Abstract

A ventilating exhaust fan has a housing having a top, four sides, and an open bottom forming an air inlet. An exhaust outlet is located in one of the sides. A motor is housed within the housing and a fan is connected to the motor. The exhaust fan is mountable within an opening in a surface. The sides of the housing have a plurality of slots through which restraints can be inserted in order to connect the housing to the surface.

Claims

1. A ventilation exhaust fan for mounting in an opening in a surface, said ventilating exhaust fan comprising:

a housing having a top, four sides and an open bottom;

a motor and a fan housed within said housing, said fan being rotatable by said motor;

an exhaust outlet located in said housing;

a plurality of openings in said sides spaced above said bottom a distance corresponding to a ceiling surface thickness; and

a plurality of restraints, said restraints being removably connectable to said housing through said openings for mounting said housing to said surface.

2. The ventilation exhaust fan of claim 1 wherein said plurality of openings are in the shape of an inverted “

T”

.

3. The ventilation exhaust fan of claim 2 wherein said restraints comprising pre-formed, flat, elongated “

U”

-shaped members having a first portion insertable through any one of said plurality of openings and a second portion perpendicular thereto.

4. The ventilation exhaust fan of claim 2 wherein said restraints comprising pre-formed, flat, elongated “

L”

shaped members having a first portion insertable through any one of said plurality of openings and a second portion perpendicular thereto.

5. The ventilation exhaust fan of claim 2 wherein when said first portion is inserted through one of said plurality of openings, said second portion is releasably connected to a portion of said one of said plurality of openings.

6. The ventilation exhaust fan of claim 1 further comprising a flange extending perpendicularly outwards from each wall at said bottom, said restraints coordinating with said flanges such that when mounted to said surface, a portion of said surface is sandwiched between a portion of said restraint and a portion of said flange.

7. A housing for mounting in an opening in a surface and housing components of a ventilation exhaust fan, including a motor and fan, wherein said housing comprises:

a top, four sides and a bottom, an inlet opening being located in said bottom, and an exhaust outlet being located in one of said top and four sides;

a plurality of openings located in said sides spaced above said bottom a distance corresponding to a ceiling surface thickness; and

a plurality of restraints, said restraints being removably connectable to said housing through said openings for mounting said housing to said surface.

8. A method of mounting the ventilation exhaust fan housing of claim 7 in an opening in a surface comprising:

positioning the housing in said opening such that said bottom is in abutment with one side of said surface;

inserting at least two of said plurality of restraints through at least two of said plurality of openings such that a portion of each of said restraints is in abutment with a second opposite side of said surface.
