Patent ID: 8856982

Claim:
A bed assembly ( 1 ) comprises: a stationary frame ( 2 ), which sits on the floor and supports the entire bed assembly; a second frame ( 4 ), is configured to continuously oscillate in a first horizontal direction relative to the stationary frame, and is moveably supported by the stationary frame; a third frame ( 8 ), which is configured to continuously oscillate in a second horizontal direction relative to the second frame, and is moveably supported by the second frame; the second frame ( 4 ) hangs from the stationary frame ( 2 ) using four swing arms ( 6 a ); the second frame hangs outside the stationary frame ( 2 ), between the stationary frame ( 2 ) and the third frame ( 8 ); the four swing arms each describe an arc movement, and the second frame is gravity-biased to hang at the bottom of said arc; the third frame hangs from the second frame using a second four swing arms ( 6 b ) the second four swing arms each describe an arc movement, and the third frame is gravity-biased to hang at the bottom of said arc.
