DESCRIPTION DETAILLEE DE L'INVENTION DETAILED DESCRIPTION OF THE INVENTION

[0009] La figure 1 represente un transpondeur 1, ci-apres nomme 'tag', selon l'invention. Le tag 1 comprend deux blocs 2 et3 de forme essentiellement rectangulaire. Deux surfaces laterales et planes 4 et 5 des blocs respectifs sont montees face ä face et essentiellement paralleles l'une par rapport ä l'autre. Les blocs 2 et 3 sont pourvus de protuberances respectives 6 et 7 au milieu de leurs faces superieures, lesdites protuberances etant reliees entre elles par une connexion reglable. Dans la forme d'execution illustree, il s'agit d'une connexion ä vis 10. La rotation d'une rondelle 11 fait tourner un manchon 12 filete, de maniere ä actionner le mouvement axial du manchon 12 par rapport ä un trou filete pourvu dans le premier bloc 2, quand la rondelle 11 est tournee. Une tige 13 connecte le manchon 12 au deuxieme bloc 3. Or, la rotation ä la main de la rondelle 11 actionne le rapprochement ou la Separation des blocs 2 et 3. Cela permet de fixer le tag 1 sur un element adäquat, par exemple allongä, tel qu'une tige arrondie ou plate, en saisissant l'älement allongä entre les surfaces de contact 4 et 5 des blocs 2 et 3 et en serrant la rondelle 11. Figure 1 shows a transponder 1, hereinafter called 'tag', according to the invention. Tag 1 comprises two blocks 2 and 3 of essentially rectangular shape. Two flat side surfaces 4 and 5 of the respective blocks are mounted face to face and substantially parallel to each other. Blocks 2 and 3 are provided with respective protuberances 6 and 7 in the middle of their upper faces, said protuberances being interconnected by an adjustable connection. In the illustrated embodiment, it is a screw connection 10. Rotation of a washer 11 rotates a threaded sleeve 12, so as to actuate the axial movement of the sleeve 12 relative to a threaded hole. provided in the first block 2, when the washer 11 is rotated. A rod 13 connects the sleeve 12 to the second block 3. However, the rotation by hand of the washer 11 actuates the bringing together or the separation of the blocks 2 and 3. This makes it possible to fix the tag 1 on a suitable element, for example elongated , such as a rounded or flat rod, by grasping the elongated element between the contact surfaces 4 and 5 of the blocks 2 and 3 and tightening the washer 11.

[0010] L'attachement du tag 1 ä une branche 15 d'une paire de lunettes est illusträ ä la figure 2. De präfärence, les surfaces de contact 4 et 5 des blocs 2 et 3, i.e. les surfaces qui rentrent en contact avec la branche 15, sont pourvues d'une couche en un matäriau flexible resilient qui permet de fixer le tag 1 en serrant la rondelle 11 jusqu'ä ce que le materiau resilient soit comprime, sans degrader l'esthätique du produit ä proteger. Dans le cas de branches ou tiges ä section ronde et plus ätroite que les blocs, les couches räsilientes vont s'accrocher autour des branches quand la rondelle 11 est serräe, de maniere ä räaliser une fixation ä haute räsistance. [0010] The attachment of the tag 1 to a branch 15 of a pair of glasses is illustrated in FIG. 2. Preferably, the contact surfaces 4 and 5 of the blocks 2 and 3, i.e. the surfaces which come into contact with the branch 15, are provided with a layer of a flexible resilient material which makes it possible to fix the tag 1 by tightening the washer 11 until the resilient material is compressed, without degrading the aesthetics of the product to be protected. In the case of branches or stems with a round section and narrower than the blocks, the resilient layers will cling around the branches when the washer 11 is tightened, so as to achieve a high resistance fixing.

Claims

[0011] The first block 2 further comprises detection and transmission equipment, which makes it possible to manage the presence of the tag 1 on the secure product. Generally, the detection and transmission apparatus comprises a power source, for example a battery, a detection circuit and a circuit for transmitting a signal via a wireless connection. Preferably, the battery is a wireless rechargeable battery. The detection circuit includes at least one electrical switch operable in Tun or the other of two states, called 'connected' or 'disconnected'. The switch is configured as it is in one of two states when the tag is attached to the product. Additionally, the switch automatically changes to the other state when the tag is removed from the product. The transmission circuit may be a wireless communication electronic chip, such as a BLE (Bluetooth Low Energy) chip. The Transmit Circuit is connected to the Detect Circuit and configured to emit a Signal which is related to the state of the switch.

In the form of execution illustrated in the figures, the block 2, which comprises the detection and transmission apparatus, is provided for example with two push buttons 16, positioned at the longitudinal ends of the contact surface 4 of the block 2. The buttons 16 are visible in the front view of the block 2, in figure 3. When the tag 1 is not attached to a product, the buttons 16 come out of the plane of the contact surface. When the tag is installed on a stem or branch of a product, and when the screw connection 10 is tightened, the contact surface 5 of the other block 3 comes into contact with the buttons 16 towards the end of the approximation of the surfaces. of contact. This will depress the two buttons 16 by the fixing force of the tag when the screw connection 10 is tightened. Buttons 16 are connected to two respective switches (not shown) so that pressing or releasing buttons 16 activates either of the 'connected' or 'disconnected' states of the switches. The buttons 16 are provided with a spring or equivalent mechanism, which releases the buttons automatically when the securing force is removed, i.e. when the tag is removed from the product. The detection circuit can then take several forms depending on the embodiment of the switches and their connection. For example, the two switches can be coupled in series, forming part of a single circuit powered by the battery of the detection and transmission apparatus, so that the disconnection of at least one switch,

i.e. releasing at least one push button cuts power or generates an interrupt. This interruption will be detected by the detection circuit and translated into a specific signal by the transmission circuit. Other more complex configurations can be envisaged by those skilled in the art without departing from the scope of the appended claims.

[0013] Securing the product by a tag according to the invention is based on wireless communication between the transmission circuit inside the tag and a receiver device at a distance from the tag but inside the store in which the product is exhibited. For example, a BLE chip is capable of sending a Signal which is receivable by one or more receiving devices such as mobile phones or tablets located within a configurable and defined perimeter around the tag. BLE technology allows the sending from the chip of a sequence of data called an advertising or advertising frame ("advertising" in English terminology) in a continuous manner. Consecutive frames can be coded using an identifier which identifies the product secured by a code, and which corresponds to the state of the buttons, and therefore of the switches.The continuous sending of these advertising frames allows those responsible to continuously manage the presence of the tags on a certain number of products When a tag is removed by an unauthorized person, this change will be immediately represented in the advertising frames and reported on mobile phones or tablets in the form of an auditory alert signal, for example. a digital application which manages the communication with the tags, and which will indicate to the user an identifier of the product from which the tag has been removed, so that the user can go and check the product.

[0014] The transponder according to the invention is easy to remove at the checkout. It suffices to release the screw connection, and to provide that the responsible person who removes the tag can record by his mobile phone or tablet that it is an authorized removal. Surveillance by wireless and local communication, such as by BLE communication, makes it possible to monitor the presence of products in the store without requiring gates at the exit. Customers are able to handle and fetch products in store, without obstruction by wired security.
