FIELD OF THE INVENTION

[0002] The present invention relates to an aircraft divider assembly, and more particularly to an aircraft class divider that includes a removable panel.

BACKGROUND OF THE INVENTION

[0003] In standard aircraft cabin arrangements, the different seating classes are often separated by a class divider. However, to change the appearance of class dividers, typically, the entire divider as to be replaced with a new one. The present invention provides the ability to change portions of the class divider without having to remove the entire assembly.

SUMMARY OF THE PREFERRED EMBODIMENTS

[0004] In accordance with a first aspect of the present invention there is provided a divider assembly that includes a main body portion having a lower section and an upper section and a removable panel having front and back surfaces. The upper section tapers in width in an upward direction and the main body portion includes front and back surfaces. The removable panel is removably secured to the upper section on the front surface of the main body portion. In a preferred embodiment, the upper section includes an opening therethrough that is defined by a border portion and the removable panel spans the opening. The back surface of the removable panel is in contact with the border portion.

[0005] In a preferred embodiment, the upper section has a narrower thickness dimension than the lower section, and the thickness of the upper section and the removable panel is the same or less than the thickness of the lower section. Preferably, a ledge is defined on the front surface of the main body portion by the thicker lower section. In a preferred embodiment, a gap is defined between a bottom surface of the removable panel and the ledge. Preferably, a removable cover strip is positioned to cover the gap. In a preferred embodiment, a bottom portion of the removable panel is removably secured to the upper section by fastening means. Preferably, the cover strip is positioned using a French cleat. In a preferred embodiment, the cover strip includes a hook portion that is engaged with the top of the French cleat. Preferably, a lighted panel is positioned behind the cover strip.

[0006] In a preferred embodiment, a channel is defined at least partially around the upper section. The channel receives at least a portion of the outer edge of the removable panel. Preferably, the upper section further includes a trim extending at least partially

therearound. The trim defines the channel that receives the outer edge of the removable panel. In a preferred embodiment, the divider assembly further includes at least one of a literature pocket module, in-flight entertainment module, cup holder module, coat hook module, tablet holder module or panel module removably secured to the back surface of the main body portion.

[0007] In one embodiment, the present invention is an aircraft partition that includes a

removable or changeable upper panel. The main body portion of the partition includes a trim that extends around the edges and that is preferably made of aluminum or other metal. In another embodiment, the trim can be made of plastic or the like. The aluminum profile wraps around the whole perimeter of the panel and has a U-shape that captures the top and side edges of the upper panel. Preferably, the partition is tapered towards the top (i.e., it is wider at the bottom than it is at the top when viewed from a fore or aft position in an aircraft). Therefore, by sliding the panel down a predetermined distance (e.g., one inch), it clears the trim on either side and can be removed. The partition also includes fixings along the bottom of the panel to stop the panel from dropping down during regular use.

Generally, the panel has a mechanical fixing at the bottom thereof to hold it in position, but it is supported structurally around its perimeter edge (top and side edges) by the U-shaped aluminum extrusion or trim.

[0008] It will be appreciated that, the panel is essentially a wedge that is being slid up into the space or channel created by the trim. In a preferred embodiment, by having the top panel crushed or made to a thinner dimension than the lower section or panel, the smaller dimension panel (e.g., eighth of an inch) can be used to bring the whole panel back up to an inch again so that it is a generally constant thickness all the way through.

[0009] In a preferred embodiment, a trim or narrow panel covers the gap between the upper panel and the lower section or panel. This gap is provided to allow the upper panel to move or slide downwardly so that it clears the trim and can be removed. In preferred

embodiment, the narrow upper panel is secured in place by a French cleat, which has a ledge across its top edge and then has fixings at the bottom (e.g., threaded fasteners, Velcro, screws, slide fittings or the like to lock it in place).

[0010] In use, the present invention provides airlines or other users with the ability to

quickly and easily reconfigure cabin decor panels on aircraft partitions. Generally, the system uses crushed panel technology in combination with a capturing edge trim frame that allows a decor panel (upper panel or section) to be slid into position and secured or locked with mechanical fasteners. In another embodiment, panels or sections on other cabin vertical surfaces (e.g., galleys, stowages and lavatories) can be changeable using the system described herein. The divider assembly can be a full height partition or less than full height.

[0011] In a preferred embodiment, the bottom portion and the upper portion comprise

honeycomb panels (or a single honeycomb panel) and the upper section (or removable panel) is removable therefrom. In a preferred embodiment, the upper panel has a thinner dimension than the lower section. This allows the removable panel to bring the overall dimension of the upper portion of the partition to be about the same as the lower section. Therefore, the upper portion is also referred to herein as the indented portion.

