Description

BACKGROUND OF THE INVENTION

[0001] 1. Claim of Priority

[0002] The present application is a continuation-in-part application of previously filed, now pending application having Ser. No. 09/415,145, filed on Oct. 8, 1999.

FIELD OF THE INVENTION

[0003] The present invention is directed towards a load supporting assembly which may include a pallet assembly primarily, but not exclusively, designed to retain and support cargo within the interior of commercial aircraft or other carrier and including a track assembly designed to removably secure a retaining cover or like retaining assembly to the pallet, wherein the retaining assembly is of the type typically used in maintaining cargo on a pallet during transport thereof. The track assembly may be replaced in whole or in part by a plurality of attachment members secured to a base panel for secure attachment of one or more side panels in a manner which eliminates the need for conventional fasteners, such as rivets or the like, commonly used in the manufacture of pallets and/or like load supporting assemblies, thereby minimizing pallet down time due to fastener repair requirements of the Federal Aviation Association (FAA).

[0004] 1. Description of the Related Art

[0005] During recent years, there has been a significantly large increase in the amount of freight or cargo transported by commercial airlines. While it has long been common practice to include the transport of freight on airlines, which are primarily directed to passenger service, there has been a significant increase, in the airline industry, of companies dedicated entirely to the transport of freight as versus passengers. A major contributing factor to this increase in the transport of air freight is the proliferation of air freight services which are directed to the express delivery of packages of all sizes, throughout the United States and overseas. Such express delivery services are offered not only by the U.S. Postal Service but by private companies. All of the larger delivery companies, of the type set forth above and of standard commercial cargo, maintain an entire fleet of commercial aircraft, wherein the individual airplanes have their interior configurations structurally modified to facilitate carrying the maximum freight or cargo load possible.

[0006] The loading of air freight within the cargo compartment of an aircraft typically involves the use of pallets, available in a variety of different sizes, which are disposed in the aircraft and are otherwise designed to support and retain cargo thereon. A primary benefit to the use of such pallets is the ability to load a large volume of smaller items at one time, after they have been pre-loaded on the pallet at a remote location. Moreover, the pallet functions to maintain the items securely and uniformly retained on the aircraft. In particular, the supported load is typically maintained in its intended position on the pallet by means of some type of retaining cover or structure, specifically designed to allow the maximum load to be placed on each pallet, while at the same time assuring that the loaded cargo will not shift or be inadvertently displaced from the pallet during take-offs, landings or during the actual in-flight maneuvers of the aircraft.

[0007] It is of course widely known that the “balancing” of any load carried by aircraft, whether the load is comprised of a plurality of passengers, freight or a combination of both, is of primary importance for the safe and efficient operation of the aircraft. Any inadvertent shifting of the load or other significant re-distribution of weight within the aircraft, during flight, such as would be the result of inadvertent displacement of cargo or freight from its supported position on a pallet, could result in dangerous, unsafe flight conditions and threaten the safety of the aircraft, as well as the life of the flight personnel and/or passengers.

[0008] In order to avoid any inadvertent displacement of air cargo or freight, of the type set forth above, the aforementioned retainer structures or covers overlying the freight are removably but securely connected to the pallet base, in a manner which would normally prevent such displacement. Pallet structures of known or conventional design typically include a track, extending along at least a portion of the periphery thereof, which is specifically structured to securely fasten the retaining covers in their intended, overlying position, relative to the load or freight mounted on the pallet base. Due to the importance of eliminating any possibility of weight shift due to inadvertent displacement of freight or cargo within the interior of an aircraft, regulatory agencies, such as the FAA, regularly and thoroughly examine the structural integrity of the pallet structures used to support and retain freight loads within an aircraft, as set forth above. One problem consistently found during such examinations is the failure of a significant number of pallet assemblies because the aforementioned retaining tracks have a tendency to become at least partially separated from the base of the pallet. Conventional or known pallet design and construction normally involves the use of closely spaced rivets or other applicable fasteners extending along the length of the track assembly and serving to securely anchor the track assembly to the base of the pallet. The aforementioned regular inspections all to often determine that the rivets become loosened or displaced, because of the tremendous stress or force placed thereon by the attached retaining covers, during normal flight conditions. Moreover, the requirements of the regulatory agencies are so strict, that even if only a small number of fasteners fail, the entire pallet must be made inactive until repaired.

