Description

Technical Field

[0001] This utility model relates to an adjustment device for a line element and a rope fitting having such an adjustment device. Background Technology

[0002] Adjusting buckles are typically used to adjust the length of webbing, and more generally, the length of the thread elements. Over the years, a large number of adjusting buckles with different configurations have been developed.

[0003] In the traditional method, the adjusting buckle has two roughly rectangular rings that are mounted on top of each other and have different sizes. The smaller ring moves relative to the larger ring to wedge into the thickness of the strip, thereby achieving a clamping length of a selected length.

[0004] This solution yields good results in maintaining the selected length, including when the tensile stress applied to the strip increases. The buckle can be easily loosened and the adjustment modified by moving the two loops relative to each other. However, this construction has also been observed to lead to a significant decrease in the mechanical properties of the belt.

[0005] However, when the strip is used alone and stretched longitudinally, it is measured to provide the initial breaking strength value. It was observed that when the assembly is subjected to the same longitudinal force, adding an adjusting buckle results in a halving or reduction to one-third of the breaking strength. The breakage occurs at a much lower value and is not caused by the breakage of the adjusting ring. To withstand the expected stress, the solution lies in replacing the original strip with a thicker and / or wider strip.

[0006] This technical choice is not satisfactory because increasing the cross-section of the strip compromises general ergonomics.

[0007] Document US2023 / 0065262 discloses a rope fitting equipped with a connector designed to attach to a belt on one side and to a leg loop on the other side via two length-adjustable straps. In addition to two slots for the adjustable straps, the connector also defines two loops. The connector allows attachment of a cam locking device, enabling adjustment of the rope length connecting the right and left connectors. The cam locking device defines a hole for a single rope to pass through. The hole is defined by a pivoting, spring-loaded cam to clamp the rope. Utility Model Content

[0008] One object of this invention is to provide an adjustment device that ensures good maintenance of the selected length and achieves improved breaking strength compared to prior art constructions using equivalent wire elements, while being easy to use and particularly easy to adjust.

[0009] This result tends to be achieved through an adjustment device configured to adjust the length of the line element, the adjustment device comprising:

[0018] According to one feature of this utility model, the second surface of the support wall is provided with a barb, which is designed to be inserted into a wire element.

[0019] In an advantageous manner, the clamping element defines a through-hole through which the bearing wall passes, the height of the bearing wall being less than the height of the through-hole in the pivoting direction of the clamping element, thereby applying pivoting of the clamping element within a predetermined angular range.

[0020] In a particular configuration, the primary direction of the body is curved.

[0025] Preferably, the bearing wall has a circular cross-section and / or the clamping element defines a bypass area by means of a line element, the outer surface of which is part of an arc.

[0026] In another advantageous improvement, the main body is pivotally mounted relative to the support about an additional pivot axis.

[0027] In a preferred embodiment, the second wall forms an additional pivot axis.

[0028] Advantageously, the main body is defined by a fastening ring that is different from the first and second holes.

[0029] Preferably, the clamping element is formed of an inner portion and an outer portion, both pivotally mounted around a first wall, the outer portion being mounted to be movable relative to the inner portion with a limited functional clearance, the inner and outer portions being separated by a support wall.

[0056] Figures 1 to 11 Different embodiments of a tether with an adjustment device 1 configured to adjust the length of a line element 2 are shown, and a rope fitting 3 with such a tether having the adjustment device 1 is shown.

[0057] The adjustment device 1 includes a main body 4 and a clamping element 5. The clamping element 5 is fixed to the main body 4 and is movably mounted relative to the main body 4.

[0058] The body 4 is a perforated element designed for the wire element 2 to pass through. The body 4 has at least a first wall 6, a supporting wall 7, and a second wall 8 to define at least a first hole 9 and a second hole 10 designed for the wire element 2 to pass through. The first hole 9 is partially defined by the first wall 6. The second hole 10 is partially defined by the second wall 8. The second hole 10 is different from the first hole 9 and is separated from the first hole 9 by the supporting wall 7.

[0059] Figure 12 and Figure 13 Two embodiments of the main body 4 are shown. Figure 12In the illustrated embodiment, the body 4 defines only the first hole 9 and the second hole 10. The body 4 is in the form of a ring, and its supporting wall divides the central hole into the first hole 9 and the second hole 10. Figure 13 In the illustrated embodiment, the body 4 defines additional through holes in addition to the first hole 9 and the second hole 10. The body 4 may have more holes or through holes. The body 4 is preferably a non-deformable element, such as aluminum or steel. In other words, the supporting wall 7 is fixedly arranged relative to the first wall 6 and relative to the second wall 8.

