Description

La présente invention concerne une palme de natation, notamment destinée à des activités de loisirs. Elle concerne plus particulièrement une palme dont la partie chaussante est ajustable en fonction de la pointure du pied de l'utilisateur. Cette palme est destinée à équiper des individus adultes ou enfants pour des activités nautiques de loisirs, telles que la plongée, la chasse sous-marine, l'apnée, la nage, le bodyboard ou encore la randonnée subaquatique dénommée snorkeling. Il est cependant envisageable que cette même palme soit utilisée dans des activités professionnelles diverses, par des pêcheurs ou plongeurs, ou encore dans des activités de sauvetage en mer.The present invention relates to a swimming fin, particularly intended for leisure activities. It relates more particularly to a palm whose footwear is adjustable according to the size of the foot of the user. This palm is intended to equip adults or children for recreational water activities, such as diving, spearfishing, snorkeling, swimming, boogie boarding or snorkeling. It is conceivable, however, that this same fin can be used in various professional activities, by fishermen or divers, or in rescue activities at sea.

Une palme de natation est composée essentiellement de deux parties, à savoir la partie chaussante qui est destinée à recevoir le pied de l'utilisateur et la partie d'appui dont l'avant comporte la voilure de la palme et dont l'arrière réceptionne la partie chaussante. En fonction des différents types de palmes, la partie chaussante et la partie d'appui sont soit indépendantes et détachables l'une de l'autre, soit fixées solidement l'une à l'autre soit encore complètement intégrées. Dans ce dernier cas, la palme est une pièce monobloc dans laquelle les deux parties chaussantes et d'appui sont dans le même matériau.A swimming fin is essentially composed of two parts, namely the footwear portion which is intended to receive the foot of the user and the support part whose front has the wing of the fin and whose rear receives the footwear part. Depending on the different types of flippers, the footwear part and the support part are either independent and detachable from each other, or firmly attached to one another or completely integrated. In the latter case, the palm is a one-piece piece in which the two parts footwear and support are in the same material.

S'agissant de la partie chaussante, il est impératif qu'elle maintienne correctement le pied lors de l'utilisation, compte tenu des contraintes exercées lors des battements du pied. Si la partie chaussante n'est pas convenablement serrée autour du pied, il y a un risque majeur que la palme se désolidarise du pied lors de l'utilisation.Regarding the footwear part, it is imperative that it keeps the foot properly during use, given the constraints exerted when the foot beats. If the footwear is not properly tightened around the foot, there is a major risk that the palm disengages from the foot during use.

Dans un premier type de palme, la partie chaussante est constituée d'un chausson qui est assujetti à la partie d'appui et qui entoure complètement le pied de l'utilisateur à savoir à la fois le talon, la plante du pied et le cou-de-pied. Un tel chausson est réalisé en matière plastique et élastique, généralement en élastomère, de manière à pouvoir être déformé pour permettre l'insertion du pied et de manière à assurer un serrage efficace du pied une fois celui-ci positionné à l'intérieur du chausson. On constate que l'introduction du pied dans ce chausson n'est pas très pratique, l'utilisateur étant obligé de tirer fortement sur les bords de la partie chaussante pour déformer celle-ci et pouvoir insérer le pied. De plus une telle palme de natation est proposée pour une pointure c'est-à-dire une taille de pied déterminée, l'adaptation à une pointure légèrement supérieure ne pouvant intervenir que grâce à la déformation du matériau utilisé pour réaliser le chausson, avec corrélativement une augmentation du serrage du pied et éventuellement une gêne pour l'utilisateur du fait d'un serrage trop important. Enfin, la qualité du serrage du pied, alors même que l'utilisateur a la pointure requise, peut varier en fonction de la forme de son cou-de-pied, un utilisateur ayant un fort cou-de-pied ayant son pied trop fortement comprimé alors qu'un utilisateur ayant un faible cou-de-pied pouvant voir son pied flotté légèrement dans la partie chaussante.In a first type of palm, the footwear consists of a slipper that is subject to the support portion and completely surrounds the foot of the user to know both the heel, the sole of the foot and the neck -of foot. Such a liner is made of plastic and elastic, generally elastomer, so as to be deformed to allow the insertion of the foot and to ensure an effective tightening of the foot once it is positioned inside the liner. It is found that the introduction of the foot in this shoe is not very practical, the user being forced to pull strongly on the edges of the footwear to deform it and can insert the foot. In addition, such a swimming fin is proposed for a size, that is to say a determined foot size, the adaptation to a slightly larger size can only intervene thanks to the deformation of the material used to make the shoe, with correlatively an increase in the tightening of the foot and possibly an inconvenience for the user because of too much tightening. Finally, the quality of the tightening of the foot, even when the user has the required size, may vary depending on the shape of his instep, a user having a strong instep having his foot too strongly compressed while a user with a low instep can see his foot floated slightly in the footwear.

