Description:
TECHNICAL FIELD 
     The invention relates to a separate winding or rolling accessory device for installing, removing and storing a cover of a vehicle. The invention also relates to the method of using the device. 
     BACKGROUND 
     A cover, such as a tonneau cover, can be positioned to cover a truck or vehicle bed. When the truck bed is needed to transport a large load, the cover can be removed from the bed. Typically, the cover can be removed by folding or sliding the cover from the truck or vehicle bed. The cover can follow tracks, railings, support walls or other extra members to guide or secure a tonneau cover to the truck bed or vehicle enclosure. 
     SUMMARY 
     In general, a winding and rolling device or assembly includes a shaft configured to attach to a perimeter attachment member of a tonneau cover along a narrow dimension of the tonneau cover. The shaft can be adjustable in length and can attach to, and move with, a cover of a vehicle. The device can be utilized to attach, wind, install, remove and store the cover, and be used to rewind and reinstall the cover, after which the device can be separated from the cover and stored. 
     In one aspect, the device includes an adjustable and releasably attachable tonneau winder accessory for use in flowing and suspended interaction with a pickup truck or vehicle tonneau cover having one or more perimeter attachment members, and in complimentary interaction with a selected portion of the perimeter attachment member; for winding, rewinding, supporting, guiding or positioning the tonneau cover, while remaining positioned therewithin. The accessory interacts with and positionally relates to, a pickup truck or walled vehicle bed or storage area. The adjustable and attachable accessory tonneau winder can be provided with a telescopically extensible base assembly having a central portion and at least one slidably communicating subassembly member. The central portion and the at least one slidably communicating subassembly member can be provided as having a lengthwise outer surfacing, and having and defining along the lengthwise outer surfacing at least one respective coupling attachment members for engaging and connecting to a vehicle tonneau cover. The base assembly, and those parts that contain it, can be positionally adjustable and releasably coupleable to a number of preselected perimeter coupling locations which can include the perimeter attachment member of the vehicle tonneau cover. 
     In another aspect, an accessory floating tonneau winding and guiding device for use in interaction and engagement with a vehicle tonneau cover. 
     The tonneau cover, with which the device can be used with, can include at least two end perimeters, each of which, in conventional use, can be provided with a plurality or number of coupling members. In certain embodiments, the device can be utilized in interaction and engagement with a number of such coupling members along one of the end perimeters of the cover, depending on the use of the device being selected by the user. The device can be used, for example, for supporting, positioning, and/or placement of the tonneau cover in relation to a walled vehicle storage or bed area. 
     In another aspect, the accessory floating tonneau winding and guiding device can be provided with a base support member having first and second ends and a lengthwise laterally walled portion therebetween. The device also can be provided with a middle coupling member, being fixedly secured to the lengthwise laterally walled portion, at a positional orientation which is generally equidistant in relation to the first and second ends. The lengthwise laterally walled portion defines a first positioning channel generally proximate in positional orientation to the first end of the base support member, and a second positioning channel which is generally proximate in positional orientation to the second end of the base end. 
     In another aspect, the device can be provided with a first positionable coupling member, which is slidably and securely installed in the first positioning channel, and a second positionable coupling member, which is slidably and securely installed in the second positioning channel. 
