ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to an exerciser in which the seat pad and the base frame can be swung, lifted and lowered and the angle of the handle can be freely adjusted. Therefore, the position of the handle can be adjusted in accordance with various conditions with the user's body stably pressing on the seat pad and the, base frame. A resilient section of the handle creates a resilient force, when pushing and pulling the handle so as to achieve an exercising effect.
FIG. 6
shows an existing exerciser composed of large and small U-shaped frames
90
,
91
which are pivotally connected with each other at two ends. The pivot sections
92
,
93
are adjustable in angle and interconnected by a transverse beam
94
. Each lateral side of the large frame
90
is disposed with a resilient section
95
,
96
. Each end of the transverse beam
94
is equipped with a shoulder belt
97
,
98
.
Referring to
FIG. 7
, in a sit-up exercise, a user presses his/her body against the transverse beam
94
and fits the shoulder belts
97
,
98
around the knees. The user also steps on the small frame
91
with his/her soles and pulls the large frame
90
. During the sit-up exercise, the resilient sections
95
,
96
create a resistant force to achieve a training effect.
According to the above arrangement, the user must first lean the respective parts of his/her body against the small frame
91
and tranrseverse beam
94
and fit the shoulder belts
95
,
96
around the knees and then pull the large frame
90
for exercising his/her body. However, different users have varied body configurations, while the large and small frames
90
,
91
have fixed sizes. Therefore, it often takes place that some users can hardly suitably use the exerciser and they are subject to injury.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an exerciser including a base frame and a leg support pivotally inward foldably connected with two ends of a bottom face of the base frame, The leg support has a front arch section and a rear horizontal section, enabling a user to swing, lift and lower the base frame. Two ends of a rear side of the base frame are respectively disposed with two adjustment seats for freely adjusting the angle of the handles The position of the handle can be adjusted in accordance with various conditions for the user with the~user's body stably pressing on the seat pad and the base frame. A resilient section of the handle creates a resistant force when pushing and pulling the handle so as to achieve an exercising effect.
It is a further object of the present invention to provide the above exerciser in which the length of the handle is adjustable in accordance with the body configurations of different users so that the user can suitably hold the handle to exercise by various actions.
The present invention can be best understood through the following description and accompanying drawings, wherein:
