Abstract
A pet door includes a motor for locking and unlocking a pet flap of a pet door. The pet flap is rotatably attached to an upper portion of the pet door. The flap has at least one peripheral edge and a movable seal coupled to the flap for reciprocal movement between a retracted position and an extended position. The seal has a second magnetic portion that is magnetically attracted to the first magnetic portion of the frame. The seal is biased to the retracted position when the door is open and the seal being magnetically biased to the extended position by the magnetic force between the first and second magnetic portions when the door is closed.
Claims15
A pet door, comprising:
- a frame defining a passageway therethrough, the frame having a first magnetic portion positioned closely adjacent the passageway;
- a flap pivotally coupled to the frame for movement between a closed position adjacent the frame and an open position away from the frame, the flap having a peripheral edge at least partially defining the flap;
- a movable seal coupled to the peripheral edge of the flap for reciprocal movement between a retracted position proximal the peripheral edge and an extended position distal the peripheral edge, the movable seal having a second magnetic portion that is magnetically attracted to the first magnetic portion of the frame, the movable seal being movable to the retracted position when the door is pivoted to its open position and the movable seal is magnetically moved to its extended position through the magnetic attraction between the first and second magnetic portions when the door is in its closed position, wherein the movable seal includes a mounting flange, a compressible portion extending from the mounting flange that biases the second magnetic portion towards its retracted position, and a holder portion extending from the compressible portion retaining the second magnetic portion.
A pet door, comprising:
- a frame defining a passageway therethrough, the frame having a first magnetic portion positioned closely adjacent the passageway;
- a flap pivotally coupled to the frame, the flap having at least one peripheral edge;
- a movable seal coupled to the flap for reciprocal movement between a retracted position and an extended position, the movable seal having a second magnetic portion that is magnetically attracted to the first magnetic portion of the frame,
- whereby the movable seal is biased to the retracted position when the door is open and the movable seal being magnetically biased to the extended position by the magnetic force between the first and second magnetic portions when the door is closed, wherein the movable seal includes a mounting flange, a compressible portion extending from the mounting flange that biases the second magnetic portion towards its retracted position, and a holder portion extending from the compressible portion retaining the second magnetic portion.

- a seal coupled to the flap for reciprocal movement between a first position adjacent the flap and a second position distal the flap, the seal having a second magnetic portion that is magnetically attracted to the first magnetic portion of the frame to bias the seal to the second position,
- whereby the seal is biased to the first position when the door is open and the seal is magnetically biased to the second position by the magnetic force between the first and second magnetic portions when the door is closed so as to create a seal between the flap and frame, wherein the seal includes a mounting flange, a compressible portion extending from the mounting flange that biases the second magnetic portion towards its first position, and a holder portion extending from the compressible portion retaining the second magnetic portion.
