The rail portion 550 and the rotary unit 560 are both installed in the housing case 17.

Referring to fig. 4, a rail portion 550 rotatable with respect to the housing case 17; and a rotation unit 560 rotatably supporting the rail part 550.

Referring to fig. 3 and 4, the rotating unit 560 includes at least a first rotating member 561 inside the housing 17 and a plurality of second rotating members 563 disposed inside the housing 17, and the diameter of the plurality of second rotating members 563 is smaller than that of the first rotating member 561.

The second rotating member 563 may be arranged in a curve in the upper portion of the housing case 17. The curve may be concave in the middle. The second rotating member 563 may be a ball bearing for rotating the belt 552 of the rail portion 550 described below.

Referring to fig. 4, the rail portion 550 may include several slats 551. The slats 551 are arranged close to each other in the rotational direction of the rail portion 550. Each of the slats 551 extends in a direction (e.g., X-direction) perpendicular to the rotational direction of the rail portion 550.

Referring to fig. 4, the slats 551 are connected to each other by a connecting member (e.g., a belt 552). The slats 551 connected by the strap 552 form a closed loop.

Referring to fig. 4, when the user 21 performs a foot motion on the rail portion 550, a force to move the rail portion 550 toward the rear is applied to the rail portion 550. As described above, since the rail portion 550 is rotatably supported by the first rotating members 561 respectively located in the front and rear portions and the second rotating members 563 arranged between the first rotating members 561, the rail portion 550 is rotated by the foot movement of the user 21.

Referring to fig. 3 and 4, in the above-described extension platform 5, the rail part 550 is rotated fast when the user 21 runs fast and the rail part 550 is rotated slowly when the user 21 runs slowly. When the user 21 stops, the rail portion 550 stops.

Referring to fig. 4, for example, the top area of the rail portion 550 may include a front area 5511, a reference area 5512, and a rear area 5555. The slope of each of the front and rear regions 5511, 5555 may increase away from the reference region 5512.

Referring to fig. 3 and 4, when the user 21 steps on the front area 5511, the force applied to the rail portion 550 by the user 21 increases, and thus, the rotation speed of the rail portion 550 also increases. When the user 21 steps on the rear area 5555, a force is applied to the rail portion 550 in a direction opposite to the rotation direction of the rail portion 550, and therefore, the rotation speed of the rail portion 550 is reduced.

Referring to fig. 3 and 4, as described above, the user 21 exercises on the track part 550 rotating according to the running speed of the user 21, thereby autonomously controlling the speed without additional operations. Therefore, the user 21 can exercise more actively.

Referring to fig. 3 and 4, since the rail part 550 is not rotated by the motor but by the movement of the foot of the user 21, the maximum speed of the rail part 550 and the rotational smoothness of the rail part 550 vary with the rotational resistance of the rail part 550. Here, the rotation resistance of the rail portion 550 is defined as a force acting in a direction opposite to the rotation direction of the rail portion 550 in the process of rotating the rail portion 550 by the foot motion of the user 21.

Referring to fig. 4, when the rotation resistance of the rail portion 550 increases, the maximum rotation speed of the rail portion 550 decreases and the rotation of the rail portion 550 may not be smooth at a high speed.

Referring to fig. 3 and 4, in this regard, the extension platform 5 may be designed such that the rotational resistance of the rail portion 550 is low. For example, the extension platform 5 may be designed such that the rotational resistance of the rail portion 550 is equal to or less than 2.0 kgf. More desirably, the extension platform 5 may be designed such that the rotational resistance of the rail portion 550 is equal to or less than 1.0 kgf. Therefore, the maximum rotation speed of the rail portion 550 of the extension platform 5 is increased, and the rail portion 550 can be smoothly rotated at a high speed.

Referring to fig. 3 and 4, however, when the rotation resistance of the rail portion 550 is low in all speed ranges, the rail portion 550 may slip or unintentionally rotate rapidly at a low speed. Therefore, the user 21 may feel uncomfortable when the user 21 starts exercising on the extension platform 5 or performs exercising at a low speed.

Referring to fig. 3 and 4, in this regard, an extension platform 5 is provided which gives a sense of stability to the user 21 by increasing the rotational resistance of the rail portion 550 at low speeds and gives a sense of naturalness of movement to the user 21 by decreasing the rotational resistance of the rail portion 550 at high speeds.

Referring to fig. 3 and 4, the extension platform 5 further includes: a detector configured to detect a rotational speed of the track part 550; and a resistance controller controlling a rotational resistance of the rail portion 550.

Referring to fig. 4, in order to detect the rotation speed of the track part 550, the detector may detect the rotation speed of the track part 550 itself or detect the rotation speed of the rotation unit 560 rotated by the track part 550.

