The patent No. is that the utility model patent of ZL96251963.4 discloses a kind of seat turning chair for sleeping in, is made up of folding supporting mechanism, support mechanism, transmission mechanism.Folding supporting mechanism is made up of leg, seat, backboard, and the leg plate is connected the front end of seat, and backboard is connected the rear end of seat, the handrail of seat, and the upper end of backboard is fixed with headrest.Support mechanism is made up of base, leading screw, screw, support.Transmission mechanism is made up of the pole of handle, swing arm, bevel gear, worm reduction gear, eccentric wheel, pole, motion framework, support.This invention both can be worked as chair usefulness, can work as bed again and use.But this swivel chair can not be with the body position deform in same pace, and is comfortable inadequately.

The purpose of this utility model be to provide a kind of have seat, by, put leg, couch, lifting, rotation, move the swivel chair of a series of functions.

The technical solution of the utility model is: a kind of multifunctional rotating chair, form by backrest, handrail, seat body, lowering or hoisting gear, runners, lowering or hoisting gear is installed on the runners, an adjustable housing is fixed on lowering or hoisting gear top, adjustable housing respectively with backrest, the seat body hinged, the adjustable housing front end is provided with leg rest, and backrest, adjustable housing, leg rest are formed a trace mechanism.

Adjustable housing is made up of be hinged interlock and the big extension spring of several shaped pieces, have two groups of identical lower ends that present body is installed with the direction of mutual correspondence of structure, one rectangular tube passes the shaped piece at the place, equilbrium position of adjustable housing and fixes with the bending member that has square opening, two groups of adjustable housings link by the rectangular tube connection, and whole adjustable housing is an equalization point with the rectangular tube central point.

Lowering or hoisting gear top has carriage, and the underframe of carriage and adjustable housing is fixed.

Rectangular tube one end of two groups of adjustable housings of interlock stretches out frame, and external part inserts one handle, is used for the manual frame of opening.

The utlity model has seat, put leg, function such as couch, rotate, move, when swivel chair is put, leg cushion is pushed away inward and can draw in, volume is little, and the people can just sit in the above.When needing, pull the unlatching hand-control device that is installed on a body one side, leg cushion is upspring with adjustable housing by time rest, alleviating fatigue, as the rest of wanting to lie down, the center of gravity of upper body can be pressed backward, backrest will tilt along with moving after the center of gravity, up to feel comfortable till; As think slightly to raise upper body, backrest also can be raised along with the rising of human body, reaches the function of deform in same pace fully.Can realize rotating and elevating function runners band universal wheel, conveniently moving by lowering or hoisting gear.

Below in conjunction with drawings and Examples the utility model is further described.

Structural representation when Fig. 1 is the utility model rounding state;

Structural representation when Fig. 2 puts the leg open mode for the utility model;

Adjustable housing inside structure schematic diagram when Fig. 3 couches state for the utility model;

Fig. 3 is the utility model frame hand-control device work schematic diagram.

As figure, the utility model is by backrest 1, handrail 2, seat body 3, lowering or hoisting gear 5, runners 6, and lowering or hoisting gear 5 is installed on the runners 6, and lowering or hoisting gear 5 tops are fixing with adjustable housing 7, and adjustable housing 7 is hinged with backrest 1, a body 3 respectively.

On the seat body 3 seat cushion 9 is arranged, skirtboard 8 is equipped with in both sides, damages and beautify the effect of moulding to prevent children's curiosity from hand is put in frame.

Adjustable housing 7 front ends are provided with leg rest 4, and backrest 1, adjustable housing 7, leg rest 4 are formed a trace mechanism, and each shaped piece rotates and balance by lever principle, and adjustable housing 7 is out of shape along the equalization point of frame.

Adjustable housing 7 is made up of be hinged interlock and the big extension spring 10 of several shaped pieces, the shaped piece 71 of adjustable housing 7 is bending shape, one end and backrest 1 are fixing, the bending place and the other end are hinged with shaped piece 72 and shaped piece 74 respectively, the central part that seat body 3 is fixed in whole adjustable housing 7 is on the shaped piece 75, shaped piece 77 on the adjustable housing 7 has a projection bent over arms 79, and the arm end connects big extension spring 10, and the other end of big extension spring 10 and the shaped piece of adjustable housing 7 front ends 80 are fixing.

Adjustable housing 7 front ends be hinged shaped piece 80, shaped piece 81, shaped piece 82, shaped piece 83, shaped piece 84, fixture 85, form a leg rest 4, Convenient table pad 20 on the fixture 85 is formed and is put leg device, leg pad 20 can clockwise rotate, the whole leg device of putting can rotate, draw in around pin joint, by the effect of big extension spring 10 and hinged shaped piece, can be in same plane with seat cushion 9 when putting leg device and upspringing.

The shaped piece 73 of adjustable housing 7, shaped piece 78 and underframe 13 are hinged, and underframe 13 is fixing by the carriage on angle steel and the lowering or hoisting gear 5 14.

Adjustable housing 7 has identical two groups of structure, be installed in seat body 3 both sides of swivel chair respectively relatively, the equilbrium position that one rectangular tube 12 passes adjustable housing 7 is that shaped piece 75 is fixing with shaped piece 76, two adjustable frames connect by rectangular tube 12, cooperate with square hole on the shaped piece 75 and link by rectangular tube 12, rectangular tube 12 central points are the equalization point of whole adjustable housing, are 0 point.

As Fig. 4, rectangular tube 12 1 ends stretch out the shaped piece 76 of adjustable housing, insert handle 11 on the external part, and shaped piece 76 is hinged with shaped piece 77, and pin joint is the A point.Bent over arms 79 is the B point with big extension spring 10 tie points on the shaped piece 77.

Pull handle 11, rotate rectangular tube 12, the link position that point of A shown in the figure and B are ordered is lower than 0 point, promote shaped piece 77, because the active force of human body and the effect of spring, each shaped piece of leg rest is formed in promotion, and adjustable housing 7 is opened, put leg device 4 and upspring, finish by sitting posture and be changed to the action of lifting pin.During gathering, rotate the bending leg cushion and push away inward, promote shaped piece 77, A point is raised, when the link position of ordering as the point of A shown in the figure and B was higher than at 0, rectangular tube 12 rotations made whole adjustable housing 7 be in the equilbrium position, adjustable housing 7 self-lockings.
