In the present embodiment, the seat also includes two enclosing covers 4 of left and right, and two enclosing cover 4 is placed on left and right two and leaned against respectively
The outside of rotating seat 11, so that the revolving part 61 be covered.
It is described to lean against 1 and be set to inverted-loop tube as shown in figure 1, in the present embodiment, including left and right two lean against pipe 12 and
The first transverse pipe 13 that the left and right two leans against the upper end of pipe 12 is connected to, the left and right two leans against rotating seat 11 and is respectively arranged at institute
State left and right two and lean against the lower end of pipe 12, the left and right two is also associated with the second transverse pipe 14, the driving between leaning against the upside of pipe 12
Mechanism 64 is connected in second transverse pipe 14.In other embodiments, it is described to lean against 1 it can also be provided that tabular, described
Drive mechanism 64 is arranged at tabular and leans against 1 rear side.
In the present embodiment, the portions 2 are set to tabular, and two portions rotating seats 21 of the left and right are respectively from the tabular
The left and right sides rear end of portions 2 is up extended.In other embodiments, the portions 2 are it can also be provided that the seatpost of left and right two,
Then cloth of choosing a place to give a banquet is covered in seatpost, in this way, the portions rotating seat 21 is arranged at the seatpost rear end.
The handrail 3 takes the shape of the letter U, including left and right sides handrail 32 and is connected to before the front end of left and right sides handrail 32
Handrail 33, two handrail rotating seats 31 of the left and right are integrally formed at the rear end of left and right sides handrail 32 respectively.
In the present embodiment, preferably, being convenient in demoulding in order that obtaining portions rotating seat 21, the portions rotating seat 21 includes
The teeth groove portion 216 of second teeth groove 215 is set and the occlusion part 217 of the side of teeth groove portion 216 is fixedly connected on, it is described to block
Portion 217 is arranged at the side of handrail rotating seat 31.
During the operating principle of the present invention：
Under original state, because the effect of the first spring 53, one end of the latch 51 can be located at the depth of arc solution locked groove 111
In the consistent first paragraph groove 112 of degree, the other end of latch 51 is then fully located at the first sector hole of portions rotating seat perforation 211
In 212, and stop pin 52 is in the presence of second spring 54, and one end is located in lock hole 311, and the other end is located at perforation 211
In second sector hole 213；Operation drive mechanism 64 pulls steel wire up to move, so that revolving part 61 rotates, revolving part 61 revolves
When turning, one is that can compress the 5th spring 62 by 7 font spring bases 613, in addition, the inclined-plane 6120 of revolving part 61 can be with pushing away
The inclined-plane 631 of moving part 63 produces dislocation, so as to drive impeller 63 to be moved toward the direction of gear 41, so that by gear 41 toward remote
Lean against the direction movement of rotating seat 11 so that the disengaging of gear 41 is engaged with the first teeth groove 114, is only engaged with the second teeth groove 215,
Now, leaning against 1 rotation can rotate relative to portions rotating seat 21, this when, can rotate forward or backward and lean against 1.If backward
Rotation leans against 1, and one end of latch 51 can be moved in first paragraph groove 112 always, so as to not interfere with stop pin 52, be passed through
That thicker tooth 411 of the thickness of gear 41 that several teeth groove deep with the first teeth groove 114, the depth of the second teeth groove 215 are matched somebody with somebody
Close, may be such that leaning against 1 relative portions 2 is in different angles of inclination, i.e. adjustment leans against 1 angle；Rotation leans against 1 forward, if lock
Rationed marketing 52 still leans against 1 angle adjustment state also in first paragraph groove 112, then, and certain angle is rotated to forward when leaning against 1
When, the second segment groove 113 of one end of latch 51 then with arc solution locked groove 111 coordinates, now, and latch 51 can then be promoted past
The direction movement of stop pin 52, so as to promote stop pin 52 to be moved toward the direction of handrail rotating seat 31, unblock is rotated to when leaning against 2
When the end of pin 51 and second segment groove 113 coordinates, stop pin 52, which is pushed into, to be completely disengaged from perforation 211 and is fully located at handrail rotation
In the lock hole 311 of swivel base 31, so that the handrail rotating seat 31 can rotate relative to portions rotating seat 21；Now, continue forward
Rotation leans against 1, after leaning against 1 and encountering handrail 3, leans against 1 continuation and rotates forward, can press down handrail 3, until the portions
2nd, handrail 3, lean against 1 and be mutually close together, now, seat folds fold completely, as shown in Figure 10.I other words, receiving
When closing seat, without pulling down handrail 3, handrail 3 can fold foldings with 1 linkage is leaned against, in this way, fold operate it is also very convenient, and
The seat volume of timber after folding is small, seldom takes up space.
Preferably, when seat be in collapse state when, the thicker tooth 411 of the thickness of gear 41 simultaneously with the first teeth groove 114 with
And the deeper teeth groove engagement of the one of depth of the second teeth groove 215, so that seat lock is scheduled into collapse state.When seat to be deployed
When, the drive mechanism 64 is operated, then release the lock locking mechanism rotates and lean against 1 backward.Because handrail rotating seat 31 revolves with portions
Handrail resetting means is provided between swivel base 21, during the rotation of handrail 3 is folded, the spacer pin 71 is in stroke groove 314
It is mobile, so as to compress the 3rd spring 72；During deploying seat, when leaning against 1 and no longer depress handrail 3, in the 3rd spring 72
Under restoring force effect, the handrail 3 automatically resets.
As shown in Fig. 1,10, described lean against is also associated with ceiling bar 5 on 1, the left and right sides lower end difference of the ceiling bar 5
1 left and right sides is leaned against described in being articulated in angle adjustment.The ceiling bar 5 is known manner, top with the articulated manner for leaning against 1
Fluffy bar 5 relative can be adjusted to different angles.When seat is folded, the ceiling bar 5 can rotate with leaning against 1, if folded
Preceding angled, after seat is folded, can directly pull ceiling bar 5 makes it be stacked on handrail 3.
The front end of portions 2 is also associated with U-shaped shank backrest 6, and the left and right sides rear end of the U-shaped shank backrest 6 respectively can phase
The front end left and right sides of portions 2 is connected to angle adjustment.After seat is folded, shank can be rotated according to the height for leaning against 1
The position parallel with portions 2 is reached by 6 or rotates it to the state for being laminated on the lower section of portions 2.Specifically, if leaned against
1 is higher, so that after its folding, horizontal direction length can be long, now rotation shank backrest 6 reaches parallel with portions 2
Position, shank backrest 6 and leans against 1 entire length and is no longer than and leans against 1, and the volume of timber is folded so as to will not increase；If shank backrest 6 with
The entire length for leaning against 1 is longer than and leans against 1, then can rotate shank backrest 6 makes it be laminated on the lower section of portions 2.
It is a left side with the place of two side handrail 33 where shank backrest 6 before being where leaning against 1 after being in above-mentioned upper description
The right side, is upper to lean against the place of the first transverse pipe 13, under being where portions 2.
