Abstract

L'invenzione riguarda un collegamento articolato per gambe di un compasso in due parti, ove nella zona del piano di suddivisione una parte presenta frontalmente due linguette esterne che delimitano una fessura e l'altra parte presente una linguetta disposta frontalmente nel centro, che s'impegna in questa fessura, ogni linguetta essendo munita di un'apertura passante per un mezzo di fissaggio che rappresenta l'asse dell'articolazione o snodo ed almeno una parte è in plastica. Questi noti collegamenti articolati presentano, nel caso di una realizzazione in metallo, bordi e punte pericolose, oppure, nel caso di una realizzazione in plastica, sono instabili. Per eliminare questi inconvenienti nonostante l'uso della plastica, è previsto che a) la parte che presenta le due linguette sia in plastica,b) la fessura tra le due linguette sia chiusa su un lato da una parete, e c) la zona d'angolo, rivolta verso questa parete, di una linguetta e la zona d'angolo, opposta a questa parete, di entrambe le linguette sia asportato.The invention relates to an articulated connection for legs of a two-part compass, where in the area of the subdivision plane one part has two external tabs on the front which delimit a slot and the other part has a tab arranged frontally in the center, which engages in this slot, each tongue being provided with an opening passing through a fixing means which represents the axis of the joint or joint and at least a part is made of plastic. These known articulated connections have, in the case of a metal construction, dangerous edges and points, or, in the case of a plastic construction, they are unstable. To eliminate these drawbacks despite the use of plastic, it is envisaged that a) the part which has the two tabs is made of plastic, b) the gap between the two tabs is closed on one side by a wall, and c) the area of corner, facing towards this wall, of one tab and the corner area, opposite to this wall, of both tabs is removed.
