Description

A braided wristband and its braiding method Technical Field

[0001] This invention relates to an accessory for portable electronic devices, and more particularly to a wrist strap woven from a single paracord and having a linkage adjustment function, and a method for weaving the same. Background Technology

[0002] In the fields of photography and other portable electronic devices, wrist straps serve as safety accessories to assist in holding valuable equipment (such as cameras and high-end mobile phones). Their primary task is to provide a reliable and stable load-bearing connection to prevent accidental slippage and damage. They not only need to help users hold the device stably but also maintain extremely high reliability during frequent adjustments and daily use.

[0003] However, existing wrist straps designed specifically for such scenarios still have some shortcomings in design and function. For example, some wrist straps use a fixed length design or rely on external parts such as metal buckles or plastic pins for length adjustment. This type of design not only increases weight, cost, and the possibility of failure, but also makes adjustment less convenient and smooth, and external parts pose a risk of scratching the surface of the equipment. In addition, although there are wrist straps that use braiding technology, to achieve loop adjustment in the braided structure, additional buckles or metal or plastic accessories are often required. More importantly, for applications that need to withstand the weight of the equipment and dynamic impacts, existing solutions often struggle to balance structural simplicity, ease of adjustment, and load-bearing reliability. They are either structurally complex, inconvenient to adjust, or their core braided structure and material selection are not optimized for the specific needs of bearing the weight and providing safety protection for electronic devices weighing hundreds of grams to several kilograms.

[0004] Therefore, there is an urgent need in the market for a wrist strap solution that is designed to securely hold valuable portable electronic devices, is simple in structure, easy to adjust, requires no additional accessories, and maintains extremely high load-bearing reliability throughout use. Summary of the Invention

[0005] To address the shortcomings of existing wrist straps designed for expensive portable electronic devices, which struggle to balance structure, reliability, and convenience, this invention proposes a braided wrist strap and its braiding method. Its core innovation lies in providing a one-piece braided structure that, without requiring any metal or plastic components, not only allows for convenient, interconnected adjustments to suit different users but also ensures extremely high reliability and durability during the daily load-bearing and dynamic use of expensive electronic devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A braided wrist strap is provided to assist a user in firmly gripping a portable electronic device. The wrist strap is woven from a single paracord and its overall structure includes a device loop 1, a wrist loop 2, and a knotted portion 3 located between the two. The device loop 1 is used to secure the portable electronic device; the wrist loop 2 is used to wrap around and secure the user's wrist; the two ends of the knotted portion 3 are respectively connected to the device loop 1 and the wrist loop 2.

[0008] The device's opening 1 is connected to the knotted portion 3 via two rope segments 1a and 1b, and the wrist opening 2 is connected to the knotted portion 3 via two rope segments 2c and 2d. Crucially, one of the rope segments 1a and 1b of the device's opening 1 and one of the rope segments 2c and 2d of the wrist opening 2 are linked in length adjustment; that is, when one rope segment is lengthened, the other rope segment shortens accordingly, and vice versa. This design allows the wrist strap to adapt to different users' wrist sizes without the need for additional metal or plastic accessories.

[0009] Furthermore, the two ends of the knotted portion 3 are respectively connected to the device ring 1 and the wrist ring 2. The device ring 1 is connected to the knotted portion 3 via two rope segments 1a and 1b, and the wrist ring 2 is connected to the knotted portion 3 via two rope segments 2c and 2d. One of the two rope segments 1a and 1b of the device ring 1 and one of the two rope segments 2c and 2d of the wrist ring 2 are linked in length adjustment; that is, when the length of one rope segment is lengthened, the length of the other rope segment will shorten accordingly, and vice versa. Specifically, this includes:

[0010] The device opening 1 is formed by the first rope segment 1a and the second rope segment 1b extending from the knot portion 3.

[0011] The wrist ring 2 is formed by the third rope segment 2c and the fourth rope segment 2d extending from the knot portion 3.

[0012] The knot portion 3 is a core-filled knot structure, consisting of a braided body and two inner rope segments. The braided body is formed by two braiding rope segments winding around the two inner rope segments. The two inner rope segments include an adjusting rope segment and a fixing rope segment. The adjusting rope segment is formed by the continuous and direct connection between the end of the second rope segment 1b and the end of the fourth rope segment 2d; the fixing rope segment is formed by the extension of either the first rope segment 1a or the third rope segment 2c, located inside the knot portion 3. The two braiding rope segments are formed by the extensions of the first rope segment 1a and the third rope segment 2c joined together, and together winding around the adjusting rope segment and the fixing rope segment to form the core-filled knot.

[0013] By pulling the knotted part 3, the braided body and the adjusting rope segment can slide relative to each other, thereby changing the effective length of the second rope segment 1b of the device ring 1 and the fourth rope segment 2d of the wrist ring 2 in a coordinated manner, so as to realize the coordinated adjustment of the size of the device ring 1 and the wrist ring 2.

[0014] As an optimized implementation, the second rope segment 1b of the device's opening 1 and the fourth rope segment 2d of the wrist opening 2 are located on the same side of the knot portion 3, that is, the adjusting rope segment and the fixing rope segment are parallel and side-by-side inside the knot portion 3. This structure optimizes the operating feel and logic.

