Retractable steps, such as the step 30, are conventional structures. Consequently, further description is omitted for the sake of brevity.

(35) Further, it should be understood from the drawings and the description hereinbelow, that the retractable step 30 can include any of a variety of designs and structures, such as a retractable step attached to or attachable to the first side wall 22 and/or the tailgate 26.

(36) The first side wall 22 and the second side wall 24 are symmetrically constructed (mirror images of one another) but are otherwise structurally identical. Only the first side wall 22 will be described below for the sake of brevity. However, it should be understood from the drawings and the description herein that the description of the first side wall 22 applies equally to the second side wall 24.

(37) The first side wall 22 includes an outer panel 40 shown in FIGS. 1 and 2, an inner panel 42, a support pillar 44 and an upper panel portion 46 that are shown in FIG. 3. The outer panel 40 is contoured in accordance with an overall exterior design of the cargo area structure 16 and can have any of a variety of contours and/or shapes, or, can have a simple flat or near flat shape. The inner panel 42 can also be contoured and shaped in accordance the cargo area structure 16 design. However, in the depicted embodiment, the inner panel 42 is generally flat and planar extending perpendicularly upward from the floor 20, except in the area of the wheel well.

(38) The upper panel 46 is horizontally oriented and extends in a vehicle lateral inboard direction from an upper end of the outer panel 40. As shown in FIGS. 10, 11 and 12, the upper panel 46 overhangs an upper end of the inner panel 42. The upper panel 46 further defines an upper surface 46a of the first side wall 22.

(39) Each of the first side wall 22 and the second side wall 24 includes a utility track 48. As shown in FIGS. 3-5 and 10-12, the utility track 48 is fixedly attached to the first side wall 22 immediately below the overhang of the upper panel 46. In other words, the upper panel 46 extends inboard over the utility track 48.

(40) The utility track 48 is configured to receive and support cargo area accessories such as those disclosed in commonly assigned U.S. Pat. Nos. 9,623,787, 8,550,757, 8,408,853, 8,052,019 and 7,594,787, which are all incorporated herein by reference in their entirety. The utility track 48 is rigidly and fixedly attached to the first side wall 22 at a location below and adjacent to the upper surface 46a of the upper panel portion 46 of the first side wall 22.

(41) The utility track 48 is fastened to the inner panel 42 of the first side wall 22 via a plurality of pairs of fasteners F.sub.1, as shown in FIGS. 3 and 4. The pairs of fasteners F.sub.1 are vertically aligned and spaced apart from one another.

(42) The utility track 48 is an elongated member shown in cross-section in FIG. 8. The utility track 48 has a generally U-shaped configuration when viewed in cross-section. The U-shape of the utility track 48 defines an elongated hollow channel 50 (hereinafter referred to as the channel 50) surrounded on three sides by parallel walls 52 and base wall 54. Outer ends of the walls 52 are each formed with projections 56 that extend back into the channel 50. The ends of the projections 56 extend into the channel 50 but are spaced apart from the walls 52 and the base wall 54. An elongated opening 58 (a horizontally oriented gap) is defined between the projections 56 is open to the channel 50. Further, the rear end of the utility track 48 is open. The inboard vertical portions of the parallel walls 52 define an upright surface 48a. In other words, since the utility track 48 is fixed to the first side wall 22, the utility track 48 defines the upright surface 48a of the first side wall 22. The utility track 48 also includes a lower flange 54a. A lower one of each of the pairs of fasteners F.sub.1 extends through the lower flange 54a. The base wall 54 and the lower flange 54a are co-planar in the depicted embodiments.

(43) A description is now provided of the handle assembly 14 in accordance with a first embodiment with specific reference to FIGS. 3-15. The handle assembly 14 basically includes a base 60, a grip handle 62 and a locking portion 64. as described in greater detail below.

(44) The base 60 is configured to secure the handle assembly 14 to the first side wall 22. In the first embodiment, the base 60 secures the handle assembly 14 to the utility track 48, which is directly attached to the first side wall 22 and structurally is part of the first side wall 22.

(45) As shown in FIGS. 3 and 4, the grip handle 62 is movable between a stowed orientation (FIG. 3) and an in-use orientation (FIG. 4). The locking portion 64 is operated to freely release the grip handle 62 to that it can be moved (pivoted) between the stowed orientation and the in-use orientation, as described further below. When the locking portion 64 is not operated, it is spring biased to lock the grip handle 62 to either one of the stowed orientation and the in-use orientation, as is also described below.

(46) As shown in FIGS. 7, 8 and 9, the base 60 includes an attachment assembly 68 and a threaded member 70 (a rotatable knob). The attachment assembly 68 is defined by a base member 72 (outer clamping member) and a clamping member 74 (inner clamping member) that are operated to produce a clamping effect by rotation of the threaded member 70. More specifically, the base member 72 and the clamping member 74 are configured to clamp around the projections 56 of the parallel walls 52 of the utility track 48.

