Here, every joint folding bed mainly is made of dual-gripper bar, the canvas that is fixed between the dual-gripper bar, connecting channel bar by one between every joint folding bed flexibly connects, the cross section of channel bar is the groove shape, the termination of channel bar is provided with the clamping breach, and the termination of the support bar of folding bed is movably connected on the clamping breach of channel bar.During use, be subjected to the restriction of groove, every joint folding bed can only overturn 90 °, and the pressure direction that the direction when folding bed is opened upset applies in bed when couching with the people is consistent, has so just guaranteed the enabling capabilities of bed and straight comfortableness.

In the sofa cavity, be symmetrical set a support, the folding bed cramp bar of front couples together by front and back two connecting rods and support, front rod is the L shape, the two ends of front rod are actively socketed on respectively on front folding bed cramp bar front end and the support, the back link two ends are actively socketed on respectively on folding bed cramp bar middle part, front and the support, front rod is higher than the loose joint point of back link on support at the point of the loose joint on the support, is provided with tension spring between the bending place of L shape front rod and support.During use, mention the folding bed of front, front rod is rotated along support loose joint point, cross the dead point until the loose joint point of front rod on preceding folding bed bracing frame, under the effect of tension spring, hold up, and folding spring mattress bed is propped, folding spring mattress bed is sent outside the sofa cavity together with back link.Because the pulling direction of spring and its are at the tie point of front rod and the loose joint point of front rod on support in line, therefore, front-rear linkage and front folding bed bearing support form a stable supporting construction.In the time of need putting into folding spring mattress bed in the sofa cavity, can mention the front folding bed earlier, the front end of front folding bed is pressed, when front rod after the loose joint point on the folding bed support bar is walked around the dead point in front, under the effect of tension spring, folding spring mattress bed is sent in the cavity of sofa.

In order to make the folded spring bed after the expansion firm, between feet and channel bar, be provided with L shape stationary links, the upper end of L shape stationary links is movably connected on the feet, the bottom of L shape stationary links is movably connected on the channel bar, be provided with stationary links between the hook end of L shape stationary links and the support bar of next stage folding bed, length between 2 loose joint points of stationary links adds the montant bottom loose joint point length sum of its loose joint point on the hook end of L shape stationary links and L shape stationary links, more than or equal to L shape stationary links in length and this loose joint point and stationary links loose joint point sum on this support bar between loose joint point on the point of the loose joint on the channel bar and channel bar and the next stage folding bed support bar.During use, open feet earlier, open folding bed along the loose joint point between support bar and channel bar then, be subjected to the pulling of stationary links and the restriction of channel bar, the montant of feet, L shape stationary links, bearing support form a firm triangle support frame at loose joint point on the support bar and L shape stationary links between the loose joint point on the channel bar, the feet after opening can be maintained static.When needing the folded spring bed, at first folding bed to be dug, could the feet upset is folding.

Compared with the prior art the utility model has when couching can launch a big bed, when not needing to couch, can draw into a sofa in, can not influence the moulding of sofa itself and the advantage of comfort level thereof, and the folding storage of big bed is easy, opens when using firmly reliable.
