Abstract
Abstract A split-tubular track structure to receive carriage means for suspending sliding doors from a wall of a building and brackets for mounting the track on a building wall above a door opening. Preferably the brackets have fastening flanges parts of which overlie a horizontal surface of the building wall so as to be mounted by nails driven through the horizontal surface, track flanges on the brackets have depending headed studs which slidably engage a line of keyhole slots in the upper part of the track for quick mounting of the track on the brackets, and means are provided for preventing the track from moving relative to the brackets. For outdoor use the bracket track flanges extend downwardly and outwardly from the track, and a continuous shield has its upper edge portion secured to the building wall and its lower edge portion folded around the outer ends of the track flanges. Firm contact between an intermediate portion of the shield and the tops of the track flanges bows the shield to damp vibration and to give the shield a smooth surface appearance.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
308 words
A track structure for suspending sliding doors from a wall of a building, said structure comprising, in combination: a tubular track having a sidewall with a continuous longitudinal split in its lowermost portion so that door suspending carriage means may be carried in the track and have depending door hanger members extending through the split to suspend a door below the track, said track having a line of spaced keyhole slots remote from said split, each of said keyhole slots having a long dimension with a small diameter portion, and a large diameter portion, and all of said small diameter portions being aligned with one another along the length of the track; a plurality of hanger brackets each of which includes a fastening flange fixed to a wall of a building, and a track flange; a stud mounted on and projecting from each track flange, each said stud having a shank permanently and rigidly affixed to the track flange, the diameter of each shank being less than that of the small diameter portion of a keyhold slot, and a head at the outer end of the shank the diameter of which is greater than that of the small diameter portion and less than that of the large diameter portion of a slot, said track having its keyhole slots engaged with the studs so that each stud head is within the track and each shank impales the small diameter portion of a slot, and said track sidewall making a sliding fit between the track flange and the stud head; a small number, not less than one, of said keyhole slots having its large diameter and small diameter portions reversely oriented with reference to said portions of the remainder of said line of keyhole slots, said reverse orientation providing means for preventing movement of the track relative to the brackets.

A track structure for suspending sliding doors from a wall of a building, said structure comprising, in combination: a tubular track having a sidewall with a continuous longitudinal split in its lowermost portion so that door suspending carriage means may be carried in the track and have depending door hanger members extending through the split to suspend a door below the track, said track having a line of spaced keyhole slots remote from said split, each of said keyhole slots having a long dimension with a small diameter portion, and a large diameter portion, and all of said small diameter portions being aligned with one another along the length of the track; a plurality of hanger brackets each of which includes a fastening flange fixed to a wall of a building, and a track flange; a stud mounted on and projecting from each track flange, each said stud having a shank permanently and rigidly affixed to the track flange, the diameter of each shank being less than that of the small diameter portion of a keyhold slot, and a head at the outer end of the shank the diameter of which is greater than that of the small diameter portion and less than that of the large diameter portion of a slot, said track having its keyhole slots engaged with the studs so that each stud head is within the track and each shank impales the small diameter portion of a slot, and said track sidewall making a sliding fit between the track flange and the stud head; a small number, not less than one, of said keyhole slots having its large diameter and small diameter portions reversely oriented with reference to said portions of the remainder of said line of keyhole slots, said reverse orientation providing means for preventing movement of the track relative to the brackets.
Claim 3
Dependent Claim
36 words
The combination of claim 1 in which the keyhole slots are oriented with their long dimensions extending longitudinally of the track, and in which a reversely oriented slot is immediately adjacent one end of the track.
Claim 4
Dependent Claim
41 words
The combination of claim 1 in which the keyhole slots are oriented with their long dimensions extending circumferentially of the track, and in which tHere are two reversely oriented slots on opposite sides of the transverse median plane of the track.
Claim 5
Dependent Claim
31 words
The combination of claim 1 in which the centers of the aligned small diameter portions of the keyhole slots are 180* from the center line of the split in the track.
Claim 6
Dependent Claim
35 words
The combination of claim 1 in which the fastening flanges of the brackets include upright portions, and fastening means impale said upright flange portions and extend into the building wall through a vertical wall surface.
Claim 7
Dependent Claim
59 words
The combination of claim 1 in which the fastening flanges of the brackets include upright portions abutting a vertical surface of a building wall and terminal portions perpendicular to said upright portions which overlie a horizontal surface of the building wall, and in which fastening means impale said terminal portions and extend into said wall through said horizontal surface.
Claim 8
Dependent Claim
105 words
The combination of claim 1 in which the track flanges of the brackets have inner ends which are positioned above the track between the building wall and a vertical plane along the center of the track split and outer ends which are positioned substantially below the lowermost portion of the track and farther from the building wall than any part of the track, and in which a separate continuous shield of thin gauge sheet material has a lower end portion secured to the outer ends of the bracket track flanges and a secured upper end portion abutting the building wall above the bracket mounting flanges.
Claim 9
Dependent Claim
255 words
A track structure for suspending sliding doors from a wall of a building, said structure comprising, in combination: a tubular track having a sidewall with a continuous longitudinal split in its lowermost portion so that door suspending carriage means may be carried in the track and have depending door hanger members extending through the split to suspend a door below the track; a plurality of hanger brackets each of which includes a fastening flange fixed to a wall of a building and a track flange that has an inner end which is positioned above the track between the building wall and a vertical plane along the center of the track split, and each said track flange having an outer end which is positioned substantially below the lowermost portion of the track and farther from the building wall than any part of said track; fastening means impaling the upper portion of the track and also impaling each said bracket track flange to rigidly secure the track to the brackets; separate shield means of thin gauge sheet material which is at least as long as the track and overlies the brackets and track, said shield means having a lower end portion folded around the outer ends of the bracket track flanges, having an intermediate portion which bears upon a part of the track structure to damp vibration of the shield, and having an upper end portion abutting the building wall above the brackets; and means securing the upper end portion of the shield to the building wall.
