FR 3 061 211 - A1 (57) The present invention relates to a rope (1) comprising a braided tubular main sheath (3), comprising at least n braided wicks, and having an internal volume (5), and a braided tubular main core (7), comprising at least p braided wicks, housed in said interior volume (5) of the main sheath (3), n and p being whole numbers greater than or equal to 4. Said cord (1) comprising at least its first (the) end a splice (10) comprising a distal portion (12) comprising a first portion in the form of a loop (14) comprising neither a main core (7), nor an auxiliary core (20), and a proximal part (16), in the extension of the distal part (12), comprising a braided tubular auxiliary sheath (18) and a braided tubular auxiliary core (20) arranged in the interior volume (5) of the main sheath (3) and comprising a total number of braided locks m less than (n + p) locks.

The present invention relates to the field of ropes comprising at one of their ends a splice forming a loop, in particular for pruning or practicing a sport such as climbing trees, and the methods of manufacturing such splices.

Invention background

In the field of pruning, or even climbing trees, it is known to use ropes provided at one end with a loop-shaped splice, the second end being free of splices in order to present a small footprint allowing it to be passed through the various mechanical devices used, such as for example mechanical blockers, descenders, spider jack ART, such as the ZIGZAG® marketed by PETZL, the pulleys.

It is indeed not possible to pass a bulky splice in these mechanical devices.

The constructions of the strings can be varied according to the properties that one wishes to attribute to them. The realization of splices is therefore constrained by their particular construction.

Cords are thus known comprising a braided tubular sheath having elongate elements parallel to each other. The cord has at one end, a loop-shaped splice consolidated with a very voluminous seam. The loop-shaped portion does not include a core. The second end of the rope must be free because the first end including the splice cannot be passed through the usual mechanical devices. In some cases, the elongate elements of the core are braided with the end of the sheath retracted on itself in its internal volume. This manual braiding operation is nevertheless tedious, and makes it possible to reduce the size of the splice, but not to the point of being able to pass this splice through the used mechanical devices.

There are also ropes comprising a braided tubular sheath receiving in its internal volume a braided tubular core. These ropes are generally quite rigid and have little elongation compared to ropes comprising a core made up of elongated elements parallel to each other. The rope has a loop-shaped splice at one end, the loop-shaped portion is formed from the sheath and the core. The portions of the sheath and of the core returned to the interior volume of the sheath to form a loop are slightly degreased so as to remove a few strands of the sheath and of the core. The splice is blocked with a thick seam. The splice obtained is here too bulky to be able to be passed through the used mechanical devices, so that one end of the rope must be free in order to be able to pass the latter in said mechanical devices.

However, it may be advantageous for a rope to have two loop-shaped splices at each end, in order to avoid in particular passing over a whole length of rope of several meters (in particular a few tens of meters), in a blocker for example, to access the correct end.

In addition, when the splice is worn out, the rope is usually discarded. The presence of an additional splice would extend the life of the rope.

However, the reduction in volume of the splice should not be accompanied by a reduction in the mechanical performance of the latter.

Subject and summary of the invention

The present invention relates to a cord comprising, at at least one of its first and second ends, a splice, comprising a portion which forms a loop, having good mechanical strength (daN) and capable of being passed through the devices. conventional mechanics used in the technical field of pruning, in particular by climbing arborists, or even in the field of sport, such as climbing, in particular for climbing trees.

The present invention thus relates, according to a first aspect, to a cord comprising a braided tubular main sheath, comprising at least n braided wicks, and an interior volume, and a braided tubular main core, comprising at least p braided wicks, housed in said internal volume of the main sheath, n and p being whole numbers greater than or equal to 4, preferably greater than or equal to 8. Said cord comprises first and second ends, at least one of said first and second ends comprising a splice. Advantageously, said splice comprises a distal part comprising a first portion in the form of a loop and a proximal part in the extension of the distal part. The proximal part comprises a braided tubular auxiliary sheath and a braided tubular auxiliary core disposed in the interior volume of the main sheath and comprising a total number of braided wicks m less than (n + p) wicks, said first loop-shaped portion does not includes no main soul, no auxiliary soul.

