Definitions

  • the present invention is particularly suitable for marking individual vehicles such as bicycles, scooters, mopeds or motorcycles. It will be described more particularly in its application to the marking of bicycles, by way of non-limiting example.
  • WO 2012/101369 A1 a more sophisticated and complex method of marking an object such as a bicycle, using a translucent marking part attached and fixed to the bicycle frame.
  • This marking part has a wall which delimits a chamber located between the wall and the surface of the bicycle frame. In this chamber is inserted an identification label.
  • the marking part has two openings giving access to the chamber for the injection and circulation of a translucent glue in order to drown the identification label in the volume of injected glue.
  • This method represents progress in terms of marking security, since the label is protected behind a wall of the marking part and part of the glue is injected.
  • this marking method is much more complex and expensive than previous solutions. It requires the use of consumables such as tubes for injecting glue, which are lost with each use, as well as the excess glue that remains there.
  • the marking device also includes several additional parts, in addition to the marking part itself, such as ribs acting as spacers to position the identification label in the chamber, and baffles arranged inside the chamber to ensure the guidance and proper distribution of the injected glue. Due to the complex structure of the parts used, the marking process using this device is relatively long and therefore expensive.
  • the general aim of the present invention is in particular to propose an improved marking device and method, intended in particular but not exclusively for the identification of bicycles, and capable of eliminating the drawbacks of known marking systems.
  • the invention aims in particular to provide better resistance of the identifier to tearing. It also aims, in the event of tearing after a significant resistance time, for the marking to leave traces of tearing that are very difficult to remove, regardless of the more or less granular or more or less smooth nature of the support. It should be noted that in several countries, the marking of a bicycle can only be legally carried out by professionals, who will hesitate or even give up on reselling a bicycle whose identifier has clearly been torn off.
  • Another object of the invention is to propose a device and a method for installing an identifier which is significantly simpler, faster, more reliable and less expensive than known systems. Furthermore, the installation must require very little handling and without requiring any special skills.
  • Another aim of the invention is to propose a device having a very simple structure, with a very small number of parts, having a long service life, and using little glue and few or no additional consumables.
  • the invention consists in proposing a marking device according to claim 1 consisting of a flexible plastic label previously marked with an identifier, in particular using a laser beam, the label being provided with a frame delimiting a cavity that is filled before fixing the device on its host support, with a resin that can be hardened by polymerization under a UV lamp.
  • This hardenable resin is a two-component resin comprising a mixture of a hardenable resin and a hardening agent, leading to an extremely strong bond between the label and the host support.
  • the lower face of the frame intended to be fixed on a support to be marked comprises on its rear face a thin protective film (also called a "liner" in English terminology) comprising a cutout corresponding to the surface of the cavity.
  • FIG 1 schematically represents a cross-sectional view of an identification device 1 according to the invention. It essentially comprises a label 2 whose lower face has a frame 3 which extends over the periphery of the label so as to delimit a volume or cavity 5 which is intended to be filled by a layer 4 of glue or resin to ensure a very strong bond with a receiving support 10 (visible in figure 3 ), consisting for example of a portion of a bicycle frame.
  • the function of the label 2 is to carry a unique identifier that allows the bicycle or object to be tracked.
  • This may include a unique alphanumeric identifier ( ID1234567890 in the example shown), which is also entered into a database for tracking purposes in the event of theft of the marked bicycle or object.
  • This identifier may be produced in various ways, depending on the material used for the label, and whether it is opaque or translucent.
  • the label 2 is made of polycarbonate (PC), polyethylene (PET), or polyvinyl chloride (PVC).
  • PC polycarbonate
  • PET polyethylene
  • PVC polyvinyl chloride
  • polycarbonate is a plastic material having excellent mechanical properties and thermal resistance allowing use between -100°C and 120°C.
  • it can be treated to resist ultraviolet radiation so as not to weaken the device when the docking support 10 is left outdoors as in the case of bicycles.
  • the identifier can be produced on its upper surface, by printing, or preferably by laser engraving which will reveal the identifier in black.
  • the upper face of the label 2 (the front ), shown in Figure 2A , either covered with a protective varnish (not shown).
  • the identifier can be produced by printing or laser engraving on the lower face of the label, shown in Figure 2B (the back ), or by laser engraving inside the body of the label, during its manufacture in the factory, therefore before installation on a support to be identified. In both cases no protective varnish will be necessary, the marking of the identifier not being exposed to the effects of the environment after the installation of the label.
  • the rear face of the label 2 namely the one opposite the visible front face and accessible after installation, comprises a frame 3 which extends along the periphery of the rear face of the label 2. Its role is to define a volume or a cavity 5 which will be filled with an extremely strong glue which will ensure a very solid connection between the label 2 and a reception support 10, for example a portion of a bicycle frame.
  • Cavity 5 of the label is filled with glue or polymerizable resin directly during its manufacture in the factory, and polymerized just after the device is placed on the host support.
  • the device it is preferable for the device to have a protective layer opaque to UV rays in order to prevent the glue from polymerizing before the device is placed.