[0015] This invention also integrates intuitive guidance and a mechanism to prevent misoperation. Specifically, a label 4 can be provided on the first rope segment 1a of the device opening 1, near the knot portion 3. This label 4 is used to indicate that the adjusting rope segment is located on the side of the device opening 1 where the label 4 is not provided.

[0016] In terms of material selection, the paracord is preferably a high-strength paracord with a wear-resistant outer sheath 5 and at least two separable, independently load-bearing inner cores 6. More preferably, the high-strength paracord comprises seven or nine separable, independently load-bearing inner cores 6, and the paracord diameter is 4 mm or more.

[0017] To enhance compatibility with different device interfaces, at least one strand can be partially removed from the seven or nine separable independent load-bearing inner core 6 before weaving, thereby reducing the diameter of the wrist rope after weaving to accommodate electronic device interfaces of different sizes.

[0018] The core-filled knot can be of various forms, such as a core-filled snake knot, a core-filled diamond knot, a core-filled square knot, a core-filled lock knot, a core-filled dragon scale knot, or a core-filled four-strand braid. To ensure strength and feel, the number of core-filled knots is preferably 6 to 20, and the total length of the wrist strap is preferably 20 to 30 centimeters.

[0019] Regarding the rope finishing, both ends of the single paracord can be located at the connection between the device loop 1 and the knot portion 3, or both at the connection between the wrist loop 2 and the knot portion 3. To further enhance stability and aesthetics, the two ends of the single paracord can be extended from the aforementioned connection points and woven into decorative ends 3e and 3f. The decorative ends 3e and 3f can be selected from common knot forms in the art, such as the phoenix tail knot, dragonfly knot, pumpkin knot, double overhand knot, barrel knot, or lark's head knot.

[0020] The wrist strap described in this invention is particularly suitable for portable electronic devices such as cameras or mobile phones.

[0021] The present invention also provides a weaving method for weaving the wristband as described above, characterized by comprising the following steps:

[0022] S1. Rope segment preparation: Divide the body of a single paracord into the first rope segment 1a, the second rope segment 1b, the third rope segment 2c, the fourth rope segment 2d, and two weaving rope segments.

[0023] S2. Forming a ring: The first rope segment 1a and the second rope segment 1b are enclosed to form a device ring 1, and the third rope segment 2c and the fourth rope segment 2d are enclosed to form a wrist ring 2.

[0024] S3. Setting internal rope segments: Determine that the continuous part of the second rope segment 1b and the fourth rope segment 2d is used as the adjustment rope segment, and determine that one of the first rope segment 1a and the third rope segment 2c is used as the fixed rope segment. The adjustment rope segment and the fixed rope segment together serve as two internal rope segments.

[0025] S4. Weaving a core-filled knot: The two weaving rope segments are wrapped around and covered by the adjusting rope segment and the fixed rope segment to form a knot part 3. The knot part 3 is a core-filled knot structure, and a relative sliding relationship is established between the woven body formed by the weaving rope segments and the adjusting rope segment.

[0026] The braided wristband of the present invention has the following beneficial effects:

[0027] 1. Achieves stepless linkage adjustment through a pure woven structure, with a simple design and no additional accessories. Through a specific weaving method, the sizes of the device's inner ring 1 and the wrist ring 2 can be adjusted in tandem, eliminating the need for external accessories such as metal buckles and plastic pins found in traditional solutions. This not only simplifies the structure and reduces cost and weight but also avoids the risk of external accessories scratching the device, allowing the product to adapt to different users' wrist sizes and significantly improving its applicability and ease of use.

[0028] 2. A highly reliable integrated load-bearing solution is provided. By selecting high-strength paracord (such as a seven- or nine-core structure with a diameter of 4 mm or more) and optimizing the number of knots (6-20), a highly integrated and simple structure is achieved while ensuring sufficient support for portable electronic devices (such as cameras and mobile phones). The rope itself combines a wear-resistant outer sheath 5 and an independent load-bearing inner core 6, ensuring the product's durability under daily use and dynamic impacts.

[0029] 3. The operation logic was optimized through a parallel internal structure. The adjustment rope segments (second rope segment 1b and fourth rope segment 2d), which form the core of the linkage, are positioned on the same side of the knot, creating a parallel internal structure. This design optimizes the force transmission path during adjustment, resulting in consistent feel and clear direction for the adjustment of both loops. This significantly reduces user confusion regarding the object being adjusted, improving accuracy and efficiency.

[0030] 4. Integrates intuitive anti-misoperation and physical limiting mechanisms. Based on the above parallel structure, a label 4 is set on the fixed rope segment side (such as the first rope segment 1a) at the device's opening, providing users with clear visual or tactile indications to accurately identify the adjustable side. This design effectively avoids invalid pulling attempts and, combined with the physical limiting function of label 4, prevents the adjusting rope segment from being pulled out excessively, improving product usability and effectively preventing structural failures caused by misoperation.

