Abstract
A method and apparatus for providing ventilation to a selected structure. The apparatus may include various features such as flexible portions, rigid portions, and assembly portions. Further, various steps may be used to form the structure to achieve selected results, such as monolithic formation, inclusion of various positioning members, and the like.
Claims38
A ventilation system, comprising:
- a housing member having a front face cross-section plane;
- a fan system operable to move a volume of gas downstream positioned relative to said housing member;
- a first door and a second door extending from a first portion of said housing member and downstream of the fan system;
- and
- a door positioning member extending between a first end and a second end, wherein the first end is connected at the first portion of the housing that is upstream of the second end that is connected to a structure downstream of the first portion;
- wherein the door positioning member is operable to allow the first door and the second door to move near one another;
- wherein the door positioning member is operable to move with the first and second door while they are near one another and allow a selected movement of at least one of the first door or the second door, while near one another, passed 90 degrees relative to the front face cross-section plane of the housing member.

A method of ventilating an area with a ventilation system having a fan system positioned relative to a housing with at least a first door and a second door extending from a portion of the housing, comprising:
- providing a housing to define a first cross-sectional area;
- selectively covering at least a portion of the first cross-sectional area with the first door and the second door;
- operating the fan system to selectively move a volume of gas downstream and move the first door near the second door a selected amount;
- connecting a first portion of a door positioning member to a first portion of the provided housing;
- extending the door positioning member between the first door and the second door;
- connecting a second portion of the door positioning member to a structure downstream of the first portion;
- allowing the first door to remain near the second door and move relative to the provided housing with the door positioning member between the first door and the second door;
- allowing movement of the first door and the second door with the door positioning member between the first door and the second door for at least a portion of a range of motion of the first door or the second door;
- and
- positioning the first door or the second door with the door positioning member whereupon ceasing operation of the fan system, both of the first door and the second door are operable to be closed.

A method of providing a ventilation system to a structure, the method comprising:
- providing a first ventilation housing having a first flexible diffuser;
- providing a second ventilation housing have a second flexible diffuser;
- mounting the first ventilation housing near the second ventilation housing within a structural element of the structure;
- selecting a non-zero amount of deformation of at least one of the first flexible diffuser, the second flexible diffuser, or combinations thereof;
- wherein selecting the amount of deformation includes the positioning of the first flexible diffuser near the second flexible diffuser at the structure so that the first flexible diffuser deforms the second flexible diffuser, the second flexible diffuser deforms the first flexible diffuser, or the first and the second flexible diffuser both deform each other when fixed to the structure.
2 more elements
A ventilation system, comprising:
- a housing perimeter defining a first cross-sectional area;
- a housing face member defining a second cross-sectional area and having a door connection region;
- a door assembly including a first door member and a second door member connected to the door connection region, wherein the first door member and the second door member are substantially equal in area to the second cross-sectional area;
- a door positioning system having a member having a first end connected near the door connection region and a second end connected downstream of the door connection region;
- and
- a fan selectively operable to move a volume of gas through the housing face in a downstream direction;
- wherein the fan is positioned relative to the housing perimeter;
- wherein the door positioning system is operable to allow the first door member to move to a selected position substantially parallel to the second door member and allow the first door member to remain in the selected position substantially parallel to the second door member as the first door member and the second door member move during operation of the fan;
- wherein the door positioning system allows the first door member and the second door member to move to a position wherein at least one of the first door member and the second door member is at an angle greater than 90 degrees to a plane defined by the second cross-sectional area and obstructs the motion of either of the doors from moving to a position to allow the first door member and the second door member to return to a closed position with a door closing system.
6 more elements
A method of forming a ventilation system, comprising:
- forming a one-piece housing member having,
- a housing perimeter defining a first cross-sectional area,
- a housing face defining a second cross-sectional area, and
- door members and a door support which together are substantially equal in area to the second cross-sectional area;
- removing the door members from the one-piece housing member;
- moveably attaching the removed door members to the remainder of the one-piece housing member;
- and
- positioning a fan to selectively move a volume of gas downstream past the door members.
