Description

PLATE-FORME D'ENTRAINEMENT A USAGE SPORTIF ET/OU REEDUCATIF TRAINING PLATFORM FOR SPORTS AND / OR REHABILITATION USE
L'invention se rattache au secteur technique des moyens d'entraînement et/ou de rééducation du type tapis roulant.The invention relates to the technical sector of training and / or rehabilitation means of the treadmill type.
Il existe de nombreux types de tapis roulants, pour des applications diverses.There are many types of treadmills for a variety of applications.
Pour l'essentiel, un tapis roulant comprend une bande sans fin montée entre deux rouleaux entraînés positivement en rotation à vitesse constante ou variable. L'ensemble de la bande et des rouleaux est monté dans un châssis support équipé d'agencements de soutien de la bande. A partir de cette conception de base, différentes solutions ont été proposées en fonction des applications envisagées.Essentially, a treadmill includes an endless belt mounted between two rollers positively driven in rotation at constant or variable speed. The assembly of the strip and the rollers is mounted in a support frame equipped with support arrangements for the strip. From this basic design, different solutions have been proposed depending on the applications envisaged.
Par exemple, dans une version simplifiée, le tapis a seulement une position horizontale, tandis que dans une autre version, le tapis est monté avec capacité d'inclinaison. Quelles que soient les formes de réalisation, ces tapis roulants sont généralement de dimensions relativement réduites et ne peuvent être utilisés que par une personne ou éventuellement plusieurs personnes disposées sensiblement selon un même alignement. Autrement dit, la surface utile du tapis est limitée en dimensions, notamment en largeur, ce qui limite son utilisation à des exercices qui doivent être effectués essentiellement en ligne.For example, in a simplified version, the mat has only a horizontal position, while in another version, the mat is mounted with tilting capacity. Whatever the embodiments, these treadmills are generally of relatively small dimensions and can only be used by one person or possibly several people arranged substantially in the same alignment. In other words, the useful surface of the mat is limited in size, in particular in width, which limits its use to exercises which must be carried out essentially online.
A partir de cette conception de base, le problème que se propose de résoudre l'invention est de pouvoir réaliser un tapis roulant de dimensions très supérieures à ce qui existe actuellement sur le marché, par exemple 4 mètres de long sur 3 mètres de large environ, avec la possibilité d'atteindre des vitesses d'entraînement relativement élevées jusqu'à 60 kilomètres/heure par exemple environ.From this basic design, the problem which the invention proposes to solve is to be able to produce a treadmill of dimensions much greater than what currently exists on the market, for example 4 meters long by 3 meters wide approximately, with the possibility of reaching relatively high drive speeds up to 60 km / hour for example approximately.
Bien évidemment, de telles caractéristiques dimensionnelles et de vitesse posent un réel problème, notamment au niveau de la stabilité de la bande et des vibrations. Un problème important apparaît également au niveau de la sécurité des utilisateurs.Obviously, such dimensional and speed characteristics pose a real problem, in particular as regards the stability of the strip and the vibrations. There is also a significant problem with user security.
Pour atteindre ces différents objectifs, il a été conçu et mis au point une plate-forme d'entraînement à usage sportif et/ou rééducatif équipée d'un tapis roulant sous forme d'une bande sans fin assujettie à au moins deux rouleaux dont l'un au moins est motorisé, l'ensemble de la bande et des rouleaux étant montés dans un châssis support, remarquable en ce que : - le châssis est articulé à l'une de ses extrémités sur une structure fixe présentant des moyens aptes à assurer l'inclinaison, d'une manière contrôlée, dudit châssis, sans déborder du plan défini par la bande quelle soit la position du châssis ; - le châssis présente, du côté de son articulation, des moyens de protection aptes à faire office de surface d'appui et de retenue du ou des utilisateurs, quelle que soit la position dudit châssis.To achieve these various objectives, a training platform for sports and / or rehabilitative use has been designed and developed, equipped with a treadmill in the form of an endless band subject to at least two rollers, including the at least one is motorized, the whole of the strip and the rollers being mounted in a support frame, remarkable in that: - the frame is articulated at one of its ends on a fixed structure having means capable of ensuring the inclination, in a controlled manner, of said chassis, without going beyond the plane defined by the strip, whatever the position of the chassis; - The chassis has, on the side of its articulation, protective means capable of acting as a support and retaining surface for the user or users, whatever the position of said chassis.
