Abstract
A telescoping mast having a latch assembly includes a latch body mountable to a first tube section, a latch mechanism supported by the latch body, a toggle mechanism operatively connected to the latch mechanism, and a latch plate mountable to a second tube section. The latch mechanism includes a pawl member pivotably between an engaged position for interlocking with a corresponding recess in the latch plate to thereby restrict axial movement between the first and second tube sections, and a disengaged position allowing relative axial movement between the first and second tube sections. The toggle mechanism is movable between an over-center locked configuration corresponding to the engaged position of the latch mechanism and an unlocked configuration corresponding to the disengaged position of the latch member.