[0060] In a preferred embodiment, the first hole 9 is defined by the first wall 6 and the supporting wall 7, and the second hole 10 is defined by the second wall 8 and the supporting wall 7, as shown below. Figures 1 to 13 As shown. To facilitate easy adjustment of the length of the wire element 2, it is advantageous that the width and height of the first hole 9 and the second hole 10 are both greater than the width and thickness of the wire element 2. When the wire element 2 is a strip or any other element whose width is significantly greater than its thickness, the first hole 9 and / or the second hole 10 may have a rectangular cross-section.

[0061] The adjusting device has a clamping element 5 arranged to move between a clamping position and a release position. In the clamping position, the clamping element 5 clamps the wire element 2. In the release position, the clamping element 5 allows the wire element 2 to slide relative to the body 4. The clamping element 5 is mounted to be pivotable relative to the body 4 about a pivot axis 11 to move toward or away from the support wall 7. The pivot axis 11 is positioned in a first direction passing successively through the first wall 6, the support wall 7, and the second wall 8, closer to the first wall 6 than the second wall 8, and closer to the first wall 6 than the support wall 7. Figure 13 A specific embodiment of the clamping element 5 is shown in the figure.

[0062] The clamping element 5 has a support wall 12 and preferably a gripping portion 13. The gripping portion 13 and the support wall 12 define a channel hole 14 for the wire element 2 to pass through.

[0063] The wire element 2 is divided into a first strand 2a and a second strand 2b. The first strand 2a of the wire element 2 passes through the second hole 10 and the channel hole 14. The first strand 2a extends along the first surface of the support wall 12 and around the first wall 6. The second strand 2b of the wire element 2 passes through the second hole 10 and extends along the second surface of the support wall 12, around the bearing wall 7, and passes through the body 4 via the first hole 9. As it continues to extend, the second strand 2b wraps around the first wall 6 to form the first strand 2a. As shown, the wire element 2 forms a loop around the first wall 6.

[0064] In other words, the first strand 2a and the second strand 2b pass through the body 4 via the second hole 10. The two strands extend in the direction of the first wall 6, then pass around the first wall 6 and join together. The two strands are separated by the support wall 12. The second strand 2b passes through the body 4 again via the first hole 9 and passes around the first wall 6 to join the first strand 2a. The second strand 2b is located between the bearing wall 7 and the support wall 12. The support wall 12 is located between the first strand 2a and the second strand 2b. When the second strand 2b is tensioned, it causes the support wall 12 to pivot toward the bearing wall 7. When the second strand 2b is located between the support wall 12 and the bearing wall 7, the first strand 2a exerts a force on the support wall 12 in the direction of the bearing wall 7, thereby pressing the first strand 2a against the bearing wall 7 and clamping the wire element 2 at a selected position against the bearing wall 7. The clamping element 5 is in the clamping position. The wire element 2 passes through the body 4 via the second hole 10 and passes around the bearing wall 7. The two wires follow different paths, so that they loop around the first wall 6 and the supporting wall 12, and when the first wire 2a is pulled, the second wire 2b can be sandwiched between the bearing wall 7 and the supporting wall 12.

[0065] The greater the tension applied to the first strand 2a, the greater the force applied by the support wall 12 to the second strand 2b to hold it in place. The first strand 2a is a tensioned strand, while the second strand 2b is a free strand.

[0066] In the clamping position, the clamping element 5 presses the second strand 2b against the support wall 7, thereby clamping the second strand 2b. In the released position, the clamping element 5 and the support wall 7 define a functional gap to allow the second strand 2b to slide. In the clamping position, the force applied by the first strand 2a presses the first strand 2a against the support wall 12, and presses the support wall 12 against the second strand 2b. The strand element 2 is locked by friction, rather than by compression as in prior art constructions. The support wall 12 prevents direct friction between the first strand 2a and the second strand 2b.

[0067] In a preferred embodiment, to keep the second strand 2b clamped, the support wall 12 may be provided with barbs 15, teeth, or any other means capable of being inserted into the second strand 2b. The barbs 15 allow the second strand 2b to remain in place even when the tension in the first strand 2a decreases. Particularly advantageously, the barbs 15 are arranged facing the area of ​​the support wall 7 around which the second strand 2b is wound, as this facilitates contact between the barbs 15 and the second strand 2b, which will tend to conform to the shape of the support wall 7. Wandering can be at least 180°, preferably at least 270°.

