Abstract
Abstract A sliding door installation in a doorway. Framed door panels are guided over threshold trackways and suspended from roller wheels in trackways at the top of the doorway. Corner brackets interconnect rails and stiles framing the door panels. Identical brackets interchangeably utilizable to carry roller wheels or floating guides interconnect the rails and stiles at the corners of the door panels. The brackets include three spurred lugs for securing the brackets to the rails and stiles. The rails and stiles are designed to be interconnected by the brackets to form a sturdy frame around the door panel edges.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
159 words
A rail for framing an edge of a panel, the rail comprising: an elongated frame member having front, intermediate and rear walls forming an elongated channel for receiving the edge of a panel and also having a holding flange integral with said rear wall that extends toward said intermediate wall; said rear wall being angled relative to said front wall so that the distance between said rear and front walls decreases with increasing distance from said intermediate wall; said holding flange diverging away from rear wall with decreasing distance of said holding flange from said intermediate wall; said rear wall having a respective alignment slot near each end thereof being located a predetermined distance from the adjacent end of said rear wall; and said frame member including an integral tab portion adjacent to said slot and extending inward within said channel adjacent to said intermediate wall restricting the width of said channel in the region of said intermediate wall.
Claim 2
Dependent Claim
159 words
A rail for framing an edge of a panel, the rail comprising: an elongated frame member having front, intermediate and rear walls forming an elongated channel for receiving the edge of a panel and also having a holding flange integral with said rear wall that extends toward said intermediate wall; said rear wall being angled relative to said front wall so that the distance between said rear and front walls decreases with increasing distance from said intermediate wall; said holding flange diverging away from rear wall with decreasing distance of said holding flange from said intermediate wall; said rear wall having a respective alignment slot near each end thereof being located a predetermined distance from the adjacent end of said rear wall; and said frame member including an integral tab portion adjacent to said slot and extending inward within said channel adjacent to said intermediate wall restricting the width of said channel in the region of said intermediate wall.
Claim 3
Dependent Claim
82 words
The rail set forth in claim 1 wherein said front wall is folded double with the longitudinal edge of said front wall being disposed within said channel; said front wall being folded to form a reentrant portion with the end of said reentrant portion being inside of said channel and located in the region of the edge of said holding flange whereby a panel held within said rail includes a portion held between embracing edges of said rail and said reentrant portion.
Claim 4
Dependent Claim
23 words
The combination in accordance with claim 1 wherein said tab portion includes an edge exposed to said channel for receiving a panel edge.
Claim 5
Dependent Claim
152 words
A stile for framing an edge of a panel, said stile comprising: an elongated frame member having front, intermediate and rear walls defining an elongated channel therebetween an additional wall integral with said rear wall projecting toward said front wall for use as a holding flange; said additional wall being bent between said rear wall and its longitudinal holding edge to define a longitudinal portion of said additional wall that angles toward said front and intermediate walls; said front wall including an outward extending reentrant portion having a return portion including an edge adjacent to said elongated channel whereby a panel positioned within the channel of said stile includes a region embraced by the edges of said longitudinal holding Edge and said adjacent edge of said return portion; wherein said return portion of said outward extending reentrant portion includes a longitudinally extending recess adjacent to the edge portion of said return portion.
Claim 6
Dependent Claim
152 words
A stile for framing an edge of a panel, said stile comprising: an elongated frame member having front, intermediate and rear walls defining an elongated channel therebetween an additional wall integral with said rear wall projecting toward said front wall for use as a holding flange; said additional wall being bent between said rear wall and its longitudinal holding edge to define a longitudinal portion of said additional wall that angles toward said front and intermediate walls; said front wall including an outward extending reentrant portion having a return portion including an edge adjacent to said elongated channel whereby a panel positioned within the channel of said stile includes a region embraced by the edges of said longitudinal holding Edge and said adjacent edge of said return portion; wherein said return portion of said outward extending reentrant portion includes a longitudinally extending recess adjacent to the edge portion of said return portion.
Claim 7
Dependent Claim
52 words
The combination in accordance with claim 4 including panel means extending into the channel defined by said stile; a rail including a channel portion; the channel portion to said rail embracing an adjacent edge of said panel; the end of said rail terminating in the said longitudinally extending recess of said stile.
Claim 8
Dependent Claim
152 words
A rail for framing an edge of a panel, the rail comprising: an elongated frame member having front, intermediate and rear walls forming an elongated channel for receiving the edge of a panel and also having a holding flange integral with said rear wall that extends toward said intermediate wall; said rear wall being angled relative to said front wall so that the distance between said rear and front walls decreases with increasing distance from said intermediate wall; said holding flange diverging away from rear wall with decreasing distance of said holding flange from said intermediate wall; said front wall being folded to form a reentrant portion with the end of said reentrant portion being inside of said channel and located in the region of the edge of said holding flange whereby a panel held within said rail includes a portion held between embracing edges of said rail and said reentrant portion.
Claim 9
Dependent Claim
