Description

Title of the invention: QUICKBITE CONNECTOR, QUICKBITE AND MANUFACTURING METHOD technical field

[0001] The invention relates to a quickdraw connector, a quickdraw and a method for manufacturing such a quickdraw connector. State of the art

[0002] In mountaineering and other mountain activities, it is common to use quickdraws that attach to an anchor point and are designed to receive a rope. The quickdraw has two carabiners that are connected by a flexible connector.

[0003] The flexible connector defines two distinct rings separated by a predefined distance. Each of the two rings receives a carabiner, but it is possible to install another type of anchoring element as needed.

[0004] Conventionally, the connector is formed by a strap that is folded several times to define two opposing loops along the longitudinal direction of the connector. The multiple layers of strap are attached to each other by stitching. Such an instruction is illustrated in documents USD747176 and US20180001144.

[0005] A substantially equivalent teaching is contained in US patent 8,973,509, which proposes using a tubular woven material that is folded around its hollow central portion to form a hollow ring. The ring is deformed to define two opposing loops separated by an intermediate portion where two layers of the folded woven material are brought into contact and secured by sewing.

[0006] US patent 2015 / 0352407 proposes an alternative ring configuration in which a wire is wound into a coil. The multiple turns of the coil are enclosed in a strip of textile material, which is folded lengthwise and sewn to form a tube around the coil. The two ends of the tube are joined together to enclose the coil within a sheath formed by the strip of textile material. The tubular woven material no longer defines the mechanical performance of the ring; this performance is primarily defined by the multiple loops installed inside the ring. Description of the invention

[0007] An object of the invention is to provide a quickdraw connector which offers a better compromise between compactness, flexibility and tensile strength than prior art configurations.

[0008] This result is tended to be achieved by means of a sheath connector comprising: - a winding of a wire element comprising first turns of said wire element, the winding being divided into a first strand and a second strand arranged consecutively along a longitudinal direction of the wire element; - at least one first tubular element surrounding said first turns to form at least one first sheath around the winding, said at least one first tubular element being traversed by the first turns and extending along a longitudinal direction of the wire element.

[0009] The sheath connector is remarkable in that an additional tubular element is arranged around the winding to form an additional sheath; in that the additional tubular element surrounds the assembly formed by the first strand and the second strand arranged adjacently in a direction perpendicular to the longitudinal direction; in that the winding escapes from each of the two opposite ends of the additional tubular element to define a first ring with a first through hole intended to receive a first carabiner and a second ring with a second through hole intended to receive a second carabiner, the second ring being separated from the first ring by the additional tubular element; and in that said at least one first tubular element continuously surrounds the winding along the first ring and the second ring to define a first ring sheath and a second ring sheath, each end of the first ring sheath and the second ring sheath being in contact with the additional tubular element.

[0010] According to one aspect of the invention, the at least one first tubular element partially covers the first turns of the winding in the longitudinal direction of the wire element, a portion of the winding not covered by the at least one first tubular element being disposed between the sheath of the first ring and the sheath of the second ring and covered by the additional tubular element.

[0011] Preferably, the at least one first tubular element is discontinuous so that the first ring sheath and the second ring sheath are separated by an uncovered portion of the winding along the first strand and an uncovered portion along the second strand, the portions of the winding not covered by the at least one first sheath being covered by the additional tubular element.

[0012] Advantageously, at least one first tubular element is fixed to the additional tubular element by seams.

[0013] In a particular embodiment, the first strand and the second strand are each devoid of coverage by at least a first sheath between the seams along the first strand and the second strand.

[0014] Preferably, the at least one first tubular element extends continuously from the first ring to the second ring. The at least one first tubular element has a first entanglement pattern forming the sheath of the first ring which is different from a second entanglement pattern disposed between the winding and the additional tubular element.

[0015] Advantageously, the first turns of the wire element of the winding are devoid of a knot between the two ends of the wire element to form a closed ring.

[0016] The invention also relates to a quickdraw which presents a better compromise between compactness, flexibility and tensile strength between the two carabiners than prior art configurations.

[0017] This result is likely to be solved by means of a quickdraw comprising a quickdraw connector according to any of the previous configurations, a first carabiner installed in the first ring and a second carabiner installed in the second ring.

