PROVISION OF DRIVING, GUIDANCE AND INTERLOCK FOR A RETRACTABLE SYSTEM OF PROPULSION FOR A BOAT.

摘要

Actuation, guidance and interlocking arrangement for a retractable propulsion system for a vessel comprising a set consisting of a pair of upper arms (18, 18 '') and a pair of lower arms (10, 10 '') articulated with each other to essentially constitute an articulated parallelogram (18, 18 ''; 10, 10 '') connected by its upper joint (16) with vertically movable drive means (15) and connected by its lower joint (9) with the bearing block ( 5) of support of the shaft (3) of the propeller (4) and provided, in its lateral articulations with wedge configuration elements (21, 21 '') intended to be applied in relation to blocking with two fixing elements (13, 13 '') solidarity of the case (1) of the boat and grooved (23, 23 '') corresponding to said wedge configuration. The set of articulated arms (18, 18 ''; 10, 10 '') is locked in an operative position when the upper arms (18, 18 '') are brought to an over-center condition by said drive means (15), once said lateral elements (21, 21 '') are coupled with said fixing elements (13, 13 '').
