Description
FIELD OF THE INVENTION
[0001] This is a Continuation-In-Part application of applicant's
former application with application Ser. No. 10/402762, filed Mar.
28, 2003.
BACKGROUND OF THE INVENTION
[0002] A conventional exercise device, such as an elliptical
exerciser or stair climbing exerciser, includes two pedals which
are respectively connected to two respective operation rods. A
distal end of each of the operation rods is connected to one of two
arms which can be pivoted reciprocally when the user's feet step on
the two pedals. The trace of the two pedals is an oval path such
that the muscles of the feet can be exercised during the operation.
The pedals are made large enough so as to meet needs of different
users and the larger the pedal is, the higher manufacturing cost is
required. The mold for making the pedals has to be bulky and the
travel of the plastic injection machine is also long, both of the
two factors affect the cost of the manufacture. The number of the
pedals that one process of plastic injection can produce is limited
because of the size of the pedals and the cooling period is
increased between two adjacent injections.
[0003] The present invention intends to provide an adjustable pedal
assembly wherein the pedal can be adjusted along the rod according
different needs.
SUMMARY OF THE INVENTION
[0004] The adjustable pedal assembly for exercise devices comprises
a pedal assembly which comprises a pedal having a longitudinal
passage defined therethrough and a rod extends through the passage.
A plurality of first positioning holes are defined through one side
of the peal and a plurality of second positioning holes are defined
in one side of the rod. Two pins each have a head and a shank. The
pins extend through the aligned first positioning holes and second
positioning holes to position the pedal relative to the rod.
[0005] 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.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is an exploded view to show the pedal assembly of the
present invention;
[0007] FIG. 2 is a side view to show the pedal assembly is used for
an elliptical exerciser;
[0008] FIG. 3 shows a cross sectional view, taken from line A-A in
FIG. 2, of the pedal assembly of the present invention;
[0009] FIG. 4 shows that the pins are pulled out from the second
positioning holes in the rod so that the pedal is movable along the
rod;
[0010] FIG. 5 shows that the pedal is shifted along the operation
rod, and
[0011] FIG. 6 shows a cross sectional view, taken from line B-B in
FIG. 5, of the pedal assembly of the present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0012] Referring to FIGS. 1 to 3, the pedal assembly for an
elliptical exerciser of the present invention comprises a pedal 10
having a rectangular passage 11 defined longitudinally therethrough
and a plurality of first positioning holes 12 are defined through
one side of the peal 10. The pedal 10 is a rectangular pedal and
includes a flat top surface on which user's foot stands.
[0013] A rectangular and hollow rod 20 slidably extends through the
passage 11 and has a plurality of second positioning holes 21
defined in one side thereof. Two pins 30 each have a head 31 and a
shank 32, the pins 30 extending through aligned first positioning
holes 12 and the second positioning holes 21 so as to position the
pedal 10 relative to the rod 20.
[0014] The elliptical exerciser includes two sets of the pedal 10
and the rod 20, wherein the two rods 20 are respectively connected
to two arms 40 which are pivotably connected to a post 50. The two
pedals 10 are movably rested on two rollers 51 on a wheel 52. By
pivoting the two arms 40, the two pedals 10 are alternatively moved
up and down along an elliptical trace. A distance "H1" is defined
between the two respective pins 30 on the two pedals 10. Different
users need different distances "H1" when operating the elliptical
exerciser.
[0015] As shown in FIG. 4, the user may easily pull the two pins 30
out from the second positioning holes 21 and the pedal 10 can
therefore be moved along the rod 20 till the pins 30 are inserted
into the aligned first positioning holes 12 and second positioning
holes 21 as shown in FIG. 6. Referring to FIG. 5, by the above
mentioned way, the pedals 10 can be set at a different position
relative to the rods 20. As shown in FIG. 5, the distance "H2"
between the two respective pins 30 on the two pedals 10 is adjusted
to be less than "H1" so as to need a shorter user's need.
[0016] 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.
