Belly-supporting treadmill

Abstract

A belly-supporting treadmill includes a base, a loop supported on the base, a strut supported on the base and a contact unit connected to the strut above the loop. The contact unit is adapted to contact a user's belly to prevent the user from falling while exercising on the loop.

1 . A belly-supporting treadmill comprising:
 a base;   a loop supported on the base;   a strut supported on the base; and   a contact unit connected to the strut and located above the loop, wherein the contact unit is adapted to contact a user's belly to prevent the user from falling while exercising on the loop.   
     
     
         2 . The belly-supporting treadmill according to  claim 1 , wherein the contact unit comprises a buffer selected from the group consisting of a tubular buffer and a planar buffer. 
     
     
         3 . The belly-supporting treadmill according to  claim 1 , wherein the strut is selected from the group consisting of a rod, a tube and a telescopic element. 
     
     
         4 . The belly-supporting treadmill according to  claim 3 , wherein the strut comprises:
 an external tube connected to the base; and   an internal tube formed with a first end movably inserted in the external tube and a second end connected to the contact unit.   
     
     
         5 . The belly-supporting treadmill according to  claim 1 , further comprising a frame supported on the base, wherein the first the strut is pivotally connected to the frame at an end and connected to the contact unit at another end. 
     
     
         6 . The belly-supporting treadmill according to  claim 5 , further comprising a pad unit connected to one of the frame and the strut to reduce impact on the frame from the strut. 
     
     
         7 . The belly-supporting treadmill according to  claim 5 , further comprising a connective unit for pivotally connecting the strut to the frame and confining the pivoting of the contact unit relative to the frame in a range. 
     
     
         8 . The belly-supporting treadmill according to  claim 7 , wherein the connective unit comprises two lateral strips extending parallel to each other, wherein the strut is located between and pivotally connected to the lateral strips. 
     
     
         9 . The belly-supporting treadmill according to  claim 8 , wherein each of lateral strips comprises several positioning apertures, wherein a pin is inserted in a selected one of the positioning apertures of each of the lateral strips to confine the pivoting of the strut relative to the lateral strips in a range. 
     
     
         10 . The belly-supporting treadmill according to  claim 7 , further comprising a pad unit connected to one of the frame, the strut and the connective unit to reduce impact on the frame from one of the strut and the connective unit. 
     
     
         11 . The belly-supporting treadmill according to  claim 10 , wherein the pad unit comprises at least one pad. 
     
     
         12 . The belly-supporting treadmill according to  claim 10 , wherein the pad unit comprises:
 a threaded bolt formed with a head for contact with the frame and a body movably inserted in the connective unit;   a nut engaged with the threaded bolt; and   a spring compressed between the connective unit and the head of the threaded bolt, thereby biasing the head of the threaded bolt toward the frame.
