Description
Title of the invention: Universal continuous belay system
[0001] The present invention relates to the technical field of personal fall protection systems. More particularly, the invention relates to a universal continuous belay system for a lifeline to ensure maximum user safety.
[0002] Belaying is a technique used in the field of working at height to maintain tension on a cable system in order to prevent falls and injuries to users. Belaying systems may consist of cables kept under tension at great heights to ensure the safety of people who might fall. Continuous belaying systems eliminate the need for rope transfers and are used to ensure the safety of participants throughout their route.
[0003] However, continuous belaying systems are complex and include many moving parts that require frequent inspections to prevent failures.
[0004] Furthermore, the belaying of these systems encounters safety problems during cable changes. Indeed, at these precise moments, the user may no longer be secured to the belaying systems by detaching themselves from one cable without securing themselves to another cable of the system. It is at these moments that most accidents occur.
[0005] There is therefore a need for a belaying system that is easy to assemble, customizable and includes many safety features, while allowing a maximum level of safety to be provided to the users of such a system.
[0006] The invention relates to a universal continuous belaying system, making it possible to guarantee maximum safety for users by maintaining a belay in a continuous manner, easy to use, set up and maintain.
[0007] The present invention also relates to personal fall protection systems. More particularly, a continuous belay system that protects a user against falls in an environment with elevated positions, while offering the possibility of moving along the belay system and making transitions within it, with increased mobility and convenience.
[0008] One of the objectives of the present invention is the securing of aerial adventure parks which may include zip lines, elevated obstacle courses or other extreme adventure structures.
[0009] Furthermore, many existing systems do not allow a smooth transition from one point to another, but the present invention solves this problem by arranging all the components in such a way as to eliminate sharp edges in which a participant could get stuck.
[0010] Thus, the invention proposes a simplified system with few moving parts to eliminate weak points and accidental unlocking. This system is easy to use, adaptable to various applications, and requires fewer personnel for operation. It uses a single continuous cable or several crimped cables to provide a single, unbroken cable strip.
[0011] The passage of the engagement hook through the various components is smooth and easy. This invention also introduces safety features that allow for rapid inspection of wear on components most important for participant safety, such as the engagement hook. This rapid inspection allows for the immediate replacement of worn components, without the need for costly and time-consuming in-depth inspections.
[0012] Moreover, the present invention can be adapted and configured for other purposes, including, but not limited to, a safety system for construction sites, climbing expeditions, air shows, fall protection in industry and construction, or other similar applications.
[0013] To this end, a universal continuous belaying system has been developed according to the invention, comprising at least one cable system, at least one engagement hook with said cable system, at least one bifurcation device, at least one tension anchor device for a cable of the cable system intended to be fixed and / or temporarily attached to a support surface, at least one junction device arranged at the free ends of the cable system, said bifurcation, anchoring and junction devices being fixedly mounted on the cable system, the engagement hook being slidably mounted on the cable system and is capable of sliding along the whole of the cable system, bifurcation, anchoring and junction devices continuously.
[0014] The term "joining device" refers to the fact that this device allows the joining of two cable systems of the universal continuous belay system, so as to continuously belay a user. In other words, the joining device allows the transition from one cable system to another without requiring the disengagement of the engagement hook from the belay system.
[0015] It is then understood that the user never finds himself disengaged from the belaying system, consequently limiting the risks of accidents, in particular due to a change of belaying or the user may no longer find himself insured by the system.
[0016] Advantageously, a user is intended to be continuously insured with said cable system.
[0017] Preferably, several anchoring devices are arranged along a cable of the cable system in order to attach and hold said cable in position to a structure and / or surface intended to be traversed safely by a user.
[0018] Similarly, the belaying system includes several bifurcation devices along the same cable to allow for changes of direction, but also for overtaking between users secured on the same cable system.
[0019] The bifurcation device allows the user to move in all directions without needing to disengage from the cable system.
[0020] Thus, the user of such a belaying system is perpetually belayed to the cable system in order to eliminate moments of absence of belaying of the user to the belaying system such as during a change of direction and / or a change of cables of the cable system.
[0021] Therefore, the present invention can be used in different configurations for various applications, including, but not limited to, climbing, descending, branching off paths, evacuation points, swings or overtaking on professional or tourist lifelines.
[0022] In a particular embodiment, the at least one engagement hook comprises a C-shaped body forming a first cavity, a second cavity formed in the C-shaped body, a first and a second retaining element, a space for the C-shaped body to be inserted, said second cavity passes through the body in a manner substantially parallel to the first cavity, the first and second retaining elements are mounted through the C-shaped body in a manner substantially parallel to the first cavity, said first and second retaining elements are arranged at the level of the space for the insertion, in a manner opposite to each other.
