Abstract (en)
1. A box for protecting an alarm or security device, comprising a support (1) for the alarm device (7) in the form of a rectangular plate (1) disposed vertically and, for the protection of this device, a cover (13, 23) which is pivotally mounted on the support and is normally retained, relative to the latter, in a closed position by means of a shear pin (16, 20) but which may be opened after the breakage, by a manual action, of said pin, by pivoting about a pivot axis which is constituted by two pins (14) provided at the lower end of the cover, characterised in that the cover (13, 23) whose pins (14) are engaged in corresponding slideways (4, 5) formed on the respective vertical edges of the support (1), is retained in the closed position adjacent the upper end by insertion of its upper end edge in a formed-over ledge (6) of the support, and, adjacent the lower end, by the shear pin (16, 20) which is connected to the support and whose breakage under the effect of an impact in the downward direction on the cover causes the downward sliding of the two pins (14) and a corresponding disengagement of the upper edge of the cover out of the ledge (6), so that the cover can then be opened by pivoting it about the two pins.