[0018] The invention also relates to a method for manufacturing a quickdraw connector which is simple to implement and which makes it possible to form a quickdraw connector with a better compromise between compactness, flexibility and tensile strength than prior art configurations.

[0019] This result is to be achieved by means of a method for manufacturing a sheath connector comprising the following steps: - provide a wire element, at least a first tubular element and an additional tubular element; - wind the wire element to form first turns of said wire element, the wire element passing through a central portion of at least one first tubular element at each turn so that said at least one first tubular element forms at least one first sheath around the first turns of the wire element; - install the wire element winding in the additional tubular element, the winding escaping from each end of the additional tubular element to define a first ring intended to receive a first carabiner and a second ring intended to receive a second carabiner, the second ring being separated from the first ring by the additional tubular element; in which said at least a first tubular element surrounds the first turns from the additional tubular element to the additional tubular element along the first ring and the second ring.

[0020] Advantageously, the at least first tubular element comprises a first main tubular element and a first secondary tubular element distinct from the first main tubular element. During the winding of the wire element to form In the first few turns, the wire element passes through the first main tubular element and the first secondary tubular element. The first main tubular element covers the first turns along the first ring, and the first secondary tubular element covers the first turns along the second ring.

[0021] Preferably, the at least first tubular element comprises a first main tubular element and a first secondary tubular element connected to the first main tubular element by a breakable portion. After winding the wire element to form the first turns, the first main tubular element is separated from the first secondary tubular element. The first main tubular element covers the first turns along the first ring, and the first secondary tubular element covers the first turns along the second ring. Description of the drawings

[0029] Figures 1 to 5 illustrate different embodiments of a quickdraw connector. The quickdraw connector has a wire element 1 which is wound to form a coil with initial turns of wire element 1. The turns of wire element 1 are in the form of loops arranged one on top of the other to form a ring. For example, the coil has at least 10 turns or at least 20 turns. The wire element 1 can be a rope, a webbing, a braid, a continuous fiber, or any other suitable wire or fiber. For example, the wire element 1 is a wire made of Dyneema®.

[0030] The wire element 1 extends continuously to define the multiple loops. The winding formed by the multiple loops can be divided into a first strand and a second strand. For example, the winding is divided into two halves, each half representing one strand of the winding. Depending on the embodiment, the first and second strands have the same number of wire elements or a difference that represents one turn of a wire element.

[0031] The cable sheath connector has at least one first tubular element 2 that surrounds only the first few turns. This at least one first tubular element 2 extends along the longitudinal direction of the wire element 1 to form at least one first sheath around the first few turns of the wire element 1. In other words, this at least one first tubular element 2 follows the shape of the ring or a portion of the ring. Depending on the embodiment, this at least one first sheath covers the entire winding or only a portion of the winding along the longitudinal direction of the wire element 1.

[0032] The at least first sheath has the first turns only once, that is to say, the first sheath follows the shape of the winding and / or the part of the winding it covers. The at least first sheath is not arranged to receive together the first strand 3 and the second strand 4 arranged adjacent and perpendicular to the longitudinal direction of the wire element 1, that is to say, a volume corresponding to a doubling of the wire elements 1.

[0033] At least one first tubular element 2 is intended to form a sheath around the multiple loops of the wire element 1 taken as a whole. At least one first tubular element 2 protects the wire element 1 from external damage.

[0034] By tubular element 2, we preferably mean an element that is intrinsically tubular, that is to say, without any gluing, sewing, or welding operation. or other. The first tubular element 2 is preferably chosen from a tubular webbing, that is to say a woven tubular element, or it may be a tubular braid or even a tubular knit. The use of an inherently tubular element allows for a better compromise between compactness and flexibility.

[0035] It is particularly advantageous that the internal volume of at least one first tubular element 2 be mostly filled by the multiple turns of the wire element. Preferably, the volume occupied by the wire element 1 represents at least 50% of the internal volume of at least one first tubular element 2, more preferably at least 70%, and even more preferably at least 80%. The larger the volume of the wire element 1 within at least one first tubular element 2, the more the different loops of the wire element 1 are forced to rub against each other, which helps to maintain the mechanical strength of the ring formed by the loops of the wire element 1 when a tensile force is applied. The tensile strength is provided by the turns of the wire element 1 and not by at least one first tubular element 2.