Advantageously, the first portion in the form of a loop does not include a core, so that the portion in the form of a loop has a very small overall size facilitating its passage through the used mechanical devices. This arrangement is combined with a reduction in the number of wicks in the auxiliary core and the auxiliary sheath, thereby further reducing the volume of the splice.

Advantageously, the main sheath portion receiving the proximal part does not include a main core, which implies that the external diameter of the splice corresponds to the superposition of the auxiliary sheath, the auxiliary core and the main sheath.

Preferably, the auxiliary sheath and the auxiliary core comprise a total number of braided wicks m less than (n + p) wicks. Advantageously, the rope then has an external diameter at the level of the proximal part of its splice substantially equivalent to the diameter corresponding to the main sheath receiving the main core over the length of the rope, since the number of wicks in the auxiliary core and in the auxiliary sheath has been divided at least in half.

For the purposes of the present invention, the term "wick" means any elongated textile element supported by a spindle on a knitting machine. A wick can include one or more wires. The yarns can be monofilament yarns and / or yarns spun with fibers and / or monofilament yarns.

Preferably, n and p are less than or equal to 48, more preferably less than or equal to 32, more preferably n and p are between 4 and 24, even more preferably n and p are between 8 and 24.

The integers n and p can be different or identical, preferably they are identical (n = p).

Preferably, the sum of the titles (dtex) of the locks in the main sheath is greater than or equal to the sum of the titles (dtex) of the locks in the main core.

Preferably, said first loop-shaped portion is formed by said main sheath.

Preferably, the auxiliary sheath and the auxiliary core are in the extension of the main core.

The braided main tubular sheath comprises an external face and an internal face and the braided tubular main core comprises an external face and an internal face.

The external face of the main core is oriented towards the internal face of the main sheath.

In one embodiment, at least one wire is stitched over a determined length of the splice, in particular in the second portion of the distal part and possibly on the proximal part, in particular over a length of at least 10 cm, more particularly at least 15 cm, from the eye of the loop. The stitching is preferably carried out in a zig-zag pattern. This stitching makes it possible to prevent the main sheath portion arranged in itself from sliding. However, the friction generated between the main sheath portion housed in the main sheath and the internal face of the main sheath is sufficient since mechanical tests are carried out on the splice without this puncture.

In one embodiment, the cord according to the invention has an external diameter, measured outside said at least one splice, corresponding to the main sheath receiving the main core, greater than or equal to 5 mm and less than or equal to 30 mm, preferably greater than or equal to 8 mm and less than or equal to 20 mm, more preferably greater than or equal to 10 mm and less than or equal to 15 mm, in particular between 10.50 mm and 13.50 mm (upper limits and lower included).

In a variant, the proximal part comprises a first part in which the auxiliary core is arranged in the interior volume of the auxiliary sheath and a second part, in particular in the extension of the first part, in which the auxiliary sheath is arranged in the internal volume of the auxiliary core.

Preferably, the first part, and possibly the second part, a / have a length greater than or equal to 50 mm, more preferably greater than or equal to 100 mm, more preferably greater than or equal to 150 mm, in particular greater than or equal to 200 mm, in particular less than or equal to 400 mm.

In a variant, in the first part, and possibly in the second part, the auxiliary core is braided with a number of wicks which is less than or equal to 80%, preferably less than or equal to 50%, possibly less than or equal to 30%, to the number p of wicks of the main core.

In a variant, in the first part, and possibly in the second part, the auxiliary sheath is braided with a number of wicks which is less than or equal to 80%, in particular less than or equal to 50%, to the number n of wicks of the main sheath.

The last two variants make it possible to keep an external diameter for the proximal part of the same order as the external diameter of the cord.

The length of the first and second parts is important, which further improves the junction and therefore the superposition of the auxiliary core with the auxiliary sheath thus optimizing the regularity of the external diameter of the rope.

These last provisions improve the sensations and the comfort of the user of the rope when it slides in mechanical devices, such as blockers or pulleys, thus avoiding the zones of weakness and therefore the potential jolts during the scrolling of the rope in these devices.

In a variant, the distal part comprises a second portion in the extension of the first portion in the form of a loop, comprising a portion of main sheath housed in the interior volume of the main sheath.

The main sheath is thus retracted on itself to form the first portion in the form of a loop, and said second portion.

Advantageously, the splice does not include an auxiliary core, nor a main core at the second portion (or the first portion), thus limiting the external diameter of the splice.