Dans un second type de palme de natation, la partie chaussante ne comporte qu'un demi chausson, assujetti à la partie d'appui, qui n'entoure que l'avant du pied incluant le cou-de-pied et la partie avant de la plante du pied. Dans ce cas, la partie chaussante comporte également une bande élastique, prolongeant le demi chausson en sorte d'enserrer partiellement l'arrière du pied. L'élasticité de la bande arrière est mise à profit pour permettre l'utilisation d'une palme ayant une pointure donnée, par des utilisateurs ayant un pied légèrement plus grand que la pointure en question. Néanmoins ceci n'empêche pas l'inconvénient du serrage trop important au niveau du cou-de-pied, enserré dans le demi chausson. De plus, du fait que la bande a une largeur relativement faible, le serrage complémentaire au niveau de l'arrière du pied peut également être une gêne pour l'utilisateur.In a second type of swimming fin, the footwear has only half a slipper, subject to the support part, which surrounds only the forefoot including the instep and the front part of the foot. the base of the feet. In this case, the footwear also has an elastic band, extending the half liner so as to partially enclose the back of the foot. The elasticity of the back band is used to allow the use of a palm having a given size, by users having a foot slightly larger than the size in question. However this does not prevent the disadvantage of too much tightening at the instep, enclosed in the half slipper. In addition, because the band has a relatively small width, the additional tightening at the back of the foot can also be a nuisance for the user.

Ce dernier inconvénient peut être évité en mettant en oeuvre une bande arrière qui est équipée d'une boucle de réglage, permettant d'ajuster la longueur de ladite bande et donc le serrage de celle-ci. Néanmoins, cette disposition particulière n'apporte pas de solution au problème du serrage trop important au niveau du cou-de-pied qui est dû au fait que le demi chausson est une pièce préformée une fois pour toutes, ce problème pouvant apparaître pour des personnes ayant la pointure adaptée à celle de la palme en fonction de leur configuration de cou-de-pied mais surtout pour des personnes voulant utiliser une palme ayant une pointure donnée alors qu'elles ont une pointure supérieure à celle-ci.This last disadvantage can be avoided by implementing a rear band which is equipped with an adjustment loop, making it possible to adjust the length of said band and thus the clamping thereof. However, this particular provision does not solve the problem of excessive tightening in the instep that is due to the fact that the half slipper is a preformed piece once and for all, this problem may appear for people having the size adapted to that of the palm according to their configuration of instep but especially for people wanting to use a palm having a given size when they have a size greater than this one.

On a déjà proposé, par le document US.5.259.798 , une palme dans laquelle la partie chaussante est fermée sur l'arrière en sorte de maintenir le talon et est ouverte d'une part sur l'avant pour laisser le passage aux orteils et d'autre part sur le dessus en sorte de ménager un rabat qui permet de faciliter l'introduction du pied et également de régler le serrage au niveau du cou-de-pied grâce à des sangles de fixation. L'utilisateur peut donc ajuster le serrage de la partie chaussante au niveau de son cou-de-pied. De plus, en théorie, cette palme, prévue pour une pointure donnée, devrait pouvoir être utilisée pour des pointures supérieures dans la mesure où la longueur excédentaire de pied peut dépasser librement à travers l'ouverture formée à l'avant de la partie chaussante.It has already been proposed, by the document US.5.259.798 , a palm in which the footwear is closed on the back so as to maintain the heel and is open on the one hand on the front to leave the passage to the toes and on the other hand on the top so as to spare a flap which facilitates the introduction of the foot and also to adjust the tightening at the instep by means of fastening straps. The user can therefore adjust the tightening of the footwear part at his instep. Moreover, in theory, this fin, provided for a given size, should be able to be used for larger sizes since the excess length of foot can freely pass through the opening formed at the front of the footwear part.

Cependant le demandeur a constaté que dans ce cas le maintien du pied n'était plus assuré dans de bonnes conditions, dans la mesure où le rabat et les sangles de fixation réalisent le serrage dans une zone du pied qui est différente selon la pointure de l'utilisateur.However, the Applicant has found that in this case the maintenance of the foot was no longer ensured in good conditions, insofar as the flap and the fastening straps make the tightening in an area of the foot which is different according to the size of the shoe. 'user.

On a également proposé par le document US-2005/221698 , une palme qui présente des caractéristiques et inconvénients similaires à celles de la palme décrite dans le document US-5.259.798 , à la différence près que la partie chaussante est encliquetable dans une zone de réception agencée sur une partie d'appui supportant une voilure. Cette partie chaussante est fermée sur l'arrière en sorte de maintenir le talon et comprend des rabats latéraux qui, en position rabattue, enveloppent le cou-de-pied ainsi que les orteils. Par ailleurs, des sangles de fixation sont prévues sur la partie d'appui et permettent de régler le serrage des rabats au niveau du cou-de-pied. Ces sangles réalisent toutefois un serrage dans une zone du pied qui diffère selon la pointure de l'utilisateur, n'assurant par conséquent pas le maintien du pied dans de bonnes conditions.It was also proposed by the document US 2005/221698 , a palm that has similar characteristics and disadvantages to those of the palm described in the document US 5259798 , with the difference that the footwear part is snap-fit in a receiving zone arranged on a support part supporting a wing. This footwear is closed on the back so as to maintain the heel and includes side flaps which, in the folded position, envelop the instep and toes. Moreover, fastening straps are provided on the support part and make it possible to adjust the tightening of the flaps at the level of the instep. These straps, however, achieve a tightening in an area of the foot that differs according to the size of the user, thus ensuring the maintenance of the foot in good conditions.

