[Class 18] [Also in Group XXV] The cover 1 of a box, which may be an electrical fuse box, is provided with one or more hook like members 11, which engage a pin or pins 10 to prevent the cover falling away during turning about the loose pivotal axis created at the upper edge of the cover support 6. The pins 10 also form stop means for the cover in the open position. Members 11 are preferably formed as extensions of a plate 9 which is arranged to bear against the cover support 6 in the closed position to form a dustproof joint. |
