Description

Technical Field

[0001] The present disclosure relates generally to floor covering panels, and more particularly to interlocking floor covering panels that are collectively coupled together such that all coupled floor covering panels are capable of relative movement in a coupled manner. Background Art

[0002] Cabin floors for commercial and military aircraft typically comprise a structural sub-floor with a thin laminate covering followed by a top floor covering sealed to the thin laminate covering. A moisture barrier tape can also be provided along the sub-floor.

[0003] In this prior art design, double sided tape is laid over the entire subfloor area where the rigid laminate sections are laid and sealed. Then, a second layer of double sided tape is laid over the laminate sections, followed by the top floor covering pad. This technique for forming the floor covering described above can be time consuming and difficult to repeat in a production environment. In addition, since the pad is typically constructed of a single continuous piece, it can be difficult to replace or repair individual floor covering sections. Typical installations of laminates and pads (currently produced) also suffer from the problem of pad buckling during flight.

[0004] Therefore, there is a need for a new floor covering system that enables reduced installation time, increased reliability and repeatability of installation, and allows for improved appearance, increased durability, and the ability to replace individual panels. Summary of the invention

[0005] In one example, a floor covering system in a passenger vehicle is described. The floor covering system includes: a plurality of floor covering panels positioned adjacent to one another to create interfaces between respective ones of the plurality of floor covering panels; a plurality of joint panels positioned below one or more of the interfaces, and the plurality of floor covering panels are rigidly coupled to at least one of the plurality of joint panels to prevent relative movement between the plurality of floor covering panels; and a plurality of attachment mounts attached to a structure of the passenger vehicle. Each of the plurality of floor covering panels is coupled to one or more of the plurality of attachment mounts, and the plurality of attachment mounts enable lateral movement of the plurality of floor covering panels together in a coupled manner relative to the structure of the passenger vehicle.

[0006] In another example, an aircraft including a floor covering system is described.

[0007] In yet another example, a method for installing a floor covering system in a passenger vehicle is described. The method includes: mounting a plurality of attachment mounts to a structure of the passenger vehicle; positioning a plurality of floor covering panels adjacent to each other to create an interface between respective ones of the plurality of floor covering panels; rigidly coupling the plurality of floor covering panels to at least one of a plurality of joint panels positioned below the interface to prevent relative movement between the plurality of floor covering panels; and coupling each of the plurality of floor covering panels to one or more of the plurality of attachment mounts. The plurality of attachment mounts enable lateral movement of the plurality of floor covering panels together in a joined manner relative to the structure of the passenger vehicle.

[0009] Various examples of a method(s) described herein may include any components, features, and functions of any other example of a method(s) described herein, in any combination.

[0025] The disclosed examples are now described more fully below with reference to the accompanying drawings, but some, but not all, disclosed examples of the present invention are shown therein. However, a variety of different examples may be described and should not be considered limited to the examples presented here. Rather, these examples are described so that the present disclosure will be thorough and comprehensive and fully convey the scope of the present disclosure to those skilled in the art.

[0026] In the examples herein, components for aircraft interiors and specifically floor coverings are described. For a long time, there has been a desire to use hardwood or solid wood flooring on aircraft, especially in some premium cabin areas. However, hardwood or solid wood flooring can be impractical because aircraft floors must be able to withstand a certain vertical load (e.g., about three times the force of gravity), but hardwood flooring is heavy and thus causes unnecessary extra weight on the aircraft, air pockets in the adhesive expand over time, making the surface uneven when the aircraft is at high altitude (e.g., lower pressure), hardwood flooring generally does not absorb noise like carpet, and spills can create a slip hazard on such floors.

[0027] Additionally, subfloors on aircraft move, making traditional hardwood or solid wood flooring impractical, and movement of subfloors can cause buckling of floor coverings attached thereto. For example, during a flight cycle, the floor structure moves outward due to pressure differentials, and then moves backward due to thermal contraction as altitude changes. Aircraft motion is cyclical, and over time will likely cause buckling of traditional hardwood flooring. This is caused by the high adhesion tape applied between the laminate and the structural flooring that holds the laminated hardwood. Therefore, given these and other factors, there is a need to provide the look and feel of hardwood flooring on aircraft.