Il est également proposé par le document EP-0.572.853 , selon un mode de réalisation, une palme comprenant une partie chaussante encliquetable dans une zone de réception agencée sur une partie d'appui supportant une voilure. La partie chaussante comporte une partie chaussante basse s'encliquetant dans ladite zone de réception, un chausson notamment en néoprène qui enferme le pied, et une partie chaussante haute permettant de couvrir le cou-de-pied et les orteils enfermés dans le chausson. En outre, des sangles assujetties à la partie chaussante basse permettent de régler le serrage de la partie chaussante haute autour du cou-de-pied.It is also proposed by the document EP-0572853 , according to one embodiment, a fin comprising a snap fitting portion in a receiving zone arranged on a support portion supporting a wing. The footwear portion comprises a lower footwear snapping into said receiving area, a slipper including neoprene that encloses the foot, and a high footwear to cover the instep and toes enclosed in the liner. In addition, straps secured to the lower foot part to adjust the tightening of the upper footwear around the instep.

Il en résulte, dans ce cas, des inconvénients similaires à ceux précités, la sangle réalisant un serrage dans une zone du pied qui diffère selon la pointure de l'utilisateur. Le maintien du pied par la sangle de fixation n'est donc pas assuré dans de bonnes conditions.This results, in this case, disadvantages similar to those mentioned above, the strap making a tightening in an area of the foot that differs according to the size of the user. The support of the foot by the fastening strap is therefore not assured in good conditions.

Il est également proposé par le document EP-0.682.545 une palme équipée d'une partie chaussante comportant une partie chaussante haute indépendante d'une partie chaussante basse. La partie chaussante basse est disposée dans une zone de réception agencée sur une partie d'appui supportant une voilure. Cette partie chaussante basse est ouverte sur l'arrière. La partie chaussante haute se positionne sur le cou-de-pied, une sangle de fixation permettant de régler le serrage de la partie chaussante autour du cou-de-pied. La partie chaussante haute et la partie chaussante basse forment, une fois la sangle de fixation mise en place, un demi-chausson ouvert sur l'arrière. En outre, la partie chaussante comprend une bande élastique arrière enserrant l'arrière du pied disposé dans ledit demi-chausson ainsi formé.It is also proposed by the document EP-0682545 a fin equipped with a footwear part comprising an upper footwear independent of a footwear part. The footwear part is arranged in a receiving zone arranged on a support part supporting a wing. This footwear part is low on the back. The upper footwear is positioned on the instep, a fastening strap to adjust the tightening of the footwear around the instep. The upper foot part and the lower foot part form, once the fastening strap is in place, an open half-boot on the back. In addition, the footwear comprises a rear elastic band enclosing the back of the foot disposed in said half-boot so formed.

Dans ce cas, le maintien du pied n'est également pas assuré dans de bonnes conditions dans la mesure où la partie chaussante et la sangle de fixation réalisent un serrage dans une zone du pied qui diffère selon la pointure de l'utilisateur, une fois que la partie arrière du pied est convenablement calée, c'est-à-dire en appui, vis-à-vis de la bande élastique assurant le maintien du pied dans le demi-chausson.In this case, the support of the foot is also not ensured in good conditions insofar as the footwear and the fastening strap make a tightening in an area of the foot that differs according to the size of the user, once that the rear part of the foot is properly wedged, that is to say, in support, vis-à-vis the elastic band ensuring the maintenance of the foot in the half-slipper.

Le premier but de la présente invention est de proposer une palme qui est adaptable pour des pieds de pointures différentes, tout en palliant l'inconvénient précité.The first object of the present invention is to provide a palm that is adaptable for feet of different sizes, while overcoming the aforementioned drawback.

Le second objet de la présente invention est de proposer une palme qui non seulement est adaptable en fonction de la longueur du pied mais également en fonction de la configuration du cou-de-pied.The second object of the present invention is to provide a palm that is not only adaptable depending on the length of the foot but also depending on the configuration of the instep.

Il s'agit d'une palme qui comporte une partie chaussante et une partie d'appui, laquelle partie d'appui intègre une voilure et une zone de réception de la partie chaussante.It is a palm that includes a footwear part and a support part, which support part incorporates a wing and a receiving zone of the footwear part.

De manière caractéristique, la partie chaussante comporte une partie chaussante basse assujettie à la partie d'appui au niveau de la zone de réception de la partie d'appui et au moins une partie chaussante haute, indépendante de la partie chaussante basse. De plus, ladite palme comprend des moyens réglables de liaison aptes à assurer la liaison de la partie chaussante haute et de la partie d'appui, selon au moins deux positions longitudinales de réglage de chaque moyen de liaison par rapport à la partie d'appui, permettant un serrage desdites parties chaussantes haute et basse autour du pied de l'utilisateur, serrage qui est adaptable en fonction de la pointure dudit pied.Typically, the footwear portion comprises a footwear portion secured to the support portion at the receiving zone of the support portion and at least a high footing portion, independent of the footwear portion. In addition, said palm comprises adjustable connection means capable of ensuring the connection of the upper and the lower part of the support part, in at least two longitudinal positions of adjustment of each connecting means relative to the bearing portion , allowing a clamping said upper and lower footwear around the foot of the user, which is adaptable according to the size of said foot.

Ainsi, selon la disposition particulière de la présente invention, il suffit à l'utilisateur, en fonction de la pointure de son pied, de sélectionner la position longitudinale de réglage qui lui convient en sorte de déplacer la partie chaussante haute en relation avec les moyens de réglage de liaison et d'effectuer le serrage des parties chaussantes haute et basse autour de son pied.Thus, according to the particular arrangement of the present invention, it is sufficient for the user, depending on the size of his foot, to select the longitudinal adjustment position that suits him so as to move the upper footwear in relation to the means adjusting the binding and tightening the upper and lower footwear around his foot.

