A safety device in a lighting rod comprises a locking member having an engagement section, which interferes with a portion of an operation member and thereby locks the lighting operation of the operation member. The locking member can move in a direction, that intersects with the direction along which the operation member moves. An urging member urges the locking member to a locking direction. The locking member is provided with a lock releasing section, which can be operated in order to move the locking member in a direction, that acts against the urging force of the urging member. The lock releasing section is projected to a position, which stands facing the operating section of the operation member. The lock of the lighting operation is released by operating the lock releasing section of the locking member, and the lighting operation is carried out in this state by operating the operating section of the operation member. The locking member automatically returns to the state of the locking as the operation member returns to its original position.
Dispositif de sécurité pour tige d'éclairage, constitué par un élément de verrouillage bloquant la commande d'éclairage. L'élément de verrouillage se déplace suivant une trajectoire qui coupe celle de la commande d'éclairage. Il comporte un mécanisme de verrouillage qui le pousse en place, et un mécanisme de déverrouillage qui peut être actionné pour le ramener à sa position initiale. Le mécanisme de déverrouillage occupe une position face à la commande d'éclairage. Lorsqu'il est actionné, il repousse l'élément de verrouillage et la commande d'éclairage peut à son tour être actionnée. L'élément de verrouillage revient automatiquement en position de verrouillage lorsque la commande d'éclairage est remise à sa position initiale.
