Description

  • The present invention relates to a treadmill having a lifting device, and more particularly, a device which has simple components and efficiently reduces the manufacturing and assembling costs.
  • 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, a well-known lifting device for a treadmill includes a motorized transmission assembly 61 on a base frame 60. A slide rail 62 is arranged at the both inner sides of the base frame 60 so that two supporting parts 64 with rollers 63 can slide in the slide rail 62 for a forward and backward movement. Consequently, a walking frame 65 thereof is pivotably connected to the top of the supporting parts 64.
  • In order to strengthen the supporting force of the supporting parts 64, an auxiliary supporting rod 66 has to be interposed between the top of the supporting parts 64 and the base frame 60, thereby causing the complexity of the whole components and increasing the assembly and component costs.
  • US 6,325,745 discloses a foldable jogging machine comprising a support device and a linear actuator. The support device is mounted on the base such that the ends of left and right support rods are slidably received in a slotted rail of a base of the jogging machine. The linear actuator is fastened with the trotting platform in such a way that an expandable rod of the linear actuator is fastened pivotally with the support device. When the platform of the treadmill is slanted or elected the ends of the support rods slide within the rails.
  • (DE 201 10 451 U1) discloses a treadmill which can be slanted and erected. The treadmill comprises a telescopic rod which is pivotally connected to the frame structure. Two oscillating levers are pivotally connected to the base frame on their first ends respectively while the other ends are connected through a shaft. A pivot seat is provided on the shaft and receives the telescopic rod. At the end of the shaft two rollers are provided which are received by rails.
  • It is a primary object of the present invention to remove the above-mentioned drawbacks and to provide a treadmill with a lifting device 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 creates a pivot point. Accordingly, the potential drawbacks in using the conventional lifting device are removed.
  • This object has been achieved, according to the invention, by adopting the idea of making a treadmill having the characteristics indicated in claim 1. Further characteristics being set forth in the dependent claims.
  • 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 the present invention;
    • FIG. 2 is a schematic drawing in accordance with FIG. 1, showing the action thereof;
    • FIG. 3 is a schematic drawing of the preferred embodiment in accordance with FIG. 1 in the folding-up state of a base frame;
    • FIG. 4 is a perspective view of FIG. 3;
    • 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 in accordance with FIG. 5, showing the action thereof; and
    • FIG. 8 is a schematic drawing in accordance with FIG. 5 in the folding-up state of the base frame.
  • First of all, referring to FIG. 1 and 2, a preferred embodiment of the present invention includes an upright support 10 and a base frame 20. The upright support 10 is mounted at both sides of the front end of the base frame 20. A console 11 is disposed at the top of the upright support 10 while a horizontal leg 12 is connected to the bottom thereof. The base frame 20 has a first cross bar 21 on which a walking belt transmission assembly 30 is mounted while a front roller 22 is driven in motion by means of a transmission belt 32. A walking belt 24 is rotatable by means of the front roller 22 and a rear roller 23. A support wheel 25 is fitted to both bottom inner sides at the rear end of the base frame 20.
  • A lifting motor 41 with a locating transmission spindle 40 is pivotably connected to the front end of the base frame 20. A socket 42 is movable backward and forward by means of the rotational movement of the locating transmission spindle 40 while the other end of the socket 42 is pivotably connected to the top of an inverted-T-shaped cross bar 26 which extends beyond and through both sides of the base frame 20 and is connected with a pull rod 27, respectively. The other end of each of the pull rods 27 is pivotably connected to the upright support 10, thereby forming a pivot point 28. Accordingly, when the lifting motor 41 is actuated to let the socket 42 rotate by means of the rotational movement of the locating transmission spindle 40, the inverted-T-shaped cross bar 26 and the pull rod 27 will move in the desired direction. Therefore, the base frame 20 will be moved upward and downward on the pivot point 28.
  • As illustrated in FIGS 3 and 4, the base frame 20 can be folded up in a storage state by means of the pivoting effect of the pivot point 28. Thus, in order to stably support the base frame 20, a support bar 50 is pivotably connected at the lower side of the inverted-T-shaped cross bar 26 while the other end of the support bar 50 is pivotably connected to a support element 52. Thereafter, the axle of the support element 52 is pivotably secured to a second cross bar 29 of the base frame 20.
  • In brief, when the base frame 20 is folded up, the support element 51 constantly offers a proper supporting force in the horizontal direction to prevent it from an unexpected toppling.
