[0003] 2. Description of the Prior Art
[0004] Various kinds of typical exercisers have been developed for
simulating cycle exercising, and include a resistive device for
applying a resistive force against the foot pedals or the like.
Some of the exercisers may include a resistive device that may be
changed to different resistive forces. However, a complicated
configuration or a number of parts or elements are required for
applying the resistive force to the foot pedals or the like and for
adjusting to different resistive forces, and may not be easily
manufactured and assembled.
[0005] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional
exercisers.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
an exerciser including a tiltable seat support for simulating the
upward climbing and/or the down hill riding exercising.
[0007] The other objective of the present invention is to provide
an exerciser including an adjustable resistive device for applying
different resistive forces against the foot pedal devices or the
like.
[0008] The further objective of the present invention is to provide
an exerciser including an adjustable resistive device for applying
a greater resistive force against the foot pedal devices or the
like while simulating the upward climbing exercising, and/or for
applying a less resistive force against the foot pedal devices or
the like while simulating the down hill riding exercising.
[0009] In accordance with one aspect of the invention, there is

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] Referring to the drawings, and initially to FIGS. 1-3, an
exerciser in accordance with the present invention comprises a base
10 including a base frame 11 which includes a housing shaped
configuration having a pair of side walls 12 and having a pair of
ears 13 extended upward therefrom. A spindle 15 is laterally and
rotatably secured in the base frame 11, and an axle 16 is rotatably
secured in the ears 13. The base 10 further includes a pair of
columns 14 extended upward therefrom, such as located in front of
the base frame 11. A pair of foot pedals 3 are coupled to the
spindle 15 with a pair of cranks 31, for allowing the foot pedals 3
to be stepped or actuated to rotate the spindle 15 and to simulate
the typical cycling exercises.
[0024] A weight or a paddle wheel, or a flywheel 5 is rotatably
secured and supported on the columns 14 with a pivot pole 50. A
transmission device 4 includes a pulley or a sprocket 41 secured on
the spindle 15 and rotated in concert with the spindle 15, another
pulley or sprocket 42 secured on the pivot rod 50 and rotated in
concert with the pivot rod 50, and a coupling belt or a coupling
chain 43 is engaged over the pulleys or the sprockets 41, 42 for
coupling the spindle 15 to the flywheel 5, and for allowing the
flywheel 5 to be rotated and driven by the foot pedals 3 via the
cranks 31 and the spindle 15 and the transmission device 4.
[0025] A gearing transmission 2 is provided for coupling to the
spindle 15 and for allowing the spindle 15 to be transmitted or
coupled to the other members or devices. For example, the gearing
transmission 2 includes a pinion 21 secured on the spindle 15 and
rotated in concert with the spindle 15, a gear 22 rotatably secured
to the base frame 11 with a pivot rod 23 and engaged with the
pinion 21 so as to be rotated and driven by the spindle 15 via the
pinion 21, another pinion 24 secured on the pivot rod 23 and
rotated in concert with the gear 22, another gear 27 and a further
pinion 25 rotatably secured on the base frame 11 with a pivot rod
26, in which the gear 27 is engaged with the pinion 24, and another
gear 28 rotatably secured to the base frame 11 with a pivot shaft
29 and engaged with the pinion 25, such that the gear 28 may also
be rotated and driven by the spindle 15 via the gears 22, 27 and
the pinions 21, 25.
[0026] A seat support 6 includes a post 62 having a lower or a
bottom portion pivotally or rotatably secured on the base frame 11
of the base 10 with the pivot axle 16 and the ears 13, for allowing
the post 62 to be rotated forward or rearward relative to the base
10 about the pivot axle 16. Alternatively, the post 62 may also be
directly and pivotally or rotatably secured on the base 10 with the
pivot axle 16. A handle 63 is provided and secured on top of the
post 62 for supporting the upper portion of the users, a barrel 64
is secured to the post 62 with such as a shank 67 and disposed or
located rearward of the post 62 and preferably located above the
spindle 15 and the foot pedals 3. A seat cushion 65 is provided for
supporting the riders or the exercisers and has a seat tube 66
extended downward therefrom and engaged into and secured to the
barrel 64. The seat tube 66 is preferably adjustable up and down
relative to the barrel 64 according to the height of the users, for
example.
[0027] The post 62 includes an extension 68 extended therefrom,
such as extended rearward from the lower portion thereof. A lever
17 includes one end pivotally secured to the extension 68 of the
post 62 with a pivot pin 18, and the other end pivotally secured to
the gear 28 with a pivot pin 19 which is disengaged from or offset
from the shaft 29, such that the other end of the lever 17 or the
pivot pin 19 may be caused to rotate about the pivot shaft 29 by
the gear 28 and such that the the post 62 of the seat support 6 may
be forced and caused to rotate or to move forward and rearward in a
reciprocating action by the lever 17. The exerciser may be used to
simulate the upward climbing exercising when the post 62 is rotated
or moved rearward, and may be used to simulate the down hill riding
exercising when the post 62 is rotated or moved forward.
[0028] A resistive device, such as a resistive strap 51 is
partially engaged over the flywheel 5 and includes one end secured
to the base 10, and the other end secured to the post 62, such as
secured to the lower portion or the lower end of the post 62. In
operation, as shown in FIG. 4, when the post 62 is rotated or moved
forward relative to the base 10 and the flywheel 5 to simulate the
down hill riding exercising, the resistive strap 51 may be slightly
released from the flywheel 5 and may apply a less force against the
flywheel 5 similar to the down hill riding exercising of the
cycles. On the contrary, when the post 62 is rotated or moved
rearward relative to the base 10 and the flywheel 5 to simulate the
upward climbing exercising, the resistive strap 51 may further be
forced to move toward or against the flywheel 5 and may thus apply
a greater force against the flywheel 5 similar to the upward
climbing exercising of the cycles.
[0029] It is to be noted that the typical exercisers include a seat
post 62 that may not be tilted or moved relative to the supporting
base 10. The post 62 for supporting the seat cushion 65 may be
caused to rotate or to move forward and rearward relative to the
base 10 by the lever 17 and the gear transmission 2, in order to
simulate the down hill riding exercising and/or the upward climbing
exercising of the cycles. The additional provision and the
arrangement of the resistive strap 51 may apply a greater force
against the flywheel 5 when the post 62 is rotated or moved
rearward to simulate the upward climbing exercising, and may apply
a less force against the flywheel 5 when the post 62 is rotated or
moved rearward to simulate the down hill riding exercising.
[0030] Accordingly, the exerciser in accordance with the present
invention includes a tiltable seat support for simulating the
upward climbing and/or the down hill riding exercising, and
including an adjustable resistive device for applying different
resistive forces against the foot pedal devices or the like. The
adjustable resistive device may apply a greater resistive force
against the foot pedal devices or the like while simulating the
upward climbing exercising, and/or for applying a less resistive
force against the foot pedal devices or the like while simulating
the down hill riding exercising.
[0031] Although this invention has been described with a certain
degree of particularity, it is to be understood that the present
disclosure has been made by way of example only and that numerous
changes in the detailed construction and the combination and
arrangement of parts may be resorted to without departing from the
spirit and scope of the invention as hereinafter claimed.
