DETAILED DESCRIPTION OF THE INVENTION
[0017] Referring to FIGS. 3-7, an oblong orbital exercising machine
in accordance with the preferred embodiment of the present
invention comprises a main frame 10, an upright 11, two swinging
handles 12, a cycle movement mechanism 13, two tread bars 14, two
sliding bars 15, two pedals 16, two cranks 17, two rollers 18, two
guiding tracks 19, two pivot members 20, and two ball bearings
30.
[0018] The cycle movement mechanism 13 is mounted on the main frame
10. The upright 11 is mounted on a front portion of the main frame
10. Each of the cranks 17 has a first end pivotally connected with
the upright 11. The cranks 17 have different angles. Each of the
sliding bars 15 has a first end pivotally connected with a second
end of a respective one of the cranks 17. Each of the guiding
tracks 19 is mounted on a rear portion of the main frame 10. Each
of the guiding tracks 19 has top face 191. Each of the rollers 18
is mounted on a second end of a respective one of the sliding bars
15 and is slidable forward and backward on the top face 191 of a
respective one of the guiding tracks 19. The top face 191 of each
of the guiding tracks 19 has an arcuate convex shape to correspond
to the respective roller 18. Each of the guiding tracks 19 has two
upward extending side wings 192 formed on two opposite sides
thereof. Preferably, each of the side wings 192 of each of the
guiding tracks 19 is extended upward in an oblique manner from each
of the two opposite sides of each of the guiding tracks 19. Each of
the swinging handles 12 is pivotally connected with the upright 11.
Preferably, the swinging handles 12 are mounted on two opposite
sides of the upright 11. Each of the pivot members 20 is pivotally
connected with a front end of a respective one of the tread bars 14
and has a top portion provided with a threaded rod 21 pivotally
connected with a lower end of a respective one of the swinging
handles 12. Each of the pedals 16 is secured on a respective one of
the tread bars 14. Each of the ball bearings 30 is located between
a respective one of the pivot members 20 and the lower end of a
respective one of the swinging handles 12. Each of the ball
bearings 30 is mounted on the threaded rod 21 of the respective
pivot member 20.
[0019] In practice, when each of the rollers 18 is slidable forward
and backward on the top face 191 of the respective guiding track
19, each of the rollers 18 is guided by the arcuate convex shape of
the top face 191 of the respective guiding track 19, and is limited
by the side wings 192 of the respective guiding track 19, so that
each of the rollers 18 will not be deflected rightward or leftward
during movement, and will not be easily detached from the
respective guiding track 19.
[0020] In assembly, after other parts of the exercising machine are
assembled, the threaded rod 21 of each of the pivot members 20 is
pivotally connected with the lower end of the respective swinging
handle 12. In such a manner, it usually happens that the threaded
rod 21 of each of the pivot members 20 cannot be precisely aligned
with the lower end of the respective swinging handle 12 due to an
angular deflection. At this time, each of the ball bearings 30 is
mounted on the threaded rod 21 of the respective pivot member 20
and is located between the respective pivot member 20 and the lower
end of the respective swinging handle 12 to compensate the angular
deflection between the threaded rod 21 of the respective pivot
member 20 and the lower end of the respective swinging handle 12 so
that the threaded rod 21 of the respective pivot member 20 and the
lower end of the respective swinging handle 12 are screwed and
connected exactly and efficiently.
[0021] Accordingly, when each of the rollers 18 is moved on the
respective guiding track 19, each of the rollers 18 is guided by
the top face 191 of the respective guiding track 19, and is limited
by the side wings 192 of the respective guiding track 19, so that
each of the rollers 18 will not be deflected rightward or leftward
during movement, and will not be easily detached from the
respective guiding track 19 to facilitate movement of the rollers
18. In addition, when the threaded rod 21 of each of the pivot
members 20 cannot be precisely aligned with the lower end of the
respective swinging handle 12 due to an angular deflection, each of
the ball bearings 30 on the threaded rod 21 of the respective pivot
member 20 is located between the respective pivot member 20 and the
lower end of the respective swinging handle 12, so that the
threaded rod 21 of the respective pivot member 20 and the lower end
of the respective swinging handle 12 are connected exactly and
efficiently without incurring detachment.
[0022] 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.
