A hand exerciser device for fatigueless muscular exercising of a user's hand, arm and wrist, comprising: a first and a second spherical ball, each sized to fit inside the palm of a user's hand and surfaced for comfortable skin contact. A rigid connector tube interconnects the first and second balls by having its opposite end portions slidingly extending through a bore in the wall of each corresponding ball, wherein free rotational motion of the first and second ball members independently of one another is achieved. The intermediate section of the connector tube forms an accordion pleating, providing limited universal joint capability.
Cette invention concerne un accessoire d'exercice pour la mobilisation sans fatigue musculaire de la main, du poignet et de l'avant-bras de l'utilisateur. Il comprend une première et une seconde boules dimensionnées pour se loger au creux de la main et présentant une surface confortable au toucher. Un tube connecteur rigide relie les deux boules; elles y sont montées en ajustement glissant et de manière à pouvoir tourner librement l'une rapport à l'autre. La section médiane du connecteur prend la forme d'un soufflet autorisant une articulation limitée dans tous les sens.
