DETAILED DESCRIPTION OF THE INVENTION
[0017] Referring to the drawings and initially to FIGS. 1-3, a
stepping foot trainer in accordance with the preferred embodiment
of the present invention comprises a base frame 10, a pivot frame
20 pivotally mounted on the base frame 10, two spaced pedals 40
mounted on the pivot frame 20 to pivot with the pivot frame 20
simultaneously, a hydraulic damping mechanism 30 mounted between
the base frame 10 and the pivot frame 20 to provide a damping
effect to the pivot frame 20, and an upright handlebar 50 mounted
on the base frame 10 to facilitate a user holding the handlebar
50.
[0018] The base frame 10 has a substantially U-shaped
configuration. The base frame 10 has a front section having a side
provided with a support tube 16.
[0019] The pivot frame 20 has a substantially U-shaped
configuration. The pivot frame 20 has a rear section formed with
two transverse pivot holes 23. The pivot frame 20 has a plurality
of upright bolt holes 21 for mounting the two pedals 40 by a
plurality of locking bolts 22. The bolt holes 21 and the pivot
holes 23 of the pivot frame 20 are formed in two side bars of the
pivot frame 20.
[0020] The stepping foot trainer further comprises a transverse
support seat 11 mounted on a rear section of the base frame 10, two
spaced pivot seats 12 mounted on the support seat 11 for pivoting
the pivot frame 20, two pivot bolts 25 each extended through a
respective one of the pivot seats 12 and a respective one of the
pivot holes 23 of the pivot frame 20 so that the rear section of
the pivot frame 20 is pivotally mounted on the pivot seats 12, a
transverse limit pin 14 mounted on a first one of the pivot seats
12, an upright catch rod 29 mounted on a bottom of the rear section
of the pivot frame 20 and movable to abut the limit pin 14 to
prevent an excessive movement of the pivot frame 20, a magnet 122
mounted on a side of the first one of the pivot seats 12, a
magnetic detection member 28 mounted on the bottom of the rear
section of the pivot frame 20 and movable to pass by the magnet.
122 to count a number of pivot of the pivot frame 20, a first
support bracket 15 mounted on the support seat 11, a second support
bracket 26 mounted on a front section of the pivot frame 20, and a
bumper 27 mounted on a bottom of the front section of the pivot
frame 20 and movable to abut the front section of the base frame 10
to provide a buffering effect to the pivot frame 20.
[0021] Each of the pivot holes 23 of the pivot frame 20 is provided
with two spaced bushings 24 mounted on the respective pivot bolt
25. The first one of the pivot seats 12 is formed with a plurality
of transversely arranged adjusting holes 13, and the limit pin 14
is adjustably mounted in either one of the adjusting holes 13 of
the pivot seats 12 to adjust a backward inclined angle of the pivot
frame 20. The support seat 11 straddles two side rods of the base
frame 10. The support seat 11 is formed with a substantially
T-shaped recess 18 located between the pivot seats 12 to receive
the first support bracket 15. The side of the first one of the
pivot seats 12 is formed with an outwardly extending ear 121 for
mounting the magnet 122. The second support bracket 26 is provided
with a mounting plate 261 for mounting an electronic indicator 60
which is electrically connected to the magnetic detection member 28
to indicate the number of pivot of the pivot frame 20.
[0022] The hydraulic damping mechanism 30 includes a hydraulic
cylinder 31 having a distal end pivotally mounted on the first
support bracket 15, and a movable rod 32 retractably mounted in the
hydraulic cylinder 31 and having a distal end pivotally mounted on
the second support bracket 26.
[0023] The handlebar 50 is detachably mounted on the base frame 10
and includes an outer tube 52 having a lower end detachably mounted
on the support tube 16 of the base frame 10 by a fastening bolt 17,
and an inner tube 51 retractably mounted in the outer tube 52 and
fastened by a clamping member 53.
[0024] In operation, referring to FIGS. 1-4, a user's two feet are
placed onto the pedals 40 and exert a force on the pedals 40 to
overcome the damping force of the hydraulic damping mechanism 30 so
as to drive the pivot frame 20 to pivot relative to the base frame
10 so that the pivot frame 20 is pivoted forward and downward as
shown in FIG. 3, or pivoted backward and downward as shown in FIG.
4. Thus, the user's two feet stepping the pedals 40 have to exert a
force to overcome the damping force of the hydraulic damping
mechanism 30 so as to exercise the muscle of the user's two feet
and legs, thereby achieving the exercising effect.
[0025] When the pivot frame 20 is pivoted forward and downward as
shown in FIG. 3, the bumper 27 is movable to abut the front section
of the base frame 10 to provide a buffering effect to the pivot
frame 20, and when the pivot frame 20 is pivoted backward and
downward as shown in FIG. 4, the catch rod 29 is movable to abut
the limit pin 14 to prevent an excessive movement of the pivot
frame 20.
[0026] As shown in FIG. 1, the upright handlebar 50 can be held by
the user's one hand to provide a balance effect to the user when
stepping the pedals 40.
[0027] As shown in FIGS. 4 and 5, the limit pin 14 is adjustably
mounted in either one of the adjusting holes 13 of the pivot seats
12 to adjust the backward inclined angle of the pivot frame 20.
[0028] Accordingly, the user's two feet step on the pedals 40 to
move the pedals 40 simultaneously and to exert a force to overcome
the damping force ol the hydraulic damping mechanism 30 so as to
exercise the muscle of the user's two feet and legs, thereby
achieving the exercising effect. In addition, when the pivot frame
20 is pivoted forward and downward, the bumper 27 is movable to
abut the front section of the base frame 10 to provide a buffering
effect to the pivot frame 20, and when the pivot frame 20 is
pivoted backward and downward, the catch rod 29 is movable to abut
the limit pin 14 to prevent an excessive movement of the pivot
frame 20, thereby providing a safety effect to the user when
stepping the pedals 40. Further, the upright handlebar 50 can be
held by the user's one hand to provide a balance effect to the user
when stepping the pedals 40. Further, the handlebar 50 is
detachably mounted on the base frame 10, thereby facilitating
packaging, storage and transportation of the stepping foot
trainer.
[0029] Although the invention has been explained in relation to its
preferred embodiment(s) as mentioned above, it is to be understood
that many other possible modifications and variations can be made
without departing from the scope of the present invention. It is,
therefore, contemplated that the appended claim or claims will
cover such modifications and variations that fall within the true
scope of the invention.
