Description

-1-

The present invention relates to a device actuated by the physical - motor force of an individual and for use in an aquatic environment; This device is a medium dedicated to promoting the propulsion of man in this aquatic environment and intended to be worn on the feet of a user. The exercise of an amplified displacement in the aquatic environment with regard to the portable pedestrian means operated muscularly is traditionally devolved to the tool - prosthesis called palm. The palm is therefore the closest referent of the device according to the invention and serves here as a counter point, because it constitutes this premium comparison tool useful to a better understanding of it. The device according to the invention is a system that allows an action representing an overall improvement to evolve in the aquatic environment and thus, mainly compared to the conventional operating medium known as palm; The latter, although offering the man convincing convincing gains in terms of autonomous propulsion, also determines the defects of use that the present device makes it possible to solve by making that it places in recourse as improvement and radical alternative, and this in particular in terms of hydrodynamics, because by its conformation, it prohibits any unnecessary loss and wastage of the aquatic fluid treated for propulsion, and thus decisively optimizes the efficiency from this propulsive point of view ; But still, that it allows to stem all "erratism" and loss of control related to the confrontation with the mechanical resistance of this fluid; All in what the action and movement of a palm, and more generally the movements of two feet shod with palms only allow very imperfectly.

The device according to the invention, unlike this classic and usual means that constitutes fins no longer appears in a manner so to speak flat horizontal and in the plane of the body, but unlike a analogically opposed, to qualify as vertical and thus placed on a 90 ° plane different from that of a palm. More specifically, while a palm unfolds and fits in this plane of the body, the device according to the invention, it is deployed and 2920999 -2-

is in its most characterizing part, in the axis of the plane of the articular fold of the leg and its knee and therefore, in the axis of the kick and the overall natural movement of ergonomic mobility and hydrodynamic penetration of the set of 5 this leg. It is therefore that, given this presentation exactly profiled in relation to the movement of the swimmer's leg in action that the device according to the invention is "split" literally the flows, or more exactly, the water bodies. In addition to making it possible to obtain improved hydrodynamics without major losses of the aquatic flows and, consequently, an increased yield in terms of speed withdrawn by a user, this profile can be a practical improvement able to leave a user to better penetrate in certain contexts such as wrecks, crevices of rocks, caves, or any other related obstacles that may arise; but still for example to evolve in places particularly provided with seaweed. Being in this way profiled in the true plane of leg movement and kicking, but still being worn on both feet in its generic use, allows the device to be put into action once. by each leg and in a classic movement of beats of these, (and thus of return and as "to the kicking"), not to induce an increase of between swirls in the spacing of 2 feet and their Immediate surroundings 25, swirls that produce in the case of 2 palms in action, an enter and superfluous movement of erratic incidence, with perfectly chaotic consequences and thus simply harmful to the most rational evolution of a user; There is thus laterally more space between each device equipping a pair of feet, which once put into action together (and so to speak "canned"), reduces the possibility of swirls and their parasitic effects and consequently too much lack of control towards the aquatic environment. In general, the device according to the invention consists of a footwear, the first part of it, continued by a second that we called the reactor. 2920999 -3-

The footwear is placed relatively in the axis of the separation interval of the walls of the channeling structure of the reactor. This reactor consists of two major parts; one that has been called from a generic generic structuring structure and the other according to the same generic generic reactive volume system. The channeling structure itself is generically composed of 2 parts; These two parts are in the form of two walls, which are relatively opposite and are therefore mounted relative to each other. The ratio of the dimensions characterizing this channeling structure and beyond the entire reactor, is fundamental to the identity of the device according to the invention; This in particular with regard to the dimensions characterizing the walls and in particular their "height" which must be sufficient, in particular with respect to the distance which separates them and which must constitute, in view of this "height", a space of separation relatively limited, thereby to form the channeling structure, where takes place intermediately the reactive volume assembly consisting of its plastic stops, the last elements of the reactor; plastic stops which must also determine, according to their length, a relatively "height" of the walls of the canalizing structure of the reactor; Similarly, the separation space of the walls of the channeling structure must provide a distance capable of allowing sufficient latitude for the installation, deployment and internal implementation of this reactive volume assembly, the description of which follows. -after. This separation distance between the walls can vary between different points and areas thereof; Similarly, these walls are not to be understood as necessarily flat but can adopt curves and cambers various and varied and this as well in terms of their length as in their "height" but also variations in term of thickness and may also include unevenness in their structures. The leading edges of these walls may not follow axes that continuous, but adopt breaks or hyphenation and other curvatures. As regards their length, 2920999 -4-

