Abstract

The utility model relates to a folding chair for killing time, which is characterized in that two pairs of movable fork shears are used to hinge left and right handrail racks to form a chair frame. The left part and the right part of the chair frame can be oppositely folded. A flexible face fabric surface is tensioned among upper transverse pipes connecting the two pairs of the movable fork shears to form the soft supporting seat surface in a horse rack type of the chair. The back upper parts of the left and right handrail racks are respectively provided with a backrest pipe which can vertically and horizontally turn. The flexible fabric surface is also tensioned between the two pipes to form the soft supporting backrest surface of the chair.

Description

Folding chair for kill time use

The utility model relates to a kind of soft supported folding chair.

Present various folding seat folds hard supporting construction before and after being basically.Bound below the seat of this class folding seat and the backrest during seat, human body and chair loading end anastomose property are poor with the rigid beam support, and contact area is little, and impetus is inhomogeneous, and the sitting meeting makes the people feel that boundary is hard, and is uncomfortable.

The purpose of this utility model is to bias toward portability at existing folding seat on design philosophy, and the deficiency of ignorance comfortableness, and the soft supporting construction that does not have rigid beam is adopted in a kind of bodily fuctions of the pressing design that proposes, light and comfortable taking into account, the folding seat of the sitting that is particularly suitable for lying fallow.

Technical characterictic of the present utility model: cut with two pairs of movable forks left and right arm-rest frame is articulated as one, lower end and arm-rest frame lower transverse tubule that fork is cut are hinged, pitch the stiff end hinge of cutting for activity, the upper end that fork is cut (movable end that movable fork is cut) is hinged with the axis hole end of frid, the detent ends of frid is hinged by slide bolt and the forward and backward column of arm-rest frame, constitute arm-rest frame and cut " fork is cut---frid swing mechanism " of interlock, form left and right sides doubling formula Chair frame with fork; Connecting two pairs of movable pitching between the upper lateral tube of cutting, the flexible fabric face that tacks down, the soft support seat surface of formation chair; On the backrest seat of left and right arm-rest frame back upper place, respectively be equipped with one and can make backing tube upright, flip horizontal, between two tubes, the flexible fabric face tacks down, constitute the soft support backrest face of chair, in the backing tube, be equipped with backing tube is pulled to the below, make backing tube be positioned the extension spring of upright or level.Cut when doing opening and closing campaign when pulling fork, be fixed on fork and cut motion that the seat surface on the upper lateral tube cuts movable end with fork and move from top to bottom and launch, or mobile from bottom to top folding; Simultaneously, the motion that left and right arm-rest frame is cut with fork by " fork is cut---frid swing mechanism " launches both sides to the left and right, or closes up to the centre, and drives that the backrest face launches or folding.The geometry of chair and yardstick are pressed the human body average dimension and are determined.

Advantage of the present utility model, be to adopt fork to cut the soft supporting construction of left and right sides doubling formula, the loading end of chair can match with the Human Physiology curve, and contact area is big, and impetus is even, have attractive appearance, light being suitable for, people's muscle ligament is in lax nature during seat, makes the people feel fit soft, easily, comfortable, have good casual health effect.

Below in conjunction with description of drawings embodiment:

Two pairs of movable forks are cut 2 upper end, connect with two upper lateral tubes 17, and the flexible fabric faces such as canvas, nylon tape that between two tubes, tack down, the seat surface 9 of formation chair saddle support minor.The lower end and lower transverse tubule 15 suits of left and right arm-rest frame 1,3 that activity fork is cut, and with the lining 14 of being with fixing spiral shell with its axial location, for fork is cut stiff end hinge 4; It is hinged with the axis hole of frid 6 that fork is cut movable end axle ear 5, and it is hinged slide bolt 8 to be passed the forward and backward column of chute 7 and arm-rest frame on the frid 15.13 again, constitutes arm-rest frame is cut interlock with fork " fork is cut---frid swing mechanism ".Slide bolt slides in the frid chute should be freely, and it should be fastening with being connected of the forward and backward column of arm-rest frame.Backing tube 12 groove hole ends are connected the flexible fabric faces such as canvas, nylon tape that between two handrail tubes, tack down, the backrest face 11 of formation chair with backrest seat 18 on the left and right arm-rest frame with pivot pin 19.Extension spring 20 is housed in the backing tube, and the upper end of spring is connected with backing tube with pin 21, is the movable end of spring; The lower end of spring hangs on the backrest seat pivot pin, stiff end for spring, when spring power pulls down backing tube, the backing tube slotted eye should slide freely on pivot pin, the lower surface of pipe is abutted on the bottom surface or the back side of backrest seat tightly, backing tube firmly is positioned upright or level, should be nimbly and freely when pulling the upset backing tube.Balustrade panel 10 usefulness sunk head rivets are fixed on the arm-rest frame.The geometry yardstick of chair is got the human body average dimension, and the length of each position of articulating point size of chair " fork is cut---frid swing mechanism ", frid chute should be determined under the prerequisite of obeying the chair overall dimension.The motion of mechanism track should be able to satisfy the functional requirement that chair launches and folds, and launches the back bar frame and should lock, and side direction firmly can not be pulled; Each overlapping of folding back should be drawn close.Each component movement process does not allow interference.
