1. A pet-operable chime system, comprising:
- a switch unit comprisinga base plate,a movable plate spaced from said base plate, said movable plate having at least one through hole,a transmitter for transmitting signals,a switch electrically coupled to said transmitter and mounted to either said base plate or said movable plate,an actuation member attached to the other of said base plate or said movable plate that does not support said switch, said actuation member being postitioned at a location that is substantially opposite said switch,at least one spring interconnecting said movable plate and said base plate, wherein said at least one spring is biased to push said movable plate away from said base plate, andat least one post interconnecting said movable plate and said base plate, said post having a first end and an opposing second end, wherein said first end of said post is fixed to said base plate, and said second end of said post is freely inserted through said at least one hole of said movable plate such that said movable plate is free to slide along said post; and
a remote chime unit comprisinga receiver for receiving signals from said transmitter, anda chime electrically coupled to said receiver for generating an audible sound;
wherein said movable plate is movable between a neutral position where no pressure is applied to said movable plate and said actuation member does not engage said switch and an activated position where under pressure said movable plate is moved toward said base plate against the bias of said at least one spring such that said actuation member engages and activates said switch, said activated switch causing said transmitter to send a signal to said remote chime unit to sound said chime.

Abstract
A portable chime system that is operable by a pet to alert the pet owner that the pet desires something such as to be let in or out of a building. The chime system includes a switch unit that may be placed on the ground or floor near a door and which may be activated by a pet applying pressure to the top of the unit. The switch unit is designed to avoid misfiring or nonfiring. The chime system also includes a remote chime unit that can be positioned in a different room or area than the switch unit. When the pet activates the switch unit, the switch unit sends a signal to the chime unit to sound a chime located within the chime unit.
