Description

Engin nautique à propulsion par la force humaine.Nautical craft propelled by human force.
L'invention concerne un engin nautique à propulsion par la force humaine.The invention relates to a nautical craft powered by human force.
L'inventeur a imaginé un nouvel engin destiné aux sports et/ou aux jeux nautiques.The inventor has devised a new machine for sports and / or water games.
On connaît bien sûr les bouées qui n'offrent aucune possibilité aisée d'avancer dans l'eau.Of course we know buoys that offer no easy way to advance in the water.
On connaît aussi des engins plus sophistiqués à pédaliers qui sont de véritables embarcations. C'est ainsi par exemple qu'il existe de nombreux appareils décrits notamment dans les documents FR-2 027 328-A, GB-180 227-A, FR-2 609 681 -A, GB-2 272 412- A, ou encore EP-O 287 526-A.We also know more sophisticated gear with pedals that are real boats. For example, there are numerous devices described in particular in the documents FR-2,027,328-A, GB-180,227-A, FR-2,609,681 -A, GB-2,272,412-A, or still EP-0 287 526-A.
Tous les dispositifs décrits dans ces documents nécessitent, outre des flotteurs, une selle ou un siège pour s'asseoir, un guidon ou des poignées pour diriger l'engin et un moyen de propulsion généralement sous forme d'un pédalier avec une hélice, ou encore sous forme de palmes pour le FR-2 609 681 -A.All devices described in these documents require, in addition to floats, a saddle or seat to sit, a handlebar or handles to steer the machine and a propulsion means generally in the form of a pedal with a propeller, or still in the form of flippers for FR-2 609 681-A.
L'inventeur a eu le mérite d'imaginer un engin très simple et donc peu onéreux et facile d'utilisation contrairement à tout l'art connu précité.The inventor had the merit of imagining a very simple machine and therefore inexpensive and easy to use unlike all the aforementioned art.
L'engin nautique conçu par l'inventeur, à propulsion par la force humaine et qui est pourvu d'au moins un flotteur, est notamment remarquable en ce qu'il présente un cadre ouvert formant au moins un U, ou une lyre, dont les extrémités des branches sont pourvues chacune d'au moins un flotteur oblong disposé transversalement et fixement par rapport audit cadre en dépassant de part et d'autre de celui-ci et permettant à l'utilisateur d'y appuyer ses mains, le fond de chaque U du cadre étant destiné à servir de soutien audit utilisateur assis à califourchon sur ledit cadre, de telle sorte que l'utilisateur peut librement remuer ses jambes dans l'eau et ainsi se mouvoir avec ledit engin.The nautical craft designed by the inventor, propelled by human force and which is provided with at least one float, is notably remarkable in that it has an open frame forming at least one U, or a lyre, of which the ends of the branches are each provided with at least one oblong float disposed transversely and fixedly relative to said frame protruding on either side of it and allowing the user to press his hands, the bottom of each U of the frame being intended to support said user sitting astride said frame, so that the user can freely move his legs in the water and thus move with said machine.
Un tel engin est particulièrement ludique et/ou adapté à la pratique du sport nautique tandis qu'il ne nécessite contrairement à l'art connu, d'aucune selle, d'aucun guidon et dans sa version de base d'aucun moyen auxiliaire de propulsion.Such a machine is particularly playful and / or adapted to the practice of water sports while it does not require the known art, no saddle, no handlebars and in its basic version of any auxiliary means of propulsion.
Selon des modes de réalisation, le cadre comporte un élément rigide ou semi-rigide qui est en partie en forme de gouttière pour loger un élément gonflable, ou bien qui est fixé dans un élément gonflable, ou encore, le cadre comporte une âme rigide ou semi-rigide enrobé au moins partiellement d'une matière plus souple. Selon un mode de réalisation, le ou les flotteurs transversaux sont des éléments gonflables éventuellement d'une seule pièce avec le cadre et par exemple dans ce cas, des bras supports gonflables sont prévus entre les flotteurs transversaux et le cadre. Toutefois, l'inventeur a également prévu un mode de réalisation dans lequel les flotteurs transversaux sont pourvus chacun d'un élément rigide ou semi-rigide muni ou non d'un mécanisme de pliage au niveau de sa jonction avec le cadre.According to embodiments, the frame comprises a rigid or semi-rigid element which is partly in the form of a gutter for housing an inflatable element, or which is fixed in an inflatable element, or the frame comprises a rigid core or semi-rigid at least partially coated with a softer material. According to one embodiment, the transverse float or floats are possibly inflatable elements in one piece with the frame and for example in this case, inflatable support arms are provided between the transverse floats and the frame. However, the inventor has also provided an embodiment in which the transverse floats are each provided with a rigid or semi-rigid element with or without a folding mechanism at its junction with the frame.
