Description
BACKGROUND OF THE INVENTION
[0001] (a) Technical Field of the Invention
[0002] The present invention relates to seat pad adjusting device,
and in particular, the seat pad of an actuating seat of an
exerciser being adjustable for individual user of different height
and size.
[0003] (b) Description of the Prior Art
[0004] FIGS. 1, 2 and 3 are conventional exercisers which are
commonly used by people of different heights and sizes. Due to the
facts that the height and the lengths of hands and legs are
different from one another, the actuating seat 2 of the fixing seat
1 has to be adjusted, and the seat pad 23 has to be moved either
forward or backward. A mounting element 12 is mounted below the
fixing seat 1, and a pulling rod 11 having a blocking section 14 at
the middle section thereof is provided to the mounting element 12.
An elastic element 13 which can be pushed upward is positioned
between the blocking section 14 and the mounting element 12 such
that the positioning peg 15 at the front end of the pulling rod 11
can engage with the positioning hole 21 within the actuating seat
2. In order to cause the actuating seat 2 to slide into the fixing
seat 1, the fixing seat 1 is provided with T-shape finger 10 to
engage into the sliding slot 20 at the two sides of the actuating
seat 2. Most of the conventional exercisers are provided with
equidistant positioning hole 21 within the actuating seat 2. For
the positioning peg 15 on the pulling rod 11 to be able to engage
with the hole 21, it requires some time to adjust and many outside
the distant range, and the adjustment has to be made beneath the
actuating seat 2, which is laborious. Further, in order for the
positioning peg 15 to engage or adjust (as shown in FIG. 4), the
pulling rod 11 is downward pulled and the actuating seat 2 is
aligned with the elastic element 13 to urge the actuating seat 2.
The seat pad 23 on the actuating seat 2 may be dislocated when a
great force impacts onto the exerciser. Accordingly, it is an
object of the present invention to provide a seat pad adjusting
device of an exerciser which mitigates the above drawbacks.
SUMMARY OF THE INVETION
[0005] A main object of the present invention is to provide a seat
pad adjusting device of an exerciser having a fixing seat allowing
slidably adjustment of the seat pad to a stable position,
characterized in that the fixing seat having a finger portion is
provided with an actuating seat for engagement with a sliding slot,
and the lower section of the fixing seat is mounted with a mounting
element and the interior of the fixing seat is disposed with a
rotating shaft, and the mounting element is provided with a first
gear section and the rotating shaft is provided with another gear
section for engagement with the first gear section, the upper end
of the rotating shaft is provided with a gear portion and the
interior of the actuating seat is provided with an elongated gear
stripe for gear engagement, thereby the rotating of the rotating
shaft causes the gear portion to engage or disengage so that the
actuating seat is slidably adjusted.
[0006] A further object of the present invention is to provide a
seat pad adjusting device of an exerciser, wherein the interior of
the gear portion is provided with a T-shape displacement chamber
and the upper end of the rotating shaft is disposed with a holding
end which mount with the rotating shaft and provides upward and
downward displacement of the gear portion, and an elastic element
with compression springs is positioned between the mounting element
and the gear portion, thereby the rotating shaft can be pulled
downward and the elastic element and the screw section are engaged
such that the upward and downward of the gear portion causes the
gear stripe to disengage or to engage with the positioning screw
nut.
[0007] Still another object of the present invention is to provide
a seat pad adjusting device of an exerciser, wherein the seat pad
can be adjusted to any position and can steadily slide for
adjustment.
[0008] The foregoing object and summary provide only a brief
introduction to the present invention. To fully appreciate these
and other objects of the present invention as well as the invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIENT
[0019] The following descriptions are of exemplary embodiments
only, and are not intended to limit the scope, applicability or
configuration of the invention in any way. Rather, the following
description provides a convenient illustration for implementing
exemplary embodiments of the invention. Various changes to the
described embodiments may be made in the function and arrangement
of the elements described without departing from the scope of the
invention as set forth in the appended claims.
[0020] Referring to FIGS. 5, 6 and 7, there is shown a seat pad
adjusting device of an exerciser. The fixing seat 1 is provided
with a T-shape finger portion 10, and the lower section of the
fixing seat 1 is provided with a mounting element 17 having a gear
section 171. The mounting element 17 is provided with a rotating
shaft 16 having a gear section 161 and the upper section of the
rotating shaft 16 is mounted with a gear portion 18. For slidably
engagement of the finger portion 10 of the fixing seat 1 the fixing
seat 1 is provided with an actuating seat 2 which can slide forward
and backward. The actuating seat 2 is to engage with the finger
portion 10 of the fixing seat 1, the two lateral sides of the
actuating seat 2 are provided with the sliding slot 20, and the
interior of the actuating seat 2 is provided with an elongated gear
stripe 22 for the engagement of the gear portion 18 at the top end
of the rotating shaft 16 so that the exerciser can be adjusted to a
most comfortable position. In adjusting the present device of the
present invention, the rotating shaft 16 is rotated such that the
two gear sections 161, 171 move in opposite direction such that the
engaged gear portion 18 with the gear stripe 22 (as shown in FIG.
5) are disengaged (in the direction of the arrow). At this
instance, the actuating seat 2 will be adjusted to move forward or
backward (in the direction of the arrow). When the actuating seat 2
is pushed to position, the rotating shaft 16 is rotated in the
opposite direction so that the disengaged elongated gear stripe 22
with the gear portion 18 is engaged again, and when it is engaged
the gear stripe 22 will not be dislocated. The elongated gear
stripe 22 includes the entire actuating seat 2 and therefore the
adjusting range is large. At the same time, the teeth on the gear
stripe 22 are densely arranged and therefore alignment of the gear
on the gear stripe 2 can be obtained easily.
[0021] As shown in FIGS. 8 and 9, there is shown the disengagement
of gear portion 18 with the gear stripe 22. The gear portion 18 is
provided with a T-shape displacement chamber 181 and the rotating
shaft 16 is provided with a T-shape holding end 162 at the upper
end of the rotating shaft 16 so that the gear portion 18 can be
moved up and down. At the same time, in order to maintain the
upward push force, in between the lower portion of the gear portion
18 and the mounting element 17, an elastic element 163 having a
compression spring is provided, such that when the rotating shaft
16 is locked, the upper end of the holding end 162 will push the
gear portion 18 and is in engagement with the elongated gear stripe
22. In the course of engagement, the rotating shaft 16 is rotated
and is pulled downward such that the gear portion 18 and the gear
stripe 22 are disengaged with each other (as shown in FIG. 9). At
this moment, the actuating seat 2 can be optionally slidably
adjusted to an appropriate position. When the rotating shaft 16 is
pulled downward, the elastic element 163 pushes upward the gear
portion 18 and is again, engaged with the elongated gear stripe 22.
After that, the rotating shaft 16 is locked with the gear section
161, 171 of the mounting element 17, as shown in FIG. 8.
[0022] It will be understood that each of the elements described
above, or two or more together may also find a useful application
in other types of methods differing from the type described
above.
[0023] While certain novel features of this invention have been
shown and described and are pointed out in the annexed claim, it is
not intended to be limited to the details above, since it will be
understood that various omissions, modifications, substitutions and
changes in the forms and details of the device illustrated and in
its operation can be made by those skilled in the art without
departing in any way from the spirit of the present invention.
