Selective lock mechanism
At any time, the user can switch between free knee and locked knee modes. If the user feels unsafe with the knee being free, for example on settled snow, in high winds, or on uneven ground, to prevent buckling, the knee can be locked.
At other times, such as when standing on a ladder working or when making a golf swing, locking the knee is also convenient.
Hydraulic cylinder system
Conventional hydraulic cylinders make the initial swing heavy, and tiredness soon results. Using special technology, with an initial swing that feels as light as with a pneumatic cylinder, it is now possible to walk easily using hydraulics.
The knee joint has been made still more compact by enabling control of high output even from a small-capacity hydraulic cylinder.
Extension assist spring
While standing, one cause of knee buckling with polycentric knee joints is incomplete extension.
Because the extension assist spring maintains knee extension, even users with low-mobility can walk safely.
