Abstract

The reel (1) has a drum (4) to accommodate several rings (5) of a rope (2). The drum is supported by a belt harness (6) and a rucksack (8), so that a human carrier (3) of the reel supports the drum in a hands free manner, where the drum is accessible and/or operable by the carrier for wrapping and storing the rope in the drum. The drum extends between an internal end (4I) located toward the belt harness and an external end (4E) located outwardly with respect to the belt harness, where the drum is rotatable about a winding axis (X-X') of the rings of the rope. An independent claim is also included for a method for securing a person with a rope to prevent a slip or an accidental fall.

Description

PORTABLE ROPE REEL FOR ADJUSTABLE INSURANCE

The present invention relates to the general field of devices for storing and transporting ropes or cables in different types of activities, and more particularly in the field of belaying when it is necessary to guarantee the safety of a machine. person practicing mountaineering or speleology, participating in a rescue operation in the mountains or intervening on a site or facility located at a significant height of the ground.

The present invention relates in particular to a portable rope retractor for at least partial storage of a rope.

It also relates to the different uses of such a retractor as an accessory for different activities, and in particular a belaying method allowing at least a first person to be assured with respect to a belay element, which can be a second person or an object, to prevent a slip or accidental fall or to limit the consequences of such a slip or fall.

It has long been known to use ropes to ensure a person working at height or practicing an activity that exposes him to a risk of slipping or falling that can lead to injury or even death.

For this purpose, it is known to connect the insured person to a belay element that can be either another person or an object forming a fixed anchoring element relative to the ground on which the person moves, such as a rock, a piton or a ring sealed in the ground, a metal gallows, the guardrail of a basket, etc.

Thus, in the event of a fall or slipping, the insured person is retained by the connecting strand formed by the portion of rope, of predetermined length, which extends between said anchoring element and an attachment point connected to the person insured by a safety organ such as a harness, belt or shoulder belt. If so, the magnitude, and therefore the gravity of slipping or falling, are therefore limited by the length, and in some cases the elasticity, of said connecting strand.

Of course, it is appropriate to adjust case by case the length of said connecting strand depending in particular on the nature of the terrain on which the insured person moves, this length may vary during the activity performed. The available cord having necessarily a predetermined total length, chosen greater than the maximum length of the connecting strand which is expected to be necessary, this involves managing a supply of rope to provide if necessary to lengthen or shorten said connecting strand.

For this purpose, it is known to make "bust rings" by wrapping around the bust of the insured person the surplus of rope which extends opposite the connecting strand, beyond the nceud of attachment which maintains said rope to the harness.

Although such a technique actually makes it relatively easy to carry the surplus rope, it nevertheless presents certain disadvantages.

Firstly, it requires the insured person special care and attention when making the bust rings, which must be loose enough not to constrain the bust but tightened enough to avoid any risk of snagging with an arm or an obstacle surrounding the wearer, and which must also not interfere with the belay itself, the effort of belaying to be exerted on the shoulder belt provided for this purpose, and especially not on the body of the carrier by the intermediate said bust rings.

In addition, once the rings in place on the bust, they prevent the insured person from removing clothes or on the contrary to put on new clothes, and may to some extent impede access to the various accessories possibly worn by the person , such as ice axes, carabiners, gourd, cards, or even prevent the use, installation and recovery of the backpack, etc., or, in general, hinder certain movements, including certain respiratory movements of the person assured. In addition, such bust rings can not be mobilized quickly, which can be problematic in the case of an emergency.

In particular, the unwinding of such rings must be operated relatively slowly, one ring at a time, to avoid any risk of entanglement, and in movements that may be difficult to perform.

Secondly, both the constitution of bust rings and the unfolding thereof can be relatively inconvenient, and in particular require the insured person, or the insurer, to place themselves in an uncomfortable position or presenting a risk of imbalance, or that it proceeds with unnatural or large-scale movements, which can be tricky or even perilous on rough terrain or in an emergency.

Finally, in addition to the difficulty that the insured person may experience during the execution of movements, it can be very unpleasant for her to have to wind directly in contact with her bust a cold rope, wet, snowy, or soiled by dust or mud.

The objects assigned to the invention therefore seek to overcome the aforementioned drawbacks, and to propose a new method and a new rope storage means which are particularly practical and safe for the user of said rope.