[0036] In addition to at least one first tubular element 2, the sheath connector includes an additional tubular element 5 that forms an additional sheath. The additional tubular element 5 is preferably an intrinsically tubular element, that is, without any sewing, welding, gluing, or other process. Preferably, the additional tubular element 5 should be chosen from a tubular webbing, that is, a woven tubular element, or it may be a tubular braid. It is also possible for the additional tubular element 5 to be a tubular knit. The choice of the additional tubular element 5 is independent of the at least one first tubular element 2.

[0037] The two strands of the winding pass through the additional tubular element 5. The winding exits at each of the two ends of the additional tubular element 5 so that the winding in wire element 1 associated with the additional tubular element 5 defines a first ring 6 and a second ring 7. The two rings are separated by the additional tubular element 5. The first ring 6 defines a first through hole intended to receive a first carabiner, and the second ring 7 defines a second through hole intended to receive a second carabiner. The two carabiners are separated by the additional tubular element 5.

[0038] At least one first tubular element 2 surrounds the wire element winding 1 along the first ring 6 and along the second ring 7 outside the area covered by the additional sheath. At least one first sheath extends continuously along the first ring 6 to form a first-ring sheath and extends continuously along the second ring 7 to form a second-ring sheath. ring. Each of the two ends of the first ring sheath and the second ring sheath is in contact with the additional sheath to protect the winding.

[0039] It is particularly advantageous to attach the ends of the first ring sheath to one end of the additional tubular element 5 by means of a fastener 8. The fastener 8 is preferably a seam. It is particularly advantageous to attach the ends of the second ring sheath to another end of the additional tubular element 5.

[0040] It is advantageous that the additional tubular element 5 is only fixed to at least one first tubular element 2 at the ends which define the sheath of the first ring and the sheath of the second ring, which allows greater mobility of the turns of the winding of the wire element 1 in the possible overlap zone between the additional tubular element 5 and at least one first tubular element 2. This allows for increased flexibility.

[0041] To gain flexibility and / or compactness, it is particularly advantageous that the at least one first tubular element 2 does not cover the entire winding in the longitudinal direction. It is then possible to define a zone of the winding that is covered by the at least one first tubular element 2 and a zone that is not covered by the at least one first tubular element 2, that is to say, a zone that is directly opposite the additional tubular element 5.

[0042] Figure 2A illustrates an embodiment where at least one first tubular element 2 extends continuously along the winding so as to cover the entire length of the winding or almost the entire length of the winding. Inside the internal volume of the additional tubular element 5 are the first strand 3 and the second strand 4 of the winding, as well as at least a portion of the at least one first tubular element 2 that surrounds the winding around the first strand 3 and the first strand 4. It is then necessary to choose an additional tubular element 5 with a large diameter to accommodate all these elements, as illustrated in Figure 2B. The larger the diameter, the larger the bulk of the cable connector. The smaller the diameter, the more the turns of the wire element 1 are compressed, which limits flexibility and complicates the manufacture of the cable connector.

[0043] Figures 3A and 4A illustrate an embodiment in which at least one first sheath 2 extends only partially along the winding so as to cover the entire length of the winding of the first strand 3 and each of the protruding portions of the winding of the additional tubular element 5 intended to form the first ring 6 and the second ring 7. The remainder of the second strand 4 is not covered. Inside the internal volume of the additional tubular element 5 are found the first strand 3 and the second strand 4 of the winding as well as part 2a of at least one first tubular element 2 which covers the first strand 3 and the ends of the first ring sheath and second ring sheath. It is then possible to choose a smaller additional tubular element 5 to accommodate all these elements because part of the first tubular element 2 has been eliminated compared to the previous embodiment. Advantageously, there is only one first tubular element that extends continuously to form the first ring sheath and the second ring sheath.

