Description

The present invention relates to a positioning member for a security sealing device for revealing a break-in on an opening. Moreover, the present invention relates to a holding member for such a safety sealing device. In addition, the present invention relates to a safety sealing device comprising such a positioning member and such a holding member. Furthermore, the present invention relates to a method of manufacturing such a positioning member or such a holding member. The present invention finds particular application in the field of storage and transport, for example to ensure the inviolability of an industrial vehicle door or a container door. The present invention finds particular application in the field of protection of buildings, to ensure the inviolability of doors and windows. A seal or prior art safety seal device generally comprises a positioning member, which comprises a body and a member sometimes referred to as a "nail", and a holding member, which is often in the form of a plug. . When the safety sealing device is in use on an opening mechanism of the opening, the positioning member is immovably connected to the holding member. The rigid nail is passed through an orifice provided in this opening mechanism. The body does not pass through this orifice, which keeps in place the positioning member. Burglary on the opening necessarily involves breaking the nail so as to release the opening mechanism. To reveal if the opening has been broken, an operator must visually check the condition of the nail, in order to detect a possible break. However, the operator must bypass the industrial vehicle or the container and approach the nail to perform this visual check. However, this visual control is not sufficient to guarantee the inviolability of the opening, because it presents the risk of lack of detection, since the breakage of the nail can be made difficult to control by the author of the break-in, for example in Bringing together or gluing the pieces of the broken nail, or even replacing a dummy seal or an identical seal. In addition, this visual control induces risks for the safety of the operator when the industrial vehicle or container is in motion. In addition, a visual check is relatively long, which slows down the flow of goods, especially when an operator has to control a large number of nails, for example in a warehouse or a port terminal. An object of the present invention is to solve, in whole or in part, the problems mentioned above.

To this end, the subject of the invention is a positioning member for a safety sealing device intended to reveal a break-in on an opening, the positioning member comprising a body and at least one limb, the limb comprising a proximal portion. attached to the body and a distal portion extending out of the body to a free end adapted to cooperate with a holding member of the safety seal device. The positioning member is characterized in that it comprises an integrated circuit and an antenna which are connected to form a radio-tag, the integrated circuit and / or the antenna extending inside a substantial part of the distal part. In other words, a device according to the invention comprises a radio-tag whose integrated circuit and / or the antenna in a substantial part of the member or "nail". In the present application, the term "substantial" and its derivatives apply to a functionally indispensable part of an element. Thus, a positioning member according to the invention makes it possible to reveal the rupture of the member by automatic detection operated by a detector designed to interrogate radio tags. In case of break-in, the member is broken, so the integrated circuit and / or the antenna are broken, so that the emissions by the radio-tag become null or too weak to allow their automatic detection by a gantry detection, under which passes the truck or container with the opening. An organ according to the invention therefore ensures the inviolability of the opening. The free end of the distal portion facilitates the establishment of the positioning member according to the invention. According to one embodiment, the integrated circuit is housed at least partially in the body, and the antenna is housed at least partially in the distal portion. Thus, in the event of a break-in, the rupture of the limb involves the breaking of the antenna, so that the emissions by the radio-tag become too weak to allow their automatic detection by a detection portal. Typically, the transmit power of the radio tag decreases by about 80%. According to one embodiment, the integrated circuit is completely housed in the body, the antenna is completely housed in the member, and the body and the member are integral, preferably integral and made essentially of a thermoplastic material. Preferably, the body and the member are made essentially of polypropylene, which makes them easily recyclable. Thus, the integrated circuit and the antenna are invisible and inaccessible to a burglar, which can not fail a positioning member according to the invention. In addition, a positioning member according to the invention has a reduced weight and cost and can have a complex shape, because it can be derived from molding. According to one embodiment, the distal portion is substantially rectilinear. Thus, the distal portion can be easily passed through an orifice provided in an opening mechanism of the opening. Alternatively, and depending on the configuration, this distal portion could for example be at least partially curved. According to one embodiment, the integrated circuit and the antenna are arranged between two sheets made preferably of flexible material. Thus, the assembly of the integrated circuit and the antenna are relatively easy because their connection and their positioning are performed before their respective assemblies, for example by overmoulding, in the body and the member. On the other hand, the subject of the present invention is a holding member for a safety sealing device intended to reveal a break-in on an opening, the holding member defining a receptacle designed to receive a member of a positioning member. as previously discussed, and having connecting means adapted to immovably bond the receptacle to the received member in the receptacle. The holding member is characterized in that it comprises an additional integrated circuit and an additional antenna which are connected to form an additional radio-tag, the additional integrated circuit and / or the additional antenna extending to the inside of the holding member and on a substantial part of the periphery of the receptacle. Thus, if a burglar breaks a holding member according to the invention, the additional integrated circuit and / or the additional antenna are broken, so that when the additional radio-tag is interrogated, its transmissions in response become nil or too weak to allow their automatic detection by a gantry detection, under which passes the truck or the container with the opening. A holding member according to the invention therefore ensures the inviolability of the opening. Such a holding member is therefore particularly effective and enhances the overall level of security of a safety seal device according to the invention. According to one embodiment, the connecting means comprise elastic latching means on the positioning member.

