Treadmill with more efficient shock absorption and cushioning device

Abstract

A more efficient treadmill shock absorption and cushioning device (I) mainly consists of a frame and a running board with a plurality of shock-absorbing blocks between them. Each shock-absorbing block is a horizontally hollow ring with a fixing hole on its top and bottom sides. At least one spacer rib extends from the maximum horizontal diameter of the hollow ring and has a through hole. Both ends of the spacer rib are connected to the inner wall of the hollow ring, thus dividing the interior of the hollow ring into upper and lower spaces. In this way, when the user steps on the treadmill running board, the shock-absorbing blocks not only have better elastic recovery performance, giving the running board a better cushioning and shock absorption effect, but also prevent the shock-absorbing blocks from being over-compressed and damaged, thus giving the shock-absorbing blocks a longer service life.

Claims

1. A more efficient shock absorption and cushioning device for treadmills, comprising: A framework; Multiple support members are fixedly installed at intervals on both sides of the frame; The running board is made of composite wood board; Multiple shock absorbers are made of elastic plastic material and are in the form of a horizontal hollow ring. Each is fixed to the top of the support member with its bottom and together they push upwards against the bottom of the running board. The top and bottom sides of the hollow ring wall are each provided with a fixing hole, and at least one spacer rib is provided at the maximum horizontal diameter inside the hollow ring. The spacer rib is provided with a through hole and its two ends are connected to the inner ring wall of the hollow ring, so that the interior of the hollow ring is divided into upper and lower spaces.

2. The treadmill shock absorption and cushioning device with better efficiency as described in claim 1, wherein, The shock absorber is a perfectly circular hollow ring.

3. The treadmill shock absorption and cushioning device with better efficiency as described in claim 1, wherein, The shock absorber is an elliptical hollow ring.

4. The treadmill shock absorption and cushioning device with better efficiency as described in claim 1, wherein, The hollow ring body has two parallel spacer ribs inside.

5. A treadmill shock absorption and cushioning device with improved efficiency as described in claim 1, wherein, The bottom of the shock absorber is fixed to the top of the support member with a screw.

6. The treadmill shock absorption and cushioning device with improved efficiency as described in claim 1, wherein, The top of the shock absorber is screwed to the bottom of the running board with a screw and a U-shaped fixing plate with a screw hole.

7. A treadmill shock absorption and cushioning device with improved efficiency as described in claim 1, wherein, The thickness of the ring wall of the shock absorber, the thickness of the spacer rib, the outer diameter of the cross section, and the axial length are 3.5~6.5mm, 2.5~5.0mm, 25~45mm, and 20~40mm, respectively.

8. A treadmill shock absorption and cushioning device with improved efficiency as described in claim 1, wherein, At least one abutment is provided on the upper and lower sides of the spacer rib between it and the inner wall of the hollow ring body.

9. A treadmill shock absorption and cushioning device with improved efficiency as described in claim 8, wherein, One end of the support member is connected to the spacer rib.

10. A treadmill shock absorption and cushioning device with improved efficiency as described in claim 8, wherein, One end of the support is connected to the inner wall of the hollow ring.