[0023] In a particular embodiment, the engagement hook is intended to be attached, at the level of the second cavity, to the user via a connection system, such as a lanyard.
[0024] In a particular embodiment, the first and second retaining elements are similar or different.
[0025] Preferably, the first and second retaining elements are a first and a second stud.
[0026] In a particular embodiment, the first cavity has a substantially hexagonal shape with rounded edges, said rounded edges serve as a guide for the engagement hook and allow the engagement hook to adapt to the bifurcation, tension anchoring and joining devices securely and without risk of slippage.
[0027] In a preferred embodiment, the second cavity is circular in shape to ensure uniform pressure distribution, which prolongs the life of the engagement hook.
[0028] Preferably, the interlocking space of the engagement hook forms a first dimension and the first cavity forms a second dimension, said second dimension being larger than the first dimension.
[0029] In a preferred embodiment, the bifurcation device comprises a body including at least three branches, said branches forming an angle between 45° and 180°.
[0030] Thus, a user can move, without detaching from the belaying system, in many different directions, making it easier to increase the range of movement, while maintaining the user's safety.
[0031] In addition, the presence of at least three branches allows the user to be guided according to the possible directions to be used by the latter.
[0032] In a preferred embodiment, the bifurcation device comprises a plate forming at least three branches, said branches supporting at least on one side of the plate a stop element, said stop element being arranged on the free ends of each of the branches.
[0033] The presence of the stop elements allows the engagement hook to be guided when said engagement hook must slide through the bifurcation device. Indeed, the dimension of the plate and the stop element of the bifurcation device is greater than that of the first cavity of the engagement hook.
[0034] In a particular embodiment, the bifurcation device comprises four branches separated from each other by an angle of 90°, each of the four branches comprising at its free end stop elements.
[0035] In a particular embodiment, the joining device comprises at least two complementary parts, each complementary part is mounted on a free end of a cable system joining with another end of a cable system located nearby, said complementary parts being capable of being coupled together by a rotation of at least a quarter turn.
[0036] Preferably, each of the complementary parts comprises a head including at least one male element and at least one female element, in which each of the male and female elements of each of the complementary parts is intended to cooperate with each other. The female elements comprise a guide groove in which the male elements are intended to be inserted against a cam body. The actuation of the cam body by the movement of the male element in the guide groove is intended to actuate a piston on an elastic return member in order to lock a position in which the complementary parts are connected together, each of the heads of the complementary parts includes at least two fixed projecting elements, arranged opposite each other, on the periphery of the head, each of the complementary parts includes stop elements covering at least partially the head of the complementary parts, said stop elements are mounted to rotate freely around an axis of rotation of the head of each of the complementary parts, said stop elements are intended to fit together in a complementary manner with the projecting elements of the head of each of the complementary parts when the complementary parts are coupled together by a rotation of at least a quarter turn.
[0037] Thus, when the complementary parts are connected together, the protruding elements and the stop elements are aligned with each other so that the joining device has a dimension smaller than the first cavity of the engagement hook, thus allowing the latter to pass through.
[0038] Indeed, when the complementary parts are not connected to each other, the protruding elements and the stop elements are not aligned with each other, so that the stop element also serves as a stop element for the engagement hook, securing the ends of the belaying system.
[0039] Unlocking the position in which the complementary parts are connected together is carried out by the user himself voluntarily, in particular by making a quarter turn in the opposite direction to that of locking the position.
[0040] Thus, when the complementary parts are connected together, the joining device has a smaller dimension than when the complementary parts are not connected together. Consequently, when the complementary parts are not connected together, said complementary parts form a stop element against the engagement hook, securing the cable ends by preventing any unintentional disconnection.
[0041] In a particular embodiment, the joining device comprises three complementary parts. The first and second complementary parts are mounted on the free ends of a cable system connecting to another end of a neighboring cable system. The third complementary part, referred to as the intermediate part, comprises a fixed stop element against which the engagement hook is designed to move and is held in this position by retaining elements mounted for rotation on the head of the third complementary part.
[0042] Thus, the hook can be moved, particularly vertically, without ever being detached from a cable system. Indeed, when joining two cable systems positioned on different floors, each having, on its respective free end, the first and second complementary pieces, the third piece The additional feature allows the engagement hook to remain engaged against the cable system.
[0043] From then on, the change of floor takes place according to a first step in which the user couples, by a rotation of at least a quarter turn between them, the first and the third complementary piece in order to slide the engagement hook of the first piece to the third.
