Standing-pedaling Bike
Bac gerund of the Invention:
This invention relates to a bike, and particularly to a standing-pedaling
bike.
05 ~ Descriht6on of the Prior Art:
Most of the conventional bikes are usually used as transportation equipment by
riding
thereon.
In a conventional two-wheel transportation equipment, the spindle of the rear
wheel of
a bike is in an eccentric shape; when a user rides to go forwards, the rear
end of the bike
would swing, i.e., being similar to riding on a horse.
In a conventional two-wheel transportation equipment, the frame between two
wheels
is a flat plate, being close to the ground surface; the user can put one foot
on the flat plate,
while the other foot can put on the ground as a driving means so as to provide
an exercise
and riding function.
Summay of the Invention:
The prime object of the present invention is to provide a standing-pedaling
bike, in
which the pedal shafts on two cranks on both sides of the bike frame are
mounted with two
rollers respectively; the rear end of the fork frame is furnished with fixed
shafts to be
mounted with shaft sleeves of the pedal plates respectively so as to form into
two swinging
shafts of the pedal plates; the pedal plates each have a wide surface to
facilitate pedaling;
when the cranks turn, the pedal plates will swing up and down so as to let a
user ride
thereon.
Another object of the present invention is to provide a standing pedaling
bike, in which
both sides of the fork frame are furnished with two fixed shafts for
supporting the pedal
plates in pivotal connection so as to provide a fulcrum upon the pedal plates
swinging; the
- 1 -

other ends of the two pedal plates are in contact with the pedal shafts on the
outer ends of
the cranks respectively. When the pedal plates are pedaled, the pedal shafts
will move
circularly so as to have the pedal plates each had a swinging end; when a user
stands and
rides on the bike, the bike will move forwards.
05 Still another object of the present invention is to provide a standing-
pedaling bike, in
which two pedal plates are mounted between the two fixed shafts on both sides
of the fork
frame and the two pedal shafts respectively; two ends of the pedal plates are
furnished with
two shaft sleeves to be mounted on two fixed shafts on both sides of the fork
frame, and the
fixed shafts are used as rotary fulcrum, while the other ends of every pedal
plate has a guide
channel to be mounted on a roller mounted on a pedal shaft on outer end of a
crank; when
the pedal plate is pedaled to swing up and down, the guide channel under the
pedal plate
will guide the roller on the pedal shaft to slide and move in the guide
channel.
A further object of the present invention is to provide a standing-pedaling
bike, in which
two pedal plates are mounted between two fixed shafts on both sides of the
fork frame and
the pedal shafts respectively; two ends of the pedal plates have shaft sleeves
respectively to
be mounted on two fixed shafts on both sides of the fork frame; the fixed
shafts are used as
~ rotary fulcrums thereof, while the other end of each pedal plate has an
elongate guide
channel underneath for receiving a roller; when the pedal plate is pedaled to
move circularly,
the elongate guide channel will guide the roller on the pedal shaft to move.
A still further object of the present invention is to provide a standing-
pedaling bike, in
which two pedal plates are mounted between two fixed shafts on both sides of
the fork frame
and the pedal shafts; two ends of the two pedal plates are mounted on two
pedal shafts
respectively, while the other end of each pedal plate is furnished with an
elongate guide
channel underneath; the two elongate guide channels are used for receiving two
fixed shafts
on both sides of the fork frame. When the pedal plates are pedaled to move
circularly, one
- 2 -

end of each pedal plate will move circularly, while the other end having an
elongate guide
channel will cause the pedal plate to slide and move along the fixed shaft on
both sides of
the fork frame.
Yet another object of the present invention is to provide a standing-pedaling
bike, in
05 which two pedal plates are mounted between the two fixed shafts on both
sides of the fork
frame and the pedal shafts; one end each pedal plate is mounted on a pedal
shaft, while the
other end is connected with a swinging link; the other end of the swinging
link is connected
with the fork frame. When the pedal plate is pedaled to move circularly, one
end of the pedal
plate will move circularly, while the swinging link on the other end will
swing upon the pedal
plate moving.

