A collapsible mechanism for a treadmill is composed of a support frame, a stand, and an operational console. The stand includes a frame body, a first positioning assembly, and a second positioning assembly. The frame body has a bottom side pivotably attached to the support frame in such a way that the frame body is collapsible relative to the frame. The first and second positioning assemblies are connected with the frame body and the support frame separately. Each of the first and second positioning assemblies includes a first (second) fastener and a first (second) sheet member. The first and second fasteners are inserted through the first and second sheet members separately. Each of the first and second sheet members includes two first specific positions. The operational console is pivotably attached to a top side of the frame body and collapsible relative to the stand.

Collapsible mechanism for treadmill

A supporting structure for a treadmill includes an outer tube, an inner tube and a spring means. The outer tube has an inner wall and a protrusion. The outer tube at where the protrusion exists has an outer-tube internal diameter r. The protrusion and the inner wall are separated by a vertical distance L. The inner tube is telescoped within the outer tube and has a positioning hole. The inner tube at where the positioning hole exists has an inner-tube external diameter R, wherein (R+L)&#x3c;r. When the inner tube is parallel to the outer tube and the protrusion is aligned with the positioning hole, the spring means enters the protrusion into the positioning hole. When the inner tube is inclined with respect to the outer tube, the protrusion is disengaged from the positioning hole, allowing the inner tube to move within the accommodating space.
