  • the braided structure includes a plurality of uninterrupted or continuous strands extending between the opposite ends of the structure and braided into a first portion or segment (e.g., a body) with one braid pattern and a second portion or segment (e.g., a plurality of legs) with a second braid pattern.
  • a braided rope structure is formed from a plurality of continuous strands or ends. Each strand may be wound around a carrier (not shown), and the plurality of (twisted) strands are braided together in order to form a braid unit or segment 10.
  • each braid segment 10 includes a rope body 14 and a plurality of legs 18 extending from the rope body 14. In the illustrated embodiment, four legs 18 extend from the body 14 and are arranged generally in an X-shape. The continuous strands extend continuously through the body 14, with one braid pattern, and the legs 18 with another braid pattern (or patterns).
  • Each braid segment 10 has opposite ends 22, 24.
  • a first leg l8a and a second leg 18b are positioned adjacent the first end 22, and a third leg l8c and a fourth leg 18d are positioned adjacent the second end 24.
  • the braid segment 10 forms a continuous braid between the ends 22, 24.
  • each strand extends continuously from the first end 22 to the second end 24 such that the braid segment 10 is formed as a continuous structure.
  • the braided unit 10 is symmetrical.
  • the strands are initially braided into the first leg l8a and the second leg 18b, each leg l8a, 18b including a number of strands (the same number in each, as illustrated) and having a braid pattern (the same for each, as illustrated).
  • the braid pattern of the braided unit 10 changes after a given length from the pattern of the leg(s) l8a, 18b so that all of the stands of the first and second legs l8a, 18b are braided together to form the body 14 with another braid pattern.
  • Changing of the braid pattern is done in a continuous process so that the strands are continuously braided and do not need to be spliced.
  • the braiding pattern changes again so that the strands of the body 14 furcate into the third leg l8c and the fourth leg 18d at a furcation point 30, each leg l8c, 18d including a number of strands (the same number in each, as illustrated) and having a braid pattern (the same for each, as illustrated).
  • the braid pattern changes so that strands that form the body 14 are braided into two distinct legs l8c, 18d.
  • a braid segment 10 may be formed into a braided rope structure, such as a double-eyed basket sling lOa.
  • the sling lOa is formed from a twenty-four carrier braid.
  • twenty-four strands are utilized in braiding the sling lOa with the body 14 consisting of twenty-four strands and each leg l8a-l8d consisting of twelve strands.
  • legs l8a-l8d may include an unequal number of strands (e.g., the sling lOa could furcate into legs 18 with eight and sixteen strands respectively).
  • the first and second legs l8a, 18b are spliced together at a first connection point 34.
  • the third and fourth legs l8c, 18d are spliced together at a second connection point 38.

  • the connection points 34, 38 are formed after the braid segment 10 is complete.
  • the body 14 has an elongated length Li, and each of the legs 18 have an elongated length L 2 (FIG. 1).
  • the length Li of the body 14 is a significant portion of a total length L of the braid segment 10 (e.g., the length Li is at least one-third the total length L).
  • a larger length Li provides a greater surface area to support a mass.
  • the body 14 may have a rectangular or flattened cross-section compared to a rounded cross-section of the legs 18. As more strands are utilized in a braid pattern, the braid can begin to flatten out. A flattening threshold may be between sixteen and twenty strands. Accordingly, a twelve strand braid, as utilized in the legs 18, may not include enough strands to produce the flattened cross-section, but a twenty-four strand braid, as utilized in the body 14, may produce a flattened cross-section.
  • the illustrated flattened cross-section may provide better bending performance than a rounded cross section. In other words, it is easier to bend a braided structure with a flattened cross section than with a rounded cross section.
  • the body 14 may include more than a twenty-four strand braid (e.g., a thirty-two strand braid, a seventy-two strand braid, etc.). Adding additional strands increases a density and a diameter of the body 14. Adding additional strands above the flattening threshold increases the likelihood of producing a flattened cross-section.
  • a twenty-four strand braid e.g., a thirty-two strand braid, a seventy-two strand braid, etc.
  • different braid angles may be used along different segments of the sling lOa.
  • higher braid angles facilitate splicing and may be incorporated into the legs 18 to, therefore, facilitate the formation of the loops 42.
  • Lower braid angles may provide improved tensile performance and may, therefore, be utilized along the body 14.
  • a lower braid angle would assist the body 14 in supporting and bending as a result of the force of a supported load.
  • the loops 42 may be configured to be placed over hooks (not shown) and a load (not shown) may supported by the body 14.
  • the flattened cross-section of the body 14 may allow the sling lOa to bend while supporting the load.
  • the body 14 may form a U-shaped segment which may be used to seat the load.
  • the lower braid angle of the body 14 allows the sling lOa to support the force of the load on the U-shaped segment.
  • braided rope structure may be formed in a chain-line manner consisting of braid segments 10 formed end-to-end over the length of the braided rope structure.
  • a plurality of braid segments 10 form a second braided rope structure, such as a chain lOb.
  • the braid segments 10 are braided together as a continuous braid over the length of the chain lOb.
  • the third and fourth legs l8c, 18d of one braid segment 10 provide the first and second legs l8a, 18b of a subsequent braid segment 10 and are furcated to form the body 14 of the subsequent braid segment 10.
  • the chain lOb is braided from a first end 46 to a second end 50.
  • the first end 46 includes a first braid segment 10 with free first and second legs 54, 58.
  • the second end 50 includes a last braid segment 10 with free third and fourth legs 62, 66.
  • the first and last braid segments 10 in the chain lOb are not braided to additional braid segments 10 on both sides of these braid segments 10.
  • first and second legs 54, 58 of the first braid segment 10 and the third and fourth legs 62, 66 of the last braid segment 10 are therefore not connected to any other leg 18 after the braid pattern is concluded.

