Definitions

  • the present invention relates to a status indicating device for objects of limited useful life, more specifically to signal the useful life of an object since its first use and if said object has received an impact or strong blow that may have affected its use properties.
  • the actual expiration date does not correspond to the date calculated from the date of manufacture and the useful life of the object, since said actual expiration date is dictated by the date of the first use and the useful life that The object has been assigned in optimal conditions.
  • An example is motorcycle helmets, which calculate their useful life with respect to their use, these helmets being totally unalterable between their manufacture and their sale to the user.
  • the shelf life of said product begins when the user mixes or opens the container, and does not depend on the date of manufacture of the product , being its components more stable separately.
  • This resistance can be significantly diminished when the helmet receives an impact of such intensity that it does not break it, but it can cause cracks and weakening of the conforming material. These impacts can occur, for example, in accidental falls from the hull to the ground.
  • the status indicating device for the purpose of limited useful life, object of this invention has particularities designed to allow a user to know if a product is expired because it has reached the end of its useful life and also warns it that if The object has suffered an impact, such as a fall or similar accident and is not in conditions of optimal use, although externally it does not present marks that show such damage in its structure.
  • the device comprises a housing with an adhesive fixing base on an object, an electrical circuit comprising an electric battery, associated with a switch being located inside said housing. non-reversible operable from the outside of the housing, and then a visual indicator, this visual indicator being appreciable from the outside of the housing, impact detection means and timing means.
  • the user who wishes to control the state of use of a new object, without impacts and in an optimal state, for example a motorcycle helmet without discarding other products, adheres the device on the object in question, and activates it in its First use, using the non-reversible switch.
  • the visual indicator will immediately show that the status is correct until the timing means or the impact detection means deactivate said visual indicator.
  • the impact detecting means turns off the visual indicator when the object receives a considerable impact.
  • the visual indicator also ceases to indicate validity, so it is indicated that the object is no longer safe due to aging.
  • the non-reversible switch comprises a sheet of insulating material disposed between two electrical contacts, said sheet protruding through a groove of the housing for its removal and thus starting the device, when the circuit is closed by the union of both contacts.
  • the timing means comprise a timer programmed with a certain period of time, for example 3 years, the application of the device is stopped in a motorcycle helmet, this timer being connected to the non-reversible switch, being at the output of this connected timer.
  • the timing means are constituted by the whole of the electric battery and the visual indicator, calibrated so that the electric consumption produces the depletion of the electric battery in a determined time when the said electric battery is exhausted by the constant consumption of the indicator visual and the limited electric power capacity of the electric battery.
  • the visual indicator is an LED that indicates the correct state by means of its illumination, and once the device is activated, it turns off and indicates that the object or product is no longer in an optimal state.
  • the visual indicator is a calibrated scaled marker, such as a countdown clock, a progress bar or an indicator with a needle that travels on a scale between a minimum and the maximum lifetime.
  • the impact detection means comprise two concentric conductive rings, joined by at least one frangible conductive filament that, in case of breakage, interrupts the passage of current between the two conductive rings, although other mechanisms that produce the same effect of interrupting the electrical circuit that feeds the visual indicator are not ruled out.
  • Figure 1 shows a sectional view of the device.
  • Figure 2 shows a block diagram of the electrical circuit.
  • Figure 3 shows a schematic view of the impact detection means.
  • FIG. 4 shows a perspective view of a device, in which the visual indicator is a numerical marker.
  • the status signaling device for objects of limited useful life comprises a housing (1) with an adhesive base (1 1) for fixing on an object, being located inside said housing (1) a electrical circuit with a visual indicator (2) appreciable from the outside of said housing (1) to appreciate the signaling of the valid state of the object, within the useful life and without receiving any impact that has diminished its mechanical qualities or operation.
  • the electrical circuit comprises a power supply battery (3), connected to a non-reversible switch (4) operable from the outside of the housing (1) by means of a removable insulating strip (41), following this non-reversible switch ( 4) impact detection means (5) and timing means, the visual indicator (2) being connected, in this case I feel the visual indicator (2) an appreciable LED diode across the housing surface (1 ) translucent, to signal the correct state of the object.
  • the timing means are constituted by a disconnection timer (6) programmed in a specific period of time since its activation by connecting to the electric battery (3), so that once the non-reversible switch (4) is activated, it activates the visual indicator (2) for a maximum programmed time, for example years or a few months.
  • the impact detection means (5) are constituted by two concentric electric conductive rings (51), joined by at least one frangible conductive filament (52) that in an original position enables the passage of electric current between both conductive rings (51) concentric connected to respective poles of the electrical circuit. In the case of an impact, the inertia of the two conductive rings (51) pulls the frangible conductive filament (52), interrupting the electrical circuit.
