Abstract

A folding mechanism for a treadmill including a handrail assembly pivotally attached by a coupling shaft to both sides of the front end of a base frame of a treadmill. Meanwhile, a positioning unit with an engaging element is provided such that the handrail assembly can be downwardly moved toward the base frame in an initial storage position. Moreover, an n-shaped foot rest is swivelably disposed at the center of the coupling shaft by a connecting arm. In this way, the n-shaped foot rest can be extended from a front crossbar of the base frame by the synchronic swiveling action of the coupling shaft when the handrail assembly is moved in the initial storage position. In match with an n-shaped supporting frame, the base frame can be brought into an upright position to achieve a vertical and stable folding state.

Claims

1. A folding mechanism for a treadmill, comprising a handrail assembly being pivotally attached by a coupling shaft to both sides of the front end of a base frame of a treadmill, a positioning unit with an engaging element being provided such that the handrail assembly can be downwardly moved toward the base frame in an initial storage position, a n-shaped foot rest being swivelably disposed at the center of the coupling shaft by a connecting arm,

whereby the n-shaped foot rest can be extended from a front crossbar of the base frame by the synchronic swiveling action of the coupling shaft when the handrail assembly is moved in the initial storage position;

in match with an n-shaped supporting frame, the base frame can be brought into an upright position to achieve a vertical and stable folding state.

2. The folding mechanism for a treadmill as recited in claim 1, wherein the positioning unit includes an engaging element, a coupling shaft hidden within the handrail assembly, an elastic element and a positioning bar, and wherein the positioning bar has a first insertion hole and a second insertion hole at the end surface thereof.
