  • Patent number: 6773341
    Abstract: A ventilating device for ventilating through a ridge, preferably through a top ridge of a roof, includes a ridge member configured extending longitudinally along and beneath the ridge. The ridge member has a rigid part that includes two opposed panels and a number of cross pieces extending between the opposing panels. The ridge member also has passages extending from a lower part of the ridge member to an upper part of the ridge member. In a first embodiment, the cross pieces extend from the lower part to the upper part of the ridge member transverse to a longitudinal direction of the ridge member, and ventilating passages are formed in spaces between the two opposing panels and between the cross pieces. In a second embodiment, the cross pieces extend between the lower part of the ridge member to the upper part of the ridge member parallel to a longitudinal direction of the ridge member, and ventilating passages are formed as holes penetrating the cross pieces.