Another object assigned to the invention is to propose a new rope storage means which has good ergonomics, and whose use is particularly comfortable, simple and intuitive.

Another object assigned to the invention is to propose a new means and a new rope storage method which are particularly reliable.

Another object assigned to the invention is to propose a new means and a new method of storing rope which allow a winding, or on the contrary a particularly rapid unwinding and mobilization of the rope rings. B 11642 / FR Another object assigned to the invention is to propose a new rope storage means which is particularly robust, lightweight, compact, and inexpensive to manufacture.

Another object is to provide a novel rope storage means which is versatile and can be adapted to many use configurations.

Another object assigned to the invention is to propose a new method of belaying which is particularly safe, convenient, and easy to implement, including by a person with little experience.

The objects assigned to the invention are attained by means of a portable rope winder intended for the at least partial storage of a rope, said reel being characterized in that it comprises a drum capable of accommodating several rings of said rope, said drum being on the one hand supported by harnessing means, of the belt, harness or backpack type, allowing the wearer of the furler to carry said drum while keeping his hands free, and secondly arranged so as to remain, when the wearer carries said retractor, accessible and / or maneuverable by the wearer himself in such a way that said carrier can at will to wind it and, conversely, unroll the rope.

The objects assigned to the invention are also achieved by means of a belaying method enabling at least a first person to ascertain with respect to a belay element, which may be a second person or a object, in order to prevent an accidental slip or fall or to limit the consequences of such a slip or fall, said method comprising at least one step (a) of roping during which said first person is connected to the anchoring element by means of a rope forming between them a connecting strand, said method being characterized in that it comprises a storage step (b) during which the first person and / or where appropriate, the second person wraps the soft strand of the rope, which forms the surplus of rope extending or intended to extend beyond the connecting strand, on a winder which it carries on it.

The present invention relates to a rope winder 1 for the at least partial storage of a rope 2.

Within the meaning of the invention, the term "rope" 2 can denote any type of flexible rope, including in particular one or more strands, said rope is made of a textile material, natural (for example hemp) or synthetic (for example nylon), or even in a metallic or even composite material.

The rope 2 may thus constitute, where appropriate, an electric cable, a wire rope or, particularly preferably, a safety lanyard for work in the basket, on a scaffold or on a roof, or a climbing rope. resistant enough to ensure a human person 3 (also referred to as "carrier 3" in the following) in order to prevent accidental slipping or falling, or to limit the consequences of such slipping or such a fall.

Of course, the material (s) constitutive (s) of the rope 2, and the diameter of its cross section, will be determined accordingly, so as to be able to support the weight of the body of said carrier 3, and where appropriate support or even damp the inertial shock caused by the fall of said carrier a height at least equal to the rest length of said rope 2. B11642 / FR As a preferred example, the rope 2 may be formed by a rope of climbing made of polyester or polyamide and whose section diameter will be substantially between 9 mm and 11 mm for mountaineering ropes, or between 8 mm and 11 mm for rope works of height or speleology.

According to the invention, the winder 1 comprises a drum 4 which is able to accommodate several rings 5 of said rope 2, and which has a winding axis () OC) substantially corresponding to its generator and around which said rings roll up forming successive loops.

Thus, one can advantageously store all or part of the rope 2 by winding the latter on said drum 4 in a plurality of substantially concentric rings 5, which can advantageously be juxtaposed in several substantially parallel rows along the winding axis () OC), and / or superimposed in several concentric layers of increasing diameter about said winding axis () OC), in a well-ordered manner and without risk of entanglement, loosening or excessive tightening, as this is particularly illustrated in Figures 12 and 18.

According to an important characteristic of the invention, said reel 1 is portable, the drum 4 being for this purpose supported by means of harnessing 6, such as belt, harness, shoulder strap, shoulder belt, or even backpack 8, which allow the carrier 3 of said reel 1 to carry said drum 4 keeping his hands free.

Preferably, the harnessing means 6 form a backpack 8, as illustrated in particular in FIGS. 17 and 18, said backpack 8 comprising at least one bag 8A, here dorsal, intended for the transport of various loads, such as clothing, equipment, foodstuffs, etc., the drum 4 being attached to said pocket 8A, outside the latter, and particularly preferably on the side wall of said backpack and said pocket.

