Locking attachment for product display hooks

A product locking device for use in connection with a product display hook, where the product display hook comprises upper and lower wire arms having outer end portions arranged in vertically spaced relation and wherein at least one of said outer end portions has an obstructive element associated therewith, and wherein said lower arm is adapted to support merchandise items for display, which comprises

• (a) a lock body having means at an upper portion thereof for attaching said lock body to said upper arm at a position inward of said obstructive element for pivotal movement about an axis of said upper arm,
• (b) said lock body having a locking slot therein having an open side and being sized and positioned to receive said lower arm,
• (c) a rotor element received in said lock body and rotatable therein through a predetermined angle of rotation,
• (d) a locking arm fixed to and extending outward from said rotor element, and rotatable therewith between “lock” and “open” positions of said rotor element,
• (e) said locking arm having an end portion arranged, when said rotor element is in said “lock” position, to close the open side of said locking slot for securing said lower arm within said slot,
• (f) one of said rotor element and said lock body having a locking recess therein,
• (g) the other of said rotor element or said lock body having a resiliently biased stop element thereon resiliently biased toward said locking recess,
• (h) said resiliently biased stop element being received in said locking recess when said recess and said stop element are rotationally aligned in the “lock” position of said rotor element, to normally prevent rotation of said rotor element out of said “lock” position,
• (i) said rotor element having an axially extending slot therein for reception of a key, and
• (j) a key insertable in said axially extending slot and having an outer surface portion engageable with said resiliently biased stop element to displace said element out of said recess to enable rotation of said rotor element to said “open” position in which said locking slot is open at the side thereof to permit pivotal movement of said lock body away from said lower arm to enable removal of a displayed product therefrom.
