  • Dual cam mounting mechanism for electronic shelf edge labels
    Patent number: 5461809
    Abstract: A product information module (such as a shelf tag, shelf label or the like) includes a housing in which a physical embodiment of information is mounted and a locking device which mounts the housing to a support surface. The locking device includes a locking member which coacts with the support surface to form an angle A whose tangent is less than the coefficient of friction between the locking member and the support surface. As a consequence, locking force is minimal and lateral movement of the module is resisted no matter how much force is applied.