[0028] Now referring to the accompanying drawings, Figure 1A 1 is a top view of an example of a floor covering system 100 in a passenger vehicle according to an exemplary embodiment. In the example herein, the passenger vehicle comprises an airplane ( Figure 5 As shown), however, the passenger vehicle can be or include various types of vehicles, such as ships, trains, cars, etc.

[0029] The floor covering system 100 includes a plurality of floor covering panels 102 positioned adjacent to one another thereby creating interfaces 104 between respective ones of the plurality of floor covering panels 102 . Figure 1A Only one interface 104 is labeled, but interfaces exist between floor covering panels 102 that abut other floor covering panels 102. The floor covering system 100 also includes a plurality of joint panels 106 positioned beneath one or more of the interfaces 104. Figure 1A Only one connector panel 106 is labeled and illustrated, but the connector panel is included below many interfaces 104 ( Figure 5 1. Further examples are shown in FIG. 1. The plurality of floor covering panels 102 are rigidly coupled to at least one of the plurality of joint panels 106 to prevent relative movement between the plurality of floor covering panels 102. The floor covering system 100 also includes a structure 110 ( Figure 31 ). Each of the plurality of floor covering panels 102 is coupled to one or more of the plurality of attachment mounts 108, and the plurality of attachment mounts 108 enable lateral movement of the plurality of floor covering panels 102 together in a combined manner relative to the structure 110 of the passenger vehicle. Figure 1A Only one attachment mount 108 is labeled and illustrated, but many attachment mounts are included below the floor covering panel 102 ( Figure 5 Further examples are shown in ).

[0030] The floor covering system 100 also includes a plurality of edge panels 112 surrounding the plurality of floor covering panels 102. The plurality of edge panels 112 are connected by additional joint panels ( Figure 6B ) are coupled to the plurality of floor covering panels 102. Figure 1A In the example, the plurality of edge panels 112 may surround all perimeters of the plurality of floor covering panels 102. In other examples, depending on the layout of the floor covering system 100, the plurality of edge panels 112 may only surround a portion of the perimeters of all floor covering panels in the plurality of floor covering panels 102, such as Figure 1A For example, the plurality of edge panels 112 surround the plurality of floor covering panels 102 to form a picture frame shape.

[0031] The plurality of floor covering panels 102 also include a plurality of slats 114 positioned on each of the plurality of floor covering panels 102 in a staggered configuration. Figure 1B , one floor covering panel 102 is shown separated from the floor covering system 100 at the upper right to illustrate the floor covering panel 102 having a plurality of planks 114. The plurality of floor covering panels 102 include borders that follow a hardwood floor pattern to provide a discrete part interface, and on the plurality of floor covering panels 102, the plurality of planks 114 also include borders that follow a hardwood floor pattern. The plurality of floor covering panels 102 can be viewed as being configured in a male or female form so that they interlock with each other.

[0032] In an example, each floor covering panel 102 may be approximately eight feet long (or shorter) due to raw material size limitations and the ability to fit in place on a fully equipped aircraft. The width of the individual slats 114 is approximately six inches to allow for smooth installation of the floor panel edges. Such dimensions are used to simulate a hardwood floor layout and the slats 114 can be positioned with a gap of approximately 0.09 inches wide between each slat. The length of the slats 114 may be approximately four feet long.

[0033] The specific arrangement and position of the plurality of floor covering panels 102 in the floor covering system 100 can vary depending on the design of the passenger vehicle. In addition, the specific arrangement and position of the plurality of slats 114 in the plurality of floor covering panels 102 can vary depending on the design of the passenger vehicle.

