Motion bed

摘要

A bed assembly (1) has a stationary frame (2), which sits on a floor and supports the entire bed assembly. A central frame (4) moves in a first horizontal direction relative to the stationary frame, and is moveably supported by the stationary frame. An outer frame (8) moves in a second horizontal direction relative to the second frame, and is moveably supported by the second frame.

1. 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 (6a); 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 (6b) 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.
