Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a balancing exerciser, and more particularly to a balancing exerciser including an improved and simplified structure that may be easily and quickly manufactured with a reduced manufacturing procedure and cost and that may be easily transported or carried with the user and that may be easily operated by the user.

[0003] 2. Description of the Prior Art

[0004] Typical balancing exercisers comprise a disk or plate or foot support for supporting a user thereon, and for attempting to maintain the disk or plate or foot support in a horizontal position or status, or for allowing the user to conduct the balancing exercises or operations.

[0005] For example, U.S. Pat. No. 5,092,586 to Tuthill et al. discloses one of the typical disk balancing exercisers comprising a disk or plate or foot support with threaded hole in its center for threading or engaging with the threaded bolt or screw which includes a hemispherical shoe attached to the bottom portion thereof for pivotally engaging with a supporting surface or ground and for allowing the typical disk balancing exercisers to be operated to maintain the foot support in a horizontal position or status, and for conducting the balancing exercises or operations.

[0006] However, the threaded bolt or screw and the foot support may be inclined or tilted a lot relative to the supporting surface or ground, and the users, particularly the elders and the children may feel afraid and may not use or operate the typical disk balancing exercisers.

[0007] U.S. Pat. No. 4,749,180 to Boomer, U.S. Pat. No. 5,509,871 to Giovanni, and U.S. Pat. No. 5,904,636 to Chen disclose other typical mechanical surfboard simulators for training users in the operation or sport of surfing or balancing exercisers or operations and/or for conducting the balancing exercises or operations.

[0008] However, the typical mechanical surfboard simulators include a rather complicated structure that may not be easily manufactured and assembled by the manufacturing workers and that may not be easily carried and transported by the users and that may not be easily operated outdoors.

[0009] U.S. Pat. No. 7,635,325 to Chiang et al. discloses a further typical interactive training device comprising an operation unit including an immovable base, a movable plate, and a supporting member disposed between the immovable base and the movable plate.

[0010] However, the tilting operation or the inclination of the movable plate is limited by the supporting member that may not be easily twisted or inclined or tilted relative to the supporting surface or ground, and the movable plate may not freely pivoted or rotated relative to the immovable base to conduct the balancing exercises or operations.

[0011] The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional balancing exercisers.

SUMMARY OF THE INVENTION
