Abstract
Abstract A base trim system for partition corners comprises a base trim and a mounting bracket for the base trim. The base trim piece for the corner of intersecting walls has two upright wings angularly joined at a first edge of each, a recessed flange joined to the opposite edge of each wing, and a planar hook projecting upwardly from each such flange to lie in a plane between the vertical planes of the corresponding wings and flanges. The hook acts as a fastener for an abutting planar base trim piece. The mounting bracket has two planar upright wings, a recessed attachment flange connected to each wing, and an upwardly oriented planar hook extending above each attachment flange. The attachment flanges of this mounting bracket extend laterally beyond the lower flanges of the base trim.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
A base trim system for partition corners comprising a base trim and a mounting bracket for the base trim, said mounting bracket having two planar upright wings angularly joined at a first edge of each, a recessed attachment flange connected to the opposite edge of each wing and extending laterally away from the associated wing, an upwardly oriented planar hook extending above each attachment flange in a plane parallel to but between the vertical planes of the flange and the wing with which it is associated; said base trim having two planar upright wings angularly joined at a first edge of each and overlying the corresponding wings of the mounting bracket, a recessed lower flange connected to the opposite edge of each trim wing and fastened to the corresponding attachment flange of the mounting bracket in an overlying relationship; the attachment flanges of the mounting bracket extending laterally beyond the lower flanges of the base trim and being attached to the intersecting walls which form the partition corner.
Claim 2
Dependent Claim
168 words
A base trim system for partition corners comprising a base trim and a mounting bracket for the base trim, said mounting bracket having two planar upright wings angularly joined at a first edge of each, a recessed attachment flange connected to the opposite edge of each wing and extending laterally away from the associated wing, an upwardly oriented planar hook extending above each attachment flange in a plane parallel to but between the vertical planes of the flange and the wing with which it is associated; said base trim having two planar upright wings angularly joined at a first edge of each and overlying the corresponding wings of the mounting bracket, a recessed lower flange connected to the opposite edge of each trim wing and fastened to the corresponding attachment flange of the mounting bracket in an overlying relationship; the attachment flanges of the mounting bracket extending laterally beyond the lower flanges of the base trim and being attached to the intersecting walls which form the partition corner.
Claim 3
Dependent Claim
48 words
The system of claim 1 wherein the attachment flanges of the mounting bracket each have a tab and the lower flanges of the trim each have a slot through which such a tab passes, the tabs being bent toward the partition to fasten the trim to the bracket.
Claim 4
Dependent Claim
30 words
The system of claim 1 wherein the base trim has an upper flange connected to the opposite edge of each wing in the vertical plane of the corresponding lower flange.
Claim 5
Dependent Claim
24 words
The system of claim 1 wherein the attachment flanges of the mounting bracket each have a lip projecting outwardly from the lower margin thereof.