[0031] 5. Achieving a unified technology for standardized design and customized adaptation. By performing a core-pulling process on the paracord before weaving, the diameter and flexibility of the cord can be flexibly adjusted without altering the core weaving structure and appearance, allowing it to easily adapt to device interfaces of different sizes. This technology enables the use of standardized weaving processes to meet the customized adaptation needs of portable electronic products with varying device interface sizes.

[0032] 6. While ensuring core functionality and safety, the product achieves a unity of aesthetics, structure, and practicality. The use of a variety of colorful paracord materials allows for personalized customization to meet user needs. Furthermore, the technique of weaving decorative ends such as phoenix tail knots (3e, 3f) not only gives the product a unified appearance but also enhances structural stability, ease of maintenance, and anti-slip safety during temporary grips by wrapping the knotted points and providing operational leeway. Thus, while satisfying aesthetic requirements, the product's durability and user experience are comprehensively improved.

[0033] 7. The reasonable design of the total length of the wrist strap (20-30 cm) further optimizes the wearing comfort and overall coordination. Attached Figure Description

[0067] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings:

[0068] I. Overall Structure Description

[0069] As shown in Figure 1(A), the present invention provides a braided wrist strap to help users hold portable electronic devices securely. Its main structure includes a device loop 1, a wrist loop 2, and a knotted part 3 located between the two.

[0070] Device ring 1: This part is designed to be fixed to portable electronic devices, such as cameras or mobile phones, to ensure the convenience and safety of users when taking pictures or carrying portable electronic devices.

[0071] Wristband 2: This part wraps around and secures to the user's wrist, ensuring the stability of the wristband and preventing it from slipping or being lost during use.

[0072] Knot section 3: The two ends of the knot section 3 are respectively connected to the device ring 1 and the wrist ring 2; the device ring 1 is connected to the knot section 3 through two rope segments 1a and 1b, and the wrist ring 2 is connected to the knot section 3 through two rope segments 2c and 2d. The knot section 3 adopts a known weaving method such as the core-wrapped snake knot, and the number of knots varies from 6 to 20. This design not only ensures the strength and durability of the wrist strap, but also realizes the function of adjusting the size of the ring by pulling, meeting the needs of different users' wrist sizes.

[0073] The wrist strap is woven from a single paracord. As shown in Figure 5(J), the paracord is a high-strength paracord with an abrasion-resistant outer sheath 5 and at least two separable, independently load-bearing inner cores 6. The diameter of the paracord is 4 mm or more, preferably with a seven-core or nine-core structure, that is, including seven or nine separable, independently load-bearing inner cores to enhance its strength and durability. The total length of the wrist strap ranges from 20 to 30 cm, preferably 22 cm, 24 cm, or 26 cm.

[0074] Specifically, the device opening 1 is formed by the first rope segment 1a and the second rope segment 1b extending from the knot portion 3.

[0075] The wrist ring 2 is formed by the third rope segment 2c and the fourth rope segment 2d extending from the knot portion 3;

[0076] The knot portion 3 is a core-wrapped knot structure, consisting of a braided body and two inner rope segments (as shown in (E3) and (F3) in Figure 3). The braided body is formed by two braiding rope segments winding around the two inner rope segments (as shown in (E1)-(E3) and (F1)-(F3) in Figure 3), wherein:

[0077] The two internal rope segments include an adjusting rope segment and a fixing rope segment;

[0078] The adjusting rope segment is formed by the continuous and direct connection between the end of the second rope segment 1b and the end of the fourth rope segment 2d;

[0079] The fixed rope segment is formed by an extension of either the first rope segment 1a or the third rope segment 2c located inside the knot portion 3.

[0080] The two braiding rope segments are formed by the extension of the first rope segment 1a and the extension of the third rope segment 2c, which are joined together and wrapped around the adjusting rope segment and the fixing rope segment to form the core-filled knot.

[0081] In this process, by pulling the knotted part 3, the braided body and the adjusting rope segment slide relative to each other, thereby changing the effective length of the second rope segment 1b of the device ring 1 and the fourth rope segment 2d of the wrist ring 2 in a coordinated manner, so as to realize the linkage adjustment of the size of the device ring 1 and the wrist ring 2, as shown in (C) and (D) in Figure 2.

[0082] When the fixed rope segment is formed by the extension of the third rope segment 2c located inside the knot portion 3 (as shown in (E1)-(E3) and (F1)-(F3) in Figure 3), the two braiding rope segments begin to braid together at the connection between the device loop 1 and the knot portion 3, ending at the connection between the wrist loop 2 and the knot portion 3. At this time, both ends of the single paracord are located at the connection between the wrist loop 2 and the knot portion 3, as shown in (A) of Figure 1. When the fixed rope segment is formed by the extension of the first rope segment 1a located inside the knot portion 3, the two braiding rope segments begin to braid together at the connection between the wrist loop 2 and the knot portion 3, ending at the connection between the device loop 1 and the knot portion 3. At this time, both ends of the single paracord are located at the connection between the device loop 1 and the knot portion 3, as shown in (B) of Figure 1.