Certes on connaît par les documents EP.0.682.545 et EP-0.572.853 ,une palme équipée d'une partie chaussante haute indépendante de la partie chaussante basse qui est au niveau de la zone de réception de la partie d'appui. Cependant dans ces documents, les moyens de liaison permettant le serrage desdites parties chaussantes sont fixes et aucune indication n'est donnée concernant l'adaptation de ladite palme en fonction de la pointure du pied.Certainly we know from the documents EP.0.682.545 and EP-0572853 , a fin equipped with a high footwear independent of the footwear portion which is at the receiving zone of the support portion. However in these documents, the connecting means for clamping said footwear are fixed and no indication is given regarding the adaptation of said palm according to the size of the foot.

Selon une variante de réalisation, les moyens de liaison de la palme de la présente invention comportent :

  1. a) d'une part au moins un jeu d'au moins deux couples de moyens d'accrochage, les deux couples étant distants l'un de l'autre, et chaque couple étant constitué de deux moyens d'accrochage équipant respectivement l'un et dans l'autre des deux côtés de la partie d'appui à proximité de la zone de réception et
  2. b) d'autre part, pour chaque jeu, un élément de serrage qui est apte à coopérer avec les deux moyens d'accrochage d'un même couple.
According to an alternative embodiment, the binding means of the fin of the present invention comprise:
  1. a) at least one set of at least two pairs of means the two pairs being spaced apart from one another, and each pair being constituted by two attachment means respectively equipping one and the other of the two sides of the support part in the vicinity of the reception area and
  2. b) on the other hand, for each set, a clamping element which is adapted to cooperate with the two coupling means of the same pair.

La position de chaque couple de moyens d'accrochage détermine une position longitudinale de réglage et la distance, prise dans la direction longitudinale de la palme, entre les deux couples de moyens d'accrochage détermine l'attitude unitaire d'adaptation de la palme aux variations de pointure.The position of each pair of attachment means determines a longitudinal adjustment position and the distance, taken in the longitudinal direction of the palm, between the two pairs of attachment means determines the unitary attitude of adaptation of the palm to variations of size.

Dans un certain type de palme, la voilure n'est pas dans le prolongement de la zone de réception de la partie chaussante comme c'est le cas dans les documents US.5.259.798 , US-2005/221698 , EP-0.572.853 , et EP-0.682.545 ; elle se trouve dans un plan qui est angulairement incliné par rapport à la direction générale de la zone de réception de la partie chaussante. Pour ce faire la voilure est prolongée par deux bras latéraux qui se terminent vers l'arrière de la zone de réception de la partie chaussante. Dans ce cas, de préférence selon la présente invention, les couples de moyens d'accrochage d'un premier jeu équipant les deux dits bras latéraux.In a certain type of fin, the wing is not an extension of the reception area of the footwear part as is the case in the documents US.5.259.798 , US 2005/221698 , EP-0572853 , and EP-0682545 ; it is in a plane that is angularly inclined relative to the general direction of the receiving zone of the footwear part. To do this the wing is extended by two lateral arms which end towards the rear of the receiving zone of the footwear part. In this case, preferably according to the present invention, the pairs of attachment means of a first game equipping the two said side arms.

Selon un mode préféré de réalisation, la partie d'appui comporte, vers l'avant de la zone de réception, deux rebords latéraux qui sont équipés des couples de moyens d'accrochage d'un second jeu. Ainsi, dans ce mode de réalisation, le serrage des parties chaussantes haute et basse autour du pied de l'utilisateur est réalisé en deux endroits distincts grâce aux deux jeux de couples de moyens d'accrochage. Généralement le premier jeu permet le serrage vers l'arrière du cou-de-pied tandis que le second jeu permet le serrage vers l'avant du cou-de-pied à proximité des orteils. Cette disposition assure un maintien particulièrement efficace du pied.According to a preferred embodiment, the bearing portion comprises, towards the front of the receiving zone, two lateral flanges which are equipped with coupling means couples of a second set. Thus, in this embodiment , clamping of the upper and lower foot parts around the foot of the user is made in two different places thanks to the two sets of couples of attachment means. Generally the first set allows the backward clamping of the instep while the second set allows the forward clamping of the instep near the toes. This arrangement ensures a particularly effective maintenance of the foot.

Avantageusement, dans les modes de réalisation précités, il est prévu dans les bras latéraux et dans les rebords latéraux de la partie d'appui trois jeux de couples de moyens d'accrochage, ce qui correspond à trois positions longitudinales de réglage.Advantageously, in the aforementioned embodiments, it is provided in the lateral arms and in the lateral flanges of the support part three. sets of pairs of attachment means, which corresponds to three longitudinal adjustment positions.

