Description

Folded metal frame multifunction sofa

The utility model relates to a kind of multifunction sofa, particularly relates to motionless only the touching with have gentle hands of a kind of base and draws just deployable folding sitting-lying double-purpose metal frame sofa.

At present, steelframe Folding sofa on the market, the steelframe combination of two foldable structures is generally only used in its paving, makes its sofa time spent floor space bigger; As the bed time spent, the function that reaches a usefulness is rotated in its action conversion just back part, this by the mechanism of backrest around fixing point (or line) rotation, its complex structure, need more accessory, improved cost, and easy break-down, also need movable base could realize sitting-lying double-purpose before the operation, very inconvenient.

The purpose of this utility model provides the multifunction sofa of a kind of simple in structure, reliable in action and easy to operate sofa and bed dual-purpose.

Above-mentioned purpose is achieved in that the utility model is by pony sill, folding paving frame with place the paving cushion three parts on the frame of paving to form, wherein folding paving frame adopt by before, during and after three hinged steelframe foldable structures that constitute of rectangle rack, on the adjacent preceding rectangle position of preceding, middle rectangle rack, the balanced lever jacking device is housed, the balance propulsion arm of jacking device before lifting gently during rectangle rack over against head on adjacent in bottom before the rectangle rack, this balance propulsion arm is under external force in the pushing tow, the back rectangle rack upwards is folded into the sofa back part.Being used as leisure and sitting and use the sofa leaf, in, afterwards rectangle rack is to being folded into back part, preceding rectangle rack places on the pony sill, becomes the part of sofa attic base; When needs are done bed with (crouch with), only need directly outwards (forwards promptly) pulling before rectangle rack get final product: preceding rectangle rack affects hinged successively middle rectangle rack, back rectangle rack is open and flat forward to be opened, and forms the flat spreading part of using for sleeping in.When the utility model transfers seat with the sofa state to by the user mode with bed for sleeping in, only need lift preceding rectangle rack gently, the balance propulsion arm of jacking device is with regard to the right bottom before the rectangle rack in head on of order, rectangle rack before thereupon promoting backward, then in the balance propulsion arm pushing tow, back two rectangle racks are upwards to being folded into the sofa back part, preceding rectangle rack is overlapped on the pony sill get final product.

Be with a pillow position crane in the rectangle rack of above-mentioned back, crane both sides, pillow position are provided with the slip recliner of being made up of support bar, slip cap and ratch, and realization headrest portion is the function of lifting smoothly also.

There is draw-in groove at interval the inboard of rectangle rack before, during and after above-mentioned, and the wood ribbon that constitutes the paving directly inserts in its draw-in groove, is provided with the tank bracket crossbeam below wood ribbon.This design feature can be guaranteed the extended immobilization wood ribbon, makes its difficult drop-off, and is both durable in use, increases the comfort when using again.

On the back horizontal tank bracket of above-mentioned pony sill, is furnished with the backstop headstock.The sofa time spent, this backstop headstock can strengthen backrest stability, and it was made the head of a bed and partly used the time spent of crouching.

The pony sill of the present utility model left and right sides is provided with by upper and lower crossbeam and constitutes rectangular frame structure, to strengthen the steadiness of pony sill, makes it can bear the folding movement strength of paving frame for a long time and plays positioning action.On the entablature of this rectangular frame, be connected with handrail and/or pallet, to increase function corresponding.

The utlity model has following advantage: 1, adopt three rectangle steelframe foldable structures, be equipped with the balanced lever jacking device, realize that smoothly pushing tow is folding, realize sitting simple and easy conversion with sofa and bed usefulness, simple in structure, compact, flexible movements, operation is reliable, convenient; 2, adopt pillow position crane and angle modulation structure thereof, increase headrest portion elevating function; 3, adopt wood ribbon straight cutting tank bracket draw-in groove structure and base rectangular frame structure, strengthen the steadiness of this product, beautiful and comfortable, long service life.
