Abstract
(EN) Torsion spring tensioning tool (100) for tensioning a torsion spring of a counterbalancing mechanism of an overhead door, wherein the torsion spring tensioning tool (100) comprises a housing (80), a gear wheel arrangement (20) adapted to be mounted on a shaft of the counterbalancing mechanism, said gear wheel arrangement (20) comprising a gear wheel (21) rotatably arranged in the housing (80), the torsion spring tensioning tool (100) further comprising a gear mechanism (54) coupled to the gear wheel (21) for rotating said gear wheel (21). The gear wheel arrangement (20) comprises a fixating arrangement (32) fix to the gear wheel (21) and adapted engage the shaft of the counterbalancing mechanism and transmit a rotational movement from the gear wheel (21) to the torsion spring.
(FR) L'invention concerne un outil de tension de ressort de torsion (100) pour tendre un ressort de torsion d'un mécanisme de contre-poids d'une porte basculante, l'outil de tension de ressort de torsion (100) comprenant un boîtier (80), un agencement de roue dentée (20) conçu pour être monté sur un arbre du mécanisme de contre-poids, ledit agencement de roue dentée (20) comprenant une roue dentée (21) agencée en rotation dans le boîtier (80), l'outil de tension de ressort de torsion (100) comprenant en outre un mécanisme d'engrenage (54) couplé à la roue dentée (21) pour faire tourner ladite roue dentée (21). L'agencement de roue dentée (20) comprend un agencement de fixation (32) pour fixer la roue dentée (21) et conçu pour s'engager avec l'arbre du mécanisme de contre-poids et transmettre un mouvement de rotation de la roue dentée (21) au ressort de torsion.
