Abstract

An elastic platform is provided a treadmill. The elastic platform includes a frame and a piece of fabric. The frame is connected to the treadmill. The piece of fabric is supported on the frame. The piece of fabric supports a section of a belt wound around two rollers of the treadmill.

Claims

1. An elastic platform for use in a treadmill, the elastic platform comprising:

a frame connected to the treadmill; and

a piece of fabric supported on the frame, wherein the piece of fabric supports a section of a belt wound around two rollers of the treadmill.

2. The elastic platform according to claim 1, wherein the piece of fabric is a piece of elastic fabric.

3. The elastic platform according to claim 2, wherein the frame includes two longitudinal beams and two transverse beams extending between the longitudinal beams.

4. The elastic platform according to claim 3, wherein the frame includes a reinforcing beam extending between the longitudinal beams.

5. The elastic platform according to claim 3, including transverse adjusting sets operable to adjust the distance between the longitudinal beams to adjust tension in the piece of elastic fabric.

6. The elastic platform according to claim 5, wherein each of the transverse adjusting sets includes:

a socket securely located in a related one of the transverse beams;

a nut non-rotationally located in a related one of the longitudinal beams; and

a threaded bolt abutted against the socket and engaged with the nut.

7. The elastic platform according to claim 6, including longitudinal adjusting sets for adjusting the distance between the transverse beams.

8. The elastic platform according to claim 7, wherein each of the longitudinal adjusting sets includes:

a threaded lining movably located in a related one of the longitudinal beams and connected to the nut of a related one of the transverse adjusting sets;

a cap secured to the related longitudinal beam; and

a threaded bolt inserted through the cap and engaged with the threaded lining.

9. The elastic platform according to claim 8, wherein each of the longitudinal beams includes two slots through which the threaded bolt of a related one of the transverse adjusting sets is inserted.

10. The elastic platform according to claim 2, wherein the frame includes two longitudinal beams and two transverse beams each including a first bent end connected to one of the longitudinal beams and a second bent end connected to the other longitudinal beams.

11. The elastic platform according to claim 10, including adjusting sets operable to adjust the distance between the longitudinal beams to adjust tension in the piece of elastic fabric.

12. The elastic platform according to claim 11, wherein each of the adjusting sets includes:

a socket secured to the second bent end of a related one of the transverse beams;

a nut located within and secured to one of the longitudinal beams; and

a threaded bolt engaged with the nut and abutted against the socket.

13. The elastic platform according to claim 12, including two covers for protectively covering the adjusting sets.

14. The elastic platform according to claim 13, wherein each of the covers includes a groove for receiving a related one of the longitudinal and recesses for receiving heads of the threaded bolts.

15. The elastic platform according to claim 1, including two rods inserted through two loops formed on the piece of fabric.
