Abstract
A collapsible treadmill includes a base, a treadbase pivotably mounted on the base, a retractable member having a cylinder and a bar fitted into cylinder. The cylinder is pivotably mounted on the base at an end thereof. The bar is pivotably mounted on the treadbase. A sleeve is fitted onto the cylinder and pivotably mounted on the treadbase together coaxially with the bar. A locking member is pivotably mounted on the sleeve and has a stop lug to be inserted into a stop slot of the sleeve. A biasing member keeps the stop lug of the locking member inserted into the stop slot and engaged against an outer periphery of the cylinder. When the treadbase is at a collapsed position, the locking member can be driven to engage against a distal end surface of the cylinder, thereby automatically securing the treadbase to the collapsed position.
