1. Treadmill Embodiment 1

1 and 2, the treadmill 10 according to the first embodiment of the present invention includes a support plate 110; Rotating belt 120; First rotating roller 130; It includes; the second rotating roller 140 and the installation frame 150.

The support plate 110 supports the weight of a person.

Rotating belt 120 is rotated indefinitely wearing the support plate (110).

The first rotating roller 130 is disposed adjacent to the front end (FE) of the support plate 110 to help the endless rotation of the rotating belt 120.

The second rotating roller 140 is disposed adjacent to the rear end RE ″ of the supporting plate 110 to help the endless rotation of the rotating belt 120.

As shown in FIG. 1, the first rotating roller 130 and the second rotating roller 140 are disposed adjacent to both front and rear ends of the support plate 110, and the rotating belt 120 includes the first rotating roller 130 and the second rotating roller 140. The rotary roller 140 is installed to enable infinite rotation using the turning direction of the turning point.

Support plate 110 is an acceleration portion (110a); Braking portion 110b; And a conversion portion 110c.

Here, the acceleration portion 110a converts the user's weight into the rotational power of the rotation belt 120 provided in the treadmill 10 to accelerate the rotation belt 120. Acceleration portion (110a) is inclined to the height is lowered from the front end (FE) to the rear end (RE). Therefore, when the user steps on any point of the acceleration portion 110a, the weight of the user is converted into rotational power for rotating the rotating belt 120. The entire section of the acceleration portion (110a) is made of a flat shape and is provided so that the height is lowered toward the rear end (RE).

The braking portion 110b is located at the rear end RE of the acceleration portion 110a and converts the weight of the person into the braking force of the rotating belt 120 to brake the rotating belt 120.

The braking portion 110b may have a height that is slightly lowered from the front end FE ′ to the rear end RE ′ or may be parallel to the horizontal line.

Therefore, the braking part 110b converts the weight of the user into the friction force between the rotating belt 120 and the support plate 110 (heat loss, etc. are omitted), thereby reducing the rotational speed of the rotating belt 120. Here, the entire section of the braking portion 110b may be provided in a flat shape.

Here, the switching part 110c connects the rear end RE of the acceleration part 110a and the front end FE ′ of the braking part 110b. And the rotating belt 120 in the switching portion (110c) is switched from the acceleration portion (110a) to the braking portion (110b). And the entire section of the switching portion (110c) is made of a shape bent downward to have a curvature and is provided to be lowered toward the rear end (RE ').

Since the acceleration portion 110a, the switching portion 110c, and the braking portion 110b as described above are integrally connected, the rear end RE of the acceleration portion 110a and the front end FE ′ of the switching portion 110c are It is the same point, and the rear end RE 'of the switching part 110c and the front end FE' of the braking part 110b are the same point.

At this time, when the height of the rear end RE ′ of the braking portion 110b is increased, the braking portion 110b may convert the weight of the user into a reverse rotational force opposite to the rotational direction of the rotation belt 120. Therefore, the rotation speed of the rotating belt 120 in the braking portion (110b) can be decelerated faster. If it is limited to this example, the acceleration portion (110a) may be defined as a portion that converts the user's weight into the rotational power required for the rotation belt 120 to rotate in the forward direction, the braking portion (110b) is the weight of the user The rotating belt 120 may be defined as a part for converting the rotational force in the opposite direction to the direction in which the rotating belt 120 rotates or reducing the rotational speed of the rotating belt 120 by the frictional force. However, when the front end FE of the acceleration portion 110a is increased, the braking force of the brake portion 110b may be lowered. Therefore, in consideration of the fact that the acceleration portion 110a and the braking portion 110b are integrally connected and the installation angle of the support plate 110 can be changed, the acceleration portion 110a has the weight of the user rotating belt 120. Defining a portion to accelerate the rotational speed of the brake, the braking portion (110b) is preferably defined as a portion of the user's weight to reduce the rotational speed of the rotating belt (120).
