US12753988 - Safety locking mechanism for elastically expandable baton
The patent describes a safety locking mechanism for an elastically expandable baton that allows the user to securely maintain the baton in a short state or to easily expand it into a long state. The mechanism features a positioning portion, a locking-releasing button, and a safety locking key that work together to prevent unintended expansion while ensuring user control.
Claim 1
1 . A safety locking mechanism applicable to an elastically expandable baton and comprising: a positioning portion configured to be arranged at an outer periphery of an outermost hollow tube of the elastically expandable baton at a position adjacent to a front end of the outermost hollow tube; a locking-releasing button pivotally connectable to the positioning portion, having a locking hook, a slide groove and two ends configured to move as a lever on the positioning portion, and configured to: lock an impact head of the elastically expandable baton through the locking hook and keep the elastically expandable baton in a short-baton state; and release the impact head of the elastically expandable baton through a lever movement when being pressed and allow the elastically expandable baton to be expanded into a long-baton state; and a safety locking key mountable to and bidirectionally slidable in the slide groove of the locking-releasing button, and configured to be slid to a locking position and keep the locking-releasing button from moving as the lever and in a locked state when the elastically expandable baton is in the short-baton state, and be slid to an unlocking position and keep the locking-releasing button in an unlocked state where the lever movement of the locking-releasing button is not blocked by the safety locking key. a positioning portion configured to be arranged at an outer periphery of an outermost hollow tube of the elastically expandable baton at a position adjacent to a front end of the outermost hollow tube; a locking-releasing button pivotally connectable to the positioning portion, having a locking hook, a slide groove and two ends configured to move as a lever on the positioning portion, and configured to: lock an impact head of the elastically expandable baton through the locking hook and keep the elastically expandable baton in a short-baton state; and release the impact head of the elastically expandable baton through a lever movement when being pressed and allow the elastically expandable baton to be expanded into a long-baton state; and lock an impact head of the elastically expandable baton through the locking hook and keep the elastically expandable baton in a short-baton state; and release the impact head of the elastically expandable baton through a lever movement when being pressed and allow the elastically expandable baton to be expanded into a long-baton state; and a safety locking key mountable to and bidirectionally slidable in the slide groove of the locking-releasing button, and configured to be slid to a locking position and keep the locking-releasing button from moving as the lever and in a locked state when the elastically expandable baton is in the short-baton state, and be slid to an unlocking position and keep the locking-releasing button in an unlocked state where the lever movement of the locking-releasing button is not blocked by the safety locking key.