This invention relates to a standing-pedaling bike; as shown in Figs. 1 to 4,
a spindle
- 3 -
CA 02363219 2001-11-20
13 is furnished between the bike frame 11 and the fork frame 12; both ends of
the spindle 13
are mounted with cranks 15 and 16 respectively. The tail ends of the cranks 15
and 16 are
mounted with two pedal shafts 17 and 18 respectively. The crank 15 on one side
of the
spindle 13 is mounted with a gear wheel 14, on which a chain 35 is mounted for
coupling
05 with a ratchet wheel 38. When the pedal shafts 17 and 18 are pedaled by
feet, the chain 35
will drive the ratchet wheel 38 to rotate, and the rear wheel 36 will turn to
move forwards.
The assembly including cranks 15 and 16 and the pedal shafts 17 and 18 on both
sides
of the spindle 13 on the bike frame 11 can provide a user with the same parts
for pedaling
away by standing on the bike; however, the pedal shafts 17 and 18 on the
cranks 15 and 16
are mounted with two rollers 19 and 20 respectively, which have a given
diameter and width.
The outer ends of the pedal shafts 17 and 18 are mounted with washers and two
nuts 21
and 22 respectively to prevent the rollers 19 and 20 from separating from the
pedal shafts 17
and 18 unintentionally.
The rollers 19 and 20 of the pedal shafts 17 and 18 on the outer ends of the
cranks 15
and 16 are mounted with two pedal plates 23 and 24 respectively. Both sides of
the fork
frame 12 are mounted, by means of welding, with two fixed shafts 25 and 26
respectively to
facilitate the shaft holes 29 and 30 of the shaft sleeves 27 and 28 to mount
on ends of the
pedal plates 23 and 24 respectively. The outer ends of the fixed shafts 25 and
26 are
furnished with threads respectively; after the pedal plates 23 and 24 are
mounted with two
shaft sleeves 27 and 28 respectively, washers and two nuts 31 and 32 are fixed
in place so
as to have one end of the two pedal plates 23 and 24 mounted on the fixed
shafts 25 and 26
on both sides of the fork frame, and to prevent the pedal plates 23 and 24
from separation.
The shaft sleeves 27 and 28 on ends of the pedal plates 23 and 24 are to be
mounted
on the fixed shafts 25 and 26 on both sides of the fork frame 12 respectively;
then, washers
and nuts 31 and 32 are mounted thereto respectively so as to prevent the pedal
plates 23
- 4 -
CA 02363219 2001-11-20
and 24 from separating from the fixed shafts 25 and 26 of the fork frame 12;
the shaft
sleeves 27 and 28 on ends of the pedal plates 23 and 24 have two shaft holes
29 and 30
respectively to be mounted on the fixed shafts 25 and 26 so as to have a
pivotal connection
between them. The fixed shafts 25 and 26 form the fulcrums of the two pedal
plates 23 and
05 24 respectively upon swinging so as to have the rollers 19 and 20 on the
outer ends of the
cranks 15 and
15 turned upon pedaling, i.e., the pedal plates can swing up and down. In that
case, one end
of every the pedal plate 23 or 24 on the roller 19 or 20 can turn around the
fixed shaft 25 or
26 of the fork frame 12. When a user's foot pedals on the pedal plate 23 and
24, a pressure
will be applied to a roller19 or 20 on the crank 15 or 16 to cause a pedal
shaft 17 and 18 to
move circularly. The length of every roller 19 or 20 is designed to fit the
width of the guide
channel 33 or 34 beneath the pedal plate 23 or 24; the guide channel can
provide a guide
and shift function, and also can prevent the pedal plate 23 or 24 from
shifting laterally. After
the rollers 19 and 20 of the pedal shafts 17 and 18 are assembled together
with the guide
channels 33 and 34 and the pedal plates 23 and 24 respectively, they are in
rolling contact
with each other so as to minimize the friction resistance between the pedal
plates 23 and 24
and the rollers 19 and 20.
The pedal plates 23 and 24 mounted on the rollers 19 and 20 are flat plates
having a
given width; the pedal plates are designed to carry a user's feet and the
surface of the pedal
plates is furnished with sliding-proof threads, or glued with a sliding-proof
piece so as to
provide a given friction upon pedaling.
As soon as a user's one foot is put on a pedal plate at a higher position, a
given weight
will be applied to the pedal plate; in that case, the roller under the pedal
plate will roll along
the guide channel to cause the pedal shaft to move forwards circularly so as
to drive the
gear wheel, the chain 35 and the rear wheel 36 to move forwards.