these walls can be of very variable dimensions. The reactive volume assembly as previously mentioned, is therefore located in the internal space separating the 2 walls of the channeling structure transversely. This set consists of voluminal elements separated from each other but unitarily coherent between them called plastic stops which react in concert with the aquatic mechanical flows that come to apply to it, and this from the physical - mechanical effort generated by the user of the device; These plastic abutments are therefore presented, and are shaped so as to treat these streams of water, flow of water that is printed to them and which they confront to reorient them relatively to the back of the direction in which one is heading ; They can be presented as relatively long bodies. These plastic abutments can be fixed in any location deemed useful in the range of the two walls of the channeling structure and in particular in the relatively median portion of the "height" of these walls of the channeling structure of the reactor that they connect to the wall. to one another by allowing the fastening; They have a "confronting" surface and "catch" profile so that the whole involved in the actuation of the device makes them capable of a sought-after and efficient reaction, considering that they must to have correlatively and at least in part a thickness sufficiently fine to allow them to bend and obtain a useful reactive and mechanical effect; Similarly, they will be sufficiently long and / or wide so as to again be able to "capture" the flows of water in general, and obtain the desired effect. In a way, and from a global point of view, the reactor, its elements, treat the flow of water that engulfs in the manner of a raz; Thus, the captive water, forced and clamped laterally and relatively lengthwise by the channeling structure is thus trapped and constrained by the reactive volume assembly and its plastic stops that treat it concretely, and finally allow the "acceleration" . 2920999 -5-

According to particular embodiments: the walls of the channeling structure are subdivided into pieces which are interconnected by joints; Thus, these articulations of wall pieces with a channeling structure make it possible to obtain a longitudinal "twist" or "bending" effect in the plane of the walls, which thus makes it possible to bond ergonomically, mechanically and flexibly to the waving movement of go and come printed by the swimmer and his legs in action; These joints connecting these subdivisions of the walls of the channeling structure into pieces are particularly suitable for equipping reactor models larger than a certain size. the reactor may comprise a reduced reactive volume assembly only to a single plastic abutment and this especially in view of the length chosen for the reactor. - The footwear can be "double" to accommodate two feet grouped together more or less close together. The prepositioning and orientation axis of the footwear in the vertical plane may allow any variation of orientation with respect to that of the reactor; In particular, for the sake of ergonomics, that of the latter and its components can be found placed in their entirety, in the relative continuum 25 of the average angle of the "kick" of the swimmer and its slope. the reactor may comprise, in its zone of junction with the footwear, a height difference in height, taking on the appearance of a sufficiently marked extension of its walls of channeling structures with respect to the place of the footwear 30 so that during the use of the device on the surface of the water in particular, the bulk of the reactor penetrates the latter deeper, thus risking to cause less parasitic effects, such as eddy, noise, etc., with the surface. the reactor can adopt a conformation in which its two major constituents merge with each other to form only one and the same part; in such a way that the reactive volume unit is no more than one 2920999 -6-

extension and remarkable prominence but merged with the channeling structure and its walls. the two walls of the channeling structure can be connected in places and in particular in certain continuums and / or 5 parts of their edges of attacks. walls of channeling structures that are additional to those of the generic structure can be added to somehow complement and intercalate and be placed between them; Therefore, this automatically conditions and authorizes the existence and / or the possibility of a "multiplication" of the number of reactive volume assemblies and their plastic stops capable of being placed between the new interstitial spaces thus created. the joints linking the wall pieces of the channeling structure between them may be in the form of axes, also called articulatory axes. - The joints can be "traverses" and thus connect from one end to each of the walls of the channeling structure and their pieces to the other; In the case of articulatory axes in particular, this "ferry" mode can accordingly and if necessary also pass through the plastic stops of the reactive volume assembly while being able to ensure potentially only the attachment. The joints linking the wall pieces of the channeling structure between them may be constituted by an articulatory mode operating "by folding" of material, which is in the form of articulatory folds, folds directly resulting from the structure of the walls of the channeling structure and which allow torsion or "bending" in the longitudinal plane. These articulatory folds, other than being derived from the material itself of the walls, may still be of a material nature different from that of the rest of the latter while remaining intimately connected therewith, they may thus adopt, for example, material qualities capable of promoting more flexibility and thus greater torsional yields; But still, always in order to arrive at a 2920999 -7-

increased level of flexibility able to bend these walls in the longitudinal plane, they may be an area using part or a whole thickness less than the average of the rest of them. 5 - the joints of the wall pieces of the channeling structure may associate rebound systems such as springs, interacting springs and dynamically between the pieces. This principle is particularly devolved to be attached to articulatory modes using axes or axial principles. the joints linking the wall pieces of the channeling structure may be constituted and rendered effective by articulatory axial stops acting in this way, according to several eccentric support points associated for a single articulatory focus. - The joints connecting the wall pieces of the channeling structure between them can associate a rebound system associated with these walls by connecting the pieces longitudinally between them; This system says elastic armatures are placed relatively along the wall pieces, and aimed to induce a dynamic effect to the process of articulation of those once the entire device is put into action. This system can be in one continuous piece, or in several pieces between several pieces; It forms, in addition to a rebound system, a coherent secondary articulatory system accompanying the movement printed by the swimmer. the channeling structure may comprise and be provided with so-called penetrating longitudinal members or super-hydrodynamic leading edges and which are placed longitudinally at the mouth of the entrances / exits of water of the channeling structure and in the separation interval of the walls thereof. These penetrator longitudinal members or even super hydrodynamic leading edges will have, in addition to a hydrodynamic role, a role of protection against external shocks. These will be fixed in particular to the channeling structure, thanks to extensions of material in 2920999 -8-