[0083] II. Length Adjustment and Wearing Method

[0084] As shown in Figures 2(C) and (D), the shape of the wrist strap when attached to the camera and its length adjustment mechanism are further illustrated. One of the two rope segments 1a and 1b of the device loop 1 is linked to one of the two rope segments 2c and 2d of the wrist loop 2 during length adjustment. When one rope segment (e.g., the third rope segment 2c or the fourth rope segment 2d) is lengthened, the length of the other rope segment (e.g., the second rope segment 1b) will shorten accordingly, and vice versa. Whether the third rope segment 2c is linked to the second rope segment 1b, or the fourth rope segment 2d is linked to the second rope segment 1b, depends on the placement of the two inner rope segments encased within the knot during the weaving process of the knot portion 3, such as a core-wrapped snake knot. This embodiment does not impose any limitations on this. This design allows the wrist strap to adapt to different users' wrist sizes without requiring additional metal or plastic fittings.

[0085] It should be noted that although the core-spun snake knot has the characteristic of being pullable, in the weaving of hanging ropes, the purpose of choosing the core-spun snake knot instead of the ordinary snake knot is usually only for the roundness of the knot, not for the ability to adjust the length. Therefore, even if the core-spun snake knot is used in the prior art, when adjusting the size of the loop, it is usually necessary to set additional rope buckles or metal or plastic accessories, rather than adjusting the size of the two loops in conjunction as in the solution of this invention. This is the core innovation of this invention. In addition, as an alternative implementation, in addition to the core-spun snake knot, the knot part 3 can also use the core-spun diamond knot, core-spun flat knot, core-spun lock knot, core-spun dragon scale knot, core-spun four-strand braid, etc., as long as it can adjust the size of the two loops in conjunction. This embodiment does not limit this.

[0086] When attaching the wrist strap to the camera, the user can first adjust the wrist loop 2 to a suitable length, making it easy to wear on the wrist without easily falling off, and then fix the device loop 1. When wearing the wrist strap, the user can adjust the wrist loop 2 to a larger size according to actual needs, easily put it on the wrist, and then return it to a suitable shape.

[0087] The aforementioned linkage adjustment function is achieved through the unique weaving structure inside the knot section 3. Specifically, inside the knot section 3, the rope segments constituting the device ring 1 and the wrist ring 2 are divided into sliding adjustment rope segments and fixed rope segments. By pulling the knot section 3, the braided body formed by the weaving rope segments can slide relative to the adjustment rope segments, thereby linkagely changing the size of the two rings. The spatial relationship between the adjustment rope segments and the fixed rope segments inside the knot section 3 (e.g., whether they are parallel or intersecting) depends on the arrangement of the rope segments at the start of weaving, which directly affects the consistency of the finished product's appearance and the feel of operation. This will be explained in detail below.

[0088] III. Internal Rope Segment Position Setting Scheme

[0089] As mentioned earlier, the linkage adjustment function of this wrist cord originates from the specific structure within the knot section 3, which consists of adjusting and fixing rope segments. This section details the two key weaving starting schemes that determine the final form of this structure and their impact on the finished product.

[0090] 1. Parallel Structure

[0091] As shown in Figure 3 (E1), which is a schematic diagram of the weaving start, and in Figure 3, a perspective view showing only the adjusting rope segment inside the finished product (E2), and a perspective view showing both the adjusting rope segment and the fixed rope segment inside the finished product (E3), it can be seen that at the beginning of weaving, this scheme arranges the adjusting rope segment (i.e., the continuous second rope segment 1b and the fourth rope segment 2d) and the fixed rope segment (e.g., an extension of one of the first rope segment 1a and the third rope segment 2c) in parallel on the weaving path of the knot part 3, without intersecting each other, through specific rope segment placement.

[0092] Implementation and Features: Before weaving, the second rope segment 1b and the fourth rope segment 2d are intentionally placed on the same side of the weaving path (e.g., the right side shown in (E1) of Figure 3), while an extension of either the first rope segment 1a or the third rope segment 2c is placed on the other side as a fixing rope segment. Weaving then proceeds. This arrangement ensures that after the weaving is completed, the adjusting rope segment and the fixing rope segment are parallel and side-by-side inside the knot portion 3.

[0093] Finished product effects and advantages:

[0094] Structural determinism: As shown in Figures 3(E2) and (E3), through the aforementioned weaving initiation arrangement, the second rope segment 1b of the finished wristband's opening 1 and the fourth rope segment 2d of the wristband's opening 2 are necessarily located on the same side of the knot portion 3. This deterministic structure brings the following core advantages:

[0095] Optimized operating logic: Since the adjustable parts of the two loops (second rope segment 1b and fourth rope segment 2d) are on the same side, the direction of force and the operating feel are highly consistent when the user adjusts either loop, which is intuitive and not easy to confuse, significantly improving the ease of use of the product.

[0096] This structure lays an ideal foundation for label placement: the first rope segment 1a of the device's opening 1 naturally sits alone on the other side. Label 4 (as shown in Figure 4(G)) is placed here, providing the clearest and most effective guidance for "indicating that the adjusting rope segment is on the unlabeled side" (see Section 4, "Label Placement Scheme"), thus perfectly realizing the label's functions of preventing misoperation and providing physical positioning.

