1. A retractable and ligature resistant hook for supporting a personal article from a vertical support surface, the hook comprising:
a mounting plate, the mounting plate defining a rear planar surface for securement against the vertical support surface;
a pivot arm, the pivot arm being supported by the mounting plate and having a catch defining a terminal end of the pivot arm, the catch being moveable about a pivot axis between a retracted position, an extended position and an over-extended position, the extended position being located between the retracted and over-extended positions; and
a biasing member coupled between the mounting plate and pivot arm and defining a threshold weight, the biasing member biasing the pivot arm into the retracted position, the pivot arm being moveable from the retracted position to the extended position upon application of a weight to the pivot arm up to the threshold weight, the pivot arm being moveable from the extended position to the over-extended position upon application of a weight to the pivot arm in an amount greater than the threshold weight, in the over-extended position the terminal end of the catch being configured to release a personal article supported by the catch.
