[0002] Mobile strand connector with a pull-up device

[0003] Description

[0004] The invention relates to a mobile strand connector with a tensile receiving device for integration into at least one tensile first strand with a circular cross-section and a minimum bending radius, comprising at least one first pair of drums consisting of two drums around which the first strand is wound at least once completely, and on which a frictional force is exerted.

[0005] Strand connectors are fundamentally used to join two strands. These strands can be either tension-free or tension-loaded. Tension relief devices serve to relieve tension in tension-loaded strands into which they are integrated.

[0006] This protects the strands from tearing, but above all from less visible damage such as crushing or breaking. The strands with a circular cross-section, as described in the invention, can be any type of rope or cable, as well as cables for electrical or data transmission. In the case of pure data transmission, these can also be particularly sensitive fiber optic cables. The invention is also applicable to hoses. For example, on towed underwater exploration vehicles, ropes and cables of various designs are run in parallel. Other applications for mobile strand connectors with tensioning devices can be found, for example, in climbing technology, crane technology, guying technology, or suspension bridge technology. In these applications, the strand connectors are not fixed in place, but can be used mobilized at any location, particularly at height and depth. Prior art

[0007] The prior art closest to the invention is known from US 2,564,036 A. A rope clamp is disclosed in which two drums with an elliptical cross-section are provided, around which the two ends of a rope are wound, forming a hanging loop. The rope is wound clockwise around both drums. Inside the drums are clamping elements that laterally clamp the inserted rope. This can cause damage to the rope. A further disclosure includes a rope clamp with which two ropes can be joined together. In this case, however, each rope is wound only around one drum, with both ropes wound in opposite directions. Again, lateral clamping elements are provided, which can impair the ropes. Impairment can also occur due to the elliptical cross-section of the drums, since their smaller radius is significantly smaller than their larger radius.Both drums are held by two side pieces.

[0008] Furthermore, DE 2 213 695 A discloses a self-locking rope buckle with side plates, in which the rope is wound around two closely adjacent pins in counterclockwise directions. The diameter of the rope is correlated with the diameter of the pins. However, the rope is guided in such a way that it touches itself and clamps itself under tensile stress, thus potentially being damaged.

[0009] From DE 1 756 861 A, a stationary arrangement of two bollards is known, around which a ship's anchor rope is wound several times in the shape of a figure eight. However, this does not provide strain relief because the ship must be moored. From DE 10 2018 125 131 A1, a fastening device with two pulleys for a wire rope is known, wherein the wire rope is clamped between the pulleys, which can lead to damage. From DE 29 06 517 B1, a similar device is known with which a rope is guided and clamped. Problem statement

[0010] Starting from the nearest prior art, the present invention is based on the objective of further developing the generic mobile strand connector with a tensile-receiving device in such a way that the function of at least the first strand is not impaired or even damaged under tensile stress. Furthermore, any strands with and without tensile relief are to be connected to one another. The solution to this objective according to the invention can be found in the main claim and is shown below. Advantageous embodiments can be found in the dependent claims.

[0011] To solve the problem, the invention proposes that the drums have a diameter of at least twice the minimum bending radius of the first strand and that at least the first strand is wound around the two drums of the first drum pair in counterclockwise directions, being wound in a single layer around the drums so that the frictional force is generated exclusively by the drums, and that the side parts are removable and laterally delimit at least the first drum pair.

[0012] The drums in the invention have a round cross-section, the diameter of which is clearly related to the strand to be wound. It is essential to consider the minimum bending radius of the strand. If the strand is bent or kinked with a smaller bending radius, damage will inevitably occur. The more sensitive the first strand is, i.e., the lower its breaking strength, the larger the diameter of the drums must be. This measure alone ensures effective protection of the first strand to be wound, which could be, for example, a fiber optic cable, against damage, including kinking, caused by exceeding the minimum bending radius. Furthermore, the first strand is always wound around both drums in a figure-eight pattern, once clockwise and once counterclockwise.The inevitable twisting of the strand during winding in one direction is reversed when winding in the other direction. This also protects the strand from damage. The first strand is always wound side-by-side in a single layer, ensuring that the tensile force is always applied from below by the drum to the strand under tension. The strand never lies in multiple layers on top of each other (not even at the intersection in the center of the figure-eight), preventing it from interfering with itself under tension. Its breaking strength is not reduced. The first strand can be wound around the drums only once, or multiple times to increase the frictional force. However, each winding always involves one around the drum in one direction followed by one around the other drum in the opposite direction. Lateral rubbing of the strands against each other must be avoided.The restraining and thus strain-relieving frictional force is introduced into the strand exclusively via the drums.