Dans une variante de réalisation, la palme de la présente invention comporte deux parties chaussantes hautes, l'une antérieure et l'autre postérieure, et pour chaque partie chaussante haute, des moyens réglables de liaison. En particulier dans le mode de réalisation dans lequel la partie d'appui comporte deux bras latéraux et deux rebords latéraux, comme indiqué ci-dessus, les moyens réglables de liaison pour la partie chaussante haute postérieure comportent le premier jeu de couples de moyens d'accrochage équipant les bras latéraux et les moyens réglables de liaison pour la partie chaussante haute antérieure comportent le second jeu de couples de moyens d'accrochage équipant les rebords latéraux.In an alternative embodiment, the fin of the present invention comprises two upper foot parts, one anterior and the other posterior, and for each upper footwear, adjustable connecting means. In particular in the embodiment in which the bearing portion comprises two lateral arms and two lateral flanges, as indicated above, the adjustable connecting means for the upper back footwear portion comprise the first set of pairs of means of attachment. hooking equipping the lateral arms and the adjustable connecting means for the front upper footwear portion comprise the second set of pairs of hooking means equipping the lateral flanges.

De préférence, l'élément de serrage est une sangle qui comporte des moyens permettant sa fermeture sur elle-même et les moyens d'accrochage consistent en une fente formée dans la partie d'appui et permettant le passage de ladite sangle.Preferably, the clamping element is a strap which comprises means for closing it on itself and the attachment means consist of a slot formed in the support part and allowing the passage of said strap.

De préférence dans ce cas, pour chaque sangle, les moyens de liaison comprennent également un passant de positionnement qui est monté sur la partie chaussante haute correspondant à ladite sangle. La sangle en question passe dans le passant avec un jeu réduit de sorte que le passant assure effectivement un positionnement précis de la sangle sur ladite partie chaussante haute.Preferably in this case, for each strap, the connecting means also comprise a positioning loop which is mounted on the upper fitting part corresponding to said strap. The strap in question passes in the loop with a reduced clearance so that the passer actually ensures precise positioning of the strap on said upper footwear.

Les moyens permettant la fermeture sur elle-même de la sangle sont notamment des éléments auto agrippants du type crochets et boucles, par exemple ceux qui sont bien connus sous la dénomination Velcro® .The means allowing the closure on itself of the strap are in particular self-gripping elements of the hook and loop type, for example those which are well known under the name Velcro ® .

Dans le mode de réalisation d'une palme de natation dont la partie d'appui comporte deux bras, de préférence les fentes sur chaque bras sont parallèles entre elles, décalées l'une de l'autre d'une distance donnée et sensiblement inclinées vers l'avant. Le décalage détermine la distance entre les différentes positions de réglage. L'inclinaison vers l'avant correspond sensiblement à l'inclinaison du dessus du cou-de-pied de manière à obtenir une bonne application de la sangle sur la partie chaussante haute.In the embodiment of a swimming fin whose supporting portion comprises two arms, preferably the slots on each arm are parallel to each other, offset from one another by a given distance and substantially inclined towards forward. The offset determines the distance between the different adjustment positions. The inclination forwards substantially corresponds to the inclination of the top of the instep so as to obtain a good application of the strap on the upper footwear.

La présente invention sera mieux comprise à la lecture de la description qui va être faite ci-après d'un exemple préféré de réalisation d'une palme de natation équipée de moyens de réglage permettant son adaptation en fonction de la pointure du pied de l'utilisateur, illustré par le dessin annexé dans lequel :

  • la figure 1 est une représentation schématique de côté de ladite palme dans une première position de réglage, correspondant à une pointure de petite taille ;
  • la figure 2 est une représentation schématique de la palme de la figure 1 dans une deuxième position de réglage correspondant à une pointure de taille moyenne et
  • la figure 3 est une représentation schématique de la palme de la figure 1 dans une troisième position de réglage correspondant à une pointure de grande taille.
The present invention will be better understood on reading the following description of a preferred embodiment of a swimming fin equipped with adjustment means for its adaptation according to the size of the foot of the user, illustrated by the accompanying drawing in which:
  • the figure 1 is a schematic side view of said palm in a first setting position, corresponding to a small size;
  • the figure 2 is a schematic representation of the palm of the figure 1 in a second adjustment position corresponding to a size of average size and
  • the figure 3 is a schematic representation of the palm of the figure 1 in a third adjustment position corresponding to a large size.

La palme de natation 1 comporte une partie chaussante 2 et une partie dite d'appui 3 qui comprend une voilure 4 et une zone de réception 5 de la partie chaussante 2.The swimming fin 1 comprises a footwear portion 2 and a so-called support portion 3 which comprises a wing 4 and a receiving zone 5 of the footwear portion 2.

Dans le mode de réalisation qui est décrit et illustré ci-après, à titre d'exemple non limitatif, la voilure n'est pas dans le prolongement de la zone de réception 5 ; elle est décalée angulairement, étant inclinée vers le bas par rapport au plan que forme la direction générale de ladite zone de réception 5. Pour ce faire, la partie d'appui 3 comporte deux bras latéraux 11 qui prolongent la voilure 4 latéralement jusque vers l'arrière 5a de la zone de réception 5.In the embodiment which is described and illustrated below, by way of non-limiting example, the wing is not in the extension of the receiving zone 5; it is angularly offset, being inclined downwards with respect to the plane formed by the general direction of said receiving zone 5. To this end, the bearing portion 3 comprises two lateral arms 11 which extend the wing 4 laterally to rear 5a of the reception zone 5.

De plus la partie d'appui 3 comporte, vers l'avant 5b de la zone de réception, deux rebords latéraux 15 qui sont eux-mêmes reliés à l'arrière de la voilure 4 par deux bras latéraux auxiliaires 16.In addition, the bearing portion 3 comprises, towards the front 5b of the receiving zone, two lateral flanges 15 which are themselves connected to the rear of the wing 4 by two auxiliary lateral arms 16.

