Abstract
Abstract A smoke shield assembly for an over-the-range oven includes a magnetically hinged deflecting shield movable between stored and in use positions. The assembly includes a metal base secured to a forwardly positioned bottom metal member of the over-the-range oven by four magnets. Two of the magnets securing the base to the oven also form a magnetic hinge that secures the deflecting shield to the base. The two other magnets securing the base to the oven further maintain the deflecting shield in the stored position. The deflecting shield is metal having a generally U-shaped pivot end magnetically secured to the base. The pivot end may have an unhemmed pivot edge or a hemmed pivot edge to ease pivoting between the stored and in use positions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
80 words
A smoke shield assembly attachable to a magnetically attractable member spaced above a cook top comprising: a base made of a magnetically attractable material; magnet means for securing said base to said member; and deflecting means for deflecting smoke from said cook top away from a user, said deflecting means having a pivot end made of a magnetically attractable material pivotally secured to said base by said magnet means for movement between a stored position and an in use position.
Claim 2
Dependent Claim
80 words
A smoke shield assembly attachable to a magnetically attractable member spaced above a cook top comprising: a base made of a magnetically attractable material; magnet means for securing said base to said member; and deflecting means for deflecting smoke from said cook top away from a user, said deflecting means having a pivot end made of a magnetically attractable material pivotally secured to said base by said magnet means for movement between a stored position and an in use position.
Claim 3
Dependent Claim
25 words
