Benefits of technology

[0004] 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 ba

Problems solved by technology

Besides, the longer travel distance the pneumatic bar extends, the higher possibility that the pneumatic bar 8 could be damaged.

Embodiment Construction

[0016] Referring to FIG. 1, the treadmill of the present invention comprises a base 10 and a frame 40 with a running belt connected thereto which is not shown. The front end of the frame 40 is located above the frame 10 and the rear end of the frame 40 has a wheel supported under the frame 40.

[0017] 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 FIG. 3 slidably connected to tracks 11 of the base 10. The tracks 11 each have an opening 111 as shown in FIG. 6 so that the sliding members 31 can be disengaged from the openings 111 of the tracks 11 when the frame 40 is raised as shown in FIG. 1. the support frame 20 include...

Abstract

A treadmill includes a base and a frame with a running belt is connected to a folding device connected to the base. The folding device includes a support frame which has a first end thereof pivotably connected to the base 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 the frame. The sliding frame includes sliding members slidably connected to tracks of the base. The sliding members can be disengaged from openings defined in 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 rising angle of the frame can be adjusted by lifting the second end of the sliding frame. When the frame is folded to upright position, the first end of the sliding frame is raised and pivoted upward the second end of the support frame.

Description

FIELD OF THE INVENTION [0001] 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. BACKGROUND OF THE INVENTION [0002] A conventional treadmill 1 is disclosed in FIG. 7 and generally includes two support bars 2 and 3 which has one end pivotably connected with each other and the frame 1 of the treadmill is connected to the pivotal point of the support bars 2 and 3. The frame 1 has only one point connected with the two support bars 2 and 3. The rising angle of the frame 1 is limited by the length of the support bars 2 and 3. Another conventional treadmill is shown in FIG. 8 which includes two support bars 5 and 6, and a connection bar 4 is connected between the frame and the pivotal point of the two support bars 5 and 6. The other end of the support bar 6 is movably engaged in a rail. This is similar the mechanism disclosed in FIG. 7 and does not improve the shortcomings. FI...
