By lifting and pushing out of sheath, the crutch is ready to be used for several purposes.

[0043] The footrest of the crutch is a wedge 16. It comprises a groove 16a, a step for a second impulse to the side walk 16b, two small holes 16c and 16d with thread, a bigger hole 16e and two bolts 16f and 16g. The wedge could be used as a ramp to overcome obstacles. It is by lifting the spear 7 out of the sheath 2, putting the handle all the way down inside the spear and place the wedge on the floor in front of the wheels. The crutches should be attached to the wheelchair by a coil cord, from the handle to the upper tube closer to the crutch.