     In another aspect, a floating tonneau cover guiding and supporting device for use in interaction with a tonneau cover having a number of coupling members, and in interaction with a plurality of such corresponding, respective, coupling members on a perimeter of a tonneau cover, for securing, rolling, guiding, positioning and storing the tonneau cover in relation to a walled vehicle storage or bed area with which the tonneau cover guiding and supporting device also interacts. The tonneau cover guiding and supporting device includes a first base member having first and second ends and a lengthwise laterally walled portion, and has attachment members for biasably and releasably securing a further member to each of the first and second ends. The device also includes a middle coupling member, which is fixedly secured to the lengthwise laterally walled portion of the first base member at a positional orientation which is generally equidistant in relation to the first and second ends of the first base member and a second base member having first and second ends and a lengthwise laterally walled portion, with the first end thereof having members responsive to the attachment member of the first base member for biasably and releasably attaching the second base member to the first base member. A coupling member can be fixedly secured to the lengthwise laterally walled portion of the second base member at a general positional orientation which is proximate to the second end of the second base member. The device also can include a third base member having first and second ends and a lengthwise laterally walled portion, where the first end thereof has members responsive to the attachment members of the first base member for biasably and releasably attaching the third base member to the first base member. A coupling member can be fixedly attached to the lengthwise laterally walled portion of the third base member at a general positional orientation which is proximate to the second end of the third base member. The first end of the second base member can be slidably and biasably attached to the first end of the first base member, and the first end of the third base member is slidably and biasably attached to the second end of the first base member, so that the middle coupling member of the first base member, the coupling member of the second base member and the coupling member of the third base member are each in general axial alignment with one another. 
     Advantageously, the winding and rolling tonneau device is of simple construction, preferably of one to three main core components, acting as one individual accessory unit, and serving to engage and interact with a vehicle tonneau cover, to accomplish several functional uses with regard to installing, removing, positioning and storing the cover. 
     In addition, the tonneau cover winder with one or more stationary attachment coupling members, and one or more positionable coupling members make the winding unit, complimentary and responsive to a number of the types of coupling members (for example, various snap and complimentary male-female oriented members) utilized on a number of tonneau covers, as well as the different or variable sizes or dimensions of tonneau covers. 
     It is also productive and worthwhile to provide the tonneau winding and rolling device as a portable, self-contained unit, which is user-friendly and easy to manually operate, for the purpose of attaching this unit to a tonneau cover of a vehicle, and winding, rewinding, positioning and storing the device, both with, and without the tonneau cover attached thereto, in relation to a walled, hidden or sunken truck or vehicle bed or storage area, or to store then arrangement (winder or winder coupled to tonneau cover) in a separate location apart from a vehicle. 
     The unitary accessory tonneau cover attachment winder can float, flow, or be suspensionable or can be suspended as it moves with the winding or turning action, carrying the tonneau cover with it while being moved to a preselected location. It is also desirable that, after providing movement to a selected location in relation to a vehicle bed or storage area, the winder be detachable and removable from the tonneau cover, if desired, or stored with or without the tonneau cover at a desired location. 
     The movable tonneau roller or winder which is installable and can be placed in an axial and lengthwise orientation, across a walled truck bed or like enclosure, and can be positioned more easily between a fore and aft location of the vehicle enclosure. 
     In addition, the tonneau cover winder and roller can be capable of rolling, and unrolling, a tonneau cover while positioning an end portion or end perimeter of the cover for attachment at a desired location, such as at the end wall of a vehicle bed or near the front wall or cab area of a pickup truck. The device can also be capable of depending on the weight of the tonneau cover itself for stationary positioning when the cover is partially or completely rolled up in relation to the front or back of a truck bed enclosure. 
     The tonneau cover winder as an accessory unitary device can not use or depend on a spring loaded or biasing members to engage or move a tonneau cover, can not utilize separate or additional tracks, railings, support walls or other extra members to guide or secure a tonneau cover, other than a pre-existing and provided truck bed or vehicle enclosure, to guide and secure the cover, and can not utilize a separate stationary housing and/or support for enclosing and spooling or rolling-up the cover, and limiting the storage location options for the cover. 
     Other features and advantages of the invention will be apparent from the description and drawings, and from the claims.

     DETAILED DESCRIPTION 
     Referring now to the drawings, FIGS. 1 through 8, there is shown an accessory tonneau attachment  10 , referred to herein as the “tonneau accessory”  10 , or “accessory”  10 . 
