Abstract

Abstract A microwave oven door aligning assembly is provided and includes a centering prong rigidly mounted on the door of the oven and projecting beyond the inside surface of the door. A clip is mounted to the oven behind the front face of the oven cavity and the clip has an opening in alignment with an opening in the front face. A centering prong receiving receptacle having a rigid square body portion is removably inserted into the clip opening and secured to the clip. The receptacle has a square opening to receive the centering prong which opening is offset from the center of the receptacle such that two opposite sides of the opening are equal distance from the center and the other two opposite sides of the opening are of unequal distance from the center. With this arrangement the receptacle may be rotatably installed to assure proper parallel alignment of the door relative to the top and bottom cabinet walls by cooperation between the centering prong and the receptacle.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 227 words
A microwave oven having a cabinet with top, bottom, rear and side walls defining an oven cavity with an opening in the front face thereof, a door movably mounted to said cabinet by hinges for selectively closing said opening, electrically operable microwave energy generating means for supplying microwave energy to said cavity, and an electrically operable circuit including switch means for providing electric power from an external source to said electrically operable microwave energy generating means, and a door aligning assembly for properly maintaining the door in parallel alignment relative to the top and bottom cabinet walls, the improvement comprising: a centering prong rigidly mounted on the door and projecting beyond the inside surface of the door, an opening in the front face remote from the door hinges, a clip mounted to the oven behind the front face, said clip having an opening in alignment with the front face opening, a centering prong receiving receptacle having a rigid square body portion removably inserted in the clip opening and means to secure the receptacle to the clip, said receptacle having a square opening to receive the centering prong which opening is offset from the center of the receptacle such that two opposite sides of the opening are equal distance from the center and the other two opposite sides of the opening are of unequal distance from the center.
Claim 2
Dependent Claim 227 words
A microwave oven having a cabinet with top, bottom, rear and side walls defining an oven cavity with an opening in the front face thereof, a door movably mounted to said cabinet by hinges for selectively closing said opening, electrically operable microwave energy generating means for supplying microwave energy to said cavity, and an electrically operable circuit including switch means for providing electric power from an external source to said electrically operable microwave energy generating means, and a door aligning assembly for properly maintaining the door in parallel alignment relative to the top and bottom cabinet walls, the improvement comprising: a centering prong rigidly mounted on the door and projecting beyond the inside surface of the door, an opening in the front face remote from the door hinges, a clip mounted to the oven behind the front face, said clip having an opening in alignment with the front face opening, a centering prong receiving receptacle having a rigid square body portion removably inserted in the clip opening and means to secure the receptacle to the clip, said receptacle having a square opening to receive the centering prong which opening is offset from the center of the receptacle such that two opposite sides of the opening are equal distance from the center and the other two opposite sides of the opening are of unequal distance from the center.
Claim 3
Dependent Claim 44 words
The microwave oven of claim 1 wherein the receptacle opening goes through the receptacle and a switch with an actuating arm is located behind the opening such that the centering prong actuates the switch upon door closing and deactuates the switch upon door opening.
Claim 4
Dependent Claim 32 words
The microwave oven of claim 1 wherein the centering prong receiving receptacle has a peripheral flange portion at one end thereof and having a dimension greater than the opening in the clip.
Claim 5
Dependent Claim 75 words
The microwave oven of claim 3 wherein the clip opening is a vertical elongated rectangle having a first portion and a second portion and the receptacle body has projecting ears spaced from the peripheral flange and the first portion of the clip opening has cutouts for receiving the ears for positioning the receptacle body therein and the receptacle is movable to the second portion of the clip opening to secure the receptacle to the clip.
Claim 6
Dependent Claim 52 words
The microwave oven of claim 4 wherein the means to secure the receptacle to the clip is a friction fit between the receptacle and the clip provided by the clip having a depending lip along the periphery of the second portion of the clip opening to engage the ears of the receptacle.