According to a preferred embodiment, the harnessing means 6, and more particularly the backpack 8, will comprise a plurality of drums 4 in even number, and more particularly a pair of drums 4, distributed in a balanced manner on each side of the bearer, and more particularly because of a first drum on

B 11642 / FR the left side wall of the backpack 8 and a second drum on the right side wall of the same backpack, as shown in Figure 18.

Advantageously, the retractor 1 is thus embarked on the carrier, that is to say "man-back", said carrier 3 using his muscular force to lift and move the drum 4 and, where appropriate, the stock 2 of the rope that it contains, and this without being hampered by said drum 4, nor a fortiori be engaged in the rope rings 5, since the latter are formed on said drum 4 rather than its bust, the body of the remaining carrier thus released because it stands out loops formed by said rings.

In addition, said drum 4 is arranged so as to remain, when the wearer 3 carries the reel 1, accessible and / or maneuverable by said carrier 3 itself, so that said carrier 3 can, at will, there roll up and, conversely, unwind the rope 2.

Thus, the drum 4 is advantageously arranged in such a way that the carrier 3 can operate at any time a mobilization of the rings 5, that is to say a release of the rope stored on the drum 4, and / or on the contrary, storage of the surplus rope by winding new rings 5 on said drum 4, and in a direct manner, without the need to discard the winder 1, for example by depositing his backpack.

More particularly, the carrier 3 can thus modify at will, and particularly quickly and conveniently, the length of the connecting strand 2A which connects it to the belay element 10, which may be a second person 3 'or any object forming a secure anchorage, such as a rock, a tree, a beam, a mooring ring, a bolt, a guardrail, etc.

According to whether it will shorten or otherwise lengthen said connecting strand 2A, that is to say, as it will decrease or increase the maximum distance that can separate it from the belay element 10, the carrier 3 can mobilize the rings 5 stored to "give slack" by giving an extra length to the connecting strand 2A, or on the contrary to form more rings 5 in order to absorb and store the surplus of soft strand 2B gained on the connecting strand 2A .

B11642 / FR As such, it will be noted that, preferably, the winder 1, and more particularly the drum 4, is used exclusively for passive storage of a portion of the rope 2 which is not solicited by the belay.

In other words, the drum 4 is preferably not subjected to the potential shocks and tensile forces, potentially violent, which are transmitted from the first insured person 3 to the belay element 10, and more particularly to the second insurer 3 ', via the connecting strand 2A, when the latter is stretched for example due to a slip or a fall of the insured carrier 3.

For this purpose, as shown in particular in FIGS. 17 and 18, said connecting strand 2A may advantageously be delimited, at its ends, by stop nodes 11, 12, for example of the eight-knot or knot node type. of a chair, which firmly attach the connecting strand 2A to a specific retaining structure 13, of the harness or harness type which holds the wearer 3 and supports the possible mechanical load related to the effects of the belay, and which may advantageously to be distinct from the harnessing means 6.

The so-called "soft" strand (s) 2B (by analogy with the strands of a transmission belt), which may also be designated as "free strands" in the following, extend for their part beyond said arresting knots. 11, 12, opposite the active connecting strand 2A, said soft strands 2B corresponding to portions of the rope 2 which remain substantially loose because protected by said stopping nodes 11, 12 of any tension and any transmission belay force likely to be exerted by and on the connecting strand 2A when it stretches. Thus, no pulling force is likely to be exerted on the drum 4, the latter being subjected at most to the weight of the soft-strand rings 2B wound therein.

In this respect, it is remarkable that, as shown in FIG. 18, the soft strand (s) 2B may be constituted differently, according to the belay configuration that the insured person 3, 3 'wishes to implement. and according to the order of the acts of belay that she performs for this purpose. B 11642 / FR Thus, said person 3 may, for example, decide, as illustrated on the right-hand part of FIG. 18, to attach first of all to the rope 2 by the first end 2C of the latter, in fixing said end 2C to the shoulder 13 by a first stop node 11 'able to firmly hold said harness to said rope.

