Description

Technical Field

[0001] This invention relates to the field of elastic rope technology, and more specifically to an elastic connecting rope and its weaving method. Background Technology

[0002] Elastic rope is a type of rope with resilience, and it is widely used in daily life. Elastic rope can bring many benefits to people in modern life, and its application areas are also very extensive. The principle behind elastic ropes used in the fitness field is to use the force of gravity during pulling to exercise the body and enhance the enjoyment of exercise. Elastic rope exercise for weight loss utilizes the principle and advantages of elastic ropes to help you perform full-body exercises such as strength, flexibility, stretching, and jumping anytime, anywhere, and has a good fat-reducing effect.

[0003] There are generally two types of existing elastic ropes. One type is an integrated structure, with the ends bent and connected to form a pull ring. The pull ring and the rope body have the same elasticity. During use, the pull ring will also deform under tension, making the pull ring thinner, which can easily damage the internal core and reduce grip comfort. The other type is a split structure, such as the elastic rope with easily identifiable ends disclosed in utility model patent CN214209290U. It includes an elastic rope with connecting blocks at both ends. The connecting blocks are symmetrically equipped with fixing sleeves. The fixing sleeves are cylindrical, with a through groove in the middle of the top of the fixing sleeve. The outer circumference of the fixing sleeve is provided with threaded holes communicating with the through groove, and fastening bolts are provided in the threaded holes. A through hole is provided near the top of the side wall of the connecting block. A pull ring is provided above the connecting block, and a rotating shaft is provided at the end of the pull ring. The rotating shaft passes through the through hole. The raw materials are diverse and the process is complex.

[0004] Therefore, it is necessary to provide an elastic connecting rope and its weaving method. Summary of the Invention

[0005] The purpose of this invention is to provide an elastic connecting rope and its weaving method, so as to solve the problems of the existing elastic connecting ropes having a separate design with different materials for the connecting ring and the rope body, resulting in low connecting ring strength and complex processes due to the variety of raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An elastic connecting rope, comprising: The rope body and the connecting ropes located at both ends of the rope body are integrally woven together. The middle part of the connecting rope is bent towards the end close to the rope body, and the two ends of the connecting rope are fixed to form a loop structure. The elastic deformation of the ring structure is less than that of the rope body.

[0007] Furthermore, the rope body includes a first rope core and a first wrapping layer wrapped around the first rope core, and the connecting rope body includes a second rope core and a second wrapping layer wrapped around the second rope core. The first rope core and the second rope core are both elastic bodies made of the same material and woven integrally. The first wrapping layer wraps around the outside of the first rope core in its natural state, and the second wrapping layer tightly wraps around the outside of the second rope core in its stretched state. The first wrapping layer and the second wrapping layer are integrally formed.

[0008] Furthermore, the first and second wrapping layers are woven from ultra-high molecular weight polyethylene fiber, polyester, polyamide, polypropylene, aramid, or any one or more of the above fiber materials.

[0009] Furthermore, the weaving density of the second wrapping layer is greater than that of the first wrapping layer; or, the number of weaves in the second rope core (201) is less than the number of weaves in the first rope core (101), and the weaving density of the second wrapping layer (202) is greater than that of the first wrapping layer (102).

[0010] Furthermore, the two ends of the connecting rope are fixed by heat pressing, adhesive, or fasteners.

[0011] Furthermore, a first protective sleeve of variable length is fitted on the outside of the rope body, with both ends of the first protective sleeve fixedly connected to both ends of the rope body, and the middle part of the first protective sleeve movably connected to the rope body.

[0012] Furthermore, the connecting rope is wrapped with a second protective sleeve.

[0013] Furthermore, a connecting sleeve is fixedly provided on one end of the rope body near the connecting rope body and on the outside of the connecting position of the connecting rope body, and the two ends of the first protective sleeve are fixed between the rope body and the connecting sleeve.