[0097] 2. Intersecting structures

[0098] As shown in Figure 3 (F1), the weaving start diagram, and the perspective view (F2) showing only the adjustment rope segment inside the finished product, and the perspective view (F3) showing both the adjustment rope segment and the fixed rope segment inside the finished product, it can be seen that the different placement of the rope segments at the start of weaving in this scheme results in the adjustment rope segment and the fixed rope segment being intersected inside the knot part 3.

[0099] Implementation method and features: By adjusting the relative positions of each rope segment at the start of weaving, for example, by placing the adjusting rope segment and the fixed rope segment opposite to each other or at an angle on the weaving path, after weaving, the two will cross inside the knot.

[0100] Finished product effect: As shown in (F2) and (F3) of Figure 3, in this structure, the second rope segment 1b of the device ring 1 and the fourth rope segment 2d of the wrist ring 2 are located on different sides of the knot part (3) on the finished product. This structure can also realize the aforementioned linkage adjustment function, but the adjustable sides of the two rings are spatially separated.

[0101] 3. Summary of the Plan

[0102] Both parallel and intersecting structures can achieve the core linkage adjustment function of this invention. The parallel structure, through its operational consistency, aesthetic regularity, and perfect integration with the label function, provides a superior user experience and is the preferred solution recommended for implementation in this invention. The intersecting structure demonstrates the flexibility of this weaving method in achieving the same core function.

[0103] IV. Label Setting Scheme

[0104] In practical use of the wrist strap of this invention, it was found that both the device opening 1 and the wrist opening 2 have a sliding adjustment rope segment (i.e., the second rope segment 1b and the fourth rope segment 2d) and a locked fixed rope segment (i.e., the first rope segment 1a and the third rope segment 2c). For users unfamiliar with the structure, it is difficult to distinguish between the two from the appearance, leading to two types of problems: first, the user may repeatedly try to pull the fixed rope segment that cannot be moved, resulting in adjustment failure; second, if the user accidentally pulls the adjustment rope segment out excessively, it may cause the corresponding opening to retract completely into the knot and be difficult to restore.

[0105] To address the problem of users struggling to identify the correct target in practical use, this invention provides an optimized solution for setting label 4.

[0106] As shown in Figure 4(G), in one embodiment, the label 4 is disposed on the first rope segment 1a of the device ring 1, and located near the knot portion 3. The label 4 can be a marker fixed to the rope body, forming a significant visual or tactile distinction. Its core function is to serve as a visual or tactile marker to indicate that the adjusting rope segment (consisting of the second rope segment 1b and the fourth rope segment 2d) is located on the side of the device ring 1 where the label 4 is not disposed.

[0107] Preferably, the label 4 can be implemented in any of the following ways:

[0108] 1. A woven label measuring approximately 4 cm × 1.5 cm is used, with creases or stitching at both ends for easy bending. For securing, it is wrapped around the first rope segment 1a of the device's opening 1, approximately 2.5 turns, and then secured by hand sewing or fabric glue.

[0109] 2. A pre-made ring tag is used, which can be made of fabric, soft rubber, or other soft materials. The ring tag can be pre-attached and fixed to the rope segment; or it can be attached before weaving, positioned at the designated location after weaving, and fixed by sewing or gluing.

[0110] 3. Use a piece of thread that contrasts sharply with the color of the rope to wrap around the first rope segment (1a) multiple times at a designated position to form a raised colored segment, which is then fixed as a label 4.

[0111] Its working mechanism and beneficial effects are as follows: The label 4 improves the usability and reliability of the product by providing clear visual guidance. First, it clearly indicates the location of the adjustment rope segment (i.e., the pullable side), guiding the user to pull the correct rope segment (second rope segment 1b), thereby eliminating invalid attempts to pull the fixed rope segment. Second, it acts as a physical limiting structure integrated into the rope body. When the user pulls the adjustment rope segment to attempt adjustment, the raised part of this label can abut against the knot part 3, thereby physically preventing the second rope segment 1b of the device ring 1 from being pulled out excessively, fundamentally eliminating the possibility of structural failure of the device ring 1 due to misoperation. In summary, this design significantly reduces the probability of misoperation and improves the usability and overall durability of the product through clear guidance and physical limiting.

[0112] As shown in Figure 4(H), in another embodiment, the label 4 may also be located on the third rope segment 2c of the wristband 2, near the knot portion 3. In this configuration, the label 4 also serves to indicate that the adjustment rope segment (another component of which is the fourth rope segment 2d) is located on the side of the wristband 2 where the label 4 is not located.

[0113] As shown in Figure 4(I), in another embodiment, labels 4 can be simultaneously placed on both the first rope segment 1a of the device's opening 1 and the third rope segment 2c of the wrist opening 2. This creates symmetrical visual and physical positioning guidance on both sides of the product. This design eliminates the reliance on the internal rope segment arrangement, ensuring clear guidance at all times; and simultaneously provides fail-safe protection for both openings, improving operational certainty and product durability.

