FIELD OF THE INVENTION
The field of the invention is door hardware.
BACKGROUND OF THE INVENTION
With the recent trend toward rustic elegance and the necessity for designs that bring both an esthetic value and a functional solution. Sliding-style doors, commonly referred to as “barn doors” have become a major component for DIY and contractor installation. These doors minimize space constraints caused by swinging doors in small places such as bathrooms and laundry rooms, but also bring a decorative flare to any room.
Given the demand for these sliding doors, a combination of both esthetic value and safety requirements are a must. Installation of these doors then becomes a challenge to combine the two.
Traditional sliding doors have a mounting system that while offering an attractive look, often lacks in safety and ease of installation. Conventional mounting hardware consists of basic components, a track, mounting spacers, lag bolts, door hangers/rollers, floor door guides, and door stops. Most off-the-shelf hardware comes with a pre-drilled track at 16 inch centers for placement on wall studs. This is fine when studs are where they are supposed to be, but sometimes the pre-drilled mounting holes in the metal rail may not align horizontally with the location of support studs or the pre-drilled pilot holes in the support stud. While it may be possible to drill holes in a metal rail to line up with pre-drilled pilot holes in the wall studs, drilling holes in metal requires additional tools, accuracy, and strength, significantly extends the time to install a door, and leaves unsightly unused holes in the track. Additionally, the lag bolt system creates a safety issue, as the off-the-shelf hardware comes with three-inch lag bolts that must penetrate the track, a 1-inch thick spacer, and sheetrock ¾ inch thick. This does not leave much bolt length to securely and safely hold the weight of the track and suspended door. Plus, the combined weight of the rail and the door imposes a vertical load on the head end of the bolt which can cause the spacer and lag bolt to bend and crush into the sheet rock or other wall material below the bolt.
In addition, the doors in some hanging door systems may come off the tracks, for example under heavy winds or powerful lateral door forces.
Finally, sometimes it may be desirable to adjust the distance between the top edge of the hanging door and the rail from which it is suspended. It may be desirable, for example, to raise the bottom edge of the door above the ground or floor. Or, when two or more doors are hung together, sometimes the top edges of the doors may not be aligned horizontally in a pleasing manner.
SUMMARY OF THE INVENTION

The hanger track supported by one or more mounting brackets comprising a mounting surface and a clamp defining a gap adapted for receiving the hanging track. Alternative embodiments are also disclosed wherein the track is L-shaped, the rolling hanger comprises a stop arm, and the rolling hanger is vertically adjustable.

Rail 1140 is mounted securely in mounting bracket 1120 with mounting part 1142 of rail 1140 inserted into slot 1125 between support arm 1124 and clamp arm 1134 and secured with rail bolt 1150 extending through clamp arm 1134. Hanger 1160 includes wheel 1170 which is mounted on and rail part 1140. Wheel 1170 includes groove 1173. In an embodiment the low point of groove 1173 aligns with the center 1190 of wheel 1170. Hanger 1160 includes stop arm 1164 which extends horizontally so that stop arm tip end 1165 extends beyond the center of wheel 1170 and groove 1173 but not beyond the inner edge 1178 of wheel 1170. Stop part 1164 is disposed under mounting part 1142 of rail 1140 so that mounting part 1142 does not impede travel of hanger 1160 along rail 1140. Tip end 1139 of support arm 1124 preferably does not extend horizontally beyond the inner edge 1178 of wheel 1170. Hanger 1160 is fastened to hanging door 1180 with fasteners 1162.
In an embodiment, stop arm 1164 is a safety feature that prevents the hanging door 1180 from falling off the track. If the vertical distance between hanger end 1167 and stop arm tip end 1165 is less than the depth of groove 1173, and preferably at least ⅛″ less than the depth of groove 1173, it is practically impossible for hanger 1160 to slip off of track 1140. Also, the wall 1110 preferably blocks hanger 1160 from being turned inward so as to fall off rail 1140.
FIGS. 12A and 12B depict an embodiment of an adjustable hanger 1260. Adjustable hanger 1260 comprises an upper hanger 1210 and lower hanger 1220, each constructed, in an embodiment, of flat bar steel. Upper hanger 1210 comprises wheel 1270 for rolling on the door hanging track, and lower hanger 1220 can be fastened to a hanging door via fasteners inserted through openings (not shown) in lower hanger 1220. Affixed to upper hanger 1210 is upper bolt mount 1230 comprising upper bolt arm 1234 and support 1232. Upper hanger 1210 in an embodiment includes a stop arm (not shown) and upper bolt mount 1230 is preferably affixed to upper hanger 1210 below the stop arm. In an embodiment, support 1232 is affixed to upper hanger 1210 by welded joint 1236. Affixed to lower hanger 1220 is lower bolt mount 1240 comprising lower bolt arm 1244 and support 1242. In an embodiment, support 1242 is affixed to lower hanger 1220 by welded joint 1246. Lower bolt arm 1244 includes an opening 1248 which can be aligned with a corresponding opening (not shown) in upper bolt arm 1234. Bolt 1250 extends vertically upward through opening 1248 and through threaded nut 1256, below upper bolt arm 1234, through an opening (not shown) in upper bolt arm 1234, and through threaded nut 1252, above upper bolt arm 1234. In an embodiment, bolt head 1254 of bolt 1250 may be affixed to lower surface 1245 of lower bolt arm 1244 by a welded joint (not shown) or one of nuts 1252 or 1256 may be affixed to upper bolt arm 1234 by a welded joint (not shown). In an embodiment, upper and lower bolt mounts 1230 and 1240, bolt 1250, and nuts 1256 and 1252 provide the sole means of joining together upper hanger 1210 and lower hanger 1220, which otherwise are not attached to each other. The vertical distance from wheel 1270 to lower hanger 1220 can be vertically adjusted by vertically adjusting the location of threaded nut 1252 on bolt 1250, and thus the height of the door suspended from lower hanger 1220 can be adjusted vertically in relation to the rail from which it is suspended.
In practice, sometimes it is desirable to adjust the height of one or more sides of a hanging door. For example, when hanging two or more doors, sometimes the top or side edges of the doors may not be aligned as desired. This problem can be solved by using one or more adjustable hangers 1260 to hang the doors and vertically adjusting the height of one or more sides of the door as needed to achieve the desired alignment or distance between the top of the door and the rail from which it is suspended.
The embodiments of a door hanging apparatus and system described herein overcome multiple problems encountered with exposed rail hanging door systems. The mounting brackets can be quickly mounted to wall studs at any spacing and securely hold the hanging door tracks without having to drill holes in the metal. Because the lag bolts that secure the mounting brackets to the wall are not extended, there is no risk of the bolts and spacers bending under the weight of the rail and door and damaging the wall. The unique integrated relationship between the wall mount and the door hanger makes the door hanger more safe. The hanger can travel freely along the track, but has critical spatial designs that make unintentional or accidental removal of the hanger from the track impossible. In short, the embodiments of a hanging door mounting system described herein simplify installation, incorporate safety features that minimize risk/possible injury, and provide an esthetic look that complements any home or commercial application.
Although embodiments of the present invention have been described in detail, it will be apparent to those skilled in the art that many embodiments taking a variety of specific forms and reflecting changes, substitutions and alterations can be made without departing from the spirit and scope of the inventions disclosed herein. The described embodiments illustrate the scope of the claims but do not restrict the scope of the claims.