[0009] Therefore, there is a recognized need for a significant improvement in the design and structure of a pallet assembly designed to support and retain heavy loads of freight or cargo in a stable manner on the interior of aircraft or other vehicles. Such an improved pallet assembly should be structured to eliminate, as much as possible, the inadvertent and/or partial detachment of a track assembly from the base of the pallet, preferably by eliminating the use of a plurality of rivets, or like fasteners, that are independently susceptible to failure, to fixedly attach the assembly to the base. In addition, such an improved pallet assembly should be designed to facilitate the assembly and manufacture of the various components associated with the pallet assembly, in a manner which will prevent separation or partial detachment of the track assembly from the base of the pallet, and which increases the security and stability of the pallet within the FAA requirements.

SUMMARY OF THE INVENTION

[0010] The present invention is directed towards a pallet assembly or other load supporting assembly of the type primarily, but not exclusively, designed to support and retain various loads within the interior of a common carrier such as a commercial aircraft. Moreover, the pallet assembly maintains those loads in a manner which facilitates the removable but secure attachment of a load retaining cover or like structure in overlying relation to the freight mounted on the base of the pallet.

[0011] The load retaining structure may include a variety of different known or conventional designs, and is in and of itself not an intended part of the present invention. However, the purpose of securing the load retaining structure to the pallet assembly, regardless of the structural design thereof, is of prime importance in preventing the shifting and/or displacement of the load, supported on the pallet, within the aircraft, or other vehicle, during flight or travel.

[0012] More specifically, the pallet assembly of the present invention comprises a base, including a central portion, formed preferably, but not necessarily, of a solid sheet of high strength, light weight material, such as but not necessarily limited to metal. Further, the base includes a peripheral portion disposed in surrounding relation to the central portion, wherein the peripheral portion preferably, but not necessarily, comprises a multi-sided configuration. The peripheral portion comprises a plurality of peripheral flanges, each having an elongated configuration and extending along the length of the various sides of the peripheral portion. Each of the peripheral flanges comprises a predetermined dimension and cross-sectional configuration, which is cooperatively structured with a track assembly for attachment there between, as will be explained in greater detail hereinafter.

[0013] The track assembly is preferably connected to and extends about the peripheral portion of the base and is structured to removably receive and fixedly secure any of a variety of different load retaining structures in covering, protective relation to the load mounted on the base of the pallet assembly.

[0014] Each of the peripheral flanges terminates at oppositely disposed ends, substantially corresponding to the ends of the sides of the base on which they are mounted. Accordingly, correspondingly position ends of adjacent peripheral flanges are disposed in spaced relation to one another, in the vicinity of the corresponding corner of the base. In order to avoid such corner spaces and provide a substantially continuous periphery extending about the base, the pallet assembly of the present invention also comprises a plurality of corner assemblies. Each corner assembly is disposed in aligned relation to a different one of the plurality of corners of the base and is interconnected to the base through direct attachment to correspondingly positioned portions of the track assembly, as also will be described in greater detail hereinafter.

[0015] The aforementioned track assembly preferably comprises a plurality of integral and/or segmented track segments, preferably equal in number to the plurality of peripheral flanges secured to the base and also preferably being substantially equal in length to the respective ones of the peripheral flanges to which they are attached. Each of the track segments, may also be formed of a light weight, high strength, metallic or other applicable material.

[0016] As set forth above, each of the track segments are cooperatively structured to be fixedly and securely mounted on respective ones of the peripheral flanges, in a manner which will eliminate the necessity of utilizing a plurality of conventional fastener or connector members, such as rivets, screws, bolts or the like, that are typically employed with conventional or known pallet assemblies of the type designed to support and retain air cargo or freight. More specifically, each of the track segments preferably includes a securement assembly, such as a track, defined at least along a majority of the length of said track segment and preferably along the entire length thereof. Each track is preferably disposed in communicating relation with an outer exposed surface or face of the track segment and is specifically structured to removably receive and securely retain cooperatively structured coupling elements mounted and/or associated with the aforementioned load retaining structures.

