Description

Multi-purpose sofa

The utility model relates to a kind of backrest that turns forward, and to become the having seat, crouch of bed, storing etc. many with the couches that are coated with.

Disclosing a kind of application number in the Chinese patent gazette on November 12nd, 1 is 85204683 " seat, crouch, store studiocouch ".Its objective is " solve the existing rugged problem of similar sofa bed surface when pulling out, and simplify the syndeton between the base plate, reduce product cost ".Structurally be adopted two can be overlapping seat surface framework combined crosswise and the movable backrest plate that can turn down forward and seat surface framework between can overlap etc.Its weak point is still to be difficult to guarantee that each level of bed surface and sofa seat face length degree are that its overall dimensions distribution of bed surface width is difficult to rationally be suitable for after backrest plate is turned down.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of multipurpose, the tiltable assembly type three of seat surface or four-player couch is provided.

The purpose of this utility model can realize by following structure:

Multi purpose sofa, comprise storage tank formula load-bearing s crossbeam frame, the handrail or the handrails framework of fixedlying connected with the s crossbeam frame two ends, the lower end is by the rotatable backboard of pivot structure or hinge and fixing rear plate front end flexible connection above the s crossbeam frame, but the pull that s crossbeam frame is placed above becomes the movable base plate of bed surface, the software seat cushion and the software backing cushion of above the seat board and backboard front, also has other such as s crossbeam frame and handrails framework, between handrails framework and multi-functional the case and assembling adjusting and fastening structure between each parts, the spacing supporting structure of movable parts and extend supplementary structures such as displacement and storing.Special feature of the present utility model is: the plane is the thickness of backboard with being in before pulling out as the parallel distance on plane on the movable base plate of horizontal sofa seat board status on the rear plate above the described s crossbeam frame, turns down forward and can constitute a smooth single bed surface with the rear plate above the s crossbeam frame by surface bearing on the movable base plate to realize backboard; Be fixed with several slidably longerons below the movable base plate, the slip longeron is that to put the fixing vertical longeron guide rail support in vertical clapboard and side thereof by the several Zhang Zong in the s crossbeam frame spacing, above the longitudinal rail rear end and the discrepancy in elevation between above the front end be the thickness of backboard, this discrepancy in elevation movable base plate is extracted out put in place rise above its rear end, back with back plane place above the s crossbeam frame at grade; The movable base plate front end is provided with and can makes its front end be higher than the rear end to form the inclination seat surface or increase auxiliary supporting leg as the side of the double bed surface of part, and auxiliary supporting leg is the folding supporting leg that can uprise.Lengthening highly is the thickness of backboard, thus can reach sofa take one's seat comfortable, assist the reliable and stable dual purpose of bed surface; The rear portion of slip longeron is provided with and tops bar, the extension of wedge down, above the extension and the step parallel distance between movable base plate top be the thickness of backboard.Like this, after movable base plate was pulled out, its front end was by increasing auxiliary outrigger support, and its rear end keeps the movable base plate level by the longitudinal rail front end below the wedge of supporting slip longeron extension.The backboard of the rear plate front end above the s crossbeam frame is turned down the top bar surface bearing of its front end of back by extension, slip longeron rear portion.The double bed surface that guarantees movable base plate, backboard and rear plate thus and constituted is smooth firmly.