It can then constitute the soft strand 2B in the form of a "strand of recovery", by shortening the connecting strand 2A to reduce the length available between it and the belaying element 10, and by "progressively" raising the along the rope towards the second 2D end thereof, and by coiling in the form of rings 5 the excess length regained on the connecting strand 2A. Once the desired length of the remaining connecting strand 2A has been reached, it produces a second stopping node 11 on the same shoulder 13 so that the soft strand 2B, recovered on the connecting strand 2A and stored on the drum, is located captive, although substantially free of constraints, between the two stopping nodes 11, 11 'ensuring the same person.

Alternatively, as illustrated on the left-hand part of FIG. 18, the person 3 'can first of all make a stop node 12 on his harness 13 in an intermediate portion of the rope 2, leaving free the opposite end to the connecting strand 2A, and then recalling the free strand located between this intermediate attachment point and the free 2D end of the rope, opposite the other person 3, until the soft strand 2B, forming the free end section of the rope, is found entirely caught on the drum 4.

Preferably, the drum 4 extends, according to its winding axis () (X '), between a first inner end 41 located towards the harnessing means 6 and a second free external end 4E opposite, which projects towards the outside said harnessing means 6.

Advantageously, the drum 4 therefore preferably extends in free projection, preferably in a direction substantially normal to the wall of the harnessing means 6 which holds it, so as to be substantially cantilevered, a little to the way of a bollard.

Thus, the drum 4 remains easily accessible to the hand of the carrier 3 by its second outer end 4E released, as shown in Figure 17. B 11642 / FR 2978132 It Preferably, as shown in the figures , the drum 4 extends, along the winding axis (XX '), between a first cheek 14 and a second cheek 15 which form respectively, at each of the first and second ends 41, 4E of the drum 4, a first and a second retaining rim projecting radially, that is to say substantially normal transverse to the winding axis () X '), with respect to said drum 4.

Preferably, the free radially outer edge of the flanges 14, 15, which marks the outer cutout of the winder 1, follows a path substantially parallel to the winding path 18 of the cord, as defined by the surface of the drum 4 on which 10 the rope rings 5 are applied, and if necessary tighten.

Advantageously, the drum 4 can thus be substantially contained between two flanges 14, 15 capable of axially retaining the rope rings 5 on said drum 4.

Advantageously, the cheeks 14, 15 axially retain the rings and protect the latter by limiting their exposure to the wearer himself or to his environment. The rope supply 2 on board the carrier can thus remain wound in a stable and orderly manner, in a dedicated and preserved volume, without the risk of hanging freely, becoming entangled or catching any obstacle.

Said cheeks 14, 15 may advantageously be formed by plates, preferably substantially perforated at their center so as to form the extension 20 of a hollow drum 4, said plates being either substantially planar (FIGS. 1 to 6), or slightly concavely curved towards the drum 4 (Figures 7 and 8), for example to improve their rigidity or facilitate their production by molding.

Said cheeks 14, 15 may also comprise stiffening structures, such as corrugations 16, and / or reinforcement structures, such as ribs 17, which reinforce and stiffen their connection with the drum 4, at the hub of said cheeks 14, 15, as particularly illustrated in FIGS. 9, 13 and 14. B11642 / FR As such, it is remarkable that the first and / or second cheek 14, 15 are preferably formed in one piece , and preferably by molding, with respectively a first section 20 and a second section 21 of the drum 4.

Said drum 4 can then advantageously be reconstituted by assembling said first and second sections 20, 21, as shown in particular in FIGS. 5, 13, 14 or 16A, said assembly being carried out either directly (FIG. by simple abutment, or again, if necessary, on either side of one or more intermediate sections 22 as shown in Figures 13, 14 and 16A.

Preferably, the drum 4, and in particular one or other of its sections 20, 21, 22, as well as the first and / or second cheek 14, 15, will be made of a rigid or semi-rigid material for example in a light metal alloy, of aluminum alloy type, in a plastic material, of the ABS type, or even a composite material, for example based on carbon fibers.

As such, it is however remarkable that due to the relatively moderate constraints to which the drum is likely to be subjected, it is possible to confer a relatively light structure, including openwork.

It is also conceivable to use for its construction, and in particular for the production of the flanges 14, 15, a weakly rigid or even substantially elastic material, conferring on the drum 4, and more generally on the winder 1 as a whole, a character substantially atraumatic that avoids hurting the wearer if the hand of said wearer collides with the occasion of winding or unwinding of the rope, or in case of fall of said carrier 3 on the drum 4.

