    REFERENCE TO PENDING REQUEST
    [01] This application claims the benefit of Provisional Patent Application Serial No. US 61/752,512, filed January 15, 2013, which is incorporated herein by reference in its entirety. TECHNICAL FIELD
    [02] The present invention relates generally to molded reservoirs, and more particularly to the couplings between molded reservoirs and supporting structures. FUNDAMENTALS
    [03] Some containers or reservoirs may contain flammable liquids and materials. For example, fuel tanks carry fuel to vehicle fuel systems, such as automotive fuel systems. The fuel is finally supplied to a main engine like an internal combustion engine. In addition to carrying fuel, fuel tanks commonly house components within their interiors, such as pumps, valves, and the like. SUMMARY
    [04] In at least some implementations, a molded reservoir support frame coupling may include an anchor and a support frame. The anchor is carried by the molded reservoir and has a side wall with at least a first flange which projects generally laterally from the side wall. The support structure is formed separately from the anchor and has at least one second flange which projects generally laterally therefrom and adapted to be overlapped by the first flange to inhibit longitudinal separation of the anchor and the support structure. In at least some implementations, the support structure may be provided in a position where the flanges do not overlap and are then moved to a position where they overlap. This can be achieved, for example, by relative rotation between the support structure and the anchor.
    [05] In at least some implementations, a fuel tank may include a fuel tank wall at least partially defining an interior for containing fuel and having at least one first flange on the interior that projects generally laterally from a first portion of the fuel tank. fuel tank wall. The fuel tank wall may have at least one second flange on the inside which projects generally laterally from a second portion of the fuel tank wall. A support structure may join the first and second fuel tank wall portions and has a first end with at least a third flange which projects generally laterally, and a second end with at least a fourth flange which projects generally laterally. Together, the first flange and the third flange are laterally and longitudinally overlapped, and the second flange and the fourth flange are laterally and longitudinally overlapped to inhibit disconnection of the support structure from the fuel tank wall.
    [06] The molded reservoir support frame coupling may include an anchor and a support frame. The anchor may have one or more first flanges which may project generally laterally from a side wall of the anchor. The support structure may have one or more second flanges which may project generally laterally therefrom. To interconnect the anchor and the support structure, the anchor and support structure can be brought together in a longitudinal direction and an end of the one or more second flanges can advance beyond an end of the one or more first flanges. In addition, the anchor, the support structure, or both can be rotated and the one or more first flanges and the one or more second flanges can bend over each other and surface-to-surface confrontation between the flanges can inhibit longitudinal separation. of the anchor and the support structure.
    [07] A fuel tank may include a fuel tank wall and support structure. The fuel tank wall may partially or more define an interior to contain fuel, and may have one or more first flanges and one or more second flanges. The one or more first flanges may project generally laterally from a first portion of the fuel tank wall. The one or more second flanges may project generally laterally from a second portion of the fuel tank wall. The one or more first flanges may have a first top surface, and the one or more second flanges may have a second top surface. The support structure may join the first portion and the second portion of the fuel tank wall. The support structure may have a first end and a second end. The first end may have one or more third flanges which may project generally laterally at or near the first end, and the second end may have one or more fourth flanges which may project generally laterally at or near the second end. The one or more third flanges may have a first bottom surface, and the one or more fourth flanges may have a second bottom surface. To interconnect the fuel tank wall and the supporting structure, the one or more first flanges and the one or more third flanges may be brought together longitudinally adjacent to each other, and the one or more second flanges and the one or more fourth flanges may be brought together longitudinally adjacent to each other. The fuel tank wall, the support structure, or both can be rotated and the first top surface of the one or more first flanges can be brought to face the first bottom surface of the one or more third flanges, and the second top surface of the one or more second flanges may be brought to face the second bottom surface of the one or more fourth flanges. And the clash of the respective top and bottom surfaces can inhibit the disconnection of the fuel tank wall and supporting structure.
