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.

In FIG. 1, the high knees exercise apparatus 100 includes a base 110, two slide rails 120a, 120b, a driving member 130, a linkage mechanism 140 and two magnetic resistance devices 150a, 150b.

In detail, the base 110 includes a bottom base 111, a first supporting base 112, a second supporting base 113 and a seat base 114. 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. FIG. 2 shows a schematic view of the linkage mechanism 140 of FIG. 1. In FIG. 2, the linkage mechanism 140 includes two first linkage rods 141a, 141b, two second linkage rods 142a, 142b and a rotatable axis 143. One end of each of the first linkage rods 141a, 141b is connected to each of the pivoting members 131a, 131b, so that the first linkage rods 141a, 141b are linked up with the pivoting members 131a, 131b respectively. One end of each of the second linkage rods 142a, 142b is pivotally connected to the other end of each of the first linkage rods 141a, 141b. The rotatable axis 143 pivotally connects the other ends of the two second linkage rods 142a, 142b to the first supporting base 112. By such arrangement, when the driving members 132a, 132b are driven, the linkage mechanism 140 can be linked up via the pivoting members 131a, 131b, and the linkage mechanism 140 leads the two driving members 132a, 132b slid reversely in response to each other.

In FIG. 3A, when one driving member 132a is slid from the first supporting base 112 to the second supporting base 113 along the slide rail 120a and is parallel to the ground which is the highest position of the driving member 132a, the other driving member 132b is perpendicular to the ground. In FIG. 3B, when the driving member 132a is slid from the second supporting base 113 to the first supporting base 112, the driving member 132b is moved from the first supporting base 112 to the second supporting base 113 along the slide rail 120b (in FIG. 3B, the driving member 132b just covered by the first supporting base 112). In FIG. 3C, when the driving member 132a is perpendicular to the ground, the driving member 132b is slid to the end of the slide rail 120b and is parallel to the ground. Therefore, the slide direction of the driving member 132a, 132b can be controlled by the linkage mechanism 140, so that the two driving member 132a, 132b slid reversely in response to each other.

In FIGS. 17A, 17B and 17C, the relative position between the magnets 853a and the conductive members 851a can be changed by driving the shift shaft 861 and the linking shaft 862 via the pedal 833a.

FIG. 18A is a three dimensional view of a high knees exercise apparatus 900 according to still another embodiment of the present disclosure. FIG. 18B shows a three dimensional view of a forcing mechanism 961 of the high knees exercise apparatus 900 of FIG. 18A. In FIGS. 18A and 18B, the resistance adjusting device of the high knees exercise apparatus 900 includes a forcing mechanism 961 and a controlling member 963, wherein the forcing mechanism 961 is connected to the slide rails 920a, 920b for adjusting an embedded position between the magnet bases 952 and the conductive member 951, and the controlling member 963 is connected to the forcing mechanism 961.

In detail, the forcing mechanism 961 includes a plurality of operating assemblies 964 and a plurality of linkage members 965, wherein each of the operating assemblies 964 is connected to and linked up with each other via each of the linkage members 965. In FIGS. 18A and 18B, the forcing mechanism 961 includes three operating assemblies 964 and two linkage members 965.

FIG. 19A and FIG. 19B are schematic views of two using states of the high knees exercise apparatus 900 of FIG. 18A. In FIG. 19A, the adjacent area of the magnets 953 and the conductive member 951 is largest, so that the high knees exercise apparatus 900 can provide the maximum of the magnetic resistance during driving. In FIG. 19B, when the user pulls the controlling member 963, one of the operating assemblies 964 is moved, and other operating assemblies 964 are linked up via the linkage members 965. Therefore, the slide rails 920a, 920b can be moved. The conductive members 951 disposed on the slide rail 920a can also be moved, that is, the relative position (adjacent area) between the surface of the magnets 953 in the magnet base 952 and the surface of the conductive member 951 can be changed, and the magnetic resistance is adjusted (decreased).

FIG. 20 is a side view of a high knees exercise apparatus 1000 according to further another embodiment of the present disclosure. In FIG. 19, the resistance adjusting device of the high knees exercise apparatus 1000 includes a forcing mechanism 1061 and a controlling member 1063, wherein the forcing mechanism 1061 is connected to the slide rails 1020a for adjusting an embedded position between the magnet bases 1052 and the conductive member 1051, and the controlling member 1063 is connected to the forcing mechanism 1061.

In detail, the forcing mechanism 1061 includes a forcing base 1066, a linkage member 1067, at least one operating rod 1068 and a restoring member 1069, wherein the linkage member 1067 is movably connected to the forcing base 1066, at least one operating rod 1068 and a restoring member 1069 are located in the forcing base 1066, and the linkage member 1067 is moved by at least one operating rod 1068 and a restoring member 1069 (such as a spring). The operating rod 1068 can be driven by electric device (such as motor) or non-electric device (calm wheel) for pushing or pulling the linkage member 1067 to move the slide rails 1020a. When the operating rod 1068 pushes the slide rails 1020a, the restoring member 1069 would be compressed. The restoring member 1069 can provide a restoring force for pulling the linkage member 1067 and the slide rails 1020a back. Therefore, the relative position between the surface of the magnets (not be labeled) in the magnet base 1052 and the surface of the conductive member 1051 which is disposed on the slide rails 1020a can be changed, and the magnetic resistance is adjusted.

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.
