Belay device and method of use

Abstract

A securing device includes a housing having an opening for a rope loop. A roller (5) is movably inserted into the housing and mounted for free-running. The roller (5) is mounted to move between first, second, and third roller positions. A rotating clamp, depending on the position of the roller (5) in the housing, allows the roller (5) to rotate freely or deactivates one direction of rotation of the roller (5). The rotating clamp allows free rotation of the roller (5) when it is in the first roller position and deactivates one direction of rotation of the roller (5) when it is in the second and third roller positions. A spring (8) biases the roller (5) to the first roller position and converts a force on the roller (5) into a position of the roller in the housing.

Description

[Technical Field]

[0001] This invention relates to a safety device and its method of use. [Previous Technology]

[0002] In mountaineering and other mountain activities, a belaying device is typically used, through which a rope passes to attach the climber. Belaying devices must address two distinct problems. First, they must be easy to use; that is, they must facilitate the movement of the rope within the belaying device to feed slack to the climber or conversely, to quickly tighten slack on the rope. Therefore, a rope channel exhibiting a low degree of friction is necessary.

[0003] When the climber descends and / or experiences auxiliary rope clamping, the safety device must also be secure to provide adjustable braking of the rope. It is also advantageous that the safety device allows for improper handling, and most importantly, it is not so complex as to be unmanageable.

[0004] These two requirements are quite contradictory because, in order to provide adjustable braking or auxiliary rope clamping, it is necessary to have a component in continuous contact with the rope and sufficient friction to detect the rope's operating conditions in the safety device. Therefore, a trade-off must be made between safety and practicality when designing a safety device.

[0005] For example, "tube" type safety devices, such as those sold by the applicant under the trademarks "Reverso®" or "Verso", do not have auxiliary rope clamping or drop detection. The rope must always be held firmly.

[0006] A cam securing device also exists, which has a rotatably mounted cam. The cam pivots between a first position and a second position, in which the rope is clamped between the cam and a clamping area, and in the second position, the distance between the cam and the clamping area is greater than the rope diameter, thereby allowing rope slippage. The rope travels within the securing device and slides along the cam, inducing friction. The shape of the cam and the shape of the rope channel in the securing device define the friction intensity of the rope. To feed the rope to the climber, a certain degree of dexterity must be achieved to prevent the cam from rotating, thereby preventing rope slippage. The friction intensity varies depending on the rope diameter and the degree of rope wear.

[0007] Document US2014 / 0262611 illustrates a configuration of a securing device for a modified cam mechanism. This securing device is a cam securing device, where a portion of the cam is formed by a rotating roller. The roller is mounted to rotate in both directions and has a clamping system when its rotational speed exceeds a critical speed. The angular velocity of the roller represents the linear feed rate of the rope in the securing device. As in other cam mechanisms, the rope slides along the cam and generates friction to actuate the cam when the tension in the rope increases. When the rope moves too fast, the roller becomes blocked, which greatly increases the friction between the rope and the cam and tends to actuate the cam. The device then operates as a cam mechanism. This configuration proves difficult to implement because the coefficient of friction between the rope and the cam varies greatly depending on the rotational speed of the roller, which in turn depends on the frictional force present with the rope. In other words, clamping the rope by means of the cam depends heavily on the shape of the cam, the diameter of the rope, the surface condition of the rope, and the way the roller is integrated into the cam.

[0008] In another technical field, a safety anti-fall device equipped with a rotating roller is known from document FR2149047. The rope passes over the roller, and when the roller's rotational speed reaches its limit, the roller blocks, preventing the rope from advancing. A substantially equivalent instruction is presented in document FR2513886.

[0009] Finally, a roller-based belaying device with a roller in contact with the rope is known. At the climber's request, the roller is mounted to rotate in both directions to avoid obstructing the user during the rope feeding phase. A belaying device sold by Wild Country under the trademark Revo and presented in document US2016 / 0310767 is a belaying device having a rope insertion opening, a rope exit opening, and a wheel that redirects the rope between the insertion and exit openings. A deviation applied to the rope ensures substantial contact between the rope and the wheel. The wheel is associated with a device for clamping the roller when the wheel's rotational angular velocity reaches a critical limit. However, with use, it becomes apparent that descent control is not easy due to the small friction between the rope and the components forming the belaying device. It also becomes apparent that the detection of the descent rate depends heavily on the presence of blockages in the belaying device, particularly at the level of the ratchet that performs wheel clamping. Finally, the belaying device is configured to clamp when a critical velocity corresponding to the fall is reached. In the same way as the "tube" type of securing device, it is impossible to perform a safe static clamping, which may be needed when the climber needs to rest or when the climber is working on the route.

[0010] In another technical field, roller devices are also known as having a brake for rescue operations. Reference document US7,658,264 discloses a roller descender in which the roller rotates only in one direction of rotation. The roller is configured to rotate when the rope is pulled to elevate the injured person and to clamp when the rope is no longer pulled. When the tension on the rope stops, the brake engages to clamp the rope. To lower the injured person's position, a knob must be turned to move the brake, thus allowing the rope to slip. This device is cumbersome and bulky because it is designed for rescue operations. It is not suitable for protecting climbers. In the same technical field, rescue devices having rollers that rotate only in one direction are known from document US7419138. The roller is eccentrically mounted to move toward or away from a pad, such that the rope is caught between the pad and the roller. When the rope is pulled to elevate the injured person, the roller moves away from the pad and the roller rotates itself. When the rope is no longer pulled, the roller clamps, and rotation in the other direction is prohibited. The roller moves toward the pad to clamp the rope. When no force is applied, the roller is in contact with or nearly in contact with the pad. The actuation handle moves the roller and adjusts the rope's slippage between the roller and the clamp. See also document US10828516, which associates a roller with a clamp facing the pad. Again, the roller rotates only in one direction, and the handle moves the clamp to adjust the rope's slippage between the clamp and the pad. [Summary of the Invention]

[0011] One object of the present invention is to remedy these disadvantages, and more specifically, to provide a securing device that can clamp the rope more securely without generating excessive friction with the rope when it is necessary for the climber to tighten the slack portion or to feed the rope to the climber.

