Patent ID: 7665161

Claim:
A retractable bed, comprising: a bed comprising a frame for holding a mattress and legs; at least one motor for raising and lowering said bed through vertical displacement, the motor being disposed separately from the bed and a ceiling so that it does not move with the bed as the bed is raised and lowered; a block assembly coupled to at least one motor and load bearing lines for transferring a load associated with the bed to the motor; a remote control unit coupled to at least one motor; at least one sensor for determining when the bed is in the lowered or raised configurations; an output device for outputting a visual or acoustic indicia that the bed is in the lowered or raised configuration; wherein said bed will come into contact with a floor when the bed is in the lowered configuration thereby permitting a person to sleep on the bed; wherein said bed will be raised to a vertical location adjacent to the ceiling when the bed is in the raised configuration thereby permitting a person to pass under the bed; and wherein said bed can be changed from the lowered configuration to the raised configuration through vertical displacement without any rotational displacement of the frame.
