Patent ID: 8656531

Claim:
A cot having an assist arm, comprising: a first side rail having a first connection mechanism; a second side rail having a second connection mechanism; a leg secured to the second side rail; a pivoting mechanism that pivotally secures the leg to the second side rail; a support fabric having a first peripheral side channel shaped to receive the first side rail and a second peripheral side channel shaped to receive the second side rail, the first peripheral side channel and the second peripheral side channel being disposed on opposing sides of the support fabric; an end rail having a longitudinal axis, a third connection mechanism, a fourth connection mechanism, and a fifth connection mechanism, the third connection mechanism shaped to engage the first connection mechanism and located at a first fixed point along the longitudinal axis, the fourth connection mechanism shaped to engage with the second connection mechanism and located at a second fixed point along the longitudinal axis, the fifth connection mechanism located at a third fixed point between the first fixed point and the second fixed point relative to the longitudinal axis of the end rail; and an arm having a proximal end and a distal end, the proximal end pivotally secured to at least the leg or the pivoting mechanism, the distal end comprising a sixth connection mechanism shaped to interface with the fifth connection mechanism, wherein the arm is dimensioned such that when the sixth connection mechanism is engaged with the fifth connection mechanism and the first connection mechanism is engaged with the third connection mechanism, a pivotal radius of the fourth connection mechanism of the end rail intersects with an engaging position in which the fourth connection mechanism engages the second connection mechanism.
