Detailed Description of the Preferred Embodiments

Please refer to the FIGS. 1 through 7 , which are the exploded and combinational illustrative views showing the structures of the hip training apparatus for the present invention.
The hip training apparatus comprises a chassis 1 and a pair of pivotable treadles 2, wherein, said chassis 1 includes a deck cover 10 and a soleplate 10'. At the both front sides of the deck cover 10, two symmetrical perforated holes 11 are configured for holding each of two pivotable treadles 2 therein; at the breech portion of the deck cover 10, a ramp 14 is symmetrically formed at each left and right side descending from the central line outwards laterally such that one curved trough 12 with curved track 121 therein is configured at each ramp 14.
For the purpose of enabling the user to carry the hip training apparatus on if necessary, at the front rim of the chassis 1, a carrying handle 13 is built on the deck cover 10 such that an aperture 131 with two lateral symmetrical slits 132 are configured thereon for having an elastic strap 4 passed inside the aperture 131 with two ends staying outside of the slits 132 for user to grasp; at the rear rim of the deck cover 10 for the chassis 1, an adjusting wing nut 15 is built on the deck cover 10.
Said pair of pivotable treadles 2, which are symmetrically pivot juxtaposed on the chassis 1, have plural nipple studs 21 formed on the top surface so as to correspond to the plantar reflective acupuncture points for both of physiological massaging to the plantar tissue and supporting the anti-slipping friction during inwards pressing exercise by two feet of the user. At the front end and rear end of each back side of the pair of pivotable treadles 2 are a pivot axle 22 and a roller 23 respectively, which is securely fixed on the bottom thereof by a fitting frame 231 and a spring cushion 232. At the heel holding position of the rear end around each said pivotable treadle 2, an arched heel aligning ledge 25 is erected for enabling the user to perform inwards pressing exercise by two feet. Because the size of human sole is different from person to person, only heel holding position instead of toe holding position, the heel aligning ledge 25 is formed thereon to avoiding the confinement of the toe holding position, which is different from person to person due to different sole size.
During assembly, each pivot axle 22 of the pivotable treadle 2 is firstly set in each corresponding perforated holes 11 for deck cover 10 of the chassis 1 so that each roller 23, which is disposed on the pivotable treadle 2 with a spring cushion 232, is just lodged in each corresponding curved trough 12 of the deck cover 10; Then, each locking bore 242, which is to set on the joint lever slat 24 at the sole of the deck cover 10, is securely fitted and locked on each corresponding pivot peg 221 on the pivot axle 22 at the bottom of the pivotable treadle 2 by each locking screw 241 so that each pivotable treadle 2 can do pivotal movement in ascending inwards back and forth manner with each pivot axle 22 as center in each corresponding prefabricated curved track 121 of the curved trough 12 on the deck cover 10.
Please refer to the FIGS. 5 and 6 , the both ends of the elastic belt 17 is secured on the joint lever slats 24. By suitably turning the adjusting wing nut 15, which drives the nut 152 via threaded rod 151 interconnecting the front bored angle piece 181 of the J-shape hook slat 18 in and out via associated threaded rod 151, the rear hook end 182 of the J-shape hook slat 18 will accordingly pull and release the middle section of the elastic belt 17 transversely for turning the joint lever slats 24 connected so that torsional tension exerting on two pivotable treadles 2 is altered in gradient manner accordingly; wherein, the nut 152 on the threaded rod 151 is used as tension adjuster and a holding plate 153 is disposed beneath the threaded rod 151 for preventing it from bounce due to exceeding pulling force.
Please refer to FIGS. 8 and 9 , which are the operational views for the hip training apparatus of the present invention. During operation, each foot of the exerciser stands on each corresponding pivotable treadle 2 of the chassis 1 with heel abut with the heel aligning ledge 25 over the roller 23 and performs inwards pressing exercise by two feet simultaneously so that each pivotable treadle 2 follows the foot movement doing pivotal movement in ascending inwards back and forth manner in the curved trough 12 on the deck cover 10 with each pivot axle 22 as center. During non-operation status, both rear ends of the pivotable treadles 2 are borne the torque to laterally outmost position because the pivot axle 22 at the bottom front end of the pivotable treadle 2 is pulled by the elastic belt 17. Therefore, the greater is the tension of the elastic belt 17, the more exerting effort is required by the exerciser to draw the two pivotable treadles 2 together so as to enhance the hip training. Moreover, to only turn the adjusting wing nut 15 on the chassis 1 in proper degree, the torsional tension of the pivotable treadles 2 can be suitably adjusted in gradient manner via pulling force of the J-shape hook slat 18, which being driven by the connected nut 152 with threaded rod 151, acting on the elastic belt 17 with two pivotable joint lever slats 24. When the elastic belt 17 is pulled tightly, each end of both joint lever slats 24 is pulled towards the adjusting wing nut 15 so that the pivot peg 221 on the pivot axle 22 at the bottom of the pivotable treadle 2 is borne the torque from the connected locking bore 242 of the joint lever slat 24. Thereby, both rear ends of the pivotable treadles 2 follow the torque being tensely twisted towards laterally; contrarily, when the elastic belt 17 is released loosely, the pivotable treadles 2 become more movable due to less of the torsional tension borne on the joint lever slats 24. Thus, the user can achieve the gradient adjustment in such way.
Please further refer to the FIGS. 10 and 11 , which show the structures of the aperture 131 and slit 132 on the handle 13. The stretchable elastic strap 4 is put in two apertures 131 via the associated slit 132 thereof. Because of the slant-cut shape in the slit 132, the elastic strap 4 is difficult to get off once it has been put in the carrying handle 13 so that the user can arbitrarily perform stretch and twist physical exercise with entire body in balance manner at will.
