[TECHNICAL FIELD]
The present invention relates.to an arm and leg powered bicycle and
more particularly to an arm and leg powered bicycle which can have a much
higher speed due to the power of the arms in addition to that of the legs and
which can also be used for the arm exercise.
[BACKGROUND OF ART]
Generally, the bicycles have been used conveniently and widely from
old times as a transporting means which can run by causing the rear wheel to
rotate through pedaling with the help of only legs without consumption of any
fuel. Particularly recently the bicycle riding is favored by almost everyone as it
is recognized as one of sports beneficial to the health in step with the rising
interest in the health, because bicycles are not only free from the environment
pollution owing to the exhaust gases but also the pedal movement for pressing
the bicycle pedals corresponds to the aerobic exercise needed for the human
body.
The ordinary bicycle, however, are somewhat too deficient in the
propulsive force to be the long distance transporting means or mountaineer
bicycles. Therefore, the speed change gears have been mounted on bicycles to
increase the propulsive force and there has been proposed a plan to drive both
the front gear and the rear gear simultaneously. However, such bicycles mostly
failed to be put to practical use because of the unreliable operation and
1

considerable resistance in the power transmitting processes.
[DISCLOSURE OF INVENTION]
The present inventor was engaged intensively in developing a bicycle
capable of being powered by the arms in conjunction with the legs upon the
judgment that the ability to increase the speed of a bicycle and to help the arm
exercise at the same time by modifying the fixed handle levers in the ordinary
bicycles driven so far only by the feet power so as to be driven by the hands
would be a great help to the improvement in the health.
As the result, the present inventor has come to develope a new bicycle
with a safe and simple structure, in which bicycle the vertical movement of the
handle levers can be applied to the driving force of the rear wheel by embodying
the handle levers to be movable, still maintaining the overall balance of the
bicycle, and subsequently by causing the resulting movement to be transferred
to the pedal shaft so as to cooperate synchronously with the movement of the
pedals.
The object of the invention, corresponding to the provision of the
bicycle described last, is achieved according to an aspect of the invention by an
arm and leg powered bicycle, comprising handle levers, front wheel, rear wheel,
handle shaft, supporting frames connecting various parts, pedal shaft for
transferring the movement of the pedals to the rear wheel, front and rear
sprockets and a chain belt revolving around the sprockets, wherein an operating
means for vertically rotating the handle levers and a means for transferring the
rotating force of the handle levers to a pedal shaft are further provided and the
2

handle levers and the pedals are moved oppositely to each other to cause the
vertical rotation of the handle levers to cooperate synchronously with the
movement of the pedals, with the overall balance of the bicycle body maintained.
Preferably, the operating means for vertically rotating the handle levers
is composed of a handle rotation shaft provided vertically movably at the central
position of the straight line of handle levers, one or two operating rods
connected to the left side, right side or both sides of the handle levers, and a
handle rotation shaft support, and further the handle levers are provided so as to
be rotatable around the handle lever rotating shaft as the rotation center by the
operation of an actuating pin, said actuating pin being provided on the top of the
handle shaft, and the above-described means for transferring the rotating force
of the handle levers to a pedal shaft comprises a crank shaft connected to the
operating rod or rods and rotatable by the vertical movement of the operating
rod or rods, a rotating shaft inserted in the inner cavity of a lower supporting
frame connected to a handle shaft supporting member, said rotating shaft acting
to transfer the driving force of the handle levers to the pedal shaft, a flexible
joint provided at one end of the rotating shaft, a driving gear provided at the
other end of the rotating shaft, and a driven gear mounted on the circumference
of the pedal shaft and engaged with the driving gear to transfer the rotation
force to the pedal shaft.
According to another aspect of the invention, one end of the crank shaft
is connected to the flexible joint provided in the rotation shaft through a cut-out
groove provided in the handle shaft supporting member and the other end of the
crank shaft is connected to the handle rotation shaft support so as to allow for
3

the crank shaft to rotate in conjunction with the operating rod or rods in
accordance with the movement of the handle levers. Preferably, the crank shaft
is shaped with bends in the form of U or s depending on the number of the
rods for the smooth operation and also the crank shaft may be formed optionally
in a straight line, wherein a crank shaft gear and a rotating shaft gear are
mounted integrally therewith to transfer the torque produced at the handle
levers ultimately to the pedal shaft.