[0034] The plurality of floor covering panels 10 include composite panel materials. In some examples, the plurality of floor covering panels 102 include multiple layers, such as a rubber sound-absorbing layer, a fiberglass foam core structural composite layer, an artwork substrate and an artwork film, and a durable polymer textured surface layer capable of simulating the appearance of hardwood floors. Therefore, it is desirable that the top surface of the plurality of floor covering panels 102 is an anti-skid surface to meet certain requirements, and below the anti-skid surface can be a decorative surface layer (e.g., presenting a wood grain embossed thereon, a wood grain texture printed thereon, or any other desired aesthetically pleasing surface pattern).

[0035] Figure 2 is a side perspective view of a portion of a floor covering system 100 according to an exemplary embodiment. Each floor covering panel 102 includes an interlocking feature 113 extending outwardly from a body 116 to slidably engage a corresponding joint panel 106. In the example, the interlocking feature 113 extends along an end of the body 116.

[0036] The interface 104 between the respective floor covering panels 102 comprises a gap. The gap is, for example, a space that can accommodate building tolerances.

[0037] The plurality of joint panels 106 provide a common surface for bonding and sealing of the plurality of floor covering panels 102. The plurality of floor covering panels 102 can be bonded or sealed to the plurality of joint panels 106 by using double-sided tape, for example, at interlocking features 113. By connecting the plurality of floor covering panels 102 to the plurality of joint panels 106, the plurality of floor covering panels 102 are connected to each other so as to prevent any relative movement between the plurality of floor covering panels 102.

[0038] Figure 3 is a side view of a portion of a floor covering system 100 according to an exemplary embodiment. Figure 3 , the floor covering panel 102 is shown attached on each side to a three-dimensional structural interface panel 118. Each three-dimensional structural interface panel 118 is connected to the structure 110 of the passenger vehicle by using magnets and P-type seals to create a sealed joint 120. In this example, the structure 110 of the passenger vehicle is, for example, a structural floor.

[0039] The plurality of attachment mounts 108 are rigidly attached to a structure 110 of the passenger vehicle. Figure 3, an attachment mount 108 is shown. The plurality of attachment mounts 108 can be rigidly attached to the structure 110 of the passenger vehicle by using adhesive or tape. The plurality of floor covering panels 102 are then coupled to the attachment mount 108 by snap fit or other mechanical assembly (e.g., screwing together, bolting, etc.). The plurality of floor covering panels 102 are coupled to the three-dimensional structural interface panel 118 by using tape as shown at the interface 104, and a strip of sealant 122 can be applied in the gap of the interface 104.

[0040] Figure 4 is a side view of another portion of the floor covering system 100 according to an exemplary embodiment. Figure 4 , an attachment mount 108 is shown that includes a first portion 124 that is rigidly attached to the structure 110 of the passenger vehicle and a second portion 126 that is coupled to the corresponding floor covering panel 102. The second portion 126 has lateral freedom of movement relative to the first portion 124. Figure 4 As shown, the second portion 126 is smaller than the first portion 124 and can slide laterally within the recess of the first portion 124. The second portion 126 can be mounted on a track within the recess, which can include a spring to enable lateral movement. The second portion 126 can also be coupled to the first portion 124 in other ways, such as by a mechanical slot, a snap fit, a spring-loaded screw mechanism, or other means.

[0041] In the floor covering system 100, the plurality of attachment mounts 108 prevent vertical movement of the plurality of floor covering panels 102. Because the plurality of floor covering panels 102 are coupled to the plurality of attachment mounts 108, vertical movement is not possible. However, the plurality of attachment mounts 108 enable lateral movement, but the plurality of attachment mounts 108 typically limit lateral movement to, for example, less than about 0.2 inches. When subjected to a load of nine times the force of gravity in a forward direction and three times the force of gravity in an upward direction, the floor covering system 100 is limited to no further lateral movement and is limited to no vertical movement, as defined by the requirements for holding a large number of items.

