Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates generally to a training
machine, and more particularly to a multifunctional sitting type
elliptical trainer.
[0003] 2. Description of the Related Art
[0004] There are various types of training machine in the market to
train different muscles. Typically, a specific training machine
mainly trains a specific group of user's muscles. However, if the
path of motion does not meet the natural motion of human when user
gets train on the training machine, it might hurt the user.
[0005] For a conventional training machine with two pedals and two
handles, the pedals are connected to the handles through linkages.
The handles are moved by the pedals that user may train his/her
legs and arms when user holds the handles and steps on the pedals.
The pedals of such training machine only provides a curved path of
motion that user only may step on the machine, not walk on the
machine, so that the loading is concentrating on fewer muscles of
legs when the user steps on the pedals. It will quickly overloads
the muscles that user may not take exercise on the machine for a
long time.
[0006] Another conventional elliptical training machine provides an
elliptical path of motion for feet. However, user has to stand on
the machine to take exercise. Some elliptical training machines are
provided with a seat that user may sit on it to take exercise.
However, the path of motion when user sits to take exercise does
not meet the natural motion that such training machine still has
above drawbacks.
SUMMARY OF THE INVENTION
[0007] The primary objective of the present invention is to provide
a multifunctional elliptical trainer, on which user may sit to take
exercise in a path of motion close to natural motion.
[0008] According to the primary objective of the present invention,
a multifunctional elliptical trainer includes a frame, a seat, a
leg training apparatus, and a hand training apparatus. The frame
has at least roller rail. The seat is provided on the frame. The
leg training apparatus includes a flywheel provided on the frame,
two pedal bars, on each of which a pedal is provided, having ends
pivotally connected to the flywheel, and having rollers to be
engaged with the roller rail of the frame that the pedal bars slide
along the roller rail. The hand training apparatus has two handles,
each of which has a holding portion, pivoted on the frame and two
linkages having opposite ends pivotally connected to the handles
and the pedal bars respectively.
[0009] User may sit on the seat, holds the handles, and steps on
pedals of the pedal bars to train his/her legs and arms in the same
time. The paths of motions of arms and legs are similar to the
natural paths that user may take exercise for a long time in an
easy way.

DETAILED DESCRIPTION OF THE INVENTION
[0015] As shown in FIG. 5, an elliptical trainer 100 of the first
preferred embodiment of the present invention provides user to sit
on the trainer to train hands and legs. The path of motion of the
present invention is close to the natural path.
[0016] The elliptical trainer 100 includes a frame 10, a seat 20, a
leg training apparatus 30, and a hand training apparatus 40.
[0017] The frame 10 has several tubes connected together to stand
on the ground. The frame 10 includes two roller rails 12, a seat
rail 14 and a vertical tube 16. The wheel rails are parallel to
each other. The seat rail 14 is inclined. The vertical tube 16 is
in front of the seat rail 14 to mount a panel or other device
thereon.
[0018] The seat 20 is slidably connected to the seat rail 14 of the
frame 10 for reciprocation that user may move the seat 20 to change
a distance between the seat 20 and the vertical tube 16 according
to his/her body size.
[0019] The leg training apparatus 30 includes a flywheel 32, two
pedal bars 34 and two rollers 36. The flywheel 32 is under the seat
20 to be pivoted on the frame 10. The pedal bars 34 are at opposite
sides of the vertical tube 16, each of which has a straight section
34a and a bent section 34b.
[0020] The straight sections 34a of the pedal bars 34 are connected
to the flywheel 32 through cranks 38. Each of the pedal bars 34 is
provided with a roller 36 on the straight section 34a to be engaged
with the roller rail 12 respectively that the pedal bars 34 may
move forward (FIG. 3) or backward (FIG. 5) along the roller rails
12. It will move the bent sections 34b of the pedal bars 34 in
elliptical paths when the straight sections 34a reciprocate on the
roller rails 12. Each of the pedal bars 34 is provided with a pedal
35 on the bent section 34b.
[0021] An angle between the straight section 34a and the bent
section 34b is an obtuse angle, a preferred angle is in a range
between 100 degrees and 160 degrees that user may have an east
posture to sit on the seat 20 and step on the pedals 35 to take
exercise on the elliptical trainer 100 of the present
invention.
[0022] The hand training apparatus 40 includes two handles 42 and
two linkages 44. The handles 42 have several bent portions and are
pivoted on the vertical tube 16 of the frame 10. Each of the
handles 42 has a holding portion 42a at an upper section and a
lower end pivotally connected to the bent section 34b of the pedal
bar 34 through the linkage 44 that a movement of the pedal bars 34
of the leg training apparatus 30 may drive the handles 42 of the
hand training apparatus 40 to swing. In other words, user may have
a curved path of motion of hands and an elliptical path of motion
of legs in the same time when he/she sits on the seat 20, holds the
holding portions 42a of the handles 42, and steps on pedals 35 of
the pedal bars 34.
[0023] When user sits on the seat 20, holds the holding portions
42a of the handles 42, and steps on pedals 35 of the pedal bars 34,
he/she may have paths of leg and hand motions similar to the
natural paths that user may not get hurt when he/she takes exercise
on the trainer 100 of the present invention, and furthermore, user
may take exercise for a long time.
[0024] FIG. 6 shows an elliptical trainer of the second preferred
embodiment of the present invention, which is similar to the
elliptical trainer 1 of the first preferred embodiment, except that
a pedal 50 is pivoted on the pedal bar 34 and two springs 52 are
provided between the pedal 50 and the pedal bar 34. The springs 52
urge the pedal 50 to contact user's foot all the time when the
steps on the pedal 50.
[0025] FIG. 7 shows an elliptical trainer of the third preferred
embodiment of the present invention, which is similar to the
elliptical trainer 1 of the first preferred embodiment, except that
a handle 60 has an operating bar 62, a holding bar 64, and a knob
66. The operating bar 62 has a vertical section 62a to be the
holding portion. The holding bar 64 is pivoted on the operating bar
62, and the knob 66 may be turned to fasten or to loose the holding
bar 64. User may choose to hold the vertical sections 62a of the
operating bars 62 in a vertical posture or hold the holding bars 64
(FIG. 7) in a horizontal posture (FIG. 8), and he/she may turn the
knob 66 to loose the holding bars 64 for rotation (FIG. 9) or to
fasten the holding bar 64 (FIG. 8).
[0026] The description above is a few preferred embodiments of the
present invention. These equivalences of the present invention are
still in the scope of claim construction of the present
invention.
