Zusammenfassung: | An improved arrangement for holding a stowable 'tween deck in service position. The 'tween deck is moveable between a substantially vertical stored position and a substantially horizontal service position. A guide path is provided at the side of the ship for guiding the 'tween deck for motion between its stored and service positions. The 'tween deck includes a trunnion member extending outwardly into the guide path from that portion of the 'tween deck which is lowermost when the 'tween deck is in its stored position. The improved holding arrangement according to the invention is located at the upper end of the guide path and includes a pocket formed by an enlargement of the guide path at the upper end thereof, a pawl member positioned between the pocket and the guide path. The pawl member pivotally mounted for motion between a first position blocking the pocket to guide the trunnion member in the guide path, and a second position blocking the guide path to guide the trunnion member from the top of the guide path into the pocket. A readjustment arm is coaxially mounted with the pawl member for pivotal movement in position between the pocket and the guide path between a first position in which a portion of the arm extends into the guide path and in which the arm is undisturbed by motion of the trunnion from the upper portion of the guide path to the pocket and a second position in which a portion of the arm extends into the pocket and in which the arm is undistrubed by motion of the trunnion in the guide path. The arrangement also includes means for releasably securing the readjustment arm in the first and second positions, and spring means connected to the readjustment arm and the pawl member for biassing the pawl member to its first position when the arm is in the first position and for biassing the pawl member to the second poisition when the arm is in the second position. |