Par exemple, les extrémités des branches de chaque U du cadre sont pourvues chacune d'une tête destinée à la fixation du ou des flotteurs transversaux, tandis qu'avec un cadre muni d'une âme rigide ou semi-rigide, celle-ci s'étend jusque dans les têtes d'extrémité et présente dans chacune desdites têtes un logement destiné à être traversé par l'élément rigide ou semi-rigide correspondant des flotteurs en vue de leur fixation, ledit élément se présentant sous la forme d'une âme rigide ou semi-rigide. De préférence dans ce dernier cas, les sections, d'une part, de l'âme des flotteurs et, d'autre part, des logements de l'âme du cadre, sont polygonales afin d'assurer une fixation en rotation de l'âme des flotteurs dans les têtes du cadre.For example, the ends of the branches of each U of the frame are each provided with a head for fixing the transverse float or floats, while with a frame provided with a rigid or semi-rigid core, the latter extends into the end heads and has in each of said heads a housing to be traversed by the corresponding rigid or semi-rigid member floats for attachment, said element being in the form of a soul rigid or semi-rigid. Preferably in the latter case, the sections, on the one hand, of the core of the floats and, on the other hand, the housing of the core of the frame, are polygonal to ensure a rotational fixation of the soul of the floats in the heads of the frame.
Avantageusement, chaque tête du cadre présente une partie articulée verrouillable constituant un côté du logement dont la tête est munie, de manière à permettre l'introduction et la fixation aisée de l'âme des flotteurs.Advantageously, each head of the frame has a lockable articulated portion constituting a side of the housing whose head is provided, so as to allow the introduction and easy attachment of the soul of the floats.
Toutefois, selon une variante, chaque tête du cadre présente un logement ouvert dans lequel peut être introduite et encliquetée l'âme des flotteurs.However, according to one variant, each head of the frame has an open housing into which the float core can be inserted and snapped.
Selon un mode de réalisation, le ou les flotteurs transversaux comportent chacun deux éléments gonflables ou non, ayant une âme rigide ou semi-rigide commune et qui sont disposés bout à bout, chacun d'un côté distinct de la tête correspondante du cadre.According to one embodiment, the transverse float or floats each comprise two inflatable elements or not, having a rigid core or semi-rigid joint and which are arranged end to end, each on a separate side of the corresponding head of the frame.
Par ailleurs et selon une autre variante, même si l'invention est plutôt destinée à concevoir un engin simplifié, on peut bien sûr envisager un engin plus sophistiqué dans lequel le cadre est muni de moyens de fixation pour deux pattes dont l'une est équipée d'un pédalier pourvu de pédales solidaires en rotation d'un réa et l'autre, d'une hélice, également solidaire d'un réa, tandis que lesdits réas sont reliés entre eux, via au moins une poulie de renvoi, par une courroie d'entraînement.Moreover and according to another variant, even if the invention is rather intended to design a simplified machine, one can of course consider a more sophisticated machine in which the frame is provided with fastening means for two legs, one of which is equipped a pedal provided with pedals integral in rotation of a sheave and the other, a propeller, also integral with a sheave, while said sheaves are interconnected, via at least one sheave pulley, by a drive belt.