support, but still potentially in the shoes themselves. They may, in the case where the walls of the channeling structure are subdivided into pieces and thus provided with joints, or be of a material nature plastic 5 to constitute in themselves a longitudinal system able to twist to follow and obey the general twisting movement imparted by the actuation of the device. Otherwise, an articulatory rendering can also be obtained by means of articulatory fractures consisting of breaks of lesser thickness, such as permitted by notches or holes, for example, inscribed in the structure of these penetrating or super longer members. hydrodynamic leading edges and which, placed along these structures and in particular in the continuum of the joints assembling the 15 pieces of walls of the channeling structure between them, allow and / or facilitate the torsion of these penetrator or super-rim longitudinal members. hydrodynamic attack. the channeling structure may comprise micro-palm-like structures in the form of "spars" or "fins" of plastic nature which, arranged particularly on the outer side of the walls, will have the role of being able to increase and / or better control the mechanical action induced and / or sought after towards the aquatic environment. the reactive volume assembly can benefit, in the internal space of the channeling structure, from the presence of bumpers which, when the plastic abutments are put into action and close to the end of their path and their maximum bending limit, and this in one way or the other, are interposed as obstacles providing a final deformation plastic abutments that are thus "abut" by causing a bulge in their plastic structure, which ultimately leads to deflection of the water flow even more towards the back. These bumpers may be of the "ferry" type, and thus go from one of the walls to the other of the channeling structure. 35 - Very similarly to the previous embodiment, the inner zone of the channeling structure and its periphery may be equipped with baffles and

particularly, "cross-board" deflectors placed and interposed in the width of the channeling structure and therefore between the walls thereof where, in addition to acting as bumpers opposing the plastic stops of the assembly 5 reactive volume as previously, may extend the deviation of the water flow generated and resulting from the actuation of the latter. These deflectors can be either fixed or mobile, and this in particular being either "adjustable" by the action of man or be influenced in their mobility by the action 10 printer water flow once the device put in action ; but still, to be more or less flexible or rigid, and thus to associate several materials in their structures, and to benefit from varied cut-outs at their edges or even from internal cuts. The plastic stops of the reactive volume assembly can be present in their structure even in conformations of various internal and external shapes and cuttings, such as in particular provided with various borders, indented architectures, etc. The plastic stops of the reactive volume assembly can be present in their structure and their thickness in conformations of "volume" type such as "split" and unfolding on different levels. the reactive volume assembly may have one or more plastic stops constituting it which bear only on one of the internal faces of the walls of the channeling structure. In this way and correspondingly to this possibility, at least two plastic stops of this type can be mounted relatively "opposite" each other so as to "align" relatively, so that the space between them can be reduced to nothing and / or be left free and open more or less widely. These associations of several plastic stops of this type determine and together form synergic micro-systems unitarily coherent. The plastic stops of the reactive volume assembly can be "composite" and thus be composed of several materials with different mechanical qualities,

such as deformable plastic structures, flexible under the influence of water flows applied and printed, associated with more rigid bodies and thus less deformable. the reactive volume assembly and its plastic stops can be "one piece" and not so as to be a set of distinct complementary bodies acting together. This more complete homogeneity for an approaching result can be obtained and realized concretely from a single block fixed in the range of the walls of the channeling structure, having a more or less plastic and reactive nature, within which stops plastics will initially be part of its mass and which, by their conformation will be able to interact mechanically by the action and the aquatic environment. - the junction between the footwear and the reactor can be "adjustable" and not fixed and irremovable at the beginning, this to allow to change and adjust in the vertical plane the orientation angle of the footwear with respect to that of the reactor ; This junction may thus be constituted by a "bipolar" or "fork" type articulation module 20, which is currently called "bipolar" axial connection, and which is therefore "adjustable"; The term "bipolar" means that it is an articulatory assembly constituted by two points of articulation which are distinct from one another but serve a single axial alignment, and which thus gives one and the same coherent whole; This articulatory assembly of axial connection type differs mainly from the joints of the wall pieces of the channeling structure of the reactor, and is therefore differently named by the fact that it supports an intermediate object and encloses an "outside" object which in this case , regarding the device is here the footwear part. This "bipolar" axial joint or link module is thus made "adjustable" via fastening systems such as, for example, screws and which are therefore joined by concomitant threads; Likewise, these "bipolar" and "adjustable" axial connections may be terminated by fastening washers assigned to associate, in particular