  • the chain lOb extends a length L 3 , and along the length L 3 is a plurality of interlocking braids or bodies 14, each between the convergence and furcation points 26, 30.
  • Two legs l8a, 18b bifurcate from the interlocking braid l4a, and two legs l8c, 18d converge or refurcate into the interlocking braid l4b.
  • Each interlocking braid 14 is formed as a continuous braid so that the total number of strands in the chain lOb is braided together into the interlocking braid 14. In other words, each interlocking braid 14 is formed of the total number of strands in the associated legs 18.
  • each interlocking braid 14 has a length and a thickness, both of which are significantly less than the length L 3 of the chain lOb.
  • the length of an interlocking braid 14 is greater than its thickness.
  • the length of the interlocking braid 14 may be at least about twice and up to about six times (or more) its thickness.
  • the length of the interlocking braid 14 is at least about four times its thickness. In other words, the thickness of all strands braided together in the interlocking braid 14 is about one quarter its length.
  • Eyes or loops 42 are formed along the length of the chain lOb.
  • a loop 42 can be defined by the two adjacent interlocking braids 14 and the legs 18.
  • loops 42 proximate an end of the chain lOb may be defined when the free legs 54, 58, 62, 66 of the first or last braid segments 10 are spliced together.
  • each loop 42 has substantially the same size.
  • the interlocking braids 14 may have a rectangular or flattened cross-section compared to the rounded cross-section of the legs 18.
  • the braid may begin to flatten out, and a flattened cross-section may provide better bending performance than a rounded cross section.
  • different braid angles may be used along different segments of the chain lOb.
  • a tensile force may be applied longitudinally from either end of the chain lOb or laterally to opposite sides of a loop 42.
  • the length-to-thickness ratio of the interlocking braids 14 provides the chain lOb with increased strength necessary to withstand such forces applied to the chain lOb.
  • Each interlocking braid 14 is capable of withstanding the applied force, so that the interlocking braid 14 does not unravel.
  • the low braid angle in the interlocking braid 14 also helps to support the tensile load.
  • Synthetic strands used to braid the chain lOb are lighter than metal, which may make the chain lOb lighter than a traditional metal link chain (not shown). Synthetic materials are corrosion resistant, which may provide another advantage the chain lOb compared to a metal link chain.
  • a plurality of braid segments 10 may form a third braided rope structure, such as a soft shackle lOc.
  • the braid segments 10 are braided together as a continuous braid over the length of the shackle lOc.
  • the third and fourth legs l8c, 18d of one braid segment 10 are the first and second legs l8a, 18b of a subsequent braid segment 10.

  • the interlocking braid or body 14 may include an elongated length.
  • the interlocking braid 14 of the soft shackle lOc is longer than the interlocking braid l4a or l4b of the chain lOb (FIG. 3B).
  • the interlocking braids 14 of the shackle lOc may have different lengths in order to, for example, provide more or fewer or differently-spaced loops 42 along its length.
  • the knots 74, 76 may be positioned with the loops 42 in order form secondary loops 80 to define a working configuration.
  • the knots 74, 76 may be positioned within any of the loops 42 along the length of the shackle lOc in order to adjust a working length of the shackle lOc.
  • a shackle lOc with shorter interlocking braids l4c includes more loops 42, and the increased number of loops 42 allows a user to make more finite length adjustments to the shackle lOc.
  • a tensile force may be applied longitudinally from either end of the shackle lOc or laterally to opposite sides of a loop 42.
  • the length-to-thickness ratio of the interlocking braids 14 provides the shackle lOc with increased strength necessary to withstand such forces applied to the shackle lOc.
  • Each interlocking braid 14 is capable of withstanding the applied force, so that the interlocking braid 14 does not unravel.
  • the low braid angle in the interlocking braid 14 also helps to support the tensile load.
  • axial members 84 may be included as part of the braid patterns.

