The epicyclical gear train may be assembled so the planet gear 126 rolls on the inside of the pitch circle of the ring gear 122 (also called an annular gear). In this case, the curve traced by a point on the pitch circle of the planet gear 126 is a hypocycloid. The combination of epicycle gear trains with the planet gear 126 engaging both the sun gear 124 and the ring gear 122 is called a planetary gear train. The ring gear 122 may be fixed (in position) and the sun gear 124 may be driven (and other options or arrangements are possible).

FIG. 2A , FIG. 2B , FIG. 2C , FIG. 2D and FIG. 2E depict side views of the embodiments of the apparatus 100 of FIG. 1B . In accordance with the embodiments depicted in FIG. 2A , FIG. 2B , FIG. 2C , FIG. 2D and FIG. 2E , the planetary gear assembly 120 is arranged in such a way that the planet carrier 128 is configured to be affixed (selectively attached and detached) to the vehicle frame 902 (such as, to an axle portion of the vehicle frame 902 , etc.). For instance, the planet carrier 128 includes a mounting device 130 configured to directly connect the planet carrier 128 to the vehicle frame 902 . In this arrangement, the planet carrier 128 is held stationary (in a relatively stationary position) relative to the vehicle frame 902 . Referring to FIG. 2A , the planet carrier 128 includes a carrier-extension member 129 , also called a shaft, that extends from the carrier-extension member 129 . The carrier-extension member 129 is configured to extend away from the vehicle frame 902 once the planet carrier 128 is mounted (either directly or indirectly) to the vehicle frame 902 . Referring to FIG. 2B , the carrier-extension member 129 is configured to receive the planet gear 126 . The number of instances of the planet gear 126 may vary as needed. As depicted in FIG. 1D , there are three instances of the planet gear 126 (evenly spaced apart from each other at 120 degree). As depicted in FIGS. 2A to 2E , there are two instances of the planet gear 126 each spaced 180 degrees apart from each other. Referring to FIG. 2C , the sun gear 124 is operatively mounted to the instances of the planet gear 126 (between the planet gears 126 ) in such a way that the teeth of the sun gear 124 operatively mesh (interact) with the teeth of the planet gears 126 . The sun gear 124 has a sun shaft 125 that extends from the sun gear 124 away from the vehicle frame 902 (once the sun gear 124 is mounted to the planet gears 126 , and the planet carrier 128 is mounted to the vehicle frame 902 ). Referring to FIG. 2D , the ring gear 122 is operatively mounted to the planet gears 126 in such a way that the teeth of the ring gear 122 mesh with the teeth of the planet gears 126 . A transferring device 132 includes a transferring input gear 134 and a transferring output gear 136 . The transferring output gear 136 is configured to operatively mesh (interact) with the transferring input gear 134 . The transferring device 132 is operatively connected (mounted) to the sun shaft 125 of the sun gear 124 in such a way that the sun shaft 125 turns (rotates) the transferring input gear 134 , and, in response, the transferring input gear 134 rotates the transferring output gear 136 . The transferring device 132 is coupled to the height-adjusting mechanism 104 . The height-adjusting mechanism 104 includes a first threaded shaft member 138 and a second threaded shaft member 140 . The first threaded shaft member 138 is threadably coupled to the second threaded shaft member 140 . The transferring device 132 is coupled to the first threaded shaft member 138 . Referring to FIG. 2D , in use (in operation), the ring gear 122 is rotated (for instance, manually by the user). This is done in such a way that the sun shaft 125 is rotated. In response to rotation of the sun shaft 125 , the transferring device 132 is activated to rotate the first threaded shaft member 138 . Once the first threaded shaft member 138 is rotated, the second threaded shaft member 140 is rotated relative to the first threaded shaft member 138 . In this way, the second threaded shaft member 140 is linearly translated (up and down) along a substantially vertical direction. Referring to FIG. 2E , the housing assembly 112 includes a stationary housing 142 and a rotatable housing 144 . The rotatable housing 144 is configured to be rotatable relative to the stationary housing 142 . The ring gear 122 is operatively mounted in the rotatable housing 144 . The rotatable housing 144 is rotated in such a way that the ring gear 122 is rotated. In summary, the planet carrier 128 is affixed to the vehicle frame 902 . The ring gear 122 is rotatable (for instance, by the user) once the ring gear 122 receives the height-adjustment force 904 . This action then urges the sun shaft 125 to be rotated, which then causes the height-adjusting mechanism 104 to become linearly height adjusted. It will be appreciated that rotating the ring gear 122 in one direction (such as clockwise) causes the height-adjusting mechanism 104 to become vertically shorter. It will be appreciated that rotating the ring gear 122 in another direction (such as counterclockwise) causes the height-adjusting mechanism 104 to become vertically longer in height. FIG. 3 depicts a side view of an embodiment of the apparatus 100 of FIG. 1B . Referring to the embodiment as depicted in FIG. 3 , the ring gear 122 is affixed (in a stationary position) to the vehicle frame 902 . For instance, the mounting device 130 extends (radially) from the ring gear 122 toward the vehicle frame 902 , and the mounting device 130 affixes the ring gear 122 to the vehicle frame 902 . The planet carrier 128 is rotatable (for instance, by the user) once the planet carrier 128 receives the height-adjustment force 904 . This action urges the sun shaft 125 (in response) to be rotated, which then causes the height-adjusting mechanism 104 to become linearly height adjusted. It will be appreciated that rotating the planet carrier 128 in one direction (such as clockwise) causes the height-adjusting mechanism 104 to become vertically shorter. It will be appreciated that rotating the planet carrier 128 in another direction (such as counterclockwise) causes the height-adjusting mechanism 104 to become vertically longer in height. In accordance with an embodiment, the transferring device 132 may include a crown and pinion gear (by way of example). In accordance with an embodiment, the height-adjusting mechanism 104 includes a pulley that is operatively mounted to the sun gear 124 . The height-adjusting mechanism 104 also includes a cable that is operatively mounted to a telescopic tubing device having a tube guide. The tube guide is configured to prevent twisting (rotation) of the telescopic tubing.