[0012] The removable panel can be an opaque panel that can include branding thereon or a direct view panel, which is transparent or see-through. Preferably, the divider assembly includes an outer trim or rim that is U-shaped and retains the removable panel on the top and sides of the removable panel and a forward facing trim or cover panel that conceals the bottom edge of the removable panel and the gap between the removable panel and a lower portion.

[0013] In a preferred embodiment, the divider assembly (specifically, the upper portion) includes an opening defined therethrough so that a passenger can see through the partition when a direct view panel is used. In another embodiment, the opening can be omitted. The trim defines a channel that captures or retains the top and side edges of the removable panel. In a preferred embodiment, the divider assembly includes means for attaching the cover panel to the upper portion. In the embodiment shown in the drawings, the attachment means is a French cleat that is secured to the main body portion by threaded fasteners or the like. The French cleat is used to locate and support the cover panel. The cover panel overlaps the entire strip of the French cleat for location and support and is then secured in place with mechanical fasteners. The French cleat can have Velcro, adhesive, tape, glue or the like on the front surface thereof so that the cover panel can be attached thereto. In another embodiment, the French cleat can be omitted and the cover panel can be directly connected to the upper portion.

[0014] The removable panel is secured at the bottom thereof to the indented portion. This can be done by threaded fasteners, such as screws, by snaps, buttons, Velcro or other securing device that allows the removable panel to be unattached to the upper portion. In the example shown in the drawings, the removable panel and the upper portion include openings therein for receiving threaded fasteners.

[0015] In a preferred embodiment, the divider assembly includes branding associated with the cover panel. As shown in the figures, a lighted element that says "ecos" is secured to the main body portion. The cover panel includes "ecos" thereon that can be back lit by the lighted element. "Ecos" is only exemplary. Any logo, word, picture, inscription can be included. The removable panel can include a cutout therein for routing the wiring associated with the lighted element.

[0016] The steps for removing the removable panel from the divider assembly 10 are

discussed below. It will be appreciated that these steps are reversed to place the new removable panel in position. Step one includes removing the cover panel from the divider assembly. There is a gap between the bottom edge of the removable panel and the top edge of the lower portion. This gap allows the removable panel to move downwardly. Next, the bottom of the removable panel is unattached to the indented portion. In an exemplary embodiment, this is done by removing the threaded fasteners. Step two includes lowering the removable panel (and closing the gap) until the bottom edge of the removable panel contacts the top edge of the lower portion. In another embodiment, the removable panel can just be lowered without having to contact the top edge of the lower section. When the removable panel is lowered enough that it traverses the, the side and upper edges of the upper panel are removed from or come out of the channel in the trim. This is made possible by the tapered shape of the top portion of the divider assembly.

[0017] Step three includes continuing to lower the removable panel by pulling forward and slightly away from the lower section so that the bottom edge of the removable panel clears the top edge of the lower section. Next, the removable panel can be removed and is now completely free of the partition.

[0018] In another embodiment, includes the main body portion of the divider assembly includes a downwardly extending foot that attaches to the seat tracks in the floor of the cabin. Preferably, the foot spaces the bottom of the main body portion from the floor to provide room for passengers' feet. Preferably, the main body portion also includes an upwardly extending connector for connecting to the ceiling or wall of the cabin. A connector can also extend from the side of the main body portion.

[0019] In a preferred embodiment, the divider assembly can include outlets or ports (e.g.,

USB) for providing electrical and/or data communication with personal devices, such as tablets, phones or other computer devices. In an embodiment, the upper panel can include LED lighting therearound or therein to emphasize any branding thereon.

[0020] In a preferred embodiment, the partition is customizable and modular. Customizable means that the partition can be customized depending on the customer's (e.g., airline's) desires. Also, it is preferably modular, meaning that the cover panels can be changed or switched out when they are worn out, dirty or to update the look of the aircraft. Different materials or looks or branding can be included on the different cover panels. Airlines are then able to change the cabin atmosphere without changing the entire divider assembly. Therefore, it should be understood that the partition shown in the attached drawings and described herein is only exemplary and that many changes and customizations can be made to the invention.

[0021] In another embodiment, TV screens can be built into or attached to the partition. In an embodiment, the removable cover panel or module on at least one of the sections (e.g., the lower section) can include literature pockets thereon. The modules can include a literature pocket module, a passenger accessories module (e.g., phone, USB, tablet holder), a crew accessories module or an in-flight entertainment module, etc.

[0022] The invention, together with additional features and advantages thereof, may be best understood by reference to the following description.

[0041] Referring now to the drawings, which are for purposes of illustrating the present invention and not for purposes of limiting the same, the attached drawings show an aircraft partition or divider assembly 10. The divider assembly 10 is positionable between rows of seats 100 or other components (lavatories, closets, galleys, etc.) in an aircraft cabin 102 to divide sections or classes of the aircraft. For example, the divider assembly 10 can be positioned or mounted between first and coach classes.

