The specific embodiment

Referring to Fig. 1, Fig. 2, this turns stool and comprises: handle 1, three-legged support 2 and seat cloth 3; Described handle 1 is provided with crossbeam 1-1 for inverted trapezoidal structure and at trapezoid middle part; Described A-frame 2 comprises hollow bearing 2-0, central slide bar 2-1 and supporting leg 2-3, and wherein, two handle 1 symmetries are hinged on the top of hollow bearing 2-0, and two crossbeam 1-1 are parallel all the time; Two crossbeam 1-1 and central slide bar 2-1 top are respectively arranged with a upper connecting rod 2-2, upper connecting rod 2-2 two ends respectively with crossbeam 1-1 and central slide bar 2-1 upper articulation; The slide bar 2-1 of central authorities slides in the hole of hollow bearing 2-0; The end of three supporting leg 2-3 is divided equally the bottom that is hinged on hollow bearing 2-0; Two of sitting cloth 3 is connected with the handle of two handles 1 respectively.Be respectively arranged with sliding support 2-4 on three supporting leg 2-3 outer surfaces, be provided with hold-down support 2-5 in central slide bar 2-1 lower end, the two ends of three lower link 2-6 are hinged with sliding support 2-4, hold-down support 2-5 respectively.

When using as crutch, hold the handle of handle 1, by the supporting leg 2-3 support ground of three-legged support 2, owing to abandoned accordion structure of the prior art, crutch can bear very big power, and can not rotate.When using as stool, two handles 1 are outwards strutted, the crossbeam 1-1 of handle 1 drives upper connecting rod 2-2, and then drives central slide bar 2-1 and move upward, and three supporting leg 2-3 are also opened thereupon, sits cloth 3 and is stretched tight flatly, takes a load off one's feet for the people.

Referring to Fig. 3,5, be respectively arranged with a grab 2-7 in the inboard of three supporting leg 2-3; Be provided with cutting ferrule 2-8 in the corresponding position of central slide bar 2-1, cutting ferrule slides along the axial short distance of central slide bar 2-1, and resets by spring 2-9.This design is to turn stool when the folding in order to make, and as the crutch time spent, three supporting leg 2-3 are effectively locked unlikely opening, as long as grab 2-7 is stuck in the cutting ferrule 2-8; Cutting ferrule 2-8 top is cylindrical body of rod 2-15, cylindrical body of rod 2-15 places in the central slide bar 2-1, spring 2-9 is socketed in outside the cylindrical body of rod 2-15, the lower surface on the top of cylindrical body of rod 2-15 is as the upper support face of spring 2-9, simultaneously in central slide bar 2-1 interior plug is set, the upper surface of interior plug is as the lower support face of spring 2-9; Spur cutting ferrule 2-8 downwards, grab 2-7 deviates from cutting ferrule 2-8, looses one's grip, and cutting ferrule 2-8 is return (when grab 2-7 was stuck, the elastic force of spring 2-9 can prevent that also grab 2-7 and cutting ferrule 2-8 break away from) under spring 2-9 effect; For the ease of pulling cutting ferrule 2-8, be provided with draw ring 2-14 in cutting ferrule 2-8 lower end.

Referring to Fig. 4, described three supporting leg 2-3 are provided with expansion link 2-10 in a supporting leg 2-3 therein, are provided with locking system 2-13 between supporting leg 2-3 and the expansion link 2-10.This design is for the ease of adjusting the length of the supporting leg 2-3 when using as crutch.

All be provided with two spacer pin 2-11 at every supporting leg 2-3 middle part, sliding support 2-4 is stuck on two supporting leg 2-3 bodies of rod between the spacer pin 2-11, and short distance slides; The position that the spacer pin 2-11 of downside is provided with, after making that supporting leg 2-3 is strutted fully, the angle of supporting leg 2-3 and lower link 2-6 is about 90 °, this design, be to turn stool when using as stool in order to make, three triangle area maximums that supporting leg 2-3 lower end touchdown point is enclosed, the stability of assurance stool; The position that the spacer pin 2-11 of upside is provided with, after making supporting leg 2-3 by complete folding, sliding support 2-4 upwards is in contact with it, and the position that central slide bar upwards slides is defined, this design has fully guaranteed to turn stool when using as crutch, the stability after two handles 1 close up.

On the seat cloth 3 of handle 1 junction, be provided with the semicircular hole 4 of holding, be convenient to staff and grip.

Described central slide bar 2-1 on the central slide bar 2-1 body of rod below the hollow bearing 2-0 lower surface, is provided with central slide bar spacer pin 2-12, and this is in order to guarantee that sitting cloth 3 is stretched tight flat.When central slide bar spacer pin 2-12 contacted with hollow bearing 2-0 lower surface, two upper connecting rod 2-2 were in the level position.
