BOITE ETANCHE A L'EAU, POUR APPAREILS ELECTROTECHNIQUES ET AUTRES.
Les boites étanches à l'eau pour appareils électrotechniques sont généralement pourvues d'un couvercle, dans une rainure circulaire du- quel est placé un anneau de joint. La rainure est formée par deux nervu- res moulées dans le couvercle, l'une étant située à l'intérieur, l'autre à l'extérieur contre la paroi de la boite. Lorsque cette boite est utili- sée dans une installation électrique quelconque, il est très possible qu'à l'endroit où elle doit être montée on doive la placer à l'envers, c'est-à- dire avec le fond 'vers le haut et le couvercle vers le bas, L'humidité et l'eau éventuellement présentes ne coulent alors pas directement le long de la paroi de la boite, mais se rassemblent sur la nervure extérieure du cou- vercle.
Dans des conditions défavorables, par exemple lorsqu'un joint n'est plus étanche, l'humidité peut alors aisément pénétrer dans la boite.
Pour éviter cette possibilité, la boîte suivant l'invention est pourvue d'un rebord faisant saillie vers l'extérieur, sur lequel prend appui le couvercle emboîtant l'arête extérieure de la boite. Toutefois le bord extérieur du couvercle ne' peut s'étendre au delà du rebord en saillie, qu'il doit affleurer extérieurement.
La figure unique du dessin annexé montre à titre d'exemple, une. boite suivant l'invention.
Sur la paroi de la boite 1 est aménagé un épaulement circulaire 2 servant d'appui au couvercle 3 ; nervure extérieure 4 du couvercle prend dans ce cas appui sur l'épaulement extérieur 2\ de la boite. Les côtés exté- rieurs 5 et 6, respectivement du couvercle et de la boite, viennent à fleur l'un de l'autre.
On évite ainsi que l'eau ou de l'humidité puisse demeurer sur la nervure extérieure du couvercle de la boite et pénètre dans cette dernière

WATERPROOF BOX, FOR ELECTROTECHNICAL AND OTHER APPLIANCES.
Watertight boxes for electrical engineering devices are generally provided with a cover, in a circular groove in which a seal ring is placed. The groove is formed by two ribs molded into the cover, one located on the inside, the other on the outside against the wall of the box. When this box is used in any electrical installation, it is very possible that in the place where it is to be mounted it must be placed upside down, that is to say with the bottom facing downwards. top and the cover down. Any moisture and water present do not flow directly along the wall of the box, but collect on the outer rib of the cover.
Under unfavorable conditions, for example when a seal is no longer tight, moisture can easily enter the box.
To avoid this possibility, the box according to the invention is provided with a rim projecting outwardly, on which rests the cover fitting the outer edge of the box. However, the outer edge of the cover cannot extend beyond the projecting rim, which it must be flush on the outside.
The single figure of the accompanying drawing shows, by way of example, a. box according to the invention.
On the wall of the box 1 is arranged a circular shoulder 2 serving as a support for the cover 3; outer rib 4 of the cover in this case bears on the outer shoulder 2 \ of the box. The outer sides 5 and 6, respectively of the cover and of the box, come flush with one another.
This prevents water or moisture from remaining on the outer rib of the box lid and entering the box.