[0044] Figure IA illustrates an embodiment in which at least one first tubular element 2 covers the first turns of wire element 1 along the first ring 5 to form the sheath of the first ring and covers the first turns of wire element 1 along the second ring 7 to form the sheath of the second ring. The two portions intended to form the sheath of the first ring and the sheath of the second ring are distinct and spaced apart. The first tubular element 2 has two distinct parts, with a first main tubular element 2' and a first secondary tubular element 2" distinct from the first main tubular element 2'. The first main tubular element 2' is separated from the first secondary tubular element 2" by two uncovered areas extending respectively along the first strand 3 and the second strand 4.Between the first ring 6 and the second ring 7, the winding is devoid of a first tubular element 2 continuously covering the first strand 3 and continuously the second strand 4.

[0045] It is particularly advantageous that the first main tubular element 2' and the first secondary tubular element extend to the fasteners 8 that secure the first tubular element 5 to the additional tubular element 5. It is advantageous that the first tubular element 2 does not extend beyond the fasteners 8 in the direction connecting the first main tubular element 2' and the first secondary tubular element. By "does not extend beyond the fasteners 8," it is meant that the first tubular element 2 does not extend too far from the fasteners. The first tubular element 2 extends sufficiently beyond the fasteners 8 to prevent damage to the fastener 8. The same advantageously applies to the additional tubular element 5 in the opposite direction.

[0046] Within the internal volume of the additional tubular element 5 are found the first strand 3 and the second strand 4 of the winding, as well as the ends of the first ring sheath and the second ring sheath. Since the winding is practically devoid of a first tubular element 2 beneath the additional tubular element 5, it is possible to choose an additional tubular element 5 with a smaller diameter to accommodate all these elements. The less deeply the first tubular element 2 extends inside the additional tubular element 5 along the first strand 3 and the second strand 4, the more easily a smaller diameter additional tubular element 5 can be chosen. Reducing the diameter of the tubular element The additional 5 allows for improved compactness and the absence of a first tubular element allows for greater freedom of movement of the turns of wire element 1, which improves flexibility.

[0047] It is particularly advantageous that the turns of wire element 1 represent at least 50% of the internal volume of the additional tubular element, more preferably at least 70% or even at least 80%.

[0048] In an alternative embodiment where, in addition and as illustrated in Figure 4A, it is desired to have a single first tubular element 2 which extends along the first strand 3 and along the second strand 4 and inside the additional tubular element 5. In order to be able to reduce the diameter of the additional tubular element 5, the at least one first tubular element 2 has a smaller volume per winding length compared to what is illustrated in [Fig.2].

[0049] It is advantageous to provide that the first tubular element 2 has an entanglement pattern between the wires and / or fibers that form the additional tubular element 5, which varies according to the longitudinal direction of the additional tubular element 5, corresponding to the longitudinal direction of the winding. The first tubular element 2 has a first entanglement pattern that differs from a second entanglement pattern. The first entanglement pattern is intended to form the sheath of the first ring and / or the sheath of the second ring. The second entanglement pattern is intended to be located inside the additional tubular element 5. The second entanglement pattern has a smaller volume than the first entanglement pattern for a given length. The bulk corresponds to the volume of wires or fibers used per given length of the first tubular element 2.A differentiation of the interlocking pattern can be a differentiation of the weaving pattern, a differentiation of the braiding pattern, a differentiation of the knitting pattern, a change in the number of yarns used, or the cross-section of the yarns used.

[0050] For example, it is advantageous to keep a mechanical link between the portion of the first tubular element 2 intended to form the sheath of the first ring and the portion of the first tubular element 2 intended to form the sheath of the second ring in order to better control the positions of the different portions of the first tubular element 2 during the manufacture of the sheath connector.

[0051] Figure 4 illustrates an embodiment in which the first tubular element 2 has a first portion 2a having a first interlocking pattern and a second portion 2b having a second interlocking pattern. The first pattern 2a is intended to form the sheath of the first ring and / or the sheath of the second ring. The second pattern 2b is intended to be located inside the additional tubular element 5.