  • the frame 3 can be formed by a double-sided adhesive tape, one front face of which will be fixed to the back face of the label 2 and the other face of which will be fixed when the device 1 is placed on the receiving support 10.
  • the adhesion of the back face of the frame 3 to the receiving support 10 will make it possible to hold the identification device 1 in place while waiting for the glue or resin 4 to harden.
  • the frame 3 can be formed as an integral part of the label 2, for example by molding or 3D printing the plastic material of the label 2.
  • the label 2 will for example have a rectangular shape of approximately 60 mm x 20 mm and a thickness of approximately 200 to 300 microns.
  • the frame 3 will have a width of 4 to 5 mm and a thickness of 1 to 1.2 mm. It should be noted that the dimensions in the figures are not to scale, the thicknesses being exaggerated for clarity. Of course, the dimensions of the various components can easily be adapted for the production of identification devices intended for objects other than bicycles or equivalent.
  • the identification device 1 will further comprise on the rear face of the frame 3 a thin protective film 6, in particular made of Teflon, also called a "liner" in English terminology, fixed using a light adhesive that will allow the protective film 6 to be easily peeled off by hand just before installing the device.
  • this protective film 6 will have a thickness of the order of 0.08 to 0.1 mm and will simply protect the adhesive rear face of the frame 3 when filling and smoothing the glue 4 in the cavity 5.
  • the protective film 6 will however comprise a cutout corresponding to the entire surface of the cavity 5 so as not to hinder the filling of the cavity 5 with the glue 4.
  • the latter may further comprise a smaller self-adhesive secondary label 8, as shown in figures 1 , 2A , 3 And 5 , bearing the same identification number as the main label 2, and intended to be placed under the latter directly on the reception support 10.
  • the main label 2 is then preferably transparent or translucent and reveals the small secondary label 8 and its identifier at through the main label 2, which allows for additional verification of the authenticity of the main label 2. Furthermore, the secondary label 8 and its identifier will remain visible even after an attempt to tear off or damage the main label 2.
  • identification devices 1 can be aligned and fixed on a board 7 (as shown in figure 4 ), which consists of a sheet of protective film 6, for example in A4 format, on which 10 identification devices 1 have been placed, including 10 labels 2 each with its unique identifier. It will then be sufficient to take the labels 2 individually as needed.
  • the two labels 2 and 8 of the same identification device 1 may be located side by side on a board 7, as shown in figure 5 . This arrangement will facilitate the laser inscription of the same identification number on a main label 2 and a neighboring secondary label 8, during the manufacture of the devices.
  • the self-adhesive secondary label 8 When installing such an identification device 1, the self-adhesive secondary label 8 will first be removed from the board 7 and placed on the support 10. Then the corresponding main label 2, provided with its glue 4, will be removed and placed over the secondary label 8. The secondary label 8 will therefore be under the main label 2 and its hardened glue 4, which has the advantage of having two identification markings at two different levels.
  • the main label 2 is larger and very strong, and it makes it very easy to see its identification number, while protecting the secondary label 8 and its identification number.
  • the two identification numbers (which can be chosen to be identical or not) will be seen simultaneously, and if the main label 2 is opaque, the identification number of the secondary label 8 will only be seen after the main label 2 has been torn off or destroyed.
  • the glue 4 a two-component hardenable resin of a resin based on methyl methacrylate marketed under the reference KEOL-MA 41 M10, and a hardening agent marketed under the reference KEOL-MA 41 M10 HARDENER.
  • the identification device 1 After filling the cavity 5 with this two-component mixture of glue 4 using a suitable gun (typically a mixing gun) and smoothing the glue using a spatula or equivalent, the identification device 1 can be placed against the support 10 and a slight pressure applied to the edges of the identification device 1 at the frame 3 to ensure sufficient adhesion. Then the glue 4 will be dried and polymerized, in particular using an ultraviolet lamp. With the glue indicated, drying will take less than 10 minutes, and the glue will be completely hardened at the latest after 24 hours, ensuring the maximum cohesion sought.
  • a suitable gun typically a mixing gun
  • the invention achieves the set goals. It makes it possible to propose individualized identification devices obtained at low cost and which can be taken on demand from a board comprising a plurality of labels protected by a protective film, and each label and its frame can then be used in connection with a two-component polymerizable resin using a simple UV lamp.
  • the identification device once installed, is very resistant thanks to the choice of two-component hardening resin which becomes very hard and protects the marking itself from external aggression.
  • the main label cannot be removed from the surface to be marked without leaving traces, which helps to deter the theft of bicycles thus marked, and also their concealment or resale, particularly by professionals.
  • the identification device according to the invention is particularly simple to install using a very small installation kit that does not require excess glue or additional consumables such as injection tubes or spacers.
  • the installation process is very simple and very quick (less than 2 minutes), it requires only a few manipulations, in particular no glue injection phase into a chamber, and the preparation steps such as dispensing resin into the cavity can be done on a table or workbench, and not on the bicycle itself.
