Description

Tool is hidden the office chair of switch

Technical field

The utility model relates to a kind of office chair, refers in particular to the office chair that a kind of tool is hidden switch.

Background technology

Have the office chair of adjusting function and be subjected to user's favorable comment deeply, to adjust function before and after the chair back of office chair be more rare and have.

With reference to Figure 25, be a kind of schematic diagram of back-rest means for chair of current chairs.It has disclosed the function of adjusting before and after the chair back, and it includes: seat and the backrest in the rear end of this seat on pillar that is connected to the chair leg.This backrest comprises back of the body frame, back bar and a back board module.By the back bar is installed to a mounting portion, this backrest is locked to this seat.This backrest is can be forward after being adjusted in position and downwards, perhaps backward and move up.This backrest is by reduction of area behind this seat of weight dealing of passenger.This backrest is to move with respect to this seat, and forward with downwards, to such an extent as to this backrest that perhaps slides backward and upwards is to be adjusted in position to meet the build of passenger.This mounting portion comprises a pedestal that is fixed to the lower surface of this seat; One at the lower surface of this seat and the engagement component between this pedestal; With one be used for this engagement component is moved up and down running assembly.This running assembly utilizes the mode of screw lock to adjust, and this running assembly exposes to this seat and this back joint, and running assembly is positioned at this position allows the user walk about in the rear of chair and false touch or bump easily, and gives the doubt on people's safety.In addition, the running assembly that exposes is also given a kind of laxative design of people, thereby the necessity that is improved is arranged.

The common adjustment function of office chair is lifting and reclining adjustment in addition, and therefore it obtain liking of occupant deeply because can provide the occupant to adjust voluntarily at different figures and different situations.At present common have an office chair of adjusting function, and it is adjusted switch and all exposes to office chair, and forms the shaft-like of evagination, when occupant during at office chair, utilizes the adjusting lever that its hand gropes to expose and the action of adjusting.

With reference to Figure 26, be a kind of schematic diagram of chassis structure of existing office chair.It includes: a seat cushion underframe and a fixed pedestal, the seat cushion underframe has two groups of knot bars, and this group knot bar two side ends upwards is bent to form pivoting part, and the vertical welding in two ends of two groups of knot bar bottom sides is provided with two mutual parallel slide rails, this two slide rail has a slideway for slide displacement, the outer side edges of one wood side-guide runs through group and is provided with a stopper, fixed pedestal is for being mounted on the foot rest extension rod, its dual-side forms sliding part respectively, and this sliding part two outboard ends cooperate slideway respectively to be arranged with slide block, and the sliding part between two slide blocks and be concaved with several block short slot persons; The seat cushion underframe is with the combination setting of group knot bar both sides pivoting part for seat support, and this seat cushion underframe is arranged on the fixed pedestal by two wood side-guides, and be placed on the both sides slideway on the slide block of both sides sliding part, stopper then is arranged in the block short slot limit of sliding part relatively, and this stopper clip is in a block short slot of sliding part.

When user's desire is adjusted the relative position of seat and fixed pedestal, the bar that leans on the slide rail side stopper is pulled back and pulls, make the block short slot that end breaks away from sliding part that leans that leans bar, in order to do can be with seat cushion underframe slide displacement on the sliding part of fixed pedestal, to adjust the relative position between seat cushion and fixed pedestal, and then will lean bar and loosen it is rebounded toward the slideway place by elastic component, and to lean the end clip in a block short slot of sliding part, by above-mentioned start, just can finish the recurrence relation that it adjusts start.

The above-mentioned bar that leans is shaft-like and exposes to the seat cushion underframe, the occupant is by pulling the purpose that leans bar and reach adjustment, and the bar that leans that exposes has the possibility of accidentally injuring the occupant, when the occupant desires to take near seat, the occupant may collide and lean bar, and gives the doubt on people's safety.In addition, the bar that leans that exposes is also given a kind of laxative design of people.

Therefore, the utility model problem of wanting to get rid of or alleviating prior art at least and met with.

The utility model content

The technical problem that the utility model institute desire solves is the disappearance at the prior art existence, provides a kind of tool to hide the office chair of switch.

The technological means that the utility model is mainly improved is, provides a kind of tool to hide the office chair of switch, and it includes: a foot rest, its two ends are respectively a support end and a binding end, and this support end can be supported in ground; A seat frame, it accepts this binding end; A back rest, it comprises one first framework and one second framework, and this first framework comprises first end and second end, and this first framework, first end is incorporated into this seat frame; A backrest adjusting device, it connects this first framework and this second framework, this backrest adjusting device comprises one first switch, this first switch is between this first framework and this second framework, make this first switch reach concealment effect, this first switch can adjusted switching change between position and the position location, and this first switch is positioned at when adjusting the position, and this second framework can move relative to this first framework; When this first switch was positioned at the position location, this second framework and this first framework formed the location.
