Patent ID: 7013510

Claim:
A low profile bed comprising: (a) a mattress support frame, (b) at least one wheel frame pivotably mounted to said mattress support frame for movement between a folded position and an unfolded position, (c) a leverage member pivotably mounted to said at least one wheel frame, and, (d) a lift actuator connecting between said mattress support frame and said leverage member, said lift actuator for extending and contracting movement between a retracted position and an extended position, said lift actuator and said leverage member arranged such that initial extension of said lift actuator causes said leverage member to push against said mattress support frame and urge said at least one wheel frame away from said mattress support frame until said wheel frame reaches a partially unfolded position and such that subsequent extension of said lift actuator powers further unfolding of said at least one wheel frame from said partially unfolded position to a fully unfolded position.
