Pivoting Peg Hook for Single-Item Anti-Sweep Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wire hook displays in commercial environments are vulnerable to theft as multiple items can be easily removed at once, and existing security measures often frustrate legitimate purchases by making it difficult to remove items.
Innovation Solution
A peg hook device with a pivotally mounted head member that moves between a biased and engaged position, allowing single-item removal while preventing multiple items from being taken simultaneously, using the natural sliding action of the leading item to pivot the head member and block further sliding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wire hook displays are used, then items are easily accessible and simple to remove, but multiple items can be swept or removed at once enabling theft
Solution Approach 1:
The head member is made dynamically movable between a first position (allowing item removal) and a second position (blocking subsequent items). The pivotal movement of the head member creates a dynamic security mechanism that automatically transitions from permissive to restrictive state after one item is removed, preventing bulk theft while maintaining ease of legitimate purchase
Solution Approach 2:
The wire hook display is segmented into a fixed mounting portion and a movable head member portion. This segmentation allows the head member to independently pivot and change position, creating distinct functional zones: one that permits removal and another that prevents it, thereby enabling selective access control
2Object-affected harmful factors
If security devices are added to control access to the wire hook, then theft is reduced, but legitimate purchases become difficult and frustrating
Solution Approach 1:
The head member is designed to be self-actuating through the natural sliding action of the item being purchased. As the customer slides an item off the display, the item itself triggers the head member to pivot to the blocking position. This self-service mechanism eliminates the need for additional locking devices, keys, or complex security systems that would frustrate legitimate customers
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively deters theft by requiring single-item removal, maintaining the ease of use for legitimate purchases while enhancing security against bulk removals without additional locking mechanisms.
Implementation Method 1
movement of the head member between the biased position and the engaged position is facilitated by sliding movement of a leading item over the end projection

AI summary
There is provided a display device for supporting a plurality of items for selection by an individual, comprising: at least one elongate member for receiving said items thereon; and a head member pivotally mounted to a free end of the elongate member, the head member having an arm portion and an end projection extending substantially perpendicular to the arm portion: the head member being movable between a biased position wherein the arm portion extends substantially parallel to said elongate member to permit sliding movement of an item past said arm portion and an engaged position wherein the arm portion extends outside of a planar axis of the elongate member to prevent sliding movement of an item past the arm portion; wherein movement of said head member between said biased position and said engaged position is facilitated by sliding movement of a leading item over said end projection.