[0017] In addition, each of the track segments preferably includes and elongated slot formed at least partially on the interior thereof, and including an opening extending along a length thereof. The elongated slot is cooperatively structured with each of the peripheral flanges, such that the peripheral flange may be inserted into the slot at least partially on the interior of the track segment. A portion of the peripheral flange is allowed to pass through the aforementioned opening so as to not interfere with the integral or otherwise fixed junction between the peripheral flange and the base. Accordingly, it should be apparent that the cross-sectional configuration of the each of the peripheral flanges may substantially correspond to the cross-sectional configuration of each of the elongated slots. By virtue of these corresponding configurations, at least a portion of the peripheral flange can be inserted within and fixedly retained by a corresponding track segment so as to define a gripping, at least partially surrounded or enclosed attachment of the track segment with a corresponding one of the peripheral flanges.

[0018] As set forth above, each of the aforementioned corner assemblies are interconnected to the base by means of their attachment to adjacently positioned ones of the plurality of track segments. Accordingly, each of the corner assemblies includes a corner segment disposed in aligned relation to a corresponding corner of the base, and two connector assemblies, each extending outwardly from spaced apart portions of the corner segment into aligned relation with the adjacently positioned track segments. In order to accommodate attachment of the corner assemblies to the corresponding track segments, again without the need for the utilization of conventional fasteners or connectors, such as rivets or the like, the connector assemblies associated with each corner assembly are preferably received within open ended channels, which at least partially define a hollow interior portion of the respective track segments. Moreover, those open ended channels are preferably communicatively and/or integrally defined with the elongated slot wherein the peripheral flange is disposed.

[0019] It is also emphasized that while the predetermined cross-section of each of the peripheral flanges may be defined by a general L-shape configuration, the cross-sectional configuration of each of the peripheral flanges, as well as the elongated slot integrally formed in the track segments, may vary from an L-shape, and still be capable of defining a secure, gripping attachment between corresponding ones of the peripheral flanges and track segments.

[0020] By way of example, another embodiment of the present invention is primarily directed to a load supporting assembly and includes a base panel having a plurality of outwardly extending peripheral flanges, generally similar to the base of the pallet assembly embodiment, as described above. However the peripheral flanges of the base panel are characterized by a more continuous, at least partially curvilinear cross-sectional configuration which corresponds to the cross-sectional configuration of the elongated slot within the track assembly. Alternatively, one or more attachment members may be utilized instead of the track assembly. The one or more attachment members each include at least a first elongated slot extending along the length thereof. The first slot includes a cross-sectional configuration substantially corresponding to that of the “curvilinear” cross-sectional configuration of the peripheral flange of the base panel, as set forth above. By virtue of these cooperative cross-sectional configurations, the peripheral flanges of the base panel, and in certain other embodiments a number of other side panels or auxiliary panels, may be disposed in substantially enclosed relation within correspondingly disposed elongated slots formed in the various attachment members, as will be explained in greater detail hereinafter. A gripping engagement will thereby be defined between the peripheral flanges of the base panel and the respective attachment members as well as any peripheral flanges associated with the side panels or auxiliary panels and correspondingly disposed in interconnecting relation with the attachment members. Again, as set forth above, the use of conventional connectors such as rivets and the like, will thereby be eliminated.

[0021] Accordingly, alternative embodiments of the present invention comprise a base panel connected to one or more side panels and possibly one or more auxiliary panels so as to substantially define an enclosure or container. Such a load supporting assembly, including the aforementioned enclosure or container, may or may not include at least one track assembly for the connection of a load retaining structure thereto, in the manner set forth above with regard to the embodiments comprising the pallet assembly. Also, one or more side panels may be connected to the base panel and to one another using a plurality of the aforementioned attachment members.

