Ventilation fan mounting assembly

An assembly for use in mounting an object in an opening in a structural member, the structural member having opposing first and second surfaces, the assembly comprising:

• a housing that is sized and shaped to define an interior to house the object and that can be received within the opening in the structural member, the housing including:
• a first tab extending from a distal end of the housing, the first tab sized and shaped to be bent to bear against the first surface of the structural member;
• and
• a second tab extending from the distal end, the second tab sized and shaped to engage the second surface of the structural member adjacent the opening and to attach the housing to the structural member;
• wherein the first and second tabs are integrally formed with at least one wall, are co-planar with the at least one wall, and are formed of bendable material that retains a bent shape and can be bent more than once without failure, the first and second tabs having a thickness that enables manual bending of the first and second tabs from an original position to at least an angle of 90 degrees with respect to the at least one wall;
• a trim ring having an upstanding wall extending from a ledge, the upstanding wall is sized and shaped to fit within the interior of the housing;
• and
• a cover having a panel sized and shaped to cover the trim ring, the cover having a connector that releasably connects the cover to the housing, the cover further including at least one standoff extending therefrom that is sized and shaped to bear against the trim ring to hold the trim ring in place.

A ventilation assembly for mounting a ventilation fan in an opening in a structural member without tools, the structural member having opposing first and second surfaces, the assembly comprising:

• a housing that is sized and shaped to define an interior that is capable of housing the ventilation fan, the housing sized and shaped to be slidably received within the opening in the structural member;
• a trim ring capable of attachment to the housing, the trim ring including a circumscribing ledge with an exterior surface and an interior surface, the circumscribing ledge defining a central opening, the trim ring further including an upstanding wall extending from the interior surface of the circumscribing ledge that is sized and shaped to fit within the interior of the housing, wherein the circumscribing ledge on the trim ring is substantially orthogonal to the upstanding wall;
• and
• a cover having a connector that releasably connects the cover to the housing;
• wherein the housing includes:
• a first tab extending from a distal end of a side wall of the housing, the first tab sized and shaped to be bent to bear against the first surface of the structural member;
• and
• a first tab extending from a distal end of a side wall of the housing, the first tab sized and shaped to be bent to bear against the first surface of the structural member;
• and
• a second tab extending from the distal end of the side wall, the second tab sized and shaped to bear against the second surface of the structural member adjacent the opening and to hold the housing to the structural member;
• wherein the first and second tabs are integrally formed with the side wall and are co-planar with the side wall;
• and
• wherein the circumscribing ledge on the trim ring is sized and shaped to extend laterally beyond the first and second tabs on the housing when the first and second tabs are bent.
