(15) FIG. 3C shows the device from FIGS. 1B, 2, 3A, and 3B in a further collapsed configuration. Note that in this view, front and rear stanchions 15 and 17 have been rendered invisible in order to provide more convenient viewing of some of the device's other components. This view provides easy visibility of hitching element 80, as well as a front pivot joint 82 and rear pivot joint 84, where these pivot joints can comprise hinges that allow rotational collapse of the device. The device comprises upper vertical elements 71 and 72, which are movable through telescoping action into and out of lower vertical elements 73 and 74. Also, upper vertical elements 71 and 72 comprise hollow sections which are adapted to accommodate front and rear stanchions 15 and 17, as will be shown in subsequent figures.
(16) FIG. 3D shows the device from FIGS. 1B, 2, 3A, 3B, and 3C in a vertically collapsed configuration. In this view, upper vertical elements 71 and 72, as well as front and rear stanchions 15 and 17 which have been rotated and contained within the upper vertical elements 71 and 72 (see FIG. 3E), have been slid into empty sections of lower vertical elements 73 and 74.
(17) FIG. 3E shows a zoomed-in view of the device which depicts empty spaces 67 and 68, into which front and rear stanchions 15 and 17 can be rotated and positioned, after which upper vertical elements 71 and 72 can be telescopically moved into lower vertical elements 73 and 74 (see previous figures).
(18) FIG. 3F shows a zoomed-in view of the device which depicts space holders 61 which, in this embodiment, comprise two holes apiece, and which can be slid in both directions along cargo support element 62. (Note that the space holders 61 depicted in this embodiment comprise an arc shape, allowing them to surround cargo on multiple sides.) Cargo such as bicycles can be secured to the device by placing an upper space holder around a top surface of the cargo, sliding cargo support element 62 through one hole of space holder 61, sliding cargo support element 62 under a bottom surface of the cargo, and finally sliding cargo support element 62 through another hole in space holder 62. In this way, the cargo ends up with its bottom surface hanging on cargo support element 62, and its top surface and side surfaces surrounded by space holder 61. Examples of cargo which can be secured in this manner include bicycle frames, or sections of bicycle wheels. Also in this view, a directional arrow 63 shows a direction in which cargo support element 62 can be shortened by using a telescoping mechanism. Further in this view, a directional arrow 64 illustrates an example direction of rotation of stanchion 17 into the hollow sections of the lower vertical element 73, 74 (see also FIG. 3C).
