A pet door according to claim 1 wherein the recessed marginal portion provides two step-downs, located one to either side of a flap closing position, and thereby providing two clearances to prevent paw trapping when the flap is displaced for opening the door in either direction relative to the closing position.
Claim 7
Dependent Claim

A pet door, comprising: a frame member defining an aperture; a rigid flap swingably mounted at an upper portion of said aperture for the opening and closing thereof; a flap securing mechanism; and a tunnel formation associated with said frame member and projecting laterally therefrom, said tunnel formation including a marginal portion located adjacent a free edge of said flap and extending laterally therefrom, said tunnel formation being stepped to provide an enlarged clearance between said tunnel and said flap when said flap is displaced into said tunnel thereby precluding trapping of a pet's paw between said flap and said tunnel formation.
Claim 8
Dependent Claim
102 words
A pet door, comprising: a frame member defining an aperture; a rigid flap swingably mounted at an upper portion of said aperture for the opening and closing thereof; a flap securing mechanism; and a tunnel formation associated with said frame member and projecting laterally therefrom, said tunnel formation including a marginal portion located adjacent a free edge of said flap and extending laterally therefrom, said tunnel formation being stepped to provide an enlarged clearance between said tunnel and said flap when said flap is displaced into said tunnel thereby precluding trapping of a pet's paw between said flap and said tunnel formation.
