Description
[technical field]
The utility model belongs to field of furniture, more particularly, relates to a kind of multi-functional chair of sitting, lying, crouch.
[background technology]
The present seat of office, the chair back and seat are one, can not relative motion, only offer the function of people's seat; Though some leisure chaise longue has the function of partly lying, when the people swings back, move after the body's center of gravity, fall easily beyond the supporting surface, cause chair behind the people, to turn over.Aircraft business class chair can provide the function that crouches or partly lie, for fear of after turn over the base of taking usually chair and be fixed on the method (being equivalent to infinitely-great supporting surface) on the plate of cabin.This method obviously is not suitable for common seat.Can only lie prone at office worker's noon of office or night and on desk, have a rest momently, the rest of this posture is difficult to let the people obtain real recovery.
[utility model content]
The utility model technical problem to be solved is to provide a kind of simple in structure, safe, easy to use, many office chairs of use that can arbitrarily switch at seat, chaise longue, three kinds of states of bed, let the user can obtain the high-quality rest of short time.
The technical scheme of the utility model is: the multi-functional chair that can sit, lie, crouch; Comprise a chair back that constitutes by steel framework, back cushion; And the c-shaped chair frame in both sides that curves by a steel pipe, steel pipe middle part in said chair back both sides is hinged with the upper bend end of said C shape chair frame respectively; Steel pipe bottom, said chair back both sides and a rectangle seat board frame that has cushion are hinged, the hinged respectively arc strut that is equipped with of said seat board frame dual-side, said arc strut with in the said C shape chair frame lower hinge of homonymy; It is hinged that said seat board frame front end and has the knee torch of foot pad, and the said knee torch back side is hinged through push rod and steel pipe bottom, said chair back both sides; Be hinged with an attitude control lever in the middle of the said chair back bottom bar, a locking system is equipped with in said seat board frame bottom surface, and said locking system is sleeved on the said attitude control lever, is used to lock the angle of inclination of the said chair back and knee torch.
Further improvement as such scheme; Said locking system comprises a rotating shaft that is installed in said seat board frame bottom surface; On the said rotating shaft cam is housed; The rubber that the is used for fastening said attitude control lever skin of stopping is equipped with in the raised section of this cam outline, and rotary handle is equipped with in said rotating shaft outer end.
The principle of the utility model is: the utility model has utilized a plurality of planes four connecting rod principles, and seat back frame bottom, push rod, seat board frame and knee torch are hinged, and constitutes the double rocking lever four-bar mechanism, under external force freely deformable.The utility model initial position is the upright sitting posture of backboard (as shown in Figure 1), and this moment, system's center of gravity was in the bearing-surface that C shape chair is configured to; When the user unclamps locking system and topples over backward; The chair back under the effect of user's body weight hypsokinesis until flattening (as shown in Figure 2); With the knee torch of chair back interlock, seat board frame along the pin joint forward swing; Because the characteristic of double rocking lever four-bar mechanism, knee torch, stressed the moving with the chair back to the front upper place of seat board frame flush, and form bed; When the user sat up, knee torch is stressed to be put behind pin joint, and the seat board frame is stressed to be moved to the back lower place, and with the also stressed back of the seat back frame of knee torch interlock pendulum, the chair back recovers the sitting posture state.In this process, the seat center of gravity moves forward and backward with the seat board frame always, and seat launches fully or when recovering sitting posture, center of gravity drops in the C shape chair frame bearing-surface all the time, and the office chair whole machine balancing is kept, the problem that centre-of gravity shift can not take place and fall down.The arc strut has two effects, and the one, power-assisted is provided when being launched into bed for multi-functional chair, play the labour-saving effect, the 2nd, said double rocking lever four-bar mechanism is retrained, increase the stability of extreme position.
The advantage of the utility model is: the center of gravity shifting principle of having used a plurality of lanar four rod mechanisms; Do work through human body gravity; The completion handoff procedure that a little firmly can disequilibrate, system's center of gravity drops in the supporting surface all the time, makes the people can obtain safety, high-quality is had a rest; Slow down fatigue, help increasing work efficiency.
