Description
Technical field
The present invention relates to there is multisection type freely to adjust for the functional framework mechanism of a kind of sofa, chair, especially framework backrest
The functional frame of section.
Background technology
There is at present the sofa or chair for facing upward function of lying, its built-in frame mechanism generally comprises two parts, such as Fig. 1,2
Shown schematic diagram of the function, seat frame part 1, and seat frame part 1 are hinged rotatable back part 2.By adjusting seat frame and leaning on
Between the back of the body, the distance of application point rotates against seat frame portion and back part, reaches the regulation of angle between seat frame and backrest,
Realize the conversion of sofa, chair from sitting posture to lying posture.
When sofa, chair are in lying status, headrest position is also in horizontality with back part for this mechanism, this
Human body head is made just in uncomfortable state.This is directed to, for expanded function and the more preferable Consumer's Experience of acquisition, this kind of irony
The back part of frame mechanism is also divided into the pillow 21 of top half, and the backrest body 22 of the latter half, 21 He of pillow
Backrest body 22 is hinged.Additionally, also including a gangbar 23, one end of gangbar is fixed on seat frame part 1, and the other end is solid
It is scheduled on pillow, thus forms two groups of rotating mechanisms, i.e., with gangbar as swingle connecting seat frame portion point 1 and pillow
The first revolving rod.With the second revolving rod for dividing 1 and pillow with backrest body 22 as swingle connecting seat frame portion.Lean on
In back of the body rotary course, rotational angle of the gangbar rotational angle less than backrest body, so as to draw pillow lifting, realizes headrest
Linkage.
But which has the disadvantage：Headrest link mechanism is by increasing gangbar between head rest and seat frame, forming an envelope
The four-bar mechanism for closing, the angular adjustment of gangbar traction pillow is constant, it is impossible to realize random angle under headrest separate state
The regulation of degree.
Further, since gangbar one end is connected to head rest by revolute, the other end is present by revolute connection
Frame portion point, so, when actually making product, simply can not be dismantled between seat frame and backrest, it is necessary to dismantle pin or
The modes such as bolt are realized.Due to not easy to remove between seat frame and backrest so that sofa is necessary in virtual package, transportation
Both connections are remained, so as to the packaging volume for wasting, the cost and competitiveness of whole product is affected.
The content of the invention
It is an object of the invention to provide a kind of multisection type free regulation function frame, except between backrest and seat frame, angle is adjusted
Section is outer, while can also realize resting the head on regulation is rotated freely and backrest body between, it is ensured that sofa, chair cervical region when in use
A comfortable angle can be obtained.
The purpose of the present invention by following technical solution completing, multisection type free regulation function frame, including backrest

Instead, the ratchet in the profile of tooth slotted eye has three.
The frame bottom and rotor plate top are respectively formed with the grafting body of rod of projection, the grafting body of rod and headrest bone
The body of rod socket of frame.
The unidirectional limit hinge is thousand layers of hinge of disc type, and thousand layers of hinge include disc type position-limit mechanism, and are fixed on
First linking arm and the second linking arm at disc type position-limit mechanism two ends, first linking arm and the second linking arm are fixed on headrest
On skeleton.
The gangbar group includes the first rod member, the second rod member and the 3rd rod member being hinged successively, and the first rod member is fixed on
Back rest, the 3rd rod member are fixed on pillow；T-connecting piece is additionally provided between first rod member and the second rod member, the company
There is fitting first end and the second end, first end and the second end to be hinged with the first rod member and the second rod member respectively, and the T-shaped connects
Part also has inserted terminal, and the base skeleton is formed with the groove portion with T-connecting piece inserted terminal grafting.
First rod member is fixed on back rest, and the 3rd rod member is fixed between head pillow frame and backrest frames pin joint
Place.
The base assembly also includes driving extending apparatus, the stretching, extension first end of the extending apparatus connect base component and leans on
Second end of stretching, extension of back of the body component.
The present invention makes backrest into three-stage by original two-part, i.e., the headrest top of unidirectional limit hinge connection is single
Stage casing between limit hinge and lower back frame, and lower back frame, stage casing and headrest top pass through unidirectional hinge certainly
Adjusted by rotation, stage casing and lower back frame are adjusted by gangbar rotation, so as to realize the three-stage adjustable angle of backrest, symbol
Close ergonomics to require, increase the comfortableness of sofa.
Meanwhile, being connected by gangbar group between backrest module and base assembly, i.e., backrest module is inserted by T-connecting piece
It is connected on base assembly, while realizing backrest module and base group by being hinged for the first rod member, the second rod member and T-connecting piece
Part is hinged, and such base can be connected by way of inserted sheet with back part, it is achieved thereby that the dismounting side of plug and play
Formula, saved by functional frame produce finished product chair, the dismounting of sofa, cost of transportation, improve the competitiveness of product.
