Description
BACKGROUND OF THE INVENTION
[0001] (a) Field of the Invention
[0002] The present invention is related to a fitness equipment, and
more particularly, to an improved structure of a treadmill that
simulates treading motion for its user to achieve treading and
twisting exercise purposes at the same time.
[0003] (b) Description of the Prior Art
[0004] People today often use excuses such as poor weather, or
tight schedule to lead a life with little or even no sports at all,
and recognize the importance of keeping a proper amount of sports
when they find their immunity is deteriorating and symptoms of
chronic diseases. Even so, they are reluctant to spare certain time
each day to work out at a specific site or purchase fitness
equipment to work out in leisure time.
[0005] To cope with the particular needs of the modern people who
needs proper amount of workout while leading a busy life, fitness
equipment simulating its best the outdoor workout patterns and
allowing easy operation have been developed such as the one
illustrated in FIG. 1. The prior art relates to a compact treadmill
generally available in the market is essentially comprised of two
pedals 21 that allow vertical movement axially pivoted to a base 10
and a hydraulic cylinder 22 or a parallel connection rod member is
coupled to where between both pedals 21 and the base 10. The user
alternatively treads on both pedals 21 for a tread unit 20 to
reciprocal move in simulation of walking movement to achieve the
purpose of staying fit.
[0006] However, the treadmill of the prior art gets too monotonous
to encourage continuous use for its user. As a result, the fitness
equipment winds up in storage room for good.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0017] Referring to FIGS. 2(A), 2(B), 3, and 4, a preferred
embodiment of the present invention includes a mechanical
construction with a base 10 as the primary member, a treading unit
20, a turning member 30, and a transmission unit. The treading unit
20 for being subject to the force applied by both feet of the user
to proceed vertical motion pattern by simulating the stepping and
pacing movement up and down. Meanwhile, a rhythmic rotation device
is comprised of the treading unit 20, the turning member 30 and the
transmission unit 40. As the rhythmic rotation device is operating
and both feet of the user are stepping onto the treading unit 20 to
have vertical motions, the turning member 30 and the treading unit
20 are engaging in reciprocal rotation for the user to achieve
fitness results of twisting and treading at the same time.
[0018] Within the rhythmic rotation device, the treading unit 20
serves as an active mechanism to provide vertical motions; the
turning member 30 supports the treading unit 20 to become a passive
member; and the transmission unit 40 converts kinetics from the
treading unit 20 into that of a connection mechanism to drive the
transmission 40 to engage in lateral rotation to secure the
connected motions between the treading unit 20 and the turning
member 30.
[0019] In the preferred embodiment, the turning member 30 is
comprised of a turning table axially pivoted to the base 10. A pair
of parallel connection rods 23 to relatively engage in vertical
oscillation is axially pivoted to the peripheral of the axis of the
turning member 30. Two pedals 21 are respectively provided at the
distal ends of both parallel connection rods 23. Through the
connection of the pair of the connection rods 23, the motion from
the treading unit 20 when subject to the force applied by both feet
of the user on both pedals 21 produces the motive results of
alternatively vertical motion between two pedals 21 as illustrated
in FIG. 6.
[0020] In practice, the transmission unit 40 as illustrated in
FIGS. 2(A), 2(B), 3, 4, and 5, is comprised of a segment gear 41
fixed to the axis at the middle of the pair of parallel connection
rods 23, and a conical gear 42 fixed to the base 10. Wherein, the
center of the conical gear 42 is where a vertical shaft 31 of the
turning member 30 is provided. Both of the conical gear 42 and the
segment gear 41 are engaged to each other. When both parallel
connection rods 23 relatively oscillate up and down, the segment
gear 41 laterally swings along with the axis and is forced to
reciprocally roll along the surface of the teeth of the conical
gear 42 since the conical gear 42 is dead thus to drive the turning
member 30 and the treading unit 20 to engage in reciprocal
movement.
[0021] As illustrated in FIGS. 3 and 4, an upper lid to cover the
mobile range at the center of both parallel connection rods 23 is
fixed to the base 10 to improve the user safety. A damper 50 is
disposed at where between the turning member 30 and the base 10. A
press plate 51 to produce packing force against the turning member
30 is provided to the damper 50 on the side of the base 10. The
press plate 51 at its end in relation to the base 10 is screwed to
the base 10 by means of a bolt 52; and the end of the press plate
51 extends into a guide slot 32 of the turning member 30 by means
of a pin 53 to provide positioning function depending on the
displacement of the turning member 30. Wherein, a plate 33 extends
from the turning member 30 towards the press plate 51. The packing
by the press plate 51 and the base 10 against the extension plate
33 is adjusted by the torque of the bolt 52 to achieve the purpose
of adjusting the amount of the force applied to the S twisting
treadmill. One or a plurality of friction pad is further provided
at where between the press plate 51 and the extension plate 33 as
well as the extension plate 33 and the base 10 to improve the
friction efficacy of the damper 50.
[0022] Furthermore, as illustrate din FIG. 8, the transmission unit
40 is comprised of a chain 43 fixed to the turning member 30 and a
chain gear 44 fixed to the base 10; or alternatively as illustrated
in FIG. 9 the transmission unit 40 is comprised of a steel cable 45
fixed to the turning member 30 and a pulley 46 fixed to the base.
Wherein, A stud 451 and a recess 461 that coupled to each other are
respectively disposed to the steel care 45 and the surface of the
pulley 40 to achieve the same transmission purpose of driving the
turning member 30 to exercise reciprocal rotation.
[0023] The prevent invention provides an improvement structure of a
twisting treadmill, and the application for a utility patent is
duly filed accordingly. However, it is to be noted that that the
preferred embodiments disclosed in the specification and the
accompanying drawings are not limiting the present invention; and
that any construction, installation, or characteristics that is
same or similar to that of the present invention should fall within
the scope of the purposes and claims of the present invention.
