  • Patent number: 8573629
    Abstract: A tow bar has first and second bar elements telescopically engaged to slide between an extended configuration and a collapsed configuration. A latch housing mounted on the second bar element pivotally mounts a latch element. A locking sear having a sear locking surface and a sear back surface is pivotally mounted to move between a locking position and an unlocking position. In the locking position, a sear locking surface abuts a latch stop of the first bar element to lock the first and second bar elements in the extended configuration. In the unlocking position, the sear locking surface disengages the latch stop, allowing the first and second bar elements to move to the collapsed configuration.
