More Information
Summary:A lift assist mechanism is provided for assisting lifting of a movable component that can move between lowered and raised positions relative to a fixed structure. The lift assist mechanism includes a lift assist spring connected to a spring shaft, and an elongated track in which an end of the lift assist spring or an end of the spring shaft are movably engaged. A spring lock restrains movement of the spring shaft when a lift assist is not required, and releases the spring shaft when a lift assist is required. La présente invention se rapporte à un mécanisme d'aide au levage destiné à faciliter le levage d'un composant mobile qui peut se déplacer entre des positions abaissée et surélevée par rapport à une structure fixe. Le mécanisme d'aide au levage comprend un ressort d'aide au levage relié à une tige de ressort, et un rail allongé dans lequel une extrémité du ressort d'aide au levage ou une extrémité de la tige de ressort est en prise mobile. Une serrure à ressort limite le déplacement de la tige de ressort lorsqu'une aide au levage n'est pas nécessaire, et relâche la tige de ressort lorsqu'une aide au levage est nécessaire.
