Abstract
A method of installing a ventilation device through existing plywood door closures of accesses to attic spaces with roof fans in homes includes a frame with louvers across a central opening closed by two doors hingeably attached to be opened and closed with a hook rod interconnecting with eye bolts on the doors, the entire device being insulated to reduce heat loss during the cooler seasons.
Claims8
A method to provide ventilation in a living structure through a ceiling above which is an attic space having a roof fan pulling air from said space to the outside, wherein there is an access opening through the ceiling to the attic space, the access opening being open and closed with a closure means comprising a panel member, the method comprising:
- (A) providing a ventilating device comprising:
- (i) a frame member having outside dimensions smaller than that of the panel member, two opposite ends and a first surface,
- (ii) a central opening through the frame member,
- (iii) at least one door hingeably attached proximate one end of the frame member swinging outwardly from the frame member to an open position opening the central opening and swinging back to the frame member to a closed position to close the central opening,
- (iv) screen means across the central opening to at least partially obstruct sight through the central opening while allowing essentially unobstructed air flow,
- (v) closure means to hold the door in the closed position, and
- (vi) opening means to allow a person to open the door without climbing;
- (B) cutting an opening through the panel member of a size and shape proximate that of the central opening through the frame member of the ventilating device,
- (C) placing the first surface of the ventilating device against the frame member aligning the central opening with the opening through the panel member, and
- (D) attaching the frame member to the panel member,
A ventilating device comprising:
- (i) a rectangular frame member two opposite ends,
- (ii) a rectangular central opening through the frame member,
- (iii) a pair of doors, a first door hingeably attached proximate one end of the frame swinging outwardly in a first direction from the frame member to an open position and a second door hingeably attached proximate the opposite end of the frame swinging outwardly in the first direction from the frame member to an open position, both doors swinging back to the frame member to a closed position to close in combination the central opening of the frame,
- (iv) screen means across the central opening to at least partially obstruct sight through the central opening while allowing essentially unobstructed air flow,
- (v) closure means to hold the door in the closed position comprising at least one magnet on each door position to engage the frame member when each door is swung to the closed position, and
- (vi) opening means to allow a person to open the doors without climbing comprising a pair of members each having an eye opening, each of the members attached to and extending in the first direction from each of the doors proximate an end furthest away from the hingeable attachment and a hand held rod member at least one and half feet long with a hook on an end.
