Device for automatically closing or opening one or several leaves of an enclosure depending on the internal temperature and on the force of the wind. This device comprises, in combination: a) a time-delayed thermostat including a temperature probe 1 connected to a threshold detector 2 and two circuits for control by levels, one for opening 11 and the other for closing 12; b) an antenna 13 fixed above the ridge of the enclosure to be controlled and the lower end of which is in contact with a movable contact 16 controlling the continuous and complete closure of the leaf or leaves when the speed of the wind exceeds a certain predetermined threshold; c) a double switch 10 actuated by the contact 16 and connected on the one hand to the thermostat and on the other hand to at least one motor 15 making it possible to actuate the leaf or leaves, this double switch 10 making it possible to give priority to the control coming from the antenna 13 to trigger the closure of the leaf or leaves when the speed of the wind exceeds a certain predetermined threshold. <IMAGE> |
