, which can easily cause pain over time.

[0004] In addition, all of the above types of thumb rings have adjustable models, but for individual users, adjustability is not very necessary, because they generally will not use other people's thumb rings or lend their own thumb rings to others, and their thumb size generally does not change much. Therefore, it is entirely possible to sacrifice some adjustability to increase support and improve comfort. Summary of the Invention

[0005] To address the aforementioned issues, this invention proposes a thumb ring with a rigid outer ring and a soft inner ring, which maximizes the combination of the advantages of various hard and soft thumb rings by sacrificing some unnecessary adjustability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: It includes a protective assembly and a soft layer covering the contact surface between the protective assembly and the thumb. The protective assembly includes an annular portion and a protruding portion, with one end of the annular portion integrally connected to one end of the protruding portion. The ratio A of the curved surface area of ​​the soft layer in contact with the thumb to the curved surface area of ​​the protective assembly in contact with the thumb when the soft layer is not covered is 0.5-1.

[0007] In practice, the protective assembly, including the ring and protruding parts, can be considered a complete rigid thumb ring, providing strong pressure distribution and excellent release feel. The soft layer covering the contact surface between the protective assembly and the thumb provides a degree of adaptability; it can deform appropriately in areas where the thumb experiences greater force to accommodate different thumb shapes, further enhancing the overall pressure distribution capability and making the thumb feel more comfortable. Sufficient effect is achieved as long as the area covered by the soft layer is slightly larger than the area of ​​the thumb that experiences greater force (generally the joint). In this design, the area covered by the soft layer should account for more than 50% of the contact area between the thumb and the thumb ring.

[0008] As a further embodiment of this invention, the soft layer extends out from the side of its edge away from the protrusion, surrounding and connecting to the outside of the annular portion.

[0009] In practice, the soft layer that extends and wraps around the outer side of the ring-shaped part serves to fix the relative position of the soft layer and the protective group, making it less likely for the soft layer and the protective group to slip relative to each other. This is especially important for maintaining a comfortable feel, because once it slips, it means that the ring is moving towards the thumb joint under the pressure of the bowstring, which will squeeze the joint and cause greater pain. Over time, this can lead to thumb injury and deformation.

[0010] As a further embodiment of this utility model, it also includes a rope and two limiting groups, and the annular part is provided with four holes. When the rope passes through the four holes, it presses the part of the soft layer extending outward to the outside of the annular part. The two ends of the rope pass through the first limiting group and are movably connected to it, and then pass through the second limiting group and are fixedly connected to it. The fixed position can be adjusted.

[0011] In practice, a seam will inevitably form where the soft layer extends and connects. The rope pressing down on the extended part of the soft layer can be placed precisely on this seam, further securing the soft layer and making it difficult to slip. Furthermore, by concealing the seam, the appearance is cleaner and more aesthetically pleasing. The closed area formed by the two limiting groups and the rope can encircle the wrist, preventing the ring from flying off. When not in use, the ring can be secured, also preventing loss to some extent. The rope is fixedly connected to the second limiting group, and its position can be adjusted to accommodate different hand sizes, ensuring a comfortable grip.

[0012] As a further embodiment of this invention, the soft layer is made of a non-slip and wear-resistant material.

[0013] In practical applications, materials with higher friction are better able to prevent the thumb ring from sliding against the thumb under the pressure of the bowstring, thus preventing pain caused by compression of the thumb joint.

[0014] As a further embodiment of this utility model, the anti-slip and wear-resistant material is top-grain cowhide or suede.

[0015] In practical applications, top-grain cowhide and suede offer good abrasion resistance, high friction, and are soft enough to effectively reduce thumb pain.

[0016] As a further embodiment of this invention, the material of the protective assembly is a hard material with a Shore hardness ≥60HD.

[0017] In practical operation, to effectively distribute the pressure of the bowstring, the protective assembly needs sufficient hardness to ensure that the thumb ring does not deform significantly under the pressure of the bowstring. Testing has shown that a Shore hardness of ≥60HD for the protective assembly meets the requirements.

[0018] As a further embodiment of this utility model, the rope is made of cowhide.

