20090078920 | Rigid Telescopic Mechanism - Rigid telescopic mechanism comprised of rigid members and revolute joints in a geometric arrangement which allows for the longitudinal expansion of the mechanism which is characterized by the attribute that the end-member as well as some intermediate members are moving straight and parallel to themselves as well as by the property of the whole structure (a) not to shrink across the transverse direction while the mechanism extends and (b) to possess members which during the extension do not tend to align along the longitudinal axis of the expansion but maintain, instead, diagonal-oblique directions, thus participating in the raising of resistance against transverse and bending loads, consequently reducing the compressive and tensile stresses in the elements of the mechanism (members and joints). Mechanisms of this kind are employed (a) for approaching remote points in space by mechanical means, with the objective of transporting objects, or bearing loads, or moving tools between a base and a remote location whose position may be stationary or variable, (b) for exerting forces and moments at various points located at various distances away from the mechanism's base, (c) in robotic arms with links of varying length, (d) in outer space applications. | 03-26-2009 |
