Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a stationary exerciser, and
more particularly to a stationary exerciser including an improved
structure adjustable to different moving stroke for different users
or according to the users' requirement.
[0003] 2. Description of the Prior Art
[0004] Typical stationary exercisers comprise a pair of foot
supports or foot pedals including one end pivotally or rotatably
attached or coupled to a base support with a pair of cranks, and
including the other end slidably engaged on and supported by a pair
of trails or tracks.
[0005] For example, U.S. Pat. No. 5,352,169 to Eschenbach discloses
one of the typical exercise machines also comprising a base support
including two rotatable cranks pivotally or rotatably attached or
coupled to one end of two elongate pedals by crank pins, and the
elongate pedals each include the other end slidably engaged on and
supported by a trail or track.
[0006] However, the trails or tracks are stationarily disposed or
supported on the base support and may not be adjust to different
angular positions relative to the base support, such that the
elongate pedals of the typical exercise machines may not be
adjusted to different moving strokes.
[0007] U.S. Pat. No. 5,772,558 to Rodgers, Jr. discloses another
apparatus also comprising two reciprocating members including one
end pivotally or rotatably attached or coupled to a base with
cranks and a pulley, and including the other end slidably engaged
on and supported by rollers or slidably engaged with the lower
portion of a frame.
[0008] However, similarly, the lower portion of the frame is also
stationarily disposed or supported on the base and may not be
adjusted or moved or tilted to different angular positions relative
to the base such that the reciprocating members of the typical
stationary exercise apparatus also may not be adjusted to different
moving strokes.
[0009] U.S. Pat. No. 5,846,166 to Kuo discloses a further typical
stepping exercise machine also comprising two foot supports
including one end pivotally attached or coupled to a pair of
handles respectively, and including the other end slidably engaged
on and supported by a pair of tracks.
[0010] However, similarly, the tracks are also stationarily
disposed or supported on the base and may not be adjust to
different angular positions relative to the base such that the foot
supports of the typical stationary exercise apparatus also may not
be adjusted to different moving strokes.
[0011] The present invention has arisen to mitigate and/or obviate
the afore-described disadvantages of the conventional stationary
exercisers or machines.
SUMMARY OF THE INVENTION
[0012] The primary objective of the present invention is to provide
an exerciser including an improved structure adjustable to
different moving stroke according to the users' requirement for
allowing the users to conduct the stepping or walking exercise with
different or suitable moving strokes.
[0013] In accordance with one aspect of the invention, there is
provided an exerciser comprising a base, two rails pivotally
attached to the base and rotatable relative to the base to
different angular positions, two handles pivotally attached to the
base and rotatable relative to the base, two foot supports each
including a first end pivotally coupled to the handle, and each
including a second end slidably engaged with the rail, a coupling
device for coupling the handles to the foot supports respectively,
and a tilting device for tilting the rails relative to the base to
different angular positions.
[0014] The foot supports each include a foot pedal pivotally
attached to the foot support with a pivot pin for allowing the foot
pedal to be tilted relative to the foot support. The handles each
include a lower portion, and the coupling device includes two
levers pivotally coupling the lower portions of the handles to the
foot pedals of the foot support respectively.
[0015] The levers each include a free end folded or bent relative
to the lever and perpendicular to the lever and acted as a pivot
rod for pivotally coupling to the foot pedal and offset from the
pivot pin for allowing the foot pedal to be tilted relative to the
foot support by the handles and the levers.
[0016] The tilting device includes a bolt rotatably attached to the
base, and a motor coupled to the bolt for rotating the bolt
relative to the base, and device for connecting the bolt to the
rails. The connecting device includes a follower threadedly engaged
with the bolt for being moved and adjusted along the bolt when the
bolt is rotated by the motor.
[0017] The connecting device includes an arm pivotally attached to
the base and having a rear end movable up and down relative to the
base and pivotally coupled to the follower. The connecting device
includes a coupler secured between the rails, and includes a seat
extended from the coupler and pivotally coupling to the arm with
such as a bar which may be pivotally coupled to a middle portion of
the arm with such as a pivot pin.
[0018] The foot supports each include a roller attached to the
second end of the foot support for slidably engaging with the
rails. The rails each include two rods disposed parallel to each
other, and a link securing the rods together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0026] Referring to the drawings, and initially to FIGS. 1-4, a
stationary exerciser 1 in accordance with the present invention
comprises a base 10 including an upright post 11 extended upwardly
from the front portion 12 thereof for supporting a control box or
control panel 13 and/or for supporting one or more stationary
handgrips 14, and including one or more (such as two) tracks or
rails 15 provided on the rear portion 16 of the base 10, and a
crank device 20 including such as two crank members (not shown) or
a wheel 21 rotatably attached or coupled to the post 11 or the
front portion 12 of the base 10 with a spindle 22 for allowing the
wheel 21 to be rotated relative to the post 11 or the base 10, and
including two eccentric shafts 23 attached or coupled to the wheel
21 and offset from the spindle 22.
