Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a pedaling wheeled exerciser, more
particularly to a pedaling wheeled exerciser which permits
exercising of the arms and legs.
[0003] 2. Description of the Related Art
[0004] Referring to FIG. 1, a conventional pedaling wheeled
exerciser 10 is shown to include a frame body 11, a seat 12 mounted
on a rear end of the frame body 11, and a crank and pedal assembly
13 and a handgrip crank 14 respectively and rotatably mounted on
lower and upper ends of the frame body 11 to be operated by the
user's feet and hands for exercising the same. A resistance unit
(not shown) is disposed on the frame body 11 to generate a
resisting force against the rotation of the crank and pedal
assembly 13 operated by the user's feet so as to exercise the
user's legs. However, since no resisting force is applied to the
handgrip crank 14, the arm exercising effect is poor. If an
additional resistance unit is coupled with the handgrip crank 14,
this will result in increased manufacturing cost. On the other
hand, if the resistance unit coupled with the crank and pedal
assembly 13 is also coupled with the handgrip crank 14, the
handgrip crank 14 and the crank and pedal assembly 13 will be
operated simultaneously, which may not be desirable in use.
SUMMARY OF THE INVENTION
[0005] The object of the present invention is to provide a pedaling
wheeled exerciser in which leg and arm exercising units can be
operated individually or together, and are rotated against a
predetermined resisting force of a resistance unit so as to provide
an enhanced exercising effect for the user's arms and legs.
[0006] According to this invention, the pedaling wheeled exerciser
includes a base frame, a crank axle mounted on and rotatable
relative to the base frame about a first axis, a crank and pedal
assembly disposed to rotate the crank axle, a first wheeled body
surrounding and rotatable relative to the crank axle, a first
unidirectional member disposed to couple the crank axle with the
first wheeled body such that the first wheeled body is driven to
rotate about the first axis in a clockwise direction only when the
crank axle is rotated in the clockwise direction, a resistance unit
disposed to generate a resisting force against the rotation of the
first wheeled body, an upright post extending uprightly from the
base frame to terminate at an upper end, a hand operated wheel
rotatably mounted on the upper end of the upright post about a
second axis parallel to the first axis, a second wheeled body
mounted to be rotatable relative to the crank axle about the first
axis, a force transmitting member disposed to couple the hand
operated wheel with the second wheeled body so as to transmit a
rotational force of the hand operated wheel to rotate the second
wheeled body about the first axis, and a second unidirectional
member disposed to couple the first and second wheeled bodies such
that a rotational force generated as a result of the rotation of
the second wheeled body is transmitted to the first wheeled body
only when the second wheeled body is rotated in the clockwise
direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] Referring to FIGS. 2 and 3, the preferred embodiment of a
pedaling wheeled exerciser according to the present invention is
shown to comprise a frame body 20, a leg exercising unit 30, an arm
exercising unit 40, a resistance unit 50, and a transmitting unit
60.
[0018] The frame body 20 includes a base frame 21, an upright post
22 welded to the base frame 21 and extending uprightly from the
base frame 21 to terminate at an upper end, a seat frame 23
extending rearwardly from the base frame 21 to terminate at a rear
end, and a seat 24 adjustably mounted on the rear end of the seat
frame 23. The base frame 21 includes a base 211, a pair of U-shaped
racks 212 (only one is shown) secured on the base 211, and an
upright support 213 extending uprightly from the base 211. Two
bearing seats 214 are respectively secured on front portions of the
racks 212. A front post sleeve 25 is sleeved on the upright post
22, and has a display panel 26 disposed thereon. The seat frame 23
has a support leg 231 for standing on a floor surface, and a seat
mounting shaft 232 extending uprightly such that the seat 24 has a
mounting portion 241 slidably mounted on the seat mounting shaft
232 and locked by a screw fastener 242.
[0019] Referring to FIGS. 2 to 5, the leg exercising unit 30 is
mounted on the base frame 21, and includes a crank axle 31
supported on the bearing seats 214 so as to be rotatable relative
to the base frame 21 about a first axis, and a crank and pedal
assembly 32 disposed to rotate the crank axle 31 and having a crank
321 and two pedals 322.
[0020] The arm exercising unit 40 is disposed on the upper end of
the upright post 22, and includes a hand operated wheel 41
rotatable relative to the upright post 22 about a second axis
parallel to the first axis, and a handgrip crank 42 disposed to
rotate the hand operated wheel 41.
