Description

Appareil de Prise de vues. La presente invention a pour objet un appareil. de Prise de vues comprenant un couvercle articule Sur son boitier par une charniere. Camera. The present invention relates to an apparatus. of Shooting comprising an articulated lid On its case by a hinge.

Dans les appareils de ce genre, de cons- truetion connue, an eprouve toujours de Brandes difficultes ä rendre la charniere etanche ä la lumiere. In devices of this type, of known construction, there is always great difficulty in making the hinge light-tight.

L'appareil selon 1'invention vise ä reme- dier ä cet inconvenient. Il se distingue des appareils connius par 1e fait que la charniere est disposee en dehors de 1a. chambre noire de 1'appareil, celle-ei etant rendue etanche ä la lumiere Sur tout 1e pourtour du eouverele par au moins une nervure .continue et au moins une Borge ininterrompue, previies, l'une Sur Je boitier et 1'autre Sur le couvercle, et desti- n6es ä s'engager l'une dann 1'autre lors de la fermeture du couvercle. The apparatus according to the invention aims to remedy this drawback. It is distinguished from known devices by the fact that the hinge is arranged outside the 1a. dark room of the apparatus, the latter being made light-tight all around the lid by at least one continuous rib and at least one uninterrupted edge, one on the casing and the other on the lid, and intended to engage one dann 1'autre when closing the lid.

Le dessin annexe montre, ä titre d'exem- ple, une forme d'execution de 1'appareil selon 1'invention. The accompanying drawing shows, by way of example, one embodiment of the apparatus according to the invention.

La fig. 1 en est une vue partielle en plan, le couvercle etant ouvert, et la fig. 2 est une coupe par II-II de la fig. 1. fig. 1 is a partial plan view, the cover being open, and FIG. 2 is a section through II-II of FIG. 1.

Cet appareil de Prise de vues comprend an boitier 1. Sur lequel est artieule, par une eharniere 2, un eouverele 3. This camera comprises a box 1. On which is articulated, by a hinge 2, a hinge 3.

Comme cela est visible Sur la fig. 1, la eharniere 2 est disposee en dehors de la chambre noire 1. En effet, cette chambre noire 4 est limitee par une nervure continue 5 formee Sur 1e pourtour du boitier 1, nervure qui contourne 1'espace occupe par la ehar- niAre 2. As can be seen in fig. 1, the harness 2 is arranged outside the darkroom 1. Indeed, this darkroom 4 is limited by a continuous rib 5 formed on the 1st periphery of the case 1, a rib which circumvents the space occupied by the harness 2 .

Le couvercle 3 presente, lui, une Borge ininterrompue 6 contournant eile aussi 1'es- pace oecupe par la charniere 2. The lid 3 has an uninterrupted border 6 also bypassing the space occupied by the hinge 2.

En plan, la nervure 5 et la Borge 6 ont une forme pareille et lors de la fermeture du eouverele 3, la nervure 5 vient s'engager dann la Borge 6, ce qui forme une chicane suffi- sante pour empecher 1'entree de la lumiere clans la chambre noire 4. In plan, the rib 5 and the Borge 6 have a similar shape and when the hinge 3 closes, the rib 5 engages in the Borge 6, which forms a baffle sufficient to prevent the entry of the light in the darkroom 4.

De plus, pour ameliorer encore 1'etan- cheite, 1e bord interieur de la Borge 6` est encore prolonge par une nervure 7 (voir fig. 2) formant en quelque Sorte un second ecran. In addition, to further improve the seal, the first inner edge of the Borge 6` is further extended by a rib 7 (see FIG. 2) forming a sort of second screen.

En variante, la nervure 5, au lieu d'etre formee Sur 1e bord du boitier 1, pourrait eire prevue Sur 1e couvercle 3. La Borge 6 serait alors amenagee dans 1e bord du boi- tier 1. Alternatively, the rib 5, instead of being formed on the edge of the box 1, could be provided on the cover 3. The rib 6 would then be provided in the edge of the box 1.

Dans une autre forme d'exkution, an pourrait prevoir plusieurs ,groupes de ner v ures et rainures Sur 1e pourtour du boitier et du eouverele et cooperant entre eux poiir ga rantir une etancheite parfaite de la cham- bre noire. Il est bien entendu, de plus, que 1a seetion des nervures et rainures pourrait etre autre que celle representee au dessin. In another form of execution, one could provide several groups of ribs and grooves on the periphery of the case and the lid and cooperating with each other to guarantee perfect sealing of the dark chamber. It is understood, moreover, that the setion of the ribs and grooves could be other than that shown in the drawing.