[0044] In a second step the first and third complementary parts are decoupled by a rotation in the opposite direction and the engagement hook is held in position between the fixed stop element and the rotating movable retaining means.
[0045] In a third step, the user changes floors while being insured and couples the third room to the second complementary room in a fourth step.
[0046] Finally, in a fifth and final step, the user decouples the third and second complementary parts in order to engage the engagement hook against the neighboring cable system.
[0047] Preferably, the anchoring device comprises a plate and a matrix including a through groove, into which the cable is intended to be inserted, said plate and matrix being connected to each other by fastening elements.
[0048] The fixing elements allow the cable to be locked in position in the through guide groove, against the plate which provides fixing points for the belaying system against a surface to be climbed or crossed safely.
[0049] In a particular embodiment, the universal continuous belaying system includes a securing device, said securing device includes two matrices of substantially semi-cylindrical shape, having a cavity formed along their length, said matrices are complementary to each other, so that the cavities of each matrix are arranged opposite each other, forming a through guide groove, said matrices include a first end with a diameter smaller than the diameter of a second opposite end.
[0050] Thus, the matrices have a solid arc shape
[0051] More specifically, each matrix has a through groove formed along its length intended to receive a cable of the cable structure.
[0052] In addition, each matrix includes elements for fixing them together in order to realize the securing device, said securing device then has a recess formed by the two through grooves arranged opposite each other, said recess is intended to receive a cable of the cable structure.
[0053] Preferably, the first end of the securing device is provided on a cable of the cable structure so as to be oriented against the direction of user movement. In other words, the first end is the one that will first come into contact with the engagement hook.
[0054] Thus, the first end of the securing device allows for easy sliding of the engagement hook and the second end provides a stop element against the engagement hook, which makes it possible to reinforce the securing of the user, particularly in the event of a fall.
[0055] In addition, and in order to allow increased safety for the user, in particular when installing a universal continuous belay system on a surface with a slope of at least 15°, a safety device is provided every meter on a cable of the cable structure.
[0056] Similarly, for a surface with a slope greater than 30°, a safety device is provided every 0.5 meters on a cable of the cable structure.
[0057] In a particular embodiment, the securing device has a funnel shape.
[0058] In a particular embodiment, the first dimension is greater than the dimensions of the plates of the bifurcation and anchoring devices and less than the dimensions of the plate mounted with the stop element of the bifurcation device and the dimensions of the plate mounted with the matrix of the anchoring device, the second dimension is greater than the dimensions of the plate mounted with the stop element of the bifurcation device and the dimensions of the plate mounted with the matrix of the anchoring device.
[0059] So as to allow the passage of the engagement hook through the bifurcation and anchoring devices and to prevent an unintentional disengagement of said engagement hook.
[0060] Thus, the engagement hook can pass through the bifurcation and anchoring devices without needing to disengage from the cable in order to pass through these devices, which strengthens the safety of the belaying system, because the user is perpetually belayed.
[0061] Of course, the different features, variants and embodiments of the invention can be combined with each other in various ways insofar as they are not incompatible or mutually exclusive.
[0062] In addition, various other features of the invention become apparent from the attached description made with reference to the drawings which illustrate non-limiting embodiments of the invention and where:

[0071] [Fig.9] is a schematic representation viewed from below of a matrix of the device security.
[0072] It should be noted that in these figures the structural and / or functional elements common to the different variants may have the same references.
[0073] Of course, various other modifications can be made to the invention within the scope of the annexed claims.
[0074] With reference to [Fig.1] to [Fig.9], the present invention is a universal continuous belaying system comprising a cable system, an engagement hook, a bifurcation device, several tension anchor devices and a junction device.
[0075] The bifurcation, anchoring and joining devices are fixedly mounted on the cable system 2, the engagement hook 3 is slidably mounted on the cable system 2 and is able to slide continuously along the entire bifurcation 4, anchoring 6 and joining 5 devices.
[0076] The engagement hook 3, shown in [Fig.1], mechanically connects the user to the universal continuous belay system 1 by means of a safety harness and a lanyard.
[0077] The lanyard is attached to the engagement hook 3 on one side by a second cavity 33 of the engagement hook 3 and to the safety harness on the other, by means of a direct link.
[0078] In order to allow the user to move freely in the path established by the cable system 2, the C-shaped body of the engagement hook 3 is designed to engage and attach to a cable 21 of the cable system 2 as well as to the various components of the present invention.
[0079] The C-shaped body includes a first cavity 32, called central, through which a cable 21 of the cable system 2 can pass, thus slidingly engaging the engagement hook 3 with the cable system 2.