[0021] The resistance unit 50 is disposed on the base frame 21
adjacent to the leg exercising unit 30, and includes an axle shaft
51 which is mounted on and which is rotatable relative to the
upright post 213 about a third axis parallel to the first axis of
the crank axle 31, and which has a plurality of teeth 511 formed
thereon, a resistance wheel 52 which is disposed to be rotated with
the axle shaft 51, and a resistance regulator 53 (see FIG. 4) which
is disposed to regulate the resistance force of the resistance
wheel 52.
[0022] The transmitting unit 60 includes first and second wheeled
bodies 61, 64 respectively surrounding first and second ends of the
crank axle 31 which are opposite to each other along the first
axis, first and second unidirectional members 62, 65, and first and
second force transmitting members 66, 67. The first wheeled body 61
has a first wheel which is rotatable relative to the crank axle 31
and which has a plurality of teeth 611 formed thereon, and a first
tubular coupler 63 which is connected to and which extends from an
inner periphery 612 of the first wheel along the first axis towards
the second wheeled body 64. The first unidirectional member 62 is
in the form of a ring, such as a unidirectional ball bearing, and
is disposed to couple the first wheeled body 61 with a collar 311
on the first end of the crank axle 31 such that the first wheeled
body 61 is driven to rotate about the first axis in a clockwise
direction only when the crank axle 31 is rotated in the clockwise
direction. The first force transmitting member 66 is a transmitting
belt which is trained on the first wheel of the first wheeled body
61 and the axle shaft 51 and which is engaged with the teeth 611,
511. The second wheeled body 64 includes a second wheel surrounding
the crank axle 31, and a second tubular coupler 642 which extends
from an inner periphery of the second wheel along the first axis,
which is surrounded by and which is spaced apart radially from the
first tubular coupler 63 with an annular space therebetween, and
which has an outer annular groove 641 formed in an outer periphery
thereof. The second force transmitting member 67 is a transmitting
belt which is trained on the hand operated wheel 41 and the annular
groove 641 in the second wheeled body 64 so as to transmit a
rotational force of the hand operated wheel 41 to rotate the second
wheeled body 64 about the first axis. The second unidirectional
member 65 is in the form of a ring, such as a unidirectional ball
bearing, is received in the annular space, and couples the second
tubular coupler 642 with the first tubular coupler 63 such that a
rotational force generated as a result of the rotation of the
second wheeled body 64 is transmitted to the first wheeled body 61
only when the second wheeled body 64 is rotated in the clockwise
direction.
[0023] With reference to FIGS. 5 and 6, when the user treads the
pedals 322 to rotate the crank axle 31 in the clockwise direction
in a leg exercising operation, the first wheeled body 61 is rotated
in the same direction by means of the first unidirectional member
62 such that the transmitting belt 66 drags the resistance wheel 52
to rotate with the first wheeled body 61 against the resisting
force. With reference to FIG. 7, in this state, even when the first
wheeled body 61 is rotated in the clockwise direction, the second
tubular coupler 642 is not rotated with the first wheeled body 61
because of the provision of the second unidirectional member 65,
whereby the arm exercising unit 40 is not operated so as not to
interfere with the leg exercising operation.
[0024] With reference to FIGS. 5 and 8, when the user rotates the
handgrip crank 42 with the hands to rotate the hand operated wheel
41 in the clockwise direction in an arm exercising operation, the
second wheeled body 64 is rotated in the same direction by means of
the transmitting belt 67. Meanwhile, the first wheeled body 61 is
rotated with the second wheeled body 64 by means of the second
unidirectional member 65 such that the resisting force is applied
to the hand operated wheel 41 through the transmitting belts 66, 67
and the first and second wheeled bodies 61, 64. With reference to
FIG. 9, in this state, even when the first wheeled body 61 is
rotated in the clockwise direction, the crank axle 31 is not
rotated with the first wheeled body 61 because of the provision of
the first unidirectional member 62, whereby the leg exercising unit
30 is not operated so as not to interfere with the arm exercising
operation.
[0025] According to this invention, the handgrip crank 42 and the
crank and pedal assembly 32 can be operated individually or
together and can be rotated against a predetermined resisting force
of the resistance unit 50 so as to provide an enhanced exercising
effect for the user's arms and legs.
[0026] While the present invention has been described in connection
with what is considered the most practical and preferred
embodiment, it is understood that this invention is not limited to
the disclosed embodiment but is intended to cover various
arrangements included within the spirit and scope of the broadest
interpretations and equivalent arrangements.
