Abstract
Abstract A metal door frame has trim molding applied to its flanges by the aid of separate clips. Each clip interfits an aperture in the flange and a notch at the flange edge. The aperture and the notch are punched in the flange so that the spacing thereof from the corner of the flange is constant whereby alignment of the clips is assured notwithstanding lack of critical dimensional control of the flange.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
131 words
In a door frame structure: (a) a frame part having a flange extending from a corner with the body of the flange adapted to lie flat along a wall surface adjoining a wall opening; said flange having a distal edge that deviates from parallelism with said corner; (b) said flange having a series of integrally formed longitudinally spaced discrete clip registers each located at the same constant predetermined dimensionally controlled distance from said corner; (c) a series of molding clips fitted and rigidly secured at said clip registers respectively; and (d) a trim molding member attached to said flange by said molding clips; (e) the distal edge of said flange having a series of preformed notches of variable depths interfitting corresponding ends of said clips to assist in accurate location thereof.
Claim 2
Dependent Claim
131 words
In a door frame structure: (a) a frame part having a flange extending from a corner with the body of the flange adapted to lie flat along a wall surface adjoining a wall opening; said flange having a distal edge that deviates from parallelism with said corner; (b) said flange having a series of integrally formed longitudinally spaced discrete clip registers each located at the same constant predetermined dimensionally controlled distance from said corner; (c) a series of molding clips fitted and rigidly secured at said clip registers respectively; and (d) a trim molding member attached to said flange by said molding clips; (e) the distal edge of said flange having a series of preformed notches of variable depths interfitting corresponding ends of said clips to assist in accurate location thereof.
Claim 3
Dependent Claim
103 words
In a door frame structure: (a) a frame part having a flange extending from a corner and adapted to lie along a wall surface adjoining a wall opening; (b) said flange having a longitudinal series of pairs of lanced openings; each pair of openings forming opposed tabs; (c) a corresponding series of clips, each clip extending between the tabs, each clip having on opposite sides means interfitted with the base portions of said tabs, said tabs being bent over the corresponding clip to locate said clips both longitudinally and transversely; and (d) a trim molding member attached to said flange by said clips.
Claim 4
Dependent Claim
103 words
In a door frame structure: (a) a frame part having a flange extending from a corner and adapted to lie along a wall surface adjoining a wall opening; (b) said flange having a longitudinal series of pairs of lanced openings; each pair of openings forming opposed tabs; (c) a corresponding series of clips, each clip extending between the tabs, each clip having on opposite sides means interfitted with the base portions of said tabs, said tabs being bent over the corresponding clip to locate said clips both longitudinally and transversely; and (d) a trim molding member attached to said flange by said clips.
Claim 5
Dependent Claim
36 words
The door frame structure as set forth in claim 2 in which each clip includes an outer projection and an inner projection and in which said molding member has legs dimensioned to snap fit said projections.
Claim 6
Dependent Claim
33 words
The door frame structure as set forth in claim 2 in which each clip includes an outer curl and an inner curl, said molding member having legs dimensioned to snap fit said curls.
Claim 7
Dependent Claim
103 words
In a door frame structure: (a) a frame part having a flange extending from a corner and adapted to lie along a wall surface adjoining a wall opening; (b) said flange having a longitudinal series of pairs of lanced openings; each pair of openings forming opposed tabs; (c) a corresponding series of clips, each clip extending between the tabs, each clip having recesses on opposite sides interfitted by the base portions of said tabs, said tabs being bent over the corresponding clip to locate said clips both longitudinally and transversely; and (d) a trim molding member attached to said flange by said clips.
Claim 8
Dependent Claim
103 words
In a door frame structure: (a) a frame part having a flange extending from a corner and adapted to lie along a wall surface adjoining a wall opening; (b) said flange having a longitudinal series of pairs of lanced openings; each pair of openings forming opposed tabs; (c) a corresponding series of clips, each clip extending between the tabs, each clip having recesses on opposite sides interfitted by the base portions of said tabs, said tabs being bent over the corresponding clip to locate said clips both longitudinally and transversely; and (d) a trim molding member attached to said flange by said clips.
Claim 9
Dependent Claim
36 words
The door frame structure as set forth in claim 5 in which each clip includes an outer projection and an inner projection, and in which said molding member has legs dimensioned to snap fit said projections.
Claim 10
Dependent Claim
29 words
The door frame structure as set forth in claim 6 in which said projections are in the form of curls, each clip being rigid relative to said molding member.
Claim 11
Dependent Claim
37 words
The door frame structure as set forth in claim 7 in which the distal edge of said flange has a series of notches interfitting corresponding outer curls of said clips to stabilize said clips against angular movement.
