Title (EN) FLOATING TORSION SPRING TENSION ADJUSTMENT SYSTEM
(FR) SYSTÈME D'AJUSTEMENT DE TENSION DE RESSORT DE TORSION FLOTTANT
Abstract:
(EN) An overhead door having a floating spring adjustment is presented. Tension is applied to a torsion spring while the door is in the open, minimal tension state. One end of the torsion spring is fixed to a spring tension trolley. The trolley translates within a trolley guide mounted to the building structure. The other end of the torsion spring is fixed to a shaft running through the torsion spring. This allows the torsion spring to change in length as the number of coils shrink and grow through door operation thereby eliminating the "snake-like" or serpentine appearance from an improper fixed torsion spring length.
(FR) La présente invention concerne une porte basculante qui présente un ajustement de ressort flottant. Une tension est appliquée sur un ressort de torsion alors que la porte est dans l'état ouvert à tension minimale. Une extrémité du ressort de torsion est fixée à un chariot de tension de ressort. Le chariot se déplace à l'intérieur d'un guidage de chariot monté sur la structure de bâtiment. L'autre extrémité du ressort de torsion est fixée à un arbre qui s'étend à travers le ressort de torsion. Ceci permet au ressort de torsion de changer de longueur lorsque le nombre de spires diminuent et augmente par l'intermédiaire d'actionnement de porte, ce qui permet d'éliminer l'apparence "en serpent" ou en serpentin à partir d'une longueur de ressort de torsion fixe incorrecte.
