The security device of this invention comprises a transparent panel normally locked edgewise upright in the plane of front edges of a pair of vertically spaced shelves of a selfservice rack, blocking forward removal of all but the lowermost one or a predetermined few of a stack of like articles on the lower one of those shelves. At its top edge the panel has a link connection with the front edge of the upper of those shelves. Its lower edge portion is received in an upwardly opening groove in a fixed bracket, and the bottom of that groove so supports the panel that the link connection cooperates with resilience of the panel and bracket to provide a snap toggle action between locked and unlocked or releasing conditions. From the releasing condition the panel can be raised edgewise out of the groove and swung up to an inverted position and hooked there, permitting free access to the space between the shelves.

Security means cooperable with a pair of vertically spaced shelves which have parallel lengthwise extending front edges and a lower one of which normally supports stacked substantially identical articles that are accessible substantially only from in front of said front edges, for preventing removal of more than a lowermost predetermined number of those articles at a time, said security means comprising: A. a flat panel member having opposite substantially parallel top and bottom edges and opposite end edges and having (1) a length between its end edges that is substantially equal to the length of said shelves and (2) a height between its top and bottom edges that is equal to slightly less than the distance between said shelves minus the height of said predetermined number of said articles; B. link means having upper and lower ends; C. first connection means for so connecting the upper end of said link means with the upper one of said shelves as to provide for swinging of the link means about a link axis which is near and parallel to the front edge of that shelf; D. second connection means connecting the lower end of the link means with the panel member for flatwise swinging of the panel member relative to the link means about a panel axis which is near and parallel to the top edge of the panel member and is spaced from and parallel to said link axis; E. a bracket member securable to the lower one of said shelves and having an upwardly opening groove wherein a lower portion of the panel member is receivable to confine the panel member against swinging about said axes, the bottom of said groove being at an elevation for so supporting the panel member that the panel axis is in horizontally offset relation to the link axis; and F. at least one of said members being sufficiently resilient to permit the link means to be swung about the link axis against yielding bias between a locked position in which the panel axis is rearwardly offset from the link axis and a releasing position in which the panel axis is forwardly offset from the link axis and from which the link means can be swung upward about the link axis to disengage the panel member from said groove and thus free the panel member to be swung forward and upward about the panel axis for unrestricted access to the space between said shelves.
