Abstract: A system for managing the unlocking of a device for identifying a commercial item includes at least two elements capable of assuming a locked position in which they enclose the article between them, and an unlocked position. The system includes a device for unlocking the identification device, elements for preventing unlocking, which are activated, and decision elements for deciding whether to deactivate or not deactivate the elements for preventing unlocking. The decision elements are capable of deciding on the basis of the identification or lack of identification of the association of the identification device and the commercial item to which the device is attached.

Abstract: Assembly for protecting a product against theft, includes a first part having a spike intended to pass through the product, and a second part provided in a first zone with an orifice for inserting the spike and locking elements to prevent the spike from being withdrawn after insertion. The second part includes at least one second zone for inserting the spike in a plurality of possible positions, the two parts are assembled with one another and kept in two possible modes of assembly. In a first protection mode, the spike is inserted into the orifice of the second part and the locking elements are activated so that a user cannot separate them without a tool; in a second temporary-assembly mode, the spike is inserted into the second zone and held therein in a temporary-assembly position such that a user can separate the two parts from one another without a tool.

Abstract: The invention concerns a device for marking a commercial article, comprising two separable parts: a first part (12) including an axial spike (14), a second part comprising an orifice for axial insertion of the spike and means for locking the spike inserted in said orifice. One of the parts, referred to as the attachment part, comprises an attachment: member (32) that is able to pivot between a first position in which a free end of the member is far away from the attachment part and a second position in which the free end is disposed in a housing (50) of the attachment part. The attachment part is configured so that the free end (32a) of the attachment member is blocked in the housing (50; 108) by the presence of the other part of the device that is locked to the attachment part by way of the spike (14) and its locking means.

Abstract: A device (1) for magnetically unlocking an assembly (10) for protection against theft of a packaged or unpackaged item includes a housing (3), containing at least one permanent magnet (4, 5, 6), and an unlocking surface (4a) for receiving a protective assembly (10) made up of two portions (14, 30) locked with each other to a packaged or unpackaged item so as to proceed to the magnetic unlocking of both portions (14, 30) of the protective assembly (10). The device (1) is characterized in that it includes, on the unlocking surface (4a), a mechanical stabilization element (50) for stabilizing the protective assembly according to a predetermined orientation. The predetermined orientation enables the magnetic field (B), generated by the at least one permanent magnet (4, 5, 6) in a manner perpendicular to the unlocking surface (4a), to magnetically unlock both portions (14, 30) of the protective assembly (10).

Abstract: A device for marking an article with a view to identifying same includes an information display area, a medium for storing the information to be displayed (26), a programmable clock (42), an electrical power supply system (44), a selection element (38, 40, 40a, 22b) for selecting information from the storage medium in order to display same in a display area and an element for attaching the device to the article or packaging thereof, wherein the selection element is enabled at one or more moments programmed into the programmable clock.

The second part includes at least one second zone for inserting the spike in a plurality of possible positions, the two parts are assembled with one another and kept in two possible modes of assembly. In a first protection mode, the spike is inserted into the orifice of the second part and the locking elements are activated so that a user cannot separate them without a tool; in a second temporary-assembly mode, the spike is inserted into the second zone and held therein in a temporary-assembly position such that a user can separate the two parts from one another without a tool.

Abstract: An antitheft device (1) to be attached to an item capable of being stolen and including a control portion (2) that is rotatable relative to an attaching portion (3), the attaching portion (3) including an attaching element (4) that is translatably movable with an unlocked position, for placing of the item into the device (1) and for removing same, and wherein the rotation of the control portion (2) relative to the attaching portion (3) translates the attaching element (4), and with a locked position for maintaining the device (1) on the item and wherein the rotation of the control portion (2) relative to the attaching part (3) does not translate the attaching element (4). The control portion (2) includes a transmission mechanism (15) with a controller for the torque applied to the control portion so that the locked position is achieved for a predetermined value of the torque of forces.

Abstract: An assembly for protecting an item against theft, includes a device (10) for marking the item with a view to identifying same, the device including an area (16) for displaying information, a storage medium (26) in which data to be displayed is stored, elements (22, 24) for selecting data from the storage medium (26) to be displayed in the display area (16), wherein the protection assembly includes a member (14) for attaching the assembly to the item to be protected or to the packaging thereof.

Abstract: A theft-prevention unit (10; 50) for an item, includes a first portion (12) having a spike (16) intended for passing through the item or a packaging containing the item and a second portion (30; 52) provided with an opening (32b; 54b) for inserting the spike and also includes a locking element to prevent the retraction of the spike after the insertion thereof. The two portions are assembled together and maintained in assembled position according to two possible assembly modes: in a first prevention mode, the spike of the first portion is inserted in the opening of the second portion and the locking element is activated such that a user cannot separate the portions without using a tool; in a second provisional assembly mode, the two portions are mutually attached by a provisional attachment member such that a user can separate the two portions from one another without using a tool.
