(b) Description of the Prior Art
- SUMMARY OF THE INVETION
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.
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.
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.
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.
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 itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings. Throughout the specification and drawings identical reference numerals refer to identical or similar parts.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIENT
FIG. 9 is a further preferred embodiment showing the disengagement of the gear section with the gear stripe in accordance with the present invention.
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.
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.
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.
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.
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.
