Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a lower muscle training
device, and more particularly to a lower muscle training device for
suitably training or exercising lower muscle groups of users.
[0003] 2. Description of the Prior Art
[0004] For training or exercising lower muscle groups of users,
various kinds of typical lower muscle training devices, such as
treadmills, stepping exercisers, or the like have been developed
for jogging or ladder climbing exercises.
[0005] However, the typical treadmills are primarily provided for
training the hearts and the lungs of the users, but may not be
provided for training or exercising the lower muscle groups of the
users.
[0006] Similarly, the typical stepping exercisers are also
primarily provided for training the hearts and the lungs of the
users, but also may not be provided for training or exercising the
lower muscle groups of the users.
[0007] Actually, while operating or exercising the typical
treadmills and the typical stepping exercisers, the legs of the
users are normally elevated by the muscle groups of the thigh
portions only, the foot portion may not be suitably moved or
exercised or rotated relative to the tibia, such that the lower
muscle groups of the users also may not be suitably trained or
exercised.
[0008] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional lower muscle
training devices.
SUMMARY OF THE INVENTION
[0009] The primary objective of the present invention is to provide
a lower muscle training device for suitably training or exercising
lower muscle groups of users.
[0010] In accordance with one aspect of the invention, there is
provided a lower muscle training device comprising a base, and a
foot support including an intermediate portion pivotally coupled to
the base with a pivot shaft, and including at least one foot pedal
for supporting users thereon. The foot pedal and the foot support
may be rotatable relative to the base about the pivot shaft by the
users, to train and exercise lower muscle groups of the users.
[0011] The base includes a front portion having a pad provided
thereon, for engaging with a front portion of the foot support, and
for cushioning the foot support. The base includes a protrusion
extended from the front portion thereof, to support the pad
thereon.
[0012] The base includes a rear portion having a stop provided
thereon, for engaging with a rear portion of the foot support, and
for cushioning the foot support. The base includes a socket
provided thereon, the stop includes an arm extended therefrom and
engaged into the socket of the base.
[0013] The arm of the stop includes a plurality of apertures formed
therein, and a latch engaged with the socket of the base, and
engaged with either of the apertures of the arm, to adjustably
secure the stop to the base, and to adjust an inclination or
tilting angle of the foot support relative to the base.
[0014] A resistive device may further be provided and coupled
between the foot support and the base, to apply a resistive force
against the foot support and to the users. It is preferable that
the resistive device may be selectively adjusted to different
resistive force for applying different resistive forces against the
foot support and the users.
[0015] The base includes a pair of beams each having an extension
extended outwardly and rearwardly therefrom, to increase a ground
contacting area and a stability of the base. The base may further
include a handle attached to the base, to support upper portions of
users.
[0016] Further objectives and advantages of the present invention
will become apparent from a careful reading of the detailed
description provided hereinbelow, with appropriate reference to the
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0023] Referring to the drawings, and initially to FIGS. 1-4, a
lower muscle training device in accordance with the present
invention comprises a base 10 including a pair of side beams 11
which are preferably parallel to each other, and a lateral beam 12
coupled between the side beams 11 at the front portion 13 of the
base 10. Each of the side beams 11 includes an extension 14
extended outwardly and rearwardly therefrom, to increase the ground
contacting area and the stability of the base 10.
[0024] The base 10 includes a bar 15 disposed or provided in the
middle portion 16 thereof, and straddled or secured between the
side beams 11, and includes one or more, such as two brackets 17
extended or provided on the bar 15, and includes a socket 18
attached or secured to the bar 15 and having an orifice 19 formed
therein. The base 10 further includes a protrusion 20 attached to
the front beam 12, and a soft or resilient or rubber pad 21
attached or disposed on the protrusion 20.
[0025] A foot support 30 includes a pair of poles 31, preferably
parallel to each other, and each having an intermediate portion 32
pivotally coupled to the base 10 with the brackets 17 and one or
more shafts 33. The foot support 30 further includes a rod 34
coupled between the poles 31 at the front portion 35 of the foot
support 30, and a coupler 36 attached to the rod 34. One or more,
such as two foot pedals 37 are secured on the poles 31 with
fasteners 38 respectively, and rotated in concert with the foot
support 30, for supporting users thereon (FIGS. 3-6).
[0026] In operation, as shown in FIGS. 4-6, the user may step on
the foot pedals 37, and may step or rotate the foot pedals 37
and/or the foot support 30 relative to the base 10 about the pivot
shafts 33, with the lower muscle groups of the users, in order to
train or exercise the lower muscle groups of the users. The pad 21
of the base 10 may be engaged with the front portion 35 of the foot
support 30 (FIG. 4), to cushion the foot support 30, and to reduce
noises that may be generated when the foot support 30 is hit or
impacted onto the base 10.
[0027] A resistive device 40, such as rubber strap or spring (not
shown), pneumatic or hydraulic cylinder or actuator 40, or the
like, may further be provided and coupled between the foot support
30 and the base 10, to apply a resistive force against the foot
support 30, and thus to apply a resistive force against the feet of
the users, in order to further train or exercise the lower muscle
groups of the users.
[0028] For example, the resistive device 40 includes one end 41
pivotally coupled to the coupler 36 of the foot support 30, and
another end 42 pivotally coupled to another coupler 43 of the base
10, in order to apply the resistive force against the foot support
30 and the users. It is preferable that the resistive device 40
includes an adjustable device (not shown) to selectively adjust the
resistive force thereof applied against the foot support 30 and the
users.
[0029] A stop 50 may further be provided and attached to the base
10, to engage with the rear portion 39 of the foot support 30
(FIGS. 5, 6), and to cushion the foot support 30, and to reduce
noises that may be generated when the foot support 30 is hit or
impacted onto the base 10. The stop 50 includes an arm 51 extended
therefrom and slidably engaged into the socket 18 of the base
10.
[0030] The arm 51 includes one or more apertures 52 (FIG. 1) formed
therein, and adjustably aligned with the orifice 19 of the socket
18, to selectively receive or engage with a fastener or a latch 53
which may be engaged through the orifice 19 of the socket 18 and
either of the apertures 52 of the arm 51, to adjustably secure the
stop 50 to the base 10, and to adjust the relative position between
the foot support 30 and the base 10, and thus to adjust the
inclination or the tilting angle of the foot support 30 relative to
the base 10.
[0031] When the stop 50 of the base 10 is adjusted relative to the
foot support 30 to different position, in order to adjust to
different inclination or tilting angle between the foot support 30
and the base 10, the resistive force of the resistive device 40
applied against the foot support 30 and the users may also be
adjusted, to allow the users to spend different energy to operate
or to exercise the lower muscle training device.
[0032] In operation, as shown in FIGS. 4-6, the user may step on or
rotate the foot pedals 37 and/or the foot support 30 relative to
the base 10 about the pivot shafts 33, with the lower muscle groups
of the users, in order to train or exercise the lower muscle groups
of the users. The front portion 35 of the foot support 30 may be
engaged with the pad 21 of the base 10, and the rear portion 39 of
the foot support 30 may be engaged with the stop 50 of the base 10,
to cushion the foot support 30, and to reduce noises that may be
generated when the foot support 30 is hit or impacted onto the base
10.
[0033] As shown in FIG. 7, a handle 23 may be selectively or
optionally attached to the base 10, to support the upper portions
of the users, and to allow new beginners or children or elders to
easily and safely operate or exercise the lower muscle training
device without falling down from the lower muscle training
device.
[0034] Accordingly, the lower muscle training device in accordance
with the present invention may be used for suitably and safely
training or exercising lower muscle groups of users.
[0035] 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.
