Description

Technical Field

[0001] This utility model relates to the field of rope ladder technology, specifically a ring rope and a novel rope ladder made from the ring rope. Background Technology

[0002] In the field of rope ladder manufacturing, traditional rope ladders typically employ a structure with two main ropes and sewn webbing (such as...). Figure 1 As shown in the diagram, the specific construction method is as follows: First, select two thick ropes as the main ropes and mark the position of each footboard on both ropes, ensuring that the marks on the two main ropes are aligned; then, sew a thick first webbing between the marked positions on the two main ropes using a sewing machine; finally, sew a second webbing onto the back of the first webbing and sew the two webbings together to form the footboard structure. However, this traditional rope ladder structure has the following drawbacks:

[0003] 1. Traditional rope ladders use two thick main ropes and double-layer thick webbing, which results in redundant materials, increasing the overall weight of the rope ladder and making it inconvenient to carry.

[0004] 2. The load capacity of traditional rope ladders is related to the load-bearing capacity of the main rope and webbing. If the load needs to be increased, the main rope or webbing must be replaced with a thicker one, which lacks adaptability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a ring rope and a novel rope ladder. The load capacity is adjusted by changing the number of loops in the ring yarn coil; as the number of loops increases, the load-bearing capacity increases. An outer ring sleeve provides excellent wear-resistant protection, maintaining the morphological stability and operational reliability of the internal ring yarn coil. The novel rope ladder is formed by twisting a single ring rope, a simple and convenient process. The size of the ladder can be adjusted by creating ring ropes of different circumferences. Furthermore, the winding length and number of loops of the second reinforcing layer and second covering layer, sequentially wound at the intersection of adjacent ring units, can be adjusted as needed. As the winding length and number of loops increase, the load-bearing capacity of the rope ladder increases, and footboards of varying lengths can be created to meet different needs.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] This utility model provides a ring rope, comprising:

[0008] A looped yarn is made by winding yarn.

[0009] A loop is provided outside the annular yarn loop;

[0010] The loop is formed by wrapping a flat fabric around the outside of the annular yarn loop and then stitching it together; or the loop is a tubular fabric with a hollow channel, the yarn is threaded through the tubular fabric and wound along the hollow channel of the tubular fabric to form the annular yarn loop, and the two ends of the tubular fabric are stitched together.

[0011] Furthermore, when the ring is a tubular fabric, the tubular fabric includes one of hollow rope, water pipe rope, or hollow webbing.

[0012] Furthermore, when the ring is made of tubular fabric, the two ends of the tubular fabric are overlapped and then sewn together by a sewing machine.

[0013] Furthermore, the yarn is one of ultra-high molecular weight polyethylene fiber, high-strength nylon yarn, aramid, and polyester yarn.

[0014] Furthermore, a first reinforcing layer is wound around a portion of the loop rope, and the outer periphery of the first reinforcing layer covers a first covering layer and is fixed by stitching.

[0015] Furthermore, when the ring is a tubular fabric, the first reinforcing layer is disposed at the stitched connection positions at both ends of the tubular fabric.

[0016] Furthermore, the first reinforcing layer is one or more of webbing, rope, and yarn.

[0017] Furthermore, the surface of the first coating layer is provided with an anti-slip structure.

[0018] This utility model also provides a novel rope ladder, including the aforementioned ring rope, which forms multiple ring units after being twisted several times. A second reinforcing layer is wound around the intersection of adjacent ring units, and the outer periphery of the second reinforcing layer covers the second covering layer and is fixed by sewing.

[0019] Furthermore, the second reinforcing layer is stitched and fixed at the intersection of the adjacent annular units.

[0020] Furthermore, before the second reinforcing layer is applied, the adjacent annular units are stitched together at their intersections.

[0021] Furthermore, the second reinforcing layer is one or more of webbing, rope, and yarn.

[0022] Furthermore, the surface of the second coating layer is provided with an anti-slip structure.

[0023] Furthermore, the multiple ring units may be the same or different in size.

[0024] Compared with the prior art, the advantages of this utility model are as follows:

[0025] 1. The load limit of the circular rope of this utility model can be adjusted by adjusting the number of loops of the circular yarn coil. As the number of loops increases, its load-bearing capacity increases. The outer ring of the circular yarn coil can provide excellent wear-resistant protection to maintain the morphological stability and working reliability of the internal circular yarn coil.

[0026] 2. The ring of this utility model is a tubular fabric with a hollow channel. The yarn is wound into a ring-shaped yarn loop along the hollow channel of the tubular fabric. The forming is simple, and there are no other connection marks except at the connection positions at both ends of the tubular fabric. The overall structure is neat and beautiful.

[0027] 3. The first reinforcing layer and the first covering layer are sequentially wound around several parts of the ring rope of this utility model and then fixed by sewing to form the hanging ring, foot pedal and other parts on the ring rope. The first reinforcing layer and the first covering layer can improve wear resistance and durability. The winding length and number of turns of the first reinforcing layer and the first covering layer can be set as needed to meet different requirements.

[0028] 4. The first reinforcing layer and the first covering layer of this utility model are set at the stitching positions at both ends of the tubular fabric to avoid unnecessary stitching marks and maintain the neatness and beauty of the overall structure.

