IPC: A45D2/00
Abstract: A hair straightening apparatus has two arms pivotably coupled at a hinge, and a central pack disposed between the first and second arms and coupled with the hair styling apparatus at the hinge on a hinge end of hair straightening apparatus. A locking mechanism is disposed within the central pack, wherein the locking mechanism includes a symmetrical, elongate lock arm disposed lengthwise within the central pack. The locking mechanism is selectively operable to lock the first and second arms in the closed position. The central pack defines a longitudinal axis, and the elongate lock arm is movable relative to the central pack between the first and second positions in parallel with the longitudinal axis defined by the central pack.
