Abstract

L'invention concerne une barre horizontale d'exercice physique comprenant une partie corps principal (1), des trous traversants étant formés à deux extrémités de la partie corps principal (1). Des tiges télescopiques (2) sont insérées, au niveau de deux côtés, dans les trous traversants et peuvent se déplacer axialement le long des trous traversants. Les tiges télescopiques (2) des deux côtés sont parallèles. Les tiges télescopiques (2) et la partie corps principal (1) sont limitées en rotation. Des parties de contact (6) sont disposées aux deux extrémités des tiges télescopiques (2). Une partie dent principale et une tige de vis (9) sont disposées dans la partie corps principal (1). La partie dent principale est reliée à une partie de réglage (15), tandis que la partie corps principal (1) présente en surface un trou fendu (14). La partie de réglage (15) est exposée à partir du trou fendu (14). La tige de vis (9) est parallèle aux tiges télescopiques (2). Les tiges télescopiques (2) présentent en surface des parties filetées de liaison. La tige de vis (9) est en liaison par filetage avec les parties filetées de liaison et la tige de vis (9) est reliée à une partie dent entraînée. Enfin la partie dent entraînée et la partie dent principale sont dans une transmission rotative à un ou à plusieurs étages. Le réglage de la barre horizontale d'exercice physique est stable et économise des manipulations. Il a un effet auto-verrouillant dans des circonstances où la partie de réglage (15) n'est pas entraînée en rotation, pour que les tiges télescopiques (2) puissent être supportées de façon stable sans se desserrer.
