Abstract

A door chime assembly with a transformer assembly mounted within an electrical box and proximately to a chime. The transformer assembly including a transformer operably coupled to a bracket. The transformer being insertable into the electrical box such that the bracket and electrical box cooperate to electrically isolate the transformer from the chime. The electrical box having mounting features for securing the door chime assembly in existing and/or new construction.

First claim

What is claimed is:

1. A door chime assembly comprising:
an electrical box comprising a wall defining an interior space and an opening; and
a transformer assembly configured to be coupled to the electrical box, the transformer assembly comprising:
a bracket configured to be coupled to the electrical box; and
a chime mounted to a first side of the bracket;
a transformer coupled to a second side of the bracket opposite the first side of the bracket,
wherein the bracket is configured to at least partially cover the opening of the electrical box to isolate the transformer from the chime.

2. The door chime assembly of claim 1 , the transformer comprising a low voltage portion and a high voltage portion disposed behind the bracket in the interior space of the electrical box.

3. The door chime assembly of claim 1 , the electrical box comprising an attachment element for attaching the electrical box to a frame element in a wall of a building.

4. The door chime assembly of claim 1 , the electrical box comprising an attachment element for attaching the electrical box to construction sheeting of a wall of a building.

5. The door chime assembly of claim 1 , the electrical box comprising:
a first attachment element for attaching the electrical box to a frame element in a wall of a building; and
a second attachment element for attaching the electrical box to construction sheeting of a wall of a building.

6. The door chime assembly of claim 5 , the electrical box comprising a third attachment element for receiving a fastener for attaching the electrical box to a frame element in a wall of a building.

7. The door chime assembly of claim 1 , the electrical box comprising:
a third attachment element for receiving a fastener for attaching the electrical box to a frame element in a wall of a building; and
a second attachment element for attaching the electrical box to construction sheeting of a wall of a building.

8. The door chime assembly of claim 1 , further comprising a switch electrically connected to the door chime via at least one low voltage wire.

9. The door chime assembly of claim 1 , further comprising at least one low voltage input wire and at least one high voltage input wire coupled to the transformer, the at least one low voltage input wire extending from the transformer through an aperture in the bracket.

10. The door chime assembly of claim 9 , the bracket comprising a cover aligned with one side of the aperture and configured to deflect the at least one low voltage input wire extending through the aperture.

11. The door chime assembly of claim 10 , the bracket comprising at least one clip retaining a portion of the at least one low voltage input wire extending through the aperture.