[0114] V. Rope Thickness Adjustment Scheme

[0115] Furthermore, when adapting the wrist strap described in this invention to different models of portable electronic devices, it was found that due to the varying sizes of wristband connecting rings or interfaces on different devices (especially cameras), using a fixed diameter (e.g., 4 mm) of paracord may present compatibility issues as it cannot fit into smaller interfaces. Simply adding adapter rings or other connectors would not only introduce new breakage risks but also contradict the core design advantages of this invention, which avoids scratching devices by eliminating metal and plastic connectors. If finer-gauge (e.g., 3 mm or 2 mm) paracord is used directly, the thinness of the cord can cause discomfort to the hand when worn, and its load-bearing strength is often difficult to guarantee. Moreover, commercially available paracords of different diameters are usually not interchangeable in terms of material, pattern, and color, making it difficult to ensure consistent appearance within the same product series. Customizing specific fine-diameter paracords to ensure color and pattern matching presents the challenges of huge minimum order quantities (e.g., several thousand meters for a single color) and high costs, which is impractical for a wrist strap product with multiple color options and a single-piece material consumption of only about 1.5 meters, both in terms of production and inventory management.

[0116] To address the issue of matching rope thickness with the device interface discovered during practical adaptation, and to overcome the numerous shortcomings of traditional solutions, this invention further provides an optimized solution with adjustable core pulling.

[0117] As shown in Figure 5, the thickness of the paracord can be flexibly adjusted before weaving. Specifically, as shown in (J) of Figure 5, the paracord is a high-strength paracord with an abrasion-resistant outer sheath 5 and at least two separable independent load-bearing inner cores 6. Preferably, the high-strength paracord includes seven or nine separable independent load-bearing inner cores 6, and the paracord diameter is 4 mm or more. Before weaving, depending on the specific size of the target device interface, at least one strand can be partially removed from the at least two separable independent load-bearing inner cores 6 of the paracord (preferably, two to five strands can be removed from the seven or nine inner cores, more preferably, four strands can be removed from the seven inner cores, as shown in (K) of Figure 5), thereby reducing the diameter of the wrist cord after weaving to accommodate electronic device interfaces of different sizes. This operation must be performed while ensuring that the integrity of the abrasion-resistant outer sheath 5 of the paracord is not damaged. Under this premise, by partially removing the independent load-bearing inner core 6, the final diameter and stiffness of the rope can be effectively reduced, allowing it to easily pass through smaller connecting rings or holes, while maintaining a suitable rope size and structure to ensure wearing comfort.

[0118] It should be noted that the paracord preferably used in this invention (such as a seven-core paracord with a breaking strength of approximately 160 kg) has an extremely high safety margin in its original strength. After the aforementioned core-removal treatment, the strength retained by the cord is still far higher than the static load generated by the weight of portable electronic devices (typically weighing less than 2 kg), and there is sufficient margin to cope with the occasional dynamic load in daily use. Structurally, the inner core of the paracord bears the core tension, while the abrasion-resistant outer sheath 5 is used to protect the inner core, resist wear, and maintain the overall shape. Based on this structural characteristic, the integrity of the abrasion-resistant outer sheath 5 becomes a direct and reliable basis for judging whether the load-bearing structure of the inner core is damaged. This brings significant convenience to users: in daily use, a simple visual inspection is all that is needed to confirm that the abrasion-resistant outer sheath 5 is intact and not broken to the point of exposing the independent load-bearing inner core 6, which is a quick assessment of the wrist cord's safety condition without any professional tools or complex knowledge. This convenient safety inspection method based on structural design is also applicable to conventional wrist cords that have not undergone core-removal treatment, and because their inner cores are intact, they have an even higher safety margin.

[0119] It is worth noting that, furthermore, the aforementioned technique of adjusting the physical properties of paracord by removing the core has broader applicability and can be similarly applied to other situations where there are specific dimensional and aesthetic requirements for woven components. A typical application is the creation of flexible sliding locking components that are visually integrated with the main drawstring. For example, in the drawstring opening and closing structures of products such as drawstring bags and clothing, if the same untreated paracord is directly used to weave the locking component (such as weaving two to three slip knots), the finished product will be bulky due to the inner core filling, resulting in a visual disproportion with the drawstring. However, by pre-removing all or most of the inner core of that section of paracord, retaining the soft outer sheath for weaving, the final volume and density of the resulting locking component can be precisely controlled, making it appear as a delicate and tight knot. The key effect of this process is that the locking component is completely consistent with the main drawstring in terms of material, color, and visual texture, as if it were naturally formed by the drawstring itself, while retaining its function as an independent sliding component. This not only solves the design problem of incoordination between functional components and the main visual, but also avoids the abruptness that may be caused by using heterogeneous materials for the sliding buckle, achieving a high degree of unity between functional structure and aesthetic form.

[0120] In summary, this adjustable core-pulling scheme and the technical concept it embodies represent a key technological extension of the standardized braiding structure of this invention in achieving multi-functional optimization. It not only enables standardized products based on the same core design, color, and pattern to be adapted to a series of devices, from large SLR cameras to compact mirrorless cameras, simply by adjusting the number of cores pulled, thus achieving a highly efficient unification of standardized design and diverse terminal adaptation needs; it also provides a sophisticated and universal material processing technology to solve the design challenge of coordinating functional components with the overall visual appeal of braided products.

