Abstract
A sofa bed is configured to be switched between a sofa configuration and a bed configuration. The sofa bed includes a base frame, a middle frame rotatably coupled to the base frame, a seat-and-foot frame rotatably coupled to the middle frame, a back-and-head frame rotatably coupled to the base frame, and a spring coupled between at least two of the base frame, the middle frame, the seat-and-back frame, and the back-and-head frame.
Claims14
A sofa bed configured to be switched between a sofa configuration and a bed configuration, the sofa bed comprising:
- a base frame;
- a middle frame coupled to the base frame and configured to be rotated between a first position in the sofa configuration and a second position in the bed configuration, wherein the middle frame is configured to rotate substantially 180 degrees between the first position and the second position;
- a seat-and-foot frame rotatably coupled to the middle frame;
- a back-and-head frame rotatably coupled to the base frame;
- and
- a gas compression spring coupled between the middle frame and the base frame and configured to urge the middle frame to switch from the sofa configuration to the bed configuration and also from the bed configuration to the sofa configuration.
A sofa bed configured to be switched between a sofa configuration and a bed configuration, the sofa bed comprising:
- a base frame;
- a middle frame rotatably coupled to the base frame;
- a seat-and-foot frame rotatably coupled to the middle frame;
- a back-and-head frame rotatably coupled to the base frame;
- and
- a spring connected at one end to the base frame and connected at the other end to the middle frame and arranged to be compressed in both the sofa configuration and the bed configuration, wherein the spring is arranged to initially become less compressed and then more compressed when the middle frame is between the sofa configuration and the bed configuration as the middle frame rotates from the sofa configuration and from the bed configuration.
