Abstract
The present invention relates to a rope type folding mechanism for an exercise treadmill. Each end of the U-shaped handrail is provided with a rope wheel whose shaft is pivotably mounted on the extension part at the top of each of the supporting arms. Thereafter, a strong rope is fixed at one side of the rope wheel and pulled downward to the bottom of the frame. When the U-shaped handrail is raised and turned around the shaft, the rope wheel is also rotated to pull the strong rope upward. Thereafter, the frame is raised up to the top by means that the rear roller is turned around the first pivot.
Description
- 1. Field of the Invention
- The present invention relates to a rope type folding mechanism for an exercise treadmill, and more particularly, an exercise treadmill whose frame can be folded or unfolded by moving the handrail. Therefore, the convenience in use is achieved and the safety is ensured.
- 2. Description of the Prior Art
- The frame of the conventional treadmills (for example, the disclosed U.S. Pat. Nos. 5,674,453, and 6,033,347) is designed to be foldable in order to reduce the occupied space and to facilitate the movement thereof. However, these products have to include an auxiliary lifting member (like pneumatic or oil-pressurized cylinder) behind the frame in order to prevent the frame from an unexpected collapse endangering the operator or the other around. Accordingly, the whole design and use show much inconvenience.
- Moreover, this conventional design doesn't fit the old or the disable in waist or lower limbs because they have much difficulty in bending down to perform the folding movement.
- It is a primary object of the present invention to remove the above-mentioned drawbacks and to provide a folding mechanism for an exercise treadmill through which the operator doesn't need to bend down to perform the folding movement of the frame. Furthermore, the frame can be folded to the top at an automatic locking position by means of rope wheels, strong ropes and corresponding pivots for achieving a full safety for operators and people around.
- The accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
- FIG. 1 is a side view of a preferred embodiment of the present invention;
- FIG. 2 is a side view of the present invention showing the fold-up action; and
- FIG. 3 is another side view of the present invention in the fold-up state.
- First of all, referring to FIGS. 1, 2 and3, a preferred embodiment of the present invention mainly includes a U-shaped
handrail 10, two supportingarms 20, aframe 30, afront support 40, a motorizedassembly 50 and arear treading plate 60. Theframe 30 has aplatform 31 the front and rear ends of which are fitted with a front andrear rollers treadmill walking belt 34 circles. Besides, therear roller 33 of theframe 30 is positioned onhorizontal parts 21 of the supportingarms 20 by means of afirst pivot 35. - The
motorized assembly 50 comprises amotor 51, abelt 52, a drivenwheel 53 and aprotection cover 54. Themotor 51 is fixed behind thehorizontal parts 21 of the supportingarms 20 by means of a fastening member. Thebelt 52 extend between apower output shaft 56 and the drivenwheel 53 while therear roller 33 is driven by the drivenwheel 53 for a rotational movement of thetreadmill walking belt 34. - Each end of the U-shaped
handrail 10 is provided with arope wheel 11 whoseshaft 12 is pivotably mounted on theextension part 22 at the top of each of the supportingarms 20. Thereafter, astrong rope 70 is fixed at one side of therope wheel 11 and pulled downward to thebottom 36 of theframe 30. When the U-shapedhandrail 10 is raised and turned around theshaft 12, therope wheel 11 is also rotated to pull thestrong rope 70 upward. Thereafter, theframe 30 is raised up to the top by means that therear roller 33 is turned around thefirst pivot 35. - Based on the above-mentioned components, the
frame 30 can be folded up for storage or unfolded for exercise operation only by moving the U-shapedhandrail 10. Meanwhile, when the U-shapedhandrail 10 is moved up to the top (see FIG. 3), thehandrail 10 is considerably turned to the other side of theframe 30 in a hung state at a locked angle. Therefore, theframe 30 won't be unexpectedly collapsed even in case of being moved. Theframe 30 can only be lowered by moving the U-shapedhandrail 10 in proper operation steps so that the safety is more ensured. - In order to facilitate the movement of the
strong rope 70, a plurality of locatingrolls 71 are disposed on the supportingarms 20. This belongs to prior art so that further descriptions won't be given. - Many changes and modifications in the above-described embodiment of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claim.
Claims (3)
1. A rope type folding mechanism for an exercise treadmill comprising a coupling mechanism between a U-shaped handrail and a walking frame so that when said handrail is rotated in preset direction, said frame is folded up to the folding top to complete the folding up action.
2. A folding mechanism for an exercise treadmill comprising a U-shaped handrail, two supporting arms, a frame, a front support, a motorized assembly and a rear treading plate;
wherein the improvement is characterized by:
said frame having a platform the front and rear ends of which are fitted with a front and rear rollers between which a treadmill walking belt circles, said rear roller of said frame being positioned on horizontal parts of said supporting arms by means of a first pivot;
said motorized assembly having a motor, a belt, a driven wheel and a protection cover, said motor being fixed behind said horizontal parts of said supporting arms by means of a fastening member, said belt extending between a power output shaft and said driven wheel while said rear roller is driven by said driven wheel for a rotational movement of said treadmill walking belt; and
each end of said U-shaped handrail being provided with a rope wheel whose shaft is pivotably mounted on said extension part at the top of each of said supporting arms; a strong rope being thereafter fixed at one side of said rope wheel and pulled downward to said bottom of said frame so that, when said U-shaped handrail is raised and turned around said shaft, said rope wheel is also rotated to pull said strong rope upward while said frame is raised up to the top by means that said rear roller is turned around said first pivot.
3. A folding mechanism for an exercise treadmill as recited in claim 2 , wherein said strong rope can be substituted by any equivalent components.
