Abstract
Abstract An awning rail for use in attaching an awning or similar flexible sheet material to a rigid structure comprising an extruded channel member, and an elastomeric member mounted in the channel which serves to trap a cord that is provided in the periphery of conventional awnings to hold the awnings securely, and under any desired amount of tension. The structure is easy to make, and the configuration is such that the awning cord member is easily inserted or removed from the structure.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
233 words
A fastening device for attaching awnings or similar sheets having an enlarged hem adjacent the edges thereof to a support structure, said device including an elongated member having a base, a first edge portion and a second edge portion spaced from the first edge portion; means to attach said device to a support structure; said first edge portion including a wall extending from the base to form a concave surface facing the second edge portion, said concave surface being of size to receive at least a portion of a hem of a sheet to be held; a flexible lock strip; said second edge portion defining a generally longitudinally extending slot facing said concave surface, said flexible lock strip having a first edge configured to correspond to and being mounted in said slot, said flexible lock strip extending obliquely to the base from said slot toward said wall forming said concave surface, and a second edge of said flexible lock strip being spaced from said wall a distance less than the thickness of a hem of a sheet to be held with the flexible lock strip in a normal rest position, said second edge of said flexible lock strip engaging a hem positioned in the concave surface to lock such a hem in said device, said flexible lock strip being depressable toward said base to permit releasing a hem positioned in the concave surface.
Claim 2
Dependent Claim
233 words
A fastening device for attaching awnings or similar sheets having an enlarged hem adjacent the edges thereof to a support structure, said device including an elongated member having a base, a first edge portion and a second edge portion spaced from the first edge portion; means to attach said device to a support structure; said first edge portion including a wall extending from the base to form a concave surface facing the second edge portion, said concave surface being of size to receive at least a portion of a hem of a sheet to be held; a flexible lock strip; said second edge portion defining a generally longitudinally extending slot facing said concave surface, said flexible lock strip having a first edge configured to correspond to and being mounted in said slot, said flexible lock strip extending obliquely to the base from said slot toward said wall forming said concave surface, and a second edge of said flexible lock strip being spaced from said wall a distance less than the thickness of a hem of a sheet to be held with the flexible lock strip in a normal rest position, said second edge of said flexible lock strip engaging a hem positioned in the concave surface to lock such a hem in said device, said flexible lock strip being depressable toward said base to permit releasing a hem positioned in the concave surface.
Claim 3
Dependent Claim
55 words
The combination as specified in claim 1 wherein said first edge portion wall comprises a wall member formed in a C-shape, said wall having an edge spaced from said base, said edge being rounded to permit a sheet held by said device to slide around said rounded edge when such a sheet is under tension.
Claim 4
Dependent Claim
118 words
The combination of claim 1 wherein said lock strip has a first surface facing said base and a second surface facing away from said base, said slot being partially defined by a support surface on said second edge portion of said elongated member which engages the first surface of said lock strip, said support surface terminating to permit a substantial portion of said lock strip extending toward said wall to be unsupported from movement toward said base, and wherein said elongated member has a wall fixed to the second edge portion and extending toward said first edge portion for a greater distance than said support surface, said last mentioned wall overlying the second surFace of said lock strip.
Claim 5
Dependent Claim
47 words
The combination as specified in claim 3 and a relief groove defined in said first surface of said lock strip and extending along the lock strip adjacent the support surface, said relief groove permitting the unsupported portion of said lock strip to be hinged toward said base.
Claim 6
Dependent Claim
36 words
The combination of claim 1 wherein said device is fastened to said support structure with fastening members extending through said base, said lock strip overlying said fastening members to shield said fastening members from external view.
