Abstract

A low voltage battery powered door mat alarm having an alarm buzzer circuit with mat circuit contact closure by the weight of the pet such as a cat walking across the mat to or from an animal pet door. This activates the buzzer to indicate generally that the pet is approaching the door to go out or has just returned through the pet door with the mat positioned just inside the door so the pet must pass over the mat to go out or come in through the door.

Claims

1. A floor mat indicator for indicating a mat depressing weight thereon such as an animal passing thereover comprising:

first and second electrical conductive means connectable to an electric circuit;

resiliently deflectable structural means normally holding said first and second conductive means apart yet resiliently deflectable by pressure to permit said first and second conductive means to come into electrical conductive contact one with the other; and

an electrical non-conductive enclosure enclosing said first and second conductive means, and said resiliently defectable stuctural means;

wherein said first and second electrical conductive means are first and second conductive material sheets having electrical connections respectively to first and second electrical line leads extended through said electrical non-conductive enclosure from the interior to the exterior thereof;

said resiliently deflectable structural means normally holding said first and second means apart is two planar sheets of electrically insulative plastic that alone hold said first and second electrical conductive material sheets apart yet permit electrical conductive contact between said conductive material sheets when sufficiently resiliently deflected as by an animal walking across said floor mat indicator;

with said first and second electrical conductive material sheets positioned to the outside of said two planar sheets of plastic;

with said two planar sheets of plastic joined together around their peripheral edges; and

wherein openings are provided in said two planar sheets of electrically insulative plastic to permit electrically conductive contact between said conductive material sheets when said two planar sheets of electrical insulative plastic are resiliently deflected together and said first and second conductive material sheets are brought into mutual contact at some location through the general planar extent of said first and second conductive material sheets as would be occasioned by an animal walking across the floor mat.

2. The floor mat indicator of claim 1, wherein said floor mat has electric circuit connection from said first and second electrical conductive material sheets through said first and second electrical line leads to and through a power supply and a signal indicator.

3. The floor mat indicator of claim 2, wherein said signal indicator is a noise generating device subject to generating noise when electric current is passed therethrough.
