Patent ID: 6923747

Claim:
A foldable treadmill, comprising: a tread assembly having front and rear ends and spaced-apart longitudinal sides extending therebetween; and an A-frame assembly positioned about the front end of the tread assembly, including a front support having an upper end and a lower end that serves as a floor contact, an intermediate support having an upper end hinged to the front support and a lower end that serves as a floor contact, an inclination support having a first end hinged with respect to the front support, thereby defining a first axis of rotation generally parallel with a lateral axis of the tread assembly, and a second end hinged to the front end of the tread assembly, thereby defining a second axis of rotation generally parallel with the lateral axis of the tread assembly, and an intermediate constraint having a first portion operatively attached to the intermediate support and a second portion operatively attached to structure spaced from the intermediate support; wherein the inclination support is rotatable about the first axis of rotation such that the second end of the inclination support vertically displaces the front end of the tread assembly thereby varying the inclination of the tread assembly, and the tread assembly is rotatable about the second axis of rotation to a generally vertical orientation.
