Abstract
The invention concerns a movement transmission unit and a movement transmission apparatus employing the same. The movement transmission transmits at least two movement components, each possessing one degree of freedom of movement, from an input-side (6) to an output-side (82, 84), which movement then has at least two coupled degrees of freedom of movement, or vice versa. The invention also concerns one transmission unit (2) per input-side (6) degree of freedom of movement, i.e multiple transmission units (2), which are functionally bound together in parallel by means of their respective output sections (8). Each transmission unit (2) possesses an immobile, solidly fixed first section (4). Its input facility is a second section (6), which is bend linked to the fixed first section (4) by means of a unified linkage structure encompassing parts (22, 26, 34; 28, 36) and forming what becomes known as a first “parallelogram linkage”. This is movably linked in the direction of the corresponding degrees of freedom of movement of the transmission unit (2). The second section (6) is so designed, that by means of a second linkage structure, (46, 50, 58, 48, 52, 60), i.e. another &#…
