Loop member (1) for pointing devices for computers, consisting of a number of axially extending thin wires (11, 12, 13, 15, 16) twined in each other in such a way that the wires (11, 12, 13, 15, 16) work as links that can rotate a small angle in relation to each other. The wires (11, 12, 13, 15, 16) together build up a tangentially bendable cylinder, the cross- section of which is stretched into an elongate shape via two supports. Between the supports, there is a thin plate on which the upper part of the cylinder rests. The upper surface of the cylinder can be reached by a user through an opening in an apparatus box and be moved in a two-dimensional way, the move being detected and giving rise to the corresponding move of a pointer or the like on a screen. Suitable embodiment for said supports and peripheral mechanics is also shown.

Un organe en boucle (1) pour des dispositifs de pointage pour ordinateurs, constitué dun certain nombre de fils fins sétendant axialement (11, 12, 13, 15, 16) entremêlés les uns dans les autres de telle sorte que les fils (11, 12, 13, 15, 16) fonctionnent comme des maillons qui peuvent tourner selon un angle faible les uns par rapport aux autres. Les fils (11, 12, 13, 15, 16) constituent ensemble un cylindre pouvant être courbé tangentiellement, dont la section transversale est étirée en une forme allongée via deux supports. Entre les supports, se trouve une plaque fine sur laquelle repose la partie supérieure du cylindre. La surface supérieure du cylindre peut être atteinte par un utilisateur à travers une ouverture dans un boîtier dappareil et être déplacée de manière bidimensionnelle, le déplacement étant détecté et donnant lieu au déplacement correspondant dun pointeur ou similaire sur un écran. Un mode de réalisation approprié pour lesdits supports et une mécanique périphérique est également présenté.