- les figures 20 à 23 montrent un mode de réalisation semblable à celui des figures 16 à 19 mais avec une armature interne, les figures 20, 21 et 23 correspondant aux figures respectivement 16, 17 et 19 et la figure 22 étant une vue de l'engin de face,FIGS. 20 to 23 show an embodiment similar to that of FIGS. 16 to 19 but with an internal reinforcement, FIGS. 20, 21 and 23 corresponding to FIGS. 16, 17 and 19, respectively, and FIG. 22 being a view of FIG. machine in front,
- les figures 24 à 27 montrent un mode de réalisation semblable à celui des figures 20 à 23, mais pourvu d'une armature interne pliable, les figures 24 à 27 correspondant aux figures respectivement 20 à 23.- Figures 24 to 27 show an embodiment similar to that of Figures 20 to 23, but provided with a foldable internal frame, Figures 24 to 27 corresponding to Figures 20 to 23 respectively.
Sur les figures 1 à 12, on peut donc voir selon des modes de réalisation donnés à titre d'exemple, un engin comportant principalement un cadre 1 en forme générale ici de U à fond arrondi, ou en forme de lyre, et pourvu à chacune de ses extrémités, ici recourbées vers l'extérieur, d'une tête 2, 2' fixant chacune un flotteur 3, 3' disposé transversalement par rapport au plan défini par le cadre 1.In FIGS. 1 to 12, according to embodiments given by way of example, it is therefore possible to see a machine comprising mainly a frame 1 in the general form here of U with a rounded bottom, or in the form of a lyre, and provided with each its ends, here bent outwards, of a head 2, 2 'each fixing a float 3, 3' arranged transversely to the plane defined by the frame 1.
Le cadre 1 , comme le montrent plus particulièrement les figures 2, 3 et 4, 5, est constitué par une âme 1a rigide ou semi-rigide enrobée au moins partiellement d'une matière plus souple 1 b.Frame 1, as shown more particularly in Figures 2, 3 and 4, 5, is constituted by a core 1a rigid or semi-rigid at least partially coated with a softer material 1b.
Les figures 4 et 5 montrent un mode de réalisation dans lequel la matière 1 b est essentiellement présente dans le fond du U du cadre 1.FIGS. 4 and 5 show an embodiment in which the material 1 b is essentially present in the bottom of the U of the frame 1.
Les extrémités de l'âme 1a du cadre 1 s'étendent jusque dans les têtes 2, 2' et sont pourvues dans cet exemple d'un logement 4, 4' de forme polygonale, triangulaire dans les figures 1 à 3 et 7 à 12 et rectangulaire dans les figures 4 à 6.The ends of the web 1a of the frame 1 extend into the heads 2, 2 'and are provided in this example with a housing 4, 4' of polygonal shape, triangular in Figures 1 to 3 and 7 to 12 and rectangular in Figures 4 to 6.
Les logements 4, 4' des têtes du cadre des figures 1 à 3 et 7, 8 sont constitués par des alésages triangulaires, tandis que le logement des figures 4 à 6 est constitué par une encoche rectangulaire ouverte, et chaque logement des figures 9 àThe housings 4, 4 'of the frame heads of FIGS. 1 to 3 and 7, 8 are constituted by triangular bores, whereas the housing of FIGS. 4 to 6 is constituted by an open rectangular notch, and each housing of FIGS.
12 est constitué, comme il sera expliqué ci-après, par une fourche sur laquelle vient se refermer un élément articulé.12 is formed, as will be explained below, by a fork on which is closed an articulated element.
Chacun des flotteurs 3, 3', comme le montrent plus particulièrement les figures 3 et 5, 6, est également pourvu d'une âme rigide ou semi-rigide 3a, 3'a. Par contre, l'âme 3a, 3'a de chaque flotteur est enveloppée ici de deux éléments Sb1, 3b2 ; 3'b.,, 3'b2, gonflables sur les figures 1 à 3, ou non gonflables sur les figures 4 à 6, destinés à venir de part et d'autre de la tête 2, 2' correspondante du cadre 1. Toutefois, on peut également prévoir un seul élément, gonflable ou non, par flotteur, comme on le verra ci-après, voire aussi un seul élément interrompu au niveau de la tête du cadre.Each of the floats 3, 3 ', as shown more particularly in FIGS. 3 and 5, 6, is also provided with a rigid or semi-rigid core 3a, 3'a. By cons, the soul 3a, 3'a of each float is wrapped here two elements Sb 1 , 3b 2 ; 3'b. ,, 3'b 2 , inflatable in Figures 1 to 3, or non-inflatable in Figures 4 to 6, intended to come on either side of the corresponding head 2, 2 'of the frame 1. However, it is also possible to provide a single element, inflatable or not, by float, as will be seen below, or even a single interrupted element at the frame head.
