Abstract

The utility model relates to a folded chair. The utility model is characterized in that the folded chair is composed of a chair backrest, a seat pad, a guard sheet for the seat pad, a front body supporting rack and a back foot rack, wherein the back of the seat pad is connected with the front body supporting rack. An n-shaped sheet is clamped at the bottom edge of the seat pad, and the guard sheet is fixed by screws to the bottom surface of the seat pad, so that a push rod of the back foot rack passes through the guard sheet and can move in the guard sheet. The back foot rack passes through the guard sheet on the bottom surface of the seat pad, and the face of the chair backrest has different heights. When a plurality of folding chairs are folded together, the front body supporting rack can be arranged into the different heights of the face of the chair backrest, the and the chairs can be prevented from being damaged due to collision when the chairs contact each other.

Description

Fold-down seat

The utility model relates to a kind of fold-down seat, refers to that especially a kind of rear leg push rod is supported on the fold-down seat on the catch of seat cushion bottom surface.

Though the fold-down seat that current people use brings convenience, also have problems, promptly the hinge in order to articulate between seat cushion and rear support stand owing to stressed fragile greatly, causes whole chair to be scrapped; When the collection of most fold-down seat desires folded mutually or mutually by the time owing to rely on mutually between each bar, phase mutual friction and damaging easily.

The purpose of this utility model is that a kind of fold-down seat will be provided, and it not only protects seat cushion, and helps the arrangement of most chairs and collect superimposed.

The purpose of this utility model is achieved in that fold-down seat is made up of the chair back, seat cushion, predecessor's support and rear leg, chair back front is to forming a gradient shape between outer most edge, its outer rim place is a circular arc to rear side again, and respectively there are a tank and predecessor's support snapping in both sides, the back side, and push rod is contained in the circular arc of chair back back side outer rim, spiral shell is solid again; Establishes a rigidity  shape sheet at the root edge of seat cushion rear and predecessor support joint folder, the seat cushion bottom surface catch that is spirally connected, rear leg push rod place and activity therebetween; Two clasps can connect arranges a plurality of fold-down seats.

Because adopt such scheme, rigidity  shape sheet of the present utility model is the riveting point of pivot joint, and has protected seat cushion; Rear leg is set on the catch of seat cushion bottom surface, can fold and strut for convenient receipts of fold-down seat; Amount to the cambered surface in chair back front and the gradient of formation, cause drop space with height, with provide most fold-down seats folded mutually in regular turn, arrange the location, predecessor's support of having avoided each fold-down seat collides mutually and causes damage; Fold-down seat can utilize two clasps to make each fold-down seat marshalling.

Below by accompanying drawing and embodiment the utility model is further described.

Among the figure: 10 fold-down seats, 11 chair back, 12 seat cushions, 13 predecessor's supports, 14 rear legs, 20 screws, 21  shape sheets, 30 catch, 100 pairs of clasp 110 tanks, 130 cross bars, 140 shape supports.

Referring to Fig. 3; The utility model embodiment consists predominantly of a chair back 11, seat cushion 12, predecessor's support 13, rear leg 14, the chair back 11 is backrest bodies, and its front is the plane of arc slightly, and outer most edge forms a gradient, be a circular arc to rear side again, respectively there is a tank both sides, the back side; Seat cushion 12 is that plastic material is one-body molded; Predecessor's support 13 is the rod member of  shape, and its two side stand has certain-length, and is provided with a cross bar 130; Rear leg 14 is rod members that certain width is arranged, and its front end both sides slightly bend inwards, and the bottom connects solid with a shape support 140, form holistic polygon.

As shown in Figure 4; The tank 110 at the chair back 11 back sides in the fold-down seat 10 just and the rod member snapping of predecessor's support 13 tops, and is contained in the circular arc of the chair back 11 back side outer rims predecessor's support 13 push rods, uses screw fastening again.

Shown in Fig. 5,6; Seat cushion 12 rears and predecessor's support 13 joints are to adopt the riveted joint mode that both are articulated; Because seat cushion 12 is a plasthetics, directly rivet clasp easily breaks, thereby adopts a rigidity  shape sheet 21 folders to pull and can finish pivot joint at the root edge of seat cushion 12; A catch 30 is established in seat cushion 12 bottom surfaces in addition, and directly spiral shell is solid in the bottom surface of seat cushion 12, and forms long activity space, place therebetween to allow rear leg 14 push rods, and rear leg 14 articulates with predecessor's support 13, promptly forms a fold-down seat 10.

As shown in Figure 7; When desiring to fold fold-down seat 10, only need mention the front end of seat cushion 12, be set in the landing from top to bottom of taking advantage of a situation in catch 30 formed spaces of rear leg 14 in the seat cushion 12 bottom surface catch 30 and promptly finish folding to the bottom of catch 30; If desire to strut,, seat cushion 12 set level get final product promptly with the opposite direction application of force.As shown in Figure 8; When more fold-down seat 10 desires to fold collection, can be folded mutually one by one in regular turn, making the chair back 11 positive outer most edge of each fold-down seat 10 form a gradient is a circular-arc part to rear side again and leans on mutually, the space of the chair back 11 two sides height fall in the gradient that forms just can hold the protrusion arc bar on top, the chair back 11 back side, make most fold-down seats 10 phase poststack up and down, 11 of the chair back contact with each other, because the chair back 11 is that the foamed plastic body is not easy to wear.

As shown in Figure 9; 10 of fold-down seats can be arranged and be connected into some quantity mutually, and are the arrangement shape; The practice be at each fold-down seat 10 joint card with two clasps 100, promptly be stuck on predecessor's support 13, can avoid each fold-down seat 10 knock against each other and impaired when arranging, can not produce too big noise yet.
