Embodiment

Refer to shown in Fig. 1-Fig. 8, the adjustment structure of the foot-operated rotating function of the utility model chair, it, which is constituted, includes one Chair 10 and the sliding unit 50 and pedal unit 60 being connected on the chair 10, wherein：

The chair 10 is typically to use chair at home, by seat support 11, the chair back 12 and 13 groups of the chair frame positioned at the side of seat support 11 2 Into with an accommodation space 14 between two chair frame 13, to set the mobile unit 20.

The sliding unit 50 is made up of, the framework below the chair a framework 51, adjustable shelf 52, two groups of slide rails 53 51 be in square frame structure, and upper limb locks with the bottom of seat support 11, and two sides are fixed with corresponding chair frame 13.And the adjustable shelf 52 In the framework 51, its bottom is provided with some pulleys 55, makes the adjustable shelf 52 can slide displacement.Furthermore two groups of slide rails 53 are set Between the framework 51 two side faces relative with adjustable shelf 52, the adjustable shelf 52 is made to be passed in and out with slide construction in the framework 51 Outside, and using locator 54 its position is limited, is disclosed technology because of the locator 54, repeats no more.

The pedal unit 60 is arranged on the adjustable shelf 52, and its composition includes a body 61, and a positioning seat 62, this Body 61 is that a body bends an angle, and an outer end sets an articulated section 63, and the ora terminalis of the other end is available for a rotation section 64 to set fixation. The articulated section 63 is square-shaped, and an outside is provided with a pivot hole 631 and some positioning holes 632, some positioning holes 632 and with this Pivot hole 631 is that the arrangement of arc round shape is made in the center of circle.

The side group of rotation section 64 2 is connected to drive link 641, and the outer end each group of two drive link 641 connects 642 groups of a pedal and connect, can The trample action of rotate formula is placed on two pedal 642 for user's both feet.And the outer rim spiral shell of rotation section 64 is provided with an adjustment Button 643, to adjust the elasticity when rotation section 64 is rotated, is background technology because of this, repeats no more.

The positioning seat 62 is fixedly arranged on the adjustable shelf 52, is the pedestal without exception in ㄩ fonts, and its inner rim has a holding part 621, just it is available for the articulated section 63 to set, and fixed using the pivot group of a pivot 65；If the lateral surface of positioning seat 62 1 is to should again The appropriate place of dry positioning hole 632 is formed with a through hole 622, and is combined in the fixed nut 623 of the outer rim of through hole 622 to spiral shell group One limiter 66.

The one end of limiter 66 in the through hole 622, its to should some one end inner edges of positioning hole 632 provided with a positioning Bar 661, the other end is provided with a button 662, and the inner of locating rod 661 is arranged a spring 663, when the button 662 is pressed, can made The locating rod 661 make elastic telescopic and it is outwardly in any inner edge of positioning hole 632 or inwardly retract.

The utility model is in use, as shown in figures 3 to 6, the pedal unit 60 is pulled out from the lower section of chair 10, then incites somebody to action The angle adjustment of its body 61 just can put both feet the formula trample action that rotated on two pedal 642 to use state, and this When body 61 makees angle adjustment, it is only necessary to operate the limiter 66, make the limiter 66 locating rod 661 depart from positioning hole 632 just can, After the completion of adjustment, then the sleeve of locating rod 661 for making the limiter 66 not only constitutes component in corresponding positioning hole 632 It is more exquisite simple, and manufacture and assembly cost can be reduced, while the adjustment operation of angle is more convenient, use the change of angle Selection is more, and can be applicable the use of more different heights.When using finishing, as shown in Figure 7, Figure 8, by the angle of the body 61 Degree adjust to collecting state, just pedal unit 60 can be promoted in the accommodation space 14, using or collection be all not take up space, it is non- The environment for being often adapted to general life at home is used.

In summary, the utility model has its splendid progress practicality in fact in like product, while domestic and international all over looking into Also identical construction is found no in technical data, document on this class formation to exist formerly, is real with the utility model Possesses new patent important document, whence is filed an application in accordance with the law.
