exercising device, wherein the user has to exert a force to
overcome the elastic force of the belts, thereby achieving the
purpose of exercising the user's body.
[0008] A further objective of the present invention is to provide
an exercising device, wherein the rocking bar is arc-shaped so as
to satisfy the ergonomic design, so that the user can operate the
exercising device in a comfortable and safe manner.
[0009] A further objective of the present invention is to provide
an exercising device, wherein the user can operate the exercising
device easily and conveniently, thereby facilitating the user
operating the exercising device.
[0010] In accordance with the present invention, there is provided
an exercising device comprising:
[0011] a main frame;
[0012] a support frame pivotally mounted on the main frame; and
[0013] an arc-shaped rocking bar fixed on the main frame.
[0014] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0023] Referring to the drawings and initially to FIGS. 2 and 3, an
exercising device in accordance with the preferred embodiment of
the present invention comprises a main frame 10, a retractable bar
20, two operation handles 25, a support frame 30, and an arc-shaped
rocking bar 60.
[0024] The main frame 10 has a first end formed with a plurality of
adjusting holes 14 and a second end provided with a transverse
support bar 11. The main frame 10 has a mediate portion provided
with a fixed tube 13. The main frame 10 is provided with two fixing
plates 12 for mounting a backrest 40 by a plurality of screw
members 90.
[0025] The retractable bar 20 is retractably mounted on the first
end of the main frame 10 and has a first end formed with a
positioning hole 24 aligning with one of the adjusting holes 14 of
the main frame 10 and a second end provided with a transverse
fixing bar 21 for mounting a head cushion 50 by a plurality of
screw members 900.
[0026] The exercising device further comprises a substantially
V-shaped elastic plate 22 mounted in the retractable bar 20 and
having a distal end provided with a positioning stub 220 extended
through the positioning hole 24 of the retractable bar 20 and
detachably locked in one of the adjusting holes 14 of the main
frame 10.
[0027] Each of the two operation handles 25 is adjustably mounted
on the support bar 11 of the main frame 10. Each of the two
operation handles 25 has a first end provided with a protective
grip 26 and a substantially arc-shaped second end. Each of the two
operation handles 25 has a mediate portion provided with a
transverse adjusting bar 27 adjustably mounted in the support bar
11 of the main frame 10.
[0028] The support frame 30 is substantially inverted Y-shaped and
is pivotally mounted on the main frame 10. The support frame 30 has
a first end formed with a substantially U-shaped pivot rack 32
pivotally mounted on the fixed tube 13 of the main frame 10 by a
bolt 34 and a nut 36 and a second end formed with two support legs
38 each pivotally provided with a roller 31 by a bolt 902 and a nut
904. The pivot rack 32 of the support frame 30 is provided with a
protruding limit rod 80.
[0029] The rocking bar 60 has two ends each fixed on the main frame
10 by a screw member 906. The rocking bar 60 is provided with a
protruding limit rod 802.
[0030] The exercising device further comprises two opposite belts
70 each having a first end secured on an end of the limit rod 802
of the rocking bar 60 and a second end secured on an end of the
limit rod 80 of the pivot rack 32 of the support frame 30.
[0031] As shown in FIGS. 2-4, the positioning stub 220 of the
elastic plate 22 mounted in the retractable bar 20 is extended
through the positioning hole 24 of the retractable bar 20 and
detachably locked in one of the adjusting holes 14 of the main
frame 10, so that the retractable bar 20 is retractably mounted on
the first end of the main frame 10 to adjust the height of the head
cushion 50 so as to fit users of different heights.
[0032] In operation, referring to FIGS. 2-8, the user's two hands
hold the protective grips 26 of the two operation handles 25, with
his/her back being rested on the backrest 40, and with his/her head
being rested on the head cushion 50 as shown in FIG. 7. Then, the
user's body is moved backward to press the main frame 10 backward
as shown in FIG. 8 so as to rock the rocking bar 60 and to pivot
the support frame 30, so that the support frame 30 is pivoted from
the position as shown in FIG. 5 to the position as shown in FIG. 6
to extending the belts 70. Thus, the user has to exert a force to
overcome the elastic force of the belts 70, thereby achieving the
purpose of exercising the user's waist.
[0033] Accordingly, the user has to exert a force to overcome the
elastic force of the belts 70, thereby achieving the purpose of
exercising the user's body. In addition, the rocking bar 60 is
arc-shaped to satisfy the ergonomic design, so that the user can
operate the exercising device in a comfortable and safe manner.
Further, the user can operate the exercising device easily and
conveniently, thereby facilitating the user operating the
exercising device.
[0034] 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.
