Description

Treadmill with front and rear inclination adjustment unit

The present invention relates to a treadmill having a front and rear inclination adjusting device, and more particularly to a treadmill in which the front and rear inclination of the tread platform can be adjusted and the height of the tread platform can be lowered.

Conventional treadmills can generally be raised or lowered so that the front end of the tread platform changes the slope of the tread platform and obtains a better locomotor effect. However, the front tip of the tread platform can simply be raised and cannot be tilted downwards. Thus, conventional treadmills could not provide downward tilted training.

6 shows an improved treadmill that can overcome the disadvantages of conventional treadmills. The linkage 8 is arranged below the tread platform 71 of the treadmill. The linkage 8 has an adapting board 81 which is pivotally arranged in the lower middle of the tread platform 71. The adapting board 81 is coupled with one end of the front link 82 and the rear link 83. The other end of the front link 82 is coupled with the front wheel bracket 84. The other end of the rear link 83 is coupled to the rear wheel bracket 85. The front wheel bracket 84 is driven by the driving means 86 to drive the front link 82, the rear link 83, the adapting board 81 and the rear wheel bracket 85. Thus, the front and rear ends of the tread platform 71 can be lifted to perform the tilted up and down tilted training.

In this structure, the limiting lever 73 must be installed between the tread platform 71 and the base sheet 72 to achieve a limiting effect on the tread platform 71. However, both the position and height of the limit lever 73 and the adapting board 81 will result in the height of the tread platform 71 rising. Thus, the tread platform 71 is spaced apart from the ground by a considerable distance. This makes it more dangerous to exercise on the tread platform 71.

Accordingly, a first object of the present invention is to provide a treadmill having a front and rear tilt adjusting device. The treadmill according to the present invention includes a base sheet, a tread platform and a tilt adjusting device.

The base sheet has two support arms each extending upwardly from both sides thereof. The front tip of the tread platform is mounted between two support arms of the base sheet. The tread platform is looped by one tread belt. The bottom of the rear end of the tread platform is pivotally connected to one end of the caster rack to which the tilt adjusting device is pivotally connected.

The inclination control device includes two symmetric lifting members and an elastic material rod. Each elevating member has a first tip and a second tip. The first leading end of the elevating member is pivotally connected to the inner surface of the lower end of the supporting arms, respectively. The second leading end of the elevating member is pivotally connected to both side surfaces of the front end of the tread platform, respectively. The first tip is disposed in front of the second tip. The transverse beam is firmly attached to the middle of the elevating members, connecting the elevating members. One end of the elastic material rod is pivotally connected to the transverse beam. The other end of the telescopic rod is pivotally connected to the caster rack below the bottom of the rear end of the tread platform. There is no need to leave a space under the tread platform for the restriction levers and the adapting board. In addition, the first leading end of the elevating members is pivotally connected with the supporting arms adjacent the bottom of the base sheet. In addition, the caster rack can be folded and positioned below the bottom of the tread platform. As a result, the height of the tread platform from the ground is effectively reduced, so that the tread platform 2 is closer to the bottom.

Still another object of the present invention is to provide the treadmill having a front and rear tilt adjusting device. The elastic material rod can be driven to swing the lifting members and the caster rack, it is possible to adjust the height of the front end and the rear end of the tread platform. Thus, the tread platform can form an up gradient of high tip and low back end and a down gradient of low tip and high back end. As a result, the slope of the tread platform is more variable, resulting in different training effects.

The present invention can be better understood through the following description and the accompanying drawings.

1 to 3, the treadmill of the present invention includes a base sheet 1, a tread platform 2, and an inclination adjusting device 3.

The base sheet 1 has two side bars 11 on the right side and the left side. From the front end of the side bars 11 two support arms 12 extend upwards, respectively. On the upper end of each support arm 12, a rail 13 is installed to be grasped by a user. A control panel 14 is installed between the two rails 13 so that the user can adjust the running speed and the inclination of the tread platform 2. The rear end of the side bar 11 is pivotally connected to one end of the auxiliary rod 15. The other end of the secondary rod 15 is pivotally connected to each side of the middle of the tread platform 2. In this embodiment, the auxiliary rod 15 is a pneumatic rod to assist in folding the treadmill.

The tip of the tread platform 2 is mounted between two support arms 12. The tread platform 2 is looped by a tread belt 21 driven by a motor (not shown) to circulate in rotation. Pivot holes 22 are drilled on both side surfaces of the tip of the tread platform 2. The rear end of the tread platform 2 is pivotally connected to one end of the caster rack 23. The caster rack 23 is pivotally connected to the inclination control device (3). Two casters 231 are pivotally connected to both side surfaces of the other end of the caster rack 23. In addition, an anti-collision cushion 24 is disposed below the tread platform 2 in front of the caster rack 23.