Furthermore, although it is not excluded that the drum 4, and more particularly its hub, can be full, the latter will preferably be hollow so as to lighten the winder and facilitate its manufacture.

In addition, said drum 4 may be delimited substantially all around the winding axis (XX ') in a closed contour, so as to offer a bearing surface

B 11642 / FR substantially full and continuous over most or all of the winding path 18, as shown in Figures 11 to 14, is further subdivided into a plurality of spacers 25 separated and distant from each other. others, and more particularly distributed punctually around the winding axis (XX '), along the winding path 18 of the drum 4.

Said spacers 25 may each form open curved deflection surfaces (FIGS. 2 and 4), or closed, substantially circular and / or polygonal (and in particular rectangle) closed base cylinders, and axes substantially parallel to the axis of FIG. winding, as shown in Figure 6 (with, in this case, four cylindrical spacers arranged at the "corners" of the winding path) and 16 (with, in this case a front spacer substantially rectangular base and a substantially circular base back spacer).

Depending on the case, the rings 5 can therefore be supported substantially over the entire perimeter of the drum 4, or else instead stand punctually on spacers 25 which mark and materialize the winding path 18 between which said rope rings are substantially tensioned, or at least suspended, by substantially drawing the segments of a broken line.

Advantageously, a perforated drum gains in lightness, but also allows, according to a preferred embodiment, to use the winder 1 to hang various tools or accessories useful to the wearer, other than the rope itself, and for example to support a ski on the backpack 8 when said ski is not shod.

More particularly, according to a feature which may constitute an invention in its own right, the extrados 30 of the drum 4 may be perforated so as to form the opening of a bucket 42 designed to receive and retain the heels of a gliding board , such as a ski.

As such, the underside 31 of said drum 4 may be substantially full, so as to form the bottom of said bucket 42 and retain the heel of the ski by preventing the latter from crossing said drum 4 from one side. B 11642 / FR According to another embodiment, corresponding for example to that of Figures 1 to 5, the intrados 31 may also be perforated so as to leave a free passage to the heel of the gliding board, and more particularly the ski , through the drum.

The second outer cheek 15 may then comprise a retaining notch 32, forming a cutout in its upper part, for example substantially rectangular or trapezoidal, said notch being designed to form a stop against the attachment of the ski, so as to block the descent of the latter when it is introduced through the drum 4 from above the reel.

Where appropriate, such a bucket 42 may advantageously be associated with a second support forming a wedge for the upper part of the ski, and more particularly for its spatula, said second support being disposed on the same side wall of the bag 8 as the drum 4 at a vertical distance vertically above the latter, and said support being able, if necessary, to have a receiving receptacle stepped in convergent steps of decreasing widths, so as to be able to accommodate alternately different gliding boards of different sizes (ski bottom, ski trail, surf ...), the sole of the concerned board lying flat on one or the other of said steps.

Thus, by disposing on each side of the backpack of a godetlsupport pair stepped, can be transported easily and particularly stably a pair of skis, one ski against the bag, in a vertical position, on each side wall, on either side of the main pocket of said backpack.

In a particularly preferred manner, the drum 4 is fixed to rotate about the winding axis OO (»of the rope rings 5.

More generally, said drum 4 will preferably be substantially invariant in position, and more particularly in angular position, with respect to the harnessing means 6, and therefore with respect to the carrier 3.

Advantageously, it may for this purpose be integral with, and in particular formed in one piece with, the first inner cheek 14 which forms the sole by which it rests on

B 91642 / FR the harness means 6, and more particularly by which it is attached to the side wall of the backpack 8.

Advantageously, such a fixed drum mechanism simplifies and alleviates the structure of the winder, and also gives a particularly reliable and stable storage character, substantially limiting any risk of accidental unwinding of the rope rings 5, as well as the risks of entanglement, since it is almost impossible to unroll brutally and / or accidentally a large number of turns of rope likely to put in a ball.

Moreover, the drum 4 is, in a particularly preferred manner, fixed on the harnessing means 6 so that, when the reel 1 is worn, the winding axis (XX "of the drum 4 extends laterally through to the carrier, in a direction transverse to the latter, and more particularly to the left from its left flank or to the right from its right side, as shown in Figures 17 and 18.

