## Background
CROSS-REFERENCE TO RELATED APPLICATIONS
This is a utility patent application being filed in the United States as a non-provisional application for patent under Title 35 U.S.C. §100 et seq. and 37 C.F.R. §1.53(b) and, claiming the benefit of the prior filing date under Title 35, U.S.C. §119(e) of the United States provisional application for patent that was filed on Jul. 14, 2015, and assigned Ser. No. 62/192,252, which application is incorporated herein by reference in its entirety.


BACKGROUND
After installation, a door or panel vertically mounted on a frame may be moved out of a vertical orientation such that the door or panel will involuntarily move after being positioned. A former solution to this unwanted movement included removing the door or panel and adjusting, or re-shimming the frame to level the frame and thus restore the door or panel to vertical. After leveling, other cosmetic work, e.g., caulking and painting, may be needed to restore the frame and door/panel to an acceptable aesthetic level. Such procedures may risk damage to the door/panel and/or frame.
If the panel/door cannot be re-leveled and/or shimmed, a door or panel stop may be needed. Such a stop may be installed on a floor under the door or panel; or another type of hinge must be used.
SUMMARY
A barrel hinge clip may include a plate section configured to be mounted on a barrel hinge plate and an annulus section configured to receive a barrel hinge pin, wherein the plate and annulus sections are optionally reversibly attached to one another.
An article may include a first barrel hinge clip comprising a first plate section configured to engage a first barrel hinge plate and a first annulus section; a second barrel hinge clip comprising a second plate section configured to engage a second barrel hinge plate and a second annulus section wherein the first and second annulus sections are coaxially aligned; a threaded locking nut coaxially aligned with the first and second annulus sections; and an annular base plate and hollow screw coaxially aligned with the first and second annulus sections wherein the screw passes through the first and second annulus sections and is configured to engage the threaded locking nut.
A method to arrest panel movement of a panel rotatably mounted on a frame with a barrel hinge comprising: a) removing a barrel hinge pin from a barrel defined by a frame hinge plate mounted to the frame and a panel hinge plate mounted to the panel; b) mounting the article such that the first hinge clip engages the frame hinge plate and the second hinge clip engages the panel hinge plate; c) inserting the barrel hinge pin into the hollow screw and through the barrel; and d) rotating the threaded locking nut to compress the annuli sufficient to arrest panel movement.

The clip, annulus, and shank described supra may be formed of metal, a plastics, a composite, and the like. The clip, annulus, and shank may be manufactured by known methods to a person of ordinary skill in the art, including 3-D printing.
With respect to all figures, clips 100A-100D may be interchanged, as needed, with clips 202 and 204 depending on the configuration of the hinge, panel, and frame.
In an embodiment, the one or more surfaces, e.g., top surface TS or lower surface LS of the annuli 110 and/or 124 may be coated with a plastics, e.g., a nylon coating, or a fluorocarbon, e.g., a polytetrafluoroethylene polymer.
With reference to FIG. 2 and FIG. 3, in an embodiment, the clips, annuli, and shanks described supra may be assembled to make an article 200. Clip 202 with annulus 206 is aligned with annulus 208 of clip 204 along axis A. Washer 210 may be positioned between annuli 206 and 208 along axis A. Washer 210 comprises, at least, upper and/or lower surfaces of minimal static friction coefficient such that clips 204 and 202 may turn clockwise (C), and anti-clockwise (AC) relative to each other about axis A, when in use.
In an embodiment, washers 210 and/or 212 may be manufactured of a material with a low coefficient of static friction. Non-limiting examples include a polytetrafluoroethylene polymer, a polyimide polymer, e.g., a Kapton® polymer, an aliphatic or aromatic polymer such as nylon, e.g., a PA 6, PA 66, PA 6/66 or PA 66/610 nylon.
In an embodiment, the washers 210 and/or 212 may be compressible and or may be resiliently biased along the direction of axis A or they may be bendable out of the plane of the washers.
In an embodiment the coating on annuli 206 and/or 208 and/or washers 210, 212, may comprise a material with a static coefficient of friction (μs) of about 0.02 to about 0.25; or from about 0.04 to about 0.25; or from about 0.05 to about 0.2; or from about 0.1 to about 0.25; or from about 0.1 to about 0.2.
