Mounting bracket assembly for appliance

1 . A mounting assembly for mounting an appliance to a wall comprising:

a first bracket having a wall-facing surface and an appliance-facing surface and at least one ledge protruding outwardly away from said wall-facing surface;

an appliance having a top surface, a bottom surface, a rear surface, side surfaces, and a front surface;

a second bracket coupled to said rear surface of said appliance, wherein said second bracket further comprises a cam having a cam axis and an outer camming surface with increasing radius therealong, said cam rotatably coupled to rotate about said cam axis from a cam home position through a range of intermediate cam positions to a final cam position; and

wherein said cam occupies said cam home position when said appliance is coupled to said first bracket by positioning said cam over top of said at least one ledge, and wherein said cam occupies said final cam position after said cam has been rotated by a user a predetermined amount.

2 . The mounting assembly of claim 1 , wherein said rear surface further comprises a recess therein.

3 . The mounting assembly of claim 2 , wherein at least a portion of said cam is positioned within the confines of said recess.

4 . The mounting assembly of claim 1 , wherein said cam is coupled to a cam shaft extension that projects through an opening in said appliance.

5 . The mounting assembly of claim 1 , wherein when said appliance is coupled to said first bracket and said cam is in said cam home position, a gap exists between said top surface of said appliance and a bottom surface of an obstacle.

6 . The mounting assembly of claim 5 , wherein as said cam is rotated from said cam home position to said final cam position, said gap distance decreases in size from said initial gap distance to a final gap distance.

7 . The mounting assembly of claim 1 , said second bracket further comprising a receiving opening therein to receive said at least one ledge.

8 . The mounting assembly of claim 7 , wherein said cam is rotatably coupled to said second bracket above said receiving opening.

9 . A method for installing an appliance on a wall beneath an obstacle, the appliance including an enclosure with a cooking cavity configured to receive food, wherein the enclosure includes at least a rear side and a top side, the method comprising:

installing a first bracket on a wall, wherein the first bracket has a ledge depending outwardly therefrom and includes a ledge support surface;

providing an appliance having a second bracket, wherein said second bracket includes a cam rotatably coupled thereto, wherein said cam further includes a camming surface having increasing radii therealong in a radial direction;

placing said appliance onto said first bracket by positioning said cam over said ledge;

allowing said appliance to move vertically downwardly until said cam rests on said ledge support surface;

rotating said cam to bring said increasing radii of said camming surface into contact with said ledge support surface; and

continuing to rotate said cam until a maximum radius of said camming surface is in contact with said ledge support surface.

10 . The method of claim 9 , further comprising installing said second bracket having said cam on said appliance.

11 . The mounting assembly of claim 1 wherein said second bracket includes at least one bracket receiving opening disposed therein, wherein said at least one bracket receiving opening has an opening top surface and said bracket receiving opening is alignable with said at least one ledge to receive said at least one ledge under said opening top surface when said second bracket occupies a first position relative to said first bracket; wherein said second bracket is moveable by a user to a second position relative to said first bracket to place said opening top surface in contact with said at least one ledge and wherein said cam occupies said cam home position when said second bracket occupies said first position relative to said first bracket.

12 . The mounting assembly of claim 11 , wherein said cam occupies said cam home position when said second bracket is in said second position relative to said first bracket.

13 . The mounting assembly of claim 1 , wherein said cam is rotatable by a user to a different cam position when a portion of said outer camming surface having a larger radius is rotated into contact with said at least one ledge.

14 . The mounting assembly of claim 1 , wherein a cam shaft extension having a tool engaging structure thereon is coupled to said cam.

15 . The mounting assembly of claim 14 , wherein said tool engaging structure receives a tool for imparting rotational movement to said cam to rotate said cam between said cam home position and said final cam position.

16 . The mounting assembly of claim 1 , wherein said second bracket is moveable linearly with respect to said first bracket in proportion to the increase in radius of the portion of the camming surface that contacts said at least one ledge.

17 . The mounting assembly of claim 11 , wherein when said second bracket is in said second position with respect to said first bracket, a gap having an initial gap distance exists between a top surface of the appliance and a bottom surface of an upper obstacle.

18 . The mounting assembly of claim 17 , wherein as said cam is rotated from said cam home position to said final cam position, said gap closes.

19 . The mounting assembly of claim 1 , further comprising a wedge screw mechanism.

20 . The mounting assembly of claim 19 , wherein said wedge screw mechanism further comprises a first wedge, a second wedge, and a bolt coupling said first wedge to said second wedge in slideable engagement therebetween.
