    [0001] The invention relates to a hauling device. State of the art In mountaineering, when one of the companions has fallen into a crevasse, or more generally when an individual is stuck on a strand of rope, it is important to be able to lift the person in distress in order to improve his safety. situation. The techniques of hauling are commonly used because they allow to increase the applied force which allows to lift a large mass in a not always suitable environment. The hauling technique commonly uses one or more pulleys that allow a force return and a self-locking device to facilitate maneuvering.
    [0002] This situation happens very rarely, but it is particularly stressful. In fact, this situation happens unexpectedly (fall in crevasse, accident) and the person who must rescue the individual in distress must simultaneously ensure his own safety and save his energy in order to avoid a worsening of the situation. In these extraordinary situations, it is not uncommon for the person to be rescued to be injured or even unconscious, which makes them unable to intervene in their own rescue. It is therefore necessary that the person providing the rescue has a perfect mastery of the hauling technique and also enough calm to handle this situation. OBJECT OF THE INVENTION It is noted that there is a need to provide a hauling device ready for use and easily transportable. This need is solved by means of a hauling device which comprises: a first fixing member intended to be fixed at a fixed point and comprising a first set of at least two pulleys, a second fixing member intended to be attached to a person to be rescued and having a second set of at least two pulleys, A rope attached to one of the two fasteners and arranged to connect at least two pulleys of the first fastener with at least two pulleys of the second fixing member so that the first fixing member approaches the second fixing member during a draw of the rope, an envelope connecting the first fastener to the second fixing member and surrounding the path of the rope between the two fixing members, one end of the rope coming out of the envelope to allow drawing of said end. 30 Brief description of the drawings Other advantages and features will become more clearly apparent from the following description of particular embodiments of the invention given by way of nonlimiting example and represented in the accompanying drawing, in which: FIG. 1 is a diagrammatic representation of a hauling device without 2a and 2B show diagrammatically a hauling device with its envelope in an elongated configuration and in a shortened configuration, FIGS. 3a, 3b, 4a and 4b schematically represent perspective views and views. exploded fasteners.
    [0003] DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION The hauling device comprises first and second fixing members 1a and 1b advantageously and / or advantageously formed by first and second pulleys. The first pulley is intended to mate mechanically to a fixed point. The second pulley lb is intended to mate mechanically to the person to be rescued.
    [0004] In a first situation, the first pulley is connected directly or indirectly to a relay or fixed point. The second pulley lb is connected to the rope that holds the person to rescue. In this configuration, the person to be rescued is lifted by pulling on the rope that holds him. This situation can happen when the person has fallen into a crevasse or when a second party is blocked.
    [0005] In a second situation, the first pulley is connected directly or indirectly to a relay via the rope that initially retains the person to rescue. The second pulley 1b is connected directly or indirectly to the person to be rescued. The person to be rescued is then supported by the hauling device which organizes the movement of the person to rescue for example on another rope. The two situations indicated above are given by way of example.
    [0006] Other situations are possible. The first pulley 1a comprises a first sheave 2a and preferably a first set of at least two sheaves 2a mounted side by side. The second pulley 1b has a second sheave 2b and preferably a second set of at least two sheaves 2b also mounted side-by-side. By mounted side by side, it is meant that the two sheaves are shifted laterally along the axis of rotation of the two sheaves. Advantageously, the rotational axes of sheaves 2a and 2b are coaxial. It is also conceivable to provide that the two sheaves 2a and / or 2b do not share the same axis and that they are offset perpendicular to the axis of rotation, but this configuration is less advantageous because it is less compact. By réa, we mean a grooved wheel, that is to say the moving part in which a rope is wound. The two pulleys la and lb are connected via a rope 3 or wire connector. The rope 3 is advantageously fixed to one of the pulley 1 to gain compactness so that the fixed connection to the fastener defines an end of the rope. Advantageously, the rope is tied at an orifice of one of the pulleys. Preferably, the orifice is made in a fixed flange of the pulley.30 The rope 3 travels through the sets of sheaves 2. The path of the rope 3 is such that it moves alternately one of the organs of attachment to the other fastener. In the embodiment illustrated in FIG. 1, the rope 3 is fixed to the first pulley 1a, then it winds partially around one of the sheaves 2b of the second pulley 1b and then redirects to the first pulley the. The rope 3 wraps around one of the sheaves 2a to move back to the second pulley lb. The rope 3 then leaves the second pulley for the first pulley 1 a. The rope 3 is then made available to allow manipulation by the user.