The inclination control device (3) is provided with two lifting members 31 and the elastic sewing material 32 symmetrical. Each elevating member 31 has an upwardly extending first tip 311 and an upwardly extending second tip 312 having a predetermined angle. The first tip 311 of the elevating member 31 is pivotally connected to the lower inner surface of the support arm 12. The second tip 312 of the elevating member 31 is pivotally connected to the pivot hole 22 on each side of the tread platform 2. The elevating members 31 under the tread platform 2 are firmly bound to the transverse beam 33 and the intermediate members thereof are connected between the elevating members 31. A connecting sheet 331 is provided at the middle of the horizontal beam 33. The connecting sheet 331 has a connecting tip 332 extending in the same direction as the upwardly extending second tip 312 of the elevating member 31. Accordingly, the connecting tip 332 and the upwardly extending second tip 312 are disposed on the same side facing the upwardly extending first tip 311. One end of the elastic material rod 32 is pivotally connected to the connecting tip 332 of the connecting sheet 331. The other end of the elastic material rod 32 is pivotally connected to the caster rack 23 under the tread platform 2. The elastic material rod 32 is driven by the power source 321 to expand and contract. In this embodiment, the elastic material rod 32 is a threaded rod and the power source 321 is a lifting motor.

3 and 4 show the up / down operation of the tread platform 2. By the power source 321, the elastic material rod 32 is adjusted to stretch. At this time, the caster rack 23 is folded toward the tread platform 2 to lean against the anti-collision cushion 24. Thus, when exercising, the tread platform 2 is prevented from colliding with the caster rack 23. When the elastic material rod 32 is elastic, the angle formed between the upwardly extending second tip 312 of the elevating member 31 and the tread platform 2 is changed. The upwardly extending first tip 311 of the elevating member 31 is pivotally connected to the support arm 12 of the base sheet 1, whereby the elevating member 31 is pivotally connected to the tread platform 2. The upwardly extending second tips 312 are turned upward with respect to the upwardly extending first tips 311. Thus, the front end of the tread platform 2 is driven and raised, so that the inclination of the rising slope of the tread platform 2 above the base sheet 1 can be adjusted (see FIG. 4). Conversely, when the tread platform 2 is lowered, by the power source 321, the elastic sewing material 32 is adjusted to extend forward. At this time, the upwardly extending second ends 312 of the two elevating members 31 connected to the tread platform 2 by the axis are directed downward, so that the front end of the tread platform 2 is driven and lowered.

5 shows that the forward end of the tread platform 2 is tilted down for the descending slope training. When the elastic sewing rod 32 is extended to lower the front end of the tread platform 2 and contact the transverse beam 33 of the tilt adjusting device, the elevating members 31 are no longer rotated. The telescopic sewing 32 may be further extended to drive the caster rack 23 to face rearward. The caster rack 23 is pivotally connected to the tread platform 2, so that the rear end of the tread platform 2 is lifted by the length of the caster rack 23. Thus, the height of the rear end of the tread platform 2 is higher than the height of the front end of the tread platform 2 so as to form a descending slope.

The upwardly extending first tips 311 of the elevating members 31 pivotally connected to the support arms 12 and the upwardly extending second tips 312 of the lifting members 31 pivotally connected to the tread platform 2 Extend upwards towards the top surface of the tread platform 2. Furthermore, the connecting tip 332 and the upwardly extending second tip 312 are disposed on the same side facing the upwardly extending first tip 311. Accordingly, the elevating members 31 change an angle included between the upwardly extending second tip 312 and the tread platform 2 to raise or lower the tread platform 2. In contrast to the present invention, in the conventional treadmills, the front and rear ends of the tread platform are raised or lowered to form the rising and falling slopes. Thus, there is no need to leave a space to swing below the tread platform for the limiting lever and the adapting board. In addition, the upwardly extending first tip 311 of the elevating members 31 is pivotally connected to the support arms 12 adjacent to the lower end of the base sheet 1. In addition, the caster rack 23 can be folded and positioned below the bottom of the tread platform 2. As a result, the height of the tread platform from the ground is effectively reduced, so that the tread platform 2 is closer to the bottom.

Moreover, the caster rack 23 can be driven so that the elastic sewing rod 32 can stretch and adjust the height of the rear end of the tread platform 2, whereby the tread platform 2 has a low front end. And a descending slope with a high rear end. Therefore, the inclination of the tread platform 2 can be more variously modified to obtain different training effects.

The foregoing embodiments are only used to describe the present invention, and are not intended to be limited within the scope. Various modifications of the above embodiments can be made without departing from the spirit of the invention.

As described above, the treadmill according to the present invention can be adjusted to the front and rear inclination of the tread platform and lower the height of the tread platform close to the ground has the effect of more safe movement.