[0019] In practical applications, cowhide rope provides sufficient strength and does not fray at the end like ordinary braided rope, making it convenient to use and giving the overall appearance a cleaner look.

[0020] As a further embodiment of this utility model, the ratio A of the curved surface area of ​​the soft layer in contact with the thumb and the curved surface area of ​​the protective group in contact with the thumb when the soft layer is not covered is 0.7-1.

[0021] In practical work, the coverage area of ​​the soft layer can be appropriately increased to make it more comfortable to hold.

[0022] As a further embodiment of this utility model, the ratio A of the curved surface area of ​​the soft layer in contact with the thumb and the curved surface area of ​​the protective group in contact with the thumb when the soft layer is not covered is 0.95-1.

[0023] When working with the ring, you can maximize the coverage area of ​​the soft layer so that the area where the thumb contacts the ring is covered with the soft layer, making it more comfortable to hold. Attached Figure Description

The protective group is sleeved on the user's thumb, and the soft layer is disposed on the side of the protective group that contacts the thumb, in order to improve the comfort when wearing it.

[0025] Figure 4 This is a schematic diagram of an improved structure based on Embodiment 1 for Embodiment 2 of the present invention. Based on Embodiment 1, the soft layer extends outward at its edge position. The extended portion is used to restrict the slippage of the soft layer during wearing, thereby improving wearing stability.

[0028] Figure 8 and Figure 9 This is a schematic diagram of an improved structure based on Embodiment 1 in Embodiment 4 of the present invention. Compared with Embodiment 1, the coverage area of ​​the soft layer is increased, allowing the soft layer to cover more of the contact area between the ring and the thumb, thereby further improving the comfort when wearing it.

[0029] Figure 10 and Figure 11 This is a schematic diagram of an improved structure based on Embodiment 1 in Embodiment 5 of the present invention. Compared with Embodiment 4, the coverage area of ​​the soft layer is further expanded, and the soft layer almost covers the contact surface between the ring and the thumb, so as to maximize the comfort when wearing it.

[0030] Figures 12 to 14This is a schematic diagram illustrating the use of a preferred embodiment of the present invention, which combines the features of Embodiments 3 and 5.

[0031] Among them, 1 is the protection group; 2 is the soft layer; 3 is the rope; 4 is the first limiting group; 5 is the second limiting group; 6 is the hand; 101 is the ring-shaped part; 102 is the protruding part; 103 is the first hole; 104 is the second hole; 105 is the third hole; and 106 is the fourth hole. Detailed Implementation

[0032] like Figure 1 and 2 As shown, a thumb ring for archery includes a protective assembly 1 and a soft layer 2 covering the contact surface between the protective assembly 1 and the thumb. Figure 3 As shown, the protective assembly 1 includes an annular portion 101 and a protruding portion 102, with one end of the annular portion 101 integrally connected to one end of the protruding portion 102. The ratio A of the curved surface area of ​​the soft layer 2 in contact with the thumb to the curved surface area of ​​the protective assembly 1 in contact with the thumb when the soft layer 2 is not covered is 0.5-1.

[0033] In practical operation, the protective assembly 1, including the annular portion 101 and the protruding portion 102, can be considered as a complete rigid thumb ring, providing strong pressure dispersion and excellent release feel. The soft layer 2 covering the contact surface between the protective assembly 1 and the thumb provides a certain degree of adaptability. It can deform appropriately in areas where the thumb experiences greater force to accommodate different thumb shapes, further enhancing the overall pressure dispersion capability and making the thumb feel more comfortable. The area covered by the soft layer 2 only needs to be slightly larger than the area of ​​the thumb that experiences greater force (generally the joint) to produce sufficient effect. In this design, it is defined that the area covered by the soft layer 2 accounts for more than 50% of the contact area between the thumb and the thumb ring.

[0034] As a further embodiment of this utility model, such as Figure 4 As shown, the soft layer 2 extends out from the side of its edge away from the protrusion 102, surrounding and connecting to the outside of the annular portion 101.

[0035] In practical operation, the soft layer that extends and surrounds the outer side of the ring-shaped portion 101 serves to fix the relative position of the soft layer 2 and the protective group 1, making it less likely for the soft layer 2 and the protective group 1 to slip relative to each other. This is especially important for maintaining a comfortable feel, because once it slips, it means that the ring is moving towards the thumb joint under the pressure of the bowstring, which will cause great pain and, over time, lead to thumb injury and deformation.

