## Background
BACKGROUND
Many devices exist for hanging ceiling panels in an aircraft, vehicle, or other structure. Some of these devices utilize complex, multiple bar linkage assemblies. However, this may lead to an increased cost of manufacturing, may make installation more difficult, may reduce load capacity, may be less durable, may have an abundance of moving parts, and/or may have other problems. Other devices and/or methods may experience different types of problems.
A device, and method of use, is needed to decrease one or more problems associated with one or more of the existing devices and/or methods for hanging ceiling panels.

DETAILED DESCRIPTION
The following detailed description is of the best currently contemplated modes of carrying out the disclosure. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the disclosure, since the scope of the disclosure is best defined by the appended claims.
FIG. 1 shows a top-side perspective view of one embodiment of a device 10 for hanging a ceiling panel 12. The ceiling panel 12 may be hung in an aircraft, or in another vehicle, or structure. The device 10 may comprise a clevis 14 and a hinge 16. FIG. 2 shows a top-side perspective view of the clevis 14, while FIG. 3 shows a bottom-side perspective view of the hinge 16. The clevis 14 may be attached to a support structure 18, such as a frame of an aircraft, by bolting using openings 19 in the clevis 14, or using other attachment mechanisms. In other embodiments, the support structure 18 may comprise various portions of an aircraft, vehicle, or structure. The clevis 14 may comprise two side-walls 22 and 24 defining a structure receiving chamber 23, a hinge receiving chamber 25, a pin 26, and a first locking member 28. The pin 26 may extend from one hole 30 in side-wall 22 to another hole 32 in side-wall 24. The first locking member 28 may comprise notch 34 cut into side-wall 22 and notch 36 cut into side-wall 24. In other embodiments, the first locking member 28 may comprise without limitation a boss member, a female member, a male member, and/or another type of member. In still other embodiments, the clevis 14 may be of different types, sizes, orientations, and configurations.
The hinge 16 may be attached to a ceiling panel 12 through bolting or other attachment mechanisms. The hinge 16 may only comprise one integral piece, and may not be attached to any additional linkage members. The hinge 16 may have at least one opening 38 for bolting the hinge 16 to the ceiling panel 12. The hinge 16 may comprise a substantially planar surface 39, a surface 40 extending substantially perpendicular to the substantially planar surface 39, an elongated slot 41, and a second locking member 42. The elongated slot 41 may comprise two, elongated, parallel surfaces 44 and 46. An end 48 of the elongated slot 41 may be angled in the form of a hook. The elongated slot 41 may have been slid over the pin 26 of the clevis 14. The second locking member 42 may comprise boss members 50 and 52 extending out of opposite sides of the surface 40. In other embodiments, the second locking member 42 may comprise without limitations a notch, a female member, a male member, and/or another type of member. The second locking member 42 may be engaged to the first locking member 28 thereby locking the hinge 16 and the ceiling panel 12 into the position 58 shown in FIG. 1. In this position, the hinge 16 may be substantially perpendicular to the clevis 14. In other embodiments, the hinge 16 may be of different types, sizes, orientations, and configurations. It should be noted that the clevis 14 and the hinge 16 may each only comprise one integral piece. This may allow for the attachment of the ceiling panel 12 without using additional linkage members attached to either the clevis 14 or the hinge 16.
FIG. 4 shows a side view of the device 10 of FIG. 1 prior to the hinge 16 being attached to the clevis 14. As shown, the angled end 48 of the elongated slot 41 may be positioned around the pin 26 of the clevis 14 to avoid the hinge 16 coming in contact with a light fixture 60, such as an aircraft stowage light. The elongated slot 41 of the hinge 16 may be slid along the pin 26 of the clevis 14, and pivoted/rotated into the intermediate position 62 shown in FIG. 5. The offset nature of the hinge 16 from the pin 26 may allow the hinge 16, and the attached ceiling panel 12, to be pivotally moved relative to the clevis 14 while avoiding contact with the light fixture 60. The elongated slot 41 of the hinge 16 may be further slid and pivoted along the pin 26 of the clevis 14 into the position 64 shown in FIG. 6. In this position, the second locking member 42 of the hinge 16 may begin to engage the first locking member 28 of the clevis 14. The elongated slot 41 of the hinge 16 may continue to be slid and pivoted along the pin 26 of the clevis 14 so that the first and second locking members 28 and 42 fully engage and lock the device 10 in the position 58 shown in FIG. 1. When the first and second locking members 28 and 42 are fully engaged, the attached ceiling panel 12 is fixedly hung. Subsequently, the hinge 16 may be rotated and pivoted in the opposite direction to disengage the hinge 16 from the clevis 14 to un-hang the ceiling panel 12.
FIG. 7 is a flowchart showing one embodiment 166 of a method of hanging a ceiling panel 12. The ceiling panel 12 may comprise any of the embodiments disclosed herein. In one step 168, a clevis 14 may be attached to a support structure 18 using bolting or other attachment mechanism. The clevis 14 may comprise any of the embodiments disclosed herein. In another step 170, a hinge 16 may be attached to a ceiling panel 12 using bolting or other attachment mechanism. The hinge 16 may comprise any of the embodiments disclosed herein. In still anther step 170, an elongated slot 41 of the hinge 16 may be slid over a pin 26 of the clevis 14. At this time, the hinge 16 may be rotated relative to the clevis 14 thereby avoiding contact with a light fixture 60 or other structure. In yet another step 172, a first locking member 28 of the clevis 14 may be locked to a second locking member 42 of the hinge 16 in order to lock the hinge 16 and the attached ceiling panel 12 into a position 58. In this locked position 58, the hinge 16 may be disposed in a substantially perpendicular position with respect to the clevis 14. The first and second locking member 28 and 42 may comprise any of the embodiments disclosed herein. In an additional step 174, the first and second locking members 28 and 42 may be unlocked, and the hinge 16 may be removed from the clevis 14 to un-hang the ceiling panel 12.
One or more embodiments of the device 10 and/or methods disclosed herein may prevent damage to light fixtures 60, may provide for easier installation of a ceiling panel 12, may provide for easier un-installation of a ceiling panel 12, may avoid using multiple linking members thereby reducing cost, may increase load capabilities, may reduce the number of moving parts, may provide for easier engagement of the parts holding the ceiling panel 12 in place, and/or may reduce one or more other problems of one or more of the other existing devices and/or methods.
It should be understood, of course, that the foregoing relates to exemplary embodiments of the disclosure and that modifications may be made without departing from the spirit and scope of the disclosure as set forth in the following claims.