Dans les exemples représentés, sur les figures 1 à 12 on remarquera donc que les deux éléments 3b-i, 3b2 ; 3'b-i, 3'b2 de chaque flotteur présentent une âme commune 3a, 3'a qui traverse la tête correspondante 2, 2' du cadre 1. En outre, on remarquera aussi que les âmes 3a, 3'a des flotteurs et donc les éléments eux-mêmes, sont incurvés vers l'intérieur sur les figures 1 à 3, ou bien sont rectilignes, comme représenté sur les figures 4 à 6.In the examples shown, in FIGS. 1 to 12, it will therefore be noted that the two elements 3b-1, 3b 2 ; 3'bi, 3'b 2 of each float have a common core 3a, 3'a which passes through the corresponding head 2, 2 'of the frame 1. In addition, it will also be noted that the souls 3a, 3'a floats and therefore the elements themselves, are curved inwards in Figures 1 to 3, or are rectilinear, as shown in Figures 4 to 6.
Pour une bonne fixation des âmes 3a, 3'a des flotteurs, celles-ci présentent une section polygonale conjuguée de celle des logements 4, 4' de l'âme 1 a du cadre de façon à s'y introduire et d'être ainsi fixes en rotation et dans les exemples donc, triangulaire ou rectangulaire.For a good fixing of the souls 3a, 3'a floats, they have a polygonal section conjugate to that of the housing 4, 4 'of the soul 1a of the frame so as to be introduced and to be so fixed in rotation and in the examples therefore, triangular or rectangular.
On comprend que les éléments de chaque flotteur 3, 3' sont disposés de part et d'autre des têtes 2, 2' de telle sorte que lesdits éléments sont également maintenus transversalement. Les figures 7 et 8 montrent plus en détail une tête 2 du cadre 1 des figures 1 à 3 selon donc un mode de réalisation simplifié dans lequel, pour l'introduction de l'âme 3a des flotteurs dans ladite tête 2, éventuellement par l'intermédiaire d'un amortisseur 5, il suffit que les éléments gonflables Sb1, 3b2 soient entièrement dégonflés, leur gonflage s'effectuant après ladite introduction. Toutefois, afin de faciliter le montage des flotteurs, l'inventeur a imaginé une tête dont le logement est ouvert (figures 4 à 6), ou qui peut s'ouvrir et se verrouiller comme le montrent les figures 9 à 12.It is understood that the elements of each float 3, 3 'are arranged on either side of the heads 2, 2' so that said elements are also held transversely. FIGS. 7 and 8 show in more detail a head 2 of the frame 1 of FIGS. 1 to 3 according to a simplified embodiment in which, for the introduction of the core 3a, floats in said head 2, possibly by means of intermediate a damper 5, it is sufficient that the inflatable elements Sb 1 , 3b 2 are completely deflated, their inflation being effected after said introduction. However, to facilitate the mounting of the floats, the inventor has imagined a head whose housing is open (Figures 4 to 6), or which can open and lock as shown in Figures 9 to 12.
Dans le mode de réalisation des figures 4 à 6 en effet, le logement 4, 4' est rectangulaire, ou carré, et peut recevoir par encliquetage l'âme 3a, 3'a du flotteur correspondant.In the embodiment of FIGS. 4 to 6 in fact, the housing 4, 4 'is rectangular, or square, and can snap-fit the core 3a, 3'a of the corresponding float.
Dans le mode de réalisation des figures 9 à 12, la tête 2 présente une partie articulée 6 qui peut pivoter comme le montre la figure 9 et se verrouiller au moyen d'un système comportant ici un crochet 7 à levier d'un côté et un cran 8 approprié de l'autre côté. Dans ce mode de réalisation, le logement de la tête 2 est constitué par une fourche aménagée à l'extrémité de l'âme 1 a du cadre et dont la partie ouverte peut se refermer par la partie articulée 6.In the embodiment of FIGS. 9 to 12, the head 2 has an articulated portion 6 which can pivot as shown in FIG. 9 and lock by means of a system comprising here a hook 7 with a lever on one side and a notch 8 appropriate on the other side. In this embodiment, the housing of the head 2 is constituted by a fork arranged at the end of the web 1a of the frame and whose open portion can be closed by the articulated portion 6.