[0012] This result tends to be achieved by means of a securing device comprising: - a housing designed to receive a rope loop, the housing defining an attachment point designed to attach the securing device to an anchor point and at least one opening through which strands of the rope loop pass; - a pad defining the at least one opening; - a roller disposed in the housing and mounted to be rotatable in two rotational directions, the roller also mounted to be movable in the housing in a first movement direction between a first roller position, a second roller position and a third roller position, the second roller position being closer to the opening than the first roller position, the third roller position being closer to the pad than the second roller position, the roller being designed to contact the rope loop within at least 40% of its circumference; - A rotary clamp configured to allow the roller to rotate in two rotational directions or prevent rotation in at least one direction of the roller, depending on the position of the roller in the housing; the rotary clamp configured to allow the roller to rotate in two opposite rotational directions when the roller is in the first roller position, and to prevent rotation in at least one direction of the roller when the roller is in the second roller position and the third roller position; a first spring having a first end attached toward the housing and a second end attached to the roller to bias the roller toward the first roller position; the first spring converting a force on the rope loop on the roller into a position of the roller in the housing; a handle assembled to be movable between a first handle position and a second handle position, wherein in the third roller position, the handle is functionally coupled to the housing and the roller such that a force applied to the handle to move the handle generates a force on the roller in the direction of the second roller position.

[0013] According to one feature of the present invention, the roller is provided with a toothed wheel and a hook is mounted on the housing. When the roller is in the second roller position, the toothed wheel contacts the hook, and when the roller is in the first roller position, the toothed wheel is a certain distance away from the hook. The hook and the toothed wheel form the rotating clamp.

[0014] Preferably, the latch is mounted to be movable relative to the housing between a first latch position and a second latch position. When the latch is in the first latch position and the roller is in the second roller position, the toothed wheel contacts the latch. When the latch is in the second latch position and the roller is in the third roller position, the toothed wheel contacts the latch.

[0015] According to another feature, a hook spring applies a force to the hook, and the hook spring places the hook in the first hook position without any applied external force.

[0016] In an advantageous manner, the handle is configured to move the roller to the second roller position such that actuation of the handle does not result in rotation of the roller in both rotational directions.

[0017] It is particularly advantageous that the pad is provided to partially obstruct one of the grooves of the roller when the roller is in the position of the third roller.

[0018] In an advantageous configuration, an additional rotary clamp is configured to prevent the roller from rotating when the roller's rotational speed reaches a threshold value.

[0019] In one preferred development, the roller rotates about a first rotating shaft. The first spring is configured to adjust the space occupied by the rotating shaft perpendicular to the axis of rotation of the roller, and the first spring is configured to apply a force to the rotating shaft and displace the axis of rotation and the roller in the direction of the first roller position.

[0020] Another object of the present invention is to provide a method for using a securing device that is easier to implement than prior art methods. This result is preferably achieved by means of a method for using a securing device comprising the steps of: - setting up a securing device according to any of the aforementioned configurations; - placing a rope loop in the securing device, the rope wrapping around the roller; - setting the tension in the rope below a first threshold value, causing the rope to run in one direction and then in the opposite direction to cause the roller to rotate in one rotational direction and then in another rotational direction; - increasing the tension in the rope until the roller reaches the second roller position, the roller blocking at least one rotational direction; - further increasing the tension in the rope until the rope is clamped.

Implementation Method

[0022] Figures 1 to 18 illustrate different embodiments of the securing device. The securing device is preferably a self-clamping securing device, that is, it is configured to clamp the rope when the stress in the rope inside the securing device exceeds a limit value. Once the rope is clamped, the user must perform a specific action to allow the rope to slide inside the securing device. When the user stops this action, the securing device clamps the rope again when the tension exceeds the limit value.

[0023] Ensure that the device has a housing designed to receive a rope loop. This housing is preferably openable to allow easy insertion of the rope loop. The housing defines at least one opening through which the strands of the rope loop pass. In the illustrated embodiment, the housing defines a single opening, but it is also possible for the housing to define two openings.

[0024] In one particular embodiment, the housing is partially formed by a first flange 1. The first flange 1 is preferably substantially flat. The housing and the first flange 1 preferably define or have an attachment point 2, which is designed to attach a securing device to an anchor point. The anchor point may be a user's seatbelt, but it is possible to use another element to form the anchor point.

[0025] In the illustrated embodiment, the attachment point 2 is formed by a hole that serves as a through-hole inside the first flange 1. A hook or any other type of connector passes through this hole to attach the securing device to the user. The attachment point 2 may also be formed by a connector (e.g., a hook) of the securing device.

[0026] A pad 3 forming the first clamping area is present in the housing and preferentially defines at least one opening of the housing. In the illustrated embodiment, the pad 3 extends projectingly from the first surface 1a of the first flange 1 in a first direction. The first direction is perpendicular to or substantially perpendicular to the first surface 1a to form the projecting area. The pad 3 is designed to clamp the rope in the securing device. According to a preferred embodiment, the pad 3 is formed together with the remainder of the first flange 1, or the pad 3 is fixed to the first flange 1. The pad 3 can be fastened to the first flange 1 by means of a nut 3a.

[0027] Preferably, the housing has a second flange 4 that is mounted to be movable and / or removable relative to the first flange 1, which makes it easier to insert a rope. The second flange 4 closes the space designed to receive the rope and partially defines the opening.

