DETAILED DESCRIPTION OF THE INVENTION
[0018] With reference to FIGS. 1-4, a pedal exerciser according to
the present invention includes a base 1, a pedaling device 2, an
adjusting mechanism 3, and an auxiliary positioning mechanism 4.
The base 1 includes a mounting seat 11 at a front end thereof and a
seat 12 at a rear end thereof. A user can sit or lie on the seat 12
while using the pedal exerciser. The mounting seat 11 includes two
coupling boards 13, with a compartment 131 defined between the
coupling boards 13. Each coupling board 13 includes a top end
having an axle coupling portion 132 with a notch 133. At least one
of the coupling boards 13 further includes a plurality of guiding
slots 134 and a plurality of pegs 135. A control lever 14 is
pivotably mounted to the base 1 and attached to an end of a cable
141.
[0019] The pedaling device 2 is adapted to be rotated by the legs
or hands or the user. The pedaling device 2 includes a column 21 on
a lower portion thereof. The column 21 includes mounting holes 22.
The column 21 further includes an axle portion 23 engaged with the

the axle coupling portions 132. The axle portion 23 further
includes a tightening knob 232 and a tightening plate 233 for
clamping and tightening one of the coupling boards 13.
[0020] The adjusting mechanism 3 is received in the compartment 131
of the base 1 and includes a toothed plate 31 and a transmission
device 32. The toothed plate 31 includes mounting holes 311 at an
upper end thereof. Fasteners are extended through the mounting
holes 311 and the mounting holes 22 of the column 21, fixing the
toothed plate 31 to the column 21. The toothed plate 31 further
includes an arcuate toothed portion 312 at a lower end thereof. The
transmission device 32 includes a motor 321, a reduction gear train
322, and a transmission gear 33. The motor 321 is connected to the
reduction gear train 322 and controlled by a controller. The
transmission gear 33 is coupled to an output shaft 3221 of the
reduction gear train 322 and meshes with the arcuate toothed
portion 312 of the toothed plate 31. The motor 321 is operable by
the controller to drive the reduction gear train 322, the
transmission gear 33, and the toothed plate 31. The pedaling device
2 is pivotably connected to the mounting seat 11, with the axle
portion 23 defining a pivot axis of the pedaling device 2 to allow
adjustment of an angle of the pedaling device 2 relative to the
base 1, providing convenient adjustment.
[0021] The auxiliary positioning mechanism 4 is mounted in the
compartment 131 of the base 1 and includes two toothed blocks 41, a
follower device 42, and three elastic elements 45. Two guiding pins
412 are provided for each toothed block 41, with each guiding pin
412 extending through one of the guiding slots 134. Each guiding
slot 134 extends in a direction transverse to the arcuate toothed
portion 312 such that each toothed block 41 can be moved to engage
with or disengage from the toothed plate 31 through movement of the
guiding pins 412 in the guiding slots 134.
[0022] The follower device 42 is connected to the cable 141 and the
toothed blocks 41. The control lever 14 can be operated to control
the toothed blocks 41 to engage with or disengage from the toothed
plate 31 through transmission by the cable 141. The follower device
42 includes a connection plate 43 and an actuation plate 44. The
connection plate 43 includes guiding slots 431 and 432. A bolt 413
is slideably extended through each guiding slot 431 and fixed to
one of the toothed blocks 41. Another bolt 414 is slideably
extended through the guiding slot 432 of the connection plate 43
and fixed to one of the coupling boards 13. The connection plate 43
can move upward and downward relative to the coupling boards 13,
moving the toothed blocks 41 upward to engage with the toothed
plate 31 or moving the toothed blocks 41 downward to disengage from
the toothed plate 31. The connection plate 43 further includes a
guiding peg 433 and attachment holes 434. The actuation plate 44 is
connected to the other end of the cable 141 and includes an end
pivotably connected to one of the coupling boards 13. The actuation
plate 43 includes a guiding groove 441 in which the guiding peg 433
is slideably received. The actuation plate 44 further includes an
attachment hole 442. The springs 45 are attached to the pegs 135 of
the coupling board 13 of the base 1 and the attachment holes 434
and 442 of the connection plate 43 and the actuation plate 44.
[0023] With reference to FIG. 4, before operation of the control
lever 14, the connection plate 43 and the actuation plate 44 are
biased by the elastic elements 45 to a locked position. The toothed
blocks 41 mesh with the toothed plate 31 to assist in positioning
of the pedaling device 2 in a desired angular position.
[0024] With reference to FIG. 5, when adjustment of the angle of
the pedaling device 2 relative to the base 1 is required, the
control lever 14 is operated to move the actuation plate 44 via the
cable 141. A peripheral wall of the guiding slot 441 presses
against the guiding peg 433 to move the connection plate 43
downward. Furthermore, a peripheral wall of each guiding slot 431
presses against one of the bolts 413, disengaging the toothed
blocks 41 from the toothed plate 31.
[0025] With reference to FIGS. 1, 2, and 6, the motor 321 is
activated to adjust the angle (or angular position) of the pedaling
device 2 relative to the base 1 through transmission of the toothed
plate 31. With reference to FIG. 7, after adjustment, the control
lever 14 is moved in a reverse direction to return the connection
plate 43 and the actuation plate 44 to the locked position under
the action of the elastic elements 45. The toothed blocks 41
reengage with the toothed plate 31 to fix the angular position of
the pedaling device 2. The tightening knob 232 is rotated to
tightly clamp the coupling board 13 with the tightening plate 233,
providing a reliable positioning effect.
[0026] In view of the foregoing, the adjusting mechanism 3 provides
convenient adjustment of angle of the pedaling device 2 while
providing a reliable positioning effect. If desired, the pedal
exerciser does not have to include the auxiliary positioning
mechanism 4. The transmission gear 33 meshes with the toothed plate
31 to provide a positioning effect when the motor 321 is not
activated. The number of the toothed blocks 41, the guiding slots
134, the attachment holes 434 and 442, and the elastic elements 45
can be varied according to need.
[0027] Although specific embodiments have been illustrated and
described, numerous modifications and variations are still possible
without departing from the essence of the invention. The scope of
the invention is limited by the accompanying claims.
