Pet door assembly
View Patent ↗A pet door assembly that includes a support structure that defines an access opening through which a pet can pass. A connecting arrangement is positioned on the support structure to permit the support structure to be connected to at least one connector fastenable to an inwardly facing surface of a closure frame. A self-closing door is mounted on the support structure to be displaceable between a closed position in which the door closes the access opening and an open position.
1. A pet door assembly which comprises
a substantially planar frame operatively adapted to define an access opening through which a pet can pass between an indoor space and an outdoor space and substantially through a substantially planar operatively moveable closure that is positioned in a closed closure position, the closure defining a plane that at least partially defines the indoor space and the outdoor space, the frame including an interior frame member adapted to be located adjacent the indoor space and an exterior frame member that is adapted to be located adjacent the outdoor space, the interior and exterior frame members adapted to cooperatively define a peripheral channel extending about the frame and opening in a direction substantially parallel to the plane of the closure, each frame member defining corresponding ribs that extend into the channel and away from that member's corresponding adjacent space;
a pair of elongate connectors adapted to be operatively fastened to, and to connect the frame to, respective planar surfaces of the closure that each extend perpendicular to the plane of the closure and cooperatively define an internal corner of a closure frame of the closure, the connectors each defining a series of longitudinally extending ridges that correspond with the ribs of the frame members, each connector being at least partially receivable in the channel, the ridges of each connector being configured to interlock with the ribs of the corresponding frame member when the connectors are urged into the channel; and
a self-closing door that is operatively adapted to be mounted on the frame and to be displaceable between a closed position in which the self-closing door closes the access opening and an open position.
2. A pet door assembly as claimed in claim 1 , in which the self-closing door includes a flap member that is pivotally mounted in the frame.
