Abstract
The present invention relates to lifting device for a treadmill. A lifting motor with a locating transmission spindle is pivotably connected to the front end of the base frame. A socket is movable backward and forward by means of the rotational movement of the locating transmission spindle while the other end of the socket is pivotably connected to the top of an inverted-T-shaped cross bar which extends beyond both sides of the base frame and is connected with a pull rod, respectively. The other end of each of pull rod is pivotably connected to the upright support, thereby forming a pivot point. Accordingly, when the lifting motor is actuated to let the socket rotate by means of the rotational movement of the locating transmission spindle, the inverted-T-shaped cross bar and the pull rod will move in the desired direction. Therefore, the base frame will be moved upward and downward on the pivot point.
Description
- 1. Field of the Invention
- The present invention relates to a lifting device for a treadmill, and more particularly, to a device which has simple components and efficiently reduces the manufacturing and assembling costs.
- 2. Description of the Prior Art
- The lifting device of the treadmill is used to adjust the supporting angle of the base frame of the treadmill, that is, the walking slope. This device can be mechanically or electrically operated. The present invention belongs to an electric lifting device.
- Referring to FIGS. 5 through 8, the well-known lifting device for a treadmill includes a
motorized transmission assembly 61 on abase frame 60. Aslide rail 62 is arranged at the both inner sides of thebase frame 60 so that two supportingparts 64 withrollers 63 can slide in theslide rail 62 for a forward and backward movement. Consequently, thewalking frame 65 is pivotably connected to the top of the supportingparts 64. - In order to strengthen the supporting force of the supporting
parts 64, an auxiliary supportingrod 66 has to be interposed between the top of the supportingparts 64 and thebase frame 60, thereby causing the complexity of the whole components and increasing the assembly and component costs. - It is a primary object of the present invention to remove the above-mentioned drawbacks and to provide a lifting device for a treadmill which has a simple component unit while the same effect is achieved so that the economical effect and the assembly convenience are attainable. Meanwhile, the supporting force is easily controllable. In addition, an upright support together with a pull rod connected to the frame create a pivot point. Accordingly, the potential drawbacks in using the conventional lifting device are removed.
- 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 perspective view of an assembled preferred embodiment of the present invention;
- FIG. 2 is a side view of FIG. 1;
- FIG. 3 is a schematic drawing of the preferred embodiment in accordance with FIG. 1, showing the action thereof;
- FIG. 4 is a schematic drawing of the preferred embodiment in accordance with FIG. 1 in the folding-up state;
- FIG. 5 is a partial perspective view of a conventional lifting device;
- FIG. 6 is a side view of FIG. 5;
- FIG. 7 is a schematic drawing of the preferred embodiment in accordance with FIG. 5, showing the action thereof; and
- FIG. 8 is a schematic drawing of the preferred embodiment in accordance with FIG. 5 in the folding-up state.
- First of all, referring to FIGS. 1, 2 and3, a preferred embodiment of the present invention includes an
upright support 10 and abase frame 20. Theupright support 10 is mounted at both sides of the front end of thebase frame 20. Aconsole 11 is disposed at the top of theupright support 10 while ahorizontal leg 12 is connected to the bottom thereof. Thebase frame 20 has afirst cross bar 21 on which a walkingbelt transmission assembly 30 is mounted while afront roller 22 is driven in motion by means of atransmission belt 32. Awalking belt 24 is rotatable by means of thefront roller 22 and arear roller 23. Asupport wheel 25 is fitted to either bottom inner side at the rear end of thebase frame 20. - A
lifting motor 41 with a locatingtransmission spindle 40 is pivotably connected to the front end of thebase frame 20. Asocket 42 is movable backward and forward by means of the rotational movement of the locatingtransmission spindle 40 while the other end of thesocket 42 is pivotably connected to the top of an inverted-T-shaped cross bar 26 which extends beyond both sides of thebase frame 20 and is connected with apull rod 27, respectively. The other end of each of thepull rods 27 is pivotably connected to theupright support 10, thereby forming apivot point 28. Accordingly, when thelifting motor 41 is actuated to let thesocket 42 rotate by means of the rotational movement of the locatingtransmission spindle 40, the inverted-T-shaped cross bar 26 and thepull rod 27 will move in the desired direction. Therefore, thebase frame 20 will be moved upward and downward on thepivot point 28. - As illustrated in FIG. 4, the
base frame 20 can be folded up in a storage state by means of the pivoting effect of thepivot point 28. Thus, in order to stably support thebase frame 20, an inverted-L-shaped rod 50 is pivotably connected the lower side of thefirst cross bar 21 of thebase frame 20 while the other end of the inverted-L-shaped rod 50 is pivotably connected to anaxle 52 of asupport element 51. Thereafter, thesupport element 51 is secured to asecond cross bar 13 of thehorizontal leg 12 of theupright support 10. - In brief, when the
base frame 20 is folded up, thesupport element 51 constantly offers a proper supporting force in the horizontal direction to prevent it from an unexpected toppling. - 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 claims.
Claims (2)
1. A lifting device for a treadmill comprising: an upright support mounted at both sides of the front end of a base frame, a console being disposed at the top thereof while a horizontal leg is connected to the bottom thereof, and