[0013] The mobile strand connector according to the invention, with a strain relief device, is mobile and therefore very flexible. It can be integrated into the tensile, continuous first strand at any point. Integrating strand ends, i.e., using two strands or splitting a strand, is not necessary. Configuring strand ends or assembling auxiliary components, such as eyes, clamps, and crimp connectors, is unnecessary. Within the drums, several strands or strand windings always lie side by side. No significant frictional force is transmitted through any possible lateral contact. The tension on the first strand is absorbed exclusively by friction on the drum. This guarantees gentle loading of the first strand, and its maximum breaking load is not noticeably affected. Existing sensitive elements inside the first strand are not damaged.

[0014] The mobile strand connector according to the invention, with its integrated tension-receiving device, enables the implementation of multiple functions without affecting the first strand. Essentially, the invention relieves the tension on the strand under tension. The use of round drums allows tensile forces to be applied in all directions. This facilitates, for example, the tensioning of the first strand, as is common with overhead power lines and climbing ropes. The integrated tension-receiving device does not reduce the breaking strength of the first strand and does not represent a weak point. It is important to note that tension must always be present in the strand connector and strand system; otherwise, no tensile load will develop. Therefore, at least one incoming and one outgoing strand must always be under tensile load.Furthermore, loads can be attached to the first strand, for example, a base weight in a rope-cable combination for a towed underwater vehicle. Additionally, the first strand does not need to be twisted during attachment, so even large strands, such as anchor ropes of large ships, can be strain-relieved. The mobile strand connector with a strain-receiving device according to the invention is therefore scalable to almost any size.

[0015] Finally, it is also possible to connect two strands of the same or different types with the mobile strand connector under strain relief, without impairing their function or having to utilize their ends. The invention thus allows strand connections to be designed efficiently, saving material and weight. Therefore, according to a first modification of the invention, it is advantageous and preferred if at least the second strand is also subjected to tensile stress and wound around both drums in the first drum pair in counterclockwise directions, with both strands wound side by side and in a single layer around the drums, so that the frictional force is generated exclusively by the drums. This could, for example, involve a rope and an additional or parallel cable that is very sensitive to mechanical stress. Both strands are wound side by side and in only one layer around the drums.This ensures that only frictional force is applied to the strands from the drums. The strands do not overlap, which could cause them to pinch and potentially damage each other. Furthermore, the mobile strand connector according to the invention can also connect multiple strands. For example, ropes can be connected to cables, even if they are coming from different directions. Due to its design, the integrated tensile force-receiving device absorbs tensile forces from almost any direction. It is advantageous if the tensile forces act in opposite directions so that no torque is exerted on the strand connector. The applied strands always tend to align themselves in a straight line, thereby twisting the strand connector accordingly, with the common axis of tension always passing through the center point of the strand connector.The aim is always to achieve a static equilibrium by eliminating tensile forces. However, the occurrence of a torque does not impair the function of the strand connector suspended from the strands, allowing it to assume various positions in space. A horizontally balanced position is also achieved because the distance between the drums is not significantly greater than the strand diameter. This results in a largely torque-free, tangential upward and downward guidance of the strands by the strand connector. With a larger distance between the drums, the strands can also rotate the strand connector along its perpendicular axis to align it with the common tensile axis.

[0016] If only one pair of drums is used for the connection, the drum width limits the number of strands that can be joined, since all strands must be wound side by side in a single layer onto the drums. Therefore, according to a further embodiment of the invention, it is preferred and advantageous to provide additional pairs of drums with further drums for additional strands, which are wound around the further drums in a counterclockwise direction, side by side and in a single layer, so that the frictional force is generated exclusively by the drums. For example, two ropes and two cables can be joined together if two pairs of drums are provided. A strand connection can be designed with or without active strain relief.