[0014] A method for weaving an elastic connecting rope includes the following steps: Prepare an elastomer. The elastomer is made of the same material and the same number of weaves and is woven in one piece. Or it is made of the same material and is woven in one piece with fewer weaves at both ends than in the middle. The main body of the rope and the connecting rope are made by weaving a first wrapping layer on the outside of a first rope core, and the connecting rope is made by weaving a second wrapping layer on the outside of a second rope core. Starting from one end of the elastomer, clamp the starting end and the position near the starting end of the elastomer and stretch it to form the second rope core at one end. Alternatively, clamp the two ends of the elastomer with a smaller number of weaves near the starting end and stretch them to form the second rope core at one end. Weave a second wrapping layer outside the second rope core from the starting end. The second wrapping layer needs to be tightly woven to prevent the elastomer inside the second wrapping layer from rebounding. After the second wrapping layer near the starting end is woven, clamp the woven second wrapping layer and the position of the elastomer near the ending end, and straighten the first rope core in the middle of the elastomer in a naturally elongated state. Continue to weave the first wrapping layer outside the first rope core. The first wrapping layer elongates and retracts with the first rope core. After the first wrapping layer is woven, clamp the position of the first wrapping layer near the ending end and the ending end and stretch it to form the second rope core at the other end. Clamp the two ends of the elastomer with a smaller number of weaves near the ending end to form the second rope core at the other end. Continue to weave the second wrapping layer at the other end outside the second rope core near the ending end. To create a loop structure, fix the two ends of the connecting rope to form a loop. The fixing method can be heat pressing, adhesive, or fasteners.

[0015] Furthermore, it also includes installing a first protective sleeve, which is placed on the outside of the rope body before the ring structure is made. The length of the first protective sleeve is variable, and the two ends of the first protective sleeve are fixed to the two ends of the rope body respectively.

[0016] The present invention has the following beneficial effects: 1. The elastic connecting rope of this invention is integrally woven from the rope body and the connecting rope itself. A loop structure is formed by bending the middle of the connecting rope towards the end closer to the rope body and fixing both ends of the connecting rope. The elastic deformation of the loop structure is less than that of the rope body. Because the elastic deformation of the loop structure is less than that of the rope body, when the elastic connecting rope is subjected to tension, the deformation of the connecting rope is much less than that of the rope body. Therefore, the connecting rope will not become thinner, avoiding damage to the core, effectively extending its service life and improving grip comfort. Furthermore, the rope body and the connecting rope are integrally designed, resulting in a stronger connection between the rope body and the loop structure. Since they are made of the same material, compared to a separate structure, the elastic connecting rope of this invention uses fewer types of raw materials and has a simpler manufacturing process.

[0017] 2. The elastic connecting rope of the present invention comprises a first rope core and a first wrapping layer wrapped around the outside, and a connecting rope body comprising a second rope core and a second wrapping layer wrapped around the outside. The first rope core and the second rope core are both elastic bodies made of the same material and woven together. The first wrapping layer and the second wrapping layer are also made of the same material. The first wrapping layer wraps around the outside of the first rope core in its natural state, so that the first wrapping layer can deform to the same degree as the first rope core at the same time. The second wrapping layer tightly wraps around the outside of the second rope core in its stretched state, so as to fix the length of the second rope core, prevent the second rope core from shrinking back, and greatly reduce the degree of deformation of the connecting rope body when stretched.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example

[0021] Reference Figure 1 , Figure 3 In this embodiment, an elastic connecting rope includes a rope body 1 and connecting rope bodies 2 located at both ends of the rope body 1. The rope body 1 and the connecting rope bodies 2 are integrally woven together. The middle part of the connecting rope body 2 is bent towards the end close to the rope body 1, and the two ends of the connecting rope body 2 are fixed to form a loop structure. The elastic deformation of the loop structure is less than the elastic deformation of the rope body 1.