[0028] The securing device has rollers 5 that exhibit two opposing movements within the housing. On one hand, the rollers 5 are mounted to idle, i.e., they rotate in two opposite directions of rotation. The rollers 5 are mounted to rotate about a first rotating shaft 6 that defines a first axis of rotation. The first axis of rotation of the rollers 5 passes through the center of the rollers 5. When a rope loop is installed in the securing device, the rope wraps around the rollers 5 such that the rope contacts the groove of the rollers 5. The distance by which the rope wraps around the rollers 5 and contacts the rollers 5 is equal to at least one-quarter of the perimeter, more preferably at least one-third of the perimeter, and more preferably at least 40% or at least half of the perimeter. Advantageously, the diameter of the rollers 5 is greater than or equal to half the distance separating the two separators 7, more preferably at least equal to 70% of the distance separating the two separators 7, and even more preferably greater than the distance separating the two separators 7.

[0029] It is particularly advantageous to enable the roller 5 to move in two opposite directions of rotation, as this facilitates the operation of the rope within the securing device during the two phases of rope operation, to feed the rope to the climber or conversely to slack the rope with low friction.

[0030] On the other hand, the roller 5 is movably mounted in the housing to move toward or away from the opening and / or the gasket 3. In other words, the first rotating shaft 6 is movably mounted in the housing to move toward or away from the opening. The axis of rotation of the roller 5 is displaced relative to the first flange 1.

[0031] The opening of the housing is fixed to the housing and defined by two delimiters 7, one of which is preferably formed by a pad 3. The rope loop leaves the securing device, thereby pressing against the two delimiters 7 and passing over the roller 5.

[0032] The roller 5 is mounted to be movable so that it can move inside the housing in addition to rotating. The roller 5 is mounted to be movable so that it can move between several positions. In a first direction of movement, the roller 5 moves between a first roller position, a second roller position, and a third roller position. The second roller position is located between the first roller position and the third roller position. The second roller position is closer to the opening than the first roller position and can be closer to the gasket 3 than the first roller position. The third roller position is closer to the gasket 3 than the second roller position and can be closer to the opening than the second roller position.

[0033] The device is equipped with a rotary clamp configured to allow the roller 5 to rotate in two rotational directions or block at least one of the two rotational directions, depending on the position of the roller 5 inside the housing. In one specific configuration, the rotary clamp is configured to allow rotation in two rotational directions or only in one rotational direction, depending on the position of the roller 5 inside the housing. In another specific configuration, the rotary clamp is configured to allow rotation in two rotational directions or block rotation in both rotational directions, depending on the position of the roller 5 inside the housing. The rotary clamp is fixed to the housing.

[0034] The rotary fixture is configured to allow roller 5 to rotate in two opposite directions when roller 5 is in the first roller position. The rotary fixture is configured to allow roller 5 to rotate in only one direction or prevent rotation when roller 5 is in the second roller position. The rotary fixture is configured to allow roller 5 to rotate in only one direction or prevent rotation when roller 5 is in the third roller position.

[0035] The rotating clamp for the roller can be formed in any suitable manner. Depending on the configuration, the rotating clamp can function by clamping the roller 5 and / or by clamping the rotating shaft 6 of the roller 5. The rotating clamp has a stop attached to the housing to prevent rotation of the roller 5. When the roller 5 is in the second stop position and when the roller 5 is in the third stop position, the roller 5 and / or the first rotating shaft 6 rest on the stop. Depending on the configuration, the stop directly prevents rotation of the roller or the first rotating shaft. The stop can be fixedly or movably mounted relative to the housing.

[0036] The device ensures that it has a first spring 8, which connects the roller 5 and the housing, preferably the first spring 8 connecting the roller 5 and the flange 1. The first spring 8 is formed by one or more elastically deformable parts. The first spring 8 biases the roller 5 so as to place the roller 5 in a first roller position without external force being applied. The first spring 8 is configured to resist movement of the roller 5 from the first roller position to a second roller position or a third roller position. The first spring 8 transforms a predefined force applied to the roller 5 in the opening direction into a predefined position in the housing. The first spring 8 transforms the tension in the rope and thus the force applied to the roller 5 into the position of the roller inside the housing.

[0037] The first spring 8 and the rotating clamp together form a clamping system configured to prevent the roller 5 from rotating based on the force applied to the roller 5 in the direction of the opening. Tension in the ropes within the securing device causes the ropes to exert a force on the roller 5. Depending on the value of the force applied to the roller by the ropes, the roller 5 moves, thereby allowing the roller to rotate in two directions of rotation or blocking at least one direction of rotation. The first spring 8 associated with the rotating clamp enables the behavior of the roller 5 to be modified based on its position within the housing and therefore based on the force applied to it.

[0038] As the force applied to roller 5 gradually increases and resists the force applied by the first spring 8, roller 5 moves from the first roller position to the second roller position and then to the third roller position. When roller 5 is subjected to a force below a first threshold value, roller 5 is in the first roller position. When the force applied to roller 5 increases and reaches the first threshold value, roller 5 reaches the second roller position. If the force increases further, roller 5 moves until it reaches the third roller position.

[0039] Preferably, a first spring 8 defines a mechanical connection between the roller 5 and the first flange 1. The first spring 8 enables the definition of a first force limit value. The first spring 8 may be directly connected to the first flange 1 and the roller 5, or preferably to the rotating shaft 6 of the roller 5. However, it is also possible to provide one or more intermediate portions in the mechanical connection between the roller 5 and the housing or the first flange 1. For example, the first spring 8 may be fixed to the first flange 1 on one side and to an intermediate portion on the other side, which is itself connected to the roller 5, or the first spring 8 may be fixed to the roller 5 on one side and to an intermediate portion on the other side, which is fixed to the first flange 1. The first spring 8 may be formed in any suitable manner, such as a torsion, compression, tension, or flexure spring. The first spring 8 may be a helical spring or a leaf spring.

