Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a mini stepper, and more
particularly to a mini stepper that is supported on the ground
rigidly and stably, thereby facilitating the user operating the
mini stepper.
[0003] 2. Description of the Related Art
[0004] A conventional mini stepper in accordance with the prior art
shown in FIG. 6 comprises a substantially H-shaped support frame 30
having two support rods 32 each supported by two stands 36 and a
crossbar 34 mounted between the two support rods 32, a shaft tube
40 having a first end secured on the support frame 30, two pedals
42 each having a first end pivotally mounted on a second end of the
shaft tube 40, and two hydraulic mechanisms 44 each having a first
end pivotally mounted on the support frame 30 and a second end
pivotally mounted on a second end of a respective one of the two
pedals 42.
[0005] However, the crossbar 34 is combined with the two support
rods 32 by soldering, thereby decreasing the aesthetic quality of
the mini stepper, and thereby increasing the procedure of
fabrication. In addition, the mini stepper is supported by the four
stands 36 only, so that the mini stepper has a smaller contact area
with the ground. Thus, the mini stepper is not supported on the
ground rigidly and stably, thereby causing inconvenience to the
user when operating the mini stepper. Further, the mini stepper has
a smaller contact area with the ground, so that the weight of the
user is entirely concentrated on the mini stepper, thereby
decreasing the lifetime of the mini stepper.
SUMMARY OF THE INVENTION
[0006] The primary objective of the present invention is to provide
a mini stepper, wherein the extension of the support rack is
extended outward from the mounting portion of the support rack in
an oblique downward manner, and each of the two stands of the
support member is extended outward from the mounting portion of the
support member in an oblique downward manner, thereby increasing
the contact area of the mini stepper with the ground, so that the
mini stepper is supported on the ground rigidly and stably, thereby
facilitating the user operating the mini stepper.
[0007] Another objective of the present invention is to provide a
mini stepper, wherein the mini stepper has a larger contact area
with the ground, so that the weight of the user is distributed from
the mini stepper to the ground evenly and smoothly, thereby
increasing the lifetime of the mini stepper.
[0008] A further objective of the present invention is to provide a
mini stepper, wherein the support rack is detachably mounted on the
base without having to combine the support rack with the base by
soldering, thereby enhancing the aesthetic quality of the mini
stepper, and thereby reducing the procedure of fabrication.
[0009] A further objective of the present invention is to provide a
mini stepper, wherein the support rack is detachably mounted on the
base, thereby facilitating storage, package and transportation of
the mini stepper.
[0010] A further objective of the present invention is to provide a
mini stepper, wherein the sharp end of the fitting portion of the
base is covered by the mounting portion of the support rack, so
that the user can operate the mini stepper safely.
[0011] In accordance with the present invention, there is provided
a mini stepper, comprising:
[0012] a base;
[0013] a shaft tube having a first end secured on a first end of
the base; and
[0014] a support rack detachably mounted on a second end of the
base.
[0015] Further benefits and advantages of the present invention
will become apparent after a careful reading of the detailed
description with appropriate reference to the accompanying
drawings.

DETAILED DESCRIPTION OF THE INVENTION
[0022] Referring to the drawings and initially to FIGS. 1-4, a mini
stepper in accordance with the preferred embodiment of the present
invention comprises a base 12, a shaft tube 11 having a first end
secured on a first end of the base 12, a support rack 21 detachably
mounted on a second end of the base 12, two pedals 10 each having a
first end pivotally mounted on a second end of the shaft tube 11,
and two hydraulic mechanisms 13 each having a first end pivotally
mounted on the first end of the base 12 and a second end pivotally
mounted on a second end of a respective one of the two pedals
10.
[0023] The second end of the base 12 is formed with a fitting
portion 14, and the support rack 21 has a first end formed with a
hollow mounting portion 210 detachably mounted on the fitting
portion 14 of the base 12 and has a second end formed with a
substantially V-shaped extension 211. The extension 211 of the
support rack 21 is an arcuate concave body and is extended outward
from the mounting portion 210 of the support rack 21 in an oblique
downward manner.
[0024] The mini stepper further comprises a support member 20
mounted on a connection of the first end of the shaft tube 11 and
the first end of the base 12. The support member 20 has a center
formed with an arcuate mounting portion 22 mounted on the first end
of the shaft tube 11. The mounting portion 22 of the support member
20 has a periphery formed with two radially opposite stands 24.
Preferably, each of the two stands 24 of the support member 20 is
arc-shaped, and is extended outward from the mounting portion 22 of
the support member 20 in an oblique downward manner.
[0025] As shown in FIGS. 4 and 5, the extension 211 of the support
rack 21 is extended outward from the mounting portion 210 of the
support rack 21 in an oblique downward manner, and each of the two
stands 24 of the support member 20 is extended outward from the
mounting portion 22 of the support member 20 in an oblique downward
manner, thereby increasing the contact area of the mini stepper
with the ground, so that the mini stepper is supported on the
ground rigidly and stably, thereby facilitating the user operating
the mini stepper. In addition, the mini stepper has a larger
contact area with the ground, so that the weight of the user is
distributed from the mini stepper to the ground evenly and
smoothly, thereby increasing the lifetime of the mini stepper.
Further, the support rack 21 is detachably mounted on the base 12
without having to combine the support rack 21 with the base 12 by
soldering, thereby enhancing the aesthetic quality of the mini
stepper, and thereby reducing the procedure of fabrication.
Further, the support rack 21 is detachably mounted on the base 12,
thereby facilitating storage, package and transportation of the
mini stepper. Further, the sharp end of the fitting portion 14 of
the base 12 is covered by the mounting portion 210 of the support
rack 21, so that the user can operate the mini stepper safely.
[0026] 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.
