the user to exercise indoors. A conventional treadmill, as shown in
FIG. 6, includes a bottom bracket 61, a standing bracket 62 stood
on the bottom bracket 61, and the standing bracket 62 is assembled
with a handlebar 63. The bottom bracket 61 is assembled with a
treadmill platform 64 for a user to run thereon. Specifically, to
increase the training strength, a driving unit 65 is assembled
between the bottom bracket 61 and the treadmill platform 64 for
lifting the treadmill platform 64 to increase the slope of the
treadmill platform 64. Therefore, the treadmill can simulate the
uphill scenario for the user when the user runs on the
treadmill.
[0003] However, when the treadmill platform of the conventional
treadmill is lifted, the distance between the user on the treadmill
and the handlebar is increased. As a result, the user cannot hold
the handlebar conveniently. Hence, when the user runs on the
treadmill, the user might fall on the treadmill, adversely
affecting the user's safety.

of the standing bracket wheat the slope of the treadmill platform
is changed. Therefore, when the user runs on the treadmill, the
safety of the user is improved.
[0005] In view of this, a treadmill is provided and comprises a
bottom bracket assembled with a standing bracket extending upward,
and the standing bracket being assembled with a handlebar; a
movable unit movably connected on the standing bracket, a driving
unit being assembled with the bottom bracket for driving the
movable unit to slide along an extension direction of the standing
bracket; and a treadmill platform having a front end and a rear
end, the front end being pivotally connected on the movable unit,
so that the front end is moved along with a movement of the movable
unit at the same time.
[0006] Wherein, the movable unit is slidable along the standing
bracket to a position higher and lower than a height of the rear
end.
[0007] In one embodiment, the movable unit is a sleeve fitted over
an outer periphery of the standing bracket.

DETAIL PORTIONED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0015] Please refer to FIG. 1, illustrating a treadmill according
to the present invention. The treadmill has a bottom bracket 1
assembled with a standing bracket 2 extending upward. The standing
bracket 2 comprises two elongated bars 21 respectively assembled at
the right and left sides of the bottom bracket 1. A handlebar 22 is
assembled on the top of each of the elongated bars 21. In this
embodiment, a bottom end of the standing bracket 2 is pivotally
connected to the bottom bracket 1. Therefore, the standing bracket
2 can be swung relative to the bottom bracket 1, and the tilt angle
of the standing bracket 2 is adjustable.
[0016] Furthermore, a movable unit 3 is assembled on each of the
elongated bars 21 of the standing bracket 2, and the bottom bracket
1 is assembled with a driving unit 4. The driving unit 4 can drive
each of the movable units 3 to slide along the extension direction
of the corresponding elongated bar 21. The movable unit 3 may be
connected with the elongated bar 21 in different ways. In one
embodiment, as shown in FIG. 1, the movable unit 3 is a sleeve
fitted over an outer periphery of the elongated bar 21, and the
movable unit 3 is driven by the driving unit 4 to slide along the
extension direction of the elongated bar 21. In another embodiment,
as shown in FIG. 2, the movable unit 3 is a slider, and the
elongated bar 21 is assembled with a rail 211 extending along the
extension direction of the elongated bar 21. The movable unit 3 is
slidably assembled on the rail 211 and is driven by the driving
unit 4 to slide along the rail relative to the elongated bar
21.
[0017] Moreover, the two movable units 3 on the two elongated bars
21 are fixed and connected with each other by a transversal bar 31,
and the driving unit 4 is connected to the transversal bar 31. In
addition, the driving unit 4 drives the movable units 3 to move by
pushing, so that the movable units 3 can be moved at the same
time.
[0018] Furthermore, the present invention further comprises a
treadmill platform 5 for a user to run thereon. The treadmill
platform 5 has a front end 51 and a rear end 52, the left and right
sides of the front end 51 are pivotally connected with the two
movable units 3, respectively, and the rear end 52 is assembled
with a wheel 53 for rolling against the ground. In another
embodiment shown in FIG. 3, the bottom bracket 1 is extending
toward the rear end 52 of the treadmill platform 5, so that the
wheel 53 can roll against the bottom bracket 1.
[0019] Accordingly, in the present invention, the aforementioned
components are applied to lift the treadmill platform 5 so as to
change the slope of the treadmill Therefore, the training strength
provided by the treadmill can be changed when the user runs on the
treadmill. In detail, as shown in FIG. 4, when the driving unit 4
is in operation, the driving unit 4 pushes the transversal bar 31
to move the movable units 3, so that each of the movable units 3 is
moved along the extension direction of the corresponding elongated
bar 21. Since the front end 51 of the treadmill platform 5 is
connected to the movable units 3, the front end 51 of the treadmill
platform 5 is moved by the movable units 3 and the slope of the
treadmill platform 5 is changed.
[0020] The slope of the treadmill platform 5 is determined by the
difference between the height of the front end 51 and the height of
the rear end 52. As shown in FIG. 4, it is defined that the rear
end 52 of the treadmill platform 5 has a reference height H, and
the movable unit 3 can be moved to a position higher than the
reference height H when the movable unit 3 is driven to move along
the elongated bar 21, so that the front end 51 of the treadmill
platform 5 is higher than the rear end 52 of the treadmill platform
5. Therefore, the treadmill platform 5 provides an uphill scenario
for the user; in this case, the standing bracket 2 can be adjusted
to swing toward the treadmill platform 5, so that the handlebar 22
comes close to the treadmill platform 5. Conversely, as shown in
FIG. 5, the movable unit 3 may be driven to move along the
elongated bar 21 to a position lower than the reference height H,
so that the front end 51 of the treadmill platform 5 is lower than
the rear end 52 of the treadmill platform 5. Therefore, the
treadmill platform 5 provides a downhill scenario for the user; in
this case, the standing bracket 2 can be adjusted to swing away
from the treadmill platform 5, so that the handlebar 22 goes away
from the treadmill platform 5. Accordingly, the treadmill can allow
the treadmill platform 5 to have different slopes to meet different
training requirements.
[0021] According to the aforementioned components, when the
treadmill platform 5 is adapted to simulate the uphill scenario,
the user is lifted by the treadmill platform 5, so that the user
leans backward; in this case, the standing bracket 2 is adjusted to
swing toward the treadmill platform 5, so that the handlebar 22
comes close to the user and spaced from the user by a proper
distance. Conversely, when the treadmill platform 5 is adapted to
simulate the downhill scenario, the user leans forward; in this
case, the standing bracket 2 is adjusted to swing away from the
treadmill platform 5, so that the handlebar 22 goes away from the
user and spaced from the user by a proper distance.
[0022] Based on the above, the feature of the embodiment of the
present invention is that the front end 51 of the treadmill
platform 5 is connected with the movable units 3 that are capable
of being moved upward and downward along the standing bracket 2.
Therefore, when the treadmill platform 5 is lifted or descended,
the front end 51 of the treadmill platform 5 is always connected to
the standing bracket 2. In addition, the standing bracket 2 can be
swung relative to the bottom bracket 1 to adjust the position of
the handlebar 22. Therefore, the distance between the user on the
treadmill platform 5 and the handlebar 22 does not change.
[0023] Accordingly, the user can conveniently hold the handlebar 22
no matter what the slope of the treadmill platform 5 is, thus
improving the safety for the operation of the treadmill and
reducing the occurrence of accidents.
