Description
FIELD OF THE INVENTION
[0001] The present invention relates to an elliptical exerciser,
especially for an adjustable post which changes the positions of
the elliptical trace of the pedals so as to obtain different modes
of exercising conditions.
BACKGROUND OF THE INVENTION
[0002] People take exercise to keep a good physical condition by
jogging, swimming, or oxygen-gained exercises. The exercises
consume calories, increase the strength of muscles and reduce fat.
Nevertheless, outdoors exercises are easily affected by the
temperature and/or the climate, so that many people prefer to take
exercise indoor such as weight lifting, treadmills, stationary bike
or stepping machine. The elliptical exercisers involve many actions
such as walking, stepping, pushing, and pulling so as to reinforce
the durability and strength of muscles on legs, waist, hips and
arms. The elliptical machine occupies less space and can be used in
any places and in any time.
[0003] Referring to FIG. 1, a conventional elliptical machine 90
includes an upright post 91 and two handles 92, two foot pedal rods
93 and a disk 94. The handles 92, the foot pedal rods 93 and the
disk 94 are pivotably with each other. When the user stands on the
foot pedal rods 93 with his or her hands holding the handles 92 and
pivots the two handles 92 back and forth alternately as shown by
the arrow head "A", the disk 94 rotates as shown by the arrow head
"B", and the pedal foot pedal rods 93 are moved along an elliptical
trace as shown in the arrow head "C". Nevertheless, the positions
of the foot pedal rods 93 cannot be adjusted and the position of
the elliptical trace is not adjustable accordingly. In other words,
only the fixed part of the muscles is exercised and this makes the
user feel boring by the fixed mold of exercise and also makes the
user feel boring by the fixed mold of operation. Not as hiking, the
road conditions change all the time, some time the road goes upward
and some time downward, this brings different exercises for
different parts of the muscles.
[0004] The present invention intends to provide an elliptical
exerciser wherein the elliptical trace can be changed according
different modes of exercising so as to meet different requirements
of the users.
SUMMARY OF THE INVENTION
[0005] The main object of the present invention is to provide an
elliptical exerciser and the inclination of the pedals can be
adjusted by adjusting the upright post so as to simulate different
types of exercising conditions and to exercise different parts of
muscles.
[0006] In order to achieve the object mentioned above, the present
invention provides an elliptical exerciser includes a base, a body,
a transmission device, an adjustable upright post, a pair of
handles and two foot pedal rods. The post is composed of an upper
tube which is retractably inserted in a lower tube. Two respective
mediate portions of the two handles are connected to two sides of
the upper tube. Two front ends of each foot pedal rod are
respectively connected to a lower end of each the handle and two
rear ends of each foot pedal rod are respectively connected to the
transmission device. A foot pedal board is provided on each foot
pedal rod. The swinging of the handles drives the foot pedal rods
and the transmission device rotates. The positions of elliptical
trace of the foot pedal boards are adjusted by adjusting the upper
tube upward or downward relative to the lower tube so as to
simulate uphill hiking and downhill hiking and exercise different
parts of muscles.
[0007] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0014] Referring to FIGS. 2 and 3, the elliptical exerciser 20 of
the present invention comprises a base 21 which is located beneath
the body 22 of the elliptical exerciser 20 so as to be put on the
floor and support the body 22. The base 21 includes two transverse
bars 211 connected to two ends thereof so as to put the exerciser
20 in a stable condition. The body 22 has a casing 23 therein
received a driving mechanism (not shown) which is avoided from dust
by the casing 23. A transmission device 24 is connected to a rear
end of the body 22 and is connected to the driving mechanism and
exposed outside of the casing 23. The transmission device 24 is
operated as circular movement to move the driving mechanism, in
this embodiment, the transmission device 24 includes two disks
which are connected at two respective centers thereof so as to
rotate simultaneously.
[0015] The elliptical exerciser 20 has an upright post 25 at a
front end thereof and the post 25 includes an upper tube 251 and a
lower tube 252 in which the upper tube 251 retractably inserted for
adjusting the height. A lower end of the lower tube 252 is fixed to
the base 21 of the body 22. Two handles 26 are respectively
pivotably connected to two sides of the upper tube 251 at two
respective mediate portions of the two handles 26. The upper tube
251 includes two extension rods 261 on the two sides thereof and
the two respective mediate portions of the two handles 26 are
connected to the outer peripheries of the two extension rods 261,
so that the two handles 26 are pivoted about the two extension rods
261.
[0016] The elliptical exerciser 20 has two foot pedal rods 27 on
two sides thereof and each foot pedal rod 27 has a front end
pivotably connected to a lower end of respective one of the two
handles 26 and a rear end of each of the two foot pedal rods 27 is
respectively connected to the transmission device 24. The two
respective rear ends of the pedal rods 27 are located close to the
periphery of the disks and symmetric to a center of the disks. In
other words, if one of the two respective rear ends is located at
the twelve o'clock position, the other rear end is located at the
six o'clock position.
[0017] A foot pedal board 271 is provided on each of the two foot
pedal rods 27 and includes a knurl surface so that the user will
not slip on the foot pedal board 271. When the user's feet stand on
the two foot pedal boards 271 and swings the two handles 26
alternatively, the foot pedal rods 27 move along in an elliptical
trace.
[0018] Referring to FIGS. 4A and 4B, if the upper tube 251 is
adjusted upward as shown by the arrow head "A" relative to the
lower tube 252, the front end of each of the foot pedal rods 27
tilts upward. On the contrary, when the upper tube 251 is retracted
into the lower tube 252, the front end of each of the foot pedal
rods 27 tilts downward. Accordingly, the positions of the
elliptical trace are adjusted along with the adjustment of the
upper tube 251. When the foot pedal rods 27 tilt upward, the
exerciser simulates an uphill hiking condition and exercises the
muscle of the legs. When the foot pedal rods 27 tilt downward, the
exerciser simulates a downward hill hiking condition and exercises
the muscle of the hips.
[0019] Referring to FIG. 5, the adjustment is made by a positioning
device 30 which is connected to the upper tube 251 or the lower
tube 252 so as to position the upper tube 251 relative to the lower
tube 252. The positioning device 30 includes a retractable pin 31
and a spring 33 is mounted to the pin 31 which is pulled outward
and disengaged from one of the holes 32 defined in the upper tube
251 such that the upper tube 251 can be freely moved relative to
the lower tube 252 till the pin 31 is engaged with another one of
the holes 32 in the upper tube 251. The positioning device 30
provide the user a simple and convenient device that position the
upper tube 251 in a short period of time. The positioning device 30
can be varied and moderated by any known mechanism.
[0020] Referring to FIGS. 2 and 3, a panel 40 and two end bars 50
are connected to a top of the post 25. The panel 40 displays
related information of the exerciser via the driving mechanism such
as the period of time that is used, the period of time to be used,
and the amount of calories to be consumed. The user may hold the
end bars 50 during operating the exerciser 20. A sensor (not shown)
can be connected to the end bars 50 and electrically connected to
the panel 40 so as to display the physical condition of the user
such as the pulse, the breath and the amount of calories that has
been consumed. The user thus acknowledges the information during
the operation of the exerciser 20.
[0021] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
