ABSTRACT:
An adjustable mobile base includes a closed loop frame which has a plurality of angled members and a plurality of tubular connectors interconnecting the angled members. Each of the angled members is formed with a corner and has two tube sections. Each of the tube sections is formed with a plurality of spaced first engaging through holes which extends in the direction of a longitudinal axis of the tube section. Each of the angled members further has a triangular support plate secured on the corner. Each of the tubular connectors has two ends slidably inserted into a respective one of the tube sections of the angled members. Each of the tubular connectors is formed with a plurality of spaced second engaging through holes which are aligned with the first engaging through holes. A plurality of locking bolt units respectively extend through the aligned first and second through holes so as to join the tubular connectors and the angled members. Adjustments in the size of the mobile base can be achieved by varying the degree of insertion of the tube connectors in the tube sections of the angled members, thereby permitting the mobile base to fit machines of different sizes.