[0121] VI. Treatment of the break and decorative ending

[0122] In one embodiment, both ends of a single paracord are located at the connection between the device loop 1 and the knot portion 3 (as shown in Figure 1(B)) or at the connection between the wrist loop 2 and the knot portion 3 (as shown in Figure 1(A)).

[0123] As shown in (L) of Figure 6, in another embodiment, to further enhance the stability of the knot portion 3, improve product durability, and add aesthetic appeal, the two ends of a single paracord are extended from the joint and woven into decorative ends 3e and 3f. Decorative ends 3e and 3f include, but are not limited to, the phoenix tail knot (as shown in (L) of Figure 6), dragonfly knot, pumpkin knot, double overhand knot, barrel knot, or lark's head knot, etc., which are common ends in the field of weaving or knotting and are well known to those skilled in the art.

[0124] This setting has the following technical effects:

[0125] Firstly, regarding structural stability, the decorative ends 3e and 3f significantly enhance the overall structural integrity and long-term reliability of the product through a dual mechanism. Firstly, compared to directly sintering and concealing the break at the connection between the device's ring 1 or wrist ring 2 and the knot portion 3, extending the break and weaving it into decorative ends 3e and 3f allows for thorough sintering and fixation within the decorative ends 3e and 3f. The sintered structure is completely enclosed and protected by the knot body of the decorative ends 3e and 3f, thus eliminating the possibility of the knot portion 3 accidentally unraveling from the end without affecting the appearance. Secondly, the decorative ends 3e and 3f (such as a phoenix tail knot) themselves constitute an effective physical restraint structure, actively constraining the rope strands and further preventing the knot portion 3 from accidentally unraveling during use. In contrast, the direct sintering scheme faces a dilemma: insufficient sintering for aesthetic purposes carries the risk of loosening; excessive sintering for strength results in hardened knots that affect aesthetics. This embodiment avoids this contradiction.

[0126] Secondly, in terms of maintainability and user experience, the decorative ends 3e and 3f provide convenient active maintenance functions and further enhance safety during temporary operations. The key is that the braided decorative ends 3e and 3f inherently retain an extra length of rope as a margin for operation. If a direct sintering method is used, once the knot loosens, the break may retract inwards, making it difficult to restore due to the lack of margin. In this embodiment, however, the user can easily utilize this length margin by gently pulling on the two decorative ends 3e and 3f to tighten the core-buried knot back to a tight state. Simultaneously, the decorative ends 3e and 3f not only provide a convenient gripping and force-applying operating area for maintenance, but their raised structure also effectively prevents slippage and limits movement when the user temporarily holds the knot portion 3 to move the device, preventing accidental slippage and thus improving safety and controllability in various operating postures. These designs greatly enhance the product's maintainability, lifespan, and overall user experience.

[0127] Furthermore, this embodiment chooses to treat the break ends as decorative finishes 3e and 3f, a comprehensive design deeply aligned with the core application scenario of secure grip for valuable portable electronic devices. In this scenario, user requirements for accessories are complex: they demand extremely high safety and reliability to withstand the weight of the device and dynamic impacts, a refined appearance to match the expensive equipment, and long-term durability and maintainability. A single sintering process cannot simultaneously meet these requirements. This embodiment introduces decorative finishes 3e and 3f, an optimized solution for this complex need. It is not a simple application of existing knotting techniques, but a creative choice made after a deep understanding of the synergistic requirements of structural strength, aesthetic quality, and user experience in a specific application scenario. This design allows the product to achieve its core functions (linked adjustment, reliable load-bearing capacity) while its detailed craftsmanship meets the reliability standards and aesthetic harmony required for high-end portable electronic device accessories.

[0128] In summary, this embodiment cleverly unifies structural strength, durability, aesthetics, and maintainability by introducing decorative endings 3e and 3f, achieving a superior overall technical effect compared to simple sintering.

[0129] VII. Weaving Method

[0130] This section, in conjunction with Figure 3, describes an exemplary method for weaving the wrist cord of the present invention. First, a paracord of predetermined length is provided. This paracord can be a standard seven-core or nine-core structure, and according to Section V, "Cord Thickness Adjustment Scheme," it can be subjected to core-pulling treatment before weaving. Those skilled in the art will understand that the following basic weaving method and optimized weaving method are both used to produce products with the following core structure: woven from a single paracord, and the linkage adjustment between the device opening 1 and the wrist opening 2 is achieved through the knot portion 3.

[0131] 1. Basic knitting methods

[0132] The method includes the following steps:

[0133] S1. Rope segment preparation: The rope body of a single paracord of a predetermined length (e.g., 1.5 meters) is divided to define the first rope segment 1a and the second rope segment 1b that will form the device loop 1, the third rope segment 2c and the fourth rope segment 2d that will form the wrist loop 2, and the two weaving rope segments (composed of the extensions of the first rope segment 1a and the third rope segment 2c) for weaving.