Les figures 13 à 15 représentent un accessoire qui peut être fixé sur l'engin précédemment décrit, ceci étant donné à titre d'exemple pour montrer qu'à partir d'un engin simple selon l'invention on peut bien sûr envisager de le rendre plus sophistiqué.FIGS. 13 to 15 represent an accessory which can be fixed on the machine previously described, this being given by way of example to show that from a simple machine according to the invention, it is of course conceivable to make it more sophisticated.
Cet accessoire comporte un berceau 9 destiné à être fixé dans la partie inférieure arrondie du cadre 1 pourvue à cet effet d'ajours de fixation 10, 10' visibles sur les figures 1 à 3 et 13. Le berceau 9 en forme de gouttière arrondie est pourvu de deux pattes 11 etThis accessory comprises a cradle 9 intended to be fixed in the rounded lower part of the frame 1 provided for this purpose of fastening openings 10, 10 'visible in FIGS. 1 to 3 and 13. The cradle 9 in the form of a rounded gutter is provided with two legs 11 and
12 dont l'une, 1 1 , est munie d'un pédalier 13 et l'autre, 12, d'une hélice 14.12 of which one, 1 1, is provided with a pedal 13 and the other, 12, a propeller 14.
Le pédalier 13 comporte comme représenté, deux pédales 15, 15' qui entraînent un réa 16.The pedal 13 comprises as shown, two pedals 15, 15 'which cause a sheave 16.
Comme le montre en outre la figure 13, le pédalier 13 est monté de manière réglable sur une partie de la patte 1 1.As further shown in Figure 13, the pedal 13 is adjustably mounted on a portion of the lug 1 January 1.
L'hélice 14 est solidaire également d'un réa 17 tandis qu'une courroie 18, ici souple, passe dans les gorges des réas 16 et 17 via des poulies de renvoi 19, 19'. On comprend aisément comment utiliser un engin selon l'invention. L'utilisateur s'assoie à califourchon sur la partie arrondie du cadre 1 , dans un sens ou dans l'autre (sauf bien sûr s'il est équipé de l'accessoire précédemment décrit), appuyant ses mains sur l'un des flotteurs 3, 3' et il peut alors aisément avancer ou reculer en effectuant des mouvements de pédalage ou de rétro-pédalage.The propeller 14 is also secured to a sheave 17 while a belt 18, here flexible, passes into the grooves of the sheaves 16 and 17 via pulleys 19, 19 '. It is easy to understand how to use a machine according to the invention. The user sits astride the rounded part of the frame 1, in one direction or the other (except of course if it is equipped with the previously described accessory), resting his hands on one of the floats 3, 3 'and can then easily advance or backward by performing pedaling or back pedaling movements.
Avec l'accessoire décrit à propos des figures 13 à 15, on comprend que l'engin peut alors être propulsé par un pédalage ou moyen du pédalier 13 réglable selon la taille de l'utilisateur.With the accessory described with reference to Figures 13 to 15, it is understood that the machine can then be propelled by pedaling or pedal means 13 adjustable according to the size of the user.
De nombreux accessoires et de nombreuses variantes peuvent être prévus sans sortir du cadre de l'invention.Many accessories and many variants can be provided without departing from the scope of the invention.