    [08] A fuel tank may include a fuel tank wall and support structure. The fuel tank wall may partially or more define an interior to contain fuel. The fuel tank wall may have an anchor with a side wall. The fuel tank wall may have one or more first flanges which may project generally laterally from the side wall. And the fuel tank wall may have one or more gaps located in the side wall and adjacent to the one or more first flanges. The support structure can be constructed to join the fuel tank wall. The support structure may have one or more second flanges which may project generally laterally therefrom. The one or more first flanges, the one or more second flanges, or both, may have a raised portion. And the one or more first flanges, the one or more second flanges, or both, which is free of and does not have the raised portion, may have a segmented annular portion. To interconnect the fuel tank wall and the support structure, the support structure can be inserted into the anchor and the one or more second flanges can be passed through the one or more gaps. The fuel tank wall, the support structure, or both can be rotated and the one or more first flanges and the one or more second flanges can bend over one another. BRIEF DESCRIPTION OF THE DRAWINGS

    [22] Referring in more detail to the drawings, a support frame coupling 10 can be used in a molded reservoir such as a vehicle fuel tank 12 as a low pressure automotive fuel tank that is part of a system of automotive fuel. The support structure coupling 10 provides an effective mechanical interlock between the fuel tank 12 and a support structure 14 that joins one or more walls of the fuel tank. As will be described in greater detail below, anchors of the support structure coupling 10 can be formed in a wall 16 of the fuel tank 12 during an associated molding process that forms the fuel tank, and the support structure 14 can be subsequently attached to the anchor once the molding process is complete. Although it has been described in the context of an automotive fuel and tank system, the support frame coupling 10 can be fitted and used in other applications such as in boat applications, recreational vehicle applications, as well as others. As an aside, the terms axial, radial and circumferential as used herein refer to directions with respect to the generally circular and cylindrical shapes of the respective components of the support frame coupling 10, such that axially refers to a direction along an axis. of the components, radially refers to a direction along a radius of the components, and circumferentially refers to a direction along a circumference of the components, these terms also apply even if the components of the support structure coupling do not are generally circular and cylindrical in shape, as they need not be.
    [23] Referring to Figure 1, the fuel tank 12 has one or more walls 16 and a body defining an interior 20 in which liquid fuel is held. Wall 16 includes a top wall portion 22, a bottom wall portion 24, and a side wall portion 26 extending between the top and bottom wall portions. In other embodiments not shown in the figures, the shape and geometry of the fuel tank 12 may be more complex than those shown in Figure 1, and may include staggered top and bottom wall portions and different interior compartments. As will be known to those skilled in the art, the fuel tank 12 may be composed of a multilayer plastic material such as a high density polyethylene (HDPE) layer, an ethylene vinyl alcohol (EVOH) layer, adhesive layers, or other and different layers, or it may be composed of a single layer of material. The fuel tank 12 can be manufactured by a blow molding process or by some other process.
    [24] Still referring to Figure 1, the support structure 14 extends between and contacts one or more of the fuel tank wall portions 12 in order to join the wall portions together and ultimately reinforce structural integrity. of the fuel tank wall 16. In this embodiment, the support structure 14 joins the top and bottom wall portions 22, 24. And although not shown, the support structure 14 can carry components housed within 20 of the fuel tank. fuel 12 including valves, a fuel gauge, or other components. In the embodiment of Figure 1, the support structure 14 is in the form of a pole or beam, but may take other shapes, including columns, crossbars, or internal baffles. The beam has a beam body 28, a first or top end 30, and a second or bottom end 32.
    [25] The support structure coupling 10 can have different designs, constructions and components depending on - among other considerations - the design and construction of the fuel tank 12 and the design and construction of the support structure 14. In the embodiment of the figures, the support structure coupling 10 includes parts of the support structure 14 and parts of the fuel tank wall 16. The first and second ends 30, 32 of the support structure 14 are part of the support structure coupling 10, as well as a first anchor 34 and a second anchor 36 of the fuel tank wall 16.
