ABSTRACT:
A guard for telescopic cardan shafts, especially for agricultural machinery, comprises an open ring nut supported by an annular throat of a collar near a universal joint of the cardan shaft. Each annular sheath of a telescopic part of the guard engages into a seat formed by projections of the nut. Some of the projections have click detents which go into slots of the sheath releasing it. On the ring nut an inner funnel is mounted, inside the plane seats of which, resilient tongues of the ring nut release themselves performing a clamping function for the ring nut. An additional band springs into engagement on an annular zone of the inner funnel thus extending the latter. The additional band can move at an angle to the inner funnel from a position where holes of the band are lined up with holes of the funnel for access, to another position where the holes are offset to prevent access.
