发明名称 Operable ramp
摘要 An operable ramp is moveable between a stowed position and a deployed position. The operable ramp includes a ramp panel rotatable about a first end. A second end of the ramp panel is lower in the deployed position than in the stowed position. A rotatable support supports a second end of the ramp panel, and a drive assembly selectively rotates the support (1) in a first direction to lower the second end of the ramp panel and (2) in a second direction to raise the second end of the ramp panel. A stop limits rotation of the support in the second direction when the operable ramp is in the stowed position. The weight of the ramp panel biases the support in the second direction, i.e., toward the stop, when the operable ramp is in the stowed position.

主权项 1. An operable ramp moveable between a stowed position and a deployed position, the operable ramp comprising: (a) a ramp panel rotatably coupled at a first end about a first axis, a second end of the ramp panel being lower in the deployed position than in the stowed position; (b) a support rotatable about a second axis, the support supporting the second end of the ramp panel; (c) a drive assembly operably coupled to the support to selectively rotate the support (1) in a first direction to lower the second end of the ramp panel and (2) in a second direction raise the second end of the ramp panel; and (d) a stop limiting rotation of the support in the second direction when the operable ramp is in the stowed position, wherein a weight of the ramp panel biases the support to rotate in the second direction when the operable ramp is in the stowed position.