Referring to fig. 3 and 4, however, the detection principle of the detector is not limited to the above description, and various changes may be made as long as the rotation speed of the track part 550 can be detected. For example, it is apparent that the detector may detect the position of the user 21 and detect the rotational speed of the track portion 550.

Referring to fig. 4, the resistance controller controls the rotational resistance of the track part 550 in response to the rotational speed of the track part 550 detected by the detector. For example, as the rotational speed of the track portion 550 increases, the resistance controller may decrease the rotational resistance of the track portion 550.

Referring to fig. 4, in order to control the rotation resistance of the rail part 550, the resistance controller may apply a variable force Δ F to at least one of the rotation unit 560 and the rail part 550 in a direction opposite to the rotation direction of the rail part 550. The variable force Δ F may be an electric force or a magnetic force, but is not limited thereto. The variable force af may be a mechanical force.

Referring to fig. 4, for example, the resistance controller may vary a force Δ F applied to the rotating unit 560 in a direction opposite to the rotating direction of the rail part 550.

Referring to fig. 4, as the rotation speed of the track part 550 increases, the resistance controller may reduce the force applied to the rotation unit 560 on the condition that the speed is equal to or lower than the reference speed, and may remove the force applied to the rotation unit 560 on the condition that the speed is equal to or higher than the reference speed.

Referring to fig. 4, here, the reference speed may be a maximum walking speed of the user 21. For example, the reference speed may be equal to or less than 7 km/h. However, the reference speed is not limited thereto, and various changes may be made. For example, the reference speed may be a speed at which the user 21 starts walking, for example, 3km/h or less. In another example, the reference speed may be a maximum speed that the user 21 can achieve on the track section 550, for example, 30km/h or less.

Referring to fig. 4, as the rotation speed of the track part 550 increases, the resistance controller may reduce the rotation resistance of the track part 550 under the condition that the speed is equal to or lower than the reference speed, and may maintain the rotation resistance of the track part 550 at the minimum rotation resistance "min" under the condition that the speed is equal to or higher than the reference speed.

Referring to fig. 4, the minimum rotational resistance "min" of the rail portion 550, which occurs when there is no force Δ F applied by the resistance controller in the opposite direction of the rotational direction of the rail portion 550, may be the rotational resistance of the rail portion 550. The minimum rotational resistance "min" of the rail portion 550 may be equal to or less than 2.0 kgf. Desirably, the minimum rotational resistance "min" of the rail portion 550 may be equal to or less than 1.0 kgf.

Referring to fig. 4, when the rotation speed of the rail part 550 is low, for example, when the user 21 starts walking on the rail part 550, the resistance controller applies a force Δ F greater than a certain level to the rotation unit 560 in the opposite direction of the rotation direction R of the rail part 550. Therefore, the rotation resistance of the rail portion 550 is greater than the minimum rotation resistance "min".

Referring to fig. 4, when the rotational speed of the track portion 550 is high, for example, when the user 21 runs on the track portion 550, the resistance controller removes the force Δ F applied to the rotation unit 560 in the opposite direction of the rotational direction R of the track portion 550. Accordingly, the rotation resistance of the rail portion 550 may be the minimum rotation resistance "min".

Referring to fig. 4, as described above, when the rail portion 550 is rotated at a low speed, a rotation resistance greater than a certain level is applied to the rail portion 550, and therefore, the user 21 can release the uncomfortable feeling that may be caused by the slip of the rail portion 550 at a low speed. In addition, when the rail part 550 is rotated at a high speed, the rotational resistance applied to the rail part 550 is minimized, and thus, the rail part 550 can be smoothly rotated at a high speed.

In addition, the mode of reducing the rotational resistance of the rail portion 550 using the resistance controller may be various.

Referring to fig. 4, in an embodiment, the resistance controller may continuously decrease the rotational resistance of the track part 550 according to the detected increase in the rotational speed of the track part 550. The resistance controller may linearly reduce the rotation resistance of the rail part 550 under the condition that the speed is equal to or lower than the reference speed.

Referring to fig. 4, the resistance controller may non-linearly reduce the rotation resistance of the rail part 550 under the condition that the speed is equal to or lower than the reference speed.

Referring to fig. 4, in another embodiment, the resistance controller may discontinuously decrease the rotational resistance of the track part 550 according to the detected increase in the rotational speed of the track part 550. The resistance controller may stepwise reduce the rotation resistance of the rail portion 550 under the condition that the speed is equal to or lower than the reference speed.

By arranging the extension platform 5, because the extension platform 5 is not driven by power, when the user 21 wants to stop exercising, the user can directly retreat to the extension platform 5 to safely stop exercising, thereby improving the safety of the user 21 in using the treadmill, and on the other hand, the rotation unit 560 is arranged to rotatably support the track part 550, thereby providing another exercise mode of the unpowered treadmill, increasing the exercise diversity of the treadmill and achieving two purposes.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