    [0007] The path of the rope 3 between the various sheaves is any as long as the pulling of the rope 3 results in a bringing together of the two pulleys la and lb. In this way, pulling the rope 3 brings the two pulleys la and lb together.
    [0008] Advantageously, the first and / or second pulley 1a and 1b comprise a self-locking member 4. The self-locking member 4 is configured to allow the bringing together of the two pulleys 1a and 1b and prohibit their removal. In this way, the draw of the rope 3 will cause the movement of the second pulley relative to the first pulley, which allows for example to lift the person to rescue. If the rope 3 is released voluntarily or involuntarily, the distance between the two pulleys la and lb is maintained as the self-locking member 4 is not disabled.
    [0009] In a particularly advantageous embodiment illustrated in FIGS. 1, 3 and 4, the first and second pulleys 1a and 1b are formed by double pulleys, that is to say with two integral sheaves, which makes it possible to have an efficient gearing without having a large volume.
    [0010] In a preferred configuration, the first and second pulleys la and lb comprise a through hole 5a / 5b which allows the passage of a carabiner (not shown). This configuration is particularly advantageous because it allows to quickly change the carabiner for another carabiner having a size and / or shape more adapted to the specific needs of the user. Alternatively, it is also possible to provide a fastening system mounted on the pulleys, but this configuration is less convenient. The carabiner can be replaced by any other removable connector, for example, a link, a shackle and possibly a strap.
    [0011] As the sheaves are integral with the pulley, a single attachment point is used for each of the pulleys 1a / 1b which allows for maximum performance because the two sets of sheaves are facing each other. The path of the rope 3 is then natural and without friction point.
    [0012] The hauling device also comprises an envelope 6. The envelope 6 is configured to attach to the first and second pulleys 1a and 1b. Advantageously, the envelope 6 is configured to be removably mounted which allows access to the interior of the hauling device. The envelope 6 is configured to cover the path of the rope 3 between the sheaves 2a / 2b and allow the exit of the end used to draw the rope 3. The hauling device intended to serve that in exceptional cases, the device is stored in a bag with the rest of the equipment. It has been discovered that the envelope 6 connecting the two pulleys 1a / 1b and defining a sheath around the multiple paths of the rope 3 prevents the formation of knots. Indeed, when the device is not used and in the absence of envelope 6, it has been observed that nodes can appear or that the different entanglement string paths.
    [0013] Under these conditions, the hauling device is unusable, it is necessary to disassemble the various elements which is particularly anxiety.
    [0014] The use of the envelope 6 makes it possible to constrain the arrangement of the hauling device and more particularly the different passages of the rope 3 between the sheaves 2a and 2b.
    [0015] As illustrated in FIGS. 2a and 2b, the envelope 6 is flexible in a first direction so as to allow a modulation of the length between an elongated position where the two fixing devices 1a and 1b are remote and a shortened position where the two fixation 1a and 1b are brought together (after drawing rope 3). This flexibility can result in compressibility of the envelope during the pulling of the rope. The envelope 6 is advantageously flexible in another direction to allow easy storage of the device. This freedom of movement in several directions does not hinder the operation of the device while ensuring a drastic reduction in the risk of knots or entanglement of the rope. In operation, the device is stretched and therefore linear.
