The base mechanism 1 includes a base 11 extending forward and backward, and two shafts 12 pivotally mounted on the base 11 in a left-right axial direction and spaced forward and backward. The base 11 includes two side frames 111 spaced apart from each other, each side frame 111 having a front end 113 and a rear end 112 opposite to each other. One of the rotating shafts 12 is rotatably pivoted between the two front ends 113 of the side frames 111, and the other is rotatably pivoted between the two rear ends 112 of the side frames 111. Since the base mechanism 1 is of many types and is not the main point of the improvement of the present invention, it will not be described in detail and the embodiment is not limited by the drawings.

The power mechanism 2 includes a motor body 21 mounted between the side frames 111 of the base 11, and a driving belt 22 sleeved on the motor body 21 and the rotating shaft 12 located at the rear end 112 of the side frame 111. The motor body 21 is used for driving the transmission belt 22, so that the transmission belt 22 drives the rotating shaft 12 to rotate.

The running belt assembly mechanism 3 is a flexible structure and includes two spaced caterpillar belt assemblies 31 respectively disposed on the left and right sides of the rotating shaft 12, and a running belt 32.

Referring to fig. 4 to 6, each track set 31 is adjacent to the respective side frame 111, and has a track 311, which is sleeved around the rotating shaft 12 (see fig. 1) to be driven to rotate, and a guide belt 312 integrally connected to the track 311 and having an inner surface 314. The track set 31 is a timing belt. The tread belt 32 is connected to the outer surface 315 of the track 311 and the belt 312 opposite to the inner surface 314, and is adapted to be stepped on by the user. The running belt 32 includes a plurality of running strips 321 connected to each other to form a circular belt, and the type of the running belt 32 is numerous and is not important to the improvement of the present invention, and thus, detailed description is omitted and the implementation is not limited to the drawings.

The idler wheel mechanisms 4 are respectively disposed on the left and right sides of the base 11, and include a bracket 41 mounted on the respective side frame 111 of the base 11, an arm frame 42 pivotally connected to the bracket 41, an idler wheel 43 pivotally connected to the arm frame 42, and an elastic device 44 disposed between the bracket 41 and the arm frame 42.

The bracket 41 includes a body 411 vertically connected to the bottom of the corresponding side frame 111, and a connecting portion 412 extending from the top side of the body 411 along the length direction of the corresponding side frame 111.

The arm support 42 includes a pivot portion 421 pivotally connected to the body portion 411 of the bracket 41, a force receiving portion 422 extending obliquely downward from the pivot portion 421 and pivotally connected to the elastic device 44, and a force applying portion 423 extending obliquely downward from the pivot portion 421 in a direction different from the extending direction of the force receiving portion 422 and pivotally connected to the idle pulley 43, such that the force receiving portion 422 and the force applying portion 423 of the arm support 42 are located on opposite sides of the pivot portion 421 and are in an inverted "V" shape.

The idler pulley 43 is rotatably pivoted to the force application portion 423 of the arm support 42, and includes a connecting rod 431 pivotally connected to the force application portion 423 of the arm support 42, and a wheel body 432 connected to the connecting rod 431. The wheel 432 has a wheel surface 433 contacting the inner surface 314 of the corresponding belt 312, and is capable of pressing against the inner surface 314. The tread 433 is smooth and has no gear teeth.

The elastic device 44 includes a linkage 441 connected to the connecting portion 412 of the stand and pivotally connected to the force-receiving portion 422 of the arm support 42, and a spring 442 sleeved on the linkage 441. The elastic device 44 applies an elastic force (as indicated by an arrow) to the force-receiving portion 422 of the arm 42 and pull the force-receiving portion toward the connecting portion 412 of the bracket 41.

Referring to fig. 1 and 6, when a user uses the treadmill and runs on the running belt set mechanism 3, the power mechanism 2 (see fig. 3) drives the rotating shaft 12 to rotate the running belt set mechanism 3 relative to the base 11, and the idle wheel 43 is also rolling supported on the guiding belt 312. When the running belt set mechanism 3 is loosened after long-term use and cannot be tightly looped around the rotating shaft 12 of the base mechanism 1, the elastic device 44 of the idler wheel mechanism 4 constantly provides an elastic force for pulling the force-receiving portion 422 of the bracket 41, so that the force-applying portion 423 of the arm support 42 swings and sinks downwards with the pivot portion 421 as a central point, and drives the idler wheel 43 to downwards support the inner surface 314 of the guide belt 312, thereby maintaining the predetermined tension of the running belt set mechanism 3 and further tightening the running belt set mechanism 3.

It should be noted that the number of the idler gear mechanisms 4 is not limited to two, and in other variations of the present embodiment, the number of the idler gear mechanisms 4 may be one, and the idler gear mechanisms 4 are disposed at the bottom of one of the side frames 111 of the base 11.

Referring to fig. 7, a second embodiment of the treadmill of the present invention is similar to the first embodiment, except that the second embodiment replaces the elastic device 44 of the first embodiment with an adjuster 45 (see fig. 6). More specifically, the adjuster 45 is a screw and is disposed through the connecting portion 412 of the bracket 41 and the force-receiving portion 422 of the arm support 42, so that the distance between the connecting portion 412 and the force-receiving portion 422 can be adjusted by screwing the adjuster 45. When the distance is reduced, the force-receiving portion 422 swings counterclockwise (as shown by the arrow) about the pivot portion 421 as the center point, so that the force-applying portion 423 sinks downward in the direction indicated by the arrow, and the idle wheel 43 is kept downward to support the running belt set mechanism 3.

Referring to fig. 8, a third embodiment of the treadmill of the present invention is similar to the first embodiment, except that the idler mechanism 4 does not include the arm 42 and the elastic device 44 (see fig. 6); in addition, the bracket 41 of the idler mechanism 4 has two spaced elongated slot surfaces 413. Each slot face 413 defines a through-going aperture 414 extending along the length of the holder 41. The idler 43 of the idler mechanism 4 includes a connecting rod 431 passing through the through hole 414 and capable of moving up and down relative to the side frame 111 of the base 11, and a wheel body 432 connected to the connecting rod 431 and contacting the inner surface 314 of the guide belt 312. The idler gear mechanism 4 further includes an adjuster 46 passing through the top of the bracket 41 and the connecting rod 431. More specifically, the adjuster 46 is a screw. The adjuster 46 adjusts the distance between the idler pulley 43 and the top end of the elongated slot 413, so that the idler pulley 43 can support the running belt set mechanism 3 downward, thereby maintaining a predetermined tension of the running belt set mechanism 3.

In conclusion, the idler mechanism 4 of the treadmill of the present invention can support the running belt set mechanism 3, so that the running belt set mechanism 3 can maintain the predetermined tension and tightly cover the rotating shaft 12 of the base mechanism 1, thereby avoiding the problem that the running belt set mechanism 3 is easily loosened from the base mechanism 1, and avoiding the vertical vibration and shaking caused by the loosening of the running belt set mechanism 3.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the claims and the description of the present invention are still within the scope of the present invention.