[0029] 5. The novel rope ladder of this utility model is formed by twisting a single loop rope, which is simple and convenient. The size of the new rope ladder can be adjusted by making loop ropes of different circumferences, and its upper load limit can be adjusted by adjusting the number of loops of yarn.

[0040] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0041] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms "first" and similar words as used in this utility model specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

[0042] like Figure 2-5 As shown, this utility model provides an annular rope 1, including an annular yarn loop 11 made of yarn 111 and a ring 12 disposed outside the annular yarn loop 11.

[0043] In one embodiment, the loop 12 is formed by wrapping a flat fabric around the outside of the annular yarn loop 11 and then sewing them together. For example, the flat fabric can be various abrasion-resistant cloths, webbing, etc. After the yarn 111 is wound into an annular yarn loop 11, the flat fabric is wrapped around the outside of the annular yarn loop 11 and then sewn together to secure it.

[0044] In another embodiment, such as Figure 2 , Figure 3 As shown, the loop 12 is a tubular fabric 121 with a hollow channel. The yarn 111 is threaded through the tubular fabric 121 and wound along the hollow channel to form the annular yarn loop 11. The two ends of the tubular fabric 121 are sewn together. For example, the tubular fabric 121 may include a hollow rope, a water pipe rope, or a hollow webbing. The material, inner diameter, and wall thickness of the tubular fabric 121 can be selected differently depending on the requirements. In this embodiment, the loop 12 is a single piece of tubular fabric 121, which is simple to manufacture, and there are no other connection marks except at the connection points at both ends of the tubular fabric 121, resulting in a neat and aesthetically pleasing overall structure.

[0045] Preferably, the two ends of the tubular fabric 121 are overlapped and then sewn together by a sewing machine. After the two ends of the tubular fabric 121 are overlapped, it is not only convenient to sew by a sewing machine, but also to improve the connection strength.

[0046] The load limit of the annular rope 1 of this invention can be adjusted by adjusting the number of turns of the annular yarn coil 11. As the number of turns of the annular yarn coil 11 increases, its load-bearing capacity increases. The annular yarn coil 11 is built into the ring sleeve 12, which can provide excellent wear-resistant protection to maintain the morphological stability and working reliability of the internal annular yarn coil 11.

[0047] Furthermore, the yarn 111 is one of ultra-high molecular weight polyethylene fiber, high-strength nylon yarn 111, aramid, and polyester yarn 111.

[0048] Furthermore, a first reinforcing layer 13 is wound around several portions of the loop rope 1, and a first covering layer 14 covers the outer periphery of the first reinforcing layer 13 and is fixed by stitching. The first reinforcing layer 13 and the first covering layer 14 allow this portion of the loop rope 1 to function as a hanging loop, foot pedal, etc., improving wear resistance and durability. The winding length and number of turns of the first reinforcing layer 13 and the first covering layer 14 can be set as needed to meet different requirements. For example, the first reinforcing layer 13 and the first covering layer 14 can be wound around one portion of the loop rope 1 to form a hanging loop, foot pedal, etc.; or... Figure 5 As shown, a first reinforcing layer 13 and a first covering layer 14 are wound around two opposite regions of the loop rope 1 to form two hanging rings, foot pedals, and other parts.

[0049] Furthermore, when the ring 12 is a tubular fabric 121, the first reinforcing layer 13 is disposed at the stitching connection position at both ends of the tubular fabric 121 to avoid excessive stitching marks and maintain the neatness and aesthetics of the overall structure.

[0050] Furthermore, the first reinforcing layer 13 can be one or more of webbing, rope, and yarn. The yarn can be high-strength yarns such as ultra-high molecular weight polyethylene fiber, high-strength nylon yarn, aramid yarn, and polyester yarn. Different materials can be selected to wind the first reinforcing layer 13 according to different requirements.

[0051] Furthermore, the surface of the first covering layer 14 is provided with an anti-slip structure.

[0052] like Figures 6-8 As shown, this utility model also provides a novel rope ladder, including the aforementioned ring rope 1. The ring rope 1, after being twisted several times, forms multiple ring units 15. A second reinforcing layer 2 is wound around the intersection of adjacent ring units 15. A second covering layer 3 is wrapped around the outer periphery of the second reinforcing layer 2 and then stitched together for fixation. When the loop 12 of the ring rope 1 is a tubular fabric 121 with a hollow channel, the connection points at both ends of the tubular fabric 121 can serve as the intersection points of adjacent ring units 15 for winding the second reinforcing layer 2.

[0053] This novel rope ladder is formed by twisting a single loop rope 1. The size of the ladder can be adjusted by making loop ropes 1 with different circumferences. The load capacity can also be adjusted by changing the number of loops in the loop yarn coil 11. As the number of loops increases, the load-bearing capacity increases. Furthermore, the winding length and number of loops of the second reinforcing layer 2 and the second covering layer 3, sequentially wound at the intersection of adjacent loop units 15 formed by twisting, can be adjusted as needed. With increasing winding length and number of loops, the load-bearing capacity of the rope ladder increases, and different lengths of footholds can be created to meet various needs. This novel rope ladder has the advantages of being lightweight, high-strength, and simple to manufacture.

