<p>A pet door assembly 10 for mounting in a structural panel 18, comprises a closure assembly having a frame assembly 11 that defines a passageway suitable for passage of an animal, the frame assembly 11 being configured to be partially received in an opening 16 in the structural panel 18 and including an abutment member 24 capable of being brought into abutment with a surface of the structural panel 18 peripheral to the opening 16, a closure member 44 mounted in the frame assembly 11 to be displaceable by an animal between open and closed positions to open and close the opening 16, respectively, to accommodate the passage of the animal through the opening 16, and a retainer 64 that is configured also to be partially received in the opening 16 in the structural panel 18, and including an abutment member capable of being brought into abutment with an opposite surface of the structural panel 18.The frame assembly 11 and the retainer 64 include a circumferentially arranged interlocking arrangement that is configured so that the frame assembly 11 and the retainer 64 can be urged into locking engagement with each other to sandwich the surfaces of the structural panel 18, peripheral to the opening 16, between the abutment members. The interlocking arrangement is further configured so that the frame assembly 11 and the retainer 64 can disengage from each other when the frame assembly 11 and the retainer 64 are rotated relative to each other.</p> |