[BEST MODE FO CARRYING OUT THE INVENTION]
The present invention is described in detail below by referring to the
accompanying drawings.
Figs. 1 to 13 show the overall structure of the representative first
embodiment of arm and leg powered bicycle according to the invention and Figs.
14 to 18, as a variant of the embodiment shown in Figs. 1 to 13, show the
operative relation for the case where the operation rods as the operation means
for vertical turning of the handle levers ot the invention are mounted in number
of tv/o. Further, Figs. 19 to 23 show the third embodiment of the invention
illustrating a still other example of the crank shaft as the transmitting means for
the torque of the handle levers in the invention.
As described in detail in Figs. 1 and 2, the arm and leg powered bicycle
according to the invention comprises handle levers 6a and 6b, front and rear
wheel 1 and 2, and pedals 12a and 12b, as in the ordinary bicycles, and further
comprises a handle shaft 7 connected to the handle levers 6a and 6b and
connected also to the front wheel 1 via handle shaft supporting member 10a, and
a pedal shaft 19 for transferring the motion of the pedals 12a and 12b to the
rear wheel 2 together with front and rear sprockets 14a and 14b and a chain belt
13 circulating around the sprockets. Additionally, there are included a saddle
(not numbered) and several supporting frames 4a, 4b, 4c, 4d, 4e, 4f and 4g to
connect and support the above described members.
In addition, the arm and leg powered bicycle according to the invention
includes further the operative means A for the purpose of moving the handle
members 6a and 6b up and down, which means consists of a handle rotation
7

shaft 3, an operating rod 11 and a handle rotation shaft support 9, and the means
B for transmitting the rotating force of the handle levers 6a and 6b to the pedal
shaft 19, which means consists of a crank shaft 5, a rotation shaft 16, a flexible
joint 15, a driving gear 17 and a driven gear 18 combined to the pedal shaft 19.
The handle rotation shaft 3, which is located at the center of the handle
levers 6a and 6b to act as a fulcrum of the levers, is disposed so that the
opposite ends of the shaft 3 may be freely movable in the vertical direction on
the tops of the handle shaft 7 and the handle rotation shaft support 9 (Refer to
Fig. 5). Further, the top of the handle shaft 7 is provided with an actuating pin 8,
so that it can come into or out of the engagement with a hole 8b positioned in
the rear of the handle rotation shaft 3 through a through-hole 8a positioned at
that top, as shown in Figs. 2, 5 and 6, wherein the actuating pin is used to allow
the rotation or immobility of the handle rotation shaft 3. The handle rotation
shaft 3 which is pivotally mounted through bearings acts to allow the vertical
movement of the handle levers 6a and 6b in accordance with the movement of
the driver's hands.
The operating rod 11, which is positioned inwardly of the handle shaft 7,
the handle rotation shaft 3 and the handle rotation shaft support 9 contiguous
thereto, is fixed to the left or right side of the handle levers 6a and 6b, as shown
in Figs. 1 to 6, while the top part 11a maintains the free tilting of the handle
levers 6a and 6b through a pin hole 11b. Further, the lower part 11c of the
operating rod 11 is appropriately connected to the crank shaft 5 as a means to
transmitting the rotating force of the handle levers 6a and 6b to the pedal shaft
19.
8

The crank shaft 5 is connected to the operating rod 11 so as to be
movable up and down. As can be seen from Fig. 2, one end of the crank shaft 5
is connected to the flexible joint 15 provided in the rotation shaft 16 functioning
to transmit the rotating force of the handle levers 6a and 6b to the pedal shaft
19 through a cut-out groove 10b provided in the lower part of the handle shaft 7,
wherein the flexible joint 15 is positioned in the hollow cavity of a lower
supporting frame 4b which in turn is connected to the handle shaft supporting
member 10a of a bicycle. Further, the other end of the crank shaft 5 is
connected to the handle rotation shaft support 9 so as to allow for the crank
shaft 5 to turn freely. The crank shaft 5 is shaped approximately in the form of
U, wherein the projected part of the U form is connected to the bottom 11c of
the operating rod 11.
The above-described rotation shaft 16 is mounted in the inner cavity of
the lower supporting frame 4b, which is provided as a skeleton structure
between the handle shaft supporting member 10a of the handle shaft 7 and the
pedal shaft 19, as in ordinary bicycles, wherein one end of the rotation shaft 16
is connected to the flexible joint 15 moving smoothly corresponding to the
movement of the crank shaft 5 and the opposite end thereof is provided with the
driving gear 17.
Particularly as shown in the enlarged view of Fig. 12, the driving gear
17 is formed, on its inner circumference, with two toothed parts 17a at
diagonally opposite positions, that is, 180° spaced from each other.
Correspondingly, the bottom end of the rotating shaft 16 is mounted with two
rocking members 21 each having a toothed part 22, wherein the rocking
9

members 21 can elastically be expanded to or shrunk from the driving gear 17
on the base of the supporting point 21a by the springs 20 so as to engage with
or disengage from the gear 17.
A chain belt 13 is mounted around the two sprockets 14a and 14b as in
usual cases. In the arm and leg powered bicycle according to the invention, a
driven gear 18 is combined to the pedal shaft 19 for rotating the sprockets 14a
and 14b, wherein the driven gear 18 is so arranged as to be rotated by the
driving gear 17, as depicted in Fig. 2 and Figs. 9 to 11.
In order to speed up an arm and leg powered bicycle according to the
invention, as constructed as described in the above, the actuating pin 8 provided
on the top of the handle shaft 7 for the handle levers 6a and 6b is pulled upward,
as seen in Fig. 2, to permit the handle levers 6a and 6b, which have been
immovable together with the handle rotation shaft 3 due to the actuating pin 8,
to turn alternately about the handle rotation shaft 3, as shown in Figs. 7 and 8.
The operating rod 11 connected to the handle levers 6a and 6b are
caused to move up and down according to the movement as described above, so
that the crank shaft 5 for transmitting the rotating force of the handle levers 6a
and 6b to the pedal shaft 19 may be rotated around its horizontal ends by and
together with the rotating rod 11, as shown in Fig. 8.
Thus, the rotation of the crank shaft 5 is transferred to the rotation
shaft 16 through the flexible joint 15 connected to the crank shaft 5, so that the
rotation of the rotation shaft 16 causes, as concretely shown in Fig. 13b, the
rocking members 21 located at the bottom of the shaft 16 to advance elastically
toward the driving gear 17 on the base of the supporting point 21a under the
10

