Abstract
Description
L'invention a trait à un appareil d'entrainement pour la marche ou la course à pied destiné essentiellement à un usage domestique. The invention relates to a training device for walking or running intended essentially for domestic use.
Pour le maintien physique d'une personne, on connaît déjà différents appareils d'entraînement. Un de ces appareils a une forme approximative d'une bicyclette comportant un cadre fréquemment fixé au sol et servant de support à un pédalier et à une selle. A l'avant de cet appareil est prévue une barre de maintien pourvue d'un dispositif de freinage agissant sur le pédalier permettant de modifier l'effort à fournir pour faire tourner le pédalier. Ainsi, on peut obtenir un double effet en combinant la vitesse de rotation du pédalier avec l'effort musculaire nécessaire. Various physical training devices are already known for the physical support of a person. One of these devices has an approximate shape of a bicycle comprising a frame frequently fixed to the ground and serving as a support for a crankset and a saddle. At the front of this device is provided a retaining bar provided with a braking device acting on the crankset making it possible to modify the force to be supplied to turn the crankset. Thus, a double effect can be obtained by combining the speed of rotation of the crankset with the necessary muscular effort.
Par ailleurs, on connaît également pour l'entraînement pour la marche ou la course à pied des tapis roulants. Cependant, ces appareils connus sont très onéreux et très complexes. En raison de la complexité des composants, ces tapis roulants sont peu fiables. Furthermore, treadmills are also known for training for walking or running. However, these known devices are very expensive and very complex. Due to the complexity of the components, these treadmills are unreliable.
La présente invention a pour but de fournir un appareil simplifié à usage domestique permettant un entraînement musculaire sous la forme d'une marche ou dlune course à pied. Non seulement le prix de revient de cet appareil est relativement peu important mais ledit appareil est beaucoup plues fiable que les appareils connus. The object of the present invention is to provide a simplified appliance for domestic use allowing muscular training in the form of a walk or a running race. Not only the cost price of this device is relatively unimportant but said device is much more reliable than known devices.
A cet effet) l'invention concerne un appareil d'entraînement pour la marche ou la course à pied destiné essentiellement à un usage domestique caractérisé en ce qu'il comporte un tapis sans fin entraîné par des moyens moteurs à vitesse variable, le tout monté sur une ossature formant un angle variable avec le sol
L'invention sera bien compris en se référant à la description suivante faite à titre d'exemple non limitatif et au dessin ci-annexé dans le que - la figure l est une vue en élévation de l'appareil d'entraînement conforme à l'invention la la figure 2 est une vue en plan de cet appareil - la figure 3 esc une vue partielle en élévation d'une variante du dispositif permettan de varier la vitesse d'avance du tapis sans fin - la figut est une vue partielle en elé-vation du dispositif de variation de vitesse réalise selon un autre mode d'exécution - la figure 5 est une vue partielle en élévation d'une variante du dispositif realisé selon llautre mode d'exécution
On se réfère aux figures 1 et 2.To this end) the invention relates to a training device for walking or running intended essentially for domestic use, characterized in that it comprises an endless belt driven by variable speed motor means, all mounted. on a frame forming a variable angle with the ground
The invention will be better understood by referring to the following description given by way of nonlimiting example and to the attached drawing in that - Figure 1 is an elevational view of the drive apparatus according to FIG. 2 is a plan view of this device - FIG. 3 is a partial elevation view of a variant of the device allowing the speed of advance of the endless belt to be varied - FIG. -vation of the speed variation device produced according to another embodiment - Figure 5 is a partial elevation view of a variant of the device produced according to the other embodiment
We refer to Figures 1 and 2.
L'appareil 1, destiné essentiellement à l'entraînement pour la mar che et/ou la course à pied et à usage domestique, comporte un tapis sans fin 2. Celui-ci s'enroule partiellement autour d'un tambour mené 3 et d'un tambour moteur 4 et le dessus se déplace vers le tambour mené 3. Le tambour moteur 4 comporte un arbre 5 dont l'extrémité 6 est pourvue d'une poulie menée 7 reliée par au moins une courroie 8 à une poulie motrice 9. The apparatus 1, intended essentially for training for walking and / or running and for domestic use, comprises an endless belt 2. This partially wraps around a driven drum 3 and d a driving drum 4 and the top moves towards the driven drum 3. The driving drum 4 comprises a shaft 5, the end 6 of which is provided with a driven pulley 7 connected by at least one belt 8 to a driving pulley 9.