[0022] Among them, combined Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the rope body 1 includes a first rope core 101 and a first wrapping layer 102 wrapped around the first rope core 101. The connecting rope body 2 includes a second rope core 201 and a second wrapping layer 202 wrapped around the second rope core 201. Both the first rope core 101 and the second rope core 201 are elastic bodies 3 made of the same material, and are integrally woven together. The first wrapping layer 102 wraps around the outside of the first rope core 101 in its natural state. When subjected to external force, the first wrapping layer 102 can deform to the same degree as the first rope core 101. When the external force disappears, the first wrapping layer 102 can retract simultaneously with the first rope core 101, and the first wrapping layer 102 and the first rope core 101 can lengthen and shorten simultaneously. The second wrapping layer 202 tightly wraps around the outside of the second rope core 201 in a stretched state. The second rope core 201 is always in a stretched state, and when subjected to external force, the deformation of the second rope core 201 due to the external force is much smaller than that of the first rope core 101. Furthermore, the first wrapping layer 102 and the second wrapping layer 202 are made of the same material and are integrally formed.

[0023] Specifically, in this embodiment, the first wrapping layer 102 and the second wrapping layer 202 are woven from ultra-high molecular weight polyethylene fiber, polyester, polyamide, polypropylene, aramid, or any one or more of the above fiber materials. The specific weaving method for the first wrapping layer 102 and the second wrapping layer 202 is that the first wrapping layer 102 and the second wrapping layer 202 are woven with the same number of strands, and the weaving density of the first wrapping layer 102 is less than the weaving density of the second wrapping layer 202. This allows the first wrapping layer 102 and the first rope core 101 to stretch and contract simultaneously, while the second rope core 201 remains in a stretched state.

[0024] In this embodiment, the two ends of the connecting rope 2 are fixed to form a ring structure. Specifically, the fixing method can be heat pressing, adhesive or buckle fixing, depending on which fixing method is selected so that the two ends of the connecting rope 2 can be firmly fixed.

[0025] In this embodiment, combined with Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, an elastic connecting rope has a first protective sleeve 4 of variable length fitted over the outer side of the rope body 1. Specifically, the sleeve 4 can be made of nylon or other materials and has a corrugated tubular structure. The two ends of the first protective sleeve 4 are fixedly connected to the two ends of the rope body 1, while the middle part of the first protective sleeve 4 is movably connected to the rope body 1. The first protective sleeve 4 can extend and shorten along with the rope body 1, thereby protecting the rope body 1, effectively preventing wear and tear, and extending its service life.

[0026] Preferred, such as Figure 1 As shown, the elastic connecting rope in this embodiment also includes a connecting jacket 5. The connecting jacket 5 is fixed to one end of the rope body 1 near the connecting rope body 2 and to the outside of the connection position of the connecting rope body 2. The two ends of the first protective sleeve 4 are fixed between the rope body 1 and the connecting jacket 5. Specifically, the connecting jacket 5 can be made of materials such as heat shrink tubing or tape. The connecting jacket 5 can effectively protect the connection position of the elastic connecting rope and further enhance the firmness of the ring structure.

[0027] The outer side of the connecting rope 2 is covered with a second protective sleeve (not shown in the figure). Specifically, the second protective sleeve is wrapped around the outer side of the connecting rope 2 outside the connecting outer sleeve 5. The second protective sleeve can be made of rubber, which protects the connecting rope 2 on the one hand and increases the comfort of holding it on the other.

[0028] In this embodiment, specifically, the elastic body 3 can be the core of an existing elastic rope, for example, a multi-strand elastic rope interlaced and wound structure, such as... Figure 8 The multi-strand elastic rope internal and external arrangement structure shown is an example.

[0029] In this embodiment, the elastic connecting rope consists of a rope body 1 and a connecting rope body 2 integrally formed. A loop structure is created by bending the middle of the connecting rope body 2 towards the end closest to the rope body 1 and fixing both ends of the connecting rope body 2. The elastic deformation of the loop structure is less than that of the rope body 1. Because the elastic deformation of the loop structure is less than that of the rope body 1, when the elastic connecting rope is subjected to tension, the deformation of the connecting rope body 2 is much less than that of the rope body 1, thus preventing the connecting rope body 2 from becoming thinner. Furthermore, the integral formation of the rope body 1 and the connecting rope body 2 results in a more robust connection between the rope body 1 and the loop structure, and the materials are identical. Therefore, compared to a separate structure, the elastic connecting rope of this invention uses fewer types of raw materials and has a simpler manufacturing process.