    [0016] This configuration makes it possible for example to fold the hauling device to save space. This also allows a twisting of the central part of the device during storage. The envelope 6 may be formed by a continuous non-perforated material, a perforated material or an assembly of these two materials. The casing 6 is advantageously made of a material of textile type which allows good malleability with negligible overweight. The envelope 6 is formed at least partially in a compressible material so as not to create a force that opposes the bringing together of the two fasteners during the pulling of the rope 3. The continuous material may be a fabric which allows protect the inside of the device and reduce the introduction of dirt. The perforated material is for example a net which allows to quickly detect a wear of the rope inside the hauling device or another element for safety. Advantageously, the net is made of a polymer material which facilitates drying, for example in a lycra-type material.
    [0017] In a particularly advantageous configuration, the portion of the envelope 6 in contact with the first and / or second pulleys 1a / 1b is made of a more rigid material than that used to surround the multiple rope passages 6. These portions in contact with the two pulleys 1 a / 1 b advantageously form the ends of the envelope 6. The formation of a more rigid envelope 6 at the ends allows a better operation of the device because it reduces the risk of deformation of the envelope nearby sheaves which avoids a nuisance blocking. Advantageously, the material forming the ends of the envelope is a more rigid material, for example leather or a soft plastic material injected, a coated fabric advantageously of the PVC or polyurethane type. The increased rigidity can be achieved by providing a thicker material. The increase in rigidity at the ends reduces the risk of the envelope deforming around the sheaves and getting caught between a sheave and the rope.
    [0018] Preferably, the portions in contact with the fasteners la / lb are fixed to said fasteners which avoids unwanted displacement of the envelope 6 in use and limits the risk of jamming in the sheaves. In a particular configuration, the portions in contact with the pulleys 1a / 1b comprise an orifice which cooperates with the orifice 5 present in the pulleys 1a and 1b. In this way, the carabiner ensures the attachment of the envelope 6 with the pulley 1 a / 1 b. It is then possible to easily remove the pulley 1 a / 1 b by removing the carabiners. Overweight is limited because there is no superfluous room.
    [0019] In the embodiment illustrated in FIGS. 3a and 3b, the first pulley la is an unlockable blocking pulley associated with a single pulley. These two elements are mechanically associated to form a first pulley monobloc.
    [0020] The integrated blocking pulley has a small footprint and ease of use which are particularly interesting. As illustrated in FIG. 3b, the first pulley la has a first fixed flange 7 serving to support a first axis 8 of a rotating roller 9, and a second pivot pin 10 of a locking pin 11. The two axes 8, 10 are fixed, and advantageously extend parallel to each other in a direction perpendicular to the first flange 7. The cylindrical roller 9 is mounted for free rotation about the first axis 8, and is provided with its periphery of an annular groove for guiding the rope 3 in the sheave. The pivoting trigger 11 is provided with a braking surface intended to press the rope 3 against the roller 9 to form a blocker integrated in the space between the two axes 8, 10. The braking surface comprises a plurality of inclined pins intended to to reinforce the locking effect of the rope when the blocker is active. A spring 12 urges the trigger 11 towards the roller 9.
    [0021] A second movable flange 13 is tiltably mounted on the end of the first axis 8 between a closed position and an open position. The open position of the second flange 13 allows the introduction of the rope 3, after having moved the trigger 11 to the inactive position, moving it away from the roller 9.
