The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is a kind of improvement structure of the plate of lying on the back, it mainly by seat 1, frame 2, fork 3, upward by pin 4, form by pin 5, drag rope of elasticity 6, grip stay cord 7 down.

Described frame 2 is made up of longeron 21, vertical support frame 22, preceding underframe 23, back underframe 24, handrail tube 25.The front end of described longeron 21 is vertically fixed on the middle part of vertical support frame 22, the rear end of longeron 21 is vertically fixed on the middle part of back underframe 24, the upper end of vertical support frame 22 is fixed on the middle part by pin 4, the middle part of underframe 23 before the lower end of vertical support frame 22 is fixed on, longeron 21 and vertical support frame 22 constitute a triangular support.Described handrail tube 25 laterally is set in the middle part of longeron 21.

Described seat 1 is made of seat board 11, backrest 12 and support 13.Frame 2 longerons 21 middle parts that described seat board 11 is fixed, backrest 12 lower ends are fixed in an end of longeron 21 middle parts and close seat board 11, the back of backrest 12 connects by the upper end of latch 9 (as shown in Figure 3) support 13, and the lower end of support 13 is hinged on the longeron 21 and can swings around this pin joint.When latch 9 was transferred to, backrest 12 also can be fitted in (as shown in Figure 8) on the longeron 21.

Described grip stay cord 7 has two, the two ends of underframe 23 before their lower end is separately fixed at, and its place of shaking hands 71 can be enclosed within the two ends of handrail tube 25 respectively or take off from the two ends of handrail tube 25.

The upper end of described fork 3 is hinged on the upper end of vertical support frame 22, is fixed on the lower end of fork 3 down by pin 5 middle parts.

With reference to shown in Figure 3, described fork 3 is provided with a plurality of grooves 31 as Fig. 2, and hook 61 is housed on the outer end of drag rope of elasticity 6, and this hook 61 can be articulated in a groove 31 in a plurality of grooves 31 on the fork 3.In the present embodiment, the mounting means of drag rope of elasticity 6 is: the inner of drag rope of elasticity 6 is fixed on the bottom of vertical support frame 22, and the middle part of drag rope of elasticity 6 is walked around pulley 81, the pulley 82 of vertical support frame 22 bottoms, pulley 83 backs of fork 3 lower ends, its outer end of being installed in vertical support frame 22 tops and is articulated in the central slot 31 of fork 3 by linking up with 61.

As shown in Figure 3, be provided with the pin-and-hole 221 on vertical support frame 22 tops of the top of running through fork 3 and frame 2 at the place of being abutted against, vertical support frame 22 top of the top of fork 3 and frame 2, the latch 8 of in this pin-and-hole 221, can pegging graft.Be provided with the putting hole 222 of latch 8 at the top of vertical support frame 22, latch 8 can be placed in this putting hole 222.
