Description

L'invention a pour objet un tapis roulant ergométrique perfectionné.The invention relates to an improved ergometric treadmill.

L'invention se rattache au matériel et équipement permettant l'entrainement de sportifs notamment, mais également autorisant la rééducation des personnes. Ce matériel est également adapté pour effectuer des travaux de recherche à des fins physiologiques et biomécaniques..The invention relates to materials and equipment allowing the training of sportsmen in particular, but also authorizing the rehabilitation of people. This material is also suitable for carrying out research work for physiological and biomechanical purposes.

On connait déjà des tapis roulants motorisés susceptibles de recréer le déplacement relatif d'un coureur par rapport à une piste en rendant celle-ci mobile. Ainsi la piste est constituée par un tapis en forme de courroie sans fin entre deux cylindres ou rouleaux de renvoi et entrainée par un moteur électrique dont la vitesse est constante. Dans cette mise en oeuvre, le niveau de vitesse est ajustable ou préréglée par un système d'asservissement. Ainsi le coureur est alors immobile par rapport à l'environnement ce qui permet un entrainement en salle à vitesse constante et facilite la saisie uniquementdes données physiologiques.Motorized treadmills are already known which are capable of recreating the relative movement of a runner relative to a track by making the latter mobile. Thus the track is constituted by a belt in the form of an endless belt between two cylinders or idler rollers and driven by an electric motor whose speed is constant. In this implementation, the speed level is adjustable or preset by a servo system. Thus the runner is then immobile with respect to the environment which allows training in the gym at constant speed and facilitates the entry of physiological data only.

Les tapis roulants motorisés de ce type présentent cependant des limites d'utilisation et certains inconvénients qui sont :
- pour l'athlète une vitesse imposée ne permettant pas le sprint, ni de moduler la puissance de course.
- pour l'entraineur, le chercheur, et d'une manière plus générale le bio-mécanicien chargé d'établir les essais et tests d'en apprécier les résultats, l'impossibilité pour lui de mesurer la puissance mécanique externe fournie lors de la course.
Un premier but recherché selon l'invention était donc de proposer un appareil offrant plus de souplesse d'utilisation et permettant de mesurer l'effort de l'utilisateur dans différentes situations de course, rapide telle que sprint, régulière ou de désaccélération.Motorized treadmills of this type, however, have limits of use and certain disadvantages which are:
- for the athlete a set speed not allowing the sprint, nor to modulate the running power.
- for the trainer, the researcher, and more generally the bio-mechanic responsible for establishing the trials and tests to assess the results, the impossibility for him to measure the external mechanical power supplied during the race.
A first aim sought after according to the invention was therefore to propose a device offering more flexibility of use and making it possible to measure the effort of the user in different racing situations, fast such as sprint, regular or deceleration.

Un autre but de l'invention était de proposer un appareil permettant de mesurer la puissance de l'utilisateur dans les différentes situations de course considérée.Another object of the invention was to propose an apparatus making it possible to measure the power of the user in the different racing situations considered.

Un autre but selon l'invention était de concevoir un appareil de conception simple, peu coûteux autorisant une mesure simultanée de divers autres paramètres.Another object according to the invention was to design an apparatus of simple design, inexpensive allowing simultaneous measurement of various other parameters.

Ces buts et d'autres encore ressortiront bien de la suite de la description.These goals and others will become apparent from the following description.