[0042] FIG. 1 shows the divider assembly 10 mounted in the interior of an aircraft. In a preferred embodiment, the divider assembly 10 generally includes a main body portion 12 having front and back surfaces 12a and 12b, a lower section 14 and an upper section 16. In a preferred embodiment, the upper section 16 tapers in width in an upward direction (towards the ceiling of the aircraft). In other words, as shown in FIG. 2, the upper section 16 defines a bottom width Wl and a top width W2 and the top width W2 is narrower than the bottom width Wl .

[0043] As shown in FIG. 2, the divider assembly 10 generally includes the main body

portion 12, a removable panel 18 having front and back surfaces 18a and 18b, a cover strip 20, a French cleat 22 and a light assembly or lighted panel 24. In a preferred embodiment, the removable panel 18 is removably secured to the upper section 16 on the front surface 12a of the main body portion 12. In other embodiments, the removable panel can be secured to the back surface 12b of the main body portion 12 or to either side of the lower section.

[0044] With reference to FIGS. 2-4D, in a preferred embodiment, the upper section 16 has a narrower thickness dimension than the lower section 14. This allows the removable panel 18 to be secured to the upper section 16 without increasing the overall thickness of the main body portion 12. Preferably, the thickness of the upper section 16 and the removable panel 18 together is the same or less than the thickness of the lower section 14. Because of the thickness difference, the upper section is also referred to herein as the indented section or portion. Also, because of the thickness difference, a ledge 26 is defined on the front surface 12a of the main body portion 12 by the thicker lower section 14. The ledge 26 spans the width of the main body portion 12. In another embodiment, the ledge may only span a portion of the width of the main body portion 12.

[0045] It will be appreciated that the removable panel 18 can be opaque or transparent/see- through. In a preferred embodiment, the upper section 16 includes an opening 28 therethrough that is defined by a border portion 30. A frame 31 can also be included to help define opening 28 and for aesthetic purposes. The border portion 30 is essentially the solid portion of the upper section 16. The removable panel 18 spans the opening 28 and the back surface 18b of the removable panel 18 is secured against or in contact with the border portion 30.

[0046] As shown in FIG. 2, in a preferred embodiment, the bottom portion of the removable panel 18 is removably secured to the upper section by fastening means. Any method for securing the removable panel 18 to the upper section 16 (or any section of the main body portion 12) is within the scope of the present invention. In a preferred embodiment, threaded fasteners 32 are secured through holes in the removable panel 18 and are threaded into holes in the main body portion 12. However, in other embodiments, the fastening means can be non-threaded fasteners, rivets, adhesive, glue, tape, welding or the like. It will be appreciated that the fastening means can also be used to secure the sides and/or the top of the removable panel 18. However, in a preferred embodiment, as shown in FIGS. 2 and 4A-4B, the side and top edges 18d and 18e of the removable panel 18 are received in and secured by a channel 34 that is defined by trim 36 that extends around the outside of the upper section 16 or the entire main body portion 12. Channel 34 can be defined by components other than trim. For example, the channel can be defined directly in the main body portion 12 or include a component inboard of the trim.

[0047] As is best shown in FIG. 4D, a gap 38 is defined between the bottom edge 18c of the removable panel and the ledge 26. This gap 38 allows the removable panel 18 to move downwardly when being removed, as further described below. In a preferred embodiment, the cover strip 20 is positioned to cover the gap 38 (and the threaded fasteners 32). As shown in the figures, the cover strip 20 is secured in place by the French cleat 22. The French cleat 22 is secured to the main body portion 12 and/or the upper section 16 by fasteners, threaded fasteners, adhesive, glue, tape, welding, quick release fasteners, spring biased clips or other attachment method. The cover strip 20 is secured to the front surface of the French cleat 22 by the Velcro, tape, adhesive, threaded fasteners or the like. As shown in FIGS. 4C and 4D, the cover strip 20 can also include a hook portion 40 on the top thereof that hooks over the top edge of the French cleat 22 to help secure the cover strip 20 in place. In another embodiment, the French cleat can be omitted and the cover strip 20 can be directly connected to the main body portion 12 and/or the upper section 16 or the removable panel 18. The French cleat 22 can also be used to hold or secure the bottom of the removable panel 18. As shown in FIG. 4C, the French cleat defines a trough 42 that receives the bottom portion of the removable panel 18.

[0048] In another embodiment, the French cleat 22 can be omitted, the threaded fasteners 32 securing the bottom of the removable panel 18 can be omitted, and the cover strip 20 can be used to secure the bottom of the removable panel 18 in place. In this embodiment, once the cover strip 20 is removed the removable panel 18 is free to move downwardly so that it can be removed from the main body portion 12 and/or the upper section 16.

