Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention The present invention relates to
an exercising machine and, more particularly, to an exercising
machine with an oblong orbit or cycle.
[0002] 2. Description of the Related Art
[0003] A conventional oblong orbital exercising machine in
accordance with the prior art shown in FIG. 1 comprises a main
frame 51, an upright post 54 mounted on the front portion of the
main frame 51, two swinging handles 55 each having an upper end
pivotally connected with the upright post 54, a freewheel 52
mounted on the rear portion of the main frame 51, two pivot members
53 mounted on two opposite sides of the freewheel 52, two links 56
each having a first end pivotally connected with the lower end of a
respective one of the swinging handles 55 and a second end
pivotally connected with a respective one of the pivot members 53,
and two pedals 57 each mounted on a respective one of the links 56.
In operation, when a user operates the exercising machine, his
hands hold the swinging handles 55 to move the swinging handles 55
and his feet tread the pedals 57 to move the links 56. In such a
manner, the links 56 are driven by rotation of the freewheel 52 and
by pivotal motion of the swinging handles 55 so as to perform an
oblong orbit movement so that the user can exercise his hands and
legs efficiently. However, each of the links 56 is located between
the respective swinging handle 55 and the respective pivot member
53 so that each of the links 56 has a fixed movement trace that
cannot be adjusted according to the user's requirement, thereby
limiting the exercising effect of the exercising machine.
BRIEF SUMMARY OF THE INVENTION
[0004] In accordance with the present invention, there is provided
an exercising machine, comprising a main frame, an upright post
mounted on a front portion of the main frame, two swinging handles
each having an upper end pivotally connected with the upright post,
a cycle movement mechanism mounted on a rear portion of the main
frame, two shafts respectively secured on two opposite sides of the
cycle movement mechanism, two adjusting units each mounted on a
respective one of the shafts, two links each having a first end
pivotally connected with a lower end of a respective one of the
swinging handles and a second end pivotally connected with a

DETAILED DESCRIPTION OF THE INVENTION
[0018] Referring to the drawings and initially to FIGS. 2-6, an
oblong orbital exercising machine in accordance with the preferred
embodiment of the present invention comprises a main frame 10, an
upright post 101 mounted on a front portion of the main frame 10,
two swinging handles 13 each having an upper end pivotally
connected with the upright post 101, a cycle movement mechanism 11
mounted on a rear portion of the main frame 10, two shafts 12
respectively secured on two opposite sides of the cycle movement
mechanism 11, two adjusting units 20 each mounted on a respective
one of the shafts 12, two links 14 each having a first end
pivotally connected with a lower end of a respective one of the
swinging handles 13 and a second end pivotally connected with a
respective one of the adjusting units 20, and two pedals 142 each
mounted on a respective one of the links 14.
[0019] The shafts 12 misalign with each other and are located at
different positions of the cycle movement mechanism 11. Each of the
shafts 12 is eccentrically mounted on the cycle movement mechanism
11. The swinging handles 13 are located at two opposite sides of
the upright post 101.
[0020] Each of the adjusting units 20 includes a fixing member 30
mounted on the respective shaft 12 and having a surface provided
with a plurality of adjusting holes 31, an adjusting member 40
juxtaposed to the fixing member 30, and a positioning member 41
mounted on the adjusting member 40 and adjustably locked in one of
the adjusting holes 31 of the fixing member 30.
[0021] The fixing member 30 of each of the adjusting units 20 has a
disk shape and is fixed on the respective shaft 12 by a screw.
[0022] The adjusting member 40 of each of the adjusting units 20
has a disk shape and is pivotally connected with the second end of
the respective link 14. The adjusting member 40 of each of the
adjusting units 20 is rotatably mounted on the respective shaft 12
so that the adjusting member 40 of each of the adjusting units 20
is rotatable relative to the fixing member 30. The adjusting member
40 of each of the adjusting units 20 is coaxial with the fixing
member 30.
[0023] The positioning member 41 of each of the adjusting units 20
is movably mounted on the adjusting member 40 and is detachably
mounted in one of the adjusting holes 31 of the fixing member 30.
Preferably, the positioning member 41 of each of the adjusting
units 20 is pin, latch or bolt.
[0024] Each of the adjusting units 20 further includes a connecting
member 42 mounted on the adjusting member 40. The connecting member
42 of each of the adjusting units 20 is a rod and is eccentrically
secured on the adjusting member 40. The second end of each of the
links 14 is provided with a pivot portion 141 pivotally connected
with the connecting member 42 of the respective adjusting unit 20.
The pivot portion 141 of each of the links 14 is a mounting tube
and is mounted on the connecting member 42 of the respective
adjusting unit 20.
[0025] In operation, again referring to FIGS. 2-6, when a user
wishes to operate the exercising machine, he can stand on the
exercising machine, with his hands holding and pivoting the
swinging handles 13, and with his feet treading the pedals 142 to
move the links 14. In such a manner, the links 14 are driven by
rotation of the cycle movement mechanism 11 and by pivotal motion
of the swinging handles 13 so as to perform an oblong orbit
movement so that the user's hands and legs are moved forward and
backward in a reciprocal manner so as to exercise his hands and
legs. Thus, the links 14 and the adjusting units 20 are driven by
the swinging handles 13 to move forward and backward.
[0026] In adjustment, referring to FIGS. 7-10 with reference to
FIGS. 2-6, the positioning member 41 of each of the adjusting units
20 is detached from one of the adjusting holes 31 of the fixing
member 30 so that the adjusting member 40 of each of the adjusting
units 20 is unlocked from the fixing member 30 and can be rotated
freely. Then, each of the links 14 is moved to drive the adjusting
member 40 of each of the adjusting units 20 so that the adjusting
member 40 of each of the adjusting units 20 is rotated relative to
the fixing member 30 to a determined position. Then, the
positioning member 41 of each of the adjusting units 20 is inserted
into and locked in another one of the adjusting holes 31 of the
fixing member 30 so that the adjusting member 40 of each of the
adjusting units 20 is locked onto the fixing member 30 and cannot
be moved any more. In such a manner, the positioning member 41 of
each of the adjusting units 20 is adjustably locked in any one of
the adjusting holes 31 of the fixing member 30, so that each of the
links 14 is located at different positions as shown in FIGS. 7-10
to change the positions and angles of each of the swinging handles
13 so as to provide different movement traces, thereby diversifying
the exercising effect of the exercising machine.
[0027] Accordingly, the adjusting member 40 of each of the
adjusting units 20 is rotated relative to the fixing member 30, and
the positioning member 41 of each of the adjusting units 20 is
locked in any one of the adjusting holes 31 of the fixing member
30, so that each of the links 14 is driven to change the position
and angle of each of the links 14 and each of the swinging handles
13 so as to adjust the movement trace of each of the links 14 and
each of the swinging handles 13, such that the exercising machine
has multiple different movement traces, thereby diversifying and
enhancing the exercising effect of the exercising machine.
[0028] 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.