[0068] exist Figures 1 to 11In the illustrated embodiment, the pivot axis 11 that enables the clamping element 5 to pivot relative to the body 4 also forms the first wall 6. In other words, the clamping element 5 is arranged to pivot relative to the body 4 about the first wall 6. In this particular case, the first wire 2a and the second wire 2b pass around the first wall 6, which also forms the pivot axis 11, to connect with each other.

[0069] exist Figure 15 In the alternative embodiment shown, the body 4 defines more holes than the first hole 9 and the second hole 10. The pivot 11 is not formed by the first wall 6. The clamping element 5 defines additional holes, allowing the wire element 2 to pass through the support wall 12 and allowing the first strand 2a to be continued by the second strand 2b. The operation of the clamping element 5 is the same as described above with respect to the first strand 2a, which is designed to press the support wall 12 against the second strand 2b and against the bearing wall 7 to fix the position of the second strand 2b.

[0070] To facilitate actuation of the clamping element 5 to the release position, it is advantageous that the clamping element 5 is provided with a gripping portion 13. In the illustrated embodiment, the gripping portion 13 is mounted facing the support wall 12 and the bearing wall 7 when the clamping device 5 is in the clamping position. This face-to-face mounting defines the channel hole 14.

[0071] Another configuration of the gripper 13 is possible, for example by positioning the gripper 13 in an offset manner relative to the support wall 12 in a direction parallel to the pivot axis of the clamping element 5.

[0072] It is particularly advantageous to secure the clamping element 5 to the body 4 and to movably assemble the latter relative to the body 4, as they ensure that the position of the second strand 2b is maintained, including when the body 4 moves.

[0073] exist Figures 3 to 11 In the illustrated embodiment, the body 4 is movably mounted relative to the support 16. In a preferred embodiment, the body 4 is pivotally mounted relative to the support 16. In an even more preferred embodiment, the body 4 is mounted to pivot about an additional pivot axis formed by the second wall 8 or another wall.

[0074] The support member 16 defines a through cavity 17, and the second wall 8 passes through the through cavity 17. Preferably, the additional pivot axis of the body 4 relative to the support member 16 mainly includes a component parallel to the pivot axis of the clamping element 5 relative to the body 4.

[0075] The tensioning of the first strand 2a causes the body 4 to move to the side with the clamping element 5. As the body 4 is guided to move in the opposite direction relative to the support 16, the body 4 and the clamping element 5 move in a direction that tends to increase the tensile stress in the first strand 2a, keeping the second strand 2b clamped against the bearing wall 7. The same occurs when the body 4 moves in the direction of the end of the first strand 2a not fixed to the body 4. This movement can result in a reduction of the stress in the first strand 2a. Using barbs 15 to ensure good attachment may be advantageous.

[0076] Because of its construction with two holes separated by the supporting wall 7, the body 4 is able to clamp the wire element 2 wound around the supporting wall 7, with the two strands of the wire element 2 joined together around the first wall 6. However, once the wire element 2 has been clamped and tensioned, it is very difficult or even impossible to move the wire element 2 within the body 4. Therefore, it is particularly advantageous to use a clamping element 5 that is movably mounted relative to the body 4. By moving the clamping element 5 away from the supporting wall 7 relative to the body 4, the value of the force exerted on the second strand 2b by the supporting wall 12 can be reduced. The reduced force value allows the first strand 2a and the second strand 2b to slide.

[0077] Slackline users are familiar with a device marketed as "Banana," which has a body defining two holes for the strip to pass through and performs the function of clamping the strip. The "Banana" device is used to clamp the strip to the desired length. It is used in conjunction with an adjustment mechanism (such as a ratchet tensioner) that stretches the strip and then loosens it at the end of use. However, in practice, easy adjustment of the tensioned strip length is not required. The "Banana" device does not allow for adjustment of the tensioned strip length.

[0078] When the support wall 12 is provided with a barb, the sliding of the second strand 2b is possible when the support wall 12 reaches a threshold position that substantially corresponds to the position where the barb 15 is no longer inserted into the wire element 2.

[0079] To facilitate the movement of the clamping element 5 from the clamping position to the release position, it is advantageous that the adjusting device is provided with a gripping part 13, and more particularly, the gripping part 13 is fixed to the clamping element 5 and pivotally mounted relative to the clamping element 5, so that the position of the gripping part 13 is better matched with the direction of the force applied to move the support wall 12 away from the bearing wall 7.

