Therefore, rotating shaft of pedal or decelerating motor can simultaneously or respectively drive driven gear sector to rotate eccentric shaft, then apply first clutch assembly to control driven gear sector to drop off gear sector of main shaft, so that chair can turn round automatically with eccentric shaft as axis. Also apply second clutch assembly to control transmission gear of decelerating motor to drop off main gear of main shaft, thus, rotating shaft of pedal can move driven gear sector, so, user can turn around hip and waist at the same time while rotating shaft of pedal.
4. As claimed in claim 1 , 2 , 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein axial runner is made in lower part of screw thread of eccentric shaft, and axial track matching axial runner is made in Peg-in-Hole of driven gear sector, so that this axial track can be embedded into this axial runner, driven gear sector can move upward/downward within this axial runner.
5. As claimed in claim 1 , 2 , 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein one relay sleeve can be fixed on top of this sleeve, which is also connected with relay shaft, eccentric shaft can be embedded into this relay sleeve for flexing, then lock this relay sleeve with lock bolt so that it leans against this eccentric shaft, eccentric chair is thereby adjusted according to height of user.
6. As claimed in claim 1 , 2 , 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein chair is pivoted with eccentric shaft, adjust seat is fixed at top of eccentric shaft, and shaft lever is assembled at bottom of chair, with support of shaft collars connecting to front of adjust lever, this shaft lever embedded into this shaft collars can let chair rotate freely, furthermore, this adjust lever can be embedded into from two ends of adjust seat, which can adjust distance between chair and eccentric shaft, then pass fixing bolt through adjust seat to position adjust lever, so that eccentric shaft can be adjusted properly as required when driven.
7. As claimed in claim 1 , 2 , 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein features of the structure to connect driven gear sector and relay shaft as follows:
Axial track (runner) is made in hole of this driven gear sector;
This relay shaft, axial runner (track) is fixed matching this axial track (runner).
Therefore, axial runner (track) of this relay shaft is embedded into axial track (runner) of driven gear sector's hole, so that driven gear sector can move upward/downward in axial runner (track) of this relay shaft, which can drive eccentric shaft to rotate.
8. As claimed in claim 2 , 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein the decelerating motor is fixed at pivot seat, and this pivot seat is pivoted to this bracket with pivot shaft, moreover, fixing seat also is fixed at this pivot seat, which can fix 2nd clutch assembly, so that pivot seat can drive decelerating motor to sway forward/backward.
9. As claimed in claim 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein spring can cover onto axial runner of relay, so that the compressed spring is positioned between nut and driven gear sector, which will be compressed and reset by driven gear sector.
10. As claimed in claim 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein the first clutch assembly is comprised by following components:
Splint which is inserted into ring groove set between compressed spring and driven gear sector;
Fixing lever is fixed at terminal of this splint;
Spring is covered onto this fixing lever and fixed on the board, so that this spring is positioned between splint and board.
Adjuster, its guide rope fastens this board, and rope collars coating this guide rope is limited within this splint with one bolt and positioned between fixing lever and relay shaft of driven gear sector;
Thus, this adjuster can adjust its guide rope and control splint to push upward compressed spring or release driven gear sector, so that this driven gear sector can move up/down in axial runner of relay shaft with above said axial track, so, driven gear sector can drop off or mesh with gear sector, therefore, user can select power source at will.
11. As claimed in claim 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein the second clutch assembly is comprised by following components:
Pivot seat where one fixing seat is fixed properly.
Limit lever which passes through this fixing seat and fixes on hook;
Spring which covers onto limit lever;
Adjuster is to fasten the guide rope to this hook, and rope collar of this guide rope is positioned at this fixing seat with one bolt;
Thus, adjuster is to adjust guide rope and bolt is to strain or loose the guide rope so as to control this pivot seat to sway with pivot shaft as axis, transmission gear thereby drop off or mesh with main gear.
12. As claimed in claim 1 , it is chair-rotating control mechanism applied to sport apparatus, wherein this mechanism is applicable to bicycle and exercising bicycle.
13. As claimed in claim 2 , 3 , it is chair-rotating control mechanism applied to sport apparatus, wherein this mechanism is applicable to exercising bicycle.
14. As claimed in claim 2 , it is chair-rotating control mechanism applied to sport apparatus, wherein this mechanism can also be applicable to AB chair if not equipped with auxiliary sprocket and rotating shaft of pedal.
