ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to an exercise machine, and more particularly to a gripping structure of the exercise machine.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a chest building machine
1
of the prior art comprises two operation rods
2
and two curved handles
3
which are fastened with the operation rods
2
for holding fast with hands of an exerciser seated on a seat of the machine. As the handles
3
are pushed forward, the weights
4
are lifted by a steel cable for building the triceps of the upper arms and the pectoral muscle of the chest of the exerciser. Another prior art exercise machine
5
is shown in FIG.
2
and is mainly composed of a pull cord
6
which is connected at one end thereof with a cross rod which is provided with a handle
7
fastened therewith such that the weights
8
can be lifted by a cord fastened with the cross rod at the time when the handle
7
is gripped with hands of an exerciser to actuate the cross rod. The machine
5
is intended for building the latissimus dorsi and the humerus muscle. In addition, the operation rod
9
is provided with two handles
901
and
902
parallel to each other and perpendicular to the operation rod
9
for use in building muscles of specific parts of a human body. The handles
3
,
901
and
902
of the prior art exercise machines
1
and
5
are fixed. As a result, one must use a variety of exercise machines to build the muscles of various parts of the body in view of the fact that the effect of the muscle-building exercise depends on the way that the hands grip the handles of the exercise machine.
SUMMARY OF THE INVENTION
The primary objective of the present invention is therefore to provide an exercise machine with a versatile gripping structure enabling an exerciser to hold the gripping structure in various manners so as to do exercises for developing muscles of different parts of the body of the exerciser.
In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a gripping structure which is fastened at the top end of an operation rod of an exercise machine and is mainly composed of one or more frames and one or more gripping members equal in number to the frame. The frame is formed of two parallel rails which extend from the top end of the operation rod such that the two rails are perpendicular to the operation rod. The gripping member is slidably disposed in the frame such that the gripping member can be moved away from or toward the operation rod, and that the gripping member can be rotated.
