CN2219634Y - Synchronous automatic elastic multifunctional chair - Google Patents

Abstract

The utility model relates to a synchronous automatic elastic chair with a short backrest. A pneumatic cylinder acts on liftingof the chair and reclining of the backrest. The utility model fully utilizes the acting force of the pneumatic cylinder, synchronously realizes four automatic functions with different uses. Firstly, the short backrest arranged under shoulders can be automatically extended and heightened to a head part when the chair is reclined, and can also be automatically shortened and lowered down. Secondly, a massage footstool and a wane leg stool have the functions of automatic expansion, contraction and lifting operation. Thirdly, a backward leg stretching device arranged under the seat automatically extends out of the chair to support the barycenter when the chair back is reclined and the barycenter is backwards offset. Fourthly, the lying angle is from 120 DEG to 174 DEG, and the length is from 0.70 meters to 1.800 meters, so an optimum rest state is achieved.

Description

Automatically flexible synchronously multifunction seat

The utility model relates to a kind of seat that Pneumatic cylinder device is arranged of furniture.

At present, existing Pneumatic cylinder device seat mainly acts on the height lifting, and backrest angle is swayed.The seat that class is higher, as Japan, Germany, the U.S. etc. be only increased foot pad and lean forward after shake and massage functions.Several functions that increase are not only all irrelevant with the effect of pneumatic cylinder, and need in two steps or the operation of three steps could realize above-mentioned functions, and promptly a step is the height lifting, and two go on foot to swaying angle, and three go on foot to stretching out or the perk foot pad.And the seat with the angle function of swaying, backrest height is all equally matched or exceed the crown with height of head, not only obstruct the view, and it is inharmonious with indoor layout atmosphere style, in recent years the good short backrest seat of external trend, when but short backrest is swung back with the angle of swaying, cause the head hindbrain unsettled again, can't coordinate to use.In addition, the angle of swaying is big more, and center of gravity is offset also big more backward, loses center of gravity easily and topples over backward, and for addressing this problem, Japan, Germany etc. only increase a fixed support or prolongation framework and handrail in the seat back length solves the supporting gravity problem.

The purpose of this utility model be to provide function more complete, use simpler.Make full use of the active force of pneumatic cylinder, it is short to design backrest on the basis of Pneumatic cylinder device, has step congenerous and automatic extending-contracting apparatus, only needs to handle a handrail switch, just can settle the not automatic function of same-action of four kinds of synchronous realizations at one go.

The purpose of this utility model is achieved in that at the armrest position a steel wire gate wrench, is used for the switch of pneumatic cylinder, when handling wrench, short back recline angle, every to layback once short backrest made progress long one minute, and the angle of swaying is big more, short backrest will be got over Gao Yuechang, the short backrest that is positioned at below the shoulder is extended automatically increase to head, to the backrest top, horizontal total length reaches 1.80 meters from leg massaging chair, whole body is unfolded, reach best resting state.Otherwise when backrest rose forward, backrest also can shorten reduction automatically and be reduced to short back rest shape.When stating automatic function in realization, produced the function of seesaw leg stool and leg massaging chair again, the former automatic perk is landed; The latter stretches out the seat of two kinds of different class of withdrawal automatically, seesaw leg stool is identical with leg massaging chair automatic function principle, structure is different with effect, and both differences are that seesaw leg stool is the shank pad to be risen horizontal, and the effect of leg massaging chair is that the both feet pad is risen and massages.When stating three kinds of automatic functions in realization, produced the 4th kind of synchronous automatic function again, the device of stretching one's legs promptly, this device is intended mutually with the telescopic arm structure of leg massaging chair, mainly acts on the chair back and sways center of gravity when being offset backward, after stretch one's legs and stretch out supporting gravity automatically, prevent that seat from toppling over backward because of losing center of gravity, when the chair back rises forward, after the withdrawal automatically of stretching one's legs, couch 120 °-174 ° of angles of arbitrary stepless, the length that couches 0.7-1.80 rice.Above-mentioned all automatic functions all have indivisible substantial connection with the pneumatic cylinder active force, just can Synchronization Control by a handle switch.

The concrete structure of utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the static half-sectional view of the utility model A type (seesaw leg stool).

Fig. 2 is that the utility model A type is along the dynamic half-sectional view of the automatic function of direction shown in the arrow.

Fig. 3 is the static half-sectional view of the utility model Type B (leg massaging chair).

Fig. 4 is that the utility model Type B is along the dynamic half-sectional view of the automatic function of direction shown in the arrow.

Fig. 5 is the dynamic half-sectional view of the utility model Type B telescopic arm automatic function.

Below in conjunction with details and the working condition of accompanying drawing detailed description according to the concrete device that the utility model proposes.

The described A type of Fig. 1 seat seesaw leg stool (1) is connected with expansion link (2), and expansion link (2) other end is connected with pneumatic cylinder support (6), pneumatic cylinder support (6) other end is connected with pneumatic cylinder (4), simultaneously again with after stretch one's legs (5) is connected, after the stretch one's legs other end and the backrest rail rods (7) of (5) fix.Backrest rail rods (7) is communicated with the backrests that are divided into three joints, and backrest and rail rods are established two fulcrums respectively, and an axle center is respectively arranged, and backrest height heave amplitude size depends between two axle center that at a distance of what, at a distance of big more, high low amplitude is also big more, otherwise just more little.And be connected with seat frame.Type B leg massaging chair (8) is identical with A type seesaw leg stool (1) operation principle, and structure is different with effect.Massage roller (9) is connected with leg massaging chair (8), and telescopic arm (10) is connected with leg massaging chair (8), the other end with after stretch one's legs (5) be connected.Next the otherwise structure of Type B and the effect all basic identical with the A type, telescopic arm (10) or expansion link (2) and after stretch one's legs (5) be fastened on same axostylus axostyle.Complete, multi-functional, synchronous automatic system have been formed.

This automatic system is work like this: actuating steel wire gate wrench (3), utilize the active force of health to layback, and at first, the short backrest that is divided into three joints, is increased along backrest rail rods (7) elongation shown in dynamic accompanying drawing along direction shown in the arrow; Secondly, active force by pneumatic cylinder support (6) to pneumatic cylinder (4) when compressing, stretch one's legs after acting on again (5), and act on seesaw leg stool (1) or leg massaging chair (8) along expansion link (2) or telescopic arm (10), produced synchronous layback, increased, extended, stretched out and the perk automatic function.Otherwise when backrest rose forward, the active force that utilizes pneumatic cylinder (4) to produce along rightabout shown in the arrow, shown in dynamic accompanying drawing, had produced synchronous rise, reduction, shortening, withdrawal, the receipts automatic function that falls.