[0040] When roller 5 is in the first roller position, corresponding to a weak force and therefore a weak tension applied by the rope, roller 5 can rotate in both directions of rotation. This configuration allows the rope to easily move in both directions. As the tension in the rope gradually increases, roller 5 moves toward the opening until it reaches the second roller position. When the roller reaches the second roller position, roller 5 may no longer rotate in both directions. Roller 5 may rotate in only one direction or may not rotate at all. Blocking the roller in at least one of the rotation directions increases the friction between the rope and roller 5. Increased friction between the rope and roller 5 enhances the sensitivity of roller 5 to the behavior of the rope. Small changes in tension in the rope are better sensed by roller 5, thereby helping the rope to be clamped by ensuring the device is secure.

[0041] Due to the action of the force exerted on the roller 5 by the rope, the axis of rotation, and more generally the roller 5, moves relative to the first flange 1. The greater the force present in the rope, the greater the force exerted on the roller 5, thereby pulling the roller toward the opening and toward the pad. The movement of the roller 5 tends to reduce the available space for the rope strands to pass through.

[0042] Once the second roller position is reached, roller 5 may be able to rotate only in the direction corresponding to the climber tightening the rope, or may not rotate at all. Roller 5 can rotate to allow the climber to easily tighten the rope, thereby improving safety. On the other hand, the roller cannot rotate in the direction that feeds the rope to the climber, meaning that the rope can remain clamped and promote rope locking and even self-locking.

[0043] The third roller is positioned closer to the pad 3 than the second roller. As the roller 5 moves toward the pad 3, the space available for the rope strands to be attached to the climber decreases, increasing friction until the rope is clamped. The reduced available space increases the friction between the rope and the roller 5, making the roller more sensitive to the tension in the rope.

[0044] To facilitate the operation of the rope within the securing device, the rope preferably contacts the minimum number of components forming the securing device. For example, the rope contacts only the roller 5 and the two delimiters 7 that form the two outgoing contact points of the rope. Preferably, the securing device does not have a locking cam that is in continuous contact with the rope. This locking cam introduces considerable friction on the rope, which complicates the use of the securing device.

[0045] A force applied to the roller 5 causes the roller 5 to move within the housing and alters its behavior. The position of the roller 5 within the housing is defined by the force applied to the roller 5. Blocking the roller 5 in one rotational direction ensures sufficient friction between the roller 5 and the rope to achieve rope clamping. The device ensures that a rope clamp 10 is movably mounted within the housing. The rope clamp 10 moves toward or away from the pad 3 relative to the pad 3. In one position, the rope clamp 10 is quite close to the pad 3 to clamp the rope between the pad 3 and the rope clamp 10. The rope clamp 10 is functionally attached to the roller 5 such that the position of the rope clamp 10 follows the position of the roller 5, and vice versa, between a second roller position and a third roller position.

[0046] Different configurations of the rope clamp 10 are possible. In the embodiments of Figures 1 to 7, the roller 5 forms the rope clamp 10. In the embodiments of Figures 8 to 18, the rope clamp 10 is formed by an additional pad. In the second roller position, the roller 5 reaches a stop that mechanically connects the rope clamp 10 to the roller, such that movement of the roller 5 between the second roller position and the third roller position causes movement of the rope clamp 10. Preferably, when the roller 5 is between the second roller position and the third roller position, the position of the roller and the position of the rope clamp are connected in a bi-firing manner.

[0047] In the specific conditions illustrated in Figures 8 to 18, the roller 5 moves until it contacts the rope clamp 10. When the roller 5 reaches the stop on the rope clamp 10, the roller 5 is in the second roller position. The movement of the roller 5 from the second roller position to the third roller position causes the rope clamp 10 to move in the direction of the pad 3, thereby reducing the distance between the pad 3 and the rope clamp 10 until the rope is clamped.

[0048] The device includes a handle 9 that is functionally connected to the roller 5 and the rope clamp 10. The handle 9 can be directly connected to the rope clamp 10 or connected to the roller 5. The handle 9 is movable between a first handle position and a second handle position. When the roller 5 is in the third roller position, corresponding to the minimum distance between the rope clamp 10 and the pad 3, rotation of the handle 9 causes the rope clamp 10 to move away from the pad 3.

[0049] The mechanical connection between the handle 9 and the roller 5 means that the force applied to the handle 9 to rotate the roller 5 in the first rotational direction of the handle will generate a force on the roller 5, thereby moving the roller 5 away from the third roller position to the second roller position. The force applied to the handle 9 causes the rope clamp 10 to move away from the pad 3. The rope will be able to slide between the rope clamp 10 and the pad 3.

[0050] In the examples illustrated in Figures 9 to 18, the handle 9 has a mechanical connection to the first flange 1 and to the rope clamp 10 to allow the rope clamp 10 to move relative to the pad 3. Depending on the embodiment, the handle 9 may be mounted on the first flange 1, on the rope clamp 10, or on an intermediate portion connected to the first flange 1 and the rope clamp 10 or connected to another part of the housing. Many configurations are possible.

[0051] Particularly advantageously, the actuation of the handle 9 does not allow the roller 5 to move beyond the second roller position in the direction of movement opposite to the first direction of movement, so as to prevent the roller 5 from reaching the first roller position and allow the roller 5 to rotate freely.

[0052] As indicated above, the securing device allows the roller 5 to rotate in two rotational directions, or only in one direction, or even prevents any rotation, depending on the position of the roller 5 relative to the first flange 1. The position of the roller 5 relative to the first flange 1 is defined by the force applied to the roller 5. This configuration is not present in the prior art. This configuration enables the rope to be clamped independently of the rope feed rate and independently of the rope feed direction.

