Abstract
Description
La présente invention est relative à une bicyclette d'entrainement et de rééducation en appartement, appelée ci-après bicyclette d'appartement, conçue notamment de façon à répondre aux deux préoccupations suivantes - permettre la rééducation médicale après des troubles cardiaques, des
traumatismes, des fractures, des tendinites, etc.The present invention relates to a training and rehabilitation bicycle in an apartment, hereinafter called an exercise bicycle, designed in particular to respond to the following two concerns - enabling medical rehabilitation after cardiac disorders,
trauma, fractures, tendonitis, etc.
- assurer un maintien en bonne~condition physique, un entrainement sportif,
etc.- maintain good physical condition, sports training,
etc.
Il existe à ltheure actuelle sur le marché un certain nombre de dispositifs permettant de s'entrafner chez soi à la pratique de la bicyclette. Ces dispositifs connus peuvent être classés en deux catégories 1 - les entraîneurs dénommés encore "home trainers", qui consistent en un
châssis s'adaptant sur toute bicyclette, de façon que les roues avant et
arrière reposent sur des rouleaux. Ces entraîneurs nécessitent obliga
toirement la possession d'une bicyclette, et, de ce fait, ils présentent
un encombrement trop important. De plus, leur mise en oeuvre, notam
ment pour les enfourcher, exige une certaine virtuosité de la part de
l'utilisateur, ce qui les rend inaptes à la rééducation des infirmes, ma
lades et handicapés, ainsi qu'à leur utilisation par des personnes âgées.There are currently a number of devices on the market to train at home in the practice of cycling. These known devices can be classified into two categories 1 - trainers also called "home trainers", which consist of
chassis that fits on any bicycle, so that the front wheels and
rear rest on rollers. These coaches require obliga
the possession of a bicycle, and therefore
too much space. In addition, their implementation, in particular
to ride them, requires a certain virtuosity on the part of
the user, which makes them unsuitable for the rehabilitation of the disabled, my
lades and handicapped, as well as their use by the elderly.
2 - les bicyclettes dites d'appartement. Il s'agit la de dispositifs conçus
uniquement en vue d'une utilisation en appartement. Dans ces dispositifs,
la résistance au mouvement de pédalage est obtenue par un freinage cons
tant du démarrage à la fin du pédalage, ce freinage pouvant s'exercer
soit sur une roue, soit sur un type particulier de pédalier.2 - the so-called apartment bicycles. These are devices designed
only for use in an apartment. In these devices,
resistance to pedaling movement is obtained by cons braking
both from start to end of pedaling, this braking can be exerted
either on a wheel or on a particular type of crankset.
La présente invention vise une bicyclette d'appartement du type appartenant a la seconde catégorie ci-dessus. Toutefois, de par sa conception nouvelle, elle vise aussi -en partie à se substituer aux entrameurs classiques dits "home-trainers". Cette nouvelle bicyclette se propose de pallier les inconvénients des bicyclettes connues.En effet, avec les bicyclettes d'appartement selon la technique antérieure, le pédalage n'a rien de comparable à celui d'une bicyclette réelle, qui permet un pédalage coulé et souple, que les cyclistes nomment le "jeu de cheville'T. L'invention se propose d'apporter une bicyclette d'appartement offrant des réactions comparables à celles d'une vraie bicyclette, c'est-à-dire permettant un pédalage en souplesse et non en force, d'où une plus grande vitesse à dépense musculaire égale ou permettant de pédaler plus longtemps, à vitesse plus lente. The present invention relates to an exercise bicycle of the type belonging to the second category above. However, due to its new design, it also aims - in part to replace the conventional trainers known as "home trainers". This new bicycle proposes to overcome the disadvantages of known bicycles. Indeed, with stationary bicycles according to the prior art, pedaling has nothing comparable to that of a real bicycle, which allows a smooth and flexible pedaling , which cyclists call the "ankle game". The invention proposes to provide an exercise bicycle offering reactions comparable to those of a real bicycle, that is to say allowing flexible pedaling. and not in strength, hence greater speed with equal muscular expenditure or making it possible to pedal longer, at slower speed.
La bicyclette d'appartement selon la présente invention comprend une partie fixe, constituée d'un châssis tubulaire portant au moins un rouleau sur lequel doit reposer une roue de la bicyclette, et dont l'un des tubes reçoit la tige de potence du guidon, et une partie mobile qui comprend le cadre de la bicyclette, un pédalier complet, une roue de bicyclette, et une barre de jonction reliant ladite partie mobile à la partie fixe. Cette bicyclette est caractérisée en ce que ladite barre de jonction est positionnée de façon sensiblement horizontale, afin que la poussée due au pédalage soit, elle aussi, horizontale. The stationary bicycle according to the present invention comprises a fixed part, consisting of a tubular frame carrying at least one roller on which a wheel of the bicycle must rest, and one of the tubes of which receives the stem of the handlebar, and a movable part which comprises the frame of the bicycle, a complete crankset, a bicycle wheel, and a connecting bar connecting said movable part to the fixed part. This bicycle is characterized in that said junction bar is positioned in a substantially horizontal manner, so that the thrust due to pedaling is also horizontal.