[0042] In a further example, the plurality of attachment mounts 108 enable the plurality of floor covering panels 102 to achieve lateral movement of up to about 0.2 inches together in a combined manner. Thus, in an example, relative movement between each of the plurality of floor covering panels 102 is individually restricted, but lateral movement of the plurality of floor covering panels 102 together in a combined manner is permitted. This is because the plurality of floor covering panels 102 are coupled together by the plurality of joint panels 106. In this manner, the plurality of floor covering panels 102 are effectively bonded together as a monolithic object that is dynamically attached to the structure 110 to accommodate relative movement between the monolithic object and the structure 110. The plurality of attachment mounts 108, for example, serve as a lateral floating attachment of the monolithic object.

[0043] Thus, in the examples herein, the floor covering system 100 enables the plurality of floor covering panels 102 to float (eg, move laterally freely) in a bonded manner above an aircraft subfloor (eg, the structure 110 of the aircraft).

[0044] The dynamics and loads placed on the floor covering system 100 due to the aircraft being in flight require that the floor covering system 100 must withstand certain forces (e.g., a force pulling upwards of approximately three times its own weight, and a force pulling forwards of approximately nine times its own weight). Thus, the floor covering system 100 enables compliance with these dynamics of the aircraft's dynamic loading requirements (e.g., flight loads and thermal contraction at a certain altitude). By allowing the plurality of floor covering panels 102 to move together as a unitary component relative to the structure 110, the floor covering system 100 is allowed to float laterally thereby removing stresses on the floor covering system 100 due to the dynamics of aircraft operation.

[0045] Figure 5 A schematic layout of a floor covering system 100 in accordance with an exemplary embodiment is shown in a portion of an aircraft 130. Figure 5 , various areas of an aircraft 130 are shown including a galley area and a seating area. Figure 5 A specific layout is shown for a specific aircraft design, wherein floor covering systems 100 are positioned throughout the area.

[0046] exist Figure 5 In the example, only one floor covering panel 102 is marked, but Figure 5 The floor covering system 100 is similar to Figure 1A As shown in Figure 5 As shown, each of the plurality of floor covering panels 102 is coupled to a plurality of attachment mounts 108. For example, in Figure 5The floor covering panels 102 labeled in FIG. 1 are coupled to eight different attachment mounts 108. The number and layout of the attachment mounts 108 for each floor covering panel can vary and may depend on the bond strength of the attachment mounts to the structure 110. Additionally, the number and layout can depend on how much shear force (e.g., lift force) each attachment mount 108 can handle and the weight of the floor covering panel 102.

[0047] exist Figure 5 106. In the embodiment of the present invention, a special floor covering panel is not coupled to any attachment mount, namely, the electronics hatch cover 132. Instead, magnets 134 are used to secure the electronics hatch cover 132 to the structure 110 to enable access during floor maintenance. The magnets 134 provide retention while still allowing some lateral displacement. In addition, the electronics hatch cover 132 is not coupled to any of the plurality of connector panels 106. Instead, a gasket, for example, is used to seal the electronics hatch cover 132 to the structure 110.

[0048] Fig. 6A According to an exemplary embodiment, Figure 5 A view of a portion of aircraft 130 is shown in FIG. Figure 6B According to an exemplary embodiment, Fig. 6A An enlarged view of a portion of the aircraft shown. Figure 6B 1, the joint panel 106 is shown as being between the ends of two adjacent floor covering panels 102. Further, in the illustrated arrangement, the plurality of floor covering panels 102 are positioned adjacent to one another so as to longitudinally create a side interface 136 between respective ones of the plurality of floor covering panels 102, and the floor covering system 100 includes a plurality of side joint panels 138 positioned below the side interface 136. Each of the plurality of floor covering panels 102 is rigidly coupled to at least one of the plurality of side joint panels 138 to prevent relative movement between the plurality of floor covering panels 102. In this example, the plurality of floor covering panels 102 are attached to all adjacent components (whether it is another floor covering panel or an edge panel 112). The interconnection between all panels creates an integral structure in which the components of the floor covering system 100 are prevented from moving relative to one another. Instead, the plurality of floor covering panels 102 can move together in a lateral motion, as permitted by the plurality of attachment mounts 108.