fixing systems, and thus in this case screws for example. -The junction between footwear and reactor can also be made "adjustable", not to be fixed at the start definitively, according to the principle of several "centers" junction and "adjustment" associated in particular in order to have the benefits of "a" fixation more assured while still allowing to vary the angle of incidence of the footwear relative to the general angle of the reactor in the vertical plane. These "centers" or "fixation levels" are decomposed into a first junction such as for example by a "bipolar" and "adjustable" axial connection; "bipolar" because constituted by two axial points which are distinct from one another and in the service of the same axis, and rendered "adjustable" by means of a suitable fixing system such as for example by screws, and which therefore constitutes a first junction or a first "level of attachment" that is associated with a second junction, such as by notches and cleats bonds for example which it allows to ensure the bulk of the "adjustment" while allowing a secure fixation of all . A graded notch system, associating in itself the presence and the complementary action d <notches that will be dedicated to accommodate cleats to block them in their breasts, one or the other of these two elements may be connected alternately to from the footwear or the reactor. The junction between the footwear and the reactor can be constituted by a hinge module of "bipolar" axial link type and of a nature that is no longer "adjustable" this time, but specifically "mobile" and dynamic; "bipolar" because constituted by two axial points distinct from each other, put at the service of the same axis, and thus made "mobile" and dynamic through the addition of rebound systems, such as for example as here via springs, springs joint axial mechanisms of these connections and interacting between the parts footwear and reactor. The junction between footwear and reactor can also be made "mobile" and dynamic according to the principle of several "centers" or "levels" of mobility associated; 2920999 - 12 -

Thus, a "bipolar" and "mobile" axial connection may constitute a first "center" of junction and articulation; ("bipolar" because it consists of two axial points that are distinct from one another but serve the same axis, and "mobile", from being left free from any restraint); This axial connection "bipolar" and "mobile" thus forms a first "center" junction and articulation that is associated with a second, constituted for example by dynamic links pushers, which allow, via rebound systems, 10 materialized for example by springs and coupled complementarily to the pushers come to somehow "confront" and interact synergistically with each other and produce a dynamic mobility effect dispensed to the entire juncture footwear - reactor; The pushing elements and springs that can be placed can be attached alternately from the footwear or the reactor. - The junction between footwear and reactor can be constituted by a "continuous" and "adjustable" axial connection without hyphenation or subdivisions (caused in this case intermediately by an "obstacle" or an "object", as here, a footwear) ; This type of junction can be assumed by a "ferry" axis, attaching to the passage an extension of material from the footwear part which indirectly allows the connection to the reactor part. This axial connection thus "continuous" through a "ferry" axis is made "adjustable" via a fastening system, for example by means of a screw system, which allows to adjust the angle of incidence of the footwear portion relative to the general orientation angle of the reactor in the vertical plane. - The junction between footwear and reactor can be constituted by a "continuous" and "mobile" axial connection without hyphenation or subdivisions (caused in this case intermediately by an "obstacle" or an "object", as here a footwear); This type of junction can be assumed by a "ferry" type axis, attaching to the passage an extension of material coming from the foot part which allows it indirectly.

the connection to the reactor part. This axial connection, thus "continuous" through a "ferry" axis, is rendered "mobile" and dynamic by the addition of rebound systems such as, for example, one or more springs mounted in connection with this link. axial "continuous" assumed via a axis type "ferry". - The footwear parts and reactor can associate a so-called armature part, joining the rest of the device to its footwear and / or reactor parts, but especially at their 10 junctions, and which can take place mainly on the calves of the swimmer. These reinforcements are intended to support and accentuate the general action of the device in terms of control towards the aquatic environment, but also in terms of efficiency and unobstructed power, and this thanks to a reinforced support that they provide. towards the rest of the device as a whole once the swimmer's body is in action; These reinforcements will have to denote a conformation associating particular mechanical qualities and sufficient in terms in particular of rigidity and which are able to allow a convincing result of action. These frames are based on the legs, either by fixing them and / or threading them, and can be placed therein in the extreme limits thereof, this, from the perimeter of the foot to higher in the legs, the calf to be their most obvious generic site focus for them to "base" there. This armature part will be connected in support of the device by one or more junction points sufficiently "mobile" to give free rein to the movement while ensuring its reinforced mission of maintenance; These articulation junction points may be, for example, an axial connection "bipolar", "bipolar" because constituted by two points of articulation distinct from one another, that separates one or more objects that it supports between its two hinge points that serve and together determine a single consistent axial alignment. 35 The means or means they will have to be attached to the leg may vary. 2920999 - 14-

- The entire device and particularly the body of the walls of the channeling structure may include openings or openings, of varying shapes and sizes allowing water flows in / out. 5 - the footwear can vary in its footwear size and thus be more or less "low" or "high", this, from the level of the feet upwards in the legs, and in particular up to the level of the calves. - The footwear may include various systems 10 of openings - closures, which can make them "adjustable" in terms of level of attention to the foot and leg; auxiliary systems of openings - closures arranged in a manner that may vary, but may in particular be positioned on the sides and / or in front; Opening-closing systems such as by clips, laces (in "rubber" or in any related "plastic" material), straps, snaps, velcro, zippers, zippers, buttons, etc. -the footwear can be "adjustable" in the manner of some fins; The footwear is relatively gaping open and 20 on its rear portion and have an adjustable tab encapsulating and "belting" at and around the regions of the Achilles tendon and heel; This tongue system, removable or not, can finally be adjusted, and this in particular thanks to, for example, webbing systems and / or adapted clamping, and to maintain the entire foot in the footwear. - The footwear part will allow to respect the physiological specificity, and thus formal each foot and therefore, can be conformed to accommodate a right foot 30 specifically, but still, to accommodate a left foot specifically. the plastic stops constituting the globally reactive volume assembly can adopt any orientation considered useful in the internal space of the walls of the channeling structure, individually or collectively; this also applies to the particular embodiment implementing a reactive volume assembly that is "in one piece" 2920999 - 15 -

