Actually, thecrank 20 is pivoted to theindex plate 41. - The
keyboard plate tilter 50 comprises anaxle 51 transversely provided at the front side of thesliding rail assembly 10, twolugs 53 fixedly fastened to the bottom side of thekeyboard plate 100 and respectively pivoted to the two distal ends of thetransverse axle 51, andtorsional springs 52 adapted to support thekeyboard plate 100 on thesliding rail assembly 10 in a tilt position. Thetorsional springs 52 are mounted on thetransverse axle 51, each having oneend 521 stopped at the top side of the slidingrail assembly 10 and theother end 522 stopped against the bottom side of thekeyboard plate 100. - The
keyboard plate lock 60 comprises a female locking member, for example, aretaining hole 61 formed in the top side of the sliding rail assembly and spaced from theaxle 51 at a distance, and a male locking member, for example, aretaining bolt 62 fixedly provided at the bottom side of thekeyboard plate 100 and spaced from thecoupling frame 30 at one side opposite to thelugs 53. - Referring to
FIG. 1 again, theindex plate 41 has apivot hole 411 in axial alignment with abarrel 412 at the slidingrail assembly 10. Theindex plate 41 and thebarrel 412 are bilaterally disposed at the top side of the slidingrail assembly 10 and aligned in a line. Thefirst crank element 21 has a first end pivotally coupled to thebarrel 412 and a second end pivotally coupled to thepivot hole 411. Thesecond crank element 22 has one end fixedly axially connected to the second end of thefirst crank element 21 and the other end fixedly mounted with thegrip 23. - Referring to
FIGS. 3A and 3B , thecrank 20 can be moved in transverse direction across thesliding rail assembly 10 relative to thebarrel 412 and theindex plate 41 within a distance L between a first position, namely, the locking position where thefinger 42 is engaged into one locatinghole 43 of theindex plate 41 to stop thecrank 20 from rotation relative to the index plate 41 (seeFIG. 3A ), and a second position, namely, the unlocking position where thefinger 42 is disengaged from the locatingholes 43 of theindex plate 41 and thecrank 20 can be rotated relative to theindex plate 41. - Referring to
FIG. 4A andFIG. 2 again, thefirst crank element 21 is coupled to thesliding slots 31 of thecoupling frame 30, and thetorsional springs 52 impart an upward pressure to thekeyboard plate 100 relative to thesliding rail assembly 10, and therefore, the keyboard plate tilter 50 steadily supports thekeyboard plate 100 on thesliding rail assembly 10 in a tilt angle. - Referring to
FIGS. 4A-4C andFIGS. 3A and 3B again, the user can move thecrank 20 in transverse direction across the slidingrail assembly 10 from the locking position to the unlocking position to disengage thefinger 42 from the locatingholes 43 of theindex plate 41 and then turn thecrank 20 to shift thefinger 42 from one locatinghole 43 to another to adjust the tilt angle of thekeyboard plate 100 relative to thesliding rail assembly 10. When adjusted, thecrank 20 is pulled backwards to engage thefinger 42 into the corresponding locatinghole 43. According to the present preferred embodiment, theindex plate 41 has three locatingholes 43 spaced around thepivot hole 411 at different angles. - Referring to
FIG. 5 andFIG. 4D , the user can move thecrank 20 in transverse direction across thesliding rail assembly 10 from the locking position to the unlocking position to disengage thefinger 42 from the locatingholes 43 of theindex plate 41 and then turn thecrank 20 to the position where thefirst crank element 21 is maintained in parallel to the slidingrail assembly 10. At this time, the user can press thekeyboard plate 100 to force theretaining bolt 62 into engagement with theretaining hole 61, and therefore thekeyboard plate 100 is locked to the slidingrail assembly 10 in a horizontal position so that the user can push thekeyboard plate 100 and the slidingrail assembly 10 back to the inside of the computer desk (not shown). - A prototype of keyboard plate tilt control structure has been constructed with the features of
FIGS. 1-5 . The keyboard plate tilt control structure functions smoothly to provide all of the features discussed earlier. - Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention.