Thus, the assembly of a holding member according to the invention on a positioning member according to the invention is easy, so fast. In addition, an operator can easily verify that this assembly is properly made because the snap produces a characteristic rattling.

According to one embodiment, the connecting means form a pivot connection relative to the holding member. Thus, the manipulation and placement of a holding member according to the invention are easy. In addition, the pivot connection increases the shear seal strength in accordance with ISO 17712: 2003. According to one embodiment, the additional integrated circuit and the additional antenna are arranged between two sheets made preferably of flexible material. In addition, the present invention relates to a safety sealing device which comprises a positioning member as previously exposed and a holding member as previously exposed. Thus, such a safety sealing device according to the invention makes it possible to guarantee the tamperproofness of an opening in a reliable manner, since such a security sealing device necessarily reveals a break-in on this door.

Furthermore, the present invention relates to a method of manufacturing a positioning member as previously exposed or a holding member as previously described. The method according to the invention is characterized in that it comprises the steps of: a) arranging the integrated circuit and the antenna or the supplementary integrated circuit and the additional antenna between two sheets made preferably of flexible material, so as to forming a radio tag set or an additional radio tag set; b) overmolding the radio tag assembly or the additional radio tag assembly respectively in the positioning member or in the holding member. Thus, a manufacturing method according to the invention makes it possible to manufacture a positioning member according to the invention or a holding member according to the invention. The present invention will be well understood and its advantages will also emerge in the light of the description which follows, which is given solely by way of non-limiting example and which is made with reference to the accompanying drawings, in which: FIG. is a perspective view of a device according to a first embodiment of the invention and in service configuration; FIG. 2 is an exploded and transparent perspective view of the device of FIG. 1; FIG. 3 is a perspective view truncated by plane III in FIG. 1; FIG. 4 is a perspective view of a component of the device of FIG. 1; FIG. 5 is a perspective view of a device according to a second embodiment of the invention and before it is put into a service configuration; FIG. 6 is a view similar to FIG. 3 of the device of FIG. 5; and FIG. 7 is a front view of a component of the device of FIG. 5 before it is put into a service configuration. FIG. 1 illustrates a safety sealing device 2, hereinafter referred to as seal 2, which comprises a positioning member 1 and a holding member 50. The function of the seal 2 is, in particular, to reveal a burglary on a not shown sash. such as a truck door or a container door. The positioning member 1 comprises a body 10, a member 30. In Figure 1, the seal 2 is illustrated in the assembled state, that is to say in its service configuration. In this service configuration, the holding member 50 is fixed on the member 30 and the member 30 is integral with the body 10. The body 10 has a flat and generally rectangular shape. The body 10 serves in particular the reference function to perform a visual check if necessary. The shape of the body 10 makes easy its grip by an operator during the assembly of the seal 2. In addition, it is possible to write on the body 10 a number for the visual identification of the seal 2. The member 30, sometimes referred to as "nail", comprises a proximal portion 31 which is fixed to the body 10 and a distal portion 32 which extends outside the body 10 to a free distal end 40 and adapted to cooperate with a holding member 50 seal 2. The distal portion 32 is rigid, which facilitates the establishment of the positioning member 1 on a sash mechanism. The portion of the distal portion 32 visible in Figure 1 has a shape of substantially straight rod and cylindrical circular base and X32 axis, so symmetry of revolution. In the present application, the adjective "proximal" qualifies an element that is relatively close to the body 10, while the adjective "distal" qualifies an element that is more distant. In the present application, the adjective "rigid" designates an element that can be semi-rigid without being flexible, so slightly deformable with a radius of curvature greater than or equal to 10 cm. The body 10 and limb 30 are made so that the distal portion 32 passes through an orifice through which the body 10 does not pass. In the example of the figures, the distal portion 32 passes through a circular orifice 15 mm in diameter, through which the body 10 does not pass. For this purpose, a section of the distal portion 32 by a plane P32 transverse to the axis X32 has a maximum dimension smaller than the maximum dimension of at least one cross section of the body 10 by a plane parallel to the plane P32.

