ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to an improved exerciser structure which includes ring sections and a torque generating means which enable a user to fold the exerciser structure with less strength. In addition, the stress exerted onto the pivot section of the exerciser structure is evenly distributed. The exerciser structure can be alternatively folded by an electric folding measure as necessary.
FIGS. 1 and 2
show a conventional running exerciser which includes a base seat
91
, a rail
92
and a running belt assembly
93
. The running belt assembly
93
includes a frame body
931
, two rollers
932
, a running belt
933
, an auxiliary pneumatic cylinder
934
, a motor
935
for driving the running belt
933
and a pivot shaft
936
. After used, the running belt assembly
93
is turned from a first position P
1
to a second position P
2
for saving room.
The above running exerciser has a shortcoming, that is, the pivot shaft
936
suffers a concentrated stress so that the pivot shaft
936
is apt to be damaged. Furthermore, after a long period of use, the auxiliary pneumatic cylinder
934
tends to fail due to leakage of air. Also, the conventional running exerciser cannot be folded by electrical measure.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an improved exerciser structure in which the stress exerted onto the pivot section of the exerciser structure is evenly distributed without concentration. Therefore, the using life of the exerciser structure is prolonged.
It is a further object of the present invention to provide the above improved exerciser structure in which a torque generating means is used instead of the conventional auxiliary pneumatic cylinder so as to eliminate the problem of leakage of air of the pneumatic cylinder.
It is a further object of the present invention to provide the above improved exerciser structure which can cooperate with an electrically folding measure as the torque generating measure so that the function of the exerciser can be easily advanced and the exerciser can be electrically folded.
According to the above objects, the exerciser structure of the present invention includes:
a fixed unit having a base section, a rail section upward extending from the base section and a control panel; and
a movable unit having a frame body on which an exercising device is disposed.
The frame body of the movable unit further includes a pair of ring sections. One of the ring sections is fixed with a torque generating means. Each of the ring sections has an inner circumference and an outer circumference.
The base section of the fixed unit is disposed with a fixing board on which an inner guide wheel and multiple outer guide wheels are rotatably disposed. The inner guide wheel tightly contacts with the inner circumference of the ring section. The outer guide wheels tightly contact with the outer circumference of the ring section, whereby the ring section can rotate stably and the movable unit can rotate on the fixed unit between a substantially horizontal first position prior to folding and a substantially vertical second position after folded.