Selon une autre caractéristique de cette invention,- on prévoit des moyens permettant de réaliser la simulation des côtes, notamment par soulèvement de la partie avant du châssis fixe. On peut, à cet effet, utiliser des vérins, ou tout autre système équivalent. According to another characteristic of this invention, - means are provided for carrying out the simulation of the ribs, in particular by lifting the front part of the fixed frame. It is possible, for this purpose, to use jacks, or any other equivalent system.
Selon une autre caractéristique de cette invention, la résistance of- ferte au pédalage varie en fonction du poids du cycliste, étant donné qu'elle est due à ce poids, comme dans le cas d'une vraie bicyclette. According to another characteristic of this invention, the resistance offered for pedaling varies according to the weight of the cyclist, since it is due to this weight, as in the case of a real bicycle.

On se réfère en premier lieu aux Figures 1 et 2, qui représentent le premier exemple de réalisation de la bicyclette d'appartement selon l'invention. Ainsi qu'on peut le voir sur ces Figures, cette bicyclette comprend deux parties essentielles - une partie fixe, désignée dans son ensemble par la référence A ; et, - une partie mobile, désignée dans son ensemble par la référence B. Reference is firstly made to FIGS. 1 and 2, which represent the first embodiment of the exercise bicycle according to the invention. As can be seen in these Figures, this bicycle comprises two essential parts - a fixed part, generally designated by the reference A; and, - a mobile part, designated as a whole by the reference B.
La partie fixe A comprend essentiellement : un châssis 10, entretoisé en 12 et 14 et portant les rouleaux 16, 18 ; un tube 20 dans lequel s'embotte la tige de potence 22 du guidon, réglable en hauteur et triangulé par le montant 24 et le guidon 26, réglable en écartement et en inclinaison. The fixed part A essentially comprises: a frame 10, braced at 12 and 14 and carrying the rollers 16, 18; a tube 20 in which the stem stem 22 of the handlebar is set, adjustable in height and triangulated by the upright 24 and the handlebar 26, adjustable in spacing and inclination.
La partie mobile B comprend : le cadre 28, avec le tube de selle 30 et la selle 32 réglables ; un pédalier complet 34 (ctest-à-dire avec manivelles, couronne (s), pédales, cale-pieds, éventuellement cache-chaine, dérailleur, etc.) ; une roue de bicyclette complète 36, recevant soit un pignon fixe, soit une roue libre à une ou plusieurs couronnes, et pouvant être équipée d'un dérailleur ou d'un moyeu à changement de vitesse ; une barre de jonction 38, reliant la partie mobile B à l'axe de pivotement 40 de la partie fixe A. The movable part B comprises: the frame 28, with the adjustable seat tube 30 and the saddle 32; a complete crankset 34 (that is to say with cranks, crown (s), pedals, toe clips, possibly chain cover, derailleur, etc.); a complete bicycle wheel 36, receiving either a fixed pinion or a free wheel with one or more crowns, and being able to be equipped with a derailleur or with a gear change hub; a junction bar 38, connecting the movable part B to the pivot axis 40 of the fixed part A.
Selon une caractéristique de cette invention, la barre de jonction 38 est positionnée sensiblement horizontalement, afin que la poussée due au pédalage soit également sensiblement horizontale, évitant ainsi qu'unie partie du poids du cycliste ne se reporte sur l'axe de pivotement 40. According to a characteristic of this invention, the junction bar 38 is positioned substantially horizontally, so that the thrust due to pedaling is also substantially horizontal, thus preventing a portion of the weight of the cyclist from being transferred to the pivot axis 40.
La bicyclette selon l'invention est pourvue de moyens permettant de simuler une côte, en modifiant la position en hauteur de la partie avant du châssis fixe A. The bicycle according to the invention is provided with means making it possible to simulate a hill, by modifying the height position of the front part of the fixed frame A.
Dans l'exemple de réalisation représenté à la Figure 3, ces moyens consistent en des vérins 42, 42', prenant appui sur l'entretoise 12 et poussant sur une barre 44, guidée par des coulisseaux 46, 46'. In the embodiment shown in Figure 3, these means consist of cylinders 42, 42 ', bearing on the spacer 12 and pushing on a bar 44, guided by slides 46, 46'.
Dans la variante illustrée par la Figure 7, on utilise un tube 48 qui coulisse dans le tube 20 en appuyant sur la barre 44,qui, ici aussi, est guidée par les deux coulisseaux 46, 46'. Le tube 48 peut être maintenu à des hauteurs variables par une tige de serrage 51. In the variant illustrated in FIG. 7, a tube 48 is used which slides in the tube 20 by pressing on the bar 44, which, here too, is guided by the two slides 46, 46 '. The tube 48 can be held at variable heights by a clamping rod 51.