[0049] Figure 7-14 An exemplary three-dimensional structural interface for a floor covering system 100 is shown in accordance with an exemplary embodiment. Figure 7, a three-dimensional structural interface 140 is shown for a video control center (VCC) inside the aircraft 130. At the three-dimensional structural interface 140, at least one of the plurality of slats 114 extends outward and overhangs the corresponding floor covering panel 102 to form an extension of the at least one of the plurality of slats 114, and the extension of the at least one of the plurality of slats 114 slides under the three-dimensional structural interface 140.

[0052] exist Fig.10 In the embodiment, the three-dimensional structural interface 140 includes a kickstrip, and an example is shown in which an extension of the at least one slat of the plurality of slats 114 slides under the three-dimensional structural interface 140 .

[0053] exist Fig.11 In the example, the three-dimensional structural interface 140 includes a door mop sill, and in this example, at least one of the plurality of slats 114 extends outwardly and overhangs the corresponding floor covering panel 102 to form an extension of the at least one of the plurality of slats 114, and the extension of the at least one of the plurality of slats 114 overlaps the three-dimensional structural interface 140.

[0054] exist Fig.12 In the embodiment, the three-dimensional structural interface 140 includes a door sill, and an example is shown in which an extension of the at least one slat of the plurality of slats 114 slides under the three-dimensional structural interface 140 .

[0055] exist Fig.13 In the embodiment, the three-dimensional structural interface 140 includes a suite threshold, and an example is shown where an extension of the at least one slat of the plurality of slats 114 slides under the three-dimensional structural interface 140 .

[0058] Fig.15 A flow chart illustrating an example of a method 200 for installing a floor covering system 100 in a passenger vehicle according to an exemplary embodiment. Fig.15 The method 200 shown in FIG. 1 represents a method that can be used, for example, with Figure 1A The floor covering system 100 shown may be used with and / or in Figure 5 An example of a method used in the aircraft 130 shown. In some cases, components and / or equipment may be configured to be used in function so that the components are actually configured and constructed to enable such performance. In other examples, components and / or equipment may be configured to be debugged to be able to or suitable for the performance of the function. Method 200 may include one or more operations, functions or actions as shown in one or more of blocks 202-208. Although the blocks are shown in a continuous order, these blocks may also be executed in parallel and / or in a different order than described herein. Similarly, based on the implementation, various blocks may be combined into fewer blocks, divided into additional blocks and / or removed.

[0059] It should be understood that for this and other processes and methods disclosed herein, the flowchart illustrates the functionality and operation of one possible implementation of this example. Alternative implementations are included within the scope of the examples disclosed herein, wherein the functions may be performed in a different order than shown or discussed (including substantially simultaneously or in reverse order) based on the functions involved as understood by a reasonable person skilled in the art.

[0060] At frame 202, the method 200 includes attaching a plurality of attachment mounts 108 to a structure 110 of a passenger vehicle. At frame 204, the method 200 includes positioning a plurality of floor covering panels 102 adjacent to one another, thereby creating an interface 104 between respective ones of the plurality of floor covering panels 102. At frame 206, the method 200 includes rigidly coupling the plurality of floor covering panels 102 to at least one of a plurality of joint panels 106 positioned below the interface 104 to prevent relative movement between the plurality of floor covering panels 102. At frame 208, the method 200 includes coupling each of the plurality of floor covering panels 102 to one or more of the plurality of attachment mounts 108, and the plurality of attachment mounts 108 enable lateral movement of the plurality of floor covering panels 102 together in a coupled manner relative to the structure 110 of the passenger vehicle.

[0061] Fig.16A flow chart is shown of an exemplary method for use with the method 200 according to an exemplary embodiment. At block 210, the method 200 includes interlocking the respective floor covering panel 102 with the at least one of the plurality of joint panels 106 via an interlocking feature 113 extending outwardly from a body of the respective floor covering panel 102 for slidably engaging the respective joint panel 106.

