ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to a complex exerciser structure, and more particularly to a versatile exerciser which is able to train the muscles of various parts of human body. The exerciser can be freely changeably assembled to meet the requirements of different users.
There are various conventional exercisers. Most of these exercisers are designed for exercising and training the muscle of a specific portion of human body. For example, there are exercisers for training the back muscle, abdomen muscle, arm muscle, leg muscle, etc.
FIGS. 10 and 11
show a conventional exerciser having an I-shaped base frame
50
, a support beam
51
and a seat pad
52
locked on the support beam
51
. One end of the support beam
51
is fixedly disposed with an upright stem
53
through which step rods
54
fitted with soft sleeves are passed. The other end of the support beam
51
is connected with a retaining beam
55
on which a back pad
56
is fixedly mounted. An end of the back pad
56
is disposed with two inclinedly extending handles
58
parallel to each other. The support beam
51
is connected with the retaining beam
55
via two parallel circular rods
57
, whereby the retaining beam
55
is movable relative to the support beam
51
. The above exerciser is able to exercise the muscle of a specific part of the user's body. However, such exerciser has only single function without other additional exercising effect. Therefore, in the case that the user needs to exercise the muscle of other parts of his/her body, he/she must purchase various exercises with different functions to achieve versatile exercising effects. This is not economical. Also, it will be inconvenient for the user to store various kinds of exercisers which will inevitably occupy much room.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a complex exerciser structure in which the back lever and the pull lever can be independently or relatively operated to provide versatile exercising effect for various parts of human body.
The present invention can be best understood through the following description and accompanying drawings wherein:
