The present invention relates to a technique to ensure an actuation of a locking mechanism comprising locking rod means substantially radially displaceable in a rotary detail, which rod means is both exposed to the gravitation and to centrifugal forces in rotation of the detail which centrifugal forces at a certain angular velocity of the detail will exceed the gravitation holding the locking mechanism in an extended position during the whole turn of rotation of the rotary detail, to, substantially in an upper angular position, make a hit against a stop being partly displaceable. The invention is characterized in that the locking rod means, comprising several mutually independently displaceable plunger elements, during rotation below said angular velocity giving an influence of the centrifugal forces onto each plunger element exceeding that from the gravitation, during each turn of rotation of the detail, will struck with its plunger element against a diametrically opposite plunger element extending from the periphery by influence from the gravitation or directly against a resilient bottom in a recess in the rotary detail. |
