Description
FIELD OF THE INVENTION
[0001] The present invention relates to an exerciser and more
particularly, to a stepping exerciser with gliding pedals.
BACKGROUND OF THE INVENTION
[0002] A conventional stepping exerciser generally includes an
I-shaped base and two rods each have one end thereof pivotably
connected to the base and two pedals are connected to the other two
respective ends of the two rods. Two hydraulic cylinders are
connected between the pedals and the base so that when the user
alternatively steps downward the pedals, the cylinders provides
resistance and the user has to overcome the resistance to move the
pedals downward. Nevertheless, the stepping exerciser can only be
operated in the unchanged and boring way, the displacement in
horizontal direction is less than 5 cm and this is not a
comfortable way to work out. Some exercisers combine an elliptical
exerciser and the stepping exerciser so that the trace for the
user's feet has a wider range of movement. However, such
combination makes the exerciser to be bulky and occupies too much
space.
[0003] The present invention intends to provide a stepping
exerciser which includes two pedals and the pedals can glide along
tow respective rails so that the user's foot can move longer
distance.
SUMMARY OF THE INVENTION
[0004] The present invention relates to an exerciser that comprises
a base having a post extending from a first end thereof and a
transverse bar transversely and pivotably extends through the post.
A first pivot is fixedly connected to the post and a second pivot
is connected to the base. The second pivot is located at a distance
from the post.
[0005] Two link assemblies are located on two sides of the base and
each link assembly has two first link and two second links. The two
first links are located in parallel with each other and have two
respective first ends connected to the first pivot. The two second
links are located in parallel with each other and have two
respective first ends connected to the second pivot. Two cylinders
each have one end connected to the base and the other end of each
of the two cylinders is pivotably connected to a separation bar
connected between the two second links. One of the two first links
of each link assembly is in contact with the transverse bar.
[0006] Two gliding assemblies each have a support member and a
rail. The two rails each have a groove defined therein and the
support members are movably received in the grooves of the two
rails. The two rails are connected to second ends of the first and
second links of each link assembly. Two pedals are fixedly
connected on the support parts.
[0007] The primary object of the present invention is to provide a
stepping exerciser whose pedals can be movable along two respective
rails so that the user's feet can move in horizontal direction.
[0008] The present invention will become more obvious from the
following description when taken in connection with the
accompanying drawings which show, for purposes of illustration
only, a preferred embodiment in accordance with the present
invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0017] Referring to FIGS. 1 to 3, the exerciser 1 of the present
invention comprises an I-shaped base 10 which has a front
transverse leg 101 at a first end of the base 10, a rear transverse
leg 102 at a second end of the base 10 and a central column
connected between the front and rear legs 101, 102. A post 103
extends from the front transverse leg 101 and a display panel 1031
is connected to a top of the post 103. A transverse bar 1032
transversely and pivotably extends through the post 103. A first
pivot 104 is fixedly connected to the post 103. An inclined bar is
connected between the front transverse leg 101 and the central
column and a second pivot 105 is connected to the inclined bar of
the base 10. The second pivot 105 is located at a distance from the
post 103.
[0018] Two link assemblies 11 are located on two sides of the base
10 and each link assembly 11 has two first link 111 and two second
links 112. The two first links 111 are located in parallel with
each other and have two respective first ends connected to the
first pivot 104 by a first shaft 113 located between the two first
ends of the first links 111. The two second links 112 are located
in parallel with each other and have two respective first ends
connected to the second pivot 105 by a second shaft 114 located
between the two first ends of the second links 112. Two cylinders
12 each have one end connected to the rear transverse bar 102 of
the base 10 and the other end of each of the two cylinders 12 is
pivotably connected to a separation bar 116 connected between the
two second links 112. One of the two first links 111 of each link
assembly 11 has a recess 1111 and the transverse bar 1032 is
engaged with the recess 111. Each first link 111 that has the
recess 1111 has a stop bar 1112 connected thereto, and the
transverse bar 1032 is located between the recess 111 and the stop
bar 1112. When the first link 112 with the recess 1111 is pivoted
toward the first end of the base 10, the transverse bar 1032 is
pivoted about a longitudinal axis of the post 103 and the other
link assembly 11 is pivoted toward the second end of the base
10.
[0019] Two connection parts 13 each have a first end pivotably
connected to the first ends of the two first links 111 of each link
assembly 11 by extending a bolt through a hole 115 defined through
the first end of the first link 111 and a separation bar between
the two first links 111 and the fixedly connected to the connection
part 13. A pivotable part 131 is pivotably connected to a second
end of each of the connection part 13. Two connection boards 117
each have a first end connected to the first end of the connection
part 13 and a second end of each of the two connection boards 117
is pivotably connected to the separation bar 116.
[0020] Two gliding assemblies 14 each have a support member 142 and
a rail 141, each of the support members 142 has a first end
pivotably connected to the pivotable part 131. The two rails 141
each have a groove defined therein and the support members 142 are
movably received in the grooves of the two rails 141. As shown in
FIG. 4, two rollers 143 are located in the grooves in the two rails
141 and the support member 142 is smoothly movable in the grooves
by the rollers 143. The two rails 141 are connected to second ends
of the first and second links 111, 112 of each link assembly 11.
Two pedals 15 are fixedly on the support parts 142.
[0021] Referring to FIGS. 5 to 8, the user steps the pedals 15
alternatively and downward and the first links 111 of the two link
assemblies 11 pivot the transverse bar 1032 so that the user has to
overcome the resistance from the two cylinders 12. In the
meanwhile, the pedals 15 can be glided relative to the rails 141
and the feet move in horizontal direction at a sufficient distance
such as 30 cm.
[0022] While we have shown and described the embodiment in
accordance with the present invention, it should be clear to those
skilled in the art that further embodiments may be made without
departing from the scope of the present invention.