Selon l'invention, le châssis est de dimensions très supérieures à celles des tapis existant actuellement sur le marché, ce qui permet une utilisation par plusieurs personnes à la fois et la possibilité de faire des exercices très variés compte tenu de la grande surface de travail. Pour résoudre le problème posé d'assurer l'inclinaison, d'une manière contrôlée du châssis, sans que les organes ne dépassent de la hauteur du plan, les moyens d'inclinaison du châssis sont constitués par des vis sans fin motorisée montées de part et d'autre du châssis, en position de coopération avec des paliers taraudés solidaires de la base du châssis, les moyens d'entraînement desdites vis étant logés dans un carter articulé à la partie basse de la structure par des organes du type rotules pour rabaisser l'ensemble desdits moyens d'inclinaison.According to the invention, the frame is of dimensions much larger than those of the carpets currently existing on the market, which allows use by several people at the same time and the possibility of doing very varied exercises taking into account the large work surface. . To solve the problem posed of ensuring the inclination, in a controlled manner of the chassis, without the members exceeding the height of the plane, the means of inclination of the chassis are constituted by motorized endless screws mounted on one side and on the other side of the chassis, in the position of cooperation with threaded bearings integral with the base of the chassis, the means for driving said screws being housed in a casing articulated at the lower part of the structure by members of the ball-joint type for lowering all of said tilting means.
Pour résoudre le problème posé de rabaisser au maximum l'équipement d'inclinaison, les organes du type rotules sont constitués par une partie hémisphérique solidaire du carter recevant les moyens d'entraînement des vis, et coopérant avec un berceau de forme complémentaire solidaire de la structure fixe.To resolve the problem posed of lowering the tilting equipment as much as possible, the ball-and-socket type members consist of a hemispherical part secured to the casing receiving the drive means of the screws, and cooperating with a cradle of complementary shape secured to the fixed structure.
Pour résoudre le problème posé d'assurer la sécurité du ou des utilisateurs, notamment en position inclinée de l'ensemble du châssis, en évitant de tomber dans le vide ou contre un obstacle, les moyens de protection sont constitués par une plaque de largeur correspondant sensiblement à celle du châssis, ladite plaque présentant, à l'une de ses extrémités, des éléments d'accouplement, d'une manière articulée, de part et d'autre du rouleau d'entraînement correspondant de la bande, l'autre extrémité de la plaque présentant des organes d'appui et de roulement par rapport à une zone où est installé l'ensemble.To resolve the problem posed of ensuring the safety of the user (s), in particular in the inclined position of the entire chassis, by avoiding falling into a vacuum or against an obstacle, the protection means are constituted by a plate of corresponding width substantially to that of the chassis, said plate having, at one of its ends, coupling elements, in an articulated manner, on either side of the corresponding drive roller of the strip, the other end of the plate having supporting and rolling members with respect to an area where the assembly is installed.
Compte tenu du problème posé de réaliser une plate-forme de grandes dimensions, la structure fixe est logée dans une fosse, les organes d'appui et de roulement de la plaque de protection coopérant avec un élément support logé dans la dite fosse et de hauteur déterminée pour assurer un positionnement de la plaque dans le prolongement de la bande et sensiblement dans le même plan, en position horizontale de cette dernière.Given the problem posed of making a large platform, the fixed structure is housed in a pit, the organs of support and rolling of the protective plate cooperating with a support element housed in said pit and of determined height to ensure positioning of the plate in the extension of the strip and substantially in the same plane, in the horizontal position of this last.
A partir de ce concept de base, la largeur du châssis est très sensiblement égale ou très légèrement inférieure à sa longueur.From this basic concept, the width of the chassis is very substantially equal to or very slightly less than its length.
Avantageusement, la largeur du châssis est d'environ 3 m, tandis que sa longueur est d'environ 4m.Advantageously, the width of the chassis is approximately 3 m, while its length is approximately 4 m.
Bien évidemment, les différents organes de commande et de transmission de la bande sans fin sont dûment sélectionnés pour assurer une parfaite stabilité de cette dernière, en évitant au maximum les vibrations, si l'on considère les caractéristiques dimensionnelles recherchées supérieures au-delà de ce qui a été généralement admis.Obviously, the different control and transmission members of the endless belt are duly selected to ensure perfect stability of the latter, avoiding vibrations as much as possible, if we consider the dimensional characteristics sought above and beyond this. which was generally accepted.
