Abstract
The utility model relates to a dual-purpose bed of sofa with twist lever-type belonging to the field of woodenware furniture; the bed body of the utility model is three twisting type, and namely, the bed surface is divided into three independent bed drawers which are connected by the hinges; the lower side of the front bed drawer is provided with a wheel, and the three bed drawers form a bed surface; the front bed drawer is moved backward to form a seat cushion, and the middle and the rear bed drawers areoppositely erected to form the back rest of the sofa.
Description
The utility model belongs to carpenter's furniture and manufactures the field.
Folding bed can improve the interior space, and both artistic and practical, at present, common folding bed mostly is two folding formulas on the market, mainly contain two kinds of forms: a kind of is based on bed, and it is divided into 0.7 meter of 0.8 meter on backrest and seat cushion with the wide of bed to (1.5 meters), and this form is more suitable to bed.But after being converted into sofa, because seat cushion is dark excessively, ratio is improper, influence attractive in appearance and comfortable, and folding inconvenient (need) around behind bed, operating.Another kind is based on sofa, and backrest is motionless, double-deck seat cushion is routed up expanded into bed, and is easy to operate though it is attractive in appearance, because bed surface only has 1.1 meters wide, can not satisfy the requirement of double bed, therefore, can not replace bed.
The purpose of this utility model provides a kind of warpage lever Dual-purpose sofabed.It combines promptly saves the space and again can one makes dual-purpose common advantage in above-mentioned two examples.For example overcome shortcoming that they exist separately: ratio is improper, bed surface is narrow, folding inconvenience.
The purpose of this utility model is achieved in that a body is three-bend, and promptly bed surface is divided into three independently bed drawers, and we are called preceding drawer, middle drawer, back drawer, connect with hinge therebetween, wheel is installed below the preceding drawer, and during expansion, three bed drawers form a plane.Be bed surface, when drawing in, preceding drawer translation backward becomes seat cushion, in, back two drawers opposing hold up to close be close together, the length that the length summation can satisfy bed after forming sofa backrest, three bed drawers and launching is to requiring.This direction be perpendicular to folding shaft to.Like this, bedside, the another side length of promptly parallel with folding shaft bed drawer just can choose at random, and can be made into the big bed of three people's to five humans, and their folding amount, it is constant saving space factor.
More than be the partly movable of bed.Its support section is such: the two ends, the left and right sides of bed are established between handrail two handrails and are linked to each other from one side.Another side opens wide, and overlooks to be football door shape, to guarantee seesawing of bed body.For attractive in appearance, link two arm rests, more than bed surface, make the head of a bed of definite shape.Movable partly (bed surface) embeds the football door shape and structure from the back drawer, and certain position punching on the left and right sides wooden frame of back drawer is worn axle with handrail and connect, and this point is folding axle center.The position in axle center is definite like this: in the bed, the back is after two drawers draw into the sofa backrest in, will abut against on the head of a bed, the proper angle for the backrest that keeps sofa requires the following end distance head of a bed vertical plane of backrest to keep a segment distance.At this moment, in the hole apart from the distance of head of a bed vertical plane be exactly on the drawer of bed back in the hole apart from the length of rear end.
For folding convenient, adopt lever to tend to act, lever vertically is installed in bed down, and fulcrum is established in the middle of pedal is installed in the outer end, during operation, stands in a front end, with foot-operated pedal down application point is risen.In getting up, the junction of back drawer, push away inward and finish folding process then, because bed can not hold the lever Len req after drawing into sofa in.Therefore, designed the warpage lever.It is that the length of lever main body is divided into two partly.Carrying out the irreversibility live axle then connects.Do the time spent, be a straight-bar; After finishing its function, just upwards tortuous.
For folding laborsaving, add to help at the balance pivot place and rise spring.It is to adopt the form of mouse trap Huang to help depress pedal, between the partly movable and supporting construction of bed, establish to help and draw the bullet Huang, its effect one be make when folding laborsaving; The 2nd, three bed drawer tensions can be one when setting level.
The utility model owing to take perpendicular to folding shaft to direction for bed long (this point is routine just the opposite with above-mentioned two) bedside can be selected arbitrarily, like this, just overcome the narrow shortcoming of bed surface in the precedent, not only can replace bed fully, can also satisfy the requirement of many humans.Therefore, it is applicable to the family more than three mouthfuls of a Room, can overcome the improper shortcoming of ratio in the precedent because employing is three-bend, because the warpage lever is tended to act and the yellow afterburning structure of bullet, folding process in the precedent is simplified greatly, and a need one is stepped on one and is pushed away, and needs 2~4 second time approximately.
The concrete structure of utility model is provided by following examples and accompanying drawing.
