FIGS. 1, 2 , and 3, a sliding keyboard carrier is shown comprised of abase frame 10, asliding plate 20, apositioning structure 30, and ahandle frame 41. - The
base frame 10 comprises twoupright rods 11, acarrier frame bar 14, and two locatingrods 16. Thecarrier frame bar 14 is a substantially U-shaped frame bar, having a smoothlyarched middle part 141 horizontally disposed at the front side. The two free ends of the U-shapedcarrier frame bar 14 are disposed at the rear side and respectively fixedly connected to the bottom ends of theupright rods 11. Thecarrier frame bar 14 is affixed to the bottom side of akeyboard panel 200 for carrying a keyboard in a computer table (see alsoFIGS. 6 and 7 ). The locatingrods 16 are respectively perpendicularly extended from the top ends of theupright rods 11 in direction reversed to the U-shapedcarrier frame bar 14, each having a plurality of throughholes 161. - The
sliding plate 20 comprises a plurality of verticalfemale screws 21 downwardly extended from the bottom side and respectively inserted through respective the throughholes 161 of the locatingrods 16 and then affixed thereto withrespective screws 22, a plurality ofhorizontal roller holders 23 symmetrically disposed at two opposite lateral sides, and a plurality ofrollers 24 respectively fastened pivotally with theroller holders 23 and supported in twoparallel rails 25 in the computer table for enabling the sliding keyboard carrier to be moved back and forth along therails 25. - The
positioning structure 30 comprises avertical spring support 31, alocking bar 35, and two locating plates 36 (see also FIGS. 4˜7). Thevertical spring support 31 comprises two cylindricalouter barrels 32 respectively affixed to theupright rods 11 of thebase frame 10 below the locatingrods 16, two cylindricalinner barrels 33 respectively affixed to thelocking bar 35 and respectively movably inserted into theouter barrels 32 from the top side, and twocompression springs 34 respectively mounted in between theouter barrels 32 and theinner barrels 33. Thelocking bar 35 has two distal ends symmetrically curved upwards and terminating in arespective locking tip 351. The two locatingplates 36 are respectively affixed to therails 25 near the front side of thetable frame 100 of the computer table, each having alocking hole 361 adapted to receive thelocking tips 351 of the locking bar 35 (this will be described further). The locatingplates 36 have a respective rear side curved upwards. - The
handle frame 41 is pivotally provided between the twoupright rods 11, comprising ashaft 42 horizontally connected between theupright rods 11, asleeve 43 sleeved onto theshaft 42 before installation of theshaft 42, and a substantiallyU-shaped handlebar 411 fixedly fastened to thesleeve 43. Thehandlebar 411 has twofree ends 412 respectively pressed on thelocking bar 35. Further, one locatingrod 16 is provided with apressure pin 162, which is pressed on onefree end 412 of thehandlebar 411 against thelocking bar 35, holding thehandle frame 41 in position. - As illustrated in
FIG. 3 , t thebase frame 10 is coupled to therails 25 below the tabletop frame member 200 by means of therollers 24. Therails 25 each have anopening 251. During installation, therollers 24 are respectively inserted through theopenings 251 in therails 25 and fastened to theroller holders 23 of thesliding plate 20.FIG. 3 shows the outer appearance of the tabletop frame member 100, and ashield 101 covering the rails 25 (see alsoFIG. 5 ). - As illustrated in
FIGS. 3 and 4 , by means of therollers 24, thebase frame 10 can be moved back and forth along therails 25. When pulling thebase frame 10 outwards, thecarrier frame bar 14 with thekeyboard panel 200 are moved out of the front side of the tabletop frame member 100 for operation. On the contrary, when pushing thebase frame 10 backwards, thecarrier frame bar 14 with thekeyboard panel 200 are received below the tabletop frame member 100. -