L'invention est exposée ci-après plus en détail à l'aide des figures des dessins annexés dans lesquels : - la figure 1 est une vue en perspective de la plate-forme selon l'invention à caractère schématique pour illustrer ses caractéristiques dimensionnelles avec un nombre important d'utilisateurs ;The invention is set out below in more detail with the aid of the figures of the appended drawings in which: - Figure 1 is a perspective view of the platform according to the invention of schematic nature to illustrate its dimensional characteristics with a large number of users;

- la figure 4 est une vue en plan correspondant à la figure 2 ; - la figure 5 est une vue en coupe transversale considérée selon la ligne 5-5 de la figure 4 ;- Figure 4 is a plan view corresponding to Figure 2; - Figure 5 is a cross-sectional view taken along line 5-5 of Figure 4;
- la figure 6 est une vue partielle à une échelle plus importante des moyens d'inclinaison du châssis.- Figure 6 is a partial view on a larger scale of the chassis tilt means.
La plate-forme d'entraînement désignée dans son ensemble par (P) comprend un tapis roulant sous forme d'une bande sans fin (1), assujettie à au moins deux rouleaux d'entraînement (2) et (3). L'un des rouleaux au moins, par exemple le rouleau (2) est motorisé en étant accouplé à un moteur (M) asservi à une électronique de commande, de tout type connu et approprié, pour entraîner la bande (1) selon une vitesse linéaire constante ou variable à volonté. L'ensemble de la bande (1) et des rouleaux d'entraînement (2) et (3) est monté dans un châssis (4) agencé pour assurer le support de la bande (1). Comme indiqué, le problème que se propose de résoudre l'invention est de réaliser une plate-forme d'entraînement de grandes dimensions et, à tout le moins, de dimensions très supérieures à celles généralement admises pour ce type d'équipement.The drive platform designated as a whole by (P) comprises a conveyor belt in the form of an endless belt (1), secured to at least two drive rollers (2) and (3). At least one of the rollers, for example the roller (2) is motorized by being coupled to a motor (M) controlled by control electronics, of any known and appropriate type, for driving the strip (1) at a speed constant or variable linear at will. The assembly of the strip (1) and the drive rollers (2) and (3) is mounted in a chassis (4) arranged to support the strip (1). As indicated, the problem which the invention proposes to solve is to produce a training platform of large dimensions and, at the very least, of dimensions much greater than those generally accepted for this type of equipment.
Comme le montre notamment la figure 4, la largeur du châssis est très sensiblement égale ou très légèrement inférieure à sa longueur. Le châssis constitue une ossature fermée composée de deux côtés latéraux (4a) et deux côtés transversaux (4b) réalisés, par exemple, à partir de fers profilés du type IPN, afin d'assurer une très grande rigidité à l'ensemble. A titre indicatif, les côtés latéraux (4a) du châssis (4) ont une longueur d'environ 4 mètres, tandis que ses côtés transversaux (4b) ont une longueur d'environ 3 mètres. Compte tenu de l'importance de ces dimensions, pour assurer la meilleure stabilité possible à la bande (1), en réduisant au maximum les vibrations, les rouleaux d'entraînement (2) et (3) sont sélectionnés pour être de haute précision du type conique, et entraînés par un moteur (M) de puissance suffisante pour éviter l'emploi de lubrifiant afin d'augmenter l'adhérence entre la bande et les rouleaux, permettant d'obtenir une parfaite stabilité de ladite bande. Cette forte adhérence assure un effort de recentrage important.As shown in particular in Figure 4, the width of the frame is very substantially equal to or very slightly less than its length. The chassis constitutes a closed framework composed of two lateral sides (4a) and two transverse sides (4b) produced, for example, from profiled irons of the IPN type, in order to ensure very high rigidity in the assembly. As an indication, the lateral sides (4a) of the chassis (4) have a length of approximately 4 meters, while its transverse sides (4b) have a length of approximately 3 meters. Given the importance of these dimensions, to ensure the best possible stability to the strip (1), by reducing vibrations as much as possible, the drive rollers (2) and (3) are selected to be of high precision of the conical type, and driven by a motor (M) of sufficient power to avoid the use of lubricant in order to increase the adhesion between the strip and the rollers, making it possible to obtain perfect stability of said strip. This strong adhesion ensures a significant refocusing effort.
