摘要： A ladder locking system that secures an extension ladder to an accessory rack mounted to a vehicle to define a secured position is provided. The secured ladder is prevented from moving fore or aft relative to the rack. The secured ladder is also prevented from moving laterally relative to the rack and vehicle by the downwardly directed force and engagement provided by the locking system. The locking system is movable to a released position wherein the ladder is not engaged by the locking system and thus can be removed from the ladder rack by an operator. An intermediate position occurs when the operator actuates the locking system between the secured and released positions depending upon whether the ladder is being readied for securement in the rack or being readied for removal from the rack.
摘要翻译：提供了一种梯形锁定系统，其将延伸梯固定到安装到车辆上的附件架以限定固定位置。防止固定的梯子相对于机架前后移动。通过由锁定系统提供的向下的力和接合，也可以防止固定的梯子相对于齿条和车辆横向移动。锁定系统可移动到释放位置，其中梯子不被锁定系统接合，并且因此可以由操作者从梯架上移除。当操作者在固定和释放位置之间启动锁定系统时，会发生中间位置，这取决于梯子是否被准备好固定在机架中或准备从机架中取出。