[0080] The first cavity 32 has a hexagonal shape with rounded edges, said rounded edges serve as a guide for the engagement hook 3 and allow the engagement hook 3 to adapt to the bifurcation devices 4, tension anchor 6, junction 5 and securing 7 in a secure manner and without risk of slippage.
[0081] The C-shaped body of the engagement hook 3 also includes a socket space 36, said socket space 36 enables the engagement hook 3 to pass through the bifurcation devices 4 and cable tension anchoring devices 6 while being mechanically coupled to the cable system 2 in the event of a user fall.
[0082] The second cavity 33 passes through the C-shaped body and is oriented parallel to the first cavity 32 of the C-shaped body of the engagement hook 3. The second cavity 33 allows the user to connect their safety harness and lanyard to the engagement hook 3, notably via a carabiner. The second cavity 33 is circular in shape to ensure uniform pressure distribution, which extends the service life of the engagement hook 3.
[0083] Thus, the interlocking space 36 of the engagement hook 3 forms a first dimension 38 and the first cavity 32 forms a second dimension 37, said second dimension 37 being larger than the first dimension 38
[0084] A first stud 34 and a second stud 35 are used to prevent the engagement hook 3 from detaching from the bifurcation devices 4, junction device 5, and tension anchor 6. The first stud 34 and the second stud 35 are integrated through the C-shaped body and positioned parallel to the first cavity 32.
[0085] More specifically, the first stud 34 and the second stud 35 are positioned on either side of the interlocking space 36 of the engagement hook 3.
[0086] The universal continuous belay system 1 also includes a bifurcation device 4, shown in [Fig.3], which includes a plate 42 forming a cross-shaped body with four separate arms 41, separated from each other by an angle of 90°, each of the four arms 41 including an attachment hole 44 for a cable 21 of the cable system 2.
[0087] The bifurcation device 4 allows changes of direction within the belaying system 1 and thus allows several users attached to the cable system 2 to cross paths when they are on the same path.
[0088] In addition, the bifurcation device 4 allows a single path of the belaying system to be divided into several paths.
[0089] The cross-shaped bifurcation device 4 connects four cables 21 of the cable system 2 to allow the user access to each of them. For to allow the engagement hook 3 to move freely through the plate 42, the width of the second dimension 37 of the interlocking space 36 of the engagement hook 3 is greater than the thickness of the plate 42 of the bifurcation device 4.
[0090] It is therefore understood that, in order to allow continuous belaying and to prevent the unintentional disengagement of the engagement hook 3 when it slides on the bifurcation device 4, a stop element 43, shown in [Figs. 4 and 5], is arranged on either side of each of the arms 41 of the bifurcation device 4. The assembly, stop element 43 and plate 42, has a thickness greater than the second dimension 37 of the interlocking space 36 of the engagement hook 3 so that the engagement hook 3 locks against the stop elements 43 of the bifurcation device 4.
[0091] Thus, these stop elements 43 provide guideways for the engagement hook 3, which prevents the engagement hook 3 from detaching from the bifurcation device 4 while the user moves the engagement hook 3 from one cable to the other through said bifurcation device 4. The symmetrical design allows the engagement hook 3 to be reversed and to pass through the bifurcation device 4 without risk of decoupling.
[0092] Therefore, to pass the bifurcation device 4 the user simply positions the interlocking space 36 in coincidence with the plate 42 of the cross-shaped body and slides the engagement hook 3 from one arm 41 to another by sliding the stop elements 43 through the first cavity 32 of the engagement hook 3.
[0093] The anchoring device 6, shown in [Fig. 6 to 8], is used to fix a cable 21 of the cable system 2, along a bearing surface of a structure intended to be traversed safely by a user.
[0094] The anchoring device 6 comprises a plate 61 and a matrix 62 comprising a through groove 621 into which the cable 21 is intended to be inserted, said plate 61 and matrix 62 being connected to each other by fastening elements 63.
[0095] The plate 42 includes a protruding element 611 provided with an anchoring hole 612 for attaching the anchoring device 6 to the surface of a support structure on which the user must move safely. The protruding element 611 is oriented perpendicularly to the matrix 62 and to the cable 21 passing through the matrix 62.
[0096] The fastening elements 63 are arranged along the matrix 62 and on either side of the through guide groove 621 allowing a cable 21 to be kept under tension, thus serving to support any user who might fall while crossing the associated path.
[0097] In order to allow the engagement hook 3 to pass through the anchoring device 6, the thickness of the protruding element 611 is less than the first dimension 38 of the engagement hook 3 and the thickness of the die 62 mounted on the plate 61 is greater than said first dimension 38, so as to create a stop to prevent any unintentional disengagement.
