allowing user to perform exercises similar to running and jogging
while avoiding the vibration caused by impinge and resulting in
burden to joints. However, there are several ways to drive the
direction, height, or angle of the stepping boards. Some install
weight distribution wheel at chosen place, and linking cranks are
installed on both sides of the weight distribution wheel. The
stepping boards are then connected to the cranks and hence could
cause feet exercise alternatively. Others install a bobbing rod on
both sides of the erecting pole of the machine. The stepping boards
are respectively pivoted at the bottom of the bobbing pole. Hence
when stepping on the stepping boards the legs could exercise due to
the swinging motion. Still there is a treadmill install a curved
single rail before assembling the stepping boards on the rail
presenting sliding motion so that user could step on it and
exercises.
[0005] The above mentioned many treadmills of different kinds of
structures. Their common problem is in that user cannot perform
running exercise, particularly the sing curved rail and the
swinging exercise structures that can only allow user to swing the
leg. The muscles on the feet and legs could not exert force and
therefore hard to achieve the effect of real exercise. Whereas the
treadmill installed with weight distribution wheel has complicated
structure that is not only difficult to store away but also costs
dearly.

rope 118 is hooked to the bottom of the stepping board 3, so that
the sliding mode of the two stepping boards 3 is restrained by the
pulling rope 118 (such as shown in FIG. 6 and FIG. 7) presenting
the to and fro sliding movement. In this way, the stepping board 3
is slanting at an ergonomic angle and when the front and rear
rollers 32 & 32' are rolling on the upper and lower rail bards
211 & 212 the stepping board 3 can vary its angle according to
the above stated guiding section 211A & 212A so that when the
user is stepping on the machine the naturally running movement
could meet the ergonomic action (as shown in FIG. 7).
[0022] As shown in FIG. 1 & FIG. 3, the two handrails 4 can be
of steel or other piping material, consisting of a holding section
41 bending at the upper section and a pivoting section 42 close to
the bottom end; the two handrail 4 pivoting section 42 is pivoted
to the pivoting board 112 on the two sides of the front base 11 in
the form of rotating state, and at the location close to the
pivoting section 42 a fast rotating fixture 43 is installed so that
the handrail 4 can be fixed at a proper angle. And at the selected
symmetrical section of the handrail 4 can be connected with a
lateral bar, the body of the lateral bar 44 is installed with two
pivoting base 441 for connecting to the rocking pole described
below.
[0023] FIG. 1 & FIG. 3 show two rocking poles 5. Each of the
rocking pole 5 are both made of steel pipe of other pipe material;
the body of the rocking pole 5 is installed with a pivoting part
51, wherein the pivoting part 51 is connected to the pivoting base
441 of the lateral bar 44 stated above to form swinging state; the
upper section of the rocking pole 5 is a holding section 52,
whereas close to the bottom end each is installed with a pulling
strip 53 of metallic material, so that one end of the pulling strip
53 is pivoted to the rocking pole 5 and the other end is pivoted to
the bottom of the stepping board 3, so that the two rocking pole 5
and the two stepping boards 3 constitute linking action. When the
hand is holding the holding section 52 of the rocking pole 5 and
the feet are stepping on the stepping boards 3 for sliding action
the effect of arm swinging action while running can be created (as
shown in FIG. 7).
[0024] With the above structural characteristic design of base 1,
sliding rail set 2, stepping board 3, handrail 4, and rocking pole
stated above, particularly the structure of the said two sliding
rail set 2 and stepping board, the fitness treadmill of the present
invention is created, allowing user to engage in the indoor running
exercise. As the sole of the foot palm is always in contact with
the stepping board 3 when using the present invention, unlike the
conventional treadmill where the foot might knock against the
track, therefore the burden of the knee and ankle joint could be
avoided and the sport injury can be prevented. In particular, each
sliding rail 21 of the two sliding rail set 2 of the present
invention consists of an upper rail strip 211 and a lower rail
strip 212. Therefore, the design of the present invention is not
only in the light and simple structure and relatively more economic
in manufacturing cost but also in bent-knee stepping exercise that
could further manifest the performance of fitness exercise. More
over, as the rocking pole of the present invention can be pivoted
to the lateral bar 44 and the lateral bar 44 can be connected to
handrail. The said handrail 4 adopts the method of pivot connection
to the front base 11 close to the bottom, hence after loosening of
fast rotating fixture 43 the two handrail 4 and the two rocking
pole 5 could be folded back (as shown in FIG. 5) in order to reduce
its size for the ease of storage.
[0025] In addition, the characteristic of the present invention is
in that the structure of the said two sliding rail set 2 and the
structure of stepping board 3 and assembly style design. However,
the embodiment is not limited to the above examples and could also
change its shape according to the need of the exercise, etc. As
shown in FIG. 8, the front section of the said rail strip 211 can
be installed as the first guiding section 211B with the shape
bending upward, whereas the rear section can also be installed as
the second guiding section 211C bending upward; also, the front
section of the lower rail strip 212 constitutes the first guiding
section 212B with the same curve, whereas the rear section of the
second guiding section 212C is horizontal. In this way the stepping
board 3 assembled according to above example can generate another
running action effect (such as the angle of the two steeping board
3 shown in FIG. 8); or as shown in FIG. 9 the assembly method of
the said steeping board 3 also can be changed to rear roller 32'
pressed against the lower rail strip 212, wherein the structure of
the front roller 32 pressing against the upper rail strip 211 can
also achieve the same effect as the above stated structure.