     The tonneau accessory  10  is utilized, in preferred embodiments, in interaction with a tonneau cover (not shown; see, for example, FIG. 35) having at least two end perimeters, where, as is often the case in provided tonneau covers, the cover has at least two end perimeters which each have a multiple number of snap, coupling or other attachment members, located thereon, for securing the cover to a vehicle, such as a pickup truck, walled rear bed area. It will also be understood that many such covers provide at least four perimeters, the front, back, and right and left sides, with the attachment members for securement to a vehicle bed or compartment. The tonneau accessory  10  of the present invention, is therefore, intended to engage and interact with two such perimeters of a tonneau cover for the purpose and use of supporting, positioning and placing the cover in relation to a walled vehicle bed or storage area and/or a walled area and an overhanging beam or rib support which is often utilized in securing such covers in pickup truck beds. 
     The tonneau accessory  10  is provided with the base support  12  which has the first end  14 , the second end  16  and the lengthwise lateral wall  18 . The middle coupling member  20  is attached and secured to the lengthwise lateral wall  18 , in the middle portion of the wall  18 , between the first and second ends  14  and  16 . The lateral wall  18  is provided with the first positioning channel  22  at, near or proximal to the first end  14 ; and the second positioning channel  24  at or proximal to the second end  16 . The first positionable coupling  26  can be attached within the channel  22  so that it may slide and position within the channel  22 , for utilization in adapting to positional differences or dimensional idiosyncracies of a particular tonneau cover. In like manner, the second positionable coupling  28  is slidably and positionably installed within the channel  24 . 
     The base support  12  and other base support members to be discussed later herein, are preferably constructed or fabricated, configurationally, as a hollow, or partially hollow or in-tunneled, cylindrical tubing member or tubal element; as shown by example in the figures. Additionally, materials for fabrication would include various types of polymer tubing or various metal or light metal alloy materials; as well as wood, polymer wood or fiber glass combinations. 
     The accessory  10  can also include the end members  30  and  32  which are attached to the respective ends  14  and  16 ; as optional members and elements to improve durability of the accessory. Additionally, in preferred embodiments, the positioning channels  22  and  24  are fabricated in general axial alignment with one another, and in general alignment with the middle coupling member  20 , as illustrated, by example, in the figures. 
     As indicated above, in part, many of the available tonneau covers provided for use have included as a part of their construction, various positioned coupling or attachment members or members. These members consist of various types of snap members or elements, or male-female structured complimentary coupling orientations, hook and loop (e.g., VELCRO®) fastening components and/or locations, or other or similarly constructed coupling or attachment members. Therefore, the examples utilized in the various figures attached hereto illustrate a reciprocal or corresponding type of snap coupling member in that it is, presently, frequently utilized. However, it will be understood that many types of coupling and/or attachment members and members can be used, and that this diverse use of different types of coupling and attachment members are incorporated herein. The accessory  10  can use these members to be releasably attached to a given tonneau cover for positioning and storing, as discussed herein. 
     The tonneau cover, or like covering or protective sheet, can be attached integrally to the tonneau accessory  10 , such as through attached tonneau flap portions or portions of the tonneau sown, spliced, securely combined or otherwise attached integrally, fixedly or permanently to the accessory  10  of the present invention, so that the accessory  10  can be utilized in combination with a tonneau cover or in substantially, permanently or securely fixed interaction with the cover, so that the accessory  10  travels with and is always utilized in non-releasable attachment with the tonneau cover or like cover or sheet in its use in storage, installation and removal (or non-installation) of the cover in its positional relation to a truck bed, vehicle storage area or like interactional or installation environment. The accessory can be, for example, installed by the user or the cover manufacturer, or the accessory can be configured to fit in a pocket built into the tonneau cover. 
     Also, in preferred embodiments, as illustrated by example, the additional coupling  34  can be attached to the base support  12  at a positional location generally equidistant or between the first end  14  and the middle coupling  20 , and each are fabricated to be positioned in general axial alignment with one another. In like manner, the additional coupling  36  is attached to the base  12  at a positional location generally between the second end  16  and the middle coupling  20 . It will be understood that is well within the scope and spirit of the present invention to place additional coupling members in other locations along the base  12 , and to attach such respective coupling members as fixed members such as the middle coupling member  20 ; or within a channel or other configuration for releasable movement and positioning therein, as is the case with regard to the first and second positionable couplings  26  and  28  in relation to the first and second positioning channels  22  and  24 , respectively. 
