Figure 1 is a side view of a treadmill according to an embodiment of the present invention, and Figure 2 is a top view of a treadmill according to an embodiment of the present invention.

Referring to FIGS. 1 and 2, the treadmill 100 disclosed in this specification includes a treadmill body 101 and a drive motor 110 provided therein, either of which is connected to the drive motor 110 and rotates forward. It may be configured to include a running belt 130 that rotates around the roller 120, the rear drive roller 121, the front drive roller 120, and the rear drive roller 121. In addition, a support 102 is connected to a part of the treadmill body 101, and a control panel 103 that can control the entire treadmill 100 and a control panel 103 that allows the user to place his or her hand on a part of the support 102. The handle rail 104 is connected. Since the running belt 130 is supported by the deck panel 140 inside the treadmill body 101, the user can exercise on the rotating running belt 130.

The illustrated components are not essential, and the treadmill 100 may be implemented with more components or fewer components.

The drive motor 110 is provided on one front side of the treadmill main body 101, the front drive roller 120 is rotatably installed at the front of the treadmill main body 101, and the rear drive roller 121 is installed on the treadmill main body 101. It is rotatably installed at the rear inside the main body 101. The drive motor 110 transmits rotational force to the front drive roller 120 through the drive belt 111 to rotate the running belt 130. In the embodiment of the present specification, the drive motor 110 is shown and explained as transmitting rotational force to the front drive roller 120 through the drive belt 111, but depending on the embodiment, the drive motor 110 is a drive belt ( The rotational force may be transmitted only to the rear driving roller 121 through 111), or the rotational force may be transmitted to both the front driving roller 120 and the rear driving roller 121 through another driving belt (not shown).

Grooves 125 are formed on the outer peripheral surfaces of the front drive roller 120 and the rear drive roller 121 in the direction of rotation at positions spaced a certain distance from the left and right ends.

In addition, a protrusion 135 is formed along the rotation direction of the running belt 130 at a position corresponding to the groove 125 on the surface of the running belt 130 in contact with the front drive roller 120 and the rear drive roller 121. It is done.

Therefore, when the front drive roller 120 and the rear drive roller 121 rotate due to the rotation of the drive motor 110, the protrusion 135 of the running belt 130 is in contact with the groove portion of the drive rollers 120 and 121. Since it is inserted into 125), the running belt 130 does not deviate from the designated position from the drive rollers 120 and 121.

FIG. 3 is an enlarged view of part A in FIG. 2, showing some components as a partial cutaway view, and FIG. 4 is a side view of the driving roller of a treadmill according to an embodiment of the present invention.

3 and 4, the front drive roller 120 is rotatably connected to the roller fixing shaft 122. A driving pulley 112 is fixed to one end of the front driving roller 120, and the rotational force of the driving motor 110 is generated by the rotation of the driving belt 111 connected to the driving pulley 112 to the front driving roller 120. is passed on. The tension of the drive belt 111 can be adjusted by manipulating the tension adjustment unit 113 connected to the roller fixing shaft 122.

A groove 125 is formed in the rotation direction of the front drive roller 120 at a position spaced a certain distance from one end of the front drive roller 120. The shape of one cross-section of the groove portion 125 may be triangular, or may be formed in the shape of an equilateral trapezoid where the length of the top of the groove is longer than the length of the bottom of the groove. Additionally, the shape of one cross section of the groove 125 may be rectangular.

In the embodiment of FIG. 3, the groove portion 125 formed at the left end of the front drive roller 120 is explained as an example, but the groove portion 125 is located at the right end of the front drive roller 120 and the rear drive roller 121. The same may be formed on the left and right ends, and two or more grooves may be formed on one driving roller as needed.

The protrusions 135 are formed in a line on the entire surface of the running belt 130 along the rotation direction of the running belt 130. The protrusions 135 may include a plurality of protrusions 136 having a certain length. You can. The transverse cross section of the protrusion 136 may have a shape corresponding to one cross section of the groove portion 125 or may have a shape accommodated in the groove portion 125. In the embodiment of FIG. 3, the transverse cross section of the protrusion 136 is configured to have a triangular cross section along the shape of the groove portion 125.

Additionally, the plurality of protrusions 136 may be formed to be spaced apart at regular intervals. The length of the projections 136 and the size of the gap between the projections 136 have a maximum value depending on the length of the diameter of the front and rear drive rollers 120 and 121, that is, the radius of curvature of the front and rear drive rollers 120 and 121. can be decided. This is because the running belt 130 rotates in close contact with the driving rollers 120 and 121, so that adjacent projections 136 do not collide with each other on the curved surfaces of the driving rollers 120 and 121. The distance between them must be determined, and if the length of the protrusion 136 is too large, a problem may occur where the running belt 130 is not in close contact with the driving rollers 120 and 121, or the running belt 130 may be damaged. This is because problems may arise.

Additionally, the protrusion 135 may be made of a flexible material so that its shape changes depending on the shape of the running belt 130 when the treadmill 100 is driven. That is, since the running belt 130 rotates in close contact with the outer peripheral surface of the front and rear drive rollers 120 and 121, when the running belt 130 changes to a curved surface by the drive rollers 120 and 121, the protrusion 135 The material must be ductile to avoid breakage.

Referring to FIG. 4, the protrusion 136 of the protrusion 135 is formed at a constant distance from neighboring protrusions, and its longitudinal cross-section is in the shape of an isosceles triangle with the length of the upper side being shorter than the length of the lower side.

FIG. 5 shows examples of various shapes of the protrusion 135 of the track 130. FIG. 5(a) shows the shape of the protrusion 136 remaining after removing the semicircle from the square shape, FIG. b) shows that the shape of the protrusion 136 is a triangle, Figure 5(c) shows that the shape of the protrusion 136 is a trapezoid, and Figure 5(d) shows that the shape of the protrusion 136 is a semicircle. do.