[0030] The main rope 1 consists of a first rope core 101 and a first wrapping layer 102 wrapped around its outer side. The connecting rope 2 consists of a second rope core 201 and a second wrapping layer 202 wrapped around its outer side. Both the first rope core 101 and the second rope core 201 are integrally formed elastic bodies 3 made of the same material. Specifically, the number of braids in the first rope core 101 is the same as the number of braids in the second rope core 201, or the number of braids in the second rope core 201 is less than the number of braids in the first rope core 101. The first wrapping layer 102 and the second wrapping layer 202 are also made of the same material. The first wrapping layer 102 wraps around the outside of the first rope core 101 in its natural state, so that the first wrapping layer 102 can deform to the same degree as the first rope core 101 at the same time. The second wrapping layer 202 tightly wraps around the outside of the second rope core 201 in its stretched state, so as to fix the length of the second rope core 201, prevent the second rope core 201 from shrinking back, and greatly reduce the degree of deformation of the connecting rope 2 when stretched.

[0031] This embodiment describes a method for weaving an elastic connecting rope, comprising the following steps: Prepare elastomer 3. Elastomer 3 is made of the same material and the same number of weaves and is woven in one piece / made of the same material and the number of weaves at both ends is less than the number of weaves in the middle and is woven in one piece.

[0032] The rope body 1 and the connecting rope body 2 are made. The rope body 1 is made by weaving a first wrapping layer 102 on the outside of the first rope core 101, and the connecting rope body 2 is made by weaving a second wrapping layer 202 on the outside of the second rope core 201.

[0033] Starting from one end of the elastic body 3, the starting end and the position near the starting end of the elastic body 3 are clamped and stretched to form a second rope core 201 at one end. The two ends of the elastic body 3 with a smaller number of braids near the starting end are also clamped and stretched to form another second rope core 201 at one end. A second wrapping layer 202 is then braided outside the second rope core 201 from the starting end. The second wrapping layer 202 needs to be tightly braided to prevent the elastic body 3 inside the second wrapping layer 202 from rebounding. After the second wrapping layer 202 near the starting end is completed, the braided second wrapping layer 202 and the position of the elastic body 3 near the ending end are clamped. The first rope core 101 of the elastic body 3 is stretched to a naturally elongated state in the middle. The first wrapping layer 102 is continued to be woven on the outside of the first rope core 101. The first wrapping layer 102 is stretched and retracted with the first rope core 101. After the first wrapping layer 102 is woven, the position near the end of the first wrapping layer 102 and the end of the end are clamped and stretched to form the second rope core 201 at the other end. The two ends of the elastic body 3 with a smaller number of weaves near the end are clamped to form the second rope core 201 at the other end. The second wrapping layer 202 at the other end is continued to be woven on the outside of the second rope core 201 near the end.

[0034] Install the first protective sleeve 4 and the second protective sleeve. The first protective sleeve 4 is placed on the outside of the rope body 1, and its length is variable. The second protective sleeve is placed on the middle of the connecting rope body 2. The two ends of the first protective sleeve 4 are fixed to the two ends of the rope body 1 respectively.

[0035] To create a loop structure, fix both ends of the connecting rope 2 to form a loop structure. The fixing method can be heat pressing, adhesive, or fixing buckles.

[0036] Install the connecting sleeve 5, pull both ends of the first protective sleeve 4 to the end of the rope body 1, install the connecting sleeve 5 on the end of the first protective sleeve 4 near the connecting rope body 2 and on the outside of the connection position of the connecting rope body 2, fix both ends of the first protective sleeve 4, and effectively protect the connection position of the elastic connecting rope through the connecting sleeve 5, and further enhance the firmness of the ring structure.
