Anti-shoplifting device for projecting holders

## Abstract

There is disclosed an anti-shoplifting device for projecting holders (4), in particular for the display of blister packs, comprising a first (1) and a second body (2), which are mutually movable between a locked position, in which they define an opening (21) for the passage of a hooked projecting holder, ensured by locking assembly (8, 9, 10), and an unlocked position achieved by unlocking assembly (12, 13, 14, 15) acting on the locking assembly (8, 9, 10). The locked and unlocked positions are such that the device is respectively hooked or removable from the projecting holder (4). Further, the first and second bodies (1, 2) are rotateably coupled in a separable manner by a rotating structure.

## Background
BACKGROUND OF THE INVENTION
(1) Field of the Invention.
The present invention relates to an anti-shoplifting device for projecting holders.
(2) Description of Related Art.
A lot of products of limited dimensions and weight are packaged in such a way to be able to hang them on projecting holders.
This enables greater visibility to be given to the product and the display space to be better exploited inside shops, supermarkets, shopping malls, etc.
In practical terms, the packaging of such products comprises a drilled upper portion, for example a through opening suitable for coupling with a projecting holder that can provide a single rod or a pair of parallel rods for better support.
Although of small dimensions, said products have a certain commercial value, so they are often the objective of thieves. Razor blades for men, for example, are costly in relation to the dimensions thereof, so that many supermarkets, following continuous thefts, do not even display them and supply them to the customer only if requested at the checkout counters.
The alarm sensors of the packages are easily evaded by breaking open the package and removing the products.
The thief can easily remove thousands of products such as razor blades for men, using a simple bag. The same considerations apply to batteries, accessories for mobile phones and the like. Normally, these products are all near the checkout counters, they are sometimes even hidden, as in the case of razor blades for men.
Anti-shoplifting devices are known to be coupled with the projecting holder in such a way as to prevent the removal of the package, for example a blister pack.
A first type of known device consists of a box body with an opening for the passage of the projecting holder, and bolt means for fixing the device to the holder. An external operating member enables the device to be locked and unlocked. It is substantially a type of padlock. This device has the drawback of providing a relatively complex opening/closing device for a device of limited dimensions, said mechanism adding greatly to the weight of the anti-shoplifting device and ensuring a not insignificant cost for each projecting holder.
An anti-shoplifting device is further known that consists of a box body comprising a pair of shells connected by means of a hinge that enables the shells to rotate mutually by about 180°, namely between a closing position in which the shells are superimposed and an open position in which the shells are at 180° in relation to one another.
A “snap” locking means ensures the closure of the device, an external key being provided to unlock the device.
The link between the two shells by means of the hinge limits the maneuverability of the device and therefore the hooking/unhooking rapidity to and from the projecting holder. As the operator is asked to interact often with said device, let the reader think, for example, of the number of people who wish to purchase a packet of razor blades for men in a normal supermarket over the course of a day, convenience of use takes on a fundamental and certainly not insignificant role.
On the one hand, the hinge enables the two shells to be centred in an optimal manner during the closing step (for “snap” locking, centring is essential).
Lastly, anti-shoplifting devices are known comprising two separate couplable parts fixed in a locked position, or coupled substantially by means of a bolt locking mechanism with the drawbacks arising therefrom that have been illustrated above.
BRIEF SUMMARY OF THE INVENTION
The object of the present invention is to make a anti-shoplifting device for projecting holders that is of simple concept, is easy to operate, light, compact and economic, that overcomes the drawbacks of the aforesaid known anti-shoplifting devices.
According to this invention, this object is achieved with an anti-shoplifting device for projecting holders, in particular for the display of blister packs, comprising a first and second bodies, preferably shells that are mutually movable between a locked position, in which they define an opening for the passage of the hooked projecting holder, ensured by locking means, and an unlocked position achieved by unlocking means acting on said locking means, said locked and unlocked position being such that the device is respectively hooked or removable from the projecting holder, characterised in that said first and second bodies are rotatably coupled in a separable manner by means of rotation.
Rotatable coupling occurs through a rotatable coupling means that ensures centring of the two bodies.
Said bodies are preferably shells, thus becoming the box device. Alternatively, other shapes may be contemplated for the device, such as ellipsoidal, cylindrical, or cubic.

DETAILED DESCRIPTION OF THE INVENTION
An anti-shoplifting box device 3 for projecting holders 4, in particular for displaying blister packs, comprises (FIG. 1) a first shell 1 rotatably coupled with a second shell 2, and an opening 21 for the passage of the projecting holder 4.
Said first shell 1 comprises a coupling pivot 5 (FIG. 2) having a shaped end 6 rotatably couplable with a coupling guide 7 of the second shell 2, said guide 7 being housed in a hole 20.
The first shell 1 further comprises latches 8 that are slightly deformable elastically with a lug 9 for coupling with locking seats 10 of the second shell 2 (FIG. 7), which further comprises through holes 11 for inserting the unlocking pins 12 with protrusions 13 of a dual-action key 14 having a grip 15 (FIGS. 2 and 4).
With regard to the operation of the device 3, it will first be considered unhooked from the projecting holder 4 (FIG. 2).
The shells 1, 2 are positioned at about 90° from one another, taking care that the end of the projecting holder 4 embraces the coupling pivot 5 (FIG. 2).
The hole 20 is shaped in such a way as to have a portion that enables the end 6 and a portion with the guide 7 for coupling to be inserted.
The shaped end 6 then engages with the coupling guide 7, then rotating the shells 1, 2 with respect to one another until they are completely aligned, i.e. until the hooking ends 9 couple with the seats 10 mutually locking the shells 1, 2 (FIG. 1).
In this position, the anti-shoplifting device 3 cannot be removed from the projecting holder 4, the held blister packs thus not being removable.
In order to unlock the shells 1, 2, it is sufficient to insert the unlocking pins 12 of the key 14 into the through holes 11 until the protrusions 13 interact with the hooking ends 9 (FIG. 5).
By pressing the key 14 against the device 3, the latches 8 are deformed, disengaging the hooking ends 9 from the seats 10.
The two shells are now free to rotate mutually until they assume the position of FIG. 11, i.e. 90° . It is now possible to separate them, thus uncoupling the device 3 from the projecting holder 4. The blister packs can be removed from the projecting holder 4 (FIGS. 10, 11).
Substantially, the mutual rotational motion of the two shells 1, 2 is exploited to lock the shells 1, 2 and unlock them with the help of the key 14.
The coupling latch 8 and the coupling guide 7 permit perfect centring of the shells 1, 2, ensuring the engagement between the hooking ends 9 and the respective seats 10.
A key 14 that is not single but dual action enables unlocking only with a double pin 12 the actions of which have to be synchronised; two separate pins or the like make opening very difficult, if not impossible, so that the thief has to be provided with a very particular, certainly not common key.
The disclosed device 3 is very light, the locking means 8, 9, 10 being very reduced and therefore taking up little space. Maneuverability is excellent thanks to the rotatable coupling means 5, 6, 7 that is absolutely essentially and therefore not constructively complex.
Said shells 1, 2 can be simple rotatably couplable bodies according to the invention. The shells 1, 2 in fact give the device 3 a box shape for being able to contain the end portion of the projecting holder 4. Alternatively, other shapes may be contemplated for device 3, such as ellipsoidal, cylindrical, or cubic. Said end of the projecting holder 4 may remain outside the device 3, which would thus have a through opening 21, in a locked position, the pivot 5 preventing the disengagement of the device 3 from the hooked projecting holder 4.