     Referring now to FIGS. 9 through 16B and FIGS. 20 through 28, the tonneau accessory  10  can be a tonneau cover guiding and supporting device for use in interaction and working engagement with a tonneau cover (not shown) having a multiple number or plurality of snaps, attachments, hook and loop attachments, or other coupling members, and in interaction with a corresponding respective group or number of such coupling members on an end, side or other positionally placed or positionally available perimeter or axis of a tonneau cover. The accessory  10 , in this embodiment, is also utilized, interactionally or interactively, for securing, rolling, guiding, positioning and storing the tonneau cover in relation to a walled vehicle storage or bed surface area such as those provided within (or part and parcel of) a pickup truck, station wagon or like vehicle, with which the accessory  10  also interacts. 
     The accessory  10  in this embodiment is provided with the first base member  40  which has the first and second ends, respectively,  42  and  44 ; and the lengthwise laterally walled portion  46 . The middle coupling  48  is securely (or securedly) fixed and attached to the lengthwise laterally walled portion  46  at a location and position generally equidistant, or between the two, in relation to the first and second ends  42  and  44  of the first base member  40 , as illustrated by example, and can also be attached at other locations between the ends  42  and  44 . 
     The accessory  10  is further provided with the second base member  50  which has its first and second ends, respectively,  52  and  54 ; and its lengthwise laterally walled portion  56 . The coupling member  58  is securely fixed or fixedly attached to the lengthwise laterally walled portion  56  at a location or position which is on, adjacent or close to (proximate to) the end  54  of the second base member  50 . Also provided is the third base member having the first and second ends, respectively,  62  and  64 , and the lengthwise laterally walled portion  66 . The coupling member  68  is securely attached to the walled portion  68  of the third base member  60  at a general location or position proximate or close to the end  64  of the base member  60 . The couplings  48 ,  58  and  68  (as well as the chamber coupling members  48   c ,  58   c  and  68   c , later described herein) can be pivotally or positionally installed as described earlier herein. 
     The end  52  of the second base member  50  slides into the first end  42  of the first base member 40 . The end  62  of the third base member  60  slides into the second end  44  of the first base member  40 . In this manner, the middle coupling member  48  of the first base member  40 , the coupling member  58  of the second base member  50  and the coupling member  68  of the third base member  60  are, each placed in general axial position and alignment with each other, where each of them is oriented in axial line (or alignment), one with the other; as illustrated, by example in FIGS. 9,  10 ,  11 ,  14 ,  15 ,  21 ,  22 ,  24 ,  25 ,  26 ,  21 A,  21 B,  27 ,  28  and other figure illustrations herein. Other positional orientations can result and be utilized during installation of multiple connecting or extensible base members. Optionally, set screws or pins  49   a ,  49   b ,  49   c  and  49   d  can be present to hold base members in position (see FIG.  9 A). 
     The first end  42  of the first base member  40  defines and has an installation channel  42   h , and the second end  44  has and defines the installation channel  44   h . The first end  52  of the second base member  50  is appropriately and accordingly dimensioned so that it will slide and fit within the installation channel  42   h  of the first end  42  of the first base member  40 . And in like manner, the end  62  of the third base member  60  is dimensioned to slidably fit with the installation channel  44   h  of the second end  44  of the first base member  40 . 
     In preferred embodiments, the first base member  40  is provided with an attachment member as a part of structure for securing a further structural member to each of the first and second ends  42  and  44  so that these members are biased as they are inserted, and remain stiffly resilient as the accessory  10  is being utilized, while also being releasable from within the respective ends  42  and  44 . In corresponding manner the second base member  50  is provided with structural members which are responsive to the attachment members of the first base member  40 , for biasable, resilient and detachable or releasable attachment and coupling of the second base member  50  to the first base  40 ; and in like manner, the third base member  60  is provided with structural members which are responsive to the attachment members of the first base member  40 , for similar biasable and detachable coupling of the third base members  60  to the first base  40 . 
