AIR SPRING COUNTERBALANCE A fluid-based spring counterbalance mechanism (100) comprising an elastic flexible fluid based spring (110) disposed between two surfaces (120, 130) is used to support some or all of the weight of a movable barrier (1101). A linkage mechanism comprising at least one rotating rotatable shaft is configured to receive rotational motion from a jackshaft associated with the movable barrier (1101). A translational mechanism (150) coupled to the at least one rotating shaft and coupled to at least one of the two surfaces (120, 130) is configured to compress the flexible fluid-based spring (110) between the two surfaces (120, 130) in response to rotation of the rotatable shaft. By compressing the fluid-based spring (110), the counterbalance mechanism (100) provides a force that partially or fully supports the weight of the movable barrier (1101). --------------- 1 2 |