Selon une première caractéristique de l'invention, le tapis roulant comprend une bande sans fin disposée en tension entre deux rouleaux positionnés et maintenus sur un chassis porteur, le coureur étant en action sur le brin supérieur du tapis, lui-même maintenu par une plaque support associée au châssis entraînant le tapis, caractérisé en ce que le coureur assure lui-même le mouvement et l'entrainement du tapis roulant en modulant et régulant lui-même la vitesse de défilement du tapis, et en ce que le coureur est attaché à une ceinture elle-même associée par des moyens au chassis porteur du tapis, en ayant une liberté de mouvement dans les plans vertical et latéral, et non pas dans le plan frontal ou de déplacement du tapis et en ce que des moyens de mesure sont disposés sur le moyen d'attache et de liaison du coureur et sur le tapis roulant autorisant l'enregistrement et le calcul de certains paramètres tels que la puissance verticale instantanéeet la puissance horizontale instantanée du coureur.According to a first characteristic of the invention, the treadmill comprises an endless belt arranged in tension between two rollers positioned and held on a carrying frame, the runner being in action on the upper strand of the mat, itself held by a plate support associated with the chassis driving the treadmill, characterized in that the runner himself ensures the movement and the training of the treadmill by modulating and regulating himself the speed of movement of the treadmill, and in that the runner is attached to a belt itself associated by means with the carrying frame of the mat, having a freedom of movement in the vertical and lateral planes, and not in the frontal plane or of movement of the mat and in that measuring means are arranged on the runner's attachment and connection means and on the treadmill authorizing the recording and calculation of certain parameters such as the instantaneous vertical power and the power this instant horizontal runner.

Ces caractéristiques et d'autres encore ressortiront bien de la suite de la description.These characteristics and others will emerge clearly from the following description.

    - the evolution of the instantaneous external mechanical power (in watts) as a function of time (in seconds), being the sum of the two previous measurements.

Afin de rendre plus concret l'objet de l'invention, on le décrit maintenant d'une manière non limitative illustrée aux figures des dessins.In order to make the object of the invention more concrete, it is now described in a nonlimiting manner illustrated in the figures of the drawings.

Le tapis roulant ergométrique selon l'invention est établi à partir d'un concept de fonctionnement différent de l'art antérieur à savoir que c'est le coureur qui met lui-même en mouvement et entraine le tapis roulant, en pouvant ainsi moduler à volonté les différents effets ou situations de course recherchés.The ergometric treadmill according to the invention is established on the basis of an operating concept different from the prior art, namely that it is the runner who himself sets in motion and drives the treadmill, thus being able to modulate will the different effects or racing situations sought.

A cet effet, le tapis roulant est référencé dans son ensemble par (1) et comprend une bande sans fin disposée en tension entre deux rouleaux (2), ceux-­ci sont convenablement positionnés et maintenus par des supports (3) sur un châssis porteur (4). Le brin supérieur du tapis roulant est lui-même maintenu par une plaque ou support (18) associée au châssis.For this purpose, the treadmill is referenced as a whole by (1) and comprises an endless belt arranged in tension between two rollers (2), these are suitably positioned and held by supports (3) on a carrying frame. (4). The upper strand of the treadmill is itself held by a plate or support (18) associated with the chassis.

Le coureur (C) se tient sur le brin supérieur du tapis et est maintenu en position fixe par une ceinture (5) fixée autour de sa taille, ladite ceinture étant solidarisée du côté du dos de l'utilisateur à une barre de maintien (6). Celle-ci est articulée à l'une de ses extrémités (6,1) à la partie supérieure d'une console (7) verticale dans la partie arrière du châssis porteur (4). L'articulation de la barre permet des déplacements verticaux et horizontaux de l'utilisateur mais non ses déplacements frontaux, c'est-à-dire vers l'avant, ou vers l'arrière dans le sens de déplacement du tapis.The runner (C) stands on the upper side of the mat and is held in a fixed position by a belt (5) fixed around his waist, said belt being secured on the side of the user's back to a grab bar (6 ). The latter is articulated at one of its ends (6,1) to the upper part of a console (7) vertical in the rear part of the carrying frame (4). The articulation of the bar allows vertical and horizontal movements of the user but not his frontal movements, that is to say forward, or backward in the direction of movement of the mat.

Des capteurs montés sur le tapis roulant et la barre de maintien sont reliés à un moyen d'enregistrement (7) du type par exemple un interface électronique et permettent d'obtenir des signaux électroniques (tension analogique) correspondant aux données suivantes :
- Vitesse du tapis roulant
- force de traction horizontale du coureur.
- déplacement vertical du coureur.Sensors mounted on the conveyor belt and the holding bar are connected to a recording means (7) of the type, for example an electronic interface, and make it possible to obtain electronic signals (analog voltage) corresponding to the following data:
- Treadmill speed
- horizontal traction force of the runner.
- vertical movement of the runner.

