Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 143 words
Apparatus for sealing a door against leakage comprising: (a) a first thin metal strip extending around the periphery of the door on the face surface, (b) a first sealing strip mounted around the frame, including a base portion attached to the frame, a resilient collapsible portion extending from the base portion, and a magnetic portion extending from the collapsible portion, (c) a second metal strip mounted on the threshold including an inclined surface that faces in the direction of the opening of the door, and (d) a second sealing strip having a base portion attached to the face of the door adjacent the bottom edge, a resilient collapsible portion extending from the base portion, and a magnetic portion extending from the collapsible portion, said magnetic portion having a contact surface that is generally parallel to the inclined surface of the second metal strip.
Claim 2
Dependent Claim 143 words
Apparatus for sealing a door against leakage comprising: (a) a first thin metal strip extending around the periphery of the door on the face surface, (b) a first sealing strip mounted around the frame, including a base portion attached to the frame, a resilient collapsible portion extending from the base portion, and a magnetic portion extending from the collapsible portion, (c) a second metal strip mounted on the threshold including an inclined surface that faces in the direction of the opening of the door, and (d) a second sealing strip having a base portion attached to the face of the door adjacent the bottom edge, a resilient collapsible portion extending from the base portion, and a magnetic portion extending from the collapsible portion, said magnetic portion having a contact surface that is generally parallel to the inclined surface of the second metal strip.
Claim 3
Dependent Claim 72 words
Apparatus as recited in claim 1, wherein the base portion of the second sealing strip is a hollow extrusion that has a broad surface for attachment to the vertical face of the door and a wall that extends at an acute angle thereto to hold the collapsible portion and the magnetic portion at the appropriate angle to contact the said inclined surface of the second metal strip as the door is closed.
Claim 4
Dependent Claim 43 words
Apparatus as recited in claim 1, wherein each of the sealing strips consists of an integral extrusion of a polymer in which the collapsible portion is formed as a hollow bellows, and wherein a permanent magnetic bar is molded in the magnetic portion.
Claim 5
Dependent Claim 41 words
Apparatus as recited in claim 1, wherein the base portion of each sealing strip consists of a hollow extrusion of a polymer having at least one flat outer surface for broad engagement with and fastening to the surface of the frame.
