Abstract
Abstract A fastener is disclosed for attaching a channel shaped fastening strip to a door frame or the like. The fastener comprises a pair of oppositely facing loops which are insertable into the channel of the facing strip and, in doing so, the loops frictionally engage the sides of the facing strip and secures the facing strip to the frame. At least one and preferably two tangs formed on the end of the fastener extend through it and engage the sides of an opening in the frame to detachably secure the fastener to the frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
224 words
A fastener for attaching a facing strip to a door frame or the like, said facing strip comprising an elongated base wall and a side wall extending substantially perpendicularly outwardly from each longitudinal edge of the base wall, said base wall and side walls together forming a channel, said fastener comprising: a pair of oppositely facing loops, said loops spaced from each other by a distance substantially the same as the distance between said facing strip side walls so that, upon insertion of said fastener into said channel, said loops frictionally engage the facing strip side walls, and means integrally formed with said fastener for detachably securing said fastener to the frame without deformation of said frame, wherein said frame includes a thin walled panel having an opening, said fastener comprising a central portion extending between said loops and abutting against one side of said thin walled panel and wherein said securing means comprises an attachment portion of said fastener extending through said opening, and wherein said fastener comprises an attachment portion attached at one end to and extending outwardly from one loop, said attachment portion flatly abutting against the other side of said thin walled panel, and wherein said attachment portion comprises a tang formed on its other end, said thin walled panel being sandwiched in between said central and said attachment portions.
Claim 2
Dependent Claim
224 words
A fastener for attaching a facing strip to a door frame or the like, said facing strip comprising an elongated base wall and a side wall extending substantially perpendicularly outwardly from each longitudinal edge of the base wall, said base wall and side walls together forming a channel, said fastener comprising: a pair of oppositely facing loops, said loops spaced from each other by a distance substantially the same as the distance between said facing strip side walls so that, upon insertion of said fastener into said channel, said loops frictionally engage the facing strip side walls, and means integrally formed with said fastener for detachably securing said fastener to the frame without deformation of said frame, wherein said frame includes a thin walled panel having an opening, said fastener comprising a central portion extending between said loops and abutting against one side of said thin walled panel and wherein said securing means comprises an attachment portion of said fastener extending through said opening, and wherein said fastener comprises an attachment portion attached at one end to and extending outwardly from one loop, said attachment portion flatly abutting against the other side of said thin walled panel, and wherein said attachment portion comprises a tang formed on its other end, said thin walled panel being sandwiched in between said central and said attachment portions.
Claim 3
Dependent Claim
34 words
The invention as defined in claim 1 and comprising a second tang secured to and extending outwardly from the other loop, said second tang extending through and frictionally engaging one side of said opening.
Claim 4
Dependent Claim
17 words
The invention as defined in claim 2 wherein said fastener comprises a one-piece band of resilient material.
Claim 5
Dependent Claim
14 words
The invention as defined in claim 3 wherein said resilient material comprises spring steel.
Claim 6
Dependent Claim
39 words
The invention as defined in claim 4 wherein said thin walled panel includes an edge and wherein at least a portion of said one loop is positioned over said edge whereby said one loop is deflectible over said edge.
Claim 7
Dependent Claim
224 words
A building construction for forming an opening in a wall partition comprising: a door frame, a fastener, said fastener having means for engaging a facing strip of the type having an elongated base wall and a side wall extending substantially perpendicularly outwardly from each longitudinal edge of the base wall, said base wall and side walls together forming a channel, and means integrally formed with said fastener for detachably securing said fastener to said door frame, wherein said fastener comprises a pair of oppositely facing loops, said loops spaced from each other by a distance substantially the same as the distance between said facing strip side walls so that, upon insertion of said fastener into said channel, said loops frictionally engage the facing strip side walls, and means integrally formed with said fastener for detachably securing said fastener to the frame, wherein said frame includes a thin walled panel having an opening, said fastener comprising a central portion extending between said loops and abutting against one side of said thin walled panel and wherein said securing means comprises an attachment portion of said fastener extending through said opening, wherein said frame includes a notch, said notch being longitudinally aligned with said opening, and wherein a portion of said fastener is positioned in said notch to prevent lateral movement between said fastener and said frame.
Claim 8
Dependent Claim
224 words
A building construction for forming an opening in a wall partition comprising: a door frame, a fastener, said fastener having means for engaging a facing strip of the type having an elongated base wall and a side wall extending substantially perpendicularly outwardly from each longitudinal edge of the base wall, said base wall and side walls together forming a channel, and means integrally formed with said fastener for detachably securing said fastener to said door frame, wherein said fastener comprises a pair of oppositely facing loops, said loops spaced from each other by a distance substantially the same as the distance between said facing strip side walls so that, upon insertion of said fastener into said channel, said loops frictionally engage the facing strip side walls, and means integrally formed with said fastener for detachably securing said fastener to the frame, wherein said frame includes a thin walled panel having an opening, said fastener comprising a central portion extending between said loops and abutting against one side of said thin walled panel and wherein said securing means comprises an attachment portion of said fastener extending through said opening, wherein said frame includes a notch, said notch being longitudinally aligned with said opening, and wherein a portion of said fastener is positioned in said notch to prevent lateral movement between said fastener and said frame.