     With regard to the attachment members of the first base  40 , in preferred embodiments, the first end  42  of the first base  40  is provided with the dimple projection member  72  which structurally extends from the lengthwise laterally walled portion  46  into the installation channel  42   h ; and the second end  44  of the first base  40  is provided with the dimple projection  74  which extends from the lengthwise laterally walled portion  46  into the installation channel  44   h.    
     With regard to the structural members of the second base  50  which are responsive to the attachment members of the first base member  40 , for biasable, resilient and detachable or releasable attachment and coupling of the second base member  50  to the first base  40 ; the lengthwise laterally walled portion  56  is provided with the first projection channel  76 . The channel  76  is generally transverse (or positionally set or oriented approximately at 90 degrees) in relation to the axial alignment or position of the coupling member  58  of the end  54 . In like manner, with regard to the members of the third base  60  which are responsive to the attachment members of the first base  40 , for biasable and releasable attachment of the third base  60  to the first base  40 ; the laterally walled portion  66  is provided with the first projection channel  78 , being generally transverse in position to the position and alignment of the coupling member  68 . 
     In further related preferred embodiments, the laterally walled portion  56  at or near the end  52  of the second base  50  is provided with the second projection channel  79 , generally positioned transversely in relation to the general axial alignment of the coupling member  58  at or near the end  54 , and across and opposite from the first projection channel  76 , as illustrated, by example. This constitutes, in these related embodiments, further elements of construction of the members of the second base  50  responsive to the attachment members of the first base member  40  for biasably and releasably attaching the second base  50  to the first base  40 . In like manner, the laterally walled portion  66  at or near the end  62  of the third base  60  is provided with the second projection channel  80  which is, also, generally positioned transversely in relation to the general axial alignment of the coupling member  68  at or near the end  64 , and across and opposite from the first projection channel  78 , thus forming further elements of the members of the third base  60 . As shown in FIGS. 12B-12D, base  50  can have a variety of cross-sections, provided that the cross-section complements the adjoining bases. The cross-sections can include a tongue and groove arrangement or a “c” shaped arrangement. 
     Additionally, in further related embodiments of the tonneau accessory  10 , the attachment members of the first base member  40  further includes a structure where the lengthwise laterally walled portion  46  at or near the first end  42  of the first base  40  is further provided with the projection rail member  81  which extends within the installation channel  42   h  of the first end  42 , and is placed in a position which is opposite and spaced in relation to, and across from, the dimple projection member  72  of the first end  42 ; as illustrated by example. In like manner, the laterally walled portion  46  at or near the second end  44  of the first base  40  is further provided with the rail projection member  82  which extends within the installation channel  44   h  of the second end  44  and is placed in a position which is opposite, spaced and adjacent and across from the dimple projection member  74 . 
     In preferred embodiments of the accessory  10 , the installation channel  42   h  and the installation channel  44   h , as illustrated, by example, are connected, one with the other, and are coextensive and concurrent with one another. Also, the middle coupling member  48  of the first base  40 , the coupling member  58  of the second base  50  and the coupling member  68  of the third base  60 ; are each, respectively, fabricated, constructed and provided as male, female or corresponding or complimentary snap components, and are designed, in this respect, to correspond to such snap members being utilized on a number of vehicle tonneau covers. It will, however, be understood, as earlier indicated, in part, that it is well within the scope and spirit of the present invention to provide other diverse types of attachment and coupling members and members to correspond with or otherwise engage and interact with a given tonneau cover in attaching the accessory  10  to it. In this regard, a further example, without limitation, and preferred embodiment of the present invention is shown in FIGS. 23 through 28 with respect to the channeled snap chamber coupling members  48   c ,  58   c  and  68   c . It is also possible to attach or connect such coupling components or elements to the various base members described, in many secure and fixed ways, or to provide such coupling members as an integral part of the respective base member that each is attached to or a part of. For example, as shown in FIG. 24A, base  46  can have three holes  48 b positioned to contain snaps (not shown) in a base having the cross-section of FIG.  12 C. The holes can be located in a flattened region of the curves surface. The opposite side of the base  46  of FIG. 24A shown in FIG. 24B has channeled snap chamber coupling members  48   c . When two coupling members are present on the base, a single base can couple to different existing tonneau cover fittings. The drawing and illustration Figures show, by example, and by setting forth exemplar parts, that such coupling members can be attached by utilizing a nut (n) (designated in the following drawing illustration numbering by adding “n” to the element number) and bolt (b) (designated in the following drawing illustration numbering by adding “b” to the element number) arrangement; such as is illustrated by example in FIGS. 1 through 8 at elements  26 ,  28 ,  26 B,  26   n ,  28   b  and  28   n.    
