- With reference to
FIG. 1 toFIG. 7 , a resistance regulating balance board according to a first embodiment of the invention comprises adisc body 1, asemispherical base 2, a regulatingrotary lid 3, aresistance member 4, anelastic component 5 and alocking member 6. Thedisc body 1 has an upperconcave cavity 11 thereon to accept the regulatingrotary lid 3. A bottom surface of thedisc body 1 includes a firstlower arc cavity 12 for accepting thesemispherical base 2. A throughhole 13 is disposed between the upperconcave cavity 11 and the firstlower arc cavity 12. The throughhole 13 is cross-shaped so that alodging portion 421 of ahollow tube body 42 of theresistance member 4 can engage with thethrough hole 13. An upper surface of thedisc body 1 includes a plurality ofbumps 14 andgrooves 15 to provide an anti-skid surface relative to the feet of a user. The lower surface of thedisc body 1 includes a plurality ofrib sheets 15. Thedisc body 1 thus has the same structural strength but uses fewer materials. - A
top arc surface 211 along an upper surface of thesemispherical base 2 can be exactly inserted into the firstlower arc cavity 12 of thedisc body 1. A bottom end of thesemispherical base 2 includes abottom board 22 that radially extends beyond the semispherical surface oftop arc surface 211. An external diameter of thebottom board 22 is larger than the external diameter of thetop arc surface 211 of thesemispherical base 2 to provide the whole a steady and supportive effect for the embodiment balance board. A central region of thesemispherical base 2 includes a secondlower arc cavity 23 for accepting theresistance member 4, and apivot hole 24 having a larger movable space (e.g., sufficient to allow desired angular movement of hollow tube body 42) extends through the secondlower arc cavity 23. Thepivot hole 24 is designed as an inverted cone, having a diameter that is greater at thetop arc surface 211 than at thelower arc cavity 23. Thetop arc surface 211 of thesemispherical base 2 includes a circular arrangement ofseveral trenches 222 angularly spaced at equal intervals. Lubricant can be filled into thetrenches 222 to provide a lubrication effect for the firstlower arc cavity 12 of thedisc body 1 and thetop arc surface 211 of thesemispherical base 2 when in use, thereby increasing the service life of the balance board according to an embodiment of the invention. - An inner surface of the central portion of a
lid body 31 of the regulatingrotary lid 3 includes alodging hole 311 having hexagonal shape to accept a hexagonal head at one end of ascrew rod 32 to combine and fit thescrew rod 32 with thelid body 31. Of course, thescrew rod 32 can also be integrally combined and fastened to thelodging hole 311 of the regulatingrotary lid 3 by means of in-mold buried molding to allow thelid body 31 and thescrew rod 32 to be permanently coupled together. - The
resistance member 4 has ahollow tube body 42 extending from a top surface of asemispherical portion 41. A top of thehollow body 42 includes alodging portion 421 to allow thehollow tube body 42 to pass through thepivot hole 24 of thesemispherical base 2 such that thelodging portion 421 can be lodged into the throughhole 13 using the cross shape of thedisc body 1, while thearc surface 43 of thesemispherical portion 42 and the secondlower arc cavity 23 of thesemispherical base 2 are set together as a correspondingly inserted structure. At the same time, the hole diameter of thepivot hole 24 is greater that the tube diameter of thehollow tube body 42 to allow thehollow tube body 42 to radially move within thepivot hole 24. The central region of theresistance member 4 includes a containingchamber 44 composed of afirst chamber 441 and asecond chamber 442. Thefirst chamber 441 is disposed inside thehollow tube body 42 while thesecond chamber 442 is connected with and below thefirst chamber 441 to form a hexagonal structure for accepting alocking member 6 having a hexagonal shape so as to be fixed and incapable of rotation while thelocking member 6 is disposed therein so that thelocking member 6 and thescrew rod 32 are incorporated to lock thedisc body 1, thesemispherical base 2 and theresistance member 4 together. In other words, one end of thescrew rod 32 passes through thefirst chamber 441 from the throughhole 13 of thedisc body 1 to lock with thelocking member 6 in thesecond chamber 442, thereby achieving the desired fastening purpose. - It should be noted that when locking the
screw rod 32 with thelocking member 6, theresistance member 4 is pressed by the secondlower arc cavity 23 of thesemispherical base 2 to generate different friction coefficients so as to create more or less motion resistance. Its resistance generation may have two modes. One type is that theresistance member 4 is made of a relatively softer material. When thescrew rod 32 couples with thelocking member 6 and fastens theresistance member 4 in thesemispherical base 2, thescrew rod 32 can be rotated by the regulatingrotary lid 3 to regulate the degree of tightness. The friction coefficient between theresistance member 4 and the secondlower arc cavity 23 is thus controlled to regulate the magnitude of the movement resistance force (as shown inFIG. 7 ). - The second mode is that an
elastic component 5 is disposed in thesecond chamber 442, and thescrew rod 32 passes through theelastic component 5. When thescrew rod 32 is screwed into thelocking member 6, thescrew rod 32 is rotated by the regulatingrotary lid 3 to drive theelastic component 5 to press theresistance member 4 so as to adjust the friction coefficient between theresistance member 4 and the secondlower arc cavity 23, thereby regulating the magnitude of the resistance (as shown inFIG. 4 ). - With reference to
FIG. 5 , an embodiment of the invention uses the combination of components such as the regulatingrotary lid 3, thedisc body 1, thesemispherical base 2 and theresistance member 4, and the magnitude of the friction force (i.e., the normal force) between theresistance member 4 and the secondlower arc cavity 23 of thesemispherical base 2 that is controlled by thescrew rod 32 driven by the regulatingrotary lid 3 to achieve the purpose of regulating torque so as to change and balance the magnitude of the movement resistance. Therefore, with the forces imposed by left and right legs, a user can stand on thedisc body 1 of the balance board to make thedisc body 1 capable of being tilted around 360 degrees or retained at the horizontal position so as to perform balance exercise training and fitness. The maximum angle of tilting thedisc body 1 is a half of the inverted cone angle θ of thepivot hole 24. Normally, the inverted cone angle θ is preferably at 40 to 45 degrees. - While using an embodiment of the invention, the lodging portion 421 (as shown in
FIG. 6 ) of thehollow tube body 42 of theresistance member 4 is lodged into the cross-shaped throughhole 13 of thedisc body 1, and theresistance member 4 and theelastic component 5 are locked and connected as a whole by using the lockingmember 6 and thescrew rod 32. Therefore, thedisc body 1 and theresistance member 4 are co-linked when the user tilts. Only thesemispherical base 2 is retained on the ground without movement. Further, the regulatingrotary lid 3 includes a plurality of circularlydisposed holes 33 to facilitate extension of the fingers of the user for rotation purposes. Accordingly, thescrew rod 32 can be driven 3 to vertically and spirally move by rotating the regulatingrotary lid 3, thereby regulating the magnitude of the torque between theresistance member 4 and the secondlower arc cavity 23. - While the means of specific embodiments in the present invention have been described with reference to the drawings, numerous other modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the invention set forth in the claims. The modifications and variations should in no way be limited by the specification of the present invention.