(47) The base member 72 is a cylindrically shaped member with a clamping flange 78 and a supporting end 80. The clamping flange 78 is a rectangularly shaped flat flange (as shown in FIGS. 3 and 4) that is configured to overlay the upright surface 48a of the utility track 48 when installed thereto. The clamping flange 78 includes an annular projection 78a that extend into the elongated opening 58 of the utility track 48. The projection 78a is dimensioned to contact the projections 56 within the elongated opening 58 thereby centering the base member 72 between the projections 56 of the parallel walls 52. The supporting end 80 (also referred to as a block member) is a cylindrically shaped portion that has an annular bearing surface 82. a flat end surface 84 and a central bore 86 extending completely through the base member 72. The annular bearing surface 82 is shaped and polished to rotatably support the grip handle 62, as described in greater detail below. The supporting end 80 also includes two openings 80a and 80b that are provided for use with the locking portion 64, as is described in greater detail below.

(48) As shown in FIGS. 7 and 8, the clamping member 74 is an elongated member that has a clamping end 90 and a threaded end 92. The clamping member 74 is installed within the base member 72, extending through the central bore 86 thereof. As shown in FIG. 7, the clamping end 90 is dimensioned to fit and is inserted into the elongated hollow channel 50 of the utility track 48. The clamping end 90 contacts the projections 56 of the parallel walls 52 of the utility track 48. The threaded end 92 is configured to receive internal threads 70a.

(49) The threaded member 70 is a knob or daisy wheel with outer surface contours that enable a vehicle operator or passenger to grip and rotate the threaded member 70 to loosen or tighten the attachment assembly 68. Specifically, the internal threads 70a of the threaded member 70 engage the threaded end 92 of the clamping member 74. When tightened, rotation of the threaded member 70 causes the clamping member 74 to engage and be drawn against the projections 56 of the utility track 48, while the base member 72 is pushed against the upright surface 48a, thereby clamping the projections 56 between the base member 72 and the clamping member 74.

(50) The base 60 also includes a spacer 94 and an annular washer 96. The spacer 94 is basically a thick metal washer that has a first thickness T.sub.1, as shown in FIGS. 7 and 8. The spacer 94 has an outer diameter smaller than the outer diameter of the supporting end 80 of the base member 72. The spacer 94 is positioned between the flat end surface 84 of the supporting end 80 of the base member 72 and the annular washer 96. The annular washer 96 has an outer diameter greater than the outer diameter of the supporting end 80 of the base member 72. The annular washer 96 is installed to the threaded end 92 of the clamping member 74 between the spacer 94 and the threaded member 70.

(51) As shown in FIGS. 7-14, the grip handle 62 includes a pivoting member 100 and a rod-shaped member 102. The pivoting member 100 has an overall rectangular shape, as shown in FIGS. 3-4 and 13-14. The pivoting member 100 has an inner annular surface 104 and a radially inwardly extending annular flange 106 (hereinafter the annular flange 106) that extends radially inward from one end of the pivoting member 100. The inner annular surface 104 is a polished bearing surface that encircles and pivots about the annular bearing surface 82 of the supporting end 80. One or both of the inner annular surface 104 and the annular bearing surface 82 can be coated with a friction reducing material such as graphite, Polytetrafluoroethylene, hydrocarbon-based lubricants, or other suitable lubricating materials.

(52) The annular flange 106 has a thickness T.sub.2 that is smaller than the thickness T.sub.1. With the handle assembly 14 fully assembled, the annular flange 106 extends radially inward and is confined between an outer radial portion of the flat end surface 84 of the supporting end 80 of the base member 72 and the annular washer 96. Consequently, the annular flange 106 and the entire pivoting member 100, with the rod-shaped member 102 of the grip handle 62 is free to pivot about the clamping member 74 and the base member 71 of the base 60. Pivoting movement of the grip handle 62 relative to the supporting end 80 is limited by the locking portion 64 (positioning locking mechanism), as is described further below.

(53) The rod-shaped member 102 of the grip handle 62 is an elongated bar shaped member and can have a rectangular cross-section, or, can have a cylindrical shape, as shown in the first embodiment.

(54) As shown in FIGS. 12-14, the rod-shaped member 102 has a threaded end 102a that screws into a first threaded opening 100a of the pivoting member 100. FIG. 11 depicts the handle assembly 14 in the stowed orientation, while FIG. 12 shows the handle assembly 14 in the in-use orientation.