In an embodiment annuli 206 and/or 208, and/or washers 210, 212, may comprise a material with a static coefficient of friction (μs) of about 0.02 to about 0.25; or from about 0.04 to about 0.25; or from about 0.05 to about 0.2; or from about 0.1 to about 0.25; or from about 0.1 to about 0.2.
In an embodiment, washer 212 may be positioned between the upper surface of annulus 208 and threaded nut 214 such that clip 204 may turn relative to nut 214. Nut 214 engages threaded, hollow screw 216 and may be tightened such that base plate 218 meets the underside of annulus 206.
In an embodiment, the base plate 218 may be fixed to annulus 206 by any method known to a person of ordinary skill in the art, e.g., welding, gluing, tacking, bonding, and the like. In this way, hollow screw 216 and base plate 216 do not turn when nut 214 is tightened, thus compressing 206, 208, 210 and/or 212.
In an embodiment, a threadlocking adhesive may be used to maintain a selected position of the tightened nut. For example, a cyanoacrylate, an epoxy, or other resin may be used. Such threadlocking adhesives may be known under the registered trademark LOCTITE® threadlocker.
In an alternative embodiment, with reference to FIG. 2 and FIG. 2A, base plate 218A and hollow post/threaded screw 216 engage coiled spring 217 such that when assembled with this alternative embodiment, article 200 has increased force operating against and thus compressing 206, 208, 210 and/or 212.
In an alternative embodiment, with reference to FIG. 2 and FIG. 2A, base plate 218A and hollow post/threaded screw 216 engage lock washer 219 such that when assembled with this alternative embodiment, article 200 has increased force operating against and thus compressing 206, 208, 210 and/or 212.
In an alternative embodiment, the screw, baseplate and nut combination may be substituted with a fastener or fastening module with a central hole configured to receive a barrel hinge pin. Such modules and equivalents thereof are known or are apparent to those of skill in the art.
With reference to FIG. 3A, such a fastener may include a rivet system wherein the bottom, or originally flared part of the rivet, is equivalent to base plate 218, and the rivet shaft is equivalent to hollow screw 216. After assembly, the top portion of the rivet shaft is flared and thus compresses 206, 208, 210, and 212.
In another embodiment, with respect to FIGS. 2, 216 and 218 may be manufactured as a single piece. In another embodiment, with respect to FIG. 2, FIG. 2A, FIG. 3, and FIG. 3A, the combination of 214, 216 and 218 may manufactured as a single piece.
With reference to FIG. 2, FIG. 3, and FIG. 4, article 200 is aligned along axis A such that clip 202 engages the upper edge of hinge plate 220 and clip 204 engages the upper edge of hinge plate 222. In this manner interlocking hinge plates knuckles 220A, 222A, 220B, 222B, and 220C are aligned along axis A. Barrel pin 224 is aligned along axis A and pressed through hollow screw 216 until top plate 226 meets the top of screw 226.
In an embodiment, and with respect to FIG. 5, hinge plate 220 is secured to a frame 228 and hinge plate 222 is secured to swinging panel 230, e.g., a door, a cabinet door, and the like, by one or more screws 232. In an embodiment, the width Z and/or Z′ of clips 202 and/or 204, respectively, is less than or equal to distance Y and/or Y′, respectively, a length from a hinge knuckle 220C to frame 228, and/or a distance from hinge knuckle 220C to panel 230. Y and Y′ are optionally the same distances; and Z and Z′ are optionally the same distances.
Should distances Y and/or Y′ be less than Z and/or Z′, the clips 202 and/or 204 may be fitted on hinge plates 220 and 222 before hinge plates 220 and/or 222 are secured with screws 232. Thus a portion of clip 204 may be secured between plate 220 and frame 228. Similarly, a portion of clip 202 may be secured between plate 222 and panel 230.
A method of arresting a door movement may be effected by mounting article 200 on base plates 220 and 222 and tightening nut 214 against screw 216 and base plate 218. The nut may be tightened until 206, 208, 210 and 212 are compressed such that panel 230, when rotated to certain position relative to frame 228, stays in position.