  • a braid body 104 bifurcates into a first leg l8a and a second leg 18b.
  • the sling 92 may include more than thirty-two strands (e.g., seventy-two strands). Increasing the number of strands in the sling 92 increases the number of potential legs 18 or the combinations of strands per leg 18.
  • the furcations in the sling 92 are not symmetrical as in the previous braided rope structure lOa, lOb, or lOc.

  • the braid may continue to bifurcate until the resulting odd and even numbered legs 18 have the same number of strands. Once the legs 18 have an equivalent number of strands (or at another point), the process is reversed, and the legs 18 are refurcated in the reverse order in which they were bifurcated (FIG. 10). This process continues along the length L 4 of the sling 92 until the last legs (i.e., l8a, 18b) have been refurcated.

  • the core 84b has a greater strength than a rope body 132 and is, therefore, capable of supporting a greater force than the rope body 132.
  • a core 84b may extend through the legs 18 (FIG. 6B). This provides each leg 18 with the strength of the core 84b plus the number of braided strands in that leg 18, which enables the leg 18 to support a greater force.
  • the sling 92 may be formed from a continuous run between the first end 124 and the second end 128. In other words, the sling 92 may be formed from a continuous, interwoven braid.
  • the interwoven strands can provide different characteristics or properties to different parts of the sling 92 depending on the number of strands in the legs 18.
  • a user may cut the sling 92 along a middle axis F orthogonal an axis E.
  • the middle axis F intersects the sling 92 after the last bifurcation but before the first refurcation.
  • the cut forms two substantially identical slings 92, where there are no refurcation points.
  • the ends of all of the legs 18 would have the same number of strands. In other words, new legs 18 are furcated from a previous leg 18, as described above, but the legs 18 are not furcated back together.

  • the braided net 136 is formed from a series of net segments or tandem braided bifurcations 144.
  • the tandem braided bifurcations 144 begin with four free legs l48a-l48d, which each contain eight strands; although in other embodiments, different numbers of free legs l48a-l48d and/or stands per leg may be used.
  • each of the free legs l48a-l48d bifurcate into two legs at a furcation point 150.
  • two of the free legs l48a, l48d e.g., the outermost free legs 148) bifurcate into a first or outer leg 152 and a second or inner leg 156.
  • the other two free legs l48b, l48c e.g., the inner free legs 148) bifurcate into two inner legs 156.
  • both the outer and inner legs 152, 156 have the same number of strands (e.g., four strands); although in other embodiments, the outer legs 152 may have a different number of stands than the inner legs 156.
  • the inner strands 156 converge to form interlocking braid bodies 14 at convergence/furcation points 140.
  • the tandem braided bifurcations 144 includes three convergence/furcation points 140.
  • An inner stand 156 that originated from one free leg 148 forms an interlocking braid body 14 with an inner strand 156 that originated from an adjacent free leg 148 (e.g., an inner leg 156 that originated from the second free leg l48b converges with the adjacent inner leg 156 that originated from the third free leg l48c).
  • Inner legs 156 furcate from the body 14, and there are again eight total legs 152, 156.
  • the each leg 152, 156 has an equal number of stands after the convergence/furcation points 140.
  • the outer legs 152 extend unimpeded. A given length after the convergence/furcation points 140, the legs 152, 156 that originated from the same free leg l48a-l48d converge at second convergence/furcation points 160 (e.g., the outer leg 152 and the inner leg 156 that originally furcated from the first free leg l48a converge at a second convergence/furcation point 160).
  • the tandem braided bifurcations 144 immediately repeat, and outer and inner legs 152, 156 furcate from the second convergence/furcation points 160.
  • first and second convergence/furcation points 140, 160 i.e., inner legs 152 converge and furcate, followed by the convergence and furcation of the legs 152, 156 that originated from the same free leg l48a-l48d
  • first and second convergence/furcation points 140, 160 may continue as many times as required. Repetition of this pattern forms eyes 42, which makes up the structure of the braided net 136.
  • legs l64a-l64d separate each of the tandem braided bifurcations 144.
  • each of the legs l64a-l64d has the same number of strands as the free legs l48a-l48d (e.g., eight strands).
  • the legs l64a-l64d create second eyes 168, which are larger than the eyes 42.
  • the lengths of the legs l64a-l64d may be larger or smaller in order to adjust the size of the second eyes 168, for various user applications.

Abstract

L'invention porte sur une structure de corde tressée comprenant un premier segment et un second segment. Le premier segment a une première extrémité et une deuxième extrémité opposée à la première. Le premier segment comprend des premiers brins tressés en un premier motif de tresse. Le second segment a une troisième extrémité couplée à la deuxième extrémité. Dans le second segment, les premiers brins sont tressés en un second motif de tresse différent du premier motif de tresse. Les premiers brins s'étendent de façon continue le long du premier segment et du second segment.
