Title (EN) ILLUMINATION DEVICE HAVING UNDERGROUND STORAGE POSITION
(FR) APPAREIL D'ECLAIRAGE STOCKE SOUS LE NIVEAU DU SOL
Abstract:
(EN) An illumination device (10) that is stored below ground level when not in use and that extends above the ground when in use. When a motor (54) is activated, the inner housing (12) that carries the light bulb (40) extends axially upwardly from the outer housing (14). When the inner housing (12) reaches its fully extended position, a limit switch (70) shuts off the motor (54). Subsequent reactivation of the motor (54) retracts the inner housing (12) and bulb (40) back into the outer housing (14), and another limit switch (68) shuts off the motor (54) when full retraction has been achieved. A second embodiment has an improved structure that facilitates replacement of the motor, and a third embodiment has a further improved structure that eliminates several parts required in the first and second embodiments.
(FR) Appareil d'éclairage (10) qui est stocké sous le niveau du sol lorsqu'il n'est pas utilisé et qui se dresse au-dessus du sol lors de son utilisation. Lorsqu'un moteur (54) est mis en fonction, le boîtier interne (12) qui contient l'ampoule (40) se prolonge axialement vers le haut depuis le boîtier externe (14). Lorsque le boîtier interne (12) est complètement sorti, un interrupteur de fin de course (70) coupe le moteur (54). Une remise en marche ultérieur du moteur (54) provoque la retraction du boîtier interne (12) et de l'ampoule (40) dans le boîtier externe (14), et un autre interrupteur de fin de course (68) arrête le moteur (54) lorsque la complète retraction est obtenue. Une deuxième réalisation comporte une structure améliorée qui facilite le remplacement du moteur, et une troisième réalisation possède une structure encore améliorée qui élimine plusieurs pièces nécessaires dans les première et deuxième réalisations.
