Structure of the present utility model as shown in the figure.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the A-A profile of jig 5 in the utility model.

As shown in Figure 1, the utility model adopts forward and backward support 11,2 supporters as terraced chair, the both sides of fore-stock 11 be "

" shape, its underpart connects with bracing piece; The both sides of after-poppet 2 are straight-bar, connect with bracing piece between them. The end of lateral part, fore-stock 11 both sides and the upper end of after-poppet 2 both sides and the back edge of top plate 6 are passed flexible connection with axle 4, front and back support 11,2 and top plate 6 can rotate around axle 4. The middle and upper part of after-poppet 2 both sides and the back edge of la m 8 are passed flexible connection with axle 3, and la m 8 can be around axle 3 upsets. The corner of both sides, fore-stock 11 top respectively is provided with a telescopic jig 5, the structure of jig 5 as shown in Figure 2, it is by 21 groups on axle 17, stage clip 18, sleeve 19, pad 20 and screw Become. One end of axle 17 has a boss, in the other end of axle 17 screwed hole is arranged, and this end passes the respective aperture on the fore-stock 11, its overcoat one stage clip 18, and stage clip 18 overcoats one sleeve 19, screw 21 pass in the screw of pad 20 and sleeve 19 precession shafts 17. Still by shown in Figure 1. Before being on the position of same level line with axle 3 of support 11 both sides respectively be provided with a jig 7, the structure of jig 7 is identical with jig 5. When upper, when la m is dug horizontal level, only need the

jig

5,7 of fore-stock 11 both sides is advanced respectively inwards,

jig

5,7 just can block upper, la m 6,8.

Jig

5,7 also available latch is replaced, namely have pin hole in the corner of 11 liang of upper lateral parts of fore-stock and with position that axle 3 is in same level, upward, respectively be fixed with latch on la m 6,8 two bottom sides and the corresponding position of fore-stock 11 both sides pin holes, when upper, when la m 6,8 is horizontal, only need latch is inserted pin hole on the fore-stock 11, just can fix, la m 6,8. One end of connection strap 16 and the middle part of after-poppet 2 are flexibly connected with axle 1, and the other end of connection strap 16 is connected with axle 12 with the rear portion of lower plywood 9, between connection strap 16 and after-poppet 2 and the lower plywood 9 relative motion can take place respectively. Flexible connection is passed with axle 10 in the both sides at the middle part of lower plywood 9 and fore-stock 11 middle parts, and lower plywood can overturn within the specific limits around axle 10; At the rear part edge two ends of lower plywood 9 boss 14 is arranged respectively, a telescopic pin 13 is arranged in the boss 14, each fixes " U " shape clamp 15 both sides, lower plywood rear portion.

When using Collapsible ladder chair, as long as till forward and backward support 11,2 is flared to lower plywood 9 and is horizontal, connection strap 16 just falls into clamp 15 like this, again pin 13 is extracted, and block connection strap 16 from the top, just can be so that between lower plywood 9 and the connection strap 16 relative motion can not take place. Namely by forward and backward support 11. 2 connection straps 16 are in stable state with the mechanism that lower plywood 9 forms.

When terraced chair uses as adult's chair, upward, la m 6,8 falls naturally, become the backrest of chair, at this moment the rear portion of top plate 6 is blocked by the bracing piece of after-poppet 2, la m 8 is blocked by the boss on the lower plywood 9 14, and they can not be around doing clockwise rotation with the connecting axle of after-poppet 2 separately.

When terraced chair uses as the high chair of child, as long as la m 8 is started, advance the left and right sides of blocking la m 8 respectively to get final product inwards the jig on the fore-stock 7, the child is sitting on the la m 8 like this, pin is placed on the lower plywood 9, just can be sitting in adult's table limit safely and have meal or play.