Advantageously, the external diameter of the second portion is of the same order as the external diameter of the main sheath receiving in its internal volume the main core. Indeed, the total number of wicks of the main sheath n and of the main core p is of the order of (n + p) wicks and the number of wicks of the second portion is of the order of (n + n) wicks. This arrangement is particularly advantageous when n and p are equal.

In a variant, the length of the second portion (of the distal part) is greater than or equal to 50 mm, more preferably greater than or equal to 100 mm, more preferably greater than or equal to 150 mm, in particular greater than or equal to 200 mm.

This arrangement avoids the creation of a thick seam to block the loop since the friction between the second portion of main sheath and the main sheath blocks the sliding of the part of the splice housed in the main sheath.

A simple stitching can be carried out for safety to improve the blocking of the first portion in the form of a loop, but it is not necessary to carry out a bulky seam.

In a variant, the distal part is formed by the main sheath and does not include a main core, nor an auxiliary core.

In a variant, the wicks braided in the main and auxiliary sheaths and the main and auxiliary cores comprise one or more multifilament yarn (s) and / or one or more yarn (s) spun with fibers.

In a variant, the wicks are in one or more materials chosen from the list consisting of: low density polyethylene (LDPE); high density polyethylene (UHMWPE); polypropylene; polyamides (in particular PA 6-6, PA 4-6, PA 12, PA 11,

PA 6); polyesters, in particular polyethylene terephthalate; polyetheretherketone (PEEK); meta-aramid; para-aramid; polyazoles, such as poly (p-phenylene-2,6-benzobisoxazole) (PBO); fluoropolymers; or their mixtures.

In a variant, the wicks braided in the main and auxiliary sheaths and the main and auxiliary cores each have a titration (dtex) greater than or equal to 10,000 dtex, and less than or equal to 50,000 dtex, preferably greater than or equal to 18 000 dtex and less than or equal to 40,000 dtex, more preferably greater than or equal to 20,000 dtex and less than or equal to 35,000.

The subject of the present invention is, according to a second aspect, a method of manufacturing a rope according to any of the variant embodiments described above with reference to a first aspect, comprising the provision of a rope comprising a sheath main braided tubular having an interior volume, and a main braided tubular core housed in said interior volume of the main sheath, the main sheath comprises at least n braided wicks and the main core comprises at least p braided wicks, n and p being whole numbers greater than or equal to 4, said cord comprising first and second ends. Said method further comprises the following steps:

i) take the main core out of the main sheath through an exit point from said main sheath over a determined length L1 of said rope from one of its first and second ends so as to obtain portions of separate main and sheath core extending between said exit point and their respective first or second free ends;

ii) removing part of the braided locks from said main core portion over a determined length U7, less than the length L2 of the main core portion extended, from its first end to form an auxiliary core;

iii) remove a part of the braided locks from the main sheath portion over a determined length € 33 from its first end to form an auxiliary sheath, € 33 being less than the length L1 so as to provide a main sheath portion ( i.e. not degreased) free of main web between the point of exit and the start of the auxiliary sheath;

iv) introducing the auxiliary core into the interior volume of the auxiliary sheath according to a first part;

v) introduce the auxiliary sheath into the interior volume of the auxiliary core according to a second part, vi) slide the portion of the main core out, which is in connection with the sheath and auxiliary core then the portion of main sheath, in the internal volume of the main sheath up to forming a first portion in the form of a loop projecting from said exit point and comprising no main core or auxiliary core, said main sheath portion introduced into the main sheath forming with said first loop-shaped portion, the distal portion of a splice; and the first and second parts forming a proximal part of said splice, the proximal part being in the extension of the distal part.

The variant embodiments and definitions described with reference to a first aspect apply independently of each other to the second aspect of the invention.

Description of the drawings

The invention will be better understood on reading the following description of an embodiment of the invention given by way of nonlimiting example, with reference to the appended drawings, in which:

- Figure 1 shows schematically a first example of rope according to the invention provided with a splice at its first end;

- Figures 2 to 6 show schematically the different steps of the method for making a splice according to the invention;

- Figure 7 shows schematically the first example of rope according to the invention provided with a splice at its first end.