[0080] Particularly advantageous is that the supporting wall 7 has no sharp edges to prevent shearing of the wire element 2 when it is subjected to high stress. More preferably, the contact surface with the wire element 2 is curved, and the supporting wall 7 advantageously has a circular cross-section.

[0081] It is also advantageous that the contact area between the wire element 2 and the first wall 6 does not have any sharp edges. Advantageously, the first wall 6 has a curved surface and preferably a circular cross-section. However, if the wire element 2 only contacts the clamping element 5, rather than as... Figures 2 to 11 Since the first wall 6 is in contact with the clamping element 5, the cross-section of the first wall 6 is not very important. It is then advantageous that the portion of the clamping element 5 designed to be covered by the wire element 2 is a curved surface, and more preferably an arc.

[0082] Figure 1 and Figure 2 An embodiment of an adjustable-length tether is shown. The tether has a wire element 2 and a body 4, the body 4 defining a fastening ring designed for attaching a connector. As described above, as long as the clamping element 5 is in the clamping position, the orientation of the body 4 relative to the longitudinal axis of the first wire 2a will not affect the clamping of the second wire 2b. The gripping part 13 can be pivotally mounted about a gripping shaft 18, which is fixed to the clamping element 5. The gripping shaft 18 is mounted statically relative to the clamping element 5.

[0083] The movement of the clamping element 5 relative to the body 4 becomes easier, thereby making it easier to extend the effective length of the wire element 2 when the first strand 2a is tensioned.

[0084] Figures 3 to 11 An embodiment is shown in which the main body 4 is pivotally mounted relative to the support member 16. Figure 3 , Figure 4 , Figure 7 and Figure 8 Two different embodiments of the main body 4 are shown, in which the clamping element 5 is in the released position. Figure 5 , Figure 6 , Figure 9 and Figure 10 Two different embodiments of the main body 4 are shown, wherein the clamping element 5 is in the clamping position.

[0085] Figures 3 to 6 An embodiment is shown in which the main body 4 is curved, i.e., the direction in which the first wall 6, the supporting wall 7 and the second wall 8 are connected in sequence is curved.

[0086] Figures 7 to 10 An embodiment is shown in which the main body 4 is flat, i.e., the direction in which the first wall 6, the supporting wall 7 and the second wall 8 are connected in sequence is a straight line.

[0087] In a particular embodiment, the clamping element 5 is mounted to be movable relative to the body 4 within a limited angular range, for example, less than 20°. The clamping element 5 defines a through-hole, and a support wall 7 passes through the through-hole. The size of the through-hole is larger than the size of the support wall 7 to allow relative movement between the clamping element 5 and the support wall 7. The difference in size between the support wall 7 and the wall defining the through-hole limits the movement of the clamping element 5 relative to the support wall 7. Limiting the angular range of the clamping element 5 ensures that the clamping element 5 will clamp the second strand 2b after tension is applied to the first strand 2a.

[0088] Figure 11 The rope device 3 is shown, which is provided with a belt forming a support 16 and a pair of leg loops 29. The tether is secured to the belt by means of a body 4 fixed to a through cavity 17.

[0089] exist Figure 11 In the specific embodiment shown, the tether has a connector 19 at one end of the first strand 2a. The tether with the connector 19 is secured to the belt, and the connector 19, attached to the anchor point, can support the user suspended in the rope device 3.

[0090] In a preferred embodiment, connector 19 is non-removably secured to the first strand 2a. Adjustment device 1 is configured to move connector 19 toward or away from the belt.

[0091] In an advantageous embodiment, connector 19 is also secured to leg loop 29 such that the force associated with the weight of the user suspended in the seatbelt is shared between the belt and leg loop 29.

[0092] Preferably, the rope harness 3 has two tethers, one attached to the right side of the belt and the other attached to the left side of the belt. The left and right sides are separated by the midsagittal plane of the user wearing the rope harness 3.

[0093] More advantageously, the two connectors 19 form a right connector and a left connector, which are attached to the right portion of the right leg loop and the right portion of the waist belt, or to the left portion of the left leg loop and the left portion of the waist belt, respectively. It is then advantageous to attach a movable anchor point 20 to both connectors 19, and more preferably to the two connectors, and to allow the movable anchor point 20 to move along the flexible connector 21, for example, by sliding along the flexible connector 21. The flexible connector 21 can be a rope or a strip. The movable anchor point 20 can be a loop.

[0094] The belt may also be equipped with geared slings 22 and any other equipment required for user practice. The line element 2 is preferably a strip or any other element whose length is greater than its width and whose width is greater than its thickness.

