Claims14
A sofa bed, comprising:
- a plurality of elastic modules each comprising a conical spring and a spring bracket holding the conical spring;
- a main body frame formed with a plurality of slide rails configured to engage with a bottom portion of the spring bracket so that the plurality of elastic modules can slide on the slide rails;
- an armrest frame on both sides of the main body;
- the main body frame configured to be folded along a fold-in-half line perpendicular to an extending direction of the slide rail so as to switch between a folded state and an in-use state, the slide rail forming a slide rail opening at the fold-in-half line when the main body frame is in the folded state, and the slide rail opening closed when the main body frame is in the in-use state;
- the slide rails on the main body frame configured such that when the main body frame is in the folded state, the plurality of elastic modules can be mounted on the slide rails from an outer side of the main body frame via the slide rail openings and slide toward ends of the slide rails, the plurality of elastic modules arranged on a front side of the main body frame facing when in the folded state.