Le châssis (4) est articulé, à l'une de ses extrémités, sur une structure fixe (5) équipée de moyens aptes à assurer l'inclinaison, d'une manière contrôlée, dudit châssis sans que les moyens d'inclinaison débordent du plan défini par la bande (1) et ce, quelle que soit la position du châssis, comme il sera indiqué dans la suite de la description. Par exemple, les côtés latéraux (4a) du châssis (4) sont accouplés d'une manière articulée par un axe (6) entre deux bras supports verticaux (7) solidaires des longerons (5a) de la structure fixe (5). A noter que les longerons (5a) de la structure (5) peuvent être entretoisés par différents longerons pour assurer une rigidité suffisante.The chassis (4) is articulated, at one of its ends, on a fixed structure (5) equipped with means capable of ensuring the inclination, in a controlled manner, of said chassis without the inclination means overflowing from the plane defined by the strip (1), regardless of the position of the chassis, as will be indicated in the following description. For example, the lateral sides (4a) of the chassis (4) are coupled in an articulated manner by an axis (6) between two vertical support arms (7) integral with the side members (5a) of the fixed structure (5). Note that the beams (5a) of the structure (5) can be braced by different beams to ensure sufficient rigidity.
Les moyens d'inclinaison contrôlés de l'ensemble du châssis (4) sont constitués par des vis sans fin parallèles (8) et (9) disposées selon le même alignement. Ces vis (8) et (9) sont engagées dans des paliers taraudés (10) et (11) portés par des éléments supports (12) et (13) solidaires des côtés latéraux (4a) du châssis (4).The controlled tilting means of the entire chassis (4) are constituted by parallel endless screws (8) and (9) arranged in the same alignment. These screws (8) and (9) are engaged in threaded bearings (10) and (11) carried by support elements (12) and (13) integral with the lateral sides (4a) of the chassis (4).
L'entraînement en rotation des vis sans fin (8) et (9) s'effectue par un moteur commun central (14) et deux arbres de commande disposés en alignement (15) et (16) et dont les extrémités libres sont accouplées à des organes d'entraînement du type pignons coopérant avec des organes complémentaires montés en bout de chacune des vis sans fin (8) et (9). Par exemple, l'entraînement en rotation des vis (8) et (9) par les arbres (15) et (16) peut être effectué par des couples de pignons coniques disposés dans deux plans orthogonaux, sans exclure d'autres moyens.The worm (8) and (9) are driven in rotation by a central common motor (14) and two control shafts arranged in alignment (15) and (16) and whose free ends are coupled to pinion type drive members cooperating with complementary members mounted at the end of each of the worms (8) and (9). For example, the driving in rotation of the screws (8) and (9) by the shafts (15) and (16) can be carried out by pairs of bevel gears arranged in two orthogonal planes, without excluding other means.
Les organes d'entraînement sont intégrés dans des carters (17) et (18) montés avec capacité d'articulation à une partie de la structure fixe (5), notamment au niveau de ses longerons latéraux (5a).The drive members are integrated in housings (17) and (18) mounted with capacity for articulation to a part of the fixed structure (5), in particular at the level of its lateral beams (5a).
Pour résoudre le problème d'éviter aux vis sans fin (8) et (9) de déborder du plan défini par le tapis roulant (T) en position horizontale, et ce quelle que soit l'inclinaison du châssis, il est apparu nécessaire de rabaisser au maximum l'articulation des vis (8) et (9) par rapport à la structure (5). Dans ce but, les carters (17) et (18) sont articulés à la structure fixe (5) par des organes du type rotules. Les organes du type rotules sont constitués par une partie hémisphérique (19-20) solidaire du carter (17-18) et coopérant avec un berceau (26-27) de forme complémentaire et solidaire de la structure fixe (5), notamment d'une partie de chacun des longerons (5a).To solve the problem of avoiding the worms (8) and (9) overflowing the plane defined by the conveyor belt (T) in a horizontal position, regardless of the inclination of the chassis, it appeared necessary to lower the articulation of the screws (8) and (9) as much as possible relative to the structure (5). For this purpose, the casings (17) and (18) are articulated to the fixed structure (5) by members of the ball-joint type. The organs of the ball-joint type consist of a hemispherical part (19-20) integral with the casing (17-18) and cooperating with a cradle (26-27) of complementary shape and integral with the fixed structure (5), in particular of part of each of the side members (5a).
