Definitions

  • the present invention relates to an electric treadmill, and more particularly, to a device which is provided with a plurality of fixed sensing lines. When the operator touches one of them, a command is given to accelerate, decelerate or stop the operation of the treadmill.
  • the second prior art describes that a detector is fitted to both sides of the tread base for detecting the position of the runner. After a central processing unit processes the detection parameters, a command is given to accelerate or decelerate the motor.
  • the central processing units of both prior arts are used to evaluate the detection parameters to obtain the exact position of the runner. Thereafter, a command is given to accelerate or decelerate the motor. Consequently, the motor reacts after the steps of the runner or the body displacement.
  • both prior arts can obtain more accurate parameters to give command for accelerating or decelerating the motor, this is the reason why difficulties are caused in programming and in cooperation with other components. Therefore, the production costs thereof are considerably increased and the price thereof is always kept in a high level.
  • It's another object of the present invention to provide an electric treadmill which can considerably reduce the production cost by means that a more simple and cheaper central processing unit is used to automatically accelerate and decelerate the motor.
  • the position of the operator will be changed in accordance with his running speed when he stands at the centre of the running belt.
  • the electric treadmill includes a tread base 10, a handrail 11, an electric console 12, a motor 13, a running belt 14 and a rear support 15.
  • the motor 13 brings a drive belt 16 into rotation which drives a front roller 17.
  • the running belt 14 is placed around the front and rear rollers 17, 18, thereby creating an endless rotation by means of the operation of the motor 13.
  • the tread base 10 neighbouring upon the running belt 14 is provided with a multiple accelerating sensing line 20, a basic accelerating sensing line 30 and a decelerating sensing line 40 three of which are arranged one after another.
  • a CPU located within the electric console 12 gives a command according to the sensing position to accelerate or decelerate the motor 13. Accordingly, an immediate control of the rotational speed of the running belt 14 is achieved.
  • the operation principle and method of the sensing lines 20, 30, 40 are shown in FIG. 2.
  • the sensing lines 20, 30, 40 are created by means that the sensing elements 21, 31, 41 (e.g. infrared rays, laser rays, radar waves, etc.) each send out a straight signal crossing through said tread base 10 (see dashed line in FIG. 2), respectively.
  • the sensing elements 21, 31, 41 e.g. infrared rays, laser rays, radar waves, etc.
  • CPU will immediately and automatically send out a command to perform the speed control of the motor 13.
  • an optimal position of the operator is at the centre of the running belt 14 when the running speed of the operator is equal to the rotational speed of the running belt.
  • the position of the runner is shifted forwards when the running speed of the operator is higher than the rotational speed of the running belt 14, thereby contacting with basic accelerating sensing line 30. Therefore, the motor 13 is accelerated according to the preset value.
  • the position of the runner is shifted more forwards when the running speed of the operator is still higher than the rotational speed of the running belt 14 after the first adjustment, thereby contacting the multiple accelerating sensing line 20.
  • the motor will be accelerated once again.
  • the motor 13 won't be accelerated only if the operator doesn't contact the sensing lines 20, 30 any more.
  • the central position of the running belt 14 stands for the normal exercise position, that is, the exercise state when the running speed and the speed of the running belt 14 are identical.
  • the sensing lines 20, 30, 40 are arranged based on the reference point of the normal exercise position.
  • the multiple accelerating sensing line 20 differs from the basic accelerating sensing line 30 by the running speed of the operator. That is, when the running speed is gradually increased, the motor 13 is correspondingly accelerated (at the basic acceleration). When the running speed is sharply increased, the motor 13 is correspondingly accelerated (at the multiple acceleration) to meet the exercise needs. Similarly, when the running speed is decreased, the motor 13 is correspondingly decelerated.
  • a sensing line 50 for stop can be disposed behind the decelerating sensing line 40.
  • CPU gives a command to stop the motor 13 immediately.
  • the sensing line 50 for stop (with the sensing element 51) can be individually fitted to any electric treadmill and replace the safety pin 19 for disconnection.
  • both safety devices can be used together for a double safety effect.