Le calcul de la vitesse du tapis roulant entrainé par l'utilisateur est réalisé par un signal généré par un moyen du type codeur optique (8) associé à un convertisseur fréquence-tension monté sur l'axe de l'un des cylindres de renvoi et d'entrainement du tapis.The speed of the conveyor belt driven by the user is calculated by a signal generated by means of the optical encoder type (8) associated with a frequency-voltage converter mounted on the axis of one of the return cylinders and mat training.

Le calcul des forces horizontales exercées par le coureur ou utilisateur est réalisé à partir d'un signal généré par un moyen (9) du type capteur de force par exemple à jauges de contrainte monté sur la barre de maintien.The horizontal forces exerted by the runner or user are calculated from a signal generated by means (9) of the force sensor type, for example with strain gauges mounted on the support bar.

Le calcul du déplacement vertical du coureur est réalisé à partir d'un signal généré par un moyen (10) par exemple du type potentiomètre situé sur l'axe de rotation de la barre de maintien.The vertical displacement of the runner is calculated from a signal generated by means (10), for example of the potentiometer type, located on the axis of rotation of the grab bar.

Les différents moyens (8, 9, et 10) sont connectés à l'interface électronique (7) précité qui permet en liaison avec des traceurs (11, 12 et 13) d'imprimer et visualiser les résultats constatés.The various means (8, 9, and 10) are connected to the aforementioned electronic interface (7) which allows, in conjunction with plotters (11, 12 and 13) to print and view the results observed.

En variante selon la figure 2, l'acquisition et le traitement des données peut s'effectuer sur un ordinateur (14) au moyen d'un interface analogique digital (15) et d'un logiciel adapté. L'interface et le logiciel permettent alors de calculer et de visualiser les données suivantes en fonction du temps.
- la force de traction horizontale du sujet ou coureur
- la vitesse du tapis roulant
- le déplacement vertical du sujet ou coureur
- la puissance verticale instantanée fournie par le sujet ou coureur
- la puissance horizontale instantanée fournie par le sujet ou coureur
- la puissance totale instantanée fournie par le sujet ou coureur.
- la puissance verticale instantanée fournie (PV) est la conséquence des élévations et des abaissements successifs du coureur :
PV = M . g . Vv
ou M est la masse du sujet en kilogrammes
g est l'accélération de la pesanteur (9,81 m/s/s)
Vv est la vitesse verticale du sujet en m/s
- La puissance horizontale (Ph) instantanéefournie par le sujet est la conséquence de vitesse et des forces horizontales se produisant lors de la course.
Ph = Fh . Vh
où Fh est la force horizontale produite en Newton
Vh est la vitesse horizontale du sujet en m/s
- La puissance totale instantanée fournie (Pt) est la somme de la puissance horizontale instantanéefournie et de la puissance verticale instantanée fournie
Pt = Pv + Ph
Les graphiques des figures 3, 4 et 5 illustrent certaines mesures effectuées sur un sujet.As a variant according to FIG. 2, the data acquisition and processing can be carried out on a computer (14) by means of a digital analog interface (15) and suitable software. The interface and the software then make it possible to calculate and view the following data as a function of time.
- the horizontal pulling force of the subject or runner
- the speed of the treadmill
- the vertical displacement of the subject or runner
- the instantaneous vertical power provided by the subject or runner
- the instantaneous horizontal power supplied by the subject or runner
- the total instantaneous power supplied by the subject or runner.
- the instantaneous vertical power supplied (PV) is the consequence of the rider's successive increases and decreases:
PV = M. g. Vv
where M is the mass of the subject in kilograms
g is the acceleration of gravity (9.81 m / s / s)
Vv is the vertical speed of the subject in m / s
- The instantaneous horizontal power (Ph) provided by the subject is the consequence of speed and horizontal forces occurring during the race.
Ph = Fh. Vh
where Fh is the horizontal force produced in Newton
Vh is the horizontal speed of the subject in m / s
- The total instantaneous power supplied (Pt) is the sum of the instantaneous horizontal power supplied and the instantaneous vertical power supplied
Pt = Pv + Ph
The graphs in Figures 3, 4 and 5 illustrate some measurements made on a subject.

