Abstract
A personal lift mechanism and method are disclosed. The personal lift mechanism comprises: a lift having a base structure which pivotally retains a pair of struts which are pivotally coupled with a lift platform; an actuator coupled with at least one of the pair of struts; and a damper coupled with the actuator and operable to dissipate kinetic energy transferred between the lift platform and the actuator. In this way, less mechanically-robust components are required for the lift mechanism, damage to those components and the actuator is less likely, and any load on the lift platform and/or base structure will experience reduced shock due to the energy being instead dissipated within the damper.

A personal lift mechanism, comprising:
- a lift having a base structure which pivotally retains a pair of struts which are pivotally coupled with a lift platform;
- an actuator coupled with at least one of said pair of struts;
- and
- a damper coupled with said actuator and operable to dissipate kinetic energy transferred from said lift platform to said actuator;
- and
- a pivoting coupler and wherein a displacement of said actuator in a first direction due to said kinetic energy is translated by said pivoting coupler to a displacement of said damper in a second direction;
- wherein said pivoting coupler comprises a rocker arm pivotally located on said base structure;
- and
- wherein said rocker arm has an actuation lever part extending from a pivot which is coupled with said actuator and a damper lever part extending from said pivot which is coupled with said damper.
