Folding treadmill

Abstract

A folding treadmill includes a tread base supported by a foot structure which has guide plates formed with elongated slots on two sides of the tread base. The tread base is connected pivotally on the base support through pivot members which are mounted movably within the respective slots so that the tread base is turnable between a folded position and an unfolded position and movable rearward when the tread base turns to the folded position or forward when the tread base turns to the unfolded position. The foot structure further includes a guide rail structure on two sides of the tread base to support movably a first roller which is attached to the tread base and a lifting device for lifting the tread base.

1 . A folding treadmill comprising:
 (a) a base support having a foot structure positioning on a surface;   (b) a tread base including a frame and an endless belt mounted to the frame, the tread base being rotatable between a use position and a storage position;   (c) at least one upward member extending from the foot structure and having an open therein;   (d) a coupler including left and right coupling members, each of the coupling members having a second arm pivotally connected to the tread base and a first arm extending upwardly from the front portion of the second arm, the first arm being substantially perpendicular to the second arm, the upper portion of the first arm connected to the open of the upward member;   (e) an inclining device connected between the tread base and the coupler to move the tread base between a non-inclined and an inclined position; and   (f) a pivot member mounted between the upper portion of the first arm of one of the coupling members and the open of the upward member wherein the first arm is substantially perpendicular to the surface when the tread base is in the use and non-inclined position and the first arm is substantially parallel to the surface when the tread base is in the storage and non-inclined position.   
   
   
       2 . The folding treadmill of  claim 1 , wherein the open of the upward member is a slot which extends substantially in a front-to-rear direction. 
   
   
       3 . The folding treadmill of  claim 2 , wherein the pivot member coupled within the slot for moving substantially along the front-to-rear direction. 
   
   
       4 . The folding treadmill of  claim 3 , wherein the pivot member is moved rearward when the tread base is moved from the use position to the storage position. 
   
   
       5 . The folding treadmill of  claim 3 , wherein the pivot member is moved downward when the tread base is moved from the use position to the storage position. 
   
   
       6 . The folding treadmill of  claim 5 , wherein the pivot member is respectively at lowest position within the slot when the tread base is in the storage position. 
   
   
       7 . A folding treadmill comprising:
 (a) a base support having a foot structure positioning on a surface;   (b) a tread base including a frame and an endless belt mounted to the frame, the tread base being rotatable between a use position and a storage position;   (c) at least one upward member extending from the foot structure and having an open therein;   (d) a coupler including left and right coupling members, each of the coupling members having a second arm pivotally connected to the tread base and a first arm extending upwardly from the front portion of the second arm, the first arm being substantially perpendicular to the second arm, the upper portion of the first arm connected to the open of the upward member;   (e) an inclining device connected between the tread base and the coupler to move the tread base between a non-inclined and an inclined position; and   (f) a pivot member mounted between the upper portion of the first arm of one of the coupling members and the open of the upward member wherein the first arm is substantially parallel to the surface when the tread base is in the storage and non-inclined position which has an included angle of 80 degrees to 90 degrees relative to the surface.
