Definitions

  • the present invention relates to a mechanism that adjusts the inclination angle of the belt frame and folds the belt frame upright.
  • a conventional treadmill generally includes a base, a belt frame which has one end pivotably connected to the base and an endless belt is connected to the frame.
  • the endless belt can also be driven by a motor so that the users set desired speed of the belt to exercise.
  • the conventional treadmills generally includes a function of adjustment of the inclination of the belt frame so as to provide different slope for the belt frame.
  • a common way to adjust the inclination of the belt frame employs a mechanism that raises one end of the belt frame.
  • such mechanism can only be used for the adjustment of the belt frame and cannot be used for folding the belt frame.
  • U.S. Pat. No. 6,527,679 discloses a folding mechanism which uses a motor and a threaded rod which is driven by the motor and a connection member pivotably connected to the belt frame is movably mounted to the threaded rod so that when the threaded rod is rotated by the motor, the connection member pivots the frame. It is noted that the folding mechanism can only be used for folding the belt frame and is not able to adjust the inclination of the belt frame. Similarly, another prior art shown in FIG. 10 , discloses a similar folding mechanism which is duly used for folding the belt frame 50 .
  • the present invention intends to provide a mechanism which includes a support frame driven by a motor and the support frame may fold and adjust the belt frame.
  • the present invention relates to a treadmill which comprises a base and a belt frame has a first end pivotably connected to the base and a second end of the belt frame is a free end.
  • An endless belt is mounted to the belt frame.
  • a support frame is pivotably connected to the base and is driven by a mechanism so that the support frame can be pivoted relative to the base.
  • the support frame may also pivot the belt frame upright.
  • FIG. 1 is a perspective view to show the treadmill of the present invention
  • FIG. 2 shows the belt frame is adjusted to have a large angle relative to the floor
  • FIG. 3 is a side view of the treadmill as shown in FIG. 2 ;
  • FIG. 4 shows the belt frame is adjusted to have a small relative to the floor
  • FIG. 5 is a side view of the treadmill as shown in FIG. 4 ;
  • FIG. 6 shows that the belt frame is folded by the support frame
  • FIG. 7 shows a side view of the treadmill in FIG. 6 ;
  • FIG. 8 shows that the belt frame is folded upright
  • FIG. 9 is a side view to show the treadmill as disclosed in FIG. 8 .
  • FIG. 10 shows the frame is pivoted relative to the base of the treadmill by the folding device of a prior art.
  • the treadmill of the present invention comprises a base 10 with two posts 11 extend from the two side rails of the base 10 and a control panel 13 is connected between the two posts 11 .
  • a belt frame 20 has a first end pivotably connected to the base 10 and a second end of the belt frame 20 is a free end which has two wheels connected to an underside thereof.
  • a support deck 22 is connected to the belt frame 20 and two pairs of rollers 23 , 24 are connected on the two sides of the belt frame 20 and located corresponding to two ends of the support deck 22 .
  • An endless belt 21 reeves through the two pairs of rollers 23 , 24 and the support deck 22 is located beneath an upper portion of the endless belt 21 , so that the user may run on the moving endless belt 21 and the load is supported on the support deck 22 .
  • a support frame 30 is pivotably connected to the base 10 by two links 12 which are pivotably connected between the two posts 11 and the support frame 30 .
  • Two sides of the support frame 30 are located beneath of the tow sides of the belt frame 20 and two wheels 31 are connected to an underside of the two sides of the free end of the support frame 30 .
  • the belt frame 20 , the base 10 and the support frame 30 shares a common pivot axis.
  • a mechanism 40 for driving the support frame 30 to be pivoted relative to the base 10 includes a motor 42 , a variator 41 connected to the motor 42 , an output shaft 43 connected to the variator 41 and an active wheel 44 connected to the output shaft 43 .
  • a passive wheel 45 is engaged with the active wheel 44 and located on the pivot axis of the support frame 30 .
  • the active wheel 44 includes first teeth 440 which are engaged with second teeth 450 on the passive wheel 45 .
  • the first end of the belt frame 20 can be adjusted relative to the floor so as to set different angles and inclination of the belt frame 20 as shown in FIGS. 3-6 .
  • the posts 11 are pivoted relative to the base 10 when the support frame 30 is rotated relative to the base 10 so that the control panel 13 can also be adjusted together with the adjustment of the belt frame 20 and this is convenient for the users to use the control panel 13 .
  • the treadmill further includes a driving device 50 for driving the rollers 23 so as to drive the endless belt 21 .
  • the driving device 50 includes a motor 51 which has a first pulley 52 , and a second pulley 53 is connected to the roller 23 that is driven by the motor 51 .
  • a transmission belt 54 reeves through the first and second pulleys 52 , 53 so that the power of the motor 51 is transferred to the first pulley 52 via the transmission belt 54 to drive the endless belt 21 .
  • the support frame 30 keeps on pivoting about the pivot axis, it touches the two sides of the belt frame 20 and pivots the belt frame 20 upward till the belt frame 20 is pivoted to upright position.
