<p>The seat reservation device has a case covered by a pivoting shutter. This is moved from outside by an appropriate tool and takes an indicator, such as a plate, visible from outside via a window. The control includes an endless screw (13) worked by a movable head (14) engaged by the tool. The screw works with a pinion (7), fixed to the shutter (2) and positioned around its pivot. The shutter forms a receptacle (21) for the indicator (4). At its base is an opening (26) covered by a case wall (12) when the shutter is closed.</p> |
