The specific embodiment

As shown in Figure 1, 2, this utility model is to comprise pedal 1, elastic parts 2 and fixture 3, and is arranged on the treadle 41 of wheelchair 4, and wherein treadle 41 is the direct vertical extensions of wheelchair 4 skeletons that continue, and it is characterized in that:

Extending forward in addition on the treadle 41 and be provided with a bit of pole 411, is to offer the caulking groove 412 that connects at least together to rod end on the bar periphery of pole 411;

Be to extend to be provided with at least one articulated section 11 of establishing tool pivoted hole 111 and to wear pivot for pole 411 relatively on the pedal 1, in this example, this articulated section 11 is to be made as tank empty in, and pivoted hole 111 then is the some of tank, for articulating pole 411; Again, be to be provided with positioning piece 12 on the pedal 1 with respect to articulated section 11, this keeper 12 is that the act bolt is an example in this example;

Two ends the 21, the 22nd of elastic parts 2 are arranged at respectively on keeper 12 and the pole 411, and in this example, this elastic parts 2 is preferably a torque spring;

Fixture 3 is bar footpaths of relative pole 411 and be shaped to soft sleeve empty in, and the rod end of pole 411 is sheathed relatively, in order to do pedal 1 is positioned on the pole 411, and is reached spacing purpose.

Mat it, when group is established, as Fig. 2, shown in 3, be to make elastic parts 2 be placed in the articulated section 11 in advance, pivoted hole 111 with pole 411 relative pedals 1 articulated section 11 stretches through again, the one end 21 suitable caulking grooves 412 that communicated by pole 411 peripheries of this elastic parts 2 stretch through, and be embedded in the caulking groove 412, make the other end 22 direct hooks of elastic parts 2 be located on the keeper 12 on the articulated section 11 again, at last, make fixture 3 relative poles 411 ends wear in the pivoted hole 111 that is positioned pedal 1 articulated section 11 again, in order to do make it can't be along pole 411 and slippage with restriction pedal 1.

Under normality, this pedal 1 is to be subjected to the elastic force of elastic parts 2 and vertical treadle 41 sides that are placed on, and makes wheelchair 4 front ends not have an obstacle, is beneficial to the occupant and stands or leave wheelchair.

When using, as shown in Figure 4, be to make the occupant directly step on be located on the pedal 1 with its foot, but the elastic parts 2 one ends 22 in the interlock pedal 1 are mounted in the other end 21 turns in pole 411 caulking grooves 412 relatively, make pedal 1 change into horizontally disposed state by the state of original vertical vertically-arranged, and under the state of pedal 1 horizontal horizontal, this elastic parts 2 will be compressed, when in case pedal 1 leaves in occupant's foot, this pedal 1 will automatically return to initial vertical vertically-arranged state by the elasticity of elastic parts 2, in order to do to reach the effect that folds automatically.

In addition, this utility model also has other preferable example, as shown in Figure 5, be to make the articulated section 11A of pedal 1 be directly formed to two relative lugs, and on lug, establish tool pivoted hole 111A, and this keeper 12A can be one by the pedal 1 integrated body of rod, and be provided with a locating hole 121A in the body of rod, one end 22 for elastic parts 2 is embedded the location wherein, the fixture 3A that is arranged at pole 411 ends then can adopt an alignment pin radially to be extended through on the pole 411, makes pedal 1 be subjected to only supporting and locating of alignment pin.

As shown in Figure 6, be to make the keeper 12B on the pedal 1 on the articulated section 11 of pedal 1, be directly formed to a buckle ear, and make retention means 3B be made as a clasp and directly buckle and be located on the pole 411 again; When group is established, be to make that elastic parts 2 one ends 21 are to be embedded in the caulking groove 412 of

pole

411,22 buttons in the other end are located on the keeper 12B, and pedal 1 then ends by supporting of clasp, and is positioned all the time on the pole 411.

Be with, pedal of the present utility model is to collapse in the treadle side automatically when not using, be beneficial to the occupant and stand,, then can transfer the state of horizontal horizontal automatically to as when trampling use, in operation, other people need be dependent on fully, the occupant can be seen through from line operate, quite convenient in the use.
