the seat is only swiveled relative to the support frame and cannot
be pivoted leftward and rightward relative to the support frame,
thereby limiting the exercising or rehabilitating function of the
rehabilitation exercising equipment. In addition, the seat is
driven manually by the user and cannot be moved automatically so
that the user cannot move the seat easily when his/her body is
injured, thereby greatly limiting the rehabilitating function of
the rehabilitation exercising equipment. Further, the
rehabilitation exercising equipment has a complicated construction
and is not assembled easily and quickly, thereby increasing the
cost of fabrication and assembly.

[0024] The pivot mechanism 12 is pivotable leftward and rightward
relative to the main frame 1 and is swivelable horizontally
relative to the main frame 1. The pivot mechanism 12 includes a
rotation shaft 18 rotatably mounted on the main frame 1, and two
first bearings 131 each pivotally mounted on the rotation shaft 18
and each connected with the seat unit 20 so that the seat unit 20
is movable in concert with the two first bearings 131 relative to
the rotation shaft 18. The pivot mechanism 12 further includes two
second bearings 13 each mounted between the main frame 1 and the
rotation shaft 18, a support shaft 19 mounted on the rotation shaft
18 and extended through each of the two first bearings 131 to
support the two first bearings 131, a fixing plate 141 mounted on
an upper end of the rotation shaft 18, and two buffering pads 15
each mounted on the fixing plate 141 and each located between the
fixing plate 141 and the seat unit 20.
[0025] The rotation shaft 18 of the pivot mechanism 12 is disposed
at an upright state. The rotation shaft 18 of the pivot mechanism
12 is extended through the two second bearings 13 and the mounting
hole 111 of the mounting bracket 11. The rotation shaft 18 of the
pivot mechanism 12 is rotatably mounted on the mounting bracket 11
of the main frame 1 and is rotatably mounted in the two second
bearings 13. The rotation shaft 18 of the pivot mechanism 12 is
rotatable relative to the main frame 1 in a first (vertical)
direction, and each of the two first bearings 131 of the pivot
mechanism 12 is rotatable relative to the main frame 1 in a second
(horizontal) direction that is perpendicular to the first
(vertical) direction of the rotation shaft 18. The support shaft 19
of the pivot mechanism 12 is perpendicular to the rotation shaft

[0026] The two first bearings 131 of the pivot mechanism 12 are
disposed between the rotation shaft 18 and the seat unit 20. Each
of the two first bearings 131 of the pivot mechanism 12 is
pivotally mounted on the support shaft 19. Each of the two first
bearings 131 of the pivot mechanism 12 has a top provided with a
locking plate 14 locked onto a bottom of the seat unit 20. Each of
the two first bearings 131 of the pivot mechanism 12 is
perpendicular to each of the two second bearings 13. Each of the
two second bearings 13 of the pivot mechanism 12 is affixed to the
mounting bracket 11 of the main frame 1 by the locking holes 112 of
the mounting bracket 11, and the top plate 110 of the mounting
bracket 11 is sandwiched between the two second bearings 13 of the
pivot mechanism 12.
[0027] In operation, referring to FIGS. 5-7 with reference to FIGS.
1-4, each of the two first bearings 131 of the pivot mechanism 12
is rotated relative to the main frame 1 in the horizontal direction
so that the seat unit 20 is pivoted leftward and rightward relative
to the main frame 1 as shown in FIGS. 5 and 6. In such a manner,
when a user is seated on the seat unit 20 as shown in FIG. 7,
he/she can apply a force on the seat unit 20 to pivot the seat unit
20 leftward and rightward relative to the main frame 1 so as to
achieve an exercising, balance or rehabilitating function.