Detailed description of the implementation examples

The first example of rope represented in FIG. 1 comprises a braided tubular main sheath 3, comprising at least n braided wicks, and having external faces 3a and internal 3b as well as an interior volume 5. The rope 1 comprises a tubular main core braided 7, comprising at least p braided wicks, housed in the interior volume 5 of the main sheath 3.

The numbers n and p are whole numbers greater than or equal to 8 and, in a first example, are equal to 24.

The rope 1 comprises at least at one of its first la and second lb ends, a splice 10, in this specific example according to its end la. Said splice 10 comprises a distal part 12, which comprises a first loop-shaped portion 14. Said splice 10 also comprises a proximal part 16 in the extension of the distal part 12. The proximal part 16 comprises a braided tubular auxiliary sheath 18 and a braided auxiliary tubular core 20, both disposed in the interior volume 5 of the main sheath 3, and comprising a total number of braided wicks m less than (n + p) wicks, in this specific example, said total number of braided wicks m is equal to (n + p) / 2. Said first loop-shaped portion 14 does not comprise a main core 7, nor an auxiliary core 20.

As can be seen in FIG. 1, the first loop-shaped portion 14 is made up of said main sheath 3.

The proximal part 16 comprises a first part 22 in which the auxiliary core 20 is disposed in the auxiliary sheath 18 and a second part 24, in the extension of the part 22, in which the auxiliary sheath 18 is arranged in the interior volume of the auxiliary core 20.

In the first part 22 and the second part 24, the auxiliary core 20 is braided with a number of wicks equal to approximately half the number p of wicks of the main core 7 (ie of the order of p / 2 wicks ).

In the first part 22 and in the second part 24, the auxiliary sheath 18 is braided with a number of wicks equal to approximately half the number n of wicks of the main sheath, which here amounts to approximately n / 2 wicks of the main sheath 3.

The distal part 12 comprises a second portion 26 in the extension of the first loop-shaped portion 14 comprising a portion of main sheath 13 housed in the interior volume 5 of the main sheath 3.

The length L26 of the second portion 26 is, in this specific example, greater than or equal to 25 cm, in particular of the order of 30 cm.

The length L14 of the first loop-shaped portion 14 is of the order of 2.5 cm.

The distal part 12 is therefore formed by the main sheath 3 and does not include a main core 7, nor an auxiliary core 18.

The wicks braided in the main 3 and auxiliary sheaths 18 and therefore the main 7 and auxiliary 20 cores each comprise one or more twisted multifilament yarn (s), in particular one or more multifilament yarn (s) ) in polyester (polyethylene terephthalate) twisted (s) (in particular of the order of 50 to 150 turns / meter).

In said first example, the main sheath 3 thus comprises 24 wicks (therefore supported on the knitting loom by 24 spindles), each of said wicks comprises 10 threads of 1100 dtex, which represents a total of 264,000 dtex.

The auxiliary core thus comprises 24 wicks, each of said wicks comprises 7 wires of 1100 dtex, which represents a total of 184 800 dtex.

The number of wires and their titration depends on the diameter and the toughness that one wishes to assign to the cord 1.

The rope 1 shown in Figure 1 advantageously comprises a splice 10 having a very small footprint, which allows it to be passed, and to slide, on the used mechanical devices, especially in the field of pruning or climbs trees.

The external diameter DI of the cord 1 at the main sheath 3 receiving the main core 7 is between 10.5 mm and 13.5 mm (upper and lower terminals included), in this specific example of the order of 12 mm. The external diameters D22, D24 respectively of the first part 22 and of the second part 24 are advantageously of the same order and in particular of the order of the diameter Dl.

The advantageous construction of the splice 10 makes it possible to obtain a substantially regular diameter from the second portion 26 and over the entire length of the cord 1, which improves the regularity of the cord 1 and the sensations obtained with the latter when 'it scrolls through a mechanical device such as a blocker, for example. There are no jerks in particular.

In addition, the second portion 26 has a length L26 of the order of 30 cm, which allows friction to be obtained between the main sheath portion 13 housed in the interior volume 5 of said main sheath 3 and the internal face 3b. of the main sheath 3 itself, the friction generated facilitates the holding in place of the splice 10.

A topstitch extending from the exit point 30 of the first loop-shaped portion 14 over a length of approximately 15 to 20 cm, in particular in a polyester thread, can be carried out for safety but it is not essential .

