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