In the example of the figures, the diameter D32 of the distal portion 32 is about 10 mm, while the width W10 of the body 10 is about 75 mm. The diameter D32, which represents a transverse dimension of the distal portion 32, is therefore smaller than the width W10.

Advantageously, a transverse dimension of the distal portion 32 is between 1 mm and 50 mm, preferably between 5 mm and 20 mm. Advantageously, the length L32 of the distal portion 32, shown in Figure 2, is between 1 cm and 50 cm, preferably between 4 cm and 20 cm. In the example of the figures, the length L32 is approximately 75 mm. Thus, the dimensions of a positioning member according to the invention can be selected according to the opening mechanism to secure. As shown in Figure 2, the positioning member 1 comprises an integrated circuit 15 and an antenna 35 are connected to form a radio-tag. The integrated circuit 15 is housed in the body 10. The antenna 35 is housed in the member 30. The antenna 35 extends inside a substantial part of the distal portion 32, in this case on a significant fraction of its length L32. The antenna 35 is formed by a rectilinear electrical conductor, such as a single wire about 0.1 mm in diameter, which is connected to the integrated circuit 15 so as to emit identification signals at a determined distance. The rectilinear shape of the antenna 35 simplifies its manipulation, thus the manufacture of the positioning member 1, and it limits the risks of short circuit that would otherwise involve a more complex shape such as a loop. In the present application, the verb "connect" and its derivatives relate to the transmission of electrical, magnetic or electromagnetic signals. This signal transmission can be carried out with or without a conducting wire and by means of a direct or indirect link, that is to say via one or more component (s). The radio-tag allows unambiguous identification of the positioning member 1 by radio frequency according to the so-called RFID technology (of the English "Radio-frequency identification"). For this purpose, the integrated circuit 15 comprises an electronic unit 16 forming an identification means and a loop 17 forming an antenna whose range is about 15 m. The shapes of the integrated circuit 15 and the antenna 35 are determined according to the end use of the positioning member 1 and the seal 2. The signals transmitted by the radio-tag carry information generated or coded by the Electronic unit 16. The information carrying signals transmitted by the radio tag can then be automatically detected by a not shown detector designed to interrogate radio tags. The integrated circuit 15 can operate in read-only mode or in read / write / rewrite mode. The radio-tag can take any existing form according to the variants developed in the RFID technology. Thus, for example, depending on whether it is passive, active or semi-active, the radio-tag may emit only when it is interrogated by the detector or, alternatively, the radio-tag can transmit data autonomously or record data continuously, to transmit them on request or automatically at regular intervals. The radio tag is designed to transmit at a selected frequency between 100 kHz and 3 GHz. As shown in Figure 4, the integrated circuit 15 and the antenna 35 are arranged between two sheets, in this case two sheets 3 and 4 which are flexible paper with a self-adhesive side and a side covered with glycine to avoid tearing . In FIGS. 2 and 4, the antenna 35 is shown in dashed lines because it is covered by the sheets 3 and 4. However, the antenna 35, the loop 17 and the electronic unit 16 are formed by physically continuous components. . To manufacture the positioning member 1, a manufacturing method according to the invention comprises the steps of: a) arranging the integrated circuit 15 and the antenna 35 between the adhesive faces of the two sheets 3, 4 preferably made of material flexible, so as to form a set 6 of radio-label hermetic; b) overmolding the assembly 6 in the positioning member 1. Advantageously, a first injection makes it possible to mold a first portion of the positioning member 1, so as to have a face provided with not shown raised pins which are distributed around the assembly 6. In practice, this first portion corresponds to a half-slice of the positioning member 1. To keep the assembly 6 still in the mold, the sheets 3 and 4 are held by gluing, suction, gravity or electrostatic force.

