1. An assembly for attaching an information module to a channel of a support surface comprising:
- a first means for contacting a surface of said channel and securely locking thereto;
a second means for pivotally securing the first means to the information module; and
a positioning means connected to the first means;
said positioning means, if placed in a first position, applies a torque which causes said first means to be held in a first position with a width across one dimension of said first means being less than a predetermined value and if said positioning means is placed in a second position, causes said first means to translate from the first position to a second position whereat Said first means is placed in a locking state with the width across said one dimension being greater than the predetermined value.

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.

9. An information device for mounting on a shelf channel to provide shoppers with product information comprising:
-
a housing; a module for displaying product information mounted in said housing; a pair of cams rotatably mounted in spaced relation to one surface of the housing; and a positioning means coupled to the pair of cams;
said positioning means applying torque to keep the pair of cams in an under-center position relative to a reference surface on each one of said pair of cams and being responsive to a force applied in a first direction to rotate the pair of cams until the cams are brought into non-slidable relation with the shelf channel. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A display and information system comprising:
-
a shelf with at least one surface supporting articles for sale and at least one shelf channel in a distal end; a housing; a means for displaying product information mounted in said housing; a device mounted to the housing and operable for locking the housing onto the shelf channel, said device including at least one cam rotatably mounted to the housing and having a periphery displaced at distances R1 and R2 from a center point on said at least one cam wherein R1 is greater than R2 and R1-R2 having a value equivalent to a desired range of shelf channel widths in which the device is to be mounted; and a positioning means connected to the at least one cam and operable to set the cam into a first position whereat the housing is easily inserted in the at least one shelf channel and responsive to an applied force to cause the at least one cam to be brought into contact with a surface of said at least one shelf channel to lock the housing in the at least one shelf channel.
