Related Art

A common aerobic stepper is mainly composed of an elongated stepping board and two supporting legs fixed under two ends of a longer length of the elongated stepping board respectively. The elongated stepping board is supported uprightly by the height of the two supporting legs in order to form a stepping board resembling a stair. Users can perform aerobic exercise by stepping forward, backward, leftward, rightward, upward and downward in order to achieve the effects of legs and waist exercise.

A common balance board is disposed with a circular disc as a stepping board, and a downwardly protruded arc-shaped body is disposed under a center of the stepping board. When the arc-shaped body is pressed downward against the ground, a user's center of gravity is unbalanced due to the disposition of the arc-shaped body that causes swing movement in different directions. Therefore, the user's sense of equilibrium can be trained and effects of physical fitness can also be achieved.

Each of the above mentioned exercise equipment can only provide a single function for physical training. They are stand-alone equipment and can not replace each other. Therefore, users will need to buy them separately if they want the two different kinds of physical training. As a result, the economical burden on the users is increased and more space is also required for storing the equipment.

Both the first supporting leg 3 and the second supporting leg 4 have a horizontal top end (31, 41), a vertical plane side (32, 42) and an arc-shaped connecting side (33, 43).

The top end of the first supporting leg 3 is disposed with four positioning columns 34 for correspondingly inserting, connecting and positioning inside the four cylindrical positioning grooves 25 and 26 of the first positioning portion 21 or the second positioning portion 22. The four positioning columns 34 are used as first connecting portions 35. A top of the side 32 of the first supporting leg 3 has a first engaging groove 36 and a first engaging piece 37 disposed on a same plane. The first engaging groove 36 and the first engaging piece 37 together form a first engaging portion 38. At where a bottom of the side 32 and the arc-shaped connecting side 33 of the first supporting leg 3 join together forms a first fulcrum 39.

The top end of the second supporting leg 4 is disposed with four positioning columns 44 for correspondingly inserting, connecting and positioning inside the four cylindrical positioning grooves 27 and 28 of the third positioning portion 23 or the fourth positioning portion 24. The four positioning columns 44 are used as second connecting portions 45. A top of the side 42 of the second supporting leg 4 has a second engaging groove 46 and a second engaging piece 47 disposed on a same plane. The second engaging groove 46 and the second engaging piece 47 together form a second engaging portion 48. At where a bottom of the side 42 and the arc-shaped connecting side 43 of the second supporting leg 4 join together forms a second fulcrum 49. When the multi-functional rhythmic platform 1 is embodied, the first positioning portion 21, the second positioning portion 22, the third positioning portion 23 and the fourth positioning portion 24 are also four or a plurality of positioning columns respectively. The first connecting portions 35 and the second connecting portions 45 are also four or a plurality of positioning grooves respectively.

Thereby, when the first connecting portion 35 of the first supporting leg 3 is upwardly connected with the first positioning portion 21, and the second connecting portion 45 of the second supporting leg 4 is upwardly connected with the fourth positioning portion 24; the elongated stepping board 2 is supported uprightly to compose an aerobic stepper by using the first fulcrum 39 and the second fulcrum 49 disposed under the two ends of the longer length of the elongated stepping board 2 respectively. When the first supporting leg 3 and the second supporting leg 4 are turned 180 degrees on a same plane, the first connecting portion 35 of the first supporting leg 3 is upwardly connected with the second positioning portion 22, and the second connecting portion 45 of the second supporting leg 4 is upwardly connected with the third positioning portion 23; the second engaging groove 46 is engaged with the first engaging piece 37 correspondingly, and the second engaging piece 47 is engaged with the first engaging groove 36 correspondingly; the side 32 of the first supporting leg 3 and the side 42 of the second supporting leg 4 are adjacent to each other and disposed under a central position of the longer length of the elongated stepping board 2, and a common fulcrum is formed at the central position of the longer length of the elongated stepping board 2 in order to compose a balance board. When the multi-functional rhythmic platform 1 is embodied, the first supporting leg 3 and the second supporting leg 4 connected with each other as shown in FIG. 5 can also be used alone after being turned upside down.

Please refer to FIG. 6, which shows a second embodiment of the multi-functional rhythmic platform 1 of the present invention. The differences between the second embodiment and the first embodiment lie in: a first supporting rod 5 and a second supporting 6 are respectively disposed at the two ends of the longer length of the elongated stepping board 2; the first supporting rod 5 is connected with an end of a first elastic rope 51, and the second supporting rod 6 is connected with an end of a second elastic rope 61. Thereby, users can use the first elastic rope 51 and the second elastic rope 61 for stretching.

Please refer to FIGS. 7 to 9, which show a third embodiment of the multi-functional rhythmic platform 1 of the present invention. The differences between the third embodiment and the first and second embodiments lie in: the first supporting rod 5 and the second supporting rod 6 are movably positioned by two first positioning elements 7 and two second positioning elements 8 disposed at the two ends of the longer length of the elongated stepping board 2. The first supporting rod 5 and the second supporting rod 6 are dumbbells. The two first positioning elements 7 have a same size and are shaped correspondingly. The two second positioning elements 8 have a same size and are shaped correspondingly.

The combination of one of the first positioning elements 7 and the elongated stepping board 2 is used as an example hereunder for illustrating the combinations of the two first positioning elements 7, the two second positioning elements 8 and the elongated stepping board 2. A flat board 9 is disposed at one of the ends of the longer length of the elongated stepping board 2. Two first guiding portions 91 formed as elongated grooves are disposed on the flat board 9. A recess 92 is formed above the flat board 9, and the first positioning element 7 is positioned in the recess 92.

A semi-circular positioning groove 71 is formed at a side of the first positioning element 7 for positioning an end of the first supporting rod 5. Two protruded columns protruding downwardly corresponding to the first guiding portions 91 respectively are disposed on a bottom of the first positioning element 7. The protruded columns are used as second guiding portions 93. After bottoms of the first guiding portions 91 and the second guiding portions 93 are fixed by using a long plate 94, the long plate 94 and the bottom of the first positioning element 7 are loosely connected. Thereby, the first positioning element 7 moves horizontally relative to the elongated stepping board 2 for releasing the end of the first supporting rod 5. The bottom of the first positioning element 7 has an elastic pressing portion 95 that displaces upward and downward. Thereby, when the elastic pressing portion 95 is pressed against on the flat board 9, the first positioning element 7 is positioned on the flat board 9 of the elongated stepping board 2.

Therefore, the multi-functional rhythmic platform of the present invention has the following advantages:

1. As shown in FIGS. 10 and 11, the different combinations of the elongated stepping board and the two supporting legs of the present invention allow users to use the multi-functional rhythmic platform as both an aerobic stepper and a balance board for two kinds of physical training.