     Other means may be used for the fixed or positional attachment of coupling members. It is also within the scope and spirit of the invention, as discussed in part above, to provide more than one coupling attachment member to each of the base members  40 ,  50  and  60 ; and to provide pivotable or positional attachment members, or different types of such members on the same base member. 
     Reference is made to the drawing figure illustrations of FIGS. 1 through 28 and the photographic illustrations of FIGS. 29 through 35 e , showing examples of preferred embodiments of the invention. The scope and spirit of the present invention and tonneau accessory  10 , in preferred embodiments, sets forth a tonneau bridge rod device having a rod assembly for use in movable interaction with a pickup truck or vehicle tonneau cover installation having available locations for perimeter or other positional attachment; for winding, rolling, guiding, supporting or positioning the tonneau cover in relation to and interaction with a pickup truck/vehicle bed having walls and/or available overhanging support rib/beam members (as shown in the illustrations). Preferred embodiments of the rod assembly can be provided having ported first and second ends and lengthwise laterally walled portions, as illustrated in the drawing and photographic Figures by example. A number of coupling members are attached to the laterally walled portions of the rod assembly; and the accessory  10  is provided with members defined and supported by its rod assembly for varying the positional relationships of the coupling members as they relate to each other. This is shown by example in FIGS. 1 through 8 and  29  through  35   e  with regard to the first positioning channels  22  and  24 , respectively, and the first and second positionable couplings  26  and  28 , respectively. It is also illustrated by example in FIGS. 9 through 16B and  20  through  28 , with regard to the variable positioning movement of the base members  40 ,  50  and  60 , and their respective coupling members  48 ,  58  and  68  (and  48   c ,  58   c  and  68   c ) in the various preferred embodiments shown by example. 
     Additionally, as illustrated in FIGS. 17 through 19, the first and second base members  90  and  92 , respectively, and the first and second coupling members  94  and  96  can be provided with the first base member  92  having ported end  98  for releasable and biasable receipt and installation of the second base  92 , as similarly described above and illustrated by example. 
     In this manner, one or more of the coupling members utilized in the present invention in association with one another can be, optionally, positionally adjusted to readily accommodate and couple with one or more corresponding perimeter coupling locations on a vehicle tonneau cover with which the Tonneau Accessory  10  interacts; and to position and store the tonneau cover in relation to a walled or overhang rib installed vehicle bed storage area (as illustrated by example in FIGS. 29 through 35 e ). 
     In a series of related embodiments, the accessory  10  is provided as an adjustable and releasably attachable tonneau winder for use in flowing and suspended interaction (in that it flows with and is partially suspended by the tonneau cover with which it is attached and with which it moves in interaction with the movement of a tonneau cover, as illustrated, by example, in the photographic FIGS. 29 through 35 e ). The accessory  10  interacts with a pickup truck or vehicle tonneau cover or similar cover, or any covering sheet having installed on any of its perimeters or axes some type of attachment, coupling or cooperating male-female-oriented snap or connection members. The accessory  10  responds in installable use, in complimentary interaction, therefore, with a selected portion of the perimeter or axis attachment members on the tonneau cover or like cover; for winding, rewinding, supporting, guiding and/or positioning the tonneau or cover, while remaining positioned within the tonneau or cover. The accessory  10  also responds in further interaction with, and positional relation to, a pickup truck or walled vehicle bed or storage area; as discussed, and as illustrated in the photographic FIGS. 29 through 35 e , by example. 
