Abstract
An auxiliary apparatus with a movable seat includes at least one upper tube, a seat, at least one combining plate for combining the seat and the upper tube, and two positioning devices installed in first and second ends of the upper tube respectively. The seat is adapted for the handicapped with disabled lower limbs or those with difficulty in walking to sit on and is movable between the first and second ends of the upper tube. The combining plate includes two positioning grooves. The two positioning devices can be releasably engaged with the two positioning grooves of the combining plate to fix the seat on the first end or the second end of the upper tube. The two positioning devices are structurally simple and allow a position of the seat to be changed more conveniently.

An auxiliary apparatus with a movable seat comprising:
- a supporting frame including spaced first and second upper tubes, with the first upper tube extending in an axial direction and including first and second ends spaced in the axial direction, with a positioning hole formed in each of the first and second ends of the first upper tube;
- a seat including a lower surface supported on the first and second upper tubes of the supporting frame, with the seat being movable between the first and second ends of the first upper tube;
- a combining plate connecting the first upper tube with the lower surface of the seat and including two fixing grooves spaced in the axial direction;
- and
- first and second positioning devices mounted in the first and second ends of the first upper tube respectively, with each of the first and second positioning devices including a positioning member and an elastic piece, with each positioning member having a stopping portion, with the stopping portion of the positioning member of the first positioning device engaged with the positioning hole of the first end of the first upper tube, with the stopping portion of the positioning member of the second positioning device engaged with the positioning hole of the second end of the first upper tube, with each elastic piece including a first section pressed against the first upper tube and a second section coupled with one of the positioning members;
- wherein when the seat is moved to the first end or the second end of the first upper tube, one of the two fixing grooves of the combining plate can be aligned with the positioning hole in the first end or the second end of the first upper tube and engaged with the stopping portion of the positioning member of the first or second positioning device so that the seat is fixed;
- wherein when the positioning member of the first or second positioning device is pressed, the stopping portion of the positioning member can be detached from an associated fixing groove, so that a position of the seat can be changed.