Dans tous les exemples de réalisation, la barre 44 est pourvue d'une partie antidérapante sur sa surface en contact avec le sol. In all the exemplary embodiments, the bar 44 is provided with a non-slip part on its surface in contact with the ground.
Grâce à ces dispositions, on peut obtenir une position côte qui simule une pente pouvant varier, par exemple, de 1" à 20" (Figure 6). Bien entendu, les deux modes d'exécution décrits ici,en référence aux Figures 3 et 7, ne constituent que des exemples non limitatifs, tout autre moyen permettant de surélever la partie avant du chassis fixe A pouvant être utilisé sans sortir du cadre de l'invention. Thanks to these arrangements, a side position can be obtained which simulates a slope which can vary, for example, from 1 "to 20" (Figure 6). Of course, the two embodiments described here, with reference to Figures 3 and 7, are only non-limiting examples, any other means for raising the front part of the fixed frame A can be used without departing from the scope of the 'invention.
La variante de réalisation représentée à la Figure 4 comporte une partie fixe A' n'ayant qu'un seul rouleau 50, sur lequel appuie la roue 36 de la bicyclette. Dans la variante illustrée par la Figure 5, la partie fixe A" comporte un seul rouleau, placé soit à gauche, 50', soit à droite, 50", de l'axe vertical de la r-oue 36. The variant embodiment shown in FIG. 4 comprises a fixed part A ′ having only one roller 50, on which the wheel 36 of the bicycle rests. In the variant illustrated in FIG. 5, the fixed part A "comprises a single roller, placed either to the left, 50 ′, or to the right, 50", from the vertical axis of the line 36.
Les Figures 8 à 10 illustrent des variantes de réalisation d'une bicyclette d'appartement selon l'invention adaptée au pédalage horizontal. Sur ces variantes, on retrouve les m8mes caractéristiques fondamentales que celles décrites ci-dessus, en référence aux Figures 1 à 7. La Figure 9 illustre la position côte de la bicyclette représentée à la Figure 8, et la Figure 10 représente une variante dans laquelle la position du cycliste est face au sol, position utilisée pour la rééducation de certains handicapés, ou dans des cas très spéciaux. Figures 8 to 10 illustrate alternative embodiments of an exercise bicycle according to the invention suitable for horizontal pedaling. On these variants, we find the same basic characteristics as those described above, with reference to Figures 1 to 7. Figure 9 illustrates the side position of the bicycle shown in Figure 8, and Figure 10 shows a variant in which the cyclist's position is facing the ground, a position used for the rehabilitation of certain disabled people, or in very special cases.
La bicyclette d'appartement selon l'invention apporte les avantages suivants par rapport aux bicyclettes d'appartement de type connu - possibilité de réaliser un pédalage souple et coulé comparable à celui
d'une vraie bicyclette, grâce à la poussée horizontale du pédalage - résistance au pédalage variable, selon
le poids de l'utilisateur;
la vitesse choisie
la position côte adoptée - grande stabilité permettant, notamment, un pédalage facile d'une seule
jambe (alternativement) pour l'apprentissage du jeu de cheville, ou encore
pour effectuer une rééducation particulière; - possibilité de réglages multiples, pour adapter la bicyclette aux mensura
tions de l'utilisateur; ; - possibilité de prévoir un changement de vitesse, soit par dérailleurs,
arrière et avant et arrière, soit par un changement de vitesse dans le
moyeu, ce qui permet de faire varier la résistance dans d'importantes mesures. The stationary bicycle according to the invention provides the following advantages compared to known type stationary bicycles - possibility of achieving flexible and flowable pedaling comparable to that
of a real bicycle, thanks to the horizontal pedaling thrust - variable pedaling resistance, depending on
the weight of the user;
the chosen speed
the hill position adopted - high stability allowing, in particular, easy pedaling with just one
leg (alternately) for learning the ankle game, or
to perform special rehabilitation; - possibility of multiple adjustments, to adapt the bicycle to the mensura
user tions; ; - possibility of providing for a gear change, either by derailleurs,
rear and front and rear, either by a gear change in the
hub, which makes it possible to vary the resistance in important measurements.
La bicyclette d'appartement selon l'invention peut être utilisée par tous : handicapés, sportifs, et toute personne désirant se conserver en bonne condition physique, se rééduquer ou améliorer sa ligne. The exercise bicycle according to the invention can be used by all: the disabled, sportspeople, and any person wishing to keep in good physical condition, to rehabilitate or improve their line.
I1 demeure bien entendu que cette invention n'est pas limitée aux divers exemples de réalisation décrits et représentés, mais qu'elle en englobe toutes les variantes. I1 remains of course that this invention is not limited to the various embodiments described and shown, but that it encompasses all variants.
