Abstract

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.

Claims

1. 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.

2. The security means of claim 1 wherein said link means comprises a pair of substantially identical links, one near each of said end edges of the panel, further characterized by said first connection means comprising:

(1) a first connector body having an elongated flat and strip-like attachment portion for flatwise overlying securement to the upper surface of said upper shelf along the front edge thereof,

(2) a pair of pintles, one for each of said links, each having an outer end portion received in an upper portion of its link to pivot the link for swinging about said link axis, and

(3) means fixed to said attachment portion defining a pair of pintle holders, one near each end of said attachment portion, in each of which another portion of one of said pintles is confined, said pintle holders being in downwardly and forwardly spaced relation to said attachment portion and disposing said pintles in coaxial relation to one another to define said link axis.

3. The security means of claim 2, further characterized by:

(1) said first connector body further having an elongated supporting portion formed in one piece with said attachment portion, extending lengthwise along said attachment portion and projecting laterally obliquely downwardly and forwardly therefrom,

(2) said pintle holders comprising the end portions of a tube which extends lengthwise along said supporting portion, at the underside of the supporting portion and near a front edge thereof, and

(3) said first connector body being of uniform cross-section all along its length.

4. The security means of claim 3, further characterized in that:

said supporting portion is of arcuate forwardly and upwardly concave cross-section and has on its front surface, extending along its length, a pair of laterally spaced and opposing ledges which can cooperate to hold a card that displays price or similar information.

5. The security means of claim 4, further characterized by:

a second connector body, identical to said first connector body, secured to said lower shelf;

said bracket member being formed in one piece from sheet metal and comprising

(1) a substantially C-shaped body portion that has forwardly projecting, vertically spaced apart upper and lower arms, said groove being in the front portion of said upper arm, and

(2) a substantially flat tab portion projecting from said lower arm and bent out of the plane of said body portion, said tab portion having opposite substantially parallel edges that are engageable with said ledges to secure said bracket to said supporting portion of said second connector body for lengthwise sliding adjustment therealong.

6. The security means of claim 3, further characterized by:

(1) said supporting portion of said first connector body having a laterally upwardly projecting flange extending along the front edge thereof;

(2) an elongated upper edge guard of substantially U-shaped cross-section embracing and secured to the upper margin of said panel along the length thereof, said edge guard having thereon a forwardly and upwardly projecting hooking flange which is releasably engageable with said flange on the supporting member for holding the panel in an edgewise upright restocking position in which its bottom edge is uppermost.

7. A theft-deterring device for deterring removal of more than a predetermined number of articles from conventional racks of store shelves, said device to be attached to at least two of said shelves, an upper shelf and a lower shelf, and comprising:

a first shelf bracket attached to said upper shelf, extending downward in front of said shelf, and having a tube at the lowest point thereof;

a first pair of pins, each inserted into an opposite end of said tube, and extending a short distance out each end thereof;

a pair of toggle links, one end of each link being pivotably attached to each of said first pair of pins;

a transparent panel member sized so as to cover the entire space between said upper and lower shelves except for a continuous gap between said panel member and said lower shelf large enough to allow removal of a predetermined number of items therebetween, said panel member pivotably attached to the opposite ends of said toggle links so as to be swingable open to allow access to all of said articles;

a second shelf bracket, identical to said first shelf bracket, attached to said lower shelf and extending downward in front of said lower shelf; and

at least one upstanding retaining bracket attached to said second shelf bracket, having a notch in the upper edge thereof sized to accommodate a bottom edge of said panel member, the bottom of said notch being located at an elevation above said lower shelf to allow engagement with said bottom edge of said panel member and to require some flexing in the bracket and panel member in order to move said toggle link from an unlocked position, wherein it is offset away from said shelves, to a locked position, wherein it is offset toward said shelves.

8. A theft dterring device as recited in claim 7 futher comprising means on said panel member and said first shelf bracket for releasably locking said panel member open.

9. A theft deterring device as recited in claim 8 wherein said locking means includes:

a laterally upwardly projecting flange extending along the lower front edge of said first shelf bracket;

a forwardly and upwardly projecting hooking flange attached to the upper edge of said panel member, which flange is releasably engageable with said flange on said first shelf bracket for holding the panel member in an edgewise upright restocking position in which its bottom edge is uppermost.
