Patent ID: 8528131

Claim:
A cot having a frame for supporting a bed sheet, the frame comprising: a pair of opposed side rails, each of said opposed side rails including first and second parts pivotally interconnected to one another; a pair of opposed end rails; each of said end rails having a first segment and a second segment, each of the segments having a first end and a second end, one end of each segment being pivotally attached to respective ones of said side rails; a channel member adapted to receive and pivotally mount a second end of each end rail segment to close the frame in the bed sheet supporting position of the frame, the second end of each end rail segment having at least one reduced dimension as compared to the first end of each end rail segment, the channel member being pivotally mounted to the second end of each end rail segment to permit vertical upward movement of said end rail segments, the pivot point of the second end of each end rail segment being internal to the channel member such that a downward force on the end rails in the bed sheet supporting position the cot forces further engagement of the second end of each end rail segment with the channel member; and at least a pair of foldable cot supports attached to at least one of said side rails and said end rails, said cot supports fold inwardly as the end rail segments move vertically upwardly so that the vertical upward movement of the end rail segments causes at least one of the pair of foldable cot supports to fold inwardly to initiate a cot folding procedure.
