Treadmill folding device having locking function and method for using the same

Abstract

A treadmill folding device having a locking function includes a treadmill deck, a first upright pole, a control panel and a first lockable telescopic mechanism. The control panel is mounted to an upper end of the first upright pole. A lower end of the first upright pole is movably connected to a side of the treadmill deck. The first lockable telescopic mechanism is connected between a middle portion of the first upright pole and the side of the treadmill deck. The first upright pole, the treadmill deck and the first lockable telescopic mechanism form a triangular area when the first lockable telescopic mechanism is in an extended state. The first upright pole is parallel to or about parallel to the treadmill deck when the first lockable telescopic mechanism is in a retracted state.

The treadmill folding device as claimed in  claim 1 , further comprising a second lockable telescopic mechanism, a rear end of the control panel being movably connected to the upper end of the first upright pole, the control panel being rotatable forward and backward relative to the first upright pole, the second lockable telescopic mechanism being hingedly connected between an underside of a middle portion of the control panel and a front side of the middle portion of the first upright pole. 
     
     
         3 . The treadmill folding device as claimed in  claim 1 , further comprising a second lockable telescopic mechanism, a front end of the control panel being movably connected to the upper end of the first upright pole, the control panel being rotatable forward and backward relative to the first upright pole, the second lockable telescopic mechanism being hingedly connected between an underside of a middle portion of the control panel and a rear side of the middle portion of the first upright pole. 
     
     
         4 . The treadmill folding device as claimed in  claim 1 , further comprising a second upright pole, a front end of the control panel being movably connected to the upper end of the first upright pole, the control panel being rotatable forward and backward relative to the first upright pole, the second upright pole being hingedly connected between a middle portion of the control panel and the side of the treadmill deck, the treadmill deck, the control panel, the first upright pole and the second upright pole forming a parallelogram mechanism. 
     
     
         5 . The treadmill folding device as claimed in  claim 1 , further comprising a second upright pole, a middle portion of the control panel being movably connected to the upper end of the first upright pole, the control panel being rotatable forward and backward relative to the first upright pole, the second upright pole being hingedly connected between a front portion of the control panel and the side of the treadmill deck, the treadmill deck, the control panel, the first upright pole and the second upright pole forming a parallelogram mechanism. 
     
     
         6 . The treadmill folding device as claimed in  claim 1 , wherein the first lockable telescopic mechanism includes one of a self-locking traction gas spring, a hydraulic cylinder, a pneumatic cylinder and an electric push rod. 
     
     
         7 . The treadmill folding device as claimed in  claim 2 , wherein the second lockable telescopic mechanism includes one of a self-locking traction gas spring, a hydraulic cylinder, a pneumatic cylinder and an electric push rod. 
     
     
         8 . The treadmill folding device as claimed in  claim 3 , wherein the second lockable telescopic mechanism includes one of a self-locking traction gas spring, a hydraulic cylinder, a pneumatic cylinder and an electric push rod. 
     
     
         9 . The treadmill folding device as claimed in  claim 6 , wherein the self-locking traction gas spring includes a cylinder barrel, a piston, a piston rod, a needle valve, and an end cap, the piston is disposed in the cylinder barrel, the piston is sealedly slidably fitted in the cylinder barrel, the end cap is mounted at an opening of the cylinder barrel, the piston is fixedly connected to an inner end of the piston rod, the piston rod extends outward from a central hole of the end cap, a sealing ring is provided between an outer side wall of the piston rod and an inner side wall of the end cap, a rodless chamber of the cylinder barrel is provided with oil, a rod chamber of the cylinder barrel is provided with a gas, the needle valve is disposed in the piston rod, a valve of the needle valve is disposed on the piston, and a switch of the needle valve is disposed at an outer end of the piston rod. 
     
     
         10 . The treadmill folding device as claimed in  claim 9 , wherein the switch is an eccentric rotary switch, the eccentric rotary switch includes a rotary handle and a cam, the cam is rotatably mounted to the outer end of the piston rod, the rotary handle is fixedly connected to the cam, and the cam drives a needle rod of the needle valve to move up and down. 
     
     
         11 . A method for using the treadmill folding device as claimed in  claim 1 , comprising: (1) folding downward: releasing the first lockable telescopic mechanism and retracting the first lockable telescopic mechanism for the first upright pole to be turned and folded relative to the treadmill deck to an ultimate storage state; (2) unfolding upward: extending the first lockable telescopic mechanism for the first upright pole to unfold automatically to an ultimate state and locking the first lockable telescopic mechanism.