Selon la présente invention, la partie chaussante 2 de la palme est constituée d'une partie basse 6 et d'une partie haute 7 qui sont indépendantes l'une de l'autre ; c'est la partie basse 6 qui est appliquée sur la partie d'appui 3 selon toute la zone de réception 5, étant fixée ou fixable à celle-ci ou encore intégrée à celle-ci par surmoulage, en particulier lorsque la partie chaussante 2 est formée à partir d'un matériau du type élastomère, différent de celui dans lequel est formée la partie d'appui 3.According to the present invention, the footwear part 2 of the palm consists of a lower part 6 and an upper part 7 which are independent of one another; it is the lower part 6 which is applied to the support part 3 along the entire receiving zone 5, being fixed or fixable thereto or integrated therewith by overmolding, in particular when the footwear part 2 is formed from a material of the elastomer type, different from that in which the support part 3 is formed.

Comme illustré sur les figures, l'arrière 6a de la partie chaussante basse 6 a une configuration en forme de coque pour accueillir l'arrière du pied, notamment le talon.As illustrated in the figures, the rear 6a of the lower footwear part 6 has a configuration in the form of a shell to accommodate the rear of the foot, in particular the heel.

La partie chaussante haute 7 est destinée à envelopper partiellement le dessus du pied, notamment le cou-de-pied comme cela peut apparaître sur la figure 1. La configuration géométrique de la partie chaussante haute 7 est sensiblement complémentaire de celle de la partie chaussante basse 6. Dans le cas d'un réglage longitudinal correspondant à une pointure de petite taille, les bords arrière 7a et inférieur 7b de la partie chaussante haute 7 sont à proximité immédiate de la partie chaussante basse 6 et des bords 6b et 6c correspondants.The uppermost portion 7 is intended to partially wrap the top of the foot, especially the instep as may appear on the figure 1 . The geometrical configuration of the upper footwear portion 7 is substantially complementary to that of the lower footwear portion 6. In the case of a longitudinal adjustment corresponding to a small size, the rear edges 7a and 7b of the lower footwear 7 are in close proximity to the lower footwear portion 6 and corresponding edges 6b and 6c.

Sur la figure 1, qui correspond à un tel réglage, on voit clairement qu'entre les deux parties chaussantes basse 6 et haute 7, il n'existe qu'un écartement très faible, lesdites parties enveloppant parfaitement le pied à l'exception des orteils.On the figure 1 , which corresponds to such an adjustment, it is clearly seen that between the two lower footwear 6 and high 7, there is only a very small spacing, said parts perfectly enveloping the foot except the toes.

Selon la présente invention, la palme 1 comprend des moyens réglables de liaison 8 aptes à assurer la liaison de la partie chaussante haute 7 et de la partie d'appui 3, selon au moins deux positions longitudinales de réglage et aptes à permettre un serrage desdites parties chaussantes haute 7 et basse 6 autour du pied 17 de l'utilisateur, ledit serrage étant adaptable en fonction de la pointure du pied.According to the present invention, the fin 1 comprises adjustable connecting means 8 adapted to ensure the connection of the upper footwear portion 7 and the support portion 3, in at least two longitudinal adjustment positions and able to allow clamping of said upper 7 and lower 6 footwear parts around the foot 17 of the user, said clamping being adaptable depending on the size of the foot.

Dans l'exemple illustré, les moyens réglables de liaison 8 comportent deux jeux de trois couples de moyens d'accrochage, formés respectivement dans les deux bras latéraux 11 pour le premier jeu et dans les deux rebords latéraux 15 pour le second jeu, à proximité de la zone de réception 5 ; en l'occurrence, chaque moyen d'accrochage est une fente, référencée 10 s'agissant des fentes pratiquées dans les deux bras latéraux 11 et référencée 14 pour celles pratiquées dans les deux rebords latéraux 15 ; il y a donc trois fentes 10 dans le bras latéral gauche et, avec la même disposition, trois fentes pratiquées dans le bras latéral droit, non visible sur les figures, constituant ainsi trois couples de fentes 10. Chaque couple détermine une position longitudinale de réglage. Le couple de fentes 10a le plus à droite sur la figure 1, qui est le plus proche de la coque 6a, correspond au réglage pour un pied de plus petite taille. A l'opposé, le couple de fentes 10c le plus à gauche de la figure 1, c'est-à-dire le plus éloigné de la coque 6a, correspond au réglage pour un pied de plus grande taille ; il en est de même pour les trois couples de fentes 14 formés dans le rebord latéral gauche 15, visible sur la figure 1 et dans le rebord latéral droit non visible.In the example illustrated, the adjustable connecting means 8 comprise two sets of three pairs of attachment means, respectively formed in the two lateral arms 11 for the first set and in the two lateral flanges 15 for the second set, close to the reception zone 5; in this case, each attachment means is a slot, referenced 10 with respect to the slots in the two lateral arms 11 and referenced 14 for those made in the two lateral flanges 15; there are therefore three slots 10 in the left lateral arm and, with the same arrangement, three slots made in the right lateral arm, not visible in the figures, thus constituting three pairs of slots 10. Each pair determines a longitudinal adjustment position. The couple of slots 10a the rightmost on the figure 1 , which is the closest to the hull 6a, corresponds to the setting for a smaller foot. In contrast, the couple of slots 10c the furthest left of the figure 1 , that is to say the farthest from the hull 6a, corresponds to the setting for a foot of larger size; it is the same for the three pairs of slots 14 formed in the left lateral rim 15, visible on the figure 1 and in the right side edge not visible.

