    • A folding mechanism for a treadmill having a main frame, a platform and a shaft mounted on the main frame. The main frame is adapted for mounting a motor to impart rotary motion to a worm. Meanwhile, the main frame is rigidly connected to a base frame having an sliding groove or rail with an open side. The platform includes front and rear rollers on the under surface thereof. The front rollers are slidably fitted in the sliding rail. The shaft is mounted on the main frame while a yoke with a crossbar and two supporting arms is rotatably mounted on the shaft. The crossbar includes a worm wheel engaging with the worm, and the free end of the supporting arms is pivotally connected to both sides of the platform. Based on the above-mentioned, the treadmill's platform can be lifted in an inclined position. Furthermore, a locking element is employable to fold the platform in a storage position.
    • 一种用于跑步机的折叠机构,其具有安装在主框架上的主框架,平台和轴。 主框架适于安装电机以向蜗杆传递旋转运动。 同时,主框架刚性地连接到具有开口侧的滑动槽或轨道的基座框架。 该平台包括在其下表面上的前辊和后辊。 前轮可滑动地安装在滑轨中。 轴安装在主框架上,而具有横梁和两个支撑臂的轭可旋转地安装在轴上。 横杆包括与蜗杆啮合的蜗轮,并且支撑臂的自由端枢转地连接到平台的两侧。 基于上述,跑步机的平台可以在倾斜的位置被提升。 此外,锁定元件可用于将平台折叠在存储位置。