[0027] Two foot supports 30 each include a first end or front
portion 31 pivotally or rotatably attached or coupled to the
eccentric shafts 23 for allowing the front portions 31 of the foot
supports 30 to be moved cyclically or circularly in reciprocating
action relative to the base 10 by the wheel 21 and/or the eccentric
shafts 23, and each include one or more rollers 32 rotatably
attached the second end or the rear portion 33 of the respective
foot supports 30 for slidably engaging with the rails 15, and each
include a foot pedal 34 pivotally attached or supported on the foot
support 30 with a pivot pin 35 for allowing the foot pedals 34 or
the foot supports 30 to be moved in an elliptical moving path or
moving stroke relative to the base 10.
[0028] Two handles 40 each include a middle portion 41 pivotally or
rotatably attached or coupled to the post 11 or the base 10 with a
pivot rod 42 (FIG. 2), and each include a hand grip 43 provided on
top thereof for being held or grasped by the users, and each
include a lower portion 44 pivotally attached or coupled to the
foot support 30 with a lever 45, for allowing the handles 40 to be
pivotally coupled to the foot support 30 with the lever 45. The
above-described structure is typical and will not be described in
further details. The levers 45 may include a rear end or a free end
46 bent relative to the lever 45 and acted or operated as a pivot
rod 46 which is pivotally or rotatably attached or coupled to the
foot pedal 34 and offset from the pivot pin 35 for allowing the
foot pedal 34 to be rotated or tilted relative to the foot support
30 with the lever 45 and/or by the handles 40. The levers 45 and
the foot pedals 34 may be formed or acted or operated as a coupling
means or device for pivotally coupling the handles 40 to the foot
supports 30.
[0029] The stationary exerciser 1 in accordance with the present
invention further includes an actuating or adjusting or tilting
means or device 5 for tilting or adjusting the rails 15 relative to
the base 10 to different angular positions (FIGS. 3-6), and thus
for adjusting the foot supports 30 and/or the foot pedals 34 to
different moving strokes relative to the base 10. For example, the
rails 15 are pivotally or rotatably attached or coupled to the rear
portion 16 of the base 10 with an axle 17 for allowing the rails 15
to be pivoted or rotated or adjusted relative to the base 10 to
different angular positions and for allowing the rails 15 to be
tilted or adjusted relative to the base 10 to different angular
positions with or by the tilting device 5.
[0030] As shown in FIGS. 2 and 5, the rails 15 each may include two
rods 18 disposed or arranged parallel to each other and having a
middle portion coupled or secured together with a link 19 for
forming an elongate and stable structure and for slidably engaging
with the rollers 32 that are provided on the rear portion 33 of the
foot supports 30. The tilting means or device 5 includes one or
more (such as two) arms 50 having one end or front end or first end
51 pivotally or rotatably attached or coupled to the base 10 with a
pivot pin 52 and having the other end or rear end or second end 53
(FIGS. 5, 6) movable up and down relative to the base 10. A
threaded member or bolt 54 is rotatably attached or secured to the
base 10 and coupled to a driving device 55, such as a motor 55
which may rotate the bolt 54 relative to the base 10.
[0031] A follower 56 is threaded or engaged with the threaded
member or bolt 54 and is pivotally coupled to the other or second
end 53 of the arm 50 with another pivot pin 57, and the follower 56
is movable or adjustable along the threaded member or bolt 54 when
the threaded member or bolt 54 is rotated or driven by the motor 55
such that the arm 50 may be pivoted or rotated or tilted relative
to the base 10 by the motor 55 and the bolt 54 and the follower 56.
A coupler 60 is straddled or coupled or secured to or between the
rails 15 for securing or coupling the rails 15 together, and
includes a bracket or seat 61 extended or provided on top thereof
for pivotally coupling to the middle portion 58 of the arm 50 with
a bar 62 which is pivotally coupled to the middle portion 58 of the
arm 50 with a further pivot pin 59. The coupler 60 and/or the seat
61 and/or the bar 62 and/or the arms 50 and/or the follower 56 may
be formed or acted or operated as a connecting means or device for
pivotally connecting the motor 55 and/or the bolt 54 to the rails
15.
[0032] In operation, as shown in FIGS. 5 and 6, when the bolt 54 is
rotated or driven by the motor 55, the follower 56 may be moved or
adjusted along the bolt 54 in order to pivot or rotate or tilt or
adjust the arm 50 relative to the base 10 to different angular
positions as shown in FIGS. 3 and 4, such that the movement of the
rollers 32 of the foot supports 30 along the rails 15 may be
adjusted, and such that the foot pedals 34 or the foot supports 30
may be moved or adjusted to different elliptical moving paths or
moving strokes relative to the base 10. It is to be noted that the
typical stationary exercise devices or machines failed to provide a
rail that may be pivoted or rotated or tilted or adjusted relative
to the base 10 to different angular positions.
[0033] Accordingly, the stationary exerciser in accordance with the
present invention includes an improved structure adjustable to
different moving stroke according to the users' requirement for
allowing the users to conduct the stepping or walking exercise with
different or suitable moving strokes.
[0034] 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.