[0053] Document US2014 / 0262611 does not disclose the relationship between the tension in the rope and the clamping of roller 5, or the relationship between the force applied to roller 5 and thus to the cam and the clamping of roller 5. According to document US2014 / 0262611, the rotation or clamping of the cam only occurs when the rope is running too fast in a configuration corresponding to a fall. The same conclusion can be reached regarding the securing device sold by Wild Country under the trademark Revo. The clamping of the rope depends on the rotational speed of roller 5 and is independent of the tension present in the rope.

[0054] In an advantageous manner, to better detect whether a climber has fallen, the device is equipped with an additional rotating clamp configured to stop the roller from rotating when the roller's rotational speed reaches a critical limit. This additional stop is only related to the rotational speed and is independent of the force applied to the roller.

[0055] This result may be obtained in different embodiments. In one particular embodiment illustrated in Figures 1 to 7, the rope clamp 10 is formed by rollers 5. The position of the first roller is illustrated in Figure 1. As indicated above, when there is low tension in the rope, roller 5 can rotate in both directions, meaning that the rope can easily run in both directions. When roller 5 is subjected to a higher force corresponding to a first threshold value, roller 5 moves and reaches the second roller position illustrated in Figure 2. Roller 5 is allowed to rotate only in one direction of rotation. Roller 5 can rotate to tighten the rope from the climber.

[0056] When the roller 5 is subjected to a force higher than the first limit value, the roller 5 reaches the third roller position 5, which is closer to the pad 3. In the third roller position, the roller 5 and the pad 3 can clamp the rope installed in the securing device.

[0057] In an advantageous embodiment, such as the one illustrated in Figures 4 and 5, the roller 5 also has a detector configured to detect the rotational speed of the roller 5, which preferably forms an additional rotary clamp. These detectors are configured to prevent the roller 5 from rotating when its rotational speed reaches a critical speed limit. The additional rotary clamp may have a movably mounted latch 11 and a protruding pin 12. The latch 11 is mounted to move between a position where the latch 11 is pushed down, allowing the roller 5 to rotate, and a position where the latch 11 is pulled out, preventing the roller 5 from rotating. The latch 11 may be associated with a latch spring 11a that biases the latch 11 to the pushed-down position and defines the force to be overcome, i.e., the minimum rotational speed, thereby pulling the latch 11 out. Once the latch 11 is pulled out, it contacts the pin 12 that clamps the roller 5. The latch 11 can be pressed against the first rotating shaft 6 in the pulled-out position to prevent rotation of the roller 5, the first rotating shaft 6 being fixedly mounted. Figure 4 illustrates the latch 11 in the pushed-down position, and Figure 5 illustrates the latch 11 in the pulled-out position. The latch 11 is advantageously mounted to be rotatable about a latch shaft 11b, for example, formed by a screw. Other embodiments of additional rotating clamps are possible. When the rotational speed reaches a threshold speed corresponding to a threshold centrifugal force, the latch 11 moves from the pushed-down position to the pulled-out position. It is advantageous to use a spring that defines the value of the threshold force and thus the threshold rotational speed. This spring counteracts the centrifugal force.

[0058] Using an additional rotating clamp helps detect the rapid movement of the rope and reduces the risk of injury.

[0059] Advantageously, in the embodiments illustrated in Figures 1 to 7, the roller 5 rotates about the first rotating shaft 6, and the first spring 8 is configured to apply a force to the first rotating shaft 6 and move the first rotating shaft 6 and the roller 5 in the direction of the first roller position. In the absence of any bias, the first spring 8 applies a force to the first rotating shaft 6 such that the roller 5 is in the first roller position.

[0060] In a preferred manner and as illustrated in FIG. 6, a first rotating shaft 6 is fixed to a support 13 mounted to be movable relative to a first flange 1. A first spring 8 is configured to apply force to the support 13 to move the roller 5 in the direction of the first roller position. In the particular example illustrated, the support 13 is mounted to be rotatably movable, but another movement is possible. In the illustrated configuration, the support 13 is mounted to be rotatably movable about a support rotating shaft 14 fixed to the first flange 1. The first spring 8 is fixed to the first flange 1 on one hand and to the support 13 on the other hand and applies force to the support 13 to position the roller 5 in the first roller position.

[0061] Advantageously, the support member 13 is separated from the roller 5 by the first flange 1. The first rotating shaft 6 is fixed to the support member 13 and passes through the aperture 1c of the first flange 1. Preferably, the aperture 1c is configured such that when the roller 5 is in the first roller position, the first rotating shaft 6 presses against one end of the aperture 1c, and when the roller 5 is in the third roller position, the first rotating shaft 6 presses against the opposite end of the aperture 1c. It is also preferable that the aperture 1c is always completely covered by the roller 5.

[0062] The supporting rotating shaft 14 can also form the axis of rotation of the second flange 4 relative to the first flange 1. The supporting rotating shaft 14 can also be used to fix the cover 15 to the second surface 1b of the first flange 1 for the purpose of protecting the support 13.

[0063] The supporting rotating shaft 14 may further serve as a rotating shaft for forming additional rollers of the guide 7 opposite to the pad 3. The supporting rotating shaft 14 may cooperate with the nut 14a to secure the supporting rotating shaft 14 to the first flange 1.

[0064] It is also advantageous that the roller 5 is mounted on a bearing 16, such as a ball bearing or other bearing, to facilitate rotation of the roller 5 about the first rotating shaft 6. In the embodiment illustrated in FIG. 6, the handle 9 is mounted to rotate about a third rotating shaft 17 fixed to the first flange 1. The handle 9 is fixed to the first flange 1 by means of a nut 18. The handle 9 slides along the ramp of the support 13 to move the support 13 and thus move the roller 5. The actuation of the handle 9 is for the distance between the roller 5 and the pad 3, and does not act to obstruct the roller 5 in at least one of the two directions of rotation.