and, specifically here, with regard to the forms of plastic abutments registered and understood in its mass. the plastic abutments constituting the overall reactive volume assembly, may adopt any locations deemed useful for the exercise of the device in the internal space of the walls of the channeling structure, this also being valid for the particular embodiment implementing a reactive volume assembly that is "in one piece" and, specifically here, in terms of the intended forms 10 and associated thereto with its mass. - The channeling structure can in its "height" and on several levels or "floors" (and at least more than one), accommodate a variable number of superposed plastic stops. According to a cross-sectional view of the reactor, the plastic stops of the reactive volume assembly can adopt, in a sufficiently clear manner, a positioning that is not perpendicular to the mean separation plane of the channeling structure and its walls, but angle or "slope" different; This in particular in the case of the particular embodiment having plastic abutments that are attached to only one of the walls of the channeling structure. plastic stops of the reactive volume assembly can be attached to the body of the footwear part, in order to usefully limit in size and length the entire device and especially its reactor part, by using a useful space. - The reactor part may be removable from the footwear part and fix or subtract thereof, from a junction module having one or more levels of fixing, being provided with fastening systems such as allowed for example by assistant screws. - The walls of the channeling structure can determine a different shape relative to each other, and this in particular, both in terms of profiles and in terms of cutting. All joints using axial systems such as hinge joints or axial links, or similar, such as stops 2920999 - 16-

axial can associate with their respective axes, one or more mechanisms of the type bearings, and in particular so-called "ball bearings", to facilitate mechanical mobility. These bearing systems may be of a nature that does not allow corrosion or mechanical pollution from the outside which would come in particular from the marine environment, such as sand, particles, etc. The indexed drawings illustrate the Invention 1 represents the device of the invention in perspective.

FIGS. 81 and 82 show, successively in plan view and in section, a section of the reactor of the device according to the invention describing a variant which has the reactive volume assembly and its plastic abutments which are "in one piece", in a single homogeneous block, and not in such a way as to constitute a set of distinct complementary bodies acting as preservatives, Figures 83 and 84 represent successively in order in profile 25 and in top view, a variant of the device according to the invention, describing the junction of the footwear and reactor parts provided with an axial connection "bipolar" and "adjustable"; "bipolar" because constituted by two axial points distinct from one another and in the service of the same axis, and made "adjustable" via a suitable fastening system, in this case here screws for example, vary the angle of incidence of the footwear relative to the general angle of the reactor in the vertical plane. FIGS. 85 and 86 show successively in profile view 35 and in view thereof, a variant of the device according to the invention, having the junction of the footwear and reactor parts according to a "continuous" and "adjustable" axial connection, permitted and 2920999 - 25 -

materialized in this case and for example here, by a "ferry" axis, taking care of the footwear part by making it possible to adjust the angle of incidence relative to the general angle of the reactor in the vertical plane, via a suitable fastening system, in this case screws for example. FIGS. 87 and 88 show, successively in profile view and in plan view, a variant of the device according to the invention, describing the junction of the footwear and reactor parts produced and made effective along several "centers" of junction, in particular in order to to have the benefits of a better secured fixation while still making it possible to vary the angle of incidence of the footwear with respect to the general angle of the reactor in the vertical plane. These "centers" or "fixation levels" are decomposed into a first junction such as for example by a "bipolar" and "adjustable" axial connection; "bipolar" because constituted by two axial points distinct from one another and serving on the same axis, and made "adjustable" via a suitable fastening system such as for example by screws, and which is therefore a first junction or a first "level of attachment" 20 that is associated with a second junction, such as by notches and cleats bonds for example which it allows to ensure the bulk of the "adjustment" while allowing a secure attachment of the 'together . Either of these two elements can be attached alternately from the footwear or the reactor. Figures 89 and 90 show successively in profile and in top view, a variant of the device according to the invention, describing the junction of the footwear parts and reactor provided with an axial connection "bipolar" and "mobile"; "bipolar" 30 because constituted by two axial points distinct from one another and serving the same axis, and thus made "mobile" and reactive through the addition of rebound systems, such as for example as here springs, springs joint to the axial mechanisms of these connections. Figures 91 and 92 show successively in profile view and in top view, a variant of the device according to the invention, describing a "movable" connection of the parts 2920999 - 26 -