According to a characteristic which can constitute an invention in its entirety, in particular independently of the use of harnessing means 6, the drum 4 can have, transversely to its winding axis () OC ", an asymmetrical shape which goes into slimming between a wide leading edge 33 and a trailing edge 34 narrower than the leading edge.

Advantageously, such an asymmetric shape, substantially crushed, can firstly produce a better retaining effect against the sliding of the rings along the winding path 18, or against the spontaneous development of said rings 5 which would tend to occur around a drum 4 which would have a circular shape.

In addition, such a shape can be particularly adapted to the natural movements of the arm during winding, and thus make the winder 1 particularly ergonomic. B 11642 / FR As such, as shown in particular in FIG. 17, the leading edge 33 is preferably oriented towards the front of the carrier 3, the trailing edge 34 facing towards the rear of the carrier, advantageously within arm's reach, the upper surface 30 being directed towards the top and the lower surface 31 facing downwards from the ground.

The extrados 30 of the drum can then preferably follow globally, from the leading edge 33 to the trailing edge 34, a downward slope, oriented from top to bottom.

Preferably, the drum is moreover arranged in such a way that its length (considered from the leading edge to the trailing edge) is greater than its height, the drum thus extending in length substantially in the anteroposterior direction of the carrier 3, here substantially horizontal.

Advantageously, when the drum 4 is arranged projecting against the side of the carrier 3 or in the vicinity of the side of the carrier, as is the case when it is attached to the side wall of the backpack, the winding axis (XX ') pointing in a mediolateral direction, such an arrangement allows the corresponding arm of the wearer 3, located on the same side as the drum, to bring and wind the rope around said drum 4 in a rotary motion of trajectory and of very natural amplitude, the height to be crossed at the trailing edge 34, further from the shoulder of the wearer, being less than that of the leading edge 33 closer to said shoulder.

In a particularly preferred manner, the section of the drum 4 normal to the winding axis (XX ') can follow a profile whose variations are particularly soft and progressive, and in particular a profile which is close to a quarter of an ellipse.

Of course, other profiles are possible for the winding path 18, including ovoid profiles or polygonal profiles and in particular trapezoidal, the edges of which must however be rounded so as to avoid the shearing of the rope rings.

Preferably, the extrados 30 may form (FIG. 15), or at the very least initiate (FIGS. 4 or 16B), a domed facing upwards, whereas the intrados 31 may

B11642 / FR follow a substantially flat surface, advantageously parallel to the horizontal when the wearer is standing, as shown in FIG. 17.

The leading edge 33 may in turn be formed by a surface portion, optionally substantially planar or convex convex, which may also be substantially vertical Figure 15, 16B) or slightly bent forwardly (Figure 4).

Furthermore, according to a feature which can constitute an entire invention, regardless of the shape of the drum or the presence of the harnessing means 6, the drum 4 can be at least partially retractable so as to allow the adjustment of its depth P, and more particularly the distance that axially separates its inner cheek 14 from its outer cheek 15.

More particularly, the drum 4 can thus pass alternately from a folded configuration, as illustrated in FIGS. 7, 11, and 14, in which it has a first minimum depth P1, in an expanded configuration, illustrated in FIGS. , 12 and 13, wherein it has a second depth P2, greater than said first minimum depth P1.

If necessary, the drum 4 may be capable of occupying any configuration of intermediate depth between these two extremes.

Advantageously, such an arrangement makes it possible to fold or on the contrary to deploy the reel 1, and thus to modify or adjust the spacing distance between the cheeks 14, 15.

It is thus possible not only to adapt the effective reception capacity to the storage need, taking into account the length of the soft strand 2B and its section diameter, but also, if necessary, fold the drum 4 towards, and possibly completely against, the inner cheek 14 and the wall of the backpack, so as to limit the size, and more particularly the transverse lateral overhang, of the reel when it is not used and remains empty rope. B11642 / FR For this purpose, the drum 4 may preferably comprise a plurality of sections 20, 21, 22 which fit into each other to form a telescopic structure along the winding axis OO (», as illustrated in particular in Figures 11 to 14, 16A and 16B.

