Abstract
A pet door includes a latch assembly for locking and unlocking a pet flap. The latch assembly has an electric motor, a motor drive shaft having a first end coupled to the electric motor and a second end oppositely disposed from the first end, a drive pin coupled to the second end of the motor drive shaft, and a drive wheel coupled to the drive pin. The drive wheel incrementally rotates with each full rotation of the drive pin. The drive wheel is coupled to a cam drive shaft. The latch assembly also has plurality of latches assemblies coupled to the cam drive shaft for selective engagement of the peripheral edge of the flap depending upon the rotational position of the cam drive shaft, the selective engagement between the latches and the peripheral edge of the flap determining the locking and unlocking of the flap relative to the frame.