[0028] Alternatively, referring to FIGS. 8-10 with reference to
FIGS. 1-4, the rotation shaft 18 of the pivot mechanism 12 is
rotated relative to the main frame 1 in the vertical direction so
that the seat unit 20 is swiveled horizontally relative to the main
frame 1 as shown in FIGS. 8 and 9. In such a manner, when a user is
kneeled or seated on the seat unit 20 as shown in FIG. 10, he/she
can apply a force on the seat unit 20 to swivel the seat unit 20
horizontally relative to the main frame 1 so as to achieve an
exercising or rehabilitating function.
[0029] Referring to FIGS. 11-13, the rehabilitation exercising
equipment further comprises a transmission mechanism 3 mounted
between the main frame 1 and the pivot mechanism 12. The
transmission mechanism 3 includes a drive geared member 31 mounted
on the rotation shaft 18 of the pivot mechanism 12 to move in
concert with the rotation shaft 18 of the pivot mechanism 12, a
drive unit 30 mounted on the main frame 1, a driving geared member
32 rotatably mounted on the drive unit 30, and a linking member 33
mounted between the driving geared member 32 and the drive geared
member 31 to link the driving geared member 32 and the drive geared
member 31.
[0030] The drive geared member 31 of the transmission mechanism 3
is secured on a lower end of the rotation shaft 18 of the pivot
mechanism 12 and is located under the two second bearings 13 of the
pivot mechanism 12. The drive geared member 31 of the transmission
mechanism 3 is rotatably mounted on the drive unit 30. The drive
unit 30 of the transmission mechanism 3 is received in the mounting
bracket 11 of the main frame 1 and is located under the pivot
mechanism 12. The drive unit 30 of the transmission mechanism 3 is
electrically connected to and controlled by the control panel 17 of
the main frame 1.
[0031] In the preferred embodiment of the present invention, the
drive unit 30 of the transmission mechanism 3 is a magnetically
controlled resistance device. Alternatively, the drive unit 30 of
the transmission mechanism 3 is a powered motor. In addition, the
linking member 33 is a toothed belt. Alternatively, each of the
driving geared member 32 and the drive geared member 31 is a
sprocket, while the linking member 33 is a chain.
[0032] In operation, when the drive unit 30 of the transmission
mechanism 3 is a magnetically controlled resistance device, the
drive unit 30 provides a damping force to the driving geared member
32 and the drive geared member 31 by connection of the linking
member 33 to damp rotation of the rotation shaft 18 of the pivot
mechanism 12 so as to provide a resistance to the seat unit 20 so
that the user has to apply a larger force to swivel the seat unit
20 horizontally relative to the main frame 1, thereby enhancing the
exercising or rehabilitating effect. At this time, the damping
force of the drive unit 30 is controlled by the control panel 17 of
the main frame 1.
[0033] Alternatively, when the drive unit 30 of the transmission
mechanism 3 is a powered motor, the drive unit 30 drives the
driving geared member 32 which drives the linking member 33 which
drives the drive geared member 31 which drives the rotation shaft
18 which drives the seat unit 20 so that the seat unit 20 is driven
by the drive unit 30 and is swiveled horizontally relative to the
main frame 1 so as to achieve a rehabilitating function
automatically.
[0034] Accordingly, the seat unit 20 is pivoted leftward and
rightward relative to the main frame 1 and is swiveled horizontally
relative to the main frame 1 so as to achieve an exercising,
balance or rehabilitating function. In addition, the drive unit 30
of the transmission mechanism 3 functions as a magnetically
controlled resistance device to provide a damping force to the seat
unit 20 so that the user has to apply a larger force to swivel the
seat unit 20 horizontally relative to the main frame 1, thereby
enhancing the exercising or rehabilitating effect. Further, the
drive unit 30 of the transmission mechanism 3 functions as a
powered motor to drive the seat unit 20 so that the seat unit 20 is
driven by the drive unit 30 and is swiveled horizontally relative
to the main frame 1 so as to achieve a rehabilitating function
automatically. Further, the rehabilitation exercising equipment has
a simplified construction and is assembled easily and quickly to
decrease the cost of fabrication and assembly.
[0035] 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.