The pedal plates 23 and 24 are mounted on both sides of the fork frame 12 and
on the
cranks 15 and 16 respectively.by means of shaft sleeves 27 and 28 furnished on
ends of the
pedal plates respectively as shown in Figs. 1 to 4; the shaft sleeves have
shaft holes 29 and
30 respectively to facilitate the shaft sleeves to mount on the fixed shafts
25 and 26 on both
05 sides of the fork frame 12 so as to enable the pedal plates 23 and 24 to
swing up and down;
then, the guide channels 33 and 34 in close contact with the rollers 19 and 20
underneath
enable the cranks 15 and 16 to move circularly upon pedaling.
Fig. 5 shows the second embodiment of the present invention in which both
sides of
the fork frame 12 same as the aforesaid embodiment are furnished with two
fixed shafts 25
and 26 respectively; the shaft sleeves 27 and 28 on ends of the two pedal
plates 23 and 24
are to be mounted on the fixed shafts 25 and 26 respectively so as to enable
the pedal
plates 23 and 24 to swing. The pedal shafts 17 and 18 on outer ends of the
cranks 15 and
16 are mounted with rollers 19 and 20 same as the aforesaid embodiment;
however, the
contact surface between the pedal shafts 17 and 18 and the rollers 19 and 20
are furnished
with two guide plates 39 respectively; the elongate sliding channels 37 formed
with the guide
plate 39 are used for receiving the rollers 19 and 20 respectively so as to
enable the rollers
19 and 20 to move circularly; the elongate sliding channels 37 and the rollers
19 and 20 are
formed into coupling assembly respectively so as to limit the pedal plates 23
and 24 from
swinging upwards too high.
Fig. 6 shows the third embodiment of the present invention, in which the
bottom sides
of the pedal plates 23 and 24 are furnished with shaft sleeves 40 and 41
respectively, which
are mounted on the pedal shafts 17 and 18 on the outer ends of the cranks 15
and 16. The
other ends of the pedal plates 23 and 24 are furnished with two elongate
sliding channels 45
respectively to be mounted on two rollers 42 and 43 of two fixed shafts 25 and
26 on both
sides of the fork frame 12; then, washers and nuts 31 and 32 are mounted to
the fixed shafts
- 6 -

25 and 26 respectively to keep the pedal plates in place. When a user's feet
pedal on the
pedal plates 23 and 24, the shaft sleeves 40 and 41 under the pedal plates 23
and 24 will
drive the cranks 15 and 16 to move circular by under the limit and guide of
the elongate
sliding channels on ends of the pedal plates 23 and 24 and the rollers 42 and
43.
05 Fig. 7 shows the fourth embodiment of the present invention, in which the
bottom
sides of the pedal plates 23 and 24 are furnished with two shaft sleeves 40
and 41
respectively, which are mounted on the pedal shafts 17 and 18 on the outer
ends of the
cranks 15 and 16 respectively. The other ends of the pedal plates 23 and 24
are furnished
with iwo shaft sleeves 27 and 28 to be mounted on two fixed shafts 25~ and 26
on the lower
side of two swinging links 47 and 48 respectively, and such shaft sleeves are
fastened in
place by means of washers and nuts respectively; the other ends of the
swinging links 47
and 48 are pivotally connected with the prop frames 46 respectively. The
swinging links 47
and 48 are pivotally mounted on the center of the prop frames respectively.
When the pedal
plates 23 and 24are pedaled, the pedal shafts 17 and 18 of the cranks 15 and
16 will be
driven to move circularly; simultaneously, the fixed shafts 25 and 26 on the
other ends of the
pedal plates 23 and 24 will pull the swinging links 47 and 48 to swing without
affecting the
circular move of the pedal shafts 17 and 18; a person can stand on the pedal
plates 23 and
24 to pedal and move forwards.
The aforesaid embodiments of the present invention have disclosed the features
and
structures completely. The fixed shafts on the rear part of the fork frame are
used as prop
and rotary shafts; after the pedal plates are pedaled, the pedal shafts will
move circularly to
drive the gear wheel, the chain and the rear wheel to move forwards so as to
provide a fun
of exercise; it is apparent that the present invention has provided obvious
improvement
which is never anticipated and achieved by any person in the field, and the
structure of the
present invention is deemed unique.