urging force of the springs 20, to thereby engage the toothed parts 22 with the
toothed parts 17a of the driving gear 17, resulting in the rotation of the latter,
whereby the driven gear 18 which is in engagement with the driving gear 17 and
is fastened around the pedal shaft 19 is caused to rotate in order finally to hand
over the torque of the handle levers 6a and 6b to the pedal shaft 19.
On the other hand, when the handle rotation shaft 3 is restrained by the
actuating pin 8, the operating means A for the vertical turning of the handle
levers 6a and 6b remains inactivated, as shown in Fig. 13a. In this case, when
the pedals 12 are rotated only by the feet, the driven gear 18 and the driving
gear 17 connected to the driven gear can be rotated, while the toothed parts 17a
of the driving gear 17 are little affected by the toothed parts 22 of the rocking
members 21 during this rotation due to the elastic property of the rocking
members 21 fixed to the immobile rotation shaft 16.
Thus, the inventive arm and leg powered bicycle having the above-
descried construction may be operated in such a manner that the left pedal 12a
is lowered for the half cycle of one turn of raising the left handle lever 6a and
the right pedal 12b is lowered for the subsequent half cycle of raising the right
handle lever 6b, wherein the leg power may simultaneously be added while the
corresponding pedal is forwardly lowered.
Accordingly, the arm and leg powered bicycle according to the invention
can be used so that the laborious raising or lowering of the handle levers 6a and
6b may cooperate synchronously with the pressing-down movement of the leg
pedals 12a and 12b, while maintaining the balance of the bicycle body. As is
evident, the inventive bicycle is characterized in that the power of the arms can
11

take part equally in driving the bicycle as compared to the conventional bicycle
depending exclusively on the power of the legs.
Now referring to Pigs. 14 to 18, the arm and leg powered bicycle shown
therein have the same construction as that shown in Figs. 1 to 13, except that
the operating rods 11, in the operating means A for turning the handle levers 6a
and 6b, are disposed at the two positions, that is, on the left and right sides of
the handle levers 6a and 6b, wherein the crank shaft 5' rotating synchronously
with the operating rods 11 is shaped in the form of doubled U or = to suit the
movement of the rods 11.
Particularly, as seen in the exploded perspective view of Fig. 15 and the
cross sectional view of Fig. 16, the two rods 11 are respectively connected to
the protrudent portions of the s shaped crank shaft 5'. When the handle levers
6a and 6b are caused to move up and down after removing the actuating pin 8 in
the inactive state as shown in Fig. 17, the operations take place in the same
way as in the foregoing first embodiment, as can be seen in Fig. 18.
Furthermore, in the arm and leg powered bicycle as shown in Figs. 19
to 23 representing the variant embodiment of the invention, the crank shaft 5",
on which a crank shaft gear 23 and a rotation shaft gear 24 as a bevel gears are
mounted, are installed.
As one operating rod 11 and the other operating rod 11 are
successively lowered and raised alternately, the crank gear 23 is rotated in one
direction to cause the gear 24 in engagement with this crank gear to rotate in
one constant direction, resulting in the rotation of the rotation shaft 16 through
the flexible joint 15 connected to the gear 24. Hereupon, the top parts 11a of the
12

operating rods 11 are constructed so as to move up and down more smoothly
with the help of ring members 25 disposed on the handle levers 6a and 6b, as
can be appreciated from Figs. 19 and 21, whereas the bottom parts 11c are
connected to the opposite ends of the crank shaft 5" having the gear 23. The
succeeding steps of operation are the same as in the foregoing embodiments.
The arm and leg powered bicycle according to the invention,
constructed as described above, are advantageous in that the handle levers are
moved up and down by the motion of the arms to transfer the rotating power to
the pedal shafts to thereby increase the stepping power by the feet for attaining
the doubled running speed of the bicycle and the exercise for the both arms can
be conducted simultaneously to benefit the health.
In addition, the arm and leg powered bicycle according to the invention
has the advantage that the rotating power of the handle levers can assuredly be
transferred to the pedal shaft in a simple way, while maintaining the balance of
the bicycle body, differently from the conventional front and rear wheel method,
and that rotating power produced by the hands cooperates synchronously with
the stepping power of the pedals in rotating the pedal shaft for the safe travel of
the bicycle.
