Abstract

Claims (18)

1. An adjustable bracket for a window air conditioner comprising:

a base having a platform and an indoor slide base, said base configured to reside atop a sill of a window such that said platform is approximately horizontally disposed once said bracket is installed at a window sill, said indoor slide base coupled to said platform and having a pawl coupled to a ratchet release handle;

an indoor portion having a sliding base configured to slide within said indoor slide base in a first direction perpendicular to the sill of a window; said sliding base further comprising a first leg and a second leg, wherein said first leg further comprises ratchet teeth configured to engage with said pawl;

an outdoor portion configured to slide within said base in a second direction perpendicular to the sill of a window; wherein said indoor portion and said outdoor portion can occupy a retracted position and an extended position with respect to said base.

2. The adjustable bracket of claim 1 , wherein said ratchet release handle further comprises a spring.

3. The adjustable bracket of claim 2 , wherein said pawl further comprises a body and a free end.

4. The adjustable bracket of claim 3 , wherein said ratchet release handle is coupled to said pawl via a connecting rod.

5. The adjustable bracket of claim 4 , wherein each of said ratchet teeth further comprise a first surface and a second surface, said first surface and second surface forming a ridge at a free end of said ratchet teeth and forming a valley at a base end of said ratchet teeth.

6. The adjustable bracket of claim 5 , wherein said free end of said pawl can occupy a locked position and an unlocked position, wherein in said locked position said free end resides in said valley and abuts said first surface of said ratchet teeth, and in said unlocked position said free end is not in contact with said ratchet teeth.

7. The adjustable bracket of claim 6 , wherein said spring has a spring bias force that biases said pawl into said locked position.

8. The adjustable bracket of claim 7 , wherein said unlocked position occurs when a force is applied to said ratchet release handle acting against said spring bias force.

9. The adjustable bracket of claim 7 , wherein said indoor portion is movable from said extended position to said retracted position by pushing said sliding base toward said base, but said indoor portion is movable from said retracted position to said extended position only by applying a force to said ratchet release handle opposing said spring bias force.

10. The adjustable bracket of claim 5 , wherein said pawl further includes a first pawl and a second pawl, wherein said first pawl is situated at a first side of said indoor slide base and said second pawl is situated at a second side of said indoor slide base.

11. The adjustable bracket of claim 10 , wherein said ratchet teeth further comprises a first set of ratchet teeth and a second set of ratchet teeth.

12. The adjustable bracket of claim 11 , wherein said first set of ratchet teeth are configured to couple with said first pawl and wherein said second set of ratchet teeth are configured to couple with said second pawl.

13. The adjustable bracket of claim 12 , wherein said ratchet release handle is coupled to said first pawl and said second pawl via said connecting rod.

14. The adjustable bracket of claim 13 , wherein said indoor portion is movable from said extended position to said retracted position by pushing said sliding base toward said base, but said indoor portion is movable from said retracted position to said extended position only by applying a force to said ratchet release handle opposing said spring bias force.

15. The adjustable bracket of claim 1 , wherein said outdoor portion further comprises complementary ratchet teeth and pawls configured to allow said outdoor portion to be movable from said extended position to said retracted position by pushing said outdoor portion toward said base, but configured to allow said outdoor portion to be movable from said retracted position to said extended position only by applying decoupling said pawls from said ratchet teeth.
