A dual-purpose foldable treadmill includes a drive unit, a base frame, an arm frame, a cantilever panel and a tread frame. The arm frame extends in an upright direction from a wall of the base frame and terminates at a top joining end. The cantilever panel extends transversely from the top joining end. The tread frame is pivotally connected to and foldable relative to the base frame such that a lengthwise line of the tread frame is parallel to the upright direction of the arm frame in the folded position. The folded treadmill can be used as a piece of furniture for storage or as a bench.

1. A dual-purpose foldable treadmill for use on a floor surface, the treadmill comprising: a drive unit;a base frame which is configured to permit said drive unit to be mounted therein, and which extends in a transverse direction to terminate at first and second end walls, said base frame having a rear marginal zone which extends between said first and second end walls;an arm frame including a base segment which is disposed to flank said second end wall, and an arm body which extends from said base segment in an upright direction to terminate at a top joining end, said arm body having an outward surface;a cantilever panel extending from said top joining end in the transverse direction and over said base frame to terminate at a cantilevered end, said cantilever panel including a rear portion; anda tread frame including front and rear marginal regions which are opposite to each other, and defining a lengthwise line extending from said front marginal region to terminate at said rear marginal region, said front marginal region being pivotably mounted on said rear marginal zone about a pivot axis that is oriented in the transverse direction such that said rear marginal region is turnable between an unfolded position, where the lengthwise line is transverse to both the upright and transverse directions, and a folded position, where the lengthwise line is parallel to the upright direction;whereby once said rear marginal region is turned to the folded position and said rear marginal region couples with said rear portion of said cantilever panel, said dual-purpose foldable treadmill can be used as a seating bench, with said arm frame being parallel to the floor surface and said outward surface of said arm body facing away from the floor surface, said arm body serving as a sitting surface. 2. The dual-purpose foldable treadmill as claimed in claim 1, further comprising: a front roller and a rear roller which are respectively journalled on said front marginal region and said rear marginal region so as to be rotatable respectively about front and rear rolling axes that are parallel to the pivot axis, said front roller being coupled with said drive unit so as to be driven thereby; andan endless belt disposed to be entrained about said front and rear rollers. 3. The dual-purpose foldable treadmill as claimed in claim 2, wherein said rear marginal zone has first and second bearing areas which are respectively adjacent to said first and second end walls, said front roller being configured to have first and second front journal ends which are respectively journalled on said first and second bearing areas. 4. The dual-purposed foldable treadmill as claimed in claim 3, wherein said first and second bearing areas are in the form of lugs which respectively include first and second inner tubular surfaces that surround the pivot axis such that the front rolling axis is in line with the pivot axis to thereby permit said first and second front journal ends of said front roller to be journalled on said first and second inner tubular surfaces of said first and second lugs, respectively. 5. The dual-purpose foldable treadmill as claimed in claim 1, wherein said cantilever panel further includes a front portion in addition to said rear portion, said front portion and said rear portion being opposite to each other in a longitudinal direction that is transverse to both the upright direction and the transverse direction, and an upward surface and a downward surface which are opposite to each other in the upright direction, said dual-purpose foldable treadmill further comprising a locking unit which is disposed to lock said rear marginal region to said rear portion so as to lock said rear marginal region in the folded position. 6. The dual-purpose foldable treadmill as claimed in claim 5, wherein said locking unit includes a plug member which includes a deformable base end disposed on and deformable inwardly of said downward surface, and a plug end extending downwardly from said deformable base end, said plug member being disposed proximate to said cantilevered end, anda socket member which is disposed in said rear marginal region such that once said rear marginal region comes into contact with said plug end during displacement to the folded position, said plug end is pressed to move said deformable base end to a deformed position so as to permit said plug end to be trapped in said socket member, thereby locking said rear marginal region in the folded position. 7. The dual-purpose foldable treadmill as claimed in claim 1, wherein said cantilevered end is aligned with said first end wall of said base frame in the upright direction. 8. The dual-purpose foldable treadmill as claimed in claim 1, wherein said cantilever panel has a depression for holding an object therein. 9. The dual-purpose foldable treadmill as claimed in claim 5, wherein said rear portion has a cutout region which extends in the transverse direction to terminate at first and second holding surfaces that are spaced apart from each other by a rear space, said dual-purpose foldable treadmill further comprising a crosspiece which is disposed to span said rear space to interconnect said first and second holding surfaces. 10. The dual-purpose foldable treadmill as claimed in claim 9, further comprising a control panel body disposed in said cantilever panel adjacent to said cutout region and electrically connected to said drive unit. 11. The dual-purpose foldable treadmill as claimed in claim 5, further comprising a pair of foot pads disposed on said cantilevered end and a pair of foot pads disposed on said first end wall of said base frame for resting on the floor surface.