Compte tenu des caractéristiques dimensionnelles de l'ensemble de la plate-forme d'entraînement, la structure fixe (5) est logée dans une fosse (F) convenablement dimensionnée en profondeur, de sorte qu'en position horizontale du tapis roulant, la bande (1) affleure très sensiblement le plan horizontal défini par la surface délimitant ladite fosse (F). Un autre problème important que se propose de résoudre l'invention est d'assurer une parfaite sécurité aux utilisateurs, si l'on considère, d'une part, les dimensions importantes de la plate-foπne et, d'autre part, la vitesse à laquelle peut être entraînée linéairement la bande (1) de l'ordre de 60 kilomètres/heure. Notamment, il est apparu important d'équiper le châssis (4), du côté de son articulation (10), de moyens de protection aptes à faire office de surface d'appui et de retenue du ou des utilisateurs, quelle que soit la position du châssis, en considérant que l'entraînement de la bande (1) conjugué à l'inclinaison, a tendance à éjecter vers l'extérieur l'utilisateur.Taking into account the dimensional characteristics of the entire drive platform, the fixed structure (5) is housed in a pit (F) suitably dimensioned in depth, so that in the horizontal position of the treadmill, the strip (1) very substantially flush with the horizontal plane defined by the surface delimiting said pit (F). Another important problem which the invention proposes to solve is to ensure perfect security for users, if one considers, on the one hand, the large dimensions of the platform and, on the other hand, the speed to which can be linearly driven the strip (1) of the order of 60 km / hour. In particular, it appeared important to equip the chassis (4), on the side of its articulation (10), with protective means capable of acting as a support and retaining surface for the user or users, whatever the position. of the chassis, considering that the drive of the strip (1) combined with the inclination, tends to eject the user outwards.
Les moyens de protection sont constituées par une plaque (21) dont la largeur correspond sensiblement à la largeur du châssis (4). Cette plaque (21) présente, à l'une de ses extrémités, des flasques latéraux (22) conformés pour permettre son accouplement, d'une manière articulée, de part et d'autre du rouleau d'entraînement motorisé (2). A l'autre extrémité, la plaque (21) reçoit un ou des organes d'appui et de roulement (23) avec des surfaces d'appui que présente la fosse. Par exemple, les organes d'appui et de roulement (23) coopèrent avec un portique (24) situé à l'intérieur de la fosse, à proximité de l'un de ses bords transversaux. Compte tenu de ces dispositions, il apparaît donc que la plaque (21) obture constamment l'espace entre l'extrémité de la bande (1) et le bord de la fosse (F) et ce quelle que soit l'inclinaison de l'ensemble du tapis.The protection means consist of a plate (21) whose width corresponds substantially to the width of the chassis (4). This plate (21) has, at one of its ends, lateral flanges (22) shaped to allow its coupling, in an articulated manner, on either side of the motorized drive roller (2). At the other end, the plate (21) receives one or more bearing and rolling members (23) with bearing surfaces presented by the pit. For example, the bearing and rolling members (23) cooperate with a gantry (24) located inside the pit, near one of its transverse edges. In view of these provisions, it therefore appears that the plate (21) constantly closes the space between the end of the strip (1) and the edge of the pit (F), whatever the inclination of the whole carpet.
Bien évidemment, l'ensemble du châssis (4) peut être équipé, au niveau notamment de ses bords latéraux, de garde-corps (25). Les avantages ressortent bien de la description, en particulier on souligne et on rappelle :Obviously, the entire chassis (4) can be equipped, particularly at its lateral edges, with railings (25). The advantages clearly emerge from the description, in particular it is emphasized and recalled:
- les dimensions importantes du tapis roulant qui constitue une véritable plate-forme d'entraînement à usage sportif et/ou rééducatif ;- the large dimensions of the treadmill, which constitutes a real training platform for sports and / or rehabilitation use;
- la vitesse de défilement importante de la bande et cela en toute sécurité pour le ou les utilisateurs, avec une parfaite stabilité de la bande, sans vibration particulière. - the high running speed of the strip and this in complete safety for the user or users, with perfect stability of the strip, without any particular vibration.
