DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-5, an exercising device 1 in accordance with the preferred embodiment of the present invention comprises a support frame 11, a pivot unit 12, a footrest 13, a backrest bar 14, and two armrests 15.
The support frame 11 is substantially inverted V-shaped, and includes a front stand 111, a rear stand 112 pivotally connected with the front stand 111, and a pivot shaft 113 pivotally mounted between the front stand 111 and the rear stand 112. The front stand 111 of the support frame 11 is substantially U-shaped, and has an upper end provided with a tube 114 having a mediate portion formed with an opening 115. The rear stand 112 of the support frame 11 is substantially U-shaped, and has an upper end provided with two opposite mounting tubes 116 each mounted on the tube 114 of the front stand 111 and provided with a crossbar 117 located below the two mounting tubes 116. The crossbar 117 has a mediate portion provided with a stop block 119. The rear stand 112 of the support frame 11 is provided with two opposite mounting sleeves 118. The pivot shaft 113 of the support frame 11 is extended through the two mounting tubes 116 of the rear stand 112 and the tube 114 of the front stand 111.
The pivot unit 12 is pivotally mounted on the support frame 11, and includes an operation lever 121 pivotally mounted on the pivot shaft 113 of the support frame 11, and a threaded swivel shaft 124 rotatably mounted on the operation lever 121. The operation lever 121 of the pivot unit 12 is located in the opening 115 of the tube 114 of the front stand 111 and is formed with a transverse hole 121 b for passage of the pivot shaft 113 of the support frame 11. The operation lever 121 of the pivot unit 12 has a mediate portion formed with a shaft hole 121 a for passage of the swivel shaft 124.
The footrest 13 is mounted on the pivot unit 12 and includes a fixed section 131 having a first end secured on an upper end of the swivel shaft 124 of the pivot unit 12 to rotate therewith, and a movable section 132 having a first end movably mounted in the fixed section 131 and a second end protruded outward from a second end of the fixed section 131. The footrest 13 further includes a seat plate 134 secured on the first end of the fixed section 131. The footrest 13 further includes an arc-shaped connecting seat 138 secured on the second end of the movable section 132, and a footrest seat 133 secured on the connecting seat 138 by a plurality of screw members 139. The second end of the fixed section 131 of the footrest 13 has a top formed with a positioning hole 135, the movable section 132 of the footrest 13 has a top formed with a plurality of threaded adjusting holes 137, and the footrest 13 further includes a threaded adjusting member 136 extended through the positioning hole 135 of the fixed section 131 and screwed into a respective one of the adjusting holes 137 of the movable section 132.
The pivot unit 12 further includes an upper bearing 122 mounted on the swivel shaft 124 and located between the fixed section 131 of the footrest 13 and the operation lever 121 of the pivot unit 12, a nut 125 screwed on a lower end of the swivel shaft 124, and a lower bearing 123 mounted on the swivel shaft 124 and located between the operation lever 121 of the pivot unit 12 and the nut 125.
Each of the upper bearing 122 and the lower bearing 123 includes a mounting ring d, a fixing race f secured on the mounting ring d, and a ball ring e mounted between the mounting ring d and the fixing race f.
The operation lever 121 of the pivot unit 12 has a first end formed with a through hole 121 c, the first end of the fixed section 131 has a bottom formed with a threaded locking hole 1310, and the pivot unit 12 further includes a threaded fixing member 126 extended through the through hole 121 c of the operation lever 121 and screwed into the locking hole 1310 of the fixed section 131, so that the fixed section 131 of the footrest 13 is fixed on the operation lever 121 of the pivot unit 12. The operation lever 121 of the pivot unit 12 has a second end that can be pivoted to abut the stop block 119 of the support frame 11.
The backrest bar 14 is substantially L-shaped, and has a horizontal section secured on the fixed section 131 of the footrest 13 by a fixing member 142 and a vertical section provided with a backrest 141.
Each of the two armrests 15 is mounted on the rear stand 112 of the support frame 11 and has a lower end inserted into a respective one of the two mounting sleeves 118.
In operation, referring to FIGS. 6 and 7 with reference to FIGS. 1-5, the fixing member 126 of the pivot unit 12 is unscrewed from the locking hole 1310 of the fixed section 131, so that the fixed section 131 of the footrest 13 is released from the operation lever 121 of the pivot unit 12. Then, the swivel shaft 124 can be rotated on the operation lever 121 of the pivot unit 12, so that the fixed section 131 and the seat plate 134 of the footrest 13 can be swiveled on the operation lever 121 of the pivot unit 12 the swivel shaft 124, thereby achieving the effect of exercising the user's feet and waist.
Referring to FIG. 8 with reference to FIGS. 1-5, the fixing member 126 of the pivot unit 12 is screwed into the locking hole 1310 of the fixed section 131, so that the fixed section 131 of the footrest 13 is fixed on and combined with the operation lever 121 of the pivot unit 12. Thus, the fixed section 131 and the seat plate 134 of the footrest 13 and the operation lever 121 of the pivot unit 12 can be pivoted about the pivot shaft 113 of the support frame 11, thereby achieving the effect of exercising the user's feet, back and waist.
Referring to FIG. 9 with reference to FIGS. 1-5, the backrest bar 14 is removed from the fixed section 131 of the footrest 13. Then, the fixed section 131 and the seat plate 134 of the footrest 13 and the operation lever 121 of the pivot unit 12 can be pivoted about the pivot shaft 113 of the support frame 11 until the second end of the operation lever 121 of the pivot unit 12 is rested on the stop block 119 of the support frame 11, so that the footrest seat 133 of the footrest 13 is located higher than the pivot shaft 113 of the support frame 11, thereby facilitating the user practicing the skill of upside down.
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.