[0052] In the embodiment illustrated in [Fig. 5], the first tubular element 2 has a portion for forming the sheath of the first ring, a portion for forming the sheath of the second ring, and an additional portion for forming the mechanical link between the sheath of the first ring and the sheath of the second ring. The additional portion can define a breakable link that easily breaks during the manufacture of the sheath connector. This allows for a single first tubular element 2 that splits into two. This single tubular element is preferable during a winding step where the wire element passes through the center of the first tubular element 2 to form the winding. Once the winding is formed, the two parts of the first tubular element 2 can be separated.The breakable portion may be formed by a different interlocking pattern from the interlocking patterns intended to form the first ring sheath and the second ring sheath, or it may be the same interlocking pattern which is weakened by an additional technological operation, for example laser or manual cutting, the application of an acid, a base or a solvent, or the application of electromagnetic radiation.

[0053] The winding length is measured along the longitudinal direction of the wire element 1. If the winding is in the form of a circle, the winding length corresponds to the perimeter of the circle.

[0054] Preferably, each end of at least one first tubular element 2 has a portion covered by the additional tubular element 5 to avoid having the wire element 1 exposed.

[0055] The wire element 1 extends continuously from one end of the quickdraw connector to the other, defining the first ring 6 and the second ring 7. It ensures mechanical continuity between the two rings when the quickdraw connector is subjected to tensile stress. The mechanical continuity provided by the winding of the wire element 1 comprises several turns that are movable relative to each other, thus facilitating the creation of a quickdraw connector with a better compromise between its weight, flexibility, and compactness.

[0056] At least one first tubular element 2 and the additional tubular element 5 surround the wire element winding 1, which limits the movement of the individual turns relative to each other. This allows the wire element winding to provide the expected tensile mechanical performance while allowing good flexibility in other directions. Advantageously, the additional tubular element is at least 30% filled. The filling is observed along a cross-sectional plane that is perpendicular to the longitudinal direction of the first strand 3 and the longitudinal direction of the second strand 4. Where applicable, the turns of wire element 1 represent at least 30% of the first tubular element in the first tubular element sheath ring, in the sheath of the second ring and more preferably in each position of the first tubular element 2.

[0057] This embodiment is particularly advantageous compared to a strap because it allows a better compromise between tensile strength along the longitudinal direction and flexibility in other directions for a given compactness.

[0058] The quickdraw connector can be manufactured as follows. The manufacturing process for a quickdraw connector includes a step of supplying a wire element 1, at least one first tubular element 2, and an additional tubular element 5. Next, the wire element 1 is wound to form the first turns of said wire element. The wire element 1 passes through a central portion of at least one first tubular element 2 at each turn so that the at least one first tubular element 2 forms at least one first sheath around the first turns of the wire element 1. The first turns of the wire element 1 are installed in the additional tubular element 5. The additional tubular element 5 partially covers the winding to define a first ring for receiving a first carabiner and a second ring for receiving a second carabiner. The second ring is separated from the first ring by the additional tubular element 5.It is particularly advantageous that at least one first sheath surrounds the first turns from the additional tubular element 5 to the additional tubular element 5 along the first ring and the second ring.

[0059] Preferably, the at least first first tubular element 2 comprises a first main tubular element 2' and a first secondary tubular element 2" distinct from the first main tubular element 2'. During winding of the wire element 1 to form the first turns, said wire element 1 passes through the first main tubular element 2' and the first secondary tubular element 2". The first main tubular element 2' covers the first turns along the first ring and the first secondary tubular element 2" covers the first turns along the second ring.

[0060] Advantageously, the at least one first tubular element 2 comprises a first main tubular element 2' and a first secondary tubular element 2" connected to the first main tubular element 2' by a breakable portion. After winding the wire element 1 to form the first turns, the first main tubular element 2' is separated from the first secondary tubular element 2". The first main tubular element 2' covers the first turns along the first ring, and the first secondary tubular element 2" covers the first turns along the second ring.

[0061] Figure IB illustrates an embodiment step where the first tubular element 2 is positioned beyond the additional tubular element 5 to prepare for the formation of the first ring sheath and the second ring sheath. This embodiment is not advantageous because it is preferable to install the ends of the first tubular elements 2 in the additional tubular element 5. It is particularly advantageous to retain the ends of at least one of the first ring and second ring sheaths in the additional sheath and to make the fixing 8 before finalizing the formation of the other of the first ring sheath and the second ring sheath.

[0062] As illustrated in [Fig.6], a quickdraw is formed by installing a carabiner 9 in the first ring 6 and another carabiner 9 in the second ring 7.