[0062] Fig.17 A flow chart of an exemplary method for use with the method 200 is shown in accordance with an exemplary embodiment. At block 212 , the method 200 includes coupling each of the plurality of floor covering panels 102 to the plurality of attachment mounts 108 .

[0063] Fig.18 A flow chart is shown of an exemplary method for use with the method 200 in accordance with an exemplary embodiment. At block 214, the method 200 includes positioning a plurality of slats 114 on each of the plurality of floor covering panels 102 in a staggered configuration.

[0064] Figure 15-18 The exemplary process shown in the flowchart in may be manually implemented or performed by a system integrator, a third party, and / or an operator (eg, a customer). Figure 15-18 The exemplary process shown in the flow chart in enables reduced installation time of floor panels, increased reliability and repeatability of installation, and increased durability of the floor covering system 100 due to less installation materials required. Figure 15-18 The exemplary process shown in the flowchart in also enables improved aesthetics and customer satisfaction. Figure 15-18 The exemplary process shown in the flow chart in enables individual floor covering panels to be replaced as needed.

[0065] Installation of the floor covering system 100 in a commercial airliner, such as in a galley area, enables a custom aesthetically pleasing floor covering as compared to the use of conventional floor mats. Furthermore, the examples described herein are able to avoid the problem of floor covering buckling because the plurality of floor covering panels 102 are allowed to move laterally as an integral unit, such as the plurality of floor covering panels 102 all moving together. Thus, the individual floor covering panels in the floor covering system 100 described herein will not telegraph, buckle or blister because the plurality of attachment mounts 108 will allow for lateral movement while ensuring that the plurality of floor covering panels 102 do not lift when an upward load is applied. Thus, the floor covering system 100 provides a floating floor system that is held vertically in place but allows for lateral movement in a limited manner, and the floor covering system 100 accommodates the technical challenges of movement of the aircraft's subfloor that occurs during flight.

[0066] In an example, preventing relative movement between the plurality of floor covering panels 102 also allows for the use of softer non-stick sealants in the gaps, thereby allowing for easier replacement of individual floor panels.

[0067] In addition, in an example, a single floor panel can be replaced when damaged or defective. For example, because the floor panel can be moved, a non-permanent softer non-stick sealant can be used, allowing easy replacement. The plurality of edge panels 112 are removable, so that any panel in the plurality of floor covering panels 102 can also be replaced.

[0068] Unless explicitly stated, the terms "first", "second", etc. used herein are used only as labels and are not intended to impose the order, position, and logical hierarchy requirements of the items mentioned by these terms. Moreover, for example, referring to a "second" item does not require or exclude the existence of, for example, a "first" or lower numbered item and / or, for example, a "third" or higher numbered item.

[0069] By the terms "substantially" and / or "approximately", it is meant that the characteristic, parameter or value referred to need not be achieved exactly, but rather deviations or variations (including, for example, tolerances, measurement errors, measurement precision limitations and other factors known to those skilled in the art) may be achieved in an amount that does not preclude the effect that the characteristic is intended to provide.

[0070] Different examples of a (multiple) system, a (multiple) device, and a (multiple) method disclosed herein include various components, features, and functions. It should be understood that various examples of a (multiple) system, a (multiple) device, and a (multiple) method described herein may include any of the components, features, and functions of any of the other examples of a (multiple) system, a (multiple) device, and a (multiple) method disclosed herein, and all of these may be intended to be within the scope of the present disclosure.

[0071] Descriptions of different advantageous configurations have been presented for purposes of illustration and description, but are not intended to be exhaustive or to be limited to examples of the form disclosed herein. Many improvements and variations will be apparent to those skilled in the art. In addition, different advantageous examples may describe different advantages compared to other advantageous examples. One or more examples are selected and described to best explain the principles of the examples, practical applications, and to enable others skilled in the art to understand the present disclosure for various examples with various modifications suitable for contemplated specific uses.
