Description

Bionics suspension sofa

The utility model relates to a kind of couch that produces the suspension pleasant effect, belongs to field of furniture.

Rocking chair of the prior art can make the seat, and the person is in swing state, and for a long time for people adopt, but human body is not to be in the little elastic movement state of damping.United States Patent (USP) 4372606, middle spike, the non-whole human body of disposed about spring ， Dan And is rocked together.

The purpose of this patent is a kind of couch with suspension pleasant effect that makes in the swing state that whole human body is in light and slow softness of design, and the vibrations that human body is subjected in vertical direction fundamentally solve the human comfort problem as possible for minimum.

Female tire effect theory is the theoretical foundation of this patent.This patent is thought: the root of human comfort sensation comes from human body and is suspended in sensation in the amniotic fluid of female tire at shaping stage.It is minimum that the wrinkle shape of human body is shaken in the amniotic fluid of female tire, but nonstatic, soft slowly rocks but be in, and the parcel that body is subjected to amniotic fluid is comforted with rubbing.Bionic theory in view of the above, seat design are answered shock-absorbing ， And to make the whole human body epidermis be subjected to soft to greatest extent contact ， And and whole human body are in soft slowly rock.The technical solution of the taproot of this patent is: use the seat face, long backrest and leg rest are connected and fixed the method that is integral and come the holding whole human body; And makes most weight of whole human body land by spike, makes it steady reality, shaken by the spring force vertical stress component.First kind embodiment spike can be single both feet and lands, use the support spring of contact carriage and human body supporting surface, in the dynamic equilibrium that whole human body is in slowly rock, generation is rocked back and forth, the second class embodiment spike can land by single single-point, front or use support spring that human body supporting surface multiaspect is rocked all around.The along slope coordinate of the run-on point of spike bottom all near the couch bottom, can increase slosh torque like this, adds the slosh torque of the leg rest that protracts, human light micromotion or breathing, and the human body supporting surface promptly produces and rocks, and the hypnosis medical functions is arranged.The lateral coordinates of run-on point is all near the gravity center of human body place, at this moment, the suffered power of support spring is smaller value, like this, the upright projection of the gravity tangential force that human body is subjected to, be that vertical vibration power is also less, rock then be the very little softness of damping slowly, and this has imitated soft shock-absorbing that female tire amniotic fluid risen and the comfortable function that rocks just.In addition, seat face, backrest and headrest should be made fossa shape, increase and the people contact level.

In addition, the supplementary technology solution of this patent is: the contact jaw in the spike run-on point is installed elasticity thing or electronic oscillator of the prior art, but must make the vibration energy in the per unit displacement reduce to minimum, the rigidity that is the elasticity thing should be little, the energy of concussion should be little, otherwise then lost the shock-absorbing effect of imitating female tire amniotic fluid.

This patent compared with prior art, feature is to be devoted to imitate female tire effect, makes it to produce the suspension pleasant effect.Thereby, compare with the rocking chair of prior art, be to have reduced damping and rigid holding, increased newly and rocked and suspension degree, do not exist together with the United States Patent (USP) of quoting as proof, be to make both feet place the whole human body supporting surface, human body integral rocks, and has got rid of the damping action that both feet land and risen, and run-on point moves down, leg rest protracts, and has increased slosh torque and degree of rocking.
