Description
Technical field
The utility model relates to field of sanitary equipment, particularly relates to a kind of multifunction seat.
Background technology
Existing seat is more and more valued for the design of its comfortableness, and therefore more existing seats can have one or more in following structure, comprise can adjust up and down headrest, adjustable-angle the chair back and the foot-mat mechanism of foot's shank position can be provided support.But with regard to the foot-mat mechanism of existing seat, it has the weak point of two aspects at least: 1, and existing foot-mat mechanism generally can be designed to and chair back interlock, and namely during chair back layback, this foot pad can synchronous expansion, but when this kind of design will cause the chair back not swing back, foot pad can not launch, and applicability is not strong; 2, existing foot-mat mechanism fold poor effect, namely under collapse state for use comfortableness produce certain influence.
And the weak point that existing chair back adjustable seat exists is: when the chair back of seat regulates backward, whole past for the meeting of the center of gravity of chair rear-inclined, when between the chair back and seat support, angle is excessive, user lies on the back and is easy on the seat make seat overturning backward, and namely the stationarity of seat is not high exists potential safety hazard.
The weak point that the seat of the existing headrest that can adjust up and down exists then is divided into two kinds of situations: a kind of situation such as publication number is disclose a kind of height of headrest regulative mode in the Chinese patent of CN201718807U, be that headrest lower end is provided with oval elongated hole, resting the head on is connected with described backboard by screw by the oval elongated hole of its lower end; But which structure simple, with low cost headrest adjustment process relative complex; Another kind of situation such as publication number is disclose another kind of height of headrest regulative mode in the Chinese patent of CN103287297A, and carry out up-down adjustment by the height of driven by motor worm screw to headrest, this structure makes headrest easy to adjust; But problem part is: headrest adjusting structure is too complicated, and manufacturing cost is too high, and there is potential safety hazard in motor driving.
In addition, existing seat all adopts mechanical switch, with the form of physical mechanical, path is reached the state of Push And Release, as the running water halter in the toggle switch of bulb in family, ordinary people family, namely mechanical switch is manipulated by pure frame for movement; But the deficiency that the mechanical switch on existing seat exists is, mechanical switch generally only has a road to export, function singleness.
For now, also can solve above-mentioned all technical problems without any a seat simultaneously.
Summary of the invention
In order to solve the problem, the first object of the present utility model is the multifunction seat providing a kind of novel structure, and this multifunction seat at least can independently control the ejection of foot pad or fold; Second object of the present utility model is the improvement providing a kind of back regulating mechanism to this multifunction seat; 3rd object of the present utility model is the improvement providing a kind of headrest lifting structure for multifunction seat; 4th object of the present utility model is to provide a kind of novel structure, has three control switches of three tunnels outputs.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of multifunction seat, comprises seat support and is fixed on foot pad, foot pad locker and the foot pad device for ejecting on seat support; Described foot pad device for ejecting comprises the hollow tube be fixed on seat support lower surface, and is movably arranged on the movable axis in hollow tube, and the outer end of movable axis is hinged on foot pad; Described foot pad locker comprises the snap close seat be fixed on seat support lower surface and the locking board being fixed on foot pad rear end face, and snap close seat comprises housing and the mobile lock pin base plate be arranged in housing, and the stage clip be arranged on lock pin base plate and two pieces of lock pin blocks; Lock pin base plate is at least provided with two chutes, two chutes tilt, arrange in opposite directions, and two pieces of lock pin blocks are slidably arranged in two chutes respectively, and the outer end of lock pin block is located in the outside of housing, and stage clip is arranged between two pieces of lock pin block inner ends; Described locking board is provided with the lock pin groove matched with the outer end of lock pin block.
As preferably, be also provided with stage clip in described hollow tube, the rearward end of hollow tube is closed, and stage clip is between the inner end of movable axis and the rearward end of hollow tube; Stage clip is in compressive state, when the foot pad of movable axis outer end is not lived by snap close, drives the foot pad of movable axis and outer end thereof to eject by stage clip.
As preferably, the outer end of described movable axis is provided with threeway connector, and foot pad is provided with the clamping seat for snapping in threeway connector, threeway connector by hinge on clamping seat; Be provided with reduction torsion spring between described threeway connector and clamping seat, the axis client of reduction torsion spring is fixed in threeway connector, and outer end and the clamping seat of reduction torsion spring offset.The turnover of foot pad is realized, specifically: when foot pad is pinned by foot pad locker, reduction torsion spring is in deformation state by reduction torsion spring; When foot pad locker unclamps, reduction torsion spring restores the elastic force produced to promote foot pad turnover, launches.
As preferably, also comprise base, the chair back and armrest seat; The lower end of described armrest seat is fixed on base, and the middle part of the chair back is hinged on armrest seat, the bottom of the chair back by hinge in the rearward end of seat support; The lower end of described seat support is connected with armrest seat by chair base connecting device, chair base connecting device comprises the deck being fixed on armrest seat lower surface and the U-rail be fixed on seat support lower surface, be provided with hole clipping and the stopping means for limiting U-rail in deck, U-rail to be located in hole clipping and to be connected with described stopping means.When wanting adjusting seat angle, needing to apply external force to stopping means, making stopping means remove for the restriction of U-rail, seat support by U-rail along deck be leverage points can before and after regulate, when seat support moves forward, seat support front end upwarps, and turns under the chair back; Overall chair realizes backrest and seat support links, and comfort is good; And while turning under the chair back, seat support need move forward, only there is very little change in location in the seat center of gravity after expansion, and therefore, the stationarity of seat is high, not prone to tip over.
As preferably, described hole clipping runs through the front and back end of deck, the limit pin hole communicated with hole clipping in deck, stopping means comprises and is arranged on spacer pin in limit pin hole and stage clip, described U-rail is provided with multiple bearing pin buckling groove, the outer end of spacer pin to snap in hole clipping and offsets with one of them the bearing pin buckling groove on U-rail, and inner end and the stage clip of spacer pin offset.Namely by the movement of spacer pin restriction U-rail in the hole clipping of deck, stablize whole seat; When needs adjusting seat angle, spacer pin can be pulled by external force, remove spacer pin for the restriction of U-rail, after chair angle has adjusted, remove external force, made spacer pin again limit U-rail by stage clip elastic force.
