Abstract
A reversible fastening device (50) for reversibly fastening connecting means (51) connecting a first (52) and a second member (53); the connecting means (51) being housed entirely inside the first member (52); and the device (50) being characterized in that, at a first reversible stage, the connecting means (51) are moved from a withdrawn position to an extracted position projecting with respect to the first member (52); and in that the desired reversible fastening of the connecting means (51) connecting the first (52) and the second (53) member is achieved in the extracted position.
Claims19
A reversible fastening device (50) comprising connecting means (51) connecting a first (52) and a second (53) member, said connecting means (51) comprising an elastic gripper housed inside said first member (52) coaxial with a given axis;
- actuating means for transporting and activating said elastic gripper, said actuating means comprising a piston coaxial with and inside said elastic gripper;
- and a mechanism for moving said piston and said elastic gripper, at a first reversible stage, from a withdrawn position to an extracted position projecting with respect to said first member (52) and for moving said piston, at a second stage, subsequent to said first stage, from said extracted position to an intermediate position between said extracted position and said withdrawn position, in order to deform elastically said elastic gripper so as to cause the elastic gripper to engage at least one seat on said second member.
A fastening device (50) as claimed in claim, wherein said actuating means comprises a draw rod (63) connected to said piston (61) by elastic means (66).
