1. A telescopic support capable of transitioning between an extended position and a retracted position, the telescopic support comprising:
an outer support tube having an interior wall extending along a longitudinal axis of the telescopic support, the interior wall defining an interior space; an inner support receivable within the interior space of the outer support tube, wherein, in a fully retracted position of the telescopic support, a greater portion of the inner support is within the interior space than in a fully extended position of the telescopic support such that a longitudinal length of the telescopic support in the fully retracted position is less than the longitudinal length of the telescopic support in the fully extended position; at least three bearing sets respectively disposed on one of the outer support tube or the inner support, the at least three bearing sets respectively interface with a race set of the other of the outer support tube or the inner support to aid in maintaining alignment of the inner support and the outer support tube along the longitudinal axis of the telescopic support; wherein each of the at least three bearing sets includes at least two roller bearings spaced apart along the longitudinal axis of the telescopic support, each of the at least two roller bearings having a rotational axis substantially directed toward the longitudinal axis of the telescopic support; and a guide plate affixed to an end of the inner support receivable within the interior space of the outer support tube, the guide plate configured to interface with at least two opposing surfaces of the interior wall of the outer support tube to enhance stability between the inner support and the outer support tube along the longitudinal axis of the telescopic support. |