    [0022] In the closed position of the second flange 13, the rope 3 is wound in a loop on the roller 9, and is trapped in the transverse gap formed between the flanges 7, 13 advantageously parallel. The first flange 7 has a first orifice 14 located near the second axis 10, and above the rotary roller 9. The second flange 13 is provided with a second orifice 16, which comes into alignment with the first orifice 14 when the two flanges 7, 13 are positioned in the closed position. The two orifices partially define the orifice 5a. It is then possible to introduce a removable connector to hold the flanges 7, 13 in this position by preventing inadvertent tilting. Above the first orifice 14, there is a stud 17 fixed to the first flange 7, occupying the transverse gap between the flanges 7, 13. The stud 17 is equipped with a latch 18 capable of pivoting about an axis 19 between a locked position and an unlocked position. The pivot axis 19 of the latch 18 is advantageously parallel to the second axis 10 of the trigger 11. A third movable flange 20 is mounted to tilt, preferably on the end of the first axis 8 between a closed position and an open position. A second cylindrical roller 21 is mounted preferably free to rotate about the first axis 8, and is provided at its periphery with an annular groove for guiding the rope. The second roller 21 separates the flanges 7 and 19.30. Above the first orifice 14, there is a stud 22 fixed to the first flange 7, occupying the transverse gap between the flanges 7 and 19. In this configuration, each face of the first flange 7 is equipped with a stud.
    [0023] The open position of the third flange 20 allows the establishment of the rope. In the closed position of the third flange 20, the cord is wound in a loop on the roller 21, and is trapped in the transverse gap formed between the flanges 7, 20. The third flange is advantageously deformed in the cooperating zone before the stud 22 so as to limit the protuberance formed by the stud and reduce the bulk of the first fastener la. The third flange 19 has a first orifice 23 located above the rotary roller 21. The first orifice 23 of the third flange 20 comes into alignment with the first orifice 14 when the two flanges 7 and 20 are in the closed position. The orifices 14, 15 and 23 define the orifice 5a. It is then possible to introduce a removable connector to hold the flanges 7, 13 and 20 in this position by preventing inadvertent tilting.
    [0024] In the embodiment illustrated in Figures 4a and 4b, the second fixing member 1b is formed by a double pulley without self-locking member. The two sheaves are mechanically associated to form a monoblock pulley lb.
    [0025] As illustrated in FIG. 4b, the second fixing member 1b has a first fixed flange 24 serving to support a first axis 25 of a rotary roller 26.
    [0026] The axis 25 is fixed, and extends in a direction perpendicular to the first flange 24. The cylindrical roller 26 is mounted to rotate freely about the first axis 25, and is provided at its periphery with an annular groove for the guidance of the rope.
    [0027] A second movable flange 27 is tiltably mounted on the end of the first axis 25 between a closed position and an open position. The open position of the second flange 27 allows the establishment of the rope. In the closed position of the second flange 27, the rope 3 is wound on the roller 26, and is trapped in the transverse gap formed between the flanges 24 and 27. The first flange 24 has a first orifice 28 situated above the roller 26 rotating. The second flange 27 is provided with a second orifice 29, which comes into alignment with the first orifice 28 when the two flanges 24 and 27 are positioned in the closed position. The two orifices partially define the orifice 5b. It is then possible to introduce a removable connector to maintain the flanges 24 and 27 in this position by preventing inadvertent tilting.
    [0028] A third movable flange 30 is tiltably mounted, preferably on the end of the first axis 25 between a closed position and an open position. A second cylindrical roller 31 is mounted preferably free to rotate about the first axis 25, and is provided at its periphery with an annular groove for guiding the rope. The second roller 31 separates the flanges 24 and 30. The second flange 30 is provided with an orifice 32, which comes into alignment with the first orifice 28 when the two flanges 24 and 30 are positioned in the closed position. The three orifices 28, 29 and 32 define the orifice 5b. It is then possible to introduce a removable connector to hold the flanges 24, 27 and 30 in this position by preventing inadvertent tilting.
    [0029] Above the first orifice 28, there is a stud 33 fixed to the first flange 24, occupying the transverse gap between the flanges 24 and 27. Advantageously, the stud 33 is configured to occupy the transverse gap between the flanges 24 and 30. In this configuration, each face of the first flange 24 is equipped with a stud.
    [0030] The second and third flanges 27 and 30 are advantageously deformed in the zone cooperating before the stud 33 so as to limit the transverse protrusion formed by the stud 33 and reduce the bulk of the second fastener lb.15.