(55) As shown in FIGS. 10 and 12-14, the locking portion 64 includes a housing 110, a locking pin 112 and a biasing spring 114. The housing 110 includes a threaded surface 110a that threads into a second threaded opening 100b that is aligned with the first threaded opening 100a in the first embodiment. The housing 100 further includes a hollow interior that receives the biasing spring 114 and a portion of the locking pin 112. The biasing spring 114 is compressed by the locking pin 112 when the locking pin 112 is moved to an unlocking orientation, as shown in FIG. 13. The biasing spring 114 biases the locking pin 112 to move to a locking orientation as shown in FIG. 14. The biasing spring 114 biases the locking pin 112 to move into the opening 80a when the rod-shaped member 102 of the grip handle 62 is in the stowed orientation, as shown in FIGS. 3, 11 and 14. Further, the spring 114 biases the locking pin 112 to move into the opening 80b when the rod-shaped member 102 of the grip handle 62 is in the in-use orientation, as shown in FIGS. 4, 12 and 13.

(56) In other words, the locking portion 64 (a position locking mechanism) is configured such that in the locking orientation (FIGS. 12 and 14), the pivoting member 100 and the grip handle 62 are prevented from pivoting relative to the supporting end 80 (the block member) of the base member 72. In the unlocked orientation (FIG. 13) the pivoting member 100 and the grip handle 62 are free to pivot about the supporting end 80 between the stowed orientation and the in-use orientation.

(57) As shown in FIGS. 4 and 12, when the grip handle 62 of the handle assembly 14 is in the in-use orientation, the grip handle 62 extends in an upright direction. Herein, the upright direction with respect to the in-use orientation can include a vertical orientation of the grip handle 62 or a slightly inclined orientation, as shown in FIG. 18 in the second embodiment.

(58) The in-use orientation is determined by the position of the opening 80b in the support end 80 of the base member 72 of the base 60. Specifically, the locking pin 112 of the locking portion 64 (the position locking mechanism) extends into the opening 80a with the grip handle 62 in the stowed orientation, as shown in FIG. 14. The locking pin 112 of the locking portion 64 extends into the opening 80b with the grip handle 62 in the in-use orientation, as shown in FIG. 13. In FIGS. 13 and 14, the openings 80a and 80b extend in directions that are perpendicular to one another. Alternatively, the openings 80a and 80b can be oriented such that they extend in directions that define an angle greater than 90 such that the stowed orientation remains horizontal, but the in-use orientation is slightly inclined rearward relative to the vehicle, as shown in FIG. 18 of the second embodiment.

(67) The base 360 includes a threaded member 370 that operates an attachment assembly (not shown) that clamps to the utility track in a manner similar to that described in the first embodiment. Therefore, further description will be omitted for the sake of brevity. The base 360 also includes a support tube 360a that receives the grip handle 362, such that the grip handle 362 is slidable through the support tube 360a. Specifically, the grip handle 362 is slidable between an in-use orientation show in in FIGS. 21 and 23-25. When in the in-use orientation, the grip handle 362 extends in a horizontal direction parallel to the first side wall 22. When in the stowed orientation (FIG. 22), the grip handle 362 also extends in the horizontal direction and is positioned within the utility track 48.

(68) Specifically, the grip handle 362 is slidably movable between the stowed orientation and the in-use orientation.

(69) The locking portion 364 (the position locking mechanism) includes a spring biased pin 412 biased by a spring 441 to the locked orientation. The spring biased pin 412 is manually pressed to an unlocked orientation and spring biased to return to a locked orientation. With the locking portion 364 in the locking orientation, the grip handle 362 is prevented from sliding relative to the base 360. In an unlocked orientation, the grip handle 362 is free to slide relative the base 360 between the stowed orientation and the in-use orientation.

Fifth Embodiment

(70) Referring now to FIGS. 21-25, a handle assembly 314 in accordance with a fifth embodiment will now be explained. In view of the similarity between the first and fifth embodiments, the parts of the fifth embodiment that are identical to the parts of the first embodiment will be given the same reference numerals as the parts of the first embodiment. Moreover, the descriptions of the parts of the fifth embodiment that are identical to the parts of the first embodiment may be omitted for the sake of brevity.

(71) In the fifth embodiment, the handle assembly 514 has every component of the handle assembly 514, as described above, except that the threaded member 70 is replaced with a modified threaded member 70, the annular washer 96 is replaced by an annular washer 96 and washers 97 and 98 have been added.

(72) The threaded member 70 includes an annular sleeve portion 70a with external threads. The annular washer 96 includes internal threads that thread to and engage the external threads of the annular sleeve portion 79a. The annular washer 96 serves as a spacer that ensures pivoting movement of the grip handle 62 abut the supporting end 80. One of the new washers 97 and 98 is a friction washer that ensures that when the threaded member 70 is tightened clamping the handle assembly 514 to the utility track 48, the threaded member 70 remains tightened.