Cette poulie motrice 9, composée de deux flasques 10, 11 coulissant axialement mais rendus solidaires l'un de l'autre au niveau du déplacement angulaire, est montée sur l'arbre 12 d'un moteur 13. Les deux flasques 10, 11 sont à rappel élastique grâce à des éléments élastiques 14, 15 montés sur ledit arbre 12. Chaque flasque 10, 11 comporte une face tronconique 16, 17, les faces tronconiques 16, 17 étant dirigées vers le plan médian 18 de la courroie 8. Ces faces tronconiques 16, 17 assurent l'entraînement de ladite courroie 8.This drive pulley 9, composed of two flanges 10, 11 sliding axially but made integral with one another at the level of the angular displacement, is mounted on the shaft 12 of a motor 13. The two flanges 10, 11 are with elastic return thanks to elastic elements 14, 15 mounted on said shaft 12. Each flange 10, 11 has a frustoconical face 16, 17, the frustoconical faces 16, 17 being directed towards the median plane 18 of the belt 8. These faces frustoconical 16, 17 drive said belt 8.
Pour obtenir un écartement des deux flasques 10, 11 en vue de modifier le diamètre d'enroulement de la courroie 8 sur la poulie motrice 9 et ainsi modifier la vitesse d'avance du tapis sans fin 2, on intercale sur le brin mené 19 de la courroie 8 un galet supplémentaire 20. En raison de sa position particuliere, on évite un basculement du moteur 13. Du fait que le galet supplémentaire 20 se trouve sur le brin mené 19 et non pas sur le brin moteur 21, il n'est pas nécessaire de modifier ltentr'axes 22 entre la poulie motrice 9 et la poulie menée 7. To obtain a spacing of the two flanges 10, 11 in order to modify the winding diameter of the belt 8 on the drive pulley 9 and thus modify the speed of advance of the endless belt 2, the interposed strand 19 of the belt 8 an additional roller 20. Due to its particular position, the motor 13 is tipped over. Because the additional roller 20 is located on the driven strand 19 and not on the motor strand 21, it is not no need to modify the axis 22 between the drive pulley 9 and the driven pulley 7.
L'appareil 1 comporte des moyens de déplacement du galet supplémentaire 20. Celui-ci tourne librement sur un axe 23 traversant une lumière oblongue 24 réalisée dans un des montants 25, 26 d'une barre d'appui 27. The apparatus 1 comprises means for moving the additional roller 20. The latter freely rotates on an axis 23 passing through an oblong slot 24 produced in one of the uprights 25, 26 of a support bar 27.
Cet axe 23 est solidaire d'un coulisseau tel qu'un écrou immobilisé en rotation mais pouvant coulisser le long d'un arbre de commande 28 formé par une tige filetée. Celle-ci comporte à sa partie supérieure 29 une poignée de manoeuvre 30. L'arbre de commande 28 est libre en rotation mais est immobilise en translation. Ainsi, en tournant l'arbre de commande 28 à l'aide de la poignée de manoeuvre 30, on provoque le déplacement du coulisseau et, par voie de conséquence, du galet supplémentaire 20. Celui-ci exerce soit une traction (voir figure 1), soit une poussée (voir figure 3) sur le brin mené 19 de la courroie 8 et on modifie la tension de la courroie 8.This axis 23 is integral with a slide such as a nut immobilized in rotation but which can slide along a control shaft 28 formed by a threaded rod. The latter comprises at its upper part 29 an operating handle 30. The control shaft 28 is free to rotate but is immobilized in translation. Thus, by turning the control shaft 28 using the operating handle 30, the slide is displaced and, consequently, the additional roller 20. This exerts either a traction (see FIG. 1 ), or a push (see FIG. 3) on the driven strand 19 of the belt 8 and the tension of the belt 8 is modified.
De ce fait, la courroie 8 exerce une pression sur les faces tronconiques 16, 17 des flasques 10, 11 en provoquant leur écartement. La courroie 8 se rapproche du centre de rotation 31 de la poulie motrice 9 et on modifie le rapport de transmission entre la poulie menée 7 et la poulie motrice 9.Therefore, the belt 8 exerts pressure on the frustoconical faces 16, 17 of the flanges 10, 11 causing them to separate. The belt 8 approaches the center of rotation 31 of the drive pulley 9 and the transmission ratio between the driven pulley 7 and the drive pulley 9 is modified.