[0065] In the advantageous embodiment illustrated in Figures 1 to 7, the roller 5 is provided with a toothed wheel 19 and a latch 20 is mounted on the first flange 1. When the roller 5 is in the second roller position, the toothed wheel 19 is in contact with the latch 20. When the roller 5 is in the first roller position, the toothed wheel 19 and the latch 20 are separated by a certain distance. In the illustrated embodiment, the contact between the latch 20 and the toothed wheel 19 only allows the roller 5 to rotate in one direction of rotation. No contact between the toothed wheel 19 and the latch 20 would allow the roller 5 to rotate in two directions of rotation. By modifying the shape of the teeth of the toothed wheel 19 and by modifying the shape of the latch 20, it is possible to prevent the roller 5 from rotating in two directions. The use of the toothed wheel 19 associated with the latch 20 is particularly advantageous because it is easy to achieve and its operation is robust.

[0066] To form a rotary clamp, many other configurations are possible, depending on the position of the roller 5, such that the roller 5 can rotate in two rotational directions or prevent rotation in at least one direction. It is possible to mount the roller 5 so that it can rotate only in the first rotational direction about the first rotating shaft 6, and to mount the first rotating shaft 6 so that it can rotate in a second direction or in both rotational directions. Movement of the roller 5 corresponds to movement of the first rotating shaft 6. When the roller 5 reaches the second roller position, the first rotating shaft 6 only clamps, thus allowing the roller 5 to rotate in the first rotational direction. For example, if the first rotating shaft 6 is mounted on the support 13, as illustrated in FIG5, it is possible to use a first rotating shaft 6 with a non-circular cross-section and an aperture 1c that prevents rotation of the first rotating shaft 6 when the second roller position is reached. The aperture 1c can be replaced by a hook that grips the first rotating shaft 6.

[0067] When the roller 5 is equipped with the toothed wheel 19, it is particularly advantageous to mount the hook 20 on the first flange 1 and preferably mount the hook 20 so as to follow the movement of the roller 5 beyond the second roller position. When the roller 5 is in the second roller position and until it reaches the third roller position, the toothed wheel 19 is in contact with the hook 20. When the roller 5 is in the first roller position, the toothed wheel 19 is a certain distance away from the hook 20. The stop 21 prevents the hook 20 from still contacting the toothed wheel 19 when it has passed beyond the second roller position. The contact between the hook 20 and the toothed wheel 19 allows the roller 5 to rotate in only one rotational direction. In the illustrated example, the hook 20 forms a through hole, and the stop 21 passes through the through hole to define the amplitude of the movement of the hook 20. Other configurations of the stop are possible. Preferably, the hook 20 is mounted to be rotatable.

[0068] Preferably, the latch 20 is mounted to be movable relative to the first flange 1 between a first latch position and a second latch position. When the latch 20 is in the first latch position and the roller 5 is in the second roller position, the toothed wheel 19 contacts the latch 20. When the latch 20 is in the second latch position and the roller 5 is in the third roller position, the toothed wheel 19 contacts the latch 20. Movement of the roller 5 between the second and third roller positions causes movement of the latch 20, which remains in contact with the toothed wheel 19 to prevent the roller 5 from rotating in at least one of the two rotational directions. Preferably, actuation of the handle 9 does not modify the contact between the latch 20 and the toothed wheel 19.

[0069] It is advantageous to provide a spring 22 (referred to as a hook spring) that applies force to the hook 20. The hook spring 22 positions the hook 20 in the first hook position without applying any external force. In the embodiment illustrated in Figures 1 to 7, and more specifically in the embodiment illustrated in Figure 6, it can be noted that the housing is formed by a first flange 1 on which a frame 23 is mounted. The frame 23 separates the first flange 1 from the second flange 4 and partially defines the housing. The latch 11 is mounted to be rotatable about a latch rotation shaft 11b fixed to the roller 5.

[0070] The embodiments illustrated in Figures 1 to 7 have a simple movement of roller 5, which is mounted to allow simple rotation about the support rotation axis 14. The embodiments in Figures 8 to 15 present the same or substantially the same operation as the roller 5 moving relative to the support 13 and the support 13 moving relative to the first flange 1.

[0071] Figures 8 to 15 illustrate roller 5, which is clamped on rope clamp 10, but it is possible to prevent the rotation of roller 5 by using hooks or equivalent components.

[0072] Figure 15 illustrates an embodiment in which the roller 5 is mounted to rotate about a first rotating shaft 6. The first rotating shaft 6 is mounted to rotate about a second rotating shaft, which is formed here by a supporting rotating shaft 14. The first rotating shaft 6 is mounted to move between a first roller position and a second roller position.

[0073] The support member 13 equipped with the rope clamp 10 is mounted so as to be rotatable about the support rotating shaft 14. The first rotating shaft 6 is connected to the support member 13 by means of a first spring 8. The first spring 8 is connected to the support member 13 on one side and to the first rotating shaft 6 on the other side. The spring 8 is configured to apply a force that biases the first rotating shaft 6 and thus biases the roller 5 to the first roller position 5.

[0074] As illustrated in Figures 10 and 11, a force applied to the roller 5 in the direction of the opening, such as that achievable by a stretched rope loop, causes the roller 5 to move within the housing and relative to the support 13. The roller 5 moves until it abuts against a stop formed by the rope clamp 10. As the force on the roller 5 increases, the support 13 rotates, thereby having the effect of moving the rope clamp 10 toward the pad 3 to clamp the rope. Preferably, the spring 8 has a lower stiffness than the spring 26, so that when the roller 5 is subjected to force in the direction of the opening, the roller 5 moves more than the support 13. The stiffness values ​​and configurations of the springs 8 and 26 can be adjusted depending on the required movement of the support 13 and the roller 5. It is also possible to specify that the rotating shaft of the roller 5 is different from the rotating shaft of the support 13.