  footwear and reactor made and made effective according to several "centers" junction associated and "mobile" together, in particular, in order to have the benefit of "a" junction "mobile" and better assured; These "centers" decompose into a first junction such as formed by a "bipolar" and "mobile" axial link; "bipolar" because constituted by two axial points distinct from each other and serving the same axis, and "mobile" from being left free of any restraint; This axial link "bipolar" and "mobile" that is associated with another "center" or "level of mobility", consisting for example of dynamic links pushers that they actually allow a set - rebound system, materialized by springs (shown for better readability in transparency in the figure), springs coupled to pushers, to produce a dynamic mobility effect dispensed for the entire footwear-reactor junction; These pushing elements and springs can be attached alternately from the footwear or the reactor (presently in these figures, the push member fits from the footwear part while the springs are inscribed from the reactor part). Figure 93 shows generically a side view of a variant according to the device of the invention; This describes a frame to be placed on the swimmer's leg, and in particular to "base" on his calf, and which is connected to the rest of the device by a junction which allows, at the same time as a strong hold, also minimal movement; This junction is constituted for example by a "bipolar" axial connection; "bipolar" because constituted by two axial points distinct from one another and the service of the same axis. If the junction between the parts footwear and reactor is not fixed, and therefore is accordingly "adjustable" or "mobile", this junction can be connected to junction points already joining the footwear and reactor parts of the device between them. With reference to these drawings, the device comprises two major parts, a footwear part (A) and a reactor part (B); The latter has a set called 2920999 - 27 -

  channeling structure (1) formed by two walls each mounted relative to each other and between which is joined 1 <reactive volume assembly and the plastic stops (2) which constitute it and which react dynamically 5 by their mechanically plastic nature during the activation of the device. In the embodiment according to FIGS. 9 and 15 in particular, the walls of the channeling structure (1) can be broken down into pieces articulating with one another by means of articulations (3) that can be embodied by articulatory axes; In the embodiment according to Figure 10, these joints (3) can also be cross-type (4) so as to connect from one side to the walls of the channeling structure (1) and their pieces between them. The wall pieces of the channeling structure (1) can be made remarkable and "legible" by their separation zones also called articulation recesses (5); In the embodiment according to FIGS. 22 and 23 spring-type rebound systems (6) can be associated with the peripheries of the articulations (3) and therefore with these articulating axes pieces of walls of the channeling structure (1). . In the embodiment according to FIGS. 24 and 25, an alternative system of articulations (3) of pieces of walls of the channeling structure (1) between them, said axial abutments can be used and be provided with incidental systems. rebounds (6), and here in this case springs, again allowing, in addition to producing a mechanically appreciable rebound effect, to allow a better constrained and dynamic axial tracking. In the embodiment according to Figures 26, 27 and incidentally 28, the articulatory mode of the walls of the channeling structure (1) can vary and be replaced by joints (3) in the form of a structural folding system called system by articulatory folds or articulatory folds subdividing and articulating the wall pieces of the channeling structure (1) between them and articulating them. In the form of 2920999 - 28 -

embodiment according to FIGS. 29 and 30, another variant of rebound system (6) of the elastic reinforcement systems type can be added to the walls of the channeling structure (1) all along or in a piecemeal fashion, and produce and form, in more than a rebound system (6), an articulatory system or articulations, secondary coherent accompanying the movement printed by the swimmer. These elastic reinforcements are more or less superficial in body or interlock with the walls of the channeling structure (1) and their pieces. In the embodiment according to FIGS. 31 and 32, and according to a variant of the device of the invention, longitudinal members or super hydrodynamic leading edges (7) can take place around the inlets and outlets of water. walls of the channeling structure (1) and serve as bumper protections against the environment that may be encountered, as well as office structures to improve the hydrodynamics of the device; These hydrodynamic penetrating or super leading edge longitudinal members (7) can exploit, at least in part, the same qualities in terms of mechanical and dynamic input as those of rebounding systems (6) referred to as elastic reinforcements presented above. that is to say that they themselves can constitute by their constitutive nature and / or plastic material a dynamic system capable of rebounds; In the embodiment according to FIGS. 33, 34 and 35, their folding can be facilitated by virtue of the articulatory rupture mechanism consisting of smaller thickness cuts and / or truncations inscribed in the structure thereof. In the embodiment according to FIGS. 37, 38 and 39, plastic spars or fins of plastic nature, to be understood by micro-palmating structures (8), can be placed along the walls of the channeling structure (1) and allow a mechanical effect of support and support, able to produce increased control of the device according to the invention towards the aquatic environment. In the embodiment according to FIGS. 55 and 56, stops (9) can be placed in the range of the walls of the channeling structure (1) of the reactor (B) 2920999 -29-

in order to stop the travel of the plastic stops (2) of the reactive volume assembly and, simultaneously, by putting into stress the presence of these stops (9), to generate a residual mechanical deformation of these, in such a way that the flow of water from the action is finally further diverted and channeled backwards towards which direction the swimmer using the device of the invention is heading. In the embodiment according to FIGS. 57 and 58, and for a result similar to that of these stops (9) but more consistently in terms of the effect of removing the deflection of the streams of water, and still in the interval of the walls of the channeling structure (1), baffles (10) can be placed at the end of travel plastic stops (2) to deviate more fully the flow of water generated by them. If the plastic abutments (2) can assume a variety of shapes, they can also be of "composite" configurations and in the embodiment according to Figs. 77 and 78, thus include, in an associated manner, flexible and "deformable" parts. (11) and other "stiffer" portions (12) to remove an increased mechanical effect. The footwear junction (A) and reactor (B) may, if it is not fixed and predetermined, be in one or more "adjustable" junction points and / or be in one or more "movable" points. junction; This footwear junction (A) - reactor (B) is seen to act by axial connections (13), which differ mainly from the joints (3) of the wall pieces of the channeling structure (1) of the reactor (B), in that that they have to take charge of an object "external" to their "origin", and which in this case with regard to the device is the footwear part (A). Thus, in the embodiment according to FIGS. 83 and 84, a junction formed by a "bipolar" axial connection (13) constituted by two axial points that are distinct from one another and serve on the same axis, are made "adjustable" by a fastening system (14) such as for example screws, which concomitantly join threads (15); 2920999 -30-