    [26] The first and second ends 30, 32 may be a unitary and one-piece extension of the beam body 28, or they may be a discrete component attached to the beam body via a mechanical connection, a force fit, crimping by heat, melting, or other fixing technique. The first and second ends 30, 32 may have different designs and constructions depending on, among other considerations, the design and construction of the first and second anchors 34, 36. In the embodiment of Figures 6-12, the first and second ends 30, 32 have each a closed top wall 40 and a side wall 42 extending from the top wall. In other embodiments, the top wall does not need to be closed and can instead be open or otherwise constructed. The ends 30, 32 may have a generally annular and cylindrical shape, and may be composed of a glass fiber reinforced plastic material such as an HDPE, other plastic material, or a metal material.
    [27] For interconnection with the first and second anchors 34, 36, each of the first and second ends 30, 32 may have one or more connection characteristics. In the embodiment shown, the connection features comprise a first flange 44, a second flange 46, and a third flange 48. In other embodiments not shown, a single flange or more or less than three flanges could be provided. As shown in Figures 6-12, flanges 44, 46, 48 are spaced apart by openings 50 located around the generally circumferential periphery of sidewall 42. Flanges 44, 46, 48 project laterally (in this example, radially outward) from the top wall 40, and in one direction are radial extensions of the top wall in this embodiment. In other embodiments, the flanges need not project from the top wall and instead can project from the side wall axially spaced from the top wall, or they can project from both the top and side walls. As used herein, the terms laterally and laterally refer to directions that are generally orthogonal to a direction in which ends 30, 32 and anchors 34, 36 are initially brought together prior to rotation, as described in more detail below. . In the example of Figure 3, the lateral direction is indicated by the arrow L1, in this case, the lateral direction also becomes the radial direction. In addition, flanges 44, 46, 48 project laterally beyond side wall 42, and they project longitudinally (in this example, axially outwards) above top wall 40. As used herein, the terms longitudinally and longitudinally refer to in directions that are generally parallel to the direction in which the ends 30, 32 and the anchors 34, 36 are initially brought together prior to rotation, as described in greater detail below. In the example of Figure 3, the longitudinal direction is indicated by the arrow L2, in this case, the longitudinal direction also becomes the axial direction.
    [28] Still referring to Figures 6-12, each individual flange 44, 46, 48 has a top surface 51 and a bottom surface 53 (shown in Figures 8 and 9, respectively). Each flange 44, 46, 48 may also have a connecting web or shank 52 extending from the side wall 42 to the top wall 40, and may have a tab 54 extending from the shank. As best shown in the sectional profile of Figure 12, the shank 52 is a thin-walled section of the respective flange, while the tab 54 has a generally circular cross-sectional profile. Below each of the flanges 44, 46 and 48 - and between the side wall 42, the shank 52, and the tab 54 - a recess or groove 60 can be defined. Groove 60 may be generally circumferentially coextensive with the thin wall section of each of flanges 44, 46, 48.
    [29] In addition, each individual flange 44, 46, 48 has a raised or longitudinally inclined portion in the form of a helically extending portion 62, and has a non-raising circumferentially extending portion 64. In other embodiments, the inclined portion may be provided in another form such as a staggered portion or a curved portion. The helically extending portion 62 facilitates initial interconnection with the complementary parts of the first and second anchors 34, 36, and generally traces a segmented helix. Portion 62 provides a lifting or ramping action that can initially pull the support structure and anchor together after rotation. In Figures 6-12, the portion 62 is shown in a first or flexed state in which the rod 52 is not stressed and is at rest, and the portion is generally in a position to receive a complementary feature from the anchors when they are initially brought into position. set. After complete interconnection between the supporting frame ends 30, 32 and the anchors 34, 36, the portion 62 is urged into a second or flexed state in which the portion is bent around the rod 52 and moved in the longitudinal direction to a non-elevated position substantially in line with portion 64 and top wall 40. In this embodiment, rod 52 only yields to urge, but does not break or fracture when bent to the second state. Furthermore, as best shown in Figures 10 and 11, an apex of portion 62 constitutes a leading end 66 thereof. And a trailing end 68 - shortened longitudinally with respect to the leading end - expands into the circumferentially extending portion 64.