A second splice, structurally equivalent to the splice 10, can be made at the second end 1b of the cord 1. This arrangement improves the life of the cord 1 since the two ends 1a and 1b are used.

FIGS. 2 to 7 illustrate, schematically, the different steps enabling the splicing 10 of the cord 1 shown in FIG. 1 to be carried out.

FIG. 2 represents a cord 1 in which, first of all, the main core 7 has come out of the main sheath 3 through an exit point 30 of the main sheath 3 over a determined length L1 from its first end it so as to obtain main core portions 77 of length L2 and main sheath 33 of length L1, separated and extending between said outlet point 30 and their first 33a, 77a respective free ends. In this specific example, L1 and L2 are equal to about 75 cm.

Marks a1 and a2, and b1 and b2 are reported, for example using a felt pen, at a distance of approximately 20 cm for the marks al and a2, and at a distance of approximately 40 cm for the marks bl and b2, respective first ends 33a and 77a.

Then, a portion of the braided locks of the main output core portion 77 is removed over the length t77 to form an auxiliary core 20.

The length t77 is less than the length L2 of the main output core portion 77, and is measured from its first end 77a.

The proportion of braided locks removed from the main core portion 77 is approximately 50% of the number p of braided locks. Thus, approximately p / 2 braided locks are removed so as to form the auxiliary core 20.

Similarly, a part of the braided locks of the main sheath portion of the outlet 33 is removed over the length t33 to form an auxiliary sheath 18. The length t33 is less than the length L1 of the main sheath portion of the outlet 33, and is measured from its first end 33a.

The proportion of braided locks removed from the main sheath portion leaving 33 is approximately 50% of the number n of braided locks. Thus, approximately n / 2 braided locks are removed so as to form the auxiliary sheath 18.

The auxiliary core 20 is then introduced using the hollow needle 40 into the interior volume of the auxiliary sheath 18 along a first portion 22 by inserting said auxiliary core 20 around the point a 1 and coming out after the point b 1 represented in FIG. 2. The rope 1 then appears as shown in FIG. 3.

The auxiliary sheath 18 is then inserted as shown in FIGS. 4 and 5 using the hollow needle 40 in a second part 24 by returning the needle 40 supporting the auxiliary sheath 18 around the point a2 and in emerging around the point b2.

Is obtained, as shown in Figure 6, the first 22 and second 24 parts in which the auxiliary core 20 and the auxiliary sheath 18 are returned to each other in turn. Then, the outlet core portion 77 which is connected to the auxiliary sheath 18 and the auxiliary core 20 is made to slide in the interior volume 5 of the main sheath 3 until a first loop-shaped portion 14 is formed. projecting from said exit point 30 and not comprising a main core 7 or an auxiliary core 20.

Said first portion in the form of a loop 14 therefore consists only of the main sheath 3. Said portion of main sheath

13, introduced into the interior volume 5 of the main sheath 3, forms the second portion 26 of the splice 10. The second portion 26 and the first loop-shaped portion 14 form the distal portion 12 of the splice

10. The first 22 and second 24 parts introduced into the main sheath 3 form, for their part, a proximal part 16 of the splice 10, the proximal part 16 being in the extension of the distal part

14.

The cord 1 obtained has a substantially regular diameter DI over its entire length and in particular over the length of the splice 10 extending over the lengths (26, 122 and (24 of the order of 70 cm inside the sheath) main tubular 3.

Rope 1 meets the criteria set out in standard EN 1891 dating from 1998 in that, under the application of a force of 1,500 daN for 3 min, no break is observed. Said rope 1 also satisfies the performance criterion of carrying out five falls of factor 1 without breaking, as defined in the aforementioned standard.

Due to the small size of the splice 10, the rope 1 may have a splice at each of its ends, which prolongs the life of the rope and facilitates its use.

In addition, due to the construction of the splice 10, the cord 1 has substantially around 24 braided locks over its entire length, which contributes to its homogeneity and to the good feelings of the user during its unwinding in the mechanical devices. employees.

The rope 1 can be used in applications for high-rise works, in the arboreal field (for example in the field of pruning by climbing arborists), or in the field of sport and in particular in the field of climbs trees.