[0022] The attachment members include spaced apart first and second elongated slots having corresponding cross-sectional configurations with the peripheral flanges associated with both the base panel and the aforementioned side panels. Moreover, at least one but preferably all or a majority of the attachment members include a support segment integrally formed as a part thereof and serving to interconnect opposite longitudinal sides of the various attachment members in which the first and second slots are formed. The support segment may assume anyone of a plurality of different configurations in order to orient the interconnected base panels and side panels in a substantially transverse relation to one another. More specifically, an attached side panel may be oriented relative to the base panel in a substantially perpendicular relation thereto or in an angular, substantially outboard orientation relative thereto. The relative orientations of the interconnected base panels and side panels are at least partially dependent, on the overall intended or predetermined configuration of the enclosure or container assembly defining the load supporting assembly of this embodiment of the present invention. It is emphasized that the terminology “corresponding cross-sectional configuration”, when referring to an interconnection between the elongated slots in the attachment members and the peripheral flanges is not meant to limit these respective structures to include precisely equivalent cross-sectional configurations. To the contrary, this term is meant to be generally descriptive of components with cross-sectional configurations cooperatively structured to be sufficiently similar to accomplish the aforementioned secure, enclosed, gripping engagement, which eliminates the need for conventional fasteners, such as rivets, typically used in the construction and assembly of a pallet or like load supporting assembly. It should also be noted that the overall shape and size of the load supporting container is also dependent on the type of commercial carrier, such as a commercial airline, on which the load supporting container of the present invention is intended to be loaded.

[0023] These and other features of the present invention will become more clear when the drawings as well as the detailed description are taken into consideration.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0045] As shown in the accompanying Figures, the present invention is directed towards a load supporting assembly, which in at least one embodiment comprises a pallet assembly, generally indicated as 10. The pallet assembly 10 is of the type that is capable of supporting and retaining a load, in the form of freight, cargo, etc., and more particularly, is preferably configured to be securely disposed within the interior cargo compartment of an aircraft.

[0046] More specifically, the pallet assembly 10 comprises a base, generally indicated as 12. The base 12 preferably, but not necessarily, includes a central portion 14 formed from a solid, one piece construction, and preferably of a metallic sheet material. Additionally, the peripheral portion of the base 12 comprises at least one but preferably a plurality of peripheral flanges, generally indicated as 16, disposed in spaced apart relation from one another about the peripheral portion of the base 12. Each of the peripheral flanges 16 preferably includes an elongated configuration, and extends along the length of a corresponding one of a plurality of sides of the base 12, which normally, but not necessarily comprises, a multi-sided configuration. Furthermore, although each of the peripheral flanges 16 may be of unitary or segmented construction, the overall length of each peripheral flanges 16 is preferably substantially equivalent to the length of the side of the central portion 14 of the base 12 along which it extends. Accordingly, each of the peripheral flanges 16 preferably terminates in oppositely disposed ends 18, and because the length of each of the peripheral flanges 16 is substantially equivalent to the respective sides to which it is attached, there is a space between correspondingly positioned ends 18 of adjacently positioned peripheral flanges 16 as best shown in FIGS. 2 and 3. The space between the correspondingly positioned ends 18 is disposed in aligned relation with a corner 20 of the base 12, and in some cases may be greater if a shorter peripheral flange structure is desired.

[0047] As will be explained in greater detail hereinafter, the open space disposed in aligned relation with the base corner 20 is filled by a corner assembly, generally indicated as 22, and shown in detailed in FIGS. 6 through 9. Further, as also best shown in FIGS. 2 and 3, each of the peripheral flanges 16 are preferably integrally or otherwise fixedly secured to the central portion 14 along respective ones of the sides 14′. The structuring of the central portion 14 and the plurality of flanges in the manner described facilitates assurance of the structural integrity of the pallet assembly 10, as well as a secure mounting or interconnection of the remaining components of the pallet assembly 10, when assembled without the need for fasteners. Additionally, in order to further add to the strength and/or structural integrity of the base 12 and particularly the central portion 14 of base 12, one or more seams or breaks 15 may be formed in the central portion 14, as shown in FIG. 3. Depending on the overall configuration of the base 12, the seam or break 15 may have a generally transversely intersecting or other appropriate configuration.

[0048] A further structural feature of the present invention is the provision of a track assembly, generally indicated as 24, securely attached to the base 12, generally about the peripheral portions thereof. In particular, the track assembly 24 is secured, in at least partially surrounding relation to the central portion 14 of the base 12, in a substantially fixed manner which eliminates the need for the utilization of conventional fasteners or connectors, such as but not limited to rivets, typically used in known or conventional pallet structures. Of course, if desired, additional fasteners could be added for increased strength.

