One piece decorative insulation and interior panel assembly
An insulated wall for a mobile platform is formed from at least two layers. A first layer includes an insulation material. A second layer includes a flexible material having an outer face with a decorative pattern and an inner face attached to the first layer. The wall is mounted in the mobile platform with the outer face of the second layer having the decorative pattern forming a mobile platform innermost facing surface. By attaching a flexible material layer to the insulation material, the insulated wall can be formed into rolls and rolled out during installation in a single step. In another embodiment, fasteners are preinstalled in the wall for fastening the wall to the mobile platform. In yet another embodiment, a method for insulating a compartment of a mobile platform is provided.
The present invention relates in general to insulation and more specifically to insulation systems for mobile platforms.
BACKGROUND OF THE INVENTIONInsulation systems for modern mobile platforms are typically installed having at least one layer of insulation material connected to the inside facing surface of an outer shell of the mobile platform. Both to protect the insulation layer and to provide a durable working surface, a separate layer of rigid or semi-rigid material is then placed over the insulation layer and fastened to the structure of the mobile platform. The insulation is required where the mobile platform is required to operate in low-temperature applications and also provides a sound barrier. For purposes of illustration only, insulation systems applied to commercial aircraft will hereinafter be described in reference to the mobile platform.
Modern commercial aircraft are constructed having a thin outer skin and a plurality of internal frames or ribs supporting the skin. Because the aircraft is exposed during operation to extremely low external temperatures, insulation is applied to the interior facing surfaces of the outer skin. Insulation on commercial aircraft is typically applied in one of two ways. In a first method, insulation is applied directly to the outer skin on the inner facing edge of the skin. In a second method, insulation is applied to the outer facing surfaces of the interior cabin wall panels attached to the frames of the aircraft. To protect the insulation and provide a sealed, durable, and decorative interior surface, commercial aircraft commonly install rigid or semi-rigid composite wall sections over the insulation layer(s).
The above methods to both insulate and seal the exterior skin of commercial aircraft have several disadvantages. Installation of the one or more insulation layers requires separate installation steps from that used to later install the layer of composite over the insulation. This increases the overall labor cost to manufacture each aircraft. Further, the composite walls that are used require individual tooling to shape the composite walls to conform to the shape of the aircraft adjacent to the frames and structural components. In addition, because it is undesirable for fasteners used to mount the composite walls to be visible following installation, fasteners to mount the composite walls are typically provided on exterior facing surfaces of the composite walls. Providing fasteners in these locations requires that the fasteners be pre-aligned with support structure of the aircraft. Due to the rigid nature of the composite wall surfaces, any misalignment of the fasteners requires additional time and expense during the insulation process to provide proper alignment and installation of the wall. Additional cost is also incurred by the separate tooling required for the composite wall sections to accommodate the variety of geometry changes in a commercial aircraft due to bulkhead wall locations, overhead luggage compartment locations, and both window and emergency exit locations. Unique tooling is also required for NC trimming of the composite part and also for vacuum forming the decorations in or on the surface of the composite part. This variety of molding tools adds further expense to the construction cost of each aircraft.
It is therefore desirable to provide an insulation system and a method of installation which overcomes the disadvantages noted above. It is also desirable to decrease the number of individual components required to insulate a mobile platform.
SUMMARY OF THE INVENTIONAccording to a preferred embodiment of the present invention, a one piece insulated wall for a mobile platform is provided. The one piece insulated wall includes a first layer having insulation material. A second layer includes a flexible material having an outer face defining a decorative pattern and an inner face attached to the first layer. The one piece insulated wall is mountable in the mobile platform such that the outer face of the second layer defines an innermost facing surface.
In another preferred embodiment of the present invention, a plurality of composite mounting fasteners are each connected at a fixing end to only the first layer. Each of the fasteners includes a distal connecting end freely extending from the first layer in a direction facing away from the second layer. The distal connecting end operates to connectably join the wall to the mobile platform.
In still another preferred embodiment of the present invention, a mobile platform comprises an exterior skin defining at least one interior compartment. A composite wall is conformable to a shape of the exterior skin and connectable to the exterior skin within the interior compartment. The composite wall includes at least one insulation layer and a flexible layer attachable to the insulation layer. The flexible layer operably forms an interior boundary surface of the interior compartment when the composite wall is connected to the exterior skin having the insulation layer facing the exterior skin.
In yet another preferred embodiment of the present invention, a method of insulating a compartment of a mobile platform is provided. The method uses a one piece insulated wall having a flexible material layer attachable to an insulation layer. The method steps include forming a decorative pattern on a first face of the flexible material layer. The insulation layer is attached to a second face of the flexible material layer. The decorative pattern is then oriented toward the interior compartment of the mobile platform. Finally, the insulated wall is connected to the mobile platform having the insulation layer facing an exterior surface of the mobile platform.
Further areas of applicability of the present invention will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the invention.

To install an insulation panel 12 of the present invention, a plurality of fasteners 50 are first installed in insulation panel 12. Each fastener 50 has its connecting end 62 aligned with a mating one of fastener apertures 52 formed in frame cross members 28. Fastener 50 is thereafter pressed in the fastener installation direction “C” until bulbous ends 64 of fastener 50 compress in the fastener compression direction “D” in fastener aperture 52 to allow bulbous end 64 to pass within fastener aperture 52. A spring force of fastener 50 at connecting end 62 thereafter expands bulbous ends 64 to releasably retain fastener 50 in contact with frame cross member 28.
In an alternate embodiment (not shown), fastener 50 can be formed as a known male type metallic or polymeric snap fastener. Fastener aperture 52 is replaced in this embodiment with a female snap fastener element to receive the male snap fastener element installed on the first layer 14. Elements of the snap fastener can also be reversibly attached, having the female snap fastener member installed on the first layer 14. Additional embodiments for fastener 50 include, but are not limited to, blind rivets, Christmas tree shaped or barbed polymeric material fasteners, and expandable wing-type fasteners. It is preferable that any fastener 50 form a releasable joint when connected to frame cross member 28. This permits removal of insulation panels 12 for repair, replacement, maintenance, and/or cleaning.

An insulation system of the present invention offers several advantages. By combining the insulation layer(s) with a flexible interior facing layer, insulation can be applied from a rolled coil, which reduces labor during installation. The flexible inner layer of the present invention also replaces the need for mold tooling to develop individual pieces of the inner wall now used on common commercial aircraft. By attaching only perimeter areas of the insulation material to the flexible lining, the coiled insulation panel can be conformed to the shape of an interior surface having curved surfaces or non-linear surfaces without resulting in a wrinkled appearance. By pre-installing fasteners only in the insulation layers, the insulation panel of the present invention can be installed such that fasteners are not visible from a passenger side of the installed insulation panel. Finally, by combining the insulation layer or layers with the flexible material of the present invention, a one-piece simplified removal assembly is provided which affords easy removal of the insulation for maintenance and/or cleaning.
The description of the invention is merely exemplary in nature and, thus, variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention. For example, the mobile platform referred to herein can also include train cars, busses, automobiles, military vehicles, space vehicles, etc. The invention is not limited to the mobile platform type. Although the insulation panel of the present invention is preferably removably installed, at least one border of an insulation panel of the present invention can also be permanently installed without departing from the spirit and scope of the invention.