[0049] In a preferred embodiment, the divider assembly 10 includes upper and lower

attachment portions 44 and 46 for securing the divider assembly 10 to the floor of the aircraft cabin and/or the ceiling or any component above the main body portion 10. As shown in FIGS. 1 -3, the lower attachment portions 44 can be spaced such that they attached to the seat attachment tracks on the floor of the aircraft cabin 102 and the upper attachment portion 46 can include posts that extend upwardly and attached to the personal service unit rails associated with the overhead storage bins. The removable panel 18 can include a cutout 18f defined therein that surrounds or makes room for the upper attachment portion 46.

[0050] In a preferred embodiment, the divider somewhere 10 includes the lighted panel 24 positioned behind the cover strip 20. Preferably, the cover strip 20 includes inscribed writing, a transparent portion or other indicia 48 that is backlit by the lighted panel 24. The removable panel 18 can include a cutout 18g therein that receives the lighted panel 24 and allows wiring to be routed therethrough. The lighted panel 24 and indicia 48 on the cover strip 20 can be used for advertising purposes.

[0051] FIGS. 5A-5E show exemplary steps for the removal of removable panel 18 from the divider assembly 10. First, as shown in FIG. 5 A, the cover strip 20 is removed from the French cleat 22 (or main body portion 12 if it is connected directly thereto). Next, as shown in FIG. 5B, the French cleat 22 is removed from the main body portion 12. Next, as shown in FIG. 5C, the removable panel 18 is moved downwardly, thereby closing the gap 38, until the bottom edge 18c is close to or in contact with ledge 26. When this happens the side and top edges of the removable panel 18 move partially or all the way out of the channel 34. Next, as shown in FIG. 5D, the bottom of the removable panel 18 is pulled outwardly so that it clears the ledge 28 and the entire removable panel 18 is moved downwardly so that the side and top edges of the removable panel 18 clear the channel. Next, as shown in FIG. 5E, the removable panel 18 is removed from the main body portion 12 of the divider assembly 10. It will be appreciated that these steps can be changed. For example, in an embodiment where the cover strip holds the bottom of the removable panel in place, the step shown in FIG. 5B can be omitted.

[0052] FIGS. 6-7 show an embodiment of the divider assembly 10 that includes modules on the back or aft side. It will be appreciated that the modules described herein are optional. In another embodiment, the divider assembly can include the modules and no removable panel.

It will be appreciated that the term module is used herein to indicate that the modules can be removed and replaced with different or other modules. The various modules can be used by occupants of the seats on the back or aft side of the divider assembly 10.

[0053] In a preferred embodiment, each of the literature pocket modules 52 can be removed separately. In another embodiment, the literature pocket modules 52 can be part of a single panel and removed together. Preferably, the main body portion 12 includes a crush or indentation 62 therein (or a separate indentation for each module). Male connectors are attached to the back of the literature pocket modules 52 and mate with openings 64 in positioned in the indentation 62. The embodiment shown in the drawings includes three openings on the right and three opening on the left for each literature pocket module 52. In another embodiment, the male connectors can be positioned in the indentation and the openings can be in the back of the modules. Any connection methodology is within the scope of the present invention. For example, the connection can be made via mechanical fixings, press stubs, snap fit, friction fit, threaded fasteners, Velcro, adhesives, quick release fasteners, etc. Any of the modules discussed herein can be secured in place using any of the described attachment methods or others known to those of skill in the art.

[0054] The literature pocket modules 52 can be replaced with other modules. For example, as shown in FIG. 7, a panel module 60 (e.g., aesthetically pleasing wood paneling) can take the place of the literature pocket modules 52 if the divider assembly 10 is moved to a position where literature pockets are unnecessary.

[0055] The cup holder module 54, coat hook module 56 and tablet holder module 58 can be disposed in openings 66 defined in the main body portion 12 and secured in place with threaded fasteners or the like. In another preferred embodiment, the cup holder module 54, coat hook module 56 and tablet holder module 58 can be disposed at the bottom of the IFE panel 50 and secured in place with mechanical fasteners or the like (to the IFE panel or the main body portion 12). Each of these modules can include a flange 68 for alignment and attachment purposes. The tablet holder module 58 can include a port (e.g., a USB port) therein. The modules can be permanently attached to the main body portion 12 or can be removable. In another embodiment, the cup holder module 54, coat hook module 56 and tablet holder module 58 or any combination thereof (e.g., three cup holders for the three passengers) can be mounted or part of an accessories rail that spans most of the main body portion 12. The accessories rail can be secured to the main body portion or be attached to the IFE module (e.g., the backplate 70). Also, the individual modules 54, 56 and 58 can be secured to the IFE module, the main body portion 12, the monitor frame 50, the rail or the branding strip 20.

[0056] In a preferred embodiment, the IFE module 50 includes a frame or backplate 70