[0075] In the embodiment illustrated in FIG. 15, the support member 13 has a protruding pin 28 that is inserted into the first rotating shaft 6. A spring 8 presses against the pin 28. The first spring 8 applies a force designed to press the first rotating shaft 6 against the stop 29 of the support member 13 to define the position of the first roller. This embodiment is simple and efficient to implement for determining the clamping of the trigger roller and the rotation of the support member 13 to adjust the critical tension of the friction on the rope by means of a rope clamp.

[0076] In another embodiment, the movement of the roller 5 between the first roller position and the second roller position is achieved by means of a first rotating shaft 6 having a variable space occupation or a rotating shaft mounted to be movable relative to the support 13. An exemplary embodiment of a rotating shaft having a variable space occupation is illustrated in Figures 16 to 18. The first rotating shaft 6 has a main portion 6a and a secondary portion 6b. The secondary portion 6b is mounted to be movable relative to the main portion 6a between a first position and a second position. In the first position illustrated in Figure 17, the secondary portion 6b extends protrudingly from the main portion 6a by a first distance. The first rotating shaft 6 has a first space occupation value substantially corresponding to a first apparent diameter. In the second position illustrated in Figure 18, the secondary portion 6b extends protrudingly from the main portion 6a by a second distance. The second distance is less than the first distance, such that the first rotating shaft 6 has a second space occupation value substantially corresponding to a second apparent diameter. The second space occupation and the second apparent diameter are less than the first space occupation and the first apparent diameter. Figure 18 illustrates a configuration where the secondary part 6b no longer protrudes from the main part and occupies minimal space.

[0077] The spring 8 biases the secondary portion 6b in the direction of the first roller position, maximizing the space occupied by the first rotating shaft 6. As the force applied to the roller 5 gradually increases, the spring 8 deforms and reduces the space occupied by the first rotating shaft 6. As the space occupied by the first rotating shaft 6 decreases, the roller 5 moves until it reaches the second roller position. In the second roller position, the roller 5, which was capable of rotating in two rotational directions, becomes capable of rotating only in a single rotational direction.

[0078] To achieve clamping of the roller 5 according to its position within the housing, it is possible to specify that a portion of the first rotating shaft 6 has at least one shaft tooth 24 that engages with the roller teeth. The roller 5 has one or more roller teeth 25. In the first roller position 5, at least one shaft tooth 24 does not contact the roller teeth 25 when the secondary portion 6b presses against the roller 5 to prevent contact between the teeth 24 and 25. In the second roller position, the secondary portion 6b retracts and at least one roller tooth 25 contacts the shaft tooth 24. When the roller is designed to rotate only in one direction in the second roller position, for example, the orientation of the triangular teeth allows for the definition of the permissible direction of rotation and the prevented direction of rotation.

[0079] As indicated above, it is possible to provide a roller 5 that is mounted to be rotatable about a first rotating shaft 6 in only one rotational direction. The first rotating shaft 6 is mounted to be rotatable to allow the roller 5 to rotate in both directions. When the roller 5 reaches the second roller position, the secondary portion 6b prevents rotation about the first rotating shaft 6, and the roller 5 can rotate in only one direction. At least one elastic member 8 mounted in the first rotating shaft defines a first force limit value.

[0080] The first rotating shaft 6 can be mounted on a support 13 that is the same as or substantially the same as the support in FIG. 6, which is connected to the first flange 1 by a second spring 26. The second spring 26 is selected to have a greater stiffness than the first spring 8, such that the roller 5 is allowed to rotate only in a single rotational direction before clamping the rope onto the first clamping area 3. The handle 9 can be configured the same as previously described.

[0081] In a preferred manner, the movement of roller 5 relative to the deformable rotating shaft is stopped by means of a roller stop. When the roller stop contacts roller 5, friction is generated, thereby releasing the stress on the tooth configuration and resulting in rotation in only one direction. In the specific embodiments illustrated in Figures 8 to 18, rope clamp 10 forms the roller stop. In the embodiments illustrated in Figures 8 to 18, rope clamp 10 is different from roller 5.

[0082] In the previous embodiment, the roller 5 is mounted to move between a first roller position that allows rotation in two directions and a second roller position that prevents rotation in at least one rotational direction. In the second roller position and the third roller position, the roller 5 cannot rotate in the direction of feeding the rope to the climber. The friction with the rope increases relative to the rotating roller, which facilitates the transmission of rope force to the roller 5 and thus to the rope clamp 10 to clamp the rope onto the pad 3.

[0083] The roller 5 and the rope clamp 10 are mounted on the support member 13. The support member 13 is mounted to be movable within the housing, preferably movable relative to the first flange 1. Preferably, the rope clamp 10 is fixedly mounted on the support member 13. Preferably, the support member 13 is mounted to be rotatable about a support shaft 14 fixed to the first flange 1. The roller 5 is eccentric relative to the support shaft 14, such that the force applied to the roller 5 causes the support member 13 to rotate and causes the rope clamp 10 to move toward the pad 3. The second flange 4 can be mounted to be rotatable on the flange rotation shaft 27.

[0084] Advantageously, the support spring 26 is connected to the first flange 1 on one side and to the support member 13 on the other. The support spring 26 is configured to bias the rope clamp 10 away from the pad 3. In other words, the support spring 26 resists movement that would cause the rope clamp 10 and the pad 3 to move toward each other. The stiffness of the support spring 26 is greater than that of the first spring 8, such that the rope clamp 10 allows the rope to slip between the rope clamp 10 and the pad 3 before the roller 5 leaves the second roller position. In other words, when sufficient force is applied to the roller 5, the roller 5 prevents rotation in one of the rotational directions before the clamp 10 clamps the rope in the first clamping area 3.

