Abstract
Abstract A door frame made up of two jamb sections and a head section connected together to fit into a rough door opening. The sections are each made up of an elongated, generally channel-shaped member having two spaced legs and an elongated, generally Z-shaped member having a flat surface disposed parallel to the legs of the channel. Surfaces of the Z-shaped member are supported in spaced, parallel relation to the surfaces of the channel member, providing spaces to receive wall material therebetween.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
168 words
A door frame comprising a head section and two jamb sections, said sections each comprising an elongated generally channel shaped member and a generally Z-shaped stiffener member defining generally flat front wall and substantially flat side walls extending generally perpendicular to one side of said front wall, the outer end portion of said side walls being bent inwardly at approximately 90° forming a channel, the inner ends of said channel being bent toward said front wall forming a first inner end and a second inner end generally parallel to each other, a generally Z-shaped spacer approximately equal length to said front wall, said spacer having a first leg and a second leg disposed generally parallel to each other and to said side walls of said channel, one of said ends of the said Z-shaped spacer being adapted to be secured to one of the side walls of said channel and means for securing one of said end walls to said one side wall with an element supported therebetween.
Claim 2
Dependent Claim
168 words
A door frame comprising a head section and two jamb sections, said sections each comprising an elongated generally channel shaped member and a generally Z-shaped stiffener member defining generally flat front wall and substantially flat side walls extending generally perpendicular to one side of said front wall, the outer end portion of said side walls being bent inwardly at approximately 90° forming a channel, the inner ends of said channel being bent toward said front wall forming a first inner end and a second inner end generally parallel to each other, a generally Z-shaped spacer approximately equal length to said front wall, said spacer having a first leg and a second leg disposed generally parallel to each other and to said side walls of said channel, one of said ends of the said Z-shaped spacer being adapted to be secured to one of the side walls of said channel and means for securing one of said end walls to said one side wall with an element supported therebetween.
Claim 3
Dependent Claim
50 words
