The treadmill is the most common machine, it is intended to provide a place where a user can practice walking, jogging or indoor race.

Lorsqu'un utilisateur court ou marche sur le tapis de course, chaque pas provoque une force de réaction dans les articulations du genou et de la cheville. Un utilisateur peut facilement subir des lésions des muscles et du squelette en courant ou en marchant longtemps sur le tapis de course. Certains nouveaux tapis de course sont munis d'un dispositif d'amortissement en vue de réduire la charge appliquée aux articulations des genoux et aux articulations des chevilles, lorsqu'un utilisateur court ou marche sur le tapis de course. Il a existé un tapis de course équipé d'un dispositif d'amortissement entre le plateau et la base. Le dispositif d'amortissement peut être un ressort, ou un amortisseur hydraulique, destiné à absorber les vibrations quand un utilisateur court ou marche sur le tapis de course. Cette invention était divulguée dans le brevet U.S. N 5 072 928 délivré au nom de Stearn et al. et le brevet U.S. N 6 872 168 délivré au nom de Wang et al. Le brevet U.S. N 5 441 468 délivré au nom de Deckers et ale. a fait connaître un tapis de course comportant des tampons amortisseurs sous la bande en déplacement, destinés à absorber les vibrations. Des inventions similaires comprennent l'invention de Buhler (brevet U.S. N 5 542 892) et l'invention de Chiu (brevet U.S. Na 6 117 053). D'autres dispositifs d'amortissement pour tapis de course ressortent de l'invention de Eschenbach (brevet U.S. N 6 053 848) qui prévoit une corde en tant que moyen d'amortissement, et de l'invention délivrée à Dalebout et al. (brevet U.S.  When a user runs or walks on the treadmill, each step causes a reaction force in the knee and ankle joints. A user can easily experience muscle and skeletal injury by running or walking for a long time on the treadmill. Some new treadmills have a cushioning device to reduce the load on the knee joints and ankle joints when a user is running or walking on the treadmill. There was a treadmill equipped with a cushioning device between the tray and the base. The damping device may be a spring, or hydraulic damper, for absorbing vibrations when a user is running or walking on the treadmill. This invention was disclosed in U.S. Patent No. 5,072,928 issued to Stearn et al. and U.S. Patent No. 6,872,168 issued to Wang et al. U.S. Patent No. 5,441,468 issued to Deckers et al. has introduced a treadmill with damping pads under the moving band for absorbing vibrations. Similar inventions include the Buhler invention (U.S. Patent No. 5,542,892) and the invention of Chiu (U.S. Patent No. 6,117,053). Other cushioning devices for treadmills emerge from the invention of Eschenbach (U.S. Patent No. 6,053,848) which provides a cord as a damping means, and of the invention delivered to Dalebout et al. (U.S. Patent

N 6 821 230) qui prévoit un bloc d'amortissement comportant des trous, les dimensions des trous étant différentes, de telle manière que le bloc est tourné pour obtenir des capacités d'amortissement différentes. Les dispositifs d'amortissement ci-dessus n'absorbent que les vibrations normales au dispositif d'amortissement. La capacité d'amortissement est médiocre en ce qui concerne les vibrations qui ne sont pas normales au dispositif d'amortissement. Dans le cas d'un dispositif d'amortissement à ressort, la vibration non normale à l'axe du ressort provoque une force de cisaillement telle que le ressort a une faible capacité de l'absorber et la force de cisaillement peut endommager le ressort. L'objectif premier de la présente invention est de proposer un dispositif d'amortissement d'appareil d'exercice qui peut absorber les vibrations provenant de directions variées. Selon l'objectif de la présente invention, un dispositif d'amortissement qui est monté sur une machine d'exercice en vue d'absorber les vibrations comprend un dispositif de liaison comportant un pivot d'extrémité situé sur la base de la machine d'exercice et un élément élastique comportant des extrémités opposées qui poussent respectivement la machine d'exercice et le dispositif de liaison. L'angle entre le dispositif de liaison et le sol est inférieur à quatre-vingt-dix degrés, de telle manière que les vibrations provenant de directions différentes sont transmises au dispositif de liaison et le font osciller et que l'élément élastique est déformé élastiquement en vue d'absorber les vibrations. La figure 1 est une vue en perspective du tapis de course d'une forme de réalisation préférée de la présente invention ; la figure 2 est une vue éclatée du dispositif d'amortissement de la forme de réalisation préférée de la présente invention ; la figure 3 est une vue en coupe du dispositif d'amortissement de la forme de réalisation préférée de la présente invention, montrant l'état non chargé ; et la figure 4 est une vue en coupe du dispositif d'amortissement de la forme de réalisation préférée de la présente invention, représentant l'état chargé. Comme représenté sur la figure 1 et sur la figure 2, un tapis de course 1 de la forme de réalisation préférée de la présente invention comprend une base 10 et un plateau 12 dont l'extrémité avant est connectée à la base, sur lequel sont montés une bande en mouvement 14 et deux dispositifs d'amortissement 18 (dont un seul est représenté sur les dessins). Chacun des dispositifs d'amortissement 18 comporte un dispositif de liaison 20, une roue 22, un élément élastique 24, qui est un ressort dans la forme de réalisation, et une monture 26. Le dispositif de liaison 20 comporte deux bras parallèles 28 et une plaque 30 fixée aux bras 28. La plaque 30 comporte un alésage 32 entre les bras 28. Les bras 28 ont des extrémités intérieures qui sont montées à pivotement sur le fond du plateau 12 et des extrémités extérieures qui sont montées à pivotement avec la roue 22.  No. 6,821,230) which provides a damping block with holes, the dimensions of the holes being different, so that the block is rotated to obtain different damping capacities. The above damping devices only absorb vibrations normal to the damping device. The damping capacity is mediocre with regard to the vibrations which are not normal to the damping device. In the case of a spring damping device, the non-normal vibration at the spring axis causes a shearing force such that the spring has a low capacity to absorb it and the shearing force can damage the spring. The primary objective of the present invention is to provide an exercise apparatus damping device which can absorb vibrations from various directions. According to the object of the present invention, a damping device which is mounted on an exercise machine for absorbing vibrations comprises a connecting device having an end pivot located on the base of the machine. exercise and an elastic member having opposite ends which respectively push the exercise machine and the connecting device. The angle between the connecting device and the ground is less than ninety degrees, so that vibrations from different directions are transmitted to the connecting device and oscillate and the elastic member is elastically deformed. to absorb the vibrations. Fig. 1 is a perspective view of the treadmill of a preferred embodiment of the present invention; Fig. 2 is an exploded view of the damping device of the preferred embodiment of the present invention; Fig. 3 is a sectional view of the damping device of the preferred embodiment of the present invention showing the unfilled state; and Fig. 4 is a sectional view of the damping device of the preferred embodiment of the present invention showing the charged state. As shown in FIG. 1 and FIG. 2, a treadmill 1 of the preferred embodiment of the present invention comprises a base 10 and a tray 12 whose front end is connected to the base, on which are mounted a moving band 14 and two damping devices 18 (only one of which is shown in the drawings). Each of the damping devices 18 comprises a connecting device 20, a wheel 22, an elastic element 24, which is a spring in the embodiment, and a mount 26. The connecting device 20 comprises two parallel arms 28 and a plate 30 attached to the arms 28. The plate 30 has a bore 32 between the arms 28. The arms 28 have inner ends which are pivotally mounted on the bottom of the plate 12 and outer ends which are pivotally mounted with the wheel 22 .

