  • the up-and-down motion sleeve handle structure 56 Directly or indirectly disposed above the up and down motion sleeve structure 55
  • the up and down motion sleeve resistance-damping structure may be a straight rod or equal center directly attached to the upper structures 38, 39 of the left and right manual swing arms
  • a spring structure 57 over the associated structural portion of the curved rod or other corresponding suitable structure (as is the case shown in Figure 29).

Abstract

L'invention concerne un équipement sportif comportant des manivelles gauche et droite (1, 2) et des structures de mouvement conjoint associées entraînées en parallèle ou en alternance. Grâce au système de structure de renvoi de manivelle fourni sous la forme d'un câble, d'une came excentrique, d'un palier excentrique, d'un arbre-manivelle ou d'autres formes appropriées et/ou d'un mécanisme de variation d'angle de manivelle correspondant (123), des manivelles gauche et droite (1, 2), des pédales sportives elliptiques (circonférentielles) gauche et droite (90) entraînées par celles-ci, et/ou des structures de bras oscillant manuel gauche et droit (91) d'un équipement sportif associé, sont entraînées en parallèle ou en alternance, et les pédales sportives elliptiques (circonférentielles) gauche et droite (90) etc., qui sont parallèles l'une à l'autre, sont facilement démarrées et mieux entraînées à 360 degrés, de telle sorte que l'équipement sportif correspondant, tel qu'un vélo d'appartement, un vélo elliptique, un cheval mécanique, un rameur ou un vélo, et des produits d'équipement sportif mixtes qui peuvent être facilement obtenus, peuvent être utilisés de manière plus complète et optimale, et présenter une valeur marchande plus élevée.
