Abstract

This present invention discloses a treadmill comprising a base, a platform, two rollers, an endless belt, and at least two assemblies, and therefore the user can adjust the location of the adjustable assembly relative to the platform for reducing impact of the platform and varying flexibility of the platform to meet the user'"'"'s demanding so as to prevent sports injury during operation period.

Claims

1. A treadmill comprising:

a base having a front portion and a rear portion;

a platform supported by the base;

a front roller and a rear roller respectively coupled to the front portion and the rear portion of the base;

an endless belt encompassed the platform and coupled to the front roller and the rear roller; and

at least two adjustable assemblies movably disposed between the base and the platform to reduce impact of the platform, each of the adjustable assemblies respectively located under the right side and left side of the platform capable of moving back and forth relative to the platform, wherein each of the adjustable assemblies comprises a first supporting member rotatably mounted therein.

2. The treadmill as claimed in claim 1, wherein each of the adjustable assemblies further comprises a second supporting member and a third supporting member respectively rotatably mounted therein, and the three supporting members arrange in an order of nonlinear geometry figure.

3. The treadmill as claimed in claim 2, wherein at least one of the supporting members contacts with one of the base and the platform.

4. The treadmill as claimed in claim 2, wherein each of the supporting members keeps a space with others.

5. The treadmill as claimed in claim 2, wherein at least one of the supporting members contacted with one of the base and the platform is composed of resilient material.

6. The treadmill as claimed in claim 2, wherein each of adjustable assemblies comprises an adjustable portion, a connecting portion, three supporting members disposed between the connecting portion and the adjustable portion and at least one connecting assembly associated with the adjustable portion, the connecting portion and the three supporting members, wherein a user can hold the adjustable portion for pushing the adjustable cushion assembly to move back and forth relative to the platform.

7. The treadmill as claimed in claim 1, wherein the treadmill comprises a driving device to drive the at least two adjustable assemblies to move back and forth relative to the platform.

8. A treadmill comprising:

a base having a front portion and a rear portion;

a platform supported by the base;

a front roller and a rear roller respectively coupled to the front portion and the rear portion of the base;

an endless belt encompassed the platform and coupled to the front roller and the rear roller; and

at least two adjustable assemblies movably disposed between the base and the platform to reduce impact of the platform, each of the adjustable assemblies respectively located under the right side and left side of the platform capable of moving back and forth relative to the platform, wherein each of adjustable assemblies comprises a first supporting member, a second supporting member, and a third supporting member rotatably mounted therein, and the three supporting members arrange in an order of nonlinear geometry figure.

9. The treadmill as claimed in claim 8, wherein at least one of the supporting members contacts with one of the base and the platform.

10. The treadmill as claimed in claim 8, wherein at least one of the supporting members contacted with one of the base and the platform is composed of resilient material.

11. The treadmill as claimed in claim 8, wherein each of the supporting members keeps a space with others.

12. The treadmill as claimed in claim 8, wherein each of adjustable assemblies comprises an adjustable portion, a connecting portion, three supporting members disposed between the connecting portion and the adjustable portion and at least one connecting assembly associated with the adjustable portion, the connecting portion and the three supporting members, wherein a user can hold the adjustable portion for pushing the adjustable cushion assembly to move back and forth relative to the platform.

13. The treadmill as claimed in claim 8, wherein the treadmill comprises a driving device to drive the adjustable cushion to move back and forth relative to the platform.

14. A treadmill comprising:

a base having a front portion and a rear portion;

a platform supported by the base;

a front roller and a rear roller respectively coupled to the front portion and the rear portion of the base;

an endless belt encompassed the platform and coupled to the front roller and the rear roller; and

at least two adjustable assemblies movably disposed between the base and the platform to reduce impact of the platform, each of the adjustable assemblies respectively located under the right side and left side of the platform capable of moving back and forth relative to the platform, wherein each of adjustable assemblies comprises a first supporting member, a second supporting member, and a third supporting member rotatably mounted therein, wherein the three supporting members arrange in an order of nonlinear geometry figure, and at least one of the three supporting members contacts with one of the base and the platform.

15. The treadmill as claimed in claim 14, wherein each of the supporting members keeps a space with others.

16. The treadmill as claimed in claim 14, wherein the first supporting member contacts with the platform, and the second and third supporting members respectively contacts with the base.