[0017] To make the mobile strand connector with a pull-receiving device according to the invention as compact as possible, it is preferred and advantageous in a further embodiment if the drum pairs are arranged around a common center point. The strand connector can be made even more compact if, according to a further modification of the invention, only three drums are provided for each adjacent drum pair, with the other strands being wound side by side and in a single layer onto the central drum, so that the frictional force is generated exclusively by the drums. The central drum is then used jointly for each adjacent strand. This reduces the number of drums required and thus the diameter of the strand connector, thereby increasing its flexibility and mobility.

[0018] In addition to the compactness of the strand connector according to the invention, its ease of handling in use, for example at high altitudes, on steep mountains, or underwater, is also of great importance, especially because the strands are subject to tensile stress. Therefore, according to the invention, the two side parts of the strand connector are designed to be removable, laterally defining the existing drum pairs. To wind the strands, for example, a side part is pulled off the drums. It is then reattached, for example, by simply clicking it onto mechanical catches or by means of simple fastening elements. Furthermore, the side parts can also serve as connections to other elements in conjunction with the tensile support device.It is particularly preferred and advantageous if a weight or suspension is provided, wherein the weight is connected to a lower side and the suspension to an upper side of one or both side parts via further strands, for example ropes, but also rods. For example, preferably and advantageously, both side parts then have corresponding holes into which a weight or a hook can be inserted as a suspension.

[0019] In addition to the compact design of the mobile strand connector according to the invention and its ease of use, it is also advantageous that all essential design elements can be manufactured cost-effectively, particularly using 3D printing. This allows for the simple implementation of different materials and colors, as well as the production of large quantities. Adaptation to the specific application is easily possible.

[0020] A key advantage of the invention, namely that the inserted strands are not pinched or crushed when strain relief is desired, is that all wound strands are arranged side by side and in a single layer on the drums. This ensures that only frictional forces are applied to the strands by the drums, whose diameters are dimensioned according to the sensitivity of the strands being wound. Further protection can be achieved if, according to a further embodiment of the invention, guide discs with azimuthally circumferential concave guide grooves are preferably and advantageously provided between the two side parts, in which the strands are guided. The strands with a round cross-section can be stored particularly gently in the concave guide grooves. This is of particular importance when winding especially sensitive cables, such as fiber optic cables.Since the strands cannot slide through the guide grooves on their own, no retaining elements are required in this embodiment when the inserted strands are not under tensile load. Furthermore, it is preferred and advantageous to provide spacer discs without circumferential guide grooves, arranged between the guide discs, with the thickness of the spacer discs corresponding to the thickness of the guide discs. This effectively prevents adjacent strands from rubbing against each other, which can potentially lead to problems with particularly sensitive strands. Additionally, by staggering the arrangement of the guide and spacer discs, the crossing points of the strands can be distributed across two planes.

[0021] Since, in the integrated tension-receiving device of the invention, the force is absorbed exclusively by friction between the drums and the wound strands (any type of clamping or crushing element is omitted), the wound strands could unwind to some extent when not under tensile stress. To optionally prevent this potential unwinding, a further modification of the invention recommends and considers it advantageous to provide retaining elements outside the drums that hold the first strand down on the drums when it is not under tensile stress. According to a further embodiment of the invention, these retaining elements can preferably and advantageously be designed as eccentric rollers. When the strands are inserted into the tension-receiving device, the eccentric rollers can simply be rotated, thus securing the strands, when not under tensile stress, on the drums.However, like the guide grooves, which also prevent the unloaded strands from lifting off, they do not exert any damaging influence on the strands. Further explanations of the present invention and its respective modifications can be found in the exemplary embodiments shown below.

[0022] Examples of implementation

[0023] The strand connector with integrated tensile-receiving device claimed in the present invention and its preferred modifications are explained in more detail below using exemplary embodiments to better understand the invention. The following section shows the

[0030] Fig. 8 is a schematic perspective view with two drums and discs.

