ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a swing machine having a wave-shaped slot such that the support member moves in various directions.
BACKGROUND OF THE INVENTION
A conventional swing machine is shown in FIG.
7
and includes a motor
71
whose output shaft
711
is eccentrically connected to a block
72
. A sliding member
73
is movably engaged with two rods
74
and the block
72
has a protrusion
722
which is engaged with the sliding member
73
. A support member
75
is connected to the sliding member
73
so that when the motor
71
is in operation, the block
72
drives the sliding member
73
to move in a horizontal direction. A use may put his/her feet on the support member
75
and the muscles of the feet can be relaxed by the swing of the support member
75
. However, the way of swing does not change and is boring for the users so that the market expects new generation of the swing machine that may generate various ways of swing to effectively relax the muscles of the feet of users.
