Abstract
A self-leveling sleep surface frame includes linear actuators at each corner of a sleep surface frame connected by bi-directional joints to a plurality of telescoping beams which allows for the length of the beams to change and the angle of the connections between the beams and joints to adjust while achieving a level position for the sleep surface frame when a sleeper vehicle is on an unlevel surface.
Claims18
A self-leveling sleep surface frame for use in a sleeper vehicle, comprising:
- a sleep surface frame having at least four beams in a generally rectangular shape with four assembled corners created by the intersection of the distal ends of two paired beams, wherein at least three of the beams are telescoping beams;
- at least three of the assembled corners being individually coupled with a bi-directional joint;
- at least three linear actuators for raising and lowering a portion of the sleep surface frame that are individually coupled via a coupling structure to at least three of the bi-directional joints;
- a mounting means coupled to each linear actuator which secures the self-leveling sleep surface frame inside the sleeper vehicle;
- a controller unit which is operatively connected to and causes at least one actuator motor of at least one of the linear actuators to move;
- and
- a power unit to supply power to the controller unit and the linear actuators.
