The specific embodiment

Please be simultaneously referring to Fig. 1 and Fig. 2, the simple and easy folding structure of this medichair includes pedestal 10, back rest 20, leans on foot group 30, seat frame 40, one symmetrical trace 50 and a fixture 60.This back rest 20 is hubbed at an end of pedestal 10.One is located on the pedestal 10 away from the other end of back rest 20 by foot group 30.One seat frame 40 and a trace 50 be located at respectively back rest 20 with by on the foot group 30, this seat frame 40 and trace 50 make the back rest 20 interlock swing of leaning on foot group 30 synchronously.Fixture 60 is hubbed between two handrails of pedestal 10, fixedly the position behind the pivot of the back rest 20 pendulum location.

Two lateral margins of this pedestal 10 are respectively equipped with handrail 11, and four corners of pedestal 10 are provided with roller 12, the comfortable storing of hands that this handrail 11 is available for users to.

This back rest 20 is hubbed at 11 on two handrails, and this back rest 20 can produce relative pivot pendulum relation with pedestal 10, and this back rest 20 includes first end 21 and second end 22, lies and lean in the back that its first end 21 is available for users to.

Should be formed by mutually assembling by a plurality of connecting rods by foot group 30, include first end 31 and symmetric second end 32 of  shape, the foot that its first end 31 is available for users to puts, its second end 32 is located at two sides away from the pedestal 10 of back rest 20 other ends, and be provided with a symmetric fulcrum 33 between

first end

31 and 32 at second end, and between the fulcrum 33 and second end, be provided with a symmetric pivot part 34.

This seat frame 40 has symmetric first end and second end, and its first end is hubbed at fulcrum 33, and its second end is hubbed between back rest 20 first ends and second end, is available for users to take between this first end and second end.

This symmetrical trace 50 has first end and second end, and its first end is hubbed at pivot part 34, and its second end is hubbed at second end of back rest 20.

Fixture 60 1 ends are located in the perforation 13 of pedestal 10, and its other end is located in the perforation 23 of back rest 20, and this fixture 60 optionally fixes the position behind the back rest 20 swing location, sees also Fig. 3.

See also Fig. 4, wherein this fixture 60 includes the slide 61 of a tool hook groove 611 and is slidedly arranged on the slide block group 62 in the chute 612 and fixes the handle 63 of slide block group 62, it is located at 11 on two handrails and adjoining back rest 20 rear sides this slide 61, and this handle 63 is to be located at adjoining and on the pedestal 10 of the chute 612 of slide 61, and this slide block group 62 comprises sleeve 621, packing ring 622, slide plate 623 and bolt 624, after this sleeve 621 wears the perforation 13 and the chute 612 of pedestal 10 earlier and is slidedly arranged on slide plate 623 on the hook groove 611, be locked in sleeve 621 by bolt 624 again, and be provided with packing ring 622 between slide plate 623 and

slide

61 and 621 in sleeve, by this, when handle 63 is upwards pulled and an end face 631 of this handle 63 will be away from sleeve 621 time, see also Fig. 5, Fig. 6, back rest 20 can at random be swung and the related slide block group 62 that involves is slided in chute 612 simultaneously, behind back rest 20 swing location, handle 63 can be pulled downwards and be impelled handle 63 end faces 631 to fix the side of sleeve 621, make slide block group 62 strong fixs and impel back rest 20 not move, see also Fig. 7, Fig. 8.

See also Fig. 9, when the user desire is adjusted back rest 20 and is leaned on the reclining angle of foot group 30, the pulling handle 63 that can make progress makes handle 63 end faces 631 adjust afterwards away from sleeve 621, referring to Fig. 6, when user can be slightly to layback and when utilizing the gravity of health to adjust back rest 30 to suitable layback angle, referring to Figure 10, Figure 11, this trace 50 is the pivot part 34 that holds by foot group 30, and this seat frame 40 is also received and is held fulcrum 33 simultaneously, in order to do make by foot group 30 first ends 31 can be driven by seat frame 40 and trace 50 and along with back rest 30 to layback and synchronously swing, see also Figure 12, otherwise, when back rest 30 turns forward, this trace 50 is received the pivot part of holding by foot group 30 34, and this seat frame 40 also holds fulcrum 33 simultaneously, can be driven by seat frame 40 and trace 50 and along with back rest 30 turns forward and synchronously swing in order to do making by foot group 30 first ends 31.

Can summarize from the above description and the utlity model has following advantage:

1, the seat frame of the simple and easy folding structure of medichair of the present utility model and trace are hubbed at back rest and lean on the foot group, so can be driven by seat frame and trace and put with the synchronous pivot of back rest by the foot group, and can adjust back rest simultaneously and lean on the foot group, so have saved back rest and the time of leaning on the foot group adjusted respectively according to the demand of user to best position.

The above only is preferred embodiment of the present utility model; can not limit this utility model practical range with this, therefore, the change of all numerical value or the displacement of equivalent elements; or, all should belong to protection domain of the present utility model according to equalization variation and modification that this utility model claim is done.
