Description

Cushioning treadmill

This creation is about a treadmill, and in particular, a buffer mechanism is provided on the treadmill to provide users with a reduction in the impact of the reaction force on the human body during a running exercise.

In recent years, treadmills have been widely used for walking or running aerobic exercise. They are not affected by the external environment and climate. They can be used in indoors with limited space for exercise. Even treadmills are used with other sensors. Can be used as the detection and treatment of human body.

The traditional treadmill mainly has two roller elements rotatably installed in the two ends of the base, and then the belt passes around the aforementioned roller elements, and is additionally arranged on the base on the two roller elements and serves as the upper position of the supporting belt. The motor directly or indirectly drives the roller element through the speed change mechanism to adjust the speed of the belt. However, the traditional treadmill is very rigid, and it will cause discomfort on the hard running surface for a long time and when running. Therefore, the traditional treadmill uses a shock absorption mechanism to reduce the discomfort of the feet.

In order to prevent the treadmill from occupying too much indoor horizontal space, related companies have developed many treadmills with a retractable mechanism, so that the base / running platform can be folded upwards, and the shock-absorbing mechanism is set at the relevant position of the folded , But it will cause The gravity of the base / running platform is excessively concentrated on the shock absorption mechanism, and those who use Urex (hard rubber) in the shock absorption mechanism will change the stress on the Urex because of the change in the position of use and the folded position. Direction, so that the strength of the original rubber into a radial tensile force from the original axial load, because the radial tensile force easily lead to the entire shape of the deformation and weaken the cushioning effect in use, in the long-term due to stress concentration will occur under the force (Hard rubber) ruptures, breaks and eventually damages, so the shock absorber of the folded type treadmill needs to routinely inspect and even replace the new rubber (hard rubber).

This creative treadmill with buffer effect is mainly coordinated by the mechanism of the buffer group, so that most components will not change the position of too many buffer groups with the folded state, especially the position of the elastic buffer block. Avoiding the defects caused by the stress concentration under the change of the axial pressure to the radial tension due to the change of position in the past.

In order to achieve the above-mentioned object and effect, a buffering treadmill is provided, which includes a base, a plurality of buffer groups and a running platform, wherein: the base has a fixed portion and a force receiving portion arranged at intervals; each of the plurality of buffer groups The elastic buffer block includes an elastic buffer block, a fixed base, a rotating base and a support plate. The elastic buffer block is disposed on the upper surface of the force receiving part, and the upper end of the elastic buffer block has a pressure surface. The fixed base is fixed. On the upper surface of the fixed portion; the rotating seat is fixed on the lower surface of a pivoting section at one end of the running platform, and the other end of the running platform is an abutting section; the supporting plate is pivoted on the fixing seat with two ends respectively And the rotation base, and the support plate has a force-bearing surface; the running platform rotates relative to the support plate with the rotation base, and holds the support The force-bearing surface of the board contacts the pressure-bearing surface of the elastic buffer block, so that the running platform can switch a folding position and a use position relative to the base.

Each of the plurality of buffer groups 2 includes an elastic buffer block 21, a fixed seat 22, a rotating seat 23, and a support plate 24; in this embodiment, two sets of buffer groups 2 are taken as an example.

The elastic buffer block 21 is disposed on the upper surface of the force receiving portion 12, and the upper end of the elastic buffer block 21 has a pressure receiving surface 211; the elastic buffer block 21 referred to herein They are cylindrical hollow and can withstand radial deformation under axial pressure, and can be restored after external pressure is removed or greatly reduced.

The fixing base 22 is fixed on the upper surface of the fixing portion 11.

The rotating base 23 is fixed to a lower surface of a pivoting section 31 at one end of the running platform 3, and the other end of the running platform 3 is an abutting section 32.

The support plate 24 is pivoted on the fixing base 22 and the rotation base 23 respectively at two ends, and the support plate 24 has a force receiving surface 241. The support plate 24 in this embodiment is a substantially flat plate-shaped member.

The running platform 3 is rotated with respect to the supporting plate 24 by the rotating base 23 and keeps the stressed surface 241 of the supporting plate 24 in contact with the pressing surface 211 of the elastic buffer block 21 so that the running platform 3 can be relative to the base 1 A folding position and a use position are switched; the running platform 3 in this embodiment generally has a running belt 33 that surrounds it, a driving component 34 that drives the running belt 33, and a control unit 35 that controls the driving component 34.
