Abstract: Various embodiments of a tool with a pivoting head and locking mechanism are provided. The tool includes a handle and a head that is pivotable relative to the handle. The tool includes a locking mechanism adjustable between a locked position and an unlocked position. In one embodiment, the locking mechanism is biased toward remaining in the locked position when in the locked position and biased toward remaining in the unlocked position when in the unlocked position. In another embodiment, the locking mechanism includes a rotating switch coupled to a lock shuttle that is offset from a central axis of the handle. In another embodiment, the locking mechanism includes a rotating switch coupled to the lock shuttle, the rotating switch includes a projection configured to engage a retention step of the shuttle.

Abstract: A tool with a pivoting head is shown. The tool includes a locking mechanism that allows the angular position of the head to be locked securely in place once selected by a user. In a specific embodiment, the locking mechanism includes a locking channel positioned in a generally parallel orientation to the axis of rotation of the pivoting head. In a specific embodiment, the locking mechanism includes a biasing component positioned in a generally parallel orientation to the axis of rotation of the pivoting head. The locking mechanism may be used with a variety of tools, such as ratchet wrenches, that allow for repositioning of the head relative to the handle of the tool.