    [30] The circumferentially extending portion 64, in contrast to the helically extending portion 62, traces a circumference of the sidewall 42, without otherwise deflecting in the longitudinal direction. Also, unlike portion 62, circumferentially extending portion 64 extends from side wall 42 through a thicker extent than shank 52 and does not substantially bend during interconnection. Although shown as unitary with each other, portions 62, 64 may be separated from one another by apertures in other embodiments. And in still other embodiments not shown in the figures, the support structure need not have interconnecting structures at both ends, and may instead have interconnecting structures such as flanges at one end, with the other end having another structure intended to simply support against the fuel tank wall, support against another component, or simply remain suspended inside the fuel tank.
    [31] Referring now to Figures 2-5, the first and second anchors 34, 36 are formed as a one-piece unitary portions of the fuel tank wall 16. Here, the first anchor 34 is located in the wall portion 22, and the second anchor 36 is located in the bottom wall portion 24. The first and second anchors 34, 36 may have different designs and constructions depending on, among other considerations, the design and construction of the first and second ends 30, 32. In the embodiment of Figures 3-5, each of the first and second anchors 34, 36 includes a first depression 70 and a second depression 72 formed in the fuel tank wall 16. In other embodiments not shown in the figures, a pair of depressions it need not be used for the anchors, and instead simply a single depression could be used. The first and second depressions 70, 72 are generally circular and are concentric with respect to each other, with the first depression located laterally outside the second depression, and the second depression, in turn, located laterally within the first depression. . Referring in particular to Figure 5, the first depression 70 protrudes longitudinally inwards when viewed from the interior 20 of the fuel tank 12. And conversely, the second depression 72 protrudes longitudinally outwards when viewed from the inside. from the outside of the fuel tank 12. Here, the terms inward and outward are used with respect to the interior 20, whereby inward refers to the inward direction and outward refers to a direction away from the interior. By their shape, the first and second depressions 70, 72 form a first side wall 76 and a second side wall 78.
    [32] For interconnection with the first and second ends 30, 32, the second depression 72 of each of the first and second anchors 34, 36 may have one or more connecting features. In the embodiment shown, the connection features comprise a first flange 80, a second flange 82, and a third flange 84. In other embodiments not shown, a single flange or more or less than three flanges may be provided, which may or may not depend on the number of flanges provided for the interconnect support structure. In this embodiment, the flanges 80, 82, 84 are in the form of lugs, and therefore will be referred to later as lugs. Still referring to Figures 3-5, the lugs 80, 82, 84 are spaced apart by means of gaps 86 located generally around the circumferential periphery of the second side wall 78. The lugs 80, 82, 84 project laterally (in this (e.g. radially inwardly as well) from the second side wall 78. Further, the shoulders 80, 82, 84 are spaced longitudinally inwardly from an inner surface 88 of the fuel tank wall 16 and the second depression 72 , and define grooves 90 therebetween. Each individual shoulder 80, 82, 84 has a top surface 92 and a bottom surface 94 (top and bottom are not necessarily with reference to the figures). Each shoulder 80, 82, 84 has a segmented annular shape and generally traces a circumference of the second side wall 78 from a first circumferential end 96 to a second circumferential end 98, without otherwise deflecting in the longitudinal and axial direction. In other embodiments not shown in the figures, the shoulders could be longitudinally inclined.
    [33] As mentioned, the first and second anchors 34, 36, and thus the lugs 80, 82, 84, can be formed during a molding process of the fuel tank 12. In one example, the lugs 80 , 82, 84 may be formed in the fuel tank wall 16 by a molding process that is modified but still somewhat similar to the blow molding process described in Patent Application Publication No. US 2011/0140314 entitled Arrangement Assembly and assigned to TI Automotive Technology Center GmbH. Here, in the modification, three tool arms (also called sliders), - one for each of the three lugs - are advanced and working ends of these engage a wall material. of fuel tank still partially molten and malleable (in this embodiment, the wall material is that of the second side wall 78). The pliable wall material is laterally displaced inwardly to form the segmented annular shapes of the shoulders 80, 82, 84. The internally displaced wall material is allowed to cool and harden, and the working ends of the tool arms are retracted, leaving the finally formed shoulders 80, 82, 84. The first and second depressions 70, 72 may also be formed during the molding process of the fuel tank 12. In one example, the depressions 70, 72 may be formed by means of a surface of forming in the form of complementarity of a blow molding mold.