[0095] Figure 14An embodiment of the clamping element 5 is shown. The clamping element 5 defines a first through-hole 5a through which the first wall 6 passes to form a pivot shaft 11. The clamping element 5 defines a second through-hole 5b through which a bearing wall 7 passes, in order to limit the angular movement that allows the clamping element 5 to pivot relative to the body 4. The first through-hole 5a and the second through-hole 5b are preferentially disengaged from each other.

[0096] Advantageously, the clamping element 5 defines a portion having a shape complementary to that of the bearing wall 7, so as to have strong contact between the second strand 2b and the clamping element 5, thereby making it easier to maintain clamping integrity when the tensile stress in the first strand 2a decreases. In the illustrated embodiment, the clamping element 5 does not have a gripping portion 13.

[0097] Figure 15 An alternative embodiment is shown in which the wire element 2 does not bypass the pivot shaft 11. In addition to the first hole 9 and the second hole 10, the body 4 also defines one or more additional holes. The clamping element 5 defines a through opening at the end of the support wall 12 to allow the first strand 2a to pass through from the first face of the support wall 12 along the other face of the body 4, bypassing the first wall 6 and forming the second strand 2b. As in the previous embodiment, the tension applied to the first strand 2a presses the support wall 12 against the bearing wall 7, thereby wedging the second strand 2b.

[0098] exist Figures 1 to 15 In this configuration, the clamping element 5 exists as a single piece. However, the clamping element 5 can also be formed as multiple parts, for example, having an inner part 5' and an outer part 5'. The inner part 5' is... Figure 16 As shown in the diagram, the outer part 5” is in Figure 17 and 18 The figures are shown in top and bottom views respectively.

[0099] The internal portion 5' may define one or more first hooks 23, which are designed to latch onto and pivot relative to the first wall 6. The first hooks 23 operate in the same manner as the wall defining the first through-hole 5a. The internal portion 5' also defines one or more second hooks 24, which are designed to receive the supporting wall 7. The internal portion 5' has openings to allow the wire element 2 to pass through. The internal portion 5' may be provided with arms 25 connecting the first hooks 23 and the second hooks 24.

[0100] The outer portion 5” defines one or more hooks 26, which are designed to receive the bearing wall 7. The outer portion 5” defines barbs 15.

[0101] The inner portion 5' is arranged to be movable relative to the outer portion 5" and the inner portion 5' and the outer portion 5" are arranged to pivot independently about the first wall 6 in a movable manner.

[0102] The space between the inner portion 5' and the outer portion 5" defines a channel hole 14. Preferably, the channel hole extends through at least one through-hole in the top portion 5" as shown below. Figure 17 and Figure 18 As shown.

[0103] Particularly advantageous is that the inner portion 5' is movable relative to the outer portion 5" with a limited functional clearance. In the illustrated embodiment, both the inner portion 5' and the outer portion 5" define holes 27 facing each other. A rod 28 passes through both holes 27 to restrict the movement of the outer portion 5" relative to the inner portion 5'. Figure 20 and Figure 21 As shown, the inner portion 5' and the outer portion 5" are separated by the bearing wall 7. The outer portion 5" forms the supporting wall 12.

[0104] exist Figure 21 In the embodiment shown, the inner portion 5' and the outer portion 5" are attached to the body 4. The body 4 is designed to be fixed to the support member 16.

[0105] The first wire 2a passes beneath the first wall 6 and the supporting wall 7, which pass through the second hole 10. The second wire 2b passes through the channel hole 14 and over the outer portion 5”. The first wire 2a extends from the second wire 2b, which wraps around the first wall 6 and passes between the first wall 6 and the first wire 2a. The second wire 2b wraps around the supporting wall 7. The second wire 2b is located between the supporting wall 7 and the outer portion 5”. The second wire 2b disengages from the clamping element 5 by passing between another portion of the first and second wires.

[0106] The tensioning of the first strand 2a and the second strand 2b has the effect of moving the outer portion 5” in the direction of the supporting wall 7 and pressing the outer portion 5” against the second strand 2b. The second strand 2b is wedged against the supporting wall 7 and the outer portion 5”. The first strand 2a presses both portions of the second strand 2b against the inner portion 5’ and / or against the first wall 6. When the strand is tensioned, the force applied to the outer portion 5″ to move it away from the inner portion 5′ and away from the supporting wall 7 reduces the clamping force on the second strand 2b, making the strand easier to move and thus making the wire element easier to relax.
