Description

A kind of chair frame of scalable position of back
Technical field
The present invention relates to chair, especially relate to a kind of chair frame that is mainly used in the scalable position of back of couch or massage armchair.
Background technology
Prior health is with massage armchair (or couch is used in leisure); Generally can only regulate the inclination angle of backrest; There is distinct disadvantage in such structure: because massage armchair (or couch) floor space is bigger, normally to depend on wall to put on chair, therefore to work as human body for more comfortable or in order massaging better; Just need to regulate sitting posture; Then need regulate the inclination angle of back and the position at seat and change position of centre of gravity, stop, can't realize tilt function but the backrest of existing Chair structure often receives wall; And seat portion generally all is fixed, even the inclination angle of back changes, but because a seat location can not correspondingly change, and the human feeling is still undesirable, the massage position also is restricted.Like the patent No. is that the structure of the disclosed adjusting backrest inclination of the United States Patent (USP) degree of US5345626 does, the guide rail that is provided with on the seat support matches with the cam of backrest, realizes the adjusting to the gradient of backrest by the bracing frame at rear portion.And for example publication number is the disclosed electric back chair of Japan Patent of JP2002-017494, transmission mechanism such as push rod and so on, and rotation is connected in the end of back, and backrest connects with the mounting rotation, realizes regulating the backrest inclination degree.Above structure can find out, connects with guiding mechanism through rotation and just realized regulating the gradient of backrest, but can not realize the moving of relative position between seat and the backrest.And publication number to be the one Chinese patent application of CN101415581 disclose a kind of seat assembly for vehicles, it comprises the backrest that can between first upright position and second upright position in the front upper place of this first upright position, move.This seat-assembly has the guide assembly that provides front and back to regulate.This seat assembly for vehicles also comprises at least one pivot assembly, but this pivot assembly is attached to guide assembly with mode of operation, and is mounted to the floor of motor vehicle pivotly.Pivot assembly is at this seat assembly for vehicles that pivots between position and the stand up position of taking one's seat.Stand-up link is slidingly connected pivot assembly and backrest.The link lock locking is so that generate rigid attachment between pivot assembly and backrest.Along with seat assembly for vehicles moves taking one's seat between position and the stand up position, this rigid attachment guides this backrest between first upright position and second upright position.Above structure though realized moving forward and backward through guide rail and pivot structure, is merely the seat and moves forward and backward with backrest, and the backrest relative position moves forward and backward when can not realize regulating backrest angle.
Summary of the invention
For solving the deficiency of above technology, the purpose of this invention is to provide a kind ofly not only when the back rest inclination angle changes, can realize backrest with respect to the reach of seat frame position, and the chair frame of scalable position of back simple in structure, easy to use.
The present invention is provided with track base, back rest, seat frame and drive unit; Said track base is provided with base, 1 pair of horizontal guide rail and 1 pair of arc-shaped guide rail, and 1 pair of horizontal guide rail and 1 pair of equal left-right symmetric of arc-shaped guide rail are located on the base, and arc-shaped guide rail is positioned at the horizontal guide rail below;
Said back rest bottom cooperates with the arc-shaped guide rail of track base is movable, and the bottom and the seat frame of back rest are rotationally connected;
Said seat frame cooperates with horizontal guide rail is movable;
Said drive unit and seat frame are connected.
Said arc-shaped guide rail preferably by after be the shape that upwarps gradually forward, the front end that arc-shaped guide rail is upturned is connected on the lower side of horizontal guide rail.
The front end that said arc-shaped guide rail is upturned is connected on the horizontal guide rail lower side, and preferably the position that is connected on the horizontal guide rail lower side of the front end that is upturned of arc-shaped guide rail is the position apart from horizontal guide rail front end 1/3 horizontal guide rail length.
The a pair of horizontal guide rail of said track base preferably level is located at the base upper end.
The bottom of said back rest cooperates with the arc-shaped guide rail of track base is movable, and preferably the both sides, bottom of back rest are equipped with slide block, and slide block and arc-shaped guide rail are slidingly matched.
The bottom and the seat frame of said back rest are rotationally connected, and preferably the both sides, bottom of back rest are equipped with protruding axle, and correspondence is provided with protruding axle bed in both sides, seat frame rear end, and protruding axle is rotationally connected with protruding axle bed.
Said seat frame cooperates with horizontal guide rail is movable, and preferably the seat frame both sides are equipped with pulley, and pulley rolls with horizontal guide rail and cooperates.
Said drive unit preferably is provided with electric pushrod, rocking bar and connecting rod; Electric pushrod rear end and track base are hinged, and electric pushrod clutch end and rocking bar are hinged, and rocking bar one end and track base are hinged; The rocking bar other end and connecting rod one end are hinged, and the connecting rod other end and seat frame are hinged.Also be provided with hinged projection on the said rocking bar, hinged projection on the rocking bar and said electric pushrod clutch end are hinged.
The base of said track base is provided with front end support bar, intermediate supports bar, rear end upper support bar, rear end lower support bar, 8 montants and 2 side levers; 2 side levers are located at the bottom; Symmetry is established 4 montants on 2 side levers; The front end support bar is provided with hinged projection, and the intermediate supports bar is provided with hinged projection, and the hinged projection of said electric pushrod rear end and intermediate supports bar is hinged.
Operation principle of the present invention and beneficial effect are following: during use, when needs are regulated the back rest angle of inclination, start electric pushrod, electric pushrod drives rocking bar, and moves through connecting rod drive seat frame, and back rest is moved along horizontal guide rail and arc-shaped guide rail simultaneously.In whole back rest reach, because of being bent upwards of arc-shaped guide rail, making on the backrest bottom and lift, regulated the gradient of backrest, then the movement locus of the movement locus of back rest for not only tilting but also moving forward.This shows that back rest is not only tiltable but also can move forward not only, and seat frame moves forward synchronously.Place when chair leans on wall, when the adjusting backrest inclination is spent,, need not move chair, just can easily realize regulating backrest because of backrest can not take up room backward.Human body both can make the corresponding change of seat position again along with back rest tilt to change the angle of lying like this, thereby made the position of human center respective change and experience comfortable.In addition, for massage armchair, the massager core that is installed in back rest also can move up and down on a large scale, can realize being massaged into from the head buttocks and shank, improves massage effect greatly.Because track base, rocking bar, connecting rod and seat frame constitute lanar four rod mechanism, and drive through electric pushrod, so this mechanism is very simple, functional reliability is high.Only need control electric pushrod during use and start and stop, can realizing the regulation and control of back rest angle of inclination and seat frame reach position, use very convenient.