[0031] Figure 1 schematically depicts, in exploded view, a mobile strand connector with a pull-holding device 01 and a first drum pair 02 consisting of two drums 03, 04. The drums 03, 04 have a diameter D of at least twice the minimum bending radius of the strands (ropes, cables, or hoses) to be inserted. A rear side panel 05 and a front side panel 06 are also visible. Each side panel 05, 06 is spectacle-shaped and has openings 07 with diameter D in the area of ​​the drums 03, 04. A version of the side panels 05, 06 without openings 07 is also possible; however, the openings 07 save material and make handling the mobile strand connector with pull-holding device 01 more convenient. Closed rings 08, which form the drums 03, 04, are arranged on the rear side panel 05. The front side panel 06 is shown in the disassembled position.Several anti-return devices 09 are arranged on the rear side panel 05. In the illustrated embodiment, these are rotatable eccentric rollers 10. These serve to hold down inserted strands when they are not under tensile stress. Bolts 11 are also arranged on the eccentric rollers 10, which extend through bores 12 in the front side panel 06 during assembly. By means of fixing elements 13, which are connected to the bolts 09 (in the embodiment, these are simple screws), the front side panel 06 is fixed after the strands have been wrapped around the drums 03, 04. Figure 2 schematically shows a first strand arrangement ("loading") of the mobile strand connector with tension receiving device 01 according to Figure 1.A tensile first strand 14 with a round cross-section, which in this embodiment is a rope, comes from above and is wound clockwise around the left drum 03 and then counterclockwise around the right drum 04. The first strand 14 then exits the mobile strand connector with tension receiving device 01 at an angle downwards. The first strand 14 can also be wound alternately around the drums 03 and 04 multiple times, but it is always wound in only one layer. In principle, there is always only one layer of at least the first strand 14 on each drum 03 and 04. The required frictional force is generated exclusively via the drums 03 and 04. Clamping and crushing elements are completely omitted in the mobile strand connector with tension receiving device 01. The strand 14 is shown interrupted at the crossing point in the middle of the figure eight, which serves to better illustrate the directions of rotation.Of course, strand 14 is wound continuously.

[0032] The application shown serves to attach a weight 15 to a lower side 16 of the side parts 05, 06. The weight 15 can also be attached to only one side part 05, 06, but this results in a corresponding tilt. Attaching it to both side parts 05, 06 is more advantageous. By attaching the weight 15, an upper section 17 of the first strand 14 above the mobile strand connector with tensioning device 01 is stabilized vertically, whereas a lower section 18 of the first strand 14 below the mobile strand connector with tensioning device 01 is relieved of tension. For example, this could be an application involving a towed underwater robot. The robot is lowered to the desired depth, and then the mobile strand connector with tensioning device 01 is attached to the first strand 14 underwater.The upper section 17 of the first strand 14 originates from the ship, while the lower section 18 of the first strand 14 leads to the underwater robot. The side sections 05, 06 are mirror-symmetrical and have two bores 19. The weight 15 can be suspended in the lower bore. A suspension can be attached to the upper bore 19 on an upper side 20 of the side sections 05, 06. This suspension is particularly useful in applications of the mobile strand connector with a pull-up device 01 and a fixed base, for example, in crane technology.

[0033] Figure 3 schematically illustrates a second strand configuration ("spreading") of the mobile strand connector with tension receiving device 01 according to Figure 1. In this case, the tensile first strand 14, again a rope, and a tensile second strand 21, in this case a cable, are guided parallel to each other up to a predetermined spreading point and then split in different directions. For this purpose, the mobile strand connector with tensioning device 01 is connected at the spreading point to the continuous first strand 14 and the continuous second strand 21. Both strands 14 and 21 run side by side in the left drum 03 in a clockwise direction and in the right drum 04 in a counterclockwise direction. Below the mobile strand connector with tension receiving device 01, the first strand 14 is then directed in a different direction than the second strand 21.The mobile strand connector with tension-receiving device 01 serves not only as a tension relief device but also as a spreading device between the first strand 14 and the second strand 21. For better differentiation from the first strand 14, the second strand 21 is shown with dashed lines. Furthermore, strands 14 and 21 are shown with a break at the intersection point in the middle of the figure eight, if necessary. This also serves to improve clarity. However, strands 14 and 21 are, of course, wound continuously.

[0034] Figure 4 schematically shows a third strand configuration (“crossing”) of the mobile strand connector with pull-in device 01 according to Figure 1. It differs from the strand configuration according to Figure 3 in that the first strand 14 (rope) and the second strand 21 (cable) are not guided parallel above the mobile strand connector with pull-in device 01, but rather come from different directions. Thus, a crossing between a rope and a cable is formed.

[0035] Figure 5 schematically illustrates a fourth strand configuration (“connection”) of the mobile strand connector with tension-receiving device 01 according to Figure 1. This differs from the previously shown strand configurations in that the mobile strand connector with tension-receiving device 01 is not integrated into continuous strands 14, 21, but rather connects the first strand 14 to the second strand 21 with its aid. Each of the two strands 14, 21 thus terminates at the mobile strand connector with tension-receiving device 01. However, this does not change the basic principle of winding and tension relief. The free ends 22 of the two strands 14, 21 can be used during winding, but this is not mandatory.

