Abstract: A method of assembling a hanger assembly for mounting to a fan housing in a building includes, providing a first bracket having a first end and a second end, the first end having a first flange and a second flange, providing a second bracket having a first end and a second end, the second end having a first flange and a second flange. The method further includes inserting the second end of the first bracket in a first direction into a first end of a third bracket, inserting the first end of the second bracket in a second direction, opposite the first direction, into a second end of the third bracket, and coupling at least one spacer to the third bracket, the spacer extends from the third bracket in a third direction, substantially perpendicular to the first direction.

Abstract: A hanger assembly configured to mount a fan housing in a building including a first support having a lower surface and a second support. The hanger includes a body having a first end engageable with the first support and a second end engageable with the second support. The body is connectable to the fan housing to support the fan housing between the first and second supports and is adjustable to change a length defined between the first and second ends. The first end includes an outwardly extending flange, which is engageable with the first support to orient the body and the fan housing relative to the lower surface of the first support and to maintain a predetermined distance between the lower surface of the support and a lower surface of one of the fan housing and the hanger body.

Abstract: Some embodiments of the present invention enable a user to select from different appearances and sound types by providing different door chime assembly housing covers. The housing covers can be different in shape, size, appearance, and/or acoustic property, and preferably can be releasably mounted a housing base. A door chime assembler, manufacturer, or user can therefore select from different door chime assembly appearances and acoustic properties by selecting one of two or more different housing covers. The door chime assembly can employ a number of different features that change the sound quality of the door chime assembly, including a domed or tented housing cover shape, a housing cover having curved edges and corners, an open acoustic chamber unbroken by internal walls, and side wall housing apertures. Other significant advantages are provided by the use of a door chime assembly transformer that is mounted to the door chime assembly housing.
