The present invention relates to a folding device which adjusts the rising angle of the frame and the frame can be folded to upright position by a driving mechanism.
A conventional treadmill 1 is disclosed in
The present invention intends to provide folding device for a treadmill that includes a support frame and a sliding frame which is pivotably connected to the support frame. The sliding frame is connected to an end of the frame and a driving device is engaged with a branch of the sliding frame so as to drive the sliding frame to adjust the frame or to fold the frame.
The present invention relates to a folding device of a treadmill and the folding device comprises a support frame which has a first end thereof pivotably connected to the base of the treadmill and a second end of the support frame is pivotably connected to a first end of a sliding frame. A second end of the sliding frame is pivotably connected to a frame with a running belt of the treadmill. The sliding frame has sliding members slidably connected to tracks of the base and can be disengaged from openings of the tracks when the frame is raised. A driving device has one end connected to the frame and the other end of the driving device is pivotably connected to a branch of the sliding frame.
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.
A folding device comprises a support frame 20 which has a first end 24 thereof pivotably connected to the base 10 and a second end 23 of the support frame 20 is pivotably connected to a first end 35 of a sliding frame 30. A second end 34 of the sliding frame 30 is pivotably connected to a lug 45 extending from an underside of the front end 46 of the frame 40. The sliding frame 30 has sliding members 31 as shown in
A driving device having one end connected to a lug 41 on the frame 40 and includes a motor 42 which has a threaded output rod 43. A branch 32 is connected to the sliding frame 30 and a nut 33 is connected to the branch 32. The threaded output rod 43 threadedly extends through the nut 33.
When using the frame 40, the support frame 20 is oriented in horizontal position as shown in
Further referring to
It is noted that both of the first end 35 and the second end 34 of the sliding frame 30 can be pivoted upward to change the position of the frame 40. The first end 35 of the sliding frame 30 is located close to the mediate portion of the frame 40 so that it is effective to raise the frame 40 upright. The pneumatic bars 44 and the stretch rod 22 are connected between the support frame 20 and the rear end of the frame 40 so that a less force is needed to raise the rear end of the frame 40.
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.
