[0029] Each of the elastic bars 24 has two ends each provided with
a pulley 26 formed with two slideways 28. Each of the two ends of
each of the elastic bars 24 has a side formed with two snap holes
20 each aligning with a respective one of the two slideways 28 of
the respective pulley 26.
[0030] Each of the pulling devices 40 is mounted on a respective
one of the elastic bars 24 and includes a pulling belt 41 having
two ends, and two pulling ropes 45 each having a first end secured
on a respective end of the respective elastic bar 24 and a second
end secured on the elastic pulling belt 41.
[0031] Preferably, the pulling belt 41 has a periphery provided
with a holding member 43 to facilitating the user's one hand
holding the pulling belt 41. Each of the two ends of the pulling
belt 41 is provided with a snap hook 44.
[0032] The first end of each of the pulling ropes 45 is extended
through a respective one of the two slideways 28 of the pulley 26
of the respective elastic bar 24 and is provided with a snap hook
46 snapped into a respective one of the two snap holes 20 of the
respective elastic bar 24. Thus, the slideway 28 of the pulley 26
can be used to guide and position each of the pulling ropes 45,
thereby preventing from detachment of each of the pulling ropes 45.
The second end of each of the pulling ropes 45 is provided with a
snap hook 47 snapped on the respective snap hook 44 of the pulling
belt 41.
[0033] Each of the pulling devices 40 further includes two
auxiliary pulling ropes 450 each having a first end secured on a
respective end of the respective elastic bar 24 and a second end

the two slideways 28 of the pulley 26 of the respective elastic bar
24 and is provided with a snap hook 460 snapped into a respective
one of the two snap holes 20 of the respective elastic bar 24.
Thus, the slideway 28 of the pulley 26 can be used to guide and
position each of the auxiliary ropes 450, thereby preventing from
detachment of each of the auxiliary pulling ropes 450. The second
end of each of the auxiliary pulling ropes 450 is provided with a
snap hook 470 snapped into the snap hole 19 of a respective end of
the respective holding face 14 of the holding body 12.
[0034] In operation, referring to FIGS. 4 and 5, the user's two
hands can hold the holding member 43 of the pulling belt 41 of each
of the pulling devices 40 to pull the pulling ropes 45 of each of
the pulling devices 40 to expand outward relative to the holding
body 12, so as to pull and bend the elastic bars 24, thereby
achieving the purpose of exercising the user's two hands, chest
muscle and abdominal muscle.
[0035] At this time, each of the two pulling ropes 45 has a first
end secured on a respective end of the respective elastic bar 24
and a second end secured on the elastic pulling belt 41, while each
of the auxiliary pulling ropes 450 has a first end secured on a
respective end of the respective elastic bar 24 and a 20 second end
secured on the holding body 12, so that each of the auxiliary
pulling ropes 450 exerts a force opposite to the pulling force
exerted by each of the two pulling ropes 45, so that the user's two
hands have to exert a larger force to overcome the force applied by
each of the auxiliary pulling ropes 450, so as to pull and bend the
elastic bars 24, thereby enhancing the exercising effect.
[0036] Referring to FIGS. 6 and 7, the body exercising device 10 is
placed on the user's back. Thus, the user's two hands can hold the
holding member 43 of the pulling belt 41 of each of the pulling
devices 40 to pull the pulling ropes 45 of each of the pulling
devices 40 to expand outward relative to the holding body 12, so as
to pull and bend the elastic bars 24, thereby achieving the purpose
of exercising the user's two hands and back muscle.
[0037] Referring to FIG. 8, the body exercising device 10 is
available for the user having shorter arms. In practice, the user's
one hand can hold the holding body 12 and the user's other hand can
hold the holding member 43 of the pulling belt 41 of one of the
pulling devices 40 to pull the pulling ropes 45 of the respective
pulling device 40 to expand outward relative to the holding body
12, so as to pull and bend the respective elastic bar 24, thereby
achieving the purpose of exercising the user's two hands. Thus, the
body exercising device 10 is available for users of different
stature.
[0038] Referring to FIGS. 9-11, in accordance with another
embodiment of the present invention, each of the two auxiliary
pulling ropes 450 of each of the pulling devices 40 has a first end
secured on a respective end of the respective elastic bar 24 and a
second end secured on the elastic pulling belt 41. The first end of
each of the auxiliary pulling ropes 450 is provided with a snap
hook 460 extended through a respective one of the two slideways 28
of the pulley 26 of the respective elastic bar 24 and snapped into
a respective one of the two snap holes 20 of the respective elastic
bar 24. The second end of each of the auxiliary pulling ropes 450
is provided with a snap hook 470 snapped on the respective snap
hook 44 of the pulling belt 41. In such a manner, each of the two
auxiliary pulling ropes 450 and the respective pulling rope 45 are
mounted between the respective elastic bar 24 and the elastic
pulling belt 41, so that the force applied by each of the auxiliary
pulling ropes 450 and each of the two pulling ropes 45 has the same
direction. Thus, the body exercising device 10 can provide forces
of different strength on the user, thereby satisfying the
requirements of different users.
[0039] Accordingly, the body exercising device 10 is available for
users of different stature and height, thereby greatly enhancing
the versatility of the body exercising device 10. In addition, the
body exercising device 10 can provide forces of different strength
on the user, thereby satisfying the practical requirements of
different users. Further, each of the elastic bars 24 can provide a
smaller restoring force on the user, thereby preventing the user
from being hurt due to an excessive restoring force. Further, the
elastic bars 24 can co-operate with the pulling devices 40 to
exercise different parts of the user's upper body, such as the
user's two hands, chest muscle, abdominal muscle and back muscle,
thereby enhancing the versatility of the body exercising device
10.
[0040] 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