More particularly, the drum 4 can be subdivided into three sections 20, 21, 22 of decreasing section width from one section to another. The sections may advantageously slide in smooth contact on each other to allow the drum 4 to retract or otherwise to deploy axially.

Said sections may in particular cooperate by latching, at least in their lower portion, by means of tongues 35 forming non-return lips allowing nesting but opposing the disengagement of the sections, as is illustrated in FIGS. 13, 15 and 16B.

As an indication, the retractor may preferably have a reception capacity of at least 7 m to 20 meters of a rope 2 whose section diameter is substantially between 8 mm and 11 millimeters.

More particularly, the depth P of the drum may be substantially between 20 mm and 40 mm, where appropriate in the folded configuration, or even reach at least 70 mm, 80 mm or even 100 mm, if necessary in deployed configuration. The drum may also have a length L (corresponding substantially to the half-major axis of the winding path when the latter is ellipsoidal) substantially between 200 mm and 300 millimeters, a height h33 leading edge 33 substantially between 80 mm and 150 millimeters and a height h34 trailing edge 34 substantially between 30 mm and 80 millimeters, the minimum perimeter of a turn of rope in contact with the drum 4, that is to say the length of the path of winding 18, which can be substantially between 40 cm and 75 cm.

Moreover, the useful height h15 of the retaining edge formed by the outer cheek 15 may be substantially between 20 mm and 50 millimeters, and thus allow a radial stack of 2 to 4 rings 5, and this substantially over the entire depth P of B 11642 / FR drum 4, the same drum can then accommodate up to 20, 30 or even 40 rings of rope,

On the other hand, according to a feature which may also constitute an invention in its own right, the drum 4 may be held by the harness means 6 by reversible fastening means (not shown) so as to be removable.

Advantageously, it will be possible in particular, depending on whether the activity envisaged requires the presence of a winder 1, add the drum 4 on the backpack 8 or on the contrary remove said drum 4 of said bag to get rid of this accessory when it is superfluous.

For this purpose, it will be possible to use as fastening means a strip or strap forming a loop which traps the inner cheek 14 against the side wall of the bag, this strap being advantageously able to be held by a Velcro system. If necessary, it would even be conceivable to provide all or part of the apparent surface of the first cheek 14 with a velvet intended to cooperate with hooks 15 arranged opposite one another, on the outer lateral wall of the backpack 8,

Furthermore, in order to improve the fixing and holding of the drum 4 on the bag, the inner cheek 14 may advantageously be provided with a tongue 40 forming a projection on its lower edge and intended to be driven into a slot or pocket corresponding in the harness means 6, and more particularly in the lower part of the side wall of the backpack 8.

Of course, the fixing of the drum 4 to the harnessing means 6 may be envisaged by any appropriate means and in particular by riveting, sewing, etc.

Furthermore, the invention also relates as such to each of the various embodiments of the drum 4 and its flanges 14, 15, obtained by separating or combining one or the other of the characteristics described above, as well as any use of such a drum 4 or a winder 1 according to the invention. B 11642 / FR In this respect, it will be noted in particular that the winder 1 can be advantageously adapted to allow the transport of electric cable by a carrier 3 using a power tool requiring a large supply of cable.

However, particularly preferably, the use of a retractor 1 according to the invention will be aimed at storing, on a person 3 assured, a surplus if not all of a belay rope 2, and more particularly the strand 2B that exceeds the connecting strand 2A by which said person 3 is attached to the belay element 10.

The implementation of a winder 1 according to the invention will therefore be described in more detail with such a belaying method.

As such, the invention relates of course to a belaying method allowing at least a first person 3 to make sure with respect to a belaying element 10, which can be a second person 3 'or an object, so prevent a slip or accidental fall or limit the consequences of such a slip or fall.

According to the invention, said method comprises at least one step (a) of roping during which said first person 3 is connected to the belaying element 10 by means of a rope 2, forming between them a strand of link 2A.

For this purpose, the first person 3, and, where appropriate, the second person 3 ', can advantageously attach said connecting strand 2A to their respective harness 13 by means of a stop node 11, 12 which blocks any movement said straps along the rope 2, as shown in Figure 18.

According to the invention, said method also comprises a storage step (b) during which the first person 3 and / or, if appropriate, the second person 3 ', winds the soft strand 2B of the rope 2, which forms the surplus rope extending (or intended to extend) beyond the connecting strand 2A, on a reel 1, and more particularly on a drum 4, which it carries on it, preferably on its bag. back 8A.