[0134] S2. Forming a ring: The first rope segment 1a and the second rope segment 1b are joined together to form a device ring 1; the third rope segment 2c and the fourth rope segment 2d are joined together to form a wrist ring 2.

[0135] S3. Setting the internal rope segment: The continuous portion of the second rope segment 1b and the fourth rope segment 2d is determined as the adjusting rope segment. Simultaneously, one of the first rope segment 1a and the third rope segment 2c is determined as the fixed rope segment. The adjusting rope segment and the fixed rope segment together serve as the two internal rope segments in subsequent weaving.

[0136] S4. Weaving a core-filled knot: The two weaving rope segments are wrapped around and covered to form a knot portion 3, which is a core-filled knot structure. The core-filled knot is preferably a core-filled snake knot. It should be understood that other weaving methods that can form a core-filled structure and allow the woven body and the adjusting rope segment to slide relative to each other are also applicable, such as a core-filled diamond knot, a core-filled flat knot, a core-filled lock knot, a core-filled dragon scale knot, or a core-filled four-strand braid. This step establishes a relatively sliding relationship between the woven body formed by the weaving rope segments and the adjusting rope segment.

[0137] In this basic method, the relative spatial positions of each rope segment at the starting point of weaving during the rope segment preparation in step S1, especially the relative positions between the second rope segment 1b and the fourth rope segment 2d, which ultimately constitute the adjustment rope segment, are not deliberately constrained. During the weaving process, they may be located on any opposite side of the knot section 3 (for example, they may be located on the left and right sides of the knot, as shown in (F1), (F2), and (F3) in Figure 3). In this case, although the completed wrist rope has the aforementioned linkage adjustment function, the spatial relationship between the second rope segment 1b of the device loop 1 and the fourth rope segment 2d of the wrist loop 2 on the finished product may be random. This may result in inconsistent tactile feedback and directional sense for the user when adjusting the loops on both sides.

[0138] 2. Optimize weaving methods

[0139] To address the inconsistencies in user experience that may arise from the aforementioned basic weaving method, and to create optimal structural conditions for further setting up function label 4, this invention provides an optimized weaving method. This optimized method adds a position arrangement step after setting the core rope in S3 and before weaving the knot in S4 of the basic method:

[0140] S3a: Positioning. Adjust the relative spatial positions of each rope segment to ensure that the second rope segment 1b and the fourth rope segment 2d are positioned on the same side of the weaving path (e.g., the right side as shown in (E1) in Figure 3). This means that the adjusting rope segment and the fixing rope segment are parallel and side by side in the internal spatial relationship of the knot section 3.

[0141] After completing this key arrangement, proceed to step S4 to weave the core-wrapped knot. Due to this initial preset state, after weaving, the second rope segment 1b of the device loop 1 and the fourth rope segment 2d of the wrist loop 2 will be located on the same side of the finished wrist rope knot portion 3 (as shown in (E2) and (E3) in Figure 3).

[0142] This layout yields technical results that are superior to basic weaving methods:

[0143] This provides an ideal basis for setting label 4: the first rope segment 1a of the device ring 1 is therefore located on the other side, and when label 4 is set in this position, its function of "indicating that the adjusting rope segment is located on the side of the device ring 1 where label 4 is not set" is most clear, effective, and easy to manufacture.

[0144] Optimize operation logic and user experience: Since the adjustment rope segments (second rope segment 1b and fourth rope segment 2d) are on the same side, the direction of force and feel are more consistent and intuitive when adjusting, which significantly reduces the possibility of confusion and misoperation.

[0145] 3. Subsequent and Optional Steps

[0146] Regardless of whether a basic or optimized weaving method is used, the same follow-up processing can be performed after the main structure of the wrist cord is woven: the broken ends are sintered to hide them or decorative ends 3e, 3f are woven (as shown in (L) in Figure 6); and / or, according to the product design, a label 4 is fixedly set on the first cord segment 1a of the device loop 1 (as shown in (M) in Figure 6).

[0147] In summary, the weaving method of the present invention, especially the optimized method including the position arrangement in step S3a, can not only reliably produce core products with linkage adjustment functions, but also ensure the product has the best operational consistency and user experience through preset arrangement, while providing a key process foundation for subsequent functional expansion (such as label setting) and production adaptation.

[0148] VIII. Application Scenarios and Extended Functions

[0149] As shown in Figures 2 and 7, the braided wrist strap of this invention is not only suitable for cameras but can also be used as a lanyard for mobile phones, effectively reducing the risk of phones falling, especially during outdoor activities or in crowded places, providing users with a convenient and safe way to carry their devices. Furthermore, this wrist strap can also be used to carry various other portable electronic devices, such as portable music players, e-readers, and small game consoles, meeting users' needs in different scenarios.

[0150] The above embodiments fully demonstrate that the present invention achieves linkage adjustment and safety assurance without the need for external accessories through a specific weaving structure and rope segment planning. The resulting product has an integrated structure, smooth adjustment, safety and durability, and precisely meets the specific needs of holding valuable portable electronic devices such as cameras and mobile phones securely, possessing significant practical advantages.
