Abstract
A treadmill includes a treadmill that 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 to lift the first end of the belt frame to adjust the inclination of the belt frame. The support frame may support and lift the whole belt frame to fold the belt frame upright.
Description
- 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. However, such mechanism can only be used for the adjustment of the belt frame and cannot be used for folding the belt frame.
- In order to save the space occupied by the treadmill, some treadmills are equipped with a folding device which allows the frame to be pivoted relative to the base. 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 thebelt 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.
- The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.

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 inFIG. 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 inFIG. 4 ; -
FIG. 6 shows that the belt frame is folded by the support frame; -
FIG. 7 shows a side view of the treadmill inFIG. 6 ; -
FIG. 8 shows that the belt frame is folded upright; -
FIG. 9 is a side view to show the treadmill as disclosed inFIG. 8 , and -
FIG. 10 shows the frame is pivoted relative to the base of the treadmill by the folding device of a prior art. - Referring to FIGS. 1 to 5, the treadmill of the present invention comprises a
base 10 with twoposts 11 extend from the two side rails of thebase 10 and acontrol panel 13 is connected between the twoposts 11. Abelt frame 20 has a first end pivotably connected to thebase 10 and a second end of thebelt frame 20 is a free end which has two wheels connected to an underside thereof. Asupport deck 22 is connected to thebelt frame 20 and two pairs ofrollers belt frame 20 and located corresponding to two ends of thesupport deck 22. Anendless belt 21 reeves through the two pairs ofrollers support deck 22 is located beneath an upper portion of theendless belt 21, so that the user may run on the movingendless belt 21 and the load is supported on thesupport deck 22. - A
support frame 30 is pivotably connected to thebase 10 by twolinks 12 which are pivotably connected between the twoposts 11 and thesupport frame 30. Two sides of thesupport frame 30 are located beneath of the tow sides of thebelt frame 20 and twowheels 31 are connected to an underside of the two sides of the free end of thesupport frame 30. In this embodiment, thebelt frame 20, thebase 10 and thesupport frame 30 shares a common pivot axis. - A
mechanism 40 for driving thesupport frame 30 to be pivoted relative to thebase 10 includes amotor 42, avariator 41 connected to themotor 42, anoutput shaft 43 connected to thevariator 41 and anactive wheel 44 connected to theoutput shaft 43. Apassive wheel 45 is engaged with theactive wheel 44 and located on the pivot axis of thesupport frame 30. In this embodiment, theactive wheel 44 includesfirst teeth 440 which are engaged withsecond teeth 450 on thepassive wheel 45. - By pivoting the
support frame 30, the first end of thebelt frame 20 can be adjusted relative to the floor so as to set different angles and inclination of thebelt frame 20 as shown inFIGS. 3-6 . It is noted that theposts 11 are pivoted relative to thebase 10 when thesupport frame 30 is rotated relative to thebase 10 so that thecontrol panel 13 can also be adjusted together with the adjustment of thebelt frame 20 and this is convenient for the users to use thecontrol panel 13. - Further referring to FIGS. 6 to 9, the treadmill further includes a
driving device 50 for driving therollers 23 so as to drive theendless belt 21. Thedriving device 50 includes amotor 51 which has afirst pulley 52, and asecond pulley 53 is connected to theroller 23 that is driven by themotor 51. Atransmission belt 54 reeves through the first andsecond pulleys motor 51 is transferred to thefirst pulley 52 via thetransmission belt 54 to drive theendless belt 21. When thesupport frame 30 keeps on pivoting about the pivot axis, it touches the two sides of thebelt frame 20 and pivots thebelt frame 20 upward till thebelt frame 20 is pivoted to upright position. - While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
