Description of Related Art
Exercise apparatuses make raining day and limited ground no longer be problems of doing exercise. Therefore, exercise apparatuses are main priority for modern people who are always busy but want to keep in shape. It is well-known that walking and running are body exercise which not only can burn calories and firm muscles but also can enhance myocardial function and increase lung capacity. Accordingly, treadmills, steppers, and elliptical trainers are most common exercise apparatus compared to others on the present market. However, users barely lift their knees high when using those exercise apparatus and improvements of muscle strength and body shape are mostly concentrated on their calf only.
High knees exercise is usually taken as a component of warm-up exercise to get heart rate going and also can burn calories and firm muscles as walking and running. This exaggerated knee motion further provides an excellent workout for the knees, hips, lower body, lower abdomen, and lower back and can enhance body strength, speed, balance, and flexibility. But, no apparatus for executing high knees exercise has been developed nowadays.

The first supporting base 112 and the second supporting base 113 are disposed on the bottom base 111. That is, one end of each of the first supporting base 112 and the second supporting base 113 is connected to the bottom base 111. The seat base 114 is disposed on the other end of the first supporting base 112. The user sits on the seat base 114 and faces the second supporting base 113 during using the high knees exercise apparatus 100. Moreover, the base 110 can further includes a handle 115 connected to the second supporting base 113.
The slide rails 120a, 120b are disposed on the bottom base 111 of the base 110 and located on two sides of each of the first supporting base 112 and the second supporting base 113 respectively. Each of the slide rails 120a, 120b is arc-shaped which extend from the second supporting base 113 to the first supporting base 112.
The driving mechanism 130 includes two pivot members 131a, 131b, two driving members 132a, 132b and two pedals 133a, 133b (131b, 132b and 133b are not shown in FIG. 1). The two pivot members 131a, 131b are symmetrically and pivotally connected to two sides of the first supporting base 112 respectively. In each of the driving members 132a, 132b, one end of the driving member 132a is connected to the pivoting member 131a, the other end of the driving member 132a is slidably connected to the slide rail 120a. Therefore, the driving member 132a can be driven for swinging along the arc-shaped of the slide rail 120a. The pedal 133a is connected to the driving members 132a. (The relationships among 120b, 131b, 132b and 133b are the same with the relationships among 131a, 132a and 133a, and will not describe herein.)
The linkage mechanism 140 is linked up with the pivoting members 131a, 131b for leading the driving members 132a, 132b slid reversely in response to each other.

The angle adjusting mechanism 1460 includes two lifting mechanisms 1462, which are elevator motors. One end of each lifting mechanism 1462 is connected to the connecting member 1443, the other end of each lifting mechanism 1462 is connected to the driving lever 1420. The arrangement of the lifting mechanisms 1462 can adjust the balancing angle of the driving levers 1420. The elevator motor and the controlling way thereof is common knowledge in the art of the present disclosure, and will not describe detailed herein.
FIG. 29C is a schematic view of the exercise apparatus 1400 of FIG. 29A with the driving lever 1420 in a balancing angle 45 degrees. FIG. 29D is a schematic view of the exercise apparatus 1400 of FIG. 29A with the driving lever 1420 in a balancing angle 24 degrees. When the lifting mechanisms 1462 of the angle adjusting mechanism 1460 is not activated, the two driving levers 1420 are parallel to each other and there is the balancing angle being 45 degrees between each of the driving levers 1420 and a virtual line L which is vertical to the ground. When the lifting mechanisms 1462 of the angle adjusting mechanism 1460 is activated, the two driving levers 1420 are parallel to each other and there is the balancing angle being 24 degrees between each of the driving levers 1420 and the virtual line L which is vertical to the ground. Therefore, the exercise apparatus 1400 can provide various exercise modes for training different portions of muscle.
Moreover, according to other embodiment of the present disclosure, the balancing angle can also be adjusted by adjusting the arrangement of the linking device so as to link up the driving levers. The arrangement of the linking device also can be adjusted by the angle adjusting mechanism, and will not be stated again herein.
By such arrangement, the high knees exercise apparatus would not provide inertia during working, so that the security of the high knees exercise apparatus is enhanced.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present disclosure without departing from the scope or spirit of the disclosure. In view of the foregoing, it is intended that the present disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims.