Les moyens réglables de liaison 8 comportent également, pour chaque jeu, un élément de serrage qui, en l'occurrence, est une sangle, respectivement, 9 pour le premier jeu et 13 pour le second jeu, présentant des moyens de fermeture sur elle-même qui consistent en des éléments d'accrochage du type à crochets et boucles 12. La largeur et l'épaisseur de la sangle 9, 13 sont déterminées pour permettre son passage à travers chacune des fentes 10, 14.The adjustable connecting means 8 also comprise, for each set, a clamping element which, in this case, is a strap, respectively, 9 for the first set and 13 for the second set, having closure means on it. The width and thickness of the strap 9, 13 are determined to allow it to pass through each of the slots 10, 14.

Avant son utilisation, les sangles 9 et 13 ne sont pas refermées sur elles-mêmes, laissant dégagée la partie chaussante haute 7 ; l'utilisateur peut ainsi placer facilement son pied sur la partie chaussante basse 6 et venir caler son talon vers l'intérieur de la coque arrière 6a ; considérant que cet utilisateur a une pointure qui correspond à une petite taille, les sangles 9 et 13 sont passées par-dessus la partie chaussante haute 7 dans les couples correspondant aux fentes 10a et 14a, les plus à droite. Pour obtenir un serrage adéquat, il suffit à l'utilisateur de se saisir de la première sangle 9, de la mettre en tension pour obtenir un serrage de la partie chaussante haute. 7 contre l'arrière du cou-de-pied et de refermer cette sangle sur elle-même en appliquant les éléments auto-agrippants 12 les uns contre les autres.Before its use, the straps 9 and 13 are not closed on themselves, leaving unobstructed upper footwear 7; the user can thus easily place his foot on the footwear part 6 and come wedge his heel inwardly of the rear shell 6a; considering that this user has a size which corresponds to a small size, the straps 9 and 13 are passed over the upper footwear part 7 in the pairs corresponding to the slots 10a and 14a, the more right. To obtain an adequate tightening, it is sufficient for the user to seize the first strap 9, to put it in tension to obtain a tightening of the upper footwear. 7 against the back of the instep and close the strap on itself by applying the self-gripping elements 12 against each other.

Chaque fente 10 est légèrement inclinée vers l'avant par rapport à la direction générale de la zone de réception 5, correspondant à la direction générale de la plante du pied 17. Cette inclinaison correspond à l'inclinaison moyenne du cou-de-pied de l'utilisateur de manière à permettre une bonne application de la sangle sur la partie chaussante haute, évitant ainsi le glissement possible de la sangle pendant l'utilisation.Each slot 10 is slightly inclined forwards with respect to the general direction of the receiving zone 5, corresponding to the general direction of the sole of the foot 17. This inclination corresponds to the average inclination of the instep of the user so as to allow a good application of the strap on the upper footwear, thus avoiding the possible slippage of the strap during use.

Il en est de même, dans une moindre mesure, en ce qui concerne les fentes 14 pour la seconde sangle 13 qui vient en appui sur l'avant de la partie chaussante haute 7, en arrière des orteils.It is the same, to a lesser extent, with respect to the slots 14 for the second strap 13 which bears on the front of the upper footwear part 7, behind the toes.

Si l'utilisateur a une pointure de pied qui correspond à une taille plus importante, il peut, grâce à l'invention, modifier le réglage longitudinal des moyens de liaison. Pour ce faire, il déplace les sangles 9 et 13 d'un couple de fentes 10 et 14 à l'autre. La figure 2 illustre le réglage correspondant pour une pointure de taille moyenne, les sangles 9 et 13 étant passées à travers les couples de fentes intermédiaires 10b et 14b.If the user has a foot size which corresponds to a larger size, he can, thanks to the invention, modify the longitudinal adjustment of the connecting means. To do this, he moves the straps 9 and 13 of a pair of slots 10 and 14 to each other. The figure 2 illustrates the corresponding setting for a size of medium size, the straps 9 and 13 being passed through the pairs of intermediate slots 10b and 14b.

On constate que, par rapport à la figure 1, la partie chaussante haute 7 s'est légèrement décalée vers la gauche et vers le haut par rapport à la partie chaussante basse 6 du fait de l'augmentation relative du volume du pied 17.It can be seen that compared to the figure 1 the upper footwear portion 7 has shifted slightly to the left and upwards relative to the lower footwear portion 6 due to the relative increase in the volume of the foot 17.

La figure 3 illustre le réglage de la palme 1 pour une pointure correspondant à une grande taille ; les sangles 9 et 13 sont passées dans les couples de fentes 10c et 14c les plus éloignées de la coque arrière 6a ; le décalage entre la partie chaussante haute 7 et la partie chaussante basse 6 est encore plus important aussi bien longitudinalement qu'en hauteur.The figure 3 illustrates the setting of palm 1 for a size corresponding to a large size; the straps 9 and 13 are passed in the pairs of slots 10c and 14c farthest from the rear shell 6a; the offset between the upper footwear part 7 and the lower footwear part 6 is even more important both longitudinally and in height.