Similarly, these axial connections (13) "bipolar" may be terminated by securing washers (16) devolving to be able to associate in particular the fastening systems (14), and therefore for example and in this case screws. These "bipolar" axial connections (13) which therefore constitute the same junction constituted by two axial points which are distinct from one another and which serve the same axis, can be replaced by a junction consisting of a connection point continuous, which will be called axial connection (13) "continuous" or "transverse"; "cross" or "continuous" and without subdivisions in its joining principle because it is constituted by a axis "ferry" taking care of the passage part footwear; In the embodiment according to FIGS. 85 and 86, this "continuous" or "transverse" axial connection (13) can be "adjustable" on the one hand, again a fastening system (14) such as constituted for example by screw, that concomitantly join the screw threads (15), and again, be terminated by securing washers (16) assigned to include in particular the fastening systems (14), and therefore in this case and by example of screws. In the embodiment according to FIGS. 87 and 88, the junction between footwear (A) and reactor (B) can be made "adjustable" according to the principle of several sets or "centers" or even "levels of fixation" and of associated setting; Thus an axial connection (13) "bipolar", "adjustable", attaching a fastening system (14) such as for example by screw to its principle, may constitute a first set or "center", complementarily associating a second "center" or "fixation level", for example, via a system that will be called graded notch system, associating the presence of notches (18) and the complementary action of stops (19) intended to be received and blocked in within them; either of these two elements can be attached alternately from the footwear or the reactor. In the embodiment according to FIGS. 89 and 90, the junction between footwear (A) and reactor (B) may be furthermore 2920999.

constituted by an axial connection (13) "bipolar" no longer "adjustable" but specifically made "mobile" and dynamic, and thus comprise rebound systems (6) as constituted by springs associated with this axial connection (13) " bipolar ", and interacting between footwear (A) and reactor (B). In the embodiment according to FIGS. 91 and 92, this junction between footwear (A) and reactor (B) can also be made "mobile" and dynamic according to this principle of several associated "centers" or "mobility levels". ; Thus, an axial connection (13) "bipolar" of a type "not adjustable" this time, but left free, and thereby with no associated fixing system, can constitute a first "center", associating with a second ; This second dynamic "center" or "level of mobility" includes an assembly - rebound system (6) as permitted for example by springs, springs coupling complementarily to pushers (20) with which they come in some way. to "confront" and interact dynamically and synergistically with each other; Each of these two elements can be attached alternately from the footwear (A) or the reactor (B). In the embodiment according to FIG. 93, the footwear parts (A) and the reactor (B) can associate a so-called armature part (C), joining the footwear part (A) and / or the reactor (B) in particular to their junctions. , and which is to be placed on the swimmer's leg and in particular to "base" on the calf of the swimmer; This is intended to support and accentuate the general action of the device in terms of efficiency and 30 power released through a strengthened maintenance of the device as a whole to the body of the swimmer once it is put in place. action; This reinforcing part (C) is thus connected to the device by one or more junctions, and this in particular in a practical way and associated with the junction points already serving to connect the footwear parts (A) and reactor (B) to each other, and this in particular via an axial connection (13) "bipolar" which can serve as a junction point; 2920999 - 32 -

On the other hand, if the junction between the footwear parts (A) and the reactor (B) is fixed, and thus "non-adjustable" or "movable", the junction (s) of this armature part (C) connecting it to the rest of the device made by means of a junction, for example of the "bipolar" axial connection type (13), which must, at the same time as being of a sufficiently "mobile" nature and allowing a minimum sufficient movement, be capable of ensure strong support, especially at the level of the swimmer's ankle joint. 10 The means or means they will have to be fixed or restrained in the leg may vary. According to non-illustrated variants, all joints (3) which are similar to axial systems (including the axial abutments) and therefore including the axial connections (13), can associate with their respective axes one or more mechanisms of the type bearings, and in particular so-called "ball bearings", in order to facilitate mechanical mobility. According to a variant not illustrated, the system of joints (3) of the wall pieces of the channeling structure (1), called by articulatory folds can see its "folds" to move towards the inside of the reactor rather than bulging outwards . According to a variant not illustrated, the stops (9) may be "cross-bridges", in the manner of articulations (3) of the type articulating axes of the same principle (4) already mentioned, and therefore, connect a wall of the channeling structure ( 1) to the other. According to a variant not illustrated, the type of footwear juncture (A) - reactor (B) consisting of a continuous axial connection (13) or "transverse", can be made "mobile" also and this, via bounce systems (6) and for example by means of one or more additional springs associated with this "continuous" or "transverse" axial connection. "According to a variant not illustrated, and in the case where the junction between footwear (A) and reactor (B) is made "adjustable" according to the principle of several "centers" or "levels of 2920999 - 33 -