[0049] More specifically, the track assembly 24 comprises at least one, but preferably a plurality of track segments 26 shown in mounted or assembled form on the pallet assembly 10 in FIG. 1 and shown in detail in FIGS. 4 and 5. Each of the one or more track segments 26 comprises an elongated configuration, preferably corresponding in length to the peripheral flange 16 to which it is attached. Much like the peripheral flanges 16, the track segments 26 may be of integral or segmented construction. Further, each of the track segments 26 preferably comprises an at least partially hollow interior portion. In particular, each track segment 26 preferably includes at least one channel 28 which may extend partially or completely along a length of the track segment 26. However, in at least one preferred embodiment shown in FIG. 5, each track segment 26 includes two channels 28 and 28′. Further, each channel 28 and 28′ preferably include an open end which corresponds to and extends through the end 30 of the respective track segments 26. As a result of these channels 28 and 28′, an overall weight of the track segments 26 is reduced. In addition to the one or more channels 28 and 28′, the aforementioned hollow interior portion of the individual track segments 26 may also be defined by a track, generally indicated as 32. The track 32 is preferably, but not necessarily, a single continuous structure, and includes a track interior 34 which communicates directly with a plurality of spaced apart apertures 36, as best shown in FIG. 4. Each of the apertures 36 are separated by a narrowed portion 38 having a lesser transverse dimension than the diameter or equivalent transverse dimension of the plurality of apertures 36. The track 32 is structured, dimensioned and configured to accommodate the removable but fixed retention of a connector or other structure schematically represented as 37 (FIG. 9) secured to and/or associated with a load retaining structure, such as a net, (not shown for purposes of clarity). As set forth above, such a retaining structure is maintained in a covering, retaining relation to any load supported on the base 12 in the conventional fashion. As can be appreciated, the apertures 36 and/or other structure to which the load retaining structure is secured, may include a variety of different configurations and may be defined only at fixed securement points rather than as a continuous elongate structure. Still, however, the track interior 34 which defines each portion or all of the track 32 fastening points also preferably extends through the end 30 of the track segment 26, as in FIG. 5. Moreover, it is also preferred that the track interior be generally recessed, preferably a greater extent than that available with conventional pallets, so as to provide more secure retention therebeneath.

[0050] The track segments 26 of the present invention also include an elongated slot 40 defined therein and preferably extending along a length of each of the track segments 26. The overall length of the slot 40, which may be continuous or segmented, is preferably at least generally equal to the length of the individual peripheral flange 16 which is attached thereto, as explained hereinafter. The slot 40 also includes an opening, as at 42, which also preferably extends along the entire length of the slot 40.

[0051] With reference to both FIGS. 3 and 5, the peripheral flanges 16 have a predetermined cross-sectional configuration which fits into and preferably corresponds with the cross-sectional configuration of the slot 40. In the embodiment of FIG. 3, such cross-sectional configuration is defined by flange segment 17 extending laterally outward from the central portion 14 of base 12, and a flange segment 19, which integrally or otherwise fixedly interconnects the flange segment 17 to one of the respective sides 14′ of the base 12. While the specific cross-sectional configuration of each of the peripheral flanges 16 may vary, one preferred cross-sectional configuration is substantially an “L-shape” so as to define a generally “Z-shape” configuration with the central portion 14 of the base 12. Similarly, the cross-sectional configuration of the elongated slot 40 also has what may be considered an at least partially corresponding cross-sectional configuration by virtue of the relative position of the slot 40 and its associated opening 42, as well as the body of each of the track segments 26 surrounding the slot 40. Therefore, in order to assure and define a secured, gripping attachment between each of the track segments 26 and the corresponding ones of peripheral flanges 16, the flange segment 17 is inserted into the interior of the elongated slot 40 such that the flange segment 19 of each of the peripheral flanges 16 protrudes outwardly from the opening 42. Each of the peripheral flanges 16 are thereby attached in secured gripping engagement and in somewhat surrounded or enclosed relation on the interior of the slot 40, while allowing a portion of each of the peripheral flanges 16 to extend outwardly through the opening 42 associated with each of the elongated slots 40. By virtue of this secured, gripping attachment, the use of a plurality of conventional fasteners or connectors, such as but not limited to rivets, bolts, and screws, is thereby avoided and the chances of even partial separation or detachment of the track segments 26 from their fixedly secured, operative position about the peripheral portion is minimized. Furthermore, the securement is continuous along the entire length of the peripheral segments so as to achieve a uniform engagement throughout. It is emphasized that the slot 40 may extend through one or both opposite ends or extremities of the track segments 26 so as to facilitate the sliding engagement between corresponding ones of the track segment 26 and the peripheral flange 16.