[0085] In the embodiments illustrated in Figures 9 to 18, the first rotating shaft 6 of the roller 5 is eccentrically mounted relative to the support shaft 14, which fastens the first rotating shaft 6 to the support 13. Advantageously, a first rotating shaft 6 with variable space occupation, such as the first rotating shaft shown in Figures 16 to 18, is used. As explained above, the greater the force applied to the roller 5, the more the roller 5 moves from the first roller position to the second roller position. In the second roller position, rotation in at least one of the rotational directions is prevented, which would generate strong friction between the rope and the roller 5. When the roller 5 cannot rotate, the force applied to the roller 5 causes the roller 5 to move, and thus causes the support 13 and the rope clamp 10 to move. Where applicable, the movement of the rope clamp 10 results in movement toward the pad 3 and clamping of the rope.

[0086] In the embodiment illustrated in FIG. 9, the support member 13 is mounted to be movable relative to the first flange 1, and the support member 13 is mounted on the first flange 1. A roller 5 is mounted on the support member 13. The roller 5 is fixed to the first flange 1 by means of the support member 13. A clamp 10 is fixedly mounted on the support member 13. The movement of the clamp 10 follows the movement of the support member 13, and vice versa.

[0087] As indicated above, the handle 9 has a mechanical connection to the first flange 1 and the roller 5, for example, via the support 13 and / or the first rotating shaft 6. During rotation of the handle 9, the force applied to the handle 9 applies a force between the roller 5 and the housing, thereby moving the rope clamp 10 away from the pad 3. In a particular illustrated embodiment, the handle 9 is mounted on the support 13, and preferably, the handle 9 is mounted to be rotatable about the handle rotating shaft 17, thereby advantageously cooperating with the screw 17a to secure the handle rotating shaft 17 to the support 13. Alternatively, the handle 9 may be mounted on the first flange 1 or another component. The handle 9 may be biased to a first handle position by means of a handle spring 30.

[0088] Figure 10 illustrates the roller 5 in the first roller position and the rope clamp 10 in the first clamping position. The rope can run in both directions, and the roller 5 facilitates this running by rotating in both directions to follow the rope. The rope is not stretched. As the tensile load in the rope increases, the force on the roller 5 increases until it reaches a first threshold value. The roller 5 moves to a second roller position that blocks at least one direction of rotation, as illustrated in Figure 11. Preferably, the roller 5 presses against the roller stop. As the force on the roller 5 increases, the support 13 displaces the rope clamp 10 in the direction of the pad 3, which ensures rope clamping. Actuation of the handle 9 displaces the support 13 to move the support 13 away from the pad 3 and achieves rope sliding.

[0089] In the illustrated embodiment, the roller 5 is mounted to rotate about a first axis of rotation that is perpendicular or substantially perpendicular to the first surface 1a of the first flange 1. In operation, the rope moves within a rope travel channel. The rope travel channel is configured such that the rope presses against two deflectors 7 fixed to either the first flange 1 or the second flange 4. The deflectors 7 are separated by the roller 5 along the rope's travel path. When the rope is stretched, it presses against the deflectors 7 and the roller 5, applying force to the roller 5 and thus pushing it to the second roller position.

[0090] In the illustrated embodiment, the handle 9 is designed to be actuated by the left hand. The rope strands that must exit through the right-side aperture are designed to be attached to the climber and correspond to the uphill route strands. The rope strands that must exit through the left-side aperture are designed to feed or tighten excess rope. A reverse configuration for the securing device used to actuate the handle 9 with the right hand is possible.

[0091] In the illustrated embodiment, the attachment point 2 is located below the roller 5. However, it is also possible to have an attachment point 2 that passes through the roller 5, which therefore has a hole. However, this embodiment is less advantageous because it requires a larger connector to secure the device to the attachment point. Advantageously, the attachment point is located in the second flange 4 so that the connector closes the securing device.

[0092] Particularly advantageous is the ability of roller 5 to rotate in the first rotational direction even when the rope is clamped. This makes it easier to tighten the slack portion of the rope to assist the climber without compromising safety. For comparative purposes, when the securing device detects the rotational speed of roller 5 and blocks it, once roller 5 is blocked and the rope is tensioned, the user is unaware whether their next action on the securing device will result in releasing the blockage of roller 5, and therefore may mean that the climber will fall again under improper handling, even though the rope is tensioned.

[0093] The method of using the securing device is as follows. A rope loop is placed in the securing device, the rope wrapping around the roller 5. Because the tension in the rope is below a first threshold, the roller 5 is in the first roller position. The rope travels in one direction and then in the opposite direction, causing the roller 5 to rotate in one rotational direction and then in another rotational direction. The tension in the rope increases inside the securing device and applies a force to the roller 5 in the direction pointing towards the opening of the housing. The roller 5 moves until it reaches the second roller position. The rope travels in the climber's direction without causing the roller 5 to rotate about its axis of rotation. The increased tension in the rope causes the roller 5 to move to the third roller position and the rope clamps.

[0094] Rotation of handle 9 allows rope clamp 10 to move relative to pad 3, and roller 5 is clamped in at least one rotational direction. The movement of rope clamp 10 relative to pad 3 modulates the separation distance and thus modulates the friction present between the rope, rope clamp 10, pad 3 and roller 5 to modulate the rope feed rate.

[0095] When the tension in the rope reaches a critical value, the device ensures that the roller stops rotating. When the roller 5 separates from the rest position by a critical distance, the device ensures that the roller 5 stops rotating. The rest position is the position where the rope has no tensile load. The first spring transforms the tensile load in the rope into the position of the roller in the housing, and thus into the distance of the roller from the rest position.