Dans cette position, l'extrémité antérieure du pied 17a est légèrement en retrait par rapport à l'extrémité avant 6b de la partie chaussante basse 6. Du fait de la structure de la palme 1 avec la voilure 4 décalée angulairement par rapport à la partie d'appui 3 de la partie chaussante 2, il n'y a aucune incidence sur le fonctionnement de la palme lors du battement du pied, contrairement à ce qui pourrait se passer dans le cas d'une palme dans laquelle la voilure se trouve dans le prolongement de la zone de réception d'appui de la partie chaussante, tel que décrit dans le document US-5.259.798 . En effet, dans ce cas, si la palme était utilisée pour une pointure plus importante, les orteils viendraient s'appliquer sur la voilure proprement dite de la palme, ce qui pourrait perturber le bon fonctionnement de celle-ci.In this position, the anterior end of the foot 17a is slightly recessed with respect to the front end 6b of the lower footwear portion 6. Because of the structure of the fin 1 with the wing 4 angularly offset from the portion 3 of the footwear part 2, there is no impact on the operation of the palm during the flapping of the foot, unlike what could happen in the case of a palm in which the blade is in the extension of the support receiving zone of the footwear part, as described in the document US 5259798 . Indeed, in this case, if the palm was used for a larger size, the toes would apply on the wing itself of the palm, which could disrupt the proper functioning thereof.

La présente invention n'est pas limitée au mode de réalisation qui a été décrit ci-dessus à titre d'exemple non exclusif. En particulier, pour maintenir dans une bonne position chacune des sangles 9, 13 sur la partie chaussante haute 7, il peut être prévu des passants, non représentés, fixés sur le dessus de ladite partie chaussante 7, empêchant le glissement des sangles 9 et 13 lors de l'utilisation de la palme 1.The present invention is not limited to the embodiment which has been described above as a non-exclusive example. In particular, to maintain in a good position each of the straps 9, 13 on the upper footwear portion 7, there may be provided loops, not shown, fixed on the top of said foot portion 7, preventing the slippage of the straps 9 and 13 when using palm 1.

De plus, la partie chaussante 2 peut comporter non pas une seule partie chaussante haute comme décrite ci-dessus mais une partie chaussante haute antérieure et une partie chaussante postérieure, indépendantes l'une de l'autre. Dans ce cas, il y a obligatoirement pour chaque partie chaussante haute, des moyens réglables de liaison. Dans l'exemple décrit ci-dessus et illustré, les moyens réglables de liaison pour la partie chaussante haute postérieure comporteraient le premier jeu de couples de moyens d'accrochage formés dans les bras latéraux, tandis que les moyens réglables de liaison pour la partie chaussante haute antérieure comporteraient le second jeu de couples de moyens d'accrochage formés dans les rebords latéraux 15.In addition, the footwear portion 2 may comprise not only a high footwear portion as described above but an upper front footwear portion and a back foot portion, independent of one another. In this case, there is obligatorily for each upper footwear, adjustable means of connection. In the example described above and illustrated, the adjustable connecting means for the upper back footwear portion comprise the first set of couples of attachment means formed in the side arms, while the adjustable connecting means for the footwear part. upper front would comprise the second set of pairs of attachment means formed in the lateral flanges 15.

Ce mode particulier de réalisation, qui dissocie la partie chaussante haute en deux pièces distinctes, permet un réglage plus fin du serrage de la partie chaussante sur le pied, permettant une meilleure adaptation en fonction de la conformation spécifique du pied, notamment du cou-de-pied, de l'utilisateur.This particular embodiment, which dissociates the upper footwear into two separate parts, allows a finer adjustment of the tightening of the footwear part on the foot, allowing a better adaptation according to the specific conformation of the foot, including the neck-de -foot, of the user.

L'élément de serrage étant une sangle comportant des moyens permettant sa fermeture sur elle-même, les moyens d'accrochage ne sont pas obligatoirement une fente qui est pratiquée dans les deux côtés de la partie d'appui. Il peut s'agir d'une fente se présentant sous la forme d'une lumière dans une boucle qui est elle-même fixée sur le côté de la partie d'appui à proximité de la zone de réception. Dans ce cas, il n'y a pas de risque d'altération des propriétés mécaniques de la partie d'appui, altération qui serait due à la présence des fentes, notamment dans les bras latéraux de la partie d'appui.The clamping element being a strap having means for closing it on itself, the attachment means are not necessarily a slot which is formed in both sides of the support part. It may be a slot in the form of a light in a loop which is itself fixed on the side of the support part near the receiving area. In this case, he there is no risk of alteration of the mechanical properties of the support part, alteration which would be due to the presence of the slots, in particular in the lateral arms of the support part.

Enfin, d'autres types de moyens d'accrochage peuvent être envisagés pour autant qu'ils soient aptes à coopérer avec un élément de serrage adapté. Il pourrait par exemple s'agir de plots venant en saillie sur les côtés de la partie d'appui à proximité de la zone de réception ; dans ce cas, l'élément de serrage pourrait être une sangle élastique dont chaque extrémité serait pourvue d'une ouverture permettant sa fixation sur l'un des plots.Finally, other types of attachment means may be envisaged provided that they are able to cooperate with a suitable clamping element. It could for example be pads protruding from the sides of the support part near the reception area; in this case, the clamping element could be an elastic strap each end of which would be provided with an opening allowing its attachment to one of the pads.
