Description

Inclinable surging sofa

The utility model is to belong to office, the dual-purpose chair of having a rest in the furniture.

As everyone knows, center of gravity dropped in the zone between back of thighs and the two ischium points when people were just sitting, and was to keep balance, and pin and shank also bear a part of strength.Just the seat time has been grown, and can feel that waist is tired, leg is tired, pin is tired.Just have and adjust the requirement that posture sets up, fixed chair then is restricted, and just can satisfy the demand and can face upward the chair that inclines.The couch of tilting-type has two kinds of patterns basically in prior art: a kind of is cycloid couch (rocking chair), as Fig. 2.The method that the human of seat changes position of centre of gravity can make the chair swing.Be characterized in that oscillating quantity is big, bad control when oscillating quantity is big makes the people that dizzy sensation be arranged.So advanced age, people and heart disease, hyperpietic should not use.Because of its floor space is big, profile is unbecoming again, in the restaurant, the bad furnishings of office; Another kind is exactly the simple and easy sofa that engage a gear is adjusted the elevation angle, and the adjustment that it faces upward degree of tilt is that stepping has level, faces upward when inclining lower leg portion is not settled, and people's gaskin of lying down hangs on ground, and the time has been grown also uncomfortable.

The design's purpose designs a chair for addressing the above problem, and can work when just sitting, and can adjust the elevation angle arbitrarily when tired, and it has the mechanism that holds up leg, with suitable angle shank is boosted when lying on the back, and for improving comfortableness, the design has increased wave mechanism again.

Tilting-type fluctuation couch (see figure 1) by back (1), cushion (6), handrail (2), hold up skirt (5) before the leg to form the four-bar mechanism of elevation-variable, the locking mechanism of forming four-bar mechanism by the locking nut (7) of the strut that has slotted hole (3), the threaded hinge axis of C point and band handle, whole chair is bearing on the O point of carrier base (8), elastic force undulator (4) is housed between carrier base and four-bar mechanism, the castor (9) of four direction-changeables is housed in carrier base bottom for conveniently moving.Elastic force undulator (Fig. 3) is made up of extension spring (10), stage clip (15) and interior overcoat (14), (16), and overcoat (16) seat is on carrier base, and pull bar (5) is contained on the handrail, and the strength of extension spring acts between pull bar and the overcoat.

When people just sat, the position of adjusting rod member also locked, and the center of gravity of people and chair slightly is prepended to supporting-point O, because the torque of the preposition formation of center of gravity, by elastic force undulator balance.At this moment the action of parts of body can make chair slight fluctuation occur.When sense of fatigue was arranged, releasable lock jack panel (7) with the strength of back, waist and shank, made the chair hypsokinesis to suitable angle, locking nut again when seat time just is long.The chair top rake can become with vertical plane between 15 °～60 ° to change.Because the effect of four-bar mechanism, with the hypsokinesis of the chair back, the front portion of cushion is lifted the hypomere of thigh gradually, holds up the preceding skirt of leg that shank is upwards boosted forward, and there is comfort at each position that makes health all with soft the contacting of suitable angle and sofa.When lying on the back, because the design of four-bar mechanism guarantees to make its center of gravity still slightly be prepended to supporting-point O, the trend of changeing before it is also by elastic force undulator balance.Some actions of head, arm, leg, pin when lying on the back, all centers of gravity that can make slightly change, and all can break original balance, and can cause the chair Pitching, and the number of times of fluctuation generally can reach 4～7 times.Because the effect of elastic force undulator, it can cause the chair fluctuation to small action, but it is to the excessive action and the damping action that fluctuateed.Because excessive fluctuation is not only uncomfortable, make the people dizzy on the contrary.Yet the wriggling friction that slight at a slow speed fluctuation makes human body and sofa respectively support the position is a kind of very gentle massage of closing, and can set up, and the comfort of height is arranged.If chair is placed quiet environment, the angle adjustment of lying on the back is suitable, after several slight fluctuations, and can be very fast sleeping.

Three kinds of embodiment of the total basic, normal, high shelves of the design: the one, the low-grade tilting-type static determinacy couch that does not have wave mechanism is as Fig. 4; The 2nd, tilting-type fluctuation couch, the characteristics of its structure and performance are as indicated above; The 3rd, tilting-type electric fluctuation couch.It replaces above-mentioned elastic force undulator with a power fluctuation device (as Fig. 5), and making chair obtain frequency is that 80 times/minute, amplitude are about 5～10 millimeters vibration.This is that human body is felt optimum frequency.Its vibration source is through the reductor rear drive wheel shaft (17) of slowing down by motor, eccentric Xiao Zi H shifting lever (18) on it, the swing of its lever is passed to handrail (2) by pull bar (19), and sleeve and stage clip (20) still are housed between handrail (2) and the carrier base (8).The time of vibration is by the torch gate control.6～8 electric massagers are adorned in the soft cover inside of skirt at backrest, cushion and before holding up leg, go control with corresponding electric switch, and Here it is also has the high-grade chair of medical functions concurrently except that having office, rest purposes.

The utility model has many good qualities compared with the prior art, and its low-grade chair is held up the front skirt of leg, can hold up shank, can choose the elevation angle wantonly; Its middle-grade fluctuation couch has wave mechanism, can give the soft massage of people with nature; High-grade electric fluctuation couch also has medical functions concurrently except possessing above-mentioned comfortableness. Add again the handsome in appearance of it, can claim it is the pattern of the complete design of a cover, practicality.

The experiment proved that the performance that reaches above-mentioned fully, take for a trial through many people, no matter height is fat or thin, As long as the position is sat rightly, the effect of same fluctuation is arranged.

Three kinds of embodiments of the design, structure is simpler and easy, all can make iron wood structure, is electroplated modification, and is handsome in appearance, and wide market is arranged. This expensive goods can be used on leader office, lobby, the lobby in hotel. Low-and-medium-grade products can be used on leader office, in the reception room in hotel, meeting room and the general family.
