Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
249 words
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,
Claim 2
Independent Claim
249 words
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,
Claim 3
Dependent Claim
23 words
The method of claim 1 wherein the central opening is rectangular and the cutting through the panel member is of a rectangular opening.
Claim 4
Dependent Claim
25 words
The method of claim 1 wherein the closure means comprises a magnet and closing the door comprises swinging the door upwardly to engage the magnet.
Claim 5
Dependent Claim
50 words
The method of claim 1 wherein the ventilating device comprises a pair of doors, one door hingeably attached proximate one end of the frame and the remaining door hingeably attached proximate the opposite end of the frame, the combination of the two doors closing the central opening of the frame.
Claim 6
Dependent Claim
57 words
The method of claim 1 wherein the opening means comprises a member having an eye opening, the member extending downwardly from the door and a hand held rod member with a hook on an end, and the method further comprises opening the door by engaging the hook in the eye opening and pulling to open the door.
Claim 7
Dependent Claim
85 words
The method of claim 4 wherein the opening means comprises a pair of members each having an eye opening, the members extending downwardly from opposite doors and a hand held rod member with a hook on an end, and the method further comprises opening the doors by engaging the hook on one of the doors in the eye opening and pulling to open the door and then engaging the hook on the remaining door in the eye opening and pulling to open the remaining door.
Claim 8
Dependent Claim
41 words
The method of claim 1 wherein the ventilating device further comprises at least one insulation panel on a surface of the door facing a same direction as the first surface of the frame and the method further comprises opening the door.
Claim 9
Dependent Claim
226 words
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.
Claim 10
Dependent Claim
226 words
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.
