Abstract

The utility model sofa with rocking chair function is a piece of furniture for movable lying and sleeping which integrates the functions of a sofa and a rocking chair. A plurality of pulleys supporting in the chute of the seat frame are installed on the cradle horizontal beam made from steel. The back frame is hinged with the seat pat frame, the angle thereof is non-stage tunable because of the size of the bearing force, and the restoring position spring force is in balance with the bearing force. The sofa with rocking chair function need not be provided with a control mechanism, the status of sitting, lying, sleeping, rocking can be altered at any time, and the forth and rear centre of gravity can be kept balanced. When the sofa with rocking chair function does not need to rock, the hook on the guide track can hook the cradle to serve as a fixed sofa.

Description

Sofa with rocking chair function

The utility model is relevant with furniture, and is especially relevant with multi-functional Disassembling sofa.

Traditional sofa all is by fixed wooden or hophornbeam framework, backrest, and cushion, handrail is formed.All be by using helical spring in backrest and the cushion, the fixed angle of backrest and cushion or one to two variation can be arranged.The shortcoming of this sofa is that framework is shaky or very thick.Elasticity is concentrated no comfort, and the angle of backrest and cushion is single, can not adapt to the needs of any variation.More can not shake.

Traditional rocking chair that disappears does not have the comfortable and attractive in appearance of sofa, and the angle of backrest needs to set up in advance, and center of gravity changes with the angle of backrest, and flat more and center of gravity that backrest is put influences shaking and comfort of chair more backward.Traditional free and unfettered rocking chair can't be put the chair that fixes by wall and use.

It is stepless adjustable that the purpose of this utility model provides a kind of backrest angle, and center of gravity remains unchanged substantially in any angle position, and can be used as fixedly, sofa also can be used as strong, the easy to use multifunctional movable chair of comfort that free and unfettered rocking chair uses.

Chair frame of the present utility model is the reel cage of steel, on the horizontal junction member of reel cage several sliding parts is arranged.The chute that cooperates with sliding part is arranged on the frame of seat frame, and sliding part supporting cushion frame is in chute, and seat frame and back rest are hinged, and has two pull bars to be hinged with back rest and reel cage respectively.The angle of back rest and seat frame is stepless adjustable, has back-moving spring one end to be connected with seat frame, and the other end is connected with reel cage, after the load that makes back rest and seat frame displacement is eliminated, back rest, seat frame is set back put.

Sliding part of the present utility model can be two front wheels and two rear wheels, and pulley base is fixed on the reel cage, and pulley bearing is in the frame groove of mounting.Back-moving spring one end is placed on the interior fixed bar of seat frame, and the other end links to each other with the handle that several sawtooth are arranged, and the sawtooth of handle can be hung on the reel cage horizontal junction member, regulates the pulling force of back-moving spring.Reel cage can be positioned on the guide rail bracket, and guide rail bracket is made by angle steel, and there is axle sleeve both sides, and the protruding axle of reel cage can be placed in the axle sleeve, is hinged with hook on the guide rail bracket, can hang on the nose bar of reel cage fixedly reel cage, and several deflecting rollers are equipped with in the bottom of guide rail bracket.Damaged ground when guide rail bracket both can have been avoided shaking, be convenient to again move.

Seat cushion spring of the present utility model and backrest spring are two ends steel wire with hook and the garden post turn hook knot that a few are arranged is weaved into nettedly, hang in the aperture of seat frame and back rest frame, also several tension springs can be arranged therebetween.The occipitalia of back rest and arm-rest frame spring can hang up the stage casing steel wire by the two ends tension spring and form.

The utility model integrates the advantage and the function of sofa and free and unfettered rocking chair, and the angle of backrest is adjustable arbitrarily, need not to establish in addition operating mechanism, can change into seat at any time, lie, sleeps, shakes state.Under any state, keep center of gravity constant substantially, can fix in the time of need not shaking and lay by wall.Rational in infrastructure, diverse in function, easy to use, comfort is strong.

Following is the utility model embodiment:

The utility model is by reel cage 2, guide rail bracket 1, mounting 3, arm-rest frame 4, back rest 5, and front wheel 16, rear wheel 14, back-moving spring 13 are formed.

Be welded with angle steel 17,18 on the reel cage 2, nose bar 22,23 and structural member 24,25 are equipped with protruding axle 11.Advancing slip wheel carrier 26 usefulness bolts are connected on the angle steel 17.Rear wheel frame 27 usefulness bolts are connected on the reel cage.Forward and backward pulley on the frame of seat 3 has chute and is installed in pulley yoke matches.Back-moving spring 13 1 ends hang on the interior peg 28 of mounting frame, and the other end is connected with handle 12, and the tooth of handle 12 hangs on the angle steel 18.Mounting 3 is hinged with backrest 5.Two pull bars 15 are hinged with reel cage and back rest respectively.

Axle sleeve 30 is arranged on the guide rail bracket 1, and the protruding axle of reel cage can be placed in the axle sleeve.Guide rail bracket is hinged with hook 10, can hang on the nose bar of reel cage fixedly reel cage.Four deflecting rollers 9 are equipped with in the bottom.

Arm-rest frame 5 is hinged with reel cage 2, and the flexible supporting member 29 of its front end is hinged with handrail and reel cage respectively.Arm-rest frame and back rest occipitalia spring can hang up stage casing steel wire 8 by two ends tension spring 7 and form.