[0098] Furthermore, the thickness of the die 62 mounted on the plate 61 is less than the second dimension 37 of the engagement hook 3 so that said hook can slide along the anchoring device 6.
[0099] Thus, to pass the anchoring device 6, the user positions the interlocking space 36 at the level of the protruding element 611 and the first cavity 32 at the level of the matrix 62 and slides the engagement hook 3 until it passes through the matrix 62 of the anchoring device 6.
[0100] In order to connect different cable systems 2, the securing system 1 includes a junction device 5.
[0101] The junction device 5 comprises two complementary parts 51, 52, each of the complementary parts 51, 52 is arranged on a free end of a cable system 2, so as to be able to junction with a complementary part 51, 52 arranged on a free end of another cable system 2 located nearby.
[0102] Said complementary parts 51,52 are coupled together by a rotation of each of the complementary parts 51,52 of a quarter turn.
[0103] Each of the complementary parts 51,52 includes a head 511,521 comprising a male element 512,522 and a female element 513,523 in which each of the male elements 512,522 and female elements 513,523 of each of the complementary parts 51,52 are intended to cooperate with each other.
[0104] The female elements 513,523 include a guide groove 5131,5231 in which the male elements 512,522 are intended to be inserted against a cam body 514, the movement of the male element 512,522 in the guide groove 5131,5231 is intended to actuate a piston 515,525 on an elastic return member 5116,526 in order to lock a position in which the complementary parts 51,52 are connected together.
[0105] Each of the heads 511,521 of the complementary parts 51,52 comprises two first fixed projecting elements 517,527, arranged opposite each other, on the periphery of said head 511,521 of each complementary part 51,52.
[0106] The said supplementary parts 51,52 of each joining device 5 also include two stop elements 518,528 arranged opposite each other, and so as to at least partially cover the head 511,521 of the supplementary parts 51,52.
[0107] Said stop elements 518,528 are mounted to rotate freely around an axis of rotation 519,529 of the head 511,521.
[0108] The stop elements 518,528 are intended to align with the projecting elements 517,527 of the head 511,521, when the quarter turn rotation is performed by a user.
[0109] Thus, the projecting elements 517,527 and the stop 518,528 of the head 511,521 of the complementary parts 51,52 are not aligned only when the complementary parts 51,52 of the joining device 5 are coupled together.
[0110] Thus, in order to allow the engagement hook 3 to pass through the joining device 5, the thickness of the protruding elements 517,527 aligned with the stop elements 518,528 of the head 511,521 of the complementary parts 51,52 is less than the first dimension 38 of the engagement hook 3 and the thickness of the stop elements 518,528 of the complementary parts 51,52, when the latter are not aligned with the protruding elements 517,527 forms a stop, the dimensions of which are greater than those of said first dimension 38, in order to prevent any unintentional disengagement.
[0111] Thus, to pass the anchoring device 6, the user positions the first cavity 32 on one of the complementary parts 51, 52 up to the stop formed by the stop elements 518, 528. The user must then couple the complementary part 51 with another complementary part 52 in order to align the protruding elements 517, 527 and the stop elements 518, 528, reducing the thickness of the joining device 5. Finally, the user must slide the engagement hook 3 until it completely passes through the joining device 5.
[0112] The belaying system 1 also includes a securing device 7 which comprises two matrices 71 of substantially half-cylindrical shape, complementary to each other forming a through guide groove 72.
[0113] The guide groove 72 is arranged in the center of the securing device 7. The dies 71 comprise a first end 73 with a diameter smaller than the diameter of a second opposite end 74, so as to form a securing device 7 having a funnel shape.
[0114] Each of the matrices 71 includes fixing elements 75 between them, in order to realize the securing device 7.
[0115] The securing device 7 then has a recess formed by the two through guide grooves 72 arranged opposite each other, said recess is intended to receive a cable 21 of the cable system 2.
[0116] The securing device 7 is oriented on a cable 21 of the cable system 2, so that the first end 73 is opposite the engagement hook 3, which allows for easy sliding of the engagement hook 3 onto the securing device 7.
[0117] The second end 74 of the securing device 7 makes it possible to create a stop element against the engagement hook 3.
[0118] The preceding description clearly explains how the invention makes it possible to achieve the objectives it has set for itself, namely to improve the safety of users of such a belaying system, in particular by continuous belaying of the user, without requiring disengagement from the cable system.
[0119] In any event, the invention is not limited to the embodiments specifically described in this document, and extends in particular to all equivalent means and to any technically feasible combination of these means
