Abstract
A locking arrangement for securing roof bow members of a trailer unit wherein several bow members are mounted at one side wall of the trailer for vertical pivoting and are simultaneously latched at an opposing side wall to prevent vertical movement thereof. The latching mechanism consists of a plurality of locking bar levers which are each pivoted on the opposing side wall to have one end overlie a retaining ring on one end of the bow members. A common actuator rests on top of the opposing wall and is pivotally attached to each of the locking bar levers at their non-overlying end. A shaft is connected by a pivot arm to the actuator and extends vertically downward adjacent the floor of the trailer where it is attached to a pivot handle to cause the locking bar levers to be positioned in either an overlying or non-overlying position with respect to their individual retaining rings.
