Abstract

L’invention décrit une manivelle réglable qui s’applique aux treuils, bicyclettes, vélos d’appartement, équipements de sport, de rééducation et autres. Le dispositif comprend : - Support (10) - Arbre tournant (20) - Bras d’entrainement (30) fixé à l’arbre (20) - Récepteur du mouvement (40) fixé à l’arbre (20) - Manivelle (50) avec sa poignée (60) - Biellette de liaison (70) reliant le bras (30) à la manivelle (50) - Bague excentrée interne (80) fixée au support (10) - Bague excentrée externe (90) fixée à la bague (80) Le choix de l’orientation des bagues excentrées (80) et (90) permet de régler la position (distance-orientation) de l’axe de la manivelle (50) Le réglage des bagues excentrées est effectué à l’arrêt et pendant la rotation. Ce dispositif est installé sur un pédalier à plusieurs manivelles. Le réglage des bagues internes et externes permet de positionner (distance-orientation) chacun des axes des manivelles. Figure pour l’abrégé : figure 1The invention describes an adjustable crank which is applicable to winches, bicycles, exercise bikes, sports equipment, rehabilitation equipment and others. The device comprises: - Support (10) - Rotating shaft (20) - Drive arm (30) fixed to the shaft (20) - Movement receiver (40) fixed to the shaft (20) - Crank (50) ) with its handle (60) - Connecting rod (70) connecting the arm (30) to the crank (50) - Internal eccentric ring (80) fixed to the support (10) - External eccentric ring (90) fixed to the ring (80) The choice of the orientation of the eccentric rings (80) and (90) makes it possible to adjust the position (distance-orientation) of the crank axis (50) The adjustment of the eccentric rings is carried out when stopped and during rotation. This device is installed on a crankset with several cranks. Adjusting the internal and external rings allows you to position (distance-orientation) each of the crank axes.