B11642 / FR To do this, she grasps the soft strand 2B, loose, and, to prevent it from dropping to the ground, recalls gradually to garnish the drum 4.

For this purpose, said person 3 advantageously slides said strand into the hollow of his hand while his forearm operates successive rotations plumb with the drum 4, in the co winding direction chosen, so as to gradually deposit the rope 2 in the groove defined by the cheeks 14, 15.

More particularly, it can thus wind several rings 5, turn after turn, progressing from the trailing edge 34 to the leading edge 33 by going up via the extrados 30, and then from the leading edge to the trailing edge when passing by the intrados 31, the vertical ascent is therefore progressive, the arm bringing the rope to the body, while the winding on the leading edge, close to the side of the wearer, is assisted by the gravity that acts on the rope.

Thus, the reel having a drum 4 which freely protrudes cantilever relative to the person 3 who carries the reel 1, the step (b) of storage comprises a sub-step (b1) of embodiment ring 5 during which said person 3 carries at least one ring 5, and preferably a plurality of rope rings 5, on the drum 4 by running his arm around said drum so as to distribute and wind the strand soft 2B in successive loops on the latter.

As mentioned above, and as illustrated in FIG. 18, the person 3, 3 'can proceed according to different orders according to the belay configuration which he wishes to implement.

According to a first configuration of belay, called "recovery configuration", it may for example decide, as illustrated with reference to the first person 3 on the right side of FIG. 18, to attach firstly to the rope 2 25 by the end 2C of the latter, fixing said end 2C to the shoulder 13 by a first stop node 11 ', then move closer to the belaying element 10 (the second person 3' on 18) to relax the connecting strand 2A and to wrap the excess, becoming the soft strand 2B, in the form of rings 5. Once the desired length is reached, the person 3 makes a second node of stopping 11 on the same B 11642 / FR shoulder 13 so that the soft strand 2B, stored on the drum, is captive, although loose, between the two stopping knots 11, 11 'ensuring the same person, and the second 11 is intended to cash, if any, belaying constraints.

Alternatively, as illustrated with reference to the second person 3 'on the left-hand part of FIG. 18, the person 3' can realize, according to a second configuration, first of all a stop node 12 on his harness 13 in an intermediate portion of the rope 2, and then recall the free end located between this intermediate fixing point and the free end 2D of the rope, opposite the other person 3 (or, more generally, at the opposite of the belay element 10 corresponding thereto), until the free end section of the rope is fully caught on the drum 4.

In either case, the rope 2 can be maintained, when it emerges from the drum, by any blocking or pinching means 41 which avoids inadvertent unwinding of the drum. By way of example, the pinching means may comprise one or more notches, preferably in V, cut in the upper edge of the outer cheek 15, as shown in dashed lines in FIGS. 7, 8, and 18.

In particular, in the first configuration (on the right), the two extremal sections of the soft strand coming out of the drum 4 to each reach a stop node 11, 11 'can each be locked in a separate notch 41.

Of course, the method according to the invention may also comprise a step (c) of destocking wherein the rings formed on the drum 5 are progressively released so as to recover the use of the soft strand 2B.

By way of example, this soft strand 2B can advantageously be used to raise the insured person after he / she has fallen into a crevice, the fall having first been stopped by the blocking of the connecting strand 2A, and the climbing can be ensured by an appropriate haulage using the reserve rope that formed the soft strand 2B. B 11642 Advantageously, the retractor according to the invention allows the wearer 3 to benefit at any time from a reserve of useful, well-ordered, non-tangled, permanently available rope, which is stored in a discrete space of such so that it does not obstruct it, does not hinder its movements, nor causes any inconvenience to its breathing or its displacements, and which can be mobilized quickly and without major effort or particular risk.

Said retractor allows in particular to the insured person to have an accessory that facilitates the storage operations, transport and management of the rope, especially when adjusting the length of the connecting strand.

In addition, the fact of winding the rope on a drum rather than on the bust advantageously makes it possible not to imprison the body, the clothes or the backpack of the wearer in the rope rings, which increases comfort and safety said carrier. B 11642 / FR