Ainsi, on modifie la vitesse de rotation de la poulie menée 7 et, par voie de conséquence, la vitesse d'avance du tapis sans fin 2.Thus, the speed of rotation of the driven pulley 7 and, consequently, the speed of advance of the endless belt 2 is modified.
Selon un autre mode de réalisation, la manoeuvre de l'arbre de commande 28 ne se fait plus manuellement à l'aide de la poignée 30 mais peut se faire par l'intermédiaire d'un moteur. According to another embodiment, the operation of the control shaft 28 is no longer done manually using the handle 30 but can be done by means of a motor.
Selon un autre mode d'exécution, le galet supplémentaire 20 est monté sur un levier 32 pivotant autour d'un axe de rotation 33. Le relèvement ou l'abaissement du levier 32 et, par voie de conséquence, le relèvement ou l'abaissement du galet supplémentaire 20 peut se faire à l'aide d'un dispositif équivalent à celui agissant sur le galet 20 monté sur le coulisseau. According to another embodiment, the additional roller 20 is mounted on a lever 32 pivoting about an axis of rotation 33. Raising or lowering the lever 32 and, consequently, raising or lowering additional roller 20 can be done using a device equivalent to that acting on the roller 20 mounted on the slide.
En figure 4, le galet 20 monté sur le levier 32 exerce une traction sur le brin mené 19 de la courroie 8 analogue à celle visible dans la figure 1, la figure 5 montrant le galet 20 exerçant une poussée analogue à celle visible dans la figure 3. In FIG. 4, the roller 20 mounted on the lever 32 exerts traction on the driven strand 19 of the belt 8 similar to that visible in FIG. 1, FIG. 5 showing the roller 20 exerting a thrust similar to that visible in the FIG. 3.
L'appareil 1 comporte une ossature 34 présentant un support 35 sur lequel est fixé le moteur 13. Le tambour moteur 4 est maintenu par des paliers 36, 37 alors que le tambour mené 3 à paliers internes est maintenu par des supports 38, 39. The apparatus 1 comprises a frame 34 having a support 35 on which the motor 13 is fixed. The motor drum 4 is held by bearings 36, 37 while the driven drum 3 with internal bearings is held by supports 38, 39.
Pour éviter que le poids de l'usager provoque une flèche du brin supérieur 45 du tapis sans fin 2, on dispose sous ce brin supérieur 45 un support sous forme d'un panneau 46 sur lequel glisse le tapis sans fin 2 mais pouvant supporter le poids de l'usager. To prevent the weight of the user causing an arrow of the upper strand 45 of the endless belt 2, there is provided under this upper strand 45 a support in the form of a panel 46 on which the endless belt 2 slides but which can support user weight.
Pour compenser le relâchement de la tension du tapis sans fin 2, on pourvoit les paliers 3S, 39 du tambour mené 3 d'un dispositif de réglage 40 permettant de modifier l'entr'axes 41 entre le tambour mené 3 et le tambour moteur 4. To compensate for the loosening of the tension of the endless belt 2, the bearings 3S, 39 of the driven drum 3 are provided with an adjustment device 40 making it possible to modify the distance between axes 41 between the driven drum 3 and the motor drum 4 .
L'ossature 34, formant un certain angle avec le sol 42, présente des pieds 43, 44. Avantageusement, les pieds 44 comportent un dispositif de réglage permettant de modifier la hauteur de ces pieds 44. De ce fait, on petit modifier l'inclinaison de l'appareil 1 par rapport au sol 42. Ainsi, il est possible de modifier l'effort que doit fournir l'usager alors que li cadence de sa course est fonction de la vitesse d'avance du tapis sans fin 2. The frame 34, forming a certain angle with the ground 42, has feet 43, 44. Advantageously, the feet 44 include an adjustment device making it possible to modify the height of these feet 44. Therefore, we can modify the inclination of the apparatus 1 relative to the ground 42. Thus, it is possible to modify the effort which the user must provide while the cadence of his run is a function of the speed of advance of the endless belt 2.
Ben que l'invention ait été décrite à propos d'une forme de réalistation particulière, il est bien entendu qu'elle n'y est nullement limitée et qu'on peut y apporter diverses modifications de formes, de matériaux et de combinaisons de ces divers éléments, sans pour cela s'éloigner du cadre et de I 'esprit de l'invention. Although the invention has been described in connection with a particular embodiment, it is understood that it is in no way limited thereto and that it is possible to make various modifications to it in terms of shapes, materials and combinations of these. various elements, without departing from the scope and spirit of the invention.
