A mechanism is disclosed for effecting the relative angular adjustment of a pair of coupled members (102, 104). A rotor (106) is mounted on an axle (108) that is mounted on one member (104), the rotor having a planar face on one side that has an arcuate groove (112) formed therein such that the radial distance between the groove and the axle varies in a gradual manner with variation in angle about the axle. A pin (114) or the like protuberance is mounted on the other member (102) of the pair so as to enter and be slidingly engaged by groove (112). The arrangement is such that rotation of the rotor causes relative angular movement of the members, but pressure between the members will not cause the rotor to turn. The application of this mechanism to the adjustment of keyboard platforms and monitor supports is disclosed.
L'invention porte sur un mécanisme (100) permettant d'effectuer le réglage angulaire relatif d'une paire d'éléments (102, 104) couplés. Un rotor (106) est monté sur un axe (108) monté lui-même sur un élément (104), le rotor ayant une face plane sur un côté constitué d'une rainure (112) courbe de sorte que la distance radiale entre la rainure et les axes varie progressivement simultanément avec la variation de l'angle autour de l'axe. Une broche (114) ou autre élément saillant est montée sur l'autre élément (102) de la paire de façon à pénétrer et s'engager en coulissant par l'intermédiaire de la rainure (112). Cet agencement est tel que la rotation du rotor provoque le déplacement angulaire relatif des éléments, mais la pression entre les éléments n'entraînera pas la rotation du rotor. L'invention porte également sur l'application de ce mécanisme au réglage de plates-formes de claviers et de supports d'écrans.