La roue 22 est en appui sur le sol pour rouler. La monture 26 est fixée au fond du plateau 12 au moyen d'une tige 34 qui passe dans l'alésage 32 de la plaque 30 du dispositif de liaison 20. Un écrou 36 est vissé à l'extrémité distale de la tige 34 et contre la plaque 30. Le ressort 24 est enfilé sur la tige 34, ses extrémités opposées poussant respectivement sur la monture 26 et respectivement sur la plaque 30 du dispositif de liaison 20. Comme représenté sur la figure 3, lorsqu'un utilisateur (non représenté) court ou marche sur la bande en mouvement 14 du tapis de course de la présente invention, les pas provoquent des vibrations provenant de directions variées et celles-ci se transmettent aux dispositifs de liaison 20 des dispositifs d'amortissement 18. Selon une analyse mécanique, la force de vibration provenant de chaque direction par rapport au dispositif de liaison 20 peut se décomposer sur une composante normale (Fn) et une composante horizontale (Fs). La composante normale (Fn) fera osciller le dispositif de liaison 20 et comprimera le ressort 24, comme représenté sur la figure 3. Lorsque la vibration cesse, le ressort 24 ramène de force les dispositifs d'amortissement 20 à la position initiale, comme représenté sur la figure 2. Le rapport de la composante normale (Fn) et à composante horizontale (Fs) est fonction d'un angle e entre le dispositif de liaison 20 et le sol. Lorsque la valeur de la composante normale (Fn) est positive par rapport à l'angle O. La présente invention recommande que l'angle e soit inférieur à 45 degrés, et de préférence, que l'angle e soit compris entre 25 degrés et 35 degrés. Lors du fonctionnement l'écrou 36 peut être vissé pour régler la pré-compression du ressort 24. La figure 3 représente le ressort 24 dans un état de moindre pré- compression, qui procure au dispositif d'amortissement 18 une capacité d'amortissement "douce". L'écrou 36 peut être vissé de manière à comprimer fortement le ressort 24. Le dispositif d'amortissement 18 peut procurer une capacité d'amortissement "dure".  The wheel 22 is resting on the ground to roll. The mount 26 is fixed to the bottom of the plate 12 by means of a rod 34 which passes into the bore 32 of the plate 30 of the connecting device 20. A nut 36 is screwed to the distal end of the rod 34 and against the plate 30. The spring 24 is threaded on the rod 34, its opposite ends respectively pushing on the mount 26 and respectively on the plate 30 of the connecting device 20. As shown in Figure 3, when a user (not shown) When walking or walking on the moving belt 14 of the treadmill of the present invention, the steps cause vibrations from various directions and these are transmitted to the connecting devices 20 of the damping devices 18. According to a mechanical analysis, the vibration force from each direction relative to the connecting device 20 can decompose on a normal component (Fn) and a horizontal component (Fs). The normal component (Fn) will oscillate the connecting device 20 and compress the spring 24, as shown in Figure 3. When the vibration ceases, the spring 24 forcibly returns the damping devices 20 to the initial position, as shown in Figure 2. The ratio of the normal component (Fn) and horizontal component (Fs) is a function of an angle e between the connecting device 20 and the ground. When the value of the normal component (Fn) is positive with respect to the angle O. The present invention recommends that the angle e be less than 45 degrees, and preferably, that the angle e is between 25 degrees and 35 degrees. In operation the nut 36 can be screwed to adjust the pre-compression of the spring 24. FIG. 3 shows the spring 24 in a state of less pre-compression, which provides the damping device 18 with a damping capacity. sweet. " The nut 36 can be screwed so as to strongly compress the spring 24. The damping device 18 can provide a "hard" damping capacity.