[0052] Another feature of the present invention as shown in FIG. 6 through 9 and comprises the aforementioned corner assembly 22. In practice, a plurality of corner assemblies 22 are preferably incorporated within the pallet assembly 10 of the present invention, depended upon the overall configuration thereof Each of such corner assemblies 22 includes a corner segment 46 which is dimensioned and configured to substantially fill the space between correspondingly positioned ends 18 of adjacently positioned ones of the peripheral flanges 16, as best shown in FIG. 2 and 3. The inclusion of one or more corner assemblies 22 in the manner shown in FIG. 1 provides a substantially continuous, un-interrupted peripheral portion that eliminates the aforementioned spaces between the corresponding ends 18.

[0053] More specifically, each of the corner assemblies 22 includes at least one but preferably two, outwardly extending connecting assemblies, generally indicated as 48. Each connecting assembly 48 preferably includes a plurality of connector members comprising a first connector member 50 and a second connector member 52. As best shown in FIGS. 6, 7, and 8, each of the connecting assemblies 48 extends outwardly from spaced apart ends 46′ of the corner segment 46. In addition, the individual connector members 50 and 52 are preferably disposed in spaced apart relation to one another and extend outwardly from a common end 46′ of the corner segment 46 in the same direction and in substantially parallel relation to one another. As is also apparent, the relative dimensions of the individual connector members 50 and 52 of each connecting assembly 48 are oppositely oriented but otherwise substantially correspond to one another both in transverse dimension and length. Also, the cross-sectional configuration of each of the connector members 50 and 52, as well as the dimensions thereof are specifically designed to be inserted respectively in the open ends of the channels 28 and 28′ and an open end of the track 32, as seen in FIG. 9. Accordingly the cross-sectional configuration and overall dimension of the channels 28 and 28′ is such as to receive by insertion, connecting members 50 and 52 respectively. As set forth above, the interior of the track 32 is structured to receive a conventional connector or attachment structure 37.

[0054] It should be apparent therefore that the mounting or securement of each of the corner assemblies 48 in aligned relation to corresponding base corners 20 is achieved by direct connection to adjacently positioned track segments 26, without the use of rivets or like conventional connectors. Of course, it is understood that one or more of the connector members could be integrated as part of a single or separate element to correspond to an opening into the hollow interior of the track segments. For example, separate channels and the like may be defined in the ends of the track segments for the express purpose of receiving one or more connector members 50 and 52 having substantially the same or a variety of different configurations. Also, a tight, press-fit engagement could be achieved with or without a locking structure, such as a raised button disposed thereon.

[0055] The present invention also comprises additional embodiments in the form of a load supporting assembly which may include a cargo or load supporting container or enclosure. More specifically, and with primary reference to FIGS. 10 through 18, the load supporting assembly of the present invention includes a base panel, generally indicated as 60, having at least one but preferably a plurality of peripheral flanges 62 collectively disposed in substantially surrounding relation to a central portion 64 and integrally secured thereto so as to extend laterally outward from corresponding sides of the central portion 64 in the manner disclosed in FIGS. 11 through 14. More specifically, each of the peripheral flanges 62 may include either a more distinct, multi-sided cross-sectional configuration or the substantially curvilinear cross-sectional configuration as shown in the embodiment of FIG. 3. It should be further noted that the one or more peripheral flanges 62 not only extend laterally outward, as demonstrated in FIGS. 10 and 11, but also are disposed in a raised or transversely outward position from the central portion 64. The cross sectional configuration and outward displacement of the peripheral flanges 62 in this manner facilitates the connection of one or more attachment members thereto, as will be explained in greater detail hereinafter, in a manner which eliminates the need or use of conventional connectors such as rivets or the like.