[0054] Furthermore, the second reinforcing layer 2 is one or more of webbing, round rope, and yarn. The yarn can be high-strength yarns such as ultra-high molecular weight polyethylene fiber, high-strength nylon yarn, aramid yarn, and polyester yarn. Different materials can be selected to wrap the second reinforcing layer 2 according to different needs. By wrapping the webbing, round rope, or high-strength yarn around the intersection of adjacent annular units 15, the structure of the rope ladder is initially fixed, which facilitates the subsequent sewing of the second covering layer 3. Different numbers of turns and lengths can be wrapped as needed to provide different specifications of load-bearing capacity and stepping positions.

[0055] Furthermore, the second reinforcing layer 2 is sewn and fixed at the intersection of the adjacent annular units 15. Specifically, after the second reinforcing layer 2 is wound, it can be fixed by sewing with a sewing machine to facilitate the fixation of the second reinforcing layer 2, avoid misalignment, and improve the fixation strength of adjacent annular units 15.

[0056] Furthermore, before wrapping the second reinforcing layer 2, the adjacent annular units 15 are stitched together at their intersections. This facilitates determining the connection positions of the annular units 15, avoids misalignment, and also facilitates the subsequent wrapping of the second reinforcing layer 2.

[0057] Furthermore, the surface of the second covering layer 3 is provided with an anti-slip structure to improve the anti-slip performance of the double-ring fitting rope ladder.

[0058] Furthermore, the multiple ring units 15 may be the same or different in size, and the ring rope 1 can be twisted into ring units 15 of any size as needed to improve practicality.

[0059] In this utility model, the stitching of the ring 12, the first reinforcing layer 13, the first covering layer 14, the stitching connection between adjacent annular units 15, the second reinforcing layer 2, the second covering layer 3, etc., can all be done by sewing machine. The sewing machine method includes, but is not limited to, DY sewing machine, flat sewing machine and computer sewing machine. The sewing machine pattern also includes, but is not limited to, herringbone pattern, straight line and overlock, the purpose of which is only to fix and increase the tensile strength. Different sewing machine methods can be selected according to the required tensile strength.

[0060] Taking the tubular fabric 121 as the loop 12 as an example, the manufacturing method of the annular rope and the novel rope ladder of this utility model is specifically described:

[0061] (1) Take a tubular fabric 121 and pass the starting end of the yarn 111 through the hollow channel of the tubular fabric 121 (e.g., Figure 2 (as shown);

[0062] (2) Then tie the starting end of yarn 111 to the yarn 111 that has not passed through the tubular fabric 121 (e.g. Figure 3 (as shown);

[0063] (3) Take an arc segment of the already formed loop yarn and press it onto the power wheel 4 of the winding machine (at this time, the tubular fabric 121 can be compressed to leave a gap for the loop yarn). Then let the power wheel 4 rotate and continuously let the yarn 111 be wound in the hollow channel of the tubular fabric 121 until the required number of windings is reached. Cut off the excess yarn 111 and connect the end of the yarn to the beginning end or tie the end of the yarn to the already formed loop yarn to form the required loop yarn 11.

[0064] (4) Cut the tubular fabric 121 to a length that matches the circumference of the loop yarn 11 (preferably, the length of the tubular fabric 121 should be longer than the circumference of the loop yarn 11), and after the two ends of the tubular fabric 121 are fitted, sew them together using a sewing machine to form a loop rope 1 (e.g., Figure 4 (As shown).

[0065] The above are the manufacturing steps of the loop rope 1. As needed, the first reinforcing layer 13 can be wrapped around the loop rope 1 and sewn together. The first covering layer 14 is then rolled around the outer periphery of the first reinforcing layer 13 and sewn together.

[0066] The new rope ladder is made using the aforementioned circular rope 1, and includes the following steps:

[0067] (5) Figure 6 As shown, after twisting the loop rope 1, two adjacent loop units 15 are formed, and the two loop units 15 are sewn together at the intersection. The above operation is repeated at different positions to form the preliminary rope ladder with multiple loop units 15 as required.

[0068] (6) Figure 7 As shown, the second reinforcing layer 2 is wrapped with webbing, round rope or strong yarn at the intersection of adjacent ring units 15, and the intersection area of ​​the two ring units 15 is fixed with a sewing machine.

[0069] (7) Figure 7 As shown, a second covering layer 3 is rolled around the outer periphery of the second reinforcing layer 2 and fixed by sewing to form a foot pedal position that is easy to step on. The second covering layer 3 can be made of webbing, and different numbers of turns can be rolled as needed. The above operation is repeated at the intersection of multiple ring units 15 to make a rope ladder (such as... Figure 8 (As shown).

[0070] Those skilled in the art should understand that the specific embodiments described above are merely examples and not limitations. Various modifications, combinations, partial combinations, and substitutions can be made to the embodiments of this utility model according to design requirements and other factors, as long as they are within the scope of the appended claims or their equivalents, and thus fall within the scope of the rights to be protected by this utility model.