[0036] As a further embodiment of this utility model, such as Figure 5 As shown, it also includes a rope 3, a first limiting group 4, and a second limiting group 5, and as... Figure 6 and Figure 7 As shown, the annular portion 101 has four holes. The rope 3 passes through these four holes simultaneously... Figure 5 As shown, the extended portion of the soft layer 2 is pressed tightly against the outside of the annular portion 101. The two ends of the rope 3 pass through the first limiting group 4 and are movably connected to it, and then pass through the second limiting group 5 and are fixedly connected to it. The fixed position can be adjusted.

[0037] In actual operation, a seam will inevitably form where the soft layer 2 extends and connects. The rope 3, which presses down on the extended part of the soft layer 2, can press precisely on the seam. On the one hand, this further secures the soft layer 2, making it difficult to slip; on the other hand, by concealing the seam of the soft layer 2, the appearance is more concise and aesthetically pleasing. The closed area formed by the two limiting groups and the rope 3 can wrap around the wrist, preventing the ring from flying off. Moreover, when the ring is not in use, it can be tied in a certain place, which can also prevent loss to some extent. The rope 3 is fixedly connected to the second limiting group 5, and its fixed position can be adjusted to accommodate different hand sizes, so that the ring is in a more comfortable position for use after proper adjustment.

[0038] As a further embodiment of this utility model, the soft layer 2 is made of a non-slip and wear-resistant material.

[0039] In practical applications, materials with higher friction are better able to prevent the thumb ring from sliding against the thumb under the pressure of the bowstring, thus preventing pain caused by compression of the thumb joint.

[0040] As a further embodiment of this utility model, the anti-slip and wear-resistant material is top-grain cowhide or suede.

[0041] In practical applications, top-grain cowhide and suede offer good abrasion resistance, high friction, and are soft enough to effectively reduce thumb pain.

[0042] As a further embodiment of this utility model, the material of the protection group 1 is a hard material with a Shore hardness ≥60HD.

[0043] In practical operation, to effectively distribute the pressure of the bowstring, the protective assembly 1 needs to have sufficient hardness so that the thumb ring does not deform significantly under the pressure of the bowstring. Testing showed that a Shore hardness of ≥60HD for the protective assembly 1 meets the requirements.

[0044] As a further embodiment of this utility model, the material of rope 3 is cowhide rope.

[0045] In practical applications, cowhide rope provides sufficient strength and does not fray at the end like ordinary braided rope, making it convenient to use and giving the overall appearance a cleaner look.

[0046] As a further embodiment of this utility model, such as Figure 8 and Figure 9 As shown, the ratio A of the curved surface area of ​​the soft layer 2 in contact with the thumb and the curved surface area of ​​the protective group 1 in contact with the thumb when the soft layer 2 is not covered is 0.7-1.

[0047] In practical work, the coverage area of ​​the soft layer 2 can be appropriately increased to make the feel more comfortable.

[0048] As a further embodiment of this utility model, such as Figure 10 and Figure 11 As shown, the ratio A of the curved surface area of ​​the soft layer 2 in contact with the thumb and the curved surface area of ​​the protective group 1 in contact with the thumb when the soft layer 2 is not covered is 0.95-1.

[0049] In practice, the coverage area of ​​the soft layer 2 can be increased as much as possible so that the area where the thumb contacts the ring is covered by the soft layer 2, making the feel more comfortable.

[0050] like Figure 12 , Figure 13 and Figure 14 As shown, this embodiment of the present invention includes a protective group 1, a soft layer 2, a rope 3, a first limiting group 4, and a second limiting group 5. The soft layer 2 is disposed at the position where the protective group 1 contacts the thumb and basically covers the contact area between the thumb and the ring to obtain a more comfortable feel. One end of the rope 3 is connected to the protective group 1, and the other end is used to connect to the user's wrist. The first limiting group 4 and the second limiting group 5 are disposed on the rope 3 to limit the position or length of the rope, so that this embodiment has the functions of preventing the ring from flying off and preventing loss.
