Abstract
Abstract The disclosure is directed to a self-locking merchandise hook for mounting on perforated panel board, preventing accidental dislodgement of the hook from its mounted position. In its most advantageous form, the merchandise hook is a single piece molding of all plastic material, including integral plastic hook and base portions, as well as integral mounting lugs. In other forms, the hook may comprise more than one part. In all forms, a self-locking feature is provided in the form of an upwardly extending, flexible resilient tongue, which overlies the front face of a perforated panel board, on which the merchandise hook is mounted. In order to mount or demount the merchandise hook, the locking tongue must be resiliently deflected by the application of at least modest external force. Although intentional mounting and demounting requires no additional action or manipulation, unintentional dislodgement is virtually eliminated.
