(54) | Device with elastic gripping action for elastically locking constituent parts of compasses |
(57) This device for elastically locking constituent parts of compasses has the characteristic
of offering two fixed seats (3A,3B) rigid with the compass structure (1), for housing
an elongate body (9) to be retained, they being spaced apart by a movable intermediate
seat (5) substantially aligned with said fixed seats, the movable seat being present
in a member of transverse axis which axially receives a thrust from elastic means
(11) for creating a central transverse force on the elongate body to give rise to
lateral reactions which produce a gripping effect, said elastic means being able to
be subjected to a thrust in the opposite direction by a manual command, in order to
nullify the gripping effect, as required for inserting or extractingly removing the
elongate body. |