C'est ainsi par exemple que les têtes 2, 2' peuvent être équipées d'une boussole 20 et/ou d'un anneau d'amarrage 21 (figures 7 à 12), etc. De plus, outre des valves de gonflage pour les éléments gonflables, on peut prévoir des moyens complémentaires pour vider rapidement lesdits éléments (des valves de gonflage et des moyens de vidage sont représentés sur la figure 1 sans référence particulière pour ne pas surcharger inutilement ladite figure). Par ailleurs, si le cadre présente ici la forme d'un U ou d'une lyre, rien n'empêche bien sûr de prévoir un double U, c'est-à-dire un cadre en forme d'oméga minuscule avec trois flotteurs afin de constituer un engin biplace.For example, the heads 2, 2 'can be equipped with a compass 20 and / or a mooring ring 21 (FIGS. 7 to 12), etc. Moreover, in addition to inflating valves for the inflatable elements, additional means can be provided for rapidly emptying said elements (inflation valves and emptying means are shown in FIG. 1 without particular reference so as not to unnecessarily overload said FIG. ). Moreover, if the frame here has the shape of a U or a lyre, nothing prevents of course to provide a double U, that is to say a tiny omega-shaped frame with three floats in order to constitute a two-seater vehicle.
Pour bien montrer que l'invention propose essentiellement une conception simple, les figures 16 à 27 représentent trois modes de réalisation particulièrement simplifiés et peux onéreux.To show that the invention essentially provides a simple design, Figures 16 to 27 show three embodiments particularly simplified and can be expensive.
Dans les modes de réalisation décrits ci-après on a conservé les références générales 1 et 3, 3' pour respectivement le cadre et les flotteurs transversaux.In the embodiments described below, the general references 1 and 3, 3 'have been retained for the frame and the transverse floats, respectively.
Dans le mode de réalisation des figures 16 à 19, le cadre 1 comporte un élément rigide ou semi-rigide 1 c en forme au moins en partie de gouttière (figure 18) dans lequel est logé un élément gonflable 1d tandis que les flotteurs transversaux 3, 3' sont également sous la forme d'éléments gonflables éventuellement d'une seule pièce avec l'élément gonflable 1 d du cadre 1.In the embodiment of FIGS. 16 to 19, the frame 1 comprises a rigid or semi-rigid element 1c shaped at least in part as a gutter (FIG. 18) in which an inflatable element 1d is housed while the transverse floats 3 3 'are also in the form of inflatable elements possibly in one piece with the inflatable element 1 d of the frame 1.
Ce mode de réalisation simplifié est peu encombrant comme le montre la figure 19 lorsque les éléments gonflables sont dégonflés.This simplified embodiment is not bulky as shown in Figure 19 when the inflatable elements are deflated.
Par ailleurs dans ce mode de réalisation, on a prévu des bras supports gonflables tels que 22 disposés entre les flotteurs 3, 3' transversaux et l'élément gonflable 1 d du cadre 1.Furthermore, in this embodiment, there are provided inflatable support arms such as 22 arranged between the transverse floats 3, 3 'and the inflatable element 1 d of the frame 1.
Dans les modes de réalisation des figures 20 à 23 d'une part, et 24 à 27 d'autre part, le cadre 1 est également formé d'un élément gonflable 1 d comme dans le mode de réalisation des figures 16 à 19 mais ici, on a prévu une armature interne 1e fixée par exemple par collage dans ledit élément gonflable 1d.In the embodiments of Figures 20 to 23 on the one hand, and 24 to 27 on the other hand, the frame 1 is also formed of an inflatable element 1 d as in the embodiment of Figures 16 to 19 but here there is provided an internal frame 1e fixed for example by gluing in said inflatable member 1d.
Les flotteurs transversaux 3, 3' sont également dans ces deux modes de réalisation des éléments gonflables. Toutefois, si dans le mode de réalisation des figures 20 à 23 on retrouve les bras supports 22 du mode de réalisation précédent des figures 16 à 19, dans le mode de réalisation des figures 24 à 27, on a prévu un élément rigide ou semi-rigide 3c, d'une manière un peu analogue à l'âme 3a, 3'a des figures 3 à 12.The transverse floats 3, 3 'are also in these two embodiments of the inflatable elements. However, if in the embodiment of FIGS. 20 to 23 there are the support arms 22 of the preceding embodiment of FIGS. 16 to 19, in the embodiment of FIGS. 24 to 27, a rigid or semi-rigid element is provided. rigid 3c, in a manner somewhat similar to the core 3a, 3'a of Figures 3 to 12.
Toutefois ici, l'élément rigide 3c est avantageusement pourvu d'un mécanisme de pliage 23 (figure 26). However, here the rigid element 3c is advantageously provided with a folding mechanism 23 (FIG. 26).