[0056] With reference to the embodiment of FIG. 12, the base panel 60 may be used as a pallet assembly of the type discussed with reference to the embodiments of FIGS. 1 through 9. In the embodiment of FIG. 12 the peripheral flanges 62 are secured to one or more track assemblies generally indicated as 66. Also, when such track assembly 66 are connected to the base panel 60, in the manner set forth in FIG. 12, a plurality of appropriately structured, dimensioned and configured corner assemblies, generally indicated as 22 in the embodiments of FIGS. 6 and 7, may be mounted in the appropriate spaces 67.

[0057] With reference to FIGS. 13 and 14, additional preferred embodiments of the present invention comprise the base panel 60 having at least one, but preferably a plurality, of its peripheral flanges 62 secured to one or more first attachment members generally indicated as 70. Each of the first attachment members 70 preferably includes an elongated configuration which substantially corresponds to the length of the peripheral flange 62 to which it is connected. In addition, the various embodiments of the attachment member 70 include a first elongated slot 72 and a second elongated slot 74 disposed in spaced apart relation to one another and interconnected by a support segment 76. The support segment 76 is integrally formed as part of the first attachment member 70 and, as will be explained in greater detail hereinafter, may take a variety of different configurations. Both the first and second slot 72 and 74 extend along substantially the entire length of the attachment member 70 and each include an opening 78 and 79 respectively, which is dimensioned and configured to allow passage there through of a peripheral flange 62 or equivalent structure, as will also be explained in greater detail hereinafter. The elongated first slot 72 has a cross-sectional configuration, which substantially corresponds to the cross-sectional configuration of the peripheral flange 62 or other structure with which it is connected. Similarly, the opening 78 associated with the elongated slot 72 is dimensioned to receive the peripheral flange therein in the manner clearly shown in FIGS. 13 and 14. By virtue of the cooperative dimensioning of the respective cross-sectional configurations between the first slot 72 and the peripheral flange 62, an enclosed, substantially gripping engagement is accomplished between attachment member 70 and the base panel 60. This gripping engagement eliminates the need for any type of conventional connector, such as a rivet or like structure, commonly associated with the production and assembly of pallet structures or load supporting assemblies.

[0058] The second slot 74 of the attachment member 70 is designed to receive and grippingly engage a peripheral flange or like longitudinal edge structure 81 of a side panel or other structural component 80. In an embodiment which may utilize both the base panel 60 and the side panel 80, the load supporting assembly of the present invention may be more specifically defined as a load supporting container or enclosure which may be structurally configured to facilitate loading on a commercial carrier, such as a commercial airline or the like. The side panel 80 may be somewhat similarly structured to the base panel 60 by virtue of it including at least one and preferably a plurality of peripheral flanges 82 as well as a central portion (not shown in detail for purposes of clarity).

[0059] With reference to FIGS. 13 and 14, it is emphasized that the one or more first attachment members 70 may be structured such that the support segment 76 or 76′ may take a variety of different orientations or configurations. Accordingly, the side panel 80 may be oriented in a variety of predetermined positions relative to the base panel 60 dependent, at least in part, on the preferred or predetermined overall shape or configuration of the container or enclosure defining the load supporting assembly of the present invention. The overall configuration of the load supporting container assembly may be dependent upon the type of the common carrier, such as a commercial aircraft, in which the container is loaded.

[0060] Accordingly, the difference in the orientation or configuration of the support segment 76′ from that of the support segment 76 is for the express purpose of orienting the side panel 80 in a preferred position relative to the base panel 60, or other side panels 80, so as to accomplish the preferred structural configuration of the container or enclosure which defines the loads supporting assembly of the present invention. Naturally, the support segment 76, 76′ may have other preferred configurations so as to orient anyone or more side panels 80 in other preferred or predetermined positions to accomplish the overall desired configuration of a load supporting container or enclosure, as set forth above. An example of this is disclosed in FIG. 13, wherein the first attachment member 70 disposes the side panel 80 in a substantially perpendicular relation to the base panel 60 and the second attachment member 70′ orients the side panel 80 in a somewhat “outboard” or outwardly extending angular orientation as shown.