[0036] Figure 6 shows an embodiment of the mobile strand connector with pull-in device 01 in a perspective exploded view, showing the first drum pair 02 with drums 03, 04 for the first strand 14 and a further drum pair 23 with additional drums 24, 25 for further strands, for example, the second strand 21. The strand assignments described above can now be implemented in double configuration. However, several additional strands can also be wound. For this purpose, the drum pairs 02, 23 can be used, or adjacent drums 03, 04, 24, 25 can be wound from the two drum pairs 02, 23. This creates two additional drum pairs 26, 27, which can be wound in a single layer clockwise and counterclockwise. Thus, for example, four ropes or cables can be joined together.Two backstops 09 (again eccentric rollers 10) can also be seen on each drum 03, 04, 24, 25 to secure all strands 14, 21 when they are not under tensile stress.

[0037] If several strands 14, 21 are to be wound side by side in a single layer onto a drum 03, 04, 24, 25, the drum must have a corresponding width. With a very large number or thickness of strands 14, 21, the mobile strand connector with tension-receiving devices 01 can become unwieldy. It is therefore preferable to wind only the first strand 14 or, at most, the second strand 21 onto a drum 03, 04, 24, 25. The mobile strand connector with tension-receiving device 01 according to Fig. 6 shows two pairs of drums 02, 23, each of which can only be wound by one strand 14, 21. Connecting one rope or cable to a second rope or cable is the most common embodiment of the mobile strand connector with tension-receiving device 01. To achieve a more compact embodiment, adjacent drums can again be used together, as shown in Fig. 7.The drum pairs 02 and 23 thus share drum 04 and 25 respectively, so that only these are wrapped by both strands 14 and 21. A more compact design of the mobile strand connector with pull-up device 01 can be achieved. Alternatively, all three formed drum pairs 02, 23, and 26 can again be used, for example, to connect three ropes or cables together.

[0038] The mobile strand connector with tensile strength device 01 is designed to prevent damage to strands in the form of ropes and cables that are being redirected, tensioned, or joined, thus avoiding a reduction in their breaking load. Some cables, such as multi-core data cables or fiber optic cables, are particularly sensitive. Generally, the frictional force between the individual turns of a strand in a single layer on a drum is so low that no damage occurs that would reduce the breaking load. However, to further reduce this risk for particularly sensitive strands, guide discs 28 with azimuthally circumferential, concave guide grooves 29 and spacer discs 30 can be provided on the drums, as shown in the perspective exploded view in Fig. 8. The guide grooves 29 prevent the strands 14, 21 from lifting off when they are not under tensile stress.The rear side panel 05 with the closed rings 08, which form the drums 03 and 04, is visible. During assembly, a guide disc 28 is slid onto the left drum 03 and a spacer disc 30 onto the right drum 04. Then, a spacer disc 30 is placed on the left drum 03 and a guide disc 28 on the right drum 04. Finally, spacer discs 30 can be placed on both drums 03 and 04, for example, to compensate for the width of the drums 03 and 04 and to prevent the first strand 14 from slipping. The first strand 14, for example, a fiber optic cable, is inserted into the azimuthal (i.e., circumferential) guide grooves 29 of the two guide discs 28 in a figure-eight pattern around the two drums 03 and 04. The assembly is then completed by mounting the front side panel 06.The concave guide grooves 29 are rounded inwards and can support the first strand 14 particularly gently. The guide grooves 29 provide axial guidance for the first strand 14. By offsetting the guide discs 28 between the two drums 03, 04, the intersection point of the first strand 14 is formed across two planes. The spacer discs 30 reliably prevent crushing when the mobile strand connector with tension-receiving device 01 is assembled. Within an acceptable width for the drums 03, 04, several guide discs 28 and spacer discs 30 can be applied. These can also be manufactured by 3D printing and dimensioned accordingly in thickness; for example, the guide discs 28 and spacer discs 30 can be of the same thickness, with the thickness of the guide discs 28 depending on the width of the guide grooves 29, which in turn depends on the width of the strands 14, 21 to be inserted.
