Definitions

  • the present invention relates to a safety device for miniature bulbs decoration.
  • Garlands and light curtains for illuminations consist of small electric lamps arranged at regular intervals along power cables and mounted directly on them.
  • the device is powered from the mains voltage (usually 230 volts) by a main cable having branches connected in parallel and each formed of a loop on which the lamps are connected in series so as to be individually powered at low voltage.
  • mains voltage usually 230 volts
  • These lamps generally consist of a glass bulb 1 containing a filament 2 whose ends pass through the wall and are directly on the conductors of the power cable 3.
  • the base of the bulb 1 and a portion of the cable 3 are imprisoned in a tube 4 most often silicone coated with a PVC sheath ( Figure 1).
  • the standards in force require that, on the one hand, the live parts can not be touched in case of accidental breakage of the bulb and, on the other hand, that the latter can not be torn off unless a very effort is made. important.
  • the homologation tests for this type of material are carried out by exerting 50 successive tractions of 30 newtons on a bulb.
  • Document US-A-5,632,550.A discloses a device for attaching a bulb to a net network used for producing temporary or permanent lighting decorations, interior or exterior, such as those traditionally installed for the holidays. or other manifestations, these lamps being mounted directly on the power supply cable, the bulb and the end of the cable conductors being enclosed in a double sleeve of translucent transparent or heat-resistant synthetic material.
  • the double sleeve consists of two heat-shrink tubular elements whose length is such that they protrude beyond the front of the bulb to prevent access to live parts and enclose a length of power cable long enough to ensure solid assembly of said bulb and said power cable.
  • the device according to the present invention aims to ensure a high security garlands and light curtains miniature lamps providing protection against tearing of the bulbs and preventing access to the conductive parts thereof when they are broken .
  • FIGS. 2 and 3 consists of a transparent or translucent sleeve 6, colored or not, of heat-resistant synthetic material enclosing both the miniature bulb 1 and the end of the power supply cable 3. in order to make integral the assembly formed by the power cable and the bulbs.
  • the device consists of a molded sleeve 6 on the bulb 1 and the end of the conductors of the cable 3 ( Figure 2).
  • the material constituting the sleeve 6 may be rigid and sufficiently strong to prevent crushing under the conditions of use that may be encountered when using garlands or light curtains. As an indication, it may be polycarbonate or a similar material.
  • This material may, on the contrary, be flexible so as not to split or open in case of crushing.
  • the overmolded sleeve 6 will be calculated so that the tearing of the lamp requires traction greater than 30 newtons.
  • a metal ring 7 or the like clamped on the insulator of the supply cable 3 and crimped in the overmolded sleeve 6.

  1. Sicherheitsvorrichtung für zur Dekoration bestimmte Miniaturglühlampen für elektrische Lampen in Girlanden oder Leuchtvorhängen, die zur Realisierung von in Innenräumen oder im Freien, zeitweilig oder ständig installierten Leuchtdekorationen verwendet werden, wie sie zum Beispiel üblicherweise für das Weihnachtsfest oder sonstige Veranstaltungen installiert werden, wobei diese Lampen direkt auf das Stromversorgungskabel (3) montiert sind, die Glühlampe (1) und die Enden der Leiter des Kabels (3) in einer Fassung (6) aus transparentem oder durchscheinendem, wärmebeständigem Kunststoff eingefasst sind, die, wenn die genannte Glühlampe zerbrochen ist, die Berührung spannungsführender Teile verhindern und deren Herausziehen nur mit sehr großem Kraftaufwand ermöglichen soll, gekennzeichnet dadurch, dass die Fassung durch Überspritzen der Glühlampe (1) und der Leiterenden des Stromversorgungskabels hergestellt wurde.
  2. Vorrichtung gemäß Patentanspruch 1, gekennzeichnet dadurch, dass die überspritzte Fassung (6) aus einem elastischen Werkstoff ist, so dass sie nicht bricht oder sich öffnet, wenn sie gequetscht wird.
  3. Vorrichtung gemäß Patentanspruch 1, gekennzeichnet dadurch, dass die überspritzte Fassung (6) aus einem steifen und ausreichend festen Werkstoff ist, um ein Zusammendrücken unter den auftretenden Einsatzbedingungen zu verhindern.
  4. Vorrichtung gemäß einem der obenstehenden Ansprüche, gekennzeichnet dadurch, dass sie einen Ring (7) besitzt, der auf die Isolierung des Stromversorgungskabels (3) festsitzend montiert und in die überspritzte Fassung (6) gequetscht ist.
  5. Vorrichtung gemäß Anspruch 4, gekennzeichnet dadurch, dass der Ring (7) aus Metall ist.
  6. Vorrichtung gemäß einem der vorstehenden Patentansprüche, gekennzeichnet dadurch, dass die überspritzte Fassung (6) so berechnet ist, dass zum Herausziehen der Lampe eine Zugkraft von mehr als 30 Newton notwendig ist.
  7. Vorrichtung gemäß einem der obenstehenden Ansprüche, gekennzeichnet dadurch, dass die überspritzte Fassung (6) aus einem transparenten oder durchscheinenden, farbigen Werkstoff ist.