fixation "associated, and in particular through an axial connection (13)" bipolar "," adjustable ", complementarily combining a system called graded system with notches, this axial connection (13)" bipolar "," Adjustable "5 can be replaced by one of a type" not adjustable ", and thus having no" fixing systems "associated.Un variant not shown, the reactor part (B) will be specifically" removable "part (A) and a fastening system (14) as permitted by screws at their junction.As a non-limiting example, the interval between the walls of the channeling structure may be the order of 5 cm, the "height" of these walls of the order of 15 cm, and their length from the footwear of the order of 15 cm 10 up to 60 cm see more; the size and number plastic stops being fixed, even if it is not obligatory relatively to the rest of the reactor and thus the channeling structure and its walls; By way of non-limiting example, these may have an average width of the order of 5 cm and a length of the order of 5 to 15 cm for example. The device according to the invention is particularly intended for underwater sports, but also, rescue at sea and along the coast.

This footwear part (A) can thus meet and be conformed to the image of the specific forms of each of these asymmetrical parts of the human body, respecting for example the hollow shapes of the respective plantar arches punctually. 20 20) Device according to any one of the preceding claims characterized in that the reactor part (B) is removable and specifically can be fixed or subtracted from the footwear part (A) (and therefore reciprocally) through one or more points of fastenings actually embodied by one or more suitable fastening systems (14) as permitted by screws for example; these points of attachment or binding that may actually qualify such fastening systems (14), can be placed in "links" between the channeling structure portion (1) of the reactor (B) and the footwear 30 (A), the solidarisant or allowing the opposite to make these parts separate. 21) Apparatus according to any one of claims 1 to 19 characterized in that the junction between the footwear (A) and reactor (B) is "adjustable" to allow to change in the vertical plane the angle d orientation of one of these parts with respect to the other; This, for example, by means of an axial link type coupling module (13) "bipolar" or "fork" connecting them; This axial connection (13) "bipolar" or "fork" is constituted by two points of articulation distinct from each other, which enclose and support between them the footwear part (A) this serving and determining together a single coherent axial alignment; This junction between the footwear parts (A) and reactor (B) is made "adjustable" by one or more fastening systems (14) such as using for example screws associated with it, which can also allow 10 potentially to these two parts footwear (A) and reactor (B) to become removable relative to each other. 22) Device according to any one of claims 1 to 19 characterized in that the junction between footwear (A) and reactor (B) is made "adjustable" to allow to change in the vertical plane the angle of orientation of one of these parts relative to the other through and according to the principle of several associated "centers" or "attachment levels"; These "centers" or "attachment levels" are broken down, for example, into a first junction such as the "bipolar" and "adjustable" axial linkage type (13); "bipolar" because constituted by two points of articulation distinct from each other, which enclose and support between them the footwear part (A), this serving and determining together a single coherent axial alignment; First "center" made "adjustable" via one or more fastening systems (14) adapted such as using for example screws associated with it, and that can be added to other "centers" junction and in particular a second such as served for example by a junction type of notches and cleats which includes the presence and the complementary action of notches (18) which are destined to receive cleats (19) to block them in their breasts ; either of the latter two elements can be attached from the footwear (A) and / or the reactor (B); The fastening system or systems (14), such as using, for example, screws which are associated with them, can therefore also allow these two parts of footwear (A) and reactor (B) to become removable relative to one another. other 2920999 -41- potentially. 23) Device according to any one of claims 1 to 19 characterized in that the junction between footwear (A) and reactor (B) is "mobile"; Thus it may be constituted for example by an axial link type coupling module (13) "bipolar" and of "mobile" nature; "bipolar" because constituted by two axial points distinct from each other, put at the service of the same axis; mobility can be made dynamic by the addition of 10 rebound systems (6), such as for example via springs, springs potentially joint axial mechanisms of this type of connection exemplary and interacting between the footwear (A) and reactor (B). 24) Apparatus according to any one of claims 15 to 1 to 19 characterized in that the junction between footwear (A) and reactor (B) is made "mobile" according to the principle of several "centers" or "levels of mobility "associates; These decompose for example into a first "center" junction and articulation such as taking for example the form of an axial connection (13) "bipolar", "mobile"; "Bipolar" because constituted by two points of articulation distinct from each other, which enclose and support between them the footwear part (A) this serving and determining together a single coherent axial alignment, and "mobile" because of being left free from any restraint; Axial connection (13) "bipolar", "mobile" thus associating with other "centers" of mobility, and such as for example to a second "center" which in this case may be "dynamic" and constituted for example by dynamic links by pushers, and formed of a set - rebound system (6) as permitted by springs coupling complementarily to pushers (20) with which they come to "confront" and interact dynamically and synergistically to each other;
