Abstract
A telescopic manipulation arm includes a module formed by two segments and a toggle joint. All movements of the toggle joint are transmitted across the module by identical mechanisms in such a way that the friction and inertia are the same for each movement. These mechanisms incorporate shafts positioned equidistantly of an axis in the lower segment and shafts positioned equidistantly of the axis in an upper segment. Shafts are provided for carrying identical pinions, which engage on identical toothed gears, and which are also engaged on substantially identical pinions rotatable with the shafts.

A telescopic manipulation arm, which comprises:
- an external tubular body and an internal tubular body arranged along a common axis and defining therebetween an annular space in which are mounted in parallel and equidistantly of said axis a plurality of first rotary shafts supported in a rotary manner by the external tubular body
- a plurality of second rotary shafts supported in a rotary manner within the internal tubular body, the latter being supported in a rotary manner by an intermediate part so as to be slidable in the external tubular body along said common axis,
- means for controlling translation of the intermediate part in the external tubular body, the intermediate part supporting in a rotary manner first identical pinions, each first pinion being traversed by one of the first shafts and being rotatable with the latter by a first transmission means;
- drive means by which one of the first pinions is rotatable with the internal tubular body wherein each of the remaining first pinions is rotatable with said second rotary shafts;
- the second rotary shafts all each mounted in parallel and equidistantly of said axis, said drive means incorporating second substantially identical pinions fixed to each of the second shafts, and substantially identical toothed gears centered on said common axis and supported in a rotary manner by the intermediate member, each of the toothed gears having an external tooth system engaged on one of the remaining first pinions and an internal tooth system engaged with one of the second pinions.