Then, the assembly 6 is placed on the tacky side of the sheet 3 in a position determined by these protruding lugs. Then, a second injection molds a second portion of the positioning member 1, which corresponds to the other half-slice of the positioning member 1. In other words, the set 6 of radio-label is overmolded by two injections of synthetic thermoplastic material essentially forming the body 10 and the member 30. The body 10 and the member 30 are made of material.

After molding, the integrated circuit 15 is completely housed in the body 10 and the antenna 35 is completely housed in the distal portion 32 of the member 30. The antenna 35 extends over a substantial portion of the length L32 of the distal portion 32. In the case of overmolding, the material of sheets 3 and 4 must withstand a temperature of up to about 300 ° C. As shown in FIGS. 2 and 3, the holding member 50 has a cylindrical shape with a circular base and an axis X32. The holding member 50 comprises connecting means 51 for immovably linking the holding member 50 to the distal portion 32 of the member 30. The connecting means 51 are mounted in a sleeve 53 belonging to the holding member 50. The holding member 50 and the member 30 are made such that the distal portion 32 passes through an orifice through which the holding member 50 does not pass. In the example of the figures, the distal portion 32 passes through a circular orifice 15 mm in diameter, through which the holding member 50 does not pass. Indeed, the outer diameter D50 of the holding member is about 22 mm, while the diameter D32 of the distal portion 32 is about 10 mm. The connecting means 51 define a receptacle 52 designed to receive the distal end 40 of the distal portion 32. The distal end 40 of the distal portion 32 comprises two frustoconical reductions 41 and 42 which respectively define two axial abutment surfaces 43 and 44. As shown in Figure 3, the distal end 40 has a diameter less than or equal to the diameter of the remainder of the distal portion 32. Thus, the distal end 40 is relatively compact, so that the holding member 50 may have a relatively small outer diameter, so compact.

The connecting means 51 comprise two elastic rings 61 and 62 which comprise respective ridges 63 and 64. The edges 63 and 64 are designed to deform at the passage of the distal end 40 and to cooperate, at rest, respectively with the surfaces. axial abutment 43 and 44, so as to maintain the distal end 40 in the receptacle 52. Thus, the elastic rings 61 and 62 prevent the translation of the distal end 40 along the axis X32. The elastic rings 61 and 62 form elastic latching means of the holding member 30 on the distal portion 32.

The connecting means 51 also form a pivot connection for the distal portion 32 relative to the holding member 50 and around the axis X32. The angular range of this pivoting is not limited because the holding member 50 can rotate freely relative to the distal portion 32. The proximal portion 31 of the member 30 comprises a collar which has the particular function of limiting the forces exerted on the body 10 when the seal 1 is in use. As shown in FIGS. 1 and 3, a groove 36 is made under the rim and on the outer surface of the distal portion 32. The groove 36 forms a frangible cross-section because it has a lower mechanical strength than the body 10, especially when subjected to shear stresses. To put the seal 2 in the service configuration, as illustrated in FIG. 1, an operator passes the distal portion 32 in a not shown orifice provided on an opening mechanism of an opening leaf. Then, the operator places the distal end 40 inside the receptacle 52, then presses the distal portion 32 against the holding member and along the axis X32, until the elastic rings 61 and 62 cooperate. with the axial abutment surfaces 43 and 44, which produces a characteristic click. The seal 2 is then in the service configuration. When the seal 2 is in use and a burglary occurs, the distal portion 32 is broken, for example at the groove 36. Insofar as the antenna 35 extends over a substantial part of the length L32, the rupture of the distal portion 32 necessarily involves breaking of the antenna 35. Indeed, the antenna 35 extends at least over the entire exposed portion of the distal portion 32, namely between the proximal portion 31 and the organ 50.

