Abstract
Description
- 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.
- First of all, it is noted that the present invention is continuation-in-part of the US patent applications SER. No. 09//247,571 (now US 6,126,575) and 09/467,224 (now US 6,179,754) hereinafter called "the first prior art" and "the second prior art", respectively. It's described in the first prior art that an automatic roll-up rope is tied around the operator's body. In addition, a sensor is disposed to detect 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 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.
- In brief, 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. Although 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.
- Therefore, it is a primary object of the present invention to eliminate the above-mentioned drawbacks and to provide an electric treadmill 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. Thus, the operation procedure of the central processing unit is tremendously simplified to efficiently increase the ability of the instant reaction.
- 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 accomplishment of this and other objects of the invention will become apparent from the following description and its accompanying drawings of which:
- FIG. 1 is a perspective view of a preferred embodiment of the present invention; and
- FIG. 2 is a top view in accordance with FIG. 1, illustrating the position of the sensing lines.
-
- Before dealing with features of the present invention, the applicant has to give a brief description about the walking, jogging or running exercise on the electric treadmill in order to understand the basic control principles of the present invention.
- 1. The position of the runner is unchanged when the running speed of the operator is equal to the rotational speed of the running belt.
- 2. 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.
- 3. The position of the runner is shifted backwards when the running speed of the operator is lower than the rotational speed of the running belt.
-
- Accordingly, the position of the operator will be changed in accordance with his running speed when he stands at the centre of the running belt.
- As shown in FIGS. 1 and 2, the electric treadmill includes a
tread base 10, ahandrail 11, anelectric console 12, amotor 13, arunning belt 14 and arear support 15. Themotor 13 brings adrive belt 16 into rotation which drives afront roller 17. Therunning belt 14 is placed around the front andrear rollers motor 13. - Based on the central reference point, the
tread base 10 neighbouring upon therunning belt 14 is provided with a multiple acceleratingsensing line 20, a basic acceleratingsensing line 30 and a deceleratingsensing line 40 three of which are arranged one after another. When the runner touches the fixed sensing position by light wave or acoustic wave, a CPU located within theelectric console 12 gives a command according to the sensing position to accelerate or decelerate themotor 13. Accordingly, an immediate control of the rotational speed of therunning belt 14 is achieved. - The operation principle and method of the
sensing lines sensing lines sensing elements sensing lines motor 13. - Accordingly, 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 therunning belt 14, thereby contacting with basic acceleratingsensing line 30. Therefore, themotor 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 therunning belt 14 after the first adjustment, thereby contacting the multiple acceleratingsensing line 20. Thus, the motor will be accelerated once again. Themotor 13 won't be accelerated only if the operator doesn't contact thesensing lines running belt 14, the position of the runner is shifted backwards to contact with thedecelerating sensing line 40. Immediately, themotor 13 won't be decelerated only if the operator doesn't contact with thedecelerating sensing line 40 any more. - In brief, 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 therunning belt 14 are identical. Thesensing lines sensing line 20 differs from the basic acceleratingsensing line 30 by the running speed of the operator. That is, when the running speed is gradually increased, themotor 13 is correspondingly accelerated (at the basic acceleration). When the running speed is sharply increased, themotor 13 is correspondingly accelerated (at the multiple acceleration) to meet the exercise needs. Similarly, when the running speed is decreased, themotor 13 is correspondingly decelerated. - Besides, a
sensing line 50 for stop can be disposed behind the deceleratingsensing line 40. When the operator continues to be shifted forwards, thereby contacting with thesensing line 50 for stop, CPU gives a command to stop themotor 13 immediately. Thus, the safety of the operator can be more ensured. - In fact, the
sensing line 50 for stop (with the sensing element 51) can be individually fitted to any electric treadmill and replace thesafety pin 19 for disconnection. Of course, both safety devices (thesensing line 50 for stop and thesafety pin 19 for disconnection) can be used together for a double safety effect. - Many changes and modifications in the above-described embodiments of the invention can, of course, be carried out without departing from the scope thereof. Accordingly, to promote the progress in science and the useful arts, the invention is disclosed and is intended to be limited only by the scope of the appended claims.
