Description

A kind of chair

Technical field

The present invention relates to wood furniture manufacture field, specifically a kind of chair.

Background technology

Existing chair is the structure that regulation is highly typically with in Fig. 1, including seat 1 and two chair lower limbs 2, Two chair lower limbs are arranged on seat both sides, and chair inboard leg has been horizontally disposed with multiple screens groove 5 along chair leg length direction, makes Seat is snapped in the groove that two handrails are corresponding by the used time, needs to be extracted out by seat during regulation height, card again Enter in different grooves.Although the chair of this structure can regulate height, very inconvenience, need to by seat with The chair back just can regulate after separating, and cannot fold.

The Chinese invention patent of Application No. 201310322919.8 discloses a kind of folding seat, it include backrest, If seat and dry support arm；Described support member includes the articulated elements one being connected on backrest, articulated elements one from By end connecting hinge fitting two, the upper end of articulated elements two connects a quadric chain；Described quadric chain includes Backrest and the hinged seat of articulated elements two, the support member one supporting seat and one end are hinged on backrest, another One end is hinged on the standing surface on seat；Described support member one one end and seat, articulated elements two form concurrent hinge Connecing, the other end and backrest are hinged；It is hinged with on described articulated elements two and the articulated elements three of its formation fork configuration, Described articulated elements three one end is hinged on backrest, and the other end supports on the ground；Described each parts and backrest are even The pin joint connect is fixing pin joint, and other is moveable hinge contact.

Summary of the invention

The technical problem to be solved is: provide a kind of height adjustable and foldable chair.

In order to solve above-mentioned technical problem, the technical solution used in the present invention is: a kind of chair, including seat With two chair lower limbs, two chair lower limbs are separately positioned on the both sides of seat, and leg includes the first support bar, and described One support bar is angled with ground to be arranged；

The inner side of described first support bar is provided with multiple first groove, often along the length direction of the first support bar Being provided with the second groove between two the first grooves, described second groove and the first groove communicate, and described second Groove is rectangle, and described first groove includes two fan grooves communicated with each other, and two fan grooves become 180 degree to set Put, between two fan grooves, be provided with screens step；

The both sides of described seat are provided with projection, and described projection can be rotatably set in the first groove, and described The width of two grooves is more than the thickness of projection.

The beneficial effects of the present invention is: the first groove and the second groove are set on chair lower limb so that seat Projection can be at the first groove internal rotation angle degree, and when projection rotates at screens step, the height of seat obtains Fixing；When needs adjust seat height, the projection of seat is rotated to aliging with the second groove, then edge In the first groove that the projection of seat is moved on to desired height by the second groove, by seat when chair leaves unused Projection stay in the second groove, seat can be made parallel with first spike place plane, thus reduce Chair take volume, and without seat is extracted out from chair lower limb when folding, simple to operate, even child Can also complete independently.