Selon une autre disposition caractéristique de l'invention, le tapis roulant est susceptible d'être entraîné à titre complémentaire par un moteur (16) dont le couple est constant de façon à compenser plus ou moins les forces de frottement mécanique, la vitesse du moteur étant libre. Le niveau du couple moteur est ajustable par un système d'asservissement en couple. Il y a lieu de noter que la valeur de compensation du couple moteur peut être établie pour une valeur proche de zéro compensant simplement les forces de frottement ou atteindre une valeur pouvant aller jusqu'à 2 ou 10 fois en augmentation ou en diminution de celles-ci.
- Ainsi lorsqu'il y a simple compensation des forces de frottement, on se trouve dans les mêmes conditions qu'une piste normale.
- Si le couple moteur est supérieur aux forces de frottement jusqu'à une valeur de 2 à 10 fois celles-­ ci, le sujet doit principalement retenir le tapis roulant assurant ainsi un entrainement du type excentrique permettant la survitesse.
- Si le couple moteur est inférieur aux forces de frottement jusqu'à une valeur de 2 à 10 fois celles-­ci, il y a alors augmentation de la dureté du tapis pour son entrainement, ayant pour conséquence un entrainement du type concentrique exigeant une surpuissance de l'utilisateur, c'est à dire un effort supérieur de ce dernier.According to another characteristic arrangement of the invention, the treadmill can be driven in a complementary manner by a motor (16) whose torque is constant so as to more or less compensate for the mechanical friction forces, the speed of the motor being free. The level of the engine torque is adjustable by a torque control system. It should be noted that the compensation value of the motor torque can be established for a value close to zero simply compensating for the friction forces or reaching a value which can go up to 2 or 10 times in increase or decrease of these. this.
- So when there is simple compensation of the friction forces, we are in the same conditions as a normal track.
- If the engine torque is greater than the friction forces up to a value of 2 to 10 times those Ci, the subject must mainly retain the treadmill thus ensuring an eccentric type of training allowing overspeed.
- If the engine torque is lower than the friction forces up to a value of 2 to 10 times these, then there is an increase in the hardness of the mat for its training, resulting in a concentric type of training requiring an overpower of the user, that is to say a greater effort of the latter.

Il apparait pour cette dernière situation d'une manière fort avantageuse que le tapis roulant ergométrique permet d'entrainer un sujet dans des conditions d'environnement supérieures à celles réelles existantes sur piste et donc d'obtenir à terme des résultats supérieurs et d'améliorer la vitesse ou la puissance maximum du sujet. Cela est particulièrement avantageux pour un entrainement de courses rapides du type sprints.It appears for this latter situation in a very advantageous way that the ergometric treadmill makes it possible to train a subject in environmental conditions superior to those existing on the track and therefore to obtain superior results in the long term and to improve the maximum speed or power of the subject. This is particularly advantageous for training fast races like sprints.

La modulation du couple moteur et son action sur le tapis roulant est obtenu par des moyens mécaniques classiques, à la portée de l'homme de l'art.The modulation of the motor torque and its action on the treadmill is obtained by conventional mechanical means, within the reach of those skilled in the art.

L'invention trouve de nombreux avantages. Le tapis roulant ergométrique permet de faire varier et à volonté la vitesse, les forces et les puissances fournies lors de la course. Il offre des possibilités de mesures et d'analyses bio-mécaniques impossibles à obtenir sur les tapis roulants classiques.The invention finds many advantages. The ergometric treadmill allows you to vary the speed, forces and powers supplied during the race at will. It offers possibilities of bio-mechanical measurements and analyzes impossible to obtain on conventional treadmills.

Il offre de nouvelles perspectives d'entrainement et de recherche. En particulier, un entrainement à la course, avec possibilité de variation de la puissance de course, est possible.It offers new perspectives for training and research.