    [34] To interconnect the fuel tank 12 and the support structure 14, the support structure is inserted into one of the anchors and the two are twisted together so that their connecting features are interlocked together and hold the structure together. support and fuel tank together. Initially, the ends 30, 32 can be brought adjacent to respective anchors 34, 36. This process can be carried out after the molding process of the fuel tank 12 is complete and with no further processes involved. While the more involved processes may be suitable and even preferable in some cases, they may involve molding a reservoir around a support structure assembly in the midst of the accompanying blow molding process, or it may involve separating cut halves of a reservoir. and place them around a set of support structure. The support structure assembly 10 as described herein, in contrast, may only utilize an opening in an already molded fuel tank 12 for inserting the support structure 14 and for inserting one or more of the ends 30, 32 with one or more more of the anchors 34, 36.
    [35] Taking an end and an anchor for exemplary purposes, the first end 30 is advanced longitudinally toward the first anchor 34 to insert the first end into the first anchor. Before or during its advancement, the first end 30 is rotated to a first position in which the leading end 66 of each flange 44, 46, 48 is circumferentially and angularly aligned with a corresponding clearance 86 of the first anchor 34. As longitudinal advancement proceeds, leading ends 66 pass through gaps 86 between circumferential ends 96, 98 of neighboring shoulders. The top surfaces 51 of the flanges 44, 46, 48, and particularly of the helically extending portion 62, may clash closely with or even contact the inner surface 88 of the first anchor 34 as the first end 30 is fully advanced into the first anchor. The helically extending portion 62 is in its first and flexed state at this point in the interconnect.
    [36] From the first position, one or both of the fuel tank 12 and the support structure 14 can be circumferentially rotated and flipped to a second position in order to interconnect and interlock the fuel tank and support structure against disconnection. and longitudinal separation. In the second position, the flanges 44, 46, 48 radially overlap the shoulders 80, 82, 84 so that the top surface 51 of the portions 62, 64 closely confronts or contacts the inner surface 88, and the bottom surface. 53 of portions 62, 64 intimately confront or make contact with the top surface 92. The helically extending portions 62 are moved into the grooves 90 and, as turning continues, the helically extending portions are urged to their second and abutting flexed state. against the inner surface 88 of the fuel tank wall 6. The circumferentially extending portions 64 are therefore also moved into the grooves 90 and secured between the shoulders 80, 82, 84 and the fuel tank wall 16 as the 62 portions are in the second state. Flanges 44, 46, 48 and lugs 80, 82, 84 can be joined to the second position in a somewhat tight, force-fitting fashion to help hold them together without too much play between the support structure 14 and the fuel tank 12. In the second position, and with the portions 62 in their second, flexed state, the portions 62 exert a force against the inner surface 88 of the fuel tank wall 16 and thus help to maintain a taut state in the fuel tank. support frame coupling 10. Once fully in the second position, as shown in Figure 2, the bottom surfaces 53 of the flanges 44, 46, 48 can confront and make contact with the top surfaces 92 of the terminals 80, 82, 84 - this engagement and contact can be between the helically extending portions 62 and the terminals, and between the circumferentially extending portions 64 and the shoulders. Confrontation and contact inhibit and prevent disconnection of fuel tank 12 and support structure 14.
    [37] In other embodiments not shown in the figures, the support structure coupling 10 may have different designs, constructions, and components. For example, the flanges of the support structure may have a segmented annular shape without a raised portion, while the shoulders of the anchors may have a raised portion in the form of a helically extending portion. In another example, the flanges of both the support structure and the anchors may have helically extending portions. In yet another example, the flanges of the support structure can project laterally and radially inward, while the shoulders of the anchors can project laterally and radially outward, in this example the ends of the support structure would have a female construction (as opposed to the male in the embodiment of the figures), and the anchors can be projected from a depression that is formed in the longitudinally inward direction.
    [38] While the forms of the invention described herein are presently preferred embodiments, many others are possible. It is not intended here to mention all possible equivalent forms or branches of the invention. It is understood that the terms herein are merely descriptive and not limiting, and changes may be made without departing from the scope of the invention.