In this case, the emissions by the radio-tag become null or too weak to allow their automatic detection by a detector. In the absence of a signal detected during the passage of the opening equipped with the seal 2 broke, the detector emits an alert revealing that a break-in has occurred on the opening. Figures 5, 6 and 7 illustrate a safety seal device, hereinafter referred to as seal 102, which is in accordance with a second embodiment of the invention. The seal 102 comprises a positioning member 101 according to the first embodiment of the invention and a holding member 150 according to a second embodiment of the invention. Insofar as the seal 102 is similar to the seal 2, the description of the seal 2, given above in relation to FIGS. 1 to 4, may be transposed to the seal 102, with the exception of the differences set out below. A seal element 102 similar or corresponding, by structure or function, to an element of the seal 2 hereinafter has the same numerical reference increased by 100. Thus defines the positioning member 101, two sheets 103 and 104 , a body 110, an electronic unit 116, a loop 117, an integrated circuit 115, a member 130, a proximal portion 131, a distal portion 132, an antenna 135, a groove 136, a distal end 140, the holding 150 and its outer diameter D150. The positioning member 101 is identical to the positioning member 1, while the holding member 150 differs from the holding member 50. Like the holding member 50, the holding member 150 comprises connecting means 151 designed to immovably link the holding member 150 to the positioning member 101. The holding member 150 defines a receptacle 152 designed to receive the member 130 of the positioning member 101 so that the member 130 passes through an orifice through which the holding member 150 does not pass. The holding member 150 differs from the holding member 50 since the holding member 150 includes an additional integrated circuit 155 and an additional antenna 156 which are connected to form an additional radio-tag.

The seal 102 differs from the seal 2 because the identification code of the seal 102 may be composed by means of an algorithm associating the information contained in the integrated circuits 115 and 155. If a break-in occurs, the identification code of the seal 102 becomes unreadable by a remote detector, which makes the seal 102 tamper-proof. Moreover, the holding member 150 differs from the holding member 50 because the additional integrated circuit 155 and its loop 157 extend to the inside the holding member 150 and on a substantial part of the periphery of the receptacle 152. In this case, as shown in Figure 7, the holding member 150 has a generally cylindrical shape with a circular base. The width W155 of the supplementary integrated circuit 155 is greater than or equal to, for example, approximately 10% greater than the circumference of the holding member 150, that is to say the product of 7c (pi) times the outer diameter. D150.

If the author of a break-in breaks the holding member 150 rather than the member 130 to release the opening mechanism of the opening, a detector can no longer automatically detect the additional radio-tag, which necessarily reveals that the seal 101 has been broken. The inviolability of the seal 101 is doubly guaranteed.

The additional antenna 156 extends inside a lug 158 integrally molded and integral with the holding member 150. The lug 158 extends in a direction opposite to the body 10 and parallel to the axis of the distal portion 132. To manufacture the holding member 150, a manufacturing method 25 according to the invention comprises the steps of: a) arranging the integrated circuit 155 and the antenna 156 between the adhesive faces of the two sheets 103 , 104 preferably made of flexible material, so as to form an assembly 106 of additional radio-tag, the assembly 106 being preferably hermetic; B) overmoulding the assembly 106 in the holding member 150 by polypropylene injection, this synthetic thermoplastic material essentially forming the holding member 150. To keep the assembly 106 immobile in the mold, the sheets 103 and 104 are held by gluing, suction, gravity or electrostatic force.

According to other embodiments of the invention not shown, taken alone or in any technically permissible combination: the limb is simply fixed or bound to the body, rather than secured to the body; for example, the member may be attached to the body by resilient latching means or by fitting; the seal comprises several members and / or several bodies, depending on the type of opening to be secured; the or each limb is curvilinear or sinuous, rather than rectilinear; - The integrated circuit is only partially housed in the body, another part receiving part of the integrated circuit; - The antenna is only partially housed in the distal part, another part receiving part of the antenna; - The integrated circuit is housed at least partially in the member, while the antenna is housed at least partially in the body; - The holding member is formed by a portion of the member which deforms permanently to prevent removal of the distal portion of the orifice provided on the mechanism of an opening; thus, the holding member is integral with the seal, and no longer attached to the seal; the holding member can then be permanently attached to the body or limb.
