Automatic Speed Control Apparatus for Treadmill and Control Method Thereof
First Claim
1. A speed control apparatus for a treadmill including a deck, a track belt of endlessly rotating on the upper and the bottom face of the deck, and a driving unit for driving the track belt comprising:
- at least one front load sensor in the front part of the track belt for measuring load transferred via the deck which supports the user on the track belt; and
at least one rear load sensor in the rear part of the track belt for measuring load transferred via the deck which supports the user on the track belt;
wherein the location of the user on the track belt is sensed as being more biasedly located at the front part, as the measured value by the front load sensor is larger than the measured value by the rear load sensor; and
wherein the location of the user on the track belt is sensed as being more biasedly located at the rear part, as the measured value by the rear load sensor is larger than the measured value by the front load sensor, and wherein the speed of the track belt is controlled in accordance with the location of the user on the track belt.

Abstract
The present invention provides an automatic speed control apparatus for a treadmill and the control method including a deck, a track belt of endlessly rotating on the upper and the bottom face of the deck, and a driving unit for driving unit for driving the track belt comprising: at least one front load sensor located in the front part of the track belt for measuring load from a user on the track belt; at least one rear load sensor located in the rear part of the track belt for measuring load from the user on the track belt, wherein the proceeding speed of the track belt is controlled based on the user'"'"'s location or movement on the track belt by comparing the measured values from the front load sensor and the rear load sensor and catching the user'"'"'s location based on the comparison therebetween, whereby the proceeding speed can be automatically controlled corresponding with the user'"'"'s running speed without the user'"'"'s direct operation.

5. A speed control apparatus for a treadmill including a deck, a track belt of endlessly rotating on the upper and the bottom face of the deck, and a driving unit for driving the track belt comprising:
-
at least one front strain gauge in the front part of the track belt for being deformed by the load transferred via the deck which supports the user on the track belt; and at least one rear strain gauge in the rear part of the track belt for being deformed by the load transferred via the deck which supports the user on the track belt; wherein the front strain gauge and the rear strain gauge comprises at least one wheatston bridge circuit;
wherein the location of the user on the track belt is sensed by the bridge voltage of the wheatston bridge; and
wherein the speed of the track belt is controlled in accordance with the location of the user on the track belt. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12)

13. A speed control apparatus for treadmill including a deck, a track belt of endlessly rotating on the upper and the bottom face of the deck, and a driving unit for driving the track belt comprising:
-
an accelerating area set at the front part on the track belt for accelerating the speed of the track belt when a user is located at the accelerating area; a decelerating area set at the rear part on the track belt for decelerating the speed of the track belt when the user is located at the decelerating area; at least one front load sensor in the front part of the track belt for measuring load transferred via the deck which supports the user on the track belt; and at least one rear load sensor in the rear part of the track belt for measuring load transferred via the deck which supports the user on the track belt; wherein the location of the user is sensed by comparing the measured values from the front load sensor and of the rear load sensor, and thus, the track belt is accelerated when the user is on the accelerating area and the track belt is decelerated when the user is on the decelerating area. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
