Abstract:
A bed assembly having a bed capable of being shifted between an upper stored position and a lower position for sleeping, comprising:a frame for supporting a mattress capable of being shifted between the upper stored and lower positions, said frame having a first half and a second half; the second half of said frame being mounted to first and second rigid supports by two spaced-apart vertically extending guides, said guides having respective stops at said lower position for limiting downward movement of the second half of said frame; a pair of swing arms pivotally mounted to third and fourth rigid supports adjacent the upper stored position of said frame, with said arms engaging linkages coupled to the frame at the first half of said frame; said swing arms including arrangements permitting movement of said linkages along said swing arms from said upper stored position to said lower position preventing further downward movement of said linkages, said swing arms rotating as one edge of said bed is lowered from said upper stored position toward said lower position; resilient counterbalancing arrangements which are compressed when said mattress and frame are shifted downward, and which apply upward force to assist in restoring said mattress and frame to the upper stored position.