[0061] Again with reference to FIG. 14, the plurality of different attachment members may also include an auxiliary attachment member, generally indicated as 70″. The auxiliary attachment member 70″ includes the first elongated slot 72 having opening 78 for the receipt and gripping, enclosed engagement of the corresponding peripheral flange 62 of the base panel 60, as shown. However, the support segment 76″ has a configuration which disposes the opposite end of the auxiliary attachment member 70″ in an “inboard”, substantially overlying relation to the peripheral flange 62 to which it is attached and in somewhat overlying relation to a corresponding side of the central portion 64 of the side panel 60. In addition, it should be noted that the auxiliary attachment member 70′ may include the provision of a track 32′ for the attachment of a load retaining structure thereto. Accordingly, the track 32′ is structurally and functionally similar to the track 32 as shown in the embodiments of FIGS. 4 and 5, as set forth above.

[0062] Another preferred embodiment of the load supporting assembly of the present invention also includes at least one but preferably a plurality of second attachment members generally indicated as 86 and distinguishable from one another by the designation 86, 86′ and 86″ as shown in FIGS. 15 through 17. More specifically, each of the one or more second attachment members 86, 86′, 86″ includes a support segment 88, 88′ and 88″ configured to dispose a first and second slot 92 and 94 in spaced relation to one another and at different relative positions or orientations. Each of the second attachment members 86, 86′, 86″ has an elongated configuration and the respective first and second slots 92 and 94 extend substantially along the length thereof. Further, each of the first slots 92 is disposed and structured to enclose and grippingly engage a peripheral flange or correspondingly positioned peripheral edge of either a side panel 80 or a third panel 95. The third panel 95 may or may not be structured similar to the base panel 60 and side panel 80 by including a central portion (not shown) and one or more peripheral flanges or edges 96. Each of the peripheral edges 96 may have a cross-sectional configuration which either corresponds to the cross-sectional configuration of the corresponding slot 92 or 94 in which it is mounted or is otherwise cooperatively structured to accomplish the aforementioned enclosed, attached, gripping engagement therewith. Therefore, the third panel 95 may serve as a cover or “roof” or as a panel segment disposed in any preferred or intended location so as to accomplish the overall structural configuration of the load bearing container or enclosure, which defines at least one embodiment of the load supporting assembly of the present invention, as explained above.

[0063] With reference to the specific embodiments of FIGS. 15, 16, and 17, the second attachment member 86 has its first and second slots 92 and 94 respectively oriented so as to position a side panel 80 in substantially transverse or more specifically perpendicular relation to the third panel 95, as well as an associated base panel 60, which may be interconnected thereto. In the embodiment of FIG. 16, the second attachment member 86′ is configured to dispose the side panel 80 in an outboard or outwardly extending, angular orientation relative to the third or roof panel 95. In the embodiment of FIG. 17, the second attachment member 86′ is demonstrated as interconnecting two third panels 95 which may or may not be disposed as roof or cover panel segments and wherein the third panels 95 are disposed in generally parallel or co-planar relation to one another.

[0064] Another structural feature of the present invention comprises at least one of the first or the second elongated slots 74, 92, and/or 94 of each of the embodiments of the attachment members 70, 70′, 70″, 86, 86′ 86″, etc. having a preferred cross-sectional configuration as shown in FIG. 18. More specifically, the cross-sectional configuration of the elongated slot, generally indicated as 100, comprises at least two bearing surfaces 102 and 104 disposed in substantially transverse relation to one another. More specifically, at least one of the bearing surfaces 104 assumes an angular orientation relative to the other of the bearing surface 102 and even more specifically the bearing surfaces may collectively define a generally triangular configuration. Accordingly, the cross-sectional configuration 100 of the elongated slot of FIG. 18 which, as set forth above, may be incorporated in one or all of the elongated slots 74, 92, and/or 94 of the various attachment members, includes the bearing surfaces 102 and 104 being relatively oriented so as to at least partially enclose and securely grip and engage a correspondingly disposed peripheral flange of one of the side panels 80 and/or third panels 94. As schematically demonstrated in FIG. 18A through 18G the configuration 100 also increases the versatility of the overall assembly by allowing any of a variety of different configurations of the peripheral flanges to be secure therein. As set forth above, such a secure gripping engagement between respective ones of the panels and attachment members eliminates the need of conventional connectors, such as rivets or the like, commonly used in pallet assembly and construction.

[0065] Since many modifications, variations and changes in detail can be made to the described preferred embodiment of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.

[0066] Now that the invention has been described,
