Please refer to the first to seventh figures, the creation of the "resistance adjustment balance board", the composition comprising a disk 1, a ball seat 2, an adjustment cap 3, a resistance member 4, an elastic member 5 and a lock 6; Wherein: the disk body 1 is provided with an upper groove 11 on the top surface thereof for adjusting the screw cap 3, the bottom surface of the disk body 1 is provided with a first lower arc groove 12 for being placed in the hemispherical seat 2, and a through hole 13 is defined between the upper groove 11 and the first lower arc groove 12, and the through hole is 13 is formed in a cross shape, and the locking portion 421 of the hollow tubular body 42 of the resistance member 4 is engaged with the through hole 13. Further, the upper surface of the disk body 1 is provided with a plurality of bumps 14 and grooves 15, which have a slip preventing effect with respect to the user's foot, and the lower surface of the disk body 1 is provided with a plurality of ribs 16, The disc 1 of the same structural strength is further obtained using less material.

The hemispherical seat 2 has a top arc surface 211 of the upper edge and a first lower arc groove 12 of the disc body 1 which can be fitted and fitted. The bottom end is provided with a bottom plate 22, and the outer diameter of the bottom plate 22 is set to be larger than the hemisphere seat. The outer diameter of 2 provides the overall stability and support of the balance plate of the present invention. Further, the abdomen of the hemispherical seat 2 is provided with a second lower arc groove 23 for inserting the resistance member 4, and a perforation 24 of a larger movable space is arranged above the second lower arc groove 23, and the perforation 24 is provided. It is inverted cone. The angled ring 211 of the hemispherical seat 2 is provided with a plurality of grooves 222 at equal angles, and lubricating oil can be disposed in the grooves 222 to provide the first arc of the disk body 1 when the balance plate is used by the user. The lubricating effect of the groove 12 and the top arc surface 211 of the hemispherical seat 2 enhances the service life of the balance plate of the present invention.

The adjusting cap 3 is provided with a hexagonal locking hole 311 in the center of the inner edge of the cover 31, and the hexagonal head of one screw 32 can be placed inside to achieve the purpose of bonding. Of course, the screw 32 can also be integrally formed in the in-mold, and is integrally fixed to the locking hole 311 of the adjusting cap 3, so that the cover 31 and the screw 32 have a linkage relationship.

The resistance member 4 has a hollow tube body 42 extending from the top surface of the half ball portion 41. The top end of the hollow tube body 42 is provided with a locking portion 421, and the locking portion 421 is engaged with the cross of the disc body 1. The through hole 13 is formed in a shape such that the curved surface 43 of the hemispherical portion 41 and the second lower arc groove 23 of the hemispherical seat 2 have a fitting structure. Further, the abdomen position of the resistance member 4 is provided with a chamber 44. The chamber 44 is composed of a first chamber 441 and a second chamber 442. The first chamber 441 is disposed in the hollow tube body 42. The second chamber 442 is connected to the lower portion of the first chamber 441 and has a hexagonal structure. The hexagonal lock 6 is fixed and cannot be rotated when the hexagonal lock 6 is disposed, so that the lock 6 is The screw 32 cooperates to lock the disk body 1, the hemispherical seat 2 and the resistance member 4. That is, one end of the screw 32 is fixed by the through hole 13 of the disc body 1 in the first chamber 441 and the lock member 6 is locked.

It is further explained that when the screw 32 and the locking member 6 are locked, the resistance member 4 can exert strong friction resistance by being pressed tightly with the second lower arc groove 23 of the hemispherical seat 2 to exhibit strong resistance. There are two ways of generating resistance. One is to make the resistance member 4 made of a soft elastic material. When the screw 32 is fitted with the locking member to fix the resistance member 4 in the hemispherical seat 2, the adjustment screw cap 3 can be rotated. The degree of tightness of the screw 32 is fixed, and the friction coefficient between the resistance member 4 and the second lower arc groove 23 is controlled to adjust the magnitude of the resistance (as shown in Fig. 7).

In the second mode, the elastic member 5 is disposed in the second chamber 442, and the elastic member 5 is sheathed by the screw 32. When the screw 32 and the locking member 6 are screwed, the adjusting cap 3 can be adjusted by the screw cap 3. Rotating the screw 32 causes the elastic member 5 to press the resistance member 4 to control the friction coefficient between the resistance member 4 and the second lower arc groove 23 to achieve the adjustment resistance (as shown in Fig. 4).

Referring to FIG. 5, the present invention controls the resistance member 4 and the hemispherical seat 2 by adjusting the combination of the screw cap 3, the disk body 1, the hemispherical seat 2, and the resistance member 4, etc., by using the adjusting screw cap 3 to drive the screw 32. The friction between the two lower arc slots 23 (that is, the so-called positive force in mechanics) achieves the purpose of adjusting the torsion force, thereby changing the magnitude of the balance motion resistance. Therefore, the user can stand on the disk body 1 of the balance board, and through the force of the left and right feet, the disk body 1 can be tilted 360 degrees or the disk body 1 can be maintained horizontally for balance exercise training and fitness. The maximum angle at which the disk body 1 can be tilted is half of the reverse taper angle θ of the through hole 24. Usually, the reverse taper angle θ is preferably between 40 degrees and 45 degrees.

In the present invention, the hollow tube body 42 of the resistance member 4 has a locking portion 421 (shown in FIG. 6) engaged with the cross-shaped through hole 13 of the disk body 1, plus a resistance member 4, and elasticity. The element 5 is integrally coupled to the screw 32 by the lock member 6. Therefore, the disk body 1 and the resistance member 4 are interlocked together under the condition that the user is inclined, and only the hemispherical seat 2 is maintained on the ground. Moreover, the adjusting screw cap 3 ring is provided with a plurality of holes 33, In order to facilitate the user's finger to extend and rotate, the screw 32 can be driven to rotate up and down by rotating the adjusting cap 3 to achieve the torque between the adjusting resistance member 4 and the second lower arc groove 23.

In summary, the present invention has excellent advancement and practicability in similar products, and at the same time, the technical materials of such structures are not frequently found in the literature and the literature, and the same structure is not found in the literature. The invention already has the invention patent requirements, and the application is filed according to law.

The embodiments described above are intended to be illustrative only, and various modifications, adaptations and applications may be made by those skilled in the art without departing from the scope of the invention.
