Abstract

A stepper comprising: a direction controller having a front wheel set and a steering wheel connected to the front wheel set; a rear wheel transmission having a gear transmission and a rear wheel shaft, the gear transmission having an active gear, a chain and a passive gear, the active gear connected to the passive gear via the chain, the rear wheel shaft having a rear wheel set and connected to the passive gear; a supporting shaft connected to the direction controller and the rear wheel transmission; and a foot-hand swinging set having a pedal and a joystick having a handle, the pedal mounted on two sides of the supporting shaft, one end of the pedal connected to the active gear, the joystick connected to another end of the pedal. The present invention can be propelled by only single leg, and can be rehabilitation and locomotion apparatus.

First claim

What is claimed is:

1. A stepper for a physically-impaired person comprising:
a direction controller comprising:
a front wheel set; and
a steering wheel connected to the front wheel set for turning the front wheel set so that the stepper turns;

a rear wheel transmission comprising:
a gear transmission comprising an active gear, a chain, and a passive gear, the active gear connected to the passive gear via the chain for rotating the passive gear when being rotated; and
a rear wheel shaft comprising a rear wheel set and connected to the passive gear for rotating the rear wheel set when the passive gear is rotated;

a supporting shaft connected to the direction controller and the rear wheel transmission for driving rotation of the front wheel set when the rear wheel set is rotated so that the stepper moves; and
a foot-hand swinging set comprising:
a pedal mounted on two sides of the supporting shaft, one end of the pedal connected to the active gear for rotating the active gear when the pedal is rotated;

a joystick having a handle for grasping, the joystick connected to another end of the pedal for being rotated by the pedal when the pedal is rotated, or for rotating the pedal when being rotated; and
a seat mounted on the supporting shaft and having a seat back, the seat back having a safety belt;
wherein the pedal has a recess and a securing strip, wherein the direction controller further comprises a rotatable shaft connected to the steering wheel for being rotated by the steering wheel when the steering wheel is rotated; and wherein a bar is connected to the joystick and the rotatable shaft, so as to support the foot-hand swinging set.

2. The stepper as claimed in claim 1 , wherein the front wheel set comprises a front wheel connected to the rotatable shaft for being turned by the rotatable shaft when the rotatable shaft is rotated so that the stepper turns; and wherein the rear wheel set has a rear wheel.

3. The stepper as claimed in claim 1 , wherein the front wheel set comprises a front wheel connected to the rotatable shaft for being turned by the rotatable shaft when the rotatable shaft is rotated so that the stepper turns; and wherein the rear wheel set comprises a rear-right wheel and a rear-left wheel both connected to two ends of the rear wheel shaft.

4. The stepper as claimed in claim 1 , wherein the direction controller further comprises a front wheel shaft connected to the rotatable shaft for being turned by the rotatable shaft when the rotatable shaft is rotated; and the front wheel set comprises a front-right wheel and a front-left wheel, the front wheels connected to two ends of the front wheel shaft for being turned by the front wheel shaft when the front wheel shaft is turned so that the stepper turns; and wherein the rear wheel set has a rear wheel.

5. The stepper as claimed in claim 1 , wherein a front wheel shaft is connected to the rotatable shaft for being turned by the rotatable shaft when the rotatable shaft is rotated; and the front wheel set comprises a front-right wheel and a front-left wheel, the front wheels connected to two ends of the front wheel shaft for being turned by the front wheel shaft when the front wheel shaft is turned so that the stepper turns; and wherein the rear wheel set comprises a rear-right wheel and a rear-left wheel both connected to two ends of the rear wheel shaft.

6. The stepper as claimed in claim 1 , wherein the handle has a hoop-and-loop fastener for detachable connection to a glove.

7. The stepper as claimed in claim 1 , wherein the handle has a hoop-and-loop fastener for detachable connection to a glove, and a thumb portion and an index finger portion of the glove are connected to form a sleeve for inserting the handle thereto and connecting the handle.

8. The stepper as claimed in claim 1 , wherein the handle levels with the steering wheel.

9. The stepper as claimed in claim 1 , further comprising:
a brake connected to the direction controller and the rear wheel transmission.