     In embodiments, the tonneau accessory  10  (or winder) includes a telescopically extensible base assembly having a central portion and at least one slidably communicating subassembly member; as illustrated, by example, in FIGS. 9 through 28. The central portion of the base assembly and at least one slidably communicating subassembly have a lengthwise outer surfacing; and have and define along the lengthwise outer surfacing at least one respective coupling attachment members or coupling-attachment system or arrangement for engaging and connecting to a vehicle tonneau cover. The assembly is, therefore, positionally adjustable and releasably couple-able to a number of preselected perimeter, point or axis coupling locations which are part and parcel of an attachment or connecting members, arrangement or system provided with a vehicle tonneau cover or like cover or covering. 
     Throughout the preferred embodiments of the present invention and accessory  10  disclosed, taught and illustrated herein (FIGS. 1 through 35 e ); various examples of preferred shapes and configurations of the base members and assemblies utilized in the present invention are set forth; such as circular or cylindrical or arcuate, ellipsoid, elliptical and having walls or a configuration which has both linear and arcuate surfaces. It will, therefore, be understood, within the scope and spirit of the present invention, that the perspective, cross-sectional, end view, widthwise or lengthwise configurational aspects of the base members or support members  12 ,  40 ,  50 ,  60 ,  90  and  92 ; as well as their associated and included parts and elements (such as the coupling members, etc.) disclosed or illustrated herein; can be provided in many different shapes and configurations. 
     Reference is now made to FIGS. 29 through 35 e . A method for positioning and storing a vehicle tonneau cover having a number of perimeter ends at least two of which have coupling attachment members, in relation to a walled or overhang rib supported vehicle bed storage area of a pickup truck includes releasing and detaching a number of coupling attachment members of a first perimeter end of the vehicle tonneau cover from their installed locations on or proximal to a rear walled portion or overhang rib supported portion of the walled vehicle bed storage area of the pickup truck, attaching the number of coupling attachment members of the first perimeter end of a vehicle tonneau cover along a lengthwise oriented rod member, lifting the rod member in a generally upward motion freeing a plurality of any existing attachment locations of the vehicle tonneau cover from securement to the walled vehicle bed storage area or a overhang rib supported portion, winding the lengthwise oriented rod member in a counter-clockwise manner while moving and positioning the rod member to a front wall of the walled vehicle bed storage area, proximal to a cab area of the pickup truck, so that the vehicle tonneau cover is wrapped about the lengthwise oriented rod member and the rod member, contemporaneously, travels and flows with the vehicle tonneau cover as the tonneau cover is being wrapped and positioned proximal to the cab area of the pickup truck, and storing the vehicle tonneau cover as wrapped in the winding step, and, optionally, positioned proximal to the cab area of the pickup truck, until further positioning or placement is desired. 
     The method further includes, in part, after the above referenced storing step: winding the lengthwise oriented rod member in a clockwise manner while moving and positioning the rod member to a back wall portion or overhang support rib of the walled vehicle bed storage area, so that as the vehicle tonneau cover is unwrapped from about the rod member and the rod member, the rod member moves and floats, contemporaneously, with the vehicle tonneau cover, in suspension therewithin, as it is being moved and positioned; detaching and releasing the number of coupling attachment members of the first perimeter end of the vehicle tonneau cover from the rod member; attaching the number of coupling attachment members of the first perimeter end of the vehicle tonneau cover to the back wall portion or overhead rib support portion of the walled vehicle bed storage area; removing the rod member; and storing the rod member in a preselected positional storage area in relation to the walled vehicle bed storage area of the pickup truck, as a separate accessory, until needed, and selected for use again.
