Herringbone ladder pivot and locking mechanism
A ladder with a lockable pivot arrangement is disclosed. A lockable pivot arrangement is located and connected between the two elongate ladder portions. And at least two jacks are arranged in each pair of end shells. A pivot mechanism is connected between the end shells that rotate in unison and also allow a pair of end shells to rotate relative to the housing. A locking mechanism within the housing has at least two locking members, each locking member having an actuator, each actuator having a free end. There is an elastic biasing element that biases the two locking members and the corresponding free ends and actuators apart from each other, the positions of the two actuators biased apart allowing single hand actuation to overcome the bias to unlock the rotation of the housing.
公开了一种具有可锁定的枢轴装置的梯子。可锁定的枢轴装置位于并连接在两个细长梯部之间。在每对端壳内部有至少两个插孔。枢轴机构连接在端壳之间，端壳一致旋转，且还允许一对端壳相对于壳体旋转。壳体内的锁定机构具有至少两个锁定部件，每个锁定部件具有致动器，每个致动器具有自由端。有一个弹性偏置元件，其作用是使两个锁定部件以及相应的自由端和致动器偏置而彼此分开，两个致动器被偏置分开时的位置允许单手致动以克服偏置，以对壳体的旋转进行解锁。
