Description

Folding seat

Technical field

The utility model relates to a kind of household articles or tourism supplies, particularly a kind of folding seat.

Background technology

Folding seat, since invention, because its structure is light, can stack, has been convenient to move and take in, and has obtained liking of people, and from picnic barbecue, recreational fishing to life staying idle at home, folding seat obtains a wide range of applications.The structure of folding seat is also constantly being improved, and from initial simple and easy campstool, Armrest by now, with the seat series of backrest.In comfort level, security aspect has obtained great lifting.

Conventional folding seat, its seat support and armrest portion all adopt fabric to make.Because folding needs, handrail has adopted flexible material to connect handrail two ends.People are sitting in the folding seat of opening, and soft cloth handrail can be bent downwardly distortion owing to being subject to the pressure of arm, causes the front and back of chair to be shunk to centre, make people produce a kind of sensation of depression, and the after sensation of sitting down is also uncomfortable.

For addressing this problem, the personnel in seat design field design the folding seat of hard structure, and as patent No. CN201220694184.2 " a kind of folding seat ", it has adopted four cross-coupled contraction understructures, and backrest has adopted a pair of vertical rod to support.One end of armrest has adopted the structure of sliding in vertical rod, and has adopted locking stifle to fix, and the other end of handrail, has adopted folding rod structure, and the bottom of folding rod is supported on the front end connection that shrinks base.

The folding seat of this structure, people are sitting in folding seat, still also uncomfortable.From its structure, four connectors of the dependence of its seat support contraction base are fixed, and people are sitting in folding seat, still can produce depression, cause the contraction base of four intersections inwardly to shrink, and make people produce the sensation of depression.The front end of the handrail place that normally arm is placed in addition, because the bottom of folding rod is only supported on connector, and does not land, and folding rod itself has certain elasticity, causes handrail front end easily to lean forward, and causes folding seat unstable.

Summary of the invention

Technical problem to be solved in the utility model: a kind of folding seat with hard handrail is provided, stabilized structure, folding convenient, comfort level are good.

The technical scheme in the invention for solving the above technical problem is: a kind of folding seat, comprise seat and support that fabric is made, seat webbing is connected on support, it is characterized in that: about described support comprises, the pair of brackets body of symmetry connects by two pairs of front and back crossbar each other; Described stake body comprises that back support bar, front support rod, rear support leg, seat support bar, handrail are formed by connecting by connector; Described front support rod is expansion link, outer bar and the interior bar that is socketed in outer bar inside, consists of, and the bottom of interior bar is fixedly connected with station pin, and the top of outer bar is connected by adaptor with the bottom of handrail.

Described connector comprises the first connector, the second connector and the 3rd connector, and adaptor.

Described the first connector is U font, and a horizontal rotating shaft, through the connecting hole of both sides, is rotationally connected the bottom of the bottom of back support bar, front support rod; One vertical rotating shaft is through the hinge hole of the first connector bottom, by the first connector and front crossbar bottom-hinged.

Described the 3rd connector is strip, and centre is groove, and this groove coordinates with back support bar, and is rotationally connected by top and the back support bar of groove, and one end of groove is jagged, and the rear end of the other end and handrail is rotationally connected.

Described the second connector is L-type, on the second connector, there are four installing holes, wherein on two arms, respectively there are two installing holes, the upper end of rear support pin is fixedly connected with the 3rd installing hole and the 4th installing hole on the second connector, the middle part of back support bar and the second installing hole are rotationally connected, and one end of seat support bar and the first installing hole are rotationally connected.

Two arm angles of described the second connector are 135 degree.

Compared with prior art, the utility model has the advantage of: back support bar adopts inclined design, and handrail is hard, and retained appropriate radian design, meet ergonomics design, use comfortablely, the front support rod that passes through of handrail contacts with ground, stabilized structure; Seat adopts the aluminium-alloy pipe of pair of parallel to support, and resistance to deformation is effective, does not produce depression sense.
