Abstract
Description
- The present invention relates to 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 reading plate.
- The frame of the conventional treadmill (for example, the disclosed US 5674453, and 6033347) is designed to be foldable in order to reduce the occupied space and 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 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.
- The accomplishment of this and other objects of the invention is characterized by the features of the characterizing portion of claim 1.
- By these features an exercise treadmill is achieved whose frame can be folded or unfolded by moving the handrail. Therefore the using convenience and safety is ensured. Furthermore, the frame can be folded to the tip at an automatic locking position by means of components of connection rods, pull rods and corresponding pivots for achieving a full safety for operators and people around. One embodiment of the treadmill according to the invention will be described in the following description and its accompanying drawings of which:
- FIG. 1 is a top view of an embodiment of the present invention;
- FIG. 2 is a side view of the embodiment of the present invention;
- FIG. 3 is a side view of the embodiment of the present invention showing the action thereof; and
- FIG. 4 is another side view of the embodiment of the present invention showing the action thereof.
-
- First of all, referring to FIGS. 1 and 2, a preferred embodiment of the present invention mainly includes a
U-shaped handrail 10, two supportingarms 20, aframe 30, afront support 40, amotorized assembly 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. The belt 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 pivotably connected to avertical part 22 of two supportingarms 20 by means of asecond pivot 11. Aconnection rod 12 extends downwards from either side of theU-shaped handrail 10, and each of theconnection rod 12 is pivotally connected to apull rod 14 by means of athird pivot 13. Thereafter, the other end of each of thepull rods 14 is pivotably secured to the corresponding position of theframe 30 by means of afourth pivot 15. Therefore, when theU-shaped handrail 10 is raised and turned on thesecond pivot 11, theconnection rod 12 will also be moved to bring thepull rod 14 to shift upwards. Thereafter, theframe 30 is turned on thefirst pivot 35 to be raised to the top for completing the folding step of theframe 30. - Based on the above-mentioned components, as shown in FIG. 3 and 4, the
frame 30 can be folded for storage or unfolded for exercise operation only by moving theU-shaped handrail 10. Meanwhile, when theU-shaped handrail 10 is moved up to the top (see FIG. 4), theconnection rod 12 and thepull rod 14 will created a blocking angle at which theframe 30 won't be unexpectedly collapsed even in case of being moved. Theframe 30 can only be lowered by moving theU-shaped handrail 10 in proper operation steps so that the safety is more ensured. - 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.
