Abstract

The utility model provides an adjustable spring bed which can change from a sofa into a bed or from a bed into a sofa by regulating the angle of the backrest and the linkage seats; the spring bed connects the backrest with the seat by using hinges in large angle shape; the backrest, the seat and the bottom seat frame are respectively connected by using movable type support columns through connecting pieces; thus, the backrest and the seat can be connected to move and can also be folded relatively; the backrest can regulate the inclination angle of the sofa backrest by using the movable type support columns. The utility model has the advantages of reasonable design, novel structure, convenient operation, and comfortable sitting and sleeping; the adjustable spring bed is an ideal article for daily use.

Description

Adjustable spring bed

The utility model relates to and a kind ofly can be become bed or be become the adjustable divan of sofa by bed by sofa by regulating backrest angle interlock seat.

Existingly mostly be that by rotating the divan that backrest, upset handrail and support column change seat and underframe are solidified as a whole, adopt traditional type hinge connection backrest and seat, be converted into sofa after inclination of the seat backrest fix.It changes complicated, and the dismounting difficulty is used inconvenience.

The utility model provides a kind of novel adjustable divan.Adopt big dihedral hinge (hinge) that backrest is connected with the seat, adopt movable support column respectively backrest to be connected with pony sill with the seat, but make backrest and seat interlock and relative folding by connector.Backrest adopts adjustable support column can regulate the angle of sofa backrest.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the three-dimensional diagrammatic sketch of a kind of sofa bedstead of the present utility model.

Fig. 2 is the diagrammatic sketch that Fig. 1 becomes sofa.

Fig. 3 is that the utility model connector is cutaway view and the left view that A amplifies to rotation among Fig. 2.

Fig. 4 is that the utility model regulating sleeve is the amplification view of B among Fig. 1.

Fig. 5 is that the utility model dihedral hinge is the enlarged drawing of C among Fig. 1.

The utility model by underframe, the head of a bed, mattress, seat back frame 1, seat frame 8, dihedral hinge 4 and before, during and after

pillar

7,5,2 and connector 3, column 11 formed.Seat back frame 1 is connected by hinge 4 with seat frame 8, and is connected with underframe by connector 3 by

pillar

7,5,2 respectively, and formation can be become bed or be become by bed the variable sofa bedstead of sofa by adjusting seat back frame angle interlock seat frame 8 by sofa.The connection sheet 6 of bedstead plates mattress, connects the head of a bed (also being sofa handrail) by the leg apertura lateralis, just is the mode divan.

Underframe has two front support legs 9 and two rear legs 12, is combined as a whole by four stulls 10 between the leg, and universal wheel all is equipped with in the leg bottom, is convenient to move.

Seat back frame 1 and seat frame 8 are made by metal materials such as square tube or T shape pipe, pipes.

Hinge 4 is made up of two moving

plates

18 and 19 on angle axle.As shown in Figure 5, two moving plates, 18 1 ends are connected by angle axle 19.The other end connects seat back frame 1 and seat frame 8 respectively, and to make two frames can be that the center relatively rotates with angle axle 19.

Pillar is respectively front standing pillar 7, B-C post 5 and back prop 2.As shown in Figure 1, 2, front standing pillar 7 tops connect seat frame 8, and the bottom is connected on the angle of cut of the stull 10 in the front support leg 9; B-C post 5 tops connect seat frame 8, and the bottom is connected in the middle part of stull 10; Back prop 2 is pillar fixed length or that be equipped with regulating sleeve 20 flexibles adjusting, and its top connects seat back frame 1, and the bottom is connected on the angle of cut of stulls 10 in the rear leg 12.

Connector 3 is made up of axle sleeve 14 and shaft coupling 13, pivot pin 15 or axle bed 17, screw 16.Axle sleeve 14 is the pipe shape, directly is welded in the both ends of each pillar.Shown in Fig. 3 a, shaft coupling 13 is cylindric, is individually fixed on the stull 10 of underframe or seat back frame 1, the seat frame 8.Axle sleeve 14 is assemblied on the shaft coupling 13 with pivot pin 15 lockings, axle sleeve 14 and shaft coupling 13 being formed movingly and can make pillar is shown in center rotation or the employing Fig. 3 b with shaft coupling 13, and axle bed 17 is separately fixed on stull 10, seat back frame 1, the seat frame 8.With screw 16 axle sleeve 14 is connected formation movingly with axle bed 17.

Column 11 weldering is formed in the stull 10 of underframe, is used for the utility model and is become by bed and be sofa rear branching holder position frame 8.

Regulating sleeve 20 as shown in Figure 4, the one end is shaped on the left-hand screw thread, the other end is shaped on the dextrad screw thread, is assemblied on the back prop 2 that is shaped on respective threaded.Make it to rotate regulating sleeve 20, the just longitudinal extension of the pillar of connection.In order to regulate the inclination angle of sofa backrest.

The utility model exhibition is stretched into bed, in (as Fig. 1), front standing pillar is in vertical position, and and rear leg supporting seat back frame and seat frame horizontal.In the time of need changing over sofa, turn to lift the adjusting seat back frame and move behind the interlock seat frame simultaneously, column and front support leg supporting seat, back prop supports the backrest (see figure 2), promptly becomes sofa.Also rotatable regulating sleeve makes back prop stretch or contract, and makes the sofa backrest be positioned at the appropriate location.If become bed by sofa, pass backrest interlock seat backward, preceding, B-C post erects, and makes backrest and seat be horizontal level, just recovers to become bed.

The utility model novel structure, reasonable in design, sitting and lying is comfortable, dismounting is simple and easy, easy to use, be a kind of desirable novel daily necessities.
