DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-4, a balance device in accordance with the preferred embodiment of the present invention comprises an adjusting seat 20, and a balance board 10 detachably mounted on the adjusting seat 20.

The adjusting seat 20 has a substantially cylindrical cross-sectional profile. The adjusting seat 20 has an open upper portion having an inside formed with a mounting hole 21 and a closed lower portion formed with a protruding rocking portion 22. The rocking portion 22 of the adjusting seat 20 is substantially dome-shaped and extends outwardly from the lower portion of the adjusting seat 20. The upper portion of the adjusting seat 20 has a peripheral wall formed with a plurality of elongated locking grooves 23, 24 and 25 each connected to the mounting hole 21. The locking grooves 23, 24 and 25 of the adjusting seat 20 have different lengths.

The balance board 10 has a bottom formed with a protruding block 11 detachably inserted into the mounting hole 21 of the adjusting seat 20 and a plurality of locking ribs 13 each detachably inserted into one of the locking grooves 23, 24 and 25 of the adjusting seat 20. The protruding block 11 of the balance board 10 has a bottom formed with a protruding rocking section 12. The rocking section 12 of the protruding block 11 of the balance board 10 is substantially dome-shaped and extends outwardly from the bottom of the protruding block 11 of the balance board 10. The protruding block 11 of the balance board 10 is located at a central portion of the balance board 10. The protruding block 11 of the balance board 10 protrudes outwardly from the locking ribs 13 and has a bottom located at height smaller than that of a bottom of each of the locking ribs 13. The locking ribs 13 of the balance board 10 are arranged on a periphery of the protruding block 11 to surround the protruding block 11 so as to reinforce the strength of the balance board 10. The locking ribs 13 of the balance board 10 protrude outwardly from the periphery of the protruding block 11 in a radiating manner. Each of the locking ribs 13 of the balance board 10 has the same shape and is located at the same height.

In operation, referring to FIGS. 3 and 4 with reference to FIGS. 1 and 2, when the balance board 10 is combined with the adjusting seat 20, the rocking portion 22 of the adjusting seat 20 is rested on the ground to perform a rocking movement so that a user can step on the balance board 10 to practice a balance skill or to achieve an amusement by rocking of the rocking portion 22 of the adjusting seat 20. Alternatively, when the adjusting seat 20 is detached from the balance board 10, the rocking section 12 of the protruding block 11 of the balance board 10 is rested on the ground to perform a rocking movement so that a user can step on the balance board 10 to practice a balance skill or to achieve an amusement by rocking of the rocking section 12 of the protruding block 11 of the balance board 10. In such a manner, a user can step on the balance board 10 to practice a balance skill or to achieve an amusement by rocking of the rocking portion 22 of the adjusting seat 20 or by rocking of the rocking section 12 of the protruding block 11 of the balance board 10 so as to enhance the versatility of the balance device.

As shown in FIGS. 1-4, each of the locking ribs 13 of the balance board 10 is inserted into the respective locking groove 25 of the adjusting seat 20.

As shown in FIGS. 5 and 6, each of the locking ribs 13 of the balance board 10 is inserted into the respective locking groove 23 of the adjusting seat 20.

In such a manner, the locking grooves 23, 24 and 25 of the adjusting seat 20 have different lengths so that when each of the locking ribs 13 of the balance board 10 is inserted into the respective locking groove 23, 24 or 25 of the adjusting seat 20, the balance board 10 is located at different heights relative to the adjusting seat 20 to facilitate a user practicing the balance skill at different heights.

As shown in FIG. 7, the rocking portion 22a of the adjusting seat 20a has a periphery formed with an irregular rim 26 so that the rocking portion 22a of the adjusting seat 20a is rocked in an irregular manner, thereby enhancing the amusement effect of the balance device. Preferably, the irregular rim 26 of the rocking portion 22a of the adjusting seat 20a has a lotus-shaped profile.

Accordingly, the height of the balance board 10 relative to the adjusting seat 20 is adjustable so that the balance board 10 is located at different heights to facilitate a user practicing the balance skill at different heights. In addition, a user can step on the balance board 10 to practice a balance skill or to achieve an amusement by rocking of the rocking portion 22 of the adjusting seat 20 when the balance board 10 is combined with the adjusting seat 20 or by rocking of the rocking section 12 of the protruding block 11 of the balance board 10 when the adjusting seat 20 is removed from the balance board 10 so as to enhance the versatility of the balance device.

Although the invention has been explained in relation to its preferred embodiment(s) as mentioned above, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the present invention. It is, therefore, contemplated that the appended claim or claims will cover such modifications and variations that fall within the true scope of the invention.
