Wall entry tunnel for a pet door

摘要

A wall entry tunnel for use with a pet door. The wall entry tunnel extends through a structural feature and forms an enclosed passageway connecting the interior and exterior frames of a pet door. The length of the wall entry tunnel adjusts to fit structural features of various thicknesses. The wall entry tunnel includes modular components that facilitate compact packaging and are readily assembled to construct the enclosed passageway with a perimeter sized to match the size of the pet door opening.

主权项

1. A tunnel for use with a pet door having an interior frame and an exterior frame located on opposing sides of a structural unit, each of the interior frame and the exterior frame defining a through opening, said tunnel comprising:
a first section defining a through opening, said first section adapted to connect to said interior frame such that said interior frame through opening allows entry into said first section through opening, said first section comprising:
a first horizontal wall component having a first end and a second end;a second horizontal wall component having a first end and a second end;a first vertical wall having a first end and a second end, said first vertical wall connectable to said first end of said first horizontal wall component and said second horizontal wall component second end; anda second vertical wall having a first end and a second end, said second vertical wall connectable to said second end of said first horizontal wall component and said first end of said second horizontal wall component; a second section defining a through opening, said second section adapted to connect to said exterior frame such that said exterior frame through opening allows entry into said second section through opening, said second section telescopically connected to said first section, said second section through opening cooperating with said first section through opening to define a passageway, said second section comprising:
a first horizontal wall component having a first end and a second end;a second horizontal wall component having a first end and a second end;a first vertical wall having a first end and a second end, said first vertical wall connectable to said first end of said first horizontal wall component and said second end of said second horizontal wall component; anda second vertical wall having a first end and a second end, said second vertical wall connectable to said second end of said first horizontal wall component and said first end of said second horizontal wall component; wherein said first horizontal wall component first end, said second horizontal wall component first end, said first vertical wall component first end, and said second vertical wall component first end of said first section and said second section each define a first connector; and said first horizontal wall component second end, said second horizontal wall component second end, said first vertical wall component second end, and said second vertical wall component second end of said first section and said second section each define a second connector, said second connectors configured to connect to said first connectors.
