Low profile latch and closing panel for pet door
View Patent ↗The present invention provides improved pet doors, systems and related methods that may be used or installed on the fixed panel of a new or existing sliding door, such as a patio door, without interfering with the sliding movement of the companion door by providing a low profile closing panel and latch.
1. In combination, a sliding door and low profile pet door and latch comprising:
a sliding door unit comprising a fixed position panel and a slidable panel,
a frame for mounting said pet door into said fixed position panel,
a removable pet door locking panel for insertion into said frame to prevent passage through said pet door, said pet door locking panel having an angular notch on a side edge near an upper corner thereof, and
a low profile latch assembly for said pet door attached to said frame at an angle corresponding to said notch comprising an elongated movable member having a thickness of not more than about 0.2 inches, and a central bore therein for receiving a mount for movably holding said member against said frame such that said member is capable of sliding movement relative to said mount for insertion into said notch and wherein said slidable panel of said door unit can slide past the low profile latch assembly when said frame is mounted in said fixed position panel.
2. The combination of claim 1 wherein the thickness of said movable member is about 0.19 inch.
3. The combination of claim 1 wherein the thickness of said movable member is about 0.2 inch.
4. The combination of claim 1 wherein the thickness of said movable member is between about 11/64 inch and about 13/64 inch.
5. The combination of claim 1 further comprising a biasing member between said movable member and said mount for holding said movable member in place.
6. The combination of claim 5 further comprising at least one detent in said central bore for engaging said biasing member.
7. The combination of claim 1 wherein said notch has an angle of about 100 degrees from a side wall of said pet door panel, and said movable member is mounted having a complementary angle.
8. In combination, a sliding door and low profile pet door assembly, comprising:
a sliding door unit comprising a fixed position panel and a slidable panel;
a frame for mounting said pet door assembly into said fixed position panel;
a removable pet door locking panel for insertion into said frame, said pet door locking panel having a notch on a side edge near an upper corner thereof; and
a low profile latch assembly attached to said frame at an angle corresponding to said notch, said low profile latch assembly including a slidable member operable to slide in and out of said notch along a plane that is substantially parallel to a vertical plane along which said slidable panel moves within said sliding door unit, wherein said slidable panel of said door unit can slide past the low profile latch assembly when said frame is mounted in said fixed position panel.
9. The combination of claim 8 , further comprising a pet door mounted in said frame that allows passage through said fixed position panel.
10. The combination of claim 8 , wherein said slidable member has a thickness of not more than about 0.2 inches, and a central bore therein for receiving a mount for movably holding said member against said frame such that said slidable 10 member is capable of sliding movement relative to said mount for insertion into said notch.
11. The combination of claim 10 , further comprising a biasing member between said slidable member and said mount for holding said slidable member in place.
12. The combination of claim 10 , further comprising at least one detent in said central bore for engaging said biasing member.
13. The combination of claim 8 , wherein the thickness of said slidable member is about 0.19 inch.
14. The combination of claim 8 , wherein the thickness of said slidable member is about 0.2 inch.
15. The combination of claim 8 , wherein the thickness of said movable slidable member is between about 11/64 inch and about 13/64 inch.
16. The combination of claim 8 wherein said notch has an angle of about 100 degrees from a side wall of said pet door panel, and said slidable member is mounted at about the same angle on said frame.
17. In combination, a sliding door and a low profile pet door assembly comprising:
a sliding door unit comprising a fixed position panel and a slidable panel;
a frame for mounting a pet door into said fixed position panel of a sliding door unit;
wherein said pet door mounted in said frame allows passage through said fixed position panel;
a removable pet door locking panel for insertion into said frame to prevent passage through said pet door, said pet door locking panel having a notch on a side edge near an upper corner thereof, and
a low profile latch assembly for said pet door attached to said frame at an angle corresponding to said notch, wherein installation of said frame and said low profile latch assembly on an inside of said fixed panel of said sliding door unit does not impede the movement of said sliding panel within said sliding door unit and said low profile latch assembly is positioned between said fixed position panel and said sliding panel when said sliding panel is in a fully opened position.
18. The combination of claim 17 , wherein said low profile latch assembly comprises a slidable member having a thickness of not more than about 0.2 inches, and a central bore therein for receiving a mount for movably holding said slidable member against said frame such that said slidable member is capable of sliding movement relative to said mount for insertion into said notch.
19. The combination of claim 18 , further comprising a biasing member between said slidable member and said mount for holding said slidable member in place.
20. The combination of claim 19 , further comprising at least one detent in said central bore for engaging said biasing member.
21. The combination of claim 17 , wherein the thickness of said slidable member is between about 11/64 inch and about 13/64 inch.